Standard fastener detection system based on machine vision

Abstract

The invention discloses a standard fastener detection system based on machine vision. A vibrating disk (19) 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 (15) for conveying parts are arranged between the vibrating disk (19) and the rotary indexing disk, the guide rails (15) are composed of the fixed conveying rail (15a) and the adjustable conveying rail (15b) which are arranged side by side, both the outlet end of the fixed conveying rail (15a) and the outlet end of the adjustable conveying rail (15b) are bent upward to form horizontal segments (15c), and an air blowing device (20) is arranged on the lateral side of the outlet ends of the guide rails (15). According to the standard fastener detection system based on machine vision, the pictures of parts can be taken through three CCD cameras from different angles, standard fasteners can be conveyed, detected, sorted and packaged automatically, and the standard fastener detection system based on machine vision can be used for detecting various standard fasteners and sorting parts through a sorting device according to categories and is high in sorting speed, automation degree and detection efficiency.

Description

Technical field [0001] The invention belongs to the technical field of detection devices, and specifically relates to a standard fastener detection system based on machine vision. Background technique [0002] In recent years, foreign countries have done a lot of research on quality inspection using machine vision technology, and have obtained many important results. Visual inspection has the advantages of non-contact, fast speed, high precision, and strong anti-interference ability. It has important application prospects in modern manufacturing. At present, it is getting more and more in the fields of machining accuracy inspection, workpiece size measurement, product inspection, etc. Widely used, visual inspection technology provides an ideal means for solving online measurement problems. In the 1980s, the American National Bureau of Standards made a prediction based on surveys: in the future, 80% of industrial inspection work will be completed by visual inspection technology. ...

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.
