RFID label detection equipment

Abstract

The invention provides RFID label detection equipment used for carrying out detection upon RFID labels. The equipment comprises a frame, and an unreeling unit and a reeling unit respectively arranged on the two ends of the frame. A label conduction detection unit, a vision detection unit and a label changing platform are successively arranged between the unreeling unit and the reeling unit. Paper-guiding rollers are arranged between the units. The label conduction detection unit is arranged between the unreeling unit and the vision detection unit. According to the RFID label detection equipment provided by the invention, the printing quality of the labels, including variable information in the printed information, is detected by using the vision detection unit. The conduction performance of the labels is detected by using the label conduction detection unit. The unqualified labels are replaced by using the label changing platform. Therefore, efficiency and accuracy of the detection, and quality of the products can be ensured.

Description

Technical field [0001] The invention relates to a detection device, in particular to an RFID tag detection device. Background technique [0002] With the development of science and technology, RFID tags have been more and more widely used. Because RFID tags are read and written through radio frequency identification technology, good printing quality and good physical characteristics are crucial to their use. The existing printing quality inspection uses manual methods. The usual method is: the inspector places the cut small roll labels on the rewinder and keeps it running at a low speed. The operator observes the appearance quality of the electronic labels with the naked eye and is qualified. The electronic tags will be rewound, and the electronic tags with quality problems will be shut down immediately and removed. There are many shortcomings in manual detection methods. The two most critical points are low detection efficiency and the inability to guarantee the stability of qu...

Problems solved by technology

Existing testing of printing quality adopts manual methods. The usual method is: inspectors place the cut labels on the rewinder and keep it running at a low speed. Operators observe the appearance quality of the electronic labels with naked eyes. The electronic labels will be rewinded, and the electronic labels with quality problems will be immediately shut down and removed

There are many shortcomings in the manual detection method, the two most critical points are the low detection efficiency and the inability to ensure the stability of quality detection at all times

The reason why the detection efficiency is low is that most of the electronic tags have small images and texts. If the detection speed is slightly faster, the naked eye will often be unable to distinguish some small defects, resulting in missed detection.

There is also a way to detect the surface printing quality of RFID tags through testing equipment, but this method can only detect the surface printing quality of RFID tags, and cannot reliably fix and contact physical characteristics between the chip and the antenna. to test
