5) Clamp a working PWB with the pusher Y, and adjust the clamping strength
with the reducing valve ⑮. For a thin and light-weighted board or fragile
ceramic board, set 0.2 Mpa as a guideline. For other type of boards,
adjust the strength with setting 0.3 Mpa to 0.4 Mpa as a guideline.
Figure 8.1.3.5
Notes:
①
You can adjust the shape reference position by using the [3/Conveyor]
command on the menu bar, and then the [1/Conveyor control] command
when the machine is turned off and the air valve is turned off also (see
Chapter 9, “I/O MANUAL CONTROL”).
②
When you move the stopper, be sure to re-enter the shape reference
position on the Machine Setup menu. Otherwise, the reference position
of the data is set differently.
③
When you transport a PWB whose specifications are the same, you do
not have to make any adjustment.
WARNING
To prevent the body from injury that can be caused by accidental
activation of the machine, turn off the power of the machine before
starting to work.
(5) Entering the position of the centering pin (skip this step when the board outline
is used for reference)
1) Turn on the power of the machine, and also turn on the air valve.
Perform zeroing (origin setting).
2) Select the [4/Setup] command on the menu bar, and the [3/Machine setup]
command on the displayed “Setup” menu. Select the [1/Set up group]
command, and the [4/Reference pin position] command on the “Set up
group” menu.
3) Click the <Support plate ON/OFF> button on the “Reference pin position”
dialog box to move up the support plate.
4) Move the input focus to the “X” or “Y” column, and press the CAMERA key
of the HOD. The OCC moves above the centering pin.
5) While viewing the vision monitor, teach the center of the centering pin.
(See Section 4.3.4 of “Machine Setup”.)
WARNING
To avoid a risk of injury, do not place your hand in the machine, nor
move your face or head close to the machine during operation of the
HOD.

(6) Entering positions for the use of Board outline reference
(skip this step for the use of pin reference)
1) Turn off the machine, and also turn off the air valve. Initialize the machine
(return each axis to its home position).
2) Select the [4/Setup] command on the menu bar, and the [3/Machine setup]
command on the displayed “Setup” menu. Select the [1/Set up group]
command, and the [5/Shape clamp position] command on the “Set up
group” menu.
3) Click the <Stopper pin ON/OFF> button on the “Shape clamp position”
dialog box to raise the stopper.
4) Set a board on the board transfer rails, then push it against the stopper ⑨
lightly.
5) Move the input focus to the “X” column, then press the [CAMERA] key of
the HOD. The OCC camera moves to the current outline reference
position.
6) While viewing the vision monitor, align the crosshair cursor with the outline
of the PWB (X direction), and press the ENTER key. Only a value of the
X coordinate is entered. Note that the PWB should be in contact with the
PWB guide and the stopper.
7) Align the cursor with the Y window, then press the [CAMERA] key of the
HOD. The OCC camera returns to the outline reference position.
8) While viewing the vision monitor, align the crosshair cursor with the outline
of the PWB (Y direction), and press the ENTER key. Only a value of the
Y coordinate is entered. Note that the PWB should be in contact with the
PWB guide. (See Section 4.3.5 of “Machine Setup.”)
WARNING
To avoid a risk of injury, do not place your hand in the machine, nor
move your face or head close to the machine during operation of the
HOD.

8.1.3.3 Adjustments of Other Parts
(1) Odd shape board
The board sensor may missdetect the board if the board is an odd shape board
such as the board with cutouts. Therefore, enter the PWB transport sensor
delay time according to the size of the cutouts.
For the odd shape board, the positions of the stopper and board sensor can be
changed.
a. PWB transport sensor delay
1) Select “6/ PWB conveyor” from “1/ Set up group” of the machine setup.
2) According to the length of the cutouts, enter the appropriate delay from
the keyboard. As a standard setting, set 60 ms for a cutouts of 30 mm
long.
Figure 8.1.3.7
3) If each PWB sensor does not detect the cutouts part of the board, delay
input is not necessary.
b. Stopper (Figure 8.1.3.8)
The stopper o can be moved in Y (plus, back) direction.
Move the stopper for the board which has a cutouts at its front edge.
1) Turn off the power of the machine, and also turn off the air valve.
2) Use the supplied ball driver to loosen the M4 hexagonal-headed bolt
that fixes the stopper assembly
24
, and move the stopper assembly
24
along the long hole of the stopper base
25
.
3) Tighten the M4 hexagonal socket head bolts
23
at an appropriate
position, and fix the stopper assembly
24
.
