Disclosed is a device for rapidly and comprehensively inspecting a lens actuator, the device comprising a bracket () for fixing the lens actuator, a cone-shaped body () and a camera (), wherein the outer surface of the cone-shaped body () is a mirror surface, the cone-shaped body () is mounted on the top of the bracket (), and the camera () is hung above the cone-shaped body (). Further disclosed is a system employing the above-mentioned device for rapidly and comprehensively inspecting a lens actuator, and a method for inspecting a lens actuator by using the above-mentioned device. A rapid inspection can be realized so as to facilitate quality inspection and control in mass production, and a comprehensive inspection also can be realized, the inspection items including lens stroke, magnitude of inclination and the similar items under different control conditions.

Device, system, and method for rapidly and comprehensively inspecting lens actuator

A structure for a voice coil motor providing controllable lens tilt capability. The voice coil motor structure comprises a lens mount for fixedly mounting a lens (), a focusing coil (), a tilting coil () and magnets (-), wherein the focusing coil () and the tilting coil () are respectively and fixedly sleeved on the outer side of the lens mount (). The magnets (-) are distributed around the focusing coil () and the tilting coil () to allow the focusing coil () to interact with the magnets (-), so that the focusing coil () drives the lens mount () to move front and back to realize lens focusing. The tilting coil () is interacted with the magnets (-) to allow the tilting coil () to drive the lens mount () to tilt and realize lens shift. By virtue of the structure, the focusing and controllable tilting angle of the lens can be realized at the same time. The three-coil structure enables the camera to keep small size and easy to be produced at large scale; impedances of coils are easy to be matched with conventional motor driving circuits; the structure can be widely applied to the current smart cell phones to provide a shooting function same to the medium-end or high-end digital camera.
