Embodiment
Please refer to shown in Fig. 1, present embodiment discloses a kind of camera module 100, and this camera module 100 has etched identity coding sign 110.Identity coding sign 110 is etched on camera module 100, forms an integral body with camera module 100, and identity coding sign 110 is not easy to come off, and can be retained on camera module 100 always, makes this camera module 100 have persistence and follows the tracks of sign.
At length, camera module 100 comprises circuit board 120, is installed on the microscope base assembly 130 of circuit board 120 and is installed on circuit board 120 and the image sensor 140 between circuit board 120 and microscope base assembly 130.Microscope base assembly 130 has metal shell 132, and identity coding sign 110 is etched on metal shell 132, preferably, identity coding identifies 110 laser-induced thermal etchings on metal shell 132, be not easy to come off, can be retained on metal shell 132 always, and conveniently read.
Microscope base assembly 130 comprises described metal shell 132, is wrapped in mount pad 134 and pick-up lens 136 in metal shell 132.Mount pad 134 has the installing hole 1342 of the upper and lower surface of passing, and pick-up lens 136 is installed on installing hole interior 1342.
Camera module 100 also comprises the bracket 150 with accepting groove 152, and accepting groove 152 is recessed to the bottom surface that runs through bracket 150 downwards.Image sensor 150 is fixedly installed in accepting groove 152, microscope base assembly 130 is positioned at a surperficial top of image sensor 140, image sensor 140 is aimed at pick-up lens 136 by installing hole 1342, and another surface label of image sensor 140 is attached on circuit board 120.Certainly, bracket 150 is also fixed on circuit board 120.
Adopt the mode of laser-induced thermal etching, the privileged site at the metal shell 132 of the microscope base assembly 130 of camera module 100, carries out unique identity coding according to certain coding rule, and then laser-induced thermal etching, at assigned address, forms identity coding sign 110.As respectively each camera module 100 carried out to unique identity coding sign 110 according to the specific coding rule of production line.Utilize this identity coding sign 110, can scan and read single camera module 100 details.Preferably, identity coding sign 110 is Quick Response Code sign.Each camera module 100 just has its unique Quick Response Code sign like this, and this Quick Response Code sign can be inquired about the information such as 100 dates of manufacture of camera module batch, then can further read according to database data in background system the information that camera module 100 is more detailed.As: factory setting, the details such as each work station tuning parameter historical record, so that follow-up analysis tracking work.
Camera module 100 also comprises and is fixed on circuit board 120 back to the stiffening plate (not shown) of the another side of image sensor 140.In other embodiments, all right laser-induced thermal etching of identity coding sign 110 is on stiffening plate.Equally, this identity coding sign 110 is also preferably Quick Response Code.So, each camera module 100 has its unique Quick Response Code sign equally, this Quick Response Code sign can be inquired about the information such as 100 dates of manufacture of camera module batch, then can further read according to database data in background system the information that camera module 100 is more detailed.As: factory setting, the details such as each work station tuning parameter historical record, so that follow-up analysis tracking work.The identity coding sign 110 of laser-induced thermal etching on stiffening plate is not easy to come off equally, can be retained on stiffening plate always, and conveniently read.
Identity coding sign 110 forms an integral body with camera module 100, and the etching ground particularly identity coding sign 110 of laser-induced thermal etching is not easy to come off, and can be retained on camera module 100 always, and save label paper of the prior art.
For convenience of the installation of camera module 100, camera module 100 also comprises the connector 160 being welded on circuit board 110.Preferably, circuit board 110 is flexible PCB.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
