Abstract

The invention creatively provides OVD deposition equipment capable of automatically adjusting deposition speed to match target weight. The equipment comprises a fixing frame and a support frame whichare correspondingly arranged on a workbench of a deposition box body, wherein a chuck rod for fixing a core rod is arranged on the fixing frame, a gravity sensor for monitoring the weight of the corerod in real time is arranged on the support frame, a deposition device connected with the gravity sensor is mounted on the workbench, a controller in the deposition device is matched with the sprayingamount of each shaft according to the weight fed back by the gravity sensor in real time, the deposition device comprises a feeding unit for providing raw materials for a blowtorch through a discharging pipe, and a differential pressure sensor is installed on the discharging pipe. According to the equipment and the method provided by the invention, the comprehensive percent of pass of wire drawing of the preform can be effectively improved, and the efficiency and the deposition capacity of OVD deposition equipment are improved.

Description

technical field [0001] The invention belongs to the technical field of OVD deposition equipment, and in particular relates to an OVD deposition equipment and method for automatically adjusting deposition speed to match target weight. Background technique [0002] The OVD process is currently one of the most excellent process methods for preparing low water peak or zero water peak single-mode optical fiber preforms, namely external vapor deposition method. This process is widely used by mainstream optical fiber preform manufacturers at home and abroad. The core rod prepared by OVD process is composed of two parts: the core layer and the optical cladding layer. The OVD deposition equipment mainly consists of five parts: chemical vapor reaction and deposition chamber, gas torch platform, soot preform rotating mechanism, exhaust system, and silicon tetrachloride evaporation cabinet. Silicon tetrachloride evaporation cabinet mainly includes material tank, heating rod, liquid le...
