[0003] However, with the rapid increase in the production of new energy vehicles, the traditional method of independent lifting table battery tray combined with manual tightening of bolts can no longer meet the high requirements of production cycle. This method is not only inefficient, but also prone to errors in manual operation, thus affecting assembly accuracy and vehicle performance.

[0004] In order to solve the above problems, an integrated battery pack assembly tooling structure came into being. The design of this tooling structure aims to improve assembly efficiency and accuracy. Through the integrated design, the positioning of the tooling and the vehicle body end is more accurate. Errors in manual operation are avoided. For example, a battery pack automatic installation system disclosed in CN115283976A includes a sling, an AGV, a transport trolley, a pallet, a synchronous lift and an assembly robot; the sling is used to lift the vehicle body to be assembled; the transport trolley is installed on the AGV, and the movement of the AGV drives the transport trolley to move; the pallet is used to place the battery pack to be assembled, and the battery pack to be assembled is placed on the transport trolley through the pallet and then transported, and a lifting mechanism is provided between the pallet and the transport trolley; the synchronous lift is used to lift the pallet, and the sling and the synchronous lift cooperate with each other; the assembly robot is used to install the battery pack and the vehicle body together. The battery pack automatic installation system realizes the automatic installation of the battery pack through the cooperation of the sling, AGV, the transport trolley, the pallet, the synchronous lift and the assembly robot, and the production efficiency is greatly improved. The technical solution disclosed in this patent document is a beneficial attempt in the relevant technical field. Utility Model Content
