Device and method for preparing array patterns based on static spray printing

Abstract

The invention discloses an array pattern spray printing device based on electrofluid power spray printing. The array pattern spray printing device comprises a metal needle head, a printing layer, a metal substrate, a motion platform and a high-pressure generator, wherein the metal needle head is arranged above the printing layer; the printing layer is arranged on the metal substrate; the metal needle head and the metal substrate are connected to the positive end and the negative end of the high-pressure generator, so that an electric field is formed between the metal needle head and the metal substrate; the metal substrate can be driven to do plane motion by the motion platform so as to drive the printing layer to do motion; and a spray printing solution flows out the metal needle head and forms jet flow to be sprayed to the printing layer which does motion under the action of the electric field, so that the required spray printing patterns can be formed on the printing layer. The invention also discloses a method for preparing the patterns by utilizing the device. According to the device and the method, the high-accuracy array patterns can be manufactured simply and quickly under the engineering environment on the basis of stretching-assisted high-accuracy positioning, so that the limit of the conventional static spray printing technology in aspects of jet flow positioning and the spray printing of the specific patterns is broken through.

Description

Technical field [0001] The invention relates to a high-precision arrayed pattern prepared by using electrostatic spinning technology and a preparation method and device thereof, belonging to the technical field of electronic manufacturing electrojet printing. Background technique [0002] As a manufacturing process tool, the application of inkjet printing technology can be traced back to the 1950s when Siemens used it for machine output trajectory management. More development took place during the period of 1960 to 1980. It has been widely used in many fields, including: image output and marking. Traditional inkjet printing technology mainly uses continuous inkjet printing (CIJ) and on-demand inkjet printing (DOD). Both inkjet printing technologies can produce droplets with a diameter in the range of 20-150 microns: CIJ is mainly used for coding and For marking, the droplet diameter is about 100 microns; DOD is mainly used in image and text printing, and the droplet diameter is ...
