8.5 Transfer hook
The transfer hook located under the X-axis arm transfers the PCBs between
the carry-in conveyor, A/B tables and carry-out conveyor. When changing
the PCB type to be produced, adjust the transfer hook position so that it is
in the middle of the PCB width.

8.6 Push-up pins
The push-up pins are attached to the push-up plate by a magnet and used to
correct downward warping of the PCB. (When using these push-up pins,
set the PCB FixDevice parameter on the PCB Info. screen to “Pin+Push-
UP” or “Edge Clamp” (option).)

Check that the machine is in emergency stop.
If not, press the emergency stop button.
2
Place the push-up pins in correct position on the push-up
plate.
Considering the shape and size of the PCB, place the push-up pins on the
push-up plate so that they uniformly support the PCB, including the edge
of the PCB.
c
CAUTION
Set the push-up pins in positions where they will not interfere with the conveyor rails
and other parts when the push-up plate is raised.
3
Set a PCB on the conveyor.
Raise the main stopper with the MAIN STOPPER command in the
CONVEYOR UNITS menu, then set a PCB on the conveyor and place it
against the main stopper.
4
Raise the push-up plate.
Use the PUSH UP command in the CONVEYOR UNIT menu to raise the
push-up plate.
5
Check that the PCB is uniformly clamped on the conveyor.
Lightly tap on the PCB and also check for warping of the PCB from the
side. If the PCB is supported evenly with no warping, the adjustment is
okay.
Reference
It may be convenient to mark the positions of the push-up pins on the plate (with a label,
magic marker, etc.) for each PCB type.

8.7 Edge clamp (option)
The edge clamp secures the PCB in the mounting position by pushing
laterally on the PCB edge. If necessary, adjust the position of each edge
clamp unit according to the size of the PCB.

e
Remove the edge clamp whose position should be changed.
Loosen and remove the bolt securing the edge clamp and remove the edge
clamp along with the stay.
6
Reattach the edge clamp.
Attach the edge clamp in the proper position and tighten the bolt.
7
Check that the PCB is uniformly clamped on the conveyor.
Use the EDGE CLAMP command in the CONVEYOR UNIT menu to check
whether the PCB edge is securely clamped.
