Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of radio frequency tags, and particularly relates to a composite film structure of a radio frequency tag. Background Art
[0002] Generally, radio frequency identification (RFID) technology refers to a technology that uses radio waves to wirelessly identify information at a position separated by a specified distance. In order to implement RFID technology, an RFID tag and an RFID reader are required. The RFID tag includes an antenna and an RFID chip as an integrated circuit, and after necessary information is pre-recorded in the RFID chip, the information is transmitted to the reader through the antenna. The information usually stored in the RFID chip is used to identify the object to which the RFID tag is attached.
[0003] The difference between RFID and a barcode system is that RFID uses radio waves to read RFID instead of light. Therefore, it can not only work not only at a short distance like a barcode reader, but also can read tags at a long distance, and even has the advantage of being able to penetrate objects that do not ensure a visible distance to receive information.
[0004] This kind of RFID tag is suitable for the production management and inventory management of various products. In particular, it is widely applicable to the tire manufacturing process and inventory management process. When manufacturing tires, in order to use an enterprise resource planning (ERP) system such as production management or inventory management after manufacturing, when an RFID tag is attached or buried starting from the molding step of manufacturing tires, as the RFID tag is exposed to the harsh manufacturing environment of the vulcanization process as a subsequent process, that is, a high-temperature environment of 150°C to over 230°C and a high-pressure environment of over 30 Bar, there will be a problem that the RFID tag is damaged in the manufacturing process.
[0005] Existing ones still have some defects, mostly with poor stability. In the environment of high-speed rotation of tires and the subsequent high temperature, high pressure environment, as well as the environment where repeated stress caused by deformation is applied, the chip area of the RFID tag is damaged, or normal communication cannot be carried out, so that the RFID tag in the attached state may fall off the tire. For this reason, we propose a composite film structure of a radio frequency tag. Summary of the Utility Model
[0006] The purpose of the utility model is to provide a composite film structure of a radio frequency tag to solve the problem of poor stability proposed in the above background art.
[0007] To achieve the above object, the present utility model provides the following technical solutions: a composite film structure of a radio frequency tag, including a protective shell and a base. The base is disposed inside the protective shell, and the base is fixedly connected to the protective shell. The base has a certain ductility. A buffer seat is provided on the top of the base, a buffer groove is embedded on the top of the buffer seat, a buffer block is provided inside the buffer groove, the buffer block is slidably connected to the buffer groove, a support rod is provided on the top of the buffer block, the support rod is rotatably connected to the buffer block, a connecting member is provided at one end of the support rod, the support rod is rotatably connected to the connecting member, a spring is provided inside the buffer groove, and a fixing plate is provided on the top of the connecting member.
[0008] Preferably, a base film is provided on the top of the fixing plate, the base film is fixedly connected to the fixing plate, and an identification chip is provided on the surface of the base film.
[0009] Preferably, a first adhesive layer is provided on the top of the identification chip, the first adhesive layer is fixedly bonded to the identification chip, and a protective layer is provided on the top of the first adhesive layer.

[0022] Please refer to Figures 1-3 , the present utility model provides a technical solution: a composite film structure of a radio frequency tag, including a protective shell 1 and a base 2. The base 2 is provided inside the protective shell 1, and the base 2 and the protective shell 1 are fixedly connected. The base 2 has a certain ductility. A buffer seat 3 is provided on the top of the base 2. A buffer groove 4 is embedded in the top of the buffer seat 3. A buffer block 5 is provided inside the buffer groove 4. The buffer block 5 is slidably connected to the buffer groove 4. A support rod 6 is provided on the top of the buffer block 5. The support rod 6 is rotatably connected to the buffer block 5.

A fixing plate 9 is provided on the top of the connecting piece 7.
[0023] In this embodiment, when using the composite film structure of the radio frequency tag, the device is fixed to the inner wall of the tire. Through the provided protective shell 1 and base 2, the distance between the tire and the identification chip 12 can be separated, so that the heat generated by the tire will not directly contact the identification chip 12, and the use is safer. When the tire undergoes high-pressure deformation, it will drive the base 2 to deform, thereby driving the buffer block 5 to slide inside the buffer groove 4, and then driving the support rod 6 to rotate. At this time, the spring 8 is compressed to maintain the stability of the identification chip 12, so that it will not deform following the tire, not only is it not easy to fall off, but also the stability of the identification chip 12 is ensured.
[0024] Specifically, a base film 10 is provided on the top of the fixing plate 9. The base film 10 is fixedly connected to the fixing plate 9. An identification chip 12 is provided on the surface of the base film 10. A first adhesive layer 13 is provided on the top of the identification chip 12. The first adhesive layer 13 and the identification chip 12 are fixedly connected by adhesion. A protective layer 14 is provided on the top of the first adhesive layer 13. A second adhesive layer 15 is provided on the bottom of the protective shell 1. The second adhesive layer 15 is fixedly connected to the protective shell 1. A protective film 16 is provided on the bottom of the second adhesive layer 15. The protective film 16 and the second adhesive layer 15 are fixedly connected by adhesion. There are four groups of buffer blocks 5, springs 8 and support rods 6, which are respectively located on both sides of the buffer seat 3. A circuit pattern 11 is provided on the surface of the base film 10. The circuit pattern 11 and the base film 10 are fixedly connected by welding.
[0025] In this embodiment, the first adhesive layer 13 and the protective layer 14 provided can play a protective role for the base film 10. The second adhesive layer 15 and the protective film 16 provided facilitate the installation of the protective shell 1. During installation, tear off the protective film 16 and paste the second adhesive layer 15 on the inner side of the tire to complete the installation, which is time-saving and labor-saving.
