Spring-action at nozzle tip

Lubricate the spring-action parts.

Using a precision screwdriver or similar tool with a

pointed tip, apply a small amount of turbine oil to

inside the spring-action parts.

Push the nozzle tip to move the spring-

action parts.

Push the nozzle tip several times so the turbine oil

spreads inside.

Wipe away excess oil.

Wipe clean around the nozzle with cleaning paper

or cloth that does not leave dust or residue.

Return the nozzle to the original position.

When the nozzle was on the nozzle station, place

it back there.

Periodic maintenance items

1.2 Inspecting ball screws and linear guides of each axis

Inspect the ball screws and the linear guides on the X, Y and W axes. Check the following points.

Checkpoints

1. Any foreign matter adhering to the ball screws and linear guides?

Check if any fallen chips have adhered to the X and Y axis ball screws and/or X, Y and W axis linear guides.

2. Do the ball screws and linear guides have the correct amount of grease?

Check if grease has flowed off or splattered in the air failing to adhere. Also check if grease has discolored or hardened.

3. Any abnormal sounds from the ball screws?

Press the emergency stop button. Then check for any abnormal sounds while pressing the head assembly or conveyor

table by hand along the X-axis or Y-axis back and forth.

Countermeasures

Dealing with problems found above

1.Ball screws and linear guides may be damaged when chips and other material bite into them. If chips are adhering, wipe

them off along with the grease or remove with tweezers, etc.

2.Apply grease while referring to “2.2 Cleaning and greasing the X and Y axis ball screws” and “2.3 Cleaning and

greasing the X, Y and W-axis linear guide rails” explained later on in this manual.

3.Consult your dealer when abnormal sounds occur even after trying the countermeasures in the above steps 1 and 2.

This section explains how to clean and lubricate a nozzle holder after inspection.

2.1 Cleaning and lubricating a nozzle holder

If the nozzle holder spring-action is poor, this adversely affects all operations of component pickup, recognition

and mounting operations. Periodically (once every two months) clean the nozzle holder with alcohol (IPA or

ethanol) and lubricate it with turbine oil to maintain smooth movement.

Press the emergency stop button.

The machine must be in emergency stop to ensure

safety during work.

Remove the nozzles and lower the heads.

Remove the nozzles attached to the nozzle holders

to be cleaned, and then lower the heads by

pressing the joint section.

Clean the nozzle holder by immersing it

in alcohol.

1. Place a cloth or absorbent paper under the

head.

2. Prepare a small container (for example, plastic

35mm film container) deep enough to hold the

entire nozzle holder. Then pour this container

about 80% full of alcohol.

3. Bring this alcohol container up against the

nozzle shaft so the entire nozzle holder is

immersed in alcohol for several seconds.

4. Remove the alcohol container and push up on

the nozzle holder with your finger several times.

Immerse the nozzle holder in alcohol

again.

Repeat steps 3 and 4 until the spring-action

becomes smooth.

Use air blow to remove foreign matter.

While placing a cleaning cloth or paper just under

the lower end of the head, insert the air blow gun

into the air joint section and blow air.

Lubricate the spring-action parts and

check the movement.

Apply turbine oil to the spring-action parts and

push up the nozzle holder by hand several times to

check that it moves up and down smoothly.

Wipe away excess oil.

Wipe away excess oil with cleaning paper or cloth

that does not leave dust or residue.
