Technical Field
[0001] This utility model relates to the field of CAM hole appearance inspection for mobile phone films, and particularly to an OCT adjustment mechanism for CAM hole appearance inspection for mobile phone films. Background Technology
[0002] CAM holes typically refer to precise openings on screen protectors designed to house components such as the front-facing camera and sensors. These openings ensure that the screen protector does not obstruct these important functional parts, while maintaining the integrity and aesthetics of the screen. The CAM holes on screen protectors need to be very precise to ensure that they do not affect the normal use of the phone, including the camera's photo-taking function and the sensor's response.
[0003] The CAM on a mobile phone screen protector is usually photographed and inspected by a camera on a testing platform. During the inspection process, the position of the screen protector and the position of the CAM on it are not fixed, so the camera needs to be adjusted in real time. In the process of adjustment, the shooting angle of the camera is usually adjusted manually. This method is inefficient and has poor efficiency and quality, which is very inconvenient.
