Abstract:
1. A system for assembly of a component on a body structure of a motor-vehicle comprising: a welding centre for welding or fixing the component on the body structure: a conveying line for carrying to the welding centre a succession of the body structures and for carrying out of the welding centre the body structures with the component assembled thereon: a gripping and clamping device, the gripping and clamping device including means for gripping the component to connect the component thereto, and configured to clamp the connected component on the body structure, and by the clamping, constrain the connected component on the body structure in a proper position of assembly, wherein the gripping and clamping device is configured to be supported by the body structure for conveyance together therewith by the conveying line: a first manipulator configured to bring the gripping and clamping device into a condition of connection with the component in a pick-up position, according to a predetermined mutual positioning, and for carrying the device connected to the component to a body structure that is located in a position, on the conveying line, upstream of the welding centre, for constraining the component to the body structure according to a mutual positioning whereby the component comes to occupy a proper position of assembly; a storage site designed to receive the gripping and clamping device, the first manipulator means being designed to pick up the gripping and clamping device from the storage site to bring the gripping and clamping device into connection with the component in the pick-up position; and a second manipulator means designed to pick up the device from the body structure in the welding or fixing centre or downstream thereof, after the component has been assembled thereon and to bring it back to the storage site; wherein the storage site comprises a structure that extends along the conveying line of the system, and is configured to interface, on a side upstream, with respect to a direction of advance of the body structures along the conveying line, with the first manipulator means, and, on a side downstream, with respect to the direction of advance of the body structures along the conveying line, with the second manipulator means, and further comprises means for conveying the device between the side upstream and the side downstream.
