Embodiment 1

[0038] Such as Figure 1 to Figure 3 As shown, the locally fragile electronic tag with controllable position includes a carrier 1, an antenna coil 2 is arranged on the front of the carrier 1, the outermost turn of the antenna coil 2 is disconnected, and the outermost turn of the antenna coil 2 is disconnected. Antenna pin seat 5, the side of antenna pin seat 5 away from antenna coil 2 is provided with anti-detection coil pin seat 6, and a chip 7 is connected between antenna pin seat 5 and anti-detection coil pin seat 6 ;

[0039] An antenna bridge 3 is arranged on the back of the carrier 1, and the antenna bridge 3 communicates with the antenna coil 2 to form a closed-loop coil;

[0040] An anti-detection coil 8 is also arranged on the back of the carrier 1 , the anti-detection coil 8 passes through the carrier 1 and is connected to the pin seat 6 of the anti-detection coil, and a fragile layer 9 is arranged between the anti-detection coil 8 and the carrier 1 .

[0041] The ...

Embodiment 2

[0046] Such as Figure 1 to Figure 3 As shown, the electronic tag production method with controllable local fragile position includes the following steps:

[0047] S1: Making a fragile layer, using the carrier 1 as a base material, coating a fragile layer 9 of equal width and equidistant distance on the back of the carrier 1; the carrier 1 is a PET film.

[0048] S2: Coating composite glue 11 on the front and back sides of the carrier 1 coated with the fragile layer 9 and then compounding the metal foil to obtain the antenna material;

[0049] S3: Antenna coil 2 and anti-detection coil 8 are produced by chemical etching, antenna coil 2 is located on the front of carrier 1 away from the end of fragile layer 9, and anti-detection coil 8 is located on the back of carrier 1 where fragile layer 9 is provided . Usually chemical etching is used to produce antenna coils, and the protective ink is first printed on the surface of the metal foil. During the chemical etching process, th...

Embodiment 3

[0057] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, fragile area coating: choose PET film with a thickness of 38 μm as the base material, use a 300-mesh printing anilox roller with equal intervals, print or coat the fragile layer material on the back of the PET film to make the back Fragile layer 9, the material of this fragile layer 9 is usually made of C9 or C5 resin, acrylic synthetic resin, tackifier, organic solvent and other materials (ratio: 1.8:4:0.3:31), coating Finally, the production of the antenna material is completed through drying in the drying tunnel.

[0058] Fragile area positioning: The fragile layer material described in the present invention is colorless and transparent, and it is usually difficult to distinguish the fragile area after printing and coating on the PET film. In the present invention, an appropriate amount of organic pigment is added during the compounding process of the above-mentioned fragile layer 9 material, and is ...

Abstract

The invention relates to the technical field of electronic tags, in particular to an electronic tag with a controllable local fragile position and a production method. The electronic tag with the controllable local fragile position comprises a carrier, an antenna coil is arranged on the front face of the carrier, the outermost turn of the antenna coil is disconnected, an antenna pin base is arranged at the disconnected position of the outermost turn of the antenna coil; an anti-detection coil pin base is arranged on the side, away from the antenna coil, of the antenna pin base; and a chip is connected between the antenna pin base and the anti-detection coil pin base; an antenna gap bridge is arranged on the back surface of the carrier and is communicated with the antenna coil to form a closed-loop coil; an anti-detection coil is further arranged on the back face of the carrier, the anti-detection coil penetrates through the carrier to be connected with an anti-detection coil pin base,a fragile layer is arranged between the anti-detection coil and the carrier, and the electronic tag which is locally fragile, controllable in position and capable of being used continuously accordingto tag information and the production method are provided.

Description

technical field [0001] The invention relates to the technical field of electronic labels, in particular to an electronic label with a controllable local fragile position and a production method. Background technique [0002] The English full name of RFID is Radio Frequency Identification. RFID radio frequency identification is simply a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The entire identification work does not require manual intervention and can work in various a hostile environment. RFID technology can identify high-speed moving objects and single very specific objects, and can identify multiple tags at the same time. Because it uses radio frequency, it can read data through external materials, and can identify multiple objects at the same time, so it is more convenient and quicker. In addition to these, the biggest feature is that the amount of stored info...
