三菱电机公司成功地研制出高精度检测焊接线焊缝坡口形状的电弧焊接用机器人的视觉传感系统。这一系统借助半导体激光器和光位置传感器的组合,能以0.2毫米的分辨率检测出靠近焊枪约20毫米处焊接线的焊缝坡口形状,适用于迄今为止难以进行的0.2～2毫米的薄板焊接。 Mitsubishi Electric has successfully developed a vision sensing system for high precision arc welding robots that detect the shape of the weld line groove. Using a combination of a semiconductor laser and a light position sensor, this system detects the shape of the weld bevel at a weld line of about 20 mm near the torch at a resolution of 0.2 mm and is suitable for hitherto difficult sheet metal welding of 0.2 to 2 mm .
