CREATION OF APPLICATIONS FOR FUNCTIONAL TEST SYSTEM WITH TRACEABILITY FOR CELL PHONE CHARGERS

Abstract

This project addresses the growing need to ensure the traceability and quality of cell phone chargers in a globalized market, where transparency in processes is essential. The main objective is to perform electrical tests with traceability using QR code reading and programming through the LabWindows/CVI software from National Instruments. The study begins by contextualizing the problem, highlighting the importance of traceability to ensure the quality and reliability of electronic products, such as cell phone chargers. The need to implement methods that streamline the testing process was observed, aiming to maximize production efficiency. The materials and methods employed involve the use of LabWindows/CVI software, an ANSI C development environment specific for test and measurement applications. In addition, observations were made in the charger testing sector to identify gaps in the process and determine the best strategies to implement traceability. In the proposed process, the first step consists of reading the QR code of the ruler and chargers, organizing them in numerical sequence for recording in a .txt file. The second stage then collects data, performs the necessary electrical tests and generates a .csv file for local storage, along with an .xml file for registration in the company database. The results include significantly improving the efficiency of the testing process, ensuring complete traceability of the chargers and optimizing the production time of the equipment.
