Microscan machine vision cameras in robotic inspection system
Microscan has been selected by Cross Company's Automation Group for an integrated robotic inspection system using the Universal Robots UR5 robotic arm and Microscan Vision HAWK Smart Camera. The vision-guided robot is a turnkey inspection system that provides final quality inspection of large components like automotive engines or large electronic sub-assemblies where multi-point inspection of the part is required in three dimensions. The system combines easy-to-use machine vision components with easy-to-use robotics, solving complicated inline inspection applications simply and safely for manufacturers.
In order to perform quality inspection of large components, multiple machine vision cameras are typically required because the component may be too big for the available number of pixels in a single machine vision sensor to capture all part features and complete all inspections in one image, or the inspections must be made from several angles around the component. This type of inspection is therefore not commonly automated because of the requirement for excessive equipment, mounting space, and complex configuration of all necessary tools. But this is where robotics, like the UR5 robotic arm, excel in simplifying all equipment into a single automation system. The UR5 system uses one machine vision camera in a dynamic application, where robot and camera communicate data in order to navigate to the necessary inspection points on all sides of the component.
In Cross Company's UR5 robotic inspection system, the inspection locations for a given part are communicated by way of a SKU that is read from a component as it enters the inspection point on the manufacturing line. This SKU initiates a machine vision job on the Vision HAWK Smart Camera containing all of the prescribed inspection steps for that component. As the UR5 robotic arm moves to the correct position, a command is sent to the Vision HAWK camera for the correct sub-inspection to perform at that location. The system keeps track of the cumulative results of all inspections and this collective pass/fail data is combined into an overall quality report for the component. The system can then perform new sets of inspections for new components coming down the line based on the unique SKU of each component, indicating specific inspection tasks. This modular process ensures automated quality control can be incorporated without downtime on the line, enabling a fully inline inspection step that is easily incorporated at any stage of manufacturing.
Microscan's Vision HAWK Smart Camera was selected for Cross Company's UR5 inspection system because of its fully integrated design, bringing together powerful inspection tools, image processing, advanced optics, liquid lens autofocus, and LED lighting all within one compact industrial machine vision camera. The camera integrates easily into equipment via RS-232 or Ethernet connections and can communicate over serial, Ethernet TCP/IP, EtherNet/IP, and PROFINET I/O protocols using the Microscan Link industrial connectivity tool, available across all Microscan machine vision systems.
Part of Microscan's AutoVISION family of machine vision products, the Vision HAWK Smart Camera takes advantage of a full suite of inspection capability and user-friendly technologies from Microscan's legacy of machine vision innovation. This includes the new CloudLink Web HMI, which is used in the UR5 robotic inspection system to display inspection results on a wireless tablet or smart phone using a web browser.
Cross Company's UR5 robotic inspection system was recently demonstrated at Automate 2015 in Chicago, where Microscan Machine Vision Promoter Dr Jonathan Ludlow hosted a Video Showcase of the live UR5 robotic inspection demo. Follow the link for more information about the Vision HAWK Smart Camera.
