Definitions

  • the invention relates to a device for forwarding components accommodated in individual, separate receptacles of an input magazine, in particular integrated chips, to individual, separate receptacles of an output magazine, with a test device arranged between the input magazine and the output magazine, which test device uses a first transport device individual components from the receptacles of the input magazine are fed one after the other for testing and which delivers the respectively tested components to a second transport device which allows the relevant components to be delivered to receptacles of the output magazine defined by the testing device.
  • EP-A1-7650 A device of the type described above is generally already known (EP-A1-7650).
  • the disadvantage of this known device is that it involves a relatively high level of design effort is required to deliver the individual components tested from the measuring device to the output magazine.
  • Another disadvantage is that the assignment of the individual shots of the output magazine can not be easily adapted to the current needs.
  • the invention is therefore based on the object to show a way how the forwarding of components from the measuring device to the output magazine can be achieved with a device of the type mentioned with a particularly low design effort and how at the same time the respective component in one such a recording can be introduced which belongs to any component test or measurement class per se.
  • the object outlined above is achieved according to the invention in a device of the type mentioned at the outset in that storage and display devices are associated with the individual images of the output magazine, each of which is capable of storing and displaying information corresponding to a component test or measurement class, and that the second transport device can be moved in relation to the receptacles of the output magazine using information stored in the individual storage and display devices in such a way that a component belonging to the test device or to a certain component test or measurement class belongs to this test or Measurement class associated recording or in the absence of such a recording in a component test or measurement class still assignable recording of the output magazine while holding and displaying this assignment in or by the the storage and display device associated with the recording in question can be emitted.
  • the invention has the advantage that it is possible to make do with a relatively low overall design effort in order to be able to insert the tested components, which are respectively delivered by the test device to the second transport device, into the receptacles of the output magazine in question.
  • the advantage here is that the assignment of the relevant recordings of the output magazine to the individual component measurement or test classes can be determined automatically, so that a test or measurement class range is not to be defined beforehand, which is in the course of operation as turns out to be too tight.
  • a storage area of a storage device and a multi-segment display device are expediently associated with each receptacle of the output magazine. This has the advantage of a particularly low outlay in terms of recording and displaying the respective assignment between a recording of the output magazine and the specified test or measurement class.
  • the relevant memory device can be formed by a memory device assigned to or provided by the multi-segment display device and / or by a memory device provided in a control arrangement.
  • the respective storage and display device can preferably be returned to its initial state after its associated receptacle has been emptied. This advantageously ensures that each emptied receptacle is ready for use again.
  • Each receptacle expediently has a signaling device which, when the receptacle in question is completely filled by components, marks this receptacle as no longer receivable for components. This has the advantage that a component-filled receptacle is not incorrectly supplied with other components.
  • the second transport device is preferably able to accommodate only one component at a time. This has the advantage of a second transport device that is particularly easy to set up.
  • the second transport device can expediently be moved with respect to the receptacles of the output magazine by means of a cable pull arrangement and can be adjusted between a component delivery position and a component blocking position by means of a pivoting device. This has the advantage that an overall particularly low design effort for the movement and adjustment of the second transport device can be used.
  • the receptacles of the output magazine are preferably closed on their component delivery side by a spring element which can be brought from a locked position into a release position by means of an emptying device. This results in the advantage of a particularly low construction effort for the formation of the receptacles of the output magazine.

  • the relevant transport device 5 is, as can be seen from FIG. 1, attached to the base plate 9.
  • a separating device 6 is indicated in the entrance area of the testing device 4 in FIG. 1. This separating device is used to forward its components fed from the input magazine 2 individually one after the other into a testing or measuring area of the testing device 4. In the area of the input magazine 2, devices can expediently be provided which bring the area in question and thus the components located therein to a desired temperature. Typically, the equipment in question will be heating equipment.
