Long-distance radio frequency electronic identification structure for tires

Abstract

The invention discloses a long-distance radio frequency electronic identification structure for tires. When a tire is manufactured and identified by an electronic tag reading device, an ultrahigh frequency electronic tag is arranged on a main carcass of the tire, a radio frequency identification RFID chip receives and feeds back through electromagnetic wave signals generated by a far-field copperfilm antenna and the electronic tag reading device end, the frequency band and the bandwidth of the electromagnetic wave signals are adjusted by a frequency band / bandwidth adjusting portion, the fieldtype effects when a bead steel wire and a steel wire ring layer reflect the electromagnetic wave signals are adjusted through first and second field effect adjusting grooves of first and second fieldeffect adjusting portions, so that the electronic tag reading device can read an ID identifier of the ultrahigh frequency electronic tag on the main carcass at a wide angle for a long distance, thenthe tire individuals can be accurately identified by using the ID identifiers in the transportation, detection, stack storage and factory leaving processes after the tires are manufactured, so as to facilitate the tire production management and realize a low error rate.

Description

technical field [0001] The invention relates to a long-distance wireless device which can use ID identifiers to identify tires in the process of transportation, detection, stacking, storage, and delivery after the tires are manufactured, and has the advantages of convenient tire production, convenient management, and low identification error rate. Radio frequency electronic identification of tire structure. Background technique [0002] The production process of tires includes mixing of rubber raw materials, strip calendering of mixed rubber materials, secondary process of forming raw tires and vulcanization of raw tires to complete the final shape of tires, tread patterns and sidewall marks. After the tires are manufactured, they must be transported or sent to the inspection room based on the consideration of safety in use. After passing strict quality inspections, the qualified tires are sent to the warehouse for storage, and the product serial number is recorded at the ti...

Problems solved by technology

After the tires are manufactured, they must be transported or sent to the inspection room based on the consideration of safety in use. After passing strict quality inspections, the qualified tires are sent to the warehouse for storage, and the product serial number is recorded at the time of delivery; from the inspection to the delivery process, Traditionally, human stickers are mostly used for identification, which is labor-intensive and prone to mistakes; in the existing one-dimensional or two-dimensional barcode label identification methods, the use of optical scanners for electronic identification can reduce errors, but manual or mechanical automatic scanning is still necessary. There is a limitation of scanning distance or angle, which leads to the situation that it cannot be completed or recognized. In order to meet the needs of the production line with high recognition accuracy and low error rate, it is necessary to improve the existing recognition method
