  • Patent number: 4691419
    Abstract: A turret is rotatably secured to a housing adapted to be secured to a robot wrist having a reference orientation and axis. The turret has a plurality of interchangeable lead processing devices which are selectively aligned to the reference orientation and axis. When so aligned a lead processing device is engaged with a selected component and operated to cut and bend the lead of that component. A second component's lead may be processed by the same or a different lead processing device secured to the turret. The latter device is aligned to the reference orientation and axis prior to processing the second component's lead. The robot is programmed to align the reference axis and the corresponding processing device to the selected component whose lead is to be processed.

  • Patent number: 4685067
    Abstract: An apparatus is provided for controlling the execution of functions associated with the automatic operation of a manipulator. While traditional function execution has been associated with arrival of a workpoint at or proximate to a predetermined point, the present invention provides for plural function execution between predetermined points. Two alternative embodiments are provided: a first embodiment controls a single output interface type and is unrelated to functions associated with predetermined points; a second embodiment provides multiple executions of any function normally associated with a predetermined point. Spacing between function executions associated with either embodiment is controlled as a function of distance specified by the operator. To produce a desired spacing, feedrate reduction is automatically effected in the event a programmed feedrate is incompatible with a specified function execution interval.

  • Patent number: 4664588
    Abstract: An exchange system is provided for connecting a remote, manipulable element, such as a robot arm tool gripper, to a central control source, such as a robot arm and its associated programmable control. An upper exchange unit attaches to the robot arm and receives control signals which pass through the body of the upper unit to a matable lower exchange unit. A plurality of lower exchange units are provided, each attached to an individual tool gripper and relaying control signals to the gripper. The mating upper and lower exchange units provide for serial connection of the robot arm to any desired one of an array of tool grippers and for communication of control signals through the mated units to each tool gripper without the need for separate control umbilicals between each tool gripper and the control signal source.

  • Patent number: 4650388
    Abstract: A device for the disconnectable coupling of a support toggle joint of a gripper to the end of a slave arm of a remote manipulator. The arm and toggle joint each have a case in which are located means for transmitting movements to the gripper. The coupling device comprises at least two latches pivotably mounted on one of the cases and which are able to occupy a coupling position in which they bear against pins fixed to the other case. This couples the toggle joint to the end of the arm and the latches can also occupy a position in which they are disengaged from the pins in order to disconnect the toggle joint. The retractable locking means normally immobilizes the latches with respect to the case supporting them when the latches occupy the coupling position. The invention also provides a disconnection support for the coupling device.

  • Patent number: 4605569
    Abstract: A method and apparatus for performing repetitive cycles of panel coating operations using a programmable manipulator including a manipulator arm movable along a plurality of axes. The apparatus comprises a hand unit carried on the manipulator arm. The hand unit is movable so as to bring the brush held by it into resilient contact with an area of the panel to be coated. A coating material is injected into the brush at a predetermined rate while the brush is held in resilient sliding contact with the panel and while the manipulator arm moves about the panel to coat a preselected area of the panel. After the preselected area of the panel has been coated, the manipulator arm is moved to move the brush out of contact with the panel. Between coating cycles, the manipulator arm moves the brush into a storage chamber where it is treated to prevent the coating material from caking on the coating brush.

  • Patent number: 4595419
    Abstract: An ultrasonic decontamination robot removes radioactive contamination from the internal surface of the inlet and outlet headers, divider plate, tube sheet, and lower portions of tubes of a nuclear power plant steam generator. A programmable microprocessor controller guides the movement of a robotic arm mounted in the header manway. An ultrasonic transducer having a solvent delivery subsystem through which ultrasonic action is achieved is moved by the arm over the surfaces. A solvent recovery suction tube is positioned within the header to remove solvent therefrom while avoiding interference with the main robotic arm. The solvent composition, temperature, pressure, viscosity, and purity are controlled to optimize the ultrasonic scrubbing action. The ultrasonic transducer is controlled at a power density, frequency, and on-off mode cycle such as to optimize scrubbing action within the range of transducer-to-surface distance and solvent layer thickness selected for the particular conditions encountered.

  • Patent number: 4542794
    Abstract: The alignment of the drill stem and bit of a rock drill rig is corrected when the force of drilling and the feeding power on the drilling machine of the rig has resulted in a change in the direction of the drill stem because of deformation of the articulated and extensible drill boom of the rig and of its pivotally supported drill support on the drill boom. The drill rig is of the type that includes elements for measuring boom lengths and articulation angles, servos for controlling such lengths and angles and a control unit which is connected to the measuring elements and servos for adjusting the drill stem and bit. The various articulation angles which are required to compensate for deformations of the drill boom and drill support are determined as if the drill boom and support were in an unloaded condition, on the basis of measured values of the boom lengths and articulation angles which have been registered in the control unit in an unloaded condition.

  • Patent number: 4523100
    Abstract: An improvement to computer control robot arm assemblies having a work head on the free end thereof for allowing the work head to be positioned and held within closer tolerance limits to a desired coordinate position. The work head is attached to the robot arm by a vernier control assembly allowing vernier movement in the X, Y, and Z directions. A moveable support member is provided on the robot arm adjacent the work head. A detector is mounted to the work head for sensing a light beam. A collimated light beam is passed through a point associated with the desired coordinate position under computer control. The work head is positioned within first tolerance limits by the robot arm under computer control. The logic of the computer then contacts the work piece with the support member to hold the free end of the robot arm in position. Under closed-loop computer control, the vernier drives are used to position the detector at a point where the work piece is in the desired coordinate position.

    Abstract: An apparatus and method for installing and removing a tool on a chuck connected to a robot arm. The chuck has a mandrel with two parallel flat sides and two protruding flanges. The tool has a tool coupling member which is supported and held against rotation by a support plate. The tool coupling member is cylindrical and has two lugs spaced apart to allow the flat sides of the mandrel to pass, but to lock over the flanges of the mandrel when the mandrel is rotated relative to the tool coupling member. A cam follower on the chuck follows a guide slot in the support plate to cause the mandrel to rotate relative to the tool coupling member. The cam follower also causes a key on the chuck to mate or disengage a key slot on the tool coupling member.
