Description

Technical Field

[0001] The utility model relates to the technical field of suction cup grasping robots, in particular to a suction cup grasping robot with an anti-collision protection mechanism. Background Art

[0002] Suction cup gripper robots are highly efficient and flexible automated devices that utilize the negative pressure generated by suction cups to precisely grasp and carry objects on a variety of smooth, non-porous surfaces. Equipped with sophisticated control systems and sensors, these robots can accurately locate targets and adjust the force and position of the suction cups to accommodate objects of varying shapes, sizes, and weights. Whether used for parts handling in manufacturing, material handling on packaging lines, or cargo sorting and stacking in warehousing and logistics, suction cup gripper robots have demonstrated significant potential and high operational efficiency, significantly improving production efficiency and automation levels.

[0003] If the suction cup grasping robot does not have an anti-collision function during use, its significant disadvantage is that it cannot effectively avoid accidental contact with surrounding objects or people, which may cause damage to the equipment, increase safety hazards in the work area, and reduce production efficiency and the smoothness of the operation process. This lack of protection capability is particularly prominent in complex or dynamic working environments, limiting the application scope of the robot and increasing operational risks.

[0004] In order to solve the above problems, we have made improvements and proposed a suction cup grasping robot with an anti-collision protection mechanism. Utility Model Content

[0011] Compared with the prior art, the present invention provides a suction cup grasping robot with an anti-collision protection mechanism, which has the following beneficial effects:

[0012] 1.

The buffer rubber drives the buffer plate to move inward, and the buffer plate drives the movable plate to move inward through the connecting plate.

[0013] 2. The suction cup grasping robot with an anti-collision protection mechanism drives the movable sleeve to move inward through the connecting rod during the inward movement of the movable plate. The movable sleeve drives the second buffer spring to deform and squeeze inward, which can perform secondary buffering on the impact force generated by the collision, further improving the stability of the robot column during use. By providing the first slider and the first slide groove, the smoothness of the movable plate during movement can be effectively improved. By providing the second slide groove and the second slider, the stability of the connecting rod during up and down movement can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Through the above technical solution, the buffer rubber 5 is deformed by the influence of the force during the collision, so as to absorb the impact force generated by the collision. The buffer rubber 5 drives the buffer plate 4 to move inward, and the buffer plate 4 drives the movable plate 10 to move inward through the connecting plate 6.

In the process of the movable plate 10 moving inward, the connecting rod 14 drives the movable sleeve 13 to move inward, and the movable sleeve 13 drives the second buffer spring 12 to deform and squeeze inward, which can perform secondary buffering on the impact force generated by the collision, thereby further improving the stability of the robot column 2 during use.

[0023] Specifically, a second slide groove 17 is provided at the top and bottom of the inner side of the inner wall of the buffer box 3, a second slider 18 is fixedly connected to the inner side of the movable sleeve 13, and the inner side of the second slider 18 is slidably connected to the inner cavity of the second slide groove 17, the top and bottom of the movable plate 10 are fixedly connected to the first slider 15, a first slide groove 16 is provided at the top and bottom of the inner wall of the buffer box 3, and the outer side of the first slider 15 is slidably connected to the inner cavity of the first slide groove 16, the top of the robot column 2 is movably connected to the guide plate 19, and an electric push rod 20 is installed on the right side of the bottom of the guide plate 19, and a suction cup body 21 is provided at the bottom of the electric push rod 20.
