Technical Field

The utility model relates to an electronic tags technical field, in particular to RFID electronic tags based on temperature sensing paper.

Background

The application of the RFID (radio frequency identification) technology is more and more extensive, and the RFID technology is widely applied to the fields of clothing, asset management, logistics express delivery, product tracing and the like, and consists of software, an RFID reader-writer and an RFID electronic tag. The RFID electronic tag is also called as a radio frequency tag and a transponder; the RFID electronic tag and the reader realize energy transfer and data exchange through electromagnetic coupling or electromagnetic waves; the basic structure of the RFID electronic tag comprises a tag antenna and electronic chips, wherein each chip has a unique electronic code and can write information required by a user, so that the identification of commodities or goods is realized. In the prior art, the electronic tag still has the following defects: (1) the tag antenna adopts a traditional aluminum etching antenna, an aluminum foil is laminated on a PET or PP film, then the aluminum foil is etched through acid materials through the processes of sensitization, exposure and the like, and areas except the antenna pattern are etched away to leave an antenna area; the production process has the disadvantages of great environmental pollution and relatively high cost; (2) the anti-counterfeiting and anti-theft functions are not provided, and the safety performance is poor; consequently the utility model discloses developed a RFID electronic tags based on temperature sensing paper to solve the problem that exists among the prior art, through the retrieval, not discover with the utility model discloses the same or similar technical scheme.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose is: the RFID electronic tag based on the thermal paper is provided to solve the problems that the electronic tag in the prior art is large in production environment pollution, high in cost and poor in use safety performance.

The technical scheme of the utility model is that: an RFID electronic tag based on thermal paper comprises release paper, a back glue layer, an antenna layer and the thermal paper which are sequentially stacked; the antenna inlay layer comprises a printed antenna and a chip; the printed antenna is printed on one side, close to the back glue layer, of the thermal sensitive paper through a conductive material and is bound with the chip; the thermal paper comprises a printing substrate and a thermal coating.

Preferably, the conductive material is one of conductive ink, conductive silver paste or graphene ink.

Preferably, the printed antenna is of a coil structure, an insulating layer and a bridging layer are arranged at one side end of the printed antenna, the insulating layer is formed by printing insulating ink, and the bridging layer is communicated with the inner ring and the outer ring of the printed antenna.

Preferably, the peel strength of the backsize layer is higher than the adhesion between the printed antenna and the printed substrate.

Compared with the prior art, the utility model has the advantages that:

(1) the printed antenna is made by printing the conductive material, so that the pollution is small and the production process is simple; printing antenna direct printing has effectively reduced manufacturing cost on the temperature-sensitive paper, and the temperature-sensitive paper label printer that is equipped with the use simultaneously is small and exquisite portable, consequently the utility model discloses an implant RFID electronic tags in the temperature-sensitive paper, can be used to the price label of express delivery commodity circulation face list, retail trade etc. help promoting the commercial of RFID technique in commodity circulation, express delivery trade, improve the production efficiency of these trades.

(2) Because the peel strength of gum layer is higher than the adhesive force between printed antenna and the printing substrate, consequently when tearing off RFID electronic tags, inside printed antenna is easy to be destroyed for the structure has breakable anti-fake function, and the security performance is good.
