Abstract

A clearing device, an operating method thereof, and a cutting device are provided. The clearing device includes: an operating platform, including an operating surface; a first clearing unit, provided on a side of the operating platform close to the operating surface; a control unit, configured to communicate with the first clearing unit and control a clearing operation and a count of the operation of the first clearing unit; at least one detecting unit, provided on the operating platform and communicatively connected to the control unit, wherein the first clearing unit is configured to clear a foreign matter on the operating surface, the detecting unit is configured to detect a degree of cleanliness of the operating surface and send to the control unit a data signal which reflects the degree of cleanliness of the operating surface.

First claim

What is claimed is:

1. A clearing device, comprising:
an operating platform, comprising an operating surface;
a first clearing unit, provided on a side of the operating platform close to the operating surface;
a control unit, configured to communicate with the first clearing unit and control a clearing operation and a count of the operation of the first clearing unit;
at least one detecting unit, provided on the operating platform and communicatively connected to the control unit,
wherein the first clearing unit is configured to clear a foreign matter on the operating surface, the detecting unit is configured to detect a degree of cleanliness of the operating surface and send to the control unit a data signal which reflects the degree of cleanliness of the operating surface.

2. The clearing device according to claim 1 , wherein
in the case where the data signal reflects that the operating surface is not clear, the control unit is configured to control the first clearing unit to clean the operating surface again; or
in the case where the data signal reflects that the operating surface is clear, the control unit is configured to control the first clearing unit to stop cleaning the operating surface.

3. The clearing device according to claim 1 , wherein the detecting unit comprises a transmitting terminal for transmitting a signal and a receiving terminal for receiving the signal, the transmitting terminal and the receiving terminal being located at two opposite sides of the operating platform respectively.

4. The clearing device according to claim 3 , wherein the signal comprises a laser or an ultrasonic wave.

5. The clearing device according to claim 1 , wherein the control unit is provided with a first threshold for limiting the count of the operation of the first clearing unit.

6. The clearing device according to claim 1 , further comprising a crushing machine provided on a side of the operating platform.

7. A cutting device, comprising a clearing device, wherein the clearing device comprises:
an operating platform, comprising an operating surface;
a first clearing unit, provided on a side of the operating platform close to the operating surface;
a control unit, configured to communicate with the first clearing unit and control a clearing operation and a count of the operation of the first clearing unit;
at least one detecting unit, provided on the operating platform and communicatively connected to the control unit,
wherein the first clearing unit is configured to clear a foreign matter on the operating surface, the detecting unit is configured to detect a degree of cleanliness of the operating surface and send to the control unit a data signal which reflects the degree of cleanliness of the operating surface.

8. The cutting apparatus according to claim 7 , wherein
in the case where the data signal reflects that the operating surface is not clear, the control unit is configured to control the first clearing unit to clean the operating surface again; or
in the case where the data signal reflects that the operating surface is clear, the control unit is configured to control the first clearing unit to stop cleaning the operating surface.

9. The cutting device according to claim 7 , wherein the detecting unit comprises a transmitting terminal for transmitting a signal and a receiving terminal for receiving the signal, the transmitting terminal and the receiving terminal being located at two opposite sides of the operating platform respectively.

10. An operating method of the clearing device according to claim 1 , comprising:
controlling the first clearing unit to perform a clearing operation once on the operating surface;
detecting the degree of cleanliness of the operating surface, and sending the detected data signal to the control unit; and
controlling the control unit to analyze the data signal, to judge whether to perform a next clearing operation.

11. The operating method of claim 10 , wherein
in the case where the control unit determines that a foreign matter exists on the operating surface, performing the next clearing operation on the operating surface and detecting the degree of cleanliness of the operating surface which has been subject to the clearing operation; or
in the case where the control unit determines that no foreign matter exists on the operating surface, ending the clearing operation of the clearing device.
