Description

Technical Field

[0001] This utility model relates to the field of coupler packaging technology, and more specifically, to a packaging device for a polarization-maintaining fiber coupler. Background Technology

[0002] Polarization-maintaining fiber couplers are key components for achieving coupling, splitting, and multiplexing of linearly polarized light. Their most significant characteristic is their ability to stably transmit two orthogonally polarized beams while maintaining their respective polarization states, making them crucial optical devices for various military interferometric sensors, coherent optical communications, fiber optic gyroscopes, and fiber optic hydrophones.

[0003] Chinese patent CN 221148964 U relates to the field of optoelectronic device manufacturing technology, and particularly to a packaging device for a polarization-maintaining fiber optic coupler. The device includes a body housing an ultraviolet lamp, and a first motor fixedly mounted on the body. A ball screw is fixedly connected to the output of the first motor. This invention utilizes a ball screw and nut mechanism to drive a mounting box to move horizontally, thereby adjusting the horizontal position of the ultraviolet lamp. Furthermore, the meshing of a driven rack and an incomplete gear allows the reciprocating motion of the driven rack to drive the incomplete gear to deflect. This deflection of the incomplete gear, through a connecting rod, causes the ultraviolet lamp to deflect at an angle, thus adjusting the irradiation angle of the ultraviolet lamp. Compared to the fixed installation of the ultraviolet lamp in existing technologies, this solution improves the irradiation effect of the ultraviolet lamp by adjusting its horizontal position and irradiation angle.

[0004] Although the aforementioned patent can adjust the horizontal position and irradiation angle of the ultraviolet lamp to improve the irradiation effect, the ultraviolet rays emitted by it will damage human skin due to the lack of protective mechanisms during use. If they shine directly into the eyes, they will also damage the workers' eyesight. Utility Model Content

[0011] The clamping mechanism includes four electric push rods, the fixed ends of which are inserted into the inner wall of the rotating cylinder, and the telescopic ends of which are fixedly connected to clamping plates.

[0012] As a further description of the above technical solution:

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0025] Please see Figure 1-4In this utility model: a packaging device for a polarization-maintaining fiber optic coupler includes a worktable 1, a rotating plate 2 rotatably connected to the top of the worktable 1, a motor 3 fixedly connected to the bottom of the worktable 1, the output shaft of the motor 3 fixedly connected to the rotating plate 2, two mounting plates 4 fixedly connected to the top of the rotating plate 2, each mounting plate 4 having a sliding block 5 slidably connected to its top, each mounting plate 4 having a drive mechanism 6 for moving the sliding block 5, each of the four sliding blocks 5 having a rotating cylinder 7 rotatably connected to one side, each of the four rotating cylinders 7 having a clamping mechanism 8, two motors 9 fixedly connected to the two sliding blocks 5 furthest from the motor 3, the output shafts of the two motors 9 being fixedly connected to the two rotating cylinders 7 respectively, and a bracket 10 fixedly connected to the top of the worktable 1, with an electric push rod 11 fixedly connected to the top of the bracket 10. The telescopic end of electric push rod 11 is fixedly connected to a protective cover 12. An electric push rod 2 13 is inserted through the protective cover 12 and fixedly connected to it. The telescopic end of electric push rod 2 13 is fixedly connected to a lifting block 14. An ultraviolet lamp 15 is installed at the bottom of the lifting block 14. The drive mechanism 6 includes a slide 601, which is opened on the mounting plate 4. A lead screw 602 is rotatably connected to the inner wall of the slide 601. A motor 3 603 is embedded in the top of the mounting plate 4. The output shaft of the motor 3 603 passes through the mounting plate 4 and is fixedly connected to the lead screw 602. The bottoms of the two moving blocks 5 are both sleeved on the lead screw 602 and threadedly connected to it. The clamping mechanism 8 includes four electric push rods 3 801. The fixed ends of the four electric push rods 3 801 are all inserted into the inner wall of the rotating cylinder 7. The telescopic ends of the four electric push rods 3 801 are all fixedly connected to clamping plates 802.

[0026] In this invention, the commonly available polarization-maintaining fiber couplers are mainly cylindrical. When encapsulating the cylindrical polarization-maintaining fiber coupler, one end of the coated polarization-maintaining fiber coupler is first inserted into a rotating cylinder 7. Then, the worker starts motor 603 to rotate the lead screw 602. Since the lead screw 602 is threadedly connected to two moving blocks 5 and has a double thread, the motor 603, once started, will drive the two rotating cylinders 7 to move towards each other via the lead screw 602 until the other end of the polarization-maintaining fiber coupler is also in the rotating cylinder 7. At this point, both ends of the polarization-maintaining fiber coupler are located inside the two rotating cylinders 7. Then, the electric push rods 801 in both rotating cylinders 7 are simultaneously activated. The electric push rods 801 will drive the clamping plates 802 to converge towards the center of the polarization-maintaining fiber coupler until all the clamping plates 802 are tightly against the polarization-maintaining fiber coupler, thus completing the positioning and clamping of the polarization-maintaining fiber coupler and maintaining the polarization fiber... After the coupler is positioned and clamped, the user turns on motor 3 to rotate the rotating plate 2 180 degrees. At this time, the polarization-maintaining fiber coupler will move to the bottom of the protective cover 12. Then, the electric push rod 11 is turned on to lower the protective cover 12. The bottom of the protective cover 12 will contact the rotating plate 2, thus achieving the effect of sealing the encapsulation area. Then, the electric push rod 213 is turned on to lower the lifting block 14. After the lifting block 14 lowers, it will move the ultraviolet lamp 15 toward the polarization-maintaining fiber coupler. After the ultraviolet lamp 15 moves to a suitable distance from the polarization-maintaining fiber coupler, the user turns on the ultraviolet lamp 15 to cure the adhesive on the polarization-maintaining fiber coupler. During the curing process, the worker turns on motor 29 to rotate the rotating cylinder 7 on one side. At this time, the polarization-maintaining fiber coupler will rotate, thus being evenly irradiated by the ultraviolet lamp 15, effectively improving the curing effect of the adhesive used on the polarization-maintaining fiber coupler and improving the encapsulation quality of the polarization-maintaining fiber coupler.

[0027] Please see Figure 1 The protective cover 12 has an observation port 16, and a polycarbonate plate 17 is fixedly connected to the inner wall of the observation port 16.

[0028] In this invention, the polycarbonate plate 17 has the effect of being light-transmitting but not light-transmitting, allowing users to observe the curing process without being affected by ultraviolet light, thereby improving the safety of the device.

[0029] Please see Figure 4 The clamping plate 802 is arc-shaped and has a rough surface.

[0030] In this invention, the clamping plate 802 is arranged in an arc shape, which can be adapted to the shape of the polarization-maintaining fiber coupler, thereby improving the clamping stability of the clamping plate 802 on the polarization-maintaining fiber coupler.

[0031] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
