  • Rotary transformer
    Patent number: 7911307
    Abstract: The invention relates to a variable transformer comprising at least one primary winding and at least one secondary winding which can be rotated in relation thereto. The primary winding and the secondary winding are subdivided into at least two winding sections. The winding sections interlock in a comb-like manner and the flow of current of directly opposite winding sections is directed in the respective opposite direction.

  • Method for positioning a welding robot tool
    Patent number: 7738996
    Abstract: A method for joining together at least two sheets with a tool controlled by an industrial robot and including a first arm and a second arm that are mutually movable in relation to each other. An actual position of the sheets is detected by bringing one of the arms to sense the actual position of the sheets. The distance between an ideal position and the actual position is calculated and the actual position of the tool is moved the calculated distance, whereafter the sheets are joined together.

  • Industrial Robot
    Publication number: 20070273319
    Abstract: A power supply system for an industrial robot. The power supply includes a transmitting part including a first coil and a first converter for producing an alternating magnetic field from the first coil. The power supply also includes a receiving part including a second coil for providing an alternating current by induction from the alternating magnetic field and a second converter for producing from the alternating current a direct current for providing power to a tool carried by the robot.

  • Apparatus and procedure for attachment of a tool on a tool attachment plate on an industrial robot
    Publication number: 20050055135
    Abstract: The invention consists of an industrial robot comprising a control system and a manipulator provided with a tool. The manipulator is provided with a number of moveable arms relative to one another, and an attachment of a tool. The attachment of a tool includes a carrying organ, which carries the tool while assembling. A locking ring locks the tool to the manipulator after centring of the tool. A method of doing the same is also included.
