Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] As we all know, RFID tags are widely used in logistics, drug supervision, public service, animal husbandry and other aspects due to their advantages such as large storage data capacity, long reading distance, data encryption on the tag, and free change of stored information. Moreover, its reliable anti-counterfeiting and fast reading are also decisive factors for its gradual replacement of barcodes. Its anti-counterfeiting is mainly because each RFID chip has a unique ID number, which is solidified inside the chip by the manufacturer and cannot be rewritten. In addition, only one barcode ca...

Abstract

The invention discloses a method for online detecting an RFID electronic tag. The method particularly comprises the steps of setting up the mapping relation of the ID numbers of RFID chips in a working position and the position of the tag in real time in the process of carrying out RFID chip packing on the working position, simultaneously reading the ID of all the RFID chips in the working position after working position packing is completed, comparing the read ID of the RFID chips with the mapping relation of the ID of the RFID tags in the working position and the positions of the RFID tags, confirming ID with missing reading, and confirming that the tag corresponding to the ID is an inferior-quality product. The invention further provides a device for online detecting the RFID electronic tag. The device comprises an X-direction feed mechanism, a Y-direction feed mechanism, a reader-writer, a processor, a marking mechanism, a clamping mechanism and a shielding case. The method and device can complete the read-write and signing functions of multiple tags, is suitable for online detection of the RFID tags with multiple lines and multiple columns, can greatly improve detecting efficiency, and is high in automation degree, stable and reliable.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification (RFID) electronic tags, in particular to an online detection method and device for RFID tags. Background technique [0002] The commonly used flip chip (Flip Chip) packaging process in RFID label production includes substrate transportation, dispensing, mounting, hot pressing, and testing. The specific steps are: 1. The dispenser drops an appropriate amount of conductive glue to the RFID antenna On the pad of the substrate; 2. The placement head picks up the RFID chip and places it on the pad of the antenna substrate; 3. Use the thermal head to make the conductive adhesive solidify under the simultaneous action of pressure and heat, so as to realize the mechanical connection between the antenna and the substrate and electrical connection; 4. Check whether the finished product of the label meets the requirements for use, and mark the defective product. [0003] The online de...
