[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] like Figures 1-12 As shown, the present invention employs the following technical solution: a manufacturing robot welding and inspection integrated workbench, comprising a support platform 1, a welding robot 38, a mounting mechanism, and a detection mechanism. Both the mounting mechanism and the detection mechanism are mounted on the support platform 1. A plate body 40 to be welded is placed on the mounting mechanism, and the welding robot 38 welds the plate body 40. After welding is completed, the detection mechanism inspects the weld.

[0034] The welding robot 38 is mounted above the support platform 1 and is configured in conjunction with a mounting mechanism. A vertical plate 2 is fixedly mounted on one side of the support platform 1. The vertical plate 2 is connected to a lifting plate 5 for vertical movement. Specifically, the vertical plate 2 defines a first mounting slot, within which a first threaded rod 3 is vertically and rotatably mounted. One end of the lifting plate 5 is limitedly slidably mounted within the first mounting slot and threadedly connected to the first threaded rod 3. A first motor 4 is fixedly mounted at the top of the vertical plate 2, with its motor shaft fixedly connected to the first threaded rod 3. The lifting plate 5 defines a second mounting slot, within which a third threaded rod 34 is rotatably mounted. A second motor 6, which drives the third threaded rod 34, is fixedly mounted on the lifting plate 5. A slide 35 is fixedly mounted in the second mounting slot for limited sliding movement. The slide 35 is threadedly connected to the third threaded rod 34. A fixed block is slidably mounted on the slide 35. A fourth threaded rod 37 is rotatably mounted on the slide 35. A fifth motor 36, which drives the fourth threaded rod 37, is fixedly mounted on the slide 35. The fixed block is threadedly connected to the fourth threaded rod 37. The welding robot 38 is mounted on the fixed block.

[0035] The mounting mechanism includes a support frame 13, a fixed frame 19, and a sliding frame 24. There are two support frames 13, which are symmetrically arranged. In this embodiment, one support frame 13 is fixedly connected to the support platform 1, and the other support frame 13 is movably arranged on the support platform 1. Specifically, a fixed plate 26 is fixedly mounted on the support platform 1, and a first electric push rod 27 is fixedly mounted on the fixed plate 26. The first electric push rod 27 is fixedly connected to the corresponding support frame 13. A guide rod 28 is fixed to the fixed plate 26, and the guide rod 28 is slidably connected to the corresponding support frame 13.

[0036] Each support frame 13 is fixed with a fixed rod 18, and each fixed rod 18 is rotatably connected to a fixed frame 19. The middle portion of the fixed frame 19 is rotatably connected to the fixed rod 18. Each fixed frame 19 is limitedly slidably connected to a sliding frame 24. Figure 4 As shown, a second electric push rod 29 is fixedly provided in the sliding frame 24, and a pressing plate 30 is fixedly connected to the telescopic end of the second electric push rod 29. One side of the welding plate body 40 is placed in the sliding frame 24, and then the pressing plate 30 is moved close to the welding plate body 40 to clamp and fix the welding plate body 40.

[0037] The support frame 13 is provided with a limiting groove 39 . The end of the sliding frame 24 is slidably matched with the limiting groove 39 , and the end of the sliding frame 24 is arranged in an arc shape so that the sliding frame 24 can slide along the limiting groove 39 smoothly.

[0038] In this implementation, if Figure 10 As shown, the horizontal distance from the rotation axis of the fixed frame 19 to the inner wall of the limiting groove 39 is smaller than the vertical distance from the rotation axis of the fixed frame 19 to the inner wall of the limiting groove 39. Figure 11 、 Figure 12 As shown, when the fixed frame 19 is horizontal, both ends of the sliding frame 24 contact the inner wall of the limiting groove 39. When the fixed frame 19 rotates toward the vertical position, it drives the sliding frame 24 to rotate. Under the action of gravity, one end of the sliding frame 24 gradually moves downward along the fixed frame 19, and the downward end of the sliding frame 24 slides along the inner wall of the limiting groove 39. When the fixed frame 19 moves from the vertical position to the horizontal position, one end of the sliding frame 24 slides along the inner wall of the limiting groove 39. Under the restraint of the limiting groove 39, the end of the sliding frame 24 in contact with the inner wall of the limiting groove 39 gradually moves closer to the fixed frame 19 until the fixed frame 19 returns to the horizontal position, and both ends of the sliding frame 24 contact the inner wall of the limiting groove 39. The fixed frame 19 drives the welding plate body 40 to flip through the sliding frame 24, thereby turning the welding plate body 40 over.

[0039] Brackets 23 are rotatably mounted on the upper and lower sides of one fixed frame 19, with sandpaper 25 mounted on each bracket. A fourth motor 22 is fixedly mounted on the fixed frame 19 to drive the bracket 23. This ensures that the sandpaper 25 is in close contact with the weld seam on the welding plate body 40. As the fixed frame 19 rotates, the sliding frame 24 moves relative to the fixed frame 19, causing the sandpaper 25 to move along the weld seam on the welding plate body 40, grinding the weld seam and removing any weld slag.

[0040] A driving assembly for driving the fixed frame 19 to rotate is provided on the support frame 13. The driving assembly includes a gear 20, a rack 21 and a driving member for driving the rack 21 to move. A limiting rod 17 is fixedly installed on the support frame 13, and the rack 21 is slidingly limited on the limiting rod 17. The gear 20 is fixedly connected to the fixed frame 19, and the gear 20 is engaged with the rack 21. The rack 21 moves along the limiting rod 17, thereby causing the gear 20 to rotate and the fixed frame 19 to rotate. The driving member includes a guide plate 16, and the guide plate 16 is connected to the support frame 13 for sliding up and down. A third motor 14 is fixedly installed on the support frame 13, and the motor shaft of the third motor 14 is fixedly connected to the second threaded rod 15, and the second threaded rod 15 is vertically arranged. The second threaded rod 15 is threadedly connected to a connecting block, and the connecting block is fixedly connected to the guide plate 16.

[0041] like Figure 5 、 Figure 6 As shown, a guide groove 31 is provided on the guide plate 16. The guide groove 31 is arranged at an angle. In this embodiment, the lower end of the guide groove 31 is inclined in a direction close to the middle of the limiting groove 39. The guide groove 31 is wavy. The guide groove 31 includes a first guide section 32 and a second guide section 33. There are multiple first guide sections 32 and second guide sections 33, and the multiple first guide sections 32 and second guide sections 33 are arranged at intervals and the first guide sections 32 and second guide sections 33 are connected end to end in sequence. The lower end of the first guide section 32 is inclined in a direction close to the middle of the limiting groove 39, and the lower end of the second guide section 33 is inclined in a direction away from the middle of the limiting groove 39. The length of the first guide section 32 is greater than the length of the second guide section 33.

[0042] A guide block 41 is slidably provided in the guide groove 31, and the rack 21 and the guide block 41 are fixedly connected. When the guide plate 16 moves upward, the guide block 41 slides along the guide groove 31, thereby causing the rack 21 to swing left and right, the fixed frame 19 to swing up and down, and the welding plate body 40 to shake up and down, which helps to make the welding slag on the welding plate body 40 fall off. Specifically, when the guide block 41 moves along the first guide section 32, the guide block 41 moves to the left. Thereafter, the guide block 41 enters the second guide section 33, and when the guide block 41 moves along the second guide section 33, the rack 21 moves to the right. Since the lower end of the guide groove 31 is inclined toward the middle of the limit groove 39, the rack 21 moves to the left as a whole during the left and right swing.

[0043] A collecting box 12 is provided between the two supporting frames 13 on the supporting platform 1. Welding slag dropped from the welding plate body 40 falls into the collecting box 12.

[0044] like Figure 1 、 Figure 3As shown, the detection mechanism includes a weld detector 7 and a slider 11. An electric slide rail 10 is installed on the support platform 1, and the electric slide rail 10 is equipped with an electric slider, and the slider 11 is connected to the electric slider. A connecting frame 8 is fixedly installed on the support platform 1, and the weld detector 7 is installed on the connecting frame 8. The detector probe 9 on the connecting frame 8 is set vertically downward. The detector probe 9 is set in conjunction with the slider 11. During the inspection, the welded welding plate body 40 is placed on the slider 11, and the weld is directly below the detector probe 9. Then the slider 11 is moved along the electric slide rail 10, and the detector probe 9 detects the weld.

[0045] Working principle: Initially, the fixed frame 19 is in a horizontal state. The two ends of the sliding frame 24 are against the inner wall of the limit groove 39. The guide block 41 is at the upper end of the guide groove 31.

[0046] During use, the two welding plate bodies 40 are respectively inserted into the two sliding frames 24, and the second electric push rod 29 is activated to press the pressure plate 30 against the welding plate bodies 40, thereby fixing the welding plate bodies 40. Then, the first electric push rod 27 is activated to push the corresponding support frame 13 to slide, so that the two welding plate bodies 40 are connected.

[0047] Next, the first motor 4 is activated, lowering the lifting plate 5 and bringing the welding robot 38 closer to the welding plate body 40. The fifth motor 36 is activated, adjusting the position of the welding robot 38 so that it faces the joint between the two welding plate bodies 40. The second motor 6 and the welding robot 38 are activated, and the welding robot 38 begins welding.

[0048] When the welding robot 38 completes welding the first surface of the welding plate body 40, the second motor 6 is started to return the lifting plate 5 to the top of the first threaded rod 3. The upper bracket 23 is rotated to make the sandpaper 25 close to the weld seam on the first surface of the welding plate body 40.

[0049] The third motor 14 is activated, causing the guide plate 16 to move upward. The guide block 41 slides along the guide slot 31. Guided by the guide slot 31, the rack 21 moves leftward during its left-right swing. Specifically, when the guide block 41 moves along the first guide segment 32, the rack 21 moves leftward. When the guide block 41 moves along the second guide segment 33, the guide block 41 moves rightward. The guide block 41 moves leftward during its left-right swing.

[0050] like Figure 5 、 Figure 11 、 Figure 12As shown, the rack 21 moves leftward, causing the fixed frame 19 to rotate clockwise and the first end of the sliding frame 24 to rotate downward. The rack 21 moves rightward, causing the fixed frame 19 to rotate counterclockwise and the first end of the sliding frame 24 to rotate upward. As the rack 21 swings left and right, the first end of the sliding frame 24 swings up and down, causing the welding plate body 40 to vibrate up and down, helping to shake off weld slag on the welding plate body 40. The fixed frame 19 rotates clockwise as a whole during this swinging motion. As the fixed frame 19 moves from a horizontal to a vertical position, gravity causes the first end of the sliding frame 24 to move away from the fixed frame 19, gradually increasing the distance between the first end of the sliding frame 24 and the gear 20. The first end of the sliding frame 24 slides along the right inner wall of the retaining groove 39. The sliding frame 24 slides along the fixed frame 19, causing the sandpaper 25 to move along the weld seam on the welding plate body 40, polishing the weld seam and removing weld slag.

[0051] As fixed frame 19 moves from a vertical position to a horizontal position, the first end of sliding frame 24 moves along the left inner wall of retaining groove 39. Restricted by retaining groove 39, the first end of sliding frame 24 moves toward fixed frame 19. Simultaneously, sandpaper 25 moves along the weld seam on the first surface, polishing it. Weld slag falls into collection box 12.

[0052] like Figure 3 As shown, in order to prevent the bracket 23 from interfering with the movement of the lifting plate 5 and the guide plate 16, when the fixed frame 19 is in the initial state, the bracket 23 above the fixed frame 19 is in a vertical state, and the bracket 23 below the fixed frame 19 is tilted inward at a certain angle.

[0053] Until the fixing frame 19 is in a horizontal state, the second surface of the welding plate body 40 is facing upward and the first surface is facing downward. Then the bracket 23 above the fixing frame 19 is in a vertical state, and the bracket 23 below the fixing frame 19 is tilted inward at a certain angle.

[0054] Then the second surface of the welding plate body 40 can be welded.

[0055] By moving the guide plate 16, the welding plate body 40 can be turned over, making it easier to weld the second side of the welding plate body 40. In addition, welding slag can be cleaned during the turning process of the welding plate body 40, thereby improving work efficiency and facilitating subsequent weld inspection.

[0056] After the second side welding is completed, the driving assembly is started to turn the fixing frame 19 180 degrees again, so that the welding plate body 40 is turned 180 degrees, and the welding slag on the second side of the welding plate body 40 is cleaned.

[0057] Afterwards, the welded plate body 40 is removed from the mounting mechanism and placed on the slider 11 , with the weld being directly below the detector probe 9 , and then the weld is inspected using the detector probe 9 .

[0058] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
