Checker Part Triggers
1 Internal Part Trigger: Checker uses its Part Finding Sensor to detect when
a part is present and ready to be inspected. You create and congure the Part
Finding Sensor by selecting a feature on your part that is always present.
2 External Part Trigger: Checker uses an external signal that your equipment
supplies to detect when a part is present and ready to be inspected. You use
an External Trigger by conguring a device such as a photoelectric sensor,
contact switch, or proximity sensor, then connecting it to Checker’s Trigger
input line.
3 Free Running: Checker inspects each and every image that it acquires, not
just the images that contain a part or for which an external trigger is received.
A part trigger tells Checker that a part is ready to be inspected. Checker
supports three trigger types.
Choosing a Trigger Type
In most cases, it is simplest to use the Internal Part Trigger, since no
external equipment is required. Simply create a Part Finding Sensor in the
Find My Part step.
If the appearance of your parts is highly variable, or if your line already
has a device or sensor that produces a part trigger signal, you can use an
External Trigger.
Free Running mode is useful for several types of applications:
Checking objects that move continuously and which cannot be
detected with a Part Finding sensor, such as a moving web of paper or
metal.
Checking parts that move in multiple ways, such as a part that moves
into the eld of view and then rotates in place.
Performing continuous inspection of non-moving objects to check for
changes in appearance.
