Abstract

The invention provides a working voltage compensation method for near-field electro-hydrodynamic jet printing. The method comprises the following steps that initializing is carried out, and an expected voltage ve of near-field electro-hydrodynamic jet printing is set; and an actual voltage va of a high-voltage power supply of near-field electro-hydrodynamic jet printing equipment is acquired; an error voltage Delta v is calculated according to the expected voltage ve and the actual voltage va to obtain the Delta v through the formula of Delta v= ve-va; according to the expected voltage ve andthe error voltage Delta v, a working voltage compensation model of vc=ve+Delta v is constructed, and a reference voltage of the working voltage compensation model is vc; the reference voltage vc is sent to the high-voltage power supply of the jet printing equipment; the actual voltage va of the high-voltage power supply is acquired, and whether the acquired actual voltage va is equal to the expected voltage ve of jet printing is judged; and when the actual voltage va equal to the expected voltage ve, near-field electro-hydrodynamic pattern jet printing is carried out. The method has the beneficial effects that the voltage error of the near-field electro-hydrodynamic jet printing equipment is effectively controlled, so that the quality of a near-field electrohydrodynamic jet printing pattern is improved.

AI Technical Summary

Problems solved by technology

There is a certain error between the expected voltage and the actual voltage of the electrohydrodynamic jet printing equipment. Because the injection height of the near-field electrohydrodynamic jet printing is small, generally only a few millimeters or even smaller, compared with the traditional electrohydrodynamic jet printing technology The applied working voltage is also small, and this voltage error will have an impact on the quality of near-field electrohydrodynamic jet printing patterns
