A method for stripping an optical fiber coating layer and an isolating device

Abstract

The invention discloses a method and an isolating device for optical fiber coating layer stripping. The method comprises the following steps: setting up two knife edge isolating devices on an optical fiber, the knife edge isolating device being formed by a blade and a mounting rack; the blade being arranged on the mounting rack, the optical fiber passing through the blade, the distance between the two knife edge isolating devices being length of a to-be-stripped optical fiber coating layer; blowing hot air to the optical fiber coating layer between the two knife edge isolating devices, until the fiber coating layer of the part completely falls off, stopping blowing the hot air; and then performing ultrasonic cleaning on the optical fiber, using nitrogen to dry, to complete stripping of the optical fiber coating layer. Just hot air is used to completely blow the optical fiber coating layer off, and the device and the method are convenient and fast and have no pollution. The knife edge isolating devices are used to isolate, to ensure a separated end face of the optical fiber coating layer to be smooth.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to a method and device for stripping an optical fiber coating layer. Background technique [0002] Existing optical fiber coating stripping methods mainly include mechanical, chemical immersion pickling and thermal stripping. Common mechanical coating stripping methods mainly use wire strippers and blades to cut and scrape off. However, this stripping method is likely to cause serious scratches or scratches on the quartz surface of the optical fiber, so as to affect the mechanical strength and service life of the optical fiber. In addition, the wire stripper cannot accurately control the stripped length when stripping the coating layer of the optical fiber, and the stripped length has poor consistency. Chemical solvent immersion pickling method strips the optical fiber coating layer, the solvent configuration is complicated, and the safety of the operation process is not hi...

AI Technical Summary

Problems solved by technology

Although the stripping method is simple to operate, there are still defects caused by mechanical stripping, including the uneven stripped cut surface of the optical fiber coating, the difficulty of precisely controlling the stripped length, and the serious scratches on the quartz surface of the optical fiber.
