7. Blow station

In the nozzle shaft blow function, a blow station installed to the rear of the movable conveyor rail blows

high-pressure air internally through the nozzles and shafts to blow away dust and grit and clean the nozzles.

7.1 Performing a nozzle shaft blow

This section explains how to manually perform a nozzle shaft blow at any desired timing.

Open the [Unit] – [Head] tab screen.

Select the table and press the [Cleaning Blow] button.

A confirmation dialog box appears asking how you want to perform nozzle shaft blow, so press [Yes] or

[No]. (Press [Cancel] if you want to cancel nozzle blow.)

Pressing [Yes]:

Cleans all nozzles that are automatically changeable and set for cleaning blow.

Pressing [No]:

Makes a cleaning of nozzles that are currently attached to the head and set for cleaning blow.

Safety checks

The nozzle shaft blow function also contains the following safety checks.

• Nozzle shaft blow interruption alarm

The head immediately rises if operation stops during nozzle shaft blow due to emergency stop or an interlock triggering.

If the head rises but the air blow still continues, then the nozzle might come loose from the head. To prevent this, a

confirmation dialog box appears if the machine operation stopped during nozzle shaft blow.

• Nozzle sensors to check whether a nozzle is left on the blow station

The nozzle shaft blow function forces high-pressure air through the nozzles during cleaning, so the nozzles might come

loose from the head if machine operation stops during nozzle blow. If a nozzle comes loose from the head and remains

on the blow station while the automatic operation still continues, then the nozzle left on the blow station might interfere

with other heads or with the multi-max unit. To prevent this, nozzle sensors are installed so that the machine constantly

monitors whether a nozzle is left on the blow station.

An “interlock error” is issued if any of these sensors detects a nozzle on the blow station at any time other than when the

head is lowered during nozzle blow. The machine operation is then disabled.

8. Other options

8.1 QFP dump station

The QFP dump station (hereafter called dump station) is a QFP recovery conveyor designed to attach to the

feeder plate of a YAMAHA surface mounter. If a QFP is judged defective by vision camera recognition, that

QFP is temporarily placed on this dump station without being damaged. The QFP placed on the dump station

is then conveyed back at a specified feed pitch. When the dump station becomes full, the memory counter or

overflow sensor detects it and displays an error message before the next defective QFP is returned to the dump

station.

Photographs below show major parts and functions of the dump station.

Clamp lever

Use this lever to lock or unlock

the dump station to the feeder plate.

DUMP harness (signal cable)

Used to interface between the dump station

and the mounter for exchanging signals.

FEEDER harness (power supply cable)

Supplies power to the dump station from the mounter.

Manual operation panel

Use the switches on this operation panel

to set the feed pitch, move the belt at the

specified pitch and clear the count.

The LED lamps also show the

operation status.

Overflow sensor (option)

QFPs placed on the dump station

are carried back by the belt conveyor.

When a QFP arrives at the end of

the dump station, this overflow sensor

detects it and displays an error message.

Conveyor belt

Conveys QFPs placed on the

dump station at a specified feed pitch.
