Sistema com aplicativo híbrido para a automação do estágio XY do porta-amostras do equipamento de plasma atmosférico

Abstract

Automation replaces human work, controlling operational processes through mechanical or electronic devices, ensuring greater safety and accuracy. It is proposed to automate the XY stage of the sample holder of the atmospheric plasma equipment of the Laboratory of Thin Films and Plasma Processes at the Federal University of Triângulo Mineiro, since the handling of this equipment can cause electric shock to the user. This work can be divided into two stages: the development of hardware and software. The hardware consists of supports and couplers for fixing and transmitting motion from the stepper motors to an equipment table. It also consists of electronic connections with Arduino©, stepper motors, drivers motor, buzzer and the Bluetooth module. For the software, two algorithms were developed, the first is the program developed in Arduino© for the microcontroller to execute the desired movements; and the second is the application developed in Ionic© that sends form information to Arduino© via Bluetooth communication. The proposed development results in the following process: filling in the form with the displacements and speeds desired by the user in the application. Then, the application sends this information to the Arduino© via Bluetooth communication and, immediately after the audible warning of the start of operation, the microcontroller executes the movement with the activation of the stepper motors and ends with the audible warning. The investment for the construction of this system was R$ 191.34 and it is considered innovative because it presents an unprecedented proposal for the solution of accidents involving electric shock in the sample holder of the atmospheric plasma equipment. In addition, each software is classified in the software registry of the National Institute of Industrial Property.
