Description

Technical Field

[0001] This invention belongs to the field of motor stator processing technology, specifically relating to a motor stator processing device and its usage method. Background Technology

[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source, or use conventional vehicle fuels with new onboard power devices, and integrate advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles. Compared with traditional fuel vehicles, new energy vehicles have advantages such as environmental protection and energy saving.

[0003] With the rapid development of new energy vehicles, the demand for motors is increasing year by year. During motor production, the motor stator needs to be impregnated with varnish to enhance its insulation performance, improve mechanical strength, increase heat dissipation efficiency, and optimize electrical performance. For example, Chinese Patent CN114825820A discloses a motor stator assembly impregnation device, which includes a rotating device, a positioning device, and an impregnation tank. This device solves the problem of uneven impregnation of stator assemblies during automatic impregnation, improving the impregnation efficiency while comprehensively achieving uniform impregnation of the stator assembly.

[0004] However, before impregnation, the motor stator needs to be cleaned and dried to remove particles or dust from its surface, thus preventing these particles or dust from affecting the subsequent impregnation process. The aforementioned patent lacks the corresponding processing steps or equipment, requiring manual cleaning of the motor stator. This not only increases the workload for workers but also reduces the efficiency of the impregnation process.

[0005] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a motor stator processing device and its usage method.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to provide a motor stator processing device and its usage method, which can solve the problems of cleaning and drying of motor stators before impregnation with paint.

[0008] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution:

[0009] A motor stator processing device includes a moving mechanism, a transfer mechanism, a linkage mechanism, a cleaning tank, and a varnish impregnation tank. The transfer mechanism includes a mounting base, multiple internal expansion columns, and an air pump. The mounting base is fixedly connected to the moving mechanism and has a flow chamber within it. The internal expansion columns are mounted on the underside of the mounting base. The air pump is mounted on the moving mechanism, with one end of each internal expansion column and the air pump's delivery end both located within the flow chamber. During air pump operation, the internal expansion columns expand and clamp the motor stator securely. The linkage mechanism is mounted within the mounting base. When the air pump delivers gas into the flow chamber, the linkage mechanism rotates, causing the multiple internal expansion columns to rotate as well. The cleaning tank is located on one side of the moving mechanism and contains cleaning fluid. The varnish impregnation tank is located on one side of the moving mechanism and contains varnish.

[0010] In one or more embodiments of the present invention, the moving mechanism includes a guide rail, a movable seat, a lifting cylinder, and a mounting frame.

The mounting frame is mounted on the free end of the lifting cylinder, and the mounting chassis and the air pump are both connected to the mounting frame.

[0011] In one or more embodiments of the present invention, the internal expansion column includes a connecting portion, an expansion portion, and an air bladder. The connecting portion is rotatably connected to the mounting chassis, and one end of the connecting portion is disposed within the flow cavity. The expansion portion is disposed on the lower side of the mounting chassis and is integrally formed with the connecting portion. The expansion portion has an air passage inside, and a plurality of air holes are provided on the sidewall of the expansion portion. The air passage communicates with the outside through the air holes. The air bladder is disposed on the outside of the expansion portion and covers the air holes.

[0012] In one or more embodiments of the present invention, the expansion portion is provided with a plurality of ejection cavities, the ejection cavities are connected to the air passage, a support column is slidably provided in the ejection cavity, one end of the support column may protrude from the side wall of the expansion portion, and a spring is provided in the ejection cavity, the spring surrounding the support column.

[0013] In one or more embodiments of the present invention, the mounting chassis further includes a meshing cavity, and the linkage mechanism includes a rotating shaft, multiple force-receiving blades, a driving gear, and multiple driven gears. The rotating shaft is rotatably connected to the mounting chassis, with its two ends respectively located in the flow cavity and the meshing cavity. The force-receiving blades are connected to the sidewall of the rotating shaft and located in the flow cavity. The driving gear is connected to the sidewall of the rotating shaft and located in the meshing cavity. The driven gears are respectively connected to the sidewalls of the multiple connecting portions and located in the meshing cavity, and the driven gears mesh with the driving gears.

[0014] In one or more embodiments of the present invention, the cleaning tank is provided with a hollow disc, and a plurality of top pipes are connected to the upper end face of the hollow disc. The plurality of top pipes correspond to a plurality of expansion parts respectively, and the upper end face of the cleaning tank is provided with a plurality of air outlets.

[0015] In one or more embodiments of the present invention, the lower bottom of the expansion portion is provided with a cavity and an insertion cavity that communicate with each other, and the cavity is connected to the air passage.

[0016] In one or more embodiments of the present invention, a sealing mechanism is installed within the expansion portion. The sealing mechanism includes a sealing plate, a movable rod, a cover plate, a limiting plate, and an elastic sleeve. The sealing plate is disposed within the cavity and covers the insertion cavity, and has multiple through holes. The movable rod is slidably disposed on the sealing plate. The cover plate is connected to one end of the movable rod and is disposed within the cavity, covering the through holes. The limiting plate is connected to the other end of the movable rod and is disposed within the insertion cavity, allowing the top tube to be inserted into the insertion cavity and contact the limiting plate. The elastic sleeve is disposed between the sealing plate and the limiting plate and surrounds the movable rod.

[0017] In one or more embodiments of the present invention, a plurality of arc-shaped components are connected to the bottom wall of the mounting chassis, and the plurality of arc-shaped components correspond to a plurality of internal expansion columns respectively. A plurality of first nozzles are connected to the bottom surface of the arc-shaped components. A connecting pipe is connected between the arc-shaped components and the flow cavity. A first control valve is installed on the connecting pipe. An expansion pipe is connected to the air pump's air delivery end. The expansion pipe is located inside the flow cavity. A heater is installed inside the expansion pipe.

[0018] A method of using an electric motor stator processing device includes the following steps:

[0019] S1. The air pump is operated, and the air pump delivers gas to the flow chamber. The gas in the flow chamber enters the air passage in the expansion section through multiple connecting parts, and then enters the inside of the air bag through the air hole, causing the air bag to expand. The expanded air bag can squeeze the inside of the motor stator. At the same time, some of the gas in the air passage enters the ejection chamber. When the gas compressive force on the support column is greater than the spring force, the support column will protrude from the side wall of the expansion section to support the bottom of the motor stator. The motor stator is fixed by multiple protruding support columns and the expanded air bag.

[0020] S2. The motor stator is raised by the lifting cylinder, and the motor stator is moved to the upper side of the cleaning tank by the sliding of the moving seat on the guide rail. Then the lifting cylinder is retracted to lower the motor stator and place it in the cleaning liquid in the cleaning tank.

[0021] S3. Continue to control the motor stator to descend until the top tube contacts the limiting plate through the insertion cavity. The limiting plate is squeezed by the top tube and the cover plate is removed from the through hole by the movable rod. At this time, the air passage, cavity, insertion cavity, top tube and hollow plate are connected.

[0022] S4. Run the air pump again. The air pump continues to deliver gas to the flow chamber. The gas flows through the air passage, cavity, insertion chamber, top tube and hollow plate. Finally, it is discharged into the cleaning tank through the air outlet. The discharged gas will blow the cleaning liquid towards the motor stator for aeration cleaning of the motor stator.

[0023] S5. When the gas flows in the flow chamber, the gas will blow towards the force-bearing blades and drive the rotating shaft and the drive gear to rotate. Since the drive gear meshes with the driven gear, the driven gear and the internal expansion column will also rotate, thereby causing the motor stator to rotate in the cleaning fluid to improve the cleaning effect of the cleaning fluid on the motor stator.

[0024] S6. After the motor stator is cleaned, the lifting cylinder is extended to raise the motor stator and remove it from the cleaning fluid. At this time, the cover plate covers the through hole again under the action of the limit plate, elastic sleeve and gas in the cavity. The gas no longer exits through the insertion cavity. The first control valve on the connecting pipe is opened, and the gas in the flow cavity enters the arc-shaped part through the connecting pipe. Then it is blown onto the motor stator through multiple first nozzles. With the rotation of the motor stator, the motor stator can be dried.

[0025] S7. When drying the motor stator, the heater is operated. The heater can heat the gas entering the flow chamber in time to increase the gas temperature, which in turn can increase the drying gas temperature and further improve the drying efficiency of the motor stator.

[0026] S8. After the motor stator has finished drying, stop the air pump and move the motor stator to the top of the paint soaking tank. Then control the lifting cylinder to retract so that the motor stator is placed in the paint soaking tank to complete the paint soaking operation.

[0027] Compared with the prior art, the motor stator processing device and its method of use of the present invention can clean and dry the motor stator before impregnation with paint to remove particulate matter or dust from the surface of the motor stator, so as to avoid the particulate matter or dust affecting the subsequent impregnation with paint, while also reducing the burden on workers and improving the overall efficiency of motor stator impregnation with paint.

Detailed Implementation

[0047] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0048] like Figures 1 to 15As shown, an embodiment of the present invention provides a motor stator processing device, comprising a moving mechanism 1, a transfer mechanism 2, a linkage mechanism 3, a cleaning tank 4, and a varnish impregnation tank 5. The transfer mechanism 2 includes a mounting base 201, multiple internal expansion columns 202, and an air pump 203. The mounting base 201 is fixedly connected to the moving mechanism 1, and a flow chamber 2011 is provided within the mounting base 201. The internal expansion columns 202 are mounted on the lower side of the mounting base 201. The air pump 203 is mounted on the moving mechanism 1, with one end of each internal expansion column 202 and the air delivery end of the air pump 203 both located within the flow chamber 2011. When the air pump 203 operates, it expands the internal expansion columns 202 and clamps and fixes the motor stator. The linkage mechanism 3 is installed within the mounting base 201. When the air pump 203 delivers gas into the flow chamber 2011, it rotates the linkage mechanism 3, which in turn rotates the multiple internal expansion columns 202. The cleaning tank 4 is located on one side of the moving mechanism 1 and contains cleaning fluid. The immersion tank 5 is located on one side of the moving mechanism 1, and the immersion tank 5 contains immersion paint.

[0049] The air pump 203 is operated to supply gas to the flow chamber 2011. The gas in the flow chamber 2011 can enter multiple internal expansion columns 202. The internal expansion columns 202 expand internally under the action of the gas, thereby fixing the motor stator and facilitating subsequent transfer, cleaning, and varnishing of the motor stator. This application, by setting multiple internal expansion columns 202, can simultaneously fix multiple motor stators, thereby improving the cleaning and varnishing efficiency of the motor stator. The linkage mechanism 3 can drive the internal expansion columns 202 to rotate under the action of the gas, thereby improving the subsequent cleaning effect of the motor stator. The motor stator can be cleaned by placing it in the cleaning solution in the cleaning tank 4, and the electronic stator can be varnished by placing it in the varnish in the varnish dipping tank 5.

[0050] like Figure 1 As shown, the moving mechanism 1 includes a guide rail 101, a moving base 102, a lifting cylinder 103, and a mounting frame 104. The guide rail 101 is mounted on the ground. The moving base 102 is slidably mounted on the guide rail 101. The lifting cylinder 103 is fixedly connected to the moving base 102. The mounting frame 104 is mounted on the free end of the lifting cylinder 103, and both the mounting chassis 201 and the air pump 203 are connected to the mounting frame 104.

[0051] The positions of the lifting cylinder 103, mounting bracket 104, and motor stator can be adjusted by moving the movable base 102 on the guide rail 101, so that the motor stator can be cleaned or dipped in paint. The vertical height of the motor stator can be adjusted by extending and retracting the lifting cylinder 103. The mounting bracket 104 is used to install the transfer mechanism 2.

[0052] like Figures 2 to 15As shown, the inner expansion column 202 includes a connecting part 2021, an expansion part 2022, and an airbag 2023. The connecting part 2021 is rotatably connected to the mounting base 201, and one end of the connecting part 2021 is located inside the flow cavity 2011, allowing gas to flow through it. The expansion part 2022 is located on the lower side of the mounting base 201 and is integrally formed with the connecting part 2021, ensuring the integrity of the two parts. The expansion part 2022 has an air passage, and its sidewall has multiple air holes 2024, through which the air passage connects to the outside. The airbag 2023 is located outside the expansion part 2022 and covers the air holes 2024. Gas from the air passage can enter the airbag 2023 through the air holes 2024, causing the airbag 2023 to inflate.

[0053] In this embodiment, the airbag 2023 is made of butyl rubber, which can withstand temperatures not exceeding 150°C, ensuring the service life of the airbag 2023.

[0054] like Figure 16 As shown, the motor stator in this application includes a stator body 01, and the stator body 01 has a central hole 02 and a plurality of tooth grooves 03 in the middle, with the central hole 02 and the tooth grooves 03 connected.

[0055] The expansion section 2022 is inserted into the central hole 02. The air pump 203 is operated, and the air pump 203 delivers gas to the flow chamber 2011. The gas in the flow chamber 2011 enters multiple connecting sections 2021 and then enters the air passages in the expansion section 2022. The gas in the air passages enters the air bag 2023 through the air hole 2024, causing the air bag 2023 to inflate. The inflated air bag 2023 can contact the side wall of the central hole 02, and part of the air bag 2023 can penetrate into the tooth groove 03, thereby fixing the stator body 01 without affecting the cleaning and impregnation of the stator body 01 and the side wall of the tooth groove 03.

[0056] like Figures 2 to 15 As shown, the expansion section 2022 is provided with multiple ejection chambers 2025, which are connected to the air passage, allowing gas in the air passage to enter the ejection chambers 2025. A support column 2026 is slidably provided in the ejection chamber 2025, with one end of the support column 2026 protruding from the side wall of the expansion section 2022. A spring 2027 is provided in the ejection chamber 2025, and the spring 2027 surrounds the support column 2026.

[0057] When the gas pressure in the ejection chamber 2025 is greater than the force exerted by the spring 2027 on the support column 2026, the support column 2026 is squeezed out of the side wall of the expansion part 2022. At this time, the bottom of the stator body 01 can be supported by the protruding support column 2026. That is, the stator body 01 can be fixed by the cooperation of the support column 2026 protruding from the side wall of the expansion part 2022 and the expansion airbag 2023, so as to facilitate the subsequent transfer, cleaning and impregnation of the stator body 01.

[0058] When the gas pressure in the ejection chamber 2025 is less than the force exerted by the spring 2027 on the support column 2026, the support column 2026 retracts under the action of the spring 2027. At this time, the support column 2026 will not protrude from the side wall of the expansion part 2022, making it easier to remove the motor stator from the inner expansion column 202.

[0059] In this embodiment, the support column 2026 and the side wall of the mounting chassis 201 are provided with sealing rings to prevent cleaning fluid or paint from affecting the spring 2027.

[0060] like Figures 1 to 15 As shown, the mounting chassis 201 also includes a meshing cavity 2012. The linkage mechanism 3 includes a rotating shaft 301, multiple force-receiving blades 302, a driving gear 303, and multiple driven gears 304. The rotating shaft 301 is rotatably connected to the mounting chassis 201, with its two ends respectively located in the flow cavity 2011 and the meshing cavity 2012. The force-receiving blades 302 are connected to the side wall of the rotating shaft 301 and are located in the flow cavity 2011. Under the action of gas, the force-receiving blades 302 can drive the rotating shaft 301 and the driven gears 304 to rotate. At the same time, the force-receiving blades 302 can diffuse the gas in the flow cavity 2011 to improve the efficiency of gas entering the multiple connecting parts 2021. The driving gears 303 are connected to the side wall of the rotating shaft 301 and are located in the meshing cavity 2012. Driven gears 304 are connected to the side walls of multiple connecting parts 2021 and are located in the meshing cavity 2012. Driven gears 304 mesh with driving gears 303.

[0061] The rotating shaft 301 is used to mount the force-bearing blade 302 and the driving gear 303. When gas flows in the flow chamber 2011, the gas blows towards the force-bearing blade 302, causing the rotating shaft 301 and the driving gear 303 to rotate. Since the driving gear 303 meshes with the driven gear 304, the driving gear 303 can drive the driven gear 304 to rotate, thereby causing the inner expansion column 202 to rotate. When the inner expansion column 202 fixes the motor stator, the motor stator will also rotate.

[0062] Preferably, in this application, the gear ratio between the driving gear 303 and the driven gear 304 is 1:3. On the one hand, this avoids insufficient blowing force from the air pump 203, ensuring that the driving gear 303 can drive the driven gear 304 to rotate. On the other hand, when the airbag 2023 expands and fixes the stator body 01, it prevents the driving gear 303 from driving the driven gear 304 and the inner expansion column 202 to rotate too quickly, which could cause the airbag 2023 to pull against the central hole 02, thereby preventing damage to the airbag 2023.

[0063] like Figures 13 to 15 As shown, the cleaning tank 4 is equipped with a hollow disc 401. Multiple top pipes 402 are connected to the upper surface of the hollow disc 401, and each top pipe 402 corresponds to a multiple expansion section 2022. Multiple air outlets 403 are provided on the upper surface of the cleaning tank 4. Gas in the air passage can enter the hollow disc 401 through the top pipes 402 and then exit through the multiple air outlets 403, used to blow the cleaning liquid in the cleaning tank 4 towards the motor stator, thereby improving the cleaning effect on the motor stator.

[0064] like Figures 1 to 15 As shown, the lower bottom of the expansion section 2022 is provided with an interconnected cavity 2028 and an insertion cavity 2029, with the cavity 2028 connected to the air passage. Some of the gas in the air passage can flow through the cavity 2028 and the insertion cavity 2029.

[0065] The expansion section 2022 houses a sealing mechanism 204, which seals the insertion cavity 2029. The sealing mechanism 204 includes a sealing plate 2041, a movable rod 2043, a cover plate 2044, a limiting plate 2045, and an elastic sleeve 2046. The sealing plate 2041 is located within the cavity 2028 and covers the insertion cavity 2029. The sealing plate 2041 has multiple through holes 2042. When the through holes 2042 are not blocked, gas in the airway can flow through the cavity 2028, the through holes 2042, and the insertion cavity 2029.

[0066] Additionally, the movable rod 2043 is slidably mounted on the sealing plate 2041. A cover plate 2044 is connected to one end of the movable rod 2043 and is located within the cavity 2028, covering the through hole 2042. When the cover plate 2044 covers the through hole 2042, gas in the airway cannot flow through the insertion cavity 2029. A limiting plate 2045 is connected to the other end of the movable rod 2043 and is located within the insertion cavity 2029, allowing the top tube 402 to be inserted into the insertion cavity 2029 and contact the limiting plate 2045. An elastic sleeve 2046 is located between the sealing plate 2041 and the limiting plate 2045, and surrounds the movable rod 2043.

[0067] When the motor stator is placed in the cleaning tank 4, the jacking pipe 402 can pass through the insertion cavity 2029 to contact and squeeze the limiting plate 2045, thereby causing the cover plate 2044 to detach from the through hole 2042. The operating air pump 203 can continuously deliver gas into the flow cavity 2011, thereby causing continuous gas flow in the flow cavity 2011, expansion section 2022, air passage, cavity 2028, through hole 2042, insertion cavity 2029, jacking pipe 402, hollow disk 401 and air outlet 403. The continuously flowing gas can not only blow the cleaning fluid to the motor stator, but also cause the force-bearing blade 302 to drive the rotating shaft 301, driving gear 303, driven gear 304 and inner expansion column 202 to rotate continuously. Combined with the cleaning fluid, the cleaning effect of the motor stator can be improved.

[0068] like Figures 11 to 12 As shown, multiple arc-shaped components 205 are connected to the bottom wall of the mounting chassis 201. Each arc-shaped component 205 corresponds to a multiple internal expansion pillar 202, as shown below. Figure 12 As shown, multiple first nozzles 2051 are connected to the bottom surface of the arc-shaped component 205. A connecting pipe 2052 connects the arc-shaped component 205 and the flow chamber 2011, and a first control valve is installed on the connecting pipe 2052. When the motor stator is removed from the cleaning fluid, the first control valve is opened, and the gas in the flow chamber 2011 enters the arc-shaped component 205 through the connecting pipe 2052, and then is blown onto the cleaned motor stator through the multiple first nozzles 2051. Since the gas is continuously flowing in the flow chamber 2011, the gas will also blow onto the force-bearing blade 302, and drive the rotating shaft 301, the driving gear 303, the driven gear 304, and the inner expansion column 202 to rotate, thereby causing the motor stator to rotate, so as to better dry the motor stator and remove moisture from the surface of the motor stator.

[0069] like Figures 7 to 8 As shown, the air pump 203 has an expansion pipe 2031 connected to its air delivery end. The expansion pipe 2031 is located inside the flow chamber 2011, and a heater 2032 is installed inside the expansion pipe 2031. The expansion pipe 2031 is used to diffuse the gas entering the flow chamber 2011, allowing the gas to be better directed towards the force-bearing blades 302, thereby driving the rotating shaft 301 and the drive gear 303 to rotate. The heater 2032 is used to instantly heat the gas flowing inside the expansion pipe 2031, thereby increasing the temperature of the gas entering the flow chamber 2011, which in turn increases the temperature of the gas subsequently used to dry the motor stator, thus improving the drying efficiency of the motor stator.

[0070] The flow chamber 2011 is further equipped with an annular pipe 206. Multiple evenly distributed second nozzles 2061 are connected to the outer wall of the annular pipe 206. The second nozzles 2061 pass through the mounting base 201. An air inlet pipe 2062 is connected to the annular pipe 2062, and a second control valve is installed on the air inlet pipe 2062. When the second control valve is opened, the gas in the flow chamber 2011 enters the annular pipe 206 through the air inlet pipe 2062, and then exits to the outside of the mounting base 201 through the multiple second nozzles 2061, forming an annular air curtain on the outside of the mounting base 201.

[0071] When the motor stator is placed in the immersion tank 5, the air pump 203 and the second control valve can be turned on, so that gas continues to flow in the flow chamber 2011. This allows the linkage mechanism 3 to drive the internal expansion column 202 and the motor stator to rotate, thereby improving the immersion effect of the motor stator. At the same time, when the gas in the flow chamber 2011 is discharged through multiple second nozzles 2061, an annular air curtain can be formed on the outside of the mounting chassis 201 to isolate the paint odor during the immersion of the motor stator.

[0072] When the motor stator is being cleaned in the cleaning tank 4 or dipped in the paint immersion tank 5, the mounting base 201 can act as a cover to block the upper openings of the cleaning tank 4 and the paint immersion tank 5, thereby preventing splashing of cleaning fluid or paint.

[0073] Of course, a hollow plate 401 can also be installed at the bottom of the immersion tank 5 to cooperate with the inner expansion column 202 to better immerse the motor stator.

[0074] A method of using an electric motor stator processing device includes the following steps:

[0075] S1. Insert the expansion section 2022 into the center hole 02, run the air pump 203, and the air pump 203 delivers gas to the flow chamber 2011. The gas in the flow chamber 2011 enters the air passage in the expansion section 2022 through multiple connecting parts 2021, and then enters the inside of the air bag 2023 through the air hole 2024, causing the air bag 2023 to expand. The expanded air bag 2023 can contact the side wall of the center hole 02, and part of the air bag 2023 will enter the tooth groove 03. At the same time, part of the gas in the air passage enters the ejection chamber 2025. When the gas compressive force on the support column 2026 is greater than the elastic force of the spring 2027, the support column 2026 will protrude from the side wall of the expansion section 2022 to support the bottom of the motor stator. That is, the motor stator is fixed by multiple protruding support columns 2026 and the expanded air bag 2023.

[0076] S2. Control the extension of the lifting cylinder 103 to raise the motor stator, and move the motor stator to the upper side of the cleaning tank 4 by sliding the moving seat 102 on the guide rail 101. Then control the retraction of the lifting cylinder 103 to lower the motor stator and place it in the cleaning liquid in the cleaning tank 4.

[0077] S3. Continue to control the motor stator to descend until the jacking tube 402 contacts the limiting plate 2045 through the insertion cavity 2029. The limiting plate 2045 is squeezed by the jacking tube 402 and the cover plate 2044 is removed from the cover of the through hole 2042 through the movable rod 2043. At this time, the air passage, cavity 2028, insertion cavity 2029, jacking tube 402 and hollow plate 401 are connected.

[0078] S4. Run the air pump 203. The air pump 203 continues to deliver gas to the flow chamber 2011. The gas flows through the air passage, cavity 2028, insertion chamber 2029, top pipe 402 and hollow plate 401. Finally, it is discharged into the cleaning tank 4 through the air outlet 403. The discharged gas will blow the cleaning liquid towards the motor stator for aeration and cleaning of the motor stator.

[0079] S5. When the gas flows continuously in the flow chamber 2011, the gas will blow towards the force-bearing blade 302 and drive the rotating shaft 301 and the drive gear 303 to rotate. Since the drive gear 303 meshes with the driven gear 304, the driven gear 304 and the inner expansion column 202 will also rotate, thereby causing the motor stator to rotate in the cleaning fluid to improve the cleaning effect of the cleaning fluid on the motor stator.

[0080] S6. After the motor stator is cleaned, the lifting cylinder 103 is extended to raise the motor stator and remove it from the cleaning fluid. At this time, the cover plate 2044 covers the through hole 2042 again under the action of the limiting plate 2045, the elastic sleeve 2046 and the gas in the cavity 2028. The gas no longer exits through the insertion cavity 2029. The first control valve on the connecting pipe 2052 is opened, and the gas in the flow cavity 2011 enters the arc-shaped part 205 through the connecting pipe 2052, and then blows onto the motor stator through multiple first nozzles 2051. Since there is continuous gas flow in the flow cavity 2011, the motor stator is always in a rotating state, so that the motor stator can be dried.

[0081] S7. When drying the motor stator, the heater 2032 is operated. The heater 2032 can heat the gas entering the flow chamber 2011 in time to increase the gas temperature, thereby increasing the drying gas temperature and further improving the drying efficiency of the motor stator.

[0082] S8. After the motor stator is dried, stop the air pump 203 and move the motor stator to the upper side of the immersion tank 5. Then control the lifting cylinder 103 to retract so that the motor stator is placed in the immersion tank to complete the immersion operation.

[0083] S9. During the impregnation of the motor stator, the air pump 203 can also be operated and the second control valve can be opened at the same time. The gas in the flow chamber 2011 enters the annular pipe 206 through the air inlet pipe 2062 and then is discharged to the outside of the mounting chassis 201 through the second nozzle 2061. This not only enables the linkage mechanism 3 to drive the inner expansion column 202 and the motor stator to rotate, thereby improving the impregnation effect of the motor stator, but also forms an annular air curtain on the outside of the mounting chassis 201 to isolate the paint smell during the impregnation of the motor stator.

The air pump is operated, and the air pump delivers gas to the flow chamber. The gas in the flow chamber enters the air passage in the expansion section through multiple connecting parts, and then enters the inside of the air bag through the air hole, causing the air bag to expand. The expanded air bag can squeeze the inside of the motor stator. At the same time, some of the gas in the air passage enters the ejection chamber.
