Problems solved by technology
[0003] However, the debonded fiber optic ring structure also has its disadvantages. The glue for bonding the fiber optic ring and the fiber optic gyroscope structure is manually applied by using a brush. The uniformity of the glue applied in this way cannot be guaranteed. The lack of glue is common, which not only affects the symmetry of the fiber optic ring, but also affects the reliability of the fiber optic gyroscope against vibration and shock. In addition, due to the manual glue brushing method, the repeatability cannot be guaranteed each time. In the case of a general glue gun, the glue is not stable at the beginning of the glue gun, which leads to the situation of excess glue and less glue at the starting point of glue, which eventually affects the consistency of the fiber optic gyroscope.

The invention discloses a device and a method for improving fiber ring adhesion uniformity. The device comprises a base, the base is used for placing a circular fiber gyroscope structure part, a circular groove is formed in the upper end surface of the fiber gyroscope structure part, a glue outlet device is arranged on the upper portion of the base and used for conveying glue into the circular groove and can rotate along the center line of the circular groove, a glue outlet of the glue outlet device is positioned above the circular groove all the time when the glue outlet device discharges glue, a movable baffle plate is arranged on the lower portion of the glue outlet device, and the baffle plate is positioned below the glue outlet of the glue outlet device to stop the glue from flowing onto the circular groove before the glue flows onto the circular groove and after the circular groove is coated with the glue by a round. The device is provided with the baffle plate and the glue outlet device, any repeated coating of the glue is omitted after the circular groove is coated with the glue by a round, so that overlap or vacancy of the glue is avoided, coating uniformity and repeatability of the glue are ensured, and the fiber ring adhesion uniformity is improved.
Description
technical field [0001] The invention belongs to the technical field of fiber optic gyroscopes, and in particular relates to a device and method for improving the bonding uniformity of fiber optic rings. Background technique [0002] Fiber optic gyroscope has the characteristics of all-solid-state structure, wide dynamic range, short start-up time, strong impact resistance and strong anti-interference ability. It is widely used in defense industry fields such as inertial navigation and guidance, attitude control, positioning and orientation. It has also been widely used in civil fields such as orbit detection and oil well inclinometer measurement. The fiber optic gyroscope consists of two sets of components: circuit and optical path. Among them, the optical path component is composed of five major components, and the fiber optic ring is the core component of the five major components. With the development of technology, the structure of fiber optic ring also changes accordin...
