RFID tag information input device

Abstract

An RFID tag information input device for an RFID printer for inputting information in an RFID tag (20) which is mounted on an RFID printer (10) and continuously transferred, according to the present invention, comprises: a housing unit (110) which provides a moving space (116); an antenna module (120) which is arranged in the moving space (116), transmits a wireless signal to the RFID tag (20), which is transferred to an input position (I), and receives a response signal corresponding to the wireless signal; a module moving unit (130) which is connected to the antenna module (120) and adjustsa position of the antenna module (120) while moving the antenna module (120) horizontally with respect to an x-axis and a y-axis on a horizontal surface within the moving space (116); and a control unit (160) which calculates an optimal position (P) of the antenna module (120) for wireless communication on the basis of the response signal, which is received by the antenna module (120) moving at aconstant interval (d1) along the x-axis, and the response signal, which is received by the antenna module (120) moving at a constant interval (d2) along the y-axis, moves the antenna module (120) to the calculated optimal position (P), and controls each RFID tag (20) to input the tag information.

Description

technical field [0001] The invention relates to a radio frequency identification label information input device, in particular to a radio frequency identification issuing device installed on a radio frequency identification printer or a radio frequency identification issuer, through which radio frequency identification rolls are used to input labels on each video identification label continuously transferred RFID tag information input device for information. Background technique [0002] Generally speaking, RFID (Radio Frequency IDentification), that is, radio frequency identification technology, is a technology that pastes a radio frequency identification RFID with a built-in small chip on various items, and transmits and processes various stored label information with wireless frequencies. . It is said to be a technology that replaces barcodes without direct contact or scanning within the visible range like barcodes, and related technology development is also actively pro...

Problems solved by technology

[0006] However, in the radio frequency identification tag information input device in the prior art, the installation position of the aforementioned antenna module is fixed, depending on the size of the supplied radio frequency identification tag or the shape of the internal antenna, when the identification position of the radio frequency identification tag is different, it will automatically From the position where the radio frequency identification supply starts to the position where the antenna module is fixed, each radio frequency identification tag moves back and forth, and information input may be performed at different optimal positions. For most radio frequency identification tag information input devices, the input tag The radio frequency identification tags of information are very limited, and have the problems of interchangeability and low versatility

[0007] In addition, the position of the antenna module is fixed. In the radio frequency identification tag information input device, in order to input the tag information, the position of the radio frequency identification tag must be moved back and forth. During the movement, friction, impact and vibration may occur. The internal antenna pattern and the memory chip are damaged
