1、 How does the camera module focus?

1. Open and short circuit and electrical test to detect the electrical conductivity of the camera module.

2. In the black field test, the light shield moves downward, and the cover is arranged on the camera module to form a black field environment; First image recognition and height measurement, identify the position of the camera, and measure the distance between the lens and the detection surface of the laser rangefinder.

3. Focusing: the focusing instrument is inserted into the camera module and drives the camera module to rotate relative to the sound vibration motor to adjust the distance between the camera and the chart; Secondary image recognition and height measurement, identify the position of the camera, and measure the distance between the lens and the detection surface of the laser rangefinder.

4. In the white field test, the white field light source is horizontally close to and irradiates the camera module to form a white field environment.

5. The dispensing head can be close to or inserted into the gap between the camera module and the sound vibration motor for dispensing.

6. Curing: the curing light source irradiates the dispensing point on the camera module for curing operation.

7. In the activation step, the activation component controls the opening and closing of the camera module, and the camera module can take photos at least once to obtain photo information.
