Abstract

The invention discloses a wire drawing pretreatment device and method of an optical fiber preform. The device comprises at least one blowtorch, wherein the blowtorch comprises a first oxygen pipeline of which a first end is communicated with a first oxygen supply component, a second oxygen pipeline of which a first end is communicated with a second oxygen supply component, and a hydrogen pipeline of which a first end is communicated with a hydrogen supply component; and a second end of the first oxygen pipeline, a second end of the second oxygen pipeline and a second end of the hydrogen pipeline are respectively positioned on the sprayer of the blowtorch. The device and method disclosed by the invention can complete the whole wire drawing pretreatment process on the premise of performing one clamping process on the optical fiber preform, thereby lowering the wire drawing pretreatment complexity and enhancing the work efficiency.

Description

technical field [0001] The invention relates to the technical field of communication equipment manufacturing, in particular to a drawing pretreatment device and method for an optical fiber preform. Background technique [0002] With the advancement of technology, the size of optical fiber preforms is getting larger and larger, among which, optical fiber preforms with a diameter of more than 120 mm and a weight of more than 60 kg are called large-size optical fiber preforms. The tapered part of this large-sized optical fiber preform has the risk of cracking due to manufacturing defects, so it cannot be directly drawn into an optical fiber. In order to improve the wire drawing strength, the surface needs to be polished in advance. The slitting process and polishing process here are collectively referred to as the wire drawing pretreatment process. [0003] like figure 1 as shown, figure 1 It is a schematic diagram of an optical fiber preform in the prior art, including a ta...
