Description

Technical Field

[0001] This utility model relates to the field of RFID tag technology, and in particular to an anti-transfer tag. Background Technology

[0002] Anti-transfer tags, also known as anti-counterfeiting tags, are identifiers with anti-counterfeiting functions, allowing for the identification of genuine products. With the rapid development of the Internet of Things and intelligent manufacturing, electronic tags (such as RFID tags), as core components for item identification and data carriers, have been applied in various fields such as logistics warehousing, industrial production, and asset management. One of their main uses is as anti-transfer tags.

[0003] RFID technology primarily uses radio waves for contactless communication and can penetrate various media. However, metal materials reflect most radio waves, so RFID tags cannot be read when directly pasted on a metal surface. This means that existing RFID anti-transfer tags cannot be used in the anti-counterfeiting process of metal components.

[0004] Therefore, there is a need for an anti-transfer label that can be directly affixed to metal surfaces and has an anti-transfer effect. Utility Model Content

[0005] The main purpose of this invention is to provide an anti-transfer tag that solves the problem that existing RFID tags are difficult to prevent from being transferred after being pasted on a metal surface.

[0006] To achieve the above objectives, the present invention proposes an anti-transfer tag comprising:

[0007] The surface material layer has an adhesive surface and a scanning surface, the adhesive surface and the scanning surface are arranged in a stepped manner, and a stepped groove is formed on one side of the scanning surface;

[0008] An antenna layer is bonded to the mating surface along the groove wall of the stepped groove. The antenna layer is also provided with antenna pins, which are disposed on the periphery of the antenna layer. The antenna pins extend outward from the geometric center of the antenna layer. A stepped concave surface is formed on the side of the antenna layer away from the face material layer.

[0009] An elastic layer, comprising an adhesive surface and a supporting surface, wherein the adhesive surface is bonded to the stepped concave surface and the supporting surface is bonded to the surface of the metal equipment.

[0010] Preferably, the number of antenna pins is two, the two antenna pins are symmetrically arranged, and the extension direction of the two antenna pins is from the geometric center of the antenna layer along the length direction of the face material layer to both ends of the face material layer.

[0011] Preferably, the antenna layer is a single-layer planar antenna, the antenna layer has a gap, the width of the gap is 0.1~0.2mm, and the antenna layer is made of aluminum foil.

[0012] Preferably, the bottom surface of the bonding surface and the bottom surface of the antenna pin are located on the same horizontal plane, and the bottom surface of the scanning surface is bonded to the top surface of the antenna pin.

[0013] Preferably, the width of the foam is equal to the width of the antenna layer, the length of the elastic layer is less than the length of the antenna layer, and the material of the elastic layer includes, but is not limited to, foam.

[0014] This invention prepares an anti-transfer tag by forming a face material layer, an antenna layer, and an elastic layer. One side of the anti-transfer tag is coated with adhesive, which is used to attach the anti-transfer tag to the surface of a metal device. After attachment, the anti-transfer tag forms a resonant circuit with the surface of the metal device, and the surface of the metal device serves as a gain antenna to achieve signal transmission. The antenna layer also has antenna pins. When the anti-transfer tag is moved, the antenna pins are damaged, leaving only the antenna body. After the transfer, the antenna body cannot form a resonant circuit with the surface of the metal device and therefore lacks signal transmission capability, thus achieving the technical effect of preventing transfer after being attached to the surface of the metal device.

[0025] like Figures 1-3 As shown, this utility model proposes an anti-transfer label 1000, including: a face material layer 100, the face material layer 100 is provided with an adhesive surface 110 and a scanning surface 120, the adhesive surface 110 and the scanning surface 120 are arranged in a stepped manner, and a stepped groove is formed on one side of the scanning surface 120.

[0026] Antenna layer 200 is bonded to mating surface 110 along the groove wall of stepped groove. Antenna layer 200 is also provided with antenna pins 210. Antenna pins 210 are disposed on the periphery of antenna layer 200. The extension direction of antenna pins 210 is outward from the geometric center of antenna layer 200. A stepped concave surface is formed on the side of antenna layer 200 away from face material layer 100.

[0027] The elastic layer 300 includes an adhesive surface and a support surface. The adhesive surface is bonded to the stepped concave surface, and the support surface is bonded to the surface of the metal equipment 2000.

[0028] Understandably, most of the existing anti-transfer labels 1000 used on metal equipment 2000 are injection molded from materials such as PVC and ABS. These labels need to be fixed with screws or other means during use, making them easy for operators to reuse and reducing their anti-counterfeiting effect.

[0029] In this embodiment, after the anti-transfer tag 1000 is affixed to the surface of the metal device 2000, the antenna layer 200 includes an antenna body and antenna pins 210. The antenna pins 210 are disposed at both ends of the antenna body and extend along the length direction of the surface material layer 100. The antenna pins 210 are in contact with the metal. The antenna body is covered by the elastic layer 300. The antenna body and the surface of the metal device 2000 are separated by the elastic layer 300, that is, the antenna body and the surface of the metal device 2000 form a resonant circuit. Then, the surface of the metal device 2000 is used as a gain antenna to achieve the effect of signal transmission.

[0030] Detailed, such as Figure 1 As shown, in this embodiment, the surface material layer 100 has a U-shaped structure. The side of the scanning surface 120 away from the metal device 2000 to be bonded is the top surface, and the side close to the metal device 2000 to be bonded is the bottom surface. The top surface of the scanning surface 120 is printed with the equipment information of the metal device 2000 for easy identification by the operator. The bottom surface is coated with adhesive for bonding to the surface of the metal device 2000. The bonding surface 110 is arranged circumferentially along the scanning surface 120, and there is a height difference between the bonding surface 110 and the scanning surface 120 to form the scanning surface 120. A stepped groove is formed on the side of the scanning surface 120 close to the metal device 2000. The antenna layer 200 is bonded along the groove wall of the stepped groove, so that the side of the antenna layer 200 close to the metal device 2000 forms a stepped concave surface. One side of the elastic layer 300 is bonded to the stepped concave surface, and the other side is bonded to the surface of the metal device 2000. When the anti-transfer tag 1000 is peeled off, the antenna pin 210 remains attached to the metal device 2000, preventing the anti-transfer tag 1000 from forming a circuit and thus making it impossible to read data. This achieves the anti-transfer effect of being able to be directly pasted onto the metal surface.

[0031] In one embodiment, there are two antenna pins 210, which are symmetrically arranged and extend from the geometric center of the antenna layer 200 along the length of the face material layer 100 to both ends of the face material layer 100.

[0032] In this embodiment, as Figure 2As shown, two antenna pins 210 extend to both ends of the face material layer 100 along its length, and the bottom surfaces of the two antenna pins 210 are bonded to the surface of the metal device 2000. The length distance between the ends of the two antenna pins 210 is greater than the length distance of the elastic layer 300. This ensures that when the anti-transfer antenna is peeled off again after being pasted, only the antenna body is peeled off from the face material layer 100 and the elastic layer 300, while the antenna pins 210 remain attached to the original surface of the metal device 2000. When the anti-transfer antenna is transferred to the surface of another metal device 2000, the lack of antenna pins 210 prevents the formation of a resonant circuit, thus making it impossible to read data. This achieves the technical effect of the anti-transfer tag 1000 that can act on the surface of the metal device 2000.

[0033] In one embodiment, the antenna layer 200 is a single-layer planar antenna, the antenna layer 200 has a gap, the width of the gap is 0.1~0.2mm, and the material of the antenna layer 200 is aluminum foil.

[0034] In this embodiment, as Figure 3 As shown, the antenna layer 200 is a single-layer planar slot antenna, which means that the antenna layer 200 has no folding structure. Compared with the engineering plastic electronic tags in the prior art, this anti-transfer tag 1000 has a better flexibility and can be attached to curved metal surfaces, increasing the applicable scenarios. Compared with traditional flexible anti-metal tags, it reduces material and process costs because there is no folding process.

[0035] In one embodiment, the bottom surface of the bonding surface 110 and the bottom surface of the antenna pin 210 are located on the same horizontal plane, and the bottom surface of the scanning surface 120 is bonded to the top surface of the antenna pin 210.

[0036] In this embodiment, the bottom surface of the bonding surface 110 and the bottom surface of the antenna pin 210 are located on the same horizontal plane, which is the outer surface of the metal device 2000. The antenna body is spaced apart from the metal device 2000 through the elastic layer 300, so that the antenna layer 200 and the metal device 2000 form a resonant circuit, which can read the information recorded in the antenna layer 200 normally. The elastic layer 300 is disposed in the cavity formed between the antenna body and the outer surface of the metal device 2000.

[0037] In one embodiment, the width of the foam is equal to the width of the antenna layer 200, the length of the elastic layer 300 is less than the length of the antenna layer 200, and the material of the elastic layer 300 includes, but is not limited to, foam.

[0038] In this embodiment, the geometric centers of the elastic layer 300 and the face material layer 100 are on the same axis. The face material layer 100 covers the antenna layer 200, and the antenna layer 200 covers the elastic layer 300. The antenna pins 210 of the antenna layer 200 can be directly bonded to the surface of the metal device 2000. The antenna pins 210 and the surface of the metal device 2000 are in contact, and the antenna body is isolated from the surface of the metal device 2000 through the elastic layer 300 to form a resonant circuit. The metal device 2000 is used as a gain antenna to achieve signal transmission. When the anti-transfer tag 1000 is transferred, the antenna pins 210 are disconnected from the antenna body. After the anti-transfer tag 1000 is transferred, it cannot form a resonant circuit, thus achieving the anti-transfer and anti-counterfeiting effects.

[0039] This invention creates an anti-transfer tag by fabricating a face material layer, an antenna layer, and an elastic layer. Adhesive is coated on the side of each layer closest to the metal device, allowing the anti-transfer tag to be adhered to the metal device surface. After adhesion, the anti-transfer tag forms a resonant circuit with the metal device surface, using the metal device surface as a gain antenna to achieve signal transmission. The antenna layer also has antenna pins; when the anti-transfer tag is moved, the antenna pins are damaged, leaving only the antenna body. Once the anti-transfer antenna is moved from its original device, the antenna body can no longer form a resonant circuit with the metal device surface, losing its signal transmission capability. This achieves the technical effect of preventing transfer after being adhered to the metal device surface.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
