A WEIGHT MEASUERMENT DEVICE FOR A GROWING CRYSTAL OF CRYSTAL GROWTH FURMACE

摘要

The invention relates to a device for measuring a single crystal growth weight of a single crystal growth furnace. The device comprises a vertically pulling means; a sliding cantilever beam mounted on one side of the vertically pulling means to be moved upward and downward; a load cell mounted on a top surface of the sliding cantilever beam; a heating camber coupled to a lower part of the sliding cantilever beam; a driving unit coupled to an end part of the sliding cantilever beam; and a pulling bellows mounted on a lower part of a penetration unit formed in an upper surface of the heating chamber and an end part of the sliding cantilever beam; and a load cell bellows mounted between a lower surface of the driving unit and the top surface of the sliding cantilever beam.
