a sweeping module, comprising a brush component and a steam generating component, arranged in sequence in a cleaning direction of the cleaning device;
a washing module, configured to wash a part to be cleaned, wherein the washing module and the sweeping module are arranged in sequence in the cleaning direction of the cleaning device, and
a cleaning fluid supply module which comprises a liquid vessel and a pipeline, the pipeline is communicated with the sweeping module and the washing module respectively,
wherein in a direction of movement of the part to be cleaned, the washing module comprises a first cleaning portion, a second cleaning portion and a final cleaning portion arranged in sequence, the liquid vessel comprises a first liquid vessel and a second liquid vessel separated from each other, a liquid outlet of the first liquid vessel is communicated with the final cleaning portion, a liquid outlet of the second liquid vessel is communicated with the first cleaning portion and the second cleaning portion respectively, the liquid outlet of the first cleaning portion, the liquid outlet of the second cleaning portion and a liquid outlet of the final cleaning portion are communicated with a liquid return port of the second liquid vessel respectively.

2. The cleaning device according to claim 1 , wherein the brush component comprises a brush, an actuator, a pressure sensor and a controller, a cleaning face of the brush is disposed towards and parallel to the part to be cleaned; the actuator is configured to drive the brush to move; the pressure sensor is configured to measure a pressure of the cleaning face of the brush, and transmit a pressure signal to the controller; the controller is electrically connected to the actuator and the pressure sensor respectively; the controller is configured to receive the pressure signal from the pressure sensor, and generate a control signal according to the pressure signal for transmitting to the actuator.

3. The cleaning device according to claim 2 , wherein the brush is a plate-type brush and comprises a plate body part and a brush part, the plate part comprises a first surface which is parallel to the cleaning face, the brush part is disposed on the first surface, and an extend direction of a brushing of the brush part is perpendicular to the first surface; the plate body part is connected with the actuator.

4. The cleaning device according to claim 1 , wherein the steam generating component comprises a steam generator and a steam ejector, a steam generated by the steam generator is sprayed by the steam ejector to a surface to be cleaned of the part to be cleaned.

5. The cleaning device according to claim 4 , wherein a temperature of the steam is greater than 90° C.

6. The cleaning device according to claim 1 , wherein the cleaning fluid supply module further comprises a heating device, which is configured to heat the cleaning fluid and disposed on the pipeline, and/or in the liquid vessel.

7. The cleaning device according to claim 6 , wherein a temperature of the cleaning fluid after being heated by the heating device is about 40° C. to 50° C.

8. The cleaning device according to claim 1 , further comprising a camera device, an air knife unit and an optical detection device, the camera device, the sweeping module, the washing module, the air knife unit and the optical detection device are sequentially arranged in the cleaning direction in sequence.

9. A cleaning method, wherein the cleaning method uses the cleaning device according to claim 1 for cleaning, the cleaning method comprises the following steps:
generating steam by the steam generating component to act on the part to be cleaned;
sweeping one surface of the part to be cleaned by the brush component;
after the one surface is swept, then sweeping the other surface, which is opposite to the one surface; and
washing the part to be cleaned after being swept with the washing module.

10. The cleaning method according to claim 9 , wherein the steam generating component comprises a steam generator and a steam ejector, the step of generating steam by the steam generating component to act on the part to be cleaned comprises:
heating cleaning fluid from liquid into steam by the steam generator, and spraying the steam on the part to be cleaned by the steam ejector.

11. The cleaning method according to claim 9 , wherein the cleaning device further comprises a cleaning fluid supply module which is configured to transport cleaning fluid to the sweeping module and the washing module, the cleaning fluid module comprises a heating device, before the step of washing the part to be cleaned after being swept with the washing module, heating the cleaning fluid by the heating device.

12. The cleaning method according to claim 9 , wherein the part to be cleaned is a display panel.
