[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1-5 A shelving frame welding auxiliary device includes a base 1 and a workbench 8, which are arranged in contact with each other. The bottom of the workbench 8 is provided with a base plate 11, and a fixed frame 14 is fixedly installed on the base plate 11. The top of the workbench 8 is provided with a movable groove 9 and an annular groove 10. A second sliding plate 15 and a first sliding plate 13 are slidably arranged in the movable groove 9 and the annular groove 10. A robotic arm 16 is installed on the first sliding plate 13, and a first welding gun 17 is provided at the end of the robotic arm 16. A second welding gun is fixedly installed on the second sliding plate 15. A second electric telescopic mechanism 18 is also provided at the bottom of the workbench 8. A movable block 28 is fixedly installed at the end of the second electric telescopic mechanism 18. A rotating rod 19 is rotatably arranged on the top of the movable block 28, and a support plate 20 is rotatably arranged on the rotating rod 19.
[0023] The frame 5, which is placed on the fixed frame 14, is supported by the support plate 20. The height of the support plate 20 is adjusted by the second electric telescopic machine 18, which facilitates welding of the frame 5 at higher positions.
[0024] The movable block 28 has an inner cavity 23. A dual-axis drive motor 24 is located at the top center of the inner cavity 23. The output shaft of the dual-axis drive motor 24 is connected to the rotating rod 19. An extension plate 25 is located below the dual-axis drive motor 24 in the inner cavity 23. A stop block 22 is slidably mounted on the extension plate 25. A cavity 21 is located in the middle of the support plate 20. The stop block 22 extends to the outside of the movable block 28, and the upper surface of the end of the stop block 22 away from the extension plate 25 abuts against the support plate 20. The lower surface of the stop block 22 has a slot 26. A locking block 27 is slidably mounted on the extension plate 25, and the locking block 27 is adapted to the slot 26.
[0025] Furthermore, a fourth electric telescopic mechanism is installed inside the inner cavity 23. The end of the fourth electric telescopic mechanism is fixedly connected to the abutment block 22. A height sensor is installed on the surface of the movable block 28. The height sensor is electrically connected to the fourth electric telescopic mechanism via a PLC programmable S4-400. When the second electric telescopic mechanism 18 moves the movable block 28 upward, the fourth electric telescopic mechanism moves the abutment block 22 backward, causing the abutment block 22 to separate from the pallet 20. The dual-axis drive motor 24 drives the pallet 20 to rotate, preventing the pallet 20 from colliding with the frame 5 above. An electric push rod is also installed on the extension plate 25. The electric push rod pushes the locking block 27, causing the locking block 27 to be embedded in the locking slot 26, thereby fixing the abutment block 22. When the pallet 20 contacts the frame 5, the abutment block 22 provides further support to the pallet 20, making the frame 5 more stable and facilitating processing operations.
[0026] A first drive motor 2 is provided on the base 1, a first electric telescopic mechanism 3 is provided at the end of the first drive motor 2, a horizontal plate 4 is sleeved on the end of the first electric telescopic mechanism 3, a vertical plate 7 is provided on the horizontal plate 4, a clamping plate 6 is slidably provided inside the vertical plate 7, and the frame 5 is held by the clamping plate 6.
[0027] Specifically, the frame 5 is assembled using clamping blocks 6 and horizontal plates 4. Workers move the frame 5 above the horizontal plates 4, push the clamping blocks 6 to move them above the frame 5 and make contact with the frame 5 to fix the frame 5. The first electric telescopic machine 3 drives the frame 5 to move up and down, and the first drive motor 2 drives the frame 5 to be transferred to the fixed frame 14 for alignment. Then, the first electric telescopic machine 3 moves the frame 5 to the height required for welding to facilitate the welding work.
[0028] It is worth noting that the vertical plate 7 can be replaced according to the height and thickness of the frame 5. The vertical plate 7 is connected to the horizontal plate 4 by threads, ensuring that the clamping plate 6 always contacts the upper surface of the frame 5. A rotating shaft is provided in the middle of the horizontal plate 4, and a third drive motor is provided at one end of the rotating shaft. The rotating shaft is controlled by the third drive motor to rotate, which facilitates the reset of the horizontal plate 4 after welding. After the clamping plate 6 is retracted, the rotating shaft is driven by the third drive motor to rotate, causing the horizontal plate 4 to bend and easily rotate to the outside for reset.
[0029] The robotic arm 16 has six degrees of freedom. It possesses three translational degrees of freedom and three rotational degrees of freedom. The robotic arm 16 can move freely and adjust its posture in three-dimensional space, facilitating welding operations at the frame joints using the first welding gun 17 at its end. The second welding gun, mounted on the second sliding plates 15 on both sides, can also achieve full-angle angle adjustment, further facilitating welding operations.
[0030] A second drive motor 12 is symmetrically arranged on the base plate 11. A connecting rod is provided on the output shaft of the second drive motor 12, extending into the annular groove 10 and fixedly connected to the first sliding plate 13. A third electric telescopic mechanism is provided in the movable groove 9, and the end of the third electric telescopic mechanism is fixedly connected to the second sliding plate 15. The second drive motor 12 drives the first sliding plate 13 to rotate in the annular groove 10, facilitating the adjustment of the position of the robotic arm 16. The third electric telescopic mechanism drives the second sliding plate 15 to slide in the movable groove 9, facilitating the movement of the first welding gun 17 by the robotic arm 16, enabling multi-angle adjustment for better welding operations. Adjusting the position of the second welding gun facilitates the welding operation.
[0031] Specifically, when welding is required for higher shelves, a fourth electric telescopic machine is installed on the first sliding plate 13 and the second sliding plate 15. The fourth electric telescopic machine is connected to the robotic arm 16 and the second welding gun respectively, which facilitates welding of the frame 5 at higher positions. At the same time, the second electric telescopic machine 18 is equipped with a multi-stage lifting output end, which is fixedly connected to the movable block 28.
[0032] Working principle: When using this device, the operator places the frame 5 on the horizontal plate 4. The bottom of the moving clamp 6 is brought into contact with the upper surface of the frame 5 to clamp and fix the frame 5. The first electric telescopic machine 3 drives the frame 5 to adjust its height. The first drive motor 2 drives the frame 5 to be transported above the fixed frame 14. The first electric telescopic machine 3 drives the frame to move along the fixed frame 14 to the required welding height. The second electric telescopic machine 18 drives the movable block 28 to move to the bottom of the frame 5. The support plate 20 lifts the frame 5, and the abutment block 22 supports the support plate 20 to prevent the frame 5 from shaking during welding. At the same time, the second drive motor 12 and the third electric telescopic machine drive the first sliding plate 13 and the second sliding plate 15 to move, which facilitates the welding operation of the first welding gun 17 and the second welding gun at the joint.
[0033] When welding the top frame 5 is required after welding the middle frame, the new frame 5 is clamped by the horizontal plate 4 and the clamping plate 6, and the frame 5 is moved to the fixed frame 14. The fourth electric telescopic machine drives the abutment block 22 to retract into the movable block 28. The dual-axis drive motor 24 drives the support plate 20 to rotate, so that the support plate 20 does not contact the surface of the frame 5. The second electric telescopic machine 18 drives the movable block 28 and the support plate 20 to move to the bottom of the top frame 5. The dual-axis drive motor 24 drives the support plate 20 to reset, which facilitates the support of the top frame 5, avoids the support plate 20 hitting the lower frame 5 and affecting the welding effect, and improves the service life of the support plate 20.
