Semi-automatic Stacking Machine For Pouch Cell

tob technology

1 Equipment function description and technique process

1.1This Semi-Automatic Lithium Battery Stacking machine is used for the stacking of pouch cell. The working process is as follows: the separator is unwinding actively, and the separator is deflected, the ferry and the tension mechanism are introduced into the platform; the platform moves the diaphragm back and forth to reciprocate to place the pole piece; the suction cup is accurately positioned and stacked on the platform;

1.3 Equipment features
1) The platform adopts the sliding table structure, the cylinder moves, the positioning is accurate, and the stability is high;
2) The cathode and anode plates are designed separately to avoid mutual mixing of cathode and anode materials;
3) The separator is unwinding actively, the working tension is continuously adjustable, and the correcting device is provided;
4) The cathode and anode electrode carrying mechanisms are independently arranged and can be adjusted separately;
5) There are cathode and anode plate positioning devices, and the positioning plate is made according to the size of the electrode, and the adjustment is convenient;
6) The core is blanked by manual reclaiming;
7) The device interface is friendly, easy to operate and easy to maintain.
