[0029] like Figure 1-2 As shown, a metal plate welding equipment for shelf production includes a support frame 1 and a square plate 2. The square plate 2 is rotatably connected between the inner walls of the support frame 1 via a rotating shaft 3 and a round shaft 4. A reinforcing rod 21 is fixedly connected between the inner walls of the support frame 1 to increase the stability of the support frame 1. The equipment also includes a positioning component and a flipping component.

[0030] like Figure 1-6As shown, to ensure stable contact of the weld joints, a positioning assembly is installed on the square plate 2, including a bracket 5 on the top of the square plate 2 and a positioning mechanism on the bracket 5. The bracket 5 has two sets: one set is fixed to the top of the square plate 2, and the other set slides laterally on the square plate 2 via an adjustment mechanism. The positioning mechanism includes a horizontal plate 6, a stepper motor 7, a cam 8, a sliding column 9, and a pressure plate 10. The horizontal plate 6 is fixed to the outer wall of the bracket 5, and has a through hole 11 in its middle. The stepper motor 7 is fixed to the top of the horizontal plate 6. The cam 8 is fixed to the output end of the stepper motor 7 and is located directly above the through hole 11. The sliding column 9 vertically penetrates the horizontal plate 6 and slides with it, and is symmetrically distributed front and back. A spring 24 is fitted on the sliding column 9, and its two ends are fixed to the sliding column 9 and the horizontal plate. 6. The pressure plate 10 is fixed to the lower end of the sliding column 9. The front and rear sides of the bracket 5 are provided with evenly distributed protruding columns 22 for limiting the side of the metal plate. The adjustment mechanism includes a linear guide rail 12, a slider 13 and a connecting frame 14. The linear guide rail 12 is fixedly installed on the bottom wall of the square plate 2. The slider 13 slides horizontally on the linear guide rail 12. The square plate 2 is provided with stroke holes 15 symmetrically distributed front and rear. The connecting frame 14 is fixed to the bottom wall of the slider 13 and is arranged in a U-shape. The upper end of the connecting frame 14 passes through the stroke hole 15 and is fixedly connected to the bottom wall of one of the brackets 5. The rotation of the cam 8 applies pressure to the pressure plate 10 to press and position the metal plate. The slider 13 drives the connecting frame 14 to slide laterally until the end faces of the two metal plates are in contact to ensure stable contact of the weld point.

[0031] like Figure 1-5 As shown, to facilitate welding to the other side of the metal plate, a flipping assembly is located on both sides of the support frame 1. This assembly includes a flipping mechanism for adjusting the orientation of the square plate 2 and a limiting mechanism for increasing stability. The flipping mechanism includes a servo motor 16, a worm gear 17, and a worm wheel 18. The servo motor 16 is fixedly mounted on the outer wall of the support frame 1. The worm gear 17 is fixedly connected to the output end of the servo motor 16. The worm wheel 18 is fixedly connected to the rotating shaft 3 and meshes with the worm gear 17. The limiting mechanism includes a disc 19 and a limiting block 20. The disc 19 is fixed to the round shaft 4, and the limiting block 20 is fixed to the outer wall of the support frame 1. The cross-sections of the disc 19 and the limiting block 20 are both C-shaped. One side of the disc 19 is located inside the inner wall of the limiting block 20. The square plate 2 is provided with through holes 23, which are arranged linearly. The through holes 23 are located between the two sets of supports 5. The meshing transmission of the worm gear 17 and the worm wheel 18 causes the rotating shaft 3 and the round shaft 4 to rotate, thereby flipping the square plate 2. The welding equipment can weld the flipped metal plate through the through holes 23.

[0032] In practical use, the two metal plates to be welded are placed between the protrusions 22 on the two supports 5 respectively. The stepper motor 7 is turned on, and the rotation of the cam 8 applies pressure to the pressure plate 10 through the through hole 11. The downward movement of the pressure plate 10 can press and position the metal plates. The linear guide rail 12 controls the slider 13 to drive the connecting frame 14 to slide laterally until the end faces of the two metal plates are in contact, ensuring stable contact of the weld point. Then, the metal plates can be welded by the welding equipment. After the single-sided welding is completed, the servo motor 16 is turned on, and the meshing transmission of the worm gear 17 and the worm wheel 18 causes the rotating shaft 3 and the round shaft 4 to rotate, thereby flipping the opposite side of the plate 2. During the flipping process, the disc 19 rotates inside the limit block 20, which can increase the stability of the rotating shaft 3. The protrusions 22 can prevent the metal plates from falling off the supports 5 during the flipping process. The welding equipment can weld the other side of the metal plate through the through hole 23. After the welding is completed, the rotation of the cam 8 can reset the pressure plate 10 under the action of the spring 24 and the sliding column 9, thereby allowing the metal plate to be pulled out.
