Inspection for Head/Nozzle Clogging and Solenoid Valve

Breakdown

The following inspection must be carried out approximately once a week.

■ Inspection of Solenoid Valve

The switching valve of the solenoid valve may catch foreign matter causing air leakage. Air leakage will

turn the suction ON even if it is turned OFF.

As a result, the suction cannot be turned OFF after a component is mounted, and components may be

returned instead of being mounted on the PCB.

● Inspecting by selecting [Manual] – [Meas. Air pressure]

①Checking the maximum air pressure

Turn ON the suction and press the head tip with fingers to check the air pressure. The air pressure is

satisfactory if it is “600” or higher.

②Checking the head for clogging

With no nozzles placed in the head, turn ON the suction to check the air pressure. Typical air pressure is

approx. “70”. An error will occur if the air pressure is “180” or higher during vacuum check performed

after nozzle replacement.

③Checking the nozzle for clogging

With nozzles placed in the head, turn ON the suction to check the air pressure. “Nozzle clog criteria” has

been set for each nozzle. The air pressure must be below the criteria. If it is not, the nozzle will be

considered to be clogged and an error will occur.

④Checking the solenoid valve for switching failure

Turn OFF the suction and check for change in the air pressure.

- Press the head/nozzle tip with fingers and check for change in the air pressure.

- Turn ON and OFF the suction a few times and check for change in the air pressure.

If the air pressure changes even though the suction is OFF, air is probably leaking from the suction solenoid

valve.

NOTE: Do not disassemble the solenoid valve. Manufacturer’s guarantee will be ineffective if the solenoid valve is

disassembled.
