Description

Camera module frock tool and camera module focusing system Technical Field The application belongs to the technical field of camera focusing equipment, and particularly relates to a camera module tooling jig and a camera module focusing system. Background IPC is called IP camera, namely network camera, mainly including camera lens and image sensor. In the production process of the camera, the camera is usually required to be focused, and focusing refers to adjusting the distance between the lens and the image sensor. When focusing, the camera is usually fixed on the fixture, the test chart card is arranged in front of the lens, the optical axis of the lens is vertical to the test chart card and coincides with the center of the chart card, the image signals collected by the lens are transmitted to the computer and displayed on the display screen of the computer, and then the distance between the lens and the image sensor is adjusted by an operator until the image displayed on the display meets the definition requirement. However, the current fixture is generally customized according to the specifications of the cameras, one fixture is difficult to meet the installation and positioning of the cameras with different specifications, and the distance between the lens required by focusing of the cameras with different specifications and the test chart card is often different, so that one fixture is difficult to meet the focusing requirements of the cameras with different specifications, and therefore, the cameras with each specification are usually required to develop corresponding fixtures, and the problem of high manufacturing cost exists. Disclosure of utility model The application aims to provide a camera module tooling fixture and a camera module focusing system, and aims to solve the technical problems that cameras of each specification in the prior art are required to develop corresponding focusing tooling fixtures, and the manufacturing cost is high.
