Lens linear actuator and assembly technology thereof

Abstract

The invention discloses a lens linear actuator and an assembly technology thereof. An actuator fixing support serves as a main body of an actuator. Four supporting rods extending upwards are respectively arranged on four corners of the fixing support for the actuator, and form an accommodating cavity. Lower plane springs are mounted on the lowest layer of the inner portion of the accommodating cavity, a lens support body is mounted above the lower plane springs, a focusing coil is sleeved on the outer side of the lens support body, and magnets are respectively arranged between the focusing coil and the supporting rods. A gasket provided with upper plane springs is arranged above the focusing coil. A shell is sleeved on the outer side of the fixing support of the actuator, and is fixedly connected with the fixing support of the actuator. By means of a special structure design, all relevant components are assembled in the same component, so that the corresponding position of each component and quality parameters of products can be effectively guaranteed; control of optical axis deflection angles is specially facilitated; and the lens linear actuator is simple in assembly with fewer components, and is easy in mass production.

Description

Technical field [0001] The invention discloses a lens linear driver and its assembly process, in particular to a lens linear driver with high reliability specially matched for the focusing of a miniature camera; the invention relates to a highly integrated, miniaturized, high-resolution sensor and Lens coordination is widely used in devices such as miniature cameras, mobile phones, computers, automobiles, and robots that have auto-focus functions. Background technique [0002] With the continuous advancement of technology, the emergence and development of smart phones, smart phones are increasingly used in people’s lives, and the camera or camera function has almost become a necessary function of smart phones. With 5M , 8M, 12M and other high-pixel cameras are becoming more and more popular, and the camera and camera functions of mobile phones are becoming more and more powerful, and the requirements for the lens driver as an important part of the camera are also getting ...

AI Technical Summary

Problems solved by technology

[0003] As mentioned above, the lens linear actuator in the prior art adopts an upper and a lower two-part structure, which are assembled separately and then installed together, which may easily cause the optical axis to be inconsistent with the optical axis of the lens, or increase the production cost. The invention provides a new lens linear driver and its assembly method. It adopts a special structural design, which can realize that all components are assembled on the same component, and adopts a unified reference, which can effectively ensure the relative position of each component, which is beneficial to Guarantee the quality parameters of the product
