Description

Technical Field

[0001] The utility model relates to the technical field of research and development of a dual 4CH optical fiber array+MT production process, and in particular to an optical fiber cutting device. Background Art

[0002] After the optical fiber is processed into a product, it must be cut according to the needs to facilitate subsequent assembly and use. The currently known method for cutting the optical fiber length is: first measure the optical fiber to be determined with a ruler, mark the cutting position with a oil pen, and then cut it with optical fiber cutters.

[0003] The disadvantages of this fixed-length method are as follows: First, measuring the required length and marking the cutting position with a ruler are determined by the human eye, resulting in an inevitable error of 0.2mm to 0.5mm, affecting the processing accuracy of subsequent steps. Second, marking the cutting position with a marker is less accurate. When cutting manually, the wire cutters must be aligned with the scale before cutting. Both steps will cause operator error, resulting in a deviation of approximately 0.1mm to 0.2mm. This error will lead to low processing efficiency. Utility Model Content
