Abstract

The invention belongs to the technical field of ink-jet printing visual detection, and discloses an ink-liquid cone detection device suitable for ink-jet printing. The ink-liquid cone detection devicecomprises a jet module, a motion module, a mechanical auxiliary module and a vision observation module, wherein the mechanical auxiliary module comprises a machine frame, a vertical fine adjustment mechanism and an inclined fine adjustment mechanism; and the visual observation module comprises a camera and a light source which are obliquely arranged, and a mirror symmetry image is acquired through reflection of a substrate. The invention further discloses a corresponding detection method. The detection method is used for achieving optimization schemes which comprise the nozzle position, inclination angle, nozzle and substrate distance detection, the ink liquid cone size and the contour change detection, the jet flow appearance and spraying angle detection, the lag time and duration detection of the jet flow relative to the injection signal, the spraying process parameter feedback control and the drop point position deviation of the jet flow on the moving substrate. According to the device and the method, an ink-liquid cone body and a nozzle for ink-jet printing are executed in a high-efficiency and high-precision mode, and on-line detection is carried out on the jet flow.

Description

technical field

[0001] The invention belongs to the technical field of inkjet printing visual detection, and more particularly relates to an ink cone detection device and method suitable for inkjet printing. Background technique

[0002] Inkjet printing technology is being used in the manufacture of display screens, flexible sensors and other fields. Compared with traditional evaporation technology, it has the advantages of simple process, high printing resolution and less material waste. Ink cones are generally produced during inkjet printing. Common inkjet printing technologies include piezoelectric jet printing technology and electrofluid jet printing technology. Piezoelectric jet printing technology deforms piezoelectric ceramics under the action of voltage to The ink is extruded from the ink cavity and forms a meniscus, and the electrofluid printing technology pulls the ink out through a high-voltage electric field to form a Taylor cone at the tip of the nozzle. In act...
