| 1. This machine is used for the die-cutting process of positive and negative electrodes of square lithium-ion batteries, and adopts automatic die-cutting and forming electrodes for lithium-sulfur batteries. 2. Manually install the pole piece coil on the air expansion shaft of the equipment, the equipment automatically unwinds, the correction mechanism automatically corrects the pole piece unwinding, and controls the tension of the pole piece through the tension control system. After the pole piece undergoes secondary correction, the feeding mechanism pulls the pole piece to the punching station, automatically die-cuts the pole ear, and then passes the CCD to detect the pole piece. The feeding mechanism continues to pull it to the cutting station. The CCD detection mechanism detects and distinguishes the size of the pole piece one by one. Defective products are automatically removed to the waste box, and qualified products are collected in the finished product box. When the box is full, it automatically flows into the conveyor line, and the empty box is automatically transported to the receiving station |
1. Use lithium-sulfur mold to form the pole piece, and make the mold size according to the process to avoid puncturing the diaphragm and short-circuiting the battery cell
