ABSTRACT:
A stacked actuator assembly has symmetrical actuator arms and spacers stacked on a rotatable sleeve. The assembly may have circuit elements or other elements attached on one side of the assembly. The weight of these elements is counter balanced by a screw or pin mounted on the other side of the assembly. The screw passes through the stacked armature arms and spacers to clamp the arms and spacers relative to each other and prevent them from rotating relative to each other. In addition, the spacers may be position registered relative to each other by registration members molded into the spacers. The registration members in adjacent spacers mate with each other to register the spacers relative to each other. The stacked actuator assembly may be assembled on a jig. The jig has a mounting hole or post to receive the sleeve for the stacked actuator assembly, and it has a post to register the arms when they are stacked on the sleeve. It has a spacer registration member to register the first spacer stacked on the sleeve; thereafter, the additional spacers stacked on the assembly register relative to each other. Alternatively, the jig may have a second post to register the position of the spacer that carries the coil of the voice coil motor.
