Abstract

A compliant end effector includes a robot mounting bracket and a component support member. The component support member includes a side surface and a top surface. A component clamping system includes a first clamp member operable to move toward the side surface of the component support member and a second clamp member operable to move toward the top surface of the component support member. A controller is operatively connected to the clamping system. The controller is configured to engage the first and second clamp members as the component gripping and manipulating system is in a set position and release the first clamp member and the second clamp member allowing a portion of a component held by the component clamping system to move with one or more degrees of freedom when the component gripping and manipulating system is moving to the set position.

First claim

What is claimed is:

1. A compliant end effector for a component gripping and manipulating system comprising:
a robot mounting bracket mountable to a robot manipulating arm;
a component support member connected to the robot manipulating arm, the component support member configured to be inserted into a component and configured to support the component with clearance such that movement of the component relative to the component support member is allowed, the component support member including a side surface and a top surface;
a component clamping system including a first clamp member operable to move toward the side surface of the component support member and a second clamp member operable to move toward the top surface of the component support member, the first clamp member configured to press the component against the side surface and the second clamp member configured to press the component against the top surface to fix the component relative to the component support member; and
a controller operatively connected to the clamping system, the controller configured to engage the first and second clamp members as the component gripping and manipulating system is in a set position and release the first clamp member and the second clamp member allowing a portion of the component held by the component clamping system to move with one or more degrees of freedom, when the component gripping and manipulating system is moving to the set position.

2. The compliant end effector according to claim 1 , wherein the component support member includes a first component support member having a first side surface and a first top surface and a second component support member having a second side surface and a second top surface, wherein the first clamp member is operable to move toward the first side surface.

3. The compliant end effector according to claim 1 , wherein the component support member includes a first support element fixedly mounted relative to the robot mounting bracket and a second support element engageable with a supported component.

4. The compliant end effector according to claim 3 , wherein the second support element is shiftable relative to the first support element.

5. The compliant end effector according to claim 4 , wherein the second support element includes the side surface and the top surface.

6. The compliant end effector according to claim 5 , wherein the first clamp member urges the supported component against the side surface of the second support element.

7. The compliant end effector according to claim 5 , wherein the second clamp member urges the supported component against the top surface of the second support element.

8. The compliant end effector according to claim 1 , wherein the second clamp member comprises a rotatable arm connected to a rotary actuator.

9. The compliant end effector according to claim 1 , wherein the first clamp member comprises a piston coupled to a linear actuator.

10. The compliant end effector according to claim 1 , further comprising a component ground system supported by the component support, the component ground system providing an electrical ground to a supported component.

11. A component gripping and manipulating system comprising:
a first robot having a first manipulating arm supporting a first component end effector fixedly connected to a first end of a component;
a second robot having a second manipulating arm supporting a second component end effector compliantly connected to a second end of the component, the second component end effector comprising:
a robot mounting bracket connected to the second robot;
a component support member connected to the robot manipulating arm, the component support member configured to be inserted into a component and configured to support the component with clearance such that movement of the component relative to the component support member is allowed, the component support member including a side surface and a top surface;
a component clamping system including a first clamp member operable to move toward the side surface of the component support member and a second clamp member operable to move toward the top surface of the component support member, the first clamp member configured to press the component against the side surface and the second clamp member configured to press the component against the top surface to fix the component relative to the component support member; and
a controller operatively connected to the clamping system, the controller configured to engage the first and second clamp members as the component gripping and manipulating system is in a set position and release the first clamp member and the second clamp member allowing a portion of the component held by the component clamping system to move with one or more degrees of freedom, when the component gripping and manipulating system is moving to the set position.

12. The component gripping and manipulating system according to claim 11 , wherein the component support member includes a first component support member having a first side surface and a first top surface and a second component support member having a second side surface and a second top surface, wherein the first clamp member is operable to move toward the first side surface.

13. The component gripping and manipulating system according to claim 11 , wherein the component support member includes a first support element fixedly mounted relative to the robot mounting bracket and a second support element engageable with a supported component.

14. The component gripping and manipulating system according to claim 13 , wherein the second support element is shiftable relative to the first support element.

15. The component gripping and manipulating system according to claim 14 , wherein the second support element includes the side surface and the top surface.

16. The component gripping and manipulating system according to claim 15 , wherein the first clamp member urges the supported component against the side surface of the second support element.

17. The component gripping and manipulating system according to claim 15 , wherein the second clamp member urges the supported component against the top surface of the second support element.

18. The component gripping and manipulating system according to claim 11 , wherein the second clamp member comprises a rotatable arm connected to a rotary actuator.

19. The component gripping and manipulating system according to claim 11 , wherein the first clamp member comprises a piston coupled to a linear actuator.

20. The component gripping and manipulating system according to claim 11 , further comprising a component ground system supported by the component support, the component ground system providing an electrical ground to a supported component.
