Problems solved by technology

[0005] However, on the automatic assembly line (assembly line), the products are stacked and stored in a top-down manner, and the above method will be very difficult to operate in the station
In addition, buffers and lubricants cannot be applied automatically at the workstation, and the position and amount of application of the camera lens module with resonance characteristics are different, and the frequency characteristic deviation will increase
Therefore, the defective rate of assembly of the camera lens module is increasing, and the productivity is low.

Abstract

The invention provides a camera lens module with an optical anti-vibration function. The camera lens module comprises a protective hood, at least one lens fixed in the protective hood, a lens frame which can be lifted or put down towards the direction parallel with an optical axis of the lens and is installed inside the protective hood, an OIS support which is used to fix the lens frame and installed inside the protective hood, a permanent magnet which is firmly disposed on the OIS support, an OIS coil which is fixed on the inner side face of the side wall of the protective good and faces the permanent magnet, and a conductor which is disposed in the protective hood and adjacent to the permanent magnet, wherein the OIS support is moved towards a direction intersecting the optical axis; and the conductor can generate eddy currents inside because of moving of the OIS support and the permanent magnet disposed on the OIS support.

Description

【Technical field】 [0001] The invention provides a camera lens module, in particular to a camera lens module with the function of reducing image instability caused by hand shake. 【Background technique】 [0002] Recently, not only portable cameras but also portable terminals such as smartphones and tablet PCs are equipped with high-performance camera lens modules. A high-performance camera lens module mounted on a portable terminal generally has an auto focusing function (auto focusing) and an optical image stabilization function (OIS: optical image stabilization). The optical image stabilization function is a function to reduce image instability caused by external vibration or user's hand shake. There are two types of optical image stabilization functions: the first is the lens shift type that moves the lens toward the direction intersecting the optical axis of the lens, and the second type is the image sensor that moves the image sensor toward the direction intersecting the...
