AI Technical Summary
In automated logistics systems, vibrations and gaps between bins can cause bin lids to stick together. Existing visual guidance methods cannot completely prevent the lower bin lids from being lifted, which affects the smoothness of destacking operations and is costly.
The system uses clamping components to hold the boxes together and positioning components to hold down the lower box lid. The robotic arm then separates the upper box from the lower box, achieving a highly efficient and precise destacking process.
It improves the efficiency and accuracy of the destacking process, avoids the lower box lid being lifted, and reduces system costs.

[0046] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
[0047] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the present application provides a kind of to disengage device, including manipulator and mechanical claw clamp, mechanical claw clamp is driven under the manipulator and is split to the box body stacked together;The mechanical claw clamp includes: mounting seat 1, mounting frame 2, clamping assembly 3, positioning assembly 4 and controller 5.Mounting seat 1 is used to connect with manipulator.Mounting frame 2 is connected with the bottom of mounting seat 1.Clamping assembly 3 is installed at the bottom of mounting frame 2.Positioning assembly 4 is installed on clamping assembly 3.Controller 5 is electrically connected with clamping assembly 3 and positioning assembly 4.
[0048] When the unstacking is performed, the manipulator drives the unstacking device to descend, and after descending to a specified position, the clamping assembly 3 clamps the box to be unstacked. Then the positioning assembly 4 extends outward to press the upper box cover of the lower layer, and the manipulator drives the mechanical gripper to ascend to separate the upper box from the lower box.
[0049] More specifically, the positioning assembly 4 includes a driving member 41 and a telescopic member 42. The driving member 41 is installed on the mounting frame 2. The telescopic member 42 is installed on the clamping assembly 3, and the driving member 41 communicates with the telescopic member 42.
[0050] When the unstacking is performed, the controller 5 controls the driving member 41 to drive the telescopic member 42 to move outward to press the upper box cover of the lower layer, so that the clamping assembly 3 does not lift the lower box cover when unstacking.
[0051] It should be noted that the driving member 41 is a gas pump, and the telescopic member 42 is a gas cylinder. In other embodiments, the positioning assembly 4 can also be a linear motor or other mechanical structure that can realize linear motion.
[0052] In one embodiment, as shown in Figure 1 , the mounting frame 2 is provided with a sliding groove 21, and the clamping assembly 3 is installed in the sliding groove 21. In order to facilitate the sliding of the clamping assembly 3, the mounting frame 2 is provided with the sliding groove 21.
[0053] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , the clamping assembly 3 includes a clamping rod 31, a clamping cylinder 32, and a clamping plate 33. The clamping rod 31 has at least two opposite clamping rods arranged in the sliding groove 21. The clamping cylinder 32 is installed at the bottom of the mounting frame 2, and the movable end of the clamping cylinder 32 is connected with the clamping rod 31. The clamping plate 33 is installed on the clamping rod 31, and the clamping plate 33 is installed perpendicular to the axis direction of the clamping rod 31. The positioning assembly 4 is installed on the clamping plate 33.
[0054] When the box needs to be clamped, the clamping cylinder 32 drives the clamping rod 31 to move, so that the clamping plate 33 installed on the clamping rod 31 contacts the box. When the clamping plate 33 clamps the box, the manipulator drives the mechanical gripper to ascend.
[0055] In one embodiment, as shown in Figure 1 , when the clamping rod 31 is slidably installed in the sliding groove 21, the clamping cylinder 32 is a double-head cylinder, and the clamping cylinder 32 drives the clamping rod 31 to move away from each other or to move relative to each other.
[0056] In order to facilitate the movement of the two clamping rods 31, the clamping cylinder 32 is a double-end cylinder, and the movable end of the double-end cylinder drives the clamping rod 31 to clamp the box.
[0057] In one embodiment, as shown in Figure 1 and Figure 3 , the clamping assembly 3 further comprises two sliding blocks 34. The two sliding blocks 34 are matched with the sliding groove 21 and located at the two ends of the clamping cylinder 32 and connected with the movable end of the clamping cylinder 32. Two clamping rods 31 are arranged on each of the two sliding blocks 34.
[0058] In order to facilitate the stable movement of the clamping rod 31 driven by the clamping cylinder 32, a sliding block 34 is arranged on the sliding groove 21, and the clamping rod 31 is installed on the sliding block 34. When it is needed to clamp the box or release the box, the clamping cylinder 32 drives the sliding block 34 to slide in the sliding groove 21.
[0059] The cooperation of the sliding groove 21 and the sliding block 34 can further improve the stability of the clamping assembly 3 and avoid shaking or deviation during clamping.
[0060] In one embodiment, as shown in Figure 1 and Figure 2 , the clamping assembly 3 further comprises an anti-skid rubber block 35. The anti-skid rubber block 35 is installed on the clamping plate 33, and the anti-skid rubber block 35 is installed towards the box.
[0061] In order to avoid the box from sliding during unstacking, the anti-skid rubber block 35 is arranged on the clamping plate 33.
[0062] In another embodiment, as shown in Figure 1 and Figure 2 , in order to further improve the anti-skid performance of the anti-skid rubber pad, an anti-skid pattern 36 is arranged on the side wall of the anti-skid rubber pad.
[0063] In one embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , the positioning assembly 4 further comprises a top plate 43. The top plate 43 is installed at the end of the movable end of the telescopic member 42.
[0064] In order to avoid leaving marks on the box cover when pressing the box cover of the lower layer, a top plate 43 is arranged at the end of the movable end of the telescopic member 42.
[0065] Specific working principle:
[0066] The controller 5 controls the robot to drive the mechanical gripper to descend to a proper position, and then controls the clamping cylinder 32 to move, and the clamping cylinder 32 drives the clamping rod 31 to move relatively during the movement, so that the clamping plate 33 installed on the clamping rod 31 is in contact with the box body. Then the controller 5 controls the driving member 41 to drive the telescopic member 42 to move downward, so that the top plate 43 installed on the telescopic member 42 is in abutment with the box cover of the next layer. When the controller 5 controls the robot to move upward, the top plate 43 on the telescopic member 42 presses the box cover, so that the box cover of the lower layer is prevented from being lifted by the upper layer of the box body.
[0067] In another embodiment, the controller 5 controls the robot to lift the mechanical gripper, and after the mechanical gripper is lifted to a specified distance, the controller 5 controls the driving member 41 to provide driving force for the telescopic member 42, and the telescopic member 42 extends outward to knock the box cover of the next layer from the bottom of the upper layer of the box body.
[0068] In another embodiment, the controller 5 controls the robot to move upward, and the controller 5 controls the telescopic member 42 to extend outward (the moving direction of the robot and the moving direction of the telescopic member 42 are opposite), so that the box cover of the lower layer is prevented from being lifted by the upper layer of the box body during the movement of the upper layer of the box body.
[0069] Finally, it should be noted that the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some of the technical features. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
