焊接部分显像方法和用于该方法的装置
摘要：
本发明提供了一种用于对一对在它们之间具有台阶的待焊接的焊接构件的对接焊接部分进行观察的方法和装置，其中不会由于台阶而受到遮蔽区的中断。该装置包括用于对焊接部分12进行摄影的CCD摄像机13，其设置在直接位于凹槽部分11之上的垂直平面内，在凹槽部分11之上，厚度不同的焊接构件10a和10b以相对于法线14成预定的倾斜角度地对接设置，闪光灯15设于直接位于凹槽部分11上面的垂直平面内，在角度设置上，相对于以法线14作为对称轴线的CCD摄像机的对称角度设置而偏离±10°至20°，照射光从直接设置在凹槽部分11上面的闪光灯15中照射出来，从而消除了在待焊接的构件10a与配对构件10b的对接焊接部分12产生遮蔽区的可能性，因而防止了由闪光灯15照射焊接部分12的高亮度照射光的规则反射分量集中地入射到CCD摄像机13中，从而获得焊接部分12的具有适合于图像处理的亮度的图像。
摘要（英）：

A method and device for observing a butt welded part of a pair of welding members to be welded having a step therebetween are provided without being interrupted by a shadow due to the step. The device comprises a CCD camera 13 for photographing a welded part 12 is arranged inside a vertical plane immediately above a groove portion 11 at which welding members 10a and 10b differing in thickness are subjected to butt arrangement at a predetermined inclined angle from a normal line 14, a flash lamp 15 is provided inside the vertical plane immediately above the groove portion 11 in an angular arrangement deviated at +-10 DEG to 20 DEG from an angular arrangement symmetrical to the CCD camera in which the normal line 14 is given as a symmetrical axis, illumination light is irradiated from the flash lamp 15 arranged immediately above the groove portion 11, thereby eliminating a fear of generating a shadow at the butt welded part 12 of the member to be welded 10a with the counterpart 10b, thereby preventing regular reflection components of high- brightness illumination light irradiating the welded part 12 from the flash lamp 15 from being intensively made incident into the CCD camera 13 to obtain images of the welded part 12 having brightness appropriate in image processing.
