<p>PURPOSE:To permit the correct assembly by installing a plurality of visual sensors, assembly units, and a controller onto a detection and assembly station, thus permitting the correct position adjustment for parts, in a part assembling device in assembly lines, etc. CONSTITUTION:Four TV cameras I-IV are positioned at the prescribed positions on the floor of a detection station 1 in an assembly line, and the standard point positions at four corner parts on the undersurface of a car body A which is sent is detected, and signals S1-S4 are transmitted to a control device 50, and converted to the prescribed coordinate values. When the coordinate value is compared with that of the standard point and the deflection from a tolerance value is detected, the camera in disorder is detected and demounted, and the coordinate value of the normal camera is supplied into an assembly station. Position is detected by the TV cameras I'-IV' similarly at an assembly station 2, and the detected coordinate value is compared with the coordinate value supplied from the detection station 1, and the correct standard point is obtained, and the correct part installation position is calculated from the position, and assembly units 10 and 20 are operated so that each assembly position for the assembled bodies B and C coincides.</p> |
