Abstract

U radu je prikazan cijeli proces robotizacije točkastog zavarivanja karoserija vozila te niz izazova i problema koji se javljaju. Proces se odvio u tvornici Revoz, tvrtke Renault, na području Republike Slovenije. Prednosti i nedostaci robotskog zavarivanja, te parametri korišteni za odabir robota u obavljanju posla su navedeni. Pokazani su načini rada prije robotizacije i modifikacije postojećih konstrukcija koje su se trebale promjeniti da bi roboti mogli zavarivati. Plan radnog mjesta robota u tvornici je priloţen, te će se analizirati radni prostori u kojima će pojedini roboti obavljati zadatke. Navedeni su svi elementi u otoku i njihova uloga u cijelom procesu robotizacije. Detaljnije su opisana zavarna kliješta i njihov odabir, pri čemu je opisivana njihova mehanička karakteristika, ali i konkretni tipovi za pojedini autodio. Navedene su i točke zavara na nekim autodijelovima koje će se morati zavariti. Nadalje se u završnoj fazi procesa obraĎivao sami programski kod jednog robota. Za kraj se evidentira vrijeme utrošeno na cijelokupan proces automatizacije/robotizacije procesa, te se iznose očekivanja od cijelog sustava.

Abstract (english)

This paper presents the whole automotive welding process of the vehicle body and a series of challenges and problems that arise. The process took place at the Revoz factory, Renault, in the territory of the Republic of Slovenia. The advantages and disadvantages of robot welding, as well as the parameters used to select robots in performing the work are listed. Methods have been demonstrated before the robotization and modification of the existing structures that should be changed to enable the robot to weld. The factory robotic work plan is attached, and work spaces will be analyzed in which individual robots will perform tasks. All elements in the cell are listed and their role in the entire robotization process. More specifically, the welding pliers and their selection are described in detail, describing their mechanical characteristics, as well as specific types for individual autodies. There are also points of disturbance on some auto parts that will have to be sealed. Further, in the final phase of the process, the program code of a robot was processed. For the end, the time spent on the entire process automation / robotization process is recorded, and the expectations of the whole system are high.
