[0002] When stacking battery cells to form modules, the centers of the battery cells are required to be located in the same plane as much as possible to reduce the gap during assembly of the battery cell modules and improve the energy density of the battery pack. The currently used double steel strip battery cell module is composed of a battery cell module end plate, a battery cell and a steel strip. The battery cell module end plates are respectively arranged at both ends of the length direction of the battery cell module, so that the two battery cell module end plates clamp the battery cell. By tying the steel strip to the battery cell module end plate, the clamping force of the battery cell module end plate on the battery cell is maintained to avoid positional displacement of the battery cell in the battery cell module.
[0003] However, the double steel belt module stacking tooling currently used adopts pins to fix the battery cell module end plates. Since the battery cell module end plates of the steel belt module are cast battery cell module end plates, the accuracy of the positioning holes is poor. The battery cell module end plates positioned by the pins have a large position offset, which will cause the battery cells to be misaligned during stacking. Moreover, the double steel belt module stacking tooling currently used must be set up separately, and the tooling can only adapt to the stacking operations of specific battery cell modules and is not compatible with other types of battery cell module stacking.
[0004] Therefore, there is an urgent need for a technical solution to solve the technical problems of the current double steel belt module stacking tooling, such as stacking position offset and incompatibility with other battery cell module stacking. Utility Model Content
