Nozzle inside
(Foreign objects adhering inside the
nozzle hinder the pickup and
arrangement of the support pins, and
various detection functions using vacuum
pressure)
Nozzle changer for support pins
Describes how to clean the nozzle and nozzle changer for support pins.
The cleaning method is as same as the nozzle
for component pickup.
(→P.6-4)
(It is not necessary to use ultrasonic cleaning
equipment)
Nozzle flange upper surface
The nozzle type and serial No. are shown
by the 2D code. The 2D code area is
recognized by the head camera.
(Leaving this part dirty results in a
recognition error)

Nozzle changer upper cover
●When nozzles are manually removed, turn the
nozzle flange in a counterclockwise direction
until it is not stuck with the hole of the upper
cover and remove it upward.
Nozzle changer upper surface
(Any contamination of the nozzle changer
upper surface allows contaminants to adhere
to the nozzle reflector, resulting in
recognition errors)
Cleaning the nozzle (option) and
nozzle changer (option) for
support pins 1
Nozzle tip (nozzle section)
This is the part to directly contact with
the flange of the support pin, and it
picks support pins up.
(Contamination on the vacuum hole can
cause an pickup error)
●A vacuum pad is installed for stable
pickup.
Nozzle taper surface
This is the part to be chucked by the
nozzle holder of the placement head.
(Contamination on the taper surface and
chucking groove may cause an air leak
and faulty chucking)
Nozzle reflector
Unlike the nozzle reflector for component
placement, this is the same material as
flange. This part checks whether the
nozzle is properly placed or not by
reflecting the LED light from the multi-
recognition camera.
(Leaving this part dirty results in a
recognition error.)
This is the unit that is used to stock support pin
nozzles. When support pins are automatically
changed upon changeover, the placement head
automatically changes nozzles.

Precaution when the nozzle vacuum pad for support pins is replaced
If the vacuum pad is not inserted all the way, it may reduce the accuracy of the support pin arrangement
position, resulting in support pin replacement error. When the vacuum pad is replaced, make sure to check
the insertion condition of the vacuum pad. Install the vacuum pad as shown below so that there is no gap.
Gap
The insertion condition of the vacuum pad can be checked from the vacuum side. Make sure to check if the
vacuum pad is installed all the way to the end of the metal flange.
