According to one aspect of the present invention, a contactless component-inspecting apparatus captures, using a camera, images of an object to be inspected that is assembled or mounted during a component assembly process and compares the captured image and a previously inputted object image to determine whether the object passes or fails the inspection. The contactless component-inspecting apparatus comprises: a stage unit on which the object to be inspected is mounted, and which fixes or transfers the object to be inspected in/to an inspection location; a lighting unit including a color lighting portion for irradiating the object to be inspected with at least four types of visual light having different wavelength ranges, wherein a first white lighting portion is arranged on the color lighting portion so as to irradiate the object to be inspected with white light, and a second white lighting portion arranged beneath the color lighting portion so as to irradiate the object to be inspected with white light; a camera arranged above the lighting unit so as to capture images of the object to be inspected; an image-processing unit which reads the image captured by the camera so as to determine whether the object to be inspected passes or fails the inspection; and a control unit including a motion controller for controlling the stage unit and the camera unit. |
