Description

Frangible anti-metal electronic tag

Technical field

The present invention relates to technical field of RFID, is specifically a kind of frangible anti-metal electronic tag.

Background technology

Electronic tag is also known as radio-frequency (RF) tag, transponder, data carrier; Reader is also called readout device, scanner, read head, communicator, read write line (depend on electronic tag whether can wireless rewrite data).Realize the contactless of radiofrequency signal by coupling element between electronic tag with reader to be coupled, in coupling channel, according to sequential relationship, realize transmission and the exchanges data of energy.People stick this radio-frequency (RF) tag as metal label on metal, and utilize the chip of label to read and write about composition kind, the manufacturer of metal, the information such as channel of selling goods, so that management.

The chip that the metal label of prior art generally comprises substrate, is located at the signal line (i.e. antenna) on substrate and is electrically connected with signal line, described chip and signal line form a loop.There is following defect in the metal label of prior art: chip and the complete signal circuit entirety of this metal label are pasted on pet substrate, metal label can not damaged by whole peeling, like this, metal label still can continue to use and can not have influence on the function of normal receiving and transmitting signal, therefore, minority lawless person utilizes this leak, easily metal label changed or reuse, such as, palm off to prevent metal, the metal label on metal is pasted for the purpose of supervision metal quality, be attached on other or fake and inferior metal after being torn, meeting scramble data, harm product safety, therefore metal label can be taken off easily and recycle the original intention just obviously having run counter to use metal label.

Summary of the invention

The technical problem to be solved in the present invention is, provides a kind of energy protect IC not to be subject to metal and disturbs the frangible anti-metal electronic tag that can effectively prevent from again being recycled by lawless person.

Technical solution of the present invention is, provides a kind of frangible anti-metal electronic tag with following structure, the chip that it comprises substrate, is located at the signal line on substrate and is electrically connected with signal line, and described chip and signal line form a loop,

It also comprises the facial tissue layer, EVA separation layer, aluminium lamination and the ground paper layer that are made up of fragile paper;

The lower surface of facial tissue layer and the upper surface of substrate bond;

Substrate is made up of rupture diaphragm; Signal line and chip are all positioned at the lower surface of substrate, and the lower surface of substrate and the upper surface of EVA separation layer bond;

The lower surface of EVA separation layer and the upper surface of aluminium lamination bond;

The lower surface of aluminium lamination scribbles seccotine, and aluminium lamination lower surface bonds through seccotine and ground paper layer upper surface, and the upper surface of ground paper layer scribbles silicone oil;

EVA separation layer and aluminium lamination are provided with and run through above-mentioned two-layer many groups tool marks, often group comprises two tool marks be located along the same line, non-through but leave the adhesion point of between two tool marks with group, EVA separation layer and aluminium lamination are organized tool marks head and the tail more and are connected the region that a circle is surrounded as and constitute easily separated region; Chip and fraction signal line and easily separated area bonded, and the signal line of remainder and easily separated other area bonded extra-regional.

After adopting above structure, the frangible anti-metal electronic tag of the present invention compared with prior art, has the following advantages:

The use procedure of this label is, first tear ground paper layer, aluminium lamination lower surface is attached on metal, when removing by force, aluminium lamination in easily separated region and substrate bond with the upper and lower surface of EVA separation layer respectively, and EVA separation layer foam is many, gluing effect is good especially, therefore the substrate in easily separated region, EVA separation layer and aluminium lamination three bond firmly as a whole, this entirety is bonded in by metal by the strong rubber of aluminium lamination lower surface, and the External Force Acting that label is subject to is in easily separated extra-regional neighboring area, neighboring area through several adhesion point to the power transmission of easily separated region, this power is obviously less than the cohesive force that easily separated region is subject to, therefore the substrate in last easily separated region, EVA separation layer and aluminium lamination are stayed by metal, and other neighboring area of label is torn by force, the chip of substrate and part signal circuit remain in other signal lines on metal and are torn, complete signal circuit is destroyed, tag defeat.

To sum up, when label is removed by force, complete signal circuit is destroyed, and label cannot be reused, and has stopped minority lawless person and has utilized leak to divert the harm of label.

And, there is the bright spot in several design in frangible anti-metal electronic tag of the present invention: first, in order to anti-metal interference, be provided with the adverse effect that EVA separation layer reduces metal pair tag performance as far as possible, and EVA separation layer foam is many, plybonding effect is good, like this, also can by substrate, EVA separation layer and aluminium lamination bonding firmly with common glue, when ensureing to remove by force, substrate breakage is cracked; But the impact of metal pair tag performance can not thoroughly be got rid of, like this, different by the metal pasted, also different on the impact of the performance parameter of label, cause unitarity and the poor stability of label, therefore under metal affects inextirpable situation, aluminium lamination is provided with below EVA separation layer, like this, carry out the impact of other different types of metal pair label alternative with the impact of a kind of fixing metallic aluminium on label, ensure that and no matter be attached on that metal, the impact being subject to metal is all consistent, be the impact of aluminium, improve stability and the consistance of tag performance; Moreover, in order to anti-interference and consistance, with the addition of aluminium lamination and thicker EVA separation layer, make the more difficult fragmentation of label like this, for overcoming this drawback, having marked easily separated region by many group tool marks, having achieved the destruction of substrate; In addition, intention is pure especially often to organize the design of tool marks adhesion point position, many groups constitute the easily separated region of rhombus as 4 groups of tool marks, if mentality of designing conveniently, often group is complete through tool marks, adhesion point is arranged on the head and end of the tool marks often organized, on the summit in namely four corners of diamond-shaped area, but the invention adhesion point is arranged on the mid point of rhombus four edges, find in practical application, design the probability that easily separated region and neighboring area depart from when this position to significantly improve, even achieve very probability and depart from; Finally, the program have also been devised the facial tissue layer that fragile paper is formed, and is convenient to the character pattern of printing or printed label, meets packaging needs.
