Pick and place robot

Pick and place robots are automated machines that move components with speed and precision in assembly and packaging lines.

About this subject

Pick and place robots are a type of industrial automation designed to pick an item from one location and move it to another. They are widely used in printed circuit board assembly, where they place tiny electronic components with micrometer precision. Typical speeds can reach hundreds of movements per minute, depending on the model and application.

These systems usually combine a robotic arm with a computer vision system. The camera identifies the position and orientation of the component, while the robot adjusts its movement to place it correctly. Many pick and place robots use electric or pneumatic actuators, and most advanced models operate in clean environments to avoid contaminating sensitive parts.

The origin of pick and place robots dates back to the 1970s, with the development of industrial robots dedicated to electronics assembly. Companies like Universal Instruments and Fuji were pioneers. Today, the technology has evolved to include collaborative models that work alongside humans without safety cages. The semiconductor and consumer goods industries are the largest users, but sectors such as food and pharmaceuticals also adopt these robots for fast, hygienic packaging.

Frequently Asked Questions

What is the typical accuracy of a pick and place robot?

High-performance models can achieve accuracy of ±0.01 mm, sufficient for mounting resistors and microchips.

In which industries are pick and place robots most common?

They are prevalent in electronics (PCB assembly), but also used in food packaging, pharmaceuticals, and automotive for smaller parts.

How does computer vision work in these robots?

A camera captures the component image, software identifies its position and orientation, and the robot adjusts path to pick and place precisely on target.
