Description

Technical Field

[0001] This utility model relates to the field of battery module welding technology, specifically a tooling for welding battery modules. Background Technology

[0002] With the continuous increase in market demand for power batteries, higher requirements have been placed on the performance, process and production efficiency of lithium batteries, and square batteries currently occupy a very important position in power batteries.

[0003] In existing spot welding technologies for PACK battery packs, welding fixtures typically include a main body, a base plate, and a cover plate. The main body has a positioning groove to accommodate the battery, and the cover plate has a nickel sheet guide groove. Positioning posts are used to fix the cover plate. However, when placing the product into the main body, it is usually necessary to close one side of the cover plate, place the fixture on its side to place the battery into the fixture, and then close the other side of the cover plate. After welding, both cover plates need to be removed simultaneously before the product can be taken out, which is inconvenient and cumbersome. The product is prone to inaccurate fixation and displacement when placed, which can lead to misalignment when closing the cover plate and damage to the outer film of the product. Furthermore, the positioning post fixing method can cause product misalignment and welding defects after welding, which can easily lead to product quality risks. Therefore, we need a tooling for welding battery modules. Utility Model Content

[0011] Compared with the prior art, this utility model provides a tooling for welding battery modules, which has the following advantages:

[0012] 1. The battery module welding fixture, with its cover plate A and cover plate B, allows both sides of the lower mold body to be opened simultaneously, facilitating the quick placement and removal of battery modules on the lower mold body, thereby improving the stability of product welding quality and increasing work efficiency.

[0013] 2. The battery module welding fixture has a foolproof notch on the upper mold body to prevent the battery module from being placed in the wrong direction. At the same time, the direction scale can be set to guide the product when it is placed in the welding equipment to prevent positional deviations that may affect the welding quality of the product.
