Technical field

The invention relates to the field of camera modules, and further relates to a split array camera module and a manufacturing method thereof.

Background technique

With the continuous development of smart devices, the requirements for camera modules are getting higher and higher. For example, in the past two years, the camera of a smart phone has changed from a single camera to a dual camera, and the development of the dual camera module has become an important trend in the development of mobile phone camera modules.

Simply put, the dual camera can capture images with the cooperation of two cameras, enabling a richer image acquisition function. The existing dual cameras can be divided into two categories according to their functions: one is to use three cameras to generate stereo vision, to obtain the depth of field of the image, to use the depth of field information for background blur, 3D scanning, auxiliary focus, motion recognition, etc., or to utilize The information of the two pictures is fused; the other type is to use two different pictures on the left and right to achieve better resolution, better color, dynamic range and other better image quality or optical zoom function. .

On the other hand, the pixel requirements of the camera module are getting higher and higher, and the number of lenses of the lens is increasing. From the original two or three pieces to the current five, six or even more pieces, facing the high-pixel camera module. The requirement is that the volume is small, on the other hand, the problem of good optical imaging quality is required, and the module for multi-camera is also faced with such a problem, how to make the module as a whole suitable for high pixels, and stable or safe to two or The plurality of camera modules cooperate with each other to form an integral module to meet the requirements of the multi-camera module in the development of the existing camera module, which is a problem to be solved.

When the camera is installed in an electronic device, such as a smart phone, the external needs to be flat, and the appearance of the two cameras is beautiful. Therefore, how to assemble the external rules of the two camera modules is one of the problems to be considered in the multi-camera module.

Furthermore, the consistency of the optical axis between multiple cameras is an important aspect of the optical design of the multi-camera camera module. How to ensure that multiple camera modules can be assembled in one body and ensure the consistency of the optical axis. This is a multi-camera. A problem to be considered in the manufacture of camera modules.

Further, two mutually matched cameras respectively collect image information, and the accuracy of the image acquisition and the image quality are closely related to the incident light of the two cameras, and the optical axis consistency between the two cameras ensures the imaging quality of the camera module. Foundation. That is to say, how to improve the optical axis consistency of the two camera modules on the basis of stably and compactly fixing two cameras, or to make the error within a predetermined range, thereby improving the precision of the installation and making it more accurate Good image quality is another important issue to consider for the development of dual cameras.

Further, the conventional camera module is usually a camera module assembled by a COB method, and the basic structure thereof comprises a circuit board, a photosensitive element, a lens holder, a lens and a filter element, wherein the photosensitive element is attached The circuit board is electrically connected to the circuit board by a gold wire, the lens holder is mounted on the circuit board by glue, the lens is mounted on the lens holder, the filter element is mounted on the lens holder, and the circuit The board is usually provided with protruding electronic components. In this configuration, on the one hand, the lens holder is usually bonded to the circuit board after being manufactured by injection molding, and the mounting condition of the lens is not provided with good flatness, and the bonding fixing method increases the cumulative tolerance. On the other hand, the electronic component protrudes from the circuit board, so the installation space needs to be reserved when the mirror mount is installed, so that the overall required area of the circuit board is large, and the electronic component is exposed to the space inside the camera module, and the surface is contaminated with dust. Impurities can easily affect the imaging effect of the camera module. In short, the traditional COB placement camera module has many unfavorable factors, especially not suitable for the existing high-pixel camera module.

Further, the first camera module unit 10 and the second camera module unit 20 are respectively fixed to the side wall of the main body 31 of the assembly 30, for example, by glue bonding, thereby passing through The main body 31 provides a fixed position for the first camera module unit 10 and the second camera module unit 20, so that the first camera module unit 10 and the second camera module unit 20 are opposite. The position is determined to form an array structure. It is worth mentioning that the array described in the present invention is used to describe that each camera module unit forms a positional layout relationship, and is not limited to being arranged in a column manner, and the layout mode can be based on requirements and array camera modules. The number and type are determined, such as linear arrangement, triangular arrangement, symmetric arrangement, and the like.

More specifically, in some embodiments, the assembly body 30 may be a square frame structure, so that each of the camera module units is constrained and assembled in a square structured structure to facilitate installation applications, such as mounting on electronics. device. Of course, in other embodiments of the present invention, the structure of the assembly 30 may be deformed according to the size and structure of each camera module unit, thereby forming a regular or irregular structure, so that each of the camera modules The unit can be assembled stably.

Further, the assembly 30 includes an upper cover 33 adapted to block the main body 31 to facilitate closing the receiving chamber 32. Further, the upper cover 33 has at least two lens ports 331 corresponding to the camera module units, so that each of the camera module units performs daylighting through the lens port 331.

In this embodiment of the invention, the upper cover 33 is integrally connected to the main body 31, thereby constructing an integral receiving structure. For example, in the process of assembling the split array camera module,
