1.3 Cleaning and lubricating the gripper nozzle (option)

The gripper nozzle that mounts a connector, etc. requires the periodic inspection and lubricating.

1.3.1 Inspecting the gripper nozzle

Checking the gripper nozzle condition

Move the grip of the nozzle with a finger. If it moves smoothly, there is no problem. If it moves back unsteadily

or is stuck in, the component pickup error or the recognition error may occur. Clean and lubricate the gripper

nozzle seeing the next.

Additionally, check that no wear or dirt is found in the grip or operation part. If the grip is worn out, replace

the nozzle.

Inspecting gripper nozzle

Example: Type30ALD nozzle

Grip is not worn out.

No dirt or dust is found.

Grip moves smoothly.

1.3.2 Cleaning and lubricating the gripper nozzle

Remove nozzles.

1. Press the emergency stop button and

then open the machine safety cover.

2. Remove nozzles from the head. If the

machine is equipped with the nozzle

station, press the [Nozzle Stn Shutter]

button to open the nozzle station shutter

and remove nozzles.

Clean the nozzle operation part.

If dust is found in the gripper nozzle

operation part, remove it with an air blow

tool (option), etc.

Periodic maintenance items

Clean nozzles with an ultrasonic

cleaner.

1. Put nozzles into a container (such as

beaker) in an ultrasonic cleaner.

Pour IPA in a container until nozzles are dipped.

3. Pour water in an ultrasonic cleaner.

4. Clean nozzles with an ultrasonic cleaner

for about 10 minutes.

Blow nozzles.

Take nozzles out from an ultrasonic cleaner

2. Air blow entire nozzle to remove IPA.

Intensively air blow the nozzle operation

part and the air path

533A4-L4-00

Lubricate the nozzle.

1. Apply turbine oil to a cotton swab or tip

of a precision screwdriver slightly.

2. Apply turbine oil to the nozzle operation

part.

3. Move the nozzle several times to spread

turbine oil to the nozzle operation part.

533A5-L4-00

NOTE

A thin coat of oil is enough to lubricate the operation

part.

Remove excess oil.

1. Remove excess oil by blowing the

operation part with an air blow tool.

2. Use a cotton swab or cloth to wipe away

excess oil around the operation part.

Check the nozzle operation.

1. Return removed nozzles to the head. If

nozzles were removed from the nozzle

station, once return them to the nozzle

station. Press the [Nozzle Change] button

to attach nozzles to the head.

2. Press the [Vacuum] button relevant to

the head on the [Unit] - [Head] screen.

Check that the gripper nozzle closes

smoothly.

3. Press the [Vacuum] button again to

cancel vacuuming. Check that the

gripper nozzle opens smoothly.

NOTE

If removed nozzles from the nozzle station, return them

to the nozzle storage positions.

1.4 Checking the conveyor sensor condition and operation

This machine uses a transmission type fiber sensor as the conveyor sensor.

As the conveyor width changes, the distance between the light emitting and light receiving sensors also

changes. Accordingly, the light receiving status of the sensor may change.

Therefore, a conveyor sensor tuning function is provided on this machine that stores the sensor light receiving

status after the conveyor rail width has been changed and automatically rewrites the sensor threshold value.

By changing the conveyor rail width periodically, you can check that the conveyor sensors and conveyor sensor

tuning operate correctly.

Checking the conveyor sensor condition and operation

Light receiving

53304-L4-10

Opzen the [Unit] – [Conveyor]

screen.

Press the [Width] button to change

the conveyor width.

In the "Conveyor Width" screen that

appears, enter a conveyor width and press

[OK] button.

The conveyor is changed to the width that

was just entered.

Check whether an error has

occurred.

The conveyor sensor is operating properly

unless an error message appears when the

conveyor width is changed. No further

check is necessary.

If an error occurred, perform "Conveyor

sensor tuning" from Step 4.

54300-L4-10

Perform the conveyor sensor

tuning.

1. Open the [Unit] – [I/O] screen.

2. From the "Output" drop-down list, select

"CONVEYOR".

3. Select "CONV SENSOR TUNING" (T01000E1)

in the output I/O list.

NOTE

In dual-lane machines, "T01000E1" corresponds to Lane

1, and "T01000E3" to Lane 2.

4. Press the [ON/OFF] button to switch the I/

O status from "0" (OFF)

→

"1" (ON)

→

"0"

(OFF) to perform auto tuning.
