AI Technical Summary
Technical Problem
During the laser welding process of aluminum battery covers, the high temperature generated at the welding point causes a decrease in the sealing performance of the sealing ring.
Method used
A laser welding auxiliary device for battery casing was designed, including a pressure plate, a heat dissipation groove, a cooling sleeve, and a crossbeam structure. The heat dissipation groove accelerates cooling, and the cooperation between the crossbeam and the slide ensures good contact between the cooling sleeve and the battery cover, reducing heat conduction to the sealing ring.
Benefits of technology
It effectively reduces the temperature of the sealing ring, prevents a decrease in sealing performance, and improves the cooling efficiency during the welding process.
