(3) Control item

Select the control item with a radio button.

(4) Window type

Select the window type which is to be used during measurement with the

corresponding radio button.

If you do not select “Meas. (ONCE)” or “Meas. (SWEEP)” as the control item,

you cannot set the window type here.

Note: You can set the window type only for the MNLA head.

(5) Control button

Each control item can be executed with the corresponding control button.

The display of the control button differs among the control items.

1) Vacuum

The control item “vacuum” turns on and / off of the vacuum of the head

selected.

When “Vacuum” of the control items is checked, select the <ON>, <OFF>,

or <ON/OFF> button or press the F3, F4 or F5 key to control the vacuum

level.

The display of the vacuum level is updated when the control has been

completed.

2) Z adjustment

The control item “Z adjustment” controls the Z coordinate of the head

selected.

This control is necessary to pick up components using the nozzle.

When “Z adjustment” of the control items is checked, select the <UP>,

<DOWN>, <UP/DOWN> button or press the F3, F4 or F5 key to control

the Z-axis.

The display of the coordinates is updated when the movement has been

completed.

3) Z fine adjustment

The control item “Z fine adjustment” controls finely the Z coordinate of the

head selected.

This control is necessary to move the picked component to the laser

measurement height.

When the control items “Z fine adjustment” is checked, select <UP>,

<DOWN>, <LA control> button or press the F3, F4 or F5 key to control

finely the Z axis.

The display of the coordinates is updated when the control has been

completed.

4) Laser initial

This item initializes the laser sensor of the head selected.

When the control item “Laser initialization” is checked, select the <EXEC>

button, or press the F3 key to control the laser initialization.

5) Meas. (ONCE)

This item executes the laser measurement (ONCE) of the head selected.

The laser measurement (ONCE) is the function for obtaining the

information on the shadow shot with the sensor currently. The

measurement result is displayed in the “First” field of the item

“Measurement result” on the Laser control dialog box. (See Figure 8-2-4)

When the control item “Measurement (ONCE)” is checked, select the

<EXEC>, <LA control> button or press the F3 key or F5 key to control the

measurement.

The display of the measurement result is updated when the control has

been completed.

8 − 22

6) Meas. (SWEEP)

This item executes the laser measurement (SWEEP) of the head selected.

The laser measurement (SWEEP) is the function for detecting the smallest

shadow of a component according to the specified algorithm by rotating the

target component within the detection area. The minimum shadow width

detected for the first time is displayed in the “First” field of the item

“Measurement result”, and that for the second time is displayed in the

“Second” field. (See Figure 8-2-4)

When the control item “Measurement (SWEEP)” is checked, select the

<EXEC>, <LA control> button or press the F3 key or F5 key to control the

measurement.

The measurement result status is updated when the machine finishes

measuring.

7) Image display

This item displays the image data from the laser sensor of the selected

head.

When the control item “Image display” is checked, click the <EXEC> button

or press the F3 key.

Check to see if the laser level is within the range between 70 and 240, and

each value spreads evenly on the graph. If any value is lowered abruptly or if

any value is extremely low (65 or lower), clean the laser surface side of the

head.

Figure 8.2.5 Image display dialog box

− Laser level value: brightness of laser light transmitted from the

phototransmitter and received with the photoreceptor, that is indicated with

a figure between 0 (darkest) and 255 (brightest).

If a laser head is stained, this value decreases.
