Abstract

A system where a reflector of a laser alignment system is cleaned by a cleaning device that is actuated by an automatic guided vehicle as it passes the reflector. The laser alignment system is used to detect a position of the automatic guided vehicle relative to a location in a manufacturing facility. As the automatic guided vehicle passes the laser alignment system, a projection formed on the automatic guided vehicle will contact an element of a laser cleaning system to actuate the cleaning device over the reflector to clean it.

Claims (23)

1. A manufacturing line, comprising:

a laser system including a laser emitting device and a reflector;

a cleaning system for cleaning the reflector, the cleaning system including a cleaning device mounted to a pivotable arm; and

an automatic guided vehicle for actuating the cleaning system,

wherein the pivotable arm is engaged by the automatic guided vehicle to sweep the cleaning device over the reflector.

2. The manufacturing line of claim 1 , wherein the cleaning device is a brush.

3. The manufacturing line of claim 1 , wherein the pivotable arm is coupled to a retraction device.

4. The manufacturing line of claim 3 , wherein the retraction device is a spring.

5. The manufacturing line of claim 3 , wherein the retraction device is a clock spring.

6. The manufacturing line of claim 1 , wherein the automatic guided vehicle includes a projection that engages the pivotable arm.

7. A system, comprising:

a plurality of cells located along a manufacturing line;

an automatic guided vehicle for servicing the plurality of cells;

a laser system for detecting a position of the automatic guided vehicle relative to one of the cells, the laser system including a reflector; and

a cleaning system for cleaning the laser system, the cleaning system including a cleaning device mounted to a pivotable arm,

wherein the pivotable arm is engaged by the automatic guided vehicle to sweep the cleaning device over the reflector as the automatic guided vehicle travels along the manufacturing line past the one cell.

8. The system of claim 7 , wherein the cleaning device is a brush.

9. The system of claim 7 , wherein the pivotable arm is coupled to a retraction device.

10. The system of claim 9 , wherein the retraction device is a spring.

11. The system of claim 9 , wherein the retraction device is a clock spring.

12. The system of claim 7 , wherein the automatic guided vehicle includes a projection that engages the pivotable arm.

13. The system of claim 7 , wherein each cell is a location along the manufacturing line in a stamping facility.

14. The system of claim 13 , wherein at least one of the cells is a stamping press.
