Description
Technical field
The present invention relates to mobile phone camera module group technical field, be specifically related to a kind of VCM motor float high test device and
Test method.
Background technology
VCM (Voil Coil Motor) motor, also known as voice coil motor is originally intended to loud speaker and generates vibration sounding, current
In the imaging modules for pushing camera lens movement to generate auto-focusing.VCM motor is the important component in camera module, it is not
It only determines auto-focusing (AF) ability of camera module, while being also to judge the key that a camera module is had excellent performance
Component.It is thus typically necessary to test in advance the performance of VCM motor, product volume production mistake is flowed into exclude the mono- product of bad VCM
Cheng Zhong, it is ensured that the product quality of camera module, still, currently, the performance test to VCM motor is only limitted to VCM motor
Starting current and the linear characteristic that falls after rise carry out test evaluation, lack and float high test evaluation to VCM motor.VCM motor floats height
If be bonded between referring to the barrel and pedestal of VCM motor bad, it will influence relative altitude between camera lens and barrel and
It tilts, leads to not meet camera lens and the fixed of barrel requires.
Invention content
In order to solve the above-mentioned technical problem, the present invention proposes that a kind of VCM motor floats high test device and test method, can be with
Verify that motor is floating high bad, you can verify that the barrel of VCM motor is bonded bad product with pedestal；And it is simple in structure,
It is easy to operate.
The technical proposal of the invention is realized in this way：
A kind of VCM motor floats high test device, includes for the measurement jig of stationary positioned VCM motor, for VCM horses
Up to DC power control case, the stroke for acquiring the camera lens installed on VCM motor barrel and the inclination that reverse current is added
The radium-shine rangefinder of data, the data for being acquired to radium-shine rangefinder carry out the controller of processing analysis and are used for display control
The display of result after device processing analysis.
Further, the measurement jig include pedestal, the test board that is fixedly arranged on the pedestal and can the relatively described bottom
The returning face plate that seat overturns and is fastened on the test board, the VCM motor are positioned on the returning face plate.
A kind of VCM motor floats high test method, and first, the VCM motor with camera lens is fixed positioned on measurement jig；
Then, by DC power control case, reverse current is added into the coil of VCM motor；Subsequently, it is adopted by radium-shine rangefinder
Collect the stroke and tilt data of camera lens on VCM motor；Then, the camera lens stroke that radium-shine rangefinder is acquired by controller and incline
Oblique data carry out processing analysis, finally, are showed the result after controller processing analysis by display；If VCM horses
Reverse current is destroked and tilt variation up to being added, then judges VCM motor qualification；If reverse current, which is added, in VCM motor has
Stroke and tilt variation then judge that the VCM motor is floating high bad.
The beneficial effects of the invention are as follows：The present invention provides a kind of VCM motor and floats high test device and test method, pass through by
VCM motor is fixed positioned on measurement jig, and reverse current is added into the coil of VCM motor by DC power control case；
The stroke and tilt data of camera lens on VCM motor are acquired by radium-shine rangefinder again；May determine that the barrel of VCM motor with
Whether it is bonded between pedestal closely, VCM negative testings can verify that motor is floating high bad.Its principle is as follows：Normal VCM motor
Barrel and pedestal between fit closely, reverse current is added, camera lens do not have stroke and inclined variation；If VCM horses
There are stroke and tilt variation up to reverse current is added, then judges that the VCM motor is floating high bad.The floating high test of VCM motor of the present invention
Apparatus structure is simple, easy to operate.
Description of the drawings
Fig. 1 is that VCM motor of the present invention floats high test device structural schematic diagram；
Fig. 2 is VCM motor negative testing wiring schematic diagram in the present invention；
In conjunction with attached drawing, make the following instructions：
1 --- measurement jig 2 --- VCM motor
21 --- barrel 22 --- pedestals
3 --- DC power control case 4 --- radium-shine rangefinders
5 --- display
Specific implementation mode
In order to be more clearly understood that the technology contents of the present invention, spy are lifted following embodiment and are described in detail, purpose is only
It is to be best understood from the protection domain that present disclosure is not intended to limit the present invention.
As depicted in figs. 1 and 2, a kind of VCM motor floats high test device, includes the test for stationary positioned VCM motor
Jig 1, the DC power control case 3 for reverse current to be added to VCM motor 2 are installed for acquiring on VCM motor barrel
Camera lens stroke and the radium-shine rangefinder 4 of tilt data, the data for being acquired to radium-shine rangefinder carry out processing analysis
Controller and the display 5 that the result after analysis is handled for display controller.In this way, by DC power control case to VCM
Reverse current is added in the coil of motor；The stroke and tilt data of camera lens on VCM motor are acquired by radium-shine rangefinder again；It can
Whether close to judge to be bonded between the barrel 21 of VCM motor and pedestal 22, VCM negative testings can verify that motor is floating
It is high bad.Its principle is as follows：It is fitted closely between the barrel and pedestal of normal VCM motor, reverse current is added, camera lens will not
There are stroke and inclined variation；If reverse current, which is added, in VCM motor stroke and tilt variation, judge that the VCM motor is floating
It is high bad.It is simple in structure that VCM motor of the present invention floats high test device, easy to operate.
Preferably, the measurement jig include pedestal, the test board that is fixedly arranged on the pedestal and can the relatively described pedestal
The returning face plate for overturning and being fastened on the test board, the VCM motor are positioned on the returning face plate.
A kind of VCM motor floats high test method, and first, the VCM motor with camera lens is fixed positioned on measurement jig；
Then, by DC power control case, reverse current is added into the coil of VCM motor；Subsequently, it is adopted by radium-shine rangefinder
Collect the stroke and tilt data of camera lens on VCM motor；Then, the camera lens stroke that radium-shine rangefinder is acquired by controller and incline
Oblique data carry out processing analysis, finally, are showed the result after controller processing analysis by display；If VCM horses
Reverse current is destroked and tilt variation up to being added, then judges VCM motor qualification；If reverse current, which is added, in VCM motor has
Stroke and tilt variation then judge that the VCM motor is floating high bad.
Above example is with reference to attached drawing, to a preferred embodiment of the present invention will be described in detail.Those skilled in the art
