Nordson EFD, a major precision fluid dispensing systems manufacturer, has introduced the new RV Series 4-axis automated dispensing system.
The system features proprietary DispenseMotion software and a fully integrated CCD smart vision camera for best-in-class fluid placement accuracy and control at any angle along the 360° rotational plane.
Nordson EFD vision-guided dispensing robots use fiducial marks to automatically offset the dispense program and compensate for slight shifts in workpiece orientation or location.
DispenseMotion software compares the current workpiece location to a reference location that is stored as an image file in the program.
If the robot detects even the smallest difference in the X and Y positions and/or the angle of rotation of the workpiece, it automatically adjusts the dispensing path to correct for the difference. This allows it to achieve greater positional accuracy.
The RV Series software features a setup wizard that simplifies dispense tip-to-camera and dispense tip-to-workpiece offsets for faster setup and operation and features a powerful CCD camera that captures high-definition images for on-screen preview and confirmation of the dispensing path.
When paired with proprietary dispensing software, the camera makes the dispensing robot extremely easy to program, says the company. The 4-axis RV Series also delivers positional repeatability at +/- 0.008 mm.
“EFD’s DispenseMotion software allows for faster setup due to its ease of use and the introduction of the setup wizard,” said Johnathan Titone, Product Line Specialist – Automated Dispensing Systems, Nordson EFD.
“The integrated CCD camera allows you to see your dispensing path as you set the coordinates and parameters. We designed the 4-axis RV Series as a direct response to our customers’ growing need to be more productive by increasing throughput and first-pass yields.”
In addition, the RV Series features dispense tip alignment capability and true three-dimensional motion control to ensure the most precise fluid deposit placement, every time. Faster cycle and batch times and reduced material costs are just a few of the ancillary benefits claimed for the system.
