Abstract

The invention provides a simple, accurate, low-cost, and repeatable method for using an illumination device (110) to facilitate the alignment of two components (120, 160) during an assembly process. A laser mount positioning device (LMPD) (130) provides an apparatus for holding an illumination device (110) and positioning that illumination device such that the light beam (180) from the illumination device is passed through a guide pin hole (136). The light beam illuminates a guide pin (150) on another component when the two components are aligned properly. The LMPD (130) is installed in the guide pin hole in a preferred embodiment.

Claims

1. A laser mount positioning device (LMPD) for supporting and positioning an illumination device used for aligning a first component having a guide pin hole and a second component having a guide pin during an assembly process in which said guide pin is inserted into said guide pin hole, said LMPD comprising:

a block of material including at least one attachment means comprising a shaped projection formed at a first end of said block of material;

at least one illumination device holder comprising a cylindrical channel within said block of material for supporting and positioning said illumination device; and

a guide pin receiving means comprising a counter bore centrally located in said at least one attachment means, said guide pin receiving means being coupled to said at least one illumination device holder, and being oriented with respect to said at least one illumination device holder, such that when said LMPD is coupled to said first component, and when said illumination device is inserted in said at least one illumination device holder, a light beam from said illumination device is allowed to pass through said guide pin receiving means, through said at least one attachment means, and through said guide pin hole of said first component, said light beam thereby illuminating said guide pin on said second component when said first component and said second component are aligned.

2. The LMPD as claimed in claim 1, wherein said LMPD further comprises at least one illumination device.

3. The LMPD as claimed in claim 2, wherein said at least one illumination device comprises a shaped beam light source.

4. The LMPD as claimed in claim 2, wherein said at least one illumination device comprises at least one laser light pointing device.

5. The LMPD as claimed in claim 1, wherein said at least one illumination device holder is created using a machining process.

6. The LMPD as claimed in claim 1, wherein said shaped projection is shaped to conform to said guide pin hole and to allow said block of material to be detachably coupled to said first component.

7. The LMPD as claimed in claim 6, wherein said shaped projection is cylindrically shaped.

8. The LMPD as claimed in claim 1, wherein said counter bore has a shape which conforms to the tip of said guide pin.

9. The LMPD as claimed in claim 1, wherein said LMPD further comprises at least one set of mounting hardware.

10. The LMPD as claimed in claim 1, wherein said block of material comprises at least one plastic material.

11. The LMPD as claimed in claim 1, wherein said block of material comprises at least one metallic material.

12. The LMPD as claimed in claim 1, wherein said LMPD further comprises a light passage for coupling said at least one illumination device holder to said guide pin receiving means.

13. The LMPD as claimed in claim 1, wherein said block of material has a substantially rectangular shape.

14. The LMPD as claimed in claim 1, wherein said block of material has a substantially cylindrical shape.

15. The LMPD as claimed in claim 1, wherein said block of material comprises at least one transparent material.

16. A method of using a laser mount positioning device (LMPD) in an assembly process wherein a first component having at least one guide pin hole and a second component having at least one guide pin are mated together and wherein said at least one guide pin and said at least one guide pin hole are used for aligning and mating said first and second components, said method comprising the steps of:

coupling said LMPD to said first component, said LMPD having an attachment means and said LMPD being detachably coupled to said first component by inserting said attachment means into a guide pin hole in said first component;

mounting an illumination device to said LMPD, said LMPD having an illumination device holder for holding said illumination device;

directing a light beam, being emitted from said illumination device, from said LMPD and through a center portion of said guide pin hole; and

aligning said first component with said second component using said light beam, wherein correct alignment occurs when said light beam illuminates a tip of a guide pin on said second component.

17. The method as claimed in claim 16, further including a step of:

mounting said illumination device such that said light beam is centered in said guide pin hole.

18. The method as claimed in claim 16, wherein said method further comprises the step of:

maintaining said correct alignment while mating said first component with said second component, said mating occurring by positioning said two components closer to each other such that said tip of said guide pin on said second component is inserted into said guide pin hole on said first component and inserted into a guide pin receiving means of said LMPD, said guide pin receiving means being coupled to said attachment means.

19. The method as claimed in claim 18, wherein said method further comprises the step of:

continuing said mating process by positioning said two components closer together until said guide pin is inserted into said guide pin hole and said LMPD is uncoupled from said first component, wherein said LMPD is uncoupled from s aid first component by said guide pin forcing said attachment means out of said guide pin hole as said two components are moved closer together.

20. The method as claimed in claim 16, said method further comprising the steps of:

coupling a second LMPD to said first component, wherein a second guide pin hole of said at least one guide pin hole is used for said coupling and said second LMDP comprising a laser light source, so that a second light beam being emitted from said second LMPD passes through a center portion of said second guide pin hole; and

aligning said first component with said second component using said light beam to illuminate said guide pin on said second component and using said second light beam to illuminate a second guide pin on said second component.
