StepDot
StepDot revolutionises needle dispensing and sets new standards in this field. Decoupling the movement of the dispensing valve from the robot enables previously unattainable speeds for contact dispensing. Whereas frequencies of up to approx. 10 Hz were common until now, with StepDot technology over 100 Hz are possible.
This is realised via a dispensing head whose nozzle can additionally be moved in the x-y-z direction by means of piezo drives. While the robot follows its movement pattern without reducing its speed at the dispensing points, the StepDot performs the compensating movements necessary for precise dispensing. The low accelerated mass allows for extremely high dispensing dynamics.
Advantages
Combines the advantages of needle and jet dispensing
Up to 50% smaller dots than with jet dispensing
No satellites compared to jet dispensing
Up to 15x faster than needle dispensing
“Dot on demand” for optimum dot sizes
With StepDot, overlaps in line dispensing can be printed in uniform height and width, and corners can be individually customised with the “round corner” function. Dot sizes can be set individually via the “dot on demand” function. marco can also assist you to find the best robot solution. Our newly developed marc1 gantry system provides the optimum basis for StepDot application. To fully exploit the possibilities of StepDot, the robot must be highly precise and powerful. In addition, real-time communication is a basic requirement.
