Dust removing device for optical fiber diameter measuring instrument

Abstract

The invention discloses a dust removing device for an optical fiber diameter measuring instrument. The dust removing device comprises an end cover, wherein a fiber through hole is formed in the centerof the end cover. At least two air inlets are formed in the outer wall of the end cover, the air inlets communicate with air flow channels in the end cover, and the air flow channels communicate withair outlets. The end cover is internally provided with the air flow channels corresponding to the air inlets respectively and provided with the air outlets corresponding to the air flow channels respectively. Each air flow channel is internally provided with an air flow conversion component, and the air flow conversion components divide the airflow channels into first air flow channel bodies andsecond air flow channel bodies. The first air flow channel bodies and the second air flow channel bodies communicate with the air inlets and the air outlets respectively. The end cover is internally provided with adsorption channels communicating with the second air flow channel bodies and communicating with the fiber through hole. The ventilation aperture of the air flow conversion components issmaller than that of the first air flow channel bodies. The dust removing device for the optical fiber diameter measuring instrument is used for removing dust and impurities on the surface of the optical fiber diameter measuring instrument online, performs two-step cleaning on online drawn optical fibers and core rods in the extending process, and reduces the influence of the dust and the impurities on the production efficiency and quality of the optical fibers.

Description

technical field [0001] The invention relates to the field of optical fiber and core rod manufacturing, in particular to a dust removal device for an optical fiber caliper. Background technique [0002] The arrival of the 5G era shows that the optical communication industry is constantly developing leanly in line with people's growing needs. The optical fiber industry accepts the opportunities and challenges brought by the development of science and technology, and gradually promotes high-efficiency and low-loss manufacturing methods to meet the harsh market environment. Dust particles and exhaust emissions have always been important factors affecting the efficiency, quality and cost of fiber optic production. For example, during the drawing process, the optical fiber is controlled by a fiber optic caliper. The dust and impurities on the surface of the fiber optic caliper will easily cause a false alarm of the coating diameter after the fiber is drawn, resulting in an emerge...

AI Technical Summary

Problems solved by technology

For example, during the drawing process, the optical fiber is controlled by a fiber optic caliper. The dust and impurities on the surface of the fiber optic caliper will easily cause false alarms of the coating diameter after the fiber is drawn, resulting in an emergency stop of the process. Prolonged alarming will lead to Qualified products are misjudged as defective products, resulting in the miscutting of normal optical fibers, resulting in a large amount of waste, and the problem of false alarms caused by the diameter measuring instrument if the dust is not dealt with in time during the core rod extension process

Based on this, if the dust and impurities on the surface of the optical fiber caliper are not treated in time, it will not only affect the production efficiency of the optical fiber, but also cause irreversible cost losses.
