AI Technical Summary

Technical Problem

Traditional laser welding equipment is difficult to adapt to complex and varied workpiece surfaces, resulting in unstable welding quality. In particular, when dealing with uneven or concave workpieces, defects such as pores and cracks are prone to occur, which limits its application range and affects product quality and reliability.

Method used

An automatic focusing device based on dual-beam laser welding is adopted. The angle and position of the laser head are adjusted by two first motors and a first connecting plate. Combined with the real-time monitoring of the workpiece surface condition by sensors, automatic focusing is achieved to ensure that the laser head maintains the optimal welding posture.

Benefits of technology

It improves the precision and quality of welding, ensures high-precision and high-quality welding results, adapts to complex surface conditions, reduces welding defects, and enhances the overall performance of the product.
