(KO) 액적분사장치 및 방법
Abstract:
(EN) The present invention relates to a liquid droplet spraying apparatus and method. The liquid droplet spraying apparatus of the present invention comprises: a chamber containing a fluid; a nozzle body having a nozzle for spraying the fluid in the chamber to one side of a material to be printed; an electrostatic spray module which is arranged in the vicinity of the chamber or the nozzle, and which forms an electrostatic field for the fluid contained in the chamber to provide a first spray force for spraying the fluid via the nozzle to form a liquid droplet; a physical spray module which is arranged in the chamber and opposite the nozzle, and which provides second spray force for assisting the first spray force when the first spray force is generated; and a control unit for controlling the electrostatic spray module and the physical spray module such that the first spray force and the second spray force can be provided in a specific pattern. The liquid droplet spraying method of the present invention comprises the steps of forming an electrostatic field for the fluid contained in the chamber using the electrostatic spray module arranged in the vicinity of the chamber or the nozzle to provide a first spray force for spraying the fluid via the nozzle to form a liquid droplet, and providing a second spray force for assisting the first spray force using the physical spray module arranged in the chamber and opposite the nozzle, thus spraying the fluid and forming a liquid droplet.
(FR) La présente invention porte sur un appareil et un procédé de pulvérisation de gouttelettes de liquide. L'appareil de pulvérisation de gouttelettes de liquide selon la présente invention comprend : une chambre contenant un liquide ; un corps de buse comportant une buse pour pulvériser le liquide dans la chambre sur un côté d'un matériau devant être imprimé ; un module de pulvérisation électrostatique qui est disposé au voisinage de la chambre ou de la buse, et qui forme un champ électrostatique pour le liquide contenu dans la chambre afin de fournir une première force de pulvérisation pour pulvériser le liquide par l'intermédiaire de la buse afin de former une gouttelette de liquide ; un module de pulvérisation physique qui est disposé dans la chambre et à l'opposé de la buse, et qui fournit une deuxième force de pulvérisation pour assister la première force de pulvérisation lorsque la première force de pulvérisation est générée ; et une unité de commande pour commander le module de pulvérisation électrostatique et le module de pulvérisation physique de telle sorte que la première force de pulvérisation et la deuxième force de pulvérisation peuvent être fournies selon un motif spécifique. Le procédé de pulvérisation de gouttelettes de liquide selon la présente invention comprend les étapes consistant à former un champ électrostatique pour le liquide contenu dans la chambre à l'aide du module de pulvérisation électrostatique disposé au voisinage de la chambre ou de la buse afin de fournir une première force de pulvérisation pour pulvériser le liquide par l'intermédiaire de la buse afin de former une gouttelette de liquide, et à fournir une deuxième force de pulvérisation pour assister la première force de pulvérisation à l'aide du module de pulvérisation physique disposé dans la chambre et à l'opposé de la buse, permettant ainsi de pulvériser le liquide et de former une gouttelette liquide.
