Abstract

A bulk component feeder is provided for delivering components contained with a bulk cassette. The feeder includes a feeder housing defining a component cassette receiving area. The receiving area includes a cassette mounting means for registration with the cassette, and the housing defines an opening for receiving components from the cassette. A gate slidable within the cassette receiving area interfaces with a mounting means, and the gate is slidable to cover the opening in a closed position and uncover the opening in an open position upon attachment of the cassette to the housing. A spring is used to bias the gate toward the closed position, and a latch is mounted to the housing and is engagable with the gate to prevent sliding of the gale toward the open position and thereby prevent installation of the cassette.

Claims

1. A bulk circuit component feeder for delivering components contained within a cassette, said feeder comprising:

a feeder housing defining a component cassette receiving area, said receiving area including a cassette mounting means for registration with said cassette, said housing defining an opening for receiving components from said cassette;

a gate slidable within said cassette receiving area of said housing and interfacing with said mounting means, said gate slidable to cover said opening in a closed position and uncover said opening in an open position upon the attachment of said cassette to said housing;

a spring positioned to bias said gate toward said closed position; and

a biased latch mounted to said housing and engageable with said gate for preventing sliding of said gate toward the open position.

2. The invention of claim 1 wherein said latch further comprises a plunger extendable from said housing through an opening defined in said gate when in said closed position, wherein said plunger prevents movement of said gate toward said open position.

3. The invention of claim 2 further comprising a solenoid linked to said plunger for raising said plunger from said opening defined in said gate upon activation of said solenoid to thereby disengage said latch from said gate.

4. The invention of claim 3 wherein said plunger is biased toward said gate.

5. The invention of claim 4 wherein said solenoid is fixed to said housing.

6. The invention of claim 3 wherein said cassette includes a mounting member slidably engageable with said mounting means of said receiving area, said mounting member configured to slidably displace said gate toward said open position upon engagement with said mounting means.

7. The invention of claim 1 further comprising first identification means mounted on said cassette;

second identification means associated with said feeder; and

a scanning device for reading said first and second identification means.

8. The invention of claim 5 further comprising processing means for determining whether said cassette is properly authorized for installation to said feeder.

9. The invention of claim 8 further comprising a memory storing data relating to the components contained within said cassette having a first identification means, said memory in communication with said processing means, wherein said processing means compares the data read by a scanning device with information in said memory.

10. The invention of claim 9 wherein said solenoid is linked to said processing means, said processing means being able to activate said solenoid upon determining that said cassette is properly authorized for installation to said feeder.

11. The invention of claim 10 further comprising timing means in communication with said processing means, said timing means for deactivating said solenoid after a preset period of time.

12. A bulk circuit component feeder for delivering components contained within a component cassette, said feeder comprising:

a feeder housing;

a cassette receiving area on said housing, said receiving area including a pair of spaced apart sidewalls adapted to receive said cassette therebetween;

a gate slidably mounted within said cassette receiving area, said gate being slidably displaceable from a closed position to an open position by a portion of said cassette to allow insertion of said cassette into said receiving area, said gate being biased toward said closed position; and

a plunger mounted to said housing and configured to selectively prevent the slidable displacement of said gate by said cassette, thereby preventing the insertion of said cassette into said receiving area.

13. The invention of claim 12 further comprising alignment means on said housing for registration with said cassette to guide said cassette into position during insertion of said cassette into said receiving area.

14. The invention of claim 13 wherein said plunger is extendable between said housing and an opening defined in said gate when in said closed position, wherein said plunger prevents movement of said gate toward said open position.

15. The invention of claim 14 further comprising a solenoid mounted on said housing for raising said plunger from said opening defined in said gate upon activation of said solenoid.

16. The invention of claim 15 wherein said plunger is biased toward said gate.

17. The invention of claim 15 further comprising first identification means mounted on said cassette;

second identification means associated with said feeder; and

a scanning device for reading said first and second identification means.

18. The invention of claim 17 further comprising verification means for determining whether said cassette is properly authorized for installation to said feeder.

19. The invention of claim 18 further comprising a memory storing data relating to the components contained within said cassette having said first identification means;

said memory in communication with said verification means, wherein said verification means compares the data read by said scanning device from said first and second identification means with information in said memory.

20. The invention of claim 19 wherein said solenoid is linked to said verification means, said verification means being able to activate said solenoid upon determining that said cassette is properly authorized for installation to said feeder.

21. The invention of claim 20 further comprising timing means in communication with said verification means, said timing means for deactivating said solenoid after a preset period of time.

22. A method for supplying a plurality of circuit components for installation to a circuit board, said method comprising the steps of:

providing a bulk cassette containing a plurality of circuit components, said cassette defining at least one opening for supplying said components therethrough, said cassette including mounting grooves and an identification means on said cassette for identifying the type of bulk components contained in said cassette;

providing at least one bulk component feeder for delivering said components to a component mounting device, said feeder including a housing defining a mounting means for registration with said grooves on said cassette and an opening for receiving components from said cassette, a gate mounted on said housing to slidably cover said opening, and a latch releasably engageable with said gate to prevent the sliding of said gate;

scanning the identification means on said cassette to determine the type of bulk components in said bulk cassette; and

releasing said latch based on said scanning to allow said gate to uncover said opening.

23. The method of claim 22 further comprising the steps of scanning the identification means on said bulk component feeder and determining whether the bulk component feeder is authorized to accept the type of bulk components in said bulk cassette.
