(5) Open the “MANUAL AXIS OPERA TION” display and move the X/Y beams until they can be reached by hands. (Hierarchical Se- quence: “MANUAL MODE” Display “MANUAL AXIS OP- ERA TION” Display). (6) Set the [OPERA TION/SET UP…

Check whether the component pick-up position is normal. *1

When the component pick-up position deviates from the correct one,

it may have come out of the component recognition range or the

vacuum nozzle may have interrupted image capture, causing a com-

ponent recognition error.

Or, vacuum may have leaked out during component picks, causing

an error such as deactivation of a vacuum sensor.

Perform the teaching operation on the pick-up location at the “PICK-

UP LOCATION” display. (Hierarchical Sequence: “TEACH OFF-

SET” Display → “PICK-UP LOCATION” Display).

Check whether the component recognition is performed normally.

Confirm that there is no problem in the component recognition.

Refer to “1.2.3 Deterioration of Accuracy at Component Recognition

Camera Section of Section 1” for details and check whether the com-

ponent recognition is performed normally.

Check whether the selected components are deformed, making

it impossible for the vacuum sensor to detect them. *3

When the surface of components is not flat or is rough, the vacuum

leaks out, making it impossible for the vacuum sensor to detect such

components.

When it is designated to detect components by the vacuum sensor in

the component library, cancel the designation.

Check whether the vacuum sensor works normally. *4

Check how the vacuum sensor works.

Confirm that the vacuum sensor turns OFF when no component is

picked up and it turns ON when a component is picked up.

Check Procedure

(1) Open the “MANUAL SUBSYSTEM OPERATION” display. (Hi-

erarchical Sequence: “MANUAL MODE” Display → “MANUAL

SUBSYSTEM OPERATION” Display) Select the [BEAM-A AIR

SUPPLY] and [BEAM-B AIR SUPPLY] keys and press the

[MOVE] button to set to “OFF”.

(2) Select the [L**-AXIS VACUUM/BLOW] key and press the

[MOVE] button to set to “OFF”.

(3) Press the [I/O (DIO) DIAGNOSTIC] key. (Hierarchical Sequence:

“MAIN MENU” Display → “SPECIAL SEL.” Display → “DE-

VICE CHECK” Display → “INPUT CHECK” Display)

Then, press the [INP2-10] key and press the [NEXT PAGE] key to

open the 4th and 5th pages.

Confirm that the “L**-AXIS VACUUM SENSOR” is “OFF”.

(4) Open the “ZEROING OPERATION” display and zero the X/Y

beams. (Hierarchical Sequence: “MANUAL MODE” Display →

“ZEROING OPERATION” Display).

(5) Open the “MANUAL AXIS OPERATION” display and move the

X/Y beams until they can be reached by hands. (Hierarchical Se-

quence: “MANUAL MODE” Display

“MANUAL AXIS OP-

ERATION” Display).

(6) Set the [OPERATION/SET UP] switch on the checked side to the

“SET UP” side.

(7) Press the [READY] button on the checked side and release the

electromagnetic locks of the supply cover and the safety bar.

(8) Open the supply cover on the checked side.

(9) Make a component picked up by hand and check how the vacuum

sensor is changed over.

Open the display described in Step (3) and confirm that the “L**-

AXIS VACUUM SENSOR” is changed from “OFF” to “ON”.

Otherwise, check whether an error occurs with another vacuum

nozzle or change over the vacuum nozzle and check for an error.

Check whether the vacuum filter of the placement head is clogged

when an error is found in the sensor after a nozzle change opera-

tion.

Notes: (a) When the vacuum nozzle is attached, the threshold level

of the vacuum sensor is automatically set.

To set the threshold level again, open the “MANUAL

NOZZLE CHANGE OPERATION” display and change

the nozzle manually.

Do not attach any vacuum nozzle by hand.

Refer to “9. MANUAL NOZZLE CHANGE OPERA-

TION Display of Section 4 in Volume 1” for details.

(b) When the sensor does not switch over normally even

though the vacuum filter is normal, it may be broken down.

In this case, consult our sales personnel for details.

Refer to “Head” in “6. Monthly Maintenance of Section

1 in Volume 4”and inspect the vacuum filter.

Vacuum Pressure System

Check whether the vacuum pressure is correctly adjusted. *1

Set the [PASS/PLACE CHANGE] key to “PLACE” and turn off all

vacuum valves (LA1-, LA2-, LB1-, and LB2-axis vacuum/blow sole-

noid valves).

Confirm that "OFF" is set in the “STATUS” text boxes at the

“MANUAL SUBSYSTEM OPERATION” display.

Confirm that the vacuum pressure is -93 kPa (70 cmHg) or less.

When the vacuum pressure is too low, it is required to replace the

vacuum pump with a new one.

Consult our sales personnel for the detailed information on how to

replace or repair the vacuum pump.

Check whether the vacuum pump is producing any abnormal

sound. *2

Catch the sound of the vacuum pump and confirm that the sound is

not abnormal.

When abnormal sound is produced, consult our sales personnel for

the countermeasures.

Check whether the filter of the vacuum pump is stained or clogged.

Refer to “Vacuum Pressure System” in “8. Maintenance (Every 3

Months) of Section 1 in Volume 4” and inspect the filter.

Placement Head

Check whether the vacuum filter of the placement is stained or

clogged. *4

Refer to “Head” in “6. Monthly Maintenance of Section 1 in Volume

4” and inspect the filter. If necessary, replace the filter with a new

one.

Check whether the internal part of the vacuum nozzle is stained

or clogged. *5

If clogged, the vacuum nozzle may not be able to pick up a compo-

nent.

Refer to “Nozzle Stocker” in “6. Monthly Maintenance of Section 1

in Volume 4” and inspect the nozzles. If necessary, clean them.
