Abstract

A cleaning system comprises a first cleaning tank, a carrying and moving unit, a first cleaning spray head, and a rolling brush unit. The carrying and moving unit is configured to move a polishing film to be cleaned into the first cleaning tank and hold the polishing film in the first cleaning tank. The first cleaning spray head is configured to spray a cleaning liquid on the polishing film held in the first cleaning tank. The rolling brush unit is configured to brush the polishing film while the first cleaning spray head sprays the cleaning liquid on the polishing film.

First claim

What is claimed is:

1. A cleaning system, comprising:
a first cleaning tank;
a carrying and moving unit including a lifting mechanism, a driver of the lifting mechanism configured to lower a polishing film to be cleaned into the first cleaning tank and hold the polishing film in the first cleaning tank during cleaning;
a first cleaning spray head configured to spray a cleaning liquid on the polishing film held in the first cleaning tank; and
a rolling brush unit configured to brush the polishing film while the first cleaning spray head sprays the cleaning liquid on the polishing film, the rolling brush unit comprising a horizontal moving mechanism including:
a horizontal moving driver; and
a horizontal moving table slidably mounted on a horizontal rail, wherein the horizontal moving driver is configured to drive the horizontal moving table to move fore and aft in a horizontal direction along the horizontal rail.

2. The cleaning system of claim 1 , wherein the carrying and moving unit further comprises:
a carrying table on which the polishing film is disposed; and
a support frame configured to support the lifting mechanism and the carrying table.

3. The cleaning system of claim 2 , wherein the carrying and moving unit comprises a sensor adapted to detect whether the polishing film is on the carrying table and to detect a state of the polishing film on the carrying table.

4. The cleaning system of claim 3 , wherein the lifting mechanism is mounted on the support frame.

5. The cleaning system of claim 4 , wherein the carrying table is mounted on the lifting mechanism and configured to move up and down with the lifting mechanism along a vertical direction.

6. The cleaning system of claim 5 , wherein the sensor is mounted on the lifting mechanism.

7. The cleaning system of claim 6 , wherein the lifting mechanism comprises an installation frame on which the carrying table and the sensor are mounted, and wherein the driver of the lifting mechanism is mounted on the support frame and adapted to drive the installation frame to move up and down in the vertical direction.

8. The cleaning system of claim 1 , wherein the rolling brush unit further comprises:
a rolling brush installation frame;
a rolling brush rotatably mounted on the rolling brush installation frame;
a rolling brush driver adapted to drive the rolling brush to rotate about an axis of the rolling brush;
a vertical moving mechanism including a vertical moving driver and configured to move the rolling brush up and down in the vertical direction; and
a main support frame configured to support the rolling brush, the rolling brush driver, the horizontal moving mechanism, and the vertical moving mechanism.

9. The cleaning system of claim 8 , wherein the vertical moving driver is mounted on the horizontal moving table and configured to move fore and aft along the horizontal rail with the horizontal moving table, and the vertical moving mechanism further comprises a vertical connecting shaft connecting the rolling brush installation frame to the vertical moving driver.

10. The cleaning system of claim 9 , wherein the vertical moving driver is adapted to move the rolling brush installation frame up and down in the vertical direction via the vertical connecting shaft.

11. The cleaning system of claim 10 , wherein the rolling brush driver is configured to drive the rolling brush to rotate about the axis of the rolling brush with a second belt transmission mechanism.

12. The cleaning system of claim 11 , further comprising a pair of protection plates mounted to the rolling brush installation frame, one of the pair of protection plates is disposed at each of a front side and a rear side of the rolling brush.

13. The cleaning system of claim 8 , further comprising a second cleaning tank, the rolling brush is moved into the second cleaning tank by the horizontal moving mechanism and the vertical moving mechanism.

14. The cleaning system of claim 13 , further comprising a second cleaning spray head mounted in the second cleaning tank, the second cleaning spray head configured to spray the cleaning liquid on the rolling brush held in the second cleaning tank.

15. The cleaning system of claim 14 , wherein the second cleaning tank has a second drain outlet in a bottom of the second cleaning tank.

16. The cleaning system of claim 1 , wherein the horizontal moving driver is configured to drive the horizontal moving table to move fore and aft along the horizontal rail with a first belt transmission mechanism.

17. The cleaning system of claim 1 , further comprising a gas spray head adapted to spray a gas on the polishing film to dry the polishing film.

18. The cleaning system of claim 17 , wherein the first cleaning spray head and the gas spray head are mounted to an interior wall of the first cleaning tank.

19. The cleaning system of claim 1 , wherein the first cleaning tank has a first drain outlet in a bottom of the first cleaning tank.

20. A cleaning system, comprising:
a first cleaning tank;
a carrying and moving unit including a lifting mechanism, a driver of the lifting mechanism configured to lower a polishing film to be cleaned into the first cleaning tank and hold the polishing film in the first cleaning tank during cleaning;
a first cleaning spray head configured to spray a cleaning liquid on the polishing film held in the first cleaning tank; and
a rolling brush unit configured to brush the polishing film while the first cleaning spray head sprays the cleaning liquid on the polishing film, the rolling brush unit comprising:
a horizontal moving mechanism including a horizontal moving table and a horizontal moving driver for driving the horizontal moving table to move fore and aft in a horizontal direction relative to the polishing film; and
a vertical moving mechanism including a vertical moving driver mounted on the horizontal moving table and configured to move fore and aft along with the horizontal moving table, and to move the rolling brush up and down in the vertical direction.
