Description

Technical Field

[0001] The utility model relates to the technical field of optical communication, in particular to a polarization-maintaining optical fiber array debugging device. Background Art

[0002] Polarization-maintaining optical fiber transmits linearly polarized light and is widely used in various fields of the national economy, such as aerospace, aviation, navigation, industrial manufacturing technology, and communications. In interferometric optical fiber sensors based on optical coherence detection, the use of polarization-maintaining optical fiber can ensure that the linear polarization direction remains unchanged and improve the coherent signal-to-noise ratio to achieve high-precision measurement of physical quantities. When assembling the polarization-maintaining optical fiber array, the optical fiber needs to be rotated for cat's eye positioning.

[0003] To this end, the China Patent Network has disclosed a polarization-maintaining fiber array debugging device with application number 202121615206.7. A plurality of first accommodating grooves are arranged in parallel through the first working surface of the substrate. The first accommodating grooves are used to accommodate polarization-maintaining optical fibers. The first cover plate is used to limit the polarization-maintaining optical fibers in the first accommodating grooves. Therefore, after the polarization-maintaining optical fibers are placed in each of the first accommodating grooves, the end faces of the polarization-maintaining optical fibers can be conveniently and uniformly observed. The number of rotating shaft assemblies is not less than the number of first accommodating grooves. The rotating shaft is rotatably connected to the adjustment plate. The pressing block and the rotating shaft are used to clamp the polarization-maintaining optical fibers. After one end of a plurality of polarization-maintaining optical fibers are placed in the first accommodating grooves, the polarization-maintaining optical fibers are clamped by the pressing block and the rotating shaft. By rotating the rotating shafts one by one, the polarization axes of each polarization-maintaining optical fiber are adjusted to a suitable angle one by one. After the debugging is completed, all the polarization-maintaining optical fibers are removed by assembling the fixture. The entire adjustment device can complete the debugging of multiple polarization-maintaining optical fibers at one time. The debugging efficiency is high, and the debugging requirements can be better met.

[0032] A fan 301 is fixedly installed inside the base 5, and the fan 301 is electrically connected to the output end of the external power supply. A mounting frame 302 with a supporting function is provided on one side of the base 5. A rotating drum 304 is rotatably connected inside the mounting frame 302. A ventilation pipe 303 communicating with the inside of the base 5 is fixedly connected to one side of the rotating drum 304. A placement plate 305 is provided inside the base 5, and a heating plate is provided inside the placement plate 305. The glue can be quickly solidified by alternating between hot and cold.

[0033] The anti-damage adjustment component 2 also includes a driving motor 205, a buffer spring 207, a fixing cylinder 208 and a ball 209;

[0034] A driving motor 205 is fixedly installed on one side of the base plate 1. The driving motor 205 is electrically connected to the output end of the external power supply. The output shaft of the driving motor 205 is fixedly connected to the lead screw 202, which is convenient for driving the adjustment plate 4 to move. It is suitable for debugging polarization-maintaining optical fibers of different lengths, thereby improving the working efficiency of polarization-maintaining optical fiber debugging.

A ball 209 is rotatably connected to the interior of the fixing tube 208.

[0035] When the polarization-maintaining fiber is coupled with the waveguide, it is necessary to couple according to the azimuth angle of the polarization axis of the polarization-maintaining fiber to improve the success rate and reliability of the coupling package between the optical fiber array and the waveguide. Therefore, when making the polarization-maintaining fiber, it is necessary to accurately identify and adjust the polarization axis of the polarization-maintaining fiber to a preset angle to meet the coupling requirements of the polarization-maintaining fiber and the waveguide, wherein the preset angle is determined according to the actual situation and can be zero degrees, forty-five degrees, ninety degrees, or other angles. Before the pressing block is fixed to the rotating shaft, multiple polarization-maintaining optical fibers can be placed on the upper end surface of the adjustment plate 4, and then a single polarization-maintaining optical fiber is placed on the corresponding rotating shaft through a placement slit, and the pressing block is fixed to the corresponding rotating shaft to complete the clamping of the single polarization-maintaining optical fiber. After that, the clamping of each polarization-maintaining optical fiber is completed one by one. By setting the placement slit, the clamping of the polarization-maintaining optical fiber can be conveniently completed. After completing the debugging of the single polarization-maintaining optical fiber, tighten the fixing screw, and the fixing screw is pressed against the rotating shaft in the adjustment hole, so that the rotating shaft is fixed relative to the adjustment plate 4 to ensure Debugging effect: start the driving motor 205, the driving motor 205 drives the lead screw 202 to rotate, the lead screw 202 drives the moving block 203 and the adjusting plate 4 to move, so as to facilitate the adjustment of the distance between the base 5 and the adjusting plate 4. When the adjusting plate 4 moves, the pointer 204 moves above the measuring ruler 201, and the moving distance of the adjusting plate 4 can be observed. It is suitable for debugging polarization-maintaining optical fibers of different lengths, and improves the working efficiency of polarization-maintaining optical fiber debugging. At the same time, before the polarization-maintaining optical fiber is embedded in the rotating shaft, the surface of the polarization-maintaining optical fiber slides inside the connecting tube 206, and the ball 209 can reduce the wear on the surface of the polarization-maintaining optical fiber. At the same time, when the polarization-maintaining optical fiber vibrates, the buffer spring 207 drives the fixed tube 208 and the ball 209 to move, and adaptively protects the polarization-maintaining optical fiber, thereby improving the practical performance of the polarization-maintaining optical fiber array debugging.

[0038] After the polarization-maintaining optical fiber has been debugged, the uncovered portion of the first working surface can be used to receive glue, and the glue flows into the first receiving groove. After the glue solidifies, the first cover plate, the substrate and the polarization-maintaining optical fiber are fixed together. By making the area of ​​the first working surface larger than the area of ​​the surface of the first cover plate attached to the first working surface, it is convenient to inject glue into the first receiving groove. The material of the first cover plate is a transparent material. Therefore, when UV glue is injected into the first receiving groove, ultraviolet light can pass through the first cover plate, accelerate the solidification of the UV glue, and reduce the solidification time. The heating plate inside the placement plate 305 can heat the glue. At the same time, the fan 301 is started. The fan 301 blows the glue inside the first receiving groove through the ventilation pipe 303, the rotating drum 304 and the hair dryer 306. The alternation of hot and cold can further accelerate the watering and drying efficiency and reduce the solidification time. At the same time, the worm gear 308 can be driven to rotate by rotating the worm, and the worm gear 308 drives the rotating shaft 307 and the rotating drum 304 to rotate, thereby adjusting the blowing angles of the rotating drum 304 and the hair dryer 306, so as to facilitate flexible adjustment.
