A kind of manufacturing method of punching aluminum foil rfid radio frequency antenna

Abstract

A method for manufacturing an RFID radio frequency antenna by punching an aluminum foil. A complex RFID radio frequency antenna pattern is decomposed into two or three groups of simple segment patterns, then two or three groups of punching dies are manufactured according to the two or three groups of segment patterns, aluminum foil segments punched respectively are connected to one another in a lapped mode, the lap joint parts of the aluminum foil segments are welded using ultrasonic waves or treated using an acupuncture process, and the two or three groups of punched aluminum foil segments are combined to form a complete radio frequency antenna. According to the method, an aluminum foil radio frequency antenna can be manufactured by punching on paper, films and rubber having different thicknesses, radio frequency products of different materials can be manufactured conveniently, the production process is simple, generation of waste water is avoided, and pollution to the environment is avoided; moreover, aluminum foil waste is easy to recover, efficiency is high, the manufacturing cost is low, and the aluminum foil radio frequency antenna is suitable for large-scale production.

Description

[0001] 【Technical field】 [0002] The invention relates to a method for manufacturing a die-cut aluminum foil RFID radio frequency antenna, and the invention belongs to the technical field of RFID radio frequency technology application. [0003] 【Background technique】 [0004] At present, the application of RFID radio frequency technology has developed rapidly from the initial electronic tags to RFID radio frequency packaging, covering logistics, manufacturing and other industries. Large-scale, large-scale production and use require RFID radio frequency antennas to be produced at low cost and without waste gas waste water, does not pollute the environment. At present, the types and defects of the RFID radio frequency antenna production process in the prior art are: [0005] 1. Chemical solvent etching aluminum foil method to make RFID radio frequency antenna: [0006] The raw material used in this method is PET aluminum foil, and its technological process is to paste photosen...

AI Technical Summary

Problems solved by technology

[0009] 3) The supporting base film of the aluminum foil antenna is PET film, which can adapt to the chemical solvent etching process, and the chemical etching process cannot make antennas on paper;

[0010] 4) When making paper RFID radio frequency tickets and radio frequency packaging, the PET base material is used to etch the antenna, which will definitely produce PET base material protrusions on the surface of the radio frequency ticket cards and radio frequency packaging, which will affect the smooth surface and affect the quality of color printing

[0013] 1) The production cost is high, because the conductive ink requires low resistance and good characteristics, the traditional carbon conductive ink cannot be used, and the price of gold or silver conductive ink is high, resulting in high production cost of printed radio frequency antenna;

[0014] 2) Printed RF antennas have poor folding resistance and short service life

[0017] 1) RF antennas that cannot make complex graphics: such as HF coil antennas;

[0018] 2) Because the antenna has a PET backing film or release paper, when making radio frequency tickets and radio frequency packaging, the thickness of the PET paper film (release backing paper) produces protrusions on the surface of the radio frequency tickets and radio frequency packaging, affecting the flatness and affecting Color printing quality

[0020] The raw material that this method uses is aluminum, PET film, and its technology is to prepare antenna pattern release agent on PET film, vacuum aluminizing then, then transfer release agent pattern aluminum film, finally make PET base material radio frequency antenna, its defect Yes: Because the aluminized film is very thin, which is a few tenths of the thickness of the chemically etched aluminum foil antenna, the conductive effect is poor, and increasing the thickness of the aluminum foil film will result in extremely high production costs, so it has not entered the market application
