Nozzle taper surface
This is a part to chuck to the nozzle
holder of the placement head.
( Foreign bodies and contamination of the
taper surface and chucking groove can
cause an air leak and faulty chucking)
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
Nozzle changer upper surface
(Any contamination of the nozzle changer
upper surface allows contaminants to adhere
to the nozzle reflector, resulting in
recognition errors)

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)
This is the unit that stocks nozzles. The placement
head automatically changes nozzles before placing
components are changed.
