Assembly method and device of camera module, camera module and electronic equipment

Abstract

The invention provides an assembling method and device of a camera module, the camera module and electronic equipment. The assembly method of the camera module comprises the following steps: detecting the imaging quality of a lens on a photosensitive sensor when the lens is at a plurality of different rotation angle positions relative to the photosensitive sensor; and the lens and the photosensitive sensor are relatively fixed in the rotation direction by taking the rotation angle position when the imaging quality is qualified as a fixed position. According to the assembling method and the assembling device, the imaging quality after module assembling can be improved, and the reject ratio in module assembling production is reduced. According to the camera module provided by the invention, in the assembly process, the assembly position of the lens relative to the photosensitive sensor can be adjusted to the optimal position, the imaging quality after module assembly is improved, and the reject ratio of module assembly is reduced. The electronic equipment provided by the invention comprises the camera module.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and in particular to a method for assembling a camera module, an assembly device for a camera module, a camera module and electronic equipment. Background technique [0002] The batch manufacturing pass rate of mobile phone camera lenses and the camera clarity after assembly of camera modules have always been the focus of research and development by various mobile phone terminal and camera manufacturers. The imaging surface of the existing camera lens is circular, and the photosensitive sensor is mostly a 4:3 rectangle. Usually, the circular imaging surface of the camera lens needs to fully cover the photosensitive surface of the photosensitive sensor to prevent vignetting at the edge of the image; in addition, the camera lens is large. Part of the edge imaging surface is not accepted by the photosensitive sensor. For the same camera lens, the definition difference of diff...

AI Technical Summary

Problems solved by technology

For the same camera lens, the definition difference of different edge positions will be different. When the module is assembled, it cannot be guaranteed that the edge position with better definition can be effectively projected on the photosensitive surface of the photosensitive sensor during the test, that is, It cannot be avoided that the edge position with insufficient definition is projected onto the photosensitive surface of the photosensitive sensor

Therefore, in actual operation, it often happens that the lens is qualified in the sharpness test, but after being assembled into a module, the lens is scrapped due to insufficient edge sharpness.
