Camera module group combined method and camera module group

Abstract

The invention provides a combination method of a camera module and the camera module obtained by the method. The combination method of the camera module is used for combining a lens unit and a photographic unit and comprises the steps as follows: whether the locking adhesion surface of the lens unit is vertical to an optical axis thereof or not is detected; if not vertical, the locking adhesion surface is corrected till the locking adhesion surface is vertical to the optical axis; whether the assembly surface of the photographic unit is parallel to a photosurface or not is detected; if not parallel, the assembly surface is corrected till the assembly surface is parallel to the photosurface; and the assembly surface which is vertical to the optical axis is locked and adhered to the locking adhesion surface which is parallel to the photosurface. The combination method of the camera module respectively detects and corrects the lens unit and the photographic unit and further combines the lens unit and the photographic unit after the correction, thereby avoiding the possible splitting action from damaging elements after the combination. In addition, the combination method can avoid the repeated demolition and rotation operations and enhance the combination efficiency. The lens unit and the photographic unit which are obtained by utilizing the combination method of the camera module have great universality.

Description

technical field [0001] The invention relates to camera technology, in particular to a method for combining camera modules and a camera module. Background technique [0002] The camera module includes a lens unit and a photosensitive unit. The lens unit has an optical axis and a locking surface, the photosensitive unit has a photosensitive surface and an assembly surface, and the assembly surface is locked to the locking surface. When the camera module is assembled, the components are first assembled into a lens unit and a photosensitive unit, and then the lens unit and the photosensitive unit are combined into a camera module. [0003] In order to ensure the image quality, the camera module needs to meet the condition: the optical axis of the lens unit is perpendicular to the photosensitive surface (hereinafter referred to as the coaxial condition). However, limited by the component production process and assembly process, the directly combined camera module may not meet t...
