LABORATORY 12 - VISION SYSTEMS FOR INSPECTION

 

Purpose: To learn to use the DVT cameras as input sensors for PLCs

 

 

Overview: The DVT cameras are selfcontained vision systems. At the simplest these process images and perform checks that result in pass fail test results.

 

 

Pre-Lab:

1. Follow the tutorial for the DVT units.

2. Review the manual for the 630 camera at www.dvtsensors.com

3. Develop a system as suggested in the process below. This should include at least wiring diagrams and ladder logic.

 

Process:

The process will have a motor that drives a conveyor system. As parts move along the belt they are detected with a proximity sensor. When they move into range of the sensor the camera should perform a test for quality control. If the part is to be rejected a cylinder will fire and eject the part.

 

In-Lab:

1. Follow the DVT quickstart book to become familiar with the hardware.

2. Build the system designed in the prelab and select a ’part’ to test it with.
