Method and device for performing multi-spectral detection on surface quality of fabrics

Abstract

The invention discloses a method and a device for performing multi-spectral detection on the surface quality of fabrics. The device consists of a contrast image sensor (CIS) array, a multi-spectral LED on-off controller, an image data acquirer, a motor controller, a master controller, a touch screen or keyboard, a display, an inkjet indicator, a communication interface and a printer, wherein the CIS array consists of contact image sensors. The device is characterized in that: the master controller controls the running of a motor in a cloth inspecting machine by the motor controller; the fabrics pass by the CIS array under the drive of a power device of the cloth inspecting machine; every step the motor moves forwards, image data acquisition is performed under the illumination of various spectrums; the master controller identifies image data, stores the information of the positions, types, levels and the like of flaws and foreign yarns, and transmits the information to a monitoring center through the communication interface; the inkjet indicator makes marks at the positions of the flaws and foreign yarns by using ink which is easy to clean; and the printer can output detection reports.

Description

Technical field: [0001] The invention relates to photoelectric detection technology, and also relates to the technical field of textile quality detection, in particular to a method and device for multi-spectral detection of textile surface quality. Background technique: [0002] Textile surface quality inspection is an important part of modern textile production, and occupies an extremely important position in the production process. At present, the so-called automatic cloth inspection machines produced and sold in China still rely on human eyes to judge the quality of textile surfaces. The work is monotonous and labor-intensive, and it is easy to produce false inspections and missed inspections, resulting in quality accidents. [0003] For this reason, it was proposed to use the method of machine vision to detect the surface of textiles. For example, the Chinese invention patent application 200710146114.7 "Continuous material inspection device and method" announced on Janu...

AI Technical Summary

Problems solved by technology

[0004] 1. Since the above-mentioned invention patent only detects the defect or color difference of the inspected material under visible light illumination, and has a single function, when the fabric is mixed with different fibers of the same color, it is difficult for the above-mentioned invention to detect

Foreign fibers are not easy to dye, which makes unqualified products with foreign fibers flow into the subsequent printing and dyeing process, resulting in defective products such as uneven dyeing and printed patterns that cause losses.

[0005] 2. The optical system of the CCD camera needs a wide field of view, so it takes up a lot of space, which is not conducive to the transformation and utilization of existing equipment

[0006] 3. The high price of linear array CCD cameras, especially color linear array CCD cameras, increases the manufacturing cost of equipment, which is not conducive to the promotion and application of patented technologies
