COB-AF automatic focusing single shooting module and production process thereof

Abstract

The COB-AF automatic focusing single shooting module comprises a circuit board, a chip is arranged at the center of the top of the circuit board, a support is arranged at the position, close to the outer side of the chip, of the top of the circuit board, and an IR glass sheet is arranged at the center of the top of the support. A focusing motor is arranged at the position, close to the outer side of the IR glass sheet, of the top of the support, a lens is arranged at the center of the top of the focusing motor, and a connector is arranged on the outer wall of one side of the circuit board. According to the COB-AF automatic focusing single-shooting module and the production process thereof, the flexible circuit board, the wafer, the aperture, the lens group and the focusing motor are independently processed and seamlessly connected and assembled, so that the production quality of the automatic focusing single-shooting module is ensured, the production efficiency is improved, the rejection rate is greatly reduced, the production resources are maximally utilized, and the production cost is reduced. The lens group is driven by the focusing motor to move, so that automatic focusing of the single shooting module is realized.

Description

technical field [0001] The invention relates to the technical field of auto-focusing single-camera modules, in particular to a COB-AF auto-focusing single-camera module and a production process thereof. Background technique [0002] Videography is to use a camera to convert optical image signals into electrical signals for storage or transmission. In the process of videography, a camera module is generally required for videography. The camera module includes a single-camera module and a dual-camera module. The single-camera module consists of It consists of one camera. The dual-camera module consists of two cameras. The single-camera module is also fixed focus and zoom. The focal length of the fixed focus is fixed, and the scene in front of you cannot be zoomed in or out. The fixed focus is compared with zoom. The advantage is that the image quality is good, and the aperture is easier to enlarge. The disadvantage is that it cannot zoom, and can only rely on the movement of t...

Problems solved by technology

[0004] The purpose of the present invention is to provide a COB-AF auto-focus single-camera module and its production process to solve the problem that the existing auto-focus single-camera module in the above-mentioned background technology requires multiple devices for collaborative processing in the production process. It is difficult to achieve seamless coordination during processing of these devices, resulting in low assembly efficiency and low production efficiency of subsequent fixed-focus single-camera modules, and it is difficult to achieve precise focus adjustment for auto-focus single-camera modules.
