(2) Details of Type Data
Type Name Type ID Nos.
This represents the regulated ID No. for type display regulation in the
"Type Listup" window.
The regulated ID Nos. are classied in the external le of the related
data. When the program is executed, the contents of this le is read and
registered in the regulation list box in the "Type Listup" window.
Inspection Type No.
Specify the number which represents the contents (method) of accuracy
inspection.

1: Inspection of Lane Origin Offset Adjustment
The origin offset position is inspected based on the design value
(position) of the target pickup hole.
The value is measured only in the Y-axis direction.
When the initial pickup hole is not located in the image processing
area, the position is shifted in the Y direction as much as the "Camera
Correction Pitch" specied in the system setting data.
The inspection position is moved to the place where the image
processing become possible.
As a result, the offset value for adjustment is calculated according
to the "CENTER" value (center value between "MAX." and "MIN."
values).
•
2: Inspection of Fiducial Mark Position Adjustment
An inspection is made to correct the pickup hole dislocated from the
ducial mark position.
The conrmation is made through the image processing of the
ducial mark before the pickup mark is inspected and he deviation
from the design value is stored in memory.
The pickup hole is inspected at the position where the pickup hole is
corrected as much as the shifted distance of the ducial mark.
The result of the measurement through the image processing of the
X and Y axes will be the result of correction equivalent to the shifted
distance of the ducial mark.
The result is displayed and "MAX.", "MIN.", "RANGE", and
"CENTER" values are displayed for each lane as the nal result.
Based on the "CENTER" value for each row (displayed here), the
value for feeder adjustment must be specied.

3: Simultaneous Inspections "1" and "2"
The lane origin offset and ducial mark position adjustments are
inspected at the same time.
The origin offset value for the Y axis is calculated according to the
shifted distance of the pickup hole based on the design value and
the shifted distances of the X and Y axes from the ducial mark are
recalculated and displayed after being inspected.
Each value displayed during the inspection represents the result of
image processing based on the position moved to the rst pickup
hole.
After all specied pickup holes have been inspected, the origin
offsets are gured out and the distances shifted from the ducial
mark are also calculated based on the result of origin offset correction
and redisplayed.
The results of judgment are based on the values obtained after this
recalculation.

4: Lane Origin Offset Adjustment, Recognition Mark Position
Adjustment and Sprocket Offset Adjustment
Note
This inspection type No. is used only for the GT/GD-28081 or
28083.
This complicated processing is used to perform the lane origin offset
adjustment, recognition mark position adjustment and sprocket offset
adjustment in a single inspection.
The same adjustment before the shipping from the factory is
performed in the case that the feeder feeding section is disassembled
or reassembled, or when it is disassembled to replace the part.
Because in the automatic type change, [Measurement Type 5] in the
next item is selected preferentially, so the measurement type should
be set in advance in the manual type change, when this adjustment is
to be performed.
Because the applicable GT/GD-28081 or 28083 feeder is for ne
components, the sprocket offset function is included to absorb the
sprocket peculiarity that affects the tape feeder position accuracy.
Therefore, the values including this sprocket offset value are
calculated.
The adjustment and inspection procedure after the master tape setup
is the same as for [Measurement Type 2] or [Measurement Type
3]. However, the measurement times are increased to calculate the
sprocket offset. In this case, any measurement can not be omitted.
Before the master tape is setup, the sprocket reference positioning
operation is performed.
Reference
Refer to the Item of "2.1 Operation Procedure for [Measurement
Type 4]" in "Section 4", for details.

5: Lane Origin Offset Adjustment and Recognition Mark
Position Adjustment
Note
This inspection type No. is used only for the GT/GD-28081 or
28083.
This complicated processing is used to perform the lane origin offset
adjustment and recognition mark position adjustment in a single
inspection using the sprocket offset value set in the feeder.
This [Measurement Type 5] is selected preferentially in the automatic
type change. The adjustment and inspection procedure after the
master tape setup is the same as for [Measurement Type 2] or
[Measurement Type 3]. Before the master tape setup, the sprocket
reference positioning operation is to be performed.
Reference
Refer to the Item of "2.2 Operation Procedure for [Measurement
Type 5]" in "Section 4", for details.
(3) Type Change
The type change method can be divided roughly into "Automatic Type
Change" and "Manual Type Change".
Automatic Type Change
After a certain type and serial No. are read, the corresponding type is
selected automatically.
In the type retrieval process, it is checked if the read type exists or not
by using the type name of the type data.
Note
When the specied type data is the same as the read one, no type
retrieval is made.
When the required type cannot be retrieved automatically, it is
required to create it.
