Description

Technical Field

[0001] This invention relates to the field of motor stator assembly technology, specifically to a motor stator assembly equipment and assembly method. Background Technology

[0002] The stator of an AC motor is the stationary part of the motor. It is responsible for generating a rotating magnetic field and transmitting it to the rotor. AC current is passed through coils or windings to generate a rotating magnetic field, which forms a magnetic circuit with the rotor, driving the rotor to rotate and thus converting electrical energy into mechanical energy, or vice versa. The stator contains several windings, usually distributed in the slots of the stator core. The windings are used to connect to a three-phase AC power supply to generate a three-phase rotating magnetic field. The stator core is a magnetic core made of thin layers of silicon steel sheets, which reduces eddy current losses and improves magnetic flux utilization. Motor stator assembly refers to the process of assembling the stator core, windings, ends, connectors, and protective housing into a complete and operable stator assembly according to design requirements. This process includes inserting the windings into the conductor slots of the stator core.

[0003] The patent publication number CN117294096A describes a motor stator assembly device and process. It employs an adjustable height support assembly and an elastic support, and involves multiple heating cycles. The armature undergoes multiple sinking cycles until it is fully assembled with the housing. Each sinking distance is short, and the elastic force provides cushioning, allowing the armature to sink slowly and preventing tilting, ensuring proper installation with each sinking. After multiple sinking cycles, the armature and housing are successfully assembled. If the armature gets stuck during a sinking cycle, the support block can be removed to provide space, and then a jack can be used to push the adjustable height support assembly upwards to reposition the armature, allowing for reassembly or housing repair. In other words, this facilitates error correction and repair during assembly, preventing situations where the armature becomes stuck and cannot be separated, leading to scrapping.

[0004] In the process of assembling the windings of flat wire motors, as described above and similar technical solutions, the paper insertion step is omitted because the flat wire hairpins of the flat wire motor have an insulating coating on their surface. However, when protrusions or impurities appear inside the stator conductor slots due to processing reasons, the insulating coating on the surface of the flat wire hairpins will be damaged during the process of the flat wire hairpins entering the stator conductor slots. In severe cases, this can lead to premature insulation failure of the stator of the flat wire motor. Summary of the Invention

[0005] The purpose of this invention is to provide a motor stator assembly device and assembly method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a motor stator assembly equipment and assembly method, including a winding assembly and an outer clamping assembly and an inner clamping assembly for clamping the winding assembly, and further including a control assembly and a guide assembly for guiding gas flow. The outer clamping assembly includes an outer shell, the inner clamping assembly includes an inner shell, the control assembly includes a control rod body, the control rod body is connected to the inner shell, the control rod body is provided with a duct machine and a storage pipe, and the guide assembly is provided at the bottom of the storage pipe.

[0007] The storage pipe is equipped with a diversion pipe that communicates with the air duct machine. The diversion pipe is connected to the outer shell and the inner shell by a first air supply pipe and a second air supply pipe. A spray ring is installed at the bottom of the storage pipe, and a spray head is installed on the spray ring.

[0008] The guiding assembly includes a rotating shaft, which is rotatably connected to the storage pipe. An agitator is provided on the rotating shaft, and a first air jet hole and a second air jet hole are provided on the agitator. An air blowing pipe is provided on the outer shell. The rotating shaft is connected to the inner shell, and a guide fan blade is provided on the rotating shaft.

[0009] The air duct machine draws in and compresses air, which is then conveyed to the outer and inner housings to clamp the winding assembly. The spray head atomizes and sprays the material in the storage pipe. The first and second air jets drive the rotating shaft to rotate clockwise and counterclockwise, respectively. The stirring plate diffuses the atomized material, and the guide fan blades generate downward and upward converging airflow to assist in the diffusion and convergence of the atomized material. The blowing pipe blows the atomized material onto the surface of the winding assembly to form a protective layer.

[0010] Furthermore, a first air intake ring and a second air intake ring are sleeved on the rotating shaft. The first and second air intake rings are connected to the storage pipe. A first diversion valve and a second diversion valve are provided on the inner shell. Supply pipes are respectively connected between the first and second diversion valves and the first and second air intake rings. A partition is provided in the stirring plate. Multiple guide holes communicating with the stirring plate are opened on the rotating shaft. Air outlets are opened on the first and second air intake rings. A first jet hole is opened above the stirring plate, and a second jet hole is located below the stirring plate. Under the interception action of the partition, when the first diversion valve introduces compressed air into the first air intake ring, the air accumulates above the stirring plate and is ejected through the first jet hole, driving the rotating shaft and the stirring plate to rotate clockwise. The stirring plate diffuses the atomized material outward, forming a protective layer on the inner surface of the winding assembly. The atomized material is blown outward through the gaps between the winding components. The air blowing pipe blows the atomized material to the outer surface of the winding components to form a protective layer. The guide fan blades generate a downward diffusing airflow, accelerating the diffusion speed of the atomized material and improving the uniformity of spraying. When the second diverter valve introduces compressed air into the second intake ring, the air accumulates below the agitator plate and is ejected through the second jet hole, driving the rotating shaft and the agitator plate to rotate counterclockwise. The agitator plate diffuses the atomized material outward, forming a protective layer on the inner surface of the winding components. The atomized material is blown outward through the gaps between the winding components. The air blowing pipe blows the atomized material to the outer surface of the winding components to form a protective layer. The guide fan blades generate an upward converging airflow, gathering the atomized material upward. Combined with the outward diffusion of the agitator plate, a denser protective layer is formed on both the inner and outer surfaces of the winding components.

[0011] Furthermore, the outer shell has an outer groove, the inner shell has an inner groove, and the bottom of the outer shell has an outer hole communicating with the outer groove. The outer hole is connected to the air blowing pipe, which is equipped with a control valve that is electrically connected to the outer shell. The air blowing pipe blows compressed air from the outer groove toward the surface of the winding assembly. Under the adjustment of the control valve, the air flow rate is changed, thereby changing the diffusion effect on the atomized material.

[0012] Furthermore, the winding assembly includes flat wire hairpins with an insulating coating on their surface. The flat wire hairpins are in a fitted state. During assembly, multiple flat wire hairpins fall into the assembly mold in a predetermined order and are then clamped together in subsequent processes. They are moved to the stator above the stator to be installed, aligned with the stator wire slots, and then pushed into the stator wire slots together.

[0013] Furthermore, the outer shell and inner shell have multiple transverse slots, into which a first clamping rod and a second clamping rod are respectively inserted. A first return spring is provided between the first clamping rod and the outer slot, and a second return spring is provided between the second clamping rod and the inner slot. The first and second clamping rods are in sealed contact with the transverse slots. When compressed air enters the outer shell and inner shell, the internal pressure of the outer shell and inner shell increases. Under the action of gas pressure, the first and second clamping rods are pushed outward and clamp the winding assembly synchronously from the inside and outside. When the pressure disappears, under the action of the first and second return springs, the first and second clamping rods are pulled back into the outer shell and inner shell, and the process is reset.

[0014] Furthermore, both the first and second clamping rods are provided with locking blocks, which contact the outer groove and the inner groove respectively. Both the first and second clamping rods are provided with buffer blocks, which are made of rubber.

[0015] Furthermore, the material in the storage pipe is a water-based lubricant. The spray head atomizes and sprays the water-based lubricant. The first and second air jets drive the rotating shaft to rotate clockwise and counterclockwise, respectively. The stirring plate diffuses and atomizes the water-based lubricant spray. The guide fan blades generate downward and upward converging airflow to assist in the diffusion and convergence of the water-based lubricant spray. The blowing pipe blows the atomized material onto the surface of the winding assembly to form a water-based lubricant protective layer. Since the water-based lubricant can evaporate normally, the water-based lubricant protective layer will automatically evaporate after a period of time after the winding assembly is installed in the stator's wire slot, without affecting the operation of the motor.

[0016] Furthermore, the material in the storage pipe is a polycaprolactone composite solution. A heating wire is installed inside the control valve. The spray head atomizes and sprays the polycaprolactone composite solution. The first and second air jets drive the rotating shaft to rotate clockwise and counterclockwise, respectively. The stirring plate diffuses the polycaprolactone composite solution spray, and the guide fan blades generate downward and upward converging airflow to assist in the diffusion and convergence of the polycaprolactone composite solution spray. The blowing pipe blows the atomized material onto the surface of the winding assembly to form a polycaprolactone composite solution protective layer. Under the action of the heating wire, the gas blown out by the blowing pipe carries temperature, causing the polycaprolactone composite solution protective layer to expand slightly due to heat, forming an expansion layer that resists wear. Furthermore, during subsequent motor operation, the polycaprolactone composite solution protective layer can still absorb heat and expand, improving the stability of the winding.

[0017] Furthermore, the storage pipe is equipped with a feed pipe, and the top of the feed pipe is a sealed structure.

[0018] Furthermore, a method for assembling a motor stator, using the aforementioned motor stator assembly equipment, includes:

[0019] Protective materials are stored in the storage pipe. The air duct machine draws in air and compresses it, then delivers it to the outer shell and inner shell. The clamping winding assembly is fixed and clamped by the outer clamping assembly and the inner clamping assembly.

[0020] The spray head atomizes and sprays out the material in the storage tube. The first and second air jet holes drive the rotating shaft to rotate clockwise and counterclockwise, respectively. The stirring plate accelerates the diffusion of the atomized material and forms a protective layer on the inner surface of the winding assembly.

[0021] The guide fan blades generate downward and upward converging airflow to assist in the diffusion and convergence of atomized materials, while the air blowing pipe blows the atomized materials to the outer surface of the winding assembly to form a protective layer.

[0022] The clamped winding assembly is aligned with the stator conductor slot, and the winding assembly is pushed into the stator conductor slot to complete the installation of the winding assembly.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] The motor stator assembly equipment and method involve a spray head atomizing and spraying material from a storage pipe. When the first diverter valve introduces compressed air into the first air intake ring, the air accumulates above the agitator plate and is ejected through the first jet hole, driving the rotating shaft and agitator plate to rotate clockwise. The agitator plate diffuses the atomized material outward, forming a protective layer on the inner surface of the winding assembly, and blows the atomized material outward through the gaps between the winding assemblies. The air blowing pipe blows the atomized material to the outer surface of the winding assembly to form a protective layer. The guide fan blades generate a downward diffusion airflow, accelerating the diffusion speed of the atomized material and improving the uniformity of spraying.

[0025] Simultaneously, when the second diverter valve introduces compressed air into the second intake ring, the air accumulates below the agitator plate and is ejected through the second jet hole, driving the rotating shaft and the agitator plate to rotate counterclockwise. The agitator plate diffuses the atomized material outward, forming a protective layer on the inner surface of the winding assembly, and blows the atomized material outward through the gaps between the winding assemblies. The air blowing pipe blows the atomized material to the outer surface of the winding assembly to form a protective layer. The guide fan blades generate an upward converging airflow, converging the atomized material upward. Combined with the outward diffusion of the agitator plate, a denser protective layer is formed on the inner and outer surfaces of the winding assembly. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the assembly of flat wire motor windings, a significant advantage lies in the insulating coating inherent on the surface of the flat wire hairpin. This characteristic eliminates the need for the traditional paper insertion step, simplifying the assembly process and improving production efficiency. However, in actual operation, potential processing defects inside the stator conductor slots, such as protrusions or impurities, can damage the insulating coating when the flat wire hairpin enters the slot. If protrusions or impurities exist on the inner wall of the conductor slot, these minor flaws can become a hidden danger for damaging the insulating coating. When the flat wire hairpin is subjected to pressure or friction, its surface insulating coating may suffer wear, scratches, or even localized damage. Although these damages may not be immediately apparent, they can gradually become more noticeable over time. As the motor operates for a longer period of time, its potential hazards will gradually become apparent. The function of the insulating coating is to isolate the voltage between the conductors and prevent short circuits and leakage. Once the insulating coating is damaged, its insulation performance will be reduced, thereby weakening the motor's ability to withstand voltage surges. During motor operation, the conductors will generate heat, further accelerating the aging and deterioration of the insulation material. Under the dual effects of high voltage and high temperature, the damaged insulating coating is more likely to break down, leading to short circuits or leakage between the conductors, and ultimately causing insulation failure. At best, this will result in decreased motor performance, reduced efficiency, and unstable operation; at worst, it may cause the motor to burn out or even cause a safety accident.

[0038] like Figures 1-9 As shown, the present invention provides a technical solution: a motor stator assembly device, including a winding assembly 3 and an outer clamping assembly 1 and an inner clamping assembly 2 for clamping the winding assembly 3, and further including a control assembly 4 and a guide assembly 5 for guiding gas flow, characterized in that: the outer clamping assembly 1 includes an outer shell 101, the inner clamping assembly 2 includes an inner shell 201, the control assembly 4 includes a control rod body 401, the control rod body 401 is connected to the inner shell 201, a duct machine 403 and a storage pipe are provided on the control rod body 401, and the guide assembly 5 is provided at the bottom of the storage pipe; the storage pipe is provided with a connection to the duct machine 403. A three-way splitter pipe 404 is connected to the outer shell 101 and the inner shell 201. A first air supply pipe 405 and a second air supply pipe 406 are connected between the splitter pipe 404 and the outer shell 101 and the inner shell 201. A spray ring 407 is provided at the bottom of the storage pipe, and a spray head 408 is provided on the spray ring 407. The guide assembly 5 includes a rotating shaft 505, which is rotatably connected to the storage pipe. A stirring plate 506 is provided on the rotating shaft 505. A first air jet hole 507 and a second air jet hole 508 are opened on the stirring plate 506. An air blowing pipe 105 is provided on the outer shell 101. The rotating shaft 505 is connected to the inner shell 201. A guide fan blade 510 is provided on the rotating shaft 505.

[0039] It should be noted that the air duct 403 draws in and compresses air, which is then transported to the outer shell 101 and the inner shell 201 to clamp the winding assembly 3. The spray head 408 atomizes and sprays out the material in the storage tube. The first air jet 507 and the second air jet 508 drive the rotating shaft 505 to rotate clockwise and counterclockwise, respectively. The stirring plate 506 diffuses the atomized material, and the guide fan blades 510 generate downward and upward converging airflow to assist in the diffusion and convergence of the atomized material. The blowing pipe 105 blows the atomized material onto the surface of the winding assembly 3 to form a protective layer.

[0040] like Figures 7-9 As shown, a first air intake ring 503 and a second air intake ring 504 are sleeved on the rotating shaft 505. The first air intake ring 503 and the second air intake ring 504 are connected to the storage pipe. A first diversion valve 501 and a second diversion valve 502 are provided on the inner shell 201. The first diversion valve 501 and the second diversion valve 502 are respectively connected to the first air intake ring 503 and the second air intake ring 504 by supply pipes. A partition plate 509 is provided in the stirring plate 506. Multiple guide holes communicating with the stirring plate 506 are opened on the rotating shaft 505. Air outlet holes are opened on the first air intake ring 503 and the second air intake ring 504.

[0041] It should be noted that the first jet hole 507 is located above the agitator plate 506, and the second jet hole 508 is located below the agitator plate 506. Under the interception effect of the partition plate 509, when the first diverter valve 501 introduces compressed air into the first intake ring 503, the air accumulates above the agitator plate 506 and is ejected through the first jet hole 507, driving the rotating shaft 505 and the agitator plate 506 to rotate clockwise. The agitator plate 506 diffuses the atomized material outward, forming a protective layer on the inner surface of the winding assembly 3, and blows the atomized material outward through the gaps between the winding assemblies 3. The air blowing pipe 105 blows the atomized material to the outer surface of the winding assembly 3 to form a protective layer. The guide fan blade 510 generates a downward diffused airflow, accelerating the atomization of the material. To improve the diffusion speed and spray uniformity, when the second diversion valve 502 introduces compressed air into the second air intake ring 504, the air accumulates below the agitator plate 506 and is ejected through the second jet hole 508, driving the rotating shaft 505 and the agitator plate 506 to rotate counterclockwise. The agitator plate 506 diffuses the atomized material outward, forming a protective layer on the inner surface of the winding assembly 3, and blows the atomized material outward through the gaps between the winding assemblies 3. The air blowing pipe 105 blows the atomized material to the outer surface of the winding assembly 3 to form a protective layer. The guide fan blade 510 generates an upward converging airflow, converging the atomized material upward. Combined with the outward diffusion of the agitator plate 506, a denser protective layer is formed on the inner and outer surfaces of the winding assembly 3.

[0042] like Figures 4-5As shown, an outer groove 103 is opened inside the outer shell 101, and an inner groove 203 is opened inside the inner shell 201. An outer hole communicating with the outer groove 103 is opened at the bottom of the outer shell 101. The outer hole is connected to the air blowing pipe 105. A control valve 106 is provided on the air blowing pipe 105. The control valve 106 is electrically connected to the outer shell 101. The air blowing pipe 105 blows out the compressed air in the outer groove 103 and blows it toward the surface of the winding assembly 3. Under the adjustment of the control valve 106, the air flow rate is changed, thereby changing the diffusion effect on the atomized material.

[0043] like Figure 2 As shown, the winding assembly 3 includes a flat wire hairpin 301, the surface of which is provided with an insulating coating, and the flat wire hairpin 301 is in a mated state.

[0044] It should be noted that during assembly, multiple flat wire clips 301 fall into the assembly mold in a predetermined order, and are then clamped together in subsequent processes, moved to the stator to be installed, aligned with the stator wire slot, and pushed into the stator wire slot together.

[0045] like Figure 4 As shown, multiple transverse slots are formed on the outer shell 101 and the inner shell 201. A first clamping rod 102 and a second clamping rod 202 are respectively inserted into the transverse slots. A first return spring 104 is provided between the first clamping rod 102 and the outer slot 103, and a second return spring 204 is provided between the second clamping rod 202 and the inner slot 203. The first clamping rod 102 and the second clamping rod 202 are in sealed contact with the transverse slots.

[0046] It should be noted that when compressed air enters the outer shell 101 and the inner shell 201, the pressure inside the outer shell 101 and the inner shell 201 will increase. Under the action of gas pressure, the first clamping rod 102 and the second clamping rod 202 will be pushed outward and clamp the winding assembly 3 synchronously inside and out. When the pressure disappears, under the action of the first return spring 104 and the second return spring 204, the first clamping rod 102 and the second clamping rod 202 will be pulled back into the outer shell 101 and the inner shell 201, and the process will be reset.

[0047] like Figure 3 As shown, both the first clamping rod 102 and the second clamping rod 202 are provided with locking blocks, which contact the outer groove 103 and the inner groove 203 respectively. Both the first clamping rod 102 and the second clamping rod 202 are provided with buffer blocks, which are made of rubber.

[0048] It should be noted that when the first clamping rod 102 and the second clamping rod 202 move laterally and clamp the winding assembly 3, the locking block can limit the first clamping rod 102 and the second clamping rod 202 to prevent the first clamping rod 102 and the second clamping rod 202 from disengaging from the outer shell 101 or the inner shell 201. Furthermore, when clamping the winding assembly 3, the rubber buffer block can provide a flexible clamping effect to prevent damage to the insulating coating on the surface of the winding assembly 3.

[0049] In the specific implementation process, the material in the storage pipe is water-based lubricant. The spray head 408 atomizes and sprays the water-based lubricant. The first air jet 507 and the second air jet 508 drive the rotating shaft 505 to rotate clockwise and counterclockwise. The stirring plate 506 diffuses and atomizes the water-based lubricant spray. The guide fan blade 510 generates downward and upward converging air to assist in the diffusion and convergence of the water-based lubricant spray. The blowing pipe 105 blows the atomized material onto the surface of the winding assembly 3 to form a water-based lubricant protective layer. Since the water-based lubricant can evaporate normally, after the winding assembly 3 is installed into the stator wire slot, the water-based lubricant protective layer will automatically evaporate after a period of time and will not affect the operation of the motor.

[0050] In the specific implementation process, the material in the storage pipe is a polycaprolactone composite solution. The control valve 106 is equipped with a heating wire. The spray head 408 atomizes and sprays out the polycaprolactone composite solution. The first air jet 507 and the second air jet 508 drive the rotating shaft 505 to rotate clockwise and counterclockwise. The stirring plate 506 diffuses the polycaprolactone composite solution spray. The guide fan blade 510 generates downward and upward converging air to assist in the diffusion and convergence of the polycaprolactone composite solution spray. The air blowing pipe 105 blows the atomized material onto the surface of the winding assembly 3 to form a polycaprolactone composite solution protective layer. Under the action of the heating wire, the gas blown out by the air blowing pipe 105 carries temperature, causing the polycaprolactone composite solution protective layer to expand slightly due to heat, forming an expansion layer to resist wear. Furthermore, during subsequent operation of the motor, the polycaprolactone composite solution protective layer can still absorb heat and expand, improving the stability of the winding.

[0051] like Figure 1 As shown, a feed pipe 402 is provided on the storage pipe, and the top of the feed pipe 402 is a sealed structure.

[0052] A method for assembling a motor stator, using the aforementioned motor stator assembly equipment, includes: storing protective material in a storage pipe; drawing in and compressing air using a duct machine 403, and conveying it to the outer shell 101 and inner shell 201; clamping the winding assembly 3 using an outer clamping component 1 and an inner clamping component 2; a spray head 408 atomizing and spraying the material from the storage pipe; a first air jet 507 and a second air jet 508 driving a rotating shaft 505 to rotate clockwise and counterclockwise, respectively; a stirring plate 506 accelerating the diffusion of the atomized material, forming a protective layer on the inner surface of the winding assembly 3; a guide fan blade 510 generating downward and upward converging airflow to assist in the diffusion and convergence of the atomized material; and a blowing pipe 105 blowing the atomized material onto the outer surface of the winding assembly 3 to form a protective layer; aligning the clamped winding assembly 3 with the stator lead slot and pushing the winding assembly 3 into the stator lead slot to complete the installation of the winding assembly 3.

[0053] It should be noted that during assembly, multiple flat wire clips 301 fall into the assembly mold in a predetermined order and are subsequently clamped together, moved above the stator to be installed, aligned with the stator wire slots, and then pushed into the stator wire slots. The air duct unit 403 draws in air and compresses it, delivering it to the outer shell 101 and inner shell 201. The pressure inside the outer shell 101 and inner shell 201 increases. Under the action of gas pressure, the first clamping rod 102 and the second clamping rod 202 are pressed outwards respectively, and the winding assembly 3 is synchronously moved inside and out. When the pressure is released, under the action of the first return spring 104 and the second return spring 204, the first clamping rod 102 and the second clamping rod 202 will be pulled back into the outer shell 101 and the inner shell 201. The spray head 408 atomizes and sprays out the material in the storage tube. The first air jet hole 507 is opened above the stirring plate 506, and the second air jet hole 508 is set below the stirring plate 506. Under the interception action of the partition plate 509, when the first diversion valve 501 introduces compressed air into the first air intake ring 503, the air accumulates above the stirring plate 506 and passes through the first air intake ring 503. A jet nozzle 507 ejects air, driving the rotating shaft 505 and the agitator 506 to rotate clockwise. The agitator 506 diffuses the atomized material outward, forming a protective layer on the inner surface of the winding assembly 3, and blows the atomized material outward through the gaps between the winding assemblies 3. The air blowing pipe 105 blows the atomized material to the outer surface of the winding assembly 3 to form a protective layer. The guide fan blade 510 generates a downward diffused airflow, accelerating the diffusion speed of the atomized material and improving the uniformity of spraying. When the second diversion valve 502 introduces compressed air into the second air intake ring 504, the air accumulates under the agitator 506. The material is ejected through the second jet hole 508, driving the rotating shaft 505 and the stirring plate 506 to rotate counterclockwise. The stirring plate 506 diffuses the atomized material outward, forming a protective layer on the inner surface of the winding assembly 3. The atomized material is blown outward through the gaps between the winding assemblies 3. The air blowing pipe 105 blows the atomized material to the outer surface of the winding assembly 3 to form a protective layer. The guide fan blade 510 generates an upward converging airflow, converging the atomized material upward. Combined with the outward diffusion of the stirring plate 506, a denser protective layer is formed on the inner and outer surfaces of the winding assembly 3.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
