Specific embodiment
With reference to the accompanying drawings and examples, to the structurally and functionally former of the test macro of the camera module of the utility model
Reason is described further:
Embodiment one
As shown in Fig. 1 ~ Fig. 2, the utility model specific embodiment provides a kind of survey of the camera module 10 of band LED12
Test system.Camera module 10 is including camera 11, the sensitive chip (not shown) positioned at 11 bottom of camera, and
LED12, camera 11 and LED12 are all located on the bracket 13 of camera module 10.Test macro includes test fixture 50, test
Jig 50 is electrically connected with camera module 10.The test macro further includes providing confined air simultaneously for camera 11 and LED12
Between sealing chamber 20, also there is in the sealing chamber 20 reflex reflector all corresponding with the position of the camera 11 and LED12
30。
The test macro of the utility model cleverly utilizes the self-contained camera 11 of camera module 10 and photosensitive
Chip makes reflex reflector 30 that the LED12 light issued is reflected into camera by the way that reflex reflector 30 is arranged in sealing chamber 20
11, the sensitive chip of 11 bottom of camera can convert electric signal, final test for optical signal received by camera 11
Whether just smelting tool collects the electric signal, and the LED12 function of camera module 10 can be judged according to the data of electric signal
Often.Requirement of the test macro of the utility model to test equipment is lower, and operating method is easy, improves testing efficiency.
One of embodiment as LED12 and 11 relative position of camera: as shown in Figure 1, LED12 and camera
11 are respectively facing different directions, such as the camera module 10 of computer peripheral accessory, can be with other than being imaged
When light is bad, illumination is provided.
Another embodiment as LED12 and 11 relative position of camera: as shown in Fig. 2, LED12 can be with camera shooting
First 11 settings in the same direction, such as common mobile phone camera module 10.
Reflex reflector 30 receives LED12 light, and the light received is reflected to camera 11 again.Reflex reflector 30 can
To be reflective mirror or reflector, it is fixed on inside sealing chamber 20.The reflex reflector 30 is one or more.Such as Fig. 1 institute
Show, reflex reflector 30 is reflector, and quantity is 3, the light that 3 reflex reflectors 30 will be issued from LED12, by repeatedly anti-
It penetrates, injects with LED12 towards entirely different camera 11.As shown in Fig. 2, 30 quantity of reflex reflector is 2,2 reflective
The light that device 30 will be issued from LED12 is injected with LED12 after reflection towards identical camera 11.Certainly, reflex reflector
30 also can be set 1, and 1 reflex reflector 30 had both received the light of LED12, and light reflection is also given to camera 11 simultaneously.
In the present embodiment, the specific structure of sealing chamber 20 includes bottom plate 22 and cover 21, and bottom plate 22 is, for example, testboard.
Camera module 10 is placed on bottom plate 22, and cover 21 covers in camera module 10.Bottom plate 22 and cover 21 constitute one
Closed, lighttight enclosure space 40, extraneous light do not affect the test of camera module 10, in LED12 no power
In the case where, camera 11 does not receive light.
Test fixture 50 is dedicated test equipment.Preferably, the test fixture 50 also has display device and/or language
Sound suggestion device.Test fixture 50 is handled and is judged to the level signal received by built-in software program,
Judging result is fed back finally by the form of text and/or voice.
It is understood that test macro further includes the external power supply (not shown) powered for camera module 10.
Embodiment two
What is different from the first embodiment is that in the present embodiment, reflex reflector 30 is exactly the inner surface of sealing chamber 20, such as Fig. 3
It is shown, therefore do not need additionally to increase reflective mirror or reflector, accordingly, with respect to embodiment one, test macro is simpler.
More specifically, the inner surface of sealing chamber 20 can be arranged to the color of the higher light color of reflecting rate.Such as brilliant white or white
Color.The inner surface of white inherently has preferable reflecting effect.Further, in order to make the inner surface for reflecting of sealing chamber 20
Effect is more preferable, can be handled with inner surface, and the inner surface of sealing chamber 20 is made to have reflection light coating.Reflecting light coating can
So that the reflection that is more smooth, being more favorable for light of inner surface.
In the present embodiment, the inner surface for reflecting part of sealing chamber 20 is rectangular, is the inner wall of rectangular cover 21.
Embodiment three
Unlike embodiment two, as shown in figure 4, in the present embodiment, the inner surface for reflecting part of sealing chamber 20 is
Arc, be the inner wall of arc cover 21.Compared with embodiment two, the present embodiment can make for reflective arc inner wall
The diffusion of the light that LED12 is issued more evenly, effect are more preferable.More preferably scheme is the inner surface for reflecting portion of sealing chamber 20
It is spherical for dividing, and is spherical or semi-spherical shape cover 21 inner wall.
Example IV
Unlike above embodiments, as the alternative solution of 20 specific structure of sealing chamber, sealing chamber 20 includes having
Open container, and the lid positioned at opening.In test, after camera module 10 is put into container from opening, will open
Mouth is covered with lid.
Compared with prior art, the beneficial effects of the utility model are as follows:
The test macro of the utility model, the camera and photosensitive core for cleverly utilizing camera module self-contained
Piece makes reflex reflector that the LED light issued is reflected into camera, camera bottom by the way that reflex reflector is arranged in sealing chamber
Sensitive chip can convert optical signal received by institute's camera to electric signal, final test smelting has the collected electricity
Signal, and can judge whether the LED function of camera module is normal according to the data of electric signal.The test of the utility model
Requirement of the system to test equipment is lower, and operating method is easy, improves testing efficiency.
Finally, it should be noted that above embodiments are only to illustrate the technical solution of the utility model embodiment rather than right
It is limited, although the utility model embodiment is described in detail referring to preferred embodiment, this field it is common
Technical staff should understand that still be modified or replaced equivalently the technical solution of the utility model embodiment, and this
A little ranges modified or equivalent replacement cannot also make modified technical solution be detached from the utility model embodiment technical solution.
