“…However, torque data from joints of robot were utilized in a force-position hybrid method, which was not proper for industrial robots without joint torque data. Baksys and Baskutiene 15 presented a method with the dynamic model of the vibratory assembly system. An electro-magnetic vibrator and elastic element were designed in the vibration excitation structure.…”

As there are increasing demands for efficiency and quality in airframe assembly, automation integration is required to replace manual operation. This paper presents a design of a robotic riveting cell for wedge part riveting, which is used on the trailing edge of airfoil. To complete the continuous riveting in a row of rivets at the trailing edge, a robotic riveting cell is designed to realize a set of process actions including rivet feeding/injection/cutting and press riveting. Based on the visual compensation of the hole position, a forceless feedback spiral track rivet injection compensation method is proposed. The stress feedback-based riveting process control method is introduced after rivet injection and cutting. The proposed approach is applied to the robotic riveting cell and the rivet injector works stably. No indentation has been detected using the force-controlled riveting method. The prototype can achieve the riveting task well on the wedge part. The proposed design and approach can be applied on both wedge parts and flat parts. This will give a new way to solve the automation integration problem in airframe assembly. A robotic riveting cell is designed to realize a set of process actions. A forceless feedback spiral track rivet injection compensation method is proposed. The stress feedback-based riveting process control method is employed after rivet injection and cutting.

“…This type of asymmetry is usually applied to various industrial vibrational transportation applications [14][15][16]. Baksys and Baskutiene [17] investigated the characteristics of the motion of the compliant body subjected to kinematic excitations along the direction of the joining axis. Moreover, Baksys and Puodziuniene [18] have investigated the body motion from a static state to dynamic equilibrium by using vibrational non-impact displacement of an exited-based body on an inclined plane, where different asymmetries such as power asymmetry and kinematical asymmetry are combined.…”

A transportation system requires an asymmetry to achieve objects’ motion on an oscillating surface. Transportation methods based on vibrational techniques usually employ different types of asymmetries, such as temporal (time) asymmetry, kinematic asymmetry, wave asymmetry or power asymmetry. However, transporting an object on an inclined angle requires a relatively high net frictional force over each period of vibrational cycles due to the gravitational potential energy exerted on the object. This paper investigates the transportation of an object upward on an inclined plane that harmonically oscillates in its longitudinal direction. The novelty of this research is attributed to the upward motion of the object on the inclined plane, which is achieved by creating an additional asymmetry of the system through dry friction dynamic manipulations. For this reason, periodic dynamic dry friction manipulations have been employed to create the asymmetry of frictional conditions, resulting in a net frictional force that outweighs the gravitational force. A mathematical model has been developed using the Lagrange method, which describes the moving object’s motion. Moreover, the theoretical findings and results confirmed that the object’s velocity and direction can be controlled by dynamic dry friction manipulations. To demonstrate the technical feasibility of the proposed method, an experimental investigation was carried out where the results demonstrated that the control parameters significantly influence the characteristics of the directional motion of the moving object. This transportation method is beneficial for various modern industries engaged in transportation and manipulation tasks with objects spanning a broad range of sizes, including those operating at small scales for applications in lab-on-a-chip technology, micro-assembly lines, micro-feeder systems and other delicate component manipulation systems. The presented research advances the classical theories of vibrational transportation on inclined surfaces.

“…However, an analytical model was not built. In [7,8], the influence on the assembly process of oscillations along the conjugation axis and along the inclined axis was studied. In work [3], the assembly of parts was studied when the installed part rotates with respect to the non-inertial reference frame and the base part rotates with respect to the inertial reference frame.…”

The prospects for the introduction of assembly automation in the industry are largely determined by the reliability of the assembly process. One of the reasons for reducing its reliability is parts jamming. In order to increase the technological reliability of the assembly process, various physical and technical effects are applied. The article presents the results of an experimental study using the rotational movement effect and low-frequency vibrations of the base part in order to reduce assembly efforts and the probability of part jamming.
