Technical Field

[0001] This utility model relates to the field of optical fiber processing, and in particular to an optical fiber array end face polishing device. Background Technology

[0002] The end face of an optical fiber array refers to the end surface of the optical fiber in the optical fiber array, that is, the part of the optical fiber array that is connected or coupled to optical devices or other optical fiber arrays.

[0003] The fiber array fabrication process involves placing the bare fiber portion, after the fiber coating has been removed, into a V-groove, pressurizing it with a pressurizing device, bonding it with an adhesive, and finally grinding and polishing the surface to the required precision.

[0004] End face grinding is a delicate process that involves four key steps: rough grinding, grinding, fine grinding, and polishing. Each step uses sandpaper with different grit sizes to ensure that the roughness of the end face is gradually reduced, ultimately achieving the desired smoothness.

[0005] Existing equipment requires changing sandpaper or machines to meet different grinding processes, which is cumbersome, time-consuming, and labor-intensive, affecting grinding efficiency. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0035] The following will refer to the appendix. Figures 1 to 6 The present invention will be described in detail with reference to the embodiments.

[0036] Overall, this utility model relates to a fiber optic array end face polishing device, including a bottom shell 1, a mounting base 2 fixedly disposed on the top of the bottom shell 1, a polishing component 3 fixedly disposed on the bottom surface of the mounting base 2, a top cover 4 disposed on the top of the mounting base 2, an inner groove 401 formed on the top cover 4, sliding grooves 405 formed on two opposite sides of the inner groove 401, and a mounting component slidably connected in the sliding grooves 405 on both sides by a slider 404. A motor 304 is provided inside the bottom shell 1, and the end of the output shaft of the motor 304 extends into the mounting base 2 and is fixedly connected to the bottom surface of the polishing component 33. The polishing component 3 is below the inner groove 401.

[0037] In this embodiment, the bottom shell 1 serves as the basic support structure of the entire device, located at the bottom to provide stable support for other components; the mounting base 2 is used to install and support the polishing assembly 3, ensuring that the polishing assembly 3 can operate stably; the top cover 4 is used to enclose and protect the polishing area, blocking external interference factors; the mounting assembly is used to fix the V-groove, fixing the exposed end face of the fiber array above the polishing assembly 3, and the motor 304 drives the polishing assembly 3 to polish the end of the fiber array. The mounting assembly can slide within the slide groove 405 via the slider 404, adjusting the position of the mounting assembly in the inner groove 401.

[0038] Among them, such as Figure 2 As shown, the grinding assembly 3 includes a first mounting groove 301, a second mounting groove 302, and a third mounting groove 303. The second mounting groove 302 is fixedly disposed on the periphery of the first mounting groove 301, and the third mounting groove 303 is fixedly disposed on the periphery of the second mounting groove 302. Sandpaper with different particle sizes is fixedly disposed in the first mounting groove 301, the second mounting groove 302, and the third mounting groove 303, respectively.

[0039] In practice, by adjusting the position of the mounting components within the inner groove 401, the ends of the fiber array can be switched between different positions of the polishing components 3, namely the first mounting groove 301, the second mounting groove 302, and the third mounting groove 303, to meet the polishing requirements of different particle sizes.

[0040] In addition, such as Figure 3 and Figure 4 As shown, the above-mentioned mounting components include a connecting block 402 and a mounting cylinder 403. The mounting cylinder 403 is fixedly disposed inside the connecting block 402, and the connecting block 402 is rotatably disposed between the two side sliders 404.

[0041] In practice, the bonded V-groove is placed inside the mounting cylinder 403 for fixation. During grinding, the angle of the mounting cylinder 403 on the grinding assembly 3 can be adjusted by rotating the connecting block 402 to meet different working requirements. The adjusted mounting cylinder 403 is limited by the friction between the connecting block 402 and the slider 404.

[0042] It should be noted that, in order to prevent the V-groove inside the mounting cylinder 403 from falling off during grinding and affecting the grinding process, in this embodiment, as... Figure 4As shown, a clamping assembly is provided inside the mounting cylinder 403. The clamping assembly includes clamping plates 5 symmetrically arranged on two opposite sides inside the mounting cylinder 403. The top end of the clamping plate 5 is hinged to the inner wall of the mounting cylinder 403, and the bottom end of the clamping plate 5 extends towards the bottom of the mounting cylinder 403 and gradually moves away from the inner wall of the mounting cylinder 403. A spring 502 is also provided at a lower position between the clamping plate 5 and the inner wall of the mounting cylinder 403. One end of the spring 502 is movably connected to the inner wall of the mounting cylinder 403, and the other end is movably connected to the clamping plate 5.

[0043] In practice, after the V-shaped groove is placed inside the mounting cylinder 403, it will compress the clamping plates 5 on both sides. This will cause the spring 502 to compress, and the force of the spring 502 returning to its original position will drive the clamping plates 5 to clamp the V-shaped groove located in the middle, thereby fixing it in place.

[0044] It should be further explained that, in order to increase the friction between the clamping plate 5 and the V-groove, in this embodiment, multiple friction blocks 501 made of soft rubber are fixedly provided at intervals on one side of the clamping plates 5 on both sides. This ensures that the V-groove is firmly clamped between the clamping plates 5 on both sides, while also preventing damage to the V-groove.

[0045] To facilitate the cleanliness of the fiber optic array inside the mounting cylinder 403 and the polishing area of ​​the polishing assembly 3 after switching positions, such as Figure 5 As shown, in this embodiment, the mounting base 2 is also provided with a cleaning component. The cleaning component includes a sliding plate 6 with its two ends slidably connected to two opposite sides of the mounting base 2, a cleaning layer 601 fixedly disposed on the top surface of the sliding plate 6, and a brush 602 fixedly disposed on the bottom surface of the sliding plate 6.

[0046] When cleaning is required, the sliding plate 6 is driven to slide within the mounting base 2. The cleaning layer 601 contacts the bottom of the mounting cylinder 403, sweeping away the polishing dust adhering to the end face of the fiber array. Meanwhile, the brush 602 on the bottom surface of the sliding plate 6 cleans the top surface of the polishing assembly 3 below. As the sliding plate 6 slides repeatedly, the cleaning layer 601 and the brush 602 clean the fiber end face and the polishing assembly 3, ensuring the cleanliness of the polishing area and guaranteeing the normal operation of the polishing work.

[0047] Preferably, in this embodiment, the cleaning layer 601 is made of cotton cloth. Furthermore, to facilitate easier operation of the sliding plate 6 by the operator, in this embodiment, one end of the sliding plate 6 extends to the outside of the mounting base 2 and is fixedly provided with an extension rod 603. The operator can slide the sliding plate 6 by moving the extension rod 603.

[0048] It should be understood that during the polishing of fiber optic arrays, a downward pressure is required to smooth the adhesive or rough surface of the cross-section. In actual operation, to facilitate the application of pressure, in this embodiment, as... Figure 3As shown, the top cover 4 and the mounting base 2 are connected by a connecting assembly, which includes an upper rod 7 and a lower rod 701. The upper rod 7 is symmetrically fixed on both sides of the mounting base 2, and the lower rod 701 is symmetrically fixed on both sides of the bottom shell 1 at the upper position and corresponds to the upper rod 7. A sliding post 703 is provided between the upper rod 7 and the lower rod 701. The top end of the sliding post 703 is fixedly connected to the upper rod 7, and the bottom end is slidably connected to the lower rod 701.

[0049] In practice, the operator applies downward pressure to the top cover 4, causing the sliding column 703 to slide within the lower rod 701. Preferably, the lower rod 701 is detachably connected to the mounting base 2 via a fixing nut 702, facilitating the operator to replace different grinding components 33.

[0050] Based on the above configuration, a tension spring 704 is fitted onto the sliding column 703. One end of the tension spring 704 is fixedly connected to the upper rod 7, and the other end is fixedly connected to the lower rod 701. The tension of the tension spring 704 drives the top cover 4 to apply downward pressure, saving manual operation.

[0051] Furthermore, in this embodiment, such as Figure 2 and Figure 6 As shown, the mounting base 2 is also equipped with a dust collection component, which includes a dust collection hood 801 disposed in the mounting base 2 and a vacuum cleaner 8 fixedly disposed in the bottom shell 1. The dust collection hood 801 and the vacuum cleaner 8 are connected.

[0052] In practice, the dust collection component can suck away the grinding dust generated during grinding, ensuring the cleanliness of the grinding area. It should be understood that the vacuum cleaner 8 can refer to existing vacuum cleaners. Its working principle is to use the internal motor to drive the blades to rotate at high speed, generate negative air pressure, and suck up dust.

[0053] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
