Clamping device, clamping method and assembly method of optical lens and camera module

Abstract

The present invention provides a method for clamping an optical actuator assembly, the optical actuator assembly includes a motor housing, a motor carrier and an optical component fixed to the motor carrier, wherein the motor carrier and the motor The housing is movably connected; the clamping method of the optical actuator assembly includes: using a clamping device to clamp the optical component and the motor housing, wherein the clamping device includes a first clamp and a second clamp clamps, the first clamp clamps the optical component, the second clamp clamps the motor housing; and the relative positions of the first clamp and the second clamp are fixed, so that the optical The relative positions of the components and the motor housing remain unchanged. The invention also provides an optical lens, an assembly method of the camera module and a clamping device. The invention can avoid the movement of the optical component relative to the motor housing, and can improve the assembly precision of the optical lens and the camera module.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular, the invention relates to a clamping device and a clamping method for an optical actuator assembly, and an assembly method of an optical lens and a camera module. Background technique [0002] With the popularization of mobile electronic devices, related technologies of camera modules used in mobile electronic devices to help users acquire images (such as video or images) have developed rapidly and improved rapidly, and in recent years, camera modules Groups have been widely used in many fields such as medical treatment, security, industrial production and so on. [0003] In order to meet more and more extensive market demands, high pixel, small size, and large aperture are irreversible development trends of existing camera modules. However, it is very difficult to achieve the three requirements of high pixel, small size and large aperture in the same camera mold. For exam...

Problems solved by technology

[0005] At present, the jig only holds the motor during the active calibration and bonding process, but there will be vibration between the lower lens part and the motor, which will affect the effect of the active calibration, and after the active calibration is completed, the lower lens part needs to be glued The operation is to fix the first lens part and the second lens part. During the gluing process and curing process, the lower lens part will be shifted because it is not directly clamped by the fixture, which will eventually affect the optical lens and camera module. quality
