Six axis industrial robots have become increasingly popular in the manufacturing industry due to their versatility and efficiency. These robots are capable of performing a wide range of tasks such as welding, painting, palletizing, pick and place, and assembly. The movements performed by six axis robots are controlled by various driving methods. In this article, we will explore the commonly used driving methods for six axis industrial robots.
1. Electric Servo Motors
Electric servo motors are the most commonly used driving method for six axis industrial robots. These motors provide high accuracy and precision, which is essential for tasks such as welding and painting. Electric servo motors also provide smooth and consistent movements, which is crucial for pick and place and assembly tasks. Additionally, electric servo motors are energy efficient, which can save companies money on their energy bills.
2. Hydraulic Drives
Hydraulic drives are also commonly used for six axis industrial robots. These drives use hydraulic fluid to transmit power to the robot's joints. Hydraulic drives provide high torque, which is essential for heavy lifting and handling tasks. However, hydraulic drives are not as precise as electric servo motors, which makes them unsuitable for tasks such as welding and painting.
3. Pneumatic Drives
Pneumatic drives are another cost-effective driving method for six axis industrial robots. These drives use compressed air to power the robot's movements. Pneumatic drives provide high speed and are ideal for tasks requiring rapid movements, such as pick and place and packaging. However, pneumatic drives are not as precise as electric servo motors, which limits their use in precision tasks such as welding and painting.
4. Direct Drive
Direct drive is a driving method that eliminates the need for gears and belts. This method uses high-torque motors that are directly attached to the robot's joints. Direct drive provides high precision and accuracy, making it ideal for tasks such as welding and painting. This driving method also provides excellent repeatability, which is essential for assembly tasks. However, direct drive can be costly, which makes it less popular than other driving methods.
5. Reducer Drives
Reducer drives are a cost-effective driving method that uses gears to provide torque to the robot's joints. These drives are ideal for tasks requiring heavy lifting and handling. However, reducer drives are not as precise as electric servo motors, which limits their use in precision tasks such as welding and painting.
6. Linear Motors
Linear motors are a relatively new driving method for six axis industrial robots. These motors use a flat ribbon of magnetized metal to provide linear motion. Linear motors offer high precision and speed, making them ideal for tasks such as pick and place and assembly. However, linear motors can be costly, which limits their use in cost-sensitive applications.
Six axis industrial robots are an essential part of modern manufacturing. These robots are capable of performing a wide range of tasks due to the various driving methods available. Electric servo motors are the most commonly used driving method due to their high precision and accuracy. Hydraulic drives are ideal for heavy lifting and handling tasks, while pneumatic drives provide high speed. Direct drive offers high precision and accuracy, while reducer drives are a cost-effective option for heavy lifting and handling. Linear motors are a relatively new driving method that offers high precision and speed. Companies should choose the driving method that best suits their application and budget.
