Embodiment
In order that the purpose, technical scheme and advantage to be invented are clearer, below in conjunction with the embodiment of the present invention
Accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is invention
Part of the embodiment, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not having
The every other embodiment obtained on the premise of making creative work, belongs to the scope of protection of the invention.
As depicted in figs. 1 and 2, the present invention provides a kind of flexible anti-metal RFID embodiment.
The flexible anti-metal RFID includes：Metal level 1, separation layer 2 and it is packaged with antenna chip and and antenna
The antenna stack 3 of the RFID antenna of chip electrical connection, wherein metal level 1, separation layer 2 and the superposition of the sequence from low to uper part of antenna stack 3, institute
State and adhesive is provided between metal level 1 and separation layer 2, separation layer 2 and antenna stack 3, printable layer 5 is provided with the antenna stack 3.
Specifically, the metal level 1, separation layer 2, antenna stack 3 and printable layer 5 are relatively thin sheet so that they are folded
Thickness is smaller after adding return, has preferable flexible member.Lead between the metal level 1, separation layer 2, antenna stack 3 and printable layer 5
Adhesive is crossed to be adhesively fixed.The antenna stack 3 forms RFID antenna using on sheet metal by etching mode, and sets
Antenna chip, chip is set to form electric pathway with RFID antenna.
The outside of metal level 1 is provided with the adhesive layer 4 for being used for fixing electronic tag as needed.In order to increase adhesive layer with
Metal level bonding strength, increase and the aperture 11 of the bonding force of adhesive layer 4 are distributed with the metal level 1, due to setting adhesive layer 4
When, aperture 11 can allow part adhesive material to enter, and can increase its bonding force with the surface of metal level 1.The adhesive layer 4 is another
Simultaneously, i.e., surface also has cohesive, is easy to RFID being directly anchored on article.
The separation layer 2 can isolate to signal between metal level 1 and antenna stack 3, avoid receiving RFID antenna
Signal disturbed.
During the manufacturing, flexible anti-metal RFID is batch production, is usually an a roll of volume state.
In use, need continuously print the letter such as label symbol and bar code of needs on the printable layer on RFID surface
Breath.After the completion of printing, RFID is removed, by the adhesive layer set on metal level, it is fixed with product.While by
Metal level is just carried in electronic tag itself, has just been examined during its designing antenna and has been filtered use in band metal object environmental factor, because
And the influence that use environment is read to electronic tag can be reduced.
As shown in figure 3, the present invention is on the basis of above-described embodiment, it is also proposed that another embodiment, by the antenna stack
The inside bending in one or both sides, folding part 31 is formed in the upper surface of antenna stack 3, part RFID antenna is distributed with the folding part 31, and
On the folding part 31 on RFID antenna and antenna stack 3 other RFID antennas into complete RFID electric tag antenna, the setting can
Effectively to increase the receiving area of RFID antenna length and RFID antenna.Simultaneously when the both sides of antenna stack 3 all extend folding shape
Into two folding parts 31, two folding parts 31 can be partially or fully overlapping, and antenna stack 3 can be made to form similar loop aerial, can be with
Improve the sensitivity of small area antenna.Its structure is same as the previously described embodiments, repeats no more.
As shown in figure 4, the present invention provides a kind of flexible anti-metal RFID preparation method, this method includes：
S10 steps, base material composite steps, laminated structure fixed metal layer, separation layer and antenna substrate layer, form RFID electricity
Subtab base material, RFID base material is fixed on laying by adhesive layer.
S11 steps, antenna stack making step, multiple RFID antennas are formed on antenna substrate layer by etch process, then
Antenna chip and RFID antenna are formed into electric pathway.
S12 steps, mill cut step, RFID base material mill are cut independent RFID electronics marks are formed on laying
Label.
Specifically, in batch production, metal level is bonded on laying for one by adhesive layer, then surface is set
There is a separation layer of adhesive and after metal level is adhesively fixed, antenna substrate layer is fixed with separation layer, formed with adhesive layer
RFID base material.The antenna substrate layer of the RFID base material the superiors is pointed to, by etch process in antenna
Multiple RFID antennas are formed on substrate layer, and antenna chip and RFID antenna are formed into electric pathway.Due to RFID system
Using batch production when making, thus multiple RFIDs are continuously coupled state, thus cut step using mill, are made each
RFID separate state, and be at least adhesive layer and RFID base material thickness sum in the depth that mill is cut, i.e.,
Guarantee mill and switch to laying surface, when in use can so separate each independent RFID from laying.
Simultaneously because adhesive layer is less than its bonding force with metal level, when removing RFID, metal with laying bonding force
Layer can have adhesive layer all the time, be easy to fix RFID.The laying can use with adhesive layer separation material, specifically
Material can be not construed as limiting, and can use existing material, such as PVC or strippable paper.
Just examined because electronic tag itself just carries metal level, during its designing antenna and filtered use in band metal object ring
Border factor, thus the influence that use environment is read to electronic tag can be reduced.
After the completion of antenna stack making step, printable layer can be provided with the RFID substrate upper surface,
So can be in RFID printout surface related bar code and information.
As needed, the antenna stack making step also includes two inside bendings in side of antenna stack, in antenna stack 3
Upper surface forms folding part 31, and each folding part is provided with RFID antenna, and the antenna of the RFID antenna and other parts can be with antenna core
Piece forms electrical connection.Above-mentioned folding part 31 sets the receiving area that can effectively increase RFID antenna length and RFID antenna.Together
When antenna stack 3 both sides all extend folding formed two folding parts 31, two folding parts 31 can be partially or fully overlapping, can make day
Line layer 3 forms similar loop aerial, can improve the sensitivity of small area antenna.Its structure is same as the previously described embodiments, no
Repeat again.
In order to increase the adhesive effect between adhesive layer and metal level, increasing is distributed with the layer on surface of metal contacted with adhesive layer
Add the aperture with bonding strength.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
The present invention is described in detail, it will be understood by those within the art that：It still can be to foregoing each implementation
Technical scheme described in example is modified, and person carries out equivalent substitution to which part technical characteristic, and these modifications are replaced, and
The essence of appropriate technical solution is not set to depart from the spirit and scope of various embodiments of the present invention technical scheme.
