The invention discloses an automatic seed crystal shearing device of a single crystal furnace, which comprises a seed crystal shearing device (2) arranged at the lower part of an auxiliary chamber (1), the seed crystal shearing device (2) comprises a rotating motor (21), a rotating shaft (22) and a rotating bracket (23) which are connected in sequence, a telescopic cylinder (24) is fixed on the rotating bracket (23), and then the telescopic cylinder (24) is connected with a telescopic rack (25), a transmission gear (26) and an opening and closing gear (28) in sequence; the opening and closing gear (28) is coaxially connected with the transmission gear (26), a sliding rod (29) is arranged below the opening and closing gear (28), rack knife rests (210) are connected to the sliding rod (29) in a sliding mode, one end of each rack knife rest (210) is meshed with the opening and closing gear (28) on the corresponding side, and the other end of each rack knife rest (210) is connected with a cutting knife (211). The seed crystal shearing device has the advantages that automatic shearing of the seed crystal can be completed, working hours are saved, the risk that silicon slag generated when the seed crystal is sheared falls into the human face is effectively avoided, and safety is improved.
Description
technical field [0001] The invention relates to the technical field of photovoltaic manufacturing, in particular to an automatic seed crystal shearing device in a single crystal furnace. Background technique [0002] Usually, the furnace shell of a single crystal furnace consists of a main chamber and a secondary chamber. The structure of the secondary chamber is a circular cavity. The top of the secondary chamber is equipped with a rotating and lifting mechanism, which can complete the drawing of single crystal silicon rods. When pulling a single crystal silicon rod, according to the crystal pulling process, a fine crystal with a diameter of 5±0.5mm needs to be drawn first, and then the shoulder placement, shoulder turning, and equal diameter processes are carried out to achieve the size of the drawn crystal rod. When the drawn single crystal silicon rod is taken out of the furnace, it needs to be lifted to the sub-chamber first for storage, and then the sub-chamber is unsc...
