The AI uses images to determine good parts from bad. After an image is registered, the target's brightness and shape are used to automatically determine which target features should be inspected during operation. This image-based method provides stable detection of targets that are difficult to handle when using conventional sensors with light intensity-based detection.
The AI Series can be used for a wide variety of applications. Examples include spring presence, label misalignment, screw tap presence, capacitor direction determination, and felt presence. In addition, the AI Series is capable of performing these detections over an area, which prevents errors due to variations in position or vibrations of targets.
With the AI Series, installation and tuning is incredibly simple. Because of the AI Series' ability to detect over an area, there no need to worry about mounting in just-the-right spot. This means less time spent designing the solution. The AI Series also features 2-touch tuning, similar to conventional Keyence sensors. Furthermore, users can see the current live view from the sensor, drastically reducing the time and effort required for installation and configuration.
IX Series image-based laser sensors can measure height anywhere within the area. Camera-based image recognition allows the laser to detect the height of the target point even when workpieces are not perfectly aligned on the production line. The height of where the laser hits the target will vary if the target is tilted or if the target itself is different, but the IX Series can identify the difference in height against the reference. For example, in a parts assembly line, a single IX Series unit can not only check for the presence of parts, but also perform seating checks and other height-based inspections. Thanks to its ability to detect height differences, the IX Series is also free from false detections and errors in the presence of glare from glossy surfaces of metal parts or when the detection target point has the same color as the background, offering stable automatic inline differentiation.
The AI in the IV2 Series vision sensor is specifically designed for presence and difference checking. Users need only register at least one OK and NG product image to complete setup. Brightness, focus, and detection are automatically configured by the AI, allowing for easy adoption and operation with no specialized image-based differentiation skills or extensive time and effort required. Setting operations are performed using a small amplifier with a built-in high-performance CPU, eliminating the need for a separate high-performance PC. The IV2 Series also offers the same ease of use as the IV Series, including intuitive operation with a compact amplifier and touchscreen monitor, and instant OK/NG notifications via the high-visibility LED mounted on the ultra-compact head with built-in lighting. Using AI for detecting features and setting conditions also greatly improves on-site usability.
Thanks to the integrated lighting, the IV Series is KEYENCE’s best-selling “simple and easy” vision sensor with a proven track record. In addition to color, shape, and edge-based differentiation, the sensors are also capable of character recognition (OCR). Automatic brightness adjustment and high-precision autofocusing mean users need only touch the detection target on the compact monitor to perform detection. Startup is also quick with a wide variety of analysis operations available in just 1 minute. The compact head is also equipped with high-intensity Hi-R illumination. Devices can be installed almost anywhere, and the built-in lighting provides bright, uniform illumination throughout the entire field of view for stable detection. The sensor head lineup includes ten different models to meet various detection, distance, field of view, and target size requirements.
