Abstract

The invention discloses an auxiliary fiber-discharging device made around an optical fiber, which includes a frame and a fiber-discharging rod; the counterweight is iron, and two electromagnets are symmetrically distributed on the left and right sides of the counterweight, and There are two tension sensors symmetrically distributed on the left and right sides of the machine, and the two tension sensors are respectively connected to the fiber rod through a tension spring; there is a controller on the frame, and the two tension sensors are connected to the controller. After changing the switch, it is connected with two electromagnets, wherein, the left electromagnet, the right tension sensor and the controller form a closed-loop control loop, and the right electromagnet, the left tension sensor and the controller form another closed-loop control loop. The invention can realize the uniform pressure on the optical fiber during the winding process of the optical fiber ring, thereby improving the symmetry of the optical fiber ring, and the automatic degree of optical fiber arrangement is higher, thereby improving the efficiency of optical fiber winding.

Description

technical field [0001] The invention relates to the technical field of optical fiber gyroscopes, in particular to an auxiliary fiber-discharging device for optical fiber wrapping. Background technique [0002] The fiber optic gyroscope is an inertial instrument sensitive to the angular rate of rotation using the Sagnac effect. It is an important member of the inertial navigation field. It has been widely used in aerospace, national defense and military industries, and has gradually been applied in civilian fields such as navigation, surveying and mapping, and oil exploration. The fiber optic gyroscope is composed of a light source, an optical coupler, a Y-waveguide integrated optical device, a PIN detector and a fiber optic ring, among which the fiber optic ring is a device that produces the Sagnac effect. In order to achieve high sensitivity accuracy, the fiber ring needs to have good optical reciprocity, stress distribution symmetry and temperature insensitivity. Arrange...
