For the perfect rotation.
Automatic component coding and testing in medical technology.
Medical technology demands maximum precision and safety. The international standards that have to be met are correspondingly strict. This was also the case in our project for a leading manufacturer of laboratory centrifuges.
Such centrifuges are operated for specific applications with different rotors that hold the samples during centrifugation. These rotors rotate at speeds of up to 18,000 rpm and it is therefore crucial that the rotor and the selected program match in order to rule out safety risks. To ensure this, the rotors are coded with permanent magnets that are read by the centrifuge. The task of our system is to code and test these components.
When it counts: Absolute reliability in component coding and testing with complete traceability.
In the guided manual work station, the inserted test rotor is first identified using a QR code with a scanning unit. The almost free-floating test arm developed by us can now be positioned ergonomically above the rotor to be tested. The inspection arm then writes up to 30 product characteristics into an NFC tag on the rotor and locks it. All parameters are written in parallel to an SQL database for documentation purposes. The coding is used to identify the rotor in the subsequent production process. In a further process step, the permanent magnets of the rotor, which characterize its product properties, are read out using Hall sensors to check whether the measured value and the characteristic data of the product variant are congruent.
Compact solutions for medical technology.
The space requirement of a system is also a relevant cost factor in medical technology. For this reason, a hand-guided, particularly compact system was realized in this specific case, which combines all the required functions in a very small space. We briefly present the system in the video.
User guidance that leaves no questions unanswered.
In order to rule out operating errors and thus hazards during operation, we have designed the system to be inherently safe from the outset.
Another aspect for operational safety, but also for the efficient operation of the system, is the user concept.
The operator is guided through the individual work steps via an HMI display. Audio-visual feedback helps him to initiate the next work step or to react if necessary. This concept eliminates the need for additional, cost-intensive safety devices.
