[0002] The battery pack is a kind of energy source used for power supply, which is mainly assembled by battery pack, bottom shell, top shell and circuit PC board. With the development of science and technology, battery packs are widely used in electronic equipment and new energy vehicles, and are power energy components. The battery pack needs to be screwed during the production process. At this time, the battery pack is provided with a screwing position, and the screws are tightened under the action of a screw gun.

[0003] Currently, in the back-end of the power battery pack line, the battery module needs to be fixed in the frame by screwing it on the top and bottom of the frame. When the screws on the bottom of the battery module need to be tightened, the battery pack (sub-pack) weighing approximately 50 kilograms needs to be turned over, with the bottom end of the battery module facing up to complete the screw tightening process. After tightening the screws, the sub-pack is returned to its original position. This entire process requires the heavy battery module to be turned back and forth, which wastes a lot of manpower and poses safety risks. Utility Model Content

The locking nozzle 310 is connected to the screw supply system and the negative pressure air source through the air pipe. After the initial positions of the locking modules 3 on both sides are corrected, the screws are adsorbed into the locking nozzle 310 through the external negative pressure air source, and the cylinder 32 drives the servo electric tightening gun 38 to feed automatically. The head end of the locking rod 39 is extended into the locking nozzle 310 until it supports the screw, and at the same time drives the locking rod 39 to rotate to lock the screw to the product, so as to facilitate the simultaneous completion of the screw locking process on the top and bottom of the battery pack.
