Abstract
The present invention discloses a multi-scraper structure. A plurality of scrapers is used in a cleaning panel process for repeatedly scraping the remnant contaminants on the surface of the panel. Moreover, a pressure control unit is used for immediately modifying the output pressure applied to a second scraper according to the resistance encountered by a first scraper.
