Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber coating machines, in particular to a liquid level lighting device for optical fiber coating machines. Background Art

[0002] Optical fiber is a hard and brittle material, and cracks are easily generated on the surface, which may lead to fiber breakage. Coating is an essential step in the optical fiber processing. Fiber coating is to apply a layer of glue on the exposed optical fiber and then solidify it, so as to increase the mechanical strength and protect the bare optical fiber and the optical fiber fusion point.

[0003] However, the existing optical fiber coating technology is to place the bare optical fiber into the groove of the quartz mold, inject photosensitive glue, and cure the glue under ultraviolet light to achieve optical fiber coating. However, in this process, the amount of glue injected needs to be precisely controlled, and the glue needs to just cover the stripped optical fiber. Since the coating glue is highly viscous and has poor fluidity, the amount of glue poured by the peristaltic pump is difficult to control by the machine itself. At this time, the operator is required to observe the injection of glue in real time. When the amount of glue injected is insufficient, the operator is required to manually control the coating machine to increase the glue. In addition, since the quartz mold is located inside the machine in a closed environment, it is difficult to observe the liquid level of the glue with the naked eye under the irradiation of natural light from the outside, and the amount of glue injected cannot be accurately controlled, which not only affects the processing efficiency of the optical fiber coating, but also affects the processing quality of the optical fiber coating.
