Visual inspection mechanism

Abstract

The invention discloses a visual inspection mechanism. A vibrating plate (13) is installed at one end of the top of a machine table (5), and a scale division rotating plate is arranged at the other end of the top of the machine table (5). A guide rail (9) for conveying parts is arranged between the vibrating plate (13) and the scale division rotating plate and formed by a fixed conveying rail body (9a) and an adjustable conveying rail body (9b) which are arranged side by side, the outlet ends of the fixed conveying rail body (9a) and the adjustable conveying rail body (9b) are both upwards bent to form horizontal sections (9c), and a blowing device (14) is arranged on the lateral side of the outlet end of the guide rail (9). By means of the visual inspection mechanism, pictures of the parts are shot through three CCD cameras from different angles, standard fasteners can be automatically conveyed, inspected, sorted and packaged, the visual inspection mechanism can be used for inspecting the fasteners in various standards, can be suitable for the to-be-inspected parts in different specifications and is good in university and high in automation degree, the device investment is effectively reduced, and the inspection efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of detection devices, and in particular relates to a visual 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 automobile in...

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.
