1. Equipment Description:
This device is used for producing cylindrical lithium-ion battery cells and is one of the key equipment in battery manufacturing. The process flow is as follows: the cathode and anode sheets prepared by the slitting machine, as well as the diaphragm, are actively unfolded, subjected to tension control, dust removal, coil guidance, ironing, diaphragm anti-static, quality inspection, and sent to the winding section through the guide roller and electrode feeding mechanism. After winding is completed, the battery is removed by the robotic arm, subjected to short circuit detection, counted by a photoelectric counter, and transported to the collection platform through a conveyor belt. If defective cells are detected during the processing, they will be rejected and sent to the defect collection box.
