Title:
INKJET PRINTING DEVICE CAPABLE OF CONTROLLING TRANSPORT LIQUID TO PRINT PATTERNED SURFACE AND PRINTING METHOD
Document Type and Number:
WIPO Patent Application WO/2019/119928
Kind Code:
A1
Abstract:
An inkjet printing device capable of controlling a transport liquid to print a patterned surface, comprising an ink cartridge circuit board (1) containing m rows of ink discharge hole clusters, and m rows of corresponding brush holders (2) fixed to a lower portion of the ink cartridge circuit board. Each row of ink discharge hole clusters contains n ink-discharge holes (5). Correspondingly, each row of brush holders contains n sets of fixing holes (3). A plurality of conical fibers (hairpins) (4) is inserted and fixed inside each fixing hole. The conical fibers have a micro or nano structure on a surface thereof, and form a set of conical fiber array units (brush hairs), such that the bottom of each ink discharge hole corresponds to a set of brush hairs, and a vertical projection of the ink discharge hole corresponds to the tip position of the brush hair. The tip of the brush hairs point downward and form an angle of 12-18° with a horizontal plane. The conical fiber material used in the application is affordable and accessible, and the inkjet printing technology can dispense ink at an accurate position. The fine structure of the conical fibers allows ink to be transported in a controllable, continuous and uniform manner, thereby resolving issues with uniformity present in many film formation techniques.
