The invention discloses an automatic pole ear bending device, which is characterized in that it includes a mounting seat, a through hole, a rotating cylinder, a pad, an air finger, a splint, a bump, a pressing block, a cover plate, a shaft, a top piece, a spine Claws, pole groups, side plates, mounting plates, cylinder bases, cylinders, pole lugs, partitions, pads are installed on the mounting bases, air fingers are installed on the pads, and the rotating cylinder is arranged below the mounting base. The front end of the finger is equipped with a splint up and down, and the front end of the splint is equipped with a clamp block and a cover plate. There is an pole group in the middle of the splint, and a mounting plate is provided above the pole group. The bottom of the cylinder is fixed with the mounting plate. One side of the cylinder Fixed on the cylinder seat, due to the addition of rotating top pieces, bumps and pressing blocks for synchronous pinching and bending of the tabs, the force of pinching and bending the tabs is consistent with the inclination, ensuring that the side plates of each pole group are not damaged, improving the Battery product quality and production efficiency.
