The affinity of the anti-sticking coating and the packaging box paper is smaller than that of the pressure-sensitive adhesive layer 12 and the packaging box paper, so that pressure-sensitive adhesive is ensured to remain on the radio frequency resonant cavity assembly 20 when the radio frequency resonant cavity assembly 20 is peeled off from the package of a express mail, and the radio frequency resonant cavity assembly 20 is convenient to recycle; the release coating has a lower affinity for the pressure sensitive adhesive layer 12 than the pressure sensitive adhesive layer 12 for the label paper, ensuring that no pressure sensitive adhesive remains on the rf cavity assembly 20 when the rf cavity assembly 20 is peeled from the pressure sensitive adhesive layer 12. The invention can treat the pressure-sensitive adhesive remained on the surface of the radio frequency resonant cavity assembly 20 without chemical solvents, is environment-friendly and pollution-free, and can greatly prolong the service life of the radio frequency resonant cavity assembly 20.
When a release coating is selected, the vent 27 extends through the release coating.
3. Radio frequency antenna
The rf antenna 30 includes an antenna coupling end 31 in the middle, and antenna fins 32 located at two sides of the antenna coupling end 31, where the antenna coupling end 31 is used to couple with the rf resonant cavity assembly 20.
The radio frequency antenna 30 can be any one of a PET aluminum foil composite film chemical etching antenna, a PET aluminum foil die-cutting antenna, an aluminum foil die-cutting antenna and a copper wire antenna according to requirements.
The invention can separate the radio frequency resonant cavity assembly 20 from the radio frequency antenna 30, and screen and arrange the recovered radio frequency resonant cavity assembly 20 into the clamping groove, and then install the recovered radio frequency resonant cavity assembly on the new radio frequency antenna 30 again, thereby being convenient for manufacturing the coupled radio frequency tag, realizing the repeated use of the chip, saving the chip and the chip packaging cost and greatly reducing the application cost of the radio frequency tag.
As shown in fig. 4a, 4b and 5, and referring to fig. 1a to 3b, the invention provides a method for manufacturing a radio frequency tag with a recyclable and reusable chip, comprising the following steps:
a1, preparing label face paper 10 with a radio frequency resonant cavity assembly stripping window part 13, and coating pressure-sensitive adhesive on the bottom surface of the label face value to form a pressure-sensitive adhesive layer 12. The label facestock 10 may be thermal paper, cardboard paper, synthetic paper, or the like.
A11, performing image-text printing on the surface of the label facial tissue 10, then forming a pressure-sensitive adhesive layer 12 by adopting a coating process, and processing the pressure-sensitive adhesive layer and the label facial tissue 10 to form tooth-shaped dental floss 131 and cutting-through dental floss 132, thereby finally forming the easy-to-peel radio frequency resonant cavity assembly peeling window part 13.
The area of the stripping window part 13 of the radio frequency resonant cavity assembly is larger than that of the radio frequency resonant cavity assembly 20, the length of the transverse tooth-shaped dental floss 131 is 3-5 mm larger than the transverse width of the radio frequency resonant cavity assembly 20, and the length of the cutting-through dental floss 132 is 3-5 mm larger than the longitudinal length of the radio frequency resonant cavity assembly 20, so that when the stripping window part 13 of the radio frequency resonant cavity assembly is stripped off and stripped from the label facial tissue 10, the radio frequency resonant cavity assembly 20 is ensured to be driven to be separated from the radio frequency antenna 30.
A12, after the label facestock 10 passes through the turning roll, the bottom surface is upwards, the bottom surface printing is implemented, images and texts such as separation identification lines among the printed labels are separated, and then the pressure-sensitive adhesive layer 12 is formed by coating pressure-sensitive adhesive. The pressure sensitive adhesive can be full-page coating and is used for labels with release base paper; if the radio frequency label without release base paper is prepared, the pressure-sensitive adhesive coating width is smaller than the label paper width by 3-4 mm, so that the edge of the label face paper 10 is free of the pressure-sensitive adhesive within the range of 1.5-2 mm, and the label is used for automatic printing and labeling.
A2, discharging the prepared radio frequency resonant cavity assembly 20 from the radio frequency resonant cavity assembly clamping groove assembly 40, and bonding the radio frequency resonant cavity assembly to the pressure-sensitive adhesive layer 12. The rf cavity assembly 20 may select a single turn of rf cavity coil aluminum foil 221 or a dual-turn rf cavity.
After the label is coated with the pressure sensitive adhesive, the radio frequency resonator assembly 20 is pushed out of the pressure sensitive adhesive layer 12 by the card slot discharger 42 of the radio frequency resonator assembly card slot assembly 40, and the radio frequency resonator assembly 20 becomes an integral part of the label and advances in the same way. The radio frequency resonant cavity assembly clamping groove assembly 40 comprises a clamping groove frame 41 with a through resonant cavity assembly space 46 in the middle and a clamping groove discharger 42 positioned at the end part of the clamping groove frame 41, and a clamping groove mounting plate 45 for realizing the mounting of the radio frequency resonant cavity assembly clamping groove assembly 40 is arranged on the outer side of the clamping groove frame 41.
The side wall of the space 46 of the resonant cavity assembly is provided with a convex guide ridge, and the convex guide ridge corresponds to the notch of the radio frequency resonant cavity assembly 20. The raised guide rib comprises a central raised guide rib 43 positioned at the middle of the side wall of the space 46 of the resonant cavity assembly and/or an off-central raised guide rib 44 positioned at the edge of the side wall of the space 46 of the resonant cavity assembly.
A3, selecting and bonding the radio frequency antenna 30 to the pressure sensitive adhesive layer 12, so that the radio frequency antenna is connected and coupled with the radio frequency resonant cavity assembly 20.
And selecting antennas with different processes, such as a PET aluminum foil composite film chemical etching antenna, a PET aluminum foil die cutting antenna, an aluminum foil die cutting antenna and a copper wire antenna.
The feeding device of the radio frequency antenna 30 is used for pasting the antenna coupling end 31 of the radio frequency antenna 30 on the appointed position of the pressure sensitive adhesive layer 12, aligning and laminating the antenna coupling end 31 and the position of the aluminum foil 222 of the radio frequency resonant cavity coupling end of the pasted radio frequency resonant cavity assembly 20 on the pressure sensitive adhesive layer 12 into a whole, and even if the direct current resistance between the aluminum foil 222 of the radio frequency resonant cavity coupling end and the antenna coupling end 31 is large or insulated, the radio frequency coupling is not influenced to become a radio frequency tag.
If the radio frequency label with the release liner is manufactured, the method further comprises the step of compounding the release liner on the surface of the pressure-sensitive adhesive layer 12.
A4, slitting and rolling to form the radio frequency tag with the chip capable of being recycled and reused.
As shown in fig. 6, 7 and 8, and referring to fig. 1a to 5, the present invention provides a method for recycling rf tags, which is used for tearing off and recycling rf resonant cavity assembly peeling window 13 and rf resonant cavity assembly 20 in rf tags already adhered on package 1, and can strip off and recycle rf resonant cavity assembly 20 from the edge of rf tag or strip off and recycle rf resonant cavity assembly 20 from the middle of rf tag.
The principle of recycling the radio frequency chip 23 is as follows: the radio frequency resonant cavity assembly 20 is a combination of a radio frequency chip and a radio frequency resonant coil aluminum foil, the radio frequency chip is sealed on the aluminum foil through conductive adhesive, and the purpose of recycling the radio frequency chip is achieved through recycling the radio frequency resonant cavity assembly 20.
Anti-sticking coatings are arranged on two sides of the radio frequency resonant cavity assembly 20, so that the anti-sticking coatings are conveniently separated from the pressure-sensitive adhesive layer 12 and the radio frequency antenna 30 for recycling; in addition, the radio frequency resonant cavity assembly 20 is coupled with the radio frequency antenna 30, the mutual position error is within +1.5mm, the performance of the coupled radio frequency tag is not affected, the radio frequency resonant cavity assembly 20 is convenient to manufacture the radio frequency tag for multiple times, and the production efficiency is improved. The recovered radio frequency chip is reused, the process that the chip is reversely packaged on the radio frequency antenna 30 by using conductive adhesive for manufacturing each radio frequency tag is omitted, and the manufacturing cost of the radio frequency tag is saved.
In the present invention, the chip protection layer 24 of the rf resonant cavity assembly 20 prevents damage to the rf chip during recycling, ensuring that the recycling life is not less than 50 times.
In addition, the release coating has a lower affinity for the pressure-sensitive adhesive layer 12 than the pressure-sensitive adhesive layer 12 for the label paper, ensuring that no pressure-sensitive adhesive remains on the rf cavity assembly 20 when the rf cavity assembly 20 is peeled from the pressure-sensitive adhesive layer 12. The radio frequency resonant cavity assembly 20 is taken down from the package of the express mail by uncovering the radio frequency resonant cavity assembly stripping window 13, and then the radio frequency resonant cavity assembly 20 is smoothly stripped from the radio frequency resonant cavity assembly stripping window 13 by depending on the anti-sticking coating (the affinity of the anti-sticking coating and the packaging box paper is smaller than that of the pressure-sensitive adhesive layer 12 and the packaging box paper) on the radio frequency resonant cavity, so that the radio frequency resonant cavity assembly 20 is convenient to recycle.
The method for recycling the radio frequency tag with the chip capable of being recycled and used repeatedly comprises the following steps:
b1, stripping and recycling the stripping window part 13 of the radio frequency resonant cavity assembly on the label surface paper 10 on the surface of the express package, so that the radio frequency resonant cavity assembly 20 is separated from the radio frequency label which can be recycled and reused.
B2, separating the radio frequency resonant cavity assembly 20 from the peeling window part 13 of the radio frequency resonant cavity assembly.
B3, screening and arranging through a vibration screening disc to obtain the ordered radio frequency resonant cavity assembly 20.
Because the recovered rf resonant cavity assemblies 20 are stacked together in an unordered manner, they cannot enter the rf resonant cavity assembly slot assembly 40, cannot be applied for a second time, and need to be arranged by directional screening. If the arrangement is manually identified, the high cost makes the chip recovery impossible to popularize and apply, and the automatic arrangement screening is necessary. In the automatic arrangement screening, transverse screening arrangement is firstly carried out, then high-low direction screening arrangement is carried out, and finally front-back direction screening arrangement is carried out.
(1) Transverse screening arrangement
The radio frequency resonant cavity assembly 20 has a width different from a height, a width smaller than the height, and is arranged on a vibration screening disc 1 with the width as a standard, and resonant cavity assemblies with vertical arrangement higher than the vertical arrangement are screened out.
(2) High-low direction screening arrangement
On the vibration screening disc No. 2, a central position protruding guide rib 43 corresponding to the central notch position 25 is arranged at the central part of the space 46 of the resonant cavity assembly, the central notch position 25 of the radio frequency resonant cavity assembly 20 falls on the central position protruding guide rib 43, and the radio frequency resonant cavity assembly 20 with the compliance arranged in the height direction falls at the bottom of the space 46 of the resonant cavity assembly. The resonant cavity assembly with the reverse height direction arrangement is jacked up by the central protruding guide rib 43 of the space 46 of the resonant cavity assembly and is higher than the resonant cavity assembly with the compliance, so that the resonant cavity assembly with the reverse height arrangement and the compliance arrangement are divided into two rows.
(3) Front-rear direction screening arrangement
The bottom of the space 46 of the resonant cavity assembly on the No. 3 screening disc is provided with an off-center convex guide rib 44 which is off-center and corresponds to the edge notch 26 of the radio frequency resonant cavity assembly 20 in a compliance arrangement, so that the guide rib falls on the bottom of the space 46 of the resonant cavity assembly, and the radio frequency chip of the radio frequency resonant cavity assembly 20 is ensured to face forward.
Non-compliance arranged resonator assemblies with edge notch positions 26 of the radio frequency resonator assembly 20 and convex guide ribs of the resonator assembly space 46 not in one direction are jacked up by the off-center convex guide ribs 44, and the top surface is higher than the resonator assemblies with non-compliance in the front-back direction, so that the resonator assemblies are divided into two rows.
(4) The radio frequency resonant cavity assembly 20 with four arrangements is obtained through three screening arrangements, and the radio frequency performance detection is carried out.
And B4, screening to obtain a qualified radio frequency resonant cavity assembly 20 after radio frequency performance test, and loading the qualified radio frequency resonant cavity assembly into a radio frequency resonant cavity assembly clamping groove assembly 40 for standby.
When the single radio frequency resonant cavity assembly 20 is output by the resonant cavity assembly space 46, the single Zhang Shepin resonant cavity assembly 20 output by the resonant cavity assembly space 46 can not generate air-tight adhesion with the last single radio frequency resonant cavity assembly 20 because of the vent 27, and can not drive the last single radio frequency resonant cavity assembly 20 to go out of the clamping groove by mistake.
The chip can be recycled and the recycling application cost of the radio frequency tag can be used repeatedly:
the cost of the radio frequency chip is A, the cost of the radio frequency resonant cavity assembly is 0.1A after the radio frequency chip is removed, and the cost of the radio frequency chip packaged on the resonant cavity is 0.3A. Then: the cost of the chip resonant cavity assembly is 1.4A, and the chip resonant cavity assembly is recycled and reused for 50 times.
The cost of each application is 1.4A/50=0.028A, if the chip is 0.12 yuan, 0.12×1.4/50= 0.0033,0.168/50=0.0036 yuan, and the cost of each application is less than 4 centipoises of the RMB.
The radio frequency tag and the manufacturing and recycling method can be applied to the industries of express delivery, logistics, aviation, transportation and storage, and can also be applied to radio frequency tags (clothing tags, commodity tags and the like) in the commercial field. For example, in the express industry, the recovery process of the radio frequency tag includes:
s1, when a courier confirms that a receiver delivers a express mail, peeling off a radio frequency resonant cavity assembly peeling window part 13 from an express mail package along a tooth-shaped dental floss 131, collecting the peeled window part, and then delivering the express mail to the receiver;
s2, delivering the recovered radio frequency resonant cavity assembly stripping window part 13 to an express company by an express delivery person;
s3, the express company intensively delivers the recovered radio frequency resonant cavity assembly stripping window part 13 to a label manufacturer;
s4, separating the emergent frequency resonant cavity assembly from the peeling window part 13 of the radio frequency resonant cavity assembly by a label manufacturer;
s5, regularly placing the radio frequency resonant cavity assembly, and regularly placing the radio frequency resonant cavity assembly into a resonant cavity assembly space 46 of the radio frequency resonant cavity assembly clamping groove assembly 40 through a three-time vibration screening disc and radio frequency performance detection screening.
S6, mounting the radio frequency resonant cavity assembly clamping groove assembly 40 on a label production line to manufacture a new coupling type radio frequency label.
The invention is applied to the recovery process of the radio frequency tag, and has the following contributions to the application of the radio frequency technology in the industry:
1. greatly reduces the application cost of the radio frequency tag
The radio frequency tag of the express logistics is less than the traditional barcode tag in cost of money for one RMB, even if the cost of recycling the radio frequency resonant cavity assembly (such as recycling rewards delivered to express delivery personnel and the like) is added, the cost of detecting and sorting the performance of the radio frequency resonant cavity assembly into a clamping groove and secondary packaging can be controlled within 0.06 yuan, the application cost of the express radio frequency tag is ensured to be lower than 0.1 RMB, the efficiency of the express operation is improved due to the adoption of radio frequency technology, and the comprehensive benefit of reducing labor cost is greater than 0.1 RMB.
The invention solves the cost threshold of the application of the radio frequency technology in the express logistics industry.
2. Radio frequency chip application beneficial to pushing information memory
The large information memory radio frequency chip can write the codes of the express, the classification of the express and the codes of the express circulation nodes (sending out city, middle point and arrival city codes, more importantly, the last express delivery address codes) and automatically sort the codes into the corresponding delivery person boxes, thereby solving the requirement of automatic sorting of the last kilometer of express. Because of the high cost of the large information memory radio frequency chip, the large information memory radio frequency chip is not likely to be accepted by the express industry.
The invention solves the problem of high cost of the large information memory chip: the price of the large information memory chip is 80% higher than that of a common chip, and is 0.12 multiplied by 1.8=0.216 yuan, the price of the radio frequency resonant cavity assembly is 1.4A=1.4 multiplied by 0.216=0.302 yuan, the large information memory chip is recycled for 50 times, the use cost is 0.302 multiplied by 50=0.006 yuan each time, and the RMB is 6 centi.
The radio frequency resonant cavity assembly capable of being recycled for multiple times facilitates popularization and application of the large information memory chip, facilitates upgrading of application of the Internet of things from background data processing to foreground recognition processing, and improves efficiency of express delivery, logistics and aviation.
3. Economic benefit of coupling type radio frequency tag capable of recycling chips for multiple use
Taking 1000 hundred million express labels as an example:
(1) The chip is used 50 times
The annual actual consumption of the chip is 20 hundred million, the chip application cost is reduced by 98 percent, and the 98 hundred million RMB is saved by 0.1 yuan per chip.
(2) The packaging cost of the chip is reduced by 98 percent

(3) The express mail radio frequency tag can be recycled for multiple times due to the chip, the express delivery industry is promoted to be updated to radio frequency information operation from bar code information, hundreds of thousands of people of manual identification and manual sorting staff are reduced, the operation efficiency is improved, and the express delivery service quality is promoted.
