Electrotechnical testing and laser marking of motor coils

Testing Stations by AUTFORCE

Another CUBE has left our site and is now used by our customer
for electrotechnical testing and laser marking of motor coils.

The project

The advantages of our modular testing stations have become especially noticeable in this project. In the spirit of sustainability, two work steps are carried out in just one CUBE. This not only saves material and money, but also minimizes the space required for the work processes.

Keyfacts

  • Marking and testing station with laser suction and tray deposit
  • Locking and visual control included
  • Laser-tight safety door – it is not necessary to wear safety goggles
  • Camera inspection of dimensional accuracy can be added at any time
  • Cycle time: 20 seconds
  • Ergonomic design – optimally suited as a seated workstation
  • Two operations in one CUBE
  • Including data acquisition and tracing with our MES autfactory
  • Operator guidance and information via an industry-standard screen (rework instructions, key figures, measured values)

Space-saving

By performing two measurements in only one CUBE, our customer saves on the one hand the costs, but also the space for the installation area of a second device.

Ergonomic

The ergonomic design provides an optimal workplace.

Minimize errors

The automatic rejection of NIO parts minimizes the error rate of your production.

Step 1

The barcode on the route card is captured by an operator using a hand-held scanner. The test program is loaded automatically and the operator can now insert the component into the CUBE.

Step 2

A vision sensor is used to check if the component has already been lasered. If no mark was detected, the coil is moved to the second position.

Step 3

At the second position, an electrotechnical test for high voltage and winding short circuit is performed. Once the test results are validated, the component is either given a serial number and an OK laser mark or the component is marked with the error code of the NOK measurement.

Step 4

After the inspection, the components are positioned again at inspection position one. A vision sensor checks the laser marking. If the component was defective, the coil ends are bent with a pneumatic cylinder. The component thus no longer fits into the designated good parts deposit and cannot be accidentally reintroduced into the process.

Step 5

After the process is finished, the automation gate opens and the component can be removed. When the start button is pressed, a second vision sensor checks the filling of the tray. As soon as 18 components are in the tray, a pneumatic stopper opens and the full deposit tray is replaced by an empty one via a roller conveyor.
