Reference Run: Vacuum Value Explanation
After the CAN bus processor for the vacuum/air blast distributor has booted, the vacuum / air blast
distributor is initialized. This means that vacuum/air blast generator is adjusted to ensure that
neither vacuum nor air blast is generated at the nozzle.
The gantry axes move the Twin Head to the reject position.
●
Over the reject box the vacuum / air blast generator switches to air blast to reject components
and check the air blast.
●
The vacuum/air blast generator now switches over to vacuum and the open vacuum at the
segments is measured*.
●
After measurement, the pressure is adjusted back to 0 bar
●
The vacuum reference run has now been completed for the Twin Head.
*The closed vacuum value for the Twin segments relates to the calibration value.
5.3.3 Placement Process
Twin Head - Working Position
1. DP Axis
2. Z Axis drive
3. Incremental distance measuring system for
the Z Axis
All following procedures are for both Segments.
Twin Head - Placement Workflow
●
PCB camera centers fiducials after PCB is
clamped to determine the exact position of
the board in the machine.
●
Max. 2 components will be pick up from
feeder (1-per segment).
●
These components will be centered by
IC-camera and prepared for placement.
●
Place components on PCB.
