The other end of the output shaft of the lifting motor 3 is fixedly sleeved with a rotating shaft 4. The outer surface of the rotating shaft 4 is fixedly sleeved with a rotating rod 5. The other end of the rotating rod 5 is fixedly sleeved with a round shaft 6. The outer surface of the round shaft 6 is movably connected to a hollow block 7. The outer surface of the hollow block 7 is movably connected to the inner surface of the rectangular box 1. The top of the hollow block 7 is fixedly connected to the bottom of the positioning plate 2. The hollow block 7 drives the positioning plate 2 to move upward to position the welding gap of the photovoltaic bracket.

[0029] When the lifting motor 3 operates, it will cause the rotating shaft 4 to drive the rotating rod 5 to rotate, and then cause the round shaft 6 to rotate to push the hollow block 7 and the positioning plate 2 to move upward, thus achieving the purpose of positioning the welding gap of the photovoltaic bracket.

[0030] Among them, the middle of the top of the rectangular box 1 is fixedly connected with a U-shaped bracket 8. The top of the front of the U-shaped bracket 8 is fixedly connected with a driving motor 9. The other end of the output shaft of the driving motor 9 is fixedly sleeved with a lead screw 10. The back of the lead screw 10 penetrates through the U-shaped bracket 8 and extends to the inside of the U-shaped bracket 8 and is threadedly sleeved with a movable plate 11. The outer surface of the movable plate 11 is movably connected to the inner surface of the top of the U-shaped bracket 8.

[0031] When the driving motor 9 operates, it will cause the lead screw 10 to rotate and drive the movable plate 11 to move left and right.

[0032] Among them, the top of the movable plate 11 is fixedly connected with a welding machine 12. The bottom of the welding machine 12 penetrates through the movable plate 11 and extends to the bottom of the movable plate 11 and is fixedly connected with a welding head 13.

[0033] When the welding machine 12 operates, it drives the welding head 13 to move downward to weld the photovoltaic bracket.

[0034] Among them, the bottom of the inner cavity of the rectangular box 1 is fixedly connected with transmission motors 14 located on the left and right sides of the lifting motor 3. The number of the transmission motors 14 is two. The other ends of the output shafts of the two transmission motors 14 are fixedly sleeved with transmission shafts 15. The outer surface of the transmission shafts 15 is fixedly sleeved with convex blocks 16.

[0041] The design of the smooth outer surface of the positioning plate 2 facilitates the up and down movement of the positioning plate 2 better inside the top of the rectangular box 1.

[0042] The working principle and usage process of the present utility model:

[0043] When welding two photovoltaic brackets, first place the two photovoltaic brackets on the top of the rectangular box 1, and then start the lifting motor 3, which will cause the rotating shaft 4 to drive the rotating rod 5 to rotate, and then cause the round shaft 6 to rotate to push the hollow block 7 and the positioning plate 2 to move upward. Subsequently, push the two photovoltaic brackets to fit with both sides of the positioning plate 2, thereby achieving the purpose of positioning the welding gap of the two photovoltaic brackets and ensuring the unity of the welding gap.

[0044] After that, start the two transmission motors 14, which will cause the two transmission shafts 15 to drive the two bumps 16 to rotate to relieve the squeezing effect on the four clamping plates 17. Due to the elastic force recovery of the four springs 18, the four clamping plates 17 move towards each other to automatically clamp and fix the two photovoltaic brackets. Finally, start the welding machine 12, which will drive the welding head 13 to move downward to weld the two photovoltaic brackets. At the same time, start the driving motor 9, which will cause the lead screw 10 to rotate to drive the whole movable plate 11 to move left and right, and then drive the welding head 13 to move left and right to weld different positions of the photovoltaic brackets.
