ABSTRACT

This paper is based on a scientific research, made by the authors, with the aim to reduce the designing and execution time of a grabbing device, intended for the handling and transferring operation of a car body part. The grabbing device is designed and 3D shaped, presented in the paper, is realized by assembling typical elements of constructive types, the alignment and fixation of the handled object in the grabbing device being realised vacuum, pneumatically and mechanically. 1. Description and functionality of the designed vacuum grabbing device The constructive type of the vacuum grabbing device modular assembly presented in the first part of the paper was projected by the authors with the aim of constructive and functionality optimization for a more efficient usage in the operations of grabbing, fixing and robotic handling of a metallic structure like a auto body rooftop. The Robotic handling has as aim the grabbing and transferring the metal structure, from one technological stage of manufacturing, such as cold compressing, technological operation made in a cambering/molding section, to another manufacturing point situated at a certain distance, where the handled object enters into a new phase of technological manufacturing. This could be, for example, a department for thermo-chemical treatment, containing the stages for degreasing, cleaning-washing followed by a thermo-chemical treatment applied before the painting in electrostatic field of the handled element. As we mentioned before, it can be observed from the 3D design of the assembly, that the component elements of the vacuum grabbing device designed are standardized and modulated, and because of this it allows a substantial reduction of the designing time and the reduction of the manufacturing time of the product. For this we had at our disposal, for documentation, catalogs from different companies devoted to this fields, from which we can name the companies TUNKERS, NORGREN, FESTO. On a central aluminum extruded profile numbered 14, foreseen longitudinally with a T canal on each side, are assembled in order all the typical elements. The first components installed are the two lateral devices for grabbing with claws, their clamps claws being pneumatically operated, and having the purpose of fixing and unfixing the auto body metallic structure, on the central area. In picture 1 we can see a upper view of the vacuum grabbing device, and from this point of view we can observe the values of the linear and angular values of the mounting and associating contact, the composition, distribution and the adjustment of the main component elements by which it can be realized the centering, grabbing and fixing the auto body element, for the purpose of robotized handling.
