AI Technical Summary
Traditional mechanical stamping processes suffer from burrs and collapsed edges, while pure laser cutting is inefficient and the heat-affected zone can easily cause the electrode coating to peel off. Existing molds cannot adapt to the dynamic processing requirements of lasers, affecting the forming accuracy of the electrode tabs and the performance of the battery.
A V-angle cutting device for electrode sheets was designed, which combines laser cutting and die stamping. The forming angle of the electrode tab is precisely controlled by the V-angle die. Components such as threaded strips, guide plates, fans, cleaning plates, and laser cutting heads are used to achieve synchronous operation, thereby improving processing accuracy and efficiency.
It achieves precise control of the tab forming angle, reduces internal resistance fluctuations, extends battery cycle life, increases equipment capacity, reduces laser power loss, and cleans up materials during cutting, thereby improving production efficiency.
