Abstract:
1. A method of assembling a lens module, comprising: providing a lens housing with a cylindrical sidewall extending from a base, wherein the sidewall comprises a pair of ramped surfaces at an end distal to the base; providing a lens barrel with an external sidewall comprising a pair of ramped surfaces; placing the lens barrel in contact with the lens housing with the ramped surfaces of the lens barrel mating with the ramped surfaces of the lens housing; positioning the lens barrel relative to the lens housing to focus a lens mounted in the lens barrel; and with a laser, forming at least two bonds joining the lens barrel to the lens housing, wherein the bonds are located proximate to the mating ramped surfaces; wherein the bonds are located at equidistant points about the periphery of the lens module and each of the bonds overlaps an interface between the lens barrel and the lens housing adjacent the mating ramped surfaces, the bonds including at least a portion of material of the lens barrel and a portion of material of the lens housing; wherein the forming comprises forming at least three bonds at the interface.
