Vertical type single-rod squaring machine for monocrystalline silicon

Abstract

The invention discloses a vertical type single-rod squaring machine for monocrystalline silicon. The vertical type single-rod squaring machine for monocrystalline silicon comprises a cutting chamber, a wiring chamber, a feeding and discharging device and an electrical chamber. The cutting chamber comprises a cutting head for cutting a single silicon rod and further comprises a silicon rod supporting seat for supporting the lower end of the single silicon rod and a silicon rod compressing mechanism for compressing and fixing the upper end of the silicon rod. The silicon rod compressing mechanism comprises a compressing support, an extension rod fixed to the compressing support, and a compressing seat fixed to the extension rod and used for being connected with the silicon rod. The extension rod is provided with an open groove through which a wire mesh of the cutting head can penetrate. The vertical type single-rod squaring machine for monocrystalline silicon achieves the efficient machining effects of achieving vertical type cutting, avoiding gluing, not shearing the wire mesh, automatically aligning crystal lines, achieving automatic feeding and discharging and simultaneously cutting four sides, is simple in process, convenient to operate and low in machining cost, achieves automation easily and meets the requirement for equipment of users.

Description

technical field [0001] The invention relates to the technical field of crystalline silicon cutting, in particular to a vertical single-rod squarer for monocrystalline silicon. Background technique [0002] The method of making single crystal silicon is usually to make polycrystalline silicon or amorphous silicon first, and then use Czochralski method or suspension zone melting method to grow rod-shaped single crystal silicon from the melt. When the molten elemental silicon is solidified, the silicon atoms are arranged in the diamond lattice to form many crystal nuclei. If these crystal nuclei grow into grains with the same crystal plane orientation, these grains combine in parallel to crystallize into single crystal silicon. Monocrystalline silicon, also known as silicon single crystal, is the most basic material in electronic information materials and photovoltaic industries, and belongs to the category of semiconductor materials. Monocrystalline silicon has penetrated int...
