Lithium-ion batteries, as a new type of energy storage power source, have the advantages of high energy, high operating voltage, small size, and long storage life. As contemporary people have higher and higher requirements for energy and the environment, power lithium batteries cause less damage to the human body and the environment during the production process, and have great advantages over traditional lead-acid batteries. As environmental problems caused by automobile exhaust emissions intensify, power lithium batteries can also replace fuel and become a new energy source for automobiles.

In the 46 large cylindrical Pack assembly process, it is inevitable to use liquid cooling belts to insert between the battery cells to cool the module battery cells. The traditional process is as follows: 1. After placing the module box, install the glue-coated liquid cooling belt in the module box; 2. Take the battery cell and insert it diagonally from the side to assemble it on both sides of the liquid cooling belt; 3. Repeat step 2 until the water cooling belt and battery cells in the module box are fully assembled;

[0004] During this assembly process, plugging and unplugging the battery cells causes the colloid coated on the liquid cooling belt to flow down, resulting in glue loss and poor heating effect of the liquid cooling belt; secondly, how to ensure the gap between the liquid cooling belt and the 46 battery cells during the assembly process is also a problem. There are also problems such as manual work is difficult and inefficient. Utility Model Content
