[0023] It should be noted that: the rotating seat 4 drives the welding assembly to make a circular motion. When the welding groove 401 rotates to the feeding tube 2, the battery will fall into the automatic welding groove 401. At this time, the welding point between the connecting plate and the battery is facing the welding gun 9. As the welding assembly makes a circular motion, the driving gear 11 will rotate, thereby driving the driven gears 7 on both sides to rotate. The driven gear 7 drives one end of the swing arm 10 to rotate, thereby making the swing arm 10 drive the welding gun 9 to make a circular motion, realizing the welding function of the connecting plate and the battery, thereby realizing the function of simultaneous feeding and welding, and greatly improving the welding efficiency.

[0024] Furthermore, a fixing frame 6 is fixedly connected to one end of the housing 1, a fixing gear 5 is fixedly connected to the center of the fixing frame 6, and the fixing gear 5 is meshed with driving gears 11 at various locations;

[0025] It should be noted that the fixed gear 5 is arranged so that the driving gear 11 can rotate when performing circular motion, thereby driving the driven gears 7 on both sides to rotate, thereby providing driving force for the circular motion of the welding gun 9.

[0026] Furthermore, the bottom end of the housing 1 is fixedly connected to a support leg 3, the bottom end of the support leg 3 is fixedly connected to a bottom plate, a receiving box 13 is placed on the bottom plate, one end face of the housing 1 is fixedly connected to an L-shaped fixing rod, one end of the L-shaped fixing rod is fixedly connected to a mounting seat, a driving motor 14 is installed on the mounting seat, and the output shaft of the driving motor 14 is fixedly connected to the rotating seat 4;

[0029] When the utility model is in use, the battery stack is placed in the feed tube 2. When the driving motor 14 drives the rotating seat 4 to rotate, so that the welding groove 401 rotates to the feed tube 2, the battery will automatically fall into the welding groove 401, and the welding point between the connecting plate and the battery is directly opposite to the welding gun 9 (the connecting plate can be first bonded to the battery to play a temporary fixing role, which is convenient for the welding gun 9 to weld the welding point between the connecting plate and the battery). As the welding assembly makes a circular motion, the driving gear 11 will roll along the fixed gear 5, thereby driving the driven gears 7 on both sides to rotate, and the driven gear 7 drives one end of the swing arm 10 to rotate, so that the swing arm 10 drives the welding gun 9 to make a circular motion, realizing the welding function of the connecting plate and the battery, thereby realizing the function of automatic battery feeding and welding synchronously, and greatly improving the welding efficiency;
