Description

Technical Field

[0001] This utility model belongs to the field of RFID identification technology, specifically relating to an RFID identification device for outbound loading. Background Technology

[0002] In modern logistics warehousing, with the continuous increase in the quantity and variety of goods, traditional manual verification methods for outbound loading are inefficient and prone to errors. Outbound loading RFID identification devices have emerged to address this need. Utilizing radio frequency identification technology, they automatically identify cargo tag information via radio waves, quickly and accurately determining the cargo's identity, quantity, and location. This significantly improves outbound loading efficiency, reduces labor costs, enhances data accuracy, enables automated logistics management and real-time cargo tracking, and strengthens overall logistics operational efficiency and competitiveness.

[0003] Without a stable structure, existing identification devices suffer from RFID tag position changes or unstable distances between the tag and the reader antenna due to shaking during cargo transport, affecting identification performance. A stabilizing structure is needed to maintain a stable posture and position of the cargo during RFID identification, allowing the multiple high-frequency RFID antennas inside the reader to more accurately read the RFID tag information on the cargo. Utility Model Content

[0004] The purpose of this utility model is to provide an RFID identification device for outbound loading, so as to solve the problem that when the existing identification device in the background technology does not have a stable structure, the shaking of the RFID tag during the transportation of goods by the trolley will cause the RFID tag position to change, or the distance between the tag and the reader antenna to be unstable, which affects the identification effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an RFID identification device for loading and unloading, comprising two height adjustment frames and a limiting frame disposed at the upper middle position of the two height adjustment frames;

[0006] A reader is provided at the front of the two height adjustment frames, and an access control machine is provided at the rear of the two height adjustment frames. A length adjustment rod is provided at the lower connection position of the height adjustment frame, the reader and the access control machine.

[0007] The identifier and the access control machine are powered by an external power source.

[0008] The identifier is provided with sleeves at the top and bottom ends and the front and back sides respectively. A sleeve rod is provided inside one side of the sleeve. A tension spring ring is fitted at the middle outer side of the sleeve rod. A limit ring is provided at the connection between the end of the tension spring ring and the sleeve rod.

[0009] A tensioning roller is provided at the middle position of the sleeve rod, which is symmetrically arranged both vertically and horizontally.

[0010] A rotating shaft is provided at the connection position of the upper and lower sleeve rods of the tensioning roller.

[0011] Preferably, the tensioning roller is made of rubber material, and the tensioning roller can rotate within the upper and lower sleeves via a rotating shaft.

[0012] Preferably, the limiting ring is connected to the sleeve by welding, and the two ends of the tension spring coil are connected to the end of the sleeve and the limiting ring by welding, respectively.

[0013] Preferably, the sleeve is connected to the sleeve via a nested connection, and the sleeve can move inside the sleeve.

[0014] Preferably, a connecting plate is provided at the connection position between the sleeve and the identifier, and the connecting plate is connected to the inside of the identifier by external connecting bolts.

[0015] Preferably, multiple RFID high-frequency antennas are respectively provided on the inner side of the identifier and the access control machine, and an RFID IoT controller is integrated on the inner middle side of the limiting frame.

[0016] Preferably, a metal shielding mesh is provided on the outer side of each of the two height adjustment frames, and a fixing frame is provided on the lower front and rear sides of the metal shielding mesh.

[0017] 1. The tension roller is made of rubber, which has good elasticity and friction. When goods come into contact with the tension roller, the friction of the rubber effectively prevents the goods from sliding on the trolley. For example, for some smooth-surfaced packaging, such as products wrapped in plastic film, the rubber tension roller can provide sufficient friction to keep them stationary during transport.

[0018] The elastic structure composed of the sleeve, tube, tension spring coil, and limiting ring can adapt to the shape and pressure of the cargo. If the cargo is irregularly shaped, it will exert pressure on the tension roller in different directions and magnitudes as it passes over the tension roller. At this time, the sleeve moves inside the tube, and the tension spring coil will expand and contract accordingly, ensuring that the tension roller always fits tightly against the cargo. This adaptive characteristic prevents the cargo from rolling or falling due to shaking or bumping, ensuring the integrity and safety of the cargo during transportation.

[0019] 2. Because the goods maintain a stable posture and position, the multiple RFID high-frequency antennas inside the reader can more accurately read the RFID tag information on the goods. Without this stable structure, the movement of the goods may cause the tag position to change, or the distance between the tag and the antenna to become unstable, affecting the recognition effect. For example, when identifying goods containing small electronic components, the RFID tag position is relatively fixed. The stable state of the goods ensures that the distance between the antenna and the tag is within the optimal recognition range, thereby improving the recognition accuracy.

[0020] 3. Stable cargo condition also helps improve recognition efficiency. Because there is no need to make multiple recognition attempts for goods that are shaking or poorly positioned, the recognition time is reduced, allowing the goods to pass through the recognition device more quickly and improving the efficiency of the entire outbound loading process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The utility model provides Figure 1-6 The RFID identification device for loading out of warehouse shown includes two height adjustment frames 5 and a limiting frame 1 set at the upper middle position of the two height adjustment frames 5;

[0030] A reader 3 is installed at the front of the two height adjustment frames 5, and an access control machine 4 is installed at the rear of the two height adjustment frames 5. A length adjustment rod 6 is installed at the lower connection position of the height adjustment frame 5, the reader 3 and the access control machine 4.

[0031] The reader 3 and the access control machine 4 are powered by connecting to an external power source.

[0032] The identifier 3 is provided with sleeves 13 at the top and bottom ends and front and back sides respectively. A sleeve rod 11 is provided inside one side of the sleeve 13. A tension spring ring 12 is fitted in the middle outer side of the sleeve rod 11. A limit ring 10 is provided at the connection between the end of the tension spring ring 12 and the sleeve rod 11.

[0033] A tensioning roller 7 is installed at the middle position of the sleeve rod 11, which is symmetrically arranged at the top and bottom.

[0034] A rotating shaft 9 is provided at the connection position of the upper and lower sleeve rods 11 on both sides of the tension roller 7.

[0035] Multiple RFID high-frequency antennas are installed on the inner side of the reader 3 and the access control machine 4, and an RFID IoT controller is integrated in the middle inner side of the limit frame 1.

[0036] Metal shielding mesh 2 is installed on the outer side of the two height adjustment frames 5, and fixing frames 8 are installed on the lower front and rear sides of the metal shielding mesh 2.

[0037] In this embodiment, the reader 3 and the access control machine 4 obtain power by connecting to an external power source, thereby starting up and entering the working preparation state. The RFID high-frequency antenna in the device is located at the corresponding positions inside the reader 3 and the access control machine 4, while the RFID IoT controller is integrated in the middle inner position of the limit frame 1. They work together to prepare for the identification and processing of RFID tag information of relevant items after power-on.

[0038] When an item with an RFID tag enters between two height adjustment racks 5 and is ready to be loaded onto a vehicle for shipment, the reader 3 located at the front of the height adjustment rack 5 will first identify and detect the RFID tag on the item. During the identification process, multiple RFID high-frequency antennas installed on its inner side will transmit and receive signals to obtain relevant identification information and other data of the item, and transmit this data to the RFID IoT controller located on the inner side of the middle of the limit rack 1 for processing and analysis.

[0039] At the same time, the access control machine 4 located behind the height adjustment frame 5 can also perform operations such as re-inspection and confirmation of items through its own internal RFID high-frequency antenna, further ensuring the accuracy of identification and control over the outbound loading process.

[0040] The metal shielding mesh 2 installed on the outside of the two height adjustment frames 5 can shield external interference signals and ensure that the identification device itself is not affected by external electromagnetic interference. The metal shielding mesh 2 is kept stable by the fixing frame 8 at the lower position of the front and rear sides, so that it can better perform its protective function.

[0041] like Figure 1-6 As shown, the tension roller 7 is made of rubber material and can rotate within the upper and lower sleeve rods 11 via a rotating shaft. The limiting ring 10 is connected to the sleeve rod 11 by welding. The tension spring ring 12 is connected to the end of the sleeve 13 and the limiting ring 10 by welding at both ends. The sleeve rod 11 is connected to the sleeve 13 by nesting connection and can move inside the sleeve 13. A connecting plate 14 is provided at the connection position between the sleeve 13 and the identifier 3. The connecting plate 14 is connected to the inside of the identifier 3 by external connecting bolts.

[0042] Preferably, the tension roller 7 begins to function when the trolley loaded with goods is pushed between the two height adjustment frames 5 and located below the limit frame 1. Because the tension roller 7 is made of rubber, it possesses a certain degree of flexibility and friction.

[0043] First, in the initial state, the sleeve 11 is in a certain position inside the sleeve 13, and the tension spring coil 12 is in a natural or pre-compressed state, applying a certain force to the sleeve 11. When the goods come into contact with the tension roller 7, due to the squeezing or pushing of the goods, the tension roller 7 will rotate between the upper and lower sleeves 11 via the rotating shaft 9 to adapt to the direction and speed of the goods' movement, reducing hard friction and collision with the goods.

[0044] Simultaneously, as the cargo presses against the tension roller 7, the sleeve rod 11 moves within the sleeve 13, further compressing or stretching the tension spring coil 12, adjusting the tension force according to the specific conditions of the cargo. The limiting ring 10 is welded to the sleeve rod 11, limiting the range of movement of the sleeve rod 11, preventing it from excessively displacing and detaching from the sleeve 13, and ensuring the stability of the entire structure.

[0045] The coordinated action of the tension roller 7, sleeve 11, sleeve 13, tension spring coil 12, and limiting ring 10 ensures that the roller maintains close contact with goods of different shapes, sizes, and motion states, providing appropriate support and restraint. On one hand, this effectively prevents goods from rolling or falling due to shaking or bumping during transport, ensuring the integrity and safety of the goods. On the other hand, it allows the goods to maintain a relatively stable posture and position when passing the identifier 3, enabling the multiple RFID high-frequency antennas inside the identifier 3 to more accurately read the RFID tag information on the goods, thereby improving the accuracy and efficiency of identification and facilitating the smooth completion of the outbound loading process and better transportation of the goods.

[0046] The sleeve 13 is securely connected to the identifier 3 via the connecting plate 14 and external connecting bolts, ensuring a tight fit between the entire innovative structure and the identifier 3. This allows the tension roller 7 to function at the appropriate position and angle, and even under repeated impacts and vibrations from goods during long-term use, it can maintain the reliability and stability of the structure, ensuring the continuous and effective operation of the entire identification device.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
