Optical fiber side surface uniform film coating mask device and film coating method thereof

Abstract

The embodiment of the invention discloses an optical fiber side surface uniform film coating mask device and a film coating method thereof. The optical fiber side surface uniform film coating mask device comprises a rack, wherein a sliding shaft is arranged between a left side plate and a right side plate, a sliding platform is slidably connected to the sliding shaft, a first driving motor is fixed on the left side plate, a second driving motor is fixed on the sliding platform, the first driving motor and the second driving motor are correspondingly in driving connection with clamping assemblies for fixing an optical fiber, guide pipes are arranged on the clamping assemblies, first mask blocks and second mask blocks are arranged between the first driving motor and the second driving motor at intervals, and mask through holes are formed in the first mask blocks and the second mask blocks correspondingly. The optical fiber side surface uniform film coating mask device is simple in structure and small in size, the cylindrical side surface of the optical fiber can be coated with a single-layer film or multi-layer films and film layers with different layered structures, and an independent closed structure is provided, so that the vacuum environment in a coating chamber is not influenced even if a fault occurs in the coating process, and the coating quality is further ensured.

Description

technical field [0001] The present application relates to the technical field of optical fiber coating processing, in particular to a masking device for uniform coating on the side of an optical fiber and a coating method thereof. Background technique [0002] Optical fiber is a kind of fiber made of glass or plastic, which can be used as a light transmission tool. Based on its advantages of large communication capacity, long relay distance, no electromagnetic interference, light weight and small size, it has been widely used in communication. application. [0003] Some signal detection or transmission applications require the optical fiber to have a certain light reflection ability. In order to make the optical fiber have the light reflection ability, the conventional method is to coat the surface of the optical fiber. A key issue in achieving fiber coating is the use of tools to hold the fiber in the coating chamber. Most optical fibers must be wound into coils and packa...

AI Technical Summary

Problems solved by technology

The prior art discloses a rotary fixture that can be used for coating on the side of the optical fiber. The disadvantage of this device is that the device is expensive and the volume is relatively large (the diameter of the coating disc of the magnetron sputtering instrument is about 125mm, and its effective coating diameter is about 75mm. ); In addition, the optical fiber masking process cannot be realized in a vacuum state, and the vacuum experiment environment needs to be destroyed many times, thereby affecting the coating quality
