Device and method for testing lens modules

A method for testing lens modules, the method comprising the steps of:

• providing a device for testing the lens modules, the device comprising a testing platform defining a receiving opening;
• an image sensor facing towards the receiving opening;
• a light source assembly disposed at a side of the testing platform opposite to the image sensor, the light source assembly being aligned with respect to the image sensor, the light source assembly being configured for providing predetermined testing specimens;
• and a turnplate received in the receiving opening, the turnplate defining at least two through holes configured for receiving lens modules to be tested;
• sequentially receiving the lens modules to be tested into the at least two through holes and rotating the turnplate to cause the at least two through holes receiving the lens modules therein to face towards the image sensor one by one;
• catching the image of the testing specimen formed by the lens modules in the through hole via the image sensor one by one;
• and
• determining the testing result based on the image caught by the image sensor.
