[0045] In some embodiments, a positioning sensor for detecting the placement position of the battery cell placement plate 210 is further included. Among them, the positioning sensor is a photoelectric sensor, and the photoelectric sensor is used to detect the position of the battery cell placement plate 210 to detect whether it is placed in place, prevent the battery cell placement plate 210 from shifting when placed on the positioning plate 110, and improve the welding accuracy.

[0046] During the use of the battery cell welding positioning mechanism, first, the distance of the positioning plate 110 is adjusted by rotating the adjusting screw. At this time, the pointer on the battery cell placement plate 210 moves on the scale 150, so as to determine the moving distance of the positioning plate 110. When the positioning plate 110 is adjusted to a suitable position, the positioning is completed by connecting the second positioning block 140 and the connecting block 230. The battery cell placement plate 210 is carried by moving the handle 211. The photoelectric sensor detects whether it is placed in place. The height of the battery cell is adjusted by the spacer 250.
