Automatic Die-cutting Of Lithium Battery Electrodes
Summary of the equipment:
1.1. The equipment is suitable for automatic die-cutting of lithium battery electrodes.
1.2. Workflow:
The electrode coil material is controlled by the frequency conversion motor to be unwound, and sent to the die-cutting machine by the highland barley paper circulating conveyor belt driven by the servo motor through the tension floating roller and the precise deviation correction mechanism. After die-cutting, the edge collecting mechanism collects the edge material, and the electrode automatically flows into the material tray.
