Vision system for dispensing precision

11-09-2020 | Intertronics | Subs & Systems

To assist manufacturers reach high levels of dispensing precision, even on inconsistent parts, Intertronics now supplies the FIS F4000AKIT-VISION Camera Vision System. The device is a modular plug and play add-on to Fisnar ADVANCE series dispensing robots and offers a powerful and intelligent CCD vision-based programming and fiducial adjustment system, for simple and complex dispense programs. The system enables manufacturers to improve quality and production yield while lowering processing time and costs.

The product is unique by way of two cameras, so manufacturers have the option to oversee dispense programmes live for extra process assurance. When the robot is operating a dispense cycle, engineers can audit a live, full-screen image displayed on the monitor to inspect the fluid is being dispensed correctly onto the component part. This is beneficial for affirming first runs of a new program, or for 100% affirmation on ultra-critical assemblies.

Also offered is a Height Sensor, which automatically adjusts the dispense tip height from the workpiece. By comparing the exact workpiece height against the original stored datum value in the robot program, any variation found in the workpiece height results in the z-axis coordinate data being automatically offset accordingly. Multiple height checks can be completed within one robot program in the event of multiple workpieces being processed or a single workpiece with varying heights.

Employing the supplied Fluid in Motion software, users can utilise the vision system to produce dispense programs. The operator uses the displayed camera image to move the dispensing needle to the precise dispense location, then sets the planned operation — such as dispense a dot or start a line.

“Dispensing robots provide a high level of repeatability in the placement of material,” explained Kevin Cook, technical manager at Intertronics. “F4000 ADVANCE Desktop Dispensing Robots are robust and durable systems for long term precision dispensing. Where parts have some irregularity, camera-based vision systems can improve precision further, guaranteeing fluid is dispensed at the exact required location.

“For manufacturers who value precision, such as in aerospace or motorsports, or in highly regulated industries like medical device manufacturing, Camera Vision Systems can provide an added layer of control,” continued Cook. “This Camera Vision System is easy to install onto a F4000 Advance 3-axis robot due to its plug and play design. The hardware is mounted directly onto the robot, reducing space requirements.”
