Description

Technical Field

[0001] The present invention mainly relates to the field of visual inspection, and in particular to a multi-angle visual inspection device. Background Art

[0002] Visual inspection uses machines to replace the human eye in measurement and judgment. This involves using machine vision products (i.e., image capture devices, available in CMOS and CCD) to convert captured objects into image signals. These signals are then transmitted to a dedicated image processing system, which converts them into digital signals based on pixel distribution, brightness, color, and other information. The imaging system then performs various operations on these signals to extract the object's features and, based on the resulting analysis, controls the operation of on-site equipment. This is a valuable mechanism for production, assembly, and packaging.

[0003] During the operation of the specific embodiment, the inventors found the following defects:

[0004] When performing visual inspection on cylindrical objects such as bolts, the bolts move inside the rotating disk, causing the bolts to pass through the visual detector. However, since part of the bolt is in contact with the rotating disk, the visual detector cannot effectively detect the contact surface during visual inspection, which can easily lead to missed inspections.

[0005] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Summary of the Invention
