[0005] Therefore, the cost involved in the conventional method is quite high, especially when changing the vehicle model and increasing the production volume, while the restrictive movement and group positioning of the position of the welding head creates constraints on the design of the door panel, structurally and aesthetically. Design and sales forces have counterproductive factors

Embodiment Construction
[0031] Referring to the accompanying drawings, in figure 1 Among them, 1 represents a door panel assembled using the method and device of the present invention. These panels are usually of a unique design for each vehicle model and are further divided into panels for the front and rear doors and panels for the left and right doors. Each door panel 1 comprises a plurality of components 10, 10' (for simplicity, figure 1 and 2 Only two of them are shown in ), generally comprising a housing or assembly of conventional or non-conventional shape, made of plastic and / or fibrous material. In order to be able to assemble these parts, one or more parts 10 are provided with welding locations in the shape of rods 11 integrally formed with each part 10 . The other part, indicated with 10' and which must be assembled with the first part 10, has a corresponding hole 12. In this way, among the plurality of parts forming the door panel 1, part 10 and part 10' respectively form male and fem...

A method for assembling and welding vehicle door panels is disclosed. At an initial assembly station (20) components (10, 10') of the panels are assembled and arranged on carriages (14, 15) for carrying the panels, which are profiled in a way adaptable to the shape of the panels. The carriages with the components of the panels are automatedly transported to a welding station (20') . At such station a welding head (35) , which is movable with a plurality of degrees of freedom, is automatedly positioned and orientated, and if necessary, the configuration of the welding head is automatedly changed. The carriages with the assembled and welded panels are automatedly transported to a removal station (20'') . At such station, the assembled and welded panels are removed, and the unloaded plates or carriages are automatedly returned from the removal station to the initial station. Those of the operations which are automatedly performed are coordinated in adaptable and programmable fashion according to a processing sequence which depends from the design specifications of the panels.
Description
technical field [0001] The invention relates to a system for assembling and welding automotive door panels. Background technique [0002] In the automotive industry, door panels are mounted on door frames for aesthetic, structural and safety reasons. Door panels are also used as supports for door pulls, armrests and storage pockets. Their influence on the interior design of the car body is significant. Door panels are designed in increasingly complex shapes, consisting of multiple parts made of plastic or vegetable fiber material, which are welded together during assembly using ultrasonic or vibration-generating devices. [0003] Due to the shape of the door panels and the need to ensure structural integrity, welding is a critical part of the assembly process. The main components of the door panels are currently loaded by hand into dedicated welding tables, which are equipped with multiple independently fixed axis sonotrodes with dedicated tips for performing specific wel...
