Problems solved by technology

[0005] The purpose of the present invention is to provide a high-precision radio frequency soft label to solve the problem of existing high-precision soft labels. The wires constituting the capacitance area are equal in width to the wires in other parts, which is not conducive to increasing the capacity of the capacitance area and increasing the inductance of the wires. A large number of technical problems, further improving the accuracy of the radio frequency soft label, is conducive to anti-theft and anti-counterfeiting work

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 first surface and the second surface of the insulating film layer. The conductive layer is equipped with capacitors, wires and decoding A decoding circuit composed of dots, the capacitor is located on the periphery of the coil composed of wires, and the width of the capacitor wire and the coil wire gradually decreases from the outside to the 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 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 brok...

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 on the first surface and the second surface 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 capacitors, coil wires and decoding points. The capacitor is located at the periphery of the coil composed of wires. The widths of the capacitor wires and the coil wires gradually decrease from outside to inside. The width of the back capacitor wires No larger 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...
