Cutting method of hard optical fiber

Abstract

The invention discloses a cutting method of hard optical fiber. The cutting method comprises the following steps: firstly carrying out primary cutting on optical fiber by using laser, thus forming cutting marks; then cutting the optical fiber along the cutting marks by using a cutting knife. According to the cutting method of the hard optical fiber, disclosed by the invention, cutting is carried out in twice, primary cutting is carried out through the laser, and cutting off is carried out through the cutting knife, so that the depth and the width in a port position of the optical fiber can bequantified; burrs generated on a section due to breaking by hands in a traditional method can be avoided, and the flatness of the section of the optical fiber after cutting can be increased, so that the accuracy of the optical fiber cutting length can be increased, the deviation is reduced from 0.5 to 1 mm in the traditional method to within 0.1 mm, and the accuracy is increased by five times or above; the whole process adopts automatic feeding and automatic charging for cutting the optical fiber, so that the manual labor intensity can be reduced, and the optical fiber cutting efficiency can be increased. The cutting method disclosed by the invention is applied to the field of processing and manufacturing of the hard optical fiber.

Description

technical field [0001] The invention relates to the field of processing and manufacturing hard optical fibers, in particular to a cutting method for hard optical fibers. Background technique [0002] The optical fiber panel is an optical fiber image transmission component made of special glass optical fiber. It is drawn from a preform tube into a small-sized optical fiber, and then undergoes repeated arrangement, combination, and re-drawing processes, and finally melted and pressed. . Before melting, due to the size limitation of the melting furnace, the drawn hard fiber often needs to be cut into short fibers of fixed size. Each product requires different lengths and quantities of short fibers. For example: a For optical fiber panel products, the length of short optical fiber required is 100 mm, and the quantity is 1200. Then it is necessary to cut a plurality of long hard optical fiber after drawing to obtain 1200 short optical fiber. [0003] The texture of hard optical...

Problems solved by technology

[0004] Using the above method to cut filaments, there are the following problems: (1) The power of the heating wire is not easy to control. According to different wire diameters and materials, it needs to be adjusted appropriately, resulting in the inability to quantify the melting depth and width of the contact between the optical fiber filament and the heating wire; (2) According to the use time and degree of deformation of the heating wire, the
