Description

Technical Field

[0001] The utility model relates to the technical field of battery core pressure maintenance, in particular to a pressure maintenance tool and a battery core pressure maintenance system. Background Art

[0002] After the battery cell module is placed in the box, the module needs to be pressurized. In the existing pressure-maintaining equipment, the hanger assembly and the pressure-maintaining assembly are set together, which makes the entire equipment occupy a large space and the equipment manufacturing cost is relatively high.

[0003] The duration of module pressure holding is usually long. This process requires continuous pressing of the pressure holding equipment. When there are a large number of modules that need to be pressure held, the high cost of the pressure holding equipment will limit the number of modules that can be pressure held at the same time, affecting production efficiency.

[0004] The large space occupied by the assembly equipment means that when one module is put into the box and pressure-maintained, the adjacent module cannot be put into the box and pressure-maintained. The next module can only be put into the box and pressure-maintained after the glue of the previous module has dried and the assembly equipment has been removed, which greatly prolongs the production time. Utility Model Content

[0005] The utility model aims to provide a pressure-maintaining tool and a battery cell pressure-maintaining system to solve the problems of large space occupied and high manufacturing cost of the collection equipment in the prior art.

[0011] As a preferred solution of the utility model, a linear bearing is provided on the base, and the connecting shaft passes through the linear bearing.

[0020] Arranging them on different sides facilitates the installation of the driving device and can shorten the distance between the pressure-maintaining plate and the base, thereby helping to reduce the space occupied by the pressure-maintaining tooling.

[0021] As a preferred solution of the utility model, a side of the base facing away from the pressure-maintaining plate is provided with a hanging ring, the number of the hanging rings is 4, and all the hanging rings are distributed in a matrix.

[0022] The lifting ring is provided to facilitate the lifting and transportation of the pressure-maintaining tooling, making the installation and disassembly of the pressure-maintaining tooling more convenient.
