## 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

### Claim 1

A manufacturing line, comprising:
a laser system including a laser emitting device and a reflector;
a cleaning system for cleaning the reflector; and
an automatic guided vehicle for actuating the cleaning system.

### Claim 2 (depends on 1)

The manufacturing line of claim 1, wherein the cleaning system includes a cleaning device mounted to a pivotable arm.

### Claim 3 (depends on 2)

The manufacturing line of claim 2, wherein the pivotable arm is engaged by the automatic guided vehicle to sweep the cleaning device over the reflector.

### Claim 4 (depends on 2)

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

### Claim 5 (depends on 2)

The manufacturing line of claim 2, wherein the pivotable arm is coupled to a retraction device.

### Claim 6 (depends on 5)

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

### Claim 7 (depends on 5)

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

### Claim 8 (depends on 2)

The manufacturing line of claim 2, wherein the automatic guided vehicle includes a projection that engages the pivotable arm.

### Claim 9

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; and
a cleaning system for cleaning the laser system, the cleaning system being actuated by the automatic guided vehicle as the automatic guided vehicle travels along the manufacturing line past the one cell.

### Claim 10 (depends on 9)

The system of claim 9, wherein the cleaning system includes a cleaning device mounted to a pivotable arm.

### Claim 11 (depends on 10)

The system of claim 10, wherein the laser system includes a reflector, and the pivotable arm is engaged by the automatic guided vehicle to sweep the cleaning device over the reflector.

### Claim 12 (depends on 10)

The system of claim 10, wherein the cleaning device is a brush.

### Claim 13 (depends on 10)

The system of claim 10, wherein the pivotable arm is coupled to a retraction device.

### Claim 14 (depends on 13)

The system of claim 13, wherein the retraction device is a spring.

### Claim 15 (depends on 13)

The system of claim 13, wherein the retraction device is a clock spring.

### Claim 16 (depends on 10)

The system of claim 10, wherein the automatic guided vehicle includes a projection that engages the pivotable arm.

### Claim 17 (depends on 9)

The system of claim 9, wherein each cell is a location along the manufacturing line in a stamping facility.

### Claim 18 (depends on 17)

The system of claim 17, wherein at least one of the cells is a stamping press.
