[0035] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0036] like Figures 1 to 3As shown, this embodiment provides a cleaning device for cleaning a locomotive motor 100. The cleaning device includes a conveying unit 1 and a cleaning unit 2. The conveying unit 1 includes a fixed base 11 and a conveyor belt 12. The conveyor belt 12 is rotatably mounted on the fixed base 11. The conveyor belt 12 has two cleaning stations 120 spaced apart along the conveying direction. The motor 100 to be cleaned is placed on the cleaning stations 120. The cleaning unit 2 includes two cleaning structures 21 spaced apart, with the two cleaning structures 21 corresponding to the two cleaning stations 120. The cleaning structure 21 includes a six-axis robot 211, a low-pressure nozzle 212, and a high-pressure nozzle 213. The six-axis robot 211 is located in the cleaning workshop. The low-pressure nozzle 212 and the high-pressure nozzle 213 are both located at the output end of the six-axis robot 211. Driven by the six-axis robot 211, the low-pressure nozzle 212 and the high-pressure nozzle 213 can flexibly adjust the angle of the cleaning spray, ensuring comprehensive and comprehensive cleaning of the motor 100. The cleaning structure 21 has a low-pressure mode in which the low-pressure nozzle 212 sprays alone, and a high-pressure mode in which the high-pressure nozzle 213 sprays alone. In the low-pressure mode, the low-pressure nozzle 212 can spray a cleaning agent onto the motor 100; in the high-pressure mode, the high-pressure nozzle 213 can spray clean water onto the motor 100. When the motor 100 on the transmission belt passes through the first cleaning station 120, the cleaning structure 21 corresponding to the first cleaning station 120 sprays a cleaning agent onto the motor 100 to remove dirt on the surface of the motor 100; when the motor 100 is transferred to the second cleaning station 120, the cleaning structure 21 corresponding to the second cleaning station 120 sprays clean water onto the motor 100 to achieve a comprehensive flushing of the motor 100. The cleaning device adopts automated cleaning and has a high cleaning efficiency. While ensuring the cleaning effect, it can also reduce damage to the insulation layer of the motor 100 and protect the insulation performance of the motor 100.

[0037] For example, the six-axis robot 211 is an existing device disclosed in the prior art, which adopts multi-axis motion control, has high control accuracy and strong flexibility. Its specific structure and principle refer to the prior art and will not be repeated here.

[0038] Optionally, the cleaning device further includes a control unit (not shown), to which both cleaning structures 21 are connected. The control unit is capable of controlling the low-pressure mode and the high-pressure mode of the cleaning structures 21. If one cleaning structure 21 malfunctions and cannot operate normally, the operator can use the control unit to turn on both the low-pressure mode and the high-pressure mode of the other cleaning structure 21 and continue cleaning the motor 100.

[0039] Specifically, the control unit is a single-chip microcomputer disclosed in the prior art, and a relevant control program is burned on the single-chip microcomputer. In combination with the control program, the control unit can control the opening and closing of each mode of the clear structure. Exemplarily, the single-chip microcomputer is an STM32 controller, and the relevant control program refers to the prior art.

[0040] Alternatively, as Figure 3 As shown, the output end of the six-axis robot 211 is provided with a connection assembly 214. Connection assembly 214 includes a connection flange column 2141 and a fixing seat 2142. One end of the connection flange column 2141 is detachably mounted on the output end of the six-axis robot 211, and the other end is connected to the fixing seat 2142. The low-pressure nozzle 212 and the high-pressure nozzle 213 are both mounted on the fixing seat 2142. This arrangement facilitates the installation and removal of the low-pressure nozzle 212 and the high-pressure nozzle 213, which helps improve the efficiency of subsequent maintenance. Specifically, in this embodiment, the connection flange column 2141 is detachably connected to the output end of the six-axis robot 211 via bolts.

[0041] Optionally, refer to Figure 1 and Figure 2 The cleaning device also includes a water supply unit 3, which includes a detergent tank 31 and a cold water tank 32. The low-pressure nozzles 212 of the two cleaning structures 21 are both connected to the detergent tank 31, and the high-pressure nozzles 213 of the two cleaning structures 21 are both connected to the cold water tank 32. This arrangement can supply detergent to the low-pressure nozzles 212 and clean water to the high-pressure nozzles 213, ensuring a smooth cleaning process for the motor 100.

[0042] Furthermore, the water supply unit 3 includes a hot water tank 33, which is connected to the detergent tank 31. The low-pressure nozzle 212 is connected to the hot water tank 33 and the detergent tank 31. The hot water tank 33 allows the detergent to be mixed with hot water before being fed into the low-pressure nozzle 212. This not only saves detergent consumption but also improves the detergent's activity, ensuring a more effective cleaning effect on the motor 100.

[0043] Specifically, the ratio of the detergent to the hot water and the temperature of the hot water are selected as needed according to the type of detergent and are not specifically limited here.

[0044] Furthermore, the water supply unit 3 also includes a low-pressure pump unit 34 and a high-pressure pump unit 35. The hot water tank 33 and the detergent tank 31 are both connected to the input of the low-pressure pump unit 34. The two low-pressure nozzles 212 are both connected to the output of the low-pressure pump unit 34 via corresponding low-pressure pipelines 36. The cold water tank 32 is connected to the output of the high-pressure pump unit 35, and the two high-pressure nozzles 213 are both connected to the output of the high-pressure pump unit 35 via corresponding high-pressure pipelines 37. This arrangement provides power for the low-pressure nozzles 212 and high-pressure nozzles 213, ensuring a smooth cleaning process.

[0045] For example, the low-pressure pump group 34 and the high-pressure pump group 35 are both water pump devices commonly used in the art and are devices that have been disclosed in the prior art. Their specific structures and principles refer to the prior art and will not be repeated here.

[0046] Optionally, a filter assembly is provided in both the cold water tank 32 and the hot water tank 33 to filter out impurities in the water to prevent the impurities in the water from clogging the nozzle or damaging the surface of the motor 100 .

[0047] Specifically, the filter component is a filter that has been disclosed in the prior art, and its specific filtering level can be selected as needed according to actual conditions.

[0048] Optionally, a flexible pad is stacked on the cleaning station 120, and the motor 100 is placed on the flexible pad to prevent the motor 100 from being damaged by friction with the conveyor belt 12 during the conveying process, thereby ensuring the quality of the motor 100.

[0049] Exemplarily, the flexible pad is a rubber pad.

[0050] Optionally, a plurality of drainage grooves 121 are provided on the cleaning station 120 so that the water used to clean the motor 100 can be discharged in time to avoid water accumulation on the cleaning station 120 .

[0051] Optionally, the conveying unit 1 further includes water baffles (not shown), which are spaced apart on both sides of the fixed base 11 and extend in a direction parallel to the conveying direction of the conveyor belt 12. This arrangement not only blocks splashing water droplets during the cleaning process, creating a good working environment, but also effectively prevents the motor 100 from sliding off the cleaning station 120 under the impact of the high-pressure water flow, thereby ensuring the safety of the motor 100.

[0052] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
