Embodiment Construction

[0023] As mentioned in the background technology, when the inkjet printing technology is used to print the film layer of the display in the prior art, the uniformity of the film layer is low, thereby reducing the display effect. The inventor found that the reason for this problem is that the ink spraying After being placed on the substrate, because the edge of the ink dries quickly, and the middle of the ink is thick, a film layer with a thick center and a thin edge is formed, and the film layer contains bubbles, which reduces the uniformity of the film layer and reduces the display. Effect.

[0024] Based on this, the present invention provides an inkjet print nozzle, by setting the helical blade inside the nozzle, when the inkjet printing device sprays ink, when the ink passes through the helical blade inside the nozzle, the bubbles in the ink will quickly rotate on the helical blade Movement, so that the air bubbles are fragmented and separated from the ink. When the ink is...

Abstract

The embodiment of the invention provides an ink-jet printing spray head which solves the technical problem that display effect is reduced as film layer uniformity is relatively low while an ink-jet printing technology is adopted to print a display film layer in the prior art. According to the ink-jet printing spray head provided by the embodiment of the invention, spiral blades are arranged insidea spray nozzle; when an ink-jet printing device sprays ink and ink passes through the spiral blades inside the spray nozzle, gas bubbles in the ink perform quick rotary motion on the spiral blades, so that the gas bubbles are fragmented and are separated from ink, and therefore, the gas bubbles escape, and number of the gas bubbles in ink sprayed onto a substrate base plate is reduced. The ink performs quick rotation motion on the spiral blades, and a guide device guides the ink, so that printing ink sprayed onto the substrate base plate forms cake-shaped ink which is thick in edge and is thin in middle, and automatic flattening of the ink is realized under action of surface tension of the ink; and after the ink is dried, uniform film layer thickness can be reached, so that uniformity ofthe film layer is improved.

Description

technical field [0001] The invention relates to the technical field of printing machines, in particular to an inkjet print head. Background technique [0002] Inkjet printing is a film-forming method that prints ink of functional materials on corresponding positions under the precise control of a computer, and converts digital graphics into patterns. In the display industry, inkjet printing technology can be used to print the printed area of ​​the substrate to form the target film layer. However, when the inkjet printing technology is used to print the film layer in the display, the uniformity of the film layer is low, thereby reducing the display effect. Contents of the invention [0003] In view of this, the embodiment of the present invention provides an inkjet printing nozzle, which solves the problem that the uniformity of the film layer is low when the inkjet printing technology is used to print the film layer of the display in the prior art, thereby reducing the di...
