TECHNICAL FIELD
[0001] The utility model relates to printing device technical field, especially a printer auxiliary device of RFID label. BACKGROUND
[0002] With the development of the times, the application range of RFID technology is more and more wide. From the box level to the single product, from luxury goods to ordinary fast consumables, from parcel set bag to ordinary parcel, the requirement of RFID label cost is lower and lower. At the same time, the application of single RFID label needs to carry more and more associated data. Due to the fact that the internal storage space of the label chip is proportional to the chip cost, from the future application trend, the label chip does not store user data, only saves a unique identification number, and the task of storing associated user data is placed in the cloud, and the application is inquired through the unique identification number, which is the final solution to the problem.
[0003] Based on this cognition, we have cut the general international standard 18000-6C protocol of RFID technology, removed the relatively complex read, write, lock and other operations, only reserved Select and Inventory instructions, and removed the user memory, combined EPC and T ID, and planned a truly read-only RFID chip. At present, many companies have produced this type of chip, for example, the ONLY series of ultra-high frequency read-only chips of Sichuan Kailuwei Technology and the Yuzhan 600 chip of Pingtouge Semiconductor Company under Alibaba, which have achieved good response in the market.
[0004] However, in the actual project application, such ultra-high frequency read-only RFID labels cannot be compatible with the existing RFID special printers in the market. This is because the RFID special printer has formed a set of positioning, identification, writing and checking mechanism based on T ID after years of development. The cut communication protocol corresponding to the read-only RFID label cannot meet the requirements of the mechanism. CONTENT OF THE UTILITY MODEL

At the same time as the label is printed, the RFID reader / writer body can identify the unique identification number inside the label and associate it with the printed data on the label surface, enabling the regular label printer to support RFID function, expanding the application range of the label printer, and thus improving the functionality of the device. With the set of a freely detachable and adjustable bracket, the height of the bracket can be adjusted arbitrarily, thus adapting to most printers on the market and increasing the compatibility of the device. In addition, the bracket can be detached and installed in reverse, with the main body of the bracket facing backward, so that it can be hung on the bottom of the printer.
