Description

RFID tag for tires {RFID TAG FOR TIRE}

Various embodiments of the present invention relate to an RFID tag for a tire.

RFID tags store product information for product identification, and can be used for product management by attaching to the exterior of a product or a packaging box of a product.

In particular, since the RFID tag provides product information using a radio frequency, it has a wider recognition range and easier recognition than a barcode label that requires an optical reader.

In general, the RFID tag may include a base board, a base film to which an antenna and a chip are attached, and a cover film protecting the base film. Here, the cover film may be attached to the base film through an adhesive, and the base film may be attached to the exterior of the product or the packaging box of the product.

The RFID tag attached to such a tire is attached to the inner surface of the tire adjacent to the anti-deformation ring, and is used to manage only from the time the tire is made to the factory. When the RFID tag is attached close to the deformation preventing ring made of metal, an error may occur in the recognition of the antenna, so it must be attached to the inner surface of the tire so as to be separated from the deformation preventing ring. However, as the distance from the anti-deformation ring to the RFID tag increases, when the tire is mounted on the vehicle and travels, the chip may be damaged due to vibration of the road surface or a change in pressure inside the tire.

The present invention provides an RFID tag for a tire capable of preventing damage to an antenna pattern and an RFID chip from an external environment and at the same time preventing deterioration of the antenna performance, and a tire stretching action that may occur after a tire manufacturing process and shipment.

And a top cover layer formed to cover all of the first adhesive layer and the first adhesive layer.

The length of the connection area equal to the separation distance between the chip area and the antenna area may have a length of 20 mm to 50 mm.

The base film may be further formed to electrically connect between the antenna pattern and the RFID chip on one surface, and a connection pattern of a conductive metal integrally formed with the antenna pattern is positioned in the chip region and the connection region.

The antenna pattern and the connection pattern may be thermally compressed while being interposed between the base film and the antenna protective layer, and may be wrapped by the antenna protective layer.

The base film and the antenna protective layer are made of polyimide (PI), and the thickness of the base film may be thicker than that of the antenna protective layer.

The chip protection layer may be interposed between the RFID chip and the first adhesive layer, and between the antenna protection layer and the first adhesive layer in the chip area.

The chip protective layer may be made of polyether ether ketone (PEEK).

The top cover layer may be made of polyethylene terephthalate (PET).

It may further include a second adhesive formed to cover all the other surface of the base film.

The first adhesive layer may be made of a material that is softer than the top cover layer.

The antenna region may extend a predetermined length in the same direction as the extension direction of the antenna pattern, and the chip region may be spaced apart from the antenna region by a predetermined distance in a direction perpendicular to the extension direction of the antenna region.

The RFID tag for a tire according to the present invention can prevent damage to an antenna pattern, an RFID chip, and a connection pattern due to high temperature, high pressure, and stretching action of the tire generated during the tire manufacturing process.

In addition, the RFID tag for tires according to the present invention is mounted so that the RFID chip is adjacent to the deformation prevention ring to prevent damage to the RFID chip due to road vibration or air pressure change after the tire is shipped, and at the same time, the antenna pattern is in the tire deformation prevention ring. By being separated by a certain distance, it is possible to prevent an antenna recognition error.
