ABSTRACT:
A method for assembling lens modules using laser bonding of external ramped surfaces. The method includes providing a lens housing with a sidewall with ramped surfaces and providing a lens barrel with external ramped surfaces. The lens barrel is positioned in contact with the lens housing such that the ramped surfaces of the lens barrel mate with the ramped surfaces of the lens housing. The lens barrel is rotated to focus a lens on an image sensor. With a laser, the method includes forming at least two bonds at an interface between the lens barrel and the lens housing such as proximate to the mating ramped surfaces. The bonds are located at equidistant points about the periphery of the lens module. The bonds may be circular or may be elliptical such as with a width along the interface that is at least twice the height of the bond.
