Abstract
The following thesis relates to the final inspection and functional test of machines in small to middle scale production environments. Customer requirements for individual products as well as recent trends towards automation and digitization create challenges especially for small and middle-scale companies. This thesis aims at these challenges to create a concept for more efficient, secure, fast, still profitable final inspections and function tests. To illustrate this concept this thesis will examine the manufacture of an industrial shredder. Currently the status quo for the testing and functional tests of machines is a manual process and based upon paper check-lists. The basic idea is to digitize these check-lists and on this basis the goal is to find possibilities for automation of these tests and to develop a concept for a partly automated final inspection and functional test. The result consists of three expansion stages to allow autonomous inspection phases as parts of the end inspection of the machines. It enables the possibility to read machine parameters and to perform functional tests, which will be monitored by sensors and verified automatically. Key requirements for this concept have been a simple, uncomplicated method to attach the sensors, the reduction of amount of work required for personnel to operate this facet of the production, high reliability and accuracy of sensors, and finally the usage of high-end industrial components while realizing the project’s parameters in a cost-effective manner. With the proposed concept, it will be possible to automatically check almost half of the current tasks of the final inspection and functional tests and a few more tasks can be captured automatically with minimal human assistance.
