With the continuous development of the automobile industry, the lightweight of automobiles has become a hot spot in the market, and new materials, new processes and new structures in automobile manufacturing are constantly emerging. Laser processing technology has been brought into full play in automobile manufacturing. Today, Leapion Laser introduces the application of laser cleaning machine in automobile manufacturing industry.
1. During the automobile manufacturing process, the used drawing lubricants or cooling lubricants and anti-rust oils will contaminate the automobile components and seriously reduce the quality of the subsequent high-energy joining or bonding process, among which the welding seams and bonding in the powertrain components Strict quality standards have to be met, so the joint surfaces must be thoroughly cleaned.
Traditional cleaning methods are time-consuming, cannot be automated, and often have a detrimental impact on the environment.
2. In the automotive industry, before the body is overhauled, the old paint on the surface needs to be removed so that new paint can be applied.
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 reagents for paint removal. These methods have defects such as high cost, high energy consumption, easy pollution, and easy damage to the surface of the substrate.
3. The novel welding technology or connection process adopted in the continuous innovation of automobile technology requires perfect pretreatment of the surface of welding or connection, while traditional wet chemical cleaning or mechanical grinding treatment methods are often difficult to meet. ;
However, laser cleaning technology can just provide a dry and precise, non-abrasive cleaning process, and most parts are now laser cleaned.
Selective paint removal is one of the many applications of laser cleaning, using laser cleaning technology to thoroughly remove surface residues, resulting in strong, void- and micro-crack-free welds and bonds.
Typically, the top weathered coating on a vehicle needs to be completely removed before new paint is applied. Since the physical and chemical properties of the top layer of paint are different from the primer, the power and frequency of the laser can be set to remove only the top layer of paint.
Coating must be removed from critical welds on painted structural parts. Lasers can remove coatings without the need for hand or power tools, abrasives or chemicals. Laser cleaning technology is very effective.
The laser cleaning machine can be integrated with CNC machine tools or robots to implement remote control cleaning, which can realize the automation of equipment, form product line operations, and operate intelligently.
Laser cleaning is very gentle, and the short-term impact does not heat the metal surface and does not damage the substrate. And no chemical cleaning agent is needed, no cleaning waste liquid is generated, no pollution to the environment, and green environmental protection.
In addition to effective paint removal in the automotive industry, laser cleaning machines have many other applications, such as laser cleaning of tire abrasives, laser cleaning of carbon deposits, etc. For additional information and content inquiries about laser cleaners, please contact Leapion Laser.
