A large size sleeve optical rod assembly equipment

Abstract

The invention relates to large size sleeve pipe optical rod assembling equipment, and belongs to the technical field of optical rod and optical fiber processing. The equipment is composed of a core rod storage device, a core rod assembling device, and a sleeve pipe assembling device. The front termination of the core rod assembling device is provided with the core rod storage device through a connection piece A. The rear termination of the core rod assembling device is provided with the sleeve pipe assembling device through a connection piece B. The equipment can precisely place a preform core rod in a predetermined position in a sleeve pipe, which has been subjected to tapering, without any wear through an adjusting roller, an elevating mechanism, and a roller finely adjusting device, and completes the manufacturing of large size optical fiber preform. The large size sleeve pipe optical rod assembling equipment has low requirements on the height of used space; due to the functional module assembly structure, the equipment is easy to disassemble and transport, the core rods can be stored and dried intensively, the consumption amount of clean gas is low, the operation height is reduced, and the risk that core rods fall down and break is reduced.

Description

technical field [0001] The invention relates to a large-size casing optical rod assembly equipment, which belongs to the technical field of optical rod and optical fiber processing. Background technique [0002] Drawing with a large-size optical fiber preform can effectively improve the utilization rate of raw materials and production efficiency, which makes the large-size preform have a cost advantage, and it can also improve the quality of the optical fiber in the following two aspects: 1. The dilution effect of the large-size preform The attenuation of the optical fiber is further reduced. 2. After the large-size sleeve is machined, its roundness and concentricity are better, which can ensure the geometric performance of the optical fiber; large-size optical fiber preform has become the mainstream trend in the current market. [0003] However, the existing large-size preform and casing assembly equipment is generally installed vertically, which not only requires complex p...

Problems solved by technology

[0003] However, the existing large-size preform and casing assembly equipment is generally installed vertically. Not only is the processing equipment complicated, but also the space height for equipment operation is high. At least the space height needs to be 7-8m high, and it is difficult for general workshops to meet this height. Requirements, the erection and assembly of the whole set of equipment are also quite difficult
