9. Other options

9.1 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.

9.2 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.

9.3 Coplanarity checker

The coplanarity checker measures lead linearity and coplanarity of QFP/SOP leads or BGA bumps at high

speeds, and determines "pass/fail".

The coplanarity checker has the following two functions:

• Coplanarity check

Inspects uniformity of the lead bottom against the seating plane of components having wire leads or solder balls.

• Component recognition height check

Prevents lead components from being mounted in an inverted position.

NOTE

For instructions on how to use the coplanarity checker, refer to the YS series programming manual.
