A kind of cutting method of hard optical fiber

Abstract

The invention discloses a cutting method of a hard optical fiber. Firstly, a laser is used to preliminarily cut the optical fiber to form a cutting mark, and then a cutting knife is used to cut the optical fiber along the cutting mark. The cutting method of this hard fiber optic fiber is divided into two cuts, and the laser is used for preliminary cutting and then the cutting knife is used to quantify the depth and width of the fiber optic fiber port; it avoids burrs on the cross section caused by manual cutting in the traditional method, and improves the quality of the cutting process after cutting. The flatness of the section of the fiber optic fiber, thereby improving the accuracy of the length of the cutting wire, from the traditional method of 0.5 ~ 1mm deviation to within 0.1mm, the accuracy is increased by more than 5 times; and the whole process adopts automatic feeding and automatic feeding to cut the fiber optic fiber, Thereby reducing the labor intensity and improving the cutting efficiency. This invention is used in the field of hard optical fiber processing and manufacturing.

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 cutting length of the same type of optical fiber will have a large deviation, which is about 0.5-1mm; (3) The labor intensity is high and the cutting efficiency is low; (4) The end surface of the short wire that is skimmed off is uneven and has burrs; (5) During the process of grasping and skimming by hand, the optical fiber wires are squeezed and worn each other, which affects the surface quality of the wire, and then affects the product quality
