1-4-3 Cleaning and Lubricating the Nozzle

This part describes changing the nozzle holder set on the transfer head, the nozzles and the

vacuum filter, and also describes cleaning and lubricating the optional nozzle changer and the

nozzles set on it.

∗ For DU/DHU specifications, it is necessary to remove the feeder base cover for the maintenance.

“1-2-3 Setting and Removing the Feeder Base Cover (Only for DU/DHU Specifications)”

Flow chart

1. Selecting the operation table

2. Removal

a. Removing the nozzle holder from the transfer head

(Removing the nozzle from the nozzle changer)

b. Removing the nozzle from the nozzle holder

3. Removing the Vacuum Filter

4. Cleaning

a. Cleaning the nozzle holder

b. Cleaning the nozzle

(Cleaning the nozzle changer)

∗ The nozzle is not allowed to accept an ultrasonic cleaning. If it accepts the ultrasonic

cleaning, the nozzle reflector will corrode to cause a chip recognition error.

5. Setting (Changing) the Vacuum Filter

6. Cleaning the holder of the transfer head

7. Checking and setting the nozzle arrangement

a. Setting the nozzle to the nozzle holder

b. Checking the nozzle arrangement

c. Setting the nozzle holder to the transfer head

(Setting the nozzle to the nozzle changer)

8. Re-checking the nozzle arrangement

Tools

Cloth, air ejector, grease gun, syringe and tweezers

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.
