How to replace consumable parts

Separate the belt drive pulley from

the shaft.

1. Use a hex wrench (2.5) to loosen the

bolts on the coupling.

2. Disconnect the coupling from the drive

pulley to allow a gap through which the

belt can be taken out.

Detach the belt from the conveyor.

Detach the conveyor belt by taking it out

through the gap between the coupling and

the drive pulley.

53617-N9-00

Clean the guides and pulleys.

1. Use a vacuum assembly (option) to

suction the belt wear debris on the belt

guides and sensors, etc.

2. Use a plastic spatula or similar tool to

remove the belt wear debris adhering to

the outer peripheral surface of the

pulleys.

3. Use a brush or similar tool to remove the

belt wear debris caught in the belt

guides.

53618-N9-00

CAUTION

Use a plastic spatula and brush to avoid scratching the

pulleys and guides.

CAUTION

Do not use a solvent (IPA, etc.) unless the guides and

pulleys are excessively dirty. If using a solvent, be

careful not to spill the solvent on the bearing in the

pulleys during cleaning.

How to replace consumable parts

Reattach the belt.

1. Temporarily place the belt on the belt

tensioner pulley.

2. Place the belt on the end pulley

detached in Step 4 and mount it with the

pulley shaft together with the washer.

3. Connect the coupling to the drive pulley

and tighten the bolts.

4. Move the belt tensioner pulley to the

position marked in Step 4 and tighten the

bolt while applying tension.

5. If there is a slack in the belt, adjust the

position of the belt tensioner pulley to

apply proper tension.

NOTE

The speciﬁed conveyor belt tension for this machine is

as follows. Use a tension gauge to adjust the belt

tension as needed.

• Stage 1 : 260 to 320Hz

• Stage 2 : 180 to 220Hz

53611-N9-00

CAUTION

The tightening torque for the belt tensioner pulley is 5.5

N·m. Be careful not to overtighten.

Attach board clamp assembly.

1. Attach board clamp assembly to the

original position. Mount it by tightening 4

bolts with hex wrench (2.5).

2. Remove square cloth.

Return tape cutter duct to original

position.

How to replace consumable parts

3. Replacing the nozzle tip

When the nozzle tip or O-ring is worn out due to long-term use, pickup and placement errors are likely

to occur. If the spring action of a nozzle is not smooth even after cleaning and lubricating the nozzle, the

internal spring may need to be replaced.

3.1 Replacing nozzle tip and spring

Detach the nozzle.

1. Press the emergency stop button and

then open the machine safety cover.

2. Turn off the carriage clamp switch to

detach carriage from mounter.

3. Detach relevant nozzle with leaf springs

manually.

Replace the nozzle tip and spring

(Type 50X Series nozzles).

1. Turn the nozzle tip 90 degrees while

pressing on it.

2. Detach nozzle tip by pulling it downward.

3. The internal spring comes out as the

nozzle tip is detached.

4. Replace the nozzle tip and/or spring.

5. Attach the nozzle in the reverse of the

above procedure.

53615-N9-00

Replace the nozzle tip and spring

(Type 720X Series nozzles).

1. Detach the O-ring from the nozzle. Use a

precision screwdriver if difficult to

detach.

2. Pull out the pin.

3. Replace the nozzle tip and/or spring.

4. Insert pin to mount nozzle tip aligning pin

with groove in nozzle tip.

5. Attach the O-ring. If the O-ring is loose or

worn out, replace it with a new one.

CAUTION

See each head unit on "2.1 Consumable parts" in

Chapter 1 to check that nozzle marking (example: 601A,

511A) on nozzle body matches type No. of nozzle tip.

Lubricate nozzle slide section.

See "1.2.1 Cleaning and lubricating nozzle

slide section" in Chapter 3 to lubricate nozzle

slide section.

Return nozzles to original position.

Return detached nozzles to the original

heads.

CAUTION

Make sure to return nozzles to original heads. If detached nozzles from nozzle station (option), return them to the

correct storage positions.
