[ALL BM. HD. ZERO] Key
Both Beams A and B are zeroed.
When this key is selected and the [MOVE] button is
pressed, the zeroing operation starts.
[ECCENTRIC PT.] Key
When this key is selected and the [MOVE] button is
pressed, the P.E.C. recognition camera moves to the des-
ignated pick-up location correction position based on
the component center position (Position of “Design Po-
sition + Feeder (A) Offset + Feeder (B) Offset”) of the
pertinent feeder, making it possible to capture the im-
age. Under this condition, shift to the trackball opera-
tion and perform the manual alignment operation.
Note: It is necessary to correctly teach the component
center position before the eccentric position is
adjusted.
*6 “COMP. LIBRARY INFO./FDR. OFFSET INFO”
Displayed are the component library data and the feeder
offset of the feeder No. set up in *1.
*7 “RESULT X (mm), Y (mm)”
When the manual alignment operation (using the trackball)
is completed, the results of the teaching operation are dis-
played.

and “COMP. RECOG.” becomes light red. (No background
color in normal cases)

Operation Procedure
Basically, a component must be picked up when the nozzle is located at the
center of the component.
Therefore, “AUTOMATIC FEEDER AXIS ADJUSTMENT MODE” is pre-
pared to feed back and correct the positional deviation between the compo-
nent and nozzle center positions (the deviation calculated through compo-
nent recognition processing), using the statistical processing. However, there
may be some components which have a groove, a protrusion, etc., at their
centers, causing some hindrance to the component picks at the centers. To
cope with such components, the “PICK-UP LOCATION ADJUSTMENT”
function is prepared in the component library and can be selected to shift
the pick-up position intentionally from the component center.
The menus for pick-up location teaching are prepared to cope with each
case described before.
• Teaching Operation for Alignment of Component Center with Nozzle
Center
(1) Follow the teaching flow in Fig. 3.68 and perform the teaching operation
on the component center position.
When no regulation is given to the shape of components and positioning
should be made simply to the component center, use the [TEACH PICK-
UP POS. [COMP. CENTER POS.]] key.
Note: The teaching operation must be performed while “ALL BEAM
ZERO” is displayed.
Teaching Procedure
Designate the objective feeder No. for teaching.
Select the [TEACH PICK-UP POS. [COMP. CENTER POS.]] key.
Select the [CENTER 1-PT.] key or perform the “DIAGONAL
2-PT” operation.
Press the [MOVE] button.
The placement head moves to the objective
feeder position for teaching and the image of
the pick-up location is captured by the P.E.C.
recognition camera.
When the [CENTER 1-PT.] key is selected,
the registration of the designated nozzle is
made together for graphic teaching to facili-
tate the manual alignment operation with the
trackball.
Positioning Operation with Trackball
Refer to “Trackball Operation” (described
later) for details.

• Teaching Operation for Setting of Eccentric Pick-Up against Hindrance
to Component Picks at Center
(1) Follow the teaching flow in Fig. 3.68 and perform the teaching operation
on the component center position.
(2) Follow the teaching flow in Fig. 3.69 and perform the teaching operation
on the pick-up location correction position.
When a component has a groove, a protrusion, etc., and cannot be picked
up at the center without any hindrance, use the [TEACH ECC. PICKUP
POS [PICKUP LOC. ADJ] key.
Before teaching the data for “PICKUP LOCATION ADJUSTMENT” in
the component library data to intentionally shift the pick-up location from
the component center, it is premised that the component center position
should be grasped first. Therefore, be sure to select the [TEACH PICK-
UP POS. [COMP. CENTER POS.]] key and perform the teaching opera-
tion on the component center position. After that, select the [TEACH
ECC. PICKUP POS [PICKUP LOC. ADJ]] key to adjust the pick-up lo-
cation.
Note: When the center position is not grasped correctly and the teach-
ing operation is performed on the eccentric pick-up location, im-
proper values are fed back to “PICKUP LOCATION ADJUST-
MENT X, Y”, causing the component library data to lose its gen-
erality.
Teaching Procedure
Designate the objective feeder No. for teaching.
Select the [TEACH ECC. PICKUP POS [PICKUP LOC. ADJ] key.
Press the [MOVE] button.
An image is captured by the P.E.C. camera at
the pick-up location correction position of the
objective feeder for teaching.
The pick-up location adjustment data set up
at teaching execution is reflected.
Positioning Operation with Trackball
Refer to “Trackball Operation” (described
later) for details.
