Vacuum exposure device for exposure machine

Abstract

The invention discloses a vacuum exposure device for an exposure machine. The vacuum exposure device is used for exposure platemaking of a screen (13) and comprises an exposure lamp (6) and a vacuum suction system (7); the vacuum exposure device for the exposure machine also comprises an upper sealing component (1) and a lower sealing component (2) which are arranged below the exposure lamp (6), wherein an airtight space (3) is formed between the upper sealing component (1) and the lower sealing component (2); the vacuum suction system (7) can vacuumize the space (3); a moving part (4) for putting the screen (13) is arranged on the lower sealing component (2); the upper sealing component (1) comprises a glass plate (5); when the vacuum suction system (7) vacuumizes the space (3), the moving part (4) moves upwards and drives up the screen (13) to be laminated with the glass plate (5). The vacuum exposure device for the exposure machine, disclosed by the invention, has the advantages that the state of the screen can be monitored in real time, so that the reliability of the exposure platemaking is better ensured.

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.
