Abstract

The invention discloses a near-field electrostatic jet-printing head, relating to the electrostatic jet-printing head. The invention provides the near-field electrostatic jet-printing head with low-voltage driving and capability of jetting and printing micro-nano pattern structures accurately. The near-field electrostatic jet-printing head is provided with a laser generator, a computer, an electromagnetic valve, an air guide pipe, a sealing head, a jet pipe, a conducting probe and an air pipe, wherein the laser generator generates laser beams; the computer is connected with the electromagnetic valve and the laser generator; the upper end of the jet pipe is provided with an outer thread, and the lower end of the jet pipe is a jet nozzle; the sealing head is in threaded connection with the outer thread of the upper end of the jet pipe by an inner thread; the air pipe is positioned in the jet pipe and is fixed on the sealing head; one end of the air pipe is connected with the output end of the electromagnetic valve by the air guide pipe, and the other end of the air pipe is an air outlet with a reducing structure; the air outlet is coaxial to the jet nozzle; and one end of the conducting probe is fixed on the sealing head and is connected with a positive electrode of a direct-current voltage source, and the other end of the conducting probe extends out of the end part of the jet nozzle.

Description

technical field [0001] The invention relates to an electrostatic printing head, in particular to a near-field electrostatic printing head which can realize low-voltage driving and high-precision printing based on electro-hydraulic dynamics. Background technique [0002] Micro-nano patterned structure, device manufacturing and its application have become research hotspots in the international micro-nano field. Traditional MEMS silicon-based manufacturing processes (such as deposition, photolithography, and etching, etc.) are difficult to meet the low cost and large size (~m) of products based on micro-nano patterned structures due to their high manufacturing costs and harsh environmental requirements Manufacturing requirements greatly restrict the application range of micro-nano patterned products. For example, flexible electronics, as an emerging industry in my country in the future, requires low cost, large size and flexible substrates, but MEMS technology cannot be applied ...
