Control of a coating robot

Problem definition

This project concerned the control of a coating robot which paints parts on a rack.

The client approached us with the problem that various factors during the painting process could cause too few parts being painted for a job or too many rejected parts being produced. This led to the re-production of parts for already closed orders. It was the wish of the client to bring more transparency into the process, so that future completed orders would not have to be restarted.

In order to create the desired transparency, the following measures were proposed:

  • the recording and control of the racks onto which parts are mounted, as well as the associated equipping of the respective workstations with write/recording points. The aim is to record the number of parts per rack and to output the correct colour for painting.
  • equipping the chain conveyor with AutoID technology to control the chain speed with regard to the implementation of an automated painting process by robots

The developed concept was implemented together with the client. Various points in the process chain were equipped with RFID. The pre- and post-processing stations were provided with writing points so that the employees are able to attach the information about the corresponding colour and number of parts to each rack.
