Automatic cloth surface defect detection device and cloth surface defect detection method

Abstract

The invention discloses an automatic cloth surface defect detection device. The automatic cloth surface defect detection device comprises a rack, a cloth outlet roller, a cloth winding roller, a platform, an image acquisition mechanism, a driving mechanism and a computer host; a conveying roller set is arranged on the rack, and the conveying roller set conveys cloth from the cloth outlet roller to the cloth winding roller at the other end; the cloth passes through the upper part of the platform which is horizontally arranged; the image acquisition mechanism is arranged on the rack and located above the platform; the image acquisition mechanism is driven by the driving mechanism and can reciprocate in the cloth breadth direction; and the image acquisition mechanism is electrically connected to the computer host. The automatic cloth surface defect detection device and cloth surface defect detection method can be suitable for cloth surface detection with large breadth, the influence caused by cloth conveying shaking is avoided, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of cloth surface detection, in particular to a cloth surface defect automatic detection device and a cloth surface defect detection method. Background technique [0002] In the production of cloth, the defect of the cloth surface is one of the important factors affecting the quality of the cloth, and the inspection of the surface defect of the cloth is an important link in the production of cloth, so the cloth inspection machine appeared. Most of the cloth inspection machines on the market are just tools for transmitting cloth. Due to the complexity of defect detection and judgment, they still rely on manual inspection, which is completely completed by human eyes, which restricts the rapid development of the woven textile inspection industry. [0003] In the prior art, there are also some intelligent defect detection equipment in the experimental stage, which use CCD cameras to detect the cloth conveyed betw...

Problems solved by technology

However, during the transmission process of the fabric, there will inevitably be jitter and wrinkles, which will affect the image signal acquisition of the CCD camera, and it is prone to false detection and missed detection.

Moreover, the width of the cloth often changes, and most of the existing intelligent defect detection equipment is equipped with a CCD camera, which cannot cover the detection work of cloth with a large width.
