Abstract
The invention relates to a crucible platform lifting mechanism of a pseudo-single crystal silicon ingot furnace, which comprises a crucible platform, a graphite column, a steel column, a supporting plate, a lifting device, a flexible transmission shaft and a motor, wherein the graphite column is arranged on the bottom surface of the crucible platform, downwards extends out of a lower thermal insulator, and then is connected with the steel column; after downwards extending out of a furnace body, the steel column is fixedly connected with the supporting plate horizontally arranged; the lifting device is fixedly arranged below the furnace body, and is connected with the supporting plate; the flexible transmission shaft and the motor are arranged on the supporting plate; the lifting device is connected with and driven by the flexible transmission shaft; the flexible transmission shaft is connected with and driven by the motor. The crucible platform lifting mechanism has a reasonable structure, the crucible platform is enabled to move up and down in the thermal insulator of the ingot furnace, and the process requirement in the quasi-single crystal silicon ingot production process is met.
Description
Technical field
The invention belongs to accurate single-crystal ingot casting furnace technical field, particularly the hoisting appliance of crucible platform in ingot furnace.
Background technology
Accurate monocrystalline is the mode of casting crystalline that adopts on polycrystalline silicon ingot or purifying furnace, the quasi-monocrystalline silicon with high-conversion rate that a series of advanced persons' of process technical process is produced.Its main technique is that seed crystal is placed in the bottom by quartz crucible in accurate single crystal growing furnace, and under vacuum state, adopts accurately sectional temperature-controlledly, and while guaranteeing the thawing of silicon material, the seed crystal partial melting, grow monocrystalline thus.Domestic polycrystalline silicon ingot or purifying furnace is mainly the structure of GT at present, is that crucible, platform are motionless, and upper heating element, side heating element and upper thermal insulator move up and down.This structure can meet processing requirement to polycrystalline silicon ingot or purifying furnace, but just can not meet processing requirement in the ingot furnace of producing quasi-monocrystalline silicon.In order to meet the requirement of quasi-monocrystalline silicon ingot casting, ingot furnace must have strict thermograde and setting rate to control, and therefore the interface shape be applicable to needs an accurate fusing controlling organization of correspondence with it.
Summary of the invention
The object of the present invention is to provide a kind of hoisting appliance of crucible platform of accurate single-crystal ingot casting furnace, produce needed processing requirement to meet the quasi-monocrystalline silicon ingot casting.
For achieving the above object, the present invention adopts following scheme:
A kind of crucible platform hoisting appliance of accurate single-crystal ingot casting furnace, comprise crucible platform, graphite column, steel column, supporting plate, lifting device, transmission mechanism, motor.
Described crucible platform bottom surface is provided with the graphite column, and the graphite column stretches out lower thermal insulator downwards and with steel column, is connected outward, adopts the graphite column to be because the hot environment of thermal insulator inside; Steel column is fixedly connected with horizontally disposed supporting plate after stretching out body of heater downwards, is fixed with lifting device under body of heater, and lifting device is connected with supporting plate; Supporting plate is provided with transmission mechanism and motor, and lifting device is connected and driven by driving snake, and driving snake is connected and driven by motor.
During work, described driven by motor driving snake, driving snake become translational motion drive supporting plate to it by the high precision ball screw lifting device and move up and down, and supporting plate drives crucible platform by steel column and graphite column and realizes up-and-down movement.
The present invention is rational in infrastructure, and crucible platform can be moved up and down in ingot furnace, has met the quasi-monocrystalline silicon ingot casting and has produced needed processing requirement.
