Technical Field

The invention belongs to the technical field of ring-wound optical fiber static electricity removal, and particularly relates to a ring-wound optical fiber static electricity removal method.

Background

Because the speed of light passing through the cooling tube in the production process is very high, and the path through which the optical fiber can pass in the cooling tube is very narrow, the optical fiber passing through the cooling tube at high speed in the production process can be scraped with the wall of the cooling tube by a little bit of shake to influence the quality of the optical fiber, and fiber breakage can be caused seriously. The optical fiber is shaken due to various reasons, and the light is shaken possibly due to airflow, static electricity, tower body vibration, artificial reasons and the like, wherein the phenomenon that the optical fiber is shaken or deflected due to the static electricity is inevitable, so that the optical fiber is easy to scratch or break, the coating quality is possibly influenced, and the normal production progress is influenced.

The winding process of the optical fiber ring is to wind the optical fiber on a winding tool according to a specified winding method. The tension of the wound fiber and the arrangement precision of the optical fiber need to be accurately controlled in the winding process. The optical fiber mainly comprises two parts of glass and a coating layer, and can rub with objects such as guide wheels and plastics to be charged with static electricity during the production process and the use process (such as wire winding, rewinding, fiber splitting, ring winding and the like). Since the repulsion or attraction between static electricity may cause fluctuation of tension and reduction of the alignment accuracy of the optical fiber, and may even bring about a risk of fiber breakage, it is necessary to remove static electricity from the optical fiber during the winding process.
