Abstract

The present invention relates to a base station for a cleaning robot to park in, where the cleaning robot includes a wiping board, and a flexible wiping member replaceably butts the wiping board to form a wiping surface to wipe a working surface on which the cleaning robot walks, where the base station includes: a storage module, configured to store a continuous wiping base material; and a feeding module, configured to drive a free end of the wiping base material to be conveyed to a cutting position, to cause the free end to be cut from the wiping base material to form the wiping member. The present invention has the following beneficial effects: After returning to the base station, the cleaning robot may automatically mount a wiping member without intervention by a user.

3 . The system of claim 1 , wherein the wiping member separating position ( 217 , 4221 ) is higher than the wiping board separating position ( 2021 ) and a space is formed between the wiping member separating position ( 217 , 4221 ) and the wiping board separating position ( 2021 ), for the cleaning robot ( 100 ) to park in.

4 . The system of claim 1 , wherein after the wiping board ( 122 , 1201 ) and the cleaning robot ( 100 ) are separated, the driving module ( 207 , 205 , 412 ) is configured to move the wiping board ( 122 , 1201 ) from the wiping board separating position ( 2021 ) to the wiping member separating position ( 217 , 4221 ).

5 . The system of claim 1 , wherein the base station further comprises: a separating module ( 422 ), at the wiping member separating position ( 217 , 4221 ), configured to act on the wiping board ( 122 , 1201 ) and/or the wiping member, to separate the wiping member from the wiping board ( 122 , 1201 ).

6 . The system of claim 5 , wherein the base station ( 200 ) comprises: a recycling box ( 206 ) configured to receive a wiping member separated from the wiping board ( 122 , 1201 ).

7 . The automatic cleaning system of claim 6 , wherein the separating module ( 422 ) is disposed at the opening of the recycling box ( 211 , 15 , 206 ) and comprises a barb-shaped structure configured to hook the wiping member and take down the wiping member from the wiping board ( 122 , 1201 ).

8 . The automatic cleaning system of claim 6 , wherein the separating module ( 422 ) is disposed in the opening of the recycling box ( 206 ), and when the wiping board passes through the separating module ( 422 ), the wiping member on the wiping board ( 122 , 1201 ) is hooked and scraped off.

9 . The automatic cleaning system of claim 1 , wherein the system further comprises: a operating module ( 125 , 400 ), at a wiping member mounting position ( 215 , 420 ), configured to act on the wiping board ( 122 , 1201 ) and/or a replacement wiping member to mount the replacement wiping member to the wiping board ( 122 , 1201 ), wherein the wiping member mounting position ( 215 , 420 ) is different from the wiping member separating position ( 217 , 4221 ).

10 . The automatic cleaning system of claim 9 , wherein the driving module ( 207 , 205 , 412 ) is configured to move the separated wiping board ( 122 , 1201 ) from the wiping member separating position ( 217 , 4221 ) to the wiping member mounting position ( 215 , 420 ), to cause the operating module to mount the replacement wiping member to the wiping board ( 122 , 1201 ).

11 . The automatic cleaning system of claim 10 , wherein the system is configured to mount the wiping board ( 122 , 1201 ) equipped with a replacement wiping member on the main body ( 101 ) at a wiping board mounting position ( 2022 ); and

the driving module ( 207 , 205 , 412 ) is configured to move the wiping board ( 122 , 1201 ) equipped with the replacement wiping member from the wiping member mounting position ( 217 , 4221 ) to the wiping board mounting position ( 2022 ).

12 . The automatic cleaning system of claim 9 , wherein the operating module ( 125 , 400 ) is mounted on the base station ( 200 ).

13 . The automatic cleaning system of claim 1 , wherein when the cleaning robot ( 100 ) returns to the base station ( 200 ), the cleaning robot ( 100 ) is configured to separate the wiping board ( 122 , 1201 ) equipped with the wiping member and the main body ( 101 ).

14 . A control method for controlling an automatic cleaning system, the method comprising:
