Abstract

Abstract A manipulator (10) including a compliant suction means (215 and 220) and two pairs of independently operable jaws (55, 60) precisely and delicately locates a workpiece (300) for delivery thereof to a location remote from that at which the piece is picked up.

Claims Analysis

Total Claims: 18
Claim 1
Independent Claim 162 words
A manipulator for collecting parts from a first location for transport to, and deposit precisely at a remote, second location, said manipulator being characterized by: a frame; a suction means carried by said frame and including a nozzle for engaging said parts and restraining said parts from movement in a first direction; a first pair of jaws which open and close in a second direction, said first pair of jaws being carried by said frame and operable by an actuator, for locating said parts in said second direction; and a second pair of jaws which open and close in a third direction, said second pair of jaws being carried by said frame and operable by another actuator independently from said first pair of jaws for locating said parts in said third direction, whereby said jaws are capable of locating parts of diverse shape in said second and third directions with controllable force and minimal sliding contact between said part and said jaws.
Claim 2
Dependent Claim 162 words
A manipulator for collecting parts from a first location for transport to, and deposit precisely at a remote, second location, said manipulator being characterized by: a frame; a suction means carried by said frame and including a nozzle for engaging said parts and restraining said parts from movement in a first direction; a first pair of jaws which open and close in a second direction, said first pair of jaws being carried by said frame and operable by an actuator, for locating said parts in said second direction; and a second pair of jaws which open and close in a third direction, said second pair of jaws being carried by said frame and operable by another actuator independently from said first pair of jaws for locating said parts in said third direction, whereby said jaws are capable of locating parts of diverse shape in said second and third directions with controllable force and minimal sliding contact between said part and said jaws.
Claim 3
Dependent Claim 16 words
The manipulator of claim 1 characterized by said first, second and third directions being mutually orthogonal.
Claim 4
Dependent Claim 11 words
The manipulator of claim 1 characterized by said actuators being pneumatic.
Claim 5
Dependent Claim 24 words
The manipulator of claim 1 characterized by a spring interposed between said suction means and said frame, said spring rendering said suction means compliant.
Claim 6
Dependent Claim 47 words
The manipulator of claim 1 characterized by said first and second pairs of jaws being pivotally mounted on said frame and operated by first and second cams, respectively, said first and second cams being mounted on said frame and individually powered by first and second motors, respectively.
Claim 7
Dependent Claim 14 words
The manipulator of claim 5 characterized by said first and second motors being pneumatic.
Claim 8
Dependent Claim 39 words
The manipulator of claim 5 characterized by each jaw of said first and second jaw pairs being provided thereon with an integral cam follower engageable by a respective one of said first and second cams for closing said jaws.
Claim 9
Dependent Claim 33 words
The manipulator of claim 7 characterized by said jaws being biased open, the closing force on said jaws being modulatable by the regulation of the power input to said cams by said motors.
Claim 10
Dependent Claim 18 words
The manipulator of claim 8 characterized by said jaws being biased open by springs mounted on said frame.
Claim 11
Dependent Claim 16 words
The manipulator of claim 5 characterized by said first and second cams having generally conically-shaped surfaces.
Claim 12
Dependent Claim 39 words
The manipulator of claim 5 characterized by said frame including an elongate guide extending interiorly of said frame in said first direction and by said first and second cams being coaxially mounted on said guide for reciprocal movement therealong.
Claim 13
Dependent Claim 29 words
The manipulator of claim 11 characterized by said guide being hollow and by said suction means comprising a tube received within said guide for reciprocal movement with respect thereto.
Claim 14
Independent Claim 160 words
A method of transporting a part by a manipulator from a first, general location to a second, specific location at which said part is deposited, said method being characterized by the steps of: picking up said part with a suction means by engagement therewith and restraining said part in a first direction by said suction means; locating said part in a second direction with respect to said manipulator while maintaining the engagement of said part with said compliant suction means; subsequently locating said part in a third direction with respect to said manipulator while maintaining the engagement of said part with said compliant suction means; releasing said part from said compliant suction means to relieve any bending stresses therein while said part remains restrained by said gripping jaws; subsequently re-engaging said part with said compliant suction means for delivery thereby to said second location; and releasing said part from said compliant suction means at said second location for deposit thereat.
Claim 15
Independent Claim 160 words
A method of transporting a part by a manipulator from a first, general location to a second, specific location at which said part is deposited, said method being characterized by the steps of: picking up said part with a suction means by engagement therewith and restraining said part in a first direction by said suction means; locating said part in a second direction with respect to said manipulator while maintaining the engagement of said part with said compliant suction means; subsequently locating said part in a third direction with respect to said manipulator while maintaining the engagement of said part with said compliant suction means; releasing said part from said compliant suction means to relieve any bending stresses therein while said part remains restrained by said gripping jaws; subsequently re-engaging said part with said compliant suction means for delivery thereby to said second location; and releasing said part from said compliant suction means at said second location for deposit thereat.
Claim 16
Dependent Claim 22 words
The method of claim 13 characterized by said part being located in said second and third directions by independently operable gripping jaws.
Claim 17
Dependent Claim 36 words
The method of claim 14 characterized by said suction means lowering said part below said jaws for subsequent release of said part at said second location by said suction means with minimal interference from said jaws.
Claim 18
Dependent Claim 16 words
The method of claim 13 characterized by said first, second and third directions being mutually orthogonal.
