Figure 4 , 6 As shown in , 7, a welding fixture frame 5 is installed on the driving slide 4, a fixed block 24 and a slider guide rail 27 are installed at one end of the welding fixture frame 5, the fixed welding pressure head 13 is connected to the fixed block 24 through an equal height screw 29, and the sliding welding pressure head 14 is connected to the slider 23 through the equal height screw 29. A welding pressure head offset cylinder 15 is installed on the welding fixture frame 5 in parallel with the screw guide rail 2, and the welding pressure head offset cylinder 15 is connected to the sliding welding pressure head 14. A rectangular spring 26 is mounted on the equal height screw 29, and the rectangular spring 26 is used to ensure that the clamping force of the welding pressure head on the bar is constant at 300N. Four sets of equal height screws 29 and rectangular springs 26 are respectively arranged between the sliding welding pressure head 14 and the slider 23 and between the fixed welding pressure head 13 and the fixed block 24 to ensure uniform distribution of force. The equal height screws control the single pressure head to be in a vertical state when pressing the pole. A first slide cylinder 16 is longitudinally installed in the welding fixture frame 5 , a second slide cylinder 17 is longitudinally installed in the first slide cylinder 16 , and a laser displacement sensor 18 is installed on the second slide cylinder 17 .
[0024] like Figure 7As shown, the fixed welding ram 13 and the sliding welding ram 14 are provided with a gas storage port 28 and an air outlet 30, the gas storage port 28 is connected to the air outlet 30, and the gas storage port 28 is connected to the external nitrogen gas storage tank through the protective gas joint 25, so as to blow out the nitrogen protective gas during welding. When the nitrogen enters from the protective gas joint 25, the gas storage port 28 buffers the nitrogen so that the nitrogen reaches a stable state when it is blown out, and the air outlet is tilted to blow directly at the welding point to ensure that the nitrogen concentration at the welding point is close to saturation. The dust removal pipeline 19 is installed on the welding fixture frame 5, and the dust removal pipeline 19 is used to clean the welding slag after welding.
[0025] like Figure 5 As shown, a cleaning bracket 6 is installed on the frame body 1 at the end of the upper screw guide rail 2, a brush lifting slide 7 is longitudinally installed on the cleaning bracket 6, a brush moving cylinder 31 is installed on the brush lifting slide 7 parallel to the driving slide 4, a cleaning support 32 is installed on the brush moving cylinder 31, a rotating motor 20 is installed on the cleaning support 32, and the rotating motor 20 is connected to the cleaning brush 21 through a coupling 22.

The wind knife 11 prevents the rebound welding slag from damaging the galvanometer during welding.
[0027] Working principle: The battery module moves on the production line. After reaching the designated position, it is lifted up by the lifting mechanism on the production line. Then, the two driving slides 4 move relatively through two sets of lead screw guide rails 2. After reaching the position corresponding to the blade battery of the battery module, the first slide cylinder 16 and the second slide cylinder 17 respectively drive the laser displacement sensor 18 to two different heights to measure the distance of the single pole of the blade battery twice. Then, the sliding welding pressure head 14 is driven to move by the welding pressure head offset cylinder 15 to ensure that the welding pressure head extends into the clamping position of the bar. At this time, the welding pressure head offset cylinder 15 adjusts the welding pressure head to the center position of the pole. Then, the slide 4 drives the welding fixture 5 to move toward the blade battery, so that the sliding welding pressure head 14 and the fixed welding pressure head 13 can clamp the battery bar. The robot 9 controls the movement of the laser galvanometer mechanism 10 and the camera 12. The camera 12 shoots the mark point to determine the position of the battery module. The laser emitted by the laser galvanometer mechanism 10 passes through the gap between the sliding welding pressure head 14 and the fixed welding pressure head 13 to reach the battery bar, realizing the welding action. After the welding of the current battery bar is completed, the laser galvanometer mechanism 10 moves to the next group of battery bar for welding, and at the same time, the current sliding welding pressure head 14 and the fixed welding pressure head 13 move to the next group of blade batteries for pressing, and so on, until the bars of all blade batteries in the current battery module are welded, and then the equipment is reset, the lifting mechanism on the production line is lowered, and the product flows out of the station. After the welding is completed, the driving slide 4 and the brush moving cylinder 31 drive the welding fixture frame 5 and the cleaning brush 21 to move in opposite directions respectively, and then the brush lifting slide 7 drives the brush moving cylinder 31 to descend, and then the welding fixture frame 5 and the cleaning brush 21 move relatively, and the cleaning brush 21 reaches between the sliding welding pressure head 14 and the fixed welding pressure head 13, and the brush moving cylinder 31 drives the cleaning brush 21 to rotate to clean the welding pressure head.
