■
Fiducial cameras
RM head unit and HM head unit are equipped with this camera at side. This is used to recognize
fiducial marks and to perform teaching for components mounting position. The head unit has two
fiducial cameras at both sides in order to extend the sight.
■
Scan camera
HM head unit is equipped with this camera at bottom. After components are picked up, this camera
moves left and right to recognize the picked component while the head unit moves to the mounting
position. This has also the side-view function as standard.
■
Side-view camera
RM head unit is equipped with this camera at bottom. This camera takes from side the images of
component being picked-up by nozzle. RM head unit is equipped 4 side-view cameras and the rotary
rotates after picked-up component to move the nozzle picking-up component in front of the nearest
camera and then component recognition is performed.
