AI Technical Summary

Technical Problem

Existing vacuum processing systems face challenges in maintaining continuous processing without interruptions during material feeding or output operations, as the vacuum level is disrupted when these operations are performed.

Method used

A vacuum processing device with multiple chambers and internal valves that maintain a higher vacuum level in the processing chamber during material feeding and output, allowing continuous processing by isolating the processing chamber from the feed and outlet chambers using asynchronous valve controls.

Benefits of technology

Ensures uninterrupted vacuum processing by maintaining the required vacuum level in the processing chamber during material handling, enabling continuous operation without interruptions.

Abstract

Vacuum Processing Device A vacuum processing device is provided which is configured to have multiple chambers such as a processing chamber (20), a feed chamber (10) and an outlet chamber (30), wherein when the first and second internal valves (42, 43) located between the chambers are closed, the vacuum degree in the processing chamber (20) is higher than that in the feed chamber (10) and the first outlet chamber (30), so that material feeding and output can be performed through the feed chamber (10) and the outlet chamber (30). Since, at the same time, the vacuum degree in the processing chamber (20) always remains in the state required for processing, the vacuum processing process can continue during the feeding or output operation to ensure continuous processing without interruption in the vacuum process.
