3 Applications Of Laser Cleaning Machine in Battery Cleaning

In recent years, the rapid improvement of new energy vehicles has promoted the rapid development of the new energy industry. In the rapid development of new energy vehicles, higher, newer and more stringent requirements have been continuously put forward. The cleaning of new energy vehicle parts is a new process that has been spawned to adapt to new application requirements. It must be continuously improved to adapt to the new market environment.

In the field of new energy, the requirements for laser cleaning are more precise. Nowadays, laser cleaning has been widely used in the three power battery production processes of pole piece manufacturing, battery cell manufacturing and battery assembly.

When welding power batteries, it is necessary to ensure the overall structural strength. At this time, it is necessary to clean up the leakage and oxide layer residue near the injection hole. Through the precise treatment of laser cleaning, the influence of leakage and oxide layer can be reduced to a considerable extent without affecting the battery structure.

In pole piece manufacturing, the coating and dirt near the pole ear need to be cleaned first to ensure the stability of the current collector. The pole piece material is relatively fragile. Mechanical or chemical cleaning will affect the pole piece structure, and it is difficult to ensure the effect of coating cleaning. The use of laser cleaning can increase the battery energy density, maintain battery stability, and optimize the overall charge and discharge performance.

In battery assembly, the battery tray welds, battery cover electrophoretic paint, protective bottom plate, etc. also need to be cleaned. Using laser to clean these structures can reduce environmental pollution on the one hand, and protect the circuit and prevent power battery quality problems on the other.
