Camera module, manufacturing method thereof, and manufacturing method of glass therefor

A camera module, comprising:

• a camera lens including:
• a carrying frame having an alignment slot;
• a sensor chip corresponding in position to the carrying frame;
• and
• at least one optical lens assembled to the carrying frame, wherein the at least one optical lens and the alignment slot are arranged above the sensor chip;
• and
• an alignment glass sheet assembled in the alignment slot of the carrying frame along an assembling direction, wherein the alignment glass sheet has an asymmetric shape, and the alignment glass sheet and the alignment slot have only one assembling orientation therebetween along the assembling direction, and wherein the alignment glass sheet has an alignment chamfer engaged in a corner of the alignment slot, the corner corresponding in shape to the alignment chamfer.

A manufacturing method of a glass for a camera module, comprising:

• a preparing process implemented by providing a filter glass board that is defined into a plurality of groups each having four unit regions that are in a matrix arrangement and that intersect at a target point;
• a removing process implemented by removing a predetermined segment of each of the groups to enable each of the four unit regions to have an asymmetric shape, wherein, in each of the groups, the predetermined segment encompasses the target point and is arranged on the four unit regions, and the four unit regions each having the asymmetric shape are arranged in 4-fold rotational symmetry with respect to the target point;
• and
• a slicing process implemented by slicing the filter glass board to separate the unit regions of the filter glass board from each other, wherein each of the unit regions having the asymmetric shape is defined as one of a plurality of alignment glass sheets that has an alignment chamfer corresponding in position to the predetermined segment.
