The water pump inside the liquid storage box will send the cleaning liquid to the cloth belt along the liquid storage block, making it easier for the cloth belt to wipe and adhere to the dirt on the surface of the magnetic sheet. The rotation of the cleaning belt will push the dirt and magnetic chips on both sides of the magnetic sheet to the suction nozzle, and squeeze the magnetic sheet to the rotating wheel. The inside of the suction nozzle forms a negative pressure under the action of the negative pressure fan. The setting of the air permeable groove inside the roller makes it easier for the cloth belt to ventilate, so that the dirt, magnetic chips and sewage inside the cloth belt are all sucked away along the suction nozzle, so that the cloth belt cleans itself while wiping, and the rotating wheel will rotate under the drive of the micro motor and the transmission disk, so that the rotating wheel drives the magnetic sheet in contact with it to rotate together, which is convenient for the suction nozzle to absorb the dirt, and The rubber sheet extending from the inside of the groove will contact the side wall of the magnetic sheet. When the rotating wheel drives the magnetic sheet to rotate, the outer rubber sheet will be stretched due to the friction with the magnetic sheet, and will shrink and reset when it is separated from the magnetic sheet under the rotation of the rotating wheel, so as to take out the magnetic chips and dirt on the surface of the magnetic sheet, so that the movable baffle can absorb the dirt on the side of the magnetic sheet. Moreover, due to the setting of the arc cover, the dirt on the rubber sheet, the surface of the rotating wheel and the inside of the groove can be adsorbed and collected. Moreover, due to the setting of the movable baffle, when negative pressure is formed inside the arc cover, there is a certain gap between the arc cover and the rotating wheel, and the movable baffle forms a structure similar to a one-way valve. The external airflow will push the movable baffle open along the air channel and enter the inner side of the arc cover. The flow of airflow can not only promote the dirt on the surface of the rotating wheel and the rubber sheet to be adsorbed along the ventilation pipe, but also help the rotating wheel to rotate under the impetus of the airflow, thereby promoting the whole cleaning process. After cleaning is completed, the first telescopic rod continues to extend, so that the rotating wheel continues to push against the magnetic sheet, pushing the magnetic sheet from between the two cleaning belts to between the two feeding belts. At the same time, the hollow arc block drives the limit rod and the top block to move along the slide rail, so that the top block contacts the upper fixed plate on the cleaning belt, allowing the two cleaning belts to move away from each other under the contact, so as to facilitate the pushing of the magnetic sheet, and finally it is sent to the inside of the feeding slide under the clamping of the two feeding belts.

[0013] Compared with the existing technology, the present invention has the following beneficial effects: 1. The water pump inside the liquid storage box sends the cleaning liquid to the cloth belt along the liquid storage block, making it easier for the cloth belt to wipe and adhere to the dirt on the surface of the magnetic sheet. The rotation of the cleaning belt pushes the dirt and magnetic chips on both sides of the magnetic sheet to the suction nozzle, and squeezes the magnetic sheet to the rotating wheel. The inside of the suction nozzle forms a negative pressure under the action of the negative pressure fan. The setting of the air permeable groove inside the roller makes it easier for the cloth belt to ventilate, so that the dirt, magnetic chips and sewage inside the cloth belt are all sucked away along the suction nozzle, so that the cloth belt cleans itself while wiping, ensuring the cleaning effect; 2. The rotating wheel will rotate under the promotion of the micro motor and the transmission disk, so that the rotating wheel drives the magnetic sheet in contact with it to rotate together, which is convenient for the suction nozzle to absorb dirt, and the rubber sheet extending from the inside of the groove will contact the side wall of the magnetic sheet. When the rotating wheel drives the magnetic sheet to rotate, the external rubber sheet will be stretched under the friction with the magnetic sheet, and will shrink and reset when it is separated from the magnetic sheet under the rotation of the rotating wheel, bringing out the magnetic chips and dirt on the surface of the magnetic sheet, making it convenient for the movable baffle to absorb the dirt on the side of the magnetic sheet, further promoting the cleaning effect; 3. Due to the setting of the arc cover, the dirt on the rubber sheet, the surface of the runner and the inside of the groove can be adsorbed and collected. Moreover, due to the setting of the movable baffle, when negative pressure is formed inside the arc cover, there is a certain gap between the arc cover and the runner, and the movable baffle forms a structure similar to a one-way valve. The external airflow will push the movable baffle open along the air channel and enter the inner side of the arc cover. The flow of air can not only promote the dirt on the runner surface and the rubber sheet to be adsorbed along the ventilation pipe, but also help the runner to rotate under the impetus of the airflow, thereby promoting the entire cleaning process; 4. Through the magnetic separation structure of the present invention, the whole is controlled by program automation. After the magnetic performance standard is set, the magnetic sheets that meet the requirements and those that do not meet the requirements can be automatically distinguished, which reduces labor costs and improves the efficiency and accuracy of selection.

[0014] In summary, the present invention cleans the magnetic sheets when they are loaded, which not only ensures that the produced magnetic sheets have a good appearance, but also that the magnetic sheets are cleaned during sorting, so there will be no debris interfering with the detection results, thereby ensuring the accuracy of the detection.

8. The method for using the automatic cleaning device of the NdFeB permanent magnet magnetic sheet sorting machine according to claim 1, characterized in that: The method of use uses an automatic cleaning device for a NdFeB permanent magnet magnetic sheet sorting machine as described in any one of claims 1 to 7, and specifically comprises the following steps: First, the magnetic sheets (43) adsorbed together are placed inside the discharge barrel (6), and the bottom magnetic sheet (43) contacts the cushion block. By extending the first telescopic rod (8), the rotating wheel (11) supports the bottom magnetic sheet (43) and pushes it between the two cleaning belts (4). The water pump inside the liquid storage box (27) sends the cleaning liquid along the liquid storage block (25) to the cloth belt (23), making it easier for the cloth belt (23) to wipe and adhere to the dirt on the surface of the magnetic sheet (43). The rotation of the cleaning belt (4) pushes the dirt and magnetic chips on both sides of the magnetic sheet (43) to the dirt suction nozzle (28), and the magnetic sheet (43) is moved to the cleaning belt (28). The roller (21) is provided with a ventilation groove (24) inside the roller (21), which facilitates the ventilation of the cloth belt (23), so that the dirt, magnetic chips and sewage inside the cloth belt (23) are all sucked away along the suction nozzle (28), so that the cloth belt (23) is self-cleaning while wiping, and the roller (11) is driven by the micro motor (12) and the transmission disk (13) to rotate, so that the roller (11) drives the magnetic sheet (43) in contact with it to rotate together, so that the suction nozzle (28) can absorb the dirt. The magnetic sheet (43) is provided with a rubber sheet (19) extending from the inside of the groove (16) and in contact with the side wall of the magnetic sheet (43). When the rotating wheel (11) drives the magnetic sheet (43) to rotate, the outer rubber sheet (19) is stretched due to the friction with the magnetic sheet (43). When the rotating wheel (11) is detached from the magnetic sheet (43), the rubber sheet (19) is retracted and reset, thereby taking away the magnetic chips and dirt on the surface of the magnetic sheet (43). This makes it easier for the movable baffle (18) to absorb dirt on the side of the magnetic sheet (43). In addition, due to the arrangement of the arc-shaped cover (15), dirt on the rubber sheet (19), the surface of the rotating wheel (11) and the inside of the groove (16) can be absorbed and collected. Moreover, due to the provision of the movable baffle (18), when negative pressure is formed inside the arc-shaped cover (15), since there is a certain gap between the arc-shaped cover (15) and the rotating wheel (11), and the movable baffle (18) forms a structure similar to a one-way valve, the external airflow will push the movable baffle (18) along the air channel (17) and then enter the inner side of the arc-shaped cover (15). The flow of the airflow can not only promote the dirt on the surface of the rotating wheel (11) and the rubber sheet (19) to be adsorbed along the ventilation pipe (14), but also help the rotating wheel (11) to rotate under the impetus of the airflow, thereby promoting the entire cleaning process; After cleaning is completed, the first telescopic rod (8) continues to extend, so that the rotating wheel (11) continues to push against the magnetic sheet (43), pushing the magnetic sheet (43) from between the two cleaning belts (4) to between the two feeding belts (5). At the same time, the hollow arc block (9) drives the limit rod (37) and the top block (38) to move along the slide rail (36), so that the top block (38) contacts the upper fixed plate (32) on the cleaning belt (4), allowing the two cleaning belts (4) to move away from each other under the contact, so as to facilitate the pushing of the magnetic sheet (43), and finally sent to the inside of the feeding slide (3) under the clamping of the two feeding belts (5). After completing one process, the first telescopic rod (8) retracts and resets.
