Abstract: A vehicular camera includes (i) a lens barrel accommodating a lens, (ii) a lens holder having a passageway and (iii) an imager printed circuit board attached to the lens holder with the imager facing the lens. The lens barrel at least partially passes through the passageway of the lens holder when attaching the lens barrel to the lens holder. The imager printed circuit board is attached to the lens holder with the imager facing the lens and optically aligned with the lens. A biasing element urges the lens barrel in a direction outward away from the imager printed circuit board. With the imager printed circuit board attached to the lens holder, the lens barrel is fine adjustable relative to the lens holder. A rear housing attached at the lens holder to encase the imager printed circuit board.

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 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 vehicular camera includes a front camera housing and a lens assembly having cylindrical barrel portion that is at least partially received at the front camera housing. An adhesive is disposed in an uncured state at the front camera housing and/or at the printed circuit board and laterally outboard of the imager. With the adhesive in the uncured state, an air gap exists between the inner surface of the lens and the imager. The adhesive is initially cured from the uncured state to an initially-cured state in an initial radiation curing process that comprises exposure to UV light for a first time period. With the adhesive in the initially-cured state, the front camera housing, with the printed circuit board adhesively attached thereto, is further cured to a further more cured state in a secondary curing process undertaken for a longer time period than the first time period.

Abstract: A vehicular camera for a vehicular vision system includes a PCB having an imager disposed thereat, a lens barrel accommodating a lens, and a lens barrel support structure that protrudes from the PCB and at least partially circumscribes the imager. The lens barrel has an outer surface that extends between the ends of the lens barrel. The outer surface of the lens barrel is adhesively bonded to an inner surface of the lens barrel support structure via adhesive. The outer surface of the lens barrel radially opposes the inner surface of the lens barrel support structure where the adhesive is disposed. With the adhesive in its uncured state and contacting the opposed surfaces, the imager is optically aligned with the lens accommodated at the lens barrel. With the imager optically aligned with the lens, the adhesive is cured to adhesively attach the lens barrel at the lens barrel support structure.

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.

Abstract: A vehicular camera includes a lens accommodated in a lens barrel, a lens holder that accommodates at least part of the lens holder, and a printed circuit board with an imager disposed thereat. The camera utilizes an adhesive to hold the lens optically aligned with the imager. After the lens is optically aligned with the imager, the adhesive is initially curable to an initially-cured state in an initial curing process for an initial-cure time period. The initially-cured adhesive is further curable to a further-cured state in a secondary curing process for a further-cure time period that is longer than the initial-cure time period. As further cured, the further-cured adhesive maintains optical alignment of the lens with the imager for use of the vehicular camera in a vehicle.

Abstract: A method for assembling a vehicular camera module includes providing an imager circuit board and a lens holder. The lens holder includes a lens holding portion and an attaching portion, with the lens holding portion accommodating a lens. The attaching portion of the lens holder includes pins that, when the attaching portion is located at the imager circuit board, are received at least partially through apertures of the imager circuit board. With the pins received at least partially through the apertures, the lens holder is laterally adjusted relative to the imager circuit board and the pins are soldered at the imager circuit board so as to attach the lens holder at the imager circuit board to form an imager assembly. The imager assembly is attached at a camera housing, and a processing circuit board is accommodated at the camera housing and electrically connected to the imager circuit board.

Abstract: A method of assembling a camera suitable for vehicular use includes providing a lens accommodated in a lens barrel, a lens holder, and a printed circuit board with an imager disposed thereat. An adhesive is dispensed to establish a layer of uncured adhesive (i) between the lens barrel and lens holder or (ii) between the printed circuit board and the lens holder. With the lens in focus with the imager and optically center-aligned therewith, the adhesive is initially cured to an initially-cured state in an initial radiation curing process that includes exposure to UV light for a first period of time. The initially-cured adhesive is further cured to a further-cured state in a secondary curing process. The further-cured state is achieved within a second period of time that is longer than the first period of time.
