Industrial Robotics

Industrial Robotics consists of many types of industrial robot arms and their applications. We also look at robotic end of arm tooling and how to use the different models available.

Industrial Robotics

The photo shows the Yaskawa Motoman SDA10D, twin armed robot. Primarily intended as an assembly robot or  machine tending, it certainly is an impressive looking robot!

Each arm has 7 axes of motion plus the rotate axis gives a total of 15 axes.

Payload is 10 kg per arm, so a total payload of 20 kg can be handled, if both arms are used.

The Pneumatic Robot

Pneumatic Robot

The pick and place machine is the simplest of the robots. Pneumatic powered, it has no servo motors driving the axes, but an air cylinder instead.

As such, each stoke is to an end stop, that is generally adjustable for a few millimeters, via a micrometer type screw.

A popular application is to pick and place small components into an assembly, maybe from a vibratory bowl feeder to an assembly fixture.

Pick and Place units are fast, accurate and very cost effective.

The Scara Robots

The Scara Robots

Scara means Selective, Compliant, Robot arm.

This robot is especially designed for assembly automation and uses 4-axes of motion, each axes driven by a servo motor. The two joints have a motor each and the base has a rotate axis.

The forth axis is the vertical axis that generally inserts a component. This arrangement makes a very "stiff" arrangement that is ideally suited for accurate insertion.

The Scara is the least expensive of the servo powered robots and are usually small and can be very fast.

The Gantry Robot

The Gantry Robot

This type of  robot is generally mounted direct to the shop floor and usually has a large work envelope.

It can  be used for material handling applications and I used them for stacking and de-stacking steel blanks, that were laser welded into tailored blanks.

They can be pneumatic powered but the cost of servo drives for industrial robotics is getting so competitive that today the air powered types are few and far between.

More details can be found by visiting this page - The Gantry Robot.

Cartesian robots

Cartesian robots

These machines are usually mounted on a table and are similar in concept to the gantry robot but on a smaller scale. The axes can be air or servo motor powered and are generally offered in modules, that are complete and can be bolted together, to form the motions required.

The photo shows a Toshiba robot.

The 6-Axes Industrial Robot Arm

6-Axes Industrial Robot Arm

Maybe the most recognized  industrial robot. It is available in a wide range of sizes and payloads,

They can be small enough to mount on a table or, like the ABB IR 140 shown here are floor mounted.

Applications are universal in the field of industrial robotics. The robot arm can be found in all types of uses, from assembly to welding to painting and material handling.

The Painting Robot

Painting Robot

When used in a painting application, the robot does not need a large payload capability but does need good repeatability and accurate path following.

When correctly programmed and well maintained, a paint robot will produce excellent repeatable results with no paint runs or overspray.

The Welding Robot

Welding Robot

The welding robot does not require a large payload capability but a larger work envelope can be an advantage and smooth, non-jerky movement is required.

Welding is a dirty operation, so sealing of critical areas is essential and the shielding gas used in MIG operations must ensure that weld spatter is kept tp a minimum.

Robot Grippers

A most important detail in industrial robotics is the part/ robot interface.

Grippers come in many sizes and different types. The photo shows an SMC gripper that is available in various bore sizes and is toggle operated. The toggle has the effect of increasing the clamping force and can provide gripping when pneumatic power is absent.

A visit to this page will give many details - Robot Grippers.

Robotic End of Arm Tooling

Robotic End of Arm Tooling

The E.O.A.T. ( End Of Arm Tooling), in industrial robotics, is an essential component of the whole.

Custom designed tooling can be very complicated. The fact that modular components are available reduces the technical risk and cost of many applications.
