Abstract

A workstation and method for processing a plurality of workpieces includes at least one material handling robot movable along a processing path for supporting a workpiece to be moved along the processing path. At least one station can be defined by at least one processing position adjacent the processing path for receiving workpieces to be processed when delivered and positioned by the at least one material handling robot. Interchangeable end effecters can be connected to the material handling robot for holding and supporting different configurations of workpieces. The material handling robot can disengage from the end effecter at the processing position, to allow engagement with a processing tool for performing additional processing operations on the workpiece. A flexible body workstation for assembling workpieces can use multiple robots and/or multiple fixtures for processing different workpiece configurations in any sequential order along two processing paths.

Claims

1. A workstation for processing a plurality of workpieces comprising:

at least one material handling robot movable along a processing path for supporting a workpiece to be moved along the processing path; and

at least one station defined by at least one processing position adjacent the processing path for receiving workpieces to be processed when delivered and positioned by the at least one material handling robot.

2. The workstation of claim 1, wherein the at least one material handling robot further comprises:

a first material handling robot movable along a first processing path for supporting a first workpiece to be moved along the first processing path; and

a second material handling robot movable along a second processing path for supporting a second workpiece to be moved along the second processing path.

3. The workstation of claim 2, wherein the at least one station further comprises:

a first station monument defining the processing position located between the first and second processing paths for supporting a workpiece to be processed delivered by one of either the first and second material handling robot.

4. The workstation of claim 1 further comprising:

at least one material processing robot located adjacent the processing position for processing workpieces to be processed after being delivered by the first material handling robot.

5. The workstation of claim 1 further comprising:

interchangeable end effecters connectable to the first material handling robot for holding and supporting different workpiece configurations.

6. The workstation of claim 5 further comprising:

the interchangeable end effecters for locating the workpieces to be processed with the corresponding material handling robot at the processing position.

7. The workstation of claim 5 further comprising:

the corresponding material handling robot disengageable from the end effecter at the processing position, allowing engagement with a material processing tool for performing additional processing operations on the workpiece to be processed located at the processing position.

8. The workstation of claim 5 further comprising:

the interchangeable end effecters being floor mountable by the corresponding material handling robot at the processing position.

9. The workstation of claim 5 further comprising:

a geometry fixture tool incorporated into the interchangeable end effecters for accurately positioning the workpieces to be processed with respect to the end effecter and allowing the corresponding material handling robot to accurately position the workpiece and end effecter combination at the processing position.

10. A method for processing a plurality of workpieces comprising the steps of:

supporting a workpiece to be moved along a processing path with at least one material handling robot movable along the processing path; and

receiving workpieces to be processed when delivered and positioned by the at least one material handling robot with respect to at least one station defined by at least one processing position adjacent the processing path.

11. The method of claim 10 further comprising the step of

supporting a first workpiece to be moved along a first processing path with a first material handling robot;

and

supporting a second workpiece to be moved along a second processing path with a second material handling robot movable along the second processing path.

12. The method of claim 11 further comprising the step of:

supporting a workpiece to be processed delivered by one of either the first and second material handling robots with at least one station monument located between the first and second processing paths.

13. The method of claim 11 further comprising the step of:

processing workpieces to be processed after being delivered by one of either the first and second material handling robots with at least one material processing robot located adjacent the processing position.

14. The method of claim 11 further comprising the step of:

holding and supporting different workpiece configurations with interchangeable end effecters connectable to the first and second material handling robots.

15. The method of claim 14 further comprising the step of:

locating different workpiece configurations with the interchangeable end effecters and the corresponding material handling robots at the processing position.

16. The method of claim 14 further comprising the step of:

mounting one of the interchangeable end effecters with respect to the at least one station defined by the at least one processing position with the corresponding material handling robot.

17. The method of claim 14 further comprising the step of:

disengaging the corresponding material handling robot from the end effecter at the processing position.

18. The method of claim 17 further comprising the step of:

engaging the corresponding material handling robot with a material processing tool for performing additional processing on the workpiece to be processed located at the processing position.

19. The method of claim 14 further comprising the step of:

accurately positioning the workpieces to be processed with respect to the end effecter with a geometry fixture tool incorporated into the interchangeable end effecters.

20. The method of claim 19 further comprising the step of:

accurately positioning the workpiece and end effecter combination at the processing position with the corresponding material handling robot.
