IMPLEMENTATION OF AUTOMATED TORQUE SYSTEM TO PREVENT FASTENING FAILURES IN ASSEMBLY LINES VIA IOT

Resumo

This article addresses the implementation of an automated torque control system in an injection molding company. The study aims to eliminate the recurring and costly problem of shipping products with missing screws, which generated costs and negatively impacted customer relationships. The main objective is to implement and validate a system capable of eliminating the occurrence of operational failures on the assembly line. The study follows the Design Science Research (DSR) method to guide its steps. The proposed solution modifies the existing assembly process, integrating a digital counter into the Desoutter screwdriver and making crucial changes to the electrical control. This ensures that the part is released only after the correct counting of 8 torque pulses, eliminating vulnerability to fraud. A supervisory system using ESP32 and Google Sheets also implements real-time production monitoring, operational data collection and effective failure control. The results are positive, fully achieving the objective of eliminating fastening failures and the delivery of parts without the necessary screws. The solution has proven to be effective and reliable, validated by practical tests with experts and user surveys. Users highlight its functionality, reliability and the value of real-time monitoring, generating tangible economic benefits for the company. The integration of automated torque control, Poka-Yoke and monitoring via IoT proves to be a viable approach for quality assurance in assembly processes.
