Abstract

The present invention is directed to a method for online real-time detection and control of the line segments and graphics of the jet printing in the process of electro-fluid jet printing. Control and determine the printed current and the distance of the near field to achieve the goal of printing line segments or patterns. In the present invention, the steady-state variation law of the measurement points and the motion variation of the printing platform are used to measure and analyze the measurement points as the basis for forming systematic errors. The precise measurement of the line width of the line segment is realized through the multi-point measurement, and artificial intelligence is used to change the graphics. Observation, using CCD camera system and video acquisition interface circuit to complete the observation and processing of graphic workpieces. The diameter of the conical liquid formed by the electro-fluid jet printing probe is 0.001mm-100mm, the voltage provided by the high-voltage power supply is 1-100kV, the distance of the near electric field is 1-300mm, and the diameter of the sprayed nanofibers is 1-1000nm. The invention has the characteristics of high precision control, easy formation of nanometer-level line width, and formation of various complex graphic structures.

Description

technical field [0001] The invention relates to the technical field of electrofluid jet printing, in particular to an on-line detection and control method for jets formed during electrofluid jet printing and patterns of electrofluid jet printing fibers. Background technique [0002] The electrofluid printing technology is that the charged polymer solution (or melt) is stretched to form a jet under the action of an electric field force, and then solidified by solvent evaporation (or melt cooling), so as to obtain nano-scale fiber patterns on the receiving medium a preparation technique. This pattern can form fiber structures with different diameters, different pattern structures, and the line width can be effectively controlled between tens of nanometers and tens of microns. The micro-nano structure formed by electrofluid jet printing has the advantages of smooth surface, good electrical conductivity and small line width. [0003] The most direct application of electrofluid...
