Abstract

A device for the automatic cleaning, testing, and sorting of discoidal, flat substrates (9, 9', . . . ) for example magnetic memory plates, having three support mandrels (12, 13, 23) for the substrates (9, 9', . . . ) to be treated, three magazines (6, 7, 8) to deposit the treated and the untreated substrates (9, 9', . . . ), and having a transporting device fixed to a machine frame (2) or a machine support with several transferring arms (14, 15, 16) which can be moved on several levels and which are equipped with gripping devices (20, 21, 22) is provided with a motor-driven first support mandrel (23) rotating round its longitudinal axis (r) and with a nozzle (25, 26) disposed directly adjacent to said support mandrel in order to apply a cleaning liquid onto the substrate (9, 9', . . . ) which is firmly held by the first support mandrel. Moreover, each of the two further support mandrels (12, 13) disposed next to the first support mandrel (23) are provided with a scanning and testing device (27); the first transferring arm (14, 14', . . . ) serves to transport the substrate (9, 9', . . . ) from the first magazine (6) to the first support mandrel (23) and the second transferring arm…
