Understand the four core structures of welding robots in one article

The four core structures of welding are controller, transmission mechanism, and prime mover. Next, Wuxi Jinhongying, a professional welding robot manufacturer, will introduce them to you in detail.

1. Controller: The controller of the welding robot is a special system responsible for motion control, welding parameters, robot and external functions. The controller is usually composed of a central processing unit (CPU), various input/output interface cards and memory. The controller decomposes the welding task into a series of robot motion and welding operation instructions, and sends these instructions to the robot's transmission mechanism and prime mover to complete.

2. Transmission mechanism: The transmission mechanism of the welding robot is the core mechanism responsible for the movement of the robot, which is usually composed of various motion devices, transmission parts and structures. The motion devices include linear modules and rotary modules, the transmission parts include transmission elements such as gears, sprockets, belts, etc., and the mechanical structure consists of various moving parts of the welding robot. They work together to enable the robot to achieve various movements and postures in three-dimensional space.

3. Sensors: Sensors of welding robots are an important part of control and safety assurance. Sensors strongly support decision-making and control during the welding process. They mainly include visual sensors, tactile sensors and position sensors. They can monitor parameters such as part geometry, weld quality, workpiece position and posture, determine the position and size of welding points, and ensure the safety of robot movement.

4. Motive mechanism: The motive mechanism of the welding robot is the power source for realizing various movements of the robot. Usually, various motors are used, such as DC motors, AC synchronous motors, stepper motors, etc. They convert electrical energy into mechanical energy through the transmission mechanism and drive various parts of the robot to realize various movements.
