The Benefits of Installing Variable-Speed Drive Compressors
January 8, 2025The Role of Compressed Air in Robotics and Automation
Kaishan USA | January 15, 2025| Uncategorized
Semiconductor handling relies on robotics and automation powered by compressed-air-driven pneumatics.
Pneumatic devices have been in use for a long time. Centuries, at least. So, it may be surprising that designers of some of our most advanced devices, including robotics and automation equipment, are turning to pneumatics. Deploying pneumatic actuators throughout robotics and automation equipment.
But it’s only surprising if you don’t know the advantages that compressed-air-driven pneumatics offers to creators of advanced equipment. And their ultimate customers, the end users of that equipment.
From pick-and-place machines to robotic arms used in automotive manufacturing to semiconductor handling devices, pneumatic actuators provide the power that is changing how we make products. Other applications include:
- Pneumatic grippers in packaging and assembly processes
- Linear actuators that operate valves or power assembly lines
- Pneumatic brakes
It’s a technology that offers benefits for both machine designers and equipment end users. Let’s start with equipment designers.
Why Machine Designers Like Pneumatics
Machine designers would be hard-pressed to find a power source that matches the performance of pneumatic systems:
- Strong. Pneumatic devices are stronger than comparable electric devices, delivering higher torque levels.
- Lightweight. Pneumatic systems do not require a motor or battery, so they are remarkably lightweight. That saves crucial fractions of ounces and allows designers to create ever-lighter robotic arms and assemblies.
- Small. Similarly, pneumatic devices are compact and take up less space, critical in today’s tight designs.
- Fast. Pneumatic actuators are faster than electric devices of a similar size, delivering more revolutions per minute (RPM). They react almost instantaneously, making them ideal for high-speed automation systems.
- Flexible. Because of their strength, speed and small size, pneumatic systems give designers of robotics and automation equipment a lot more flexibility and maneuverability.
- Precise. When equipped with electronic controls, pneumatic devices have positioning accuracy comparable to electromechanical and hydraulic systems.
- Versatile. You can design compressed air-driven tools to drive linear or rotary motion. They are dynamic enough to do almost anything you need. We rarely see a specification that a pneumatically controlled device can’t meet.
- Sensitive. Compressed air has a “cushioning effect,” according to the National Fluid Power Association, giving pneumatic devices a softer touch than is possible with hydraulics or electromechanical devices. Many designers value pneumatic systems for their pressing and squeezing ability, which can be critical in handling items that are fragile. And see how pneumatics can make moving a 10-ton compressor look like child’s play.
Compressed air has a cushioning effect that gives pneumatics a soft touch critical for automated handling of sensitive items.
Because of those unique advantages, you can expect designers of robotics and automation equipment to continue assigning pneumatics a critical role in developing even more advanced equipment. Such as human-collaboration “cobots,” currently mostly driven by electrical motors and drives, according to a recent article in Tech Briefs.
End-users, on the other hand, like the performance advantages of pneumatically driven equipment.
Why End Users Like Pneumatics
Pneumatic systems offer many advantages in end-use applications. And that all adds up to a lower cost of ownership:
- Safety. Compressed-air-driven pneumatics offers machine designers a wide range of advantages over other types of power. Pneumatic systems don’t rely on batteries and people aren’t electrocuted by compressed air. Compressed air doesn’t explode on the factory floor. And when it leaks, compressed air comes out as, well, air. No puddles on the floor. No slips and falls. In addition, pneumatically controlled braking systems can stop a piece of equipment, such as a train car, in the event of a power failure.
Pneumatically controlled braking systems, such as those on a train, can even bring equipment to a stop in the event of a power failure.
- Resistance to harsh environments. Pneumatic systems can withstand hostile environments, such as mining, where the use of robots reduces hazards to human workers. Pneumatic devicess perform better than other power sources, resisting heat, dust and dirt. Even corrosive chemicals, high radiation or underwater applications. And can handle temperatures from below zero to 200°F.
Pneumatic systems are better than other power sources in harsh environments or dangerous settings.
- Reliability. Air-powered tools such as sanders, grinders, spray guns and sandblasters hold up much better under constant use than electrical equipment and are not easily damaged. Generally, pneumatic systems have a longer service life than comparable electrical or hydraulic systems.
- Low maintenance. Because of their relatively simple design, pneumatic devices experience less overheating, less wear and fewer breakdowns. Maintenance intervals are shorter as well.
- Less downtime. With reduced maintenance requirements and fewer breakdowns, you will have less costly downtime.
- Cleanliness. You can purify compressed air to your heart’s content. With the right compressed air systems, you can even achieve purity that meets strict ISO 8573-1 (2010) Class 0 standards. Since the final output is air, compressed air systems do not cause pollution or contamination in the workplace, making them ideal for locations, like semiconductor fabrication, robotic surgery or food processing, where cleanliness is critical. At least in output, they are environmentally friendly.
Because of their inherent cleanliness, pneumatic systems power the robots used in surgery.
- Low initial cost. Pneumatic systems have a lower initial cost than comparable hydraulic and electrical motors and drive systems.
Low Cost of Ownership
Without even factoring in the performance advantages pneumatics offers, the combination of safety, reduced maintenance, less downtime and lower initial cost translates into a lower cost of ownership.
