Resumen

The world is currently experiencing a crisis, caused by SARS-CoV-2 and a viral mutation. Given this, the mechatronic system is proposed that allows disinfecting contaminated surfaces. This device makes it possible to disinfect polyethylene terephthalate (PET) bottles by applying short-wave UVC rays from 200 to 280 nm, which generates a germicidal effect. The machine consists of a UVC chamber, transport, and a control system. For this, the methodology of the Association of German Engineers (VDI 2206) was used, taking into account the Inventor, TIA Portal, and Factory IO software, managing to develop the system whose light-emitting diodes inside the camera project type C ultraviolet light, camera protected by strips of plastic sheet (ABS) acrylonitrile butadiene styrene anti-ultraviolet light that blocks the projection wave up to 98% of the radiation; the recycled PET bottles are moved through a linear conveyor belt that supports a maximum weight of 200 kg, controlled by a control panel. Obtaining the results in this research focused on the design of the prototype, with a feasible structural system thanks to its maximum efficiency in the disinfection process. It is concluded that it is feasible to design a machine that projects ultraviolet rays to disinfect recycled PET bottles to eliminate viruses, parasites, fungi, and bacteria.
