Abstract
Es wird eine Ultraschallschweissanlage, eine Bauteilaufnahme fuer eine Ultraschallschweissanlage und ein Verfahren vorgestellt, mit denen Sonotrode und Bauteilaufnahme in der fuer den Schweissvorgang erforderlichen relativen Position zueinander waehrend jedes einzelnen Schweissprozesses positioniert werden koennen.

 

DE 10301423 A UPAB: 20040826 NOVELTY - The ultrasonic welding assembly has a sonotrode (4) on a stack (1). A holder (7) is opposite the stack with a component holder to take the component (6) for welding by the sonotrode. A system positions the stack and/or sonotrode in a direct relation to the component holder, during the separate welding processes. DETAILED DESCRIPTION - The ultrasonic welding assembly has a sonotrode (4) on a stack (1). A holder (7) is opposite the stack with a component holder to take the component (6) for welding by the sonotrode. A system positions the stack and/or sonotrode in a direct relation to the component holder, during the separate welding processes, with at least one guide pin (8) at the stack and/or sonotrode and at least one guide drilling (10) at the holder. The sonotrode extends from the stack, with its converter and booster, supported at a carrier. 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.
