Abstract

The embodiment of the present invention discloses a lens module locking method, which is applied to a lens module locking device. The lens module includes a lens and a base; the lens module locking device includes a power unit, a control unit and a torque detection unit; the control unit is respectively connected with the power unit and the torque detection unit; the lens module locking method includes: controlling the power unit to drive the lens to the base according to the lock start command to a preset height; during the movement of the lens to the base, the lens engages with the base to form a lens module; obtains the actual height and theoretical height of the lens module, and according to the actual height and the The correction parameters of the power unit are determined theoretically; the power unit is corrected according to the correction parameters, and the lens module locking is completed. The technical solution of the embodiment of the present invention corrects the error existing in the locking process of the lens module and improves the locking accuracy.

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. A lens module generally includes a lens and a base matching the lens. 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 and the ba...
