The cooling units are fed into an evacuation circuit from the final assembly line. The cooling units are moved onto the workpiece carriers equipped with evacuation pumps via lift transfer and alignment stations. After connecting the evacuation hoses to the refrigerator, the appliances move through the circuit according to the evacuation time and are uncoupled from the evacuation hoses again when the specified parameters have been reached and are cycled on to the next test station.
In the second station, the test circuit, the refrigerators are also moved onto workpiece carriers, which are equipped with appropriate test technology. After fully automatic electrical contacting, the test circuit is run and at the end the appliances are automatically decontacted again and removed from the workpiece carriers. Any deviations from the target values are automatically assigned to the corresponding appliance via barcode scanners, so that it can be automatically separated out in the further transport process and treated accordingly.
The appliances are then rotated and lowered to an ergonomically suitable level for the final inspection using vertical conveyors. Here, the appliances are once again aligned and electrically contacted and tested.
After passing the final inspection, the appliances move into a vertical conveyor, where they are turned again for appropriate onward transport and then move into a buffer.
In addition to the conveyor technology, the scope of delivery also included the workpiece carriers with installed evacuation and testing technology, the electrical device contacting, identification systems and the complete control technology.
