Problems solved by technology

Neither the tag antenna nor the tag chip technology of traditional tags can meet the repeated kneading and folding of clothes during washing. Most of them are due to the failure of the connection between the chip and the antenna or the damage and failure of the tag antenna. These two situations have become important factors affecting the application of tags.
In particular, there are very few studies on the characteristics and damage mechanism of the tag antenna, and because of the lack of research on the mechanism, the current solutions for this type of water-washing tags are not ideal
First of all, it cannot guarantee that the label will not be damaged or its performance will not change during application; secondly, it cannot guarantee the consistency of the initial state performance parameters of the label, and it is difficult to meet the reading requirements of intensive label groups for laundry management; in addition, the technology and production of the currently known solution products High cost, which limits the popularity of applications

Embodiment 1

[0033] see figure 1 , figure 2 , a UHF RFID tag for laundry management, including a tag chip 1, a tag antenna 3, a substrate 2 and a cover layer 3 for supporting and packaging the tag chip 1 and the tag antenna 2, and the tag chip 1 is placed on the tag antenna 3 The inductance loop is mutually coupled with the tag antenna 3, and the inductance loop is arranged in the middle of the tag antenna 3, and is a complete loop structure, that is, the current is a complete closed loop current.

[0034] The tag antenna 2 in this embodiment is a multi-strand conductive fiber twisted wire structure. The tag antenna 2 is formed by stranding a plurality of ultrafine conductive metal fibers, so that it has strong flexibility. The conductive metal fiber is composed of more than 10 strands of thin fibers, its resistivity is lower than 100 ohm / m, and its tensile strength is greater than 10 Newton. The electrical conductivity of the conductive fiber material is not lower than 10,000,000 Siem...

Embodiment 2

[0043] The manufacturing method of the UHF RFID label that is used for laundry management described in embodiment one, its specific steps:

[0044] (1) prepare substrate 2;

[0045] (2) The tag antenna 3 is embedded on the substrate 2 by ultrasonic wire planting equipment, and the middle of the tag antenna 3 is an inductive loop with a complete ring structure;

[0046] (3) Place the label chip 1 in the middle of the inductance loop by using an automatic chip suction machine;

[0047] (4) Covering the substrate with the cover layer 4 to wrap the tag antenna and the tag chip therein.

[0048] In the label making process of this embodiment, ultrasonic automatic wire planting equipment is used to weld the conductive fiber on the base of the chemical fiber fabric according to the design pattern, and an automatic chip suction machine is used to place the integrated package label chip in the middle of the label antenna ring, and then cover it with rubber or fabric And other flexibl...

Abstract

A UHF RFID label used for laundry management comprises a label chip, a label antenna, and a substrate and a covering layer which are used for supporting and packaging the label chip and the label antenna. The label antenna is a multi-strand conductive-fiber stranded wire structure. The label chip is placed in an inductance loop of the label antenna and is mutually coupled and connected to the label antenna. The label possesses characteristics that safety and reliability are achieved; cost is low; an environment adaptability is good; and kneading resistance, extrusion resistance and high speed impact resistance capabilities are high.

Description

technical field [0001] The invention relates to a UHF RFID tag, in particular to a UHF RFID tag used for laundry management and a manufacturing method thereof. Background technique [0002] RFID technology is developing rapidly, its application fields are becoming wider and wider, and the structure of products is also diverse. The usual UHF electronic tag, which uses non-contact automatic identification technology, its basic principle is to use the antenna on the electronic tag to receive the electromagnetic wave signal from the reader and the sending tag itself, when the reader scans the UHF electronic tag , to realize the automatic identification of tagged objects. UHF electronic tags are generally composed of a tag antenna and a tag-specific chip. The function of the tag antenna is to send and receive electromagnetic wave signals. Its performance is directly related to the stability and sensitivity of the sending and receiving signals (effective operating distance); the ...
