technical field

The invention relates to a fiber collecting mechanism of an automatic optical fiber looping machine.

Background technique

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. .

The fiber optic ring is the sensing core of the fiber optic gyroscope, and its basic requirements are a large extinction ratio and good reciprocity. 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.

The fiber receiving mechanism of the automatic optical fiber ring machine has to ensure that the optical fiber wound on the optical fiber barrel remains uniform and accurate after adopting a better fiber winding process. In order to solve this problem, the inventors of the present invention provide a counter that can accurately record the number of winding turns by installing a counter on the output shaft of the driving end, thereby improving the winding quality.
