Self-adjustment module has been introduced for alignment error compensation in a previous paper. Self-adjustment module guarantees accurate arrangement of lens parts during assembly process in spite of alignment error so that remarkable price reduction and miniaturization of assembly machine could be achieved. But this module can not control lens orientation. Cellular phone camera lens is produced by plastic injection molding process, so lens has other special quality according to the orientation. In this paper assembly machine for lens module is designed to control lens orientation.
