Compared with traditional manual insertion, the accuracy rate of forward and reverse pairing is as high as 99.9%. All handling and insertion operations are performed on batteries in groups, and the speed is also increased to about 3,000 batteries per hour.

[0021] Specifically, the battery transport mechanism 1 adopts a servo module.

[0022] In the present invention, a servo module is used to transport batteries, which effectively improves the transport efficiency and reduces the labor intensity of workers.

[0023] Specifically, the forward and reverse assembly mechanism 2 includes a first lead screw 21 , a clamp 22 disposed on the first lead screw 21 , and a first cylinder 23 , wherein a magnet is disposed on the clamp 22 .

[0024] In the present invention, the first lead screw 21 and the first cylinder 23 work together, are configured in positive and negative directions in the order of series and parallel, are combined into a group of correctly matched battery packs through the first cylinder 23, and are transported to the grasping station of the three-axis robot 3; at the same time, a magnet is provided on the clamp 22 to assist in clamping the battery, thereby ensuring stability and reliability during the clamping process.

[0026] In the present invention, the grouped clamping pieces can be used to grab more than 10 batteries at a time. In actual use, the grouped clamping pieces can also be designed according to actual needs to grab more batteries at a time.

[0027] Specifically, the base loading and positioning mechanism 4 is a parallel double-row structure, and the base loading and positioning mechanism 4 is driven by a second lead screw 41 .
