Abstract
(EN)
The present invention relates to an apparatus for feeding a new chemical liquid to a chemical liquid container for containing a chemical liquid used in an inkjet printer for manufacturing a display and, more specifically, to a chemical liquid feeding apparatus which feeds an inert gas into a chemical liquid feeding chamber so that the oxygen concentration and humidity in the chemical liquid feeding chamber are controlled. An embodiment of the chemical liquid feeding apparatus of the present invention is an apparatus for feeding a chemical liquid into a chemical liquid container for containing a chemical liquid used in an inkjet printer for manufacturing a display, the apparatus comprising: a chemical liquid feeding chamber having an inert gas inlet through which an inert gas is introduced, and an outlet through which an internal gas is discharged; an inert gas feeding means for feeding an inert gas to the inert gas inlet; a means for opening/closing a cap of the chemical liquid container which is provided in the chemical liquid feeding chamber and opens/closes the cap of the chemical liquid container; and a chemical liquid feeding means for feeding a chemical liquid into the chemical liquid container. Due to the inert gas fed into the chemical liquid feeding chamber, the oxygen concentration inside the chemical liquid feeding chamber is reduced to a preset concentration or less.

La présente invention concerne un appareil pour alimenter un nouveau liquide chimique dans un récipient de liquide chimique pour contenir un liquide chimique utilisé dans une imprimante à jet d'encre pour fabriquer un dispositif d'affichage et, plus spécifiquement, à un appareil d'alimentation en liquide chimique qui introduit un gaz inerte dans une chambre d'alimentation en liquide chimique de telle sorte que la concentration en oxygène et l'humidité dans la chambre d'alimentation en liquide chimique sont commandées. Un mode de réalisation de l'appareil d'alimentation en liquide chimique de la présente invention est un appareil pour introduire un liquide chimique dans un récipient de liquide chimique pour contenir un liquide chimique utilisé dans une imprimante à jet d'encre pour fabriquer un dispositif d'affichage, l'appareil comprenant : une chambre d'alimentation en liquide chimique ayant une entrée de gaz inerte à travers laquelle un gaz inerte est introduit, et une sortie à travers laquelle un gaz interne est évacué ; un moyen d'alimentation en gaz inerte pour introduire un gaz inerte dans l'entrée de gaz inerte ; un moyen pour ouvrir/fermer un capuchon du récipient de liquide chimique qui est disposé dans la chambre d'alimentation en liquide chimique et ouvre/ferme le capuchon du récipient de liquide chimique ; et un moyen d'alimentation en liquide chimique pour introduire un liquide chimique dans le récipient de liquide chimique. Du fait du gaz inerte introduit dans la chambre d'alimentation en liquide chimique, la concentration en oxygène à l'intérieur de la chambre d'alimentation en liquide chimique est réduite à une concentration prédéfinie au maximum.
