1. Confirmation of Low Component Pick-Up Rate
(Handling Errors)
Check Procedure
(1) Check the following management information and grasp
the contents, the frequency, and the trend of pick-up er-
rors.
The management information can be checked on the main
machine side.
• Machine Performance Data and Component Handling
Errors in Management Data
• Nozzle Management Data in Management Data
• Head Management Data in Management Data
• Handling Error per Feeder Location in Pattern Program
Management Data
• Recall Handling Error
• Recall Component Recognition Error
(2) Check whether the vacuum pressure for component
picks is correctly adjusted.
Check the vacuum pump and pipes.
Refer to “Volume 3 Troubleshooting ” in the main
machine instruction manual for details.
(3) Check whether the proper vacuum nozzles are selected.
If not, components cannot be picked up.
When a nozzle having a small diameter is selected for
large components, components may not be picked up due
to lack of pick-up force.
(4) Check whether the component pick-up position is
normal.
If not, components cannot be picked up correctly.
Confirm whether the offset of the traverse axis, the tray
offset in the pallet, the tray matrix size, and the height
data of the tray and the component is normal.
(5) Check whether a problem exists in the transfer of
pallets.
Check whether a pallet bounds while it is pulled out from
the elevator or stored in it.
If the pallet bounds, the components in the tray may pop
out from the tray, making it impossible for them to be
picked up.
In this case, check the offset of the elevator.
(6) Check whether the tray is fixed securely.
If not, the tray will move while the pallet is pulled out or
stored, the tray position will be changed, and the pick-up
position will be shifted from the correct one.
