Optical fiber preform rod polishing solution circulating system

Abstract

The invention mainly relates to the field of optical fiber preform rod inner hole and external cylindrical surface polishing, in particular to an optical fiber preform rod polishing solution circulating system, which comprises an upper water tank, a lower water tank, a first guiding pipe, a second guiding pipe, a third guiding pipe, a bending pipe, a first solenoid valve, a second solenoid valve, a left support seat, a right support seat, a water pump and a stirrer. The optical fiber preform rod polishing solution circulating system provided by the invention is simple in structure, high in integration level, and convenient to operate and install, a polishing solution used by the circulating system can be repeatedly used, and an excircle and an inner hole of an optical fiber preform rod immersed in a polishing agent loop can be polished.

Description

technical field [0001] The invention mainly relates to the field of polishing the inner hole and the outer cylindrical surface of an optical fiber preform, in particular to an optical fiber preform polishing liquid circulation system. Background technique [0002] The core of optical fiber manufacturing is optical fiber preform manufacturing technology. At present, the common optical fiber processing methods mainly include deposition method (chemical vapor phase, vapor phase outside the tube, plasma vapor phase) and mechanical method. The current process is to first manufacture the preform mandrel, and then use different techniques to manufacture the outer cladding outside the mandrel. Compared with the deposition method, the mechanical method has less initial investment and is suitable for batch processing of special optical fibers. The main implementation process of the mechanical method is the preparation of the original optical fiber glass, the processing of the pref...

AI Technical Summary

Problems solved by technology

Restricted by the mechanical properties of the optical fiber preform (high brittleness, easy to scratch the surface, etc.), shape (inner and outer cylindrical surfaces), size (length: 150mm, diameter: 20mm, inner diameter: 3-8mm) and equipment investment, etc., making The choice of polishing method has great limitations
