The hot artifactitious source of difference fusion draw machine may be different.Hot artifactitious one of glass tape is latent
It is FDM design in source, if for example, it is not by the single continuous material system across the width for drawing section to draw section encapsulating wall
Make.Another hot artifactitious potential source of glass tape is probably right in the equipment inserted in FDM, such as insertion drawing section
Draw the temperature measuring equipment that the heat radiation in section measures.Another artifactitious potential source of heat is probably glass tape
The unevenly spaced distance between wall is encapsulated with draw machine, this may be related to FDM design, or the thickness with glass tape
Change is related, and the thickness change of the glass tape is due to caused by for example drawing temperature control poor in section.If in glass
When band is in viscosity or visco-elastic state, the hot artefact of glass tape be present in glass tape, then the hot artefact of glass tape can
Stress can be induced in glass tape.In glass solidification zone, the stress of induction may be solidified in glass.The induction of the solidification

Stress curve.It is understood, however, that the temperature curve in addition to the temperature curve shown in Fig. 3 can preferably be applied to
Other kinds of technique and other glass compositions.
When glass flow rate increase, the thermal capacity increase of FDM glass is flowed through.Because the heat carried secretly in glass increases
Add, glass tape is not cooled down with the speed needed for it, and this can cause high stress and cracking.As shown in figure 4, in 2x glass flow rates and
In the case of not having any type of cooling, the temperature curve (being shown as curve 410) of section is drawn from the glass of 1x glass flow rates
The datum temperature curve (being shown as curve 420) of band is offset up.The skew of the temperature curve may cause glass tape due to not

The accurate control of the temperature curve of the glass tape in drawing section under flow.In some embodiments, increase will can be in
Glass flow rate under drawing section in glass tape temperature curve (being shown as curve 430) be improved to and the baseline temperature under 1x flows
Line 420 of writing music is same or similar.In some embodiments, this method may include about 2x glass flow rate or even about
For 3x glass flow rate.In other embodiments, this method may include about 4x glass flow rate or even be about 5x's
Glass flow rate.
Except control draws the temperature curve in section, the embodiment of the method disclosed herein can be used for control fluid to
On flow through to draw and section and be downward through drawing section.The direction and amount for flowing through the fluid for drawing section can be controlled, with
The introducing of impurity is reduced, introducing for the impurity may cause to the quality of the glass tape when pulling glass tape by drawing section
Negative effect.If for example, fluid draw section top enter and down through transition portion 210, may be in transition
Boron vapour present in region 210 pulls downward on boron vapour by drawing section to cool down such as fluid.The boron vapour it is cold
But boron vapour may be caused to be condensed thereon with being cooled in for glass tape, this is departing from desired.Similarly, if high volume
Fluid from the flows of section are drawn to the top for drawing section, the solid particle existing for draw the bottom of section may be by
Fluid is carried upwardly through drawing section, and is deposited on viscous glass.The solid particle of these depositions is referred to as pollutant
(onclusion), they are departing from desired.Temperature curve except controlling glass tape, each embodiment can use
Fluid extraction and/or fluid are injected to control fluid to flow through drawing section up and down.It should be understood that noted for fluid
Enter or fluid extraction controls the determination of selection for drawing the flow of fluid in section can be based not only on required temperature curve, may be used also
Change based on flow of fluid required in the flow of fluid and drawing section drawn in section.
According to some embodiments, the temperature change of glass tape can be provided from section withdrawn fluid is drawn, such as such as Fig. 5 A
It is shown.For fluid extraction, the change of the temperature curve of glass tape can provide the glass tape of the close bottom for drawing section most
Big temperature change, the temperature variation curve of this and required glass tape as shown in Figure 3 is not close consistent.
In some embodiments, the temperature curve of glass tape as shown in Figure 5 B can be provided by fluid being injected into drawing section
Change.Injected for fluid, the change of the temperature curve of glass tape is in the position of injection fluid or close to the position of injection fluid
Put with maximum.For example, in figure 5b, the position for injecting fluid is lower than the root 139 of glass tape about 125 in section is drawn
The position of inch, thus the maximum change of the temperature curve of glass tape also be located at drawing it is lower about than the root 139 of glass tape in section
125 inches of position.Embodiments disclosed herein combines fluid extraction and fluid injection, with when the temperature of glass tape song
During the target temperature profile of line deviation glass tape as shown in Figure 3 (for example, when glass flow rate is increased above 1x, following article
It is described), the temperature curve of glass tape is controlled.Although below relate to the glass tape caused by the increase of glass flow rate
The change of temperature curve, the method disclosed herein can be used for the reality to the glass tape caused by arbitrary temp artefact
Temperature curve is adjusted relative to the skew of target temperature profile.
Can be by any conventional technique, the change to the temperature curve of the glass tape in the drawing section during 1x glass flow rates
Change measures.According to some embodiments, the change of the temperature curve of glass tape can be similar to curve as shown in Figure 3.
After the temperature curve change for measuring the glass tape in the case of the drawing section of 1x glass flow rates, it may be determined that multiple to be used to note
Enter fluid or from draw section withdrawn fluid port.The quantity of port and position are not specifically limited, and can be based on cost

Or from draw section withdrawn fluid port.In some embodiments, draw section may include three or more be used for inject stream
Body or from the port for drawing section withdrawn fluid, such as four or more ports.In other embodiments, drawing section may include
Five or more are used to injecting fluid or from the port for drawing section withdrawn fluid, or even six or more ports.
In some other embodiments, drawing section may include that seven or more are used to injecting fluid or from the end for drawing section withdrawn fluid
Mouthful, or even eight or more ports.Any known mechanism can be used to inject fluid into draw in section.At some
In embodiment, pump or pressure fluid can be used to inject fluid into and draw in section.Can use any known mechanism from
Draw section withdrawn fluid.In some embodiments, pump or vacuum source can be used from drawing section withdrawn fluid.
Inject fluid into and draw in section or be not specifically limited from the flow for drawing section withdrawn fluid, and depend on
Required cooling and other thermal characteristics of drawing section, different drawing sections can be with mutually different.In some embodiments, phase
For fluid in the case where being not injected into or extracting by drawing the baseline flow measurement of section, come measure fluid be injected into draw section in
Or the flow from drawing section withdrawn fluid.For example, no fluid be injected into draw section in or from draw section withdrawn fluid
In the case of, when fluid is moved through drawing section (for example, from the top to the bottom or from bottom to top)；The fluid flow can
It is considered baseline flow measurement.In some embodiments, baseline fluid flow may be about 0.010-0.040m3/ s, or even

Even about 0.022-0.025m3/s.It is understood, however, that the different baseline fluid flows for drawing section can change quite
Greatly, therefore, other baseline flow measurements are not fallen outside the scope of the invention.
It need not inject fluid into and draw in section or from drawing section withdrawn fluid in each port, thus according to some realities
Mode is applied, the flow for being injected into drawing section or the fluid extracted from drawing section can be zero.According to other embodiment, injection
Can be identical with baseline fluid flow to the flow for drawing section or the fluid extracted from drawing section.In some embodiments,
It is injected into and draws section and either may be about 2 times, 3 times of baseline fluid flow or even from the flow for drawing the fluid that section extracts
4 times.In some embodiments, it is injected into and draws section or may be about baseline fluid from the flow for drawing the fluid that section extracts
5 times, 6 times or even 7 times of flow.In other embodiments, it is injected into the fluid for drawing section or being extracted from drawing section
Flow may be about 8 times, 9 times or even 10 times of baseline fluid flow.In other embodiments, it is injected into drawing section
11 times, 12 times or even 13 times of baseline fluid flow are either may be about from the flow for drawing the fluid that section extracts.At it
In his embodiment, it is injected into and draws section or may be about the 14 of baseline fluid flow from the flow for drawing the fluid that section extracts
Again, 15 times or even 16 times.In some embodiments, it is injected into and draws section or the flow from the fluid for drawing section extraction
It may be about 17 times or even 18 times of baseline fluid flow.
Once it is determined that be used for from draw section withdrawn fluid or inject fluid into draw the port in section quantity and
Position, it can measure at each port due to the actual change of the temperature curve of glass caused by fluid injection and fluid extraction
Change.For example, in embodiment of the section with 3 ports is drawn, stream can be injected with certain flow in a port
Body, certain flow are only up to enough to measure the influence that the injection flow changes for temperature curve.Similarly, by fluid
Individually it is injected into second port and the 3rd port and (that is, once only injects fluid into a port), injection flow is only
Only up to it is enough to measure the influence that the injection flow changes for temperature curve.Injection from 7 PORT IMPLEMENTATIONs is obtained
