Description

Technical Field

[0001] The utility model relates to the technical field of taper drawing machines, in particular to an optical fiber taper drawing mechanism. Background Art

[0002] Optical fiber, short for optical fiber, is a fiber made of glass or plastic that conducts light. The fused taper manufacturing process involves bringing two (or more) uncoated single-mode (or multimode) optical fibers together in a specific pattern, heating and melting them at high temperatures, and simultaneously stretching them in both directions to form a bidirectional tapered structure, thus enabling the manufacture of optical fiber devices. The equipment used to manufacture fused tapers for optical fiber devices is a fused taper machine.

[0003] During the melt taper drawing process, the molten area needs to be heated and stretched to both sides. How to form the required conical structure during the taper drawing process is the most critical technology of the taper drawing mechanism. This requires that the stretching process and the heating components in the taper drawing process can be precisely coordinated. At present, the taper drawing mechanism of the melt taper drawing machine has poor performance. Utility Model Content

[0005] The utility model is realized through the following technical scheme, which provides an optical fiber taper mechanism, including a taper pulling bidirectional slide and a fire head module located on one side of the taper pulling bidirectional slide, the two sliders of the taper pulling bidirectional slide are each equipped with a clamping module, the clamping module includes an optical fiber clamping seat and a clamping bidirectional slide, the upper end face of the optical fiber clamping seat is provided with a V-shaped groove, an exhaust cavity connected to an exhaust pipe is provided in the optical fiber clamping seat, the bottom of the V-shaped groove is provided with an adsorption hole connected to the exhaust cavity, the optical fiber clamping seat is located between the two sliders of the clamping bidirectional slide, and coaxial ceramic rods are fixed to the two sliders of the clamping bidirectional slide.

[0006] In this solution, two optical fibers are placed side by side in two V-grooves. The optical fibers are adsorbed and clamped by suction through the adsorption holes. The two optical fibers are clamped by the ends of the ceramic rod to achieve close contact between the two optical fibers. The two sliders of the taper bidirectional slide move in opposite directions. The distance between the two clamping modules is increased to achieve molten taper. At the same time, the fire head module heats the molten position.

[0007] As an optimization, a cutting cylinder is mounted on one of the sliders of the tapered bidirectional slide, extending radially along the slide. A fiber cutting module is mounted on the cylinder's telescopic axis. In this solution, the cutting cylinder drives the fiber cutting module toward the optical fiber, where it removes any excess fiber.

A burner bracket, extending between the two clamping modules, is affixed to the slider of the burner lift slide. The burner bracket is mounted on the burner bracket.

The burner translation slide adjusts the burner's position along the length of the optical fibers, and the burner lift slide adjusts the burner's vertical position, enabling heating of different areas to achieve the desired effect in the melted areas.

[0010] As an optimization, a ceramic rod mounting seat is fixedly connected to the slider of the clamping bidirectional slide, and the ceramic rod is pressed on the ceramic rod mounting seat by screws. In this solution, the ceramic rod is pressed on the ceramic rod mounting seat by screws, thereby facilitating the disassembly and assembly of the ceramic rod.

[0011] As an optimization, the ceramic rod is a round rod with a diameter of 0.3-1.5 mm, which occupies a small space and can meet the requirements of clamping the optical fiber end.

[0012] As an optimization, the ceramic rod is located between the two optical fiber clamping blocks, thereby reducing the distance between the ceramic rods of the two clamping modules and making them closer to the melting area.

[0013] The beneficial effects of the present invention are as follows: the present invention provides an optical fiber taper mechanism, in which optical fibers are placed side by side in two V-grooves, and the optical fibers are adsorbed and clamped by suction through the adsorption holes, and the two optical fibers are clamped by the ends of the ceramic rods to achieve close contact between the two optical fibers.

[0024] In order to clearly illustrate the technical features of this solution, this solution is described below through specific implementation methods.

[0025] like Figures 1 to 8 As shown, the utility model is a fiber optic taper mechanism, comprising a taper bidirectional slide 1 and a fire head module 3 located on one side of the taper bidirectional slide 1. The taper bidirectional slide 1 is an electric bidirectional slide, which is driven by a motor to rotate the forward and reverse screws to achieve relative movement of the two sliders on the horizontal plane.

[0026] The two sliders of the tapered bidirectional slide 1 are both equipped with clamping modules 2, and the two clamping modules 2 are symmetrically arranged. Figure 5-7 As shown, the clamping module 2 includes a fiber clamping seat 22 and a clamping bidirectional slide 21. In this embodiment, a clamping module mounting plate is fixedly connected to the slider of the tapered bidirectional slide 1, and the fiber clamping seat 22 and the clamping bidirectional slide 21 are both fixed on the clamping module mounting plate.

[0027] The upper end surface of the optical fiber clamping seat 22 is a plane, and a V-shaped groove is formed on the upper end surface of the optical fiber clamping seat 22. The V-shaped grooves of the two optical fiber clamping seats 22 are coplanar, and each optical fiber is supported in two V-shaped grooves.

[0028] An air pumping cavity connected to the air pumping pipe is provided in the optical fiber clamping seat 22, and an adsorption hole 25 connected to the air pumping cavity is opened at the bottom of the V-shaped groove, so that the optical fiber is adsorbed on the bottom of the V-shaped groove by vacuuming.

[0029] The fiber clamping block 22 is located between the two sliders holding the bidirectional slide 21. A coaxial ceramic rod 24 is fixed to each slider. Positioning the ceramic rod 24 between the two fiber clamping blocks 22 reduces the distance between the ceramic rods of the two clamping modules, bringing them closer to the melting zone. The ceramic rod 24 is a round rod with a diameter of 0.3-1.5 mm.

[0030] A ceramic rod mounting seat 23 is fixedly connected to the slider of the clamping bidirectional slide 21 , and the ceramic rod 24 is pressed against the ceramic rod mounting seat 23 by screws, so that the ceramic rod 24 can be easily assembled and disassembled.

[0031] like Figure 8 As shown, the fire head module 3 includes a fire head translation slide 31, a fire head feed slide 32, and a fire head lifting slide 33, which are connected in series. The fire head translation slide 31, the fire head feed slide 32, and the fire head lifting slide 33 are all electric slides. The slider of the fire head translation slide 31 moves in a direction parallel to the movement direction of the taper bidirectional slide 1, the slider of the fire head feed slide 32 moves in a direction parallel and perpendicular to the movement direction of the taper bidirectional slide 1, and the slider of the fire head lifting slide 33 moves vertically. Specifically, the fire head feed slide 32 is fixed to the slider of the fire head translation slide 31, and the fire head lifting slide 33 is fixed to the slider of the fire head feed slide 32.

[0032] A burner bracket 35 extending between the two clamping modules 2 is fixedly connected to the slider of the burner lifting slide 33, and a burner 34 is mounted on the burner bracket 35. The burner 34 is connected to the hydrogen tank and is heated by hydrogen combustion.

[0033] A cutting cylinder 5 is mounted on one of the sliders of the tapered bidirectional slide 1, which is telescopic along the radial direction of the tapered bidirectional slide 1. The cutting cylinder 5 is a slide cylinder, and a fiber cutting module 4 is mounted on the telescopic axis of the cutting cylinder 5. The fiber cutting module 4 is a pneumatic scissor used to cut off excess optical fiber.

[0034] The use method of this utility model:

[0035] When in use, two optical fibers are placed side by side in two V-shaped grooves, and the optical fibers are adsorbed and clamped by suction through the adsorption holes 25. The cutting cylinder 5 drives the optical fiber cutting module 4 to move toward the optical fiber, and the optical fiber cutting module 4 cuts off the excess optical fiber that needs to be cut.

[0036] The burner feed slide 32 drives the burner 34 to the area where the two optical fibers are to be melted. The two-way clamping slide 21 drives the two ceramic rods 24 to move relative to each other, clamping the two optical fibers together through the ends of the ceramic rods 24 to achieve close contact between the two optical fibers. The burner 34 is turned on, heating the melting area through hydrogen combustion. Simultaneously, the two sliders of the taper bidirectional slide 1 move in opposite directions, and the distance between the two clamping modules 2 increases to achieve melting and taper. The burner translation slide 31 can adjust the burner's position along the length of the optical fiber, and the burner lifting slide 33 can adjust the burner's vertical position.
