Subsequently, the center clamping cylinder 623 drives the two positioning jaws 624, which, through the clamping connecting block 625 and the clamping guide rod 627, drive the two center clamping push blocks 628 to clamp the two sides of the phone box, thereby achieving center positioning of the phone box.

The film-tearing gripper 35 has an L-shaped structure. Its L-shaped vertical end is connected to the output end of the film-tearing clamping cylinder 34, and the clamping part 36 of the L-shaped horizontal end is inclined upward, which is conducive to better grasping the edge of the film during the film-tearing process, making it easier to be torn off, and improving the thoroughness and flatness of the film tearing.
