Vacuum exposure device for exposure machine

Abstract

The invention discloses a vacuum exposure device of an exposure machine, which is used for exposing and making a screen plate (13), comprising an exposure lamp (6) and a vacuum suction system (7), and the vacuum exposure device of the exposure machine also includes An upper sealing assembly (1) and a lower sealing assembly (2) arranged below the exposure lamp (6), forming a closed space (3) between the upper sealing assembly (1) and the lower sealing assembly (2) , the vacuum suction system (7) can evacuate the space (3), the lower sealing assembly (2) is provided with a movable part (4) for placing the screen (13), the upper sealing The assembly (1) includes a glass plate (5), and when the vacuum suction system (7) vacuumizes the space (3), the movable part (4) moves upward, driving the screen plate (13) upward Bond with the glass plate (5). The present invention can monitor the state of the screen plate intuitively in real time, and better guarantees the reliability of exposure plate making.

Description

technical field [0001] The invention relates to a vacuum exposure device of an exposure machine. Background technique [0002] At present, in the plate-making industry, traditional exposure machines generally adopt the exposure method of the lower light source, from top to bottom, there are rubber skins, screen plates, glass and exposure lamps. When exposing, place the screen plate upside down on the exposure machine glass, and use vacuum suction to make the rubber cover and glass close together, thereby pressing the screen plate to fit tightly with the glass. Because the rubber is opaque, people cannot see the status and changes of the screen during exposure during actual use, and cannot intuitively monitor the quality of exposure; There are a lot of electrical components, and the water circulation pipeline and water storage tank of the water-cooled exposure lamp take up a lot of space, and the lamp tube should not be too close to the water storage tank. When the exposure ...

AI Technical Summary

Problems solved by technology

Because the rubber is opaque, people cannot see the status and changes of the screen during exposure during actual use, and cannot intuitively monitor the quality of exposure; There are a lot of electrical components, and the water circulation pipeline and water storage tank of the water-cooled exposure lamp take up a lot of space, and the lamp tube should not be too close to the water storage tank. When the exposure lamp is working, heat will be generated to form water vapor, which will affect the humidity and exposure effect

Therefore, the exposure machine with a lower light source is more suitable for using an air-cooled exposure lamp, rather than a water-cooled exposure lamp with higher efficiency and better cooling effect.
