Description
Technical field
The present invention relates to a kind of electronic tag, be specifically related to a kind of anti-theft electronic soft label.
Background technology
In recent years, conveniently client's free choice of goods, a lot of megastore all adopts the sales mode of open-type counter, this mode not only improve market shopping environment, make things convenient for customers from main separation, and the profit of businessman can also be increased.But the safety of commodity and the requirement of scientific management are also correspondingly improved and causes the concern of businessman, and traditional manpower is thief-proof is replaced by high-tech anti-theft electronic label gradually owing to there is the shortcoming that cost is high and efficiency is lower, anti-theft electronic label is attached on commodity, when these commodity are stolen by stealer intention, during by sense channel, detect antenna and the signal that commodity are launched can be detected, and send chimes of doom, thus play antitheft effect.If paid the commodity of money, only needing to make label decode inefficacy through dedicated decoders can normal through sense channel.
Soft label is a large class of anti-theft electronic label, existing anti-theft electronic soft label is mainly made up of base paper, multi-turn coil, the chip being positioned at described multi-turn coil, non-drying glue layer, adherent layer, described multi-turn coil and described chip are connected through conductor and form resonant circuit, and conductor is connected with tie point.Authorization Notice No. is the electronic tag that the Chinese invention patent of CN201465153U provides a kind of rectangle multi-turn planar coil, circle core electric capacity composition, the Chinese invention patent that Authorization Notice No. is CN201465156U also provides a kind of electronic tag be made up of pentagon multi-turn planar coil, rectangular capacitive, and this kind of label all has low cost of manufacture, is convenient to the advantages such as stickup.In addition, a kind of high-precision radio frequency soft tag is disclosed in Chinese invention patent (Authorization Notice No.: CN100423026C), the basic unit of this label is made up of the conductive layer that an insulating film layer and insulating film layer first surface and second surface are sticked respectively, described conductive layer has the decoding circuit of capacitive lead, winding wire, solution code-point formation, capacitive lead is positioned at winding wire periphery, the width ecto-entad of this capacitive lead and winding wire reduces gradually, to a certain degree can improve the capacity of capacitive region.
But but there is following problem in existing anti-theft electronic label:
1, because multi-turn lines are thin and the number of turns is many, therefore in process of manufacture, easily produce the problem such as trachoma, broken string, therefore correspondingly increase subsequent technique and control difficulty, reduce production yield;
2, traditional electronic tag is due to containing inductance and electric capacity two parts, the signal produced due to less radio-frequency is more weak, electronic tag transmits cannot through-fall, hydrous matter etc., therefore signal is easily by the shielding such as water, hydrous matter, so sense channel is not easy to capture signal, bring opportunity to stealer;
3, these labels do not have the function of anti-microwave, and it placed in micro-wave oven with food because of carelessness, likely produce spark, the heat of generation even may cause on fire;
4, conventional anti-theft electronic label generally contains toxic ingredient or easily produces noxious material after the heating, is not suitable in the antitheft purposes of food.
Summary of the invention
The object of the invention is to provide a kind of anti-theft electronic soft label, by the improvement of structure, electronic soft label capacitive region capacity is increased, the service precision usurping soft label is prevented in effective raising, to produce signal penetration capacity strong, the absorption to signal such as anti-sealing or hydrous matter, thus serve the effect of anti-shielding, enhance anti-theft feature, widen usable range, owing to have employed individual pen, or 4 structures in capacitor shield coil district within circle, more traditional above telefault of 7 circle compares, decrease in multi-turn coil production process and easily occur trachoma, the problems such as broken string, also reduce subsequent production technology difficulty and improve production yield, the conducting of bridge contact also makes total capacitance coil area serve the effect of inductance and electric capacity simultaneously, in addition, this electronic soft label also has anti-microwave and nontoxic performance, safe and reliable, be applicable to the antitheft of foodstuff.
For achieving the above object, the technical solution used in the present invention is: a kind of anti-theft electronic label, by dielectric layer be fitted in the front side conductive layer of dielectric layer both sides respectively and backside conductive layer forms, the front capacitive region that described front front side conductive layer comprises front capacitor shield coil and is connected with described front capacitor shield coil, the composition of front capacitor shield coil is built by 2 turn coil that (size according to label or the needs for system works scope can increase more multi-turn number, mostly be most 4 circles), the back side capacitive region that described backside conductive layer comprises back side capacitor shield coil (backside loop total amount is 1 circle) and is connected with described back side capacitor shield coil, described front capacitor shield coil and described back side capacitor shield coil are relative between two also forms total capacitance coil area jointly with middle described dielectric layer, described total capacitance district is provided with solution code-point, it is characterized in that: described total capacitance district is provided with transverse line, described total capacitance district folds along described fold line toward capacitor shield coil district, front or capacitor shield coil district, the back side and fixes and forms double-layer capacitance district, front, described total capacitance district is a circle or multi-turn (being not more than 4 circles) coil, backside loop is one-turn coil, described total capacitance district is provided with bridge contact.Therefore the present invention not only has double-layer capacitance district, but also there is another capacitive region that total capacitance coil area forms, simultaneously because front capacitor shield coil and back side capacitor shield coil conducting are defined telefault by bridge contact, therefore total capacitance coil area is with the effect of electric capacity and inductance.
In technique scheme, side, capacitive region lower end, described front is connected with described front capacitor shield coil by bonding pad, front, side, capacitive region lower end, the described back side is connected with described back side capacitor shield coil by bonding pad, the back side, bonding pad, described front and bonding pad, the described back side lay respectively at the both sides of described total capacitance coil area, bonding pad, described front is provided with the front bridge joint hook of hollow out, and bonding pad, the described back side is provided with the back side bridge joint hook of hollow out.
In further technical scheme, described front bridge joint hook and described back side bridge joint are hooked on described total capacitance coil area and enclose formation bridge region mutually, described bridge contact is located on described bridge region, due to the existence of bonding pad, front, bonding pad, the back side and bridge contact, make total capacitance coil area and total capacitance district or double-layer capacitance district can form an interconnective entirety.
In technique scheme, described dielectric layer comprises the one in polypropylene film, polyethylene film.
In technique scheme, described conductive layer is aluminium foil.
Due to the utilization of technique scheme, the advantage that the present invention compared with prior art has is:
1, due to the improvement by structure in the present invention, be provided with double-layer capacitance district, total capacitance coil area also has the function of electric capacity simultaneously, therefore infinitely expands the effect of electric capacity, effectively improves the anti-service precision usurping soft label;
