US Patent:

46002286, Jul 15, 1986

Filed:

May 31, 1984

Appl. No.:

6/615628

Inventors:

Robert R. Tarbuck - Ardmore PA

Assignee:

Sperry Corporation - New York NY

International Classification:

B66C 102

US Classification:

294 641

Abstract:

A lockable compliant end effector apparatus is useful with a robotic arm for the automated assembly of electronic equipment. The end effector includes a main body portion having first and second ends. A socket is formed in the first end. A first fluid passageway connects the socket with the second end of the main body portion. A member is mounted for multi-directional movement in the socket. The member is retainable in a stationary position relative to the socket and has a second fluid passageway formed therethrough. The second passageway has a first end adjacent the first passageway and a second end adjacent the first end of the main body. A sealing member is connected to the mounted member adjacent the second end of the second passageway. The end effector retains an electronic component in original orientation from a pickup point to an insertion point.

Appl. No.:

6/686121

Assignee:

Sperry Corporation - New York NY

International Classification:

H05K 330

US Classification:

295648

Abstract:

An apparatus for maintaining electronic component pin alignment includes a support member having an adjacent lead shear, a stationary nest, a printed circuit board and a component feeder. A component in the component feeder includes a chip having a plurality of leads. The leads have a first end connected to the chip and a second free end. A movable lead guide engages the first end of the leads. A robot is mounted adjacent the support member for picking up the component from the component feeder, inserting the component into the stationary nest moving the component relative to the stationary nest for moving the lead guide from the first end of the leads toward the second free end of the leads, moving the component from the stationary nest to the shear for shearing the second free end of the leads, and moving the component from the shear to the printed circuit board and urging the leads into corresponding holes formed in the printed circuit board. The stationary nest includes a planar member having an elongated slot formed therein. The elongated slot has an open end, two side walls and an end wall.

Appl. No.:

6/611232

Inventors:

Robert R. Tarbuck - Ardmore PA

Assignee:

Sperry Corporation - New York NY

International Classification:

G01B 525

US Classification:

414730

Abstract:

The problem of re-establishment of initial precision registration of end-effectors used in automatic robotic assembly following failed insertion attempts is avoided due to a positive registration compliant apparatus having a support member including a bearing mount spaced apart from a shaped seat. A holder for holding and mounting electronic components is movably mounted on the support member and extends through the bearing mount. The holder has a portion correspondingly shaped for mating engagement with the shaped seat. The holder is resiliently urged into engagement with the seat. A rotation limiter is provided for limiting rotation of the holder relative to the support.

Appl. No.:

6/636935

Inventors:

Robert R. Tarbuck - Ardmore PA

Assignee:

Sperry Corporation - New York NY

International Classification:

B21F 1100

US Classification:

83196

Abstract:

During the assembly of electronic components on circuit boards, the problems of ductile smear cusps produced on wire ends by traditional scissor-type shearing are addressed by a spiral orbital shear apparatus. This apparatus includes a first fixed plate having an array of apertures and a second plate also having the array of apertures. The first and second plates have abutting surfaces. A first eccentric drive member is connected to rotate at a first rate in a first direction. A second eccentric drive member is connected to the second plate and rotates with the first eccentric drive member. The second drive member is also rotated at a second rate in the first direction independently of the rotation of the first drive member.
