Abstract

The invention discloses a method for making an electromagnetic label, comprising the following steps: slicing and transferring resonant diaphragms into a bottom box, wherein the bottom box is internally provided with a plurality of dividable cavities and each cavity adsorbs two resonant diaphragms; slicing magnetic biasing diaphragms, carrying out heat treatment on the magnetic biasing diaphragms, testing the br value as 1.4T and then adhering the magnetic biasing diaphragms on a thin oil film, wherein the magnetic biasing diaphragms on the thin oil film are in one-to-one correspondence to the cavities on the bottom box; hot-melting the thin film with the magnetic biasing diaphragms and a bottom shell into a whole so that two resonant diaphragms and one magnetic biasing diaphragm are orderly superposed in each cavity of the bottom box; and magnetizing for 20-30sec, detecting whether an alarm is given and dividing the qualified finished bottom box into monomer labels, wherein the monomer labels respectively comprise one cavity of the bottom box as well as two resonant diaphragms and one magnetic biasing diaphragm in the cavity. In the invention, the magnetic biasing diaphragms and the resonant diaphragms can be combined into electronic labels by utilizing an acousto-magnetic principle; and the method disclosed by the invention has the advantages of being simple in process, low in cost, convenient for processing, stable in resonant frequency and the like.

Description

technical field [0001] The invention discloses a method for manufacturing an electronic magnetic label, belongs to the technical field of electronic magnetic label manufacturing according to the International Patent Classification (IPC), and in particular relates to a method for making a magnetic label suitable for marking products in retail supermarkets and other places. Background technique [0002] The electronic article anti-theft (theft) system, referred to as the EAS system, is one of the commodity security measures widely used in the large retail industry. EAS system is mainly composed of three parts: detector (Sensor), decoder (Deactivator) and electronic label (Electronic Label and Tag). Electronic tags are divided into electromagnetic type, radio frequency type, magnetic-mechanical type, etc., and an existing acoustomagnetic anti-theft tag (see US Pat. From top to bottom, it is composed of cover film, double-sided adhesive tape, bias sheet of semi-hard magnetic ma...
