Abstract: A vehicular camera includes a lens disposed at a lens holder and an imager disposed at a printed circuit board. The lens holder is one of (i) attached at the printed circuit board by a cured adhesive and (ii) attached at a holding element by a cured adhesive with the printed circuit board held by the holding element. The adhesive is initially curable in an initial radiation curing process and initially-cured adhesive is further curable to a further cured strength in a secondary thermal curing process. The adhesive is initially cured via the initial radiation curing process after the lens is brought into focus with the imager and is optically center-aligned therewith. When further cured via the secondary thermal curing process, the further-cured adhesive maintains focus and optical center-alignment of the lens with the imager for use of the camera in a vehicle.

Abstract: A vehicular camera includes an imager printed circuit board and a lens having a plurality of optical elements. The lens is held in optical alignment with an imager at the imager printed circuit board via a dual cure one-part, filled adhesive that in its uncured state has an epoxy resin. The adhesive is both UV-curable and thermal-curable. A flexible electrical ribbon cable electrically connects circuitry of the imager printed circuit board with additional circuitry of the vehicular camera. Image data captured by the imager is provided to the additional circuitry of the vehicular camera via the flexible electrical ribbon cable. The additional circuitry includes at least a processor for processing image data captured by the imager and provided to the additional circuitry via the flexible electrical ribbon cable. The vehicular camera, when installed and used in a vehicle, captures image data for use by a vision system of the vehicle.

Abstract: A camera sub-assembly for a vehicular camera includes a lens barrel having a cylinder accommodating a plurality of lens optics, and an annular flange extending radially outward from the cylinder. The cylinder is received in a receiving structure of a lens holder so that an annular attaching surface of the lens barrel is juxtaposed with an annular attaching surface of the receiving structure with a cured adhesive disposed between and contacting both of the annular attaching surfaces. The cured adhesive includes an adhesive material. With the lens optics aligned with respect to an imaging array of a printed circuit board attached at the lens holder, the adhesive material is cured to a partially-cured state via exposure of the adhesive material to ultraviolet light. With the joined lens barrel and lens holder construction at a further curing station, the adhesive material is further cured from the partially-cured state to a more-cured state.

Abstract: A vehicular camera includes a lens barrel, a lens holder and an imager PCB. The lens barrel accommodates a lens and has a threaded inner end. The lens holder has a threaded passageway for threadedly receiving the threaded inner end of the lens barrel. The lens barrel is threadedly attached to the lens holder with a biasing element applying a biasing force at the lens barrel to urge the lens barrel in a direction outward away from the lens holder. The imager PCB is attached to the lens holder with an imager of the imager PCB facing the lens, and the imager PCB is adjusted relative to the lens holder and lens barrel construction to optically align the lens at the imager. After the imager PCB is secured relative to the lens holder, the lens barrel is rotated to adjust focus of the lens at the imager.

Abstract: A method of providing a camera sub-assembly for a vehicular camera includes providing a lens barrel, a lens holder and a printed circuit board, and dispensing an adhesive in an uncured state at one or both of (i) an annular attaching surface at an outer end of a receiving structure of the lens holder and (ii) an annular attaching surface of an annular flange of the lens barrel. With the adhesive contacting both of the annular attaching surfaces, the lens optics are aligned with respect to the imaging array at the printed circuit board by utilizing a multi-axis positioning device. After aligning the lens optics with respect to the imaging array, the adhesive is cured to a first cure level and the lens barrel and the lens holder joined together by the adhesive are moved to a further curing station, where the adhesive is further cured to a second cure level.
