Description

Technical Field

[0001] The present invention relates to the technical field of coupled optical fibers, and in particular to a device and method for manufacturing MT optical coupling of glass materials. Background Art

[0002] At present, the combination of optical fiber and semiconductor laser has made semiconductor lasers more widely used. However, in the field of communications, how to make the output light of the laser more stable and transmit over longer distances, and how to make the output light power of the semiconductor laser more effectively transmitted to the laser gain medium in pumping solid-state lasers to obtain higher pumping efficiency, all involve the coupling problem of semiconductor lasers and optical fibers.

[0003] When making an MT-type optical fiber coupler, it is necessary to first peel off the protective layer of the head end of the optical fiber body to expose it to form a bare end, and then apply glue to the glue-coated area on the bare end and insert the whole into the glass ferrule. After the glue is cured, it is necessary to insert the ferrule seat into the glass ferrule, and the optical fiber body is located in the ferrule seat to complete the production of the coupled optical fiber. However, the insertion operation of the optical fiber body and the ferrule seat is relatively troublesome and difficult to be completed in the same device, resulting in low work efficiency. At the same time, after the coupled optical fiber is produced, the surface will easily have certain residues or impurities, and it is difficult for existing devices to process them in time, which affects the transmission efficiency and quality of subsequent optical signals and has low practicality.

A core seat 42 is arranged between the two blocks 18 above the lower plate 10, an optical fiber body 41 is arranged between the two blocks 18 below the lower plate 10, and an exposed end 44 is arranged at the bottom of the optical fiber body 41.

[0038] A method for manufacturing MT optical coupling of glass material, comprising the following steps:

[0039] In the first step, the two knobs 22 on the lower plate 10 are rotated to make the two stoppers 18 on the lower plate 10 close to each other to fix the ferrule seat 42, and the two knobs 22 on the lower plate 10 are rotated to make the two stoppers 18 on the lower plate 10 close to each other to fix the optical fiber body 41, and glue is applied to the glue-coated area on the exposed end 44 on the lower side of the optical fiber body 41, and the glass ferrule 43 is inserted into the insertion hole 12;

[0040] In the second step, the upper plate 4 and the lower plate 10 are synchronously moved downward by the multi-stage cylinder 5 until the first functional cylinder 11 and the second functional cylinder 16 respectively abut against the two vertical blocks 45, so that the exposed end 44 of the optical fiber body 41 is inserted into the glass ferrule 43, and the lower end of the exposed end 44 protrudes a distance from the bottom of the glass ferrule 43, and the glue on the exposed end 44 is cured by the heating block 34;

[0041] In the third step, the upper plate 4 is moved close to the lower plate 10 by the multi-stage cylinder 5, and the ferrule seat 42 is inserted into the glass ferrule 43 by moving the assembly, and the optical fiber body 41 is located in the ferrule seat 42, so that the production of the coupled optical fiber is completed, and the two stop blocks 18 above and below the lower plate 10 are moved away from each other by turning the four knobs 22;

[0042] In the fourth step, the upper plate 4 and the lower plate 10 are moved upward by the multi-stage cylinder 5, and the mold base 3 and the coupled optical fiber in the mold base 3 are rotated synchronously by setting a rotating component and a cleaning component, and the surface of the coupled optical fiber is cleaned to reduce the residue on the surface.

[0043] When the present invention is used, the two knobs 22 above the lower plate 10 are rotated to make the two abutting blocks 18 above the lower plate 10 close to each other to fix the ferrule seat 42, and the two knobs 22 below the lower plate 10 are rotated to make the two abutting blocks 18 below the lower plate 10 close to each other to fix the optical fiber body 41, and glue is applied to the glue-coated area on the exposed end 44 below the optical fiber body 41, and the glass ferrule 43 is inserted into the insertion hole 12, and then the multi-stage cylinder 5 is started to move the upper plate 4 downward. Since the first spring 21 is fixedly connected between the upper plate 4 and the lower plate 10, the upper plate 4 and the lower plate 10 are in the initial state. In the state, the upper plate 4 and the lower plate 10 will move downward synchronously. During the process of the upper plate 4 and the lower plate 10 moving downward synchronously until the first functional tube 11 and the second functional tube 16 respectively abut against the tops of the two vertical blocks 45, the exposed end 44 of the fixed optical fiber body 41 will be inserted into the glass ferrule 43, and the lower end of the exposed end 44 will protrude a distance from the bottom of the glass ferrule 43, that is, the lower end of the exposed end 44 will enter the extension hole 36. After the exposed end 44 of the optical fiber body 41 is inserted into the glass ferrule 43, the glue on the exposed end 44 is cured by the heating block 34 to achieve the fixation of the two.

[0044] After the glue is solidified, the upper plate 4 is moved downward for a certain distance by the multi-stage cylinder 5. During this process, the first functional cylinder 11 and the second functional cylinder 16 are respectively against the tops of the two vertical blocks 45, and the lower plate 10 cannot continue to move downward, so that the upper plate 4 gradually approaches the lower plate 10. The first spring 21 is compressed. When the upper plate 4 approaches the lower plate 10, the lower moving block 8 and the fixed ferrule seat 42 continue to move downward. The lower moving block 8 moves downward, and the inclined surface of the lower moving block 8 is aligned with the inclined surface of the auxiliary groove 27 on the displacement block 26. The surfaces cooperate with each other, so that the two displacement blocks 26 move away from each other, the second spring 29 is compressed, and the two displacement blocks 26 move away from each other, which will cause the two retaining blocks 18 below the lower plate 10 to move away from each other, so that the fixed core seat 42 can be inserted into the glass core seat 43 later, and the optical fiber body 41 is located in the core seat 42, completing the production of the coupled optical fiber, and then by turning the knob 22, the two retaining blocks 18 above and below the lower plate 10 are moved away from each other, and the fixation of the core seat 42 is released to avoid affecting subsequent operations.

[0045] When the upper plate 4 approaches the lower plate 10, the two connecting rods 20 are provided so that the first functional plug 39 and the second functional plug 40 can move downward synchronously. The downward movement of the first functional plug 39 causes the incompressible liquid in the first functional cylinder 11 to be squeezed into the lower cylinder 14 through the first connecting pipe 13, thereby causing the rectangular plug 32 and the round rod 31 to move upward. Since the rectangular plug 32 does not rotate, and the rotating block 37 in the rotating tube 15 is located on the rotating groove 38 on the outer wall of the round rod 31, during the upward movement of the round rod 31, its rotating block 37 will slide in the spiral rotating groove 38, thereby causing the rotating tube 15 to rotate multiple times in one direction. The rotation of the rotating tube 15 will drive the inner ring of the one-way bearing 30 to rotate, but at this time, the inner ring and outer ring of the one-way bearing 30 will rotate idly, and the outer ring of the one-way bearing 30 and the mold base 3 will not rotate. The downward movement of the second functional plug 40 will produce an extrusion effect, thereby causing the gas in the second functional cylinder 16 to be squeezed into the collecting box 17 through the third connecting pipe 25.

[0046] After the production of the combined optical fiber is completed, the upper plate 4 is moved upward by the multi-stage cylinder 5. In the first stage, due to the elastic force generated by the compression of the first spring 21, the first functional cylinder 11 and the second functional cylinder 16 are still respectively against the tops of the two vertical blocks 45, and the lower plate 10 does not move. The upper plate 4 gradually moves away from the lower plate 10, and the first spring 21 gradually extends. By setting the connecting rod 20, the first functional plug 39 and the second functional plug 40 can be moved upward. During the upward movement of the first functional plug 39, the incompressible liquid in the lower cylinder 14 will be sucked into the first functional cylinder 11 through the first connecting pipe 13, and the rectangular plug 32 and the round rod 31 will move downward, and the rotating block 37 will slide in the spiral rotating groove 38, thereby causing the rotating tube 15 to rotate multiple times in the other direction. At this time, the inner ring and the outer ring of the one-way bearing 30 The outer ring of the one-way bearing 30, the mold base 3 and the coupled optical fiber made in the mold base 3 rotate multiple times accordingly. During the upward movement of the second functional plug 40, a suction effect is generated, so that during the rotation of the manufactured coupled optical fiber, its surface is evenly vacuumed to keep the surface clean, thereby improving the transmission efficiency and quality of subsequent optical signals. During the process of the upper plate 4 moving away from the lower plate 10, the downward block 8 moves upward, and the inclined surface on the downward block 8 will no longer cooperate with the inclined surface of the auxiliary groove 27 on the displacement block 26. The elastic force generated by the compression of the second spring 29 can make the two displacement blocks 26 approach each other and return to the initial position. When the first spring 21 restores its original length, the upper plate 4 and the lower plate 10 will move upward synchronously until they return to the initial position. Finally, the coupled glass ferrule 43 and the ferrule seat 42 can be removed.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
