7.2.3 Teaching Z-axis

For Z-axis teaching, the operator must first select the device with which Z-axis is to

be taught as described in the procedure given in 7.2.1 “Basic operating procedure”.

Only the head can be selected as the device. An error results with an alarm beep if

any other device is selected, and the operator must starts the operation from the

device selection.

This teaching is for height teaching. Lift down slowly the nozzle tip until it touches the

object for measurement, and measure the height. Never push the nozzle into the

object. After selection is made, the same method applies.

CAUTION

When you use the ↓-Z key to perform Z-axis teaching, the Z-axis

immediately moves down to the point 6 mm lower than the height you

set.

This may damage a nozzle, so do not perform Z-axis teaching around

the PWB transport rails (reference pin position or follower pin position)

or directly above a tall component.

7.2.4 Teaching vacuum value

Vacuum values are automatically set when component measurement is performed.

So, teaching is not necessary.

7.3 Teaching Recognition

7.3.1 Teaching of a Board Mark

The following describes the basic operating procedure for teaching recognition.

1. Move the cursor to the mark of the desired data position.

T o start teaching recognition, X- and Y-coordinates of the mark shall be entered

beforehand.

Figure 7.3.1.1

2. Press the CAMERA key on the HOD to start teaching.

The camera moves to the X- and Y-coordinates of the mark, and the selected

mark appears on the monitor. If the mark does not appear on the monitor, check

if the entered coordinates are correct.

If you do not use a camera as a teaching device, an error sound beeps, and the

machine cannot perform teaching recognition.

3. Use the +Y and/or –Y key of the HOD to select which direction the recognized

image data is to be rotated: positive or negative. After selecting the rotating

direction, press the ENTER key.

Note: The machine detects a white part as a mark. Whether the mark is

recognized as white or black with respect to the board color depends on

the contrast between the mark and the board, and on the light level for

the camera’s field of view. Normally, the mark is recognized as white. If,

however, there are lands, patterns, or silk printings around the field of

view of camera, the mark may be recognized as black with respect to the

board color. In this case, normal correction is impossible. Reverse the

black and white by pressing the +Y or -Y key on the HOD so that the

mark appears as white. If a mark is recognized as black against the

board, press the +Y or -Y key to reverse the black and white so that the

mark can be recognized as white.

4. Adjust the scale frame.

Set the top, left, bottom and right sides of the scale frame with the direction key

(+Y, -Y, +X and/or –X) to adjust the size of the scale frame

The FAST key changes the moving distance of the scale frame.

The camera picture and a rectangle frame appear.

Set the top and left scale frames first. Adjust them

so that they match with the top and left of the mark.

When adjustment is complete, press the ENTER

key.

In the same manner as above, set the bottom and

right scale frames.

When adjustment is complete, press the ENTER

key.
