7.4.19 Pickup and Placement Cycle For the Next Components
After all the components of the first head cycle have been placed on the board, the gantry axes move
the placement head to the pickup position of the next pickup cycle.
The next pickup cycle is performed for components 21 - 40.
The subsequent pickup cycles follow the same procedure. If necessary the machine performs repair
cycles.
7.4.20 Segment with a "Defective Component“
If the optical centering of a component fails (ident. error) or component recognition before placement
fails, the component will not be placed and will remain on the nozzle.
The turning station will still turn this nozzle to the pickup angle of the new component if this segment
is in area A.
If this segment is in pickup position:
The reject procedure will be activated and
the X/Y axes will move to the reject position for this gantry,
The component will be rejected to the reject box below, via air blast
The new component is picked 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.
7.4.21 Finishing Board Placement
After placing the last component, the gantry axes move the placement heads to the waiting position.
An optical nozzle scan is performed after the first board or after the relevant board (depending on
the scan parameters).
The SIPLACE placement station activates the conveyor system and moves the board to the
intermediate/output conveyor.
Finally, the SIPLACE placement station sends the number of consumed components (placed and
rejected ones) to the computer with the OIS (Operator Information System).
The OIS (Operator Information System) calculates the placement statistics referring to the
programmed station setup, the programmed panel or the last reset time. This detailed data is used
to optimize the process.
The machine is now ready for the next board.
