In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0028] An intelligent cargo box sorting and transfer mechanism based on RFID positioning, such as Figures 1-8As shown, the system includes a warehouse body 1, a lifting platform 2 for receiving and delivering goods, a storage rack 3 driven by pulleys, and a goods retrieval and delivery mechanism. The warehouse body 1 has a top opening 11, a middle opening 12, and a bottom opening 13. The top opening 11 is configured for the docking height of the drone, the middle opening 12 is configured for a manual retrieval layer, and the bottom opening 13 is configured for a robot operation layer. The warehouse body 1 also includes: four external square-framed flaps with inner circular holes, a vertical lifting rod 22 for driving the lifting platform 2, a square outer frame 35 with rounded corners in the middle, and two rows of rollers 21 located inside that roll back and forth via gear transmission. The frames of the top opening 11, middle opening 12, and bottom opening 13 are fixed to the frame of the warehouse body 1 through an embedded structure. Each opening edge is equipped with a 0.5cm thick sealing strip to ensure airtightness during drone docking. The inner circular holes of the square-framed flaps 23 are interference-fitted with the vertical lifting rod 22, and are reinforced with epoxy resin after verticality calibration. The gear at the shaft end of roller 21 meshes with the output gear of the drive motor. The rotation speed of roller 21 is adjusted by the servo controller to ensure that the sliding acceleration of the goods is ≤0.3m / s² when the lifting platform 2 is tilted at a 15° angle. The pressure sensor monitors the load-bearing status of roller 21 in real time to achieve dynamic balance during transportation.

[0029] The storage rack 3 adopts a four-layer U-shaped structure, and each layer has a fixed interval. The layers and structure are as follows: the first layer 31 is set as the robot receiving and delivery layer; the second layer 32 is set as the first storage layer; the third layer 33 is set as the manual receiving and delivery layer; the fourth layer 34 is set as the second storage layer; each layer includes an outer frame 35 and an inner frame 36 with concentric sides, and the outer frame 35 and the inner frame 36 are connected by an arc angle extension 37. Each layer can store a number of boxes.

[0030] The cargo handling mechanism includes: a touch panel 4 located on the side of the compartment 1; a 7-shaped push rod 57 connected by a tenon and mortise joint between a long cylindrical column 51 and a short square plate 52, which can rotate inward 90° to push the cargo; a sorting fork 6, including two pairs of right-angle forks with hooks 61 at the ends, which fit into the slots at the bottom of the cargo box and are driven by a double round rod frame 62; three rows of plates 7, including two side plates 71 and a middle plate 72; and two rotating parallel rods 8, including a stabilizing rod 81 and a fixing rod 82, which rotate 90° via gears to abut against the side of the cargo box.

[0031] In the cargo storage process, when the drone delivers the goods, as the drone carrying the cargo box approaches the warehouse 1, the RFID reader (not shown in the figure) built into the top warehouse opening 11 scans the RFID tag on the cargo box at a frequency of 10Hz. Using 5G positioning technology, the drone's coordinates are calculated, guiding it to descend vertically to a position directly above the warehouse opening. The cargo box slides through the warehouse opening into the lifting platform 2, which descends to the target layer. The RFID reader built into the top warehouse opening 11, along with the RFID tag affixed to the cargo box, guides the drone to its designated location for docking. The maximum operating angle of the gear transmission of the lifting platform 2 forms a 15° angle with the vertical plane.

[0032] If goods are delivered by robots, they are placed on the robot receiving and delivery layer, and the sorting fork 6 moves the boxes to the inner perimeter of the U-shaped structure for storage. If they are ordinary storage goods, they are placed on the first or fourth storage layer according to the system schedule. The rollers 21 connect with the U-shaped track on the outside of the shelf, and the boxes slide into the designated storage location along the track. The RFID tag updates the box location information to the management system in real time.

[0033] In the scenario of manual / robot delivery, when a person delivers goods through the central warehouse opening 12, the goods are placed on the lifting platform 2. The user inputs the goods information on the touchpad 4, and the system automatically allocates an empty storage space on the first or fourth storage layer. The lifting platform 2 then rises to the corresponding layer to complete the storage. When a robot delivers goods through the bottom warehouse opening 13, it uses visual recognition technology to align with the warehouse opening. The cargo box is directly transported to the first layer 31 via the lifting platform 2 and rollers 21, and then transferred to the upper storage space by the matching sorting mechanism.

[0034] The multi-layer box sorting process, when the target goods are located in the middle layer of multi-layer stacked boxes (e.g., three boxes are stacked on the second layer, and the target is the middle layer), the sorting mechanism performs the following steps: Positioning and pre-adjustment: The system determines the coordinates of the target box through RFID, the lifting platform 2 rises to below the target layer, and is adjusted to a 15° tilt angle to align with the inner rail of the shelf. Upper-layer box separation: The double round rod frame 62 is driven to rise, and the end hook 61 is inserted into the bottom slot of the upper-layer box. After being lifted 0.1 meters, it moves laterally to the temporary storage area on the side of the shelf. The two parallel rotating rods 8 rotate synchronously 90°, and the stabilizing rod 81 abuts against the side of the remaining box to prevent it from tipping over.

[0035] Target cargo box retrieval: The right-angle fork is inserted into the bottom of the target cargo box to separate it from the bottom cargo box. The three-row plate 7 drives the right-angle fork to move horizontally, transferring the target cargo box to the lifting platform 2 roller 21. The fixing rod 82 keeps the bottom cargo box stable.

[0036] Return and Output: The lifting platform 2 descends to the middle compartment 12 or the bottom compartment 13, and the 7-shaped push rod 57 rotates inward 90° to push the cargo box to the compartment opening, completing the sorting.

[0037] The system control logic is implemented using capacitive sensing technology on touchpad 4, which supports barcode / picking code scanning input. After receiving the picking instruction, the system performs the following: 1. Data interaction: Information such as the location, layer, and stacking status of the cargo box is obtained through an RFID reader to generate a 3D cargo location map; 2. Path planning: The priority order is: drone pick-up > robot operation > manual picking; 3. Mechanism linkage: Instructions are sent to the lifting platform 2 drive module (controlling vertical lifting and angle adjustment), the sorting fork 6 servo motor (controlling the displacement and rotation of the right-angle fork), and the rotating parallel two-bar stepper motor 8 (controlling the cargo stabilization action). All execution components are synchronously controlled through the CAN bus, and the position sensor provides real-time feedback on the mechanism status to ensure that the sorting accuracy error is ≤2mm.

[0038] For safety and reliability, each compartment opening of the storage unit 1 is equipped with an adaptive sensing system that detects foreign objects and immediately stops operation; the lifting platform 2 is equipped with an overload protection device that triggers emergency braking when the load on a single roller 21 exceeds 50kg; the gap between the hook 61 and the slot of the cargo box is ≤0.5mm to ensure no slippage when grabbing goods; the surface of the rotating parallel rods 8 is covered with an anti-slip rubber layer, and the contact pressure is ≥10N / cm² when stabilizing the goods, effectively preventing the cargo box from tipping over.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
