WARNING
RISK OF HEAD CRASH 3
When the placement head is changed from the TwinHead to the Collect&Place head, the Twin-
Head's stationary component vision camera, P&P (type 33) 55 x 45, and stationary P&P compo-
nent vision camera (type 25) 16 x 16 digital must be removed, otherwise the Collect&Place head
will collide with the camera housings.
The
component vision module
is used to determine:
– the precise position of the components at the nozzle and
– the geometry of the package form.
The
PCB vision module
uses fiducials on the PCBs to determine:
– the position of the PCB,
– its rotation angle
– and the PCB skew.
The PCB cameras are fixed to the bottom of the gantries. They use fiducials on the
feeder mod-
ules
to determine the exact pick-up position of components, which is particularly important for
small components.
