Description

An intelligent device for online quality detection of wool yarn production

Technical Field

The invention belongs to the technical field of woolen yarn production, and relates to an intelligent quality detection device, in particular to an online quality detection intelligent device for woolen yarn production.

Background technique

As people's pursuit of clothing becomes higher and higher, more and more requirements are put forward for fabrics. Correspondingly, more and more functional fabrics are also emerging. Wool is an important raw material for the textile industry. Wool products have the advantages of good elasticity, strong moisture absorption, and good warmth retention. Wool yarn is mostly made of wool, and the production process is long. Due to the process and equipment, the yarn surface often has defects such as hairiness, flaws, broken silk, and twisted silk, which affect the product quality. Since the production equipment pulls out a large number of yarns at the same time, the yarn is thin, and the broken silk is only a few microns, which cannot be observed by the naked eye during the production process. The general detection method is to observe the defects on the outer surface of the bobbin after the yarn is dropped, and measure the whole tube of yarn with the defects on the outer surface. This approach can only cover the whole with a piece, which is not objective enough. In addition, traditional manual monitoring has high labor and time costs, and has the disadvantages of low efficiency, strong subjectivity, poor stability, etc., and manual offline detection affects the automated production of products. Therefore, for the detection of wool yarn fibers, intelligent detection equipment is often used instead of naked eye detection. At present, there are many vision-based online intelligent detection equipment on the market used in the wool yarn production process.

After searching, it is found that a Chinese patent document discloses an online quality detection device and method for PE fiber yarn based on machine vision [Application number: CN202011328287.2; Publication number: CN112485263A]. This online quality detection device and method for PE fiber yarn based on machine vision includes an LED line light source mounted above the PE fiber yarn, an industrial camera is arranged on one side of the LED line light source, and an acquisition trigger control board is connected in parallel with the industrial camera. The industrial camera is connected to the input end of the industrial control computer, and the output end of the industrial control computer is connected to a defect alarm prompter.

The device disclosed in this patent can monitor the hair and yarn on each yarn in real time, store defect images in units of bobbins, and objectively grade the quality of the yarn on the bobbin. The above-mentioned device detects the yarn based on vision, but during the detection process, the hair generated by bobbins floats everywhere, resulting in a large amount of hair in the environment around the equipment, which is easy to cover the surface of the LED line light source or industrial camera, thereby affecting the lighting effect, and also blocking the line of sight, which has a great impact on the detection results. At the same time, the intelligent detection equipment currently on the market can only detect surface defects of woolen yarns, but cannot perform strength detection on yarns. Woolen yarns are easily broken due to insufficient strength. Therefore, the detection range of these intelligent detection devices is too narrow and cannot be applied to a variety of detection occasions.

Summary of the invention
