Full-automatic detection and label changing device for graphene RFID label

Abstract

The invention discloses a graphene RFID label full-automatic detection label changing device. The device comprises a power mechanism, a detection mechanism, a buffer temporary storage mechanism and alabel changing mechanism, wherein the power mechanism comprises a first power roller and a second power roller; the detection mechanism is used for detecting the graphene RFID tag; the buffer temporary storage mechanism is arranged between the detection mechanism and the second power roller and comprises a speed reduction roller and an adjusting piece so as to increase or decrease the conveying stroke of the bottom film between the movable roller and the fixed roller; the label changing mechanism is arranged between the buffer temporary storage mechanism and the second power roller, the labelchanging mechanism comprises a label changing piece and a label changing platform, the label changing platform is used for bearing a bottom film, and the label changing piece can replace detected unqualified graphene RFID labels with qualified graphene RFID labels. According to the device, accumulation of the bottom film attached with the graphene RFID tag during tag replacement can be prevented,and tag replacement efficiency is high.

Description

technical field [0001] The invention relates to the technical field of graphene RFID tags, in particular to a graphene RFID tag automatic detection and relabeling device. Background technique [0002] Graphene paste can be printed on almost all substrates such as plastic film and paper, and has good conductivity. More and more manufacturers use graphene paste to print graphene RFID tags. The graphene RFID tag is the data carrier of the RFID system, which is directly bound to the object to be identified. It is the medium for system information identification and data collection. It is particularly important to detect the performance of the graphene RFID tag. [0003] Graphene RFID tags are usually attached to a backing film for storage and sale in rolls. The detection device usually includes a power roller to transport the bottom film attached to the graphene RFID label to the detection mechanism. When the detection mechanism detects an unqualified graphene RFID label, the p...

Problems solved by technology

However, after the power roller reduces the operating speed, the base film still moves at the original speed within a certain period of time, causing the base film to accumulate and wrinkle, so as to damage the graphene RFID label

In addition, it is difficult to control the pressure when the unqualified graphene RFID label is removed from the bottom film by the label changing mechanism of the existing technology, and the reliability and efficiency of label changing are low.
