Abstract
The utility model discloses a prevent tearing open electronic tags, be in including flexible parent metal, distribution antenna on the substrate inverts the chip of being connected with the antenna, antenna and chip formation closed loop, the substrate has a plurality of incisions through the cutting of CO2 laser machine, and has at least an incision one end to have the opening, notch depth more than or equal to 90% of the base material thickness. Prevent tearing open electronic tags, it is succinct to have the structure, the cost of manufacture is low, and prevent tearing open effectual, convenient to use's characteristics.
Description
Technical field
The utility model relates to electronic tag field, particularly a kind of anti-demolition electronic tags.
Background technology
Anti-demolition electronic tags generally adopts rupture diaphragm to work it out, although serve tamper effect, but break because rupture diaphragm is as easy as rolling off a log, so rupture diaphragm is made in the process of antenna, because antenna wire diameter is very little, be easy to cause broken string, thus cause yield rate very low, generally the highlyest can only reach 60%.Therefore, the anti-demolition electronic tags manufacturing process waste of which is very huge, makes the cost of this anti-demolition electronic tags very high, limits it and can only be applied on high-end product, as on high-end wine, high-end clothes, and cannot widespread use.
Utility model content
The purpose of this utility model is to provide a kind of anti-demolition electronic tags, solves existing anti-demolition electronic tags complex structure, the problem that cost of manufacture is high.
In order to achieve the above object, the utility model adopts following solution:
A kind of anti-demolition electronic tags, comprises flexible parent metal, distribution antenna on the substrate, the chip be connected with antenna upside-down mounting; Described antenna and chip form closed loop; Described base material is cut with multiple otch by CO2 laser machine, and has at least a kerf one end to have opening; Described notch depth is more than or equal to 90% of described base material thickness.
Further, the shape of described antenna is circular or square or rectangle.
Further, described otch is triangle or square or line style.
Compared with prior art, the advantage of technical solutions of the utility model is.
Accompanying drawing explanation
Fig. 1 is anti-demolition electronic tags structural representation described in the utility model.
Fig. 2 is anti-demolition electronic tags schematic cross-section described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.
Shown in composition graphs 1 and Fig. 2, a kind of anti-demolition electronic tags, comprises flexible parent metal 10, distribution antenna 20 on the substrate, the chip 30 be connected with antenna 20 upside-down mounting; Described antenna 20 forms closed loop with chip 30; Described base material 10 is cut with multiple otch 11 by CO2 laser machine, and has at least a kerf 11 one end to have opening; Described otch 11 degree of depth is more than or equal to 90% of described base material 10 thickness.
Described base material 10 is the flexible materials such as PET or PVC.
20, described antenna adopts aluminium foil or Copper Foil preparation to be formed, and is adhesively fixed on described base material 10 by glue 40.The coiling shape of described antenna 20 can be circular, square or rectangle, can be even other figures.The interior zone that described antenna 20 surrounds is for settling chip 30.The input end of described chip 30 is connected with the initial and end of output terminal with described antenna 20, jointly forms closed loop configuration.
Described otch 11 can be triangle, square or linear, and described otch 11 degree of depth is more than or equal to 90% of described base material 10 thickness.That is, base material 11 has soon cut off by the otch 11 of formation substantially, makes when dismantling label, only need dynamics gently namely can fall base material to tear, and then by antenna damage, electronic tag was lost efficacy, cannot reading writing information, thus reach the effect preventing electronic tag to be disassembled.
Above-mentioned otch 11 adopts the cutting of CO2 laser machine to be formed.CO2 laser machine maximum effect to destroy plastic products, and to metal without any effect.Therefore, by regulating the laser intensity size of CO2 laser machine, setting thinner laser beam, base material 10 is cut, form otch.The degree of depth of otch is with till cutting off base material 10 soon.
Anti-demolition electronic tags described in the utility model, by base material being designed to the structure with multiple otch, and notch depth reaches more than 90% of base material thickness, the base material originally with very obdurability is become and is very easily torn destruction.During use, only need cover glue at this anti-demolition electronic tags back side and just this electronic tag can be attached to and want on false proof article, tear the antenna that namely label can destroy inside open carry out destroying this electronic tag as long as go to tear, finally play the effect of tamper.Anti-demolition electronic tags described in the utility model, have simple for structure, cost of manufacture is low, and easy to use, the feature that tamper is effective.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; can make possible variation and amendment, the scope that therefore protection domain of the present utility model should define with the utility model claim is as the criterion.
Claims (3)
