Tape Feeder: *1
•
Check whether a tape feeder suitable for the selected com-
ponents is used.
Check the type and specifications of the tape feeder and confirm
that a tape feeder suitable for the selected tape is used.
•
Peel off the cover tape and turn over the carrier tape to con-
firm that the components in the cavities fall down due to their
own weight.
Confirm that the components do not stick to the tape.
Confirm that the tape is free of static electricity.
Confirm that the taping is conformable to the specified limits.
•
Check whether the peel strength of the cover tape is proper.
Refer to the instruction manual of the tape feeder and check the
peel strength.
Vibratory Stick Feeder: *2
•
Check whether the vibratory stick feeder is installed correctly.
Check visually how it is installed.
If the stick is not bent correctly, the components cannot be fed
smoothly.
•
Check whether the feed time in the component library data is
proper
Check this visually.
If the feed time is not proper, the machine takes a pick-up action
before a component is not fed completely.
•
Check whether the escape action (action of air cylinder) takes
place normally.
If not, the picked component may be off-positioned or fall down
while it is moving up.
Check visually how the escape action takes place.
Multi-Layer Tray Feeder (Option): *3
•
Attachment of Multi-Layer Tray Feeder
If the multi-layer tray feeder is not attached correctly to the tray
pallet, components cannot be picked up normally.
Confirm that the feeder is attached without any leeway.
•
Transfer of Pallet from Elevator (how the pallet is pulled out
from the elevator)
If the pallet is not transferred smoothly from the elevator, the com-
ponents may deviate from the correct position.
Check visually whether the pallet is transferred smoothly.
•
Tray Data (Parameters) in Component Library Data
Confirm that the tray data in the component library data is proper.
•
Tray Offset Values
Confirm that the tray offset values are correctly set.
Check whether the pick-up level in the component library data is
proper. *4
•
Check visually whether the pick-up level in the component library
data is proper. Refer to the component pick-up menus in the com-
ponent recognition test menus.
•
Perform the teaching operation on the pick-up location at the “PICK-
UP LOCATION” display. (Hierarchical Sequence: “TEACH OFF-
SET” Display → “PICK-UP LOCATION” Display)

1.1.4 Frequently-Caused Pick-Up Errors on Specific Feeder
0005-002 1-8 Tg0248-PM-ER
1. Cause and Remedy of Simple Trouble
Check whether the internal part of the vacuum nozzle is stained
or clogged. *1
If clogged, the vacuum nozzle may not be able to pick up a compo-
nent.
Refer to “Nozzle Stocker” in “6. Monthly Maintenance of Section 1
in Volume 4” and inspect the nozzles. If necessary, clean them.
Check whether the frequently error-caused vacuum nozzle is
stained. *2
Dirty diffusion plate will cause a component recognition error or false
recognition.
If sebum or oil, etc., adheres to the surface of the diffusion plate of
the vacuum nozzle, note the followings and clean the surface.
(Otherwise, component recognition may become impossible.)
Prohibited Items
• Use of Organic Solvents, Rag, etc.
• Any Practice which may nick the diffusion plate
Recommended Cleaning: Use an ultrasonic cleaner and wash
the diffusion plate in water for 10 to
15 minutes or less.
Blow off moisture on the vacuum
nozzle, using compressed air.
If the nozzle is still dirty, consult our
sales personnel for details.
Note: Do not use any organic sol-
vent, a rag, etc.
Wipe off dirt accumulated on the nozzle end with a lens cleaning
cloth.
Refer to “Nozzle Stocker” in “6. Monthly Maintenance of Section 1
in Volume 4” for details.
Check whether the data for the frequently error-caused nozzle is
proper. *3
When the data for the nozzle length is not proper, components cannot
be picked up.
Check the data for the nozzle length in the nozzle data.
