Camera lens module locking method

Abstract

The embodiment of the invention discloses a camera lens module locking method. The camera lens module locking method is applied to a camera lens module locking device. A camera lens module comprises acamera lens and a base; the camera lens module locking device comprises a power unit, a control unit and a torsion detection unit; the control unit is correspondingly connected with the power unit and the torsion detection unit. The camera lens module locking method comprises the steps that the power unit is controlled to drive the camera lens to move towards the base to reach the preset height according to a locking starting instruction; in the process of the camera lens moving towards the base, the camera lens is occluded with the base to form the camera lens module; the actual height and the theoretical height of the camera lens module are obtained, and correction parameters of the power unit are determined according to the actual height and the theoretical height; and the power unit is corrected according to the correction parameters, and the locking of the camera lens module is completed. According to the technical scheme of the camera lens module locking method, errors exist inthe locking process of the camera lens module are corrected, and the locking precision is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of lens module locking, in particular to a lens module locking method. Background technique [0002] In recent years, with the development of multimedia technology, the scope of application of lens modules has become wider and wider, and has been widely used in digital cameras, video cameras, and mobile phones with camera functions. Portable electronic products. The lens module generally includes a lens and a base that matches the lens, and the lens includes a lens barrel and a plurality of optical elements arranged in the lens barrel, such as lenses and filters. The lens barrel and the base are provided with matching threads, through which the lens can be controlled to screw in on the base to adjust the focal length. [0003] For a fixed-focus lens module of a certain model, the screw-in depth of the lens and the base is determined. During the locking process of the lens and the base, the lens ...
