Strictly speaking, the welding robot weld tracking and positioning system consists of two parts: before welding, the weld positioning function is tested to see whether the gap is suitable and accurately reaches the welding joint point; Real-time monitoring of welds and monitoring of product deformation during welding.
Welding stalking: It refers to the installation of optical sensors in front of the welding orientation for data collection, or the collection of welding parameters through the power supply, and then transmitted to the welding robot, and various adaptive ambiguous control algorithms are carried out to calibrate the track of the welding robot or special aircraft, complete adaptive control, and reach real-time welding seam tracking.
Weld positioning: refers to the process of locating the weld by using one or more searches, through the way of moving the welding robot or modifying the machine program before welding to accurately locate the joint to be welded.
Weld tracking is to detect the deviation of the weld in real time during welding, adjust the welding path and welding parameters, and ensure the reliability of welding quality.
Due to the existence of processing errors in the workpiece (size difference between workpieces, preparation of grooves, etc.), clamping accuracy, and thermal deformation during welding, welding robots working in the teach-and-reproduce method often have a decrease in welding quality due to deviations between the weld seam and the teach-in track. Therefore, weld stalking is an important element to ensure the welding quality of welding robots.
The sensor is a key part of the weld active tracking system. Its function is to detect the orientation and shape information of the weld and convert it into a signal, and the control system processes the signal, and controls the active adjustment mechanism to adjust the orientation of the welding gun according to the detection results, and then completes the active tracking of the weld.
The use of laser welding seam tracking sensor with welding robot is equivalent to equipping the robot with eyes, which can correctly guide the robot to weld positioning.
