Mechatronic System for Management and Control of a Device for Applying a Polymer Coating

This article presents a comprehensive study on the design, simulation, and programming of a mechatronic device for the precise application of polymer coatings to flat parts. The device utilizes a two-coordinate system controlled by NEMA 17 motors to position the spraying mechanism accurately. The objective is to achieve a uniform and controlled deposition of the polymer, improving the coating quality and overall efficiency of the process. The simulation of the mechatronic device is performed using advanced modeling techniques, allowing for a virtual representation of its mechanical components and their interactions. The simulation results demonstrate the effectiveness of the device in achieving the desired coating outcomes while minimizing material waste and processing time. To realize the functionality of the mechatronic device, a customized control program is developed using a suitable programming language. The program enables the device to receive input instructions, such as a black and white image representing the desired coating pattern. The program processes the image, extracting the relevant information, and generates control signals for the motors and polymer spraying mechanism. These control signals govern the precise movement of the two-coordinate system and the activation of the spraying mechanism at the appropriate locations, ensuring an accurate replication of the desired coating pattern. Experimental validation of the mechatronic device is conducted using physical prototypes, where the programmed control algorithm is implemented on an Arduino microcontroller. The experimental results highlight the device's reliability, repeatability, and robustness in achieving consistent and high-quality coatings on various flat parts. The presented mechatronic device offers significant advantages in terms of precision, efficiency, and automation in the application of polymer coatings. The findings of this research contribute to the advancement of mechatronics and its applications in industrial coating operations, paving the way for enhanced product quality, reduced costs, and increased productivity.
