DEVICE FOR RFID MARKING OF PLASTIC SEALING DEVICES Russian patent published in 2022 - IPC E05B39/02 G09F3/03 

FIELD: radio engineering.

SUBSTANCE: invention relates to the field of radio engineering; it can be used in the manufacture of plastic sealing devices (indicator seals) with their radio frequency identification. Device (1) for RFID marking of block (2) of at least two interconnected identical plastic sealing devices (3) separated by separation line (5) with jumpers on the border of two adjacent sides is a plate formed by at least two interconnected identical segments having outer and inner sides. The width of each segment in the plate corresponds to the width of marking plane (13) of each of sealing devices or is less than it. Separation line (5) with cutouts is made on the border between segments. Each segment on the inner side contains an RFID mark fixed and not protruding beyond edges of the segment and gaps. The plate is made of material analogue or similar in composition to material of the sealing device. Each segment is made with the possibility of welding its inner side to the marking surface of the case of the corresponding sealing device along the perimeter of the segment. Separation line (5) between segments of the plate is made of a reciprocal separation line between two sealing devices corresponding to segments of the plate.

EFFECT: reliability of the radio frequency identification of the sealing device is improved, the process of integrating the RFID (radio frequency) mark into a series of sealing devices integrated into a block is simplified and accelerated, and the service life of the RFID mark integrated into the sealing device is increased.
