Arrayed electrofluid jet printing head with independently controllable nozzle ejection and its realization method

Abstract

The invention discloses an array electric fluid jet printing head characterized by independently controllable nozzle jet. The array electric fluid jet printing head comprises a guide electrode layer arranged between a nozzle array and a receiving plate, and a plurality of round holes corresponding to nozzles in number are formed in the guide electrode layer; the centers of the round holes are collinear with the centers of the nozzles; a circle of conducting ring is coaxially disposed on the outer periphery of each round hole in the guide electrode layer, and is connected with one voltage source; and the nozzle array is connected with the jet voltage sources; and the voltage value of each voltage source is properly adjusted, so that the voltage differences of the nozzles required for jet printing and the corresponding conducting rings are greater than the voltage differences of the remaining nozzles, the field strength of the nozzles for jet is greater than the field strength needed to start the jetting, the field strength of the nozzles not required for jetting is lower than the field strength needed to start the jetting, and the independent control of all the nozzles can be realized. The invention further discloses a realization method of the independent control of the jet of the nozzles. The array electric fluid jet printing head and the realization method can solve the problems of complex structure and incapability of large-scale integrated use in the conventional independent jet control to printing heads.

Description

Technical field [0001] The invention relates to the technical field of electrofluid jet printing, in particular to an arrayed electrofluid jet printing head and a method for achieving independent controllable jetting of the arrayed electrofluid jet printing head. Background technique [0002] Complex micro-scale structures can be used in many fields, such as printed electronics, organic / flexible electronic devices, multi-function sensors, etc. Therefore, in recent years, their preparation processes have attracted much attention. Both inkjet printing and electrofluid printing, as non-contact patterning processes, can deposit micro-scale structures on the substrate, and compared with photolithography-type patterning processes, it has the advantages of no mask, material saving, environmental friendliness, and convenient operation. , Which is considered the best solution. However, traditional inkjet printing technologies (such as piezoelectric printing and thermal bubble printing) u...
