Abstract
The long crystalline substance of sapphire single-crystal crystal relates to the long crystalline substance vacuum oven of a kind of sapphire single-crystal crystal with vacuum oven.While being mainly the monocrystalline sapphire section for solving the production of the long crystalline substance of existing sapphire single-crystal crystal vacuum oven, wasting large problem designs.It comprises body of heater, on body of heater, there is large bell, electrode is contained on large bell, on large bell, there is small furnace cover, single crystal pulling mechanism is contained on fixed leg, fixed leg is fixed on basis, ground, below single crystal pulling mechanism, there is single crystal pulling bar, crucible in body of heater is placed on crucible pallet, crucible pallet is placed on pallet fore-set, pallet fore-set stands on furnace bottom, there is crucible cover crucible top, above crucible cover, there is upper thermoscreen, there is heating element crucible outside, heating element is connected with the electrode on large bell, below heating element, there are lower thermoscreen and side thermoscreen with surrounding, described crucible, heating element, side thermoscreen is oval offset flat shape.Advantage is to produce the sapphire monocrystal of oval offset flat shape, less wastage when section.
Description
Technical field:
The utility model relates to the long crystalline substance vacuum oven of a kind of sapphire single-crystal crystal.
Background technology:
The method that artificial production diameter exceedes the above large size of 100mm, optical grade sapphire single-crystal at present mainly comprises crystal pulling method, kyropoulos, heat-exchanging method, the crystal shape that these methods are grown mostly is cylindrical, pyriform, when user uses, need as requested crystal blank be cut into various specification.
Along with scientific and technical development, dual-use market is increasing to the dimensional requirement of sapphire single-crystal, and the size of for example some infrared window piece has exceeded 400mm, even if civilian LED substrate slice is also towards 8-12 inch future development.If adopt the equipment of above-mentioned traditional crystal pulling method, kyropoulos and heat-exchanging method growing sapphire monocrystalline, in order to obtain enough large sapphire single-crystal window or substrate slice, must on three-dimensional space, strengthen equipment size, then brilliant base cutting is obtained to diaphragm, substrate slice or other shaped member of dimension, in the brilliant base process of processing, due to needs will and irregular cylindrical (or pyriform) brilliant base be processed into regular plate-shaped member, therefore can produce a large amount of losses.
As fully visible, in order to obtain larger sized diaphragm or substrate slice, really need on three-dimensional space, add the size of macrocrystal simultaneously, this not only causes the increase of equipment cost, and in crystal growing process, need to consume more electric energy and complete the growth of crystal, in the crystal course of processing, also can produce very large spillage of material, so loss and waste is large simultaneously.
Summary of the invention:
Technical problem to be solved in the utility model is to provide a kind of in the time that monocrystalline sapphire is cut into slices, and the volume of throwing away part is little, less wastage, the long crystalline substance vacuum oven of sapphire single-crystal crystal that sapphire utilization ratio is high.
Above-mentioned purpose is achieved in that it comprises the body of heater that is provided with vacuum interface, on body of heater, there is large bell, electrode is contained on large bell, on large bell, small furnace cover is housed, single crystal pulling mechanism is contained on fixed leg, fixed leg is fixed on basis, ground, single crystal pulling bar is housed below single crystal pulling mechanism, in body of heater, there is crucible, crucible is placed on crucible pallet, crucible pallet is placed on pallet fore-set, pallet fore-set stands on furnace bottom, there is crucible cover the top of crucible, above crucible cover, there is upper thermoscreen, there is heating element the outside of crucible, heating element is connected with the electrode on large bell, below heating element, there are lower thermoscreen and side thermoscreen with surrounding, it is characterized in that: described crucible, heating element, side thermoscreen is oval offset flat shape.
The utility model has the advantages that: because the long crystalline substance of sapphire single-crystal crystal crucible, heating element, the side thermoscreen of vacuum oven are oval offset flat shape, so can produce the sapphire monocrystal of oval offset flat shape.With respect to current cylindrical or pyriform crystal, the crystal of this form electric energy consuming of growing can reduce approximately 30%, and while cutting onesize diaphragm with the sapphire monocrystal of this shape, processing loss reduces approximately 50% than existing cylindrical or pyriform sapphire crystal.
Brief description of the drawings:
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
When Fig. 3 is oval flats sapphire single-crystal crystal and existing cylindrical sapphire single-crystal crystal-cut, the how many contrast of waste part.
Embodiment:
With reference to Fig. 1, 2, it comprises the body of heater 6 that is provided with vacuum interface 15, on body of heater, there is large bell 5, electrode 4 is contained on large bell, on large bell, small furnace cover 3 is housed, single crystal pulling mechanism 1 is contained on fixed leg 13, fixed leg is fixed on basis, ground, single crystal pulling bar 2 is housed below single crystal pulling mechanism, in body of heater, there is crucible 9, crucible is placed on crucible pallet 10, crucible pallet is placed on pallet fore-set 12, pallet fore-set stands on furnace bottom, there is crucible cover 16 top of crucible, above crucible cover, there is upper thermoscreen 14, there is heating element 8 outside of crucible, heating element is connected with the electrode on large bell, below heating element, there are lower thermoscreen 11 and side thermoscreen 7 with surrounding, it is characterized in that: described crucible, heating element, side thermoscreen is oval offset flat shape.
Clearer for what problem was said, we show by accompanying drawing 3, in figure, A is the oval offset flat shape sapphire single-crystal crystal of producing with the utility model, B is existing cylindrical sapphire single-crystal crystal, C is the sapphire single-crystal crystal diaphragm that cutting obtains, the part that the oval offset flat shape sapphire single-crystal crystal that D produces with the utility model while being cutting and existing cylindrical sapphire single-crystal crystal all will be thrown away, E is the part that existing cylindrical sapphire single-crystal crystal is thrown away than the oval offset flat shape sapphire single-crystal crystal of producing with the utility model more.From exploded view Fig. 3, can find out, the oval type offset flat shape sapphire single-crystal crystal-cut of producing with the utility model is made sapphire single-crystal crystal cut can save a large amount of sapphire single-crystal crystal, and can improve working (machining) efficiency; Because sapphire single-crystal crystal is expensive especially, for the production of the starting material of sapphire single-crystal crystal because its purity requirement is high especially, not only in great shortage but also expensive, so the utility model in having solved the habitual mode of people's long-term production, the saving that has brought huge economic benefit and resource, human and material resources.
