Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical fiber end face processing technology, and more specifically, to a novel optical fiber end face polishing device. Background Technology
[0002] Optical fiber is a light transmission tool that utilizes the principle of total internal reflection of light in fibers made of glass or plastic. It plays an important role in the field of modern communication. In order to ensure the efficiency and stability of data transmission, the end face of the optical fiber needs to undergo fine polishing to achieve optimal performance. Therefore, the optical fiber polishing process is extremely important in the optical fiber manufacturing process, as it directly determines the transmission quality of light waves in the optical fiber.
[0003] Currently, the main method for polishing fiber end faces involves inserting the fiber core, with its coating and protective layer stripped, into a specific fixture such as a ceramic ferrule or glass block, and then polishing the end face of the fiber core. However, this polishing technology has the following drawbacks:
[0004] First, the complex structure of the fiber polishing and loading fixture increases the difficulty of operation. Furthermore, the fiber core is very fragile without a coating or protective layer. The complicated operation process makes it easy for operators to make mistakes when loading the fiber. For example, if a certain component is not installed correctly, the fiber will not be fixed accurately and will have to be reloaded. At the same time, due to the fragility of the fiber core, even a slight external force during loading can cause the fiber to break. Operators will have to take the fiber and reload it, which undoubtedly wastes a lot of time and energy and seriously reduces the efficiency of operation.
[0005] Second: In an optical coupler, the ideal fiber end face shape is inclined or curved to better couple light from one fiber to another. However, during the polishing process, the fiber clamp cannot rotate, resulting in a uniform fiber end face shape, which fails to improve the propagation quality of light waves in the fiber.

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0057] Example 1
[0058] like Figures 1-2As shown, this utility model provides a novel optical fiber end-face polishing device, including a worktable 1 and a polishing machine 11 mounted on the worktable 1. The polishing machine 11 includes a time setting panel, a display panel, a polishing turntable rotation switch, and an optical fiber clamp rotation switch. The time setting panel is used to specify the working time of the polishing machine 11 and the clamping cylinder 14. The operator can set the working time of the polishing machine 11 and the time for the clamping cylinder 14 to rotate the optical fiber according to the specific needs of optical fiber polishing, which helps to improve polishing quality and production efficiency. The polishing turntable rotation switch controls the operation of the polishing machine 11. Through this switch, the operator can flexibly start or stop the polishing operation and adjust the polishing process at any time according to the actual situation. The optical fiber clamp rotation switch controls the clamping cylinder 14 to rotate the optical fiber. When the switch is turned on, the optical fiber clamp drives the optical fiber to rotate around its own axis, so that the optical fiber end face can be evenly stressed during the polishing process, which helps to form various complex end-face shapes. To improve the propagation quality of light waves in optical fibers, an adjusting rod 12 is located on one side of the polishing machine 11. The top of the adjusting rod 12 has a vertically movable fiber optic bracket 13. A clamping cylinder 14 is located at the end of the fiber optic bracket 13 away from the adjusting rod 12 for threading the optical fiber. A fiber height adjusting knob 15 on the adjusting rod 12 is used to lock the fiber optic bracket 13, fixing the fiber's vertical position. This vertical movement allows for precise adjustment of the contact distance between the optical fiber and the polishing turntable, ensuring the fiber contacts the polishing turntable with appropriate pressure during polishing, thus guaranteeing the uniformity and accuracy of the polishing process. An electronic detector 16 is located on the side of the polishing machine 11 opposite to the adjusting rod 12, used to observe and measure the angle of contact between the optical fiber and the polishing turntable. Real-time angle feedback from the electronic detector 16 allows operators to adjust the position and angle of the optical fiber in a timely manner, ensuring the polishing process is always performed in optimal condition, further improving polishing accuracy and product quality.
[0059] like Figures 2-4As shown, the quick-locking device 2 is located inside the clamping cylinder 14 and is used for quickly locking the optical fiber. The quick-locking device 2 includes: a locking seat 21 installed in the middle of the clamping cylinder 14, which has a square shape and a hollow middle section; a movable hole 22 located inside the locking seat 21; two linkage wheels 23 symmetrically rotatably connected to the movable hole 22; and two half-plates 24 symmetrically installed on the linkage wheels 23, with a passage between the two half-plates 24 for inserting... The optical fiber has a groove, and the half-lobe plate 24 has a semi-circular arc shape; the gear plate 25 is vertically slidably connected to the movable hole 22 and meshes with the linkage wheel 23; the linkage hole 26 is opened above the locking seat 21; the expansion spring plate 27 is installed inside the linkage hole 26, and the lower part of the expansion spring plate 27 is fixedly connected to the gear plate 25; the drive rod 28 is installed below the expansion spring plate 27, and one end of it slides through the lower part of the locking seat 21; the drive ring 29 is installed at the lower end of the drive rod 28.
[0060] When fiber optic cable installation is required, press the drive ring 29. The drive ring 29 drives the drive rod 28 upward, which in turn pushes the expansion spring plate 27, causing the connected gear plate 25 to move upward synchronously. The upward movement of the gear plate 25 drives the meshing linkage wheel 23 to rotate. The rotation of the linkage wheel 23 unfolds the two half-plates 24 mounted on it, forming a space for fiber optic cable insertion. After inserting the fiber optic cable and exposing 2-3 cm of the inner core outside the clamping cylinder 14, release the drive ring 29. Under the rebound force of the expansion spring plate 27, the components move in opposite directions, and the two half-plates 24 close. The optical fiber is tightly locked inside the clamp cylinder 14. The quick-locking device 2 can open and close the half-lobe plate 24 by simply pressing the drive ring 29, quickly completing the installation and locking of the optical fiber. This eliminates the need for complicated multi-step operations, greatly saving optical fiber installation time and improving work efficiency. Furthermore, during the optical fiber installation process, the opening and closing of the half-lobe plate 24 is relatively smooth, and the force applied to the optical fiber during the locking process is uniform, reducing the risk of damage to the fragile uncoated and protective fiber core, lowering the possibility of optical fiber breakage, and saving optical fiber material costs.
[0061] The conical structure in the middle between the two half-plates 24 can guide the optical fiber to automatically align with the center position when the optical fiber is inserted between the two half-plates 24, achieving precise positioning. In addition, a rubber pad is installed inside the groove. When the half-plates 24 close and clamp the optical fiber, the rubber pad will undergo elastic deformation, thereby buffering the pressure exerted by the half-plates 24 on the optical fiber.
[0062] Example 2
[0063] like Figure 2 , Figure 5 and Figure 6As shown, the self-rotation drive assembly 211 is located inside the fiber optic frame 13 and is used to rotate the clamping cylinder 14 above the grinding machine 11. The fiber optic frame 13 has a movable slot on one side of the clamping cylinder 14. The self-rotation drive assembly 211 includes two synchronous pulleys 212, which are rotatably connected in the movable slot. A motor for starting the rotation of one of the synchronous pulleys 212 is installed below the fiber optic frame 13. A synchronous belt 213 is driven to the outside of the two synchronous pulleys 212. A fixed base 215 is slidably connected to the adjusting rod 12. The fiber height adjustment knob 15 is threadedly connected to the fixed base 215. The fixed base 215 has a back... One end of the adjusting rod 12 has an arc-shaped structure, and the fixed base 215 is hollow. Angle bracket 216 is rotatably connected to the fixed base 215 and has an arc-shaped structure, and is fixedly connected to the fiber optic bracket 13. Worm 217 is rotatably connected to the lower part of the fixed base 215. The lower part of worm 217 rotates through the fixed base 215 and is equipped with a fiber optic angle adjustment knob. Worm wheel 218 is rotatably connected inside the fixed base 215 and meshes with worm 217. Connecting plate 219 is rotatably connected to the rear end of the fixed base 215 and is coaxially fixedly connected to worm wheel 218. The upper inclined end of connecting plate 219 is fixedly connected to angle bracket 216.
[0064] When the angle of the clamping cylinder 14 needs to be adjusted, the operator rotates the fiber optic angle adjustment knob. This knob is connected to the worm gear 217. Rotating the knob will drive the worm gear 217 to rotate. The rotation of the worm gear 217 will drive the worm wheel 218 to rotate inside the fixed seat 215. When the worm wheel 218 rotates, it will drive the connecting plate 219 to rotate. The angle bracket 216 is rotatably connected to the arc-shaped structure of the fixed seat 215 and fixed to the fiber optic frame 13. Therefore, the rotation of the connecting plate 219 will cause the angle bracket 216 to rotate at the arc-shaped structure of the fixed seat 215, ultimately changing the angle of the clamping cylinder 14 connected to the fiber optic frame 13. After the motor is started, it will... One of the synchronous pulleys 212 rotates within the movable groove. The two synchronous pulleys 212 are connected by a synchronous belt 213. Therefore, the rotation of one synchronous pulley 212 will drive the other synchronous pulley 212 to rotate via the synchronous belt 213. The rotation of the synchronous pulley 212 will simultaneously drive the clamping cylinder 14 to rotate. The angle of the clamping cylinder 14 is adjusted through the worm gear 217 and worm wheel 218 transmission mechanism. This transmission method has high precision and stability, and can accurately adjust the polishing angle of the optical fiber according to different polishing requirements. This helps to achieve diverse optical fiber end face shapes and improve the propagation quality of light waves in the optical fiber.
[0065] Example 3
[0066] like Figure 2 , Figure 3 and Figure 7As shown, the connecting assembly 214 is mounted on another synchronous pulley 212 for quick connection with the clamping cylinder 14. The connecting assembly 214 includes: a connecting plate 2141, which is mounted on top of the synchronous pulley 212 located below the clamping cylinder 14 and is hollow; an assembly plate 2142, which is mounted below the clamping cylinder 14 and sleeved inside the connecting plate 2141; a locking block 2143, at least one in number, arranged in a ring shape on the outside of the assembly plate 2142; an L-shaped hole 2144, which is formed on the inside of the connecting plate 2141; a locking rod 2145, at least one in number, which is mounted below the expansion spring plate 27; and a locking hole 2146, which is formed on the connecting plate 2141.
[0067] When it is necessary to connect the clamp cylinder 14 to the synchronous pulley 212, the operator aligns the assembly plate 2142 below the clamp cylinder 14 with the connecting plate 2141 on top of the synchronous pulley 212, and inserts the assembly plate 2142 into the connecting plate 2141. During the process of inserting the assembly plate 2142 into the connecting plate 2141, the locking blocks 2143 arranged in a ring on the outer side of the assembly plate 2142 will align with the horizontal end of the L-shaped hole opened on the inner side of the connecting plate 2141, and then smoothly enter the horizontal end of the L-shaped hole. When the locking block 2143 reaches the bottom wall of the horizontal end of the L-shaped hole, the operator rotates the clamp cylinder 14, so that the locking block 2143 moves along the horizontal end of the L-shaped hole to the vertical end, so that the locking block 2143... After entering the vertical end, 143 can restrict the relative movement of the assembly plate 2142 and the connecting plate 2141 in the vertical direction, thereby achieving the connection and fixation of the two. At the same time as the locking block 2143 enters the vertical end of the L-shaped hole, the locking rod 2145 installed below the expansion spring plate 27 will be aligned and inserted into the locking hole 2146 opened on the connecting plate 2141. The connecting component 214 achieves a quick connection between the clamping cylinder 14 and the synchronous wheel 212 through the cooperation of the L-shaped hole and the locking block 2143, as well as the cooperation of the locking rod 2145 and the locking hole 2146. Compared with the traditional complex connection method, this quick connection method greatly saves connection time and improves work efficiency.
[0068] The working principle is as follows: This is a new type of optical fiber end face polishing device. When installing optical fiber, press the drive ring 29. The drive ring 29 drives the drive rod 28 to move upward, pushing the expansion spring plate 27, so that the connected gear plate 25 rises synchronously. The gear plate 25 drives the linkage wheel 23 that meshes with it to rotate, thereby allowing the two large semi-arc shaped half-lobes 24 installed on the linkage wheel 23 to unfold, forming an optical fiber insertion space. After inserting the optical fiber and leaving 2-3 cm of the inner core outside the clamping cylinder 14, release the drive ring 29. The rebound force of the expansion spring plate 27 causes the components to move in the opposite direction. The half-lobes 24 close and lock the optical fiber. The conical structure in the middle guides the optical fiber to be accurately positioned, and the rubber pad in the groove buffers the clamping pressure.
[0069] When the angle of the clamping cylinder 14 needs to be adjusted, the fiber angle adjustment knob is turned to drive the worm gear 217 connected to it to rotate. The worm gear 217 drives the worm wheel 218 to rotate in the fixed seat 215. The rotation of the worm wheel 218 drives the coaxial connecting plate 219 to rotate, thereby causing the angle bracket 216 fixed to the fiber frame 13 to rotate at the arc structure of the fixed seat 215, changing the angle of the clamping cylinder 14. After the motor is started, it drives one synchronous wheel 212 to rotate in the movable groove. The synchronous belt 213 drives another synchronous wheel 212 to realize the rotation of the clamping cylinder 14, which meets the requirements of different grinding angles and improves the diversity of fiber end face shape and the quality of light wave propagation.
[0070] When connecting the clamping cylinder 14 and the synchronous pulley 212, align the assembly plate 2142 below the clamping cylinder 14 and insert it into the connecting plate 2141 on top of the synchronous pulley 212. During this process, the locking block 2143 on the outer side of the assembly plate 2142 aligns with the horizontal end of the L-shaped hole on the inner side of the connecting plate 2141 and enters. After the locking block 2143 reaches the bottom wall of the horizontal end, rotate the clamping cylinder 14 to move the locking block 2143 along the horizontal end of the L-shaped hole to the vertical end, restricting the vertical relative movement of the assembly plate 2142 and the connecting plate 2141. At the same time, the locking rod 2145 below the expansion spring plate 27 aligns with and inserts into the locking hole 2146 on the connecting plate 2141, quickly completing the connection between the two.
