Abstract: A focus-adjustment apparatus which can be applied during manufacture of camera modules includes a rotation mechanism, a drive mechanism, an elevating mechanism, an optoelectronic chip, and a lens module. The rotation mechanism includes a container and movable latch rods therein. The drive mechanism can rotate the rotation mechanism, and the elevating mechanism with optoelectronic chip attached is under the rotation mechanism. The lens module includes a support element adjacent to the optoelectronic chip, an adjustment structure rotatably disposed on the support element, and a lens above the optoelectronic chip in the adjustment structure. When the elevating mechanism raises the lens module and the drive mechanism rotates the rotation mechanism, at least one of the latch rods rotates the adjustment structure, so as to change the distance between the lens and the optoelectronic chip and achieve correct focus.
