Anti-shake system for micro camera

Abstract

The present invention provides a kind of anti-shock system for micro-camera, which is mainly provided with a flexible circuit board on the four sides and the top inside, including two pairs (four) of anti-shock coils and a focus coil; A bracket with three corner seats is attached to the inner edge of the flexible circuit board; four anti-vibration coils are arranged between the four corner seats of the bracket, and the two pairs are arranged in series to form the static part of the anti-shock system; A camera objective lens seat is provided with a magnetically conductive yoke iron, and four magnets are respectively arranged on the periphery of the objective lens seat, and are arranged at intervals with the aforementioned four anti-vibration coils to form the mover part of the anti-shock system; An upper shrapnel and a lower shrapnel are respectively connected with the above-mentioned stator part and mover part to form an anti-shock system capable of moving independently in the X-Y-Z axis.

Description

Anti-shake system for miniature cameras technical field The present invention relates to a kind of anti-handshake system of miniature camera, especially about a kind of three-dimensional three-axis magnetic circuit that can be done The system's anti-shake focusing motor device can be widely used in mini photography equipment or matching with mobile phone camera systems. It has the advantages of saving parts and assembly costs, and not occupying a volume. Background technique [0002] The technology of the motor of the miniature camera module is also more important as the photographic device tends to be lighter, thinner and shorter. Especially when the mobile phone has become an indispensable item in life, the need for the micro motor matched with the mobile phone is even more fulfilled. The peak, so the requirements for the anti-shake technology of micro motors are constantly increasing. [0003] For the optical anti-shake (Optical Image Stabilization, hereinafter refe...

Problems solved by technology

[0006] Tilt lens (Lens tilt): the image sensor is fixed to the bottom of the camera housing, and the lens is tilted; but this method can only compensate for small amplitude vibrations (the actual test can only reach a range of less than 0.5 degrees), and the lens Tilting with the image sensor will also cause blurred images at the four corners of the camera, which is its main disadvantage

[0007] Tilting the entire camera (CCM Tilt): mainly to solve the problem of image blur in the four corners above, especially the image sensor and the lens need to be integrated in the same body, and two movement angles are compensated; but this disadvantage is that the size cannot be small At the same time, the rigidity of the image cable seriously affects the pass rate and its main disadvantage

[0008] Lens Shift: The image sensor is fixed to the bottom of the camera housing, and the lens performs a translational movement; although this method is currently the only way to achieve miniaturization while taking into account the image quality, such as US7,881,598 B1 translational OIS, but the number of parts is too many, and the assembly requires complicated procedures, resulting in high cost, which is its main disadvantage
