Photographing module with multiple camera lenses focusing respectively

Abstract

A photographing module with multiple camera lenses focusing respectively comprises a shell, elastic pieces, at least two lens seats, a plurality of magnetic stones or magnets, a plurality of coils and a plurality of leads. Each lens seat is provided with a lens assembling hole, and each elastic piece is positioned between the inner side of the shell and the corresponding lens seat in an abutted manner. Four coils are fixedly arranged on the outer sides of the four horizontal directions of each lens seat respectively, the magnetic stones or the magnets are fixedly arranged in the shell, and one magnetic stone or magnet is arranged on the outer side of each coil correspondingly. When being electrified, the coils generate magnetism mutually repelling with that of the magnetic stones or magnets. The leads are electrically connected with the coils to enable the coils to be electrified and generate magnetism. The photographing module with the multiple camera lenses focusing respectively has the advantages that except for a traditional focusing function in a Z-axis direction, each lens seat has a fine adjustment function in two angles of theta x and theta y, so that high-precision requirements on focusing during photographing is met, production efficiency and yield are increased because of structural simplification, and cost is lowered.

Description

technical field [0001] The invention relates to a photographic module, in particular to a photographic module with multiple lenses focusing separately. The photographic module can be assembled and applied to thin electronic products such as mobile phones, tablet computers, and smart watches. Background technique [0002] Multi-lens photography module (such as dual-lens) technology has been produced and applied by many mobile phone manufacturers. Compared with the traditional single-lens technology, dual-lens can improve the effect of photographic imaging or enrich the functions of photographic operations. It is accepted and loved by consumers and has become a trend in the industry. [0003] During the production and processing of multi-lens camera modules, the requirements for the parallelism of the optical axes of each lens are very high. Usually the relative tilt (tilt) of each lens is required < 10’ (VCM Actuator is required < 5’). Among them, there are many facto...

Problems solved by technology

Through the AA process technology, the 6 degrees of freedom of the lens (X, Y, Z, θ x, θ y and θ z) can be adjusted to adjust the relative position and inclination of each lens to ensure that the center of the picture is the clearest. And greatly improved the uniformity of the resolution of the four corners of the screen, so that the product consistency was improved, but it also caused the problems of high equipment cost and low yield and yield rate
