Technical Field

[0001] The utility model relates to the technical field of RFID tags, in particular to a UHF flexible anti-metal tag. Background Art

[0002] UHFRFID (ultrahighfrequencyradiofrequencyidentification), that is, ultrahigh frequency wireless radio frequency tag, ultrahigh frequency RFID technology has the characteristics of being able to read multiple tags at one time, strong penetration, multiple read and write, large data storage capacity, low cost, small size, easy to use, high reliability and life, etc., and ultrahigh frequency wireless radio frequency tags have been widely used in various industries, such as fixed asset management, management in warehousing and logistics transportation, and supervision and management of goods or vehicles by customs. The application of ultrahigh frequency electronic tags is very wide, and the environment is changeable. Many managed items are metal objects, such as cars, containers, computers, metal shelves, etc. However, when ordinary wireless radio frequency tags are placed on metal surfaces, the reading distance of wireless radio frequency tags will be greatly reduced or even cannot be read.

[0003] In recent years, some concepts and achievements of flexible anti-metal tags have emerged. Although these achievements have improved traditional tags to a certain extent, the flexible material causes the tag bending angle to exceed the yield limit of the internal antenna layer, which can easily cause damage to the antenna layer and the tag. For this reason, we propose a UHF flexible anti-metal tag. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the bending angle of the tag caused by the flexible material can exceed the yield limit of the internal antenna layer, which easily causes damage to the antenna layer and the tag. The utility model provides a UHF flexible anti-metal tag.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A UHF flexible anti-metal tag comprises an antenna layer, the back side of the antenna layer is fixedly connected to a foam isolation layer, the rear side of the foam isolation layer is fixedly connected to an elastic connection layer, the rear side array of the elastic connection layer is fixedly connected to a plurality of metal conductive sheets, the plurality of metal conductive sheets are metal plates with chamfers cut on all four sides of the rear side, and an adhesive layer is arranged on the rear side of the metal conductive sheets.

[0007] Furthermore, a surface layer is attached to the front side of the antenna layer, and a printed layer is coated on the front side of the surface layer.

[0008] Furthermore, the elastic connection layer includes a hard rubber center block in the center and an elastic rubber film at the edge, and a plurality of elastic ropes are evenly embedded in the elastic connection layer. The front side of the hard rubber center block is glued and fixed to the back side center of the foam isolation layer.

[0009] Furthermore, the adhesive layer includes a plurality of foam double-sided adhesive tapes, and the rear sides of the plurality of metal conductive sheets are hingedly fixed with the foam double-sided adhesive tapes.

[0010] Furthermore, a release paper is attached to the rear side of the plurality of foam double-sided adhesive tapes.

[0011] The beneficial effects of the utility model are as follows:

[0012] 1. The utility model sets an antenna layer, and the antenna part in the antenna layer is a conductive material, which can be made of metal materials such as aluminum, copper, iron, graphite, carbon, silver, etc., so as to ensure the conductivity of the antenna and achieve the characteristics of softness and bendability. The antenna of this layer is designed in a decoupling manner, and the impedance conjugation maximizes the reading distance of the tag. The foam isolation layer is set, and the foam isolation layer can support and fix the antenna layer, and the foam isolation layer separates the antenna layer and the metal conductive sheet to form a decoupling structure, which ensures the reading of the tag on the metal surface. Through the set elastic connection layer and the metal conductive sheet, the metal conductive sheet can be fixed on the back side of the elastic connection layer through the chamfer of the back side, so that the adjacent metal conductive sheets can be clash when flipped through the chamfer, limiting the flipping angle of the adjacent metal conductive sheets, which can avoid the circuit in the antenna layer from being damaged by overbending, and ensure the normal use of the antenna layer. At the same time, the flipping of the adjacent metal conductive sheets can ensure the bending performance of the tag, which is convenient for the tag to be attached to the curved surface. The set adhesive layer facilitates the attachment and fixation of the tag.

[0013] 2. The utility model sets an elastic rubber mold so that the periphery can be stretched and extended outward, so that the metal conductive sheet on the rear side is dispersed, which is convenient for the metal conductive sheet to be dispersedly bonded and fixed on an uneven surface. When the metal conductive sheet is bonded on an irregular surface, the elastic connecting layer can be stretched to improve the deformation ability, thereby improving the bonding and fixing effect.

[0014] 3. The utility model provides multiple foam double-sided adhesive tapes. The compressibility of the foam double-sided adhesive tapes facilitates the lamination of the back side of the foam double-sided adhesive tapes with uneven surfaces, thereby improving the bonding and fixing effect of the metal conductive sheet. In addition, the multiple independent foam double-sided adhesive tapes can be fixed in coordination with the deformation of the elastic connecting layer. BRIEF DESCRIPTION OF THE DRAWINGS
