[0002] Logistics robots are one of the essential facilities for advanced distribution centers. They have high work efficiency and are a key factor in improving logistics and distribution efficiency. Most existing warehouse logistics robots consist of robotic arms and robotic grippers. During sorting, the robotic arm moves to the corresponding position and the robotic gripper grasps the food.

[0003] However, existing robotic grippers have the following drawbacks: Currently, most robotic hands at the front end of robotic arms are fixedly installed. These robotic hands can only grip goods with similar shapes. For example, some robotic grippers can only grip and sort rectangular goods due to shape limitations, while others can only grip cylindrical objects. Therefore, the applicable scope of robotic hands is limited. When different types of goods need to be processed, it may be necessary to replace the robotic hand. The existing method for replacing robotic grippers is to loosen multiple nuts to release the fixed limit, then replace the gripper body with a different model and tighten the multiple nuts again to achieve fixation. However, since there are many fixing nuts, the replacement operation is cumbersome, time-consuming, and labor-intensive, reducing work efficiency and affecting the work process.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0025] Depend on Figures 1 to 5 The device includes a fixed block 1, with connecting blocks 2 slidably connected to the left and right sides of the fixed block 1. The fixed block 1 has a guide rod 3 located between the two connecting blocks 2 and capable of moving up and down. The lower end of the guide rod 3 has a rectangular block 4, and the front and rear ends of the rectangular block 4 have swing rods 5. The front swing rod 5 is hinged to the left connecting block 2, and the rear swing rod 5 is hinged to the right connecting block 2. The lower end of the connecting block 2 has a slot 6. The lower part of the connecting block 2 has a clamping plate 7 that can be inserted into the corresponding slot 6. The clamping plate 7 has limit holes 8 on the front and rear sides. The opposite ends of the two connecting blocks 2 have sliding grooves 9 that communicate with the slots 6. The sliding grooves 9 have movable blocks 10 that can move left and right. The movable blocks 10 have limit posts 11 on the front and rear sides that can be inserted into the limit holes 8 on the corresponding sides.

[0026] To enable the movable block 10 to slide, the movable block 10 is slidably connected to the connecting block 2. The upper end of the movable block 10 is provided with a triangular extrusion groove 12, and the opposite ends of the two connecting blocks 2 are respectively provided with a downward pressing groove 13 that communicates with the sliding groove 9. An L-shaped extrusion rod 14 is slidably connected in the downward pressing groove 13 and inserted into the extrusion groove 12.

[0027] For ease of use, the extrusion rod 14 can contact the inclined surface of the extrusion groove 12.

[0028] To facilitate the reset of the movable block 10, a reset groove 15 is provided in the connecting block 2, which is located below and communicates with the slide groove 9. A reset plate is provided at the lower end of the movable block 10, which is located in the reset groove 15. The reset plate is connected to the connecting block 2 via a spring 16.

[0029] To facilitate the movement of the extrusion rod 14, a push plate 17 is provided at the upper end of the extrusion rod 14.

[0030] To facilitate the movement of the guide rod 3, a cylinder 18 is provided at the upper end of the fixing block 1, and the output end of the cylinder 18 is fixedly connected to the guide rod 3.

[0031] To facilitate the movement of the two connecting blocks 2, the lower left and right sides of the fixed block 1 are respectively provided with guide posts 19 that are axially connected to the connecting blocks 2.

[0032] To facilitate the swing of the swing arm 5, a relief groove 20 is provided on the connecting block 2, and the swing arm 5 is located in the relief groove 20.

[0033] To facilitate clamping, the clamping plate 7 is provided with multiple silicone strips evenly distributed in the vertical direction.

[0034] When this utility model is in use, firstly, when it is necessary to clamp and sort items, the cylinder 18 is activated, which drives the guide rod 3 to move upward. The guide rod 3 drives the rectangular block 4 to move upward. The upward movement of the rectangular block 4 drives the two swing rods 5 to swing gradually, and drives the two connecting blocks 2 to move outward on the guide post 19. That is, the two connecting blocks 2 slide back to back. The connecting blocks 2 drive the clamping plate 7 to move outward, and the distance between the two clamping plates 7 gradually increases. Then, the cylinder 18 drives the guide rod 3 to move downward, and then the swing rods 5 drive the two connecting blocks 2 and the two clamping plates 7 to move towards the middle. After moving a certain distance, the object is clamped, thus completing the clamping operation.

[0035] When it is necessary to replace the clamping plate 7 with a different shape, first push the push plate 17 on the left connecting block 2 downward. The push plate 17 drives the pressing rod 14 to move downward. The lower end of the pressing rod 14 moves downward and contacts the inclined surface of the lower pressing groove 13, and drives the moving block 10 to slide to the left. The moving block 10 then drives the two limiting posts 11 to move to the left. After the limiting posts 11 move to the left a certain distance, they are pulled out from the limiting hole 8. At this time, the fixed limiting of the clamping plate 7 on the left is released. The clamping plate 7 on the left can then be pulled out from the slot 6. Then, the clamping plate 7 of a different shape that needs to be replaced is inserted into the slot 6, and the push plate 17 is released. Due to the restoring force of the spring 16, the moving block 10 is driven to move to the right by the reset plate. The moving block 10 drives the limiting post 11 to move to the right. After moving a certain distance, the limiting post 11 is inserted into the limiting hole 8 of the replacement clamping plate 7, thus achieving the fixed limiting of the new clamping plate 7.

[0036] Simultaneously, due to the reset of the moving block 10, the upward pressing rod 14 and the push plate 17 are moved to the initial position, at which point the replacement of the left clamping plate 7 is completed. The same operation is performed to release the fixed limit of the right clamping plate 7 and replace it with a new clamping plate 7.

[0037] Compared with the prior art, the beneficial effects of this utility model are: the connecting block, clamping plate, moving block, etc., can realize the quick and convenient replacement of different models of clamping plates, thereby realizing the clamping of different types of goods. Compared with the traditional replacement method, the operation is simple, time-saving and labor-saving, and improves work efficiency. This structure is simple, novel in concept, easy to use and highly practical.

[0038] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be split into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
