Concentricity detection system
A concentricity detection system is adapted to detect a concentricity of an annular component. The concentricity detection system includes a support base having a recess on a top surface, a transparent plate received and positioned in the recess, a vision detection device located above the support base and facing the transparent plate, and a backlight source located below the support base and facing the transparent plate. The annular component is disposed in the recess of the support base and supported on a top surface of the transparent plate. The vision detection device is configured to detect the concentricity of the annular component supported on the transparent plate. A through hole is formed in a bottom portion of the recess and a light from the backlight source passes through the support base via the through hole and the transparent plate to provide backlighting for the annular component.
