Problems solved by technology

[0006] Even if there is no direct damage to the RFID Chip, the stress generated by the use environment may disconnect the RFID Chip and the antenna, or cause poor recognition of the antenna circuit.
In addition, the deformation of the antenna and the change of the operating frequency in the high temperature and humid environment will also lead to the problem that the reading [Reading] distance becomes smaller.
Moreover, it is very fragile under moisture and humidity, and the reading [Reading] distance may become smaller and poor recognition may occur.

Embodiment Construction

[0029] In the following, the practical application of the present invention will be illustrated in detail with reference to the accompanying drawings.

[0030]The antenna radiation part 10 and the power supply part 20 are designed separately in order to improve the internal structure of the RFID tag in view of the extremely harsh use environment. Connect to the connection with the antenna radiation part 10 at the lower part with a conductive through-hole 30 . At the same time, the antenna radiating part 10 and the power supply part 20 can also be connected by means of electromagnetic coupling [Electromagnetic Coupling]. The antenna radiation part 10 and the power supply part 20 are thermocompression welded during the packaging [Packaging] process. An RFID Chip40 is bound on the upper part of the power supply part 20. The power supply part 20 is made of a hard material that is not easily deformed. When washing, the RFID Chip40 will not be affected by the stress caused by any d...

Abstract

The invention relates to a RFID (Radio Frequency Identification Devices) tag with UHF (Ultra High Frequency) bandwidth special for washing and still durable in use at an extreme severe using environment and a designing and manufacturing method thereof. The antenna emitting part and a power supply part of the RFID tag are designed into a separated type; the power supply part is made of hard materials which are difficult to deform so as to ensure that an RFID IC (Integrate Circuit) chip and the power supply part are safe from damage under external environmental stress; the antenna emitting part and the power supply part are hermetically connected through thermal compression welding in the packaging process; and the power supply part is in direct circuit connection with the antenna emitting part through a conductive through hole, or the power supply part is indirectly connected with the antenna emitting part in an electromagnetic coupling way. The RFID tag is used for being arranged on clothes and has the advantages of chemical resistance, water tightness, heat resistance and good durability at a severe washing environment.

Description

technical field [0001] The invention relates to a durable RFID [Radio Frequency Identification] washing label and a design and manufacture method thereof which are still durable under extremely harsh use environments. Specifically, it is a special label that is attached to clothing, and after washing or high-speed dehydration and high-temperature ironing, the RFID Chip and the label remain intact and maintain their original performance. Background technique [0002] Generally speaking, RFID [Radio Frequency Identification] technology refers to a technology that uses radio waves to identify long-distance information. The RFID tag consists of an antenna and a direct circuit, the information is recorded in the direct circuit, and the information is transmitted to the reader through the antenna. This information is used to identify the status of the tag request. Simply put, it has similar functions to barcode [Barcode]. [0003] The difference between RFID and the bar code [B...
