Structure of single-lens with mechanic zero tile angle and adjustment method thereof

Abstract

A single-lens mechanic zero tilt angle adjustment method is disclosed, comprising a preparation step, an adjustment step and an engagement step, wherein preparation step comprising: disposing a lens at a voice coil motor (VCM), with a gap between the bottom of VCM and an engagement surface of an adaptor and the lens optical axis forming a tilt angle with the normal the adaptor plane; adjustment step comprising: adjusting the tilt angle by moving VCM and / or adaptor to zero degree and the optical axis perpendicular to the adaptor plane; and engagement step comprising: adhering the bottom of VCM to an engagement surface of adaptor to obtain a structure of single-lens mechanic zero tilt angle. As such, the adaptor plane is engaged to the image sensor, and the tilt angles between the lens optical axis o and the axis of the image sensor is zero to improve imaging quality.

Description

technical field [0001] The invention relates to a single-lens structure and an adjustment method thereof, in particular to a single-lens mechanical zero-tilt angle structure with an inclination angle of 0° between the optical axis of the lens and the axis of an image sensor and an adjustment method thereof. Background technique [0002] With the popularity of mobile phone camera functions, consumers have higher and higher requirements for the imaging quality of mobile phone photography. The improvement of imaging quality depends on the advancement of front-end design and manufacturing process. Among them, the relative angular offset (ie inclination) between the optical axis of the lens and the axis of the image sensor becomes one of the key factors affecting the image quality. [0003] like figure 1 and figure 2 shown, figure 1 It is a perspective view of a voice coil motor with a conventional single-lens structure, figure 2 is an exploded view of the existing single-...
