Double Working Station Auto Stacking Machine

Ⅰ、Equipment Introduction：

1.1 Equipment overview

This equipment is mainly used for Z-shaped stacking of  lithium-ion power battery cells.

1.2 Workflow

The separator is actively unwinded and introduced into the stacking table through the tension mechanism; The sacking table drives the separator  to move back and forth to place the electrode The positive/negative electrodes are stacked first, and the two sets of manipulator suction cups take the positive and negative plates out of the two boxes on the left, and stack them on the stacking table after accurate positioning; After the stacking is completed, the stacks is transferred to the tail roll gluing station by the manipulator, the  separator is cut off, and the gluing is automatically applied; At the same time, the automatic stacking of the next cell is started.

1.3 Equipment features

1.3.1 Separator: active unwinding; separator deviation correction; separator alignment accuracy ± 0.3mm;

 1.3.6 Multi-piece leakage protection: leakage detection protection;

Multi-plate prevention mechanism; Multi-chip detection mechanism can effectively prevent multiple pieces

from overlapping into the core.

 1.3.8 Stacking and blanking of cell(single blanking can be performed by manipulator)
