Care label-based UHF RFID tag based on screen printing

Abstract

The present invention relates to a care label-based UHF RFID tag based on screen printing. A manufacturing method of the care label-based UHF RFID tag based on screen printing comprises the steps of: selecting a care label as a substrate for printing an antenna; then printing electrically conductive printing ink on the substrate to form an antenna through a screen printing method; after drying, bonding a connecting band of a UHF RFID tag chip to the antenna by a conductivity type binder; and finally performing coating protection for the chip, wherein a coating material adopts flexible resin. Compared with the prior art, the care label-based UHF RFID tag of the present invention has the beneficial effects that: the flexibility of the care label is retained by the care label-based UHF RFID tag; the care label-based UHF RFID tag is perfectly fit with clothes; the UHF RFID antenna is endowed with a certain flexibility, and can bear certain bending or deformation; the care label-based UHF RFID tag is simple in structure and convenient in manufacture; the care label-based UHF RFID tag is printed by a screen printing machine, can achieve mass production, and is suitable for popularization.

Description

technical field [0001] The invention relates to a technology for printing a wearable and washable UHF frequency band RFID tag using a flexible water-washable label textile material as a substrate, and belongs to the technical field of combining radio frequency identification with textile and clothing. In the logistics, management and anti-counterfeiting of textile and clothing. Background technique [0002] RFID (Radio Frequency Identification), as a highly intelligent and advanced Internet of Things technology in the 21st century, has penetrated into human daily life and gradually developed. A complete and working RFID system includes at least two parts: electronic tags and reading devices. The electronic tag is an ultra-thin integrated circuit tag composed of coupling elements and chips, and its core components are the chip and the antenna responsible for sending and receiving signals. Compared with traditional information tags, such as barcodes and QR codes, RFID tags h...

AI Technical Summary

Problems solved by technology

This kind of clothing internal label also has the problem of the label described in the aforementioned patent, which affects the wearing comfort

In addition, the reading performance of the label is affected by the difference in the dielectric properties of the marked clothing material. The labels stated in the above patents do not give a specific solution, and how to protect the label of the clothing after mechanical forces such as washing are still good. There are also certain defects in maintaining the original reading effect, which requires a reasonable design of the water-washed UHF RFID tag
