Measurement device for testing printed circuit board assemblies coming off the production line
Nejc Friškovec, Manja Obreza, Sebastijan Seme, Klemen Sredenšek, 2022, original scientific article

Abstract: The paper presents an efficient way to evaluate and determine the quality of an assembled printed circuit board coming off the production line. A printed circuit board assembly consists of electronic devices soldered to the printed circuit board, which provides the electrical connections. After assembling the printed circuit board, a function test needs to be performed to guarantee the quality of the product. Usually, the assembly lines are equipped with cameras that detect inaccuracies such as missing components. This level of quality assurance is sometimes not enough, and we need to add another degree of precaution. In addition to camera inspections, electronic measurements must be conducted. The process needs to be automated to provide repeatability and speed. The paper evaluates such a device and presents its advantages, disadvantages, and complexity. The device includes an electrical part that performs the measurements, a mechanical part that consists of a housing and a mounting nest, and a program that supervises the process.
Keywords: electrical measurement, printed circuit board, testing device, automation, intelligent measuring system

Vodenje asinhronskega stroja s pretvornikom Siemens SINAMICS G120 : diplomsko delo
Žiga Romih, 2023, undergraduate thesis

Abstract: V diplomskem delu je predstavljeno vodenje asinhronskega stroja s pretvornikom Siemens SINAMICS G120. Najprej sta predstavljeni uporabljena strojna in programska oprema, s pomočjo katerih smo izvedli eksperimentalno analizo. Podrobneje je predstavljen del programskega okolja Siemens Totally Integrated Automation Portal (TIA Portal), ki uporabnikom omogoča nastavljanje pogonskega sklopa. V okviru okolja TIA Portal so predstavljeni postopki za izvedbo vodenja z metodo U/f in za izvedbo vektorskega vodenja, pri čemer je poudarek na avtomatizirani nastavitvi parametrov pretvornika. Predstavljeni rezultati eksperimentalne analize zajemajo primerjavo med odzivi pogonskega sklopa v primeru različnih načinov vodenja, ki jih pretvornik omogoča. Na koncu so podani še napotki za ročno prilagoditev parametrov regulatorja hitrosti za doseganje želene dinamike pogona v primeru vektorskega vodenja.
Keywords: Asinhronski stroj, Siemens Totally Integrated Automation Portal, SINAMICS G120, vektorsko vodenje, vodenje U/f.

Planning and construction of the lifting and towing device of the autonomous mobile robot MiR 100 for the delivery of transport trolleys in intralogistics
Tone Lerher, Aleš Belšak, Rok Skerbiš, Jure Tumpej, Žiga Volavšek, Domen Stamenov, Marko Motaln, 2022, published scientific conference contribution

Abstract: Intralogistics is a very important area in warehousing and production for managing the flow of materials and informational flow. In recent years, automation and especially robotisation have had a major impact on throughput performance in intralogistics. Especially important is the transport of materials and products based on automated guided vehicles (AGVs) and autonomous mobile robots (AMRs) with different top modules, such as the lifting and towing device. In this paper, planning and construction of the lifting and towing device of the autonomous mobile robot MiR 100 for the delivery of transport trolleys in intralogistics is presented. Using the engineering design methods, a new design of the lifting and towing device has been proposed and evaluated.
Keywords: intralogistics, material handling systems, automation and robotisation, planning and construction, lifting and towing mechanism, simulation and animation

The Internet of Things Communication Protocol for Devices with Low Memory Footprint
Sašo Vinkovič, Milan Ojsteršek, original scientific article

Abstract: This paper describes a new communication protocol named XMC which is designed for the transmission of messages between an embedded device and a remote system. A new markup language called XMDD has also been developed and is used to describe the functional profile of the embedded device. The main advantage of the XMC communication protocol is its flexibility and independence from the device type. It is suitable for communication with devices that have a curtailed amount of working memory (a few kB) and limited computing power, i.e. 8-bit or 16-bit microcontrollers. Messaging between the embedded device and the remote systems is done without any interference with the basic source code of the embedded device, thus allowing access to all functionalities and features of the connectable embedded device and is based on the functionality dictionary and built-in features of an embedded device. It also maintains a low production price for the embedded device and from the programming point of view provides a transparent and flexible upgrade of the hardware and software without any redundancy input.

OPC-driven data exchange between MATLAB and PLC-controlled system
Stojan Peršin, Boris Tovornik, Nenad Muškinja, 2003, original scientific article

Abstract: Many manufacturing, and mechatronics systems, are controlled by PLCs and SCADAsystems. These systems provide very limited possibilities for research, optimisation, testing and simulation. The main advantage of this proposed solution, which uses OPC, is an integration of the numerical, computational and graphical strengths of MATLAB with the robustness of industrial systems. The experimental setup, the processing of the data and the results are presented with particular emphasis on student use in a laboratory environment but the techniques employed in the experiments will likely to be seen by the students in their subsequent employment after completion of their college careers.

Relational database as a cogitative part of an intelligent manufacturing system
Igor Drstvenšek, Mirko Ficko, Jože Balič, 2004, original scientific article

Abstract: An intelligent manufacturing system is intended to produce one or more subjects that it is designed for in an optimal way. This means that it has to find a proper production process to produce the subject in an optimal way. The manufacturing system can be called "intelligent" when it is able to find applicable optimisation criteria upon its past experiences thus improving its performance in future. Therefore, an intelligent manufacturing system needs capabilities to store data and make decisions upon them. Such a "brain" can be established by a proper design of a technological database and its database management system (DBMS). Examining all constitutive parameters of a work operation a model of a production process organization can be made, which can serve as a basis for a suitable database design. In addition, an application programme that will check the existence and availability of work operations in the database has to be added to the DBMS. What remains are some optimisation criteria upon which we will choose an operation among suitable and available work operations. This task is fulfilled by a genetic algorithm optimisation technique that would consider work operations' data as parameters of optimisation and on this basis search the optimal one out of the set of available operation.

A model of data flow in lower CIM levels
Igor Drstvenšek, Ivo Pahole, Jože Balič, 2004, original scientific article

Abstract: After years of work in fields of computer-integrated manufacturing (CIM), flexible manufacturing systems (FMS), and evolutionary optimisation techniques, several models of production automation were developed in our laboratories. The last model pools the discoveries that proved their effectiveness in the past models. It is based on the idea of five levels CIM hierarchy where the technological database (TDB) represents a backbone of the system. Further on the idea of work operation determination by an analyse of the production system is taken out of a model for FMS control system, and finally the approach to the optimisation of production is supported by the results of evolutionary based techniques such as genetic algorithms and genetic programming.

Jure Poteko, 2011, undergraduate thesis

Abstract: V diplomi je prikazano projektirano pnevmatsko krmilje, ki bo vodeno preko krmilnika Allen Bradley. Stroj je namenjen za proizvodnjo avtoplaščev visokih zmogljivosti – hitrostni razred H in V ter W, velikosti od 15" do 21". Uporabljene komponente morajo biti po specifikacijah naročnika, in sicer od proizvajalcev FESTO ali PARKER, oz. drugih v primeru, da prej omenjena ne ponujata potrebnih komponent. Pri izbiri ustreznih komponent pa je poleg specifikacije uporabnika potrebno upoštevati tudi konstrukcijske omejitve. Krmilje bo projektirano in simulirano v programu Automation Studio 5.7.
