9.2.18 Pickup and Placement Cycle For the Next Components
After all components in the first head cycle have been placed on the board, the gantry axes move
the placement head to the pickup position for the next pickup cycle.
The next pickup cycle is performed for components 13 - 24.
The subsequent pickup cycles are then performed in the same manner. The machine performs
repair runs where necessary.
9.2.19 Segment with a "Defective Component“
If the optical centering of a component (ident error) or the vacuum check before placement (alternatively,
CO recognition before placement) fails, the component will not be placed and will remain on the nozzle.
The turning station will still rotate this nozzle into the pickup angle for the new component , if this
segment is in the rotation position.
If this segment is in the pickup position:
the release procedure will be enabled,
the X/Y axes will move to the reject position for this gantry,
the star will rotate the segment into the reject position,
the component will be released downwards with air kiss
and the new component will be taken up.
The rejected component will then be placed in a repair run after all the other placement cycles for this
placement head have been performed.
9.2.20 Finishing Board Placement
The SIPLACE placement station enables the conveyor system and moves the board to the output
conveyor.
Finally, the SIPLACE placement station reports the number of components used (placed and
rejected) to the line computer.
The OIS (Operator Information System) compiles the placement statistics in relation to the
programmed settings, the programmed utilization and the last reset time. This detailed data is used
to optimize the process.
The machine is now ready for the next board.

9.2.21 Detailed Rotation of DP Station 1. Swivel In
9.2.22 Positioning into Pickup Angle
Diagram 1 shows the initial position (state after
reference run).
From the initial position, the stepping motor
rotates by 90° for swivel-in.
The DP station swivels in and contacts the
sleeve (incremental disk).
The stepping motor is monitored by the light
barrier on the cam disk.
Diagram 2 shows the status after swiveling in.
This is the start command for the DP axis
drive.
The DP axis positions the segment to the
relevant zero pulse and checks the signal level
at a distance of 3 digits.
An end position signal is emitted if the actual
position deviation is within the permitted
tolerance.
There is no difference between the 0° and
180° or 90° and
90° pickup angles.
