[0002] In recent years, composite materials have been widely used in aviation, transportation, machinery, electronics, medical treatment, automobiles, chemicals, wind power, construction and other fields. High-performance fibers are ideal reinforcements for advanced composite materials. The development and application of aramid fibers, carbon fibers, glass fibers, and basalt fibers have greatly promoted the development of the field of materials science and have been favored by people. The scope of application is also constantly expanding. Composite-grade glass fibers are mainly used to reinforce thermoplastics. Due to its good cost-effectiveness, it is particularly suitable for composite with resins as reinforcement materials for automobiles, trains, and ship hulls. The linear density of glass fiber is an important quality indicator of glass fiber products. If the linear density deviation is large, it will affect the stability of the glass fiber content and product strength in the terminal composite product. Therefore, before packaging and warehousing of glass fiber products, it is necessary to cut a certain length of yarn from the glass fiber yarn to test whether the linear density is qualified.

[0003] At present, the common method in the market to test the linear density of glass fiber by cutting a certain length of yarn is manual shearing or mechanical cutting. Manual cutting is time-consuming and labor-intensive, and the efficiency is very low. In addition, the error of the cut yarn length is large, which affects the accuracy of linear density detection and causes misjudgment of product quality.
