[0018] The battery in the previous process is transported to the front side of the folding device 5. The skirt droops slightly under the action of weight. The Y-axis drive device 1 first drives the installation box 4 to move forward so that the skirt corresponds to the upper folding knife 52 and the lower folding knife 53.
