Description

Technical Field

[0001] The utility model relates to the technical field of RFID tags, in particular to an RFID ultra-high frequency cable tie tag with an anti-disassembly function. Background Art

[0002] Radio Frequency Identification (RFID) technology is a non-contact automatic identification technology. It automatically identifies target objects through spatial coupling (alternating magnetic field or electromagnetic field) and obtains relevant data to achieve the purpose of target identification and data exchange, and the identification work does not require manual intervention.

[0003] The basic working principle of RFID technology is not complicated: after the tag enters the magnetic field, it receives the radio frequency signal sent by the RFID reader-writer, and sends out the product information stored in the chip (Passive Tag, passive tag or passive label) by virtue of the energy obtained from the induced current, or actively sends a signal of a certain frequency (Active Tag, active tag or active label); after the reader-writer reads and decodes the information, it is sent to the central information system for relevant data processing.

[0004] With the continuous development of RFID technology, RFID products are gradually applied to all walks of life. At the same time, the application requirements for tags in specific situations are getting higher and higher, and the requirements for the size, appearance and functions of tags are also becoming more and more specialized and irregular. Specialization means that some high-specification items need to use corresponding specification RFID tags for tracking and anti-disassembly management; irregularity means that some items with irregular shapes need to be used with RFID tags to realize the tracking management of items.

[0005] The existing ultra-high frequency tag consists of a substrate, a front metal antenna, a conductive adhesive and a chip. The front metal antenna is attached above the substrate, and the conductive adhesive is located above the metal antenna to connect the metal antenna and the chip. As Figure 3 shown, the conventional RFID ultra-high frequency tag adopts a single loop area + radiation area structure, and mainly optimizes the matching between the chip and the antenna by adjusting the size of the loop area.

[0006] However, the conventional RFID tags cannot meet the application requirements of bending and cable tie bundling, and at the same time cannot meet the anti-disassembly function, and cannot meet the current specific industry requirements. Content of the Utility Model

[0007] The utility model aims at the above problems and provides an RFID ultra-high frequency cable tie tag with a simple structure, convenience and reliability and an anti-disassembly function.

[0008] The technical solution of the present utility model is: an RFID ultra-high frequency cable tie tag with an anti-disassembly function, which includes a substrate, a metal antenna, conductive glue, and a chip. The metal antenna is attached above the substrate, and the chip is connected above the metal antenna through the conductive glue;

[0009] The metal antenna includes a loop area and a pair of radiation areas;

[0010] The loop area is annular, and an opening is provided on the loop area for connecting the chip;

[0011] A pair of radiation areas are symmetrically arranged at one end of the loop area far away from the opening;

[0012] The gap formed between the pair of radiation areas and the opening on the loop area are located at both ends of the metal antenna.

[0013] Glue is provided at the bottom of the substrate.

[0014] Scoring cuts are provided inside the loop area.

[0015] The loop area is in a regular annular shape or an irregular annular shape;

[0016] Among them, the regular annular shape is a circle, an ellipse, or a rectangle;

[0021] In the operation of the present utility model, a structural design with the loop area and both sides of the radiation area is adopted. One side is the loop area, and the other side is the radiation area, which is an asymmetric structure; the chip is placed outside. The anti-disassembly function of the tag can be realized. If the chip or the loop area is damaged, the tag will fail, and if the tag cannot be detected, records and feedback will be made. When the tag is used as a cable tie, it is adhesively fixed to the item through the glue on the back of the tag.

[0022] The present utility model is convenient for processing and has reliable operation. Description of the Drawings
