Description
Technical field
The utility model relates to kyropoulos sapphire crystal and manufactures field, particularly relates to the accurate weighing system that brilliant equipment grown automatically by a kind of kyropoulos sapphire, is applicable to other similar field simultaneously.
Background technology
It is very wide that optics due to sapphire crystal penetrates band, all has good light transmission from near-ultraviolet light (190nm) to middle infrared (Mid-IR), is therefore used in a large number on optical element, infrared facility, high intensity laser beam lens materials and mask material.Current super brightness is white/and the quality of blue-ray LED depends on the material quality of epitaxy of gallium nitride (GaN), and the sapphire substrate surface working quality of epitaxy of gallium nitride quality then with used is closely bound up, sapphire (monocrystalline Al
2o
3) lattice constant mismatch rate between the race's deposit film of C face III-V and II-VI is little, meet resistant to elevated temperatures requirement in GaN epitaxy technique simultaneously, make sapphire wafer become the critical material making white/indigo plant/green light LED.
The technology of at present the most ripe growing large-size low-stress zero defect sapphire crystal still or kyropoulos.Kyropoulos sapphire crystallization furnace development comparative maturity, slave unit structure all develops complete to control method, but also there is crystal weight measures inaccurate drawback, and its source of error is just the airtight construction of the opening of bell.What go up the airtight of the opening of bell at present is bellows structure.Namely bellows structure can ensure airtight reliability, can stretch up and down again in the seed rod process that moves up and down thereupon, is therefore the frame mode that current long brilliant stove generally adopts.But due to stretching up and down of corrugated tube, causing the change of drawing force, bringing error to weighing.
Summary of the invention
(1) technical problem that will solve
This patent main purpose is to provide a kind of kyropoulos sapphire automatically to grow the accurate weighing system of brilliant equipment, removes the error in crystals weighed link.
(2) technical scheme
For achieving the above object, this patent provides a kind of kyropoulos sapphire automatically to grow the accurate weighing system of brilliant equipment, comprise the burner hearth for arranging thermal field and crucible, described roof of the furnace arranges the upper bell of sealing, the center of described upper bell arranges bell mouth, described upper bell mouth arranges magnetic fluid, the internal diameter of described magnetic fluid arranges identical with the internal diameter of described upper bell mouth, described magnetic fluid is fixed by flange and described upper bell mouth, arranging seed rod through described magnetic fluid and upper bell mouth stretches into described burner hearth, described seed rod end arranges seed chuck, described seed rod arranges belt pulley, described belt pulley is connected with brilliant rotating motor by belt, the Jing Sheng mechanism that can move up and down is set, described Jing Sheng mechanism arranges through hole, the LOAD CELLS of at least two is arranged symmetrically with around described through hole, described seed rod is arranged in described LOAD CELLS, and through described through hole.
Described crystalline substance rises the brilliant lifting motor of organization establishes and crystalline substance rises screw mandrel, and the crystalline substance described in described brilliant lifting motor drives rises screw mandrel and rotates, thus the Jing Sheng mechanism lifting described in driving.
(3) beneficial effect
As can be seen from technique scheme, this patent has following beneficial effect:
1, burner hearth and extraneous vacuum-sealing is realized;
2, allow seed rod to move up and down, and do not increase crystals weighed error.
Accompanying drawing explanation
Fig. 1 is the structural representation that the accurate weighing system of brilliant equipment grown automatically by kyropoulos sapphire.
Embodiment
Below in conjunction with concrete embodiment, the utility model is further expanded description, but it is pointed out that the utility model structure required for protection is not limited to the concrete structure in embodiment and Figure of description.For other structure formations that those of ordinary skill in the art can know by inference, also belong within the present invention's scope required for protection.
Refer to Fig. 1, an accurate weighing system for brilliant equipment grown automatically by kyropoulos sapphire, and comprise the burner hearth 1 for arranging thermal field 2 and crucible, described burner hearth 1 is set to round shape, top arranges the upper bell 4 of sealing, and the center of described upper bell 4 arranges bell mouth 3.In order to by aluminium sesquioxide melting sources, the hot environment produced in described burner hearth 1 close to 2100 DEG C can be needed, and the quality needs formation high vacuum environment in described burner hearth 1 in order to ensure sapphire crystal.
Therefore, at described upper bell mouth 3, magnetic fluid 5 is set, the internal diameter of described magnetic fluid 5 arranges identical with the internal diameter of described upper bell 4 mouthful 3, described magnetic fluid 5 is fixed for 4 mouthful 3 by flange and described upper bell, arranging seed rod 6 through described magnetic fluid 5 and upper bell mouth 3 stretches into described burner hearth 1, and described seed rod 6 end arranges seed chuck.Described seed chuck can be used for binding seed crystal, for growing sapphire crystal.
Described seed rod 6 arranges belt pulley, and described belt pulley is connected with brilliant rotating motor 7 by belt 8.Described brilliant rotating motor 7 rotates and described seed rod 6 can be driven to rotate, for controlling the growth of crystal.
The Jing Sheng mechanism 11 that can move up and down is set.Described Jing Sheng mechanism 11 arranges brilliant lifting motor 10 and brilliantly rises screw mandrel 12, and described brilliant lifting motor 10 drives described crystalline substance to rise screw mandrel 12 to rotate, thus the Jing Sheng mechanism 11 described in drive is elevated.Described Jing Sheng mechanism 11 arranges through hole 13, is arranged symmetrically with the LOAD CELLS 12 of at least two around described through hole 13, described seed rod 6 is arranged in described LOAD CELLS 12, and through described through hole 13.In sapphire crystal growth process, load based on described seed rod 6, adding crystal weight is evenly distributed in described LOAD CELLS 12, the weight each LOAD CELLS 12 recorded is added, and the weight deducting described seed rod 6 just can obtain the actual weight of crystal.
In sum, the magnetic fluid 5 carrying out airtight effect is set at described upper bell mouth 3, namely realizes burner hearth 1 and extraneous vacuum-sealing, allow moving up and down of seed rod 6 again, eliminate traditional bellows structure, avoid the extra error of crystals weighed.
