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 for assembling an imager assembly for a vehicular camera includes providing a lens barrel that accommodates a lens, providing a lens holder, and providing a PCB with an imager disposed thereat. A cylindrical portion of the lens barrel is disposed in a cylindrical passageway of the lens holder and the PCB is disposed at the lens holder. An adhesive is dispensed to hold the lens optically aligned with the imager. After the lens is optically aligned with the imager, the adhesive is initially cured to an initially-cured state in an initial curing process for an initial-cure time period. The adhesive is further cured to a further-cured state in a secondary curing process for a longer further-cure time period. As further cured, the further-cured adhesive maintains optical alignment of the lens with the imager for use of the imager assembly in a vehicular camera in a vehicle.
Abstract:
A method of assembling a vehicular camera includes providing a printed circuit board and dispensing an adhesive in an uncured state at the printed circuit board. A front camera housing is mated with the circuit board, and the lens optics are aligned with respect to the imaging array at the circuit board by utilizing a multi-axis positioning device operable to translate the circuit board or lens assembly relative to the other along one or more orthogonal translational axes and manipulate the circuit board or lens assembly relative to the other about one or more orthogonal rotational axes. After aligning the lens optics with respect to the imaging array, the adhesive is cured to a first cure level and the joined lens assembly and the front camera housing are moved to a further curing station, where the adhesive is further cured to a second cure level.
Abstract:
A process for providing a vehicular camera and mounting the vehicular camera at a vehicle includes providing a vehicular camera having a camera-locking structure configured for engagement with a vehicle panel-locking structure at a vehicle panel of the vehicle at which the vehicular camera is to be mounted. The vehicular camera is mounted at the vehicle panel by inserting a portion of the vehicular camera through an aperture of the vehicle panel and inserting the camera-locking structure through corresponding portions of the aperture of the vehicle panel, and rotating the camera-locking structure to a locked position, whereby the camera-locking structure is engaged with the vehicle panel-locking structure. With the camera-locking structure engaged with the vehicle panel-locking structure, locking surfaces of the camera-locking structure engage respective locking surfaces of the vehicle panel-locking structure to limit axial movement of the vehicular camera relative to the vehicle panel.
Abstract:
A vehicular camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle includes a lens holder, an imager printed circuit board, a connector printed circuit board and a rear housing. The imager printed circuit board has an imager disposed at a side thereof and is attached to the lens holder with the imager side facing the lens. The imager printed circuit board and the connector printed circuit board are joined together via a pliable material. The rear housing is mated with the lens holder to encase the imager printed circuit board and the connector printed board.

Abstract:
A camera for mounting on a vehicle includes a front housing member having a lens, an imaging element and a circuit board, with the circuit board includes a set of front electrical connectors. A rear housing member mates with the front housing member along a first axis. The rear housing member includes a set of rear electrical connectors that, with the rear housing member mated with the front housing member, directly contact the front electrical connectors without use of a jumper. One set of the sets of front and rear electrical connectors is a set of male electrical connectors and the other set of the sets of front and rear electrical connectors is a set of female electrical connectors. Each female electrical connector has jaw structure including first and second jaws.
Abstract:
A process for providing a vehicular camera includes providing a front housing member and a rear housing member. The front housing member includes a lens member, an imaging element and a circuit board mounted thereat, with the circuit board having at least first and second front housing electrical connectors. The rear housing member includes at least first and second rear housing electrical connectors. The front and rear housing members are positioned so that the first front housing electrical connector aligns with the first rear housing electrical connector and the second front housing electrical connector aligns with the second rear housing electrical connector. The front and rear housing members are joined together to define a camera interior. When the front and rear housing members are joined together, the front housing electrical connectors mechanically contact and electrically connect within the camera interior with the rear housing electrical connectors.
Abstract:
A vehicular camera includes a lens, a printed circuit board and an imager. The lens has a plurality of optical element and is disposed at a lens holder. The imager is disposed at the printed circuit board. The adhesive is initially curable in an initial radiation curing process that comprises exposure to UV light, 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. The initially-cured adhesive, as cured via the initial radiation curing process, holds the lens optically center-aligned and in focus with the imager. After the initial radiation curing process, the lens holder, adhesively attached to one of the printed circuit board and the holding element, is moved to the secondary thermal curing process.
Abstract:
A method of assembling a vehicular camera includes providing a lens assembly having a base portion, a lens barrel and a plurality of optical elements in the lens barrel, and providing a circuit element having a circuit board and an imaging array. An adhesive bead is dispensed at the base portion and/or circuit element. The circuit element is placed at the base portion with the adhesive bead therebetween and the optical elements are aligned with the imaging array via a six axis robotic device when the circuit element is at the base portion and in contact with the adhesive bead. The adhesive bead is cured to a first cure level via exposure of the adhesive bead to ultraviolet light. The assembly is moved to a second curing stage and the adhesive bead is cured to a second cure level via heating the adhesive bead.
