Description
Technical field
The present invention relates to technical field of optical fiber, particularly relate to device for stripping and the method for a kind of preform loose media.
Background technology
Utilizing OVD legal system to make preform, its principle is gaseous halide to be carried out instead with oxyhydrogen flame or methane flame
Should, produce substantial amounts of silicon dioxide " dust " granule, along with moving back and forth of plug, be in layer deposited on the appearance of plug
Face, after having deposited, then is sintered vitrification, thus prepares preform.It produces schematic diagram as shown in Figure 1: its
The blowtorch 3 of middle halogenation can produce substantial amounts of silicon dioxide " dust " granule, and plug 1 is fixed on equipment, it is possible to rotation, and
Moving left and right, the loose media 2 of dust is deposited on plug 1.
If unit exception occurs in the fabrication process, the emergency situations such as raw material is abnormal, whole preform loose media
To scrap.In order to retrieve partial loss, needing to divest the loose media 2 of dust, retain plug 1 therein, then carry out must for plug 1
The process wanted, is reused for producing.Owing to preform loose media uses blowtorch deposition, the density of its loose media is relatively big, energy
Enough reach 0.5g/cm3, the loose media of preform loose media is close to vitrification, thus causes loose media to divest difficulty.
In prior art, need artificial axe to be divested by preform loose media to off-chip rod about 5mm place, then make
Rinse mandrel loose body surface with pure water, utilize the temperature jump of loose media, the loose media of innermost layer is popped.Workman uses
Prefabricated rods loose media is divested by axe, owing to the density of preform loose media is relatively big, time-consuming the when of divesting, arduously, from
And cause labor strength big, and divest inefficient.
Summary of the invention
In order to reduce the labor intensity of workman, that improves prefabricated rods loose media divests efficiency, it is proposed that preform
The process for stripping of loose media and device.
The process for stripping of the application and device can be applicable to the preform loose media of needles of various sizes, are particularly well-suited to
Large-sized preform loose media, because large-scale optical fiber prefabricating stick loose media quality is big, overburden amount is big, by artificial stripping
From time labor intensity big especially, process for stripping and device by the application can effectively reduce labor intensity, improve and divest effect
Rate.
The technical scheme that the present invention takes is as follows:
The process for stripping of a kind of preform loose media, comprises the following steps:
1) the failed preform loose media of deposition is cooled；
2) the preform loose media after cooling is put into placement platform；
3) control exploitation cylinder repeatedly to move, move from one end of preform loose media to the other end, exploit cylinder
After often completing once to move, the piston rod of exploitation cylinder drives cutting edge motion, once shells the loose media outside plug
From process；
4) regulation is exploited the position of cylinder or rotates preform loose media, repeats step 3)；
5) step 4 is repeated) until the minimum range between loose media and plug is within the specified range；
6) loose media outside plug is carried out instantaneous temperature reduction, make loose media blow at plug；
7) after plug cools down, plug is carried out acid etching.
Considering the hardness of loose media, this method cutting edge is driven by exploitation cylinder, it is possible to the most quickly to loose media
Peel off；Cutting edge is driven by exploiting cylinder, can regulate cutting force by controlling the pressure of exploitation cylinder；Predispersed fiber can be made
System rod loose media is automatically cut off, and alleviates the labor intensity of workman.
Optionally, described step 3) in, when exploiting cylinder and carrying out lift-off processing, by detent mechanism by preform
Loose media is fixed.
Preform loose media can be fixed by detent mechanism, prevent exploiting cylinder and carrying out lift-off processing
Time, preform loose media moves, and affects stripping operation.
During practice, detent mechanism can fix preform loose media always, or solid when lift-off processing
Surely preform loose media is lived.
Optionally, after 4 step 3), the loose media on preform loose media is rectangular-shaped, now completes
Once circumference divests operation；
Operation is divested so that the minimum range between loose media and plug is within the specified range by circumference at least one times.
Rectangular-shaped in order to make preform loose media peel off into, first face can be cut when first time；Second
Time secondary, mobile exploitation cylinder, second face that cutting is oppositely arranged with first face；Time for the third time, preform is loose
Body rotates 90 °, cuts the 3rd face；When the 4th time, preform loose media is rotated 180 °, cuts the 4th face.
Except the most this cutting form, it is also possible to for: time for the first time, cut first face；Time for the second time, by predispersed fiber
System rod loose media rotates clockwise 90 °, then second face of cutting；Time for the third time, preform loose media is turned clockwise
Dynamic 90 °, then the 3rd face of cutting；When the 4th time, preform loose media is rotated clockwise 90 °, then cutting the 4th
Individual face.
The second cutting form can also replace to rotate counterclockwise 90 ° by rotating clockwise 90 ° above.
Except cutting process above, during practice, cutting order can be selected as required and rotate accordingly
Angle.
Optionally, described step 5) in appointment scope be: 3～10mm.
Optionally, often complete after once circumference divests operation, the position of regulation exploitation cylinder, make exploitation cylinder away from mandrel axis
The horizontal range of line diminishes.
Operation is divested, it is possible to reduce overburden amount during each strip operation, it is possible to reduce exploitation cylinder by repeatedly circumference
With the working strength of cutting edge, thus ensure peel off reliability and peeling effect.
Optionally, described step 1) in, cool depositing failed preform loose media to 180 DEG C～250
℃；Carrying out described step 6) before, preform loose media is cooled to 130 DEG C～160 DEG C.
Optionally, step 6) in instantaneous temperature reduction operational approach as follows: pure to 5 ° of C of loose media surface washing～20 DEG C
Water.
In order to ensure the uniformity of strip operation, described step 3) in, exploitation cylinder moves same distance every time.
Described step 7) after plug carries out acid etching, use deionized water rinsing plug, and be dried.
