[0023] The present invention will be described in detail below with reference to the accompanying drawings.

[0024] An automatic welding platform for anti-theft doors, such as Figures 1 to 4 As shown, it includes a processing box 1 and a box door 2. Two support plates 3 are fixedly installed in the inner cavity of the processing box 1. A slide groove 4 is provided at the lower end of the two support plates 3. A groove 5 is provided on the middle side of the upper end of the two support plates 3. A driving mechanism 6 is provided in the slide groove 4. A U-shaped slide plate 7 is threadedly connected to the left and right sides of the outer surface of the driving mechanism 6. A clamping plate 8 is fixedly installed on the front and back sides of the bottom of the inner cavity of the U-shaped slide plate 7. The clamping plate 8 is located at the opposite surface position of the two support plates 3. A cylinder 9 is fixedly installed at the rear end of the processing box 1. A movable frame 10 is fixedly installed at the output end of the cylinder 9. A welding head 11 is provided in the movable frame 10. The opening of the slide groove 4 of the support plate 3 is set downward, so that the debris generated during the welding process of the door panel cannot fall into the slide groove 4 and cause its opening to be blocked.

[0025] like Figure 4 As shown, the driving mechanism 6 includes a servo motor 61, and the output end of the servo motor 61 is fixedly installed with a forward and reverse threaded rod 62, and the forward and reverse threaded rod 62 moves in the front side slide 4. The servo motor 61 is fixedly connected to the right end of the processing box 1, and the U-shaped slide 7 is threadedly connected to the forward and reverse threaded rod 62. When the servo motor 61 is started, the forward and reverse threaded rod 62 rotates, driving the U-shaped slide 7 to move left and right in the slide 4, thereby adjusting the spacing between the splints 8 to adapt to door panels of different widths.

[0026] like Figure 1 As shown, four supporting legs 12 are fixedly installed at the lower end of the processing box 1. The supporting legs 12 provide support and stability for the processing box 1 to ensure the stability of the equipment.

[0027] like Figure 1 As shown, a sealed visual window 13 is provided on the front side of the box door 2. The sealed visual window 13 adopts double-layer tempered glass, so that the operator can clearly observe the clamping state of the door panel, the movement trajectory of the welding head 11 and the weld forming quality without opening the box door 2. The inner side of the glass of the sealed visual window 13 is covered with a high-temperature resistant transparent protective film (made of polyimide, temperature resistant ≥300°C), which can prevent welding spatter from directly impacting the glass surface and reduce the stimulation of strong light (arc light) to the operator's eyes.

[0028] A curved plate 14 is fixedly mounted in the middle of the inner cavity of the U-shaped slide 7, and is located between the opposing surfaces of the two clamping plates 8. The curved plate 14 is provided so that the debris generated during door panel processing falls down along the curved surface of the curved plate 14 to the collection box 15 below for collection.

[0029] A collecting box 15 is provided at the bottom of the inner cavity of the processing box 1. The collecting box 15 provided at the bottom of the inner cavity of the processing box 1 can collect waste materials and metal particles generated during the welding process in a timely manner to keep the working environment clean.

[0030] Working Principle: To use the present invention, the operator first opens the door 2 and places the door panel to be welded in the groove 5 on the two support plates 3. The operator then activates the servo motor 61, a device that converts electrical energy into mechanical energy. Because the left and right ends of the threaded rod 62 have threads with different rotational directions, the nuts or slides 7 with nuts provided at each end of the threaded rod 62 can move relative to each other. The threaded rod 62 drives the U-shaped slide 7 to move left and right, adjusting the spacing between the clamps 8 so that the clamps 8 firmly clamp the two sides of the door panel. Next, the operator closes the door 2 and activates the cylinder 9, causing the movable frame 10 to move the welding head 11 downward to above the door panel to begin welding. After welding is completed, the cylinder 9 drives the welding head 11 upward and resets it. The servo motor 61 is activated again, driving the U-shaped slide 7 to move, loosening the clamps 8, and removing the welded door panel. The design of the drive mechanism 6 and clamps 8 effectively limits and fixes the door panel, preventing positional shifting during welding and improving welding accuracy.

[0031] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
