Description
Art
The invention belongs to optical-fibre precise winding technology field, it is related to a kind of varied tention and adjusts and control device, especially may be used
Change varied tention when layer is wound around to adjust and control device for optical fiber.
Background technology
Optical fiber, with its unique material and fine quality, is used widely in national economy field, especially in military affairs side
Face.Optical-fibre guidance tool has broad application prospects, and optical-fibre precise winding is an important technology in optical-fibre guidance.Optical fiber
Precision-wound is exactly that with the winding pattern of certain winding tension and regulation, successively zero defect is critically wound into coiling by optical fiber
Guan Shang, ultimately forms a winding meeting winding precision requirement.During Optical Fiber Winding, winding tension is crossed conference and is caused to pass
The decay of defeated signal and loss, winding tension is too small to affect compression degree on winding for the optical fiber, and affects optical fiber winding
Control requirement extremely strict winding tension during stability, therefore Optical Fiber Winding.Dissimilar according to fibre diameter and product
And demand, domestic at present commonly used winding process be winding tension is controlled a certain stable in the range of 80～300 grams
Value, and tension force precision is ± 5 grams.
In optical-fibre precise winding technology field, currently known technology is to adopt constant tension control device, in optical-fibre precise
In winding process, certain pressure is applied to optical fiber from the counterweight of dancing wheel or fixed mass, make optical fiber with invariable tension force
Successively it is wound.Because optical fiber winding is made up of plurality of layers, under identical tension winding, the outer layer optical fiber being wound around afterwards can be right
The inner layer optical fiber having wound produces obvious radial compression and acts on so that the stress difference of ectonexine optical fiber is very big；With

There is larger difference in winding ectonexine stress and strain, more can cause again dividing of inside and outside ply stress when temperature changes
Cloth, easily causes deformation and the cracking of optical fiber winding, greatly have impact on the stability of optical fiber winding, it is desirable to when being wound around
Using the varied tention canoe from large to small of tension force from inside to outside, to avoid or to eliminate in optical fiber winding number of plies increase causes
Outer layer stress and strain difference, improves signal transmission performance and the stability of optical fiber winding further.
The canoe of existing fiber winding process still commonly used traditional constant tensile control.Although control method is simple
And be easily achieved, but because its structure and algorithm are excessively simply it is impossible to realize the canoe of variable tension control；With regard to can be used for
The varied tention that optical-fibre precise is wound around is adjusted and control device, has no and refer in the document published and report.
