Abstract
The utility model discloses a kind of proving installation for micro-sound coil motor, comprise a laser generator, be evenly located at least 3 position detecting devices of micro-sound coil motor surrounding oblique upper, described laser generator transmitting at least 3 bundle laser, aim at evenly and at intervals the check point of the rotor of micro-sound coil motor, described position detecting device receives the laser signal after the diffuse reflection of rotor check point, when rotor motion, position detecting device is according to the laser signal changing, the displacement of output detections point.The utility model detection efficiency is high, precision is high, to micro-sound coil motor not damaged, for the detection of micro-sound coil motor provides new simpler detection mode.
Description
Technical field
The utility model relates to the proving installation of micro-sound coil motor, relates in particular to the testing apparatus that can detect autofocus motor and the anti-shake motor of optics.
Background technology
Micro-sound coil motor is widely used in the portable electric appts such as smart mobile phone, panel computer, development along with voice coil motor, its kind is more and more, function is also more and more abundanter, in order to ensure it, after coming into operation, can stablize constantly normal work, its property must be through well detecting and checking.
Current motor checkout equipment on the market all need to be installed a false camera lens on micro-sound coil motor, and so false camera lens must fix with voice coil motor, causes on voice coil motor and damages for the thread of true camera lens is installed, and causes motor failure.And the mode that adopts false camera lens to detect micro-sound coil motor, its detection time is longer, efficiency is very low, the complex structure of pick-up unit, if in testing process, precision and the position of false camera lens are uncertain, will cause the inaccurate of detection, produce erroneous judgement, motor can not be met the need of market completely.
Therefore, how providing a kind of checkout equipment that can be used for precision measurement micro-sound coil motor (the anti-shake motor of autofocus motor and optics) performance parameter is industry technical matters urgently to be resolved hurrily.
Summary of the invention
The utility model is in order to solve the technical matters existing in above-mentioned prior art, a kind of proving installation for micro-sound coil motor is proposed, comprise a laser generator, be evenly located at least 3 position detecting devices of micro-sound coil motor surrounding oblique upper, described laser generator transmitting at least 3 bundle laser, aim at evenly and at intervals the check point of the rotor of micro-sound coil motor, described position detecting device receives the laser signal after the diffuse reflection of rotor check point, when rotor motion, position detecting device is according to the laser signal changing, the displacement of output detections point.
In one embodiment, described position detecting device is PSD position transducer.
In another embodiment, described position detecting device is camera.
The utility model adopts laser generator and position detecting device to detect the displacement of micro-sound coil motor and deflection, do not need to be fixed and to be connected with miniature voice coil loudspeaker voice coil, can not damage accurate micro-sound coil motor hardware, and compare with false camera lens, accuracy of detection is higher, detection time is short, has greatly simplified the detection operation of micro-sound coil motor.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model;
Fig. 2 is the vertical view of micro-sound coil motor of the present utility model.
Embodiment
Below in conjunction with meeting detailed description specific embodiment of the utility model; following specific embodiment is only in order to illustrate design of the present utility model; those of ordinary skill in the art can make various deformation and variation under design of the present utility model, and these distortion and variation include within protection domain of the present utility model.
As shown in Figure 1, the proving installation for micro-sound coil motor that the utility model proposes mainly comprises two kinds of parts: laser generator 1 and position detecting device 2, laser generator 1 is arranged on the top of micro-sound coil motor 3, 2 oblique uppers of being located at micro-sound coil motor 3 surroundings of position detecting device, be circulating type, position detecting device 2 is at least provided with 3, laser generator 1 can transmitting at least 3 be restrainted laser, aim at evenly and at intervals the check point of the rotor 31 of micro-sound coil motor 3, then by position detecting device 2, receive the laser signal after the check point diffuse reflection of rotor 31, rotor 31 is when static, position detecting device 2 can detect the laser signal after check point diffuse reflection, when rotor 31 motion, laser signal can change, then position detecting device 2 is according to the laser signal changing, the displacement of output detections point, those skilled in the art can draw displacement and the deflection of voice coil motor motion according to the displacement of a plurality of check points.
In one embodiment, position detecting device 2 can adopt PSD position transducer, quantity can arrange more than 3, in the present embodiment, laser generator 1 has sent 4 bundle laser, aimed at respectively rotor 31 all directions to four check points, PSD position transducer is provided with 4, be respectively used to receive 4 laser signals, by detecting the variation of 4 laser signals, can draw the displacement of micro-sound coil motor 3, by detecting the variation of 2 laser signals on diagonal line, the deflection that can draw micro-sound coil motor 3.
In other embodiments, position detecting device 2 can also adopt shooting first-class, equally also belongs to protection domain of the present utility model.
In the present embodiment, available laser generator model can select that 5mW, 650nm are general, a kind of in Melles Griot/05-LHP-151, and the model of PSD position transducer can be selected a kind of in DRX-2DPSD-14AMD, DRX-2DPSD-JT01, DRX-1DPSD-A01.The utility model, by adopting laser generator 1 and corresponding position detecting device 2, can accurately draw the moving situation of micro-sound coil motor 3, and compared with prior art, structure is simpler, and testing result is more accurate.
