[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. All directional indications in the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship and movement status of the various components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] like Figure 1-5 As shown, this embodiment provides a profile corner weld welding equipment for welding rectangular structure air vent parts, including a machine base 1, a slide structure 2, a welding gun head 4, a table 5 and a positioning clamping mechanism. The machine base 1 is composed of a frame and sheet metal welded together by steel materials. The upper part is used to carry and fix the upper components, and the interior accommodates a laser generator, an electrical control unit device, etc. The slide structure 2 is installed on one side of the machine base 1. A cantilever 3 is provided on the slide structure 2. The slide structure 2 drives the cantilever 3 to move on the vertical plane. The welding gun head 4 is installed at the lower end of the cantilever 3 and is used for welding the corner seams of the profile 12. In this embodiment, the welding gun head 4 is a laser welding gun head 4. The laser beam generated by the laser is focused into a point through the welding gun head 4, generating high temperature on the welding surface to fuse the two workpieces.

[0025] The table plate 5 is located below the welding gun head 4 and is fixed on the machine base 1. The table plate 5 is located on one side of the slide structure 2. Two sets of symmetrically arranged positioning and clamping mechanisms are installed on the table plate 5. The positioning and clamping mechanisms include a positioning structure 6 and a clamping structure 7.

[0026] like Figure 1As shown, in this example, the slide structure 2 includes an X-axis slide 21 and a Z-axis slide 22. The X-axis slide 21 is fixed to the upper surface of the machine base 1, and the lower end of the Z-axis slide 22 is mounted on the X-axis slide 21 and the X-axis slide 21 drives the Z-axis slide 22 to move along the X-axis direction. The cantilever 3 is mounted on the Z-axis slide 22, and the Z-axis slide 22 drives the cantilever 3 to move along the Z-axis direction, and then the slide structure 2 drives the welding gun head 4 to move in the horizontal and vertical directions. Both the X-axis slide 21 and the Y-axis slide are equipped with high-precision servo drives and guide mechanisms, which are used to drive the Y-axis slide and the cantilever 3, respectively. The setting of the slide structure 2 can accurately and controllably drive the welding gun head 4 to move up, down, left and right to adapt to the changes and movement needs of the horizontal direction of the weld of the profile 12.

[0027] Furthermore, a welding monitor 9 is provided on the machine base 1 for real-time magnified observation of the weld fusion effect, and a control panel 10 is provided on the front side of the machine base 1 for installing switch buttons to control the start and stop of the equipment. Foot switches 11 are provided on both sides of the machine base 1 to trigger the start signal and material removal signal of the welding work, one on each left and right workstation, for controlling the positioning and clamping mechanism and the slide structure 2.

[0028] like Figure 2-4 As shown, in this example, the positioning structure 6 includes two vertically diagonally arranged pads 61, on which are respectively fixed vertically arranged positioning strips 62. Positioning angles 63 are provided at the diagonal positions of the two pads 61. The welding corners of the two profiles 12 abut against the positioning angles 63, so that the corner seams below the two profiles 12 are closed. During welding, the worker holds the two profiles 12 so that the outer edges of the profiles 12 are against the positioning strips 62. The positioning strips 62 are used to guide and position the profiles 12 to ensure the accuracy of the welding angle. After the two profiles 12 are diagonally aligned, they are tightly against the positioning angles 63, ensuring that the weld seams of the two profiles 12 fit together and the accuracy of the welding angle is ensured.

[0029] like Figure 2-5As shown, further, the positioning structure 6 also includes an adjustable closing push rod device 8, which is provided in two groups. The adjustable closing push rod device 8 is used to abut the top of the two profiles 12 at the diagonal positions, so that the corner gaps above the two profiles 12 are closed. Specifically, the adjustable closing push rod device 8 includes a closing cylinder 81, a push rod seat 82, a vertical rod 83, a cross-opening clamp 84, a cross bar 85 and a push rod head 86. The closing cylinder 81 is fixed to the table 5 through the closing cylinder 81 seat. The telescopic end of the closing cylinder 81 fixes the push rod seat 82, and the push rod seat 82 is fixedly connected to the vertical rod 83. The vertical rod 83 and the cross bar 85 both slide through the cross-opening clamp 84, and the vertical rod 83 and the cross bar 85 are vertically arranged. The cross-opening clamp 84 is fixed to the cross bar 85 or The vertical rod 83 and the push rod head 86 are fixed to one end of the cross bar 85. The closed cylinder 81 pushes the push rod seat 82, and the push rod seat 82 is used to push the push rod head 86. The push rod head 86 abuts against the upper end of the profile 12, so that the upper ends of the two profiles 12 at the butt angle are tightly fitted, thereby closing the weld. The cross-open clamp 84 can adjust the cross bar 85 to move forward and backward, up and down, and swing at an angle, and then adjust the position of the push rod head 86. After adjusting according to the needs of the profile 12, tighten the screws at the cross-open clamp 84 to fix it. A pull rod seat 87 is fixedly connected to one side of the closing cylinder 81, and a limiting pull rod 88 is fixedly connected to the pull rod seat 87. The limiting pull rod 88 is slidingly connected to the top rod seat 82. A section of the limiting pull rod 88 close to the pull rod seat 87 is a screw and is threadedly connected to the pull rod seat 87, and a limiting block is provided at the end of the limiting pull rod 88 away from the pull rod seat 87 to limit the forward movement of the closing cylinder 81. The screw part of the limiting pull rod 88 cooperates with the pull rod seat 87 to control the stroke to match the position of the profile 12. After welding is completed, the closing cylinder 81 retracts and the workpiece is taken out.

[0030] like Figure 2 As shown, the clamping structure 7 is provided in two groups, and the clamping structure 7 includes a clamping cylinder 71, a pressure seat 72, and a pressure claw 73. The clamping cylinder 71 is fixed to the bottom of the table 5. The telescopic end of the clamping cylinder 71 passes through the table 5 and is fixedly connected to the pressure seat 72. The pressure claw 73 is fixed to the pressure seat 72. The clamping cylinder 71 drives the pressure seat 72 to move downward, driving the pressure claw 73 to press on the profile 12, thereby clamping and fixing the profile 12. The clamping structure 7 is also provided in two groups and is provided in a one-to-one correspondence with the backing plate 61 and the positioning bar 62.

[0031] Its working principle is as follows: a worker holds two profiles 12 to be welded, and places the two profiles 12 tightly against the positioning strips 62 respectively. The butt corners of the two profiles 12 are fitted with the positioning angles 63, and the weld seams at the lower ends of the two profiles 12 are closed. The clamping cylinder 71 drives the pressing claws 73 to clamp and fix the profile 12. At the same time, the closing cylinder 81 drives the push rod seat 82 to move, so that the push rod head 86 moves forward to facilitate contact with the upper end of the profile 12, so that the weld seams of the two profiles 12 are closed. The slide structure 2 drives the laser welding gun head 4 to weld the welds of the two profiles 12, realizing automated welding, improving production efficiency, reducing scrap rate, and ensuring consistency of welding quality. It is a perfect fusion of automated control technology and laser welding technology, making product production more efficient, more economical, more intelligent, and of higher quality, in line with the needs of modern industrial production.
