Technical Field

[0001] The utility model relates to the technical field of electronic tag positioning and identification, and particularly relates to an electronic tag accurate coverage positioning device. Background Technique

[0002] By pasting electronic tags on logistics goods, real-time tracking of the goods can be realized, so that the position and transportation progress of the goods can be understood at any time through the monitoring system whether during transportation or in the warehousing link.

[0003] On the package conveyor line of logistics, usually an RFID reader / writer is fixed on one side of the conveyor belt to identify the electronic tags on the passing packages, so as to realize the inbound and outbound management. During the process of using the conveyor belt for the logistics packages, due to the uneven distribution of the items in the packages, the packages are prone to tilt in position under the offset of the center of gravity. Since the electronic tags usually need to be within a certain angle range to be effectively identified by the RFID reader / writer, when the packages tilt on the conveyor belt, it will drive the electronic tags to tilt, and the tilted electronic tags exceed the optimal identification angle range of the RFID reader / writer, resulting in the failure of the radio frequency signal of the RFID reader / writer to fully cover the electronic tags, thus affecting the accuracy of the identification of the electronic tag information.

[0004] Therefore, there is an urgent need for an electronic tag accurate coverage positioning device to solve the above problems. Content of the Utility Model

[0007] The positioning mechanism includes two symmetrically arranged mounting frames slidably connected to the U-shaped plate. The two mounting frames are arranged in a "V" shape. Two mounting grooves are formed on the two mounting frames. Four positioning wheels are connected to the four mounting grooves through rotating shafts. A driving mechanism for driving the four positioning wheels is arranged on the U-shaped plate.

[0008] The four positioning wheels are made of rubber material.
