Title: Automatic welding device of the MIG/MAG typeApplicant: Serimax (FR); Destouches Denis (FR)Patent number: WO2007066013Publication date: 14 June 2007
The present invention relates to an automatic welding device of the MIG/ MAG type, consisting of at least one carriage carrying at least one welding head comprising at least one torch, guiding a consumable wire electrode along a joint plane between pipes to be welded, which brings the current to the tip of the wire electrode in order to generate an electric arc and to melt the filler metal. The invention consists in the fact that the welding head therefore has a welding torch intended to be centred with respect to the joint plane in order to ensure the penetration pass and also carries at least two other welding torches, called following torches, which are positioned, respectively, one after the other, after the first welding torch, called the central torch, and are offset, respectively, on either side of the central torch in order to make lateral passes. Application to the welding of metal pipes in order to form pipelines.
Title: Laser welding method and laser welding arrangementApplicant: Rippl Peter (DE)Patent number: US2006249486Publication date: 9 November 2006
A machining system and unit, especially a welding cell, is provided for use for the machining of workpieces, especially body parts of vehicles. The machining system has one or more machining stations with robots and at least one rotation or turning station, which has at least two work stations for carrying out different operations simultaneously. The turning station has at least two multiaxially movable turning units arranged next to one another with the gripping tools. The working areas intersect each other at the work stations.
Title: Automotive vehicle framing system<Applicant: Valiant Corp. (CA)Patent number: EP1764291Publication date: 21 March 2007
A vehicle framing system for framing an automotive vehicle body from a plurality of separate body components wherein the body components each include a reference surface. The system includes an assembly station having spaced-apart frame members positioned so that, when a vehicle carrier supporting the vehicle body components is positioned at the assembly station, the frame members extend along opposite sides of the vehicle carrier. At least two docking stations are secured to each frame member at predetermined locations. A robot mounts its associated tool arm with a docking station. At least one set of reference block and framing clamp is secured to each tool arm and these framing clamps maintain the reference surfaces of the vehicle body components against the reference blocks to hold the vehicle components at a predetermined position relative to each other. After each robot positions each associated tool arm with the docking station, the robot disengages from the tool arm and then welds the body components together by a welding gun carried by the robots.
Title: Calibration method for improving the accuracy of a robotic measuring system with joint configuration dependent performanceApplicant: Sun Yunquan (US); Tang Qing (US)Patent number: US2007050090Publication date: 1 March 2007
Industrial robots have been widely used in industrial applications such as welding, and assembly. However, the application of the robots to precision manufacture is limited by their accuracy. As a highly non-linear system, the positioning accuracy of a robot varies with the configuration of the joints or the angular positions as well as translational positions of its joints. This results in a mechanical system of a low accuracy, but very high repeatability. This invention is about an innovative approach that will improve the accuracy of a robotic measuring system to the level of the repeatability of the robot. It is a calibration method for improving the accuracy of a robotic measuring system with joint configuration dependent performance. With such an increased measuring accuracy, the robotic measuring system can be used in many industrial applications requiring a robotic measuring system of high accuracy. One such an application is the automated measurement of the orientations and positions of many holes located on the surface of a part.
Title: Robotic welding system and method for welding projection weld nutsApplicant: Honda Motor Co Ltd (JP)Patent number: US7250585Publication date: 31 July 2007
A system and method for welding projection weld nuts to a work piece. The system and method of the present invention generally makes use of a fixtured work piece having one or more projection weld nuts associated therewith. A resistance welding robot is used to weld the projection weld nuts to the work piece. The welding robot typically has weld electrodes therewith, through which electric welding current is passed to the projection weld nut(s) and the work piece. A first and second contacting electrode is used to transfer electric current from the welding robot electrodes to the projection weld nut(s) and work piece.
