Introduction:

The evolution of the automobile industry has been marked by continuous advancements in technology and manufacturing processes. From Carl Benz's invention of the first car in 1886 to Henry Ford's revolutionary assembly line in 1908, the industry has seen significant improvements in efficiency and production techniques. One critical aspect of automobile manufacturing is the painting process, which has evolved from simple air-dry varnish techniques to sophisticated multi-step procedures. This paper reviews the historical developments in automotive paint technology and explores the application of nano-cell-based solar imprints on the top-coat surface of EVs, aiming to improve energy efficiency and sustainability.

Carl Benz invented the first car in 1886, which Emile Lavassor subsequently remodeled with the engine at the front. Ransom Eli Olds used automated production to build cars in 1901, but Henry Ford's Model T transformed manufacturing in 1908. Ford's unique assembly line, which included separate stations and a moving line, reduced production time to 90 minutes. This strategy, in which workers stayed fixed, is still used in modern automobile assembly, demonstrating Ford's long-lasting influence on the industry.

The car production process is divided into numerous stages, beginning with the vehicle's design and engineering, considering public preferences, including cutting-edge technology, and assuring aesthetic appeal. Following that, the acquisition of raw materials prioritizes sustainability and cost-effectiveness. The obtained materials are stamped or pressed at the Press shop to create sheet metal components such as doors, roofs, and side frames. These parts are subsequently combined in the Body Shop to create the single-body structure (BIW). The paint shop ensures a dust-free atmosphere in which to apply numerous coats of protective coatings on the BIW, providing the best results. The trim line assembly is the next process, which involves putting together trim elements, insulation, and the car's interior. The car next travels to the mechanical line, the core of the manufacturing process, where all mechanical components, including the engine and tires, are assembled. In the last phase, thorough checks and tests are carried out to assure quality and safety.of Form

Paint application is one of the most challenging aspects of automobile manufacturing. The paint not only protects the body surface but also enhances its visual appeal. Enhance visual appeal by using shade and gloss - crucial selling points. The innovation used must meet high criteria of quality and cost-effectiveness while also being environmentally sustainable. Cutting-edge improvements in all important fields, together with our expertise in coordination, allow us to offer top-quality and cost-effective turnkey systems. As a General Contractor, we take responsibility for scheduling, project expenses, plant implementation, and the construction and its services. Car paint is used on cars for protection and decoration. Currently, water-based acrylic polyurethane lacquer paint is the most widely used paint due to its ability to reduce the environmental impact of painting.

The main organizational framework of this review study is as follows. The introduction to the painting technologies and its development with industrial evolution. Based on this, a review covers the literature pertaining to important paint shop methodologies and prospective applications of nano cell-based surface coating on automobiles. This technology analyses the steps involved in implementing important technologies and reviews pertinent literature on the use of emerging nano solar applications. The possible practical significance of nano solar imprints in paint shop and the ensuring research direction are anticipated by Discussion and Prospect. The conclusion provides an overview and reference for the informed development of the manufacturing sector by summarizing the review's findings.

Painting Technologies in Automobiles:

Since the late 1800s, the automobile paint technology has made significant breakthroughs since the manufacturing of the first cars. Automotive paint in the early 20th century was constrained by the technology available at that time, mostly utilizing air-dry varnish techniques that were originally designed for hardwood furniture and horse-drawn carriages. Yet, this method had notable disadvantages such as restricted shade choices and a laborious application procedure that required repetitive brush applications and prolonged drying times, leading to manufacturing delays.

During the late 1800s to the early 1900s, acquiring appropriate automotive paints was difficult due to the recent development of cars. People painted their automobiles by hand using brushes and paints that were readily accessible in their area. Regrettably, the paint would quickly fade and crack, necessitating repeated repainting. By 1900, car manufacturers began using carriage varnishes, which required a time-consuming coating process of up to 40 days per vehicle. Following the drying process, more procedures such as sanding and polishing were required.

In the mid-1900s, Dr. George Sargent undertook pioneering research that revolutionized car paint technology. His research was on electroplating chrome and identified a crucial ratio of one-part sulfuric acid to 100 parts chromium. The discovery, outlined in a 1920 publication, was a crucial moment in the field, leading to progress in chrome finishes and influencing the development of automobile paint systems.

In the 1930s, vehicle paint technology saw a tremendous revolution with the adoption of stoving veneers by manufacturers. These paints are well-known for creating shinier surfaces and greatly decreasing drying times, successfully overcoming the limitations of previous painting methods. This innovation enhanced the aesthetic appeal of cars and optimized the manufacturing process, leading to increased efficiency and faster production timelines. Dr. William Peacock significantly advanced the chromium field by creating a silvering spray during this time. The 1932 invention was initially designed for silvering mirrors but ended up transforming mirror manufacture by significantly cutting prices and improving availability. Dr. Peacock's progress has a wide-reaching impact, not limited to the automobile industry, highlighting the interconnectedness of technology advancements in today's dynamic times.

Fast-forward to 1955, General Motors ushered in a substantial change in automotive paint technology by introducing a new acrylic paint for their vehicles. This advanced paint necessitated a heating process after application to get a consistent and even surface. Although effective, it did not reach the same level of reflecting brightness as stoving polishes. General Motors advanced paint application procedures. Ford Motor Co. advanced the advancement by including acrylic stoving lacquers into their manufacturing process by 1960. This intentional action was taken to improve the shiny look of their cars, showcasing the ongoing progress and rivalry in the automotive paint industry during this changing period.

Today, vehicle painting has developed into a sophisticated, multi-step process that takes environmental factors into account. The modern car paint system consists of six separate layers, each applied individually to offer corrosion resistance, durability, and vivid color. The layers are precisely prepared to attach flawlessly, creating a robust coating that is resistant to flaking or peeling. The evolution from simple varnish systems to the current environmentally important procedure highlights the continuous advancements in automotive paint technology. As the industry progresses, there is a continuous focus on reconciling the need for high-performance coatings with environmental sustainability to ensure that our cars are both physically attractive and environmentally friendly.

Historical Advancements in Automotive Paint Technology

In the early 20th century, automotive paint was primarily air-dry varnish, which had limited color options and required multiple brush applications. The process was time-consuming and often resulted in manufacturing delays. By the 1930s, stoving enamels were introduced, reducing drying times and enhancing the aesthetic appeal of vehicles. Significant contributions from researchers like Dr. George Sargent and Dr. William Peacock further advanced the field with innovations in electroplating and silvering sprays, respectively.

Modern Automotive Paint Systems

Today's automotive paint process involves multiple layers, including pre-treatment, electrodeposition, primer, basecoat, and clearcoat. Each layer serves a specific function, from corrosion resistance to providing a durable and visually appealing finish. Modern paint technologies focus on reducing environmental impact through the use of water-based acrylic polyurethane lacquer and other sustainable materials.

Painting Process:

The automotive paint shop is a complex setting where a detailed process is carried out to produce visually striking vehicles while providing strong protection against environmental factors. In the paints and coatings industry, there are several roles, from high-volume original equipment manufacturers (OEMs) with automated systems to custom shops that do contract work with manual equipment.

The painting process is governed by five key methods: pre-treatment and electrodeposition (ED), ED sanding, sealant and PVC line application, primer, and topcoat. Car paints have a dual function: determining hues and aesthetics while also offering essential protection against corrosion and weathering. Conventional paint films, approximately the thickness of a human hair, are composed of four layers.

The car body is prepared, immersed in an electrocoat, then coated with a primer in a typical technique to guard against corrosion. The layers are subsequently burned onto the surface using an oven. After applying the basecoat for color and the clearcoat for aesthetics and scratch resistance, the composition process is completed with another round of oven heating.

The Pre-Treatment and Electro Dip (PTED) procedure plays a crucial role in creating a rust-resistant base using contemporary technology. This treatment greatly improves the vehicle's ability to resist corrosion, therefore increasing its longevity and strength. The next phase includes a regulated curing process in an oven setting to guarantee the best adhesion and strengthening of the protective coatings.

The sealant is applied with precision and carefully inspected by an auditor to ensure thorough evaluation and necessary repairs on the sealant bead. Thorough supervision is crucial for ensuring the effective and long-lasting incorporation of the protective barrier. The following primer application is a crucial step that necessitates meticulous preparation. An automated system ensures accurate flange masking for outside surfaces, while skilled operators supervise the process for interior surfaces. The BASE coat determines the color identity of the car, while the topcoat improves shine and luster, improving visual attractiveness.

It is crucial to place the coated object back into a controlled oven environment to ensure the curing process, which creates a durable bond with the vehicle's surface. In the last steps, polishing procedures are used to enhance the surface finish, and wax is carefully applied, including cavity filling processes to fix any faults.

The meticulous and refined method in the paint shop goes beyond just looks, demonstrating a dedication to excellence and the quest for perfection. The completed car coating showcases visual beauty and the combination of talent and strength in this precise operation.

2. Problem background:

Henry Ford invented the moving assembly line in 1914, which cut the production time from 12.5 hours to 93 minutes. One car departed the line every three minutes, using fewer laborers than previously (Georgano, 1985). The

The purchaser may choose from a variety of bodywork options, although there weren't many paint colors available. In 1909, Ford informed his management staff that going forward, "Any customer can have a car painted any color that he wants so long as it is black," according to his autobiography (Ford & Crowther, 1922). Nevertheless, the Model T was not offered in black during its initial years of manufacture, from 1908 to 1913 (McCalley, 1994). Instead, it was offered in a variety of colors, depending on the kind of car: gray for town cars, red for touring cars, and green for coupes and Landaulets (as well as certain town and touring vehicles). All automobiles had midnight blue paint and black fenders by 1912. Only in 1914 was the one-color notion eventually put into practice. From 1914 to 1926, Ford recommended the use of black paint, most likely because of its affordability and longevity. A century later, mass customisation has supplanted Ford's color approach, with the idea being that the more colors that are offered, the higher the profit. What is the significance for the factory? This section focuses on significant issue areas that changes in automotive production policy have brought about.

2.1 Color palette

Although paint coatings are crucial for safeguarding the body's surface, people typically notice them for their color. Color increases visual attraction, making it a crucial factor in purchasing decisions. PPG research indicates that approximately 60% of buyers cited color as a key consideration when purchasing a vehicle. Fig. 1 shows the proportion by color according to vehicle build data for the 2015 model year. Nearly 75% of cars in 2015 had paint jobs in the conservative hues of silver, gray, black, and white.

Fig. 1. 2015 Global Color Popularity – PPG data

The color palette has grown dramatically year over year. The range of colors and their characteristics is expanding as well. "Carmakers today have an endless variety of options," stated Jane E. Harrington, manager of PPG, "with a full spectrum of colors that can range in appearance from bright sparkle to silky pearlescence." This demonstrates that sellers are aware of these variations among possible customers. In response to the ongoing need for innovative color options in car coatings, PPG sent automakers 64 exterior hues to choose from when customizing vehicles for the 2018–2019 model year. The strategy and painting method are directly impacted by the pattern that has been noticed.

2.2. Painting process

Nowadays, painting is a multi-step, intricate, costly, energy-intensive procedure that has a negative impact on the environment.
Up to six layers of paint are used in automotive paint; these layers are applied individually but must cooperate to give color, durability, and corrosion protection. According to Geffen and Rothenberg (2000), each of these layers has unique performance criteria and needs to be ready in order to bind with the subsequent layer and create a strong covering that won't peel or flake.
Economic metrics show that painting is a significant production expense due to its high material usage and significant capital investments. The precise chemical composition, the color, and the method of application all affect the price of automobile paint ingredients (Geffen & Rothenberg, 2000).
The principal source of air emissions of controlled chemicals, such as volatile organic compounds (VOCs) and hazardous air pollutants (HAPs), is the painting process. The painting process also generates solid and hazardous waste, such as paint overspray waste, chemicals needed to clear paint lines, and application equipment trash (Geffen & Rothenberg, 2000).
Automotive paint quality, which is vital to product sales, is mostly determined by outside variables. Numerous factors, including substrate composition, temperature, humidity, air pressure, and air pressure, can affect color match, and many of these are outside the purview of contemporary facilities. The primary issue is that robots perform the painting process, necessitating the inclusion of both process and robot kinematics simulations in the simulation. Painting shop robots are typically employed in conjunction with line-tracking conveyors, which greatly complicates the task for simulation developers. For these reasons, research and development is still ongoing on painting process simulation techniques that would faithfully mimic the actual procedure.

2.3. Painting strategy

Reorganizing the painting process has become required due to the increasing number of colors available. Using an equal number of painting guns makes sense if there aren't many colors available. When the color palette is large, it becomes impossible to use this method because of factors like scarce resources and workspace, or expensive extra expenses. The most widely used remedy is the use of intricate painting systems, such as robotic cells. Although this type of technology becomes more flexible and efficient, robotic tools have to be modified every time the color shifts. The challenge of decreasing changeovers and associated expenses has arisen as a result of the painting strategy's advancement.

2.4. Production planning

At first, the entire automobile manufacturing process was a flow process, beginning at the press shop and continuing through the body and paint shops and ending at the assembly line (Fig. 2).
To guarantee a steady flow of supplies and finished goods, a production plan was established prior to the commencement of manufacturing. Sequencing was usually the last step of production planning; here, a build sequence was chosen so that the orders could be filled on a particular day (Epping, Hochstattler, & Oertel, 2004). This step was crucial because, since each order must go through multiple production stages and satisfy additional optimization requirements, sequencing has a significant impact on both production quality and prices. Parello, Kabat, and Wos were the first to explain this problem, which they named the Car Sequencing Problem (CSP) (1986). There is still a significant gap between the problem addressed in the literature and the actual industrial problem, even with the massive quantity of research on CSP conducted in recent years (Solnon, Cung, Nguyen, & Artigues, 2008). The rationale is that automotive variety changes occur far more frequently than once a day due to the steadily rising demand for specific car characteristics. Orders from customers are continuously fed into planning systems, allowing production schedules to be set for a maximum of three to four hours. This means that there isn't enough data to plan for an entire working shift. In reaction to the difficulties of long-term planning, the paint shop's organization has changed.

2.5. Paint shop structure

Over time, the configuration of the production line at the paint shop has undergone alterations. Significantly, buffers were present on the lines. Figure 3 displays a simplified representation of the updated paint shop's structure.

Fig. 2. Stages of car production.

Buffering is crucial for maintaining the uninterrupted flow of the industrial process. If there is a period when the paint shop is not operational because there is not enough paint, the vehicles are kept in a designated area until the paint shop is fully operational again. In addition, in the event of a malfunction in the body shop, vehicle bodies that are held in the buffer are continuously moved to an output line, thereby avoiding any interruptions in the painting process. Empirical evidence has demonstrated that this solution is superior in terms of efficiency and reliability compared to the flow system.
Buffer potential has also been utilized for an additional purpose - to facilitate the rearrangement of automobile bodies moved from the body shop to the paint shop, in order to minimize the frequency of painting gun changeovers.

An optimal approach would involve constructing a sufficiently extensive buffer where each line is exclusively allocated for a distinct hue (Fig. 4).
The size of the buffers is constrained by the available unused area. The buffer structure is the sole field that can be modified.

Fig. 4. Structure of ideal buffer with reserved line.

As a component of the project, three manufacturers located in Central Europe were visited.
Each of them utilizes buffers with distinct structures. This document provides a comprehensive description of how the organization of car flow is managed using the selected buffers.

The movement inside the blue columns is conducted vertically, but the transportation between buffering sites in the black columns is contingent upon the buffer structure.
The first buffer structure permits the movement of an automobile solely within a single row (Fig.5).

Fig. 5. Structure of exemplary buffer – type 1.

Fig. 6. Structure of exemplary buffer – type 2.

The second buffer structure (Fig. 6) includes a line with a reverse transport direction (green line), allowing automobiles from the last column of the other lines to be carried to the first position of this specific line.
The third buffer structure is equipped with a bypass mechanism, which is responsible for transferring any automobile body from the last column in the buffer to any location in the first column, thus reversing the sequence of bodies. This is seen in (Fig-7).

Fig. 7. Structure of exemplary buffer – type 3.

The architecture of the paint shop appears to be a highly efficient and effective solution that has undergone significant development over the years. Where is the primary issue located? The present systems used for managing buffers are inadequate.

2.6. Buffer control system in the paint shop

The buffer control system should address two issues that are closely linked to the purpose of a buffer. These objectives include the efficient management of uninterrupted traffic flow and the automated production of optimal sequences of cars.

To effectively avoid unexpected downtimes and interruptions that hinder productivity and incur substantial time and financial losses, one commonly employed approach is to eliminate the sequence optimization problem.
While visiting paint businesses, we witnessed various incorrect methods used to address the sequencing problem. The next paragraphs will explain the most crucial realizations of the control system. For the sake of safeguarding industrial data, the examples provided are designed to give a general overview of the situation without divulging specific information.
Factory A utilizes buffer type 2 and relies on operator expertise to determine when to load and unload the buffer.
In close proximity to the buffer, a workstation specifically built for the decision-making process was implemented (Fig. 8).

The buffer operator utilizes four monitors, each serving a distinct purpose:

• Monitor 1 shows a text file (such as MS Excel) that contains the production plan. It is updated approximately every 3-4 hours and shows the current production status.

• Monitor 2 displays the current state of the buffer using a SCADA application.

• Monitor 3 shows a QR code (previously known as VIN) that is read by a digital camera.

• Monitor 4 displays an operator panel.

The decision-making process occurs via multiple stages. Upon scanning the QR code, the operator receives information regarding the color that can be allocated to a body. The selection of one of the available colors is determined by comparing the information provided on monitors 1 and 2.
Next, a determination is made regarding the specific location within the buffer where an automobile will be guided. Meanwhile, the operator chooses one of the vehicles stored in the buffer for the painting process, aiming to achieve the longest sequences of cars with the same color. Numerical calculations and statistical analysis are only conducted by the operator.

Consequently, no sophisticated mathematical analysis is conducted. Furthermore, certain information, such as details about failures or paint flaws, is exclusively communicated verbally to the operator, without being recorded in the IT system. This information has a substantial influence on the process of making decisions.

Fig. 8. Exemplary workplace in real paint shop.

The primary issues related to the methodology employed in factory A can be succinctly outlined as follows:

• A workstation specifically designed for operators needs to be established.

• As a result of having 3 shifts, a minimum of 3 individuals must be hired.

• Manufacturing designers must provide a work environment that is both safe and conducive to good health for the operators.

• The operator's role can be characterized as demanding, repetitive, and monotonous, particularly when ergonomic considerations are disregarded.

• The effectiveness of sequencing relies more on intensive human effort rather than current technology.

• There is a lack of logical connections between the methods that individual operators utilize.

• The probability of the operator making an error is significant.

• The level of reliance on operator expertise is substantial. If an experienced operator is not available, there can be a substantial decrease in production.

The paint shop in plant B is organized with a buffer type 3 and utilizes automated car flow management. These systems rely on historical data and statistical analysis for their operation. The implemented program fails to consider the presence of unforeseen emergency scenarios. Consequently, if there is any malfunction, the buffer switches to manual control.
Every car is assigned a pre-established color prior to the commencement of manufacturing. Initially, specific colors are assigned fixed priority at the start of the decision-making process. Subsequently, the likelihood of selecting a particular color to paint a car is determined. Cars with the most probable color will be given the highest priority. This strategy is undeniably superior to the solution employed in factory A, although it still possesses numerous drawbacks:

• Although human work is partially reduced, some of the difficulties that existed in factory-A still persist.

• The system lacks flexibility as it only considers long-term trends and not short-term ones.

• Relying solely on past data renders it impracticable to adjust to fluctuations in the buffer status.

Factory C utilizes buffer type 1. The simple nature of the structure reduces the potential variations throughout construction sequences, hence complicating the decision-making process. Efforts have been made in recent years to address this issue without altering the buffer structure, however all these have been unsuccessful. Consequently, the buffer's potential is not completely harnessed, as its primary objective remains to guarantee uninterrupted production.
In summary, the increase in the color options available in response to market demands has led to a higher frequency of robot changeovers. Factories will experience an increase in the following indicators: paint loss, solvent use for cleaning painting guns, and environmental pollution. Consequently, the expenses of production are increasing. Hence, the automotive industry has been continuously endeavoring to minimize the frequency of color alterations within the enamel booth.
