Using Linear Actuators to Manufacture Cars

by Ajay Arora

When someone purchases a car, they expect their car to work the same way that all the others do. This requires an automated manufacturing process that is consistent across the whole industry. Human hands just aren’t able to create this consistency over long periods of time, so car manufacturers regularly turn to linear actuators in processes such as welding. More and more, the industry is turning away from pneumatic actuators and moving toward electric actuators.

Robots are great at doing things without any variation, but only if the parts of that robot are able to perform. If the actuator that controls the robot’s motion can’t perform the motion without any variation, you might as well get rid of the robots and have human hands doing the work again.

Why Electric Actuators?

Pnuematic actuators use the power of air to deliver force, but this power isn’t completely reliable 100% of the time. Pneumatic actuators experience fluctuations in the power over time, and this results in some of the welds being very weak while others have so much force the robot creates burn-through on the car. An electric actuator bypasses this problem because the force delivered is much more consistent than a pneumatic actuator.

Most car manufacturers spend a good deal of time worrying about how they can save money. Pneumatic actuator motors are large and cumbersome. This takes up more energy than it has to, and puts more strain on the robot, shortening its overall lifetime. An electric actuator is lightweight, and has a motor integrated onto it. This saves on energy, and allows to robot to move a little more easily.

Pneumatic actuators often have an external guide mechanism that can break down because of the heat and weld expulsion. Electric actuator can be shielded from these types of damage; sensitive components of the actuator are protected from extreme temperatures and contamination.

When you’re in the business of creating a product that people rely on every day, you are required to build something consistently over a long period of time. Today, electric actuators are up to the task with their reliable, precise and safe performance.
