An ovd deposition and sintering combination device

Abstract

The invention relates to the technical field of vapor deposition, in particular to an OVD deposition and sintering combination device. The OVD deposition and sintering combination device includes: a rotary transport mechanism, a deposition chamber and a sintering furnace. The rotary movement mechanism includes at least three vertical lifting arms, all vertical lifting arms are evenly spaced on the same circumference, and can rotate along the circumference at the same speed at the same time, and the lower ends of all vertical lifting arms are equipped with a rotating grabbing structure The deposition chamber is arranged on the circumference, including two vertically arranged and openable deposition chamber walls, so that the vertical lifting arm can rotate and move on the circumference with the mandrel captured by the rotating grabbing structure; the sintering furnace is located at On the circumference, the distance between the deposition chamber and the deposition chamber is equal to the distance between the two vertical lifting arms. The vertical lifting arms can be raised and lowered to place the mandrel in the sintering furnace or take it out of the sintering furnace. It can solve the problems of low efficiency and easy damage to loose bodies in the prior art that multiple transfer links are required between the VD process and the sintering process.

Description

technical field [0001] The invention relates to the technical field of vapor deposition, in particular to an OVD deposition and sintering combination device. Background technique [0002] OVD (Outside Vapor Deposition, external vapor deposition) can prepare larger-sized optical fiber preforms than in-tube deposition, so it has more development potential. [0003] In the manufacturing process of optical fiber preform, the OVD process is to deposit raw materials on the outside of the mandrel to produce a loose body; after the deposition of the loose body is completed, the product enters the sintering process equipment through various transportation devices; sintered in the sintering furnace to form Transparent finished products; OVD process and sintering process, as well as various transportation devices in between, are all important links in the manufacturing process of optical fiber preforms. [0004] In the prior art, multiple transfer links are required between the OVD pr...
