Description
Technical field
The present invention relates to connection with fibre coating technical fields, and in particular to a kind of optical fiber room temperature set molding process.
Background technique
In order to ensure the optical property of optical fiber, need to carry out plastic sleeve protection in optical fiber surface, while optical fiber can also be improved
Mechanical performance, flame retardant property, pressure-resistant performance and ageing-resistant performance etc., perfect plastic sleeve technique could obtain the optical fiber of different characteristics
Laser propagation effect, existing optical fiber for lighting room temperature plastic sleeve mainly includes following technique: it is cooling that optical fiber puts fine frame → extruding machine → hot water
Slot → wheeled remaining long traction → main traction → the caliper of cold water cooling bath → hair dryer → crawler type → traction control frame → receipts row
The processes such as line apparatus processing, to reach the protection of optical fiber.This process requirement is in advance by sheath skin heating and melting, in plastics and light
Fibre contact when temperature it is higher, generally about 200 DEG C or so, in this way caused by optical fiber damage it is larger, it is not only time-consuming and at
This is also relatively high, and due to whole process, temperature change is larger, has a great impact to the material of optical fiber, thus to light
Fine consistency has a great impact.So there is temperature is excessively high and temperature becomes in prior art connection with fibre coating method
Change the influence after causing connection with fibre coating greatly to optical fiber quality.
Summary of the invention
In order to solve, temperature present in prior art connection with fibre coating method is excessively high and temperature change causes greatly optical fiber
To the influence of optical fiber quality after plastic sleeve, the present invention provides a kind of optical fiber room temperature set molding process.
The present invention is achieved by the following technical solution:
A kind of optical fiber room temperature covers molding process, the optical fiber in plastic sleeve the following steps are included:
S1: optical fiber unwrapping wire；
S2: sheath skin unwrapping wire；The sheath skin is strip, and width matches with by the diameter of package optical fiber；
S3: during optical fiber and sheath skin unwrapping wire simultaneously, sheath suitcase wraps up in optical fiber and wraps up in interface to sheath suitcase
Apply bonded adhesives；
S4: bonding adhesive curing；
S5: the outer diameter sheath after measurement bonding adhesive curing, discovery failure are adjusted preceding step；
S6: take-up is carried out to the optical fiber for being cased with sheath.
Further, the optical fiber unwrapping wire uses constant-tension unwrapping wire, and constant-tension is 10N ~ 30N.
Further, the sheath skin unwrapping wire uses constant-tension unwrapping wire, and constant-tension is 10N ~ 20N.
Further, the sheath skin is the transparent or semitransparent sheath skin of PVC base, and it is opaque that inner surface is sprayed with black
Paint.
Further, the bonded adhesives is shadowless glue, and is solidified by the way of ultraviolet light irradiation.
Further, tractor is provided in the take-up, and hauling speed is 60 ~ 100m/min.
The beneficial effect comprise that: it is wrapped up in after optical fiber by sheath suitcase to carrying out applying bonding glue sticking at package,
Then to bonding adhesive curing, plastic layer is formed around optical fiber with this, optical fiber is protected, The method avoids existing
The process to sheath skin heating and melting is needed in technology, also avoids the process of subsequent cooling, whole process is under normal temperature state
It carries out, solves that temperature is excessively high and temperature change causes greatly influence after connection with fibre coating to optical fiber quality.
Detailed description of the invention
Fig. 1 is a kind of optical fiber room temperature plastic sleeve method schematic diagram of the present invention.
In figure: (1) optical fiber wire releasing device, (101) optical fiber, (2) sheath actinobacillus device, (201) sheath skin, (3) sheath skin
Wrap up in optical fiber and glue stations, (4) ultraviolet lamp, (5) measuring device, the optical fiber cable of (6) with sheath, (7) take-up,
(8) tractor.
Specific embodiment
It will describe in detail in conjunction with specific embodiments with reference to the accompanying drawings below:
Plastic sleeve is carried out to optical fiber and uses following methods:
S1: optical fiber unwrapping wire；
S2: sheath skin unwrapping wire；The sheath skin is strip, and width matches with by the diameter of package optical fiber；
S3: during optical fiber and sheath skin unwrapping wire simultaneously, sheath suitcase wraps up in optical fiber and wraps up in interface to sheath suitcase
Apply bonded adhesives；
S4: bonding adhesive curing；
S5: the outer diameter sheath after measurement bonding adhesive curing, discovery failure are adjusted preceding step；
S6: take-up is carried out to the optical fiber for being cased with sheath.
The present invention carries out active unwrapping wire to optical fiber (101) in practice, using optical fiber wire releasing device (1), uses sheath
Skin actinobacillus device (2) carries out active unwrapping wire to sheath skin (201)；It wraps up in optical fiber and glue stations (3) in sheath skin, cuts off first
Extra sheath skin (201) after package optical fiber, then wraps up in interface to sheath suitcase and applies bonded adhesives；It is painted with after bonded adhesives to bonding
Glue is solidified；Then by the outer diameter sheath after measuring device (5) measurement bonding adhesive curing, discovery failure walks front
Suddenly it is adjusted, the resection of sheath skin or the tension etc. of sheath skin unwrapping wire after adjustable package optical fiber；Finally to qualification
Be cased with sheath optical fiber (6) carry out take-up.
