The battery pack is composed of battery modules. For example, different products such as blade batteries, cylindrical batteries, and square batteries are arranged in a modular combination in a Pack box.

[0003] In the existing process of loading a battery module into a box or a cabinet, a robot gripper is used to complete the operation. The gripper directly applies an external force to the battery module for clamping. After transporting it to the corresponding position, the structure on the gripper is used to push the battery module to achieve box loading.

[0004] However, it is very difficult for the existing battery grippers to perform the operation of loading the battery into the box in a limited space. If the gripper is made large enough to meet the requirement of the stability of clamping the battery, it is difficult to load the box due to its large size. If the size of the gripper is made small, there will be problems such as unstable clamping of the battery, resulting in the battery falling off, or there is a large clamping force between the gripper and the battery, thus increasing the friction force between the battery and the gripper, and the friction force will cause wear to the battery module.

After the battery module is stably clamped by the two clamping jaws 2, the six-axis robot connected to the installation cross beam 1 drives the two clamping jaws 2 to put the battery module into the PACK box body.

[0028] In the above structure, the cross section of the clamping finger 24 is a right trapezoid, and the large-end bottom edge of the clamping finger 24 is connected to the special-shaped clamping jaw body 23. The bottom support rib 27 is arranged at one end of the small end of the clamping finger 24.
