Detailed Embodiments

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. The present invention will be further described below with reference to the embodiments.

[0039] Please refer to Figures 1-4 , in an embodiment of the present application, a motor rotor cleaning device includes a machine base 1, a top base 2, and a controller 4. The top base 2 is arranged on the machine base 1, the controller 4 is arranged on the machine base 1, an installation head 17 is arranged on the top base 2, and a number of balls 18 are distributed around the inner ring of the installation head 17. A driving seat 6 is movably arranged on the machine base 1, and a slot 7 for inserting a motor rotor is formed in the driving seat 6. The cleaning device further includes:

[0040] A clamping structure arranged on the driving seat 6 for clamping and fixing the motor rotor;

[0041] A power element arranged on the machine base 1. Transmission wheels are arranged at the output end of the power element and on the driving seat 6, and the transmission wheels are connected by a belt 11; and

[0042] A cleaning system arranged on the machine base 1 and on one side of the installation head 17 and the driving seat 6 for cleaning the dust on the surface of the motor rotor; where

[0043] The cleaning system includes:

[0044] A sleeve 16, and the sleeve 16 is arranged on both the machine base 1 and the top base 2;

[0045] A driving shaft 15 movably arranged in the sleeve 16;

[0046] A driving wheel 13 arranged at one end of the driving shaft 15. A second damping strip 14 is sleeved on the driving wheel 13, and a first damping strip 12 that is slidably matched with the second damping strip 14 is equidistantly arranged on the outer wall of the belt 11;

[0047] A number of execution modules arranged equidistantly on the driving shaft 15 for absorbing the dust on the surface of the motor rotor; and

[0048] A fan 3 arranged on the top base 2 and communicated with the execution module through the driving shaft 15.

[0049] It should be noted that the power element can be a stepper motor 5 or a servo motor. In this embodiment, the resistance reducing element is preferably a stepper motor 5. The stepper motor 5 is arranged on the machine base 1, and the transmission wheel on its output end is connected to the driving seat 6 through a belt 11. As for the specific model of the stepper motor 5, the best choice can be made according to the actual situation and will not be specifically limited here.

[0050] In a specific situation of this embodiment, the clamping structure includes a plurality of clamping plates 8 and electric telescopic rods 10. The plurality of clamping plates 8 are distributed around the driving seat 6 in a circular pattern, and each clamping plate 8 is connected to the driving seat 6 through an electric telescopic rod 10.

[0051] In another specific situation of this embodiment, a rubber strip 9 is arranged on the inner side of each clamping plate 8.

[0052] During actual application, one end of the motor rotor is inserted into the mounting head 17, and the other end is inserted into the slot 7. Then, by controlling the electric telescopic rod 10 to extend, the clamping plate 8 is driven to move towards the motor rotor until the rubber strip 9 is in close contact with the motor rotor, realizing the fixed clamping of the motor rotor. Then, the controller 4 controls the stepper motor 5 to be energized and rotate. Under the action of the belt 11, the driving seat 6 is driven to rotate, thereby driving the motor rotor to rotate continuously. During the movement of the belt 11, the first damping strip 12 can meet the second damping strips 14 at different positions. Under the frictional resistance between the first damping strip 12 and the second damping strips 14, the driving wheel 13 can be driven to rotate, and then the driving shaft 15 is driven to rotate. Then, by controlling the fan 3 to work, when the fan 3 works, it can absorb the dust attached to the surface of the motor rotor along different positions of the execution module, thereby realizing the non dead angle cleaning of the motor rotor without manual cleaning by the staff.

[0053] Please refer to Figures 1-4 , as another preferred embodiment of this application, each group of the execution modules includes:

[0054] A fixed seat 19, arranged on the driving shaft 15;

[0055] A dust suction structure, arranged on the fixed seat 19 and communicated with the fan 3; and

[0056] A recycling structure, arranged between the two sleeves 16, for recycling the dust in the dust suction structure.

[0057] Exemplarily in this embodiment, the dust suction structure includes:

[0058] A connecting head 22, arranged on the fixed seat 19 and communicated with the fan 3;

[0059] The dust suction head 20 is movably arranged on the connector 22 and the two are in communication. One end of the dust suction head 20 is connected to the fixed seat 19 through an elastic member; and

[0060] The dust-proof net 23 is arranged inside the connector 22.

[0061] It should be specifically noted that the elastic member can be a spring 26, a spring piece or an elastic steel plate structure. In this embodiment, the elastic member is preferably a spring 26. The spring 26 is connected between one end of the dust suction head 20 and the fixed seat 19. As for the specific model of the spring 26, no specific limitation is made here.

[0062] While the drive shaft 15 is rotating, the fan 3 works, and can suck the dust attached to the surface of the motor rotor into the dust suction head 20. Since the dust-proof net 23 is arranged inside the connector 22, the dust sucked into the dust suction structure at this time can be temporarily stored in the dust suction head 20. When the rotation angle of the dust suction structure relative to the recovery structure reaches the set threshold value, at this time the recovery structure controls the dust suction head 20 to move relative to the connector 22, and a gap is generated between the two. At this time, the dust in the dust suction head 20 can be discharged into the recovery structure along the gap, completing the automatic recovery work of the dust.

[0063] Please refer to Figure 1 and Figure 3 , as another preferred embodiment of the present application, an inclined ramp 21 is formed inside the dust suction head 20, and the recovery structure can adjust the position of the dust suction head 20 relative to the fixed seat 19 during operation.

[0064] Exemplarily in this embodiment, the recovery structure includes a recovery box 24, a first magnet 25 and a second magnet 27;

[0065] The recovery box 24 is arranged between the two sleeves 16. The drive shaft 15 slidably penetrates through the recovery box 24. The recovery box 24 is located on one side of the fixed seat 19. The first magnet 25 and the second magnet 27 attract each other when they meet and are respectively arranged on the recovery box 24 and one end of the dust suction head 20.

[0066] It should be specifically noted that in this embodiment, it is not limited to the above first magnet 25 and second magnet 27 to adjust the position of the dust suction head 20, and a linear motor or an electric cylinder can also be used instead, which will not be listed one by one here.

[0067] When the fan 3 is working, the dust on the surface of the motor rotor is sucked into the dust suction head 20 and stored on the inclined ramp 21. While the belt 11 rotates to drive the drive shaft 15 to rotate, it can drive the fixed seat 19 and the dust suction head 20 to rotate. During this process, it can drive the separation between the first magnet 25 and the second magnet 27. At this time, under the action of the elastic restoring force of the spring 26, the dust suction head 20 and the connecting head 22 are separated. At this time, the dust in the dust suction head 20 can be discharged into the recycling box 24 through the gap between the dust suction head 20 and the connecting head 22, thus realizing the automatic recycling of dust, without the need for staff to manually clean the dust in the dust suction head 20, with a high degree of automation.

[0068] The working principle of this application:

[0069] Insert one end of the motor rotor into the mounting head 17 and the other end into the slot 7. Then, control the electric telescopic rod 10 to extend, driving the clamping plate 8 to move towards the motor rotor until the rubber strip 9 is in close contact with the motor rotor, achieving the fixed clamping of the motor rotor. Then, control the stepper motor 5 to be energized and rotate by the controller 4. Under the action of the belt 11, drive the drive seat 6 to rotate, thereby driving the motor rotor to rotate continuously. During the movement of the belt 11, the first damping strip 12 can meet the second damping strips 14 at different positions. Under the frictional resistance between the first damping strip 12 and the second damping strips 14, it can drive the driving wheel 13 to rotate, and then drive the drive shaft 15 to rotate. Then, control the fan 3 to work. When the fan 3 works, it can absorb the dust attached to the surface of the motor rotor along different positions of the execution module, thus achieving the dust-free cleaning work of the motor rotor without manual cleaning by the staff. When the fan 3 works, the dust on the surface of the motor rotor is sucked into the dust suction head 20 and stored on the inclined ramp 21. While the belt 11 rotates to drive the drive shaft 15 to rotate, it can drive the fixed seat 19 and the dust suction head 20 to rotate. During this process, it can drive the separation between the first magnet 25 and the second magnet 27. At this time, under the elastic restoring force of the spring 26, the dust suction head 20 and the connector 22 are separated. At this time, the dust in the dust suction head 20 can be discharged into the recycling box 24 through the gap between the dust suction head 20 and the connector 22, thus achieving the automatic recycling of dust without manual cleaning of the dust in the dust suction head 20 by the staff, with a high degree of automation. By equidistantly arranging a number of second damping strips 14 on the belt 11, the whole device can drive the drive shaft 15 to rotate intermittently under the frictional resistance between the first damping strip 12 and the second damping strips 14. It can not only adjust the position of the dust suction head 20 to absorb the dust at various positions of the motor rotor and achieve dust-free cleaning, but also realize the recycling of the dust in the dust suction head 20 by changing the change between the first magnet 25 and the second magnet 27, without manual cleaning of the dust in the dust suction head 20 by the staff, with a high degree of automation and avoiding the situation of blockage inside the dust suction head 20.

[0070] The above schematically describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments to this technical solution without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.

[0071] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
