The battery stacking machine is one of the key equipment for the production of lithium polymer batteries. The working principle of the semi-auto stacking machine: the positive and negative electrode are loaded into the material box, the machine moves to the left and right, and the pole pieces are picked up in the positive and negative material boxes. After the secondary positioning, the positive and negative electrode pieces are alternately placed on the lamination table.The diaphragm is unwinding actively, and the diaphragm to reciprocate left and right to form a "Z-type " winding.
