Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model.
Reference numeral in figure is: 1 corrugated tube support; 2 quartz glass bars; 3 quartz glass bar folders; 4 cylinders; 5 stay wire sensors; 6 corrugated tubes; 7 polycrystalline silicon ingot or purifying furnaces; 8 silicon liquid liquid levels; 9 quartz crucibles; 10 solid-liquid interfaces.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
As shown in Figure 1, a kind of polycrystalline ingot furnace is automatically surveyed long brilliant device and is comprised corrugated tube support 1, quartz glass bar 2, quartz glass bar folder 3, cylinder 4, stay wire sensor 5 and corrugated tube 6, is arranged on the furnace roof of polycrystalline ingot furnace 7.Quartz glass bar 2 is arranged on the furnace roof viewing window place of polycrystalline ingot furnace 7, the inside of polycrystalline ingot furnace 7 is stretched in one end of quartz glass bar 2, the other end is arranged in corrugated tube 6, in the outside of polycrystalline ingot furnace 7, the quartz glass bar 2 admission port place of polycrystalline ingot furnace 7 is sealed by one end of corrugated tube 6.Upper surface and the quartz glass bar of corrugated tube 6 press from both sides 3 and are together fixed on the corrugated tube support 1 that is connected with cylinder 4 piston rod.Cylinder 4 moves up and down for driving corrugated tube 6, and then drives the stay cord on quartz glass bar 2 and stay wire sensor 5 to move up and down.Stay wire sensor 5 for by the data recorded that moved up and down by stay cord, is converted to simulating signal and is sent in outside control module, and control module is for showing the data that record and carrying out record to data.When quartz glass bar is inserted and touches solid-liquid interface 10 in stove for 2 times, the length that the stay cord of stay wire sensor 5 is drawn out namely be quartz glass bar 2 lower surface from starting position to solid-liquid interface 10 distance, by stay wire sensor 5, the data obtained being converted to simulating signal is again sent on the operation interface of service platform, by control module record, thus the personnel of being convenient for measuring check, because crystal grows, solid-liquid interface 10 raises, one group of range measurements changed is drawn through the repetitive measurement with constant duration, and measuring result draws the brilliant speed of the length of polycrystalline ingot furnace 7 in this time period by control module direct analysis.
Cylinder 4 should by determining that the size of reactive force determines the cylinder diameter of required cylinder 4.Cylinder diameter is too small, and reactive force is inadequate, then quartz glass bar 2 possibly cannot touch solid-liquid interface 10; And cylinder diameter is excessive, then quartz glass bar 2 may insert solid-liquid circle 10 and excessively deeply causes damaging, and simultaneously equipment is heavy, and cost improves, and increases air consumption again, wastes energy.
Cylinder 4 has two kinds of reactive forces when working: a kind of is tensile force f 1 when moving upward, namely bear the total force of corrugated tube support 1 and quartz glass bar 2 and corrugated tube 6, add the frictional force produced when elastic force when corrugated tube 6 stretches and quartz glass bar 2 move; Another kind is thrust F2 when moving downward, when cylinder 4 works, the F1=F2 when air pressure is identical, and due to corrugated tube 6 be not spring, the elastic force that its stretching produces within the scope of normal travel is very little negligible, when moving up and down equally, only there is running fit quartz glass bar 2 and corrugated tube 6 lower end, and its frictional force produced is very little also negligible.If the gross weight calculating corrugated tube support 1 and quartz glass bar 2 and corrugated tube 6 is 5kg, i.e. F1=50N, if set safety coefficient as 0.2 that is cylinder 4 can promote the minimum force Fmin=250N of quartz glass bar 2, and be 0.2Mpa ~ 0.6Mpa according to cylinder 4 working pressure range, the cylinder diameter scope of optional cylinder 4 namely can be calculated according to the working pressure range of cylinder 4.
The cylinder diameter of cylinder 4 meets formula:
wherein, D refers to cylinder diameter, reactive force suffered when F refers to that cylinder 4 works, and P refers to operating pressure, and operating pressure P is 2kgf ~ 6kgf.Therefore show that the cylinder diameter of cylinder 4 is between 7.283mm ~ 12.616mm.
During work, a kind of polycrystalline ingot furnace is surveyed automatically the furnace roof viewing window place that long brilliant device is fixed on polycrystalline ingot furnace 7, load onto quartz glass bar 2, make quartz glass bar 2 be in highest point.Then, quartz glass bar 2 be placed in corrugated tube 6 inside and be fixed on quartz glass bar folder 3, upper surface and the quartz glass bar of corrugated tube 6 press from both sides 3 and are together fixed on the corrugated tube support 1 that is connected with cylinder 4 piston rod, the stay cord head of stay wire sensor 5 is fixed on quartz glass bar folder 3, like this when cylinder 4 drives corrugated tube 6 to move downward, quartz glass bar 2 also with under insert and drive the stay cord head of stay wire sensor 5 to move downward, until touch solid-liquid interface 10 in stove, the slotting distance of the Distance geometry quartz glass bar that the stay cord of stay wire sensor 5 is drawn out 2 times is identical, the variable quantity of the pulling rope length measured by stay wire sensor 5 just can calculate the height location of quartz glass bar 2.
Finally, converting the numerical value recorded to simulating signal by stay wire sensor 5 is sent on the operation interface of teller console, just can see the position of this quartz glass bar 2 of record, namely the difference of altitude of twice measurement is the height of crystal growth in twice interval time of measurement.
Finally, it should be noted that above what enumerate is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have a lot of distortion.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed in the utility model, all should think protection domain of the present utility model.
