Rfid tags embedded in the tires can be located, so how to put rfid tags embedded in the tires? Does this approach make sense? Today we will study it! Radio frequency identification (RFID) technology is a kind of non-contact automatic identification technology which has emerged since the 1990s. It USES the transmission characteristics of radio frequency signal and space coupling or radar reflection to realize the automatic identification of the identified object. Compared with the traditional magnetic card, IC card, the biggest advantage of this technology lies in the distance separation and non-contact identification, so no manual intervention is needed to complete the identification work, which is suitable for realizing the automation of the system and is not easy to damage, can recognize high-speed moving objects, and operate quickly and easily. Aiming at the application of RFID technology in the tire industry, this paper focuses on the RFID RFID tag implantation process and the reliability detection after implantation. 1. Implantation method Efficient implantation method is a necessary condition for the application of RFID tags in the industrialization of tires. It is mainly introduced from the two aspects of the tire forming process and the surface of the tire billet. 1.1 implantation during tire molding RFID tags embedded in the tire can be completed in the process of tire forming, that is, the production process of tire blank. The implant USES film to attach an electronic tag to a semi-finished part of the tyre, which can be a belting layer, a cord layer, a tyre side adhesive or a lining layer. The film used for pasting must be consistent with the corresponding semi-finished component material. On the molding drum, after finishing the tire fabric, paste the electronic label on the fabric surface with the film. After the tire body is reversed, the electronic tag is sealed in the tire side. The implantation method of all-steel tire and semi-steel tire is basically the same. 1.2 surface implantation of embryo In addition to the implantation of electronic tags in the process of tire molding, it can also be implanted in the tire billets at the end of molding. This method is to use film to paste the electronic label on the surface of the tire, paste in the lining layer surface must use the lining layer film, paste in the outer tire side surface must use the tire side glue. Compared with the implantation in the molding process, this method can shorten the reading distance of the label. The reason is that the rubber close to the mold is more fluidity when the tire is vulcanized than the rubber inside, and the electronic label bears relatively large stress, which affects the signal transmission. 2 implantation position The tire is composed of a variety of semi-finished parts. The placement of electronic tag in the tire is very important for reading and writing the chip information after the tire is implanted. The placement of the implant should be conducive to the reliability of the electronic tag while minimizing its impact on tire quality. Therefore, the placement selection is a key problem for the application of RFID tags in tire quality control. It can meet the requirement of performance by the way between the tire side filler and the tire side filler. This method is completed in the process of caring and closing of the fetus. After stitching and pressing of the tire body cord, an electronic label is pasted at the position marked by the laser positioning cursor, and then the following process continues. 3. Reliability test of electronic tag packaging Through bubble detection, X-ray detection, dynamic balance uniformity detection and durability test, the tire implanted with RFID electronic tag is tested to verify the anti-folding pressure, anti-interference and high temperature resistance of the electronic tag and whether it will affect the tire performance. 3.1 bubble detection Generally speaking, if a foreign body is stored in the tire and used for a long time, the foreign body may be detached from the tire rubber, and the gap will gradually increase, eventually leading to the tire scrap. In this regard, we have done bubble detection on the RFID tires after mass production and road test. The results showed that no bubbles were found in the implanted RFID tags. Therefore, RFID electronic tags can be well combined with the tire, will not cause the internal tire bubbles. 3.2 X-ray detection The structure of the embedded RFID tags can be checked with the help of the tire X-ray detection equipment. Due to the tire manufacturing process to withstand high temperature and high pressure and other processes, RFID tags may be damaged in this link, so that can not communicate with the outside world. The position of the RFID tag in the tire can be clearly seen by X-ray examination. The test results show that for the newly produced RFID tires, the reading distance of the RFID electronic tag in the middle of the tire side is far, because the tire is thin and has little interference to the radio frequency signal. The reading distance of RFID tags near the tire side to the child mouth and the tire shoulder position is relatively close. For the tires that have finished the road test, the RFID tags in the middle of the tire side and the tire shoulder position cannot be read, but they can be read near the subport. By dissecting the test tire after road test, it can be found that the antenna of RFID electronic tag and the chip appear false welding. The reason is that the middle of the tire tire side is bent and deformed greatly, so that the antenna structure of the electronic tag is damaged and the signal transmission of influence is damaged. 3.3 dynamic balance uniformity test The dynamic balance uniformity of tires directly affects the ride stability and safety of tires. With the help of the dynamic balance uniformity testing equipment, we detect the tires implanted with RFID electronic tags. The results show that the actual mass of RFID electronic tags is only 0.02g, which will not affect the dynamic balance uniformity of tires after implantation. 3.4 durability test and road test In order to ensure the safety of the test, indoor mileage test should be carried out before the actual road test of RFID test tires. The conventional durability test results show that the RFID test tire will not be affected by the implanted RFID tags. Indoor tire durability test qualified before road test. The road test results show that the tires are running in various practical road conditions, RFID tags will not affect the quality of tires, at the same time, it can ensure that the data stored in the chip can be read normally after the tires are used, realizing the tracking management of the whole life cycle of tires. 4 conclusion Electronic tag is verified by experiment the best implant position and implantation methods, focusing on the reliability of the electronic label detection are studied, mainly through the uniformity of the bubble, X-ray, dynamic balance, durability test and road test was carried out on the test tire detection test, the test results can be concluded that RFID tags in the tires will not affect the quality and safety performance of the tire.
