Even in highly automated production, many work processes need to be performed manually. Technicians need to be vigilant if production work processes are to run smoothly. When dealing with individualized products, information on the work to be done can change regularly. And when that happens, it is important that tools are used correctly to ensure both quality as well as the safety of technicians.
Fraunhofer IIS develops smart sensors to record manual job processes and is solving a diverse range of issues concerning digitization, quality assurance and increasing the flexibility of manual job processes during assembly.
Have tasks (such as screwed connections) been correctly and fully completed? Has the tool been used on the correct workpiece (e.g., car door) and at the correct location (e.g., position of the screw hole)? Has the tool been moved from its prescribed working area? Where is the tool? What is happening right now with the tool?
The Fraunhofer IIS smart sensors can be connected as detachable add-on modules to handheld tools, such as battery-powered or pneumatic screwdrivers. The sensor module networks the tool with the IT system to accept work assignments and report back on the status of the work-in-progress to the completion of the assignment.
This allows the various risks associated with different screw joint characteristics, such as the risk of a malfunction or even the risk to life and limb, to be quickly detected while quality processes are steadily improved.
