Oil seal spring full-automatic sorting system and method based on image detection method

Abstract

The invention belongs to the image test technology and image processing technical field and relates to an oil seal spring full-automatic sorting system. The system comprises a glass turntable, a collecting and processing component and a sorting component, wherein the collecting and processing component contains a camera with a zoom lens, an LED backlight and a computer; the camera is used to collect the image of an oil seal spring to be detected in a collection area and send the image to the computer; the computer processes and analyzes the collected image of the oil seal spring to obtain the characteristic quantity data and detect judgment of the spring, generate a product sorting signal according to the characteristic quantity data and the detect judgment, and send the sorting signal to the PLC controller; the sorting component comprises the PLC controller, a sub-quality product picking mechanism, a sub-quality product container and the like; and the picking mechanism picks the sub-quality products in a picking area under the control of the PLC controller. The invention also provides a sorting method using the sorting system. The system and method of the invention are simple and efficient, thus the characteristic detection and defect evaluation of the oil seal spring are easy to realize.

Description

technical field [0001] The invention belongs to the field of image testing technology and image processing technology, and relates to an automatic oil seal spring sorting system and method based on an image detection method. Background technique [0002] Oil seal spring is the main component of mechanical seals and an important mechanical component that is indispensable for industrial production and mechanical equipment, such as engine valve oil seals, camshaft oil seals, front and rear oil seals of transmissions, etc. The oil seal spring can isolate the parts that need to be lubricated from the output parts in the transmission parts, so as not to let the lubricating oil leak, which plays a vital role in the cleanliness and environmental protection of the equipment, safe operation and operational reliability. Therefore, the processing quality of the oil seal spring seriously affects its sealing ability, and the online detection and sorting of the oil seal spring is an import...

Problems solved by technology

[0003] For a long time, the quality inspection of oil seal springs requires workers to use their eyes to directly identify and judge key feature points based on experience, or to use rulers or plug gauges for intuitive measurement. Therefore, the measurement accuracy cannot be guaranteed, and the efficiency is very low.

With the development of optical technology, non-contact measurement methods such as digital universal tool microscope, profile projection measuring instrument, and precision optical meter are used for parameters such as oil seal spring diameter. Although the measurement accuracy is high, manual operation is still required. Not suitable for online measurement of oil seal spring production line, often used for quality inspection and random inspection
