[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the present invention, by providing a movable rod and an abutment block, the movable rod can complete the clamping of the logistics box, thereby realizing the automatic picking of the logistics box on the shelf, increasing the convenience of using the device and reducing the labor intensity of the staff. The abutment block squeezes the outer side of the logistics box. When the squeezing force reaches a preset value, the state of the logistics box is photographed by the camera on the connecting rod and transmitted to the background control system for graphic comparison, so that the change of the logistics box under the standard pressure can be detected, so as to complete the detection of the anti-squeezing force of the logistics box itself;

[0018] After the logistics box on the mounting plate is loaded, the movable rod rises to the height of the top logistics box on the mounting plate. By moving the movable rods closer to each other, the movable rods can enclose the logistics box on the mounting plate, thereby fixing the logistics box and increasing the placement stability of the logistics box during transportation.

[0019] In the present invention, a movable plate is provided. When the logistics box is placed on the movable plate, during the movement of the mounting plate, when the mounting plate moves on the ground and vibrates, the vibration will be transmitted to the movable plate, so that the movable plate slides inside the first slot, and the first spring telescopic rod absorbs and weakens the sliding force of the movable plate.

[0020] When the logistics boxes are stacked on the movable plate, the weight of the logistics boxes presses the movable plate downward, causing the first spring telescopic rod abutting against the first pressure sensor to squeeze the first pressure sensor. The first pressure sensor transmits the measured pressure value to the background control system, and the background control system compares the measured pressure value with the standard pressure value. Through this operation method, the weight of the logistics boxes on the mounting plate can be detected to prevent the weight of the logistics boxes from exceeding the bearing limit of the mounting plate, thereby increasing the safety of the device and extending the service life of the device.

[0042] As a technical optimization solution of the present invention, the cleaning mechanism includes a roller brush 20, and the movable rod 7 is provided with a second slot 19 on the side away from the third slot 24. The roller brush 20 is rotatably installed inside the second slot 19. The second slot 19 is embedded with a second rotating motor 23 on the inner wall of the end away from the lifting rod 6. The output end of the second rotating motor 23 faces the roller brush 20, and the output end of the second rotating motor 23 is connected to the end of the roller brush 20. For a logistics box with dust attached to the top, the roller brush 20 is rotated to the downward use position by rotating the movable rod 7, and the roller brush 20 is driven to rotate by the second rotating motor 23. Then, the roller brush 20 abuts against the top of the logistics box and the movable rod 7 moves on the lifting rod 6, so that the dust on the top of the logistics box can be cleaned, which increases the convenience of using the device.

[0043] When the present invention is in use, the device can power the electrical equipment in the device by arranging a battery at the bottom of the mounting plate 1. The device controls the electrical equipment in the device by arranging a control system. The moving wheel used in the device is an electric drive wheel. The first pressure sensor 10 and the second pressure sensor 25 used in the device are both existing mature technologies, so they will not be elaborated on in detail.

[0044] When it is necessary to remove the logistics box on the shelf in the logistics warehouse, the mounting plate 1 is moved to the preset position under the shelf by the moving wheel, and then the connecting rod 5 is driven by the rotating motor 13 to rotate so that the movable rod 7 is rotated to the use position facing the goods side of the shelf, and then the connecting rod 5 is driven upward by the electric telescopic rod 16 to lift and lower. Combined with the lifting electric slider 15 sliding in the lifting slide groove 14, the lifting rod 6 can be driven to rise to the preset use height position. The top and bottom of the movable rod 7 are both provided with rubber pads. The first rotating motor 22 drives the movable rod 7 to rotate so that the two sides of the movable rod 7 with rubber pads on the lifting rod 6 are rotated to the side facing the goods. One side of the flow box, and then through the movement of the mounting plate 1 and the lifting rod 6, the two movable rods 7 are moved to the two sides of the logistics box, and the two movable rods 7 move towards each other to complete the clamping of the logistics box, and then through the lifting and lowering of the connecting rod 5 combined with the rotation of the rotating motor 13, the two movable rods 7 clamp the logistics box and move to the top of the mounting plate 1, and the two movable rods 7 move away from each other so that the logistics box can be placed on the top of the movable plate 2. Through this operation method, the automatic removal and placement of the logistics box on the shelf can be completed, and the position of the logistics box placed on the movable plate 2 can be controlled by controlling the clamping position of the logistics box by the movable rod 7, combined with the movement of the movable rod 7 on the lifting rod 6.

[0045] When the logistics box is placed on the movable plate 2, during the movement of the mounting plate 1, when the mounting plate 1 moves on the ground and vibrates, the vibration will be transmitted to the movable plate 2, causing the movable plate 2 to slide inside the first slot 8, and the first spring telescopic rod 9 will absorb and weaken the sliding force of the movable plate 2. Through this operation method, the shock absorption of the movable plate 2 can be completed, the impact of vibration on the goods on the movable plate 2 can be reduced, and the protection effect of the device on the logistics box can be increased.

[0046] When the logistics boxes are stacked on the movable plate 2, the weight of the logistics boxes presses the movable plate 2 downward, so that the first spring telescopic rod 9 abutting against the first pressure sensor 10 squeezes the first pressure sensor 10, and the first pressure sensor 10 transmits the measured pressure value to the background control system, and the background control system compares the measured pressure value with the standard pressure value. Through this operation method, the weight of the logistics box on the mounting plate 1 can be detected to prevent the weight of the logistics box from exceeding the bearing limit of the mounting plate 1, thereby increasing the safety of the device and extending the service life of the device.

[0047] For a logistics box with dust attached to the top, before clamping and lowering the logistics box, the lifting rod 6 moves to the use position above the top of the logistics box, and then the movable rod 7 is rotated to make the roller brush 20 rotate to the downward use position, and the roller brush 20 is driven to rotate by the second rotating motor 23. Then, the roller brush 20 abuts against the top of the logistics box and the movable rod 7 moves on the lifting rod 6, so as to complete the cleaning of the dust on the top of the logistics box, thereby increasing the convenience of using the device.

[0048] For logistics boxes with load-bearing requirements, before clamping and lowering the logistics box, the abutment block 21 is rotated to the use position facing one side of the logistics box through the rotation of the movable rod 7, and then the two movable rods 7 move closer to each other, so that the abutment block 21 squeezes the outside of the logistics box. The abutment block 21 squeezes the second pressure sensor 25 through the second spring telescopic rod 28, so that the second pressure sensor 25 can transmit the pressure value of the logistics box to the background control system. When the squeezing force reaches the preset value, the state of the logistics box is photographed by the camera on the connecting rod 5 and transmitted to the background control system for graphic comparison, so that the changes of the logistics box under the standard pressure can be detected, thereby completing the detection of the anti-squeezing force of the logistics box itself.

[0049] After the loading of the logistics box on the mounting plate 1 is completed, the movable rod 7 moves to the position as shown in FIG. Figure 1 In the usage state shown, the movable rod 7 then rises to the height usage position of the topmost logistics box on the mounting plate 1. By moving the movable rods 7 closer to each other, the movable rods 7 can enclose the logistics box on the mounting plate 1, thereby fixing the logistics box and increasing the placement stability of the logistics box during transportation.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
