 Count X / Count Y

The size of the test box in the X-direction is called ‘Count X’ and the size in the Y-

direction is called ‘Count Y’.

 Light

When examining the existence of the nozzle through the fly-camera, the lighting is the

decisive factor in determining the binary value of the pixel in the test box area.

Therefore, the area for examining whether the lighting system has a problem or not

must be set up in order to check any problem with the lighting conditions when

checking the existence of the nozzle through the fly-camera. At this time, insert the

biggest nozzle in the nozzle-holder to examine if the nozzle interferes with the area to

be checked.

This area is displayed in rectangular box shape in the vision screen.

 Offset X / Offset Y

When the distance from the cross hair center to this rectangular box (i.e. center of

the test box) in the vision screen is indicated in the Right-Down coordinate

system, the distance in the X-direction is called ‘Offset X’ and the distance in the

Y-direction is called ‘Offset Y’.

 Count X / Count Y

The size of the test box in the X-direction is called ‘Count X’ and the size in the

Y-direction is called ‘Count Y’.

Memo When activating the <Test> button, the Offset or Count cell must be

clicked.

The coordinate system in the following figure is obtained from the

cross hair center of the vision screen.

of the pixel for the certain area (test box) that is set using the fly camera.

When the binary value of the pixel for the area that is used to check whether the nozzle

is mounted or not is below 30%, the nozzle is considered to be mounted. If the value is

above 30%, the nozzle is not considered to be mounted. If a nozzle actually exists, the

value must be close to ‘0’, if a nozzle does not exist, the values must be close to ‘100’.
