LENS DRIVING APPARATUS AND METHOD FOR MANUFACTURING THE SAME

摘要

A lens driving apparatus includes a spring suspension system and an electromagnetic force generator. The spring suspension system may include a pair of leaf springs, a stationary rigid body sandwiched between the pair of springs, and a lens holder suspended by the pair of springs within a central bore of the rigid body. The electromagnetic force generator may include a coil holder holding a coil and a magnet holder holding at least one magnet. The spring suspension system and the electromagnetic force generator are connected to and spatially separated from each other by a spacer. A method for manufacturing a lens driving apparatus is also disclosed.

1. A method for manufacturing a lens driving apparatus comprising:
(a) separately forming a panel of spring suspension systems connected to one another by a plurality of first bridges, each spring suspension system comprising a pair of leaf springs, a stationary rigid body sandwiched between the pair of leaf springs, and a lens holder suspended by the pair of leaf springs within a central bore of the rigid body; (b) separately forming a panel of electromagnetic force generators connected to one another by a plurality of second bridges, each electromagnetic force generator comprising a coil holder holding a coil and a magnet holder holding at least one magnet; (c) stacking the panel of spring suspension systems and the panel of electromagnetic force generators together by a single-directional vertical assembly process; and (d) cutting the plurality of first and second bridges to produce a plurality of lens driving apparatuses, wherein the spring suspension system and the electromagnetic force generator are connected to and spatially separated from each other by a spacer.
