Abstract

An improved method and apparatus for controlling a laser projection assisted assembly operation includes the ability to display a menu with the laser projector. An operator is able to request the menu be displayed at the operator'"'"'s location. The menu provides the operator the ability to select from several display options. By selecting an icon associated with a desired display option, the operator is able to change the display option at a location remote from the control. This is particularly valuable in large laser assisted work assemblies.

Claims

1. A laser projection assembly system comprising:

a laser projector;

a computer for controlling the laser projector, said computer controlling the laser projector to generate laser scanned images including a plurality of parts to be assembled, said computer controls said laser projector to project upon a surface an image of a menu representing a plurality of options for the computer to control the laser projector.

2. The laser projection assembly system according to claim 1 wherein said plurality of options comprises a plurality of display options.

3. The laser projection assembly system according to claim 2 wherein the images of the parts to be assembled are boards and connection plates.

4. The laser projection assembly system according to claim 2 wherein the display options include at least two of the following:

displaying only connection plates, displaying the connection plates at an up location, displaying only the boards, displaying the boards at an up location, displaying both boards and connecting plates, and displaying both boards and connection plates at an up location.

5. The laser projection system according to claim 4 wherein the laser projector includes a reflection sensor which receives and detects a reflected beam indicating a selection of one of the options in the menu.

6. The laser projection assembly system of claim 1 wherein the laser projector projects the menu representing the plurality of options.

7. A method for displaying the image of workpieces to be assembled including the steps of:

(a) projecting an image of a workpiece to be assembled onto a work surface;

(b) displaying a menu of options on the work surface;

(c) selecting one of the options displayed in said step (b);

(d) altering the image in said step (a) based upon said step (c).

8. A method of claim 7 wherein said step (c) is performed by receiving a reflected beam from the projected laser beam.

9. The method of claim 7 wherein the image includes boards and connection plates.

10. The method of claim 9 wherein the options include at least two of the following:

displaying only connection plates, displaying the connection plates at an up location, displaying only the boards, displaying the boards at an up location, displaying both boards and connecting plates, and displaying both boards and connection plates at an up location.

11. A method for displaying the image of workpieces to be assembled including the steps of:

(a) projecting an image of a workpiece to be assembled onto a work surface;

(b) displaying a menu of options;

(c) selecting one of the options displayed in said step (b), by receiving a reflection;

(d) altering the image in said step (a) based upon said step (c).

12. A method of claim 11 wherein said step (c) is performed by receiving a reflected beam from the projected laser beam.
