A kind of automated fiber optic deuterium processing equipment
Technical field
The present invention relates to a kind of field fiber, more particularly to a kind of automated fiber optic deuterium processing equipment.
Background technology
Optical fiber will produce some free groups of unordered Si-O in pulling process, easily generates Si-OH with H, causes
Water peak at 1385nm increases.Therefore various all-wave fibers will pass through deuterium processing after pulling silk, when can withstand long
Between ambient containing hydrogen erosion.
The principle of deuterium processing is that deuterium and the free groups of Si-O is allowed to form Si-OD, and absorption peak is in 1850nm, in this way in optical fiber
Their entire life, hydrogen can not just replace the position of deuterium.The reaction of deuterium and the free groups of Si-0 is as follows
Si-O + D2 → Si-OD
According to the requirements of ITU-T G.652C/D, optical fiber is in the decaying system after hydrogen aging at 1383 ± 3nm of optical fiber
It counts less than the decaying at 1310nm, all-wave fiber could be referred to as.
Needed in optical fiber production process carry out deuterium processing, due to the content of deuterium in air be it is negligible,
So needing optical fiber to be placed in a closed container to be passed through deuterium, allows optical fiber to be in deuterium environment and reacted.
Currently, deuterium processing equipment is a closed container with opening, opening has a sealing that can be opened and closed
Door needs that manually optical fiber is sent into sealing container by cart, time-consuming and laborious, the degree of automation when carrying out deuterium processing
It is not high, low production efficiency.

Further, the front door is driven by a hoist engine.
Further, the workbench is driven by a motor.
Further, the sealing structure A is that surface on the table is arranged and is corresponded to positioned at both side plate and front door bottom end
Sealing strip A at position.
Further, the sealing structure B include be arranged on the medial surface of front door and with both side plate and head cover front position
The air bag of corresponding position and the sealing strip B coordinated with air bag on both side plate and cover forward end is set.
Further, the sealing structure C is to be convenient for the sealing strip in sealing contact with back plate along what workbench rear end was arranged
C。
Further, the front door and side plate lower end are all the small end with sealing strip A cooperations.
Further, there is the seal groove for sealing strip A installations on the workbench.
The advantage of the invention is that:
(1)The optical fiber handling process and control flow for changing traditional optical fiber deuterium processing equipment, will manually carry
Optical fiber to sealing processing chamber is changed into can carry pending optical fiber to workbench, Suo Yougong with automation equipments such as supporting machinery hands
All automatically complete;Traditional integral seal process chamber is changed, using scientific and reasonable encapsulating method, that is, is met automatic
Change the leakproofness for requiring in turn ensure sealing processing chamber.
(2)Workbench makes travel table, and automation equipment is carried on pending optical fiber to workbench, subsequent motor
Leading screw is driven to realize the movement of workbench, and then sealing processing chamber forms a sealing entirety.
(3)It is slided up and down in sliding rack by steel wire rope, pulley, hoist engine, is carried out using air bag and sealing strip at sealing
Sealing, cylinder-pressing realize the automation of front door folding and sealing compression action by controller.
