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 mobile phone chargers in a globalized market, where transparency in processes is key. The main objective is to perform electrical tests with traceability using QR code scanning and programming through the National Instruments LabWindows/CVI software. The study begins with the contextualization of the problem, highlighting the importance of traceability to ensure the quality and reliability of electronic products, such as cell phone chargers. It was observed the need to implement methods that streamline the testing process, 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 carried out 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 the chargers, organizing them in numerical sequence for registration in a .txt file. Then, the second step performs data collection, performs the necessary electrical tests, and generates a .csv file for local storage, along with a .xml file for registration in the company's database. The results include a significant improvement in the efficiency of the testing process, the assurance of complete traceability of the loaders and the optimization of the production time of the equipment.
