Abstract [en]

The project is done with the intension of automating the nail gun tool for the company Essve which produces tools and solutions for the prefab industries. The company had a set of specifications which had to be achieved while automating the system. The company also wanted to test how reliable the system is and how much the tool can handle before it wears off. This report focuses on the quality inspection part of the project and the means to find the suitable inspection system that would help in validating and testing the system based on the company specifications. As a part of quality inspection, camera and laser systems are used to inspect the nailing quality and the best system is chosen. Also, HMI is made for visualizing the process and for documenting the quality results. The components are basically mounted to the tool, provided for testing by the company, and the tool is mounted to the robot's endeffector with the help of CAD models and 3D printers. The test experiments and output result documentations are done with the help of robot and PLC programming. The results of the testing show that the desired system can be obtained with minimum errors. The camera system is best suited for selecting the layout of the patterns rather than using it for inspection purpose. Whereas, the laser system shows a prominent result in determining the quality of the nailing process by using laser profiles. The IO configurations helped in communicating all the outputs from all the sub systems to the robot controller and PLC through which the monitoring of the process is made possible with the help of an HMI screen. The presented product's design and testing gives a perfect example of the application of robot systems in the automated industrial environment and helps in understanding the procedures of testing and validation of the product tool before it is actually used in a real manufacturing sector.
