Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to welding fixtures for acquisition boards. Background Technology

[0002] Currently, battery modules are widely used in various industries such as new energy vehicles and energy storage systems. Before assembly, battery modules require the individual cells to be connected in series and parallel according to the actual application, and then the corresponding battery brackets are designed and welded. The current conventional method is to visually inspect before welding, which is prone to omissions, resulting in reversed data acquisition line sequence in the welded battery module. The operation process is cumbersome, and the production cost is high and the cycle is long. Improved technologies, such as a new type of module data acquisition line welding fixture with application number 202420410203.7, use pressure blocks and fixing blocks to place the data acquisition line to be welded on the surface of the mounting platform and pass it through the middle of the fixing block. Then, the fixing plate is placed on the surface of the battery module and fixed to the surface of the mounting platform with bolts. At this time, the surfaces of the pressure block and the fixing block are in contact, which can limit the data acquisition line. However, this fixing method is cumbersome and costly.
