Design of bonding system for PCB repairs
Burian, Jaroslav ; Skácel, Josef (referee) ; Otáhal, Alexandr (advisor)
The goal of this thesis is to design a device for PCB repairing, mainly for conductive traces and soldering pads. The design focuses on mechanical construction, control unit and controling of the whole device, which is semiautomatic. A great deal of emphasis is placed on the simplicity and versality of the construction. The teoretic part of this thesis is addressed to the printed circuit board and its repairs. There are presented existing devices for repairing of those defects in the second part. The next part is focused on the design itself in terms of mechanical construction and choosing electrical components. There is described controlling of these components. Part of making mechanical components follows. Last but not least, firmware, which controls whole machine is described there. Finally, the machine was tested in the repair process of the solder pad on the printed circuit board.

Feasibility study of aluminium parts manufacturing at Alfa company
Honzálek, Petr ; Strejček, Jan (referee) ; Kubík, Roman (advisor)
This thesis is dedicated to a study of manufacturing of aluminum parts at Alfa company. A complete analysis of the company's main product which are roller doors for commercial vehicles is elaborated. The thesis is based on a existing operation of the company and tries to find the optimal solution for the future. The result is the definition of a new solution and determination it’s operating costs, economic impacts and suggestions for improvement. Key words roller door, aluminum profiles, slat, roller shutter, manufacturing of aluminum parts.

Autonomous vehicle for a material flow
Ryza, Vojtěch ; Pokorný, Přemysl (referee) ; Kašpárek, Jaroslav (advisor)
The focus of this bachelor thesis is a construction plan of autonomous truck for transporting EU pallets, which has a specified load weight. The concept is based on critical searches of similar autonomous trucks. Design is created in program SolidWorks 2019 and it is based on my calculations. The truck has prefabricated aluminium construction. Another device in the form of a roller track is offered on the back of the trolley.
