Standard fastener detection device

Abstract

The invention discloses a standard fastener detection device. An indexing rotary disc is arranged above a machine table (5). The indexing rotary disc is driven by a stepping motor (9) installed on the machine table (5) to rotate. A first CCD camera (6) is arranged above the edge of the indexing rotary disc. A lens of the first CCD camera (6) is downward. A second CCD camera (7) and a third CCD camera (8) are arranged near the indexing rotary disc. The second CCD camera (7) is close to the third CCD camera (8). A lens of the second CCD camera (7) and a lens of the third CCD camera (8) face the indexing rotary disc. The standard fastener detection device is simple and compact in structure, small in size, low in cost, capable of taking pictures of standard fasteners from different angles with the three CCD cameras and being used for detecting the various standard fasteners, suitable for different specifications of parts to be detected and good in universality, effectively reduces equipment investment and greatly improves detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to a standard fastener detection device. 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 au...

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.
