ENSEMBLE CAMÉRA ET OBJECTIF VÉHICULAIRE

摘要

A method of manufacturing a vehicular camera, said method comprising providing a front camera housing having a cylindrical aperture having an aperture wall, providing a lens assembly comprising a lens barrel, the lens assembly including optical elements, inserting the lens barrel of the lens assembly at least partially into the cylindrical aperture of the front camera housing, securing the lens barrel of the lens assembly at the aperture wall of the cylindrical aperture of the front camera housing, providing a printed circuit board, wherein the printed circuit board comprises electronic circuity, and wherein the electronic circuitry of the printed circuit board comprises an imager, disposing an adhesive between the front camera housing and the printed circuit board, after disposing the adhesive between the front camera housing and the printed circuit board, adjusting the front camera housing and the printed circuit board relative to each other to achieve lens focus and optical axis alignment of the lens optics relative to the imager, wherein focusing and optical axis alignment of the lens optics relative to the imager is achieved via a multi-axis robot that is operable to adjust the lens optics relative to the imager, initially curing the adhesive via an initial curing process after the lens is brought into focus with the imager, wherein the initial curing process includes exposure to UV light for less than 7 seconds, wherein the adhesive, as cured to the initially-cured state via the initial radiation curing process, is sufficiently strong to (i) attach the printed circuit board relative to the front camera housing and (ii) hold the lens optics in focus and in optical axis alignment with the imager, after the initial curing process, moving the camera to the secondary curing process, further curing the initially-cured adhesive to a fully cured strength in a secondary curing process, and wherein, when further-cured via the secondary curing process, the further-cured adhesive is sufficiently strong to hold the lens assembly in position during use on a vehicle.
