Problems solved by technology

[0005] The purpose of the present invention is to provide a high-precision radio frequency soft label, which mainly solves the technical problem of the existing high-precision soft label that the wires constituting the capacitance area are equal in width to the wires in other parts, which is not conducive to increasing the inductance of the wires. And on this basis, the capacity of the capacitance area can be increased, and the accuracy of the radio frequency soft label can be further improved, which is beneficial to the work of anti-theft and anti-counterfeiting

Embodiment 2

[0027] A high-precision radio frequency soft label. The base layer of the label is composed of an insulating film layer and conductive layers respectively attached to the front and back of the insulating film layer. The conductive layer is composed of capacitor wires, coil wires and decoding points. In the decoding circuit, the capacitor wire is located on the periphery of the coil wire, and the width of the capacitor wire and the coil wire gradually decreases from outside to inside. The insulating film layer and the conductive layer together constitute the base layer of the label, and a hard insulating material layer is arranged on the base layer. The hard insulating material layer has a pre-processed breaking mark, and the breaking mark has an intersection angle with the circuit on the conductive layer.

[0028] The structure of Example 2 is based on Example 1 with a snap-off non-revivable structure added. After the label is used, the label can be broken through the breaking...

Embodiment 3

[0034] A high-precision radio frequency soft label, the base layer of the label is composed of an insulating film layer and conductive layers respectively attached to the front and back of the insulating film layer. The insulating film layer is a polyethylene film layer with a thickness of 0.015±0.001mm. The conductive layer has a decoding circuit composed of a capacitor wire, a coil wire and a decoding point. The capacitor wire is located at the periphery of the coil wire. The width of the capacitor wire and the coil wire gradually decreases from the outside to the inside. greater than the positive capacitance lead. Both the front conductive layer and the back conductive layer of the label have capacitor wires and coil wires, thereby forming a soft label with double-sided circuits. Through this structure, the inductance of the coil part can be further increased, and the precision of the product can be improved.

Abstract

A high-precision soft tag of radio frequency is prepared as forming countermark base layer by the first insulation film layer and conductive layer stuck separately on the first and second surface of insulation film layer, setting a decoding circuit formed by capacity and wire as well as decoding point on said conductive layer, setting capacity at periphery of coil formed by wire. It features that the width of capacity wire and coil wire is decreased gradually from outside to inside.

Description

Technical field: [0001] The invention relates to the technical field of anti-theft and anti-counterfeiting devices, in particular to a high-precision radio frequency soft label. Background technique: [0002] At present, there are many anti-theft alarm devices on the market, including mechanical anti-theft alarm devices and electronic anti-theft alarm devices. [0003] Based on the above situation, some operators have invented a secure electronic soft label that cannot be revived after decoding. It is generally embedded in a paper hang tag. The material of the product is soft and it is not easy to be found when used. The structure of the above-mentioned electronic soft label is that a conductive layer is attached to the first surface and the second surface of an insulating film layer, and the conductive layer has a decoding circuit composed of a capacitor, a wire, a decoding point, etc.; wherein, the capacitor It is located in the middle of the coil composed of wires, and t...
