Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0021] A fully automatic self-rotating yarn image acquisition device in black box mode, such as figure 1 and image 3 As shown, including the frame body 1, the frame body 1 is equipped with two groups of rollers, respectively the first roller 2 and the second roller 3, so that the yarn moves from the first roller 2 to the second roller 3 direction, and the first roller 2 and the second roller 3 An acquisition mechanism for image acquisition of yarn hairiness is arranged between the two rollers 3 . The collection mechanism includes two yarn clampers 4 that are respectively rotatably connected to the frame body 1. The yarn clamper 4 is an electric clamp, and the rotation axis of the yarn clamper 4 is horizontally arranged, and the two yarn clampers The device 4 is symmetrically arranged between the first roller 2 and the second roller 3, and the frame...

The invention discloses a full-automatic self-rotating yarn image acquisition device in a dark box mode, the key points of the technical scheme are as follows: the full-automatic self-rotating yarn image acquisition device comprises a frame body, wherein a first roller and a second roller are arranged on the frame body, an acquisition mechanism is arranged between the first roller and the second roller, the acquisition mechanism comprises a yarn holder arranged between the first roller and the second roller, a driving assembly arranged on the frame body and driving the two yarn holders to rotate synchronously, an industrial camera placed on the frame and collected images of yarn hairiness, a light source provided on the frame, and a control device provided on the frame, a control device outputs a rotation signal to the driving assembly and controls the industrial camera to collect yarn hairiness images, and the frame body is provided with a cover industrial camera, the light source anda dark box cover corresponding to the yarn. According to the full-automatic self-rotating yarn image acquisition device in dark box mode, the yarn hairiness image can be automatically acquired at multiple angles, the interference light can be reduced, and therefore the length and number of the yarn hairiness can be accurately detected.
Description
technical field [0001] The invention belongs to the textile field, and in particular relates to a fully automatic self-rotating yarn image acquisition device in a black box mode. Background technique [0002] Yarn hairiness is one of the important indicators to measure the quality of yarn in yarn quality inspection. Yarn hairiness has a significant impact on the performance, quality and subsequent processing of yarn. Digital detection of yarn hairiness quantity and length has been extensively researched and developed in recent years. The method has the advantages of rapidity, high efficiency, no human subjectivity and the like. The specific principle is to obtain the image through the equipment for collecting the image, and use the image processing algorithm to obtain the length and quantity of the yarn hairiness through computer processing. [0003] The currently used yarn image acquisition device directly collects the plane image of a single angle of the yarn. Because t...
