Tension mechanism adapted for automatic optical fiber winding machine

Abstract

The invention discloses a tension structure used in automatic fiber coiler, composed of a fiber collector, a driver, a transmit box, a fiber discharge wheel, a support base, and a sliding table tension element, a first fiber guider and a second fiber guider, wherein the lower end of the support base via nut and screw is mounted on the sliding table, while the upper end is mounted with the transmit box, the driver is on the transmit box, while a motor and a speed reducer are mounted at the outer back of the transmit box, the accurate shaft of the driver is suspended at the outer front of the transmit box, which is mounted with the fiber discharge wheel, the fiber collector is at one side of the support base, vertically with the fiber discharge wheel, the sliding table is arranged with a plurality of mounting holes for fixing and mounting devices, the tension element, the first and the second fiber guiders via nut and screw are fixed on the sliding table, which guide grooves are in one plane. The inventive tension device has reasonable, compact and simple structure, without reverse dead area, but with stable transmission control, accurate tension control, non-zero-bias in force measurement, digit and closed tension control.

Description

technical field [0001] The invention relates to a tension mechanism suitable for an automatic optical fiber looping machine. Background technique [0002] The fiber optic gyroscope was born in 1976. It is a new type of sensor that uses fiber optic sensing technology to measure the space inertial rotation rate. It has developed into a new mainstream instrument with epoch-making characteristics in the field of inertial technology. Compared with the laser gyroscope, it has higher precision, low cost, small size and light weight. The application prospect of fiber optic gyroscope is very broad. It is not only used for aircraft and ship navigation, missile guidance, and high-precision position control of spacecraft, but also can be used for civilian use in the guidance of high-end cars, as well as robots and automatic control systems, etc. . [0003] The fiber optic ring is the sensing core of the fiber optic gyroscope, and its basic requirements are a large extinction ratio and...

AI Technical Summary

Problems solved by technology

How to wind a high-quality fiber optic ring is very important to the development of fiber optic gyroscopes. There are many winding methods, and the quadrupole symmetrical winding method has the best effect, which is a method commonly used in the world. Manual winding is adopted, and there is no special equipment, so the winding quality cannot be guaranteed

[0004] At present, the tension mechanism used in some automatic optical fiber winding machines has defects such as simple structure, no backlash elimination mechanism, unstable transmission control, low tension control precision, and zero point drift.
