Abstract

The invention provides an imaging module and a manufacturing method thereof. A piezoelectric element supports and connects a moved element, a limit groove is provided on the surface of the moved element, and a fixed end of the piezoelectric element is fixed to a support block. The movable end extends into the limit slot, the limit slot provides a moving space for the movable end, and the limit device includes a base, a support block and a positioning block located on the base, the base, the support block and the positioning block to enclose a space, the piezoelectric element and the limit slot are located in the space, and the positioning block is located around the limit slot; the limit slot is arranged in the space of the limit device, and is limited by the limit device. Under the action of the piezoelectric element, the limiting groove can only move up and down, thereby solving the problem of lateral movement of the moved element.

Description

technical field [0001] The invention relates to the technical field of motion control, and in particular, to an imaging module and a manufacturing method thereof. Background technique [0002] In some electronic terminals, it is usually necessary to make some of the components translate, vertically move or tilt, so as to realize some special functions. For example, in various electronic terminals such as cameras, cameras and mobile phones with lens modules, the movable lens or image sensor is usually driven by a driving mechanism such as a VCM motor (Voice Coil Actuator / Voice Coil Motor, voice coil motor). , displaced in the optical axis direction to focus or zoom, or displaced in the direction perpendicular to the optical axis direction to prevent optical shake. However, unlike traditional SLR cameras, it is a huge engineering challenge to implement this function in electronic terminals such as mobile phones, miniature cameras, and cameras with small space and volume.
