7. Blow station

One blow station is installed in each stage. The blow station 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.

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 Side-view camera

The side-view camera is installed on the X-axis at the front of the multi-view camera. The side-view camera

recognizes horizontal images such as for the component pickup status, by using lighting installed for the

side-view camera. This allows the machine to detect component pickup errors and abnormal pickup, or find

dirt or debris adhering to the nozzle.

The side-view camera has the following functions:

Pickup error detection function

Normal mode

Detects component pickup errors to prevent "no placement errors".

Normal mode operates even when nozzles are changed after nozzle cleaning, etc.

Detail mode

Detects component pickup errors to prevent "no placement errors".

Checks for abnormal component pickups such as tilted, vertical or horizontal pickups based on the component thickness

tolerance set by the users.

Dirty nozzle sensing function

If the side-view camera shows "no component" even when the multi-view camera shows "component present", the

machine determines that the nozzle tip is "dirty" and a warning message appears. This serves as an accurate guide for

nozzle cleaning periods.

Component discard skip

This function skips the discard operation when the side-view camera shows "no component".

This eliminates unneeded operation when no component was picked up and prevents a loss of cycle time during

production.

Remaining component check function

This detects whether a component still remains at a nozzle tip after components were mounted or discarded.

Inverted component check function

In the recognition process after a component is picked up by a nozzle, this function checks if the front and back sides of

the component are inverted. It also simultaneously checks if that component size fits within the angle-of-view of the

side-view camera.

An error message appears if recognition shows the component front and back sides are inverted or that component will

not fit within the angle-of-view.

NOTE

Refer to "Programming Manual" for side-view camera parameter settings.
