[0002] RFID tags enable contactless data exchange through electromagnetic waves. A reader transmits a radio frequency signal of a specific frequency. The tag's built-in antenna receives the energy, activating the chip or using its own power source. The tag then transmits the stored data back to the reader through backscatter technology. The entire process takes just milliseconds and supports batch reading and simultaneous identification of multiple tags.

[0003] With the widespread application of RFID technology in logistics, industry and other fields, the fixed structure of the tag needs to meet the requirements of reliability, anti-interference and anti-counterfeiting in complex environments. However, the existing technology has the following core problems:

[0004] Severe electromagnetic interference: Traditional tags experience significant signal attenuation on metal surfaces or in strong electromagnetic environments, resulting in a reading distance of less than 0.3m, affecting warehouse management efficiency.

[0005] Poor fixing stability: Relying on a single adhesive or rigid buckle, it is easy for the adhesive strip to age and the label to fall off due to vibration or changes in temperature and humidity, with a leakage rate as high as 5%. Summary of the Invention

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] like Figure 1-Figure 7 As shown, the RFID tag fixing structure of the present invention includes a fixing base 200 for fixing the connection with the device and supporting the tag;

[0037] The fixing base 200 is made of plastic. A ferrite composite material layer 210 for wave absorption is provided on one side of the fixing base 200. The shielding effectiveness of the antenna area reaches 30dB.

[0038] The plug socket 230 is connected to one side of the fixing base 200 and is arranged in an array along the edge of the fixing base 200;

[0039] Buffer strip 201; A buffer strip 201 is provided on one side of the fixing base 200, and the buffer strip 201 is placed on the inner side of the fixing base 200; the thickness of the ferrite composite material layer 210 is 1mm.

[0040] The ferrite composite material layer 210 is combined with the plastic fixing seat 200 to suppress the eddy current effect on the metal surface while being lightweight. The ferrite composite material layer 210 is 1mm thick, with a frequency response of 0.5-5GHz, an antenna area shielding effectiveness of 30dB, and a metal surface reading distance increased to 1.5m. Next to the motor equipment (electromagnetic field strength 50V / m), the tag reading success rate is 98%, while the success rate of traditional unshielded tags is only 60%. The absorbing layer weighs only 2g, which is more suitable for portable devices. The material can withstand temperatures of -40℃ to 150℃ and is suitable for high-temperature disinfection scenarios.

[0041] The buffer strip 201 is placed between the fixing seat 200 and the label panel 100 to prevent foreign matter from entering between the fixing seat 200 and the label panel 100, making the connection in a sealed state. The buffer strip 201 is made of flexible material and can deform and provide buffering when the label panel 100 is pressed.

[0042] As a technical optimization solution of the present invention, the buffer rubber strip 201 is made of elastic material, and the outer wall is wrapped with a silicone buffer layer.

[0043] The elastic strip is combined with the silicone coating to provide a vertical buffer pressure of 0.2-0.5MPa, reducing label displacement caused by vibration (<0.05mm).

[0044] The buffer strip 201 can play a sealing role, so that the fixing base 200 and the label panel 100 are sealed. The elastic buffer strip 201 can always be in contact with the label panel 100 to prevent foreign matter from entering between the fixing base 200 and the label panel 100.

[0045] As a technical optimization solution of the present invention, the plug socket 230 is provided with a receiving groove 231 at one end away from the fixing base 200, and the receiving groove 231 is provided with multiple groups of through holes;

[0046] A glue bag 204 for storing glue is provided in the storage groove 231 ; a pressing piece 205 for squeezing out the glue and a glue outlet 206 for the glue to flow out are provided on the top of the glue bag 204 .

[0047] When the pressing sheet 205 squeezes the glue capsule 204 , the liquid glue inside is squeezed out through the glue outlet 206 and adheres to the label panel 100 .

[0048] The multiple sets of through-hole receiving grooves 231 allow glue to overflow evenly. Combined with the pressing piece 205 and the glue outlet 206, the glue coverage area can reach 95% in a single press, thereby improving installation efficiency.

[0049] As a technical optimization solution of the present invention, the glue contains epoxy resin glue with stainless steel particles with a diameter of 10 μm, and the peeling strength after curing is greater than 5N / mm.

[0050] The glue is bonded with epoxy resin glue containing stainless steel particles with a diameter of 10μm, making the connection more secure. The ordinary anti-transfer label has only 1N / mm, and the glue layer can be recycled along with the label as a whole, avoiding the problem of special anti-counterfeiting labels needing to be handled separately.

[0051] The peeling test shows that the glue residue rate after illegal removal is >90%, and the pattern can be recognized within 1 second.

[0052] The RFID tag includes a tag panel 100 , with a first adhesive strip 102 and a second adhesive strip 103 respectively provided on both sides of the tag panel 100 ;

[0053] Grooves 101 are provided on both sides of the label panel 100 , and the width of the grooves 101 is greater than the diameter of the rubber strip.

[0054] The first rubber strip 102 is made of silicone rubber, and the second rubber strip 103 is made of fluororubber.

[0055] Groove 101 is 2mm deep and slightly wider than 1.2 times the diameter of the rubber strip, ensuring a 30% compression deformation. The interference fit between groove 101 and connector 230 creates a physical lock, and the rubber strip is compressed to fill the gap, preventing moisture and dust from entering. Reinforced steel strip 161 increases the cross-sectional moment of inertia to enhance overall rigidity. The silicone rubber is resistant to high and low temperatures, while the fluororubber resists chemical corrosion. This dual-material combination improves sealing. Reinforced steel strip 161 strengthens the label's resistance to bending, preventing damage to the chip due to external deformation. The dual-rubber strip sealing system has a leakage rate of <0.01%, while a traditional single-layer rubber strip has a leakage rate of 5% under the same conditions. The dual-material combination (silicone rubber + fluororubber) balances flexibility and high-temperature resistance, avoiding the elastic failure of a single adhesive due to temperature fluctuations (such as cold chain transportation), extending its expected service life to 8 years.

[0056] As a technical optimization solution of the present invention, a connection shell 160 is fixedly provided on one side of the label panel 100. The connection shells 160 are arranged in an array along the edge of the label panel 100, and a reinforcing steel bar 161 is embedded between two adjacent connection shells 160.

[0057] The steel bar only accounts for 5% of the total weight of the shell, avoiding the weight increase problem of traditional metal shells. The embedded stainless steel bar (thickness 0.5mm, width 5mm) is distributed along the connecting shell 160, and the overall strength of the label panel 100 is increased to 120N / mm 2 (The traditional plastic housing is 40N / mm 2 ).

[0058] A polyurethane sponge layer 107 is fixedly provided on one side of the label panel 100 .

[0059] Polyurethane sponge layer 107 (density 80kg / m 3 , porosity 85%), the thickness is 1.2 times the distance between the label panel 100 and the fixing base 200, the vertical pressure is stable in the range of 0.2-0.5MPa, under the conditions of amplitude ±3mm and frequency 10Hz, the vertical displacement of the label is <0.05mm, the moisture absorption rate of the sponge block can reach 190% of its own weight, and the polyurethane sponge 107 is filled between the label panel 100 and the fixing base 200, which effectively alleviates the signal attenuation problem in a humid environment (the reading success rate is increased to 98% in an environment with 90% humidity).

Those skilled in the art should understand that the present invention is not limited to the above-described embodiments.
