Camera module package and method of manufacturing the same
The present disclosure relates to a camera module package and a method of manufacturing the same, and the camera module package includes a front body including a housing, a lens, and a retainer; a rear body disposed behind the front body with an interval therebetween; and a PCB provided with an image sensor mounted between the front body and the rear body. According to the present disclosure, performance can be improved after six-axis alignment of a front body formed of a laser light transmissive molded body, a rear body formed of a laser light absorptive molded body, and a PCB including an image sensor, and a process is simplified, components are simplified, and production costs are reduced.
1. A camera module package for a vehicle comprising:
a front body comprising a housing, a lens, and a retainer;
a rear body disposed behind the front body; and
a printed circuit board (PCB) provided with an image sensor and configured to be mounted between the front body and the rear body, wherein:
the front body is formed of a laser light transmissive molded body,
the rear body is formed of a laser light absorptive molded body,
the front body, the rear body, and the PCB are subjected to six-axis alignment and then laser-welded together, and
the retainer is made of rubber or silicone material.
2. The camera module package of claim 1 , wherein the housing is integrally formed with a barrel to fix the lens and the retainer.
3. The camera module package of claim 1 , wherein the housing further comprises a lens and a spacer configured to adjust an interval of the lens.
4. The camera module package of claim 1 , wherein the housing further comprises a filter configured to block light of an unnecessary wavelength range.
5. The camera module package of claim 1 , wherein the housing further comprises an O-ring configured to block moisture and foreign matter to an inside thereof.
6. The camera module package of claim 1 , wherein a coating agent is applied on an outer surface of the housing to block light from an unnecessary light source.
7. The camera module package of claim 1 , wherein the retainer is mounted at an end portion of a barrel of the housing.
8. The camera module package of claim 1 , wherein the rear body has an open front in a rectangular shape and a mounting space configured to accommodate the PCB therein.
9. The camera module package of claim 1 , wherein the PCB comprises the image sensor configured to convert a light source collected at the lens to an electrical signal and a substrate on which the image sensor is mounted.
10. The camera module package of claim 2 , wherein the housing further comprises a lens and a spacer configured to adjust an interval of the lens.
11. The camera module package of claim 2 , wherein the housing further comprises a filter configured to block light of an unnecessary wavelength range.
12. The camera module package of claim 2 , wherein the housing further comprises an O-ring configured to block moisture and foreign matter to an inside thereof.
13. The camera module package of claim 2 , wherein a coating agent is applied on an outer surface of the housing to block light from an unnecessary light source.
14. A method of manufacturing a camera module package for a vehicle, comprising the steps of:
manufacturing a rear body having an open front and a mounting space formed therein;
mounting a PCB provided with an image sensor in the mounting space of the rear body;
mounting a front body in front of the rear body, the front body comprises a housing, a lens, and a retainer; and
aligning the rear body, the PCB, and the front body and laser-welding the rear body, the PCB, and the front body, wherein:
the front body is formed of a laser light transmissive molded body,
the rear body is formed of a laser light absorptive molded body,
the front body, the rear body, and the PCB are subjected to six-axis alignment and then laser-welded together with a laser beam, and
the retainer is formed of rubber or silicone material.
15. The method of claim 14 , wherein the laser beam is irradiated to only a minimal extent of welding surfaces between the front body, the PCB, and the rear body to laser-weld the front body, the PCB, and the rear body.
