As the core component of a battery, the production efficiency of the battery cell directly determines the overall battery production efficiency. In the packaging production of battery cells, due to their relatively small size, the picking and placing modules and transfer modules on each material handling mechanism operate very frequently. In order to control packaging costs, there are many production and packaging processes, resulting in a long production line and requiring a large production space. In particular, the packaging process, with its blister packs, battery cells, and cardboard boxes, occupies a significant amount of space and requires manual assistance for material handling, leading to high production costs.
