Problems solved by technology

But in practical application, it is very difficult to determine the cutting angle of the cylinder without cutting; on the other hand, the rod diameter range of the butt joint part of this patent is only 35mm~55mm, which becomes inapplicable under the trend of increasing rod diameter Furthermore, after practice, when there is a cutting angle at one end of the butt joint, although there is no air bubble remaining during the butt joint process, there are extruded protrusions and depressions, which affect the stress of the butt joint

Embodiment 1

[0052] Example 1: Axial vapor deposition method (VAD) is used to deposit a powdery mandrel, and after dehydroxylation vitrification, a prefabricated rod with a diameter of 80 mm is formed. The preformed rod with a diameter of 80 mm is connected to a tail with a diameter of 80 mm by using the present invention. Handle for easy follow-up production.

[0053] In this embodiment, θ is 5°, d=80*tan5°=7.00mm, D=2d / 3=4.67mm, according to Figure 2(a), use a cutting machine to cut the preform 1, so that the preform cut end face 11 and The axis 4 is vertical; use a cutting machine to cut the tail handle 2 so that the end face 21 forms an angle of 5° with the centerline 5 of the blowtorch.

[0054] The preform rod 1 and the tail handle 2 start to rotate at a speed of 10rpm, the blowtorch 3 is ignited and burned, and the H 2 The flow rate is 300L / min, the inner O 2 Flow rate is 50 L / min, external O 2 The flow rate is 100 L / min. After burning for 8 minutes, the preform master rod 1 and ...

Embodiment 2

[0057] Embodiment 2: Axial vapor deposition method (VAD) is used to deposit a powder core rod, and a preform rod with a diameter of 50 mm is generated through dehydration vitrification, and the preform rod with a diameter of 50 mm is connected to a tail with a diameter of 50 mm by using the present invention. Handle for easy follow-up production.

[0058] In this embodiment, θ is 8°, d=50*tan8°=7.03mm, D=2d / 3=4.69mm, according to Figure 2(a), use a cutting machine to cut the preform 1, so that the preform cut end face 11 and The axis 4 is vertical; use a cutting machine to cut the tail handle 2 so that the cut end face 21 of the tail handle forms an 8° angle with the centerline 5 of the blowtorch.

[0059] The preform rod 1 and the tail handle 2 start to rotate at a speed of 10rpm, the blowtorch 3 is ignited and burned, and the H 2 Flow rate is 250L / min, inner O 2 Flow rate is 40 L / min, external O 2 The flow rate is 85 L / min. After burning for 6 minutes, the preform master ...

Description

technical field [0001] The patent of the present invention relates to a manufacturing method and device for butt jointing of an optical fiber preform rod and a tail handle, using the method and the device for butt jointing of an optical fiber preform rod and a tail handle. Background technique [0002] The manufacture of optical fiber and optical fiber preform is basically carried out according to the following process: the core rod in powder state is deposited by axial vapor deposition method (VAD), and the core rod in glass state is formed by dehydroxylation vitrification; then it is extended into a thinner core rod of appropriate length Rods are further coated with powdered rods around the periphery of each mandrel, and dehydroxylated and vitrified again to form large-sized preformed rods. [0003] In the manufacturing process of the optical fiber preform, the base material of the optical fiber preform needs a tail handle for support, so the butt joint between the base ma...
