Zasnova in izdelava avtomatskega navijalca folije

ŠABIĆ, SANDI (author), Logar, Vito (mentor)

Cilji diplomskega dela so zasnova, izdelava in testiranje naprave za navijanje folije. To pomeni razvoj tiskanega vezja, izdelavo tiskanega vezja ter izdelavo mehanskega dela. V prostem času se ukvarjam tudi z mehaniko, zato mi je bil izziv izdelati tudi mehanski del. V praktičnem delu sem izdelal vezje s pomočjo ploščice Arduino in testne ploščice, nato pa narisal shemo in tiskano vezje, s pomočjo programa Eagle CadSoft. Izdelavo tiskanine sem poskusil narediti tudi doma, kar mi je uspelo, vendar je bila tiskanina velika, zato sem narisal manjšo dvoslojno ploščico in jo dal izdelati proizvajalcu tiskanin. Na ploščico sem zaspajkal komponente, na mikrokrmilnik naložil Arduino bootloader ter napisal program. Ta je ključnega pomena, saj je komunikacija med ultrazvočnim varilnikom in koračnim motorjem. Tiskano vezje, prikazovalnik OLED in tipke sem namestil v ohišje, za koračni motor pa sem naredil ogrodje iz aluminija. Navijalec sem priključil na ultrazvočni varilnik, ki sem mu moral nastaviti in pravilno konfigurirati izhod. Na koncu sem dobil delujoč stroj, ki olajšuje delo v proizvodnji. Tako lahko delo poteka hitreje in je operater stroja manj obremenjen.

Abstract

In the bachelor’s thesis, I set myself a goal of making a product from the idea to the final product. This means the development of a printed circuit board, the production of a printed circuit board, and the production of a mechanical part. In my free time, I also deal with mechanics and it was also a challenge to produce a mechanical part. In the practical part, I first made a circuit with an Arduino board and a test board when the circuit was working. Then, I drew a schematic diagram and the printed circuit with the program Eagle CadSoft. I wanted to etch PCB at home, which I managed. However, the dimensions and the design of PCB was quite large, so I drew a small two-sided PCB and sent it to the company that produces PCBs in Germany. I soldered the components on the PCB and loaded the Arduino bootloader to Atmega328au and wrote the program. The program is crucial because it is the connection between the Ultrasonic welding machine and the stepper motor. I mounted the printed circuit board, the OLED display, and the buttons into the casing. I made the aluminum frame for the stepper motor. I connected the winder with an ultrasonic welder and I had to configure and correctly set the output type. In the end, I got a working machine that facilitates work in the production. This way, work can be done faster and the machine operator in less tired.
