Application Notes
Industrial Barcode Verification of Two Codes
Medicine bottle labels include both a linear and a 2-dimensional barcode. The PresencePLUS P4 BCR reads both types simultaneously to verify that they are correct.
Verification of Two Barcodes on a Part
A part is tracked using both a linear and a 2-dimensional barcode. The high-resolution PresencePLUS P4 BCR 1.3 reads both types simultaneously to verify that they are correct.
Die Protection in Tire Manufacturing
The dies in tire presses suffer costly damage if the press tries to stamp the tread into an unstamped, or green, tire of the wrong size. To direct each tire to the correct press, Banner’s PresencePLUS P4 BCR 1.3 vision sensors sort green tires based on identifying information in the bar code printed on a label on the tire’s bead. In this application, the green tires moving on a conveyor pass below a fixture on which six BCR 1.3 vision sensors are mounted.
Label Inspection in a Wet Environment
A sealed PresencePLUS Pro COLOR vision sensor is encased in an enclosure that protects it from damage in a wet environment. The Pro checks for label presence and placement.
Automotive Weld Nut Inspection
After a robot inserts multiple weld nuts in an automotive component, a worker places the part onto an inspection station equipped with two PresencePLUS P4 OMNI vision sensors. Improperly inserted weld nuts could be missing, upside down, or tipped to one side. The PresencePLUS P4 OMNI inspects to see that the weld nuts are present, correctly oriented and not leaning.The vision camera compensates for part-to-part movement and can inspect from a long distance.
Automotive Duct Inspection
After a vacuum mass-airflow test of an automotive duct, a shuttle moves the PresencePLUS Pro into position above an open end of the duct. The PresencePLUS Pro verifies that a temperature sensor is still in place inside the duct and is undamaged.
Food Packaging Inspection
A high-resolution PresencePLUS P4 OMNI 1.3 mounted above a conveyor inspects each box of 12 chocolate candies, making sure each paper nest contains one candy and that the candy is intact.
