A nano-electrostatic printing device in a high-precision and controllable micro-environment

Abstract

The invention discloses a nanometer electrostatic spray printing device under a high-precision controllable microenvironment. The device mainly comprises a refrigeration heater, an air supply pipe, a microenvironment control cavity, a temperature / humidity sensor, a voltage source, a nanometer electrostatic spray printing device, an image acquirer, a light source controller, a moving platform controller, an arbitrary function signal generator, a high-voltage amplifier, a high-precision adjustable microflow pump control panel, a display and an industrial personal computer. The refrigeration heater, the air supply pipe and the microenvironment control cavity are used for forming a microenvironment with uniform temperature / humidity distribution, wherein the high-precision adjustable microflow pump control panel is used for adjusting a polymer solution flow. The influence on the spray printing process by the environment factors of the nanometer electrostatic spray printing device is largely reduced; and three important influence factors of substrate moving speed, solution flowing speed and electrostatic field voltage in nanometer electrostatic spray printing are integrated, and are converted to measurable and controllable physical quantities to output to the industrial personal computer for processing to form a closed-loop control system.
