Abstract
In a method for assembling a camera module, a sensor module, a lens holder, and a lens assembly are first provided. The sensor module includes a substrate and a sensor positioned on the substrate. The lens holder is positioned on the substrate and accommodates the sensor. The lens assembly is held in the lens holder. At least one of the lens holder and the lens assembly has a chamfer at an end thereof opposite to the substrate and located between the lens holder and the lens assembly. Then, curable adhesive is applied to the chamfer. The tilt of the lens is adjusted until the lens assembly is optically aligned with the sensor. The curable adhesive is cured.

A method for assembling a camera module, comprising:
- providing a sensor module, a lens holder, and a lens assembly, the sensor module comprising a substrate and a sensor positioned on the substrate, the lens holder being positioned on the substrate and accommodating the sensor, the lens assembly being held in the lens holder such that the camera module is focused, the lens assembly being capable of moving along an optical axis thereof and allowed to tilt relative to the lens holder, at least one of the lens holder and the lens assembly having a chamfer at an end thereof opposite to the substrate and located between the lens holder and the lens assembly;
- applying curable adhesive to the chamfer;
- adjusting the tilt of the lens assembly until the optical axis of the lens assembly coincides with a line perpendicularly passing through the center of the sensor;
- and
- curing the curable adhesive.
A camera module, comprising:
- a sensor module comprising a substrate and a sensor positioned on the substrate;
- a lens holder positioned on the substrate and accommodating the sensor;
- a lens assembly held in the lens holder, at least one of the lens holder and the lens assembly having a chamfer at an end thereof opposite to the substrate and located between the lens holder and the lens assembly, the chamfer having a surface sloped from the end toward the substrate;
- and
- adhesive positioned on the chamfer and between the lens holder and the lens assembly
- wherein the lens holder is tubular and comprises an inner circumferential surface surrounding the lens assembly and a first object-side end surface perpendicularly connecting the inner circumferential surface and facing away the substrate, and the chamfer is positioned at an intersection between the inner circumferential surface and the first object-side end surface;
- the lens assembly comprises an outer circumferential surface, the lens assembly partially extends out of the lens holder from an end of the lens holder opposite to the substrate and comprises a plurality of wings extending from the outer circumferential surface along its radial directions, the wings are coplanar with each other and located slightly above the lens holder, the adhesive fills up the chamfer and contacts with the wings.
A camera module comprising:
- a sensor module comprising a substrate and a sensor positioned on the substrate;
- a lens holder positioned on the substrate and accommodating the sensor;
- a lens assembly held in the lens holder, at least one of the lens holder and the lens assembly having a chamfer at an end thereof opposite to the substrate and located between the lens holder and the lens assembly, the chamfer having a surface sloped from the end toward the substrate;
- and
- adhesive positioned on the chamfer and between the lens holder and the lens assembly;
- wherein the lens assembly comprises an outer circumferential surface facing the lens holder and a second object-side end surface perpendicularly connecting the outer circumferential surface and opposite to the substrate, and the chamfer is positioned at an intersection between the outer circumferential surface and the second object-side end surface.
