Method, device and storage medium for wool detection of carbon fiber warp knitted fabric

Abstract

The invention discloses a method, a device and a storage medium for detecting filaments of carbon fiber warp knitted fabrics. A preset algorithm is used to convert a picture into grayscale image data, and then an average filtering process is performed to make the image smoother. In the carbon fiber cloth surface area, the black area becomes lighter and the white color becomes darker after filtering, that is, the gray value of the pixels in the black area changes from small to large; when the change exceeds a certain set range, the excess area is selected, and the gray scale is filtered out. The pixels whose value difference is greater than the preset offset form several detection areas; the cyclic structure area at the edge of the detection area is removed by the preset erosion circle area, so that the cloth surface features are clearer, and then the detection area is re-screened. Whether it is a wool area is determined by the number of pixels contained in each detection area; online intelligent detection of carbon fiber cloth wool is realized through electronic equipment, which improves the detection accuracy and saves a lot of manpower and material resources.

Description

technical field [0001] The invention relates to the technical field of carbon fiber production, in particular to a method, device and storage medium for wool detection of carbon fiber warp knitted fabrics. Background technique [0002] Carbon fiber not only has the inherent properties of carbon materials, but also has the soft and processable characteristics of textile fibers. Carbon fiber is a black flat yarn, which is brittle and easy to fluff; the production of carbon fiber sheet requires carbon fiber to be woven into resin and then thermoset. [0003] The carbon fiber warp knitted fabric is woven with a bundle of carbon fiber warp yarns and glass fiber weft yarns, so that the expanded carbon fiber warp yarns are divided into multiple carbon fiber bundles in the weft direction. On the surface of the woven carbon fiber fabric, the glass fiber weft yarns are uniformly distributed along the warp direction and are fixedly connected by the binding yarns arranged in the warp d...

AI Technical Summary

Problems solved by technology

[0004] During the production and transportation of carbon fiber fabrics, the carbon fibers and the rollers rub against each other, which is easy to fluff and produce wool. If wool appears on the carbon fiber fabric, it will affect the strength and quality of the carbon fiber fabric.

Manual inspection is not suitable for production lines with a high degree of automation, and the detection rate is very low, so online inspection of fabrics is required during the production process
