Description

Graphene RFID antenna printing device

Technical Field

The invention belongs to the technical field of printing, and particularly relates to a graphene RFID antenna printing device.

Background

The manufacturing of the conventional RFID antenna is mainly realized by etching, which specifically includes: pressing a metal foil on the plastic film, and coating a photosensitive film on the metal foil; after drying, illuminating the antenna pattern by an exposure device with the antenna pattern to be formed, thereby developing the antenna pattern on the photosensitive film; washing the undeveloped part of the photosensitive film, so that part of the area on the metal foil is covered by the developed photosensitive film, and part of the area is uncovered; then putting the film into an acid etching pool, and corroding the metal foil which is not covered by the photosensitive film; and finally, the photosensitive film is removed, so that the antenna coil corresponding to the shape of the antenna pattern is obtained. The antenna is produced by etching, which is a complicated procedure, although the technology is mature; metal foil is wasted, and the cost is high; the acidic waste liquid is difficult to treat and has strong destructiveness to the environment; the precision of the chip binding part in the antenna is low and cannot reach the precision level of about 0.2mm, so that an extra connecting extension piece is needed to connect the chip with the corresponding precision.

Therefore, the mode of printing the RFID antenna by adopting the conductive paste comes from the beginning, and particularly, the conductive paste is printed on the base materials such as PET (polyethylene terephthalate) by adopting the modes such as screen printing, flexographic printing, intaglio printing and the like, so that a conductive circuit is formed, and then the RFID antenna is formed, so that the environmental protection and the cost are greatly improved.

In the prior art, the raw materials for processing the RFID antenna mostly adopt conductive silver paste, and although the conductivity of the raw materials is better, the cost is higher. At present, graphene conductive paste with the advantages of excellent conductivity, ductility, fluidity, low cost and the like gradually replaces conductive silver paste to be used as a raw material for processing an RFID antenna. However, the method of printing the RFID antenna with the graphene conductive paste has the following disadvantages: the resistance and shape of the antenna circuit are unstable. Moreover, the accuracy of the RFID antenna is greatly affected by the parameters of the graphene conductive paste, such as concentration and component ratio, which are difficult to control, and the characteristic of the graphene material that is prone to agglomeration.

In addition, with the continuous progress of the RFID electronic tag technology, the requirements of users on RFID antennas are higher and higher, and RFID antennas with more complex shapes, higher precision requirements and greater processing difficulty are designed continuously. The existing printing equipment is also increasingly laboured in printing the RFID antenna with more complex shape, higher precision requirement and more difficult processing.

It will thus be seen that the prior art is susceptible to further improvements and enhancements.
