International Classification:

G05B 19/04
H01L 21/67
G12B 13/00

US Classification:

700254, 41422202

Abstract:

Described herein is a method and apparatus for performing calibrations on robotic components. In one embodiment, a method for performing robotic calibrations includes moving the calibrating device across a target (e.g., a wafer chuck). Next, the method includes measuring distances between light spots from the sensors and a perimeter of the target using the sensors located on the calibrating device. Next, the method includes determining a displacement of the calibrating device relative to a center of the target. Then, the method includes determining a rotation angle of the calibrating device relative to a system of coordinates of the target. Next, the method includes calibrating a robot position of the robot based on the displacement and rotation angle of the calibrating device with respect to the target.

Abstract:

Described herein is a method and system for performing calibrations on robotic components. In one embodiment, a method for performing robotic calibrations includes manually calibrating a center of a robot blade aligned with respect to a target. The method further includes recording a first positional value of the center of the robot blade aligned with respect to a camera. The method further includes automatically determining a second positional value of the center of the robot blade aligned with respect to the camera. The method further includes automatically recalibrating the robot blade based on an offset between the second positional value and the first positional value exceeding a tolerance offset from the first positional value.

Appl. No.:

16/887140

Inventors:

- Guaynabo PR, US
Vijay K. Sakhare - Mason OH, US

International Classification:

A61B 17/115
A61B 17/068

Abstract:

An apparatus includes a body, a shaft, and a stapling head assembly. The shaft extends distally from the body. The stapling head assembly is positioned at a distal end of the shaft. The stapling head assembly includes a staple driver member and a knife member. The staple driver member is configured to drive a plurality of staples into tissue. The knife member is configured to cut through the tissue. The knife member includes a proximal end, a distal end, and a cylindrical body extending between the proximal and distal ends. The cylindrical body includes at least one coupling feature that operatively couples the knife member with the staple driver member.

International Classification:

A61B 17/115

Abstract:

An apparatus includes a body, a shaft, and a stapling head assembly. The shaft extends distally from the body and includes a coupling feature. The coupling feature includes threading or at least one barb. The stapling head assembly is configured to cut and staple tissue. The stapling head assembly is positioned at a distal end of the shaft. The stapling head assembly includes a knife member and a body member. The knife member includes a circular cutting edge configured to cut through tissue. The body member is configured to house the knife member. The body member includes a coupling feature that is configured to mechanically couple with the coupling feature of the shaft. The coupling feature of the body member includes threading or at least one barb.

International Classification:

A61B 17/115
A61B 17/11
A61B 17/072

Abstract:

An apparatus includes a body, a shaft, and a stapling head assembly. The body includes a chassis, a bracket, a coupling, and a conical coil. The bracket is configured to move relative to the chassis between first and second positions when selectively activated by a user. The bracket includes an upright member. The conical coil spring is disposed between the bracket and the coupling. The conical coil spring includes a proximal end, a distal end, a conical helical body disposed between the proximal and distal ends, and at least one dead coil disposed at the distal end of the conical coil spring that is configured to prevent the distal end of the conical coil spring from being retained between the bracket and the chassis. The shaft extends distally from the body. The stapling head assembly is positioned at a distal end of the shaft.
