AI Technical Summary
Interference between real and false laser spots in existing laser processing equipment leads to inaccurate focusing and low efficiency. Current technology cannot effectively distinguish between real and false laser spots, affecting focusing accuracy and efficiency.
By acquiring multiple real-time light spot features under working conditions, true light spots are screened out. Based on the preset mapping relationship between light spot features and positions, the real-time position of the true light spots is determined and adjusted to the preset processing position. The light spots are identified by combining multi-layer neural networks and image segmentation algorithms, and false light spot interference is eliminated.
Robust extraction and accurate feature acquisition of real light spots under complex working conditions have been achieved, improving the autofocus robustness and versatility of laser processing, and overcoming the problems of inaccurate focusing and low efficiency caused by interference from real and false light spots.
