Sick's Ruler3000 sets a new standard for high-speed 3D image quality in an easy-to-integrate, pre-calibrated device.
The Ruler3000 combines Sick's Ranger3 streaming camera with a Class 2 (eye-safe) laser, preselected optics and fixed geometries to enable much simpler set-up and commissioning. With industry-standard compliance and full access to machine vision software tools, the Ruler3000 dramatically reduces the time and complexity of integrating the most demanding inspection, measurement and robot guidance tasks in consumer goods, food and beverage production and packaging, tire and automotive production, pharmaceutical, battery and electronics production.
"With today's demand for higher throughputs, more precise quality control and flexible, batch-oriented production, the pressure is mounting for 3D machine vision systems to be faster and more accurate."says Sofia Nilsson, Sick's product manager for 3D streaming cameras.
Sick's Ruler3000 offers a perspective for OEMs, system integrators and end-users of 3D vision systems. With much of the configuration and commissioning work already done, a continuous stream of standard data can be quickly integrated into higher-level systems or robot controls. What's more, thanks to precise 3D, reflectance and scattered light measurements in a single device, several inspection aspects can be evaluated simultaneously, for optimum control and measurement confidence.
Ranger3, a powerful all-in-one streaming camera
Powered by Sick's ultra-sensitive CMOS sensor and innovative ROCC (Rapid On-Chip Calculation) technology, the Ruler3000 streaming camera digitizes reliably at fast production speeds. It processes up to 15.4 Gb/s, providing up to 7,000 full-format 3D profiles per second. The Ruler3000 extracts the true 3D shape of an object, whatever its contrast or color, and simultaneously captures grayscale and scattered light measurements, optimizing image processing and measurement accuracy.
The Ruler3000's high light sensitivity means that even very dark or highly reflective materials can be accurately inspected, while its HDR (High Dynamic Range) function enables components with widely varying light transmittance to be successfully captured in a single scan, such as tires and shiny metal assemblies, reflective or transparent foils, batteries and electronic component assemblies.
Outstanding performance, whatever the material
The performance of Sick's Ruler3000 on light, dark, reflective and contrasting surfaces, as well as its guaranteed field of view, make it suitable for high-end inspection and precise location tasks, when the camera is mounted above a conveyor or on a robotic arm. The 3D camera is therefore likely to save time for machine builders and end-users experienced in high-speed production in a variety of sectors.
In the food sector, the Ruler3000 camera can provide effective robotic guidance in demanding pick-and-place packaging applications, or for inspecting the presence of straws wrapped in transparent film and glued to beverage cartons.
In the automotive sector, it can be used to set up robotized glue dispensing inspections, or to accurately check the surface of electric car batteries for damage or defects. In the final inspection, tires are rotated to check for radial deformations, blisters and imperfections. The Ruler3000 easily inspects dark tire material thanks to its high light sensitivity.
In electronics and battery production, the Ruler3000 can be used to check the completion of complex assemblies such as shelves or detailed surface-mount assemblies, or to precisely inspect the surface of batteries for damage, defects and foreign objects.
In the pharmaceutical sector, for example, the Ruler3000 can be used to inspect the three-dimensional shapes of blister-packed drugs with great precision, in order to reliably identify surface errors and breaks.
Simple, versatile integration options
Integration is even simpler thanks to the user-friendly Stream Setup interface. Sick's new GenIStream API facilitates integration for C# and C++ users. Full compatibility with industry standards such as GigEvision and GenICam provides plug-and-play access to third-party software such as Halcon and LabVIEW. In addition, developers benefit from the full flexibility of Sick's AppSpace software development platform, with its wide range of image processing tools and sample applications.
Sick's high-precision Ruler3020 is one of six versions of the Ruler3000 product family. As an example, it provides 3D profiles up to 7 kHz in full format, or up to 46 kHz with a reduced region of interest. Measurements are expressed in millimeters with a Z resolution of 8-15 µm and an X resolution of 63-88 µm, guaranteeing very high definition for inspecting even extremely dark or reflective surfaces, as well as precision data for accurate robot guidance. Precise measurement values are guaranteed down to 8 µm in height.
The Ruler3000's factory-guaranteed field-of-view concept facilitates commissioning. With its compact design and IP65/67 protection rating, the Ruler3000 can be adapted to harsh industrial environments without the need to integrate costly protective devices into the machine.
