Abstract本发明涉及一种激光拼焊焊缝背面几何形貌检测方法及其实现装置,方法包括:利用一字线型激光器投射在背面焊缝表面产生激光条纹;通过传感单元采集获取包括激光条纹的焊缝表面灰度图像,并将所采集的图像传送给图像处理单元;图像处理单元对采集到的焊缝图像进行处理,获得各形貌参数值;判别焊缝质量,完成焊缝背面几何形貌检测;装置包括:传感单元采集激光拼焊焊缝图像,传输至图像处理单元;图像处理单元对采集到的焊缝图像进行处理;参数设置及控制单元对各参数进行设置,并分别与传感单元、图像处理单元、上位机进行通讯连接。本发明避免了焊接过程中焊缝背面吸附的烟尘、焊接飞溅、板材划痕等干扰因素产生的检测误差,极大地提高了检测精度。
Other AbstractThe invention relates to a method for detecting the geometric shape of the back of a tailor-welding weld and an implementing device thereof. The method comprises the following steps that: a linear laser is used for projecting laser on the back of a tailor-welding weld so as to generate a plurality of laser streaks on the surface of the tailor-welding weld a sensing unit acquires and obtains a weld surface gray level image including the laser streaks and transmits the acquired image to an image processing unit the image processing unit processes the acquired weld image to obtain all shape parameters and the weld quality is judged and thus the detection on the geometric shape of the back of the weld is finished. The implementing device of the method comprises a sensing unit, an image processing unit and a parameter setting and control unit, wherein the sensing unit is used for acquiring the image of a tailor-welding weld and transmitting the image to the image processing unit, the image processing unit is used for processing the acquired weld image, the parameter setting and control unit is used for setting all parameters and is respectively in communication with the sensing unit, the image processing unit and an upper computer. According to the invention, detection error caused by interference factors such as dust on the back of the weld, welding splatter, board scratch and the like in the welding process can be avoided, and the detection accuracy is improved greatly.
