<p>Process and device for the automatic assembly and working of sub-assemblies consisting of several individual pieces, held by a work piece carrier (4) on a transfer line with resettable working stations (3). The sub-assemblies are first removed by the work piece carrier at the working station (3) and brought together in the assembly position, where they are held and worked on, primarily through spot welding, or final welding. In order to carry out these different tasks, and for maximum adaptibility of the working station the latter is equipped with several work piece carriers (22, 23) which have at least three axes of movement. The work piece carriers (22, 23) are all arranged on a parallel plane above and below the work piece carrier (4) so as to operate freely. The work piece carriers (22, 23) carry individual tools which they can change automatically from fixed or movable tool magazines (31, 33, 34). To suit the needs of various tasks, as well as when there is a change in the type of sub-assembly, new, mosaic-like combinations can be obtained using freely programmable adjustment drives, allowing for independent movement of each individual work piece carrier (22, 23).</p> |
