Embodiment Construction
[0085] The following description serves to disclose the present invention to enable those skilled in the art to carry out the present invention. The preferred embodiments described below are only examples, and those skilled in the art can devise other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present invention.
[0086] In a traditional focusable camera module, the lens module usually includes a lens and a focusing mechanism, wherein the lens includes an optical lens and a lens barrel for carrying the lens, and the focusing mechanism includes a carrier (Holder), which is connected to other parts of the focusing mechanism , and the carrier is used as a moving part carrier, which has threads inside and cooperates with the lens through threads or other methods, that ...

The invention discloses an adjustable optical lens integrated with a focusing mechanism, a camera module and a manufacturing method thereof, wherein the adjustable optical lens includes at least one optical lens, a focusing mechanism and a carrying structure, and each optical lens is along the The height direction of the load-bearing structure is installed in the internal space of the load-bearing structure, wherein at least one of the optical lenses is used as an adjustable lens, and the assembly position of the adjustable lens in the load-bearing structure is adjusted , which is beneficial to ensure the imaging quality of the camera module. The carrying structure is further connected to the inside of the focusing mechanism as the carrier of the focusing mechanism, and moves with the power of the focusing mechanism, and is suitable for focusing. The carrying structure is used as the carrier of the lens barrel and the focusing mechanism, so that the assembly tolerance chain is shortened, the assembly process is reduced, and it is beneficial to improve production efficiency and product yield.
Description
technical field [0001] The invention relates to the field of camera modules, in particular to an adjustable optical lens integrated with a focusing mechanism, a camera module and an assembly method thereof. Background technique [0002] With the increasingly fierce competition in the camera module market, the reduction of camera module manufacturing costs, the improvement of production efficiency and the improvement of image quality have become the goals that camera module manufacturers are constantly chasing. [0003] Usually, an adjustable-focus camera module is composed of important components such as a lens, a focusing mechanism, and a photosensitive chip. The manufacture of an adjustable-focus camera module is usually an assembly of these components. Assembling the parts, after the assembly is completed, assemble the finished lens and the focusing mechanism, and then complete the assembly of the camera module. This method has the following problems: first, the assembly...
