Latest vision sensors for process inspection and quality control

February 2016 Sensors & Transducers

An example of this technology is the IV series vision sensor from Keyence of Japan. The series is programmed with customised parameters that correlate, for example, with the material thickness or the presence of a barcode. The CCD scanner head, the heart of the sensor, compares the object being tested with the preset parameters by means of a visual inspection process. When an object fails to match these parameters, the manufacturing process is able to react accordingly and an operator is alerted.

The sensors can test up to 99 inspection windows simultaneously, which not only improves the response time, but also helps to remove the element of human error in quality testing.

Older in-process detection systems had an array of different sensors, with one sensor responsible for detecting a particular feature of a product. This could amount to detection systems having as many as up to 80 different sensors. Therefore the development of a single-sensor vision sensor has resulted in significant cost-savings.

The IV series vision sensor is extremely user-friendly, allowing someone with no experience with vision systems to find their way around the software and start programming it within thirty minutes.
