Cameras are the main accessories for electronic products such as mobile phones and tablets. With the popularity of smartphones, the number of mobile phone users is increasing, the demand for camera modules is also increasing, and the requirements for pixels are also increasing, which makes camera modules detection is becoming increasingly important.
The camera module structure mainly includes optical lenses, picture element photosensitive elements, digital signal processors, etc. The signal quality collected by the picture element photosensitive elements will have a decisive impact on the imaging effect of the entire camera. In order to ensure its quality, it is necessary to Detect and eliminate defects before assembly
Testing requirements:
Check whether there are dust, open circuits, short circuits, bumps, holes, dents and other defects in the photosensitive element.
Testing plan:
An optical imaging system composed of Huaxian Optics 900 series continuous zoom high-definition coaxial light lens, high-definition HDMI industrial camera, ring light source and cold light source control is used for inspection.
Detection renderings:
Solution advantages:
1. The use of high-definition HDMI industrial cameras can separate gold wires, gold balls, etc. from other parts and identify defects more clearly;
2. The light source uses LED annular epi-illumination ring light source, mainly considering the concave and convex changes of dust particles and the special material of the image sensor;
3. The lens uses the optical system 900 series continuous zoom high-definition coaxial light lens, which can provide a wider field of view and capture images faster.
