On-line detection device and method for knitting needle of hosiery machine based on SVM image sorting

Abstract

The invention discloses an on-line detection device for a knitting needle of a hosiery machine based on SVM image sorting. The device comprises a CCD industrial camera arranged on one side of a workbench of the hosiery machine, a supplement light arranged above the industrial camera, a PC machine connected with the CCD industrial camera, and a single chip microcomputer connected with the PC machine and a motor of the hosiery machine; the invention further discloses an on-line detection method for the state of the knitting needle of the hosiery machine by adopting the on-line detection device.By adopting the method, the state of the knitting needle of the hosiery machine in a normal work state can be accurately and efficiently detected in real time; the detection device is reasonable in design, simple in structure and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of visual detection, and in particular relates to an online detection device and method for hosiery machine knitting needles based on SVM image classification. Background technique [0002] Visual inspection is a modern inspection technology that uses cameras to replace human eyes for inspection. It uses industrial cameras (generally divided into CCD or CMOS) to collect image data of the target, and converts the pixel information of the image data into digital signals. , and extract the target features from the signal, so as to judge the state of the target according to the features. At present, visual inspection has been applied in many fields such as industry, scientific research, military affairs, etc., and plays an increasingly important role in various fields. [0003] Knitted products are closely related to our lives and are an important part of our daily life. The knitting needle is an important par...

Problems solved by technology

At present, Huang Dexiang, Ding Tao and others in China have put forward their own solutions for the detection of knitting needles of different knitting machines, but due to factors such as inconvenient debugging of testing equipment, not intuitive enough, or immature testing methods, they still cannot meet the actual needs of the market.

The 4022 type knitting needle detector produced by German Protechna Herbst company is the only online knitting needle detection device on the market, but it cannot be widely used in the market due to its expensive price.
