Passive RFID visual card printer

Abstract

The invention discloses a passive RFID visual card printer. The passive RFID visual card printer comprises a metal upper frame body and a metal lower frame body, wherein the upper frame body is provided with a visual printing head and upper rollers, a cavity is formed between the upper frame body and the lower frame body, the cavity is internally provided with lower rollers, an electronic label passes through the portions between the upper rollers and the lower rollers, an antenna is arranged above the lower frame body, a ferrite membrane is arranged at the surface, which is oriented towards the lower frame body, of the upper frame body, and a ferrite membrane is arranged at the surface, which is oriented towards the upper frame body, of the lower frame body. Through such a design of the visual card printer, since the ferrite membranes can reduce absorption of a signal magnetic field by a metal material, the eddy current attenuation effect applied by the metal upper frame body and the metal lower frame body to the signal magnetic field can be effectively reduced, additional arrangement of a plastic housing is unnecessary, and the structural design is simple; and at the same time, the ferrite membranes are ferrite materials sintered at a high temperature so that the signal magnetic field intensity can be enhanced, the induction distance is effectively increased, the internal space is compact, and the work efficiency is high.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to a passive RFID visual card printer. Background technique [0002] Radio frequency identification technology (RFID) is a new technology developed in recent years. Radio frequency identification cards are gradually replacing traditional contact IC cards. They have the characteristics of long life, high security and confidentiality, and easy use. The two-way communication rate has also been greatly improved. Combining the radio frequency identification card with heat-sensitive materials to obtain a visual card, the information stored in the media in the card and the software system is printed on the surface of the card in the form of text and patterns through a special visual card printer and permanently left on the card surface. It cannot be erased and reprinted until the next time a visual card printer is used to visualize information. [0003] However, since most video card pr...

Problems solved by technology

[0003] However, since most video card printers are made of metal, the alternating electromagnetic field induced by the signal emitted by the antenna is easily affected by the eddy current attenuation of the metal and the signal strength is greatly weakened, resulting in the failure of the reading and writing process, and the difficulty of radio frequency technology. application

as attached figure 1 As shown, in the prior art, an additional plastic case 100 is generally installed at one end of the printer to install the electronic label 101 and the antenna 102, which increases the space and cost of the printer, and also brings great trouble to the appearance design.
