APPARATUS AND METHOD FOR ALIGNING OPTICAL AXES OF LENSES AND ASSEMBLING CAMERA MODULE

摘要

Provided are an apparatus and method of aligning optical axes of lenses and assembling a camera module that are capable of adjusting the optical axes of the lenses. The apparatus for aligning the optical axes of the lenses and assembling the camera module includes a support block to support a substrate at which an image sensor is installed, a displacement sensor to measure a tilted state of the image sensor, a fastener to fasten or loosen fastening components to couple a lens holder to the substrate, and a controller to control a fastening level of the lens holder by the fastener to correct a tilted state according to a measurement result of the displacement sensor. The optical axis of the lens can be rapidly and precisely adjusted and assembled by use of the above described apparatus and method.
