A kind of optical fiber ring bonding method

Abstract

The invention designs an optical fiber ring sticking method. The method comprises the following steps: a plurality of rectangular grooves are uniformly formed in an inner winding bearing surface of anoptical fiber ring fiber winding baffle plate; after an optical fiber ring is wound, a plurality of bosses with the same height are formed on a side surface corresponding to the rectangular grooves,and only one boss is formed on the opposite other side surface; a PP film with the same size as the side surface of the optical fiber ring is cut out; the optical fiber ring subjected to rotary curingis arranged front side down on an acrylic resin lower plate with small holes, the small holes are positioned at the bosses, ring winding glue is applied uniformly among the bosses with the same height, the PP film is laid on the surface, an acrylic resin upper plate is placed on the PP film, and the plates are put into an ultraviolet curing box and cured; when the glue is not completely cured, the ring winding glue is applied and cured with a ring body so combination is more tight; the acrylic resin lower plate put at the lower layer can ensure the placing levelness of the ring body, the acrylic resin upper plate put on the upper layer can ensure the levelness of a ring sticking surface, the bonding force between the PP film and the cured glue is small, and the PP film is easy to take off.

Description

technical field [0001] The invention belongs to the technical field of fiber optic gyroscope production, and in particular relates to a method for bonding fiber optic rings. Background technique [0002] The fiber optic gyroscope is an angular velocity sensor based on the Sagnac effect, which has many advantages, such as: high precision, large dynamic range, small size, no mechanical rotating parts, etc. in the navigation system. The sensing part of the fiber optic gyroscope is a fiber ring made of polarization-maintaining fiber. As an important part of the fiber optic gyroscope, the fiber optic ring has a great influence on the accuracy of the fiber optic gyroscope. [0003] In the production process of the optical fiber ring, the ring glue is brushed during the ring winding process, and then cured to form a ring. The fiber optic ring is assembled into a fiber optic gyroscope, and the ring body needs to be glued to the ring holder by glue. Due to the different winding m...

Problems solved by technology

Due to the different winding methods, there will be bosses on the side of the ring body, and the flatness of the adhesive ring surface cannot be controlled
