Problems solved by technology

Although these solutions are real-time sampling, they cannot be analyzed and observed in real time. It is necessary to analyze the printing results after printing and compare them with the printing parameters. This not only reduces the printing efficiency to a certain extent, but also makes it difficult to find errors during the printing Defects are corrected in a timely manner

Abstract

The invention belongs to the field of printing electronic technique, and relates to a real-time monitoring optical path system for micro-nano structure appearance in ink-jet printing. A light beam sent by a laser device is subjected to light beam energy regulation through an attenuator, the light beam passes through a printing sample and then orderly passes through a first convex lens and a secondconvex lens, light finally is converged at a CCD camera, the CCD camera is connected with an external computer, a printing structure on the printing sample can be observed in real time through the computer, and according to difference of focal length of the selected convex lens, a result observed through the computer is an scaled image of the printing structure. The system has a simple and visualoptical path, convenient and adjustable elements and reliable principles, is convenient and simple to operate, is easy to realize, and can be widely applied to various micro-nano structures based onan ink-jet printing technology, and the electronic manufacturing field.

Description

Technical field: [0001] The invention belongs to the technical field of printed electronics, and relates to a real-time monitoring system for inkjet printing, in particular to an optical path system for real-time monitoring of micro-nano structure morphology in inkjet printing. Background technique: [0002] Inkjet printing technology (Inkjet Printing) is a "direct writing" printed electronic technology, under the precise control of the computer, it uses gas pressure, electric field force or other forms of force to spray functional oil film onto the surface of various substrates drop by drop , to obtain a specific micro-nano structure or thin film. This technology has the advantages of low cost, environmental friendliness, high efficiency and direct writing. It has been widely used in the field of new electronic materials in recent years. According to different inkjet methods, inkjet printing can be divided into two types: continuous inkjet printing (using electric field dri...
