[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please see Figure 1-5 This utility model provides a technical solution: An RFID-based item identification device includes a support base plate 1, a fixing plate 2 fixedly connected to the upper left part of the support base plate 1, support rods 3 fixedly connected to the upper front and upper rear parts of the fixing plate 2, a support assembly 4 sleeved on the outer surface of the two support rods 3, a fixing frame 5 fixedly connected to the upper middle part of the support base plate 1, a conveyor belt 6 provided on the inner wall of the fixing frame 5, and a support frame 7 fixedly connected to the upper rear part of the fixing frame 5. In this embodiment, the support assembly 4 includes a support plate 41. A storage tank 42 is inserted and connected to the front of the upper end of the support plate 41. A connecting cover 43 is inserted and connected to the upper end of the storage tank 42. A conveying pipe 44 is fixedly connected to the lower right side of the outer surface of the storage tank 42. A connecting plate 45 is inserted and fixedly connected to the lower right side of the support plate 41. A painting device 46 is fixedly connected to the front of the lower end of the connecting plate 45. Two spray nozzles 50 are fixedly connected to the lower end of the painting device 46. A controller 47 is fixedly connected to the rear of the lower end of the connecting plate 45. A camera 48 and an encoding identifier 49 are fixedly connected to the lower end of the controller 47, and the encoding identifier 49 is located in front of the camera 48. The support plate 41 is sleeved with both support rods 3. The connecting plate 45 is inserted and connected to the fixing groove 414. The conveying pipe 44 is fixedly connected to the painting device 46. The above scheme involves connecting the storage tank 42 and the painting equipment 46 through the conveying pipe 44 to supply materials to the painting equipment 46, identifying the RFID code of the items through the code reader 49, recording the video through the camera 48, and spraying the outer packaging of the unqualified items through the painting equipment 46 and two spray heads 50 to facilitate subsequent search and screening.

[0019] In this embodiment, the support plate 41 includes a plate body 411. Two connecting rods 413 are fixedly connected to the lower left part of the plate body 411. A slot 412 is opened at the upper front part of the plate body 411, and a fixing slot 414 is opened at the lower right part of the plate body 411. The plate body 411 is fixedly connected to the connecting plate 45. The two connecting rods 413 are respectively sleeved with the two support rods 3, and the slot 412 is sleeved with the storage tank 42.

[0020] The above scheme involves interlocking the storage tank 42 with the slot 412 to position the storage tank 42, and interlocking the connecting plate 45 with the fixing slot 414 to position the connecting plate 45. This facilitates the use of the painting equipment 46 and the controller 47 and improves stability.

[0021] It should be noted that this utility model is an RFID-based item identification device. During use, before activating the device, the storage tank 42 is aligned with the slot 412 and inserted. The axial limiting and radial constraint of the slot 412 ensure stable positioning of the storage tank 42, preventing paint leakage due to tank shaking during feeding. Simultaneously, the connecting plate 45 of the integrated painting equipment 46 and controller 47 is inserted into the fixing slot 414. The rigid fit between the slot and the connecting plate 45 restricts the lateral displacement of the equipment, ensuring the proper functioning of the spray head 50 of the painting equipment 46. Precisely aligned with the conveyor belt 6, the material supply link connects the storage tank 42 to the painting equipment 46 via the conveyor pipe 44. The controller 47 monitors the supply pressure in real time to ensure stable delivery of paint to the spray head 50, providing continuous supply for marking defective products. Items to be identified (such as food packaging and medicine boxes) are placed on the conveyor belt 6 and enter the identification area. First, the code reader 49 automatically reads the RFID tag information on the surface of the item and transmits the encoded data to the controller 47 in real time. The controller 47 then calls its built-in decryption algorithm to parse the tag. The system uses a dynamic key to sign the item and compares it with the cloud database for basic ID, physical feature code (such as item weight, texture), and logistics trajectory data to complete multi-dimensional identification. Simultaneously, camera 48 is activated to record the item's appearance and RFID tag position, generating a timestamped identification image file (stored in the cloud for subsequent traceability), ensuring that the identification process is traceable and verifiable. If the controller 47 determines that the item is "unqualified" (e.g., tag cloning, physical feature mismatch, abnormal trajectory), it immediately sends a marking instruction to the spray painting equipment 46. After receiving the instruction, the spray painting equipment 46 drives two spray heads 50 to simultaneously spray a specific color marking paint (e.g., red, with abrasion resistance and high recognizability) onto the designated area of ​​the item's outer packaging (e.g., corners, next to the tag, avoiding key information areas), forming a clear unqualified mark to ensure that subsequent manual or automated equipment can quickly identify it. After marking, unqualified items continue to be transported to the designated sorting area by conveyor belt 6, where workers or sorting robots can efficiently screen them by recognizing the marking paint; while qualified items pass without marking and enter the next stage (e.g., warehousing, sales).

[0022] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
