HOME >> PRODUCTS >> Lithium Battery Assembly Machine >> Pouch Cell Stacking Machine
The separator is actively unwound, fed into the stacking platform via a tension mechanism, and then driven by the platform to move back and forth for electrode sheet positioning. Two robotic arms with suction pads separately pick up positive and negative electrodes from two left-side feed hoppers, precisely position them, and stack them onto the platform. After stacking, tail wrapping is automatically carried out (with a switchable non-tail-wrap mode), by separator cutting. A robotic arm transfers the stacked cell to the taping station for automatic taping, while the machine simultaneously initiates the stacking of the next cell.
