Description

An electronic label for RFID flexible laundry identification

technical field

The invention relates to a flexible RFID (non-contact identification) intelligent laundry electronic tag, which belongs to the field of non-contact identification electronic tags.

Background technique

In the laundry industry, in order to distinguish the type, method and attribution of laundry, the traditional method is to use a special laundry label paper, use different colors to distinguish clothes at different collection points, or different batches of clothes, and put them on the label Write different numbers on paper to distinguish clothes from different customers. The recycling rate of this kind of label paper is low, information identification and sorting are difficult, and the cost is high. Another method is to write the number on the cloth strip in combination with the number on the receipt receipt, and then sew the numbered cloth strip onto the clothing by hand. When the customer picks up the clothes, cut off the cloth strips and discard them, or tear off the label paper and discard them. It is difficult to reuse and cause waste, and each piece of clothing must be operated in this way. These two methods are not only very cumbersome, time-consuming and labor-intensive, but also very inefficient, and the identification content is not comprehensive and error-prone.

Due to the development of the laundry industry, there are about five types of laundry labels (6 washing signs, 7 dry cleaning signs, 4 rinsing signs, 8 drying signs, and 7 ironing signs), covering more than 30 laundry processing methods , plus personalized logo, its classification has far exceeded 100 kinds. Obviously, traditional marking methods are not conducive to the development of the laundry industry. In order to change the operation situation where laundry information is seriously lagging behind, the invention uses a non-contact identification (RFID) flexible laundry label electronic tag made by a special process, which overcomes the above-mentioned disadvantages and greatly improves work efficiency.

Contents of the invention

In order to overcome the disadvantages of the traditional laundry industry, such as cumbersome sorting operation, low efficiency, too small label capacity, and error-prone, the present invention adopts special packaging materials and manufacturing techniques, and adopts non-contact identification (RFID) technology to make non-contact identification (RFID) Electronic tags for flexible laundry identification, combined with RFID reading and writing equipment, make laundry identification and information tracking very accurate, and it is convenient and fast to use.

The technical solution adopted by the present invention to solve its technical problems is:

An electronic label for RFID flexible laundry identification, which is characterized in that it is composed of flexible silicone rubber, transparent glue, and a core material assembly. The flexible silicone rubber is composed of upper and lower layers. The component is arranged between two layers of flexible silicone rubber; the core material component is composed of RFID bare chip, tag antenna, bare chip bonding bump, anisotropic conductive adhesive, synthetic glue and PET insulating medium, and the bare chip bonding bump It is arranged on the circuit surface of the RFID bare chip, and the anisotropic conductive adhesive is laid between the tag antenna and the bonding bump of the bare chip.

The above-mentioned tag antenna is a double-layer aluminum film tag antenna using etching and circuit bridge connection technology. The PET insulating medium is arranged between the double-layer aluminum film tag antennas, and the tag antenna and the PET insulating medium are bonded with synthetic glue.

In the present invention, a layer of RFID core component (Inlay) composed of a tag antenna and an RFID bare chip is arranged in the middle of a flexible silicon rubber interlayer material. The Inlay can use any HF and UHF aluminum film etching antenna and RFID bare chips with different functions. Flip-chip formation, or an ultra-thin soft-packaged COB and aluminum film etched antenna. After the special glue is coated on both sides of the silicone rubber layer to bond the Inlay, it is made by hot pressing and punching. It can simultaneously read the data information of multiple electronic tags that identify clothing without contact (even through clothing layer barriers); especially the excellent anti-collision mechanism for reading multiple electronic tags can instantly realize the identification of multiple electronic tag terminal identifiers Reading can greatly improve the work efficiency of clothing management.

The invention sews the electronic tags for non-contact identification flexible laundry signs with detailed information on the clothes to be washed one by one, and sews them into the neckline of the clothes, and tracks and locates them through the reader-writer, not only can grasp the specific processing conditions of each piece of clothes , location and processing status, and additional information such as tracking the number of times of use and the replacement period can also be seen at a glance, thus making the management of the laundry industry more efficient and accurate.

The size of the electronic label for non-contact identification flexible laundry label of the present invention can be made into various shapes according to the requirements of use, such as square, rectangular, circular and other appearances. The thickness of the label can be controlled in the range of 0.4-1.2mm according to the needs. The electronic tag for flexible laundry identification can work normally at a high temperature of 120 degrees, and it will not cause damage to the electronic tag even if it is pressed with a steam iron. The buttonhole position enters the laundry treatment environment together with the clothing, and the button label is taken out after washing for recycling.

The beneficial effects of the present invention are: the electronic tag for non-contact identification flexible laundry label of the present invention has a simple structure, touch-free operation, convenient information management, and the terminal can even realize automatic sorting and corresponding operation processing; it is made of flexible materials and can be curled 360 degrees It does not affect normal use; all the processing information of clothes is digitized, which is convenient for intelligent sorting, query and management; it can be used repeatedly and the cost is low; UHF electronic tags can read multiple RFID tags in an instant, significantly improving work efficiency ;Waterproof, pressure-resistant, heat-resistant, acid-alkaline lotion-resistant and other characteristics, with high durability, suitable for complex and harsh working environments; different appearances, sizes and styles can be made according to actual needs. Using bare chip flip-package technology, it is applicable to any RFID bare chip and aluminum film etching antenna of HF and UHF frequency band specifications, making the electronic tag products for non-contact identification flexible laundry labels serialized.
