Abstract:
A robot wrist comprises a first wrist part (1) configured to be mounted to a robot arm, a second wrist part (2) rotatable in relation to the first wrist part (1) about a first axis of rotation (A 1 ), a third wrist part (3) rotatable in relation to the second wrist part (2) about a second axis of rotation (A 2 ), and a protection hose (4) extending through the robot wrist. The first axis of rotation (A 1 ) intersects with the second axis of rotation (A 2 ) within a boundary wall of the protection hose (4) in at least one position of the robot wrist. Intersection of the first and the second axes of rotation (A 1 , A 2 ) within the boundary wall of the protection hose (4) is achieved by making the second wrist part (2) compact in the longitudinal direction of the protection hose (4), and wide in the radial direction of the same. As a result the protection hose (4) is arranged in a single circular arc in a bent position of the robot wrist, which in its turn results in an improved service life of the protection hose (4).
Abstract:
The invention is a method, controller and control system for controlling a robot that is used in concert with at least one other robot to perform an operation on one or more work objects. Each robot controller checks whether a common reference value is not acceptable, and if so, provides a signal for the robot to wait before proceeding to the next task. Each robot controller also checks whether the target object is in the correct position or not; and also checks whether or not another robot has stopped. If either another robot has stopped and/or if the work object is not in the right position, the robot waits. The invention is particularly advantageous for automated painting whereby a production line may be re-started more quickly again after a stoppage or production delay.
Abstract:
The present invention relates to a system for visualizing process errors that occur in connection with processing a workpiece by means of a process tool (3) and an industrial robot (5) moving the tool along a path in relation to the workpiece during the processing. The system is configured to store information on process errors and information on where on the robot path the error occurred upon detecting the process errors and to present a visualization of the robot path (10) and the position of the stored errors (13) in relation to the robot path.
Abstract:
A method for accessing statistical analysis data on industrial devices of an industrial production line, wherein the method comprises: - integrating statistical analysis tools into the industrial devices, - generating statistical data using the integrated statistical analysis tools on the devices, - presenting the statistical analysis data on devices, resulting in access to the analyzed statistical data on the devices.
Abstract:
A method for pushing paint out of a paint line (14) in an automated painting or coating apparatus by introducing a fluid plug means into the paint line of the automated painting or coating apparatus and using a second liquid to push the fluid plug through the paint line.
Abstract:
A live handle switch in the form of a hand operated safety switch for an industrial robot or a machine is described. The live handle comprises a safety certified switch for operating a robot or other machine safely while under manual control. The live handle switch may be comprised in a portable robot controller of the TPU Teach Pendant unit type. Such a TPU may comprise control means for moving a robot in three or more degrees of freedom. In other aspects of the invention a system comprising a robot and a control unit and the live handle switch are described.
