Abstract: A connector visual inspection apparatus comprises a rotatable clamp for clamping a connector to be inspected. A first camera of the apparatus is arranged on one side of the clamp for capturing an end face image of the clamped connector along an axial direction of the connector. A computing device calculates an angular difference between an initial loading orientation and a predetermined orientation of the clamped connector according to the captured end face image. A drive device rotates the clamp around an axis that coincides with a central axis of the clamped connector by the calculated angular difference and into the predetermined orientation.
