Problems solved by technology

[0003] Manually rotate the focusing ring directly, the adjustment accuracy is low, and the most suitable position for focusing cannot be accurately grasped, and over-adjustment or under-adjustment often occurs, which increases the focusing time
[0004] For the focusing tooling structure of the AF (auto focus) model, the teleconverter is relatively close to the tooling module. When focusing, the hand needs to reach between the teleconverter and the module to rotate the focus ring. Due to limited space Therefore, the focus operation is extremely inconvenient

Abstract

The invention discloses a focusing device and a camera module testing device. The device includes a focus ring, a worm, a bracket and a driving part, the focus ring and the worm are both rotatably connected with the bracket, and the outer peripheral surface of the focus ring is provided with teeth matching the worm , the focusing ring and the worm constitute a worm gear mechanism, and the driving part is configured to drive the worm to rotate. The device has the characteristics of convenient focusing and high focusing precision.

Description

Technical field [0001] The present invention relates to the field of camera technology, and more specifically, to a focusing device and a camera module testing device to which the focusing device is applied. Background technique [0002] The back test line of the camera module usually has a focusing ring. When focusing on the camera module, you need to manually rotate the focusing ring. The existing focusing ring has the following problems: [0003] Manually rotate the focusing ring directly, the adjustment accuracy is low, and the most suitable position for focusing cannot be accurately grasped. Over- or under-adjustment problems often occur, which increases the focusing time. [0004] For the focusing tooling structure of AF (autofocus) models, the teleconverter is closer to the tooling module. When focusing, the hand needs to reach between the teleconverter and the module to rotate the focusing ring. Due to limited space Therefore, the focusing operation is extremely inconvenie...
