Mechanism for detecting standard fastener

Abstract

The invention discloses a mechanism for detecting a standard fastener. An indexing rotating plate is arranged above a machine stand (5), a first CCD camera (6) is arranged above the edge of the indexing rotating plate, and a second CCD camera (7) and a third CCD camera (8) are arranged by the side of the indexing rotating plate; an anti-dropping baffle plate (9) half surrounds the periphery of the indexing rotating plate; a slide-way (10) is also arranged by the side of the indexing rotating plate; a guide rail (12) is arranged on one side of the indexing rotating plate, the guide rail (12) is obliquely arranged in a way that an inlet end is higher than an outlet end, and the guide rail (12) is composed of a fixed conveying rail (12a) and an adjustable conveying rail (12b) which are arranged side by side. A component can be photographed by the three CCD cameras in different angles, the mechanism can be used for detecting different standard fasteners, and the mechanism is applicable to different to-be-detected components of different specifications while the standard fastener is prevented from dropping. The mechanism has the characteristics of simple and compact structure, small size, low cost, good universality, high automation degree, high detection efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to a mechanism for detecting standard fasteners. 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 a...

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.
