The master's thesis presents a set of planning activities for several assembly units that were part of the final design of a workstation for the assembly of electronic assemblies intended for installation in a car. Initially, based on the analysis of the product specifications and the client's requirements, we defined the entire assembly process, which was divided into individual assembly operations. We predicted the number of working movements, their lengths and the appropriate components for their execution, on the basis of which we calculated the time of operations and the assembly time. Due to the complexity of the assembly system as a whole, the design of the assembly units was limited to the choice of the rotary table drive, as well as the detailed design of the mounting nest, the press assembly unit and the manipulation unit. Our basis was to create a workstation floor plan. Depending on the application requirements, we selected the type of rotary table drive. We then worked out a detailed design of the mounting nest. When designing the press assembly unit, we selected a suitable press and performed an FEM analysis of the frame. We created a morphological matrix on the basis of which we chose the appropriate concept of the manipulation unit. Suitable components were determined and the rotary gripper unit was calculated. The calculated times of operations and assembly time were compared with the measured times on a real assembly system and the functionality of the system was checked.
