Abstract
Es werden eine Ultraschallschweissanlage, eine Bauteilaufnahme einer Ultraschallschweissanlage und ein Verfahren zur Erfassung der Relativposition von Sonotrode und Bauteilaufnahme vorgestellt. Vorzugsweise koennen die Vorrichtungen durch eine an einem die Sonotrode lagernden Stack angebrachte Laserdiode und einen auf der Aufnahme angebrachten Lichtdetektor verwirklicht werden.
DE 10301433 A UPAB: 20040915 NOVELTY - The ultrasonic welding assembly (1) has a sonotrode (5) mounted at a stack (2), and a facing holder (7) to take the workpiece holder (16) with the workpiece component (6) for welding. The relative positions of the sonotrode and the holder are registered during the welding at regular or uneven intervals, together with a system to position them according to their detected positions. DETAILED DESCRIPTION - The ultrasonic welding assembly (1) has a sonotrode (5) mounted at a stack (2), and a facing holder (7) to take the workpiece holder (16) with the workpiece component (6) for welding. The relative positions of the sonotrode and the holder are registered during the welding at regular or uneven intervals, together with a system to position them according to their detected positions to correct their alignments. The position setting can be mechanical, electrical and/or electromechanical, with the position correction triggered manually or automatically. A LED or laser diode (8) at the stack and/or sonotrode forms a light spot on the holder by a vertical light beam (15), and a position detector (9) registers the position of the light spot. USE - The ultrasonic welding assembly is especially for the production of plastics housings for electrical and electronic equipment and particularly sensors, to protect the electrical/electronic components, with housing dimensions of 10 multiply 10 multiply 30 mm to 100 multiply 40 multiply 80 mm. ADVANTAGE - The assembly gives a rapid setting-up, with an accurate and reliable guide action on the sonotrode in relation to the workpiece during the welding process.
