    Inspection of automatic lathing

    In lathing defects may occur caused by a worn or damaged lathe steel. NOW has developed a vision system for automatic inspection of automatic lathing with high precision. Data is stored in a data base for traceability. The system can be built-in in the lathe, or mounted in a separate inspection cell.

    Test of safety critical software

    NOW’s vision platform AVT is used for recursive tests of safety critical software.

    During the development of the software, new functions are added, and bugs are corrected. At every new release, all parts of the software must be retested to see that the functions haven’t been altered in a unwanted fashion. This is a time consuming work if a tester must watch a display to check the functions visually. NOW has developed functions to make this automatically with use of a vision system, which has resulted in lower costs, higher quality, and a more content personnel.

    Quality control in 2D and 3D (TQC)

    Vision system (Tile Quality Control, TQC) for difficult environments with Firewire cameras and audio analysis. The system is used for inspection/quality control in roof tile production, both in 2D and 3D. The size of the tiles is checked, and defects in the surface and edges are detected by cameras, where micrometre-thin cracks are revealed. Additionally noise analysis is used for detecting hidden cracks inside the tile.

    The software is written in C++ using DirectShow and Microsoft Visual Studio.

    The hardware consists of a PC with I/O-cards and external PLC and photoelectric sensors, and is built with Bosch Rexroth strut profiles around the conveyor belt.

    The system is fully parameter-controlled and stores the statistics. The user can choose to save images and sound recordings for a follow-up. The system has a variety of custom variants delivered to the Swedish and Danish tileworks for different kinds of clay and concrete tiles.

    Inspection of bending

    Within a very short time frame, NOW developed a vision system for inspection of bending. The system with two Firewire cameras, lighting, control electronics and PC software, automatically inspected the bending of an tinned component pin. If copper was visible, the component was not to be used. The system looked for the colour of copper, which was very effective. The customer could easily change parameters via the PC user interface, to change for example how much copper that was allowed. Statistics were saved in a database tool.

    Vision system for inspecting dashboards

    NOW has developed a vision system for inspecting dashboards. The system is built using DirectShow and Microsoft Visual Studio .NET 2003. Cameras deliver images that are handled in real time. Possible parameters to inspect are: colour, intensity, shape, symbols, segment displays, LCD displays, indicator positions and indicator needle movement. The application encapsulates a scripting language that is easily configured through a graphichal interface. Optional controls/commands are carried out in sequence. The system communicates with the client’s control system via TCP/IP.

    CD inspection system

    NOW has developed an CD inspection system, to be integrated in a machine for manufacturing CDs. NOW made a market research and selection of the fast CCD line scan camera which loads an image of the CD-writer when it spins one revolution. The image is sent to one of NOWs developed frame grabber boards, where some image processing is performed in hardware. Afterwards the image is processed with software vision algorithms, developed by NOW. After that the image is searched for surface defects, etc. Over 400 machines were manufactured using this equipment.
