Subsequently, the incomplete gear 272 disengages from the first connecting gear 263 and transmits the second connecting gear 295. The second connecting gear 295 drives the transmission roller 292 to transmit the transmission belt 293 to roll, thereby driving multiple tooth blocks 294 to move. Subsequently, the incomplete gear 272 disengages from the second connecting gear 295 again to transmit the first connecting gear 263, so that the welding gun 250 welds the next battery again. Repeating the above operation can complete the welding of a row of batteries. S3, rectangular welding steps: After a row of batteries is welded, when the incomplete gear 272 transmits the second connecting gear 295, the multiple tooth blocks 294 will transmit the pinion 283, and the pinion 283 drives the bidirectional screw 281 to rotate. The rotation of the bidirectional screw 281 drives the two U-shaped blocks 282 to approach each other. The push-pull rod 285 then pushes the long plate 284 to drive the moving slide 140 to move, so that another row of batteries moves to the bottom of the welding gun 250. Subsequently, the incomplete gear 272 reciprocates the first connecting gear 263 and the second connecting gear 295 again to complete the connection between the rectangularly arranged batteries and the nickel sheets.

[0030] The implementation principle of the embodiment of the present invention is as follows: when in use, the battery pack to be welded is placed on the top of the movable slide 140 and below the pressing plate 153, and then the nickel sheet is placed on the top of the battery pack, and the threaded rod 154 is rotated and adjusted, and the threaded rod 154 is adjusted to drive the pressing plate 153 to descend to press and fix the battery pack and the nickel sheet. After the fixation is completed, the motor 271 is turned on to drive the incomplete gear 272, and the incomplete gear 272 will first drive the first connecting gear 263 to rotate one circle, and the first connecting gear 263 will drive the rotating rod 261 and the rotating disk 262 to rotate one circle, and the rotating disk 262 will drive the hollow block 210 and the welding gun 250 to perform a round of lifting operation through the connecting arm 264. When the hollow block 210 descends, , the lifting spring 2414 lifts the movable rack 2412 through the top plate 2413, so that the movable rack 2412 drives the hollow gear 246, and the movable ratchet 244 and the fixed ratchet 243 limit the internal wheel 245 to rotate in one direction, so that the hollow gear 246 idles on the outer surface of the internal wheel 245 and pushes the bevel block 248 to move through the same direction ratchet groove 2410. After the welding gun 250 is lowered to the specified height, it will pass through the welding hole to achieve the connection between one of the batteries and the nickel sheet. Later, when the hollow block 210 is reset, the top plate 2413 will contact the top of the inner wall of the welding frame 130, so that the movable rack 2412 will move to drive the hollow gear 246, and the hollow gear 246 will pass through the bevel block 24 8 drives the inner wheel 245, and the inner wheel 245 drives one of the long shafts 231 and the sprocket 232 to rotate through the transmission shaft 241 and the two bevel gears 242. The sprocket 232 will drive the chain 233 to roll a certain distance, and push the hollow frame 235 through the booster shaft 236. The hollow frame 235 drives the displacement block 234 and the welding gun 250 to move. At this time, the welding gun 250 is located above another battery. Subsequently, the incomplete gear 272 disengages from the first connecting gear 263 and drives the second connecting gear 295. The second connecting gear 295 drives the transmission roller 292 to drive the transmission belt 293 to roll, thereby driving multiple tooth blocks 294 to move. Subsequently, the incomplete gear 272 disengages from the second connecting gear 295 again The first connecting gear 263 is driven off, so that the welding gun 250 welds the next battery again, and the above operation is repeated to complete the welding of a row of batteries. After the last battery in a row is welded, the booster shaft 236 will flip from one side of the chain 233 to the other side, so as not to change the position of the welding gun 250. After the welding of a row of batteries is completed, when the incomplete gear 272 drives the second connecting gear 295, the multiple tooth blocks 294 will drive the pinion 283, and the pinion 283 drives the bidirectional screw rod 281 to rotate, and the rotation of the bidirectional screw rod 281 drives the two U-shaped blocks 282 to approach each other. At this time, the push-pull rod 285 pushes the long plate 284 to drive the moving slide plate 140 to move, so that another row of batteries moves to the bottom of the welding gun 250.The subsequent incomplete gear 272 reciprocates the first connecting gear 263 and the second connecting gear 295 again to complete the connection between the rectangular arrangement of batteries and nickel sheets, and complete the assembly connection of the batteries and nickel sheets, thereby improving welding safety, so that the device can realize automatic welding of rectangular arrangement of batteries and nickel sheets, with more accurate welding positions, higher automatic welding efficiency and greater convenience for use.
