Weft yarn angle detection method and device based on carbon fibers and storage medium

Abstract

The invention relates to the technical field of composite materials, in particular to a weft yarn angle detection method and device based on carbon fibers and a storage medium, and the method comprises the following steps: image acquisition: taking a plurality of photos in the width direction of a carbon fiber cloth cover; image processing: identifying weft yarn points in each picture according to the color difference between the carbon fibers and the weft yarns, and storing all the yarn points in an array; establishing of auxiliary points : establishing two auxiliary points in the length direction of the carbon fiber cloth cover, and the connecting line of the two auxiliary points is parallel to the length direction of the carbon fiber cloth cover; and angle calculation: respectively connecting yarn points in the array with one of the auxiliary points, calculating an included angle between the connecting line and the length direction of the carbon fiber cloth cover, comparing the maximum value and the minimum value of the included angle with a threshold range of a preset angle, and judging whether the angle requirement is met or not. The carbon fiber production process is monitored in real time, the weft laying angle is guaranteed, and therefore the product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a carbon fiber-based weft angle detection method, device and storage medium. Background technique [0002] The warp yarn is the yarn in the direction parallel to the selvedge in the woven fabric, and the weft yarn is the yarn at a certain angle to the selvedge in the woven fabric. The warp yarn and the weft yarn are interlaced to form the fabric surface. In the process of carbon fiber fabric production, in order to achieve the production Needed, for different cloth surfaces, the angle of weft yarn laid on it is often different, sometimes it is 0 degrees, sometimes it is 45 degrees, and sometimes it is 90 degrees. When the laying angle is 45 degrees, when the equipment is automatically laying the weft yarn, due to some reasons, the angle of the weft yarn laid can not reach the normal angle, which will affect the subsequent production and reduce the product quality. ...
