The new high-speed, high-accuracy CV-501 Series vision system from Keyence is a first to include both a built-in LCD monitor and the option to connect to two cameras.
The new high-speed, high-accuracy CV-501 Series vision system from Keyence is a first to include both a built-in LCD monitor and the option to connect to two cameras.
As a single controller operates both cameras, the CV501 can simultaneously differentiate between multiple points, or measure the dimensions of large targets.
High speed comes from the use of a grey-search method for position adjustment in the rotational axis.
Exceptional accuracy is provided by the use of sub-pixel measurement.
The result is a low-cost, best-in-the-class, fully functional vision system.
Numerous different modes of operation are available to meet industrial demands for dimension, inspection and position measurement.
In the automotive industry, where robot control is crucial, the CV501 can be used to detect accurately the co-ordinates and orientation of a target position.
Sub-pixel processing ensures that it can easily carry out simultaneous measurement of both inner and outer O-ring diameters, for example.
In the food and pharmaceutical industries, where product and label confirmations are vital, position and rotation adjustment functions ensure accurate inspection of targets that are difficult to position.
Similarly, the CV-501 has a relative position mode, which permits accurate detection of liquid levels, regardless of vibrations.
For the metal industry, the CV501 uses normalised correlation processing for groove width measurement, while the position and rotation adjustment function ensures accurate dimensional measurement.
Where water transfer is crucial, for example in the semi-conductor industry, two-camera detection is used to measure the operation in the X and Y directions.
In a move designed to cut time and cost, the CV-501 Series is designed to operate as a stand-alone unit and does not rely on connection to a PC and its associated software.
However, an RS232C connection is available for optional PC communication, such as logging data.
The CV501 comes with a comprehensive set of optional accessories, including ring lamps, colour LCD monitors, adaptors for close-up work, a variety of interchangeable lenses and optical fitters for even illumination of shiny targets.
