Nozzle holder
Spring for nozzle cushion
Dirt on this spring will prevent proper work of
the nozzle cushion.
Inner and outer circumferences of the nozzle holder
Dirt on the inner and outer circumferences of
the nozzle holder will prevent proper operation
of it, with the deterioration of the mounting
accuracy and a pick-up error.
Spring for nozzle clamp arm holder
This section holds the clamp arm. Dirt on the
spring will prevent proper operation of the
nozzle clamp.
Nozzle holder engagement face
Dirt on the engagement face of the nozzle
holder causes an air leak, because it will not
closely contact with the nozzle surface in
nozzle chucking.
This prevents the nozzle from picking up chips
properly and will deteriorate the mount accu-
racy and make false pickup.
Nozzle clamp arm
This directly catches the nozzle. Dirt on the arm will prevent
catching the nozzle, precision parts, lead to air leakage, and
cause wrong pickup and mounting.
Vacuum Filter
This is located on the air route and prevents dust in the air from coming into the machine. If
dust accumulates here, it will be hard to generate and break a vacuum at the tips of the
nozzles; therefore, the machine cannot display its true performance.
∗
The filter is expendable. If it accepts the ultrasonic cleaning, it will be clean outwardly;
however, the passing flow rate will not be restored, with a pick-up error and the deterioration
of the mounting accuracy.
Rolls of parts
Nozzle
Nozzle taper face
This is the part to be chucked by the nozzle
holder of the transfer head. The taper face or
chucking groove with dust or dirt will cause air
leakage or false chucking.
Nozzle reflector
This is the black resin part. To prevent the
surface from being dirty, the special coating is
given to it. Chips are recognized by reflecting
the LED light from the line camera. This part
with dirt will cause false recognition.
Nozzle tip (Nozzle)
This is the part to directly contact with and pick up chips. Dust on the sides can be the shadow in
recognition and cause the false recognition. Dirt in the pickup hole will cause false pickup.
