The automobile manufacturing industry is an industry where new technologies are very concentrated. Today's automobiles not only require practicality, but also economy and beauty. The update speed is accelerating day by day. Traditional cleaning methods are inefficient and low-precision, making it difficult to meet the needs of fine cleaning and low-cost processing in modern automobile manufacturing.

　　In the automotive manufacturing process, the use of drawing or cooling lubricants and anti-rust oils can contaminate automotive components, seriously reducing the quality of subsequent high-energy bonding or bonding processes, where welds and bonding in powertrain components must meet strict Quality Standards, therefore, the joint surface must be thoroughly cleaned. Traditional cleaning methods are very time-consuming, cannot be automated, and often have a harmful impact on the environment. The use of laser cleaning's fast, automated features allows for thorough cleaning of surface residues, resulting in strong, voids-free and micro-crack-free welding and bonding. In addition, laser cleaning is gentle and the process speed is obviously faster than other methods, these advantages have been recognized by the automotive industry.

　　In the automotive industry, before the car body is overhauled, the old paint on the surface needs to be removed in order to spray new paint. There are many traditional car body paint cleaning methods, mainly mechanical and chemical methods, among which mechanical methods include high-pressure water jet paint removal, sandblasting and steel brush grinding, and chemical methods mainly refer to chemical reagent paint removal. These methods have defects such as high cost, high energy consumption, easy pollution, and easy damage to the surface of the substrate, which have gradually failed to meet the high requirements of modern cleaning methods for environmental protection. In response to this situation, many new cleaning technologies have emerged, and laser cleaning, as one of the important means, has gradually shown its superiority. Selective removal, no substrate damage, and fast cleaning rate are the key favorable factors for laser cleaning paints.

　　Laser cleaning equipment can not only perform surface rust removal, paint removal, oxidation layer removal, oil removal, etc. on various parts of the car (car wheels, brake pads, hood, engine, etc.), but also has powerful functions. Laser cleaning can be used stably for a long time, with low operating costs, low maintenance rates, and no other consumables. It can also save a certain amount of labor costs for enterprises, low operating costs, and more importantly, it can easily realize automated operation.
