[0044] A method for using a multi-station coordinated battery core assembly device comprises the following steps:

[0045] Step 1: Run the working motor 107 to make the conveyor belt 103 drive the battery cell assembly rack to move intermittently, then work the motor 207, and with the cooperation of the U-shaped plate 204, the slide plate 209, the support plate 216, and the battery pick-and-place clamp body 220, the short plate 219 drives the battery cell to rotate and move it to the battery cell assembly rack, thereby completing the stacking of the battery cell group;

[0048] Working principle: When the present invention is used, first place the placement rack at the center of one side of the mounting rack 2 301, then place the battery cell assembly rack on the conveyor belt 103, and then operate the motor 107, so that the fixedly connected fixed dial 106 rotates, and then under the action of the matched fixed groove wheel 105, the conveyor belt 103 works intermittently, and wait for the battery cell assembly rack to move to one side below the U-shaped plate 204, and then operate the motor 207, so that the first gear 206 drives the second gear 215 to rotate, at this time, the fixedly connected short shaft 214 will drive the two rotating blocks 212 to rotate, and then the connecting shaft 213 and the inclined groove 210 and the side groove 208 are rotated. With the cooperation, the two slide plates 209 can drive the support plate 216 to move back and forth in an alternating manner. When one of the battery pick-up and placement clamp bodies 220 moves to the top of the placement box 202, the telescopic shaft 1 218 can be operated, thereby causing the fixedly connected battery pick-up and placement clamp body 220 to move downward, thereby achieving the effect of clamping the battery cells inside the placement box 202, and then the motor 207 is operated again to cause the short plate 219 clamping the battery cells to move to the top of the battery cell assembly rack, and then the motor 1 217 is operated, so that the short plate 219 drives the battery cells to rotate and move them to the battery cell assembly rack.

[0050] When the spot welding head body 321 is working, by running the suction fan 322, and then with the cooperation of multiple suction heads 319, the smoke generated by spot welding can be transported to the air outlet pipe 323 through the suction head 319 and discharged, preventing the spot welding work from being affected by excessive smoke, thereby solving the problem that a large amount of smoke will be generated when spot welding the battery cell, and the smoke generated by welding will have an adverse effect on the spot welding work.
