Problems solved by technology

[0003] In the prior art, the method for curing the optical fiber ring is to use a 600W mercury lamp to irradiate the top of the gyroscope for curing. This method has the following disadvantages: 1. The mercury lamp generates huge heat during curing, which increases the thermal stress in the optical fiber ring, and the strain situation Serious; 2. The uneven irradiation of a single bulb makes the curing intensity of the fiber ring uneven, and the power consumption of multiple bulbs is large; 3. It is necessary to change the angle of the mercury lamp to repeatedly irradiate the ring surface and end surface of the fiber ring during curing, resulting in production efficiency. Too low, production energy consumption is too large

[0004] The overall disadvantage of the existing fiber optic ring curing technology is that it brings additional stress to the fiber ring while curing and the efficiency is too low. The low efficiency means that the production of a gyroscope requires manual participation for multiple curing
