Abstract

A parts table may comprise a structure including a first surface, a base including a platform affixed to the structure, and kinematic couplers secured to the base and configured to dock with complementary kinematic couplers of an alignment structure, the alignment structure being secured to a floor of an assembly cell, the first surface including a parts interface configured to hold a plurality of parts for assembly in the assembly cell, such that each part of the plurality of parts can be picked up by a robot of the assembly cell when the parts table is docked with the alignment structure, and the parts table is movable to a new location when the kinematic couplers are undocked from the alignment structure.

First claim

What is claimed is:

1. A parts table, comprising:
a structure including a first surface;
a base including a region configured to accommodate an autonomous guided vehicle (AGV), and a platform affixed to the structure;
at least one edge of the platform includes a mechanism for engaging the AGV; and
kinematic couplers secured to the base and configured to dock with complementary kinematic couplers of an alignment structure, the alignment structure being secured to a floor of an assembly cell,
wherein the first surface includes a parts interface configured to hold a plurality of parts for assembly in the assembly cell, such that each part of the plurality of parts can be picked up by a robot of the assembly cell when the parts table is docked with the alignment structure, and wherein the parts table is movable to a new location when the kinematic couplers are undocked from the alignment structure.

2. The parts table of claim 1 , further comprising a frame coupled to the structure and to the base, the frame configured to stabilize the structure.

3. The parts table of claim 1 , wherein the base includes spaced-apart elongated members to which the kinematic couplers are secured.

4. The parts table of claim 1 , wherein the mechanism includes a latch for engaging with the AGV.

5. The parts table of claim 1 , wherein a lower surface of the platform includes a part retention device for mating with a complementary retention device on the AGV when an upper surface of the AGV is raised upward toward the platform.

6. The parts table of claim 1 , further comprising a utility coupler interface connected to the base and configured to engage with a utility system interface connected to the alignment structure, to receive any one or more of power, data communications, or pneumatics for use at the parts table.

7. The parts table of claim 1 , wherein the AGV, when engaged with the parts table, uses a detector to locate at least one docking target extending upward from a base plate of the alignment structure, the base plate connected to a floor surface, wherein the AGV enters the alignment structure between two prong members extending laterally outward from the base plate of the alignment structure, such that the two prong members form a gap for the AGV to enter, the AGV being further movably guided by a plurality of guide rollers coupled along an inner edge of each prong member to position and engage the kinematic couplers with the complementary kinematic couplers.

8. The parts table of claim 1 , further comprising:
a plurality of universal part interfaces connected to the parts interface, wherein each universal part interface of the plurality of universal part interfaces is configured to hold one of a plurality of differently-shaped parts.

9. The parts table of claim 8 , wherein each universal part interface of the plurality of universal part interfaces includes a lever configured to tilt on a first axis to a second position at which a part being held is at a different orientation.

10. The parts table of claim 1 , wherein the parts interface comprises a mating feature configured to engage with a complementary mating feature of each part of the plurality of parts.

11. The parts table of claim 10 , wherein the mating feature includes at least a pin or a ball bearing.

12. The parts table of claim 1 , wherein the parts interface comprises a compliance interface.
