Description
This function is provided in order to enable
you to set the camera and lighting correctly
for inspection. It is possible check the light-
ing, adjust the focus, and check gray levels.
This function automatically adjusts for posi-
tional or rotational shift in the target before
performing an inspection.
This function checks one by one letters or
symbols extracted within a set area to com-
pare with the character image registered in a
dictionary beforehand and reads the label
attached to the one in a dictionary in the
highest match (recognition values).
This data is the standard for recognizing the
characters.
Up to 5 dictionaries can be created and up to
40 labels (for letters and symbols) can be
registered per dictionary.
− Checks detected characters (or patterns)
against registered characters (or patterns)
on a character−by−character basis (or all
together).
− The character image being used as the
reference for the inspection can be re−regis-
tered via input from external equipment.
− This function finds target objects that
match the image registered in the template. It
detects the number and position of the
matches.
− Templates can be re−registered using ex-
ternal input.
This function counts the leads of ICs and
connectors and measures the width and
pitch of the leads.
This function detects edges and determines
the position and shape.
This function detects the average gray value
of a specified area.
− This function is used to output the data de-
tected by the various checkers to external
devices or for performing calculations using
the detected data.
− You can also set to detect whether the
calculated results lie within a set range (i.e.
you can set upper and lower limits).
The judgment results from each checker can
be output to external devices. It is also poss-
ible to combine multiple judgment results.
