Description

Technical Field

[0001] This utility model relates to the field of electronic tags, and in particular to a flexible RFID electronic tag. Background Technology

[0002] In the field of biomedical research, laboratory mice are important model organisms, and the accurate identification and tracking of individual mice are crucial for the accuracy and reproducibility of experimental data and the standardized management of experimental processes.

[0003] Currently, the main methods for identifying laboratory mice include ear tags, tattoos, and implanted RFID tags. While ear tags are simple to use, RFID ear tags for medium to large animals are generally quite large, with a minimum size of about 4 cm and a weight exceeding 4g. This is too heavy for mice, which average only about 8g. Tattoos require professional handling and close observation for identification, making them less efficient. Furthermore, long-term use may cause them to become illegible due to hair growth or skin abrasion on the mouse's ears.

[0004] While implantable RFID tags can achieve high-precision identification and long-term stable use, they require surgical implantation into mice. This not only causes trauma to the mice, potentially triggering stress responses or infection risks, affecting their physiological state and thus interfering with experimental results, but also increases the complexity and time cost of the operation. This problem is particularly prominent in large-scale experimental mouse populations.

[0005] Therefore, developing an identification tagging technology that is non-invasive, causes little trauma to mice, is stable in identification, and is easy to operate has become an important direction to meet the needs of laboratory mouse management. Utility Model Content

[0006] The purpose of this invention is to provide a flexible RFID electronic tag to solve the problems existing in the prior art.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A flexible RFID electronic tag includes a mounting block. The top of the mounting block has a first mounting hole that extends vertically through it, and the top periphery of the mounting block has a second mounting hole that extends vertically through it. The top of the mounting block has a mounting groove in which an RFID antenna is fixedly mounted.

[0009] By adopting the above technical solution, the volume and weight of the mounting block are reduced through improvements to the mounting block volume. Furthermore, the ear-hook method for mice using the first and second mounting holes avoids the problem of implanted RFID identification tags.

[0010] In a further embodiment, a positioning platform is provided at the bottom of the mounting groove. The positioning platform is integrally formed with the mounting block. The axis of the positioning platform is parallel to the axis of the first mounting hole, and the height of the positioning platform is lower than the depth of the mounting groove.

[0011] By adopting the above technical solution, the one-piece positioning platform enhances the overall structure. Its axis, which is parallel to the first mounting hole, ensures the consistency of the antenna installation direction. The design of the positioning platform being lower than the depth of the mounting slot can provide circumferential protection for the RFID antenna and reduce the impact of external collisions on the antenna.

[0012] In a further embodiment, the RFID antenna includes a microchip and a housing. The microchip is fixedly installed inside the housing. The bottom of the housing has a positioning groove corresponding to the positioning platform. The housing is fixedly installed on the positioning platform in the mounting groove.

[0013] By adopting the above technical solution, the outer shell provides physical protection for the microchip, and the cooperation between the positioning slot and the positioning platform enables the precise positioning of the outer shell in the mounting slot, ensuring the consistency of the antenna installation position and improving assembly efficiency and structural stability.

[0014] In a further embodiment, the mounting block includes a main body layer and a protective film layer, the protective film layer covering the surface of the main body layer, and the first mounting hole, the second mounting hole and the mounting groove all penetrating the protective film layer to the main body layer, the protective film layer being used to protect the main body layer.

[0015] By adopting the above technical solution, the main body layer provides basic structural support for the mounting block, the protective film layer covering the surface can isolate wear and corrosion factors in the external environment, extend the service life of the main body layer, and the through holes and grooves ensure the normal realization of the functions of each structure.

[0016] In a further embodiment, the edge of the mounting block is rounded, the inner wall of the first mounting hole and the inner wall of the second mounting hole are both smooth curved surfaces, and the diameter of the second mounting hole is smaller than that of the first mounting hole.

[0017] By adopting the above technical solution, the rounded corner structure avoids the sharp parts of the mounting block edge, reducing the risk of scratching during use. The smooth curved inner wall of the hole reduces the frictional resistance during installation, and the design of different hole diameters allows the mounting structure to be adapted to fixing parts of different specifications, enhancing installation flexibility.

[0018] In a further embodiment, the outer shell surface is provided with anti-slip texture, and a gap is left between the outer shell and the inner wall of the mounting groove. The gap is filled with sealant, which is a flexible sealing material and has waterproof properties.

[0019] By adopting the above technical solution, the anti-slip texture facilitates the installation and disassembly of the shell, the gap provides buffer space for the deformation of the shell and mounting block, and the flexible sealant can adapt to structural deformation while filling the gap, and also has a waterproof sealing function, effectively protecting the internal antenna from the influence of moisture intrusion.

[0020] In summary, this utility model has the following beneficial effects:

[0021] 1. By making holes in the mouse's ear, the mounting block is fixedly installed in the mouse's ear using a clamp. By changing the first or second mounting hole, the electronic tag can be stably installed in different scenarios. The space between the mounting groove and the outer shell is filled with sealant, and the outer shell is restricted by the positioning platform.

[0022] 2. By designing the difference in diameter between the first and second mounting holes, it is possible to adapt to fixing clamps of different specifications, achieve stable installation in multiple scenarios, and improve the flexibility of use. Attached Figure Description

[0028] Example 1:

[0029] like Figures 1-2As shown, a flexible RFID electronic tag includes a mounting block 1. The top of the mounting block 1 has a first mounting hole 3 that runs vertically through it, and the top periphery of the mounting block 1 has a second mounting hole 4 that runs vertically through it. The top of the mounting block 1 has a mounting groove, in which an RFID antenna 2 is fixedly installed. The bottom of the mounting groove has a positioning platform 5, which is integrally formed with the mounting block 1. The axis of the positioning platform 5 is parallel to the axis of the first mounting hole 3, and the height of the positioning platform 5 is lower than the depth of the mounting groove.

[0030] Mounting block 1 is made of PCB material that is not easily bitten, making it more durable. It can also undergo various sterilization treatments before the experiment, making it less prone to damage.

[0031] The RFID antenna 2 includes a microchip and a housing. The microchip is fixedly installed inside the housing. The bottom of the housing has a positioning groove corresponding to the positioning platform 5. The housing is fixedly installed on the positioning platform 5 in the mounting groove. The mounting block 1 includes a main body layer and a protective film layer. The protective film layer covers the surface of the main body layer. The first mounting hole 3, the second mounting hole 4 and the mounting groove all penetrate the protective film layer to the main body layer. The protective film layer is used to protect the main body layer.

[0032] The outer shell is made of polyimide, combining flexibility and corrosion resistance to protect the chip from biological fluids. The protective film, made of polyethylene terephthalate, covers the surface of the main layer and has uniform thickness with good wear resistance and chemical corrosion resistance, protecting the main layer from mouse secretions and contaminants in the experimental environment.

[0033] Mounting block 1 has rounded edges. The inner walls of the first mounting hole 3 and the second mounting hole 4 are both smooth curved surfaces. The diameter of the second mounting hole 4 is smaller than that of the first mounting hole 3. The outer shell surface has anti-slip textures. A gap is left between the outer shell and the inner wall of the mounting groove, and the gap is filled with sealant. The sealant is a flexible sealing material with waterproof properties. Silicone rubber sealant can be used. The sealant can deform synchronously with the bending of mounting block 1 without cracking. After the sealant completely fills the gap, it forms a sealed protective layer, which can prevent moisture and dust from entering the interior of RFID antenna 2, and also buffer the vibration generated by mouse movement, avoiding damage to the microchip due to frequent impacts.

[0034] Specific implementation process: Avoiding blood vessels, a tiny hole is drilled in the middle of the mouse's auricle using a sterile ophthalmic drill, matching either the first mounting hole 3 or the second mounting hole 4. The two claws of the clamp are then inserted through the hole in the mouse's auricle and into the first mounting hole 3 or the second mounting hole 4 of the mounting block 1, respectively. If the tag's fixed position needs to be changed to adapt to different monitoring scenarios, simply remove the clamp claws from the current mounting hole and re-insert them into another mounting hole. After the mounting block 1 is fixed, check the alignment of the mounting groove and the RFID antenna 2 housing to ensure that the positioning groove at the bottom of the housing precisely engages with the positioning platform 5 within the mounting groove. Then, using a sterile syringe, sealant is evenly injected into the gap between the housing and the inner wall of the mounting groove, filling the gap without overflowing. After the sealant cures, it forms a sealed protective layer, preventing the intrusion of external dust and moisture. The engagement structure of the positioning platform 5 and the positioning groove effectively restricts the lateral and longitudinal displacement of the housing during mouse movement, ensuring that the RFID antenna 2 always maintains a stable signal transmission and reception posture.
