Description
Technical field
The present invention relates to optical fiber winding technique field, and in particular, it is related to a kind of Pneumatic Tension controller and optical fiber
Gyro ring winding machine.
Background technology
Fibre optic gyroscope belongs to high-precision sensor, and it is widely used in space flight and aviation, mechanical system and military technology
On.Fibre optic gyroscope has given full play to the features such as its low cost, easy maintenance, is just progressively substituting other type gyroscopes, and
Paid much attention to by user particularly army.Fiber optic loop is the important component of fibre optic gyroscope, the ring residing for fiber optic loop
Border factor, the nonreciprocal phase noise as caused by temperature, stress directly affect the precision and performance of optical fibre gyro.
Optical fiber in fiber optic loop is in winding process, because the influence of external environment condition and winding method can cause a variety of differences
The generation of the stress of factor, such as extraneous stress, the compression of winding.Fiber optic loop be by special optical fiber coil winding machine coiling and
Into extraneous stress can be by keeping optical fiber winding process external environment to eliminate.Therefore, the tension force suffered by the optical fiber on ring
It is main to be derived from the difference of take-up wheel speed and unwrapping wire wheel speed in optical fiber loop winding process.Therefore, to optical fiber coiling
Optical fiber in journey carries out tension force, is the key point for ensureing that the fiber stress of fiber optic loop is stable, and the tension force of optical fiber is
A significant consideration in optical fiber coil winding machine development process.
Traditional optical fibre gyro coiling machine, because mechanical structure is improper, cause it is low around ring precision, and be unable to do without manual intervention,
Worker leans on eye observation, corrects the arrangement of optical fiber by hand.Due to artificial intervention, the ring laid out has many uncertainties, quality
Low, percent defective is high.
Existing optical fiber coiling machine tension control method has two kinds substantially：One kind is to use potentiometer, according to the position of dancing wheel
Shifting measures fiber tension indirectly, by host computer analysis and Control unwrapping wire wheel speed；Another kind is to measure optical fiber with tension sensor
Power, by host computer analysis and Control unwrapping wire wheel speed.However, fiber tension is adjusted by the change of unwrapping wire wheel speed, it is impossible to essence
Accurate adjustment fiber tension, and the tension system pulley number with tension sensor is more, adds the frictional force with optical fiber,
Have a strong impact on the tension detection of optical fiber.
As can be seen here, in the optical fiber coil winding machine course of work, tension force suffered by optical fiber be dynamic change process, existing method
Simply single change unwrapping wire wheel speed, it is impossible to quick and precisely control fiber tension, the optical fiber ring quality of coiling is bad, the light of production
