VISUAL INSPECTION
Registration Marking Identification Application

This solution uses an IMPACT camera to position a servo-controlled adhesive application system. The camera finds the coordinates of a registration mark on the substrate material, then sends those coordinates to a Programmable Logic Controller using Ethernet/IP communications.

 
PRESENCE AND ABSENCE
Automotive Assembly Adhesive Inspection System

Featured Tools: Contrast, Edge Point Find tools. Multi-camera application.

This application demo features a four-camera inspection system that verifies the positioning of adhesive beads on automotive panels. The four IMPACT devices shown in this application are set up in a master-slave configuration so that inspection results from 4 different cameras can be combined into one master vision device that is linked to the reject mechanism in the production line. This application demo features the power and flexibility of the IMPACT Control Panel Manager. Through a set of pre-configured panels, the easy to use setup screens allow operators to accurately detect for misplaced or missing adhesive.

 
Aluminum Wheel Inspection

This solution uses two IMPACT T20 cameras to ensure that the correct model of aluminum wheel is packed into the appropriate container before shipment. A multi-axis motion controller is used to control the camera positions for precise measurement.

 
MEASUREMENTS
Bearing Inspection

This application uses the image of a steel bearing assembly captured with an IMPACT A20 smart camera and a 3-inch diffused Red LED ring light. The IMPACT vision system measures the inner and outer diameters of the bearing raceway and verifies that it contains the correct number of bearings.

 
Aluminum Wheel Inspection

This solution uses an IMPACT camera to position a robot guidance adhesive application system. The camera finds the missing sections of adhesive, then sends those coordinates to a robot using TCP/IP communications.

 
COLOUR IMAGE PROCESSING
Color Fuse Inspection

Featured Tools: Contour Pattern Find and Color Checker

This application demo features a colored fuse inspection application where an IMPACT T23 Color Camera is used to inspect a fuse panel. This application requires the vision system to verify that each fuse is plugged into the appropriate location, and to check for missing and extra fuses. Using the Color Checker tool available in VPM, an ROI is placed over each fuse where a template of the individual fuse background color is trained. This same tool is also used to detect an absence of a fuse, or if a fuse is plugged into a location where it is supposed to be left vacant. In this application, the Color Checker tool alone is able to fulfill 3 inspection requirements, i.e. incorrect fuse; missing and extra fuse. Having the ability to fulfill multiple inspections with a single tool means faster inspection speeds so customers can achieve higher production throughput. This application example was developed by PPT VISION application engineers and is not specific to a particular installed application. The vision program is written so it can be used in other similar applications, such as color verification for wiring/cables, push buttons, or other similar colored products.

OPTICAL CHARACTER READING
Automotive Console Faceplate Inspection

This application uses the image of a steel bearing assembly captured with an IMPACT A20 smart camera and a 3-inch diffused Red LED ring light. The IMPACT vision system measures the inner and outer diameters of the bearing raceway and verifies that it contains the correct number of bearings.

 
Locating and Inspecting Circular Text

Featured Tools: Contour Pattern Find, Unwrap, and OCR tools

This application demo features a vision solution created to inspect the circular text printed on a randomly oriented oil cap used in the automotive industry. The vision program uses a Contour Pattern Find tool to locate a specific feature on the cap to determine it's orientation. Next, an Unwrap tool is used to "straighten" the curved text so the OCR tool can read the text accurately.
