[0002] Industrial robots refer to machine devices used in the industrial field. The application of industrial robots can greatly improve work efficiency. Different industrial robots are used in different industrial production processes. For example, during transportation, industrial robots are used to grab goods and place them in another area.

[0003] Currently, the industrial robots used for cargo grabbing on the market cannot adjust the height of the device according to the scene when in use, and can only work on assembly lines at the same horizontal height, with poor applicability. The existing authorized patent is a cargo grabbing device for industrial robots, with patent announcement number CN202220218188.7. It starts the hydraulic push rod to drive the support rod to move upward and adjust, so that the support rod pushes the fixed block to squeeze the fixed spring, solving the problem of not being able to adjust the height. However, when the support rod needs to move downward, it is necessary to manually push and pull the handle to cancel the limit state of the support rod. Manual adjustment has a high risk factor and is also less efficient.

[0004] Therefore, we made improvements to this and proposed an adaptive adjustment type industrial robot grasping device. Summary of the Invention

[0025] The surface of the support column 5 is provided with a mounting plate 3 and a connecting plate 6, and a threaded rod 4 is provided between the mounting plate 3 and the connecting plate 6; when the threaded rod 4 rotates, the connecting plate 6 will move along the threaded rod 4, thereby adjusting the height of the connecting plate 6.

[0026] Two grab plates 11 are symmetrically and slidingly provided on the bottom surface of the connecting plate 6. A plurality of suction cups 12 are respectively installed on the opposite surfaces of the two grab plates 11. The goods can be adsorbed by the suction cups 12 to enhance stability. A through groove 23 is respectively opened on the two grab plates 11. A support plate 16 is slidingly provided in the through groove 23. When the suction cup 12 absorbs the goods, the bottom surface of the goods is located on the top of the support plate 16, and then the support plate 16 can support the bottom surface of the goods to prevent the goods from falling during the transportation process.

[0027] Protective frames 10 are mounted on opposite sides of the grabbing plates 11, and electric push rods 22 are mounted within the protective frames 10. The retractable ends of the push rods 22 are fixedly connected to one end of the support plate 16. When the push rods 22 retract and extend, they move the support plate 16, thereby adjusting its position. When grabbing cargo, the support plate 16 is positioned within the through slots 23. Once the cargo is attracted, the support plate 16 is moved to the bottom surface of the cargo.

[0028] A limit plate 19 is fixedly mounted within the mounting frame 1. The rotating shaft is rotatably connected to the bottom end of the limit plate 19. The top end of the support column 5 rotates through the limit plate 19 and the mounting frame 1, extending to the top of the mounting frame 1. A motor 3 20 is installed within the mounting frame 1.
