Tool for applying a protective film to a lens of a LIDAR sensor
A tool for applying a protective film to a lens of a light detection and ranging (LIDAR) sensor is disclosed. The tool includes at least one cover, a film spindle, a film roller, and a pivot bar. The at least one cover has an elongated shape with a first end and a second end opposite of the first end. The film spindle is mounted to the at least one cover adjacent to the second end thereof. The film spindle is configured to hold a roll of the protective film. The film roller is mounted to the at least one cover adjacent to the first end thereof. The film roller is configured to apply the protective film onto the lens. The pivot bar has a first end configured to be pivotally attached to the LIDAR sensor and a second end pivotally attached to the at least one cover.
1. A tool for applying a protective film to a lens extending around a perimeter surface of a light detection and ranging (LIDAR) sensor having a cylindrical body, the tool comprising:
at least one cover having an elongated shape with a first end and a second end opposite of the first end;
a film spindle mounted to the at least one cover adjacent to the second end thereof, wherein the film spindle is configured to hold a roll of the protective film;
a film roller mounted to the at least one cover adjacent to the first end thereof, the film roller being configured to apply the protective film onto the lens; and
a pivot bar having a first end configured to be pivotally attached to the LIDAR sensor and a second end pivotally attached to the at least one cover.
2. The tool of claim 1 wherein the pivot bar has a length that is adjustable to adjust a distance between the second end of the pivot bar and the perimeter surface of the LIDAR sensor.
3. The tool of claim 1 further comprising a torsion device configured to apply a torsional force to the at least one cover to bias the film roller against the perimeter surface of the LIDAR sensor.
4. The tool of claim 1 further comprising an electric motor operable to rotate the film roller relative to the at least one cover and thereby rotate the tool around the perimeter surface of the LIDAR sensor to apply the protective film onto the lens.
5. The tool of claim 1 further comprising a paddle pivotally attached to the at least one cover and configured to apply pressure to the perimeter surface of the LIDAR sensor to eliminate wrinkles in the protective film.
6. The tool of claim 1 further comprising a lens cleaning device pivotally attached to the at least one cover and configured to clean the perimeter surface of the LIDAR sensor before the film roller applies the protective film to the lens.
7. The tool of claim 1 further comprising an ultraviolet (UV) adhesive cure lamp pivotally attached to the at least one cover and configured to cure UV adhesive disposed between the protective film and the perimeter surface of the LIDAR sensor.
8. The tool of claim 1 further comprising a film cutter pivotally attached to the at least one cover and configured to cut the protective film.
9. The tool of claim 8 further comprising:
a position sensor configured to measure a rotational position of the film roller; and
a control module configured to actuate the film cutter to cut the protective film based on the rotational position of the film roller.
10. The tool of claim 1 further comprising a UV adhesive dispenser pivotally attached to the at least one cover and configured to apply a UV adhesive to the perimeter surface of the LIDAR sensor.
11. The tool of claim 1 wherein the at least one cover includes a top cover and a bottom cover, and the tool further comprises a stanchion extending between the top and bottom covers and rigidly connecting the top and bottom covers to one another.
12. A tool for applying a protective film to a lens extending around a perimeter surface of a LIDAR sensor having a cylindrical body, the tool comprising:
a top cover;
a bottom cover, each of the top and bottom covers having an elongated shape with a first end and a second end opposite of the first end;
a film spindle disposed between the top and bottom covers and mounted to at least one of the top and bottom covers adjacent to the second end thereof, wherein the film spindle is configured to hold a roll of the protective film;
a film roller disposed between the top and bottom covers and mounted to at least one of the top and bottom covers adjacent to the first end thereof, the film roller being configured to apply the protective film onto the lens;
a pivot bar having a first end configured to be pivotally attached to the LIDAR sensor, a second end pivotally attached to at least one of the top and bottom covers, and an adjustable length extending between the first and second ends;
a torsion device configured to apply a torsional force to at least one of the top and bottom covers to bias the film roller against the perimeter surface of the LIDAR sensor;
a paddle pivotally attached to at least one of the top and bottom covers and configured to apply pressure to the perimeter surface of the LIDAR sensor to eliminate wrinkles in the protective film;
a lens cleaning device pivotally attached to at least one of the top and bottom covers and configured to clean the perimeter surface of the LIDAR sensor before the film roller applies the protective film to the lens; and
a UV adhesive cure lamp pivotally attached to at least one of the top and bottom covers and configured to cure UV adhesive disposed between the protective film and the perimeter surface of the LIDAR sensor.
13. The tool of claim 12 further comprising an electric motor operable to rotate the film roller relative to the top and bottom covers and thereby rotate the tool around the perimeter surface of the LIDAR sensor.
14. The tool of claim 12 wherein:
the lens cleaning device is configured to engage the perimeter surface of the LIDAR sensor at a first angular position;
the paddle is configured to engage the perimeter surface of the LIDAR sensor at a second angular position; and
the film roller is configured to engage the perimeter surface of the LIDAR sensor at a third angular position located between the first and second angular positions.
