HOME >> PRODUCTS >> Lithium Battery Assembly Machine >> Pouch Cell Stacking Machine
The separator is actively unwound, guided onto the stacking platform via a tension mechanism, and moved back and forth by the platform to position the electrodes. Two robotic arms with suction cups separately retrieve positive and negative electrodes from the two left-side feed hoppers, then stack them onto the platform after precise positioning. Upon stacking completion, the separator is cut, and a robotic arm transfers the cell to the adhesive tape station for automatic taping. The next cell then starts automatic stacking. (No tail turning).
