The invention provides an optical lens assembling method. The optical lens assembling method comprises the following steps: 1) preparing a first lens component comprising at least one first lens and asecond lens component comprising at least one second lens; 2) shooting the first lens part; 3) adjusting the posture of the first lens part in posture adjustment freedom degree according to the distance measurement result, so that the included angle between the end surfaces of the first and second lens parts is smaller than an inclination angle threshold; 4) adjusting the first lens component onthe degree of freedom of linear movement to complete pre-positioning; 5) performing active calibration on the position of the first lens part on the linear movement freedom degree according to the actual imaging result; and (6) fixing the first lens part and the second lens part together to enable the relative positions of the first lens part and the second lens part to be kept at the relative positions determined by active calibration. The invention further provides a corresponding optical lens, a camera module and an assembling method of the camera module, and the comprehensive production efficiency of the optical lens or the camera module based on the active calibration technology can be improved.
Description
technical field [0001] The present invention relates to the technical field of photography and camera equipment, in particular, the present invention relates to the technical field of compact camera modules. Background technique [0002] Today, with the development of science and technology, consumers have more and more diverse needs for imaging, resulting in high-quality lenses such as large aperture lenses, telephoto lenses, and wide-angle lenses. Consumers have higher and higher requirements for imaging quality. In order to reduce the assembly difficulty of the lens and reduce the assembly tolerance of the lens and the camera module, the applicant proposed a method of dividing a complete lens into at least two lens components, and based on the imaging results, actively calibrate the at least two lens components, and then The relative position between each lens component is fixed, and the assembly method of assembling a complete lens, through active calibration, reduces th...
