[0002] PACK assembly is a very important link in the battery manufacturing process, because not only do the battery cells, collection lines, module plugs, and components need to be assembled in the battery pack, but more importantly, the battery cells of different levels must be distinguished and unqualified battery cells must be retrieved to avoid subsequent repairs; the PACK works throughout the process when the battery cells are put into the shell. Once a problem occurs, it will affect the quality of subsequent work. The most obvious is the charging and discharging of the battery pack. If the battery cell is defective, the charge and discharge will be low, and the battery capacity cannot reach the ideal level. In the long run, it will affect the battery's efficiency and life. Therefore, it is very important to do a good job of PACK battery cell shell detection. At present, many shell detection devices detect one by one separately.

A detection component is also installed on the support frame, and the detection component includes multiple groups of probes 1 5 installed on the base plate 1 and multiple groups of probes 2 11 installed on the cover plate 10. The positive and negative poles of the battery cell 8 are connected to probes 1 5 and probes 2 11 respectively, and the detection results are transmitted to a display component for analyzing and displaying the results.

[0026] When the base plate 1 is larger than one group, such as the present embodiment including the first base plate 101 and the second base plate 102, the number of cover plates 10 is correspondingly the same as the number of base plates 1. Several groups of mounting holes 103 are provided on the base plate 1 and the cover plates 10. Adjacent base plates 1 and adjacent cover plates 10 are spliced ​​and connected to facilitate extending and shortening the length of the base plate 1.
