Periodic maintenance items

1. Weekly or biweekly inspection

Inspect and clean the nozzles weekly or biweekly as explained below.

1.1 Cleaning a nozzle

If solder adheres to a nozzle tip, the nozzle may be mistaken for a component or other problems may occur. If

nozzle spring-action is poor or the nozzle tip is nicked, pickup errors tend to occur frequently. To prevent these

troubles, check the nozzle condition and keep the nozzles clean.

Remove the nozzle from the head.

Always first press the emergency stop button and

then remove the nozzle from the head.

CAUTION

When the machine is equipped with a nozzle station, make

sure that the nozzles are returned to the nozzle station.

Blow air onto the nozzle tip.

Use an air blow gun to blow air onto the nozzle

tip.

Clean the nozzle hole.

Pass the nozzle cleaning wire through the nozzle

hole and clean the nozzle hole. While holding both

ends of the wire with fingers as shown or using a

custom handle, gently move the nozzle back and

forth.

43301-5E-20

Blow air onto the nozzle tip again.

After removing the cleaning wire, blow air onto the

nozzle tip with the air blow gun.

Step 6

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.

43303-5E-20

Push the nozzle tip to move the spring-

action parts.

Push the nozzle tip several times so the turbine oil

spreads inside.

43304-5E-20

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 i-PULSE dealer when abnormal sounds occur even after trying the countermeasures in the above steps 1

and 2.
