I.Working Principles of Laser Weld Seam Tracking Sensors
Laser Emission:The sensor emits a laser beam directed onto the workpiece surface.
Surface Scanning:The sensor may use the laser beam to scan the workpiece surface,acquiring topological information to understand the position and shape of the weld seam.
Reflection Detection:The sensor receives signals reflected back by the laser beam.By analyzing the characteristics of the reflected signal,the sensor can determine the position and shape of the weld seam.
Real-time Feedback:The sensor may provide real-time feedback,enabling the control system to make adjustments to welding robots or automated welding equipment based on calculated weld seam position and shape information,facilitating automatic seam tracking and welding.
II.Advantages of Laser Weld Seam Tracking Sensors
High Precision:Laser weld seam tracking sensors possess high-precision measurement capabilities,achieving micrometer or even nanometer-level measurement accuracy,suitable for measuring weld seams of various complex shapes.
Fast Scanning:Laser beam scanning is rapid,enabling quick scanning and measurement,thereby improving work efficiency.
Non-contact Measurement:Laser weld seam tracking sensors employ non-contact measurement methods,causing no damage to the tested object and having no impact on the welding process.
Strong Adaptability:These sensors can adapt to various materials and colors of the tested objects,demonstrating strong adaptability.
High Reliability:Laser weld seam tracking sensors exhibit high reliability and stability,allowing for continuous operation over extended periods with low maintenance costs.
III.Applications of Laser Weld Seam Tracking Sensors
