Definitions
- the invention relates to a resonance tag according to the preamble of claim 1.
- Resonance labels are mainly used in retail, where they serve both for labeling goods and as a theft protection.
- the resonance labels attached to the goods must be deactivated at the cash register, so that no false theft alarm is triggered when the sales area is left. This deactivation must therefore be carried out in such a way that it is permanent and secure; the deactivation process must not be problematic in terms of trade supervision or postal matters, but must be simple and reliable to carry out.
- Deactivation also takes place here by blowing a fuse that is provided in the deactivation resonance circuit. In this way, possible false alarms that can arise if the frequency of detection and deactivation are the same are switched off.
- the dimensioning of the deactivation circuit containing the fuse takes place from the point of view of keeping the longitudinal impedance of the induction coil and capacitor as low as possible in order to have the majority of the voltage drop available to blow through the fuse link.
- the induction coil must be as small and the capacitor as large as possible.
- the size of the capacitor causes both an undesirable increase in the cost of production and an impractical increase in the size of the resonance label itself.
- a fundamentally different way of deactivating a resonance tag is based on the fact that - with a correspondingly high potential - the dielectric that lies between the two conductor circuits on the two sides of the resonance tag causes a breakdown in order to achieve that that is necessary for the deactivation Potential may be as low as possible, the dielectric layer was kept particularly thin, for example.
- US-A-4,567,473 describes a resonance label which has a notch in the dielectric between the capacitor plates.
- the deactivation takes place at or near the resonance frequency with sufficient energy so that there is a breakdown at this point determined by the notch through the dielectric.
- metal should accumulate along the breakthrough section and thus a permanent short-circuit section, as a result of which the resonance properties of this resonant circuit are destroyed.
- producing a precisely defined notch in a thin dielectric layer proves to be relatively complex and difficult. It has therefore been proposed instead to bring the two capacitor plates closer together at certain points by pressure, and thus to thin the dielectric between the plates.
- difficulties have arisen in manufacturing practice which result above all from the small, required tolerances. Smallest fluctuations in thickness and material impurities in the dielectric often do not allow the desired, defined thinning to be achieved.
- EP-AI-0285559 Another variant is described in EP-AI-0285559, according to which at least one hole is provided between the capacitor plates and through the dielectric. A locally limited but defined inhomogeneity is thus built in, at which the breakdown between the capacitor plates can take place.
- the required geometry during production can be controlled much better here, since no thickness tolerances for the dielectric have to be observed when a hole is made.
- All described deactivation variants which are based on some kind of thinning of the dielectric (a further variant is also described in US Pat. No. 4,689,636) are additionally subject to the disadvantage that the resonance etiquette as such is ge at precisely these diluted points ⁇ weakens and therefore - e.g. with bending stress - their function is endangered.
- DE-A1-3732825 and DE-A1-3826480 describe resonance labels, in which one conductor spiral is covered by a deactivation conductor, an insulation layer being arranged between the conductor spiral and the deactivation conductor. In the case of an energy signal with a suitably selected energy, this insulation layer becomes electrically conductive. This deactivates the resonance label.
- These resonance labels have several - at least two - defined breakdown points. Since only a part of the induction coil fails during this deactivation process, frequency offsets and thus the triggering of false alarms can result.
- the invention is therefore based on the object of designing a resonance label in such a way that it can be safely and permanently deactivated and can also be produced in a cost-effective and clearly defined manner. This is done by the features described in the characterizing part of claim 1. It is thereby achieved, in particular, that a resonance label with such a target breakdown point is immanent in a geometry that is easy to control, which enables defined production within small tolerances, which is also inexpensive.
- the target breakdown point is preferably covered by a dielectric or an insulator, which on the one hand provides protection against flashovers from the surrounding air, and on the other hand permanent deactivation, be it in the form of a permanent short-circuit path or in the form of a through-circuit Breakdown of a dielectric self-generated, permanently low-resistance.
- the conductor areas adjacent to each other at the target breakdown point should be in one distance as close as possible from each other. This distance can now, for example, be precisely cut from a continuous conductor connection with the aid of lasers, or, if this process step, which requires a very high degree of precision, is not desired, can be achieved, for example, by using photo etching technology in the usual way applied conductors are carried out in the same method step at a point determining the target breakdown point spaced apart.
- a layer of conductive material can be provided between the conductive regions, which is protected against at least one of the conductor regions and preferably also against the insulating carrier layer by a thin layer of insulating material is delimited.
- the electrical conductivity of this conductive material can be lower than the conductivity of the conductive areas.
- a relatively low-resistance resistor layer with a resistance of, for example, a maximum of 100 ohms can also be provided. Reliable deactivation is also possible with resistors up to a maximum of 1000 ohms.
- a wide variety of materials and types of application are possible, depending on the electrical properties of the resonant circuit and the dimensioning of the target breakdown point.
- an epoxy resin mixed with aluminum particles can be spotted on thin - in the order of a few microns -, an aluminum or other suitable metal layer can be evaporated, or a resistance paste based on noble metal can be printed on, corresponding to the thick-film technique.
- the thickness of the insulating layer to be applied can be seen depending on its material properties.
- this conductive or low-resistance material covering the desired breakdown point from the adjacent conductor areas and preferably also from the insulating carrier layer is preferably done by a thin layer of insulating material.
- This can, for example, dripped or printed or also used by hot stamping lacquer or ink layer, or it can be formed by the oxidized edge zones of the conductor itself;
- an insulating - for example UV-curable - color layer, preferably twice, can also be printed between the two conductive regions, to which, somewhat offset, a conductive - preferably also UV-curable - color layer, in particular also twice, is printed.
- This conductive paint layer is in conductive contact with one of the two conductive areas, whereas it is spaced from the other conductive area by the insulating paint layer. Since different layers of color, each 2 ⁇ each, can be applied in one operation on a multicolor printing machine, the manufacturing process is considerably simplified. With two prints each, layer thicknesses of 4 ⁇ are achieved.
- a cover of the resonance label on the side having the target penetration point by a film which can be made of paper, for example, and thus at the same time can be used to record the goods identification, price or the like, protects the label and the short circuit bridge mechanical stress and - possibly - subsequent breakage. As a result, the short-circuit bridge remains permanent and safe.
- FIG. 1 shows a longitudinal section through a resonance label according to the invention
- Fig. 2 and 3 the top and bottom of this resonance label; and 4 shows a longitudinal section through another variant of the resonance tag according to the invention.
- the resonance label 1 shown in cross section in FIG. 1 has on its two sides 2 and 3 conductive regions separated by an insulating carrier layer 4, which form an induction coil 5 and a capacitor 6 in a manner known per se.
- the two capacitor plates 6a and 6b are separated by the carrier layer 4, which consists, for example, of polyethylene.
- Two contact lugs 7a and 7b on the top side 2 and bottom side 3 of the resonance tag 1 are conductively connected to one another, for example by crimping, through the carrier layer 4 (connection point 11a).
- One contact lug 7a is connected to a capacitor plate 6a, the other contact lug 7b to the turns of the induction coil 5.
- Two further contact lugs 7c and 7d are formed on the two capacitor plates 6b and 6a.
- One of the two contact lugs 7c is in direct electrical connection with one capacitor plate 6b, while a distance a is provided between the other contact lugs 7d and the adjacent capacitor plate 6a.
- This distance a should be fractions of a ⁇ , and should preferably be in the range of 0.1-1 ⁇ .
- the two contact lugs 7c and 7d are electrically connected to one another in the same way as the two other contact lugs 7a and 7b through the carrier layer 4 (conductive connection points 11b and 11a, respectively).
- This dielectric 9, which covers the target breakdown point 8 can be one that differs from that of the carrier layer 4. have permittivity; on the other hand, in order to minimize any possible contact surface problems, it could be advantageous to provide carrier layer 4 and dielectric 9 made of the same material, that is to say with the same dielectric constant. To set up a particularly permanent short-circuit bridge, local coverage of the target breakdown point 8 alone is sufficient; In terms of manufacturing technology, a complete covering or covering of the entire upper side 4 of the resonance tag 1 with a dielectric or insulator layer may be advantageous.
- Another possibility of deactivating the resonance tag 1 is to provide as material for the dielectric 9, which covers the desired breakdown point 8, one which breaks through at a correspondingly high, induced breakdown voltage and into a permanently low-resistance one Resistance passes.
- the target breakdown point 8 is cut from a short conductor piece 10, preferably by means of a laser.
- the dielectric 9 completely covers the target breakdown point 8, the adjacent conductive areas on the capacitor plate 6a, conductor piece 10, contact tab 7d and also the corresponding areas of the carrier layer 4 within a certain radius.
- the conductive connection points 11a 'and 11b 1 each connect the contact lug pairs 7a and 7b or 7d and 7c on the top 2 and bottom 3 of the resonance tag 1.
- FIG. 3 shows the corresponding arrangement of an induction coil 5 and a second capacitor plate 6b with the associated contact tabs 7b between 7c and their conductive connection points 11a "or 11b" on the underside 3 of the resonance chain 1 see.
- FIG. 4 Another variant of a deactivatable resonance tag is shown in FIG. 4, which is characterized by a precisely defined target breakdown point 8 ".
- the distance a" between contact tab 7d “and capacitor plate 6a” is between a few tenths of a millimeter and approximately one Millimeters tall.
- An insulating layer 14 is arranged between the two conductor regions 6a "and 7d", and partly also on them, which is preferably a UV-curable, twice-printed ink layer of approximately 4 ⁇ m thick.
- an electrically conductive layer 15 which is in electrically conductive contact with one of the two conductive regions, here 7d ", whereas it is insulated from the other conductor region, here the capacitor plate 6a", by the insulating layer 14 lying in between .
- This resonance label is deactivated as described above; the breakdown takes place between the conductive layer 15 and the capacitor plate 6a ".
- the conductive layer 15 is preferably a likewise UV-curable, in particular printed twice, color layer.
- the application of two color layers, an insulating 1 and a conductive 15, can be done in a single operation on a printing press, the thickness of the ink layer being, for example, approximately 4 ⁇ .
- the electrically conductive layer 15 can consist of an electrically conductive material whose electrical conductivity is lower than that of the adjacent conductor regions 6a "and 7d", but high relative to an insulator or dielectric.
- an electrically conductive material whose electrical conductivity is lower than that of the adjacent conductor regions 6a "and 7d", but high relative to an insulator or dielectric.
- epoxy resin mixed with aluminum particles, or also resistance pastes known from thick-film technology, which are based on a noble metal, as well as vapor-deposited aluminum or other metal layers are conceivable as such conductive materials for layer 15.
- the delimiting insulating layer 14 can be an insulating lacquer or ink layer, or it can also be formed simply by oxidation of the free sides of the conductor regions 6a "and 7d".
- the capacitor 6 is arranged outside the induction coil 5. Self-evident In a known manner, the capacitor could also be provided positioned within the induction coil. In a known manner, more than one induction coil, more than one capacitor can be formed on the top and / or bottom of the resonance tag.
- the arrangement of the target breakdown point 8 on the upper capacitor plate 6a according to FIG. 2 is only one exemplary possibility of the resonance tag according to the invention.
- the invention also includes any other possibility of providing the target penetration point, provided that it lies between two conductive areas on one of the two sides of the resonance label. Likewise, more than one target breakdown point can be formed, be it on one of the two sides or also on both sides.
- the durability of the deactivation is essential.
- the target puncture point in particular should be protected by an additional film to be applied, which covers the entire resonance label.
- This film (not shown), which can also be made of paper, for example, then prevents the resonance tag from being subsequently broken and destroyed in the event of mechanical stress.
