Description

Technical Field

[0001] This utility model relates to the field of radio frequency identification technology, specifically to a silicone rubber ultra-high frequency smart tag. Background Technology

[0002] Silicone rubber UHF smart tags are a new type of smart tag based on UHF RFID technology, using silicone rubber as the core encapsulation material. As the Internet of Things (IoT) penetrates into complex scenarios such as Industry 4.0, smart healthcare, and outdoor facility management, the environmental adaptability requirements for these tags are significantly increasing.

[0003] However, ordinary UHF tags mostly use rigid substrates such as PET and PCB, which are difficult to adhere to curved or flexible objects such as tires and cables, and have poor impact resistance and are easy to break. These needs have driven the combination of "silicone rubber + UHF RFID" technology, giving rise to the research and development of silicone rubber UHF smart tags. Utility Model Content

[0004] The purpose of this invention is to provide a silicone rubber ultra-high frequency smart tag to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a silicone rubber ultra-high frequency smart tag, comprising a top sealing layer and a base layer, wherein the top sealing layer is located above the base layer;

[0006] The antenna layer, embedded inside the top sealing layer, is made of conductive silver paste and has an axisymmetric geometric layout.

[0007] The chip is fixed in the central region of the substrate and electrically connected to the antenna layer;

[0008] The protective flange is integrally formed around the edge of the top cap and base layer, and has a semi-circular cross-section.

[0009] Preferably, the substrate layer has an adhesive layer on the side away from the antenna layer, and the adhesive layer thickness is 0.05-0.15mm.

[0010] Preferably, a fixing block is embedded in the top of the base layer, and the chip is movably inserted into the inner side of the fixing block.

[0011] Preferably, ceramic microspheres are uniformly distributed inside the top sealing layer and the base layer.

[0012] Preferably, the surface of the conductive path of the antenna layer is covered with an insulating layer.

[0013] Preferably, the inner side of the protective flange is provided with a reinforcing rib, and the extension direction of the reinforcing rib forms an angle of 15-45° with the long side of the label.

[0014] Preferably, the surface of the top seal layer is provided with an anti-slip texture, which is distributed in an interlaced grid pattern.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes silicone rubber with a Shore hardness of 40-60A, which combines flexibility and durability, allowing it to bend and fit complex surfaces. The label maintains stable electrical performance of the antenna layer even when repeatedly bent (such as in dynamic surface labeling). Furthermore, the protective flange and the base layer are molded synchronously, eliminating seam weaknesses. While protecting the edges, it also prevents delamination or tearing. Traditional labels use conductive adhesive or welding to fix the chip, which is prone to failure after long-term use due to adhesive aging or solder fatigue. The fixing block uses a mechanical fixing method to fix the chip, avoiding the weaknesses of adhesive / welding processes. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-4 This utility model provides a technical solution: a silicone rubber ultra-high frequency smart tag, including a top sealing layer 1 and a base layer 5, wherein the top sealing layer 1 is located above the base layer 5;

[0024] Antenna layer 4, embedded inside top sealing layer 1, is made of conductive silver paste and has an axisymmetric geometric layout;

[0025] Chip 10 is fixed in the central region of substrate 5 and electrically connected to antenna layer 4;

[0026] The protective flange 2 is integrally formed around the edge of the top sealing layer 1 and the base layer 5, and has a semi-circular cross-section.

[0027] Furthermore, an adhesive layer 6 is provided on the side of the substrate layer 5 away from the antenna layer 4. The adhesive layer is a pressure-sensitive layer with a thickness of 0.05-0.15 mm to ensure initial adhesion while allowing for peeling without residual adhesive.

[0028] Furthermore, a fixing block 9 is embedded in the top of the base layer 5, and the chip 10 is movably inserted into the inner side of the fixing block 9. This mechanical fixing method can not only avoid damage to the silicone rubber from high-temperature welding, but also avoid the problem of adhesive aging.

[0029] Furthermore, ceramic microspheres 8 are uniformly distributed inside the top sealing layer 1 and the base layer 5, which improves the thermal conductivity of the silicone rubber, prevents the chip from overheating, and maintains the flexibility of the base while improving its puncture resistance.

[0030] Furthermore, the surface of the conductive path of the antenna layer 4 is covered with an insulating layer 3 to prevent electrochemical corrosion in humid environments.

[0031] Furthermore, the inner side of the protective flange 2 is provided with a reinforcing rib 7, the extension direction of the reinforcing rib 7 forming an angle of 15-45° with the long side of the label, dispersing the edge stress to the base layer and preventing the flange from breaking.

[0032] Furthermore, the surface of the top sealing layer 1 is provided with an anti-slip texture, which is distributed in an interlaced grid pattern to increase the friction coefficient between the label and the mounting surface. The interlaced grid pattern disperses the surface force to multiple nodes, reducing local tensile stress.

[0033] Working principle: The top sealing layer 1 and the base layer 5 are both made of flexible silicone rubber material with a thickness of 0.5-2mm and a Shore hardness of 40-60A. Installation sequence: First, insert the chip 10 into the fixing block 9 for fixing. Mechanical fixing of the chip 10 can not only avoid damage to the silicone rubber by high-temperature welding, but also avoid the problem of adhesive aging. Then, attach the insulating layer 3 to the surface of the antenna layer 4. The top sealing layer 1, which is embedded with the antenna layer 4 and the insulating layer 3, and the chip 10 are electrically connected to each other. At this time, the contacts of the antenna layer 4 are exposed. When the top sealing layer 1 and the antenna layer 4 are installed, the inner wall of the notch in the middle section can block the chip 10. The contacts of the antenna layer 4 can fix the top of the chip 10, thereby further improving the fixing effect of the chip 10. Then, the protective flange 2 is installed on the whole package, and finally, it is molded.
