[0002] As is well known, visual inspection uses machines to replace human eyes for measurement and judgment. Visual inspection refers to the process of converting the captured target into an image signal through machine vision products, which is then transmitted to a dedicated image processing system.

The image system performs various calculations on these signals to extract the target's features, and then controls the on-site equipment based on the judgment results. In the visual inspection process, a lens holder is needed to hold and fix the lens for inspection of the human eye.

When lens height adjustment is needed, a first servo motor drives a first gear to rotate, which in turn drives a second gear and a first rotating rod to rotate. Then, a third... The gear drives the fourth gear to rotate, which in turn drives the lifting block to move upward through the fourth gear and the tooth groove meshing with its tooth surface. Then, when the lens needs to be moved laterally, the second servo motor drives the threaded rod to rotate, which in turn drives the slider to move left and right, thereby adjusting the lateral position of the lens. This facilitates lens position adjustment, and three sets of infrared sensors can accurately locate the position of the slider to confirm the position of the lens.
