Polycrystalline silicon crystal bar overturning frame

Abstract

The invention discloses a polycrystalline silicon crystal bar overturning frame and relates to the technical field of mechanical equipment. The polycrystalline silicon crystal bar overturning frame comprises a vertical pillar, wherein a cross rod is arranged at the upper end of the vertical pillar; an overturning mechanism is arranged on the cross rod and comprises a suspended lifting plate; the lifting plate is arranged along a horizontal direction; support plates are arranged at the lower end of the lifting plate; a rotating shaft penetrates through each support plate and is arranged along the horizontal direction; a rotating wheel used for driving the rotating shaft to rotate is fixedly arranged at one end of each rotating shaft; at least two driving wheels are fixedly arranged on eachrotating shaft; annular belts are sleeved on the driving wheels. Through the polycrystalline silicon crystal bar overturning frame, operators cannot touch the crystal bars in the whole process of overturning the polycrystalline silicon crystal bars; the pollution is avoided; meanwhile, the operation is convenient and easy; the damage of corners and edges and the shifting of the crystal bars causedby manually overturning the crystal bars can be avoided; the quality of the polycrystalline silicon crystal bars is ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a polysilicon ingot turning frame. Background technique [0002] Polysilicon is a form of elemental silicon. When the molten elemental silicon solidifies under supercooling conditions, the silicon atoms are arranged into many crystal nuclei in the form of diamond lattice. If these crystal nuclei grow into crystal grains with different crystal plane orientations, these crystal grains combine to crystallize into polycrystalline silicon. . Polysilicon is the direct raw material for the production of monocrystalline silicon, and is the basic electronic information material for semiconductor devices such as contemporary artificial intelligence, automatic control, information processing, and photoelectric conversion. Known as "the cornerstone of the microelectronics building". [0003] When the polycrystalline silicon ingot is actually used, it needs to be cut and cut i...

AI Technical Summary

Problems solved by technology

Due to the requirements of the polysilicon crystal ingot cutting process, the polysilicon crystal ingot needs to be turned over during the cutting process. Since the polysilicon crystal support weighs 200kg, it is too difficult to manually turn over, which is easy to cause chipping and displacement of the ingot, and When manually turning over, due to the touch of the ingot, it will cause pollution and affect the quality of polysilicon
