DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 12As shown, the technical solution adopted by the present invention is as follows: a manufacturing robot welding and detection integrated workbench, including a support platform 1, a welding robot 38, a mounting mechanism and a detection mechanism. The mounting mechanism and the detection mechanism are both arranged on the support platform 1, the welding plate body 40 to be welded is arranged on the mounting mechanism, and the welding robot 38 welds the welding plate body 40. After welding is completed, the detection mechanism detects the weld.

[0022] The welding robot 38 is arranged above the support platform 1 and is arranged in cooperation with the mounting mechanism. A vertical plate 2 is fixedly mounted on one side of the support platform 1, and a lifting plate 5 is connected to the vertical plate 2 for vertical movement. Specifically, a first mounting groove is provided on the vertical plate 2, and a first threaded rod 3 is vertically and rotatably mounted in the first mounting groove. One end of the lifting plate 5 is limitedly and slidably arranged in the first mounting groove and is threadedly connected with the first threaded rod 3. A first motor 4 is fixedly mounted on the top of the vertical plate 2, and the motor shaft of the first motor 4 is fixedly connected with the first threaded rod 3. A second mounting groove is provided on the lifting plate 5, and a third threaded rod 34 is rotatably mounted in the second mounting groove. A second motor 6 that drives the third threaded rod 34 to rotate is fixedly mounted on the lifting plate 5. A slide 35 is limitedly and slidably mounted in the second mounting groove. The slide 35 is threadedly connected with 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, and a fifth motor 36 that drives the fourth threaded rod 37 to rotate is fixedly mounted on the slide 35, and the fixed block is threadedly connected with the fourth threaded rod 37. The welding robot 38 is mounted on the fixed block.

[0023] The mounting mechanism includes a support frame 13, a fixed frame 19 and a sliding frame 24. There are two support frames 13, and the two support frames 13 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 installed on the support platform 1, and a first electric push rod 27 is fixedly installed on the fixed plate 26, and the first electric push rod 27 is fixedly connected to the corresponding support frame 13. A guide rod 28 is fixed on the fixed plate 26, and the guide rod 28 is slidably connected to the corresponding support frame 13.

[0024] A fixing rod 18 is fixedly mounted on each support frame 13, and each fixing rod 18 is rotatably connected to a fixing frame 19. The middle portion of the fixing frame 19 is rotatably connected to the fixing rod 18. Each fixing frame 19 is limitedly slidably connected to a sliding frame 24. Figure 4 As shown, a second electric push rod 29 is fixedly arranged 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.

[0025] 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.

[0026] In this implementation, if Fig.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. Fig.11 , Fig.12 As shown, when the fixed frame 19 is in a horizontal state, both ends of the sliding frame 24 are in contact with the inner wall of the limiting groove 39. When the fixed frame 19 rotates to a vertical state, the fixed frame 19 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 gradually downward end of the sliding frame 24 slides along the inner wall of the limiting groove 39. When the fixed frame 19 moves from a vertical state to a horizontal state, one end of the sliding frame 24 slides along the inner wall of the limiting groove 39. Under the limit of the limiting groove 39, the end of the sliding frame 24 that contacts the inner wall of the limiting groove 39 gradually moves closer to the fixed frame 19 until the fixed frame 19 returns to a horizontal state, and both ends of the sliding frame 24 are in contact with 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, and then turns the welding plate body 40 over.

[0027] A bracket 23 is rotatably mounted on both the upper and lower sides of one of the fixed frames 19, and a sandpaper 25 is mounted on the bracket 23. A fourth motor 22 is fixedly mounted on the fixed frame 19 to drive the bracket 23 to rotate. The sandpaper 25 is closely attached to the weld on the welding plate body 40. When the fixed frame 19 rotates, the sliding frame 24 moves relative to the fixed frame 19, and the sandpaper 25 moves along the weld on the welding plate body 40 to grind the weld and clean the welding slag.

[0028] 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 limit rod 17 is fixedly installed on the support frame 13, and the rack 21 is limited and slidably set on the limit rod 17. The gear 20 is fixedly connected to the fixed frame 19, and the gear 20 is meshed with the rack 21. The rack 21 moves along the limit 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 in an up and down sliding manner. 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.

[0029] like Figure 5 , Figure 6As shown, a guide groove 31 is provided on the guide plate 16. The guide groove 31 is inclined. 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.

[0030] 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 direction close to the middle of the limit groove 39, the rack 21 moves to the left as a whole during the left and right swing.

[0031] A collecting box 12 is provided between two supporting frames 13 on the supporting platform 1. Welding slag dropped from the welding plate body 40 falls into the collecting box 12.

[0032] like Figure 1 , Figure 3 As 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 detection, 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.

[0033] Working principle: Initially, the fixed frame 19 is in a horizontal state. Both ends of the sliding frame 24 abut against the inner wall of the limiting groove 39. The guide block 41 is located at the upper end of the guide groove 31.

[0034] When in use, the two welding plate bodies 40 are respectively inserted into the two sliding frames 24, and the second electric push rod 29 is started to press the pressing plate 30 against the welding plate body 40, thereby fixing the welding plate body 40. Then, the first electric push rod 27 is started, and the first electric push rod 27 pushes the corresponding support frame 13 to slide, so that the two welding plate bodies 40 are connected.

[0035] After that, the first motor 4 is started to move the lifting plate 5 downward, thereby making the welding robot 38 close to the welding plate body 40. The fifth motor 36 is started to adjust the position of the welding robot 38 so that the welding robot 38 faces the joint between the two welding plate bodies 40. The second motor 6 and the welding robot 38 are started, and the welding robot 38 performs welding.

[0036] When the welding robot 38 completes welding on 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 on the first surface of the welding plate body 40.

[0037] The third motor 14 is started, and the guide plate 16 moves upward. The guide block 41 slides along the guide groove 31, and under the guidance of the guide groove 31, the rack 21 moves to the left while swinging left and right. Specifically, when the guide block 41 moves along the first guide section 32, the rack 21 moves to the left. When the guide block 41 moves along the second guide section 33, the guide block 41 moves to the right. And the guide block 41 moves to the left while swinging left and right.

[0038] like Figure 5 , Fig.11 , Fig.12 As shown, the rack 21 moves to the left, so that the fixed frame 19 rotates clockwise, and the first end of the sliding frame 24 rotates downward. The rack 21 moves to the right, the fixed frame 19 rotates counterclockwise, and the first end of the sliding frame 24 rotates upward. As the rack 21 swings left and right, the first end of the sliding frame 24 swings up and down, and the sliding frame 24 drives the welding plate body 40 to shake up and down, which helps to shake off the welding slag on the welding plate body 40. The fixed frame 19 rotates clockwise as a whole during the up and down swinging process. During the movement of the fixed frame 19 from the horizontal state to the vertical state, under the action of gravity, the first end of the sliding frame 24 moves away from the fixed frame 19, the distance between the first end of the sliding frame 24 and the gear 20 gradually increases, and the first end of the sliding frame 24 slides along the right inner wall of the limiting groove 39. The sliding frame 24 slides along the fixed frame 19, so that the sandpaper 25 moves along the weld on the welding plate body 40, and the sandpaper 25 grinds the weld and cleans the welding slag.

[0039] When the fixed frame 19 moves from the vertical state to the horizontal state, the first end of the sliding frame 24 moves along the left inner wall of the limiting groove 39. Under the limit of the limiting groove 39, the first end of the sliding frame 24 moves toward the fixed frame 19, and the sandpaper 25 moves along the weld on the first surface to grind the weld. The welding slag falls into the collection box 12.

[0040] 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.

[0041] 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.

[0042] Then the second surface of the welding plate body 40 can be welded.

[0043] By moving the guide plate 16, the welding plate body 40 can be turned over, which facilitates welding of the second side of the welding plate body 40. In addition, the welding slag can be cleaned during the turning over of the welding plate body 40, which improves the work efficiency and facilitates the subsequent detection of the weld.

[0044] After the second side welding is completed, the driving assembly is started to turn the fixing frame 19 over 180 degrees again, so that the welding plate body 40 is turned over 180 degrees, and the welding slag on the second side of the welding plate body 40 is cleaned.

[0045] Afterwards, the welded plate body 40 is removed from the mounting mechanism and placed on the slider 11 , with the weld being placed directly below the detector probe 9 , and then the weld is inspected using the detector probe 9 .

[0046] 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 protection scope of the present invention.
