[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1-3This utility model provides an embodiment of an industrial robot gripping device, including a robotic arm 1. The robotic arm 1 is an automated mechanical device that simulates the movement function of a human arm, typically composed of multiple movable joints (such as rotary joints, sliding joints, etc.) and connecting rods. It can perform precise gripping, handling, assembly, welding, spraying, and other operations in three-dimensional space. A fixed plate 2 is fixedly connected to the movable end of the robotic arm 1. A motor 3 is fixedly connected to the inner wall of the fixed plate 2. The motor 3 is a device that converts electrical energy into mechanical energy. The above is prior art and will not be described in detail. A threaded rod 4 is fixedly connected to the output end of the motor 3. The threaded rod 4 is provided with two sets of reverse threads. By rotating the threaded rod 4, two sets of sliders 5 can be driven to move closer together or separate. A threaded sleeve is provided on the outer wall of the threaded rod 4. The threaded sleeve is provided with threads that match the threaded rod 4. A slider 5 is fixedly connected to the outer wall of the threaded sleeve. The outer wall of the slider 5 contacts a positioning block 10, which positions and clamps the object. A protrusion 11 is fixedly connected to the right side wall of the slider 5. An electric telescopic rod 6 is provided on the inner wall of the fixed plate 2. A support mechanism is provided at the movable end of the electric telescopic rod 6. A disassembly assembly is provided on the inner wall of the protrusion 11. The support mechanism includes a rectangular plate 7, which is fixedly connected to the movable end of the electric telescopic rod 6. A movable plate 8 is slidably connected to the outer wall of the rectangular plate 7. The movable plate 8 has a slot corresponding to the rectangular plate 7, allowing the movable plate 8 to move left and right. A hinge block 9 is hinged to the inner wall of the movable plate 8. Since the length of the hinge block 9 is fixed, when the movable plate 8 moves downward with one end of the hinge block 9, the other end of the hinge block 9 will flip inward. When the movable plate 8 moves upward with one end of the hinge block 9, the other end of the hinge block 9 will flip outward. A guide groove 14 is provided on the outer wall of the hinge block 9.

[0035] Reference Figure 1 , Figure 5 and Figure 6 The disassembly assembly includes a locking block 12, which is slidably connected to the inner wall of the protrusion 11. The protrusion 11 has a slot corresponding to the locking block 12, allowing the locking block 12 to move back and forth. The inner wall of the rear end of the locking block 12 is elastically connected to the protrusion 11 via a moving spring 13. When the locking block 12 moves backward, the moving spring 13 is compressed. When resetting, the elastic force of the moving spring 13 is used to reset the locking block 12. The locking block 12 is inserted into the inner wall of the positioning block 10, which has a slot corresponding to the locking block 12.

[0036] Reference Figures 2-4The threaded rod 4 is rotatably connected to the inner wall of the fixed plate 2. The fixed plate 2 has a slot corresponding to the smooth surface of the threaded rod 4 to facilitate the rotation of the threaded rod 4. The outer wall of the slider 5 is in contact with the inner wall of the fixed plate 2. The rectangular opening on the fixed plate 2 restricts the slider 5, so that the slider 5 can only move left and right. The fixed plate 2 has a rectangular opening inside. The right side of the slider 5 has a sliding groove. The movable plate 8 is inserted into the inner wall of the sliding groove. The sliding groove is vertically opened and guides the movable plate 8. A round rod is fixedly connected to the bottom front side of the positioning block 10. The round rod slides on the inner wall of the guide groove 14 and provides connection and support for the hinge block 9. The positioning block 10 is inserted into the outer wall of the protrusion block 11. The movable plate 8 is inserted into the inner wall of the positioning block 10. Two sets of rectangular blocks are set on the movable plate 8. Two sets of vertical slots corresponding to the rectangular blocks are opened on the positioning block 10.

[0037] Working principle: When it is necessary to grip and hold goods, the operator can manually turn on motor 3. Motor 3 will rotate threaded rod 4. The two sets of sliders 5 on threaded rod 4 will bring the positioning block 10, movable plate 8 and hinge block 9 together. After the positioning block 10 grips the goods, the goods are lifted by the externally controlled robotic arm 1. At this time, the externally controlled electric telescopic rod 6 moves downward. The electric telescopic rod 6 will move one end of rectangular plate 7, movable plate 8 and hinge block 9 downward. When the hinge block 9 moves downward, it will flip inward along the round rod on the positioning block 10. As the electric telescopic rod 6 moves downward, the hinge blocks 9 continuously flip inward to a horizontal state. At this point, the two sets of hinge blocks 9 contact the bottom of the goods, acting as a shield to prevent the goods from slipping. When it is necessary to lower the goods, the electric telescopic rod 6 is moved upward via external electric control. The electric telescopic rod 6 will move upward along with the rectangular plate 7, the movable plate 8, and one end of the hinge blocks 9. As one end of the hinge blocks 9 moves upward, the two sets of hinge blocks 9 will flip outward along the rod. When the electric telescopic rod 6 moves upward to its initial state, the hinge blocks 9 move to the position shown in the image. Figure 1 In the state shown, the hinge block 9 does not obstruct the bottom of the goods. Then, the motor 3 drives the threaded rod 4 to rotate, causing the two sets of sliders 5 to release the clamping and positioning of the goods along with the positioning block 10.

[0038] When it is necessary to remove the positioning block 10, manually move the locking block 12 backward. The locking block 12 will compress the moving spring 13. When the locking block 12 separates from the slot on the positioning block 10, manually remove the positioning block 10. Then manually release the locking block 12 and use the elastic force of the moving spring 13 to move the locking block 12 to the initial position. When it is necessary to install the positioning block 10, manually move the locking block 12 backward. When the locking block 12 no longer blocks the slot of the positioning block 10, manually align the positioning block 10 and insert it into the direction of the protrusion 11. Then manually release the locking block 12 to allow the locking block 12 to be inserted into the slot of the positioning block 10, thus completing the limiting of the positioning block 10.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
