A Multi-Physical Quantity Cooperative Control Method for Roll-to-roll EFI Printing Process

Abstract

The invention discloses a multi-physical-quantity cooperative control method oriented to a coil-to-coil electronic spraying printing process. The multi-physical-quantity cooperative control method oriented to the coil-to-coil electronic spraying printing process comprises the steps that (a) a series of process parameter reference values related to a base plate, a spraying nozzle and a spraying printing micro environment are input; (b) the position state and the jet flow state of the spraying nozzle, the accumulation state of liquid drops on the base plate, and the tension state and the position state of the base plate are respectively detected in real time; (c) the voltage of the spraying nozzle and the temperature and humidity of the spraying printing micro environment are commonly adjusted through a spraying printing micro environment-voltage mixing control method; (d) the tension and the position of the base plate and the position of the spraying nozzle are commonly adjusted through a tension-position mixing control method; (e) before spraying printing is finished, closed loop control is carried out on the parameters continuously until the whole electronic spraying printing process is finished. The multi-physical-quantity cooperative control method oriented to the coil-to-coil electronic spraying printing process obviously improves the electronic spraying printing quality, and has the advantages of adapting to various complex work conditions, not being interfered easily, being high in efficiency and reliability and the like, thereby being particularly suitable for a manufacturing process of coil-to-coil electronic spraying printing products.

Description

technical field [0001] The invention belongs to the technical field of electrojet printing, and more specifically relates to a multi-physical quantity cooperative control method for roll-to-roll electrojet printing process. Background technique [0002] The traditional printing technology mainly uses the principle of thermal bubbles or piezoelectricity to produce jetting, and the generation and ejection of droplet jetting depends on the size of the printing head, which is generally 1.89 times the diameter of the printing head. Manufacturing a small printing head requires Due to the complex micro-manufacturing process and materials, it is basically impossible to produce ultra-fine droplets by traditional jet printing technology. Compared with the traditional jet printing technology, the electrojet printing technology (electrohydrodynamic jet printing) that generates jets through an electrostatic field can produce smaller droplets and liquid filaments, and the diameter can rea...

Problems solved by technology

In contrast, in the prior art, the above-mentioned variables are often only controlled individually, or several of them are controlled at the same time without synergy between them, so it is difficult to meet the increasing requirements of EFI printing accuracy
