Automatic adjusting jig for focusing of fixed-focus lens and adjusting method of automatic adjusting jig

Abstract

The invention discloses an automatic adjusting jig for focusing of a fixed-focus lens and an adjusting method of the automatic adjusting jig. The adjusting jig comprises a machine base, a rotating device, a driving device and a control device, wherein the control device has an electronic input interface used for acquiring image sharpness information of the lens and an electronic output interface that outputs a rotation direction and a rotation step length signal, the electronic output interface is connected to the driving device, the driving device and the rotating device are mounted on the machine base, the rotating device is provided with a mechanical rotating interface used for being connected with the lens, and the driving device is connected to the rotating device to drive the rotating device to rotate the fixed-focus lens according to the rotation direction and the rotation step length signal. Thus, the whole process does not need the participation of people, so that the workload of operating personnel is reduced, the production efficiency is greatly improved, artificial costs are reduced, the problem of a yield rate caused by visual fatigue of the operating personnel is prevented, and the yield rate is effectively improved.

Description

technical field [0001] The invention relates to the technology in the field of lens automatic focusing, in particular to an automatic adjustment jig for focusing a fixed-focus lens and an adjustment method thereof. Background technique [0002] At present, there are surveillance cameras and action cameras on the market. These cameras use a fixed focal length lens, which has been focused and fixed with glue when shipped. When focusing a fixed-focus lens, most manufacturers currently use manual operations, and the operator adjusts the image on the monitor to the clearest after aligning the fringe drawing. Since the definition is judged subjectively, not only is the accuracy difficult to control, but also workers who stare at the monitor for a long time are prone to visual fatigue, and twisting the lens for a long time may easily cause finger joint stiffness, which in turn makes production efficiency and yield unstable. Contents of the invention [0003] In view of this, the...

Problems solved by technology

Because the definition is judged subjectively, not only the accuracy is difficult to control, but also workers who stare at the monitor for a long time are prone to visual fatigue, and twisting the lens for a long time may easily cause finger joint stiffness, which in turn makes the production efficiency and yield unstable.
