Machine vision detection system

Abstract

The invention discloses a machine vision detection system. A vibrating disk (14) is installed at one end of the top of a machine table (5), a rotary indexing disk is arranged at the other end of the top of the machine table (5), guide rails (11) for conveying parts are arranged between the vibrating disk (14) and the rotary indexing disk, the guide rails (11) are obliquely arranged with the inlet ends high and the outlet ends low, both the outlet end of the fixed conveying rail (11a) and the outlet end of the adjustable conveying rail (11b) are bent upward to from horizontal segments (11c), and an air blowing device (15) is arranged on the lateral side of the outlet ends of the guide rails (11). Through the machine vision detection system, parts to be detected can be effectively prevented from disengaging, pictures of the parts can be taken by three CCD cameras from different angles, standard fasteners can be conveyed and detected automatically, the machine vision detection system can be used for detecting various standard fasteners, can adapt to different specifications of parts to be detected and is good in universality and high in automation degree, equipment investment is effectively reduced, and detection efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to a machine vision detection system. Background technique [0002] In recent years, foreign countries have done a lot of research on the use of machine vision technology for quality inspection, and obtained many important results. Visual inspection has the advantages of non-contact, fast speed, high precision, strong anti-interference ability, etc. It has an important application prospect in modern manufacturing industry. With a wide range of applications, visual inspection technology provides an ideal means to solve online measurement problems. In the 1980s, the American National Bureau of Standards made a prediction based on the survey: 80% of the industrial inspection work in the future will be completed by visual inspection technology. [0003] As basic parts, standard fasteners are widely used in many industries of the national economy such as the autom...

AI Technical Summary

Problems solved by technology

[0006] First, the detection mechanism can detect fewer functions, and the scope of application is narrow

For example, thread detection can only detect the presence or absence of tapping, whether the length is sufficient, etc., but cannot detect whether the thread pitch and tooth shape are qualified, and the detection accuracy is not high, and there are still high defective products after detection

[0007] Second, a detection device can only detect one type of part. Standard fastener companies generally produce a variety of parts, such as screws, nuts, bolts, etc. If automatic detection devices are used, multiple sets of different detection devices must be purchased. Device testing, enterprise production investment increased

The detection disk of the existing detection device needs to make a detection disk corresponding to each specification of the part, and the corresponding detection disk should be replaced when the parts of different specifications are to be tested, which causes problems such as increased cost of the detection device and low detection efficiency

[0009] Fourth, the existing detection device only detects defective products, and 1-2 workers are required to pack the parts that pass the test. The problems of work efficiency and labor cost of the enterprise have not been completely resolved.
