Patent ID: 7876512

Claim:
An apparatus for assembling a lens module, the lens module comprising a lens barrel with a first principal axis and at least one optical element received therein, the apparatus comprising: an element-grasping member configured for grasping the at least one optical element and mounting the at least one optical element into the lens barrel, the element-grasping member having a second principal axis; an assembly station having a support surface; and two guiding members, each comprising: a stationary element fixedly positioned on the support surface; a movable element and an elastic element positioned between the stationary element and the movable element, the movable element comprising: a positioning surface configured for pressing the element-grasping member; and a clamping surface configured for pressing the lens barrel; wherein the two corresponding clamping surfaces of the two respective movable elements cooperatively define a first receiving space receiving the lens barrel, with the clamping surfaces contacting an outer surface of the lens barrel, and the two corresponding positioning surfaces of the two respective movable elements cooperatively define a second receiving space receiving the element-grasping member, with the positioning surfaces contacting an outer surface of the element-grasping member, such that the first principal axis of the lens barrel is aligned with the second principal axis of the element-grasping member.
