Description

Technical Field

[0001] This utility model relates to the field of optical fiber production technology, and in particular to an optical fiber connector polishing device with automatic sandpaper replacement. Background Technology

[0002] Fiber optic connectors are an important component of fiber optic communication systems. Their main function is to ensure a stable optical connection between two or more optical fibers to minimize signal loss and reflection. They are widely used in telecommunications, data centers, local area networks, wide area networks, and other applications requiring high-speed data transmission.

[0003] During the processing of fiber optic connectors, the end face of the fiber optic connector needs to be ground to remove burrs generated during cutting, thereby improving the flatness of the fiber optic connector. The fiber optic connector grinding process consists of three steps: rough grinding, fine grinding, and polishing. During grinding, the fiber optic connector is first assembled on the corresponding grinding fixture, and different types of sandpaper are used to grind the connector according to the grinding requirements. Current fiber optic connector grinding equipment uses a roller conveyor to wind and replace the old sandpaper after grinding. However, the roller conveyor method results in low sandpaper replacement efficiency, and frequent sandpaper replacement leads to long downtime and reduced working efficiency of the grinding equipment.

[0004] Therefore, it is necessary to design a fiber optic connector polishing device that can automatically replace sandpaper. Utility Model Content

A sliding component for lifting and lowering the mounting plate 19 is set between the two guide blocks 9. A drive component for rotating the mounting plate 19 is set between the two guide blocks 9. A support block 26 is fixed to the bottom of the support platform 3 by welding. A drive motor Ⅲ 27 is installed on the support block 26 by bolt connection. A rotating platform 28 is rotatably set on the support platform 3. The rotating platform 28 passes through the support platform 3. The output shaft of the rotating platform 28 and the drive motor Ⅲ 27 are transmitted through the transmission component Ⅲ 29. A lifting component 32 is installed on the rotating platform 28. The lifting component 32 is a cylinder. A rotating plate 30 is fixed to the telescopic rod of the cylinder. Electric clamps 31 are installed on the front and rear sides of the bottom of the rotating plate 30. A receiving plate 33 is installed on the front side of the support platform 3 by bolt connection. A storage plate 34 is installed in the middle of the top of the support platform 3.

[0031] See Figures 2-4 As shown, the fiber optic connector placement assembly includes a limiting plate 4, a placement frame 5, a placement tray 6, a height limiting plate 7, and a lifting machine 8. Two limiting plates 4 are installed on the top of the support platform 3 by bolt connection. Two lifting machines 8 are installed on each side of the two limiting plates 4 that are close to each other. The placement frame 5 is installed between the two lifting machines 8. The placement tray 6 is installed at the bottom of the placement frame 5. Multiple material feeding slots are opened on the placement tray 6. The placement tray 6 is located above the sandpaper fixing tray 21. Two height limiting plates 7 are installed on each side of the two limiting plates 4 that are close to each other. The height limiting plates 7 are located above the placement frame 5.

[0032] See Figure 5 and Figure 6As shown, the sliding assembly includes a support plate I13, a drive motor I14, a threaded rod 12, a threaded ring 15, and a transmission assembly I16. The support plate I13 is fixedly connected to the lower part of the two guide blocks 9 by welding. The drive motor I14 is mounted on the support plate I13. The threaded rod 12 is rotatably mounted on the lifting seat 11 and passes through the support plate I13. The threaded ring 15 is rotatably mounted on the support plate and is threadedly connected to the threaded rod 12. The threaded ring 15 is connected to the output shaft of the drive motor I14 by the transmission assembly I16. The transmission assembly I consists of two pulleys and a flat belt. The output shaft of the drive motor I14 and the threaded ring 15 are both equipped with pulleys, and a flat belt is sleeved between the two pulleys.

[0033] See Figures 5-7 As shown, the drive assembly includes a support plate II17, a drive motor II18, and a transmission assembly II20. The support plate II17 is fixedly connected to the two connecting rails 10 by welding. The drive motor II18 is installed on the support plate II17 by bolt connection. The output shaft of the drive motor II18 passes through the support plate II17. The mounting plate 19 and the output shaft of the drive motor II18 are connected by the transmission assembly II20.

[0034] When polishing the fiber optic connector, first place the fiber optic connector in the placement tray 6 and fix it. Then start the drive motor II 18. The drive motor II 18 drives the mounting tray 19 to rotate through the transmission assembly II 20. The mounting tray 19 further drives the sandpaper fixing tray 21 to rotate. Next, start the drive motor I 14. The drive motor I 14 drives the threaded ring 15 to rotate clockwise through the transmission assembly I 16. The threaded ring 15 then drives the threaded rod 12 to rotate clockwise. The threaded rod 12 drives the connecting rail 10, the support plate II 17 and the sandpaper fixing tray 21 to move upward through the lifting seat 11 until the sandpaper fixing tray 21 is in contact with the fiber optic connector. The bottom of the connector contacts the sandpaper, allowing the sandpaper holder 21 to grind the fiber optic connector. When the sandpaper holder 21 moves upward and contacts the fiber optic connector, the height limit plate 7 restricts the height of the placement rack 5 to prevent the sandpaper holder 21 from pushing the placement tray 6 out of the working area. When the sandpaper needs to be replaced, the new sandpaper holder 21 is first placed on the receiving tray 33. Then, the output shaft of the drive motor I 14 is reversed, causing the threaded ring 15 to drive the threaded rod 12 to reverse. The threaded rod 12 drives the connecting rail 10, support plate II 17, and sandpaper holder 21 to move downward through the lifting seat 11. Then, the drive motor II 18 is turned off. The drive motor Ⅲ27 is started, and the drive motor Ⅲ27 drives the rotary table 28 to rotate through the transmission assembly Ⅲ29. The rotary table 28 drives the rotating plate 30 to rotate, so that one of the electric clamps 31 is positioned above the receiving tray 33 and the other electric clamp 31 is positioned above the placing tray 34. Then, the lifting assembly 32 is controlled to move the receiving tray 33 and the sandpaper fixing tray 21 downward. Then, the two electric clamps 31 are controlled to clamp the sandpaper fixing tray 21 on the receiving tray 33 and the placing tray 34 respectively. Then, the lifting assembly 32 is controlled to move the receiving tray 33 and the sandpaper fixing tray 21 upward. Finally, the drive motor Ⅲ27 is controlled to rotate. The output shaft of 7 reverses, and the rotary table 28 drives the rotating plate 30 to reverse, so that the positions of the two electric clamps 31 are interchanged. Then, the two electric clamps 31 are controlled to release the sandpaper fixing plate 21. The used sandpaper fixing plate 21 falls onto the receiving plate 33, and the new sandpaper fixing plate 21 is placed on the mounting plate 19, thereby realizing the automatic replacement of the sandpaper fixing plate 21. After the sandpaper replacement is completed, the drive motor II 18 is restarted so that the new sandpaper fixing plate 21 grinds the fiber optic connector. This improves the flexibility of sandpaper fixing plate 21 replacement, reduces downtime caused by sandpaper replacement, and improves work efficiency.

[0035] Example 2: Based on Example 1, refer to Figures 8-9 As shown, it also includes a fixed shell 22, a sliding rod 23, a locking block 24 and a pressure rod 25. Multiple fixed shells 22 are fixedly connected to the placement plate 6. The sliding rod 23 is slidably arranged inside the fixed shell 22. The sliding rod 23 is inclined inside the fixed shell 22. The locking block 24 is installed at the lower end of the sliding rod 23. The pressure rod 25 is rotatably arranged at the upper end of the sliding rod 23.

[0036] When the fiber optic connector needs to be placed on the placement tray 6, first rotate the pressure rod 25 downwards. The pressure rod 25 drives the sliding rod 23 to slide upwards, and the sliding rod 23 drives the locking block 24 to slide upwards. Then place the fiber optic connector in the feeding slot of the placement tray 6, and then rotate the pressure rod 25 upwards. The pressure rod 25 drives the sliding rod 23 to slide downwards, and the sliding rod 23 drives the locking block 24 to slide downwards to abut against the fiber optic connector, thereby fixing the fiber optic connector.

[0037] See Figures 10-12 As shown, it also includes an electric slide rail assembly 35, an electric slide rail assembly 36, a connecting plate 41, an electric disk 37, an electric push rod 38, and a cleaning roller 39. The electric slide rail assembly 35 is installed on the limiting plate 4 located on the front side. The electric slide rail assembly 36 is installed on the electric slide rail assembly 35 by bolt connection. The connecting plate 41 is installed on the lower part of the electric slide rail assembly 36 by bolt connection. The electric disk 37 is installed on the lower part of the connecting plate 41 by bolt connection. The electric push rod 38 is installed on the lower part of the electric slide rail assembly 36. The cleaning roller 39 is installed on the telescopic rod of the electric push rod 38.

[0038] After the sandpaper holder 21 is replaced, the electric slide rail assembly 35 is activated. This assembly drives the electric slide rail assembly 36, connecting plate 41, electric disk 37, electric push rod 38, and cleaning roller 39 to move to the left until the electric disk 37 is above the replaced sandpaper holder 21. Then, the electric slide rail assembly 36 is controlled to move the connecting plate 41 and electric disk 37 downwards, so that the electric disk 37 approaches the sandpaper holder 21. Next, the electric disk 37 is controlled to hold the sandpaper holder 21. Then, the electric slide rail assembly 35 is controlled to move the entire mechanism to the right to reset. Then, the electric slide rail assembly 36 and electric disk 37 are controlled to make the replaced sandpaper holder 21 fall onto the storage tray 34. After completing the above steps, the electric push rod 38 is activated. The extension and retraction of the electric push rod 38 causes the cleaning roller 39 to move back and forth, cleaning the debris on the sandpaper holder 21, making it easy to reuse the sandpaper holder 21.

[0039] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present invention. Those skilled in the art will understand that variations of the present invention will be included within the scope of the claims herein.
