JOINT GUARANTEE SYSTEM FOR VEHICLE ASSEMBLY AND CONTROL METHOD OF THE SAME
First Claim
1. A fastening history guarantee system for a vehicle assembly line which assembles a fastening object to a vehicle body conveyed on a conveyer line with fastening members, the system comprising:
- a vehicle body sensing unit disposed on the assembly line sensing a vehicle body entering the conveyer line, and sensing the distance to the vehicle body by radiating and receiving a laser at entry and exit sides of the conveyer line;
a plurality of tool sensing units disposed at predetermined intervals along the conveyer line and sensing the position of a fastening tool;
an inertia sensor module disposed on the fastening tool and senses the angle and the displacement of the fastening tool at fastening points for the vehicle body and the fastening object;
a tool controller that supplies control signals corresponding to the fastening points and the fastening object, the types of fastening members, and fastening torque of the fastening tool; and
a main controller that obtains the position information of the vehicle body and the fastening tool, and the angle and displacement of the fastening tool through the vehicle body sensing unit, the tool sensing unit, and the inertia sensor module, wherein the main controller sets the fastening points, the types of the fastening members, and the fastening torque of the fastening tool, transmits the set values to the tool controller, and receives and stores an identification number of the vehicle body, the types of the fastening members, and the fastening torque resultant value of the fastening tool from the tool controller.
