Pneumatic grippers are mainly used in the prior art to achieve the relative position change of single or double cells. However, when multiple cells need to be flipped and positioned at the same time, the pneumatic grippers are relatively cumbersome to operate, and the simultaneous flipping and positioning of multiple cells cannot be achieved, resulting in low cell flipping efficiency.
