Abstract

An apparatus which inserts electronic memory modules into test equipment via direct horizontal insertion eliminating the need for intermediary connectors or adapters. The apparatus incorporates guide rails that maintain precise alignment of the electronic memory modules through the testing apparatus, sensors and microprocessor controlled belt apparatus to clear the automated transport paths of electronic memory module handler apparatus and automatically stacks the tested electronic memory modules.

Claims

1. An apparatus for stacking electronic memory modules, said modules having a standard notch formed into an edge at first and second ends thereof, comprising: guide rods positioned to fit into said standard notches on said edges of said electronic memory modules whereby said electronic memory modules are held in precise alignment and in a uniform stack by said guide rods during movement of said electronic memory modules along said guide rods into a position to be tested.

2. The apparatus according to claim 1, wherein said ‘structures’ guide rods are incorporated into an assembly that stacks electronic memory modules.

3. The apparatus of claim 2 wherein said assembly is formed of metal.

4. The apparatus according to claim 1, wherein said guide rods are incorporated into an assembly that holds electronic memory modules in a position to be tested.

5. The apparatus according to claim 4, wherein said guide rods are incorporated into an assembly that holds electronic memory modules in a position to be tested and has mobility to insert said electronic memory modules into a testing fixture.

6. The apparatus of claim 1 wherein said guide rods are formed of metal.

7. An apparatus for stacking electronic memory modules in a stack in stacker assembly comprising:

8. The apparatus in accordance with claim 7, wherein said positioning apparatus further comprises an alignment rod aligned adjacent to said movable flat surface that has mobility such that said alignment rod can be moved away from said movable flat surface to permit electronic memory modules to be dispensed onto said movable flat surface, and can be moved toward said movable flat surface to place said electronic memory module in a fixed position in said stacker assembly.

9. The apparatus in claim 8, wherein said alignment rod is oriented substantially perpendicular to said flat surface.

10. The apparatus in accordance with claim 7, wherein said removal device further comprises:

11. An apparatus for stacking electronic circuit modules, substantially uniform in size and shape, said circuit modules having first and second notches formed in respective first and second opposite ends of each said circuit module, comprising:

12. The apparatus of claim 11, wherein said tray assembly is removably incorporated into said apparatus for stacking said electronic circuit modules.

13. the apparatus of claim 11, wherein said tray assembly is removably incorporated into a mechanism for engaging and disengaging said electronic circuit module respectively to and from a testing position.

14. The apparatus of claim 13, wherein further said tray assembly is configured with a movable pusher assembly for inserting an individual said electronic circuit module into and retrieving said electronic circuit module from said testing position in a testing fixture.

15. The apparatus of claim 11, wherein said first and second guide rods are formed of metal.

16. The apparatus of claim 11, wherein said tray assembly is formed of metal.

17. The apparatus of claim 11, wherein said tray assembly is configured with a movable pusher assembly for inserting an individual electronic circuit module into a testing fixture having first and second guide rod segments for respectively engaging said first and second notches of said individual circuit module and enabling said movable pusher assembly to both engage and disengage said circuit module respectively into and away from a testing position in said testing fixture.

18. The apparatus of claim 11, further comprising a circuit module pusher frame disposed below and proximate said tray assembly for supporting an individual circuit module dispensed from said tray assembly, said pusher frame having first and second guide rod segments, colinear respectively with said first and second guide rods of said tray assembly when said pusher frame is in a retracted position, for engaging said first and second notches to drive said circuit module into a test fixture connector upon energizing of said pusher frame.
