Middle frame detection of mobile phones such as millet/OPPO
-- Mobile phone frame appearance defect detection system--
The mobile phone middle frame appearance defect detection system is mainly used for defect detection of pitting, scratch, edge collapse, collapse point, indentation and other defects of the mobile phone middle frame (including 9 side areas such as two long sides, two short sides, four R corners and their arc positions). The system adopts mechanical arm feeding, dust removal and cleaning device, surround lighting and multi-angle camera, which can meet the photographing accuracy within 10um, solve the problem of uneven illumination of arc surface and plane surface in the middle frame of mobile phone, and achieve high detection rate and high accuracy.
The system makes a breakthrough by using a time-sharing stroboscopic controller, one stroboscopic switching imaging, and combining multiple light sources for different defects at the same position, thus solving the industry pain points of many kinds of product defects, difficult identification and limited space, and greatly reducing the number of cameras and stations.
