Problems solved by technology

However, further studies have shown that the above-mentioned existing dispensing technology still has the following defects or deficiencies: First, in the operation process, only the dispensing position is often controlled, and the state of the glue drop, especially the glue drop after curing, is not controlled. The detection and feedback of shape and size, and in fact, the shape and size of glue droplets are equ

Abstract

The invention discloses a dispensing control system for the production of an RFID (radio frequency identification) tag. The system comprises an XYZ tri-axis movement unit, a needle cylinder unit, an image acquisition unit, a system control unit and an air course regulation unit, wherein key process parameters such as dispensing pressure and dispensing time can be controlled, and meanwhile, a dispensing position and the final shape and size of an adhesive drop can be regulated to meet process requirements by detecting the dispensing position before and after dispensing, the shape and size of the adhesive drop before and after curing, pressure and temperature in a needle cylinder, a dispensing height and the like and correspondingly executing closed loop control processing. According to the system, quality can be rapidly, accurately and comprehensively controlled in the whole packaging process of the RFID tag; in addition, the system has the characteristics of compact structure, convenience for control, high adaptability and the like so as to be suitable for high-quality production processes of various RFID tags.

Description

technical field [0001] The invention belongs to the technical field of RFID tag encapsulation, and more specifically relates to a dispensing control system for RFID tag production. Background technique [0002] Radio Frequency Identification (RFID) is a non-contact automatic identification technology. Because RFID tags have waterproof and antimagnetic properties that barcodes do not have, and have the advantages of large storage capacity, long service life, strong anti-interference ability, long use distance, and high degree of intelligence, they are widely used in logistics, commodity tracking, manufacturing process control, and supply. Chain management, retail systems and automatic payment systems and other fields have broad application prospects. [0003] RFID tags are mainly composed of tag antennas and tag chip packages. As one of the core technologies in the tag electronic packaging process, dispensing technology is widely used in the packaging process of RFID tags. ...
