Description

Technical Field

[0001] This utility model relates to the field of optical fiber polishing technology, specifically to an optical fiber polishing device. Background Technology

[0002] The fiber coupling process places high demands on the end faces of the two coupling fibers. Generally, during the fabrication of fiber optic connectors, the connectors need to be polished to reduce coupling loss and improve optical transmission efficiency.

[0003] Publication number CN215748401U discloses a fiber optic connector end-face polishing device. This patent uses a clamping mechanism on the surface of an L-shaped plate to facilitate the use of spring elasticity to press the clamping plate, which in turn works with the slot plate to clamp and limit the fiber optic connector end, while providing good elastic buffer protection to prevent damage caused by excessive clamping force. Furthermore, the adsorption mechanism allows for easy manual adjustment of the placement of the dust suction head by moving the metal shaping hose, which adsorbs and collects dust from the surface of the polishing disc. The adsorbed dust is stored in a dust collection box, purifying the working environment and protecting the health of the workers. However, this patent still has the following problems in actual use: In the process of optical fiber end grinding, different grinding discs with different coarseness are required to adapt to the processing needs of different stages. When coarse grinding is used to quickly remove excess material, a coarser grinding disc is required. After the workpiece has been coarsely ground, it has basically reached the required shape and approximate size. Next, more refined processing is required to improve surface quality and dimensional accuracy. At this time, a grinding disc with finer particles and relatively lower hardness is required. Then, to achieve extremely high gloss and extremely low roughness on the workpiece surface, special polishing discs or grinding discs made of soft materials are used to polish the optical fiber. When grinding optical fibers, it is not convenient to change different grinding discs according to different processing stages, and it is not convenient to continuously grind the optical fiber.

[0004] An optical fiber polishing device is proposed to address the problems mentioned above. Utility Model Content

The positioning sleeve clamps and fixes the optical fiber between the mounting block and the positioning sleeve. Multiple optical fibers can be fixed at the same time, which is convenient for subsequent polishing of the optical fibers. Attached Figure Description

Four rotating rods 208 are rotatably connected equidistantly on the inside of the turntable 205, and a grinding disc 209 is fixedly installed on the top of each of the four rotating rods 208. Furthermore, a connecting groove 210 is provided at the top of the rotating shaft 202, and three slots 211 are equally spaced circumferentially inside the connecting groove 210. Four connecting strips 2081 are equally spaced circumferentially installed on the outer sides of the four rotating rods 208, facilitating the connection between the rotating rods 208 and the rotating shaft 202. A screw 212 is threadedly connected to the upper part of the fixed rod 204, and a positioning ring 213 is rotatably connected to the bottom of the screw 212. The positioning ring 213 is slidably connected to the fixed rod 204, and a guide rod 214 is fixedly installed on one side of the top of the positioning ring 213.

[0019] Working principle: Before using this fiber optic polishing device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 4As shown, when polishing the optical fiber, the optical fiber is fixed on the fixing cylinder 105. The electric push rod 102 is activated, causing the fixing cylinder 105 to move downwards, so that the optical fiber end abuts against the polishing disc 209. The servo motor 201 is activated, driving the rotating shaft 202 to rotate. Through the cooperation of the connecting strip 2081 and the slot 211, the rotating rod 208 rotates, causing the polishing disc 209 to rotate and polish the optical fiber end. When changing the polishing disc 209, the rotating screw 212 drives the positioning ring 213 to move upwards. The positioning ring 213 moves and no longer abuts against the turntable 205, allowing the turntable 205 to be pulled, causing the positioning block 206 to disengage from the positioning hole 207, and the rotating rod 208 to leave the connecting groove 210. This process is repeated for different optical fiber ends. The grinding disc 209 rotates to a position above the rotating shaft 202. Then, the turntable 205 is lowered, allowing the positioning block 206 to be inserted into the positioning hole 207, and the connecting strip 2081 to be inserted into the slot 211. The slot 211 is flared at the top for easy insertion. Then, the screw 212 is rotated in the opposite direction, causing the positioning ring 213 to abut against the turntable 205 to position the turntable 205. This allows the turntable 205 to rotate and switch between grinding discs 209 with different roughness levels. This enables the grinding discs 209 with different roughness levels to be changed at different stages when grinding the fiber end, facilitating continuous grinding of the fiber, improving the efficiency of fiber grinding, and enhancing practicality. When polishing optical fibers, the optical fiber is inserted into the through hole on the fixed cylinder 105. Then, the threaded rod 308 can be rotated to move the movable plate 306 downward. After the movable plate 306 moves downward, it can push the connecting rod 307 to rotate. After the connecting rod 307 rotates, it can push the movable rod 303 to slide on the fixed sleeve 302, so that the positioning sleeve 304 moves. The positioning sleeve 304 clamps and fixes the optical fiber between the mounting block 301 and the positioning sleeve 304. Multiple optical fibers can be fixed at the same time, which is convenient for subsequent polishing of the optical fibers.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
