Equipment Overview

1. This machine is used for the die-cutting process of positive and negative electrodes of square lithium-ion batteries. It uses hardware molds to automatically punch and form electrodes.

2. Manually install the electrode coil on the air expansion shaft of the equipment, the equipment automatically unwinds, and the correction mechanism automatically corrects the unwinding of the electrode, and controls the tension of the electrode through the tension control system. After the electrode is corrected twice, the feeding mechanism pulls the electrode to the punching station, and the hardware mold automatically forms the pole ear. The CCD detects the appearance of the front and back of the electrode. The feeding mechanism continues to pull to the cutting station, and the cutting mold automatically cuts the electrode and forms the fillet. The electrode is sent to the vacuum conveyor belt, and the upper and lower surfaces of the electrode are dusted. The CCD detection mechanism detects and distinguishes the size of the electrode 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 is manually taken out.

Equipment features

1. The pole piece is formed by a mold

2. The unwinding mechanism can realize manual and fast roll change to improve efficiency

3. The pole piece is adjusted by the unwinding correction and process correction system before die cutting to effectively ensure the accuracy of pole piece forming

4. The materials of the punch and die are imported tungsten steel, processed by JG coordinate grinder, the mold has high precision and good finish, and the burr on the edge of the pole piece is small and not easy to fall off

5. The punch is evenly distributed with pressure plates around it, and it is guided by many precision guide pillars to effectively control the powder falling on the edge of the pole piece cut.

6. Material box collection, manual unloading
