In the case of the Chip-Rect part that is fed by the tape feeder, the part pickup can be
done more accurately if the Pocket Teach function is used.
If a pickup error occurs during default operation, the machine tries to pick up the part
as many times as the set number of times of retry for the corresponding part. If the
number of times of the retry exceeds the last count, the machine creates an error and
stops operation.
However, in the case of the part that is fed by the tape feeder before the number of
times the retry exceeds the last count, find the correct pickup point by using the Pocket
Teach function and calibrate the pickup position before performing pickup.
The Pocket Teach recognizes the pockets or sprocket holes of the tape being supplied,
and calibrates current pickup position matches with the center of the pocket.
Teaching the Pocket Teach will reflect its result in the <PT> column in the <Grid>
group.
(ON-S: Successful, ON-F:Failed)
If the setup is performed so that the ‘Pocket Teach’ function can be executed during
automatic operation, this function is not applied when the <PT> column is OFF or
ON-F in the <Grid> group in the “Feeder Registration” dialog box.
Caution If the corresponding function is used while performing
placement, the pickup success rate of the corresponding
feeder can be improved. However, it takes time to perform
pocket teaching, and simultaneous pickup may not be
performed since the pickup point coordinate is
compensated.

Feeder Setup
Memo Performing pocket teaching will automatically reflect the offset
information obtained during pocket teaching and automatically
correct the home offset of the tape feeder. However, the corrected
offset value will be applied during the next feeding.
If the distance between the position recognized by the vision system
and the logical origin exceeds 0.2mm, the feeder ignores the
offset value.
A motor driven feeder using parts other than 1005/0603 parts does
not use the home offset adjustment function.
<Pocket Teach All> button
Performs the ‘Pocket Teach’ function repeatedly for all tape feeders with the <PT>
column being set to ON or ON-S in the <Grid> group in the “Feeders” dialog box
among the tape feeders installed in the corresponding feeder base.
<Pick> button
Performs pickup of the parts for the tape feeder presently selected in the “Feeder

alternately every time the Pick and Dump are clicked. When the pick-up is successful,
the following dialog box is displayed.
<Move to Fix Camera> button
It is activated only when the corresponding component is aligned by the vision
