[0002] With the rapid development of the new energy industry, batteries are widely used in new energy vehicles, energy storage, mobile electronic products, power tools and other fields. After the battery cells are assembled into modules, the modules need to be placed in a carrier and transported to different workstations through carrier tooling for testing and processing. In addition to the function of transporting modules, the carrier also plays a positioning role for the modules to ensure the consistency of the modules during the transportation process. The consistency of the module position in the carrier determines the processing quality of the module and the stability of the automation line. When the consistency of the module on the carrier is poor, it is easy to cause problems such as over-limit of the visual positioning station and poor welding consistency of the BSB welding station.

[0003] The existing auxiliary tooling mainly limits the module by the end limit block and the side limit block, and then locks the module by the spring pressure mechanism on the other side. When the movement of the tooling is blocked during the process of conveying the module, a large reverse impact force will cause the module to leave the end limit block, resulting in poor consistency of the module on the tooling, which affects the processing quality of the module. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content
