3) Vacuum

Set the vacuum value when a nozzle is mounted on the reference head (Head 3).

This value is used to judge whether a nozzle is mounted or whether a component is

located on the regulated position. Note that the value set here is just auxiliary

information since the system uses laser to check whether a nozzle is mounted or not or

whether a component is located at the regulated position.

4) Nozzle height

Set the offset value of the length with viewed from the reference nozzle.

This value is used to make fine adjustments for controlling the height when the system

measures a component with laser.

5) Single Assignment

When you press the <Single Assignment> button on the right side of the screen, the

system attaches a nozzle to the head of the ATC number in which the focus is located,

and sets each value.

Note 1) If the obtained nozzle outer dimensions are not within the regulated range

and the system judges that there is no registered nozzle information on this specified

nozzle according to its width, the following message appears on the screen. In this

case, select another nozzle, and enter data on the nozzle manually.

Note 2) If the obtained nozzle outer dimensions are not within the regulated range

and the system judges that there is any registered nozzle information on the specified

nozzle according to its width, select a nozzle number from the list of nozzles.

If the desired nozzle is not in the list, select it and manually enter its data.

WARNING

When you select <OK>, the axis is moved and a nozzle can be mounted

or removed. Be sure to check whether any worker is in the equipment

before pressing <OK>. To avoid a risk of injury, do not put your hands

inside the machine nor move your face or head close the machine while

the machine is operating

6) Automatic Assignment

When you press the <Auto-assign> button on the right side of the screen shown in

Figure, the following screen appears.

Check the check boxes corresponding to the ATC numbers to which nozzles are to be

assigned, and press the <Auto-acquisition> button. The system sets the nozzles to the

checked ATC numbers sequentially.

- The <Select All ATC Slots> button permits selecting or releasing all ATCs/all nozzles.

- Nozzle height is obtained by measuring the height of the attached nozzle tip.

- The nozzle number is set from the from the external diameter of the attached nozzle.

- The vacuum value to be obtained is set with the nozzle attached.

Notes:

- When you are to set two or more ATC slots automatically, the <STOP> switch allows

you to stop the automatic setting process. When you press the <STOP> switch

while the system is automatically setting the ATC slots, the system displays the

“Question” dialog box for stopping the automatic setting. When you select the

<Yes> button on this dialog box, the automatic ATC slots setting process is

terminated at this point.

When you press the <No> button, the process continues.

You cannot stop this process with the <CANCEL> button.

- When you automatically set the ATC slots, you do not have to enter any nozzle

number because the system sets it automatically. However, if the nozzle number

you set before this automatic setting operation is different from the one automatically

set, the latter is preferred.

- When you automatically set the ATC slots, you do not have to enter any nozzle type

either because the system sets it automatically. Note that the nozzle type is set to

“Normal.” However, the nozzle type you validated before this automatic setting is

preferred.

- If the width of the nozzle obtained with this automatic ATC slot setting process is

different from that of any standard nozzle, the system checks it with the information

on the customized nozzles registered.

When multiple nozzles have matching data, the Nozzle No. Setting List screen

opens. Make a selection from the list.

When they match each other, the nozzle number is automatically set.

If the width matches widths of two or more nozzles registered in the nozzle

information, the system sets the selected nozzle number to the ATC shown in the

“Nozzle no. table”.

When you press the <CANCEL> button at this point, the nozzle number does not

change if it is already set. Otherwise, the system does not set any nozzle number.

Manually enter it.

- If registered nozzle data does not match or nozzle data has not yet been registered,

the Nozzle Data Registration screen appears. At this time register the appropriate

nozzle data from the USB Flash memory.

7) Various

When you press the <Open> button of <Select ATC>, the ATC selected at Device

selection can be opened. When you press the <Close> button, the ATC selected at

Device selection can be closed.

When you press the <ATC Operation> button of the “Move Axis” column, the machine

moves heads to the ATC operation positions.

Vacuum value without nozzle

The system sets a vacuum value of each head on which no nozzle is attached, and checks

variations of vacuum values among heads.

If the value changes greatly when compared to the value set at filter replacement (about 10 % as

a reference), check and clean each head.

When you select the [Vacuum value without nozzle] command, the following screen appears.

(1) Setting items

No. Item Description

Change

filter

Obtains the vacuum value when no nozzle is attached. (Automatic obtaining only)

This setting item is used to judge the nozzle inspection and cleaning.

Nozzle

presence

check

Obtains the vacuum value to judge the nozzle attachment presence.

The obtained value is used as threshold value when the nozzle presence is judged

using the vacuum during origin return. (The value is updated even during origin

return.)

(2) How to set a nozzle

a) Acquire with the <ENTER> button

Press the <ENTER> button to get the vacuum value.

If a nozzle is attached to the head, the vacuum value is given after the nozzle has been

returned.

WARNING

When you click the <Exec> button, the axes move and the nozzle is

attached or removed. Before clicking the <Exec> button, be sure to

check to see if there is no one who operates the inside of the machine.

To avoid a risk of injury, do not place your hand in the machine, nor move

your face or head close to the machine.
