摘要:
A multi-axis electric spraying robot adapted for use in a hazardous environment includes a base having a first pressurized compartment and an arm assembly having a second pressurized compartment in which compartments electric motors are respectively located. The arm assembly is supported for movement on the base at one end thereof. The arm assembly includes a wrist adapted for connecting the opposite end of the arm assembly with a spraying tool. One electric motor is provided to drive each axis. The compartments are pressurized to prevent flammable gases or vapors from entering the first and second compartments during operation of the robot.

A robot-laser system having a minimum number of mirrors for reflecting a laser beam from a fixed laser beam source to a desired location wherein the mirrors are mounted within the hollow, servo-controlled parts of the robot to move therewith. Only a single mirror is mounted within is associated controlled part to reflect the laser beam as it travels between adjacent controlled parts. The robot has a number of degrees of freedom constituted by two orthogonally related linear movements along intersecting longitudinal axes and two orthogonally related rotary joints having intersecting pivotal axes. Preferably, two of the mirrors are mounted so that the laser beam strikes and is reflected from both points of axes intersection within two of the controlled parts. In one of disclosed embodiments a mirror mounted in the base of the robot reflects the laser beam from the source to the other mirrors.

A method and system for transfer of fluids, such as paint, using a fluid canister carried by a transfer device, such as a robot, instead of having paint lines connected to a delivery device, such as a spray gun, carried by the robot. A novel mechanism for initially docking and then filling the canister from a fluid outlet of a pressurized source of fluid without straining the robot is provided. Also, a novel mechanism for cleaning the canister between canister fillings is provided so that paint colors can be changed without loss of productive robot time. In one embodiment, the canister is integrated with the robot. Also, a novel, non-contact sensor is provided for providing a signal to allow the metering of the paint entering or/and discharged from the canister.

Method and system are provided wherein a process robot moves the door of a vehicle to an open position, performs a robotically controlled process within the vehicle and then moves the door back to a closed position. A separate, two-axis programmable arm holds the door in the open position. In particular, the process robot has attached thereto a tool extension whereby the process robot goes in through a window opening of the door of the vehicle, executes a door open path where the door contacts the inner panel of the door and opens the door over a magnetic holder positioned on the two-axis programmable arm below the bottom of the door. The magnet is of sufficient magnetic strength to accurately hold the door at the programmed holding position of the two-axis arm. The process robot then performs a production operation (i.e. painting, priming, sealing, etc.) within the vehicle. The process robot then inserts the tool extension into the window slot of the door and closes the door without touching the processed surfaces of the vehicle.

Method and system are provided for cleaning a paint supply line and changing paint colors by inserting and propelling a termination piston or slug having an outer diameter which forms a sliding fit within the supply line to wipe paint off the interior walls of the supply line. Preferably, the supply line is elastic and the termination piston squeegees the paint off the interior walls. In order to more fully clean the supply line prior to changing paint colors, a predetermined amount of cleaning fluid such as a solvent is injected into the supply line behind the termination piston from a common passage of a manifold. A leading piston or slug is then inserted immediately ahead of a new paint color in the supply line. The pistons may be disposable or may be reused by recirculating them by means of shuttle assemblies and a return line. The manifold is fitted with various valves to selectively supply pressurized air, solvent and two or more paint colors to the supply line. The shuttle assemblies are also fitted with valves to shuttle the pistons between the supply and return lines. A process controller controls the timing of the valves of the manifold and the shuttle assemblies. The method and system can also be used to retrofit existing color changers in an economical yet environmentally sound fashion.

A robot-laser system having at least one mirror under active program control for reflecting a laser beam from a fixed laser beam source to a desired location. Preferably, first and second mirrors are mounted on an outer arm of the robot to move therewith and rotate relative thereto. A third mirror reflects the laser beam to the first and second mirrors. A programmable servo system automatically moves each of the mirrors relative to and in synchronization with movement of the moving parts of the robot. Each of the mirror is mounted for rotation about a pair of intersecting axes so that the laser beam strikes the point of intersection. In one of the disclosed embodiments a fourth mirror reflects the laser beam from the source to the other mirrors.

The present invention recognizes that the limiting structures to size reduction for an optical encoder were the laser diode/photo diode package and the photodetector with amplifier package(s). The invention includes removing the discrete components from the laser diode cover package and mounting the much smaller discrete components on a base framework. The photodetector with amplifier package of the invention have an altered photodetector/amplifier geometry including shortening the leads between them. This resulted in significant size reduction of the encoder, a reduction in required gain and resulting increase in bandwidth. The entire base framework is temperature cooled by disposing two thermo-electric coolers between the base framework and an adjacent heat sink. Such positioning of the two coolers between the base framework and it's adjacent heat sink stabilizes both the laser diode's and the photo detector's outputs. In addition this novel design stabilizes the entire footprint/base of the encoder from thermal effects, whatever their origin.
摘要:
A robot system including a robot, an operator control center and having a communication system connecting the robot and control center wherein an operator in the control center responds with natural movements to stimulus signals from the robot environment by issuing commands that control the robot. In one embodiment, the operator occupies a command chair with an exoskeletal arm that is secured to the "shoulder" (backrest) of the chair. The operator slides his hand into a glove of the invention attached to the end of the exoskeletal arm. He views the robot environment through a video screen and exerts control in response to views presented on the screen. The communication system sends signals to the operator glove in response to conditions at the robot site prompting the operator to take appropriate action.
