4.1.5 Checking the Wheel Position in Tape Feed Direction (Y
Direction)
Wheel Position Check
Check if the edge of the wheel is within the range of
standard value when it is positioned symmetrically with
respect to the cross hairs.
=HINT=
Make use of dimension gauges.
(Refer to ‘2.4 DIMENSION GAUGES FOR
OHP’.)
1. If within the range
Hold down the lever to proceed the wheel by five
crests and make checking similarly. (‘4.2 Tape
Feeder Operation Check’.)
=CHECK=
Repeat the step six times and if the edge of the
wheel falls within the standard range every time,
the position is correct.
2. If out of the range
Adjust the wheel position according to the below figure.
The standard range is described on pages 4.1−9 to
4.1−11.
=HINT=
Before measuring, ensure that the air conductor
of the feeder and that of the clamp stand have
been fitted properly without any gap.
=HINT=
Air may leak from the air conductor depending on the setting condition of the tape feeder on the
clamp stand.
In such a case, the position of the tape feeder is likely to be improper. Set it properly on the clamp
stand again.
