Split type periscope module, and assembly method and application thereof

Abstract

The invention discloses a split type periscope module, and an assembly method and an application thereof. The split type periscope module comprises a light turning component and a module component, wherein the module component comprises a lens and a photosensitive component, and the lens is positioned in a photosensitive path of the photosensitive component; the light running component is assembled into the module component in a split and modularized manner, the lens is positioned in a light ray exiting direction of the light turning component, and thus a light ray turned by the light turning component and exiting from the same reaches the lens.

Description

technical field [0001] The present invention relates to the field of camera modules, and further relates to a split type periscope module and its assembly method and application. Background technique [0002] In recent years, with the rapid development of smart phones, the demand for mobile phone camera modules is increasing day by day, and the competition for mobile phone camera modules has also become increasingly fierce, especially for the design of dual cameras. Not only is it required that the dual cameras can achieve background blur and clear night shots, but also that the dual cameras can achieve optical zoom without increasing the height of the module, so a periscope dual camera module has been produced. [0003] A periscope dual camera module is usually a combination of a periscope camera module and a traditional module. The periscope camera module reflects the vertically incident light at the end of the module by adding a prism to the front of the traditional modu...

[0008] Third, if the AA (Active Arrangement, automatic calibration) process is used for assembly, there is no AA adjustment space between the prism and the integrated bracket, even after the AA process is completed, the glue cannot be painted

[0009] Fourth, during the assembly process of the prism and the lens, both parts are exposed to the air for a long time, and there is a very high risk of dust entering the module during the assembly process and causing bad stains

[0010] In addition, in the traditional integrated assembly structure, the prism is fixedly installed on the assembly bracket, and the relative angle between the prism and the lens is not easy to adjust, so the module is not easy to achieve optical image stabilization

[0011] To sum up, the assembly accuracy of the periscope module with traditional structure and its assembly method depends on the accuracy of the bracket, the assembly is difficult, there is no scientific assembly method, and the assembly speed is slow, which greatly affects the imaging effect of the module and the feasibility of module assembly The post-production quality of the module has caused great hidden dangers, so it is necessary to design the periscope module and its assembly method, which can not only meet the original functions of the periscope module, but also reduce or avoid the Exposure to the air for a long time will cause a large number of particles to enter the interior of the module, resulting in poor stains, and avoid the above-mentioned various adverse factors caused by it
