The objective of this thesis was to develop and construct an automatic test device for calibration and final control of linear magnetic encoders. These encoders provide information about position in the linear movement. Because device, which was currently using in the production, was slow and did not allow automatic calibration of products, there was possibility that an error occurs in the production process. Therefore it was necessary to develop a device that enables automatic calibration of products and is faster and more reliable while reducing the influence of human factor.
Because we have to make a rather complex device, we divided the work. I started my task with assembling mechanical parts, which we designed in cooperation with mechanical engineers, based on the experiences we have gained while working with the old test device. Then I started with electrical design for control electronics and ordered individual components of the device. Then I started with assembling the device. When I assembled the whole device, I started with testing. Main program was made by my experienced coworker Gregor Dolšak. He made transparent user interface and in addition took care that test procedures can be made for individual products using a set of commands and test steps. My task was also to write test procedures for all types of product. Currently we have over 50 different test procedures saved, but this number is increasing with the need of testing new products. When I fully assembled the device, tested how it works and wrote all test procedures, I handed device to production and performed training for operators. I wrote instructions for working and maintenance and drew a detailed schematic of the device.
The final product is an automatic test device, which is working in production for the fourth consecutive year. I take care for regularly servicing and all updates of device according to new products that need to be tested.
