  • Safety interlock device for a standard manufacturing interface arm and equipment
    Patent number: 5803696
    Abstract: A safety interlock system and method of unloading a standard manufacturing cassette using a safety interlock system are described which prevent the robotic arm used to unload the cassettes from unloading the cassette unless the cassette is in the proper unloading position. The safety interlock system uses a light beam emitted by a light source and illuminating a light sensitive switch if the cassette is not in the proper unloading position. If the cassette is in the proper unloading position the cassette interrupts the light beam and the light sensitive switch is not illuminated. Illuminating the light sensitive switch energizes a relay primary coil which interrupts power delivered to the electrical control unit of the robotic arm and activates an alarm unit.
