Abstract: A lens driving device having an OIS system comprises a movable part equipped with a lens, a fixed part and a driving system for moving the movable part to relative to the fixed part. A plurality of notches are furnished on a frame of the movable part. Each notch extends downward from an upper surface of the frame that, a bottom of the notch is the location where a damping medium is applied. A needle of a damper applying equipment can pass through the notch in a top-to-bottom manner and apply damping medium at the bottom of the notch. In addition, medium curing equipment can apply curing light directly from the top side of the lens driving device for curing the damping medium. Not only the operations for applying and curing the damping medium can be performed in a top-and-down manner and thus decreasing the manufacturing time, but also the placement of the production space between the production trays can be reduced and thus increasing the manufacturing batch.
