Abstract

The invention provides an imaging module and a manufacturing method thereof, a piezoelectric element is supported and connected with a moved element, a limiting groove is arranged on the surface of the moved element, a fixed end of the piezoelectric element is fixed on a support block, a movable end of the piezoelectric element extends into the limiting groove, the limiting groove provides a moving space for the movable end, the limiting device comprises a base, and a supporting block and a positioning block which are located on the base, a space is defined by the base, the supporting block and the positioning block, the piezoelectric element and the limiting groove are located in the space, and the positioning block is located around the limiting groove; and the limiting groove is formed in the space of the limiting device, and the limiting groove can only move up and down under the action of the piezoelectric element under the limitation of the limiting device, so that the problem that the moved element moves transversely is solved.

Description

technical field [0001] The invention relates to the technical field of motion control, 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 parts thereof translate, move vertically or tilt, so as to realize some special functions. For example, in various electronic terminals such as video cameras, cameras, and mobile phones with lens modules, a driving mechanism such as a VCM motor (Voice Coil Actuator / Voice Coil Motor) is usually used to make the movable lens or image sensor , shift in the direction of the optical axis to focus or zoom, or shift in a direction perpendicular to the direction of the optical axis 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 spaces. Moreover, as the imaging sy...
