Description

Technical Field

[0001] This invention relates to the field of stator impregnation technology, and more particularly to an equipment and process for impregnating motor stators. Background Technology

[0002] In the field of motor manufacturing, the stator, as the core component of the motor, directly determines the motor's operational stability, service life, and safety performance through its insulation performance. The impregnation process is a crucial step in improving the stator's insulation performance. By immersing the stator windings in insulating varnish, the varnish fully penetrates the wire gaps, slot gaps, and end coil gaps, forming a complete and uniform insulating coating. This effectively isolates electrical interference between wires, prevents moisture and dust intrusion, and enhances the windings' mechanical strength and heat dissipation capacity. Therefore, the appropriateness of the impregnation equipment and process is of paramount importance to the overall quality of the motor. However, the existing dipping process has its drawbacks. Although the method of immersing the entire workpiece in the paint tank is highly efficient and the stator winding is fully dipped in paint, it requires manual operation next to the paint tank when the line is not automated. The paint odor is strong and affects the health of the employees. At the same time, the workpiece has serious paint nodules after dipping, and there is paint residue in the assembly positions such as the central hole, which has an adverse effect on subsequent assembly. While the workpiece-rotating paint-drip process results in better paint nodules and less residual paint at installation locations such as central holes, facilitating subsequent assembly, it also presents challenges such as difficult machine adjustment, insufficient paint penetration into the coil, lower efficiency, and higher requirements for the paint pump. In summary, existing impregnation processes struggle to achieve a good balance between sufficient impregnation, employee health, ease of subsequent assembly, and production efficiency. Therefore, a motor stator impregnation equipment and process need to be designed.

[0003] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0004] This invention provides a motor stator impregnation equipment and process to solve the problems of existing impregnation processes, such as the impact of immersion on employee health and assembly, the difficulty of adjusting the machine, the high risk of paint seepage and low efficiency, and the high requirements for paint pumps. All of these make it difficult to balance multiple needs.

[0005] The present invention adopts the following technical solution: a motor stator impregnation equipment and process. It includes a support frame, on which an mounting frame is fixed; a conveying assembly disposed on the mounting frame, the conveying assembly including a conveying section fixed on the mounting frame and used to restrict the movement trajectory of the stator to be impregnated, the conveying section having multiple sets of mounting sections for fixing the stator to be impregnated; a driving assembly disposed on the conveying section, the driving assembly providing power to the mounting sections; and an impregnation assembly disposed below the mounting frame, the impregnation assembly including an impregnation section disposed below the mounting frame for supplying and storing paint to meet the needs of stator impregnation, the impregnation section having two sets of friction sections installed, the friction sections being adapted to move with the drive assembly driving the mounting sections to rotate the stator to be impregnated mounted on the mounting sections.

[0006] Furthermore, the conveying unit includes a conveying guide rail fixed on the mounting frame structure. The conveying guide rail consists of three parts: two sets of horizontally arranged horizontal ends, a recessed section connected between the two sets of horizontal ends, and the two sets of horizontal ends and the recessed section connected to form a concave conveying structure.

[0007] Furthermore, the mounting part includes a rotating shaft disposed below the conveying guide rail. Both ends of the rotating shaft are connected to mounting shafts via bearings. The mounting shaft is adapted to fit multiple sets of stator workpieces. One end of the mounting shaft is threadedly connected to a limiting part. A tripod is fixed on the rotating shaft. The vertical section of the tripod is connected to the mounting shaft, and the horizontal section is movably connected to a contact wheel near the two corners. The contact wheel rolls within the T-shaped groove of the conveying guide rail.

[0008] Furthermore, the drive assembly includes a set of mounting base plates fixed to the two sides of the horizontal end of the conveying guide rail. Multiple sets of bearing seats are symmetrically fixed on the two sets of mounting base plates. A second contact wheel is movably arranged between the two sets of oppositely arranged bearing seats. The second contact wheel has a roller shaft, and the two ends of the roller shaft are movably arranged through the bearing seats at both ends.

[0009] Furthermore, the two sets of symmetrical bearing seats and the set of contact wheels are defined as a rotating unit. One end of the roller shaft of the multiple rotating units is fixed with a sprocket. The sprockets of adjacent rotating units are connected by a transmission chain. The side of the mounting base is fixed with a drive motor. The drive motor is connected to one end of the roller shaft of a set of rotating units through a coupling. The rotating unit in the middle has multiple sets of sprockets fixed on its roller shaft.

[0010] Furthermore, the impregnation section includes an impregnation master tank disposed below the mounting frame. The impregnation master tank is used to store paint liquid. Two sets of support brackets are installed on the impregnation master tank. The support brackets are composed of horizontal rods and vertical rods. Impregnation sub-tanks are fixed to the side of the vertical rods of the support brackets.

[0011] Furthermore, the impregnation sub-tank consists of storage area one, storage area two, and an asphalt recovery plate with a slope connecting one end of storage area one and storage area two. A transfer pump is connected to the side of the impregnation mother tank, and one end of the transfer pump is connected to storage area one and storage area two through a transfer pipe. Liquid level gauges are installed in both storage area one and storage area two.

[0012] Furthermore, the friction part has an elongated structure and is arranged along the length of the conveying guide rail. The middle section of the friction part has a downward tendency and is adapted to the shape of the conveying guide rail. The stator workpiece is partially immersed in paint. There is a gap between the storage area one and the storage area two. A connecting plate is fixed within the gap. The rotating shaft is adapted to rotate on the connecting plate. A friction wheel is fixedly sleeved on the mounting shaft between the stator workpiece and one end of the rotating shaft.

[0013] Furthermore, a processing component is provided inside the support frame. The processing component includes a movable part fixed to the inner wall of the support frame. The movable part includes a mounting panel horizontally disposed on the inner wall of the support frame. Parallel slide rails one and two are fixed on the mounting panel. Limiting blocks are provided at both ends of slide rails one and two. A friction wheel two is mounted on the mounting panel between slide rails one and two. A contact rod one is slidably disposed on slide rail one, and a contact rod two is slidably disposed on slide rail two. Both contact rod one and contact rod two are in close contact with the friction wheel two.

[0014] The mounting panel is provided with a reset part, which includes a mounting corner block fixedly mounted on the mounting panel near one end. A reset spring is fixed to the side of the mounting corner block. One end of the reset spring is connected to one end of the second contact rod. Every three sets of mounting parts have a mounting shaft with a threaded connection to one end of it. The third contact wheel is adapted to contact the first contact rod and synchronously push the first contact rod to the right. The second contact rod is provided with a scraping part, which includes a right-angle rod fixed to the side of the second contact rod. One end of the right-angle rod is fixed with a concave frame. A scraper is movably arranged between the inner walls of the concave frame. At the same time, a stop bar is fixed on the right side of the inner wall of the concave frame, which is located on the right side of the scraper.

[0015] Furthermore, step one includes: the stator workpiece is fixed on the mounting shaft, the PLC starts the drive motor, and through transmission, the second contact wheel pushes the first contact wheel, which drives the mounting part to move along the guide rail; Step 2: The workpiece is partially immersed in paint in the sinking section. The friction wheel drive makes the workpiece rotate evenly for paint immersion. The PLC controls the delivery pump to stabilize the paint liquid according to the level gauge. Step 3: After the workpiece is dipped in paint and the mounting part is moved to the right end, the contact wheel pushes the contact rod, causing the scraping part to move to the left; Step 4: The scraper vertically scrapes back the paint liquid. After the contact rod touches the limit block, the reset spring resets the scraping part, completing the recycling and circulation.

[0016] The technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects: 1. A motor stator impregnation equipment and process, wherein the conveying component restricts the stator's movement trajectory through the conveying section and fixes the stator through the mounting section, and works with the drive component to provide power for stator conveying, realizing automated stator conveying and impregnation, eliminating the need for manual operation at close range next to the paint tank, and reducing the health hazards of paint odor to employees; the impregnation section of the impregnation component meets the needs of paint supply, storage and impregnation, and the friction part on it moves with the drive component to drive the mounting section, causing the stator to rotate and impregnate, which avoids the serious paint nodules and paint residue at the assembly position caused by complete immersion, improves the convenience of subsequent assembly, and avoids the risk of insufficient paint penetration in the rotating dripping paint process, ensuring sufficient impregnation of the coil; at the same time, the automated design improves production efficiency, eliminates the need for high-requirement paint pumps, reduces the difficulty and cost of machine adjustment, and ultimately achieves a good balance between sufficient impregnation, employee health, assembly convenience and production efficiency; 2. The concave structure of the conveyor rail can guide the stator to be transported smoothly in the horizontal section and accurately immersed in the paint when it reaches the sinking section. This ensures that the paint immersion process is orderly and avoids excessive displacement of the stator, which would affect the paint immersion effect. 3. Through the structural design of the mounting section, multiple sets of stators are stably fixed by the mounting shaft and the limiting part, while the moving resistance of the mounting section is reduced by the use of the tripod and the contact wheel, so as to ensure that the stator is transported smoothly and is easy to load and unload. 4. By cooperating with the bearing housing of the drive assembly and the second contact wheel, a stable contact support is provided for the first contact wheel, ensuring efficient power transmission and enabling the mounting part to move smoothly along the conveying guide rail, thus ensuring the reliability of stator conveying. 5. By combining the rotating unit, sprockets, chains and drive motor, multiple sets of contact wheels can rotate synchronously, ensuring continuous and stable power transmission. The multiple sprockets in the middle rotating unit can adapt to different installation requirements and improve the equipment's adaptability. 6. The impregnation master tank provides ample paint storage, and the combination of the support bracket and the impregnation sub-tank allows for flexible adjustment of the sub-tank height, adapting to the impregnation needs of stators of different sizes and improving the equipment's versatility.

[0017] 7. By combining the partitioned design of the impregnation tank with the paint recovery plate, the paint liquid can be stored in partitions and excess paint liquid can be recovered. The transfer pump and level gauge ensure a stable supply of paint liquid, reduce paint liquid waste and ensure the quality of impregnation. 8. The stator is partially impregnated to avoid over-impregnation. The connecting plate and friction wheel work together to ensure that the stator can rotate stably during impregnation, which ensures sufficient impregnation and reduces paint nodules and paint residue at the assembly position. 9. By coordinating the moving and resetting parts of the processing components, the scraping part can be automatically moved and reset. The scraper scrapes the paint in a directional manner under the action of the baffle, efficiently recovering the residual paint on the paint recovery plate, further reducing paint waste, and ensuring that the recovery process does not cause reverse pollution.

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example 1:

[0022] Reference Figures 1 to 2 As shown, this embodiment of the invention provides a motor stator impregnation equipment and process, including a support component 1. The support component 1 includes a support frame 11 located at the bottom. The support frame 11 serves as the foundation for stabilizing the entire equipment and can withstand the load during equipment operation. An installation frame 12 is fixed on the top of the support frame 11, and the installation frame 12 provides a stable platform for the subsequent installation of various components.

[0023] A conveying assembly 2 is provided within the frame structure of the mounting frame 12. The conveying assembly 2 includes a conveying section fixed within the frame structure of the mounting frame 12. The conveying section includes a conveying guide rail 21 fixed on the frame structure of the mounting frame 12. The conveying guide rail 21 consists of three parts: two sets of horizontally arranged horizontal ends, and a recessed section 22 connected between the two sets of horizontal ends. The two sets of horizontal ends and the recessed section 22 are connected to form a concave conveying structure. In actual use, when the fixed workpiece to be dipped in paint is transported to the recessed section 22, a local part of the workpiece to be dipped in paint is immersed in the paint liquid to realize the dipping operation.

[0024] like Figures 4-5As shown, a T-shaped groove 23 is provided inside the conveying guide rail 21. Multiple mounting parts for fixing the workpieces to be impregnated are provided in the groove 23. Each mounting part includes a rotating shaft 24 located below the conveying guide rail 21. The two ends of the rotating shaft 24 are connected to mounting shafts 25 through bearings. Multiple sets of stator workpieces 27 are suitable for being sleeved on the mounting shafts 25 to facilitate the installation and removal of the stator workpieces 27. At the same time, a limiting part 26 is threadedly connected to one end of the mounting shaft 25. The limiting part 26 can effectively prevent the stator workpieces 27 sleeved on the mounting shaft 25 from slipping off, ensuring the stability of the workpieces during the impregnation process.

[0025] In addition, a tripod 28 is fixed on the rotating shaft 24. It should be noted that the vertical section of the tripod 28 is connected to the mounting shaft 25, and the horizontal section is movably connected to the two corners of the two corners. The contact wheel 29 rolls in the T-shaped groove 23 of the conveying guide rail 21. The rolling friction replaces the sliding friction, which reduces the resistance during movement. This helps the mounting part to move smoothly and steadily in the groove 23 of the conveying guide rail 21, ensuring that the stator workpiece 27 remains stable during the conveying process and providing a guarantee for the smooth progress of subsequent processes such as impregnation.

[0026] like Figure 4 and Figure 6 As shown, a drive assembly 3 is provided on a set of horizontal ends of the conveying guide rail 21. The drive assembly 3 is used to provide power for the installation part. Specifically, the drive assembly 3 includes a mounting base plate 31 fixed on both sides of a set of horizontal ends of the conveying guide rail 21. Multiple sets of bearing seats 32 are symmetrically fixed on the two sets of mounting base plates 31. A second contact wheel 33 is movably arranged between the two sets of oppositely arranged bearing seats 32. The second contact wheel 33 has a roller shaft, and the two ends of the roller shaft are movably arranged through the bearing seats 32 at both ends.

[0027] During actual operation, contact wheel 23 will contact contact wheel 29, and through friction and other forces, push the mounting part to move along the direction of the conveying guide rail 21, thereby realizing the conveying of the stator workpiece 27 within the equipment. Referring to the above figure, to ensure the stability and efficiency of this power transmission process, it should be noted that the combination of two sets of symmetrical bearing seats 32 and one set of contact wheel 23 is defined as a rotating unit. A sprocket 36 is fixed to one end of the roller shaft of each of the multiple rotating units. The sprockets 36 of adjacent rotating units are connected by a transmission chain 34. A drive motor 35 is fixed to the side of the mounting base plate 31, and this drive motor 35 is connected to one end of the roller shaft of one set of rotating units via a coupling.

[0028] After the drive motor 35 starts, it drives the roller shaft of the connected rotating unit to rotate. Then, through the cooperation of the sprocket 36 and the conveyor chain 34, the power is transmitted to the adjacent rotating units in sequence. Among them, the rotating unit located in the middle has multiple sets of sprockets 36 fixed on its roller shaft. This design can well adapt to the installation layout between adjacent rotating units, ensuring the continuity and stability of power transmission. This allows the drive assembly 3 to efficiently provide power support for the movement of the mounting part, ensuring that the stator workpiece 27 is transported smoothly and orderly on the conveyor guide rail 21, laying the foundation for the smooth progress of subsequent processes such as impregnation.

[0029] like Figures 1-3 As shown, an impregnation assembly 4 is provided below the mounting frame 12. The impregnation assembly 4 is used for the storage of paint and the impregnation of the stator in actual production. The impregnation assembly 4 includes an impregnation section provided below the mounting frame 12. The impregnation section includes an impregnation mother tank 41 provided below the mounting frame 12. The impregnation mother tank 41 is used to store paint and provide a sufficient source of paint for the impregnation process. Two sets of support brackets 422 are installed on the impregnation mother tank 41. The support brackets 422 are composed of horizontal and vertical rods. Impregnation sub-tanks 43 are fixed to the side of the vertical rod of the support brackets 422 by fasteners, so that the installation height of the impregnation sub-tanks 43 can be adjusted according to the size of the stator workpiece 27 and the impregnation depth required in actual production, thereby improving the versatility of the equipment.

[0030] The impregnation sub-tank 43 consists of storage area 1 431, storage area 2 432 and a sloping paint recovery plate 433 connected to one end of storage area 1 431 and storage area 2 432. Meanwhile, a conveying pump 42 is connected to the side of the impregnation mother tank 41. One end of the conveying pump 42 is connected to storage area 1 431 and storage area 2 432 through a conveying pipe 421.

[0031] In actual operation, the delivery pump 42 can transport the paint liquid stored in the impregnation tank 41 to storage area one 431 and storage area two 432 to ensure that there is enough paint liquid in storage area one 431 and storage area two 432 for impregnation. At the same time, level gauges are installed in both storage area one 431 and storage area two 432 to sense the amount of paint liquid in storage area one 431 and storage area two 432 and to always keep the paint liquid level at a specified height to ensure a stable impregnation effect of the stator workpiece 27.

[0032] When multiple sets of stator workpieces 27 mounted on the mounting shafts 25 at both ends of the rotating shaft 24 are conveyed to the sinking section 22 position by the drive assembly 3, the stator workpieces 27 on the mounting shafts 25 at both ends are immersed in storage area one 431 and storage area two 432 respectively. It should be noted that the stator workpieces 27 are partially immersed in paint, and there is a gap between storage area one 431 and storage area two 432. A connecting plate 434 is fixed within the gap, and the rotating shaft 24 is adapted to rotate on the connecting plate 434.

[0033] Meanwhile, two sets of friction parts 435 are fixed on both sides of the connecting plate 434. These friction parts 435 are elongated and arranged along the length of the conveying guide rail 21. The middle section of the friction part 435 has a downward tendency and adapts to the shape of the conveying guide rail 21, which helps to better cooperate with other transmission components during the movement of the component. The friction parts 435 can be made of materials with high friction coefficient and resistance to paint corrosion, such as rubber friction blocks, metal friction plates with anti-slip textures, or composite friction plates with wear-resistant resin coatings on the surface. These materials can ensure sufficient friction when in contact with the friction wheel 241 and resist paint corrosion, thus extending service life. At the same time, a friction wheel 241 is fixedly sleeved on the mounting shaft 25 between the stator workpiece 27 and the rotating shaft 24. The surface of the friction wheel 241 can be provided with fine anti-slip teeth to further improve the friction transmission effect with the friction parts 435.

[0034] During the actual impregnation process, the drive assembly 3 drives the mounting part (driving the mounting shaft 25 and the stator workpiece 27) to move towards the paint liquid in the impregnation tank 43. When the friction wheel 241 on the mounting shaft 25 comes into contact with the friction parts 435 on both sides of the connecting plate 434, as the drive assembly 3 continues to drive the mounting part to move smoothly, the static friction force generated between the friction wheel 241 and the friction part 435 will drive the friction wheel 241 to rotate slowly around the axis of the mounting shaft 25, thereby driving the mounting shaft 25 and the stator workpiece 27 fixed on it to rotate synchronously. At this time, the stator workpiece 27 is in the paint liquid in the impregnation tank 43. During the rotation, the iron core slots, windings and other parts of the stator workpiece 27 can be evenly contacted with the paint liquid, avoiding dead corners where the paint is not fully impregnated, and effectively improving the impregnation quality. Moreover, the drive component 3 can control the driving force and speed to ensure that the contact transmission speed between the friction wheel 241 and the friction part 435 is stable, and the stator workpiece 27 will not rotate too fast, thereby preventing the paint liquid from splashing due to excessive centrifugal force. This not only keeps the production environment clean, but also reduces paint liquid waste and lowers production costs.

[0035] like Figure 3 and Figures 7-8As shown, a processing component 5 is provided inside the support frame 11. This processing component 5 is used to process the recycled asphalt so that it can be returned to the impregnation tank 43. The processing component 5 includes a movable part fixed to the inner wall of the support frame 11. The movable part includes a mounting panel 52 horizontally arranged on the inner wall of the support frame 11. Parallel slide rails 54 and 56 are fixed on the mounting panel 52. Limiting blocks (not shown in the figure) are provided at both ends of slide rails 54 and 56. At the same time, a friction wheel 53 is provided on the mounting panel 52 between slide rails 54 and 56. A contact rod 55 is slidably arranged on slide rail 54, and a contact rod 57 is slidably arranged on slide rail 56. Both contact rods 55 and 57 are in close contact with the friction wheel 53.

[0036] In actual operation, when the contact rod 55 moves linearly under the action of an external force, it will drive the friction wheel 53 to rotate. Then, by utilizing the contact relationship between the friction wheel 53 and the contact rod 57, the contact rod 57 will move in the opposite direction, thus realizing the reverse movement of the two contact rods.

[0037] Furthermore, a reset part is provided on the mounting panel 52. From the perspective of the cyclic operation requirements of the equipment in actual production, the reset part is used to return the contact rod 57 to its initial position after the external force disappears, so as to facilitate the next operation. Referring to the figure above, the reset part includes a mounting corner block 58 fixedly mounted on the mounting panel 52 near one end. A reset spring 59 is fixed to the side of the mounting corner block 58, and one end of the reset spring 59 is connected to one end of the contact rod 57. When the contact rod 57 moves with the friction wheel 53, the reset spring 59 will be stretched or compressed.

[0038] In actual use, each of the three sets of mounting sections has a mounting shaft 25 with a contact wheel 514 threaded to one end. When the mounting section moves to the horizontal end near the right end, the contact wheel 514 contacts the contact rod 55 and simultaneously pushes the contact rod 55 to the right (see reference). Figure 7 Until one end of the contact rod 55 abuts against the limiting block, the external force between the contact wheel 514 of the mounting part and the contact rod 55 disappears. At this time, under the elastic force of the return spring 59, the contact rod 57 can smoothly return to its original position, preparing for the next cooperation with the contact wheel 514, and ensuring that the processing component 5 can continuously and stably process and recycle the asphalt.

[0039] Furthermore, a scraping section is provided on the second contact rod 57, which is used to scrape the asphalt on the asphalt recovery plate 433 back into the impregnation tank 43. The scraping section includes a right-angle rod 510 fixed to the side of the second contact rod 57, a concave frame 511 fixed to one end of the right-angle rod 510, and a scraper 512 movably disposed between the inner walls of the concave frame 511. Figure 7Based on this, a stop bar (not shown in the figure) is fixed to the inner wall of the concave frame 511 on the right side of the scraper 512.

[0040] During the actual paint scraping process, when the scraper 512 moves to the left synchronously with the contact rod 57, it is held vertically by the stop bar, allowing it to fully contact the bottom surface of the paint recovery plate 433. This scrapes the recovered paint back into the impregnation tank 43 along its slope, achieving paint recycling. When the scraper 512 returns to its original position and moves in the opposite direction, it is not constrained by the stop bar and tilts slightly. This prevents the paint already scraped back into the impregnation tank 43 from being scraped back onto the paint recovery plate 433, ensuring the effectiveness of paint recycling.

[0041] In this application, to achieve automated and precise control of equipment operation, a PLC control device is installed on the support frame 11. The PLC control device can adjust the speed and start / stop the drive motor 35 of the drive assembly 3 to ensure that the stator workpiece 27 is conveyed at a stable speed on the conveying guide rail 21, which meets the requirements of the conveying rhythm of the impregnation process. At the same time, it can control the operation of the conveying pump 42 and automatically start and stop the conveying pump 42 according to the paint liquid level signal fed back by the level gauge, so as to ensure that the paint liquid level in the impregnation tank 43 is stable.

[0042] Working principle: First, the stator workpiece 27 to be impregnated is fitted onto the mounting shaft 25 of the mounting part, and the stator workpiece 27 is fixed by the limiting part 26 to prevent it from slipping off. The drive motor 35 in the drive assembly 3 is started. The drive motor 35 drives the roller shaft of the connected rotating unit to rotate through the coupling. Then, with the help of the sprocket 36 and the transmission chain 34, the power is transmitted to the adjacent rotating unit, causing the contact wheel 2 33 to rotate. The contact wheel 2 33 contacts the contact wheel 29 on the mounting part, and the friction pushes the mounting part to move along the slide groove 23 of the conveying guide rail 21, thereby realizing the conveying of the stator workpiece 27 on the conveying guide rail 21.

[0043] When the stator workpiece 27 is conveyed to the lower section 22 of the conveying guide rail 21 along with the mounting part, a portion of the stator workpiece 27 will be immersed in the paint in the storage area 431 and storage area 432 of the impregnation sub-tank 43 in the impregnation assembly 4. Simultaneously, during the movement of the mounting part, the friction wheel 241 on the mounting shaft 25 contacts the friction part 435 on the connecting plate 434. Under the action of friction, the friction wheel 241 drives the mounting shaft 25 to rotate, thereby causing the stator workpiece 27 to rotate within the paint, ensuring that all parts of the stator workpiece 27 are evenly impregnated. During this process, the conveying pump 42 delivers the paint from the impregnation master tank 41 to the storage area 431 and storage area 432, and the level gauge monitors the paint level in real time to ensure that the paint level is at the specified height, providing a stable paint environment for impregnation.

[0044] After the impregnation is completed, the stator workpiece 27 continues to move with the mounting part, leaving the sinking section 22 and entering the paint-dip stage. Excess paint drips onto the paint-dip recovery plate 433 and flows down the slope to storage area 431 and storage area 432. When the mounting part moves to near the right horizontal end, the contact wheel 514 on the mounting part contacts the contact rod 55 in the processing assembly 5, pushing the contact rod 55 to the right along the slide rail 54. The contact rod 55 drives the friction wheel 53 to rotate, and the friction wheel 53 in turn drives the contact rod 57 to the left along the slide rail 56. The scraping part on the contact rod 57 moves synchronously.

[0045] When the scraping section moves, the scraper 512 remains vertical under the action of the stop bar, contacting the bottom surface of the paint recovery plate 433, scraping the residual paint on the paint recovery plate 433 back into the impregnation tank 43 along the slope. When the contact rod 55 abuts against the limit block of the slide rail 54, the external force between the contact wheel 514 and the contact rod 55 disappears. Under the elastic force of the return spring 59, the contact rod 57 drives the scraping section to reset. At this time, the scraper 512 is not constrained by the stop bar and tilts slightly to avoid scraping the scraped paint back onto the paint recovery plate 433, completing one paint recovery process. Afterward, the equipment repeats the above steps to continuously perform the impregnation operation of the stator workpiece 27. Example 2:

[0046] The above-mentioned motor stator impregnation process is as follows: Step 1: The stator workpiece 27 to be impregnated is fitted onto the mounting shaft 25 of the mounting part and fixed by the limiting part 26 to prevent slippage. The PLC control device starts the drive motor 35 of the drive assembly 3, which drives the contact wheel 2 33 to rotate through the coupling, sprocket 36 and conveyor chain 34. The contact wheel 2 33 contacts the contact wheel 1 29 of the mounting part, pushing the mounting part to move along the slide groove 23 of the conveying guide rail 21, thereby realizing the conveying of the stator workpiece 27.

[0047] Step Two: When the stator workpiece 27 is conveyed to the sinking section 22 of the conveying guide rail 21 along with the mounting section, it is partially immersed in the paint in storage area 431 and storage area 432 of the impregnation tank 43. Simultaneously, the friction wheel 241 on the mounting shaft 25 contacts the friction part 435 of the connecting plate 434. Under the action of friction, the friction wheel 241 drives the mounting shaft 25 to rotate, causing the stator workpiece 27 to rotate within the paint, achieving uniform impregnation. The PLC controls the conveying pump 42 to operate, and based on feedback from the level gauge, conveys the paint from the impregnation tank 41 to storage area 431 and storage area 432, maintaining a stable paint level.

[0048] Step 3: After the impregnation is completed, the stator workpiece 27 continues to move with the mounting part and enters the paint draining stage. Excess paint drips onto the paint draining recovery plate 433 and flows to the storage area. When the mounting part moves to near the right horizontal end, the contact wheel 3 514 of the mounting part contacts the contact rod 1 55 of the processing component 5, pushing the contact rod 1 55 to the right, driving the friction wheel 2 53 to rotate, causing the contact rod 2 57 to move to the left, and the scraping part on the contact rod 2 57 moves synchronously.

[0049] Step 4: When the scraping section moves, the scraper 512 remains vertical under the action of the stop bar, contacting the bottom surface of the paint recovery plate 433, scraping the residual paint back into the impregnation tank 43. When the contact rod 55 abuts against the limit block of the slide rail 54, the external force between the contact wheel 514 and the contact rod 55 disappears. Under the elastic force of the return spring 59, the contact rod 57 drives the scraping section to return to its original position, and the scraper 512 tilts slightly to prevent the scraped paint from returning to the paint recovery plate 433, thus completing the paint recovery. Afterward, the equipment repeats the above steps to continue the impregnation operation.
