[0001] JIG FOR MARKING ACTUATOR OF CAMERA MODULE [0002]

The present invention relates to a jig for marking an actuator of a camera module. More particularly, the present invention relates to a jig for marking an actuator that supports forming a marking portion on a side surface of an actuator of a camera module.

The camera module is a component that converts an optical signal input through a lens to an electrical signal using an image sensor such as a CCD or CMOS. Camera modules are widely used in devices such as smart phones, mobile phones, tablet PCs, and notebook computers. Recently, with the development of smart car technology, the range of applications as a built-in camera is expanding in various fields such as automobiles.

Generally, a camera module includes an actuator coupled to an upper portion of an image sensor and an image sensor, and a lens portion provided in an actuator and driven up and down. In order to perform functions such as AF and OIS in the camera module, the lens part must be driven effectively by an actuator. The actuator is driven by a voice coil motor, piezo system or the like.

The separately manufactured lens part is mounted in the carrier of the actuator, and the camera module is manufactured by attaching an actuator accommodating the lens part to the upper part of the image sensor.

After completing the assembly of the components, the actuator is marked with the model number, the serial number, and the like on the outer surface of the housing.

1 shows a state in which a character is marked on a housing of an actuator included in the camera module.

The actuator 10 includes a carrier 14 having a lens accommodating portion 16 and a housing 12 having an outer shape. The actuator 12 has a marking portion 18 Is formed. When the actuator 10 includes a VCM (Voice Coil Motor) driving unit, the marking unit 18 may be formed on the surface of the yoke exposed to the outside of the housing 12.

The marking unit 18 may be displayed by printing ink, or may be formed using a laser. In this case, the side surface of the actuator 10 should be disposed and fixed so as to face the laser irradiation apparatus.

However, since the size of the actuator 10 is small, it is not easy to adjust and fix the positions of the plurality of actuators 10 manually. In addition, much of the manufacturing process of the actuator 10 depends on manual operation, which is undesirable in terms of increased productivity and manufacturing cost.
