The output end of the motor 21 passes through the frame 1 and is fixedly connected to a support frame 22. The four corners of the upper end of the support frame 22 are all connected to fixing components 23; Reference Figure 3 The fixing assembly 23 includes two symmetrically arranged mounting plates 231, which are fixedly connected to the upper end of the support frame 22. A first connecting shaft is rotatably connected between the two symmetrically arranged mounting plates 231, and an extrusion plate 232 is fixedly connected to the first connecting shaft. One end of the extrusion plate 232 is located in the support frame 22, and a cylinder 233 is fixedly connected to the support frame 22, and the telescopic end of the cylinder 233 is rotatably connected to the extrusion plate 232.

[0017] Working principle: The battery box is placed in the support frame 22, and the support frame 22 cooperates with the battery box. After the cylinder 233 is started, the extrusion plate 232 is pushed to rotate upward, and the extrusion plate 232 rotates around the first connecting axis. One end of the extrusion plate 232 rotates toward the inner wall of the support frame 22. After the extrusion plate 232 rotates a certain angle, it contacts the inner wall of the battery box. Several extrusion plates 232 squeeze the four corners of the battery box, so as to fix the battery box. After the motor 21 is started, it drives the support frame 22 to rotate a set number of circles, and the support frame 22 drives the battery box to rotate to adjust the position of the battery box. After the horizontal driving machine 3 is started, it drives the groove frame 4 to move in the horizontal direction, the groove frame 4 drives the movable plate 5 to move, and the movable plate 5 drives the welding gun head 7 to move. When the welding gun head 7 is located directly above the welding position of the battery box, the horizontal driving machine 3 stops driving the groove frame 4 to move, the heater 10 and the fan 11 are powered on and started, and the heater 10 heats the gas in the open box 9 after starting, and the fan 11 sucks the gas after starting, and the sucked gas enters the open box 9 and contacts with the heater 10 for heating, and the heated gas enters the conduit 12, and the hot gas in the conduit 12 enters the annular tube 13, and the hot gas in the annular tube 13 is released from different outlet pipes 14, and the gas released from the outlet pipe 14 flows downward; After the electric telescopic rod 6 is powered on and started, it drives the movable plate 5 to move downward by a set distance. While the movable plate 5 moves downward, it drives the open box 9 to move through the dislocation mechanism 8. The open box 9 drives the guide tube 12 to move downward. The guide tube 12 drives the annular tube 13 to move. The annular tube 13 drives the air outlet pipe 14 to move downward. The distance between the bottom end of the air outlet pipe 14 and the welding position of the battery box gradually decreases. After the air outlet pipe 14 moves downward for a certain distance, the hot gas released from the air outlet pipe 14 begins to contact the welding position of the battery box. After the movable plate 5 moves downward by a set distance, the air outlet pipe 14 stops moving downward. In the process from the hot gas released by the air outlet pipe 14 initially contacting the welding position of the battery box to the air outlet pipe 14 moving downward to the lowest end position, the hot gas released from the air outlet pipe 14 continues to contact the welding position of the battery box. The hot gas preheats the welding position of the battery box to increase the temperature of the welding position of the battery box. After the movable plate 5 moves downward by a set distance, the welding gun head 7 releases the laser to pass through the annular tube 13 to perform welding processing on the battery box welding part. Since the battery box welding part is in contact with the hot gas released by the outlet pipe 14 before welding, the temperature of the battery box welding part increases. When the laser is used to weld the battery box welding part, after preheating the welding part in advance, the uneven temperature field caused by excessive heating speed is avoided, thereby reducing the internal stress generated in the welding part, and it is not easy to produce cracks and deformation after welding, thereby improving the welding quality; After welding is completed, the electric telescopic rod 6 drives the movable plate 5 to move upward and reset, and the movable plate 5 drives the welding gun head 7 to move upward and reset.

[0018] Embodiment 2: The hot gas is released through the outlet pipe 14 to preheat the battery box welding part, and then the battery box welding part is welded through the welding gun head 7. Since the distance between the bottom end of the outlet pipe 14 and the battery box welding part is short, when the welding gun head 7 releases the laser to weld the battery box welding part, the debris generated by the welding is easy to adhere to the outlet of the outlet pipe 14, thereby affecting the release of hot gas from the outlet pipe 14. Figure 4-6As another preferred embodiment of the present invention, the difference from Embodiment 1 is that the dislocation mechanism 8 includes a movable frame 81, the movable frame 81 is slidably connected to the movable plate 5, the movable frame 81 is fixedly connected to the open box 9, the movable frame 81 is fixedly connected to a spring 82, one end of the spring 82 is fixedly connected to the movable plate 5, the groove frame 4 is fixedly connected to a mounting frame 831, the mounting frame 831 is rotatably connected to a gear 832 via a second connecting shaft, the movable plate 5 is fixedly connected to a first tooth plate 833, the first tooth plate 833 is meshed with the gear 832, the mounting frame 831 is slidably connected to a second tooth plate 834, the second tooth plate 834 is meshed with the gear 832, and the upper end of the second tooth plate 834 is fixedly connected to a top block 835.

[0019] Working principle: The movable plate 5 drives the movable frame 81 to move in the process of moving downward, and the movable plate 5 also drives the first tooth plate 833 to move downward. After the first tooth plate 833 moves downward, it drives the gear 832 to rotate. After the gear 832 rotates, it drives the second tooth plate 834 to move upward. The second tooth plate 834 moves smoothly under the limit of the mounting frame 831. The second tooth plate 834 drives the top block 835 to move upward. After moving upward for a distance, the top block 835 contacts the bottom end of the movable frame 81. At this time, the distance between the outlet end of the air outlet pipe 14 and the welding position of the battery box is the smallest. As the movable plate 5 continues to move downward, the top block 835 pushes the movable frame 81 to move upward. After the movable frame 81 moves upward, it pulls the spring 82. The spring 82 is pulled to generate elastic force. After the top block 835 pushes the movable frame 81 to move upward, the movable frame 81 drives the open box 9 to move upward, the open box 9 drives the conduit 12 to move upward, the conduit 12 drives the annular tube 13 to move upward, the annular tube 13 drives the outlet pipe 14 to move upward, and after the annular tube 13 moves upward for a distance, the welding gun head 7 passes through the annular tube 13, and the distance between the bottom end of the outlet pipe 14 and the welding point of the battery box gradually increases. When the movable plate 5 drives the welding gun head 7 to move downward for a set distance, there is a certain distance between the bottom end of the outlet pipe 14 and the welding point of the battery box. When the welding gun head 7 performs laser welding on the welding point of the battery box, since there is a certain distance between the bottom end of the outlet pipe 14 and the welding point of the battery box, the debris generated by welding will not adhere to the outlet end of the outlet pipe 14, thereby not affecting the release of hot gas from the outlet pipe 14. After welding is completed, the movable plate 5 moves upward to reset, and the first tooth plate 833 moves upward to drive the second tooth plate 834 to move downward to reset through the gear 832. During the upward movement and reset of the movable plate 5, the elastic force generated by the spring 82 pushes the movable frame 81 to move and reset.

[0020] Embodiment 3: When the top block 835 pushes the movable frame 81 to move upward, the annular tube 13 moves upward. After the annular tube 13 moves upward, the welding gun head 7 passes through the annular tube 13. At this time, the outlet of the gas outlet pipe 14 is located outside the welding gun head 7. The hot gas released from the gas outlet pipe 14 contacts the gun body of the welding gun head 7, thereby causing the welding gun head 7 to heat up, which is not conducive to the operation of the welding gun head 7. Figure 7-9 As another preferred embodiment of the present invention, the difference from Embodiment 2 is that a barrier mechanism 15 for heat insulation is connected to the bottom end of the movable plate 5, the barrier mechanism 15 comprises a connecting plate 151, one end of the connecting plate 151 is fixedly connected to the movable plate 5, the other end of the movable plate 5 is fixedly connected to a first heat-insulating tube 152, the welding gun head 7 passes through the first heat-insulating tube 152, a slide groove 153 is provided on the first heat-insulating tube 152, a roller 154 is rollingly connected to the slide groove 153, a second heat-insulating tube 155 is connected to the roller 154, the second heat-insulating tube 155 is located on the outside of the first heat-insulating tube 152, and a wiping sleeve 156 is sleeved on the second heat-insulating tube 155.

[0021] Working principle: The connecting plate 151 fixes the first heat-insulating tube 152, and the first heat-insulating tube 152 is connected to the second heat-insulating tube 155 through the roller 154. The first heat-insulating tube 152 and the second heat-insulating tube 155 are located on the outside of the welding gun head 7. The top block 835 pushes the movable frame 81 to move upward, so that when the annular tube 13 moves upward, the outlet of the gas outlet pipe 14 is located on the outside of the second heat-insulating tube 155. The first heat-insulating tube 152 and the second heat-insulating tube 155 block the hot gas released by the gas outlet pipe 14 to prevent the hot gas from contacting the welding gun head 7, thereby not affecting the operation of the welding gun head 7. The annular tube 13 drives the air outlet pipe 14 to move as it moves upward, and the air outlet end of the air outlet pipe 14 contacts the wiping sleeve 156. The wiping sleeve 156 cleans the air outlet end of the air outlet pipe 14. The hot gas released by the air outlet pipe 14 pushes the wiping sleeve 156. The wiping sleeve 156 drives the second insulation tube 155 to rotate. The second insulation tube 155 rotates on the first insulation tube 152 through the roller 154, so that different positions of the wiping sleeve 156 contact the air outlet end of the air outlet pipe 14, thereby improving the cleaning effect of the air outlet of the air outlet pipe 14.
