Method and device for stripping loose bodies of optical fiber preform rod

Abstract

The invention discloses a method and device for stripping loose bodies of an optical fiber preform rod. The method comprises the following steps: (1) cooling the loose bodies of the optical fiber preform rod; (2) putting the loose bodies of the optical fiber preform rod into a placement platform; (3) controlling a stripping air cylinder to move repeatedly, and carrying out stripping treatment once on the loose bodies at the outer side of a core rod; (4) repeating the step (3); (5) repeating the step (4) until the minimum distance between the loose bodies and the core rod is in a specific range; (6) carrying out instant cooling on the loose bodies at the outer side of the core rod so as to burst out the loose bodies; and (7) carrying out acid-etching on the core rod. According to the method and the device, cutting knifes are driven by the stripping air cylinder, so that the loose bodies can be stripped automatically and rapidly; the cutting knifes are driven by the stripping air cylinder, so that the cutting knifes can be adjusted through controlling the pressure of the stripping air cylinder; and the loose bodies of the optical fiber preform rod can be automatically cut, so that the labor intensity for laborers is lightened.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to a device and method for stripping loose optical fiber preformed rods. Background technique [0002] The OVD method is used to manufacture optical fiber preforms. The principle is to react gaseous halides with oxyhydrogen flames or methane flames to produce a large amount of silica "dust" particles, which are deposited layer by layer as the mandrel moves back and forth. After the outer surface of the core rod is deposited, it is sintered and vitrified to obtain an optical fiber preform. Its production diagram is as follows figure 1 As shown: the blowtorch 3 of the halogenation reaction can produce a large amount of silica "dust" particles, the mandrel 1 is fixed on the equipment, can rotate, and move left and right, and the loose body of dust 2 is deposited on the mandrel 1. [0003] In the event of abnormal conditions such as equipment abnormality and raw material abnorm...

AI Technical Summary

Problems solved by technology

Workers use an ax to strip the loose body of the preform rod. Due to the high density of the loose body of the optical fiber preform rod, it is time-consuming and laborious to peel off, resulting in high labor intensity and low stripping efficiency.
