Embodiment 1
[0027] The optical fiber to be polished is placed on the glass-ceramic for placing the V-shaped grooved fiber, and the positioning reference block glass-ceramic is located at the horizontal position behind the glass-ceramic for placing the V-shaped grooved fiber, which is used to calibrate its relative height. The control motor provides the control voltage of the PZT to adjust the upper and lower positions of the V-groove optical fiber placement glass ceramics. The glass ceramics for grinding and polishing are placed on the grinding block support frame directly above the glass ceramics for placing V-shaped grooved optical fibers. The grinding block support frame is connected to the conveyor belt, and the speed of the conveyor belt is adjusted by controlling the motor to drive the grinding block. Pan in 1D at different speeds. The back-and-forth movement distance of the grinding block is determined by the positioning sensor. The electrode is placed on the slide rail just above ...

[0041] Embodiment 3: The present invention can achieve grinding accuracy as high as 0.01 μm, grinding length greater than 100 mm, and simultaneous grinding of multiple optical fibers. Select multiple optical fibers to be polished with the same parameters and soak them in acetone solution for about ten minutes, then use wire strippers to remove the coating layer of optical fibers to be polished; use glass ceramics for grinding and polishing with a width greater than the total cross-sectional width of multiple optical fibers to be polished Put it on the grinding frame, then place multiple optical fibers to be polished on the glass-ceramics for placing V-shaped grooved optical fibers, and put the head and tail ends of the optical fibers to be polished into multiple parallel grooves corresponding to both ends, so that Multiple optical fibers to be polished are strictly parallel, hang them with clips to avoid movement of the optical fibers to be polished, and finally use two small m...
