Devices for automatic cleaning of a monocrystalline silicon bar

Abstract

Provided are automatic cleaning devices for a monocrystalline silicon bar, which include a base frame, a sprayer, a scrubber, and an air-jetter. Bottom of an inner side of the base frame is configured to place a monocrystalline silicon bar. A plurality of groups of the sprayers, a plurality of groups of the scrubbers, and a plurality of groups of the air-jetters are all disposed on side walls and a top surface of the base frame whose bottom of an inner side is removed. The sprayer is configured to spray the monocrystalline silicon bar. The scrubber is configured to scrub the monocrystalline silicon bar. The air-jetter is configured to purge the monocrystalline silicon bar.
