Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a battery clamping tool. Background Art

[0002] Currently, in the production and manufacturing process of square shell battery cells, the assembly of battery end caps plays a vital role as a key link in battery assembly. The battery end caps are not only an important part of the external structure of the battery, but also a key barrier to ensure that the internal components of the battery, such as battery cells, electrolytes and electrical connectors, are properly placed and protected. This step is usually carried out after the core processes such as the internal structure of the battery, including the stacking of battery cells, injection of electrolytes and arrangement of electrical connections, are completed. By accurately assembling the carefully designed end caps to the battery casing, the necessary limit can be effectively formed on the internal structure of the battery to prevent it from being displaced or damaged during subsequent use or transportation, while providing the necessary sealing performance to ensure the safety and stability of the battery.

[0003] Existing end cap assembly technology generally relies on welding, which involves permanently connecting the battery end cap to the battery casing through high-temperature melting. While welding technology provides strong connection strength and a good seal, it comes with the complex structure and cumbersome assembly and disassembly procedures of the welding clamping fixtures used during the end cap assembly process. The complex structure and cumbersome assembly and disassembly of existing battery clamping fixtures hinder maintenance efficiency, slowing down the entire battery production line and hindering battery production efficiency.
