Abstract:
An automatic locating system for a vehicle crash pad, comprising:a synchronous running truck for synchronously moving with an overhead hanger that conveys a car body on an assembly line on a workplace floor; a robot unit, arranged at a side of the synchronous running truck, for supplying and locating the crash pad in the car body, the crash pad being supplied from a crash pad feed conveyor running in parallel with the synchronous running truck; first, second, third and fourth position detectors for outputting position error signals of the crash pad and the car body by detecting the crash pad and detecting holes in pillars of the car body; first and second distance detectors for outputting distance error signals for a mounting position of the crash pad by detecting mounting holes for the crash pad in the car body; a limit switch for outputting an advancing signal when the overhead hanger advances to a working position; a vehicle-type detector for outputting a vehicle-type detection signal after detecting a size of the car body; a vision controller for outputting the detected vehicle-type signal and each position error signal received from the first, second, third and fourth position detectors based on the body pillar detecting holes; and a robot controller adapted to control positioning of the robot unit, supplying and locating of the crash pad, and synchronizing of the truck and the overhead hanger on the basis of the detected vehicle-type signal received from the vision controller, a vehicle-type signal of the crash pad received from a main controller for managing the assembly line, the advancing signal of the overhead hanger received from the limit switch, and the distance error signals of the mounting position of the crash pad based on the mounting holes received from the first and second distance detectors.
