Solid-State Battery Stacking Machine

· Product Description

This machine realizes automatic Z-stacking, taping and discharging of lithium-ion battery cells. The separator is actively unwound
with a deviation correction mechanism to maintain stable and consistent tension, and delivered to the main stacking platform via a
constant tension system. Positive and negative electrodes are supplied by single-station vacuum suction. The system features automatic
material shortage detection and alarm, and effectively prevents double-sheet feeding. Robots pick electrodes from material boxes
respectively. After pre-positioning, electrodes are accurately stacked on the main platform. When reaching the preset number of layers,
stacking stops. The separator is cut by hot cutting, followed by automatic taping. Finally, the finished cell is transferred to the unloading
platform by robot for manual collection.
