Abstract

The invention discloses a camera module active alignment device and an alignment method thereof. The camera module active alignment device comprises a lower base, a photosensitive element assembled with the lower base, an upper base, a lens assembled with the upper base, and a clamp for clamping the upper base. First fine adjustment tools of which extension directions are a vertical direction areset at four corners of the clamp and are used for finely adjusting the distance between the lens and the photosensitive element and carrying out optical axis alignment of a camera module. A second fine adjustment tool of which extension direction is a horizontal direction is set in the middle of the clamp and is used for finely adjusting central position offset between the lens and the photosensitive element and carrying out optical central alignment of the camera module. According to the device and the method, through setting of the first fine adjustment tool and the second fine adjustment tool, the angle and optical central position offset between the lens and the photosensitive element in the camera module can be adjusted, thereby finishing aligning, the operation is simple and the accuracy is high.

Description

technical field [0001] The invention relates to the field of camera technology, in particular to a camera module active calibration device and a calibration method thereof. Background technique [0002] Due to the increasing demand for threadless lenses and the increasing popularity of the Active Alignment (AA) process, the use of machine AA not only requires high costs to make related fixtures, but is also limited by the lens angle of view and light source panel, some camera modules Machine AA can't be done yet. The equipment and method of manual AA will become an inevitable trend in the early stage of the project. [0003] Therefore, how to make the manual AA operation simple and highly accurate is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the object of the present invention is to provide an active camera module calibration device and its calibration method, which can adjust the angle betw...
