12.2.2 Vision cursor teaching

Vision cursor teaching allows you to obtain position data which is more

accurate than normal point teaching. A teaching window with any desired

size is displayed on the vision monitor and its center position obtained. The

target mark or pattern must be displayed on the vision monitor.

1 Clamp the PCB on the conveyor and set teaching condi-

tions.

As with point teaching, clamp the PCB on the conveyor, and set teaching

conditions by executing the <2/1/B0 TEACH, TRACE CONDITION>

command. In this case, the teaching unit must be set to “Camera”.

2 Move the camera to the target position.

Check safety and stay out of the axis movement range, then manipulate

the YPU joystick to move the camera to above the target position.

3 Press the [Ctrl] + [F10] keys.

A teaching window appears on the vision monitor as shown below.

4 Adjust the teaching window position and size to match the

pattern or mark size.

At the top left of the vision monitor, the coordinates of two diagonal

corners of the window are displayed. Adjust the window position and size

to match the pattern or mark size as follows:

1. When an asterisk (*) is prefixed to each of the two coordinates as

shown above, pressing the arrow keys allows the window to move in

the direction indicated by arrow.

Use the arrow keys to move the window so that its upper left or lower

right corner is properly positioned for the target land patterns or mark.

2. When you press the [TAB] key, the asterisk (*) of the right-hand

coordinates disappears as shown in the figure below. This state allows

you to enlarge or reduce the window size by changing the position of

the upper left corner with the arrow keys (the lower right corner is

stationary in this case). Adjust the window size to match the pattern or

mark size.

3. When you want to adjust the window size by changing the position of

the lower right corner, press the [TAB] key again. The asterisk (*) of the

left-hand coordinate pair disappears but an asterisk reappears at the

right-hand coordinates, as shown in the figure below. This state allows

you to enlarge or reduce the window size by changing the position of

the lower right corner with the arrow keys (the upper left corner is

stationary in this case).
