Indexing rotary disc and sorting mechanism for standard fastener detection

Abstract

The invention discloses an indexing rotary disc and sorting mechanism for standard fastener detection. The indexing rotary disc is arranged above a machine table (5). A first CCD camera (6) is arranged above the edge of the indexing rotary disc. A second CCD camera (7) and a third CCD camera (8) are arranged beside the indexing rotary disc. A disengagement prevention baffle (9) surrounds a half of the periphery of the indexing rotary disc. A sliding way (10) for containing parts is further arranged beside the indexing rotary disc. A release fork (11) is arranged beside the inlet end of the sliding way (10). The outlet end of the sliding way (10) is bifurcated into a first flow division channel (10a) and a second flow division channel (10b). A sorting shutter (13) is arranged at the bifurcation position of the outlet end of the sliding way (10). According to the indexing rotary disc and sorting mechanism for standard fastener detection, standard fasteners can be prevented from being disengaged, the parts to be detected can be automatically sorted through the sorting mechanism according to types, and the indexing rotary disc and sorting mechanism have the advantages of being simple and compact in structure, small in size, high in sorting speed and detection efficiency, and the like.

Description

technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to an indexing turntable and a sorting mechanism for standard fastener detection. 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 industri...

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.
