6. Placing Heads
The placing head picks parts from the feeders and place them onto the board
currently in production. The placing head assembly consists of the holder,
nozzle, shaft and other related parts.
6.1 How to Remove the Holder
Before removing the holder, the user must do the following four things:
• Move the holder to be removed to station 8.
• Move the XY table away from station 8 by hand. The holder is very
difficult to remove if the XY table is underneath.
• For safety's sake, turn off the power.
• To remove the holder, use a box wrench (MPJ-0072).
6.1.1 Removal
(1) Use the box wrench to
loosen the M6 hexagonal
nut under the holder.
(2) After removing the nut,
slide the holder down to
remove it. The spring
washer and washer will
also be removed so take
care not to drop them.

(2) The correct set position
looking from the front

hexagonal nut, spring
washer and flat washer
into the box wrench,
tighten these onto the
assembly.

6.2 How to Remove the Nozzle
When removing the nozzle, use nozzle removal jig MPJ-1100.
6.2.1 Removal
To remove the nozzle from the holder, follow the steps below.
These steps require the nozzle removal jig MPJ-1100.
(1) Rotate the nozzle by hand to a point where the nozzle catch is
facing the front.
(2) Set the nozzle removal jig, MPJ-1000, on the nozzle stem, as
shown in figure 6-3, and pull toward yourself. This disengages
the nozzle catch, allowing the nozzle to be slid out of the
holder.
Note: One hand should be placed under the nozzle to prevent damage in
case it shoots out.

6.2.2 Attachment
