200-Type Automatic Double-Workstation Stacking System for Prismatic Battery Cell Assembly
1. Equipment Introduction
1.1 Equipment Overview
This equipment is mainly used for Z-shaped stacking of prismatic lithium-ion power battery cells.
1.2 Working Process
The separator is actively unwound, guided through a tension mechanism, and introduced into the stacking platform. The stacking table drives the separator to move back and forth to place the electrodes. The positive and negative electrodes are stacked first; two sets of mechanical arms with suction cups respectively pick up the positive and negative electrodes from the two material boxes on the left. After precise positioning, they are stacked onto the stacking platform. After stacking is completed, the cell is transferred to the tail tape station via mechanical arm, the separator is cut, and tape is applied automatically. The next cell stacking process starts simultaneously.

1.3 Equipment Features
1.3.1 Separator: Active unwinding; alignment correction; alignment accuracy ±0.3mm.
1.3.2 High precision: Through mechanical positioning of the electrodes, stacking accuracy within ±0.3mm is guaranteed.
1.3.3 High efficiency: Overall stacking speed reaches 0.5s–0.8s per piece.
1.3.4 Dust protection: Effective dustproof mechanism installed on material box and pre-positioning station.
1.3.5 Reliability: Positioning pins are installed on high-precision and frequently moving modules.
1.3.6 Multi-sheet & missed sheet protection: Detection and prevention mechanisms avoid multiple or missed sheet stacking.
1.3.7 Tab corner defect detection: Prevents misalignment and defective tab insertion.
1.3.8 Cell stacking discharge (able robotic single cell discharge).
