Abstract

Abstract A new robotic system is provided in which the robo­tic tool is mounted for movement on a gantry above the work piece (50) upon which the work is to be performed. The tool is supported on two carriages (71,72) each of which is movable with respect to each other and with respect to the gantry so that the tool has the capacity to move through five degrees of freedom and permit a more accurate response to a sensing sys­tem which determines the position of the work piece relative to a master and then moves the tool to a working position in substantial operational compliance with the master position.

For use in a robotic assembly system, means for moving a tool mount through five axes, said means comprising: first motor means operably connected to said tool mount to rotate said mount about a first axis; second motor means operably connected to said tool mount to rotate said mount about a second axis normal to said first axis; third motor means for moving said tool mount along a third axis normal to said first and second axes. a first movable carriage, said first, second means and third motor means and said tool mount being carried thereon; a second movable carriage, said first carriage being carried on said second carriage and movable relative thereto; means for moving said first carriage relative to said second carriage along a third axis inclined to said first and second axes; second carriage support means for supporting said second carriage, and second carriage motor means operably connected to said second carriage to move said second carriage along a fifth axis, said fifth axis being inclined to each of said remaining axes.
Claim 2
Dependent Claim 175 words
For use in a robotic assembly system, means for moving a tool mount through five axes, said means comprising: first motor means operably connected to said tool mount to rotate said mount about a first axis; second motor means operably connected to said tool mount to rotate said mount about a second axis normal to said first axis; third motor means for moving said tool mount along a third axis normal to said first and second axes. a first movable carriage, said first, second means and third motor means and said tool mount being carried thereon; a second movable carriage, said first carriage being carried on said second carriage and movable relative thereto; means for moving said first carriage relative to said second carriage along a third axis inclined to said first and second axes; second carriage support means for supporting said second carriage, and second carriage motor means operably connected to said second carriage to move said second carriage along a fifth axis, said fifth axis being inclined to each of said remaining axes.
Claim 3
Dependent Claim 51 words
Means for moving a tool mount as claimed in Claim l wherein said means for moving said first carriage relative to said second carriage comprises a fourth motor means mounted on said first carriage, said motor means being operatively connected to a ball screw drive extending parallel to said third axis.
Claim 4
Dependent Claim 68 words
Means for moving a tool mount as claimed in Claim l wherein said first and second motor means are mounted on a moveable platform carried by said first carriage and said third motor means is mounted on said first carriage, and ball screw drive means operably connecting said third motor means and said moveable platform to move said platform in response to actuation of said third motor means.
Claim 5
Dependent Claim 39 words
Means for moving a tool as claimed in Claim l wherein said second movable carriage has a pair of opposite ends and is mounted on an elevated frame above a work piece upon which work is to be performed.
Claim 6
Dependent Claim 85 words
Means for moving a tool mount as claimed in Claim 4 wherein said elevated frame includes a pair of rigid parallel members, a pair of ball screws mounted one on each of said parallel members, a pair of motor means one adjacent each end of said second movable carriage, and a pair of ball nuts being operably connected between an adjacent one of said motor means and said ball screws to move said carriage along said screws in response to actuation of said motor means.
Claim 7
Dependent Claim 25 words
Means for moving a tool mount as claimed in Claim l wherein said second movable carriage carries at least one of said first movable carriages.
Claim 8
Dependent Claim 40 words
Means for moving a tool mount as claimed in Claim l wherein said second movable carriage carries a plurality of said first movable carriages each of said first movable car­riages being independent of each of said remaining first mov­able carriages.
Claim 9
Dependent Claim 93 words
Means for moving a tool mount as claimed in Claim l including a first and second axis movement assembly compris­ing a first shaft driven by said first motor means and worm gear means connecting said first shaft to said tool mount to drive said tool mount about an axis normal to said first shaft; and a second elongate cylindrical member having a main axis surrounding said first shaft and operably connected to said second motor means and said tool mount to rotate said tool mount about the main axis of said cylindrical member.
Claim 10
Dependent Claim 51 words
Means for moving a tool mount as claimed in Claim 8 wherein siad first and second asix assembly is mounted on a platform, said platform being movably connected to said first carriage and means for moving said platform relative to said first carriage along said main axis of said cylindrical member.
Claim 11
Dependent Claim 30 words
l0. Means for moving a tool mount as claimed in Claim 9 wherein said means for moving said platform includes said third motor means and a ball nut and screw.
Claim 12
Dependent Claim 152 words
For use in a robotic work system a work station for effecting work on a work piece said station comprising: a substantially rectangular frame extending through a substantially horizontal plane, a plurality of vertical posts supporting said frame above said work piece; a first carriage and a second carriage, said first carriage being mounted on said second carriage and movable relative thereto, said second carriage being mounted on said frame and being movable within said frame along the plane thereof; means for moving said first carriage through a further plane and means for moving said second carriage; a tool mounted on said first carriage, and means for moving said tool through three axes other than said first two referred axes; sensing means for determining the position of the work piece relative to a master position and means for moving said tools into a position in substantially operational com­pliance with said master position.
Claim 13
Dependent Claim 152 words
For use in a robotic work system a work station for effecting work on a work piece said station comprising: a substantially rectangular frame extending through a substantially horizontal plane, a plurality of vertical posts supporting said frame above said work piece; a first carriage and a second carriage, said first carriage being mounted on said second carriage and movable relative thereto, said second carriage being mounted on said frame and being movable within said frame along the plane thereof; means for moving said first carriage through a further plane and means for moving said second carriage; a tool mounted on said first carriage, and means for moving said tool through three axes other than said first two referred axes; sensing means for determining the position of the work piece relative to a master position and means for moving said tools into a position in substantially operational com­pliance with said master position.
Claim 14
Dependent Claim 37 words
