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.

(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 norma
l.

feeders.
(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.
