A substrate conveying control method for RFID tag production

Abstract

The invention discloses a substrate conveying control method used for RFID label production. The substrate conveying control method comprises the steps that a series of technological parameters related to substrate conveying are input, and then current state parameter values of substrates are collected and obtained; a plurality of current tension values of the substrates are compared with a reference value respectively and a dual tension control mode is adopted to guarantee the stability of the tension of the substrates; in addition, a deviation rectifying method based on machine vision is adopted to guarantee accurate transverse and longitudinal locating of the substrates. Through the substrate conveying control method used for RFID label production, the tension control requirements of the substrates can be better met, and the locating precision is further improved. Meanwhile, the substrate conveying control method has the advantages of being adapted to various complex working conditions, not prone to being disturbed, high in efficiency, high in reliability and the like.

Description

technical field [0001] The invention belongs to the field of RFID label manufacturing equipment, and more specifically relates to a substrate conveying control method for RFID label production. Background technique [0002] The basic principle of radio frequency identification (Radio Frequency Identification) RFID technology is to use electromagnetic wave coupling for communication to identify target objects and obtain target object information. Its most eye-catching application is as an electronic label, which has the advantages of waterproof, antimagnetic, high temperature resistance, long service life, large reading distance, and free change of stored information, etc. that barcodes do not have. [0003] The RFID label packaging equipment adopts the roll-to-roll conveying scheme to realize the transmission function of the substrate, and the substrate antenna sequentially passes through dispensing, flip-chip bonding, hot-press curing, online detection and other stations to...

Problems solved by technology

For example, CN200810048371.1 discloses an intermittent flexible substrate tension control device, in which the control of the substrate tension is realized through the synchronous control of the angular displacement of the active feed motor and the driven take-up and discharge motor; however, due to the The shaft system forms a closed loop and is only coupled through the tension sensor, which cannot eliminate the change in the tension of the substrate caused by the asynchronous position of the material rollers caused by various disturbances
