1 Industrial Vision: Applications Precision alignments of (small) mechanical parts Precision alignments of (small) mechanical parts PCBs, SMDs, wafers, chips PCBs, SMDs, wafers, chips Contactless geometrical measurements Contactless geometrical measurements metal and plastic parts metal and plastic parts electronic components electronic components subassemblies subassemblies Quality inspection Quality inspection shadow mask shadow mask metal and plastic parts metal and plastic parts electronic components electronic components subassemblies subassemblies Industrial identification Industrial identification

2 Inspection of production faults Dimensions of cut pieces Dimensions of cut pieces Dimensions of produced bottles Dimensions of produced bottles Height of fluids in bottles Height of fluids in bottles Sealed plastic bags (e.g. wrapped cookies): count the number of grains (=dark spots) in the seal Sealed plastic bags (e.g. wrapped cookies): count the number of grains (=dark spots) in the seal Dirt, dust on electric sockets Dirt, dust on electric sockets Lead inspection of ICs Lead inspection of ICs

3 Diode body inspection 100% in-line check 100% in-line check 6 measurements / diode 6 measurements / diode 25 diodes / second 25 diodes / second Check under two view angles Check under two view angles Backlight image, 180 microsec. flash duration, telecentric optics

4 Diode body inspection telecentric optics shielding shielding conveyor belt conveyor belt flash illumination (180 µsec) flash illumination (180 µsec) camera PLC controlled PLC controlled Go / no-go Go / no-go Data logging Data logging Statistics Statistics 6 measurements 6 measurements Auto-calibration Auto-calibration

5 Inspection of CRT-connectors In-line inspection during manufacturing. Inspection during continues rotation of the connector. Stand-alone go / no-go check

6 ICOS Vision: inspection of IC leads Dual shadow vision system guarantees reliable and accurate 3D measurements on all the leads. Dual shadow vision system guarantees reliable and accurate 3D measurements on all the leads. Switching lights eliminate the need for multiple sensors or motion. Switching lights eliminate the need for multiple sensors or motion. Where as single projection systems only look at the side of the leads, the ICOS solution reconstructs a true 3D image of the component. Where as single projection systems only look at the side of the leads, the ICOS solution reconstructs a true 3D image of the component. These raw 3D data are further analyzed to calculate reference planes and specific measurements such as lead coplanarity These raw 3D data are further analyzed to calculate reference planes and specific measurements such as lead coplanarity

7 Measurements Thickness of electric power cables Thickness of electric power cables Thickness of hot objects, soft objects (rubber parts) Thickness of hot objects, soft objects (rubber parts) Angle of diamond cone Angle of diamond cone Roughness of surfaces Roughness of surfaces Diameter of metal rings Diameter of metal rings

8 Ruler Absolute grey value independent Sub-pixel accurate 3 pixels / edge edges
