[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] An RFID coating method for tires includes the following steps: providing two rubber sheets 2 made of the same material as the tire's airtight layer; wrapping an RFID tag between the two rubber sheets 2; rolling the RFID tag and the two rubber sheets 2 to expel the gas between them to form a tag assembly; and storing the tag assembly under cold storage. Cold storage helps maintain the freshness of the rubber sheets, prevents them from hardening, and facilitates vulcanization bonding.

[0027] In this embodiment, the rubber sheet 2 is circular in shape. The thickness of the rubber sheet 2 is 0.45 mm to 1.2 mm, and the diameter of the rubber sheet 2 is 15 mm to 25 mm. The RFID tag is wrapped between two rubber sheets 2, with the RFID tag located in the middle of each rubber sheet 2, and the edges of the two rubber sheets 2 overlapping.

[0028] In this embodiment, the refrigerated storage temperature is between 0 degrees Celsius and 20 degrees Celsius.

[0029] The RFID tag includes a fiberglass cloth 3, an RFID chip 1, and an epoxy resin layer 4; the RFID chip 1 is disposed between the fiberglass cloth 3 and the epoxy resin layer 4, and the fiberglass cloth 3 and the epoxy resin layer 4 make it easier for the chip to fuse with the rubber vulcanization.

[0030] When the RFID tag is wrapped between the two rubber sheets 2, it is vented by a rolling device. The rolling device includes a rolling roller 5 and a pressure regulating system 6. The rolling roller 5 rolls the RFID tag and the two rubber sheets 2, and the pressure regulating system 6 controls the rolling pressure of the rolling roller. During the rolling process, the RFID tag is wrapped between the two rubber sheets 2 and placed on a worktable. After the two rubber sheets 2 are combined with the RFID chip 1, they pass through the rolling roller 5 via a conveyor belt on the worktable to achieve venting.

[0031] This invention also provides a method for manufacturing a tire, including the refrigerated label assembly. The method includes the following steps: in the green tire blank forming process, a green tire blank semi-finished product or green embryo is placed flat on a workbench; the label assembly is implanted into the surface of the airtight layer of the green tire blank semi-finished product or green embryo; and the label assembly is fused with the airtight layer through vulcanization. During the tire blank preparation process in the forming process, the label assembly is directly implanted onto the surface of the airtight layer without the use of adhesives or additional adhesive films, and without the need for punctures; the label assembly is fused with the tire airtight layer through vulcanization.

[0032] The present invention also provides a tire, the tire including an airtight layer, the surface of which is provided with an RFID tag; wherein the RFID tag is wrapped between two rubber sheets 2, the rubber sheets 2 being made of the same material as the airtight layer of the tire; the RFID tag and the two rubber sheets 2 are rolled together and the gas between the RFID tag and the two rubber sheets 2 is expelled to form a tag assembly; after refrigeration, one side of the tag assembly abuts against the airtight layer and is cross-linked together by vulcanization.

[0033] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
