This application relates to a high-precision
visual inspection system and method for product sides, belonging to the technical field of
visual inspection. It includes a worktable, a
light source, a vision camera, and reflectors. The worktable has an inspection area for placing the product. The
light source illuminates the side of the product within the inspection area. The vision camera is positioned above the inspection area. Several reflectors are obliquely arranged on the worktable, each corresponding to a side of the product within the inspection area. The reflectors are located to the side of the corresponding side of the product. When the
light source illuminates the side of the product, the light reflected from the side is reflected by the reflectors to the central area of the vision camera. This application achieves high-precision inspection of all sides of a product under single-vision camera conditions, reducing equipment cost and size.
