Voice coil motor carrier, voice coil motor, camera device, and lens mounting method

Abstract

The invention provides a voice coil motor carrier, a voice coil motor, a camera device and a lens mounting method. The voice coil motor carrier is used for bearing a lens, the voice coil motor carriercomprises a shell and a bearing body, the shell is provided with a first opening, the bearing body is arranged in the shell, the bearing body is provided with a second opening, the peripheral side ofthe second opening extends in the axis direction of the second opening to form a limiting part, the limiting part is provided with a boss, the lens sequentially penetrates through the second openingand the first opening, the peripheral side of the lens is clamped in the limiting part, and the lens further abuts against the boss. A gap between the lens and the boss is filled with an adhesive layer. The voice coil motor carrier, the voice coil motor, the camera device and the lens mounting method effectively solve the problem that the inclination of the lens is influenced by uneven shrinkage of glue after constant-temperature curing, and also have the advantages of tight connection and miniaturization of the bearing body and the lens.

Description

technical field [0001] The invention relates to the technical field of photography and imaging devices, in particular to a voice coil motor carrier, a voice coil motor, an imaging device and a lens installation method. Background technique [0002] A miniature auto-focus camera generally includes a voice coil motor and a lens, and the voice coil motor is used to drive the lens to move along its optical axis to achieve auto-focus or zoom functions. [0003] Existing voice coil motors and lenses are generally assembled with threaded structures. The threaded connection method has specific standards for the number of thread meshing turns. If there is a problem with the selection, it will easily lead to problems such as out of focus, optical axis tilt, and field curvature. In addition, in the existing technology, glue dispensing is also used to assemble the lens and voice coil motor. The position of glue dispensing will directly affect the relative position of the lens and voice ...

AI Technical Summary

Problems solved by technology

[0007] The above-mentioned voice coil motor carrier extends toward the axis of the second opening to form a limiting part, which is used to hold the peripheral side of the lens, effectively blocking dust and other impurities from entering the carrier, thereby improving the imaging effect; through the boss Supported by the lens, the gap between the boss and the lens is filled with a layer of glue, which avoids the problem of uneven shrinkage of the glue after curing at a constant temperature and affects the tilt of the lens, and improves the imaging quality
