Abstract

The invention discloses a part surface quality detection device based on artificial vision, which includes a detection box, a camera, a light source, a controller, a photoelectric switch, a conveying chain, a vacuum suction cup manipulator and a conveying chain driving device, and the CCD camera is provided with two , a camera is arranged above and below the conveyor chain, and the conveyor chain driving device is used to eliminate the vibration generated by the conveyor chain when transporting the product to be tested. Due to the setting of the conveyor chain, it is convenient to hang the tested product to realize the simultaneous detection of the upper and lower cameras. Due to the setting of the regular hexagonal sprocket, it can carry a larger moment and transport heavier items; the second transmission The speed fluctuation of the disc offsets the fluctuation of the conveyor chain speed driven by the regular hexagonal sprocket, thus obtaining a relatively stable conveying speed, eliminating the vibration generated by the conveyor chain during the conveying process, and improving the stability of the product under test.

Description

technical field [0001] The invention belongs to the technical field of component surface quality detection, in particular to a component surface quality detection device based on artificial vision. Background technique [0002] With the development of industrialization, industrial products have already been integrated into all aspects of people's life, industrial production and other fields. In order to detect the surface quality of parts, the method of manual visual inspection was used at first. The manual visual inspection method is inefficient, and it is impossible to make accurate numerical results for the quality of high-precision parts. [0003] At present, the surface defect detection of parts in the prior art has begun to transmit the tested product through the conveyor belt, and a detection device is installed above the conveyor belt for defect detection. [0004] For example, the announcement number is CN107486412A, and the publication date: December 19, 2017. In...
