Description

Technical Field

[0001] This invention relates to the field of robotic welding technology, and more particularly to a device for industrial robot-assisted welding. Background Technology

[0002] Industrial robot-assisted welding is a semi-automated welding process in which industrial welding robots are the core execution units and humans only perform auxiliary and non-core welding actions. It is also the most widely used mode in the industrial welding field. It is different from pure manual welding and fully automated unmanned welding. It entrusts the welding actions with high repetition, high labor intensity, high welding precision requirements and harm to the human body to robots, while leaving the auxiliary actions that require flexible judgment, flexible adjustment and low frequency and low intensity to humans.

[0003] Patent application number CN202411596023.3 describes in its specification that "This invention relates to the field of robotic welding technology, specifically an industrial robot-assisted welding device, comprising: a mounting base; a welding unit connected to the mounting base for multi-angle welding of a fixed workpiece; and a cyclic fixing unit disposed outside the welding unit and connected to the mounting base for independent support of multiple workpieces, and for automatically fixing and unbinding workpieces during workstation switching, achieving cyclic processing; wherein, the cyclic fixing unit includes: an inductive automatic fixing component, a self-locking drive control component, and an auxiliary cleaning component. By setting up the cyclic fixing unit, workpieces can be automatically fixed and automatically released from the constraints of the welded workpieces, facilitating loading and unloading operations. The entire processing process does not require manual fixing, reducing manual operation procedures and improving workpiece production efficiency."

[0004] While existing technologies offer the advantages mentioned above, they also have disadvantages: In current industrial robot welding systems, the workpiece is either manually clamped or held in place by a fixed fixture. Manual clamping is prone to loosening and workpiece shifting, while fixed fixtures cannot adapt to the downward pressure of the workpiece, requiring manual adjustment of the fixture's opening and closing, increasing the number of steps and reducing welding efficiency. Furthermore, when welding workpieces on both sides, the machine must be stopped manually to remove the workpiece, manually flip it, and then re-clamp it, leading to misalignment of the welding position after flipping, affecting the overall welding quality. Frequent manual contact with the welding station not only increases labor intensity but also poses safety hazards such as high temperatures and spatter. Therefore, there is an urgent need for an industrial robot-assisted welding device to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art where industrial robots weld workpieces, either by manually clamping and fixing the workpiece or by using fixed fixtures. Manual clamping is prone to loosening and workpiece displacement, while fixed fixtures cannot adapt to the downward pressure of the workpiece to complete the clamping, requiring manual adjustment of the fixture opening and closing, increasing the number of steps and reducing welding efficiency. In addition, when the workpiece needs to be welded on both sides, the machine must be stopped manually, the workpiece must be removed, manually flipped, and then re-clamped and fixed, which can lead to misalignment of the welding position after flipping, affecting the overall welding quality. Frequent manual contact with the welding station not only increases the labor intensity of workers, but also poses safety hazards such as high temperature and welding slag spatter.

[0052] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0053] 1. In use, the workpiece to be welded is placed on the lifting platform. Under the influence of gravity, the lifting platform descends, causing connecting block one, connecting block two, mounting plate, movable plate, moving rod, clamping plate, and anti-slip pad one to move vertically. At the same time, the elastic element is compressed and deformed. During the descent, the movable plate is affected by the limit rod and rotates on connecting block two, which in turn causes the moving rod, clamping plate, and anti-slip pad one to move towards the workpiece, ultimately clamping and fixing the workpiece. After the workpiece is removed, the elastic element and the helical spring return to their original positions. The entire process requires no manual adjustment of the clamping structure and no additional driving source, achieving adaptive clamping and fixing of the workpiece. At the same time, the anti-slip pad one further prevents the workpiece from sliding, which helps to improve the stability of the workpiece during the welding process and ensure welding accuracy.

[0054] 2. In use, the electric push rod is controlled to drive the lifting block, round rod, rotating plate, anti-slip pad II, and workpiece to move vertically, separating the workpiece from the lifting platform. Then, the drive motor is controlled to rotate, causing the round rod, rotating plate, anti-slip pad II, and workpiece to flip over, making it easier to adjust the unwelded side to the top. At this time, the drive motor stops working, the electric push rod places the workpiece on the lifting platform, the servo motor controls the moving frame to return to its original position, and controls electromagnets I and II to stop working. The lifting platform descends again, and the workpiece is clamped and fixed by the clamping plate again. This helps to improve the continuity of welding work, reduce the step of manually flipping the workpiece, and improve work efficiency.

[0055] 3. In use, this invention controls two transmission screws to rotate clockwise or counterclockwise, moving the two connecting blocks two, thereby controlling the position of the connecting blocks two on the lifting platform. This facilitates the application of workpieces of different sizes, improving the applicability range. At the same time, the use of universal balls, rotating wheels, and rotating rollers effectively reduces the contact area between the connecting blocks two and the lifting platform, reducing friction, improving the smoothness of the movement of the connecting blocks two, and thus extending their service life.

Detailed Implementation

[0066] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0067] Example 1, such as Figure 1 - Figure 8 As shown, the present invention provides a technical solution: an industrial robot-assisted welding device, comprising: a welding table 1 and a clamping assembly.

[0068] The clamping assembly includes two limiting posts 2, one end of each limiting post 2 is installed at both ends of the welding table 1, and the other end of each limiting post 2 is slidably connected to a connecting block 3. A lifting platform 4 is fixedly installed on the opposite side of the two connecting blocks 3. An elastic element 402 is fixedly connected to the outer surface of each connecting block 3. The other end of the elastic element 402 is fixedly connected to the outer surface of the welding table 1. The lifting platform 4 and the connecting block 3 are lifted to the top of the limiting post 2 by the elastic force of the elastic element 402.

[0069] It should be noted that two limiting rods 6 are fixedly connected to the outer surface of the welding table 1, and multiple movable plates 705 are slidably connected to the surface of the two limiting rods 6; two connecting blocks 7 are rotatably installed on the inner wall of the multiple movable plates 705, and mounting plates 701 are fixedly installed at both ends of the two connecting blocks 7; the movable plates 705 can rotate on the outer surface of the connecting blocks 7.

[0070] In addition, the inner walls of both sets of mounting plates 701 are slidably mounted with moving rods 702, and the outer surfaces of the two sets of moving rods 702 are movably connected to the outer surfaces of multiple moving plates 705 respectively. The outer surface of the welding table 1 is fixedly provided with a base 8. When the moving plate 705 rotates, it drives the moving rods 702 to move linearly.

[0071] As an example, in this embodiment, clamping plates 703 are fixedly installed on the outer surfaces of both sets of moving rods 702, and anti-slip pads 704 are fixedly provided on the outer surfaces of both sets of clamping plates 703. A welding robot 9 is fixedly installed on the outer surface of the base 8, and a welding head 10 is fixedly provided at one end of the welding robot 9. The welding robot 9 controls the welding head 10 to move. This is prior art and will not be described in detail here. When the moving rods 702 move, they drive the clamping plates 703 and anti-slip pads 704 to move linearly.

[0072] In this embodiment, the workpiece to be welded is placed on the lifting platform 4. Under the influence of gravity, the lifting platform 4 descends, causing the connecting block 3, connecting block 7, mounting plate 701, movable plate 705, moving rod 702, clamping plate 703, and anti-slip pad 704 to move vertically. At the same time, the elastic element 402 is compressed and deformed. During the descent, the movable plate 705 is affected by the limiting rod 6 and rotates on the connecting block 7, thereby causing the moving rod 702, clamping plate 703, and anti-slip pad 704 to move towards the workpiece, ultimately clamping and fixing the workpiece. This helps improve the stability of the workpiece in subsequent welding work. As a supplement, a helical spring can be fixedly installed at the end of the moving rod 702 away from the clamping plate 703, and the other end of the helical spring is fixed to the outer surface of the mounting plate 701, so that the workpiece can be removed from the lifting platform 4 after welding. After the lifting platform 4 is lifted by the elastic element 402, the moving rod 702, clamping plate 703, and anti-slip pad 704 are restored to their original positions by the helical spring.

[0073] Example 2, as Figure 1 - Figure 8 As shown, the present invention provides a technical solution: an industrial robot-assisted welding device, comprising: a transposition component.

[0074] It should be noted that the repositioning assembly includes: two movable frames 5, the outer surfaces of which are slidably mounted on the inner wall of the lifting platform 4, and the inner walls of the two movable frames 5 are threaded with a bidirectional threaded rod 501; the outer surfaces of the two movable frames 5 are each provided with a rectangular hole 508; multiple fixing blocks 509 are fixedly mounted at both ends of the lifting platform 4; the two ends of the bidirectional threaded rod 501 are mounted on the inner walls of two of the fixing blocks 509 via bearings; one end of the bidirectional threaded rod 501 is fixedly connected to a connecting block three 510; a worm gear 511 is fixedly connected to the outer surface of the connecting block three 510; when the worm gear 511 rotates, it drives the connecting block three 510 and the bidirectional threaded rod 501 to rotate, thereby driving the two movable frames 5 to move in a relative or opposite linear manner on the lifting platform 4;

[0075] As examples, in this embodiment, electric push rods 502 are fixedly installed on the outer surfaces of both movable frames 5, and lifting blocks 503 are fixedly connected to the output ends of both electric push rods 502; the outer surfaces of the two lifting blocks 503 are slidably connected to the inner walls of the two rectangular holes 508 respectively; round rods 504 are installed on the inner walls of the two lifting blocks 503 through bearings, and rotating plates 505 are fixedly provided at opposite ends of the two round rods 504; when the movable frame 5 moves laterally, it drives the rectangular holes 508, electric push rods 502, lifting blocks 503, round rods 504 and rotating plates 505 to move linearly; when the electric push rods 502 are working, their output ends drive the lifting blocks 503, round rods 504 and rotating plates 505 to move vertically.

[0076] In addition, anti-slip pads 506 are fixedly connected to the outer surfaces of both rotating plates 505. A drive motor 507 is fixedly installed on the outer surface of one of the lifting blocks 503. The output end of the drive motor 507 is fixedly installed at one end of one of the round rods 504. When the drive motor 507 is working, it drives the round rod 504 fixedly connected to its output end to rotate. When the round rod 504 rotates, it drives the rotating plate 505 fixedly connected to it to rotate.

[0077] The outer surface of the worm gear 511 is meshed with a worm 512. Both ends of the worm 512 are fitted with connecting blocks 4 513 through bearings. The outer surfaces of the two connecting blocks 4 513 are fixedly installed on the outer surface of the lifting platform 4. An electromagnet 1 403 is fixedly installed on the outer surface of the lifting platform 4. An electromagnet 2 404 is installed directly below the electromagnet 1 403. A connecting plate (405) is fixedly installed on the outer surface of the electromagnet 2 404. Both ends of the connecting plate (405) are fixedly installed on the outer surface of the welding table 1. A servo motor 514 is fixedly installed on the outer surface of the lifting platform 4. The output end of the servo motor 514 is fixedly installed at one end of the worm 512. When the servo motor 514 works, it drives the worm 512 and the worm gear 511 to move clockwise or counterclockwise. When the worm gear 511 rotates, it drives the connecting blocks 4 513 and the bidirectional threaded rod 501 to rotate.

[0078] In this embodiment, when the servo motor 514 is working, it drives the worm gear 512, the worm wheel 511 connecting block 4 513, and the bidirectional threaded rod 501 to rotate, thereby driving the two moving frames 5 to move relatively linearly on the lifting platform 4. This, in turn, drives the rectangular hole 508, the electric push rod 502, the lifting block 503, the round rod 504, the rotating plate 505, and the anti-slip pad 506 to move linearly, facilitating the clamping and fixing of the workpiece with one side welded using the two rotating plates 505 and the anti-slip pad 506. Subsequently, the electromagnets 403 and 404 are controlled to start working, and the two repel each other, facilitating the raising of the lifting platform 4 to contact the clamping plate 703 to clamp and fix the workpiece. Then, the output end of the electric push rod 502 is controlled to drive the lifting... Block 503, round rod 504, rotating plate 505, anti-slip pad 2 506, and workpiece move vertically, separating the workpiece from the lifting platform 4. Then, drive motor 507 is controlled to rotate, causing round rod 504, rotating plate 505, anti-slip pad 2 506, and workpiece to flip, making it easier to adjust the unwelded side to the top. At this time, drive motor 507 stops working, electric push rod 502 places workpiece on lifting platform 4, servo motor 514 controls moving frame 5 to return to its original position, controls electromagnet 1 403 and electromagnet 2 404 to stop working, lifting platform 4 descends again, and workpiece is clamped and fixed by clamping plate 703 again. This helps to improve the continuity of welding work, reduce the step of manually flipping workpiece, and improve work efficiency.

[0079] Example 3, as Figure 1 - Figure 8 As shown, the present invention provides a technical solution: an industrial robot-assisted welding device, comprising: an adapter component.

[0080] The adapter components include: a transmission hole 706, which is formed on the outer surface of one of the connecting blocks 7; a through hole 714 is formed on the outer surface of one of the connecting blocks 7; a transmission hole 707 is formed on the outer surface of the other connecting block 7; and a through hole 715 is formed on the outer surface of the other connecting block 7. A transmission screw 713 is threadedly connected to the inner wall of both the transmission hole 706 and the transmission hole 707. The outer surfaces of the two transmission screws 713 are slidably disposed on the inner walls of the through hole 714 and the through hole 715, respectively. When one of the transmission screws 713 rotates, it drives the transmission hole 706, one of the connecting blocks 7, and the through hole 714 to move linearly. The through hole 714 slides on the surface of the other transmission screw 713. When the other transmission screw 713 rotates, it drives the transmission hole 707, the other connecting block 7, and the through hole 715 to move linearly. The through hole 715 slides on the surface of one of the transmission screws 713.

[0081] It should be noted that two slide grooves 401 are opened on the outer surface of the lifting platform 4, and two sets of universal balls 708 are fixedly installed on the outer surface of the two connecting blocks 7. The balls of the two sets of universal balls 708 are slidably arranged on the inner wall of the two slide grooves 401 respectively. When the connecting block 7 moves, it drives the universal balls 708 to move linearly on the slide grooves 401, which makes it easier to reduce friction by using the balls of the universal balls 708.

[0082] In addition, each of the two connecting blocks 7 has an installation groove 709 on its outer surface. The inner walls of the two connecting blocks 7 are rotatably equipped with multiple rotating wheels 710. The outer surfaces of the two sets of rotating wheels 710 are respectively movably set on the inner walls of the two sliding grooves 401. When the connecting blocks 7 move, they drive the installation grooves 709 and rotating wheels 710 to move. When the rotating wheels 710 move, they rotate on the sliding grooves 401, which helps to reduce friction and extend service life.

[0083] As an example, in this embodiment, the outer surfaces of the two connecting blocks 7 are provided with multiple mounting holes 711, and the inner walls of the two sets of mounting holes 711 are rotatably connected to rotating rollers 712. The outer surfaces of the two sets of rotating rollers 712 are respectively movably connected to the inner walls of the two slide grooves 401. When the connecting block 7 moves, it drives the mounting holes 711 and rotating rollers 712 to move. When the rotating rollers 712 move, they rotate on the slide grooves 401, which helps to reduce friction and extend service life.

[0084] In this embodiment, by controlling the two transmission screws 713 to rotate clockwise or counterclockwise, the two connecting blocks 7 are moved, thereby controlling the position of the connecting blocks 7 on the lifting platform 4. This facilitates the application of workpieces of different sizes and improves the applicability. At the same time, by utilizing the universal ball 708, rotating wheel 710, and rotating roller 712, the contact area between the connecting blocks 7 and the lifting platform 4 is effectively reduced, which helps to reduce friction, improve the smoothness of the movement of the connecting blocks 7, and thus extend their service life.

[0085] Working Principle: When in use, an external power source is connected, and the two transmission screws 713 are controlled to rotate clockwise or counterclockwise, moving the two connecting blocks 7. This controls the position of the connecting blocks 7 on the lifting platform 4. The worker places the workpiece to be welded on the lifting platform 4. Due to gravity, the lifting platform 4 descends, causing the connecting blocks 3, 7, mounting plate 701, movable plate 705, moving rod 702, clamping plate 703, and anti-slip pad 704 to move vertically. Simultaneously, the elastic element 402 is compressed and deformed. During the descent, the movable plate 705 is affected by the limiting rod 6, causing the movable plate 705 to move on the connecting blocks 7. The rotation causes the moving rod 702, clamping plate 703, and anti-slip pad 704 to move towards the workpiece, ultimately clamping and fixing the workpiece. The welding robot 9 controls the welding head 10 to move, facilitating welding of the clamped and fixed workpiece. After the side directly above the workpiece is welded, the operator controls the servo motor 514 to rotate the worm gear 512, worm wheel 511, connecting block 4 513, and bidirectional threaded rod 501, thereby causing the two moving frames 5 to move relatively linearly on the lifting platform 4, which in turn moves the rectangular hole 508. The electric push rod 502, lifting block 503, round rod 504, rotating plate 505, and anti-slip pad 506 move linearly, facilitating the clamping and fixing of a workpiece welded on one side using the two rotating plates 505 and the anti-slip pad 506. Then, the electromagnets 403 and 404 are controlled to work, repelling each other and raising the lifting platform 4 to contact the clamping plate 703 for workpiece clamping and fixing. The output end of the electric push rod 502 then drives the lifting block 503, round rod 504, rotating plate 505, and anti-slip pad 506 to move linearly. The workpiece moves vertically, separating it from the lifting platform 4. Then, the drive motor 507 rotates, causing the round rod 504, rotating plate 505, anti-slip pad 506, and workpiece to flip, making it easier to adjust the unwelded side to the top. At this time, the drive motor 507 stops working, the electric push rod 502 places the workpiece on the lifting platform 4, the servo motor 514 controls the moving frame 5 to return to its original position, and controls the electromagnets 403 and 404 to stop working. The lifting platform 4 descends again, and the workpiece is clamped and fixed by the clamping plate 703 again.
