Description

TECHNICAL FIELD

[0002] Optical fiber ring is the core element of optical fiber gyroscope, and the performance of optical fiber ring directly affects the precision and stability of the gyroscope and other important indicators. The full-temperature performance of the optical fiber ring directly affects the full-temperature indicators of the optical fiber gyroscope.

[0003] An important factor that determines the temperature performance of the optical fiber ring includes the control of the amount of winding glue during the winding process of the optical fiber ring. The existing automatic winding machine basically uses a manual dispensing machine. When the amount of winding glue decreases to a certain extent, the operator needs to manually control the addition of a certain amount of glue. This will result in a significant increase in the amount of optical fiber glue attached when the glue is first added, and the amount of optical fiber glue attached gradually decreases as the winding consumes glue until the next manual control of glue addition. There are also some automatic dispensing systems. The dispensing machine basically uses a glue needle. The needle is below the fiber passing glue tank. During the winding process, the optical fiber passes through the glue tank to meet the glue demand of the winding. Even though this equipment has introduced automatic control, the glue is a fluid, and the glue is always added in drops. This scheme also has the disadvantage of uneven optical fiber glueing.

The end of the glue applying brush 22 connected to the glue guide pipe 21 extends into the glue applying pipe, and the middle part of the glue applying brush 22 is provided with a glue outlet hole 23. In the implementation, the glue applying brush 22 is made of carbon fiber material, so that when the glue flows into the glue outlet hole 23 of the glue applying brush 22, the glue can be quickly and uniformly immersed in the glue applying brush 22, and the consistency of the glue applying process is improved. In the processing process, the glue guide pipe 21 comprises a small-diameter section connected to the glue outlet pipe 3 and a large-diameter end connected to the glue applying brush 22, and the small-diameter section and the large-diameter end are connected through a tapered section; the end of the glue applying brush 22 connected to the glue guide pipe 21 extends into the large-diameter end; in this way, the glue guide pipe 21 can increase the contact area of the glue and the glue applying brush 22 after changing the diameter, so that the glue can be better injected into the glue applying brush 22.
