Using RFID Technology in Collaborative Design of the Assembly Systems

Modern production conditions require the application of the concept of distributing production. This approach means coordinative production in a number of small and middle size companies. Multiplex products, consisting of a number of parts, components, and modules are assembled in one function unit in one company, but they may not be manufactured in one place. Huge factory and production complex, which existed in our country, comprised all phases of product lifecycle, from the development of a concept solution to the assembly. Technology of product manufacturing, resource logistics, quality control, product testing and verification of product function characteristics all represented activities performed by specified departments. Designing and technology documentation was created on the basis of information given by the above mentioned departments. Today companies are specialized in partial technology processes. Hundreds, sometimes thousands of collaborative processes depend on workers interactions and communication in the product assembly phase. With an intensive coordination, all the manufacturing phases of one product design and technology documentation are produced, in digital form, on CAx workstation. The Product Lifecycle Management can be achieved by using specialized software solutions. Some of the solutions for the Product Lifecycle Management offer integrated portfolio for engineering design and production of products and services, which enables companies to create their own digital e-business projects

RFID Technology Use in Assembly and Disassembly Processes

Modern production conditions demand the application of the concept of distributed production. Today companies are specialized for partial technology processes. Hundreds, sometimes even thousands, of collaborative processes depend on workers’ interaction and communication in product assembly and disassembly phases. RFID technologies can be really helpful in identifying objects in terms of sustainable development, regarding disassembly, recycling and reuse. In this paper we presented VCDE system architecture and the realization method of RFID technology as well as the data acquisition using RFID technology during the product lifecycle from the design process, production, assembly, usage, and an special example is given regard- ing disassembly and recycling process

Analysis of Possible Use of Identification Technologies in Disassembly

The barcodes and Radio Frequency Identification tags that are being used during manufacturing, assembly, warehousing, and distribution could also be reused at the end of the product lifecycle for an identification of the correct disassembly process that would result in recycling of its components. The barcodes or RFID tags can be helpful in identifying objects in terms of sustainable development, regarding disassembly, recycling and reuse. In this paper, the analysis of the current applications of RFID Technology in the final phase of the product lifecycle will be presented. The simulation of the disassembly process supported by both barcode and RFID-enabled product sorting in Rockwell simulation Software Arena

TOWARD A SMART ECOSYSTEM WITH AUTOMATED SERVICES

New ICT architectures enable a better response to constant pressure on the industry and services to improve their business performance and productivity, especially in data processing. At the same time, due to the growing number of sensor modules, the amount of data that needs to be processed, in real time, is growing. Delays in communication with the cloud environment can lead to poor management decisions or user dissatisfaction. In automation and services, one of the new ICT architectures is Edge computing in the data processing. Edge computing is a networking architecture that brings computing close to the source of data in order to reduce latency and bandwidth use. Edge computing brings new power to data processing and the ability to process large amounts of data in real time. This is essential for predicting the behavior of machines, systems, or customers in order to detect errors or provide personalized service as in the case of smart vending machines. In that way, Edge computing enables taking steps toward establishing a smart ecosystem in automation and services

Laser inspection of rubber profiles

In the rubber industry, especially in the tire branch, inspection of shape and dimensions of freshly extruded rubber profiles which are components of a final product is an important problem. Accuracy of shape and dimensions of these profiles largely defines the quality of final product. Reviewed in this paper are existing solutions and inspection technologies which are in use for this type of problem. Proposed in this paper is a novel solution for the inspection of shape and dimensions which performs on a par with existing methods, while providing simplicity and cost effective design. The proposed solution employs a two-dimensional movement of a simple laser beam, which measures the distance rather than the laser plane whose reflected traces are analyzed as an image

DEVELOPMENT OF A DIDACTIC SET OF PNEUMATICS AND SERVO PNEUMATICS IN ENGINEERING EDUCATION

Control of the work piece position is one of the most difficult and most common problems in manufacturing. This problem is in most cases solved by using an electric axis with a servo or step motor, servo pneumatic or classical pneumatic components. Having this in mind, a didactic set for controlling the work piece position in vertical tubes has been developed and will be described in this paper. This system has been realized by using servo pneumatics and classical pneumatics. In this system, feedback was used for controlling the work piece position in a servo pneumatic system. The feedback was obtained by using a photoelectric sensor. The developed system is a part of the laboratory equipment used by undergraduate and graduate students in the Industrial Engineering and Mechatronics study programme at the Faculty of Technical Sciences, University of Novi Sad, as well as by individuals who already work in industry. This didactic set encourages active participation of students in class and helps them with their tasks, which include learning about the structure of the set and the way of controlling the work piece position

Mechatronic education at the Faculty of Technical Sciences Novi Sad

Nastajanje inženjerskog polja mehatronike privlači pozornost mnogih tehničkih stručnjaka, akademika i vladinih dužnosnika u posljednjih nekoliko godina, na nacionalnoj i globalnoj razini. Glavni razlog za to je da mnogi suvremeni proizvodi više nisu čisto električni i elektronski ili mehanički. Štoviše, oni su integrirani multidisciplinarni proizvodi koji su izrađeni od podsustava koji zahtijevaju inženjersko znanje iz različitih disciplina. Tako sve veći broj sveučilišta nude tečajeve, certifikate i programe na preddiplomskoj i diplomskoj razini u području mehatronike. Ovaj članak predstavlja obrazovni program mehatronike na Fakultetu tehničkih znanosti Sveučilišta u Novom Sadu u Srbiji. Osim toga, u članku je prikazana procjena studenata programa mehatronike. Provedeno istraživanje omogućilo je bolji uvid u mišljenje studenata o ovom programu, a samim tim i vrijedne povratne informacije koje će omogućiti daljnja poboljšanja programa.The emerging engineering field of mechatronics has caught the attention of many engineering professionals, academics and government officials in recent years, nationally and globally. The main reason for this is that many modern products are no longer purely electrical and electronic or mechanical. Moreover, they are integrated multidisciplinary products which are made from subsystems which require engineering knowledge of different disciplines. Hence, increasing number of universities is offering courses, certificates and programs at undergraduate and graduate levels in the area of mechatronics. This paper presents an educational program in mechatronics at the Faculty of Technical Sciences, University of Novi Sad, Serbia. In addition, student evaluation of the mechatronics program is presented. The conducted survey enabled faculty to gain more insight into student opinions about this program which provided valuable feedback for further program improvements
