With the progress and development of society, the European Union, the United States, Japan, South Korea and other countries and regions have successively introduced tire labeling laws, requiring tires to be labeled to indicate the level of fuel efficiency, rolling resistance, rolling noise, and grip on wet roads. . my country's tire labeling system is also in the process of vigorously advancing. At present, tire traceability marks on the market generally use the form of "barcode + sidewall information" to store various types of tire information, but the barcode and sidewall position information are located on the surface of the carcass, and tires will wear off soon after use . Once the information cannot be seen visually, it means that the tire information is lost, so that information such as tire model, pattern, and diameter cannot be identified. If tires are illegal and unsafe for use (unqualified tires, overloaded use, expired use, etc.), it will directly cause difficulties for the user's use, maintenance, and settlement of claims, leading to disputes, and even frequent safety accidents. Waste of energy resources and damage to the environment. The application of RFID technology can regulate the orderly production and sales of the tire industry (prevent counterfeiting, OEM, and cross-country goods), and realize the full life cycle management of tires; regulate the transportation industry to ensure personal and property safety; promote and standardize the tire retreading industry to achieve tires Circular Economy.
Radio frequency identification RFID application demonstration in tires: In the tire building process, the electronic tag is implanted inside the tire, which can withstand the deformation, high temperature and high pressure in the tire building and curing process. The finished tire has undergone X-ray inspection, bubble inspection, dynamic balance and uniformity inspection, durability test inspection, etc., showing its reliable performance. Implanting RFID electronic tags into the tires, from a safety perspective, mainly includes the combination of electronic tags and tire rubber, that is, the electronic tags must be integrated with the tire after being implanted into the tire, and no bubbles and delamination will affect the quality of the tire; The weight of the electronic tag cannot affect the quality of the tire dynamic balance, that is, the volume and weight of the electronic tag after packaging must meet the requirements of dynamic balance and uniformity of the tire; from the aspect of the reliability of the tag, the electronic tag implanted in the tire has to bear The stretching, high temperature, high pressure, and flexural deformation during tire production and use are used throughout the tire's life cycle; from the perspective of reading distance, the reading distance of the electronic tag implanted in the tire must meet the needs of later tire use management. It can be seen that the combination of RFID technology and tire manufacturing technology can not only solve the problems encountered in the current tire identification and traceability processes, but also that the tires use RFID electronic tags embedded in the tires, which can write tire production data, sales data, and use Data, retreading data, etc., and the corresponding data can be collected and read through the terminal at any time, and combined with the corresponding management software, the recording and traceability of the tire's full life cycle data can be realized.
