Abstract
The utility model provides an auxiliary crystal growing apparatus with double weighing instruments, which comprises a rotary device and weighing instruments. The weighing instruments are arranged on the rotary device. The rotary device comprises a carriage, and a seed crystal rotation servo, a bearing seat and a seed crystal rod which are respectively connected with the carriage and are arranged coaxially; and the weighing instruments are arranged on the carriage. The auxiliary crystal growing apparatus with the double weighing instruments also further comprises a pair of middle platforms, and the middle platforms are arranged on the carriage. The auxiliary crystal growing apparatus with the double weighing instruments can precisely adjust the output power and control the long crystal temperature in a thermal field, which is the premise for obtaining high-quality crystal; then the highest growth rate is obtained as much as possible according to the normal weight change of crystal growth, so that the long crystal cost is reduced, and the production efficiency is improved. When the crystal needs to be separated from a crucible, whether the crystal is adhered to the inner wall of the crucible can be judged according to the change of the data of the weighing instruments.
Description
Technical field
The utility model relates to the sapphire single-crystal production field, particularly a kind of two weighing instrument aiding crystal growth devices that are used for the Sapphire Crystal Growth stove.
Background technology
In traditional sapphire single-crystal production technique, can whole crystal growing process be divided into four control stages usually, i.e. seeding, shouldering, isometrical, annealing and colling stages.In the continuous process of growth of crystal, except crystal-tipped need draw high, all the other only needed the variation of controlled temperature, and controlled chilling speed makes monocrystalline down solidify gradually from the top, and final set becomes a whole monocrystalline crystal ingot.
When seeding, if growth velocity is too fast, the expression temperature descended low, must heighten temperature; If crystalline growth velocity is too slow, or crystal seed has melting phenomenon, and the expression temperature is too high, must downgrade temperature.Adjust temperature by crystalline growth velocity, make crystal obtain best growth temperature.
When temperature is adjusted to the most suitableization, the beginning isodiametric growth stage.Seed crystal stops to lift, and only need downgrade magnitude of voltage with automated manner, and temperature is slowly descended, liquation just in crucible from the monocrystalline interface that seed crystal extended out, slowly be frozen into a whole monocrystalline crystal ingot from top to bottom.Isometrical process is consuming time the longest in the whole process flow, influences into a link of brilliant quality the most easily, but according to present process method, and under the prerequisite that guarantees crystal mass, the maximum that can't obtain growth velocity is value the soonest.
When crystal growth finishes, when starting crystal disengaging crucible program, can't from range estimation, judge whether crystal bonds to the crucible inwall.Directly the related crucible of pulling crystal meeting possibly cause crucible to come off, and produces unnecessary loss.
The utility model content
For solving the problems of the technologies described above, the utility model provides in a kind of realization crystal growing process, the maximization of growth velocity, and avoid crucible and crystal adhesion directly to lift two weighing instrument aiding crystal growth devices of dislocation.
The two weighing instrument aiding crystal growth devices of the utility model comprise: swivel arrangement; Weighing instrument, said weighing instrument is arranged on the said swivel arrangement.
Said swivel arrangement comprises: bracing frame; Be connected with support frame as described above respectively, seed crystal rotating servo, chock and the seed rod of coaxial setting; Said seed crystal rotating servo, said chock and said seed rod belong to the plane perpendicular to support frame as described above; Said weighing instrument is arranged on the support frame as described above.Said pair of weighing instrument aiding crystal growth device also further comprises a centering platform, and said centering platform is arranged on the support frame as described above.
The two weighing instrument aiding crystal growth devices of the utility model can accurately be adjusted output rating, control the brilliant temperature of length of hot on-site, are to obtain high-quality crystalline prerequisite.According to the normal weight changing value of crystal growth, obtain optimum growth speed as much as possible then, reduce long brilliant cost, enhance productivity.When the needs crystal breaks away from crucible,, can judge crystal and whether adhere to the crucible inwall through data variation from weighing instrument.

Embodiment
Below in conjunction with accompanying drawing the two weighing instrument aiding crystal growth devices of the utility model are done further explain.
As shown in Figure 1, the two weighing instrument aiding crystal growth devices of the utility model, comprising: swivel arrangement and weighing instrument are arranged on the weighing instrument 3 on the bracing frame 5.
Swivel arrangement comprises: bracing frame 5; Be connected with bracing frame 5 respectively and seed crystal rotating servo 1, chock 2 and the seed rod 6 of coaxial setting each other; Seed crystal rotating servo 1, chock 2 and seed rod 6 are perpendicular to plane, bracing frame 5 place.The two weighing instrument aiding crystal growth devices of the utility model comprise further that also one is arranged on the centering platform 4 on the bracing frame 5.
The two weighing instrument aiding crystal growth devices of the utility model can accurately be adjusted output rating, control the brilliant temperature of length of hot on-site, are to obtain high-quality crystalline prerequisite.According to the normal weight changing value of crystal growth, obtain optimum growth speed as much as possible then, reduce long brilliant cost, enhance productivity.When the needs crystal breaks away from crucible,, can judge crystal and whether adhere to the crucible inwall through data variation from weighing instrument.
The two weighing instrument aiding crystal growth devices of the utility model have increased the weighing instrument subsidiary function on the basis of control crystal hoisting appliance, accurately adjust output rating, control the brilliant temperature of length of hot on-site, are to obtain high-quality crystalline prerequisite.According to the normal weight changing value of crystal growth, obtain optimum growth speed as much as possible then, reduce long brilliant cost, enhance productivity.When the needs crystal breaks away from crucible,, can judge crystal and whether adhere to the crucible inwall through data variation from weighing instrument.
The preferred embodiment of below the utility model having been created specifies; But the utility model is created and is not limited to embodiment; Those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
