Safe RFID electronic tag with dust removal function

Abstract

The invention relates to a safety type RFID electronic tag with a dust removal function. The safety type RFID electronic tag comprises a protective shell, a label, a storage mechanism and two dust removal mechanisms, the storage mechanism comprises a driving assembly, a connecting plate and two storage assemblies. The storage assembly comprises a lead screw, a fixing rod, a torsion spring and twofirst bearings. The dust removal mechanism comprises a roller brush, a rotating shaft, two fixed blocks, two first springs and two second bearings. According to the safety type RFID electronic tag with the dust removal function, the tag can be stored in the protective shell through the storage mechanism, the damage probability of the tag is reduced, the safety is improved, the dust removal work ofthe tag is achieved through the dust removal mechanism, and the situation that the dust covers the tag, and the scanning effect of the tag is affected is avoided.

Description

technical field [0001] The invention relates to the radio frequency field, in particular to a safe RFID electronic tag with dust removal function. Background technique [0002] Electronic tags are also called radio frequency tags, transponders, and data carriers; readers are also called readout devices, scanners, reading heads, communicators, and readers (depending on whether the electronic tags can rewrite data wirelessly). The space (non-contact) coupling of radio frequency signals is realized through the coupling element between the electronic tag and the reader; in the coupling channel, energy transmission and data exchange are realized according to the timing relationship. [0003] The existing electronic tags are generally exposed, which increases the probability of damage to the electronic tags and reduces the safety of the electronic tags. Not only that, because there is no blocking device, the dust is easy to cover the electronic tags, which affects the scanning eff...
