Embodiment Construction

[0013] As shown in the figure, a CCD detection device of an automatic cloth inspection machine includes a CCD camera 1, a cloth guide roller 2 and a light source. The CCD camera 1 , the cloth guide roller 2 and the light source are arranged in the casing 7 . The cloth 5 is arranged between two cloth guide rollers 2, the light source includes a main light source 3 and a backlight 4, the backlight 4 is arranged on one side of the cloth 5, the CCD camera 1 is arranged on the other side of the cloth 5, the CCD camera 1 and the backlight The source 4 is arranged oppositely, the intersection of the main optical axis of the cloth 5 and the CCD camera 1 is the detection area, and the main light source 3 is arranged between the cloth 5 and the CCD camera 1 . In order to reduce the impact of ambient light on the shooting clarity, the preferred method is: the cloth 5 is horizontally arranged between two cloth guide rollers 2, and the cloth 5 is flattened by the cloth guide rollers 2, and...

Abstract

The invention discloses a charge coupled device (CCD) detection device for an automatic burling machine. The CCD detection device comprises a CCD camera, cloth guiding rollers and light sources. Cloth is horizontally arranged between the two cloth guiding rollers. The light sources comprise a main light source and a standby light source. The standby light source is arranged on one side of the cloth. The CCD camera is arranged on the other side of the cloth, and is arranged opposite to the standby light source. A detection area is formed at a joint between the cloth and a main optical axis of the CCD camera. The main light source is arranged between the cloth and the CCD camera. A connecting line from the main light source and the detection area forms an included angle of 20 to 70 degrees with the plane of the cloth. A distance between the main light source and the cloth is shorter than that between the CCD camera and the cloth. The CCD detection device effectively improves the detection efficiency and increases a flaw detection rate. By the technical scheme, the detection speed of higher than 150 meters per minute can be achieved, the flaw detection rate can be over 96 percent, a fallout ratio can be lower than 1 percent, and false detection can be almost avoided.

Description

technical field [0001] The invention relates to an automatic cloth inspection machine, in particular to a CCD detection device of the automatic cloth inspection machine for detecting weaving defects. Background technique [0002] With the development of automatic monitoring of textile production process and the improvement of yarn and fabric quality, as well as the reduction of series of problems caused by stress in the weaving process of yarn, cloth inspection has also become an important link to improve product quality. The purpose of cloth inspection is to detect fabric defects and mark them. The traditional fabric inspection method in the textile industry is manual cloth inspection. Since manual cloth inspection uses one person and one cloth inspection machine to fully inspect the produced fabrics, it is suitable for all kinds of fabrics. However, the detection speed of manual cloth inspection is relatively slow, generally at 5-20 m / min, and up to 200 defects can be det...
