Semi-automatic Stacking Machine For Pouch Cell
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;
