1. A device for automatic cleaning of a monocrystalline silicon bar, configured to clean the monocrystalline silicon bar before slicing, and comprising a base frame, a plurality of groups of sprayers, a plurality of groups of scrubbers, a plurality of groups of air-jetters, and a blade,
wherein a bottom of an inner side of the base frame is configured to hold the monocrystalline silicon bar;
the sprayers, the scrubbers and the air-jetters are disposed on side walls of the base frame except the bottom of the inner side or on a top surface of the base frame;
the sprayers are configured to spray the monocrystalline silicon bar;
the scrubbers are configured to scrub the monocrystalline silicon bar;
the air-jetters are configured to purge the monocrystalline silicon bar; and
the blade is disposed at an end of an inner side wall of the base frame near the bottom in a long side direction for removing glue particles on a material holder on which the monocrystalline silicon bar is placed.
