Automatic correction assembly of lithium ion battery code spraying device

The utility model discloses an automatic correction assembly of a lithium ion battery code spraying device, which comprises a frame body, four mounting plates are fixedly mounted on the outer side of the frame body, mounting bolts are in threaded connection with the interiors of the four mounting plates, backing rings are movably sleeved on the outer sides of the mounting bolts, springs are fixedly mounted on one sides of the backing rings, and the springs are fixedly mounted on the other sides of the backing rings. And a second screw rod group is arranged in the frame body. Through the arranged mounting plate, the mounting bolts are in butt joint with the corresponding mounting holes, then the mounting bolts are rotated, the mounting bolts extend out and extrude the springs under the action of threaded connection between the mounting bolts and the mounting plate, when the springs are extruded, acting force is applied to the inner sides of the mounting plate and the backing ring, and elastic force is opposite
