[0040] By adopting the above scheme, the wire feeder 104 moves upward, and the rack 103 causes the first gear 105 to rotate in the direction opposite to the rotation direction of the driving gear 102. The rotation of the first gear 105 drives the second gear 106 to rotate. The rotation of the second gear 106 drives the transmission gear 108 to rotate through the two bevel gears 107. The rotation of the transmission gear 108 drives the driven gear 109 to rotate. The rotation of the driven gear 109 drives the rotating housing 206 to rotate.

[0044] The above scheme is adopted: by setting the cooperation of structures such as the fixing plate 402 and the clamping block 308, the loading and unloading of the welding head main body 401 is facilitated, the fixing plate 402 on the top of the welding head main body 401 is aligned with the groove 306 and the fixing plate 402 is moved to the inside of the groove 306, and then the welding head main body 401 is rotated in the direction close to the clamping groove 307. During the rotation process, the fixing plate 402 will squeeze the inclined surface of the clamping block 308, and the clamping block 308 is moved from the inside of the clamping groove 307 to the inside of the fixed shell 301 and squeezes the fixed shell 301 by squeezing the inclined surface. When the end of the fixing plate 402 away from the welding head main body 401 is clamped between the clamping groove 307, the fixing hole 403 is aligned with the clamping block 308. At this time, the clamping block 308 is clamped between the fixing hole 403 under the action of the elastic force of the spring 310, and the welding head main body 401 is fixed to the bottom of the fixed shell 301, which is convenient for the staff to select and replace the appropriate welding head main body 401 according to the welding type.

[0045] The working principle and use process of the present invention are as follows: first, according to the material, thickness and welding requirements of the new energy battery, the welding current, voltage, wire feeding speed and other parameters are preset, and according to the welding type, a suitable welding head body 401 is selected, such as MIG / MAG, TIG or laser welding head, and then the fixing plate 402 on the top of the welding head body 401 is aligned with the groove 306 and the fixing plate 402 is moved to the inside of the groove 306, and then the welding head body 401 is rotated in the direction close to the card slot 307. During the rotation process, the fixing plate 402 will squeeze the inclined surface of the card block 308, and the card block 308 is moved out of the card slot 307 by squeezing the inclined surface. 07 moves to the inside of the fixed shell 301 and squeezes the fixed shell 301. When the end of the fixing plate 402 away from the welding head body 401 is engaged with the card slot 307, the fixing hole 403 is aligned with the card block 308.

The rotation of the driving gear 102 will drive the wire feeder 104 to move upward inside the third slide trough 305 through the rack 103, and drive the welding wire 110 to move away from the welding head body 401. At the same time, the upward movement of the wire feeder 104 will cause the first gear 105 to rotate in the opposite direction of the rotation direction of the driving gear 102 through the rack 103. The rotation of the first gear 105 will drive the second gear 106 to rotate, and the rotation of the second gear 106 will drive the second gear 106 to rotate through the two bevel gears 107. The transmission gear 108 rotates, and the rotation of the transmission gear 108 drives the driven gear 109 to rotate. The rotation of the driven gear 109 drives the rotating shell 206 to rotate. The rotation of the rotating shell 206 causes the slide bar 205 to slide inside the second slide groove 207. At the same time, the baffle 203 slides between the slider 204 on its top and the first slide groove 202, so that the six baffles 203 slide away from each other, and the hexagonal liquid outlet area formed between the six baffles 203 is expanded. The coolant is moved to the cooling groove 302 on the welding head body 401 through the water pump 201 to cool the welding head body 401.
