Ink piezoelectric control system and ink piezoelectric control optimization method capable of improving printing precision

Abstract

The invention discloses an ink piezoelectric control system and ink piezoelectric control optimization method capable of improving printing precision. The system controls a piezoelectric driving module through an upper computer to drive a nozzle to jet ink droplets; meanwhile, an ink droplet monitoring system continuously collects a plurality of images in the falling process of the ink droplets, carries out image comparison and analysis, judges whether satellite droplets are generated or not, and transmits a data result to the upper computer; and the upper computer analyzes the data result, controls a temperature regulation and control system to automatically regulate the temperature of the piezoelectric nozzle, and feeds back a real-time temperature value to the upper computer, so as to eliminate generation of the satellite droplets. The system is not limited by printing ink types, is wide in application range and high in automation degree, can automatically eliminate the satellite droplets generated by ink temperature setting errors, nozzle wear, nozzle surface aging and the like without human interference, and provides guarantee for ultrahigh-precision graphical ink-jet printing which is high in quality and free of a stray satellite point.
