An optical fiber preform deposition preparation device and deposition method thereof

Abstract

The invention discloses an optical fiber preform deposition preparation device and a deposition method thereof, and relates to the technical field of optical fiber preform manufacture. Silicon oxide particles are attached to the mandrel; the driving device, the driving device includes a horizontal driving device and an angle driving device, both of which are connected to the blowtorch bracket, and the horizontal driving device drives the blowtorch bracket to reciprocate horizontally, and the angle driving device adjusts The position of the blowtorch on the working area on the mandrel; several distance sensors, several distance sensors are located on the same straight line on the same horizontal plane, and the straight line is parallel to the mandrel axis, and the distance sensors are used to detect the deposition thickness on the mandrel surface; the controller, The controller is respectively connected with the horizontal driving device, the angle driving device and the distance sensor. The invention can carry out stable deposition and avoid product damage or defective products.

Description

technical field [0001] The invention relates to the technical field of optical fiber preform manufacturing equipment, in particular to an optical fiber preform deposition preparation device and a deposition method thereof. Background technique [0002] On the optical fiber preform manufacturing equipment, a blowtorch is used to deposit the surface of the mandrel in real time. Generally, the spraying angle between the blowtorch and the surface of the mandrel is fixed. However, the deposition on the surface of the mandrel is easily affected by the surrounding environment, and it cannot be guaranteed that each deposition will go smoothly. There will be uneven deposition on the surface of the mandrel, which will cause defective products and unstable deposition. During the next sintering process of the preform, product damage or poor product characteristics may occur. Contents of the invention [0003] In view of the defects existing in the prior art, the object of the present...
