Problems solved by technology

[0003] In actual use, when the ink of the OLED printer is used up, the ink bottle needs to be replaced. At this time, the inkjet head of the OLED printer is easy to enter the air. When the OLED printer is restarted, it will affect the inkjet effect at the beginning of the startup, resulting in Defective product; In addition, the inkjet head of OLED printers is sometimes blocked and unable to eject ink effectively (for example, it is blocked by undissolved solute particles in the ink). When this happens, it is generally cleaned manually. inconvenient

Abstract

The invention belongs to the technical field of printers, and discloses an OLED printer nozzle exhaust device and a control method thereof. The OLED printer nozzle exhaust device includes: a vacuum ink suction head, which is arranged upwardly on the lower side of the inkjet head of the OLED printer, and its upper end There is a gap between the inkjet head and the vacuum generating device, which is connected to the vacuum ink suction head through the ink suction pipe, and is used to provide vacuum negative pressure for the vacuum ink suction head; the ink drop observer includes observation devices respectively arranged on both sides of the gap A light source and an observation camera, the observation camera is used to take images of ink droplets passing through the gap, and the observation light source is used to provide the background light required for the work of the observation camera; the controller is electrically connected to the vacuum generating device and the ink drop observer; The computer is used to control the work of the vacuum generating device and the ink drop observer through the controller; it can realize the air discharge in the inkjet head and the automatic cleaning of the inkjet head.

Description

technical field [0001] The invention relates to the technical field of printers, in particular to an OLED printer nozzle exhaust device and a control method thereof. Background technique [0002] OLED (Organic Light-Emitting Diode) printer is a device used to prepare organic light-emitting layers on OLED substrates. It mainly uses high-precision nozzles to print materials directly on the surface of the substrates to form RGB organic light-emitting layers. It is a type of inkjet printer. . [0003] In actual use, when the ink of the OLED printer is used up, the ink bottle needs to be replaced. At this time, the inkjet head of the OLED printer is easy to enter the air. When the OLED printer is restarted, it will affect the inkjet effect at the beginning of the startup, resulting in Defective product; In addition, the inkjet head of OLED printers is sometimes blocked and unable to eject ink effectively (for example, it is blocked by undissolved solute particles in the ink).
