A Production Platform for Identifying Carbon Fiber Abnormalities in Preoxidation Furnaces

Abstract

The invention discloses a production platform for identifying abnormalities of carbon fibers in a pre-oxidation furnace. The platform includes: a pre-oxidation furnace, carbon fiber tow, and a drafting device. The carbon fiber abnormality device, wherein: the system for collecting carbon fiber images includes: an image acquisition mechanism, a light source supply mechanism, an image preprocessing module, and an industrial computer; The abnormal position information of the carbon fiber tow image is transmitted to the device for removing the abnormality of the carbon fiber; the device for removing the abnormality of the carbon fiber is used to shear the carbon fiber tow according to the abnormal position of the carbon fiber tow image; the platform can be used in a pre-oxidation furnace with severe atomization Accurately locate the abnormal position of broken or skipped carbon fiber tows; at the same time, it can quickly eliminate broken or skipped carbon fiber tows to ensure the production quality of carbon fiber tows.

Description

technical field [0001] The invention is mainly applied in the technical field of fiber detection, and in particular relates to a production platform for identifying abnormalities of carbon fibers in a pre-oxidation furnace. Background technique [0002] As an advanced PAN-based composite material, carbon fiber has been widely used in various fields such as aerospace, construction, transportation, and wind power. Carbon fiber has high modulus, high strength, high temperature resistance, corrosion resistance, electrical and thermal conductivity and other superior properties. Everything is divided into two, and carbon fiber also has its weaknesses. It is a brittle material. In the production process, especially pre-oxidation, high and low temperature During the carbonization process, it is very easy to produce some hairs or broken filaments due to fiber breakage, which will lead to a decrease in quality and performance during the preparation process. [0003] During the pre-ox...

AI Technical Summary

Problems solved by technology

[0011] In the carbonization production of carbon fiber, there are many fiber tows and the distance between the tows is small, especially when the fiber tows go back and forth in the oxidation furnace for multiple layers. Filament entanglement seriously affects the stability of production. In order to detect broken filaments in production in time, a broken filament detection device needs to be installed directly under the exit of each layer of fiber running.
