Definitions

  • the invention relates to a device for testing and sorting electronic components, in particular integrated chips, with an input magazine for the components to be tested, with a test device to which the components to be tested are successively fed from the input magazine, with an output magazine which has separate receiving channels , each of which is assigned to a specific test class, with a transport device arranged between the test device and the output magazine, which takes over the tested components from the test device, then transported to and from the corresponding receiving channel of the output magazine depending on the test class determined by the test device outputs, with a display device for each of the receiving channels, by means of which it is displayed to which test class the components located in the relevant receiving channel have been assigned, with a signaling device which reports the complete filling of each receiving channel with components, and with a computer for function control of the device, the information from the test device about the respectively determined test class and from a memory which is an internal memory device of the computer or an external memory device assigned to the display device , Information about the assignment of magazine channels of the output magazine to certain test classes can be supplied.
  • Such a device is known (EP-A1-7650).
  • a two-segment display element and a display lamp are assigned to each receiving channel of the output magazine.
  • the two-segment display element shows the test class in which the components that have been sorted into the relevant receiving channel have been classified.
  • the indicator lamp lights up when the relevant recording channel is full.
  • the invention is therefore based on the object of designing a device of the type described at the outset in such a way that operation is automated to a greater extent and thus the constant presence of an operator can largely be dispensed with.
  • the computer also receives information about the filling state of the receiving channels of the output magazine from the signaling device, and that the computer is programmed, by evaluating the information supplied to it, in such a way that, if the test class is new a component to be sorted into the output magazine has already been assigned, a recording channel is already assigned, but this recording channel is full, or, if the recording class that was determined for a component to be sorted into the output magazine has not yet been assigned, this recording class has a free recording channel assigns, stores this assignment information in the memory, activates the display device of this new recording channel by displaying the test class assigned to the new recording channel, causes the transport device to approach this new recording channel and after emptying one full recording channel deletes the corresponding assignment information in the memory and deactivates the display device for this recording channel.
  • the solution according to the invention ensures that a full receiving channel no longer has to be emptied by an operator present in order to avoid interrupting the operation of the device. Rather, the computer selects a recording channel that has hitherto been empty and has not yet been assigned to a test class and is then assigned to the same test class as a recording channel that has just become full. The components classified in this test class during further operation of the device can therefore be stored in this new receiving channel. In other words, this means that there is no fixed assignment between the test classes and the receiving channels of the original magazine; rather, the assignment by the computer in connection with the memory during the operation of the device is made according to the needs, i.e. after the components have been obtained in the individual test classes.
  • An expedient embodiment of the invention can consist in that a light barrier arrangement is provided at the output of the receiving channels of the output magazine, which arrangement supplies the computer with corresponding information when emptying a receiving channel.
  • a light barrier arrangement is provided at the output of the receiving channels of the output magazine, which arrangement supplies the computer with corresponding information when emptying a receiving channel.
  • a further embodiment of the invention can consist in that the signaling device is formed by a light barrier arrangement provided at the output of the receiving channels of the output magazine.

At a distance from the support rod 13, the input magazine 2 has at least one roller 10, with which it can run along on the base plate when displaced.
  • 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.
