AI Technical Summary
During the cutting process of pouch cells, air leakage is likely to occur at the cutting end, and defective products are difficult to detect in the early stages, resulting in production waste and increased costs. In addition, a short circuit may form between the positive and negative electrodes during the cutting process, reducing the yield rate.
A servo-controlled precision sealing tab cutting machine is adopted. The precision sealing module performs secondary sealing on the cutting waste edges of the battery cell before cutting the tabs. The transfer module automatically turns the tabs to the cutting module, and the movable cutter achieves single cutting of one tab at a time, avoiding short circuits.
This effectively avoids air leakage after vacuum sealing, improves the yield rate, and ensures the continuity of the cutting process and product quality.
