Abstract
A method for manufacturing a camera module. An objective is aligned in relation to an image sensor and is subsequently fixated in terms of position by connecting to a support receiving the image sensor or to a housing surrounding the image sensor. The objective is connected to the support or to the housing via at least two cylindrical pins, the cylindrical pins being in each case placed laterally against the objective and being welded on the one hand to the objective, and on the other hand to the support or the housing. A camera module is also described.
Claims16
A method for manufacturing a camera module, the method comprising:
- aligning an objective in relation to an image sensor;
- and
- fixing, after the aligning, the objective in terms of position by connecting the objective to a support receiving the image sensor or to a housing surrounding the image sensor;
- wherein the objective is connected indirectly to the support or to the housing via at least two cylindrical pins, each of the cylindrical pins being placed laterally against the objective and being welded to the objective and to the support or the housing,
- wherein an axial gap is formed between a circumferential flange of the objective and the housing, so that the objective does not directly contact the housing to provide degrees of freedom enabling a multi-axis alignment of the objective in relation to the image sensor,
- wherein the housing includes a projection, which is a support, having a flat contact surface,
- wherein the fixing is effected indirectly via the cylindrical pins that bridge the axial gap, each of the pins directly contacting a flat contact surface of the circumferential flange of the objective and the flat contact surface of the projection, the flat contact surface of the circumferential flange of the objective being perpendicular to the flat contact surface of the projection,
- wherein when weld seams are placed, the cylindrical pins are pressed in a direction of the flat contact surfaces with the aid of a holding force applied from the outside, and
- wherein a direction of the force approximately corresponds to an angle bisector of the angle enclosed by the flat contact surfaces.
A camera module, comprising:
- an objective;
- and
- an image sensor arranged on a support and surrounded by a housing;
- wherein the objective is connected indirectly, to the support or to the housing, via at least two cylindrical pins, each of the cylindrical pins being welded to the objective and to the support or to the housing,
- wherein an axial gap is formed between a circumferential flange of the objective and the housing, so that the objective does not directly contact the housing, so as to provide degrees of freedom enabling a multi-axis alignment of the objective in relation to the image sensor,
- wherein the housing includes a projection, which is a support, having a flat contact surface,
- wherein the fixing is effected indirectly via the cylindrical pins that bridge the axial gap, each of the pins directly contacting a flat contact surface of the circumferential flange of the objective and the flat contact surface of the projection, the flat contact surface of the circumferential flange of the objective being perpendicular to the flat contact surface of the projection,
- wherein when weld seams are placed, the cylindrical pins are pressed in a direction of the flat contact surfaces with the aid of a holding force applied from the outside, and
- wherein a direction of the force approximately corresponds to an angle bisector of the angle enclosed by the flat contact surfaces.
