Each carrier box on the shunted first and second main conveying belts can store two bare cells side by side, and a row of bare cells is moved at a time. Although the shunting of the conveying belt improves the work efficiency of the cell winding machine, there are still the following problems: the large area of the conveying belt in contact with the cells causes dirt on the surface of the cells, which greatly affects the plasma cleaning effect of the cells and thus affects the subsequent use performance of the cells. At the same time, the feeding method through the conveying belt has spatial limitations and needs to be improved. In view of this, we propose a 3C lithium battery cell high-precision feeding device.
