Description

Technical Field

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

[0002] Visual inspection is to use machines to replace human eyes to make measurements and judgments. Visual inspection refers to the process of converting the captured target into image signals through machine vision products (i.e. image capture devices, divided into CMOS and CCD), and transmitting them to a dedicated image processing system, which converts them into digital signals based on pixel distribution, brightness, color and other information; the image system performs various operations on these signals to extract the characteristics of the target, and then controls the equipment action on site based on the results of the judgment. It is a valuable mechanism for production, assembly or packaging.

[0003] The inventor discovered the following defects during the operation of the specific embodiment: When performing visual inspection on cylindrical objects such as bolts, the bolts move inside the rotating disk, allowing the bolts to pass through the visual detector. However, since a portion of the bolt is in contact with the rotating disk, the visual detector cannot effectively inspect the contact surface during visual inspection, which can easily lead to missed inspections.
