Abstract
The utility model provides a novel anti metal label of RFID, it is from last metal sheet, RFID label circuit layer, dielectric layer and the metal sheet down of having included downwards, go up metal sheet, RFID label circuit layer, dielectric layer and down the metal sheet laminating form combination formula label, the antenna of going up metal sheet and RFID label circuit switches on. The utility model discloses having utilized the metal level to improve the tag antenna performance and having been destroyed with the difficult quilt of protection tag antenna, the material can adopt the common material, can realize mass production and its uniformity is good, with low costs. And go up metal sheet, RFID label circuit layer, dielectric layer and down the metal sheet adopt conventional metal column to connect the pressfitting be in the same place, its technology maturation, technology is stable, and the antenna arrange in about between the metal sheet, be favorable to protecting tag antenna, be fit for using in much more more environment.
Description
Technical field
The utility model relates to field of radio frequency identification, particularly relates to a kind of RFID anti-metal tag.
Background technology
Rapidly, application is more and more wider in RFID technique development, in some practice (such as industry, asset management), needs RFID label tag can be used in feature on metal, namely requires that label is very functional, prevent from not in use being destroyed.
RFID label antenna is abutted against the electromagnetic wave receiving certain energy to carry out work, these electromagnetic waves have RFID reader to be sent by reader antenna, metal pair electromagnetic wave has an effect of reflecting, be unfavorable for the normal use of RFID label antenna, the impact overcoming metal pair label is the most important thing researched and developed now.
It is high that current reality uses RID anti-metal tag to there is cost, to phenomenons such as label antenna are exposed.The first as application number be a kind of Broad-band Ceramic anti-metal tag disclosed in the Chinese patent literature of 201410427443.9, its dielectric layer selected is expensive ceramic dielectric, is unfavorable for use in enormous quantities, and this label be unfavorable for produce in enormous quantities.The second is flexible anti-metal electronic tag, and its label antenna is exposed to appearance, is unfavorable for using in technical grade high strength environment.The third as application number be the ultra-high frequency RFID label of a kind of anti-metal disclosed in the Chinese patent literature of 201110422153.1, this label uses electric feedback ring and metal ring antenna-coupled, ring dress antenna need form Kaifeng on first medium layer surface, size because of Kaifeng directly affects the performance of label, and its antenna is exposed to appearance, this RFID anti-metal tag in the consistance of very difficult its product of control, and is unfavorable for producing in enormous quantities.
Summary of the invention
The purpose of this utility model is to provide a kind of novel RFID anti-metal tag, solves the problem that cost is high, label antenna is exposed that existing label exists, and improves the stability of label.For this reason, the utility model is by the following technical solutions:
A kind of novel RFID anti-metal tag, it is characterized in that described RFID label tag from up to down includes sheet metal, RFID label tag circuit layer, dielectric layer and lower sheet metal, the laminating of upper sheet metal, RFID label tag circuit layer, dielectric layer and lower sheet metal forms Combined type label, the antenna conducting of upper sheet metal and RFID label tag circuit.
Described RFID label tag circuit layer comprises RFID label tag circuit and substrate layer, and uses bonding agent to bond between substrate layer and dielectric layer.
Further, described upper sheet metal has one just to the fluting at position, RFID label tag circuit layer visual information place, forms the visual window of label information.
Described upper sheet metal, RFID label tag circuit layer, dielectric layer are also connected by metal column with lower sheet metal and press together, and with the addition of the isolation material making it not conducting between described metal joint pin and upper sheet metal.
Owing to adopting the technical solution of the utility model, the utility model make use of metal level and improves label antenna performance and protection label antenna is not easily destroyed, and material can adopt common material, can realize producing in enormous quantities and its consistance is good, cost is low.And upper sheet metal, RFID label tag circuit layer, dielectric layer and lower sheet metal adopt conventional metal column to be connected to press together; its technology maturation, process stabilizing, and antenna is placed between upper and lower sheet metal; be conducive to protecting label antenna, be adapted at using in more environment.
Accompanying drawing explanation
Fig. 1 is the cut-open view of embodiment provided by the utility model;
Fig. 2 is the explosive view of embodiment provided by the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
With reference to accompanying drawing.RFID anti-metal tag provided by the utility model, from up to down include sheet metal 1, RFID label tag circuit layer 2, dielectric layer 3 and lower sheet metal 4, the laminating of upper sheet metal 1, RFID label tag circuit layer 2, dielectric layer 3 and lower sheet metal 4 forms Combined type label.
Upper sheet metal 1 and RFID label tag circuit layer 2 laminating make sheet metal 1 and RFID anti-metal tag antenna 24 conducting, become a part for RFID anti-metal tag antenna 24, are conducive to label to electromagnetic acceptance and radiation.
Described upper sheet metal 1, RFID label tag circuit layer 2, dielectric layer 3 and lower sheet metal 4 are also connected by metal column 5 and press together, and with the addition of the isolation material making it not conducting between described metal joint pin and upper sheet metal.This makes label antenna not easily be destroyed in the middle of upper and lower sheet metal, and has isolated time sheet metal and metal attachments to the impact of label antenna, thus makes this RFID anti-metal tag be more suitable for multiple environment.
Wherein, described RFID label tag circuit layer 2 comprises RFID label tag circuit 22 and substrate layer 21, and uses bonding agent to bond between substrate layer 21 and dielectric layer 3.
Can the visual information 23 of printed label on the substrate layer of RFID label tag circuit layer 2, upper sheet metal 1 has one just to the fluting 11 at position, RFID label tag circuit layer 2 visual information place, forms the visual window of label information.
