Spontaneous errors in the manufacturing process can be a thing of the past thanks to the new EventCam from SICK. This industrial-grade 2D camera brings clarity when unexplained gripping, handling and positioning problems arise or when unreproducible installation errors or machine downtimes occur.
The EventCam is specifically designed for the detection and analysis of sporadic errors in industrial processes. It can be integrated with great flexibility into stationary and mobile applications, is network capable, and delivers single frames and video sequences in ultrahigh image quality for detailed error analyses.
The optics, illumination, electronics and ring memory of the new EventCam from SICK are enclosed in a compact and rugged IP65 housing made from cast aluminum. The housing provides numerous mounting options that allow the camera to be installed in different positions, and these positions can be changed very quickly and flexibly. Configuring the camera is very simple: the resolution, output format, and trigger signal can be set with just a few clicks in SICK’s browser-based SOPAS Air software.
The EventCam has been specifically designed for fast and targeted error analysis. A connected automation system or sensor reports that an error has occurred in the process via the trigger input in the camera itself. The camera then begins storing single frames or video sequences.
At the lowest SVGA resolution, the EventCam can record up to 240 seconds before and up to 100 seconds after an event can be stored in the internal ring memory. If full HD is required, it can record 25 seconds before and up to 15 after, if in 30 frames per second (FPS). The video FPS can range from 13 to 65, depending on the resolution needed. In addition, EventCam can take photos of up to 15 FPS, taking 25 images before and 25 after in the highest resolution or 120 before and after in the lowest resolution.
In contrast to the time-consuming process of searching for an event in continuous video material, as provided for example by a GoPro or other streaming camera, the EventCam enables a targeted root cause analysis to be performed in just a few seconds or minutes. It is not necessary, either, to first upload the images and film sequences from the memory card – they can be accessed over the network in real-time at 100 Mbit/s via FTP and the Ethernet interface on the EventCam.
The EventCam not only enables a fast and detailed retracing of events in running machines and plants, but is also very useful when commissioning or optimizing them. The ability to quickly analyze errors in an unsupervised test run or a multi-hour/multi-day continuous test reduces the effort required to locate errors and therefore the time and costs associated with machine setup. The high mounting flexibility and simple configuration of the EventCam enables it to be used in a wide variety of machines, setup processes and tasks.
The EventCam is currently available in two identically designed variants. The version with a 0.4 m to 0.6 m working distance is primarily intended for stationary applications in machines, compact assembly, or pick-and-place robots.
The camera, with a 0.8 m to 6 m working distance, is designed for use in larger robots, handling gantries or machines. It also works well in safety applications in conjunction with safety laser scanner to take images of an area surrounding a machine. This enables users to see why downtime may have occurred and if, and why, someone tripped the safety scanner.
