[0002] New energy vehicles gradually occupy a large share of the automobile market, including pure electric vehicles, plug-in hybrid vehicles and range extended vehicles, and new energy vehicles gradually become popular in the automobile market, but although there are many types, they cannot be separated from the support of power storage technology. A common energy storage method is a battery pack, which can be quickly charged by a charging power of about 100KW. Ternary lithium batteries and iron phosphate lithium batteries should be relatively widespread. However, different automobile manufacturers adopt different schemes for the frame scheme integrated into the battery pack. A more common scheme is to combine multiple small batteries in series and parallel, and to be equipped with a special electric control PCBA, so that the integrated battery pack charging and discharging power is controllable and reliable.

[0003] A battery pack adopts multiple battery series connection, and is assisted by a PCBA to implement charging and discharging control. Under the background of the production capacity demand of batch battery pack production, the battery module filled into the battery box needs to be assembled and welded with the PCBA, including battery module feeding, PCBA feeding, positioning attitude determination and screw assembly. Therefore, it is necessary to design a complete set of automatic equipment to complete the connection of various processes, improve the assembly efficiency and maintain the unified quality control.
