Explains the method for greasing the nozzle holder using the 12-nozzle head as an example; however, the
same procedure is also applicable to the light weight 16-and 8-nozzle head.
Tool used: Syringe (BARRIERTA IEL/V)
Time required: 20 minutes for light weight 16-nozzle head, 15 minutes for 12-nozzle head, and 10 minutes for
8-nozzle head.

Refill grease to the oil groove at the clamp
claw
●With the clamp claw attached, apply grease using a small flat-
head screwdriver.
(To prevent grease from adhering to the portions around the
clamp claws)
●Grease: BARRIERTA IEL/V
●Wipe off any grease adhering to portions other than the oil
groove using a cotton swab.
●Be careful no grease adheres to the filter on the nozzle holder tip.
●Ensure that clamp claws are inserted to oil grooves before
installing the nozzle holder to the transfer head.

Nozzle taper surface
This is the part to be chucked by the
nozzle holder of placement head.
( Foreign bodies and contamination of the
taper surface and chucking groove can
cause an air leak and faulty chucking)
Nozzle reflector
This is a black-resin part. Parts are
recognized by reflecting the LED light from
the multi-recognition camera.
(Leaving this part dirty results in a
recognition error)
Nozzle tip (nozzle section)
This is the part that comes into direct
contact with a component and picks it up.
(Foreign bodies on the side results in a
recognition error. Leaving the pickup hole
dirty results in a pickup error)
Nozzle inside
(Foreign objects adhering inside the
nozzle hinder the pickup and placement
of components, and various detection
functions using vacuum pressure)
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
This is the unit that stocks nozzles. The transfer
head automatically changes nozzles before placing
components are changed.
Nozzle changer upper surface
(Any contamination of the nozzle changer
upper surface allows contaminants to adhere
to the nozzle reflector, resulting in
recognition errors)
