Description

Technical Field

[0001] The utility model relates to the field of stamping robot suction cups, in particular to a stamping robot suction cup device. Background Art

[0002] Stamping robots are automated industrial robots specially configured for various punching machines and hydraulic presses. They are designed to efficiently replace manual stamping operations and realize automatic loading and unloading. They have multiple degrees of freedom, including flexible vertical lifting, horizontal rotation, horizontal axis extension and retraction, workpiece rotation and workpiece flipping, etc. They can automatically adapt to the punching machine height, feeding height and unloading height, thereby meeting the process requirements of various stamping products to the greatest extent.

[0003] The suction cup of a stamping robot is one of the commonly used clamping tools of the robot. It achieves the functions of fixing and carrying by adsorbing on the surface of the workpiece. The working principle of the suction cup is mainly based on the negative pressure principle, that is, a vacuum pump or pressure source is used to generate negative pressure, so that a pressure difference is formed between the suction cup and the surface of the adsorbed object, thereby generating adsorption force. The staff determines the predetermined position of the suction cup according to the size, shape and grasping requirements of the workpiece, and uses a hexagonal wrench to tighten the hexagonal screw on the suction cup to complete the fixation.

[0004] However, the existing stamping robot suction cup device usually has a fixed structure. When it is necessary to suck asymmetric parts, it is not convenient to adjust the suction cup position, which is very inconvenient to use. Therefore, it is necessary to modify the existing stamping robot suction cup device. Utility Model Content

[0007] By adopting the above technical solution, the number of working steps for adjusting the suction cup position is reduced, the work efficiency is improved, and the overall stability of the stamping robot suction cup device is improved, so that the suction cup can flexibly adapt to different working environments, effectively avoiding the problem of position changes caused by misoperation or external interference.

[0008] Furthermore, a plurality of groups of suction cup brackets are symmetrically installed on the outer wall of the device body, and two groups of suction cup seats are symmetrically installed on the outer wall of the bidirectional screw rod.

[0009] By adopting the above technical solution, it is beneficial to improve the overall stability of the stamping robot suction cup device, so that the suction cup can flexibly adapt to different working environments.

[0010] Furthermore, the suction cup seat is designed to be rectangular and closely attached to the inner wall of the suction cup bracket, and the length of the movable groove is smaller than that of the suction cup bracket.

[0011] By adopting the above technical solution, the suction cup seat will only move linearly with the rotation of the bidirectional screw rod, and will not rotate with the bidirectional screw rod.

[0012] Furthermore, a sliding groove with a circular cross-section is provided at the end of the bidirectional screw rod, and the sliding block is designed in a "mouth" shape.

[0013] By adopting the above technical solution, the sliding block can slide freely on the end of the bidirectional screw rod without affecting the rotation of the handle.

[0014] Furthermore, the outer wall of the handle is designed to be an arc, and the end portion where the handle is connected to the sliding block is designed to be spherical.

[0015] By adopting the above technical solution, the handle is facilitated to slide along with the sliding block without affecting the rotation of the handle on the outer wall of the sliding block.

[0016] Furthermore, a plurality of second fixing grooves are provided on the outer wall of the rotating disk at equal angles, and the second fixing grooves are designed to be arcs corresponding to the handles.

[0017] By adopting the above technical solution, the handle and the second fixing groove are closely matched, so that the rotation of the bidirectional screw rod can be controlled by the handle.

[0018] Furthermore, after the handle is rotated to the first fixing groove, the end of the handle is higher than the plane of the outer wall of the suction cup bracket.

[0019] By adopting the above technical solution, it is beneficial for the staff to easily release the limit of the handle after the handle is limited in position.

[0020] In summary, the present invention has the following beneficial effects:

[0021] The utility model is provided with a bidirectional screw rod and a suction cup seat, so that when the position of the suction cup needs to be adjusted, it is only necessary to twist the bidirectional screw rod, which reduces the work steps and improves the work efficiency. By providing a rotating disk, a second fixed slot and a handle, the angle of the handle can be controlled. The handle cooperates with the second fixed slot provided on the rotating disk to rotate the bidirectional screw rod to drive the suction cup seat to adjust the position, thereby ensuring the accuracy and stability of the adjustment. By providing a sliding slot and a sliding block, the handle can be rotated to the position of the first fixed slot through the sliding slot after the position adjustment of the suction cup seat is completed. By providing the first fixed slot, the position of the handle is limited, so that the bidirectional screw rod will not rotate at will, and the problem of position change caused by misoperation or external interference is effectively avoided.

A sliding groove 21 is provided at the end of the two-way screw rod 2, and a sliding block 31 is slidably installed on the inner wall of the sliding groove 21. The sliding block 31 slides freely at the end of the two-way screw rod 2 and slides A handle 3 is rotatably installed on the outer wall of the block 31, and the handle 3 can rotate on the "mouth"-shaped outer wall of the sliding block 31. A rotating disk 22 is installed on the end of the bidirectional screw rod 2, and a second fixed groove 23 corresponding to the handle 3 is provided on the outer wall of the rotating disk 22. The handle 3 and the second fixed groove 23 fit tightly together, so that the rotation of the bidirectional screw rod 2 can be controlled by the handle 3, and a first fixed groove 12 corresponding to the handle 3 is provided on the outer wall of the suction cup bracket 11. After completing the required position adjustment, the handle 3 enters the inner wall of the first fixed groove 12, ensuring that the bidirectional screw rod 2 can remain stable when no position adjustment is required, avoiding position changes due to misoperation or external interference.

[0030] See also Figure 1 Multiple sets of suction cup brackets 11 are symmetrically installed on the outer wall of the device body 1, and two sets of suction cup seats 13 are symmetrically installed on the outer wall of the bidirectional screw rod 2, which is beneficial to improving the overall stability of the stamping robot suction cup device and allowing the suction cup to flexibly adapt to different working environments.

[0031] See also Figure 1 - Figure 4 The suction cup seat 13 is a rectangular design that is close to the inner wall of the suction cup bracket 11, and the length of the movable groove 14 is smaller than the suction cup bracket 11, so that the suction cup seat 13 will only move linearly with the rotation of the bidirectional screw rod 2, and will not rotate with the bidirectional screw rod 2.

[0032] See also Figure 4 A sliding groove 21 with a circular cross-section is provided at the end of the bidirectional screw rod 2, and the sliding block 31 is designed in a "mouth" shape, so that the sliding block 31 can slide freely at the end of the bidirectional screw rod 2 without affecting the rotation of the handle 3.

[0033] See also Figure 1 - Figure 4 The outer wall of the handle 3 is designed as an arc, and the end portion where the handle 3 is connected to the sliding block 31 is designed as a spherical shape, which is conducive to the handle 3 sliding with the sliding block 31 without affecting the rotation of the handle 3 on the outer wall of the sliding block 31.

[0034] See also Figure 1 - Figure 3The outer wall of the rotating disk 22 is provided with multiple sets of second fixed grooves 23 at equal angles, and the second fixed grooves 23 are designed in an arc shape corresponding to the handle 3, which is conducive to the close fit between the handle 3 and the second fixed grooves 23, so that the rotation of the bidirectional screw rod 2 can be controlled by the handle 3.

[0035] See also Figure 1 - Figure 4 After the handle 3 is rotated to the first fixing groove 12, the end of the handle 3 is higher than the outer wall plane of the suction cup bracket 11, which is conducive to the staff being able to easily release the limit of the handle 3 after the handle 3 is limited to a position.

[0036] The working principle of the present invention is as follows: when it is necessary to adjust the suction cup position of the stamping robot suction cup device, the handle 3 is first rotated along the outer wall of the sliding block 31, so that the rotating handle 3 is disengaged from the limit of the first fixed groove 12, and the handle 3 follows the sliding block 31 to slide freely on the inner wall of the sliding groove 21. Then, the handle 3 is rotated to enter the second fixed groove 23 opened on the outer wall of the rotating disk 22, and the handle 3 and the second fixed groove 23 are tightly matched to ensure the stability and accuracy of the rotation. At this time, shaking the handle 3 will drive the bidirectional screw rod 2 to rotate, so that the multiple groups of suction cup seats 13 installed on the outer wall of the bidirectional screw rod 2 start to move symmetrically, adjust the suction cup position, and after completing the required position adjustment, the handle 3 is rotated to disengage from the limit of the second fixed groove 23, and the handle 3 follows the sliding block 31 to slide freely to the position of the first fixed groove 12, and the handle 3 enters the inner wall of the first fixed groove 12, ensuring that the bidirectional screw rod 2 can remain stable when no position adjustment is required, avoiding position changes caused by misoperation or external interference.
