In recent years, with the popularization of mobile electronic devices, related technologies of camera modules (for acquiring images, such as videos or images) applied to the mobile electronic devices are rapidly developed and advanced, and the camera modules are widely applied to various fields, such as medical treatment, security, mobile terminals, industrial production and the like.
In the field of consumer electronics, particularly in the field of smart phones, a miniaturized and lightweight camera module is an indispensable component, and at least one or more camera modules are currently arranged on a mobile terminal body. The diaphragm of the current mobile phone camera module can be divided into variable and invariable two kinds, and no matter which scheme, the diaphragm device is an important part of the camera module, and as an indispensable element of an optical system, the diaphragm device is arranged on/in a lens when the lens is assembled in a structural part mode. The area of the aperture directly affects the light input amount of the camera module, and the brightness and the depth of field of the image are also affected. When the area of light ring is great, the module of making a video recording has the bigger light inlet amount for the image luminance that forms is high and the background blurring is effectual, and when the area of light ring is less, the light inlet amount of the module of making a video recording is also less, makes the image detail of formation more clear.

In the conventional lens assembly process, in order to ensure that a certain design parameter standard is achieved, each lens and the middle blocking piece in the lens are sequentially overlapped and assembled in at least one lens barrel. For the iris diaphragm device, if the size of the light through hole needs to be changed, an external structure needs to excite the change of the light through hole, so that the iris diaphragm device is placed on the lens, the total height of the camera module is lengthened, the camera module is not beneficial to being applied to terminal equipment such as a mobile phone and a flat panel with limited installation space, and the application of the camera module with the iris diaphragm device is limited.
