[0002] A robotic arm is a mechanical device that can mimic the movements of a human arm and perform automated operations according to a preset program or artificial intelligence instructions. Among them, the visual positioning device is a machine vision system based on image analysis. Its main function is to accurately obtain the coordinate position and angle of the object to be grasped or assembled, and convert the image coordinates into robot coordinates that the robotic arm can recognize, so as to guide the robotic arm to perform precise operations.

[0003] The visual positioning devices currently used in robotic arms have the following problems when applied:

[0004] 1. Traditional vision positioning devices for robotic arms are typically fixed in place by fasteners, and their height is not adjustable. When it is found that the vision of the robotic arm is limited by the height and the whole picture cannot be clearly seen, it is necessary to replace the device body. Therefore, it does not have a height-adjustable structure when in use.

[0005] 2. When most robotic arms use vision positioning devices, when idle, fine dust particles in the air will directly cover the outside of the monitoring structure. However, in order not to affect the clarity of vision, the staff needs to clean it regularly. Therefore, when idle, there is no dustproof structure installed on the outside. Utility Model Content

[0006] The purpose of this invention is to provide a visual positioning device for robotic arms to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the specific technical solution of this utility model is as follows: A visual positioning device for a robotic arm includes a device body and a base plate.

[0028] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a visual positioning device for a robotic arm.

[0029] like Figure 1-5As shown, a visual positioning device for a robotic arm according to this utility model includes a device body 1 and a base plate 2. The bottom of the device body 1 is provided with the base plate 2, and the top of the base plate 2 is provided with a guide rod 6. A square frame 13 is sleeved on the outside of the guide rod 6, and a threaded rod 14 is provided inside the square frame 13. A fixing rod 9 is provided on the top of the device body 1, and a fixing ring 10 is sleeved on the outside of the fixing rod 9. A horizontal plate 12 is provided on the side of the fixing ring 10. The installation of the horizontal plate 12 facilitates the fixed connection between the fixing ring 10 and the square frame 13. The side of the horizontal plate 12 is connected to the square frame 13. A gasket 16 is sleeved on the outside of the threaded rod 14. The external threaded connection of 14 is used to install nut 15. The guide rods 6 are symmetrically distributed. The top of the guide rod 6 is provided with a limiting block 7. By installing the guide rod 6 and the limiting block 7 on the top of the base plate 2, and installing the fixing rod 9 and the fixing ring 10 on the top of the device body 1, the square frame 13 and the threaded rod 14 are connected to the side of the fixing ring 10. When the robotic arm finds that the line of sight is obstructed during the data acquisition process, the operator first reverses the fasteners to move the square frame 13 upward outside the guide rod 6. After it is moved to a suitable height, the external fasteners are tightened again to fix it. This adjustment operation is simple.

[0030] The device body 1 has a frame 18 on its side, with a dustproof net 19 inlaid on the side of the frame 18. A notch 20 is opened on the outer side of the frame 18, and a shaft 25 is inlaid inside the notch 20. The first plate 21 is sleeved on the outside of the shaft 25. The bottom of the first plate 21 is connected to the second plate 22 through a pivot. A metal sheet 23 is provided on the side of the first plate 21, and a magnetic suction sheet 24 is provided on the outside of the second plate 22. The magnetic suction sheet 24 magnetically attracts the metal sheet 23. By providing an irregular plate 17 and a frame 18 on the outside of the device body 1, and installing the first plate 21 and the second plate 22 on the outside of the frame 18, and inlaying the dustproof net 19 on the side of the frame 18, when the device body 1 is idle, the operator can rotate the first plate 21 and the second plate 22 in the opposite direction to flip the plate structure to the outside of the monitoring structure. The dustproof effect is strong when the device body 1 is idle.

[0031] An arc-shaped groove 8 is opened inside the guide rod 6, and a threaded rod 14 is embedded inside the arc-shaped groove 8. The side of the fixing ring 10 is connected to the connecting plate 11. By opening the arc-shaped groove 8, the threaded rod 14 inside the square frame 13 can move quickly inside the guide rod 6.

[0032] The base plate 2 has a mounting plate 3 on its side, and a mounting hole 4 is opened on the top of the mounting plate 3. A fastening screw 5 is embedded in the mounting hole 4. Because of the fastening screw 5, it is convenient to install and fix the base plate 2 to the outside of the robotic arm.

[0033] The top of the frame 18 is provided with a fixing frame 26, and the side of the fixing frame 26 is provided with an elastic plate 27. The elastic plates 27 are symmetrically distributed, and the outer side of the elastic plate 27 is provided with a limiting plate 28. By installing the elastic plate 27 and the limiting plate 28, it is convenient to limit and fix the first plate 21 and the second plate 22 when they are idle.

[0034] The device body 1 has an irregularly shaped plate 17 on its side, and the frame 18 is connected to the outside of the irregularly shaped plate 17. The installation of the irregularly shaped plate 17 makes it convenient to connect and fix the frame 18 and the device body 1.

[0035] The working principle of the vision positioning device used in this robotic arm is as follows: When using the device body 1, it is first necessary to move the device body 1 to a suitable position. Then, the fastening screw 5 is removed and passed through the mounting hole 4 to connect and fix the base plate 2 to the mounting surface. However, in order to facilitate the vertical movement of the device body 1, a guide rod 6 and a limiting block 7 are installed on the top of the base plate 2, and a fixing rod 9 and a fixing ring 10 are installed on the top of the device body 1. A square frame 13 is connected to the side of the fixing ring 10 through a horizontal plate 12, and a threaded rod 14 is installed inside the square frame 13. When the robotic arm finds that the line of sight is obstructed while collecting data, the operator first reverses the fasteners to move the square frame 13 upward outside the guide rod 6. After moving to a suitable height, the external mounting nut 15 is tightened again to fix it. In this way, the device body 1 has a height-adjustable structure, and the position of the device body 1 can be adjusted in time according to the needs of the operator. Moreover, the adjustment operation is simple. When the device is in use, in order to prevent dust from entering the monitoring structure on the outside of the device body 1, a shaped plate 17 and a frame 18 are provided on the outside of the device body 1, and a first plate 21 and a second plate 22 are installed on the outside of the frame 18. The side of the first plate 21 is provided with a metal sheet 23, and the outside of the second plate 22 is provided with a magnetic suction sheet 24. A dustproof net 19 is embedded in the side of the frame 18. When the device body 1 is not in use, the elastic plate 27 on the side of the fixing frame 26 is fastened to move the limiting plate 28 outward. The operator moves the plate to the side, then rotates the first plate 21 and the second plate 22 outwards to flip the plate structure to the outside of the monitoring structure. This provides a stronger dustproof effect when idle. Finally, when the device body 1 needs to be used, the operator first rotates the second plate 22 to magnetically attract the metal sheet 23 to the magnetic plate 24, and then rotates the first plate 21 and the second plate 22 in the opposite direction to snap the limiting plate 28 on the inner side of the elastic plate 27 to limit the position. In this way, the device body 1 can be used normally.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
