Description

RFID high-frequency reader-writer Technical Field The utility model relates to the technical field of readers, in particular to an RFID high-frequency reader. Background The RFID high-frequency reader-writer is used as key equipment for realizing non-contact information identification and data transmission, plays an important role in the fields of intelligent warehouse management, logistics tracking, new retail unmanned settlement and the like, and is communicated with a tag through radio frequency signals to complete data reading and writing operation, so that the efficiency and accuracy of information acquisition are greatly improved, the application scene of the RFID high-frequency reader-writer is continuously expanded along with the rapid development of the Internet of things technology, the requirements on the performance and the stability of the RFID high-frequency reader-writer are increasingly improved, and research and development personnel are promoted to continuously explore the optimization and upgrading of the mechanical structure and the function of the reader-writer. At present, in the mechanical structural design of the common RFID high-frequency reader-writer in the market, the traditional fixed connection mode is mostly adopted, the antenna and the reader-writer main body are connected in a mode of screw fastening or welding, when the circuit connection is carried out, the jack part is usually of an open structure, no additional fixing and protecting measures are needed, the circuit connection is manually inserted by manpower and limited through a simple interface shape, the disassembly and assembly of the antenna is carried out by screw disassembly by means of tools such as a screwdriver or the like or a special device is used for processing welding points, the design is based on a simple mechanical fixing principle, the stability of the device structure is guaranteed to a certain extent, and however, a plurality of limitations exist in practical application.
