AOI(Automatic Optical Inspection)<\/span><\/strong><\/h2>

\u00a0<\/p>

Industrial lenses are core optical components in automatic optical inspection (AOI). They achieve efficient defect recognition and precision measurement through high-precision imaging capabilities. The specific applications are as follows:<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

1. Appearance defect detection<\/strong><\/h5>

\u00a0<\/p>

Surface defect recognition of electronic components\u200c<\/strong><\/h6>

\u00a0<\/p>

Use low distortion, high-resolution lenses to capture subtle defects such as solder joints, printing defects and metal scratches (minimum recognition width is 0.3mm).<\/p>

\u00a0<\/p>

For example, in a company’s LED production line, industrial cameras are used with Fine-Lens filters<\/strong> to simulate human eye perception, and high\/low brightness information is collected in a single process, with an hourly detection efficiency of 220 brightness corrections and 120 color corrections.<\/p>

\u00a0<\/p>

\u200cHigh-speed continuous detection\u200c<\/strong><\/h6>

\u00a0<\/p>

Line scan lenses are adapted to roller transmission scenarios and support thousands of component detections per minute, such as expansion and crack recognition of lithium battery appearance.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

2. Precision dimensional measurement<\/strong><\/h5>

\u00a0<\/p>

\u200cTelecentric lens eliminates parallax\u200c<\/strong><\/h6>

\u00a0<\/p>

Maintain constant magnification when object distance changes, and achieve micron-level dimensional measurement (such as gear pitch, bearing inner diameter).<\/p>

\u00a0<\/p>

Combined with structured light technology, detect geometric parameter deviations of inclined curved workpieces.<\/p>

\u00a0<\/p>

\u200cAutomated assembly monitoring\u200c<\/strong><\/h6>

\u00a0<\/p>

Real-time detection of missing, misassembled or out-of-place parts (such as screws, springs, chips), triggering sorting or alarm mechanisms.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

-\u200cLight source and algorithm collaboration\u200c<\/strong><\/h6>

\u00a0<\/p>

For reflective\/black objects, specific light sources (such as ring light and coaxial light) are used to reduce interference, and deep learning segmentation algorithms are combined to enhance defect recognition accuracy<\/p>

\u00a0<\/p>

4.Typical application cases<\/strong><\/h5>

\u00a0<\/p>

\u200cPCB board inspection\u200c:<\/strong><\/h6>

\u00a0<\/p>

Telecentric lenses identify solder short circuits, cold solder joints and micron-level line defects with an accuracy rate of >99%.<\/p>

\u00a0<\/p>

\u200cAutomotive parts inspection\u200c:<\/strong><\/h6>

\u00a0<\/p>

Sham lenses extend the depth of field to adapt to scratch and deformation detection of workpieces with height differences.<\/p>

\u00a0<\/p>

Industrial lenses promote continuous breakthroughs in AOI systems in accuracy (some reaching 0.01mm level), efficiency and stability by adapting to different optical designs (such as telecentric optical paths, Sham tilt angles<\/strong>) and standardized mounts (C\/CS mounts).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
