Place the camera adjustment jig on the top surface of the calibration block, facing its etching surface down.
Lines up to 2 on the etching surface of the camera adjustment jig must be clearly visible.
Loosen six SEMS cap bolts (1) that secure the camera, move the camera up and down, and when lines up to 2
on the etching surface are clearly visible, secure the camera in position.
Lines up to 2 must be

Concerned with camera recognition accuracy, it greatly affects placement accuracy and component pickup
reliability.
– Degraded placement accuracy when BOC mark is used
– Degraded bank recognition accuracy and teaching accuracy, resulting in poorer pickup reliability

Move the bad mark sensor to a point above the calibration block. Loosen the SEMS cap bolts (a) at two places
and move the BM lens holder so that the distance between the bottom surface of the bad mark sensor and top
surface of calibration block becomes 22 +0.5/0 mm. When the specified distance is reached, secure the bad
mark sensor with SEMS cap bolts (a).
Distance between the bottom surface of bad mark sensor and top surface of calibration block: 22 +0.5/0 mm
