An Analysis of the Components of a Welding Robot
2021-02-10
Welding robots are modern, automated devices that integrate knowledge from multiple fields, including computer science, electronics, sensors, and artificial intelligence. A welding robot primarily consists of two major components: the robot body and automated welding equipment. Welding robots facilitate the stabilization and improvement of welded products, enable 24-hour continuous production, significantly boost production efficiency, and replace human workers in hazardous environments where long-term work is required. Welding robots used directly for welding include those for arc welding, resistance welding, and gas welding. The editorial team at Shanghai ChaiFu Robotics Co., Ltd. will now take you through an analysis of the components of a welding robot!
I. Components of a Welding Robot
1. Executive Components: These are the mechanical structures that transmit force or torque and perform specific movements to complete welding tasks. They include the robot's body, arm, wrist, and end-effector.
2. Control System: This consists of electronic and electrical components, as well as computer systems, responsible for directing the mechanical structure to perform welding operations between specified positions according to predetermined programs and required trajectories.
3. Power Source and Transmission System: This comprises the components and devices that supply and transmit mechanical energy to the actuators; power sources are typically electric or hydraulic.
4. Process Support System: This primarily includes the robot’s welding power source, wire feeder, and gas supply system.
II. Selection of Degrees of Freedom for Welding Robots
The arm and wrist of a welding robot constitute its basic motion components. Any robot arm design features three degrees of freedom to ensure that the end effector can reach any point within its working range. The three degrees of freedom of the wrist involve rotational movements around the three mutually perpendicular spatial coordinate axes—X, Y, and Z—commonly referred to as roll, pitch, and yaw.
When purchasing and using welding robots, customers should consider the following aspects:
1: The production of welded parts is characterized by high variety and small batch sizes.
2: The structural dimensions of the welded parts are primarily small to medium-sized, and the material and thickness of the parts are suitable for spot welding or gas shielded welding.
3: The dimensional accuracy and assembly precision of the workpieces to be welded must meet the process requirements for robotic welding.
4: Equipment used in conjunction with the welding robot—such as automated welding equipment and welding positioners—should be able to coordinate movements with the robot to ensure a synchronized production rhythm.
Shanghai ChaiFu Robotics' 4- to 6-axis industrial robots are widely used in arc welding, spot welding, plasma cutting, stamping, painting, grinding, machine tool loading and unloading, palletizing, material handling, and educational applications, creating value for our customers.
