Abstract

The utility model provides a visual detection device with a conveyer, which comprises section bars, a light source assembly, a linear array camera assembly and a belt conveyer. The light source assembly and the linear array camera assembly which are fixed on the section bars are applied for dark field image collections and bright field image collections of a material to be detected. The belt conveyer is applied for adjusting the moving direction and the moving speed of the material to be detected. The moving speed of the belt conveyer is adjusted so as to adapt to the collecting line frequency of a camera. The moving direction of the belt conveyer is changed so as to repeatedly collect the image information. An automatic control on a detection platform can be realized. The workload of an operator is reduced while the operation precision is ensured. By adjusting a large-angle adjusting detection device of one linear array camera, an optimum collection effect image in a bright field condition can be obtained through the adjustment. The obvious flaws in the image and the high contrast pave the way for subsequent operations. An on-site detection environment is simulated to the greatest extent. The horizontal level of the detection platform can be ensured by adjusting four height adjustable structures below a steel support.
