Product Details

 Automatic Z-shaped Dual-Workstation Stacking Machine for Prismatic Lithium-ion Power Battery Cells


 

1. Equipment Introduction

1.1 Equipment Overview
This equipment is mainly used for the Z-shaped stacking process of prismatic lithium-ion power battery cells.

 

1.2 Workflow

The separator is actively unwound, fed through the tension control mechanism, and guided smoothly onto the stacking platform. This platform then moves back and forth to position the separator, setting the stage for electrode placement.

The stacking process starts with positive and negative electrode sheets: two robotic suction arms retrieve these sheets from their respective left-side feed boxes, precisely align them, and stack them onto the platform. Once stacking is complete, the separator is cut to length. A robotic arm then transfers the cell to the taping station, where taping is done automatically—all while the next cell begins stacking seamlessly, ensuring continuous operation.

 


1.3 Equipment Features

· 1.3.1 Separator: Active unwinding; tension control; deviation correction; static elimination; alignment accuracy ±0.5mm.

· 1.3.2 High precision: Mechanical positioning of electrode sheets ensures total stacking accuracy within ±0.3mm.

· 1.3.3 High efficiency: Single-side stacking speed reaches 1.2s–1.5s/Pcs depending on sheet size.

· 1.3.4 Dust protection: Effective dust protection mechanisms are installed at material box and pre-alignment positions.

· 1.3.5 Reliability: All high-precision and frequently moving modules are fixed with positioning pins.

· 1.3.6 Multi-sheet & missed sheet protection: Equipped with anti-multiple sheet mechanism and detection system to prevent stacking errors.

· 1.3.7 Tab inspection: Prevents inclusion of faulty electrode sheets with bent or missing tabs.

· 1.3.8 Stacked-cell discharge
