Intertronics has compiled a guidance note on how to specify a dispensing robot.
Automated application of adhesives, potting compounds or encapsulants, sealants, fluids or pastes provides productivity benefits over manual application, including consistency, speed and accuracy, but selection of a dispensing robot is sometimes a daunting task, the company says. When specifying a dispensing robot, it is important to understand that it consists of four main components: the robot itself; the dispensing equipment; tooling to attach the dispenser to the robot and to hold the parts to be dispensed on; and an enclosure to protect both the robot and its users. Each of these components can be specified separately, but need to be compatible with each other to ensure a complete and fully operational system. The equipment supplier should be able to assist with this, and may have suggestions for a complete system based on the customer’s application.
The list of considerations for the components of a dispensing robot include work area, z height, number of axes, weight of parts, weight of payload, load/unload process, accuracy, tolerance and repeatability. All of these are explained in greater detail in the full guidance.
Depending on application requirements, there are several dispensing methodologies to consider. The supplier should be able to help discern the most suitable methodology for the application and requirements, as well as with assembly and integration of the completed dispensing robot.
Once the dispensing robot has been specified, purchased and delivered, full training should be given to all users. This may be available from the equipment supplier.
“Automating the dispensing process can have significant effects on productivity and product quality," explains Intertronics Managing Director, Peter Swanson. "Robots, particularly benchtop robots, offer fast return on investment and a good level of capability when coupled with appropriate dispensing equipment. We have seen substantial improvements in consistency, speed, accuracy and reliability of the dispensing process with our customers who have implemented automated dispensing. This leads to cost savings in materials, production times and reduced rework."
“We have compiled 'How to specify a dispensing robot' to help others toward that first step in the process, but we are also happy to walk through the specification process in detail with technology manufacturers who are considering automating their dispensing process," he adds. "We can, of course, supply all of the components as a completed robotic dispensing system with process integration and training.”

Coriolis Composites has been selected by the National Institute for Aviation Research (NIAR) at Wichita State University (WSU), US, to provide a thermoplastics capable Automated Fibre Placement (AFP) system.
With its new ‘Process Live’ format, processing and manufacturing processes will become a visible focus of this year's Composites Europe exhibition in Stuttgart, Germany, on 6-8 November. Mechanical and plant engineering companies will get together in group exhibits to showcase their technologies in live interactions, enabling visitors to experience sub-processes in a larger context.
