METHOD FOR ASSEMBLING MINIATURE CAMERA ACTUATOR FOR ALIGNING OPTICAL AXIS OF LENS, AND METHOD AND DEVICE FOR ALIGNING OPTICAL AXIS OF LENS OF MINIATURE CAMERA ACTUATOR

摘要

The present invention relates to a method for assembling a miniature camera actuator for aligning the optical axis of a lens, and to a method and device for aligning the optical axis of the lens of a miniature camera actuator. The method of the present invention for assembling a miniature camera actuator for aligning the optical axis of a lens involves positioning a spacer on the top portion of a moving part to compensate for hand shaking, and then measuring the degree of parallelization of the lens, tilting the moving part with respect to the spacer in order for the optical axis of the lens and an image sensor to become perpendicular, and coupling the moving part to the spacer so as to be horizontally movable. The method of the present invention for aligning the optical axis of the lens of a miniature camera actuator involves estimating the degree of parallelization of the lens mounted on the actuator, manufacturing the lower portion of the actuator such that the optical axis of the lens and the image sensor are perpendicular according to the degree of parallelization of the lens, and mounting the actuator on a camera base on which the image sensor is mounted.
