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.

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.

8) Edge Check

This item checks to see if the laser sensor edge of the selected head gets

dirty or dusty.

Move the head or nozzle above the laser surface, then execute this check.

To execute this check, click the <ON> button or press the F3 key when the

control item "Edge Check" is checked.

9) Edge check dsp (display)

This item checks to see if the entire laser sensor edge of the selected head

gets dirty or dusty, then displays the check result data.

To execute this operation, select the <ON> button or press the F3 key

when the control item "Edge Check dsp" is checked.

The following shows an example screen displayed when the "Edge Check

dsp" command is executed.

(6) State display

The ON/OFF status of the vacuum of the control head, Z axis coordinate, and

measured results by the laser are displayed when the control has been

completed.
