DESIGN OF ASSEMBLY ROBOTIZED WORKPLACE

Abstract

Urgency of the research. Replacing manual assembly with robotic workplaces increases the productivity and quality of assembly. Operator at the robotic workplace is necessary to control of the operation processes and adding components to the tanks and removing the finished parts from the appropriate box. This allows the operator to be used parallel for other activities within the production line. The cost of building a robotic workplace is relatively low compared to the rising cost of human labor. This creates a precondition for maintaining the competitiveness of the company. Target setting. The aim was to design a functional assembly robotic workplace using an affordable SCARA robot from the Dobot company. The designed robotic assembly workplace, after implementation made, should increase assembly productivity. Actual scientific researches and issues analysis. Increasing productivity without the use of automated or robotic systems is currently not possible. This leads to the spread of robotic applications even in the assembly of relatively simple parts, which are produced in several modifications. Uninvestigated parts of general matters defining. Improving the quality of assembly production with the using of robotic workplaces is required not only in the company that carries out assembly, but especially from customers of manufactured parts. It leads to reduced in the proportion of human labor to a minimum. The research objective. The aim was to design such a robotic workplace that would make it possible to relieve a person from monotonous work. Another goal was to increase the quality of pressing two parts and, above all, to increase labor productivity by at least 10%. At the same time, to ensure a minimum participation of the operator at the robotic workplace, so that he can be used for other activities within the assembly line. The statement of basic materials. The spread of affordable industrial robots with an open architecture has an increasing tendency in larger as well as smaller operations. This leads to the creation of small robotic cells, which can be relatively easily rebuilt according to current needs in the workplace.The article describes the design of a robotic assembly workplace using a SCARA robot. The workplace is designed for the as-sembly of two parts and while part is the same for all three final products. The types of connections differ only in their length in three dimensions. A vibrating hopper was used at the workplace for feeding components A. A special feeder was designed for the feeding of components B, enabling the feeding of all three lengths of component B. An automatic pressing station was designed for the assembly of components. The operator of the facility checks the activity of the workplace at regular intervals. It is only necessary to refill the components in the hopper twice per shift. Conclusions. In this work shows the solution to an important technical problem. The functional of assembly robotic work- place using an affordable SCARA robot from the Dobot company were designed. The designed workplace allows pressing 3 types of assemblies, which differ from each other only by the total length of one component. The designed robotic workplace made it possible to increase productivity by 12% and reduce the presence of the operator to the minimum possible level.
