Learn about pick and place robots
Definition and functions of pick and place robot
Pick and place robots are a type of industrial robot used to handle and place products on production lines. They are often used in high-volume manufacturing facilities, where they can quickly and accurately place products onto conveyors or other manufacturing equipment.
Components and features of pick and place robots
Robot arm: This is the main part of the robot and is responsible for moving objects. Robotic arms are usually made from aluminum or steel and have many joints that allow it to move in many different directions.
Gripper: This is the part that attaches to the end of the robot arm and is used to pick up and place objects. Clamps come in different sizes and shapes to fit different types of objects.
Controller: This is the part that controls the robot’s movements. The controller is usually a computer programmed with instructions on how to move the robot arm and gripper.
Vision system: Some pick-and-place robots have a vision system that allows them to see the objects they are manipulating. The vision system can be used to help the robot locate and orient objects, as well as to avoid obstacles.
Types of pick and place robots are based on design and structure
Robotic arms are the most common type of pick-and-place robot. The 5-axis robot arm is suitable for standard pick-and-place tasks, where objects are moved in one plane.
For more complex applications that involve twisting or reorienting objects before placement, 6-axis robotic arms are used.
Cartesian robots operate on multiple planes, moving along three orthogonal axes (X, Y and Z) using Cartesian coordinates. These robots can be built with different types of linear actuators and drive mechanisms, such as belt, ball or lead screw mechanisms. They typically deliver higher positioning accuracy than 6-axis robotic arms.
Delta robots are often used in situations where items need to be picked in groups and placed in specific assembly patterns or containers. Equipped with advanced vision technology, the Delta robot can distinguish between many different sizes, shapes and colors.
Most Delta robots consist of three arms operating on four axes, with heavy motors attached to the frame and light arms connected to linkage rods by joints, typically ball joints, that allow movement.
Rapid picking robots are ideal for medium to high volume applications with high-speed stock keeping units (SKUs). These robots completely automate the picking process, freeing humans to focus on more impactful tasks.
They excel at handling fast-moving items, such as promotional accessories or batteries, and can receive up to 300 SKUs per hour from pools of up to 8 SKUs.
Collaborative robots work with humans by leading them to choose locations and guiding them through each task. These robots optimize routes in real time, ensuring efficient work and keeping associates on track. By improving workflow efficiency, collaborative robots enable associates to work more efficiently.
