Battery cells in pouch design are picked from a conveyor belt and placed in a module carrier. The module assembly station combines the individual battery cells to form a battery sub-module. In order to compensate for the expansion which occurs during battery operation, the battery cells (pouch cells) are held centrally in the clamping frame by their fold. The cell is pre-centred by the electric parallel gripper and then gripped over a large area with the vacuum gripper. The sequence is insertion of clamping frame, insertion of pouch cell, insertion of clamp frame. The picture does not show the clamping of the clamping frame.
