Abstract

The invention relates to the technical field of displaying, and discloses a vacuum drying oven. The vacuum drying oven is used for drying an ink-jet printing device. The vacuum drying oven comprises acavity, a hot plate, a solvent trough and a cold plate, wherein an exhaust port is formed in the top of the cavity, the hot plate is arranged in the cavity, a bearing face used for placing the ink-jet printing device is formed on the surface, facing the exhaust port, of the hot plate, the solvent trough is arranged on the periphery of the hot plate, the temperature of the solvent trough can be independently controlled, solvent trough openings used for diffusing a solvent are formed in the surface of the side, facing the exhaust port, of the solvent trough, and the cold plate is arranged in the cavity and located between the hot plate and the exhaust port. According to the vacuum drying oven, parts on the surface of the ink-jet printing device are evenly dried by creating the same atmosphere on the surface of the ink-jet printing device which is placed in the vacuum drying oven.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a vacuum drying oven. Background technique [0002] In the process of making the inkjet printing device, the surface of the inkjet printing device needs to be dried. The speed of solvent volatilization is different, especially there is a significant difference in the speed of solvent volatilization between the middle part and the edge part of the inkjet printing device, which leads to the uneven display of the surface of the inkjet printing device after drying, which affects the quality of the inkjet printing device. use. Contents of the invention [0003] The present invention provides a vacuum drying oven. The vacuum drying oven makes each part of the surface of the ink-jet printing device dry evenly by creating the same atmosphere on the surface of the ink-jet printing device placed therein. [0004] To achieve the above object, the present invention provides the followin...
