In order to achieve the shortest possible cycle times of less than 30 seconds, the current sensors should be contacted fully automatically after placement by hand. If a faulty DUT is detected, it should be ejected automatically. Since different versions of the current sensors are tested on one system, the test adapter must be exchangeable in less than 5 minutes. After the exchange, it must be checked whether the suitable adapter has been installed for the respective DUT.
By using a rotary indexing table with three test stations, it was not only possible to build an extremely space-saving system, the test time was also minimized to a maximum of 30 seconds per DUT. The user is protected from the movement of the turntable by a protective housing in combination with two-hand operation. This avoids unintentional intervention and the risk of crushing.
Manual insertion of the DUT and correct positioning via a centering bolt. By actuating the two-hand control, the DUT proceeds to the next station.
The DUT is contacted fully automatically with current loops and a function as well as a hipot test is carried out. By actuating the two-hand control again, the DUT proceeds to the next station.
If a DUT is detected as faulty, it is automatically sorted out in station 3 via a gripper. The “Passed“-DUT proceed to the first station where they can be removed and labelled by the user.
