Electromagnetic printing nozzle, electromagnetic printing device and printing method

Abstract

The invention provides an electromagnetic printing nozzle, an electromagnetic printing device and a printing method, wherein the electromagnetic printing nozzle comprises at least one nozzle assembly,and the nozzle assembly comprises a nozzle, a positive electrode, a negative electrode, a first magnet, a second magnet and a film pipe. The positive electrode and the negative electrode are oppositely disposed, and the N magnetic pole of the first magnet is vertically opposite to the S magnetic pole of the second magnet. The film pipe is vertically placed in a space formed by the positive electrode, the negative electrode, the first magnet and the second magnet, and the nozzle is in communication with the film pipe. The electromagnetic printing nozzle employing the electromagnetic drive principle enables the whole electromagnetic printing device to be simple in structure, to be easy to control, to be high in printing precision, and to be high in speed. Meanwhile, the electromagnetic printing device can be used for printing of liquid metal ink, and is especially suitable for the manufacturing of printed circuits, such as the production of flexible circuits, skin electrons and sensors.

Description

technical field [0001] The present invention relates to the technical field of printing, and more specifically, to an electromagnetic printing nozzle, an electromagnetic printing device and a printing method. Background technique [0002] Printers are indispensable electronic devices in our daily life. In industrial production, clothing manufacturing, product packaging and other fields, printing technology also has a wide range of applications. With the development of technology, traditional pattern printing can no longer meet people's needs, and functional printing technology has been widely concerned and applied. Such as adhesive printing, photoresist printing, etc. [0003] Among various printing technologies, the printing of conductive ink is one of the research hotspots. By printing conductive inks directly onto substrate materials, functional circuits can be formed. This feature has broad application prospects in electronic tags, flexible circuits, skin electronics ...

Problems solved by technology

[0006] On the other hand, the existing printing technology is gradually developing in the direction of multi-nozzles. Often there are dozens or even tens of thousands of nozzles on one print head. It is difficult for the traditional mechanical structure to adapt to this arrayed nozzle design, which limits the printing speed. and further improvements in accuracy
