Following with reference to accompanying drawing 1～10, describe embodiments of the present invention in detail.
As mentioned above, glass grumeleuse manufacturing installation of the present invention has the amount of the dripping adjustment component that has communicating pores, and the part that melten glass is dripped is passed communicating pores becomes tiny droplets, accepts this tiny droplets with receiving portion and forms the glass grumeleuse; Device for shaping glass of the present invention has above-mentioned glass grumeleuse manufacturing installation and is used for the patrix of compression molding, and the described glass grumeleuse with the condition of high temperature on the patrix mold pressing counterdie obtains glass forming body.
In the explanation of following embodiment, be that example describes with device for shaping glass and method.From device for shaping glass, remove patrix and just be glass grumeleuse manufacturing installation.In addition, the mold pressing procedure that removes the employing patrix from glass forming method is a glass grumeleuse manufacture method, can make the tiny droplets that drips on the counterdie become the glass grumeleuse.Also can form the glass preform by cooling curing glass grumeleuse.
Carry out the microminiaturization that melten glass drips with plate
Fig. 1 is the schematic configuration example diagrammatic cross-section of embodiment of the present invention glass grumeleuse manufacturing installation.With reference to Fig. 1, to the structure of present embodiment glass grumeleuse manufacturing installation and device for shaping glass, and the function that the melten glass that has of this device drips the amount of dripping adjustment component explains.
Among Fig. 1, the 35th, the drip nozzle that the melten glass that is used for dripping drips.The 36th, melten glass.The melten glass 36 that is molten to institute's fixed temperature in not having illustrated glass melting furnace is fed into drip nozzle 35, drips as shown in the figure from drip nozzle 35 tips.The 31st, the melten glass that drips drips, and its size (quality, volume) is by the melt temperature of melten glass 36 and the bore adjustment of drip nozzle 35 tips.
The 10th, plate, the 15th, be used for plate 10 is supported on the plate support component of institute's allocation.Constitute the amount of dripping adjustment component by this plate 10 and plate support component 15.
It is that central conflict is above plate 10 on 12 with communicating pores 11 that the melten glass that drips from drip nozzle 35 drips 31, its part is separated, pass communicating pores 11, drip on the optical function face (being designated hereinafter simply as function face, transfer surface) 23 that is configured in the counterdie 21 under the communicating pores 11 as the tiny droplets (being designated hereinafter simply as tiny droplets) 32 of melten glass.This counterdie 21 is equivalent to receiving portion.The back is described in detail with counterdie 21 and accepts moulding process after the melten glass tiny droplets 32.
Melten glass drips 31 directly not to be accepted with counterdie 21 but drips to make a part pass communicating pores 11 on the plate 10 to separate, supply on the counterdie 21 as the tiny droplets 32 of melten glass, and this is to have any problem because the melten glass that drips from drip nozzle 35 is dripped 31 microminiaturizations.
In recent years, follow the miniaturization of various Optical devices etc., the increase in demand of the small-sized glass forming body of diameter number millimeter degree, but be suitable for the quality of this small-sized glass forming body manufacturing, the melten glass tiny droplets of volume, the usefulness melten glass that drip such as drip nozzle in the past drip and are difficult to make.
It is to adjust by the melt temperature of melten glass 36 and the bore of drip nozzle 35 tips that the melten glass that drips from drip nozzle 35 drips 31 size (quality, volume), in order to make the melten glass 36 mobile drip nozzle footpaths that must guarantee to a certain degree, also have on the tip that melten glass 36 is moistening to be spread etc., so melten glass drips 31 lower limit in about 200mg degree.In addition, when hope change melten glass drips 31 sizes, must exchange drip nozzle 35, bigger to the influence of operation factor and cost.
By adopting aforesaid plate 10, can easily obtain tiny droplets 32 less than the 200mg size with communicating pores 11.In addition, as long as power board 10 just can easily change the size of tiny droplets 32.
Fig. 2 (a) is the state diagrammatic cross-section of melten glass when dripping 31 conflict plates 10 communicating poress 11; Fig. 2 (b) is the state diagrammatic cross-section after tiny droplets 32 is separated.With reference to Fig. 2, explain adopting plate 10 to make tiny droplets 32.
Among Fig. 2 (a), the 31st, the melten glass that drips from drip nozzle 35 drips 31.Expression is just towards the state of communicating pores 11 conflicts of plate 10.Communicating pores 11 inner peripheral surfaces 12 1 sides on lean on are tapered.Catch melten glass with this taper inner peripheral surface and drip 31.
Communicating pores 11 is small footpaths, and the melten glass of conflict drips a part of 31 and passes communicating pores 11, drips 31 from melten glass and separates.
Among Fig. 2 (b), the 32nd, pass communicating pores and drip 31 the tiny droplets of melten glass under separating, dripping from melten glass.The 33rd, the residue glass after tiny droplets 32 is separated, its on plate 10 on 12 with the state cooling curing in the embedding communicating pores 11.Remove and solidify residue glass 33, prepare next time melten glass and drip 31 and drip.
But when using plate 10, also distinctive problem might take place.One of them is that if communicating pores 11 footpaths deviation occurs because of certain reason, then tiny droplets 32 sizes and quality also might change.Also have, if communicating pores 11 has shift in position, then tiny droplets 32 is brought detrimentally affect to the shift in position of dripping of counterdie 21 to compression molding.
Especially during continuous operation, plate 10 constantly drips with melten glass and contact the temperature rising, so plate 10 expansion effects communicating poress 11 directly.Also have, words communicating pores 11 positions that plate support component 15 temperature rise will be departed under the drip nozzle 35.Also have, when adopting a plurality of plate 10 grades, the deviation of communicating pores size and surface roughness etc. between each plate also is the problem that must consider on the quality product.
In the present embodiment,, have temperature control device, the temperature of the temperature of switchboard 10 or plate support component 15 for these deviations are taken measures.
The temperature variation of plate and temperature control device
At first, the influence of temperature variation of not carrying out temperature when control is explained.Fig. 3 is in the device for shaping glass of present embodiment, is not having temperature control device to carry out under the temperature controlled state, during continuous operation, and the temperature variation profile of plate.
On plate 10 temperature sensing is installed, melts glass and compression molding continuous operation repeatedly under the molten drop, relative time changes through the temperature (longitudinal axis) of (transverse axis) assay plate, and the result is shown in curve G1.
Initial stage is the temperature of the plate 10 of room temperature degree, and with the process of runtime, the pyritous melten glass drips 31 conflicts, a part passes in a part of residual process and absorb heat being heated at every turn, and temperature rises rapidly.Process runtime of dripping afterwards along with melten glass repeatedly, the temperature of plate 10 rises and becomes gradually slowly, and after the temperature that acquires a certain degree, temperature rises and is in state of saturation.
Different according to different meetings such as the circulation of dripping repeatedly, glass melting temperature, plate 10 capacity, for example among Fig. 3 runtime through about 10 minutes, the temperature of plate 10 reaches about 180 ℃, maintains this temperature afterwards.
This is equivalent in entry into service initial about 10 minutes just about about 150 ℃ temperature variation.These communicating pores 11 sizes to plate 10 have a significant impact.That is to say, cause tiny droplets 32 variation of qualitys of passing communicating pores 11, finally cause the glass forming body mass deviation of compression molding.
The glass forming body mass deviation might cause the thick change of the heart and follow bad order of wavefront aberration of the thick change of the heart (mainly being spherical aberration) and moulding product etc.Especially concerning the high optics of the thick accuracy requirement of the heart, this mass deviation is serious problem.
In addition, plate 10 is supported on the also change equally of temperature of the plate support component 15 of institute's allocation with the temperature variation of plate 10.Since the thermal expansion that these temperature variations cause, the shift in position of plate 10, the i.e. shift in position of communicating pores 11.
By the plate support component 15 of arm shape, the center of the communicating pores 11 of plate 10 be positioned under the drip nozzle 35 and the transfer surface center of counterdie 21 directly over.Therefore, the shift in position of communicating pores 11 will cause following change: dripping of melten glass 31 departs from communicating pores 11 central positions; Or pass the drip position deviation of tiny droplets 32 on counterdie 21 of communicating pores 11.
Because the departing from of the above-mentioned position of dripping, the bad order of glass forming bodies such as the wavefront aberration that might cause the thick and face shape change of the heart of glass forming body, cause by the former, crack.Especially very big to the same influence of the high optics of the thick accuracy requirement of the heart.
Following with reference to Fig. 4～Fig. 7, temperature control device is elaborated.
The function of temperature control device is divided into two major parts:
(1) control makes the temperature of plate or plate support component remain on specified temperature, suppresses to drip to the mass deviation of the tiny droplets on the counterdie or the position deviation of dripping;
(2) temperature of switchboard or plate support component, adjustment makes the quality that drips to the tiny droplets on the counterdie or drips the position respectively in deciding scope.
Above-mentioned two partial functions are realized by the temperature control device of following explanation.Being intended that of function (1) suppresses the thermal expansion change that temperature causes, realizes improving the quality of products and operation factor; Being intended that of function (2) adjusted, and realizes controlling with temperature compensating based on the mass deviation of the changes of creating conditions such as communicating pores dimensional variations between a plurality of plates etc.
Effective function when being following device for shaping glass situation (2).
Even temperature-resistant, the tiny droplets size of passing the plate communicating pores also can be owing to other condition variation change.For example the quality of tiny droplets can since the surface roughness inhomogeneous, the in addition face (glass contact face) above the plate of plate communicating pores size etc. change.
In same device for shaping glass, when a drip nozzle is prepared a plurality of plates and is used alternatingly these a plurality of plates to make, the quality of the tiny droplets of dripping when using each plate has deviation, must take measures in order to assemble these plates, promptly from a plurality of plates, select to use the plate that can access accurate scope tiny droplets quality.
Adjust this moment, realizes controlling with temperature compensating based on the mass deviation of the creating conditions change between a plurality of plates etc., then can bring into play function effectively.
In the past, the quality adjustment of passing the tiny droplets of plate communicating pores was to be undertaken by the temperature adjustment of drip nozzle tip.But, change the viscosity change of the words melten glass of drip nozzle temperature, so must change condition of molding.In contrast to this, the method for regulating temperature of above-mentioned switchboard can reduce melten glass is dripped the influence of other characteristic outside the quality.
Reason is that melten glass drips the poor of residence time.Melten glass is detained the long period at the drip nozzle tip, but is in a flash in the plate communicating pores.
Like this, by controlling the temperature of each plate respectively, can not influence other plate glass ware forming be adjusted at the quality of the tiny droplets of this plate.
Below, be 2 different examples with the design temperature of controlling, the structure that realizes the temperature control device of these functions in the present embodiment device for shaping glass is described.

The 52nd, power supply is used in heating, is used for heating respectively heating unit 53a and 53b.Heating according to the control signal of control device 51, controls each heating unit to plate 10 and plate support component 15 with power supply 52 respectively, be that the power supply of heating unit 53a and 53b is supplied with.
The function of above-mentioned each key element of control device 51 controls.That is to say, accept detected plate 10 and plate support component 15 temperature signal separately from sensing detection portion 54, each specified temperature with prior setting is that controlled target is carried out temperature relatively, whether determine hot-plate 10 and plate support component 15 respectively, according to decision, the control signal of respectively power supply of heating unit 53a and 53b being supplied with is sent to heating power supply 52.
Be the specified temperature of controlled target, can consider temperature controlled energy supply, suitably decision.Carry out temperature when control among the said temperature controlling organization A, with specified temperature be set at respectively than do not carry out continuous operation under the temperature state of a control, the temperature of plate 10 before melten glass dripped and will pass when temperature reached steady state or the high temperature of temperature of plate support component 15.
This be because melten glass to drip 15 temperature head of 31 temperature and plate 10 and plate support component more little, the temperature variation that melten glass drips 31 plates 10 when passing plate 10 and plate support component 15 is more little, so can carry out more stabile temperature controlled relation.
Specifically then be preferably as follows and carry out temperature control: do not have temperature control device to carry out continuous operation under the temperature state of a control, the temperature T when temperature reaches steady state ℃ relatively, set the specified temperature below T+300 ℃ more than T+1 ℃.This is because the temperature of plate is too high, remains in the relation that the residue glass 33 on the plate 10 is difficult to remove.
Certainly, according to the various drive condition situations of device for shaping glass, temperature control the time also can be set at specified temperature the low temperature of temperature when reaching steady state.This temperature control device will be narrated in the back.
A can realize the function of above-mentioned (1) by the said temperature controlling organization.That is to say that the temperature of switchboard 10 and plate support component 15 makes to remain on specified temperature, can suppress to drip to the mass deviation of the tiny droplets 32 on the counterdie 21 or the position deviation of dripping.
In addition, the function of above-mentioned in order to realize (2) is as long as additional following controlled target is set in the temperature control that control device 51 is done.
When for example in same device for shaping glass, being used alternatingly a plurality of plate 10, each plate 10 is set at the specified temperature of controlled target respectively.Each specified temperature is set at for example makes communicating pores size deviation etc. between each plate of compensation.To each plate 10 or plate support component 15 difference controlled temperature, can adjust the quality that makes the tiny droplets 32 that drips on the counterdie 21 or drip the position respectively in deciding scope like this.
Temperature control device configuration example 2
Fig. 6 is the configuration example block diagram of temperature control device B.Fig. 7 is the configuration example diagrammatic cross-section ((a) orthographic plan, (b) front elevation) of cooling body of the plate of temperature control device B.With reference to Fig. 6, Fig. 7, the 26S Proteasome Structure and Function of temperature control device B is described.
55 is refrigerating units among Fig. 6, is made of for example refrigerant cooling device etc., and the water coolant of controlled temperature is circulated in cooling tube 57.Cooling tube 57 is embedded in and is configured in the plate 10 for example as shown in Figure 7, by flowing into water coolant etc. plate 10 is cooled off.Cooling tube 57 has been installed temperature sensing, is used for carrying out the thermometric of plate 10.Temperature sensing also can be separated with cooling tube 57 and is provided in separately in the plate 10.Cooling tube 57 sets around communicating pores 11 in Fig. 7, but its size, equipping position, the mode of setting are arbitrarily.
Cooling tube 57 also passes in plate support component 15.Cooling tube 57 has also been installed and has been used for carrying out plate support component 15 thermometric temperature sensing.Certainly temperature sensing also can set separately.Size, the equipping position of the cooling tube 57 in the plate support component 15, the mode that sets are identical with the situation of plate 10, are arbitrarily also.
Only shown 1 cooling tube 57 that is provided in the plate 10 among Fig. 7, but also can be in plate support component 15, also to set cooling tube 57 (and temperature sensing) separately, independent respectively control both sides' cooling.At this moment, by refrigerating unit shown in Figure 6 55, in each cooling tube 57 independent controlled chilling discharge of plate 10 and plate support component 15.Certainly, also can only set one and carry out temperature control according to the control intention.
Only shown the relevant integrant of cooling among Fig. 6 and Fig. 7, still,, preferably possessed the heating associated mechanisms as shown in temperature control device A simultaneously from improving temperature controlling efficiency and degree of freedom viewpoint.
The 54th, from the sensing detection portion of each temperature sensing detected temperatures signal of being installed in cooling tube 57.Or from the sensing detection portion of each temperature sensing detected temperatures signal of being provided in plate 10 and plate support component 15 separately.Sensing detection portion 54 is sent to control device 51 with each temperature signal of detected plate 10 and plate support component 15.
When having the heating arrangements described in temperature control device A simultaneously, control device 51 also carries out the control of the heating unit described in temperature control device A simultaneously.
Temperature control device B has the intention of cooling body, is because of being different from temperature control device A for the specified temperature of controlled target.Carry out temperature when control among the said temperature controlling organization B, with specified temperature be set at than do not carry out continuous operation under the temperature state of a control, the temperature of plate 10 before melten glass will pass when temperature reaches steady state or the low temperature of temperature of plate support component 15.
This is because be set at the operation factor that the temperature lower than the temperature of plate 10 can improve device for shaping glass.As previously described, the melten glass that drips on the communicating pores 11 of plate 10 drips 31, separation is a part of falls to counterdie 21 as tiny droplets 32, must cool off, solidifies, remove the residue glass of staying on plate 10 communicating poress 11 33 then before next drip melt that drips from drip nozzle 35 again melts glass drop 31.The temperature of plate 10 is low more, can cool off quickly more, solidifies, remove.Therefore, can shorten from drip nozzle 35 melten glass that drips and drip 31 interval, improve the operation factor of device for shaping glass.
Specifically then be preferably as follows and carry out temperature control: do not have temperature control device to carry out continuous operation under the temperature state of a control, the temperature T when temperature reaches steady state ℃ relatively, set the specified temperature below T-1 ℃ more than T-200 ℃.This is because the temperature of plate is too low, and the melten glass tiny droplets 32 of passing plate 10 produces the relation of devitrification.
The situation of above-mentioned and foregoing temperature control device A is identical, temperature control device B also can realize above-mentioned can (1).That is to say that the temperature of switchboard 10 and plate support component 15 makes the maintenance specified temperature, can suppress to drip to the mass deviation of the tiny droplets 32 on the counterdie 21 or the position deviation of dripping.
In addition, the function of above-mentioned in order to realize (2) in the control of the temperature of control device 51, for example is set at the specified temperature of controlled target respectively to each of a plurality of plates of using.Like this can be to each plate 10 or plate support component 15 difference controlled temperature, adjustment makes the quality of the tiny droplets 32 that drips on the counterdie 21 or drips the position respectively in deciding scope.Also the situation with temperature control device A is identical for these, detailed.
The manufacture method of glass forming body
With reference to Fig. 8～Figure 10, the manufacture method made from the device for shaping glass of embodiment of the present invention is explained.
Fig. 8 is the manufacture method one routine flow process made from the device for shaping glass of embodiment of the present invention.Fig. 9, Figure 10 are the mode charts that is used for illustrating glass forming body manufacturing process, and Fig. 9 represents to separate the state (operation S24) of tiny droplets 32 by plate 10, and Figure 10 represents the state (operation S26) with counterdie 21 patrixes 22 extrusion forming tiny droplets 32.
22 is patrixes among Fig. 9, Figure 10, is used for counterdie 21 extrusion forming tiny droplets 32.Patrix 22 is identical with counterdie 21, can not be heated to institute's fixed temperature by there being illustrated heating unit.Preferably can independently carry out temperature control respectively to counterdie 21 patrixes 22.
According to flow process shown in Figure 8 each operation is described successively below.
At first, counterdie 21 patrixes 22 are heated to institute's fixed temperature (operation S21).Institute's fixed temperature can suitably select can form by extrusion forming the temperature of good transfer surface on glass forming body.The Heating temperature of counterdie 21 patrixes 22 can be the same or different.
In the present embodiment, as mentioned above, carry out the temperature control of plate 10 or plate support component 15 by temperature control device.When glass forming body is made, at first be controlled at specified temperature.
Make counterdie move to the position of dripping (P1 position shown in Figure 9) (operation S22) then.
Subsequent, drip 31 (operation S23) from drip nozzle 35 melten glass that drips.Melten glass drips 31 following the carrying out of dripping.Heated melten glass 36 is not fed into drip nozzle 35 in having illustrated melting furnace, under this state drip nozzle 35 is heated to institute's fixed temperature, and melten glass 36 just passes the stream that drip nozzle 35 inside are provided with because of deadweight, because of surface tension is accumulated in first end.In case accumulate the melten glass of certain mass, just the nature from drip nozzle 35 first end parts from, the melten glass of certain mass drips 31 and drips downwards.
The melten glass that drips drips 31 quality and can adjust by the external diameter of drip nozzle 35 first ends.In addition, can wait by internal diameter, length, the Heating temperature of drip nozzle 35 and adjust melten glass and drip 31 drip at interval.Therefore, by these conditions of suitable setting, can drip 31 with the drip melten glass of the quality of being hoped of the interval of being hoped.
As long as the melten glass that drips from drip nozzle 35 drips 31 quality greater than the tiny droplets 32 of being hoped, be the size that the communicating pores 11 of conflict plate 10 can be isolated tiny droplets 32.
Subsequent, separate tiny droplets 32 by plate 10 and supply to counterdie 21 (operation S24).Conflict above plate 10 on 12 in case melten glass drips 31, melten glass drips a part of 31 and just passes communicating pores 11 owing to impacting, and is separated into tiny droplets 32.
Melten glass when conflicting to plate 10 drips 31 temperature, so long as viscosity is low to getting final product by the temperature that the degree of tiny droplets 32 is isolated in conflict, does not have particular determination.
Surging force during conflict changes with the distance between drip nozzle 35 tips and the plate 10, by considering chosen distance suitably such as said temperature condition simultaneously, can access the tiny droplets 32 of the quality of hoping.
As top in detail as described in, be that specified temperature ground is controlled by the temperature that makes plate 10 and plate support component 15, the position deviation in the time of can making the mass deviation of tiny droplets 32 and supply on the counterdie 21 is minimum.
Subsequent, mobile counterdie 21 is to the position P1 (operation S25) that drips, and mobile patrix 22 is to the below, with counterdie 21 patrixes 22 extrusion forming tiny droplets 32 (operation S26).
Dripped (supplys) tiny droplets 32 to the counterdie 21 during extrusion forming, by coolings such as heat release, curing from the contact surface of contact counterdie 21 patrixes 22.Even after being cooled to be formed on transfer surface shape on the glass forming body 34 and removing the temperature that pressurization can be not out of shape yet, remove pressurization.
The subsequent patrix 22 that makes is kept out of the way, and reclaims glass forming body 34 (operation S27), removes the residue glass 33 (operation S28) that remains in the plate 10, and the manufacturing of glass forming body is finished.Subsequent when proceeding glass forming body and making, can mobile once more counterdie 21 to the position P1 (operation S22) that drips, operation S23～operation S28 repeatedly.
The manufacture method of glass forming body of the present invention can also comprise other operation except the operation of this explanation.For example, the operation of checking the glass ware forming shape can be before reclaiming glass forming body, established, the operation of cleaning counterdie 21 and patrix 22 etc. can also be after reclaiming glass forming body, established.
The glass forming body made from manufacture method of the present invention can be as the optical pickup lens of the imaging lens system of digital camera etc., DVD etc., the various optical elements such as coupled lens that optical communication is used.
As initial described, device for shaping glass of the present invention has glass grumeleuse manufacturing installation, is the device that the high glass grumeleuse of the mold pressing condition of high temperature obtains the glass ware forming thing.Remove operation (operation S25 and S26) from above-mentioned glass ware forming operation, can obtain in operation S24, supplying to tiny droplets on the counterdie as the glass grumeleuse with the patrix mold pressing.
That is to say that the also above-mentioned glass grumeleuse of cooling curing for the time being is used for making by heated-die pressing process again the preform of optical element.
