1.Check the setting value

(applicable value: 0.13 to

0.14MPa) of the cleaning blow

pressure. If it is not within the

value, modify the pressure.

2.Check the nozzle contamination.

If contaminated, clean the nozzle.

Check the length of the placed

component extending off the

board.

See 1-1-2-1 to 1-1-2-2

[Misaligned placement]

Check and adjust the PCB

recognition data (shape set) as

necessary.

Turn OFF the servo switch,

remove the PCB, and clean the

recognition mark.

Problem Cause

Check/Solution Reference

What if

The PCB detection

sensor on the

conveyor does not

detect the PCB.

(There is a cutout or

a slit at a detection

point.)

Error in setting the

length of the placed

component extending

off the board

The PCB detection

sensor on the

upstream process

conveyor does not

detect the PCB.

Two PCBs are

loaded.

The PCB stays on

the conveyor.

The PCB stays on

the entrance of the

upstream process.

PCB transfer error

A belt or a guide is

contaminated.

The PCB detection

sensor on the

conveyor detects

the PCB although it

does not exist.

PCB loading error

signal of the

downstream

process does not

turn OFF within

the PCB unloading

waiting time

Check the slit size of the PCB.

(Use within the limit of the notch

allowable dimension.)

1.Check the alignment of the

conveyor coupling to the

downstream process. If

necessary, adjust it.

2.Check the belt or the guide. If it is

contaminated, wipe it off.

Check the length of the placed

component extending off the

board.

Clean the belt or the guide.

Check the sensor for

contamination. If contaminated

wipe it off.

Check the PCB unloading signal

(BA signal) of the upstream

process. Adjust as necessary.

1.Check the alignment of the

conveyor coupling to the

upstream process. If necessary,

adjust the alignment.

2.Check the belt or the guide. If it is

contaminated, wipe it off.

Check the sensor for

contamination.

If contaminated wipe it off.

Check the PCB request signal

(READY signal) of the downstream

Process output.

Check the PCB unloading waiting

time. Adjust if necessary.
