The Keyence IV series of vision sensors is designed to offer an affordable solution that's easier to implement than a vision system. It can be used for simple applications.
Keyence's new IV2 series is unique in that it directly integrates artificial intelligence. "The concept suggests something complex. Keyence's sensor is even simpler. Self-learning is the ability of a system to progressively modify its work program according to the greater or lesser effectiveness of its previous actions. In the case of this sensor, this takes the form of playful programming. You have to pass parts under the camera, indicating whether they are compliant or non-compliant. This is all it takes to program the vision sensor.stresses the company. Images can be added to the learning process to refine detection. Images can be added by varying the brightness, or by taking into account specific criteria such as whether or not to accept oil stains. Focusing is now within everyone's reach and, above all, this solution guarantees stability.
Automatic detection enhancement
The combination of lighting, lenses and the new processing unit means faster, sharper image capture and more stable detection over a wide field of view and at longer distances.
The IV2 series incorporates a new LED lighting system, called Hi-R, producing 30 % more intensity than the IV series. The shape of its reflectors has been optimized to ensure exceptionally uniform exposure. The high-performance HP-Quad Lens features four lenses for sharp, bright images. It minimizes the effects of distortion and reduces glare generated by bright targets. Two accessories also help eliminate reflections: a polarization filter for long distances and dome lighting for short distances. The latter enables indirect light to be emitted in several directions. It also improves target lighting uniformity.
In terms of processing, CMOS has also been optimized, for brighter images, greater speed and longer working distances. Images captured by the camera are processed at high speed, thanks to the image processing IC integrated into the head and the high-performance processor built into the amplifier.
A wide range of detection tools
In addition to the classic tools (width, pitch, OCR, edge, diameter...), a new control based on average color enables parts with different colors to be discriminated, by means of threshold definitions applicable to HSV average values (H: hue, S: saturation, V: value). It is complemented by a control based on average brightness and a new control based on target position, achieved by analyzing the color or brightness of the target within a given zone. These new tools make it possible to discriminate sensitive variations.
The IV2 Series adapts to any type of space and configuration. The sensor head is, according to Keyence, the most compact on the market (31 mm x 24 mm x 44.3 mm). It also features a 330° swivel connector. The large LEDs on the IV2 Series enable the status of the sensor to be checked at a glance, even when installed in hard-to-reach locations.
In addition to digital inputs, TCP-IP and SD card, the IV2 series provides immediate communication with native Ethernet-IP and Profinet, and DL Series gateways can be added for DeviceNet, CC-Link, Ethercat or Profibus communication.
Last but not least, the 5.7" control screen improves ergonomics on site.
