Embodiment

[0037] This embodiment provides an OVD deposition device with a high deposition pass rate, such as figure 1 and figure 2 shown, including:

[0038] The deposition box 1 has a deposition cavity 11 for accommodating the preform soot or core rod 3;

[0039] The support structure 2 is arranged on one side of the deposition cavity 11; as image 3As shown, the bearing support structure 2 includes a fixed seat 21 (specifically, a bearing seat), a sliding ring 22 (specifically, a bearing), a fixed tube 23, and a pressing member 24. The fixed seat 21 is arranged in the deposition box 1 , the sliding ring 22 is accommodated in the fixing seat 21, the fixing tube 23 extends into the hole of the sliding ring 22 from one side of the sliding ring 22, and the cavity of the fixing tube 23 is provided with a loose body or a core for fixing the preform rod The elastic part 25 of the rod 3 (such as the O-shaped rubber sealing ring for the loose body of the preform rod or the mandrel 3 to pas...

Abstract

This application relates to an OVD deposition device with a high deposition pass rate, including: a deposition box, a support structure, a chuck rod fixing structure, a blowtorch, and an exhaust system; wherein, the support structure is arranged on one side of the deposition inner cavity, including a fixing seat , a sliding ring, a fixing tube, and a pressing piece are used to fix one end of the prefabricated rod loose body or mandrel. The chuck rod at the other end is connected with the driving device and can be driven by the driving device to rotate. The OVD deposition device of the present application prevents the preform loose body or mandrel from sliding in the sliding bearing support structure or slipping out of the bearing support structure, thereby ensuring that the entire preform soot body or mandrel does not move back and forth or slip out of the fixture , which improves the deposition qualification rate of the preformed loose body or mandrel.

Description

technical field [0001] The application belongs to the technical field of optical fiber preform manufacture, and in particular relates to an OVD deposition device with high deposition pass rate. Background technique [0002] The OVD process (that is, external vapor deposition method) is one of the main process methods for preparing low water peak or zero water peak single-mode optical fiber preforms. This process can produce larger-sized optical fiber preforms, which can effectively reduce manufacturing costs. It is widely used by mainstream optical fiber preform manufacturers at home and abroad. The OVD process has unique technical advantages as a process for producing preforms. Its main principle is to spray high-purity gas-phase raw materials (usually silicon tetrachloride evaporation raw materials) on the outside of the mandrel through a blowtorch. 2 Chemical reaction with water vapor to form SiO 2 Fine particles are deposited on the mandrel by the thermophoretic effect...
