A kind of manufacturing method of normal mode spiral dipole electronic tag yarn

Abstract

The invention discloses a manufacturing method of a normal-mode spiral dipole electronic label yarn: printing a pair of rectangular conductive bridge islands with a fixed spacing on a flexible narrow tape to form a bridge assembly; and on the rectangular conductive bridge islands of the bridge assembly The RFID tag chip is assembled point-to-point; a pair of conductive fibers of a certain length are symmetrically fixed to the rectangular conductive bridge island of the bridge assembly with anisotropic conductive glue; the conductive fiber and the RFID tag and the rectangular conductive bridge island are coated and packaged with flexible insulating glue The assembly point is to form a yarn-shaped linear dipole label middle piece; the yarn-shaped linear dipole label middle piece is wrapped on a non-conductive bearing yarn with a certain degree of wrapping, and two non-conductive yarns are outsourced to each other, forming a method Toward the mode spiral dipole electronic tag yarn. The preparation method of the invention is simple, the technological process is short, the existing technical problems are overcome, the production cost is reduced, and the standardization and process-based industrial production requirements are met.

Description

technical field [0001] The invention relates to a manufacturing method of a normal-mode spiral dipole electronic tag yarn, in particular to a continuous manufacturing method of a normal-mode spiral dipole electronic tag yarn, which belongs to the technical field of RFID tag yarns. Background technique [0002] Compared with traditional information labels such as barcodes and two-dimensional codes, RFID tags have the advantages of strong environmental adaptability and multiple simultaneous reading. In order to realize the intelligent management of textiles, improve the timeliness and accuracy of informatization, and reduce labor costs, RFID tags are in great demand in the warehouse logistics management of textiles and clothing anti-counterfeiting. The labels currently applied to fabrics are mainly large-area two-dimensional fabric-based RFID labels such as embroidered labels and screen-printed labels. Although such labels have the advantages of wearability and washing resista...

Problems solved by technology

If the FLIP CHIP type RFID tag chip is used, the requirements for packaging equipment are high, the packaging is difficult, and the packaging success rate is low; if the SMD type RFID tag chip is used, the conductive yarn / fiber is wound on the lead angle of the RFID tag chip, and the RFID The label production capacity is low, which is not conducive to the process industrial production of label yarn

At the same time, the cost of SMD-type RFID tag chips is relatively high compared to the profits of the textile industry, which is not conducive to the commercialization of RFID tags.

[0004] Therefore, although the existing RFID tag yarn meets the requirements of invisible anti-theft, good softness, and little impact on wearing performance, the traditional automatic roll-to-roll binding process is not suitable for large-diameter flexible conductive fibers and small-sized chip contact pads. In the preparation process, because the connection and packaging between the RFID tag chip and the conductive fiber is difficult, the existing research samples often use the packaged chip to start manual sample preparation, and the RFID tag yarn preparation process is complicated, the production efficiency is low, and it is not compatible. A series of problems such as the yarn production process, the roll-to-roll automatic production process technology that meets the requirements of the normal mode spiral dipole RFID tag yarn has not yet been established
