Description

Technical Field

[0001] The utility model belongs to the technical field of robots, and particularly relates to a collaborative robot safety device. Background Technique

[0002] With the continuous development of technology, mechanical equipment is used to replace manual labor in more and more places. For example, collaborative robots can control the automatic rotation or bending of the rotating arm to move workpieces.

[0003] When a collaborative robot is working, it generally adsorbs the workpiece on the tray through a suction cup and moves it to the next process. In this process, there are certain safety hazards. Once the on-site operator accidentally touches the workpiece, the workpiece is very likely to fall, causing injury to personnel. Summary of the Utility Model

[0004] In order to solve the above technical problems, the inventor developed a collaborative robot safety device based on rich experience accumulated in the technical field of robots.

[0005] The present application specifically adopts the following technical solutions to achieve the above object: A collaborative robot safety device, including a safety device, the safety device includes a suction cup mounting plate, a safety frame is sleeved outside the suction cup mounting plate, a proximity photoelectric is arranged in the middle section of the top of the suction cup mounting plate, a rope hook is arranged below the middle of the suction cup mounting plate, a screw is arranged at the lower left of the rope hook, the screw is connected to the frame of the mounting frame, iron plates are embedded at the bottoms of the left and right ends of the suction cup mounting plate, a magnet is arranged below the iron plate, the bottom of the magnet is attached to the safety frame, a suction cup is connected to the bottom of the suction cup mounting plate, a workpiece is adsorbed on the suction cup, and the safety device is installed on the top of the collaborative robot.

[0006] Further, the collaborative robot includes two rotating arms, and the rotating arms rotate 360° along the center of the arm axis. The two rotating arms can rotate 360°, which can effectively meet the on-site work needs.

[0007] Further, a base is arranged at the bottom of the collaborative robot, and a tray is connected to the right side of the base.

[0008] Further, the suction cup mounting plate adsorbs the workpiece on the tray through a suction cup.

[0009] Further, the length and width of the workpiece are smaller than the length and width of the safety frame.

[0010] Further, a soft rope is tied to the frame of the safety frame, and the other end of the soft rope is connected to a rope hook. The setting of the soft rope can prevent the safety frame from falling to the ground and also prevent the safety frame from hitting the on-site operators when it falls.

[0011] Compared with the prior art, the utility model has the following beneficial effects: By setting up devices such as materials, suction cups, suction cup mounting plates, screws, proximity photoelectric sensors, iron plates, magnets, and safety frames, this safety device can effectively prevent on-site operators from accidentally touching the workpiece and getting injured. Since the length and width of the safety frame are both larger than those of the suction cup mounting plate and also larger than the workpiece. In actual production, even if there is a situation where a person accidentally touches, it will first touch the mounting frame. Touching the safety frame will cause the safety frame to fall, so that the proximity photoelectric sensor cannot sense the screw, and the proximity photoelectric sensor will trigger an alarm. At this time, the collaborative robot will stop working, thus ensuring the safety of on-site operators. The safety frame is connected to the suction cup mounting plate by a soft rope, so it will not hit people, the ground or other objects. Thus, it effectively avoids the occurrence of personnel injuries. BRIEF DESCRIPTION OF THE DRAWINGS

For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] Refer to Figure 1 — Figure 4 As shown, a collaborative robot safety device includes a safety device 1. The safety device 1 includes a suction cup mounting plate 7. A safety frame 13 is sleeved outside the suction cup mounting plate 7. A proximity photoelectric sensor 9 is provided in the middle section of the top of the suction cup mounting plate 7. A rope hook 10 is provided below the middle of the suction cup mounting plate 7. A screw 8 is provided at the lower left of the rope hook 10, and the screw 8 is connected to the frame body of the mounting frame 13. Iron plates 11 are embedded at the bottoms of the left and right ends of the suction cup mounting plate 7. A magnet 12 is provided below the iron plates 11, and the bottom of the magnet 12 is attached to the safety frame 13. A suction cup 6 is connected to the bottom of the suction cup mounting plate 7, and a workpiece 5 is adsorbed on the suction cup 6. The safety device 1 is installed on the top of a collaborative robot 2.

[0021] In this embodiment, the collaborative robot 2 includes two rotating arms, and the rotating arms rotate 360° along the center of the arm axis. The two rotating arms can rotate 360°, which can effectively meet the working needs on site.

[0022] In this embodiment, a base 3 is provided at the bottom of the collaborative robot 1, and a tray 4 is connected to the right side of the base 3.

[0023] In this embodiment, the suction cup mounting plate 7 adsorbs the workpiece 5 on the tray 4 through the suction cup 6.

[0024] In this embodiment, the length and width of the workpiece 5 are smaller than the length and width of the safety frame 13.

[0025] In this embodiment, a soft rope is tied to the frame of the safety frame 13, and the other end of the soft rope is connected to the rope hook 10. The setting of the soft rope can prevent the safety frame 13 from falling to the ground and also prevent the safety frame 13 from hitting the on-site operators when it falls. Due to the limited space of the attached drawings, the soft rope is not marked in the attached drawings, but this does not affect the understanding of those skilled in the art of this application document.

[0026] When this safety device is in specific use, first check whether the appearance of the safety frame 13 is intact, and replace it in time if there is any damage. The on-site operator simulates the situation of accidentally touching the safety frame 13. When the on-site operator accidentally touches the safety frame 13, the safety frame 13 will fall. Since the screw 8 is installed on the safety frame 13, as the safety frame 13 falls, the proximity photoelectric sensor 9 cannot sense the screw 8, thereby triggering an alarm and the collaborative robot stops working. Thus, the safety of the on-site operators is effectively guaranteed. Since a soft rope is tied to the safety frame 1, it will not hit people, the ground or other objects.

[0027] When the collaborative robot 2 is working normally, as the rotating arm of the collaborative robot 2 rotates, the workpiece 5 on the tray 4 is adsorbed by the suction cup 6, and as the rotating arm rotates again, the workpiece 5 is moved to the next process.

[0028] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better illustrate the principles of the present utility model and its practical applications, and to enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.
