Abstract

A method and apparatus for assembling multiple component products using automated assembly equipment having predetermined locations for loading of components or component compartments. The invention includes a component identifier which reads indicia of component identity from components or component compartments, and a location indicator which indicates a proper location for loading and identified component or component compartment. The invention also contemplates a sensor that senses the placement of components or component compartments in the locations of the assembly machine, and a disabling device which disables the assembly machine if components or component compartments are misplaced.

Claims

1. A system for assembling multiple component products, comprising:

an assembly machine which assembles products using components retrieved from a plurality of compartments located at a corresponding plurality of locations, each compartment located according to a type of component stored within;

a component identifier that identifies the type of component stored in each compartment by analyzing indicia of the components or component compartments; and

at least one location indicator, responsive to the component identifier, for producing an indication signal of the corresponding location of each component compartment or component after the type of component has been identified.

3. The system of claim 1, further comprising, an error indicator that indicates if a compartment has not been placed in a corresponding location indicated by the location indicator.

4. The system of claim 3, said error indicator indicating if a compartment has not been placed in said corresponding location indicated by the location indicator within a predetermined amount of time.

5. The system of claim 4, said predetermined amount of time been selected to correspond to a time required to load the compartment in said corresponding location.

6. The system of claim 1, further comprising, a disabling device which disables said assembly machine at the beginning of a machine loading time period, and which enables said assembly machine after all compartments are placed in their corresponding locations.

7. The system of claim 1 further comprising, a disabling device that disables said assembly machine, after loading of said machine has been completed, if any compartment is removed from a location, and that enables said machine once all emptied locations have been filled with corresponding compartments.

8. The system of claim 1, wherein the component identifier comprises an optical reader.

9. The system of claim 8, wherein the indicia of the components or compartments comprises optically readable indicia.

10. The system of claim 9, wherein the optically readable indicia is a bar code.

2. The system of claim further comprising, at least one compartment sensor that senses whether a compartment is present in a previously identified location.

11. The system of claim wherein the location indicator comprises an individual visual indicators corresponding to each location.

12. The system of claim 11, wherein said visual indicators comprise light emitting diodes.

13. A system for assembling multiple component products, comprising:

a machine which assembles products using components retrieved from a plurality of compartments, each compartment being located in a corresponding one of a plurality of locations according to a type of component stored within each compartment;

an information processor;

a component identifier, connected to the information processor, that identifies a type of component stored in a compartment, said information processor operating to determine a proper location of each identified compartment; and

at least one location indicator, connected to and controlled by the information processor, that indicates the proper location of each identified compartment.

14. The system of claim 13, further comprising at least one compartment sensor that senses whether a compartment is present in a previously identified location.

15. The system of claim 13, further comprising one compartment sensor per location.

16. The system of claim 13, further comprising an error indicator which indicates if a compartment has not been placed in a location indicated by the location indicator.

17. The system of claim 16, said error indicator indicating if a compartment has not been placed in a location indicated by the location indicator within a predetermined period.

18. The system of claim 17, said predetermined time period being selected to correspond to a time required to load a compartment in a corresponding location.

19. The system of claim 13, further comprising a disabling device that disables said assembly machine at the beginning of a loading operation, and that enables said assembly machine after all compartments are placed n corresponding locations.

20. The system of claim 13 further comprising a disabling device that disables said assembly machine, after proper loading of said machine is complete, if any compartment is removed from a location, and that enables said assembly machine once all emptied locations have been filled with corresponding compartments.

21. The system of claim 13, wherein the component identifier comprises an optical reader.

22. The system of claim 21, wherein the indicia of the components or compartments comprises optically readable indicia.

23. The system of claim 22, wherein the optically readable indicia comprises a bar code.

24. The system of claim 13, wherein the location indicator comprises an individual visual indicator corresponding to each location.

25. The invention of claim 24, wherein said visual indicator comprises a light emitting diode.

26. The system of claim 13, wherein the assembly machine comprises:

a pick and place machine; and

a tape and reel feeding system.

27. The system of claim 13, where the information processor comprises:

a computer with memory; and

a digital I/O circuit that facilitates communication between the computer and the component identifier and the location indicators.

28. The system of claim 27, further comprising a relay circuit connected to and controlled by the computer, for disabling the assembly machine if all locations are not loaded with compartments containing the correct type of component.
