Producer need to carry out the motor measuring mechanical property to the product with voice coil motor (Voice Coil Motor, VCM) after having assembled camera module.Conventional method of testing is finished by the test man is visual.Because the displacement of motor is less, the operator is difficult in the production run of short time, tells the relatively poor camera of those motor mechanical propertys, and testing efficiency is low, and False Rate is higher.
Summary of the invention
The embodiment of the invention provides a kind of camera module motor detecting instrument, and is low with testing efficiency in the solution prior art, the technical matters that False Rate is high.
A kind of camera module motor detecting instrument comprises:
Test platform is provided with the camera module screens, is used for carrying and fixing camera module;
Driver element, the motor that is used for the driving camera module moves to maximum position from initial position, returns initial position from maximum position again;
Laser head, the displacement that is used for measuring motor;
Processing unit is used for obtaining measurement data from driver element and laser head, and test data is carried out analyzing and processing.
The camera module tester that the embodiment of the invention provides adopts driver element to order about the motor motion, adopt laser head to measure the displacement of motor, and adopt processing unit to obtain measurement data, whole test process is finished by tester, improve testing efficiency, reduced False Rate.
Description of drawings
Fig. 1 is the structural representation of the camera module tester of the embodiment of the invention;
Fig. 2 is the motor curve movement synoptic diagram of the camera module tester output of the embodiment of the invention.
Embodiment
The embodiment of the invention provides a kind of camera module motor detecting instrument, and it is low to solve in the prior art testing efficiency, the technical matters that False Rate is high.Be elaborated below in conjunction with accompanying drawing.
Embodiment one,
Please refer to Fig. 1, the embodiment of the invention provides a kind of camera module motor detecting instrument.This camera module motor detecting instrument comprises: test platform 110, driver element 120, laser head 130 and processing unit.
