2. Troubleshooting on Pickup Errors : Chap.5
(2) Machine-Based Factors
When a component has no problem, check the main body of the machine.
A failure can be tracked by checking if it occurs on a specic vacuum nozzle
or feeder slot No. (lane).
(2-1) Whenthevacuumnozzlehasbeenspecied:
Check the following items for the specied vacuum nozzle.
•
Check if the vacuum nozzle is abnormal.
•
Check if the vacuum line is abnormal.
•
Check if the vacuum ON/OFF valve is abnormal.
•
Check if the linear measure sensor is abnormal.
When a factory is dusty or a lot of components packaged in paper tapes are
used, the vacuum nozzles and their lters get dirty easily.
Therefore, it becomes important to clean the vacuum nozzles and lters
periodically.
Reference
Refer to "2.2 (1) Frequent Pickup Errors on Specic Vacuum Nozzle" in
"Chapter 5" for the troubleshooting.
(2-2) WhenthefeederslotNo.hasbeenspecied:
Check the following items for the specied feeder slot No. (tape feeder).
•
Check if the tape feeder is loaded correctly with components.
•
Check if the top cover tape is peeled off normally.
•
Check if the data related to the component picks is normal.
Reference
Refer to "2.2 (2) Frequent Pickup Errors on Specic Feeder Slot No." in
"Chapter 5" for the troubleshooting.

(b) When a tape feeder loaded with different components is installed,
the pickup position (data) must be checked and the feeder (B) offset
data must be cleared or modied for the new components after the
program change operation because it is prepared for the previous
components.
