Publication number: 20210370531Abstract: A pin and socket that form a connector to pass high current from a robotic device to a tool. The pin includes a separate non-conductive cap section and a conductive contact section along the length. The socket includes a body with an interior space and a body opening that leads into the interior space. A toroidal spring is positioned in the interior space of the body and includes an annular shape with a toroidal spring opening that aligns with the body opening. When fully inserted, the contact section of the pin contacts against the toroidal spring and the cap section is positioned in the interior space away from the toroidal spring.Type: ApplicationFiled: May 28, 2020Publication date: December 2, 2021Inventors: Dustin Christopher Simons, William G.

Patent number: 11097390Abstract: A robotic tool changer ensures inherently safe decoupling operation by only providing pneumatic fluid to a decouple port of a pneumatic coupling mechanism in the case that the tool changer is seated on, and properly aligned with, a tool stand. Pneumatic fluid to decouple the pneumatic coupling mechanism is routed from an air source to the tool stand. A pass-through in the tool stand returns the pneumatic fluid to a pneumatic path in the tool changer leading to a decouple port of the pneumatic coupling mechanism. Hence, the tool changer must be seated on the tool stand for the decouple port to receive pneumatic fluid to operate. Furthermore, a safety coupling is interposed on the pneumatic path between the tool stand and the decouple port. The safety coupling requires the tool changer to be seated on, and properly aligned with, the tool stand to effect the flow of pneumatic fluid—otherwise, the pneumatic fluid is bled to the atmosphere.Type: GrantFiled: August 26, 2019Date of Patent: August 24, 2021Assignee: ATI Industrial Automation, Inc.Inventors: William G. Berrocal, Mack Earl Manning, John M. Winterroth

Patent number: 10404010Abstract: A modular approach to an electrical power and/or signal passing utility module is presented. A universal receptacle is fixedly disposed in bores in both of first and second signal connector blocks. A threaded socket member and a nonconductive guide bushing are installed, as needed, in receptacles in the first block, and a threaded pin member is installed in corresponding receptacles in the second block. The nonconductive guide bushing insulates the sockets, and guides pin posts into the socket as the two blocks abut. A compliant member such as an o-ring provides compliance of the socket and pin assemblies in the signal connector blocks, making the assemblies self-aligning. The socket and pin assemblies are field-replaceable by use of a simple tool.Type: GrantFiled: May 1, 2017Date of Patent: September 3, 2019Assignee: ATI INDUSTRIAL AUTOMATION, INC.Inventors: William G.

Patent number: 9731392Abstract: Alignment modules attached to a robotic tool changer assist spatial orientation and alignment of a robot arm relative to a robotic tool for location training. A three-axis spatial orientation sensor is first attached to an alignment module affixed to a tool unit. The sensor is “zeroed,” or calibrated to the spatial orientation of the tool unit. The sensor is transferred to a corresponding surface of an alignment module affixed to a master unit. The orientation of the robot arm is adjusted to eliminate sensor error signals indicating deviations from the zeroed orientation of the tool unit. An optical signal, such as a cross line laser beam, is then projected between the alignment modules. The x- and y-axis position of the robot arm is adjusted to align the optical signal with alignment markings. When the master and tool units are aligned, the robot arm is advanced in the z-axis direction until the master unit abuts the tool unit.Type: GrantFiled: August 5, 2014Date of Patent: August 15, 2017Assignee: ATI Industrial Automation, Inc.Inventors: Alfred Atef Takla, William G.

Publication number: 20160052146Abstract: A robotic tool changer ensures inherently safe operation by separating power sources for the “couple” and “decouple” operations of its coupling mechanism. The power for the decouple operation is available only when an attached robotic tool is safely disposed in its tool stand. Once the robotic tool leaves the tool stand, there is no power supplied to the coupling mechanism of the robotic tool changer to decouple the robotic tool from a robot arm. Accordingly, it is impossible for the robotic tool to inadvertently become disengaged from the robot arm—even if software were to erroneously assert a DECOUPLE signal, or otherwise initiate a decouple operation. Furthermore, since the design is inherently safe, neither interlock circuits, the redundancy of such circuits, nor the extensive and complex monitoring circuits necessary to ensure their proper operation, are necessary.Type: ApplicationFiled: June 25, 2015Publication date: February 25, 2016Inventors: William G.

Patent number: 7964998Abstract: A linearly actuated switch assembly is adjustably disposed in a housing stem bore of a robotic crash protector device. An actuation plate is disposed over the central bore of the contact surface. As the piston moves toward the housing base in response to a crash force or torque applied to the actuator, the actuation plate moves in an axial direction, and contacts and actuates the switch. The actuation plate is biased towards the contact surface by an actuation spring disposed between the actuation plate and a spring plate that is rigidly affixed to the housing stem. This arrangement allows the actuation plate to “float” with respect to the fixed spring plate. In particular, the actuation plate may assume the orientation of the piston, which may be canted from its default orientation—normal to the device central axis—by uneven application of force by the actuator.Type: GrantFiled: January 9, 2009Date of Patent: June 21, 2011Assignee: ATI Industrial Automation, Inc.Inventors: William G.

Patent number: 6640394Abstract: A tamper-proof tie includes a head and an attached strap. The head includes a strap accepting channel and a blind cavity. The strap accepting channel includes a strap entry end and a strap exit end. The blind cavity includes an open end. The head includes a flexible locking member comprising first and second ends which are fixed in place within the head. The strap includes an anti-tampering device which comprises a finger and a projection. In use, the strap is inserted into the strap accepting channel so the tie forms a closed loop. As the strap is inserted into the head, the locking member engages the anti-tampering device to prevent withdrawal of the strap from the head. With the tie formed into a closed loop, the anti-tampering device substantially encloses the entry end and the exit end of the strap accepting channel and the open end of the blind cavity.Type: GrantFiled: April 11, 2002Date of Patent: November 4, 2003Assignee: Avery Dennison CorporationInventors: William G.
