[0002] Visual inspection is to use machines to replace human eyes to make measurements and judgments. Visual inspection refers to converting the captured target into image signals through machine vision products, transmitting them to a dedicated image processing system, and converting 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 operation of the equipment on site based on the judgment results.

[0003] After massive searches, it was found that the prior art publication number is CN220804497U, which discloses a turntable product visual inspection device, including a frame, a visual inspection unit, a first discharging conveying unit, a first discharging manipulator unit, a second discharging manipulator unit and a second discharging conveying unit; a turntable fixture is arranged in the middle position on the frame, and the turntable fixture includes a rotating disk installed on the frame, and four storage fixtures are evenly installed on the rotating disk along the circumferential direction.
