[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] like Figure 1-4 As shown, a surface cleaning tool for a test disk comprises a mounting frame 1, a brush wheel 2 and a test disk 8 slidably mounted on the mounting frame 1, a lifting cover 3 is movably mounted on one side of the mounting frame 1, the cover opening of the lifting cover 3 faces the upper surface of the mounting frame 1 and is slidably connected to the opening of the test disk 8, after the test disk 8 moves to the bottom of the lifting cover 3, the lifting cover 3 is lowered to cover the opening of the test disk 8, so that the groove on the surface of the test disk 8 is in the lifting cover 3, ensuring that the dust generated when cleaning the notch of the test disk 8 will not be scattered, a lifting frame 10 is rotatably connected in the lifting cover 3, the brush handle of the brush wheel 2 is plugged into the bottom surface of the lifting frame 10, and an exhaust fan 5 is fixedly connected to the top surface of the lifting cover 3, the air outlet of the exhaust fan 5 is located outside the lifting cover 3, and the exhaust fan 5 A filter tube 4 is installed at the air outlet, and a plurality of air inlet pipes 9 distributed in a circular array are fixedly connected to the outer surface of the lifting cover 3. One end of the air inlet pipe 9 extends to the brush wheel 2. After the lifting cover 3 covers the test disk 8, the bristles of the brush wheel 2 arranged inside it will enter the slot of the test disk 8, and the brush wheel 2 is driven to rotate by the rotation of the lifting frame 10 to achieve dust cleaning of the slot of the test disk 8. In addition, during the cleaning process, the exhaust fan 5 is started to extract the flying dust in the lifting cover 3, and the plurality of air inlet pipes 9 are set as the air inlet of the exhaust fan 5. Because they are distributed in a ring shape in the lifting cover 3, uniform air intake in the lifting cover 3 can be guaranteed, thereby ensuring that the flying dust in the lifting cover 3 enters the filter tube 4 through the exhaust fan 5 for collection and filtration.

[0026] In order to drive the test disk 8 to move: a slider 15 for placing the test disk 8 is embedded in the upper surface of the mounting frame 1 and is slidably connected, and two sprockets 13 driven by a chain are rotatably connected to the lower surface of the mounting frame 1. The two sprockets 13 are respectively installed on both sides of the mounting frame 1, and the bottom edge of the slider 15 is fixedly connected to the chain between the two sprockets 13. One of the sprockets 13 is driven to rotate by installing a motor on the mounting frame 1, and the chain movement between the two is realized with the assistance of the other sprocket 13, and the slider 15 will drive the test disk 8 to slide and move on the mounting frame 1 as the chain moves.

[0027] In order to install the lifting cover 3: a servo motor 6 is fixedly connected to the outer top surface of the lifting cover 3, the main shaft of the servo motor 6 extends into the lifting cover 3 and is fixedly connected to the top edge of the lifting frame 10, and a vertically distributed electric telescopic rod 7 is fixedly connected between the casing of the servo motor 6 and the mounting frame 1, the lifting frame 10 is driven to rotate by the servo motor 6, and the servo motor 6 can drive the lifting cover 3 connected thereto to rise and fall by extending and retracting the electric telescopic rod 7.

[0028] In order to further clean the dust on the brush wheel 2: the end face of the brush handle of the brush wheel 2 is integrally formed with a plurality of protrusions inserted into the lifting frame 10, and a spring 14 is fixedly connected between the protrusion of the brush wheel 2 and the lifting frame 10, and a plurality of vibration motors 11 are fixedly connected to the end face of the brush handle of the brush wheel 2, and an electric push rod 12 is movably connected between the brush handle of the brush wheel 2 and the lifting frame 10. As shown in the figure, the spring 14 is in a contracted state in a normal state, that is, the brush handle of the brush wheel 2 is ensured to be in a plugged state with the lifting frame 10, so that the brush wheel 2 can rotate with the rotation of the lifting frame 10. The electric push rod 12 is fixed on the lifting frame 10, and the telescopic end part is against the brush handle of the brush wheel 2. Therefore, the electric push rod 12 is extended to push the brush wheel 2 down to leave the lifting frame 10, and the spring 14 is forced to elastically stretch during the descent. At this time, the vibration of the brush wheel 2 can be achieved by vibrating a plurality of vibration motors 11, so that the dust on the bristles of the brush wheel 2 can fall off and be extracted cleanly under the action of the exhaust fan 5. Therefore, the spring rod 14 is arranged in this scheme to prevent the lifting frame 10 from vibrating when the brush wheel 2 vibrates.

[0029] The working principle is to use the chain between the two sprocket wheels 13 to realize the slider 15 to drive the test disk 8 to move to the position just below the lifting cover 3, and then use the electric telescopic rod 7 to extend to realize the servo motor 6 to drive the lifting cover 3 to descend to cover the test disk 8, and use the servo motor 6 to drive the lifting frame 10 to drive the brush wheel 2 to rotate, so as to clean the notch of the test disk 8. During the cleaning process, the exhaust fan 5 is started to extract the flying dust in the lifting cover 3, and the several air inlet pipes 9 are provided as the air inlet of the exhaust fan 5. Because they are distributed in an annular shape in the lifting cover 3, they can ensure uniform air intake in the lifting cover 3, and then ensure that the flying dust in the lifting cover 3 enters the filter tube 4 through the exhaust fan 5 for collection and filtration.

[0030] The wiring diagram of the exhaust fan 5, the servo motor 6, the electric telescopic rod 7, the vibration motor 11 and the electric push rod 12 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the exhaust fan 5, the servo motor 6, the electric telescopic rod 7, the vibration motor 11 and the electric push rod 12 are no longer explained in detail.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
