Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] see figure 1 , an RFID tag online detection device, mainly by the X-direction feeding device 10, the Y-direction feeding device 20, the ink dispensing device 30, the reading and writing device 40 and the ink dispensing device 50.

[0034] see figure 2 , the X-direction feeding device 10 is mainly composed of an X-direction servo motor 104 , a ball screw assembly 101 , an X-direction rail 102 and an X-direction adapter plate 103 . The X-direction servo motor 104 directly drives the ball screw assembly 101 to convert the rotation of the motor into the X-direction linear motion of the X-direction connecting plate 103 . The Y-direction bottom plate 210 is fixedly connected with the X-direction connecting plate 103 , and the other end is installed on the X-direction rail 102 slider.

[0035] see image 3 , the Y-direction feed device 20 is composed of a synchron...

Abstract

The invention discloses an online detection device for an RFID (Radio Frequency Identification Device) label. The device comprises an X-direction feed mechanism for adjusting the position of a Y-direction feed mechanism in the X direction of the horizontal plane; the Y-direction feed mechanism located on the X-direction feed mechanism for adjusting the position of a read-write mechanism in the Y direction of the horizontal plane; the read-write mechanism located on the Y-direction feed mechanism for online reading data of the RFID label; an ink spotting moveable mechanism located on the Y-direction feed mechanism for moving the plane of an ink spotting mechanism to an unqualified RFID label; and the ink spotting mechanism located on the ink spotting moveable mechanism for spotting and marking the unqualified RFID label. The device provided by the invention can realize label reading and writing and spotting and marking functions at the same time, is suitable for online detection of multi-row and multi-line RFID labels, and has the advantages of automation, high efficiency and stability and reliability.

Description

technical field [0001] The invention relates to the technical field of optical-mechanical-electrical integration, in particular to an RFID tag online detection device. Background technique [0002] With the development of science and technology, RFID tags have been used more and more widely. On-line inspection of finished products after RFID tags are packaged is an important part of it. Unqualified RFID tags are marked with ink. The existing RFID tag online detection device is equipped with a reader and ink dispensing device for each label in each row, and completes the online detection of multiple RFID tags in a single row at the same time, but this method increases the cost, and the distance between multiple readers is relatively long. Close, prone to interference and false detection. [0003] Patent CN202205221U provides an RFID tag online detection device, which adjusts the position of the RFID tags placed on the detection frame through a horizontal two-dimensional adju...
