Setting Inspection Area
Set the position and size of the area and the size of cells to detect edges of the object by the cells.
1.
Select "Area Setting" in "Smart Edge (Line)" setting window.
2.
Select "Area Setting" > "Change".
3.
Move the whole area by operating the ENTER key and press the ENTER key.
4
Specify "Start point (ST)" and "End point (ED)".
The start point is on the left and the end point is on the right in
the default condition.
Set the start point and end point along the edges to be
detected.
When the edges to be detected are located vertically, set the
start point at the bottom and the end point at the top.
The cell at the start point is set to No.0 and cell numbers
increase to the end point. Note that the scan direction of the
cells vary depending on the positions of start and end points.
The scan direction is set in "Edge Detect Condition".
5.
Set the size of the cell (WX, WY).
To change Width-X, tilt the Enter key left/right, to change
Width-Y, tilt it up/down.
The width parallel to the start and end points is Width-X, and
the right-angled direction is Width-Y.
6.
Tilt the ENTER key left/right to specify the number
of cells (N), and press the ENTER key to fix it.
Set the cells with no space between them from the
start point to the end point. The part with a space
between cells cannot be inspected.
If the number of cells increases and they overlaps each other, only two cells are displayed from the start
point.
If the cells are fully or partly covered with other cells, the scans are repeated in those areas. Although the
inspection is conducted thoroughly, note that the processing time takes longer as the number of cells
increases.
7.
After setting the number of cells is completed, press the CANCEL key.
How to exclude from inspection (Mask area)
Mask areas, where checker does no inspection, can be set in an inspection area. Set the first cell and end cell
to be excluded from inspection. The number of mask areas is not limited. Follow the same steps used for "Flow
Detection" checker.
