Abstract
The utility model discloses an apparatus for centering adjustment of a seed crystal and a crucible in a crystal growth furnace. The apparatus comprises a chuck, a laser pen and a disk with a ruler, wherein the chuck with the laser pen is fixed on a seed crystal rod, the axis core of the laser pen coincides with the axis core of the seed crystal rod, the disk with the ruler is arranged on the upper edge of the crucible opening, the size of the outer cycle of the disk and the outer cycle of the crucible maintain the same. The apparatus has the following advantages that: the problem that the seed crystal rod and the crucible are inconvenient to center can be solved, measurement on the distance between the tip of a plumb and the inner wall of the crucible is not required, and characteristics of convenience and applicability are provided.
Description
Technical field
The utility model relates to a kind of debugging apparatus for crystal growing furnace, particularly a kind of device for crystal growing furnace seed crystal and the debugging of crucible centering
Background technology
The sapphire crystal stove is the equipment of growing sapphire crystal, mainly by concubine 8, and body of heater 9, bell 10, furnace bottom 11, heating system 12, heat-insulation system 13, crucible 14, crucible pole 15 forms, wherein body of heater is drum, and upper and lower opening is by bell and furnace bottom sealing body of heater, bell center and furnace bottom center and body of heater axis coinciding, bell is provided with vision slit 16, concubine is positioned at the bell center, concubine axle center and body of heater axis coinciding, and seed rod is settled along axis direction in concubine inside.It is inner that crucible is placed body of heater by crucible pole, and its axle center is concentric with body of heater, settles heating system and heat-insulation system between crucible and the body of heater.
One of committed step of growing crystal is the axis coinciding that guarantees crucible and seed rod, usually the method that adopts is to be connected on the seed rod with plummet, take plummet as standard, adjust bushing position by the distance between measurement plummet tip and the crucible inwall and guarantee that seed rod and crucible are concentric.But because body of heater is closed system, heating system is equipped with in inside, heat-insulation system, and crucible, narrow space, visual range is little, uses the plummet adjustment to be inconvenient to observe and measure with one heart.
Summary of the invention
The purpose of this utility model provides a kind of device for crystal growing furnace seed crystal and the debugging of crucible centering, this device can solve the problem of seed rod and crucible centering inconvenience, simultaneously do not need to measure the distance between plummet tip and the crucible inwall, easy, applicable.
To achieve the above object of the invention, the utility model is by the following technical solutions:
This device for crystal growing furnace seed crystal and the debugging of crucible centering, it comprises: chuck, laser pen reach the disk with scale, at the fixing chuck with laser pen of seed rod, the axle center of its laser pen and the axis coinciding of seed rod; Disk with scale is installed in edge on the mouth of pot, and the disk excircle dimension is consistent with the crucible cylindrical.
Chuck is connected with seed rod with positioning screw hole I by dog screw I, and laser pen is connected with chuck with positioning screw hole II by dog screw II.
The quantity of described dog screw I, positioning screw hole I is respectively at least 3, and at grade uniform.
The quantity of described dog screw II, positioning screw hole II is respectively at least 3, and at grade uniform.
The scale of described disk is that cross shape is simultaneously with scale.
The utility model has the advantages that: this device can solve the problem of seed rod and crucible centering inconvenience, does not need to measure simultaneously the distance between plummet tip and the crucible inwall, and is easy, applicable.
Description of drawings
Fig. 1: in this device at the structural representation of the fixing chuck with laser pen of seed rod
Fig. 2: disc structure synoptic diagram in this device
Fig. 3: this device is installed on the structural representation of sapphire crystal stove
Among Fig. 1, Fig. 2, Fig. 3,1 is seed rod, and 2 is laser pen, and 3 is chuck, and 4 is dog screw I, and 5 is positioning screw hole I, and 6 is dog screw II, and 7 is positioning screw hole II.
Embodiment
At seed rod 1 fixing chuck 3, the axle center of its laser pen and the axis coinciding of seed rod with laser pen 2.Chuck 3 is connected with positioning screw hole I by dog screw I 4 and is connected with seed rod 1, and laser pen 2 passes through dog screw II 6 is connected with positioning screw hole II and is connected with chuck 3, as shown in Figure 1.
On mouth of pot along laying disk with scale, the scale of disk be cross shape simultaneously with scale, the disk excircle dimension is consistent with the crucible cylindrical, disk as shown in Figure 3.
By opening laser pen, observe the position of laser facula on Cross Scale by vision slit during centering, adjust the position of crucible, the centering of finally finishing seed rod and crucible according to the size of position display.
The fixedly employing of laser pen and seed rod has axisymmetric chuck and realizes that the profile of laser pen need to have axially symmetric structure, to realize being connected of laser pen and chuck, usually can adopt cylindrical.
Claims (5)
1. device that is used for the debugging of crystal growing furnace seed crystal and crucible centering, it is characterized in that: it comprises: chuck, laser pen reach the disk with scale, at the fixing chuck with laser pen of seed rod, the axle center of its laser pen and the axis coinciding of seed rod; Disk with scale is installed in edge on the mouth of pot, and the disk excircle dimension is consistent with the crucible cylindrical.
