Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 , figure 2 and image 3 As shown, a fixed-focus module includes a lens base assembly A, a lens barrel assembly B, and an image sensor assembly D. The image sensor 2 in the image sensor assembly D is attached to the upper surface of the circuit board 1, and the lens barrel assembly B is fixed On the mirror base assembly A, it also includes a fine-tuning assembly C, which is located between the mirror base assembly A and the lens barrel assembly B. The fine-tuning assembly C is a fine-tuning adjustment ring, and the rotating fine-tuning adjustment ring is used to adjust the The distance between the first lens 9 inside and the second lens 5 installed in the mirror base assembly A is easy to adjust the focus by rotating the fine-tuning adjustment ring, which saves assembly time, effectively improves production capacity, and is conducive to mass p...

Abstract

The invention discloses a focusing module and an assembly process thereof. The focusing module comprises a lens base component, a lens cone component, an image sensor component and a fine-tuning component, wherein an image sensor in the image sensor component is clung to the upper surface of a circuit board, the lens cone component is fixed on the lens base component, the fine-tuning component is located between the lens base component and the lens cone component, the lens base component is mounted on the image sensor component, and the lens cone component comprises a lens cone internally provided with a first lens. According to the invention, the lens base is directly mounted on the image sensor, requirements on the flatness and centrality of the circuit board are lowered, and meanwhile, owing to the added fine-tuning component, the focusing is convenient, the assembly time is saved, the production capacity is effectively improved, and mass production is facilitated.

Description

technical field [0001] The invention belongs to the technical field of camera modules, and in particular relates to a fixed-focus module and an assembly process thereof. Background technique [0002] The fixed-focus module in the existing camera module is mainly composed of lens, lens holder, image sensor and circuit board. The assembly process of the fixed-focus module is as follows: First, the image sensor is attached to the Then position the lens base on the circuit board, the lens and the lens base are connected through threads, and the focus of the lens falls on the image sensor through manual focusing, and then the image can be clearly imaged; finally, glue is fixed on the thread of the lens . [0003] Since the reference plane of the assembly process is the surface of the circuit board, there are high requirements for the flatness of the circuit board, the symmetry of the positioning hole center on the circuit board, and the SMT positioning center. If the torque of ...
