Problems solved by technology

[0004] On the one hand, the stacking table can only pick up one pole piece at a time between the positive and negative poles. The long loading time leads to slow lamination speed. The lamination speed is about 50p / m, and the work efficiency is low. Second, the whole machine The structure is complex, and the stacking table moves back and forth between the positive and negative electrodes and the operation is unstable, resulting in poor lamination effect
