Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of carbon fiber precursor detection, and in particular relates to an online carbon fiber precursor image acquisition device. Background Art
[0002] Carbon fiber is a new type of fiber material with a carbon content of more than 90% and high specific strength and high specific modulus. Its density is lower than that of aluminum and its strength is higher than that of steel. It has the characteristics of high temperature resistance and corrosion resistance. At the same time, it has the softness and processability of the fiber. It is an important material in the fields of national defense, military industry, aerospace, and civilian equipment. my country's carbon fiber industry started late. After years of development, domestic carbon fiber has achieved good results in performance and application. With the continuous expansion of military demand and the civilian market, high performance, high output, low cost and stability have become the goals pursued by domestic carbon fiber production.
[0003] The quality of carbon fiber is affected by many factors, among which the quality of precursor is the key factor restricting the quality of carbon fiber. It is impossible to produce high-performance carbon fiber without high-quality precursor. Therefore, achieving stable production of precursor quality is one of the problems that need to be solved urgently in the current carbon fiber production.
[0004] The production process of raw silk is complicated. In the production process, the initiators, oligomers and dust particles remaining in the spinning solution will be transmitted or exerted in the subsequent process to form hole defects, and produce hair when tension is applied. At the same time, under the action of tension and stress concentration, stress concentration is also easy to occur, leading to the generation of hair. Finally, the installation accuracy of the transmission machine also has a serious impact on the generation of hair, which is easy to cause the phenomenon of wire sticking and overlapping, thus generating hair. For various hair defects in raw silk production, machine vision-based methods are generally used for detection and evaluation to ensure the production quality of the entire raw silk production line. However, due to the complex spatial structure of the raw silk production line and the fast winding speed of the raw silk, it is impossible to efficiently realize the high-speed acquisition of carbon fiber raw silk images.
[0005] Therefore, in the production of carbon fiber precursor, there is an urgent need for an online carbon fiber precursor image acquisition device with high efficiency, high precision and no influence on the traditional precursor production process. Summary of the invention

[0016] Among them, high-strength glass is set on the holes used for image acquisition and light source lighting to prevent the high-speed running raw wire from entering the module through the holes, ensuring the safety of each module during the high-speed operation of the raw wire;
[0017] Two cooling fans are distributed at the rear end of the shell to dissipate heat for the high-speed industrial camera module and the combined light source module.
[0018] The above-mentioned high-speed industrial camera module uses n Basler ace L model area array high-speed cameras to adapt to the n winding raw yarns moving at high speed in the raw yarn production line, and the area array high-speed camera is fixed on the high-speed industrial camera module frame by bolt connection.
[0019] The above-mentioned high-speed industrial camera module is equipped with a slide rail mechanism for fine-tuning the position of a single camera to ensure that the area array high-speed camera can collect image data of the corresponding raw silk.
[0020] The above-mentioned combined light source module includes a strip-shaped LED light source and a slide rail structure;
