Description

Technical Field

[0001] The utility model belongs to the technical field of visual inspection machines, and in particular relates to a visual inspection machine with a fixed function. Background Art

[0002] The visual inspection machine uses machine vision technology to inspect the appearance of the workpiece. Specifically, it uses a CCD camera (or other image capture device) to convert the inspected target into an image signal and transmit it to a dedicated image processing system to perform detailed inspection and measurement of the workpiece's appearance.

[0003] However, when inspecting a workpiece, the existing visual inspection machine can only perform appearance inspection on a certain position of the workpiece, but cannot perform appearance inspection on different positions of the workpiece. Once the defect on the workpiece is outside the inspection range, it is easy to be missed, resulting in a significant reduction in the inspection effect.

[0004] Therefore, it is necessary to provide a visual inspection machine with fixed functions to solve the above problems. Utility Model Content
