Description

Technical Field

[0001] This invention belongs to the field of stator processing, and particularly relates to stator processing equipment. Background Technology

[0002] The stator is the core component of an electric motor that generates a rotating magnetic field. A circular stator is usually assembled from multiple segmented stators. The manufacturing process of a circular stator requires the sequential completion of key steps such as inserting insulating paper, assembling the segmented stators into a circle, and welding them in place.

[0003] Currently, most of the above processes rely on independent semi-automatic equipment or extensive manual operation. Specifically, in the paper insertion process, operators need to manually align the insulating paper pieces one by one with the stator slots, and then use simple punching tools to press them into the slots. This process is difficult to align, labor-intensive, and the consistency of insertion depth and position is hard to guarantee. Each operation is time-consuming and extremely inefficient. After paper insertion, the stator needs to be manually transported to the rounding station, and then the segmented stator is brought together towards the center using manual or pneumatic clamps. This step requires a high level of operator experience, and uneven closing force can easily lead to stator roundness deviations. Moreover, only one workpiece can be processed at a time. After rounding, the stator is transferred to the welding station for fixed welding, which again involves manual clamping and positioning. This not only increases auxiliary time but also introduces cumulative positioning errors due to multiple clamping, affecting the consistency of the final product quality. It is evident that the existing stator processing methods have the following prominent problems: First, there is a lack of automated connection between the various processes, which relies heavily on manual intervention, resulting in slow production cycle, high labor costs, and low overall efficiency; Second, processes such as paper insertion, rounding, and welding are completed by different independent equipment or workstations, making it impossible to achieve the integration and continuous operation of multiple processes.

[0023] Please see Figures 1 to 21This application provides a stator processing device, including a support structure 10 with a support space 111 for accommodating a circular stator 200. The circular stator 200 has a paper insertion port 220 for inserting insulating paper 300. The paper insertion structure 20 includes a transfer plate 21 slidably disposed below the support structure 10 in a horizontal direction, a transfer mold 22 disposed on the transfer plate 21, and a pusher assembly 23 movably mounted on the transfer plate 21. The transfer mold 22 has a paper groove 221 for accommodating the insulating paper 300. The transfer plate 21 is used to drive the transfer mold 22 and the pusher assembly 23 to move to the support structure 10 and align the paper groove 221 with the paper insertion port 220. The pusher assembly 23 is used to push the insulating paper 300 located in the paper groove 221 into the paper insertion port 220. A lifting structure 30 is also provided. The lifting structure 30 is slidably disposed below the supporting structure 10 in a horizontal direction. After the insulating paper 300 is inserted into the paper insertion slot 220, it moves to the support space 111 and lifts the circular stator 200 upward so that the circular stator 200 is separated from the supporting structure 10. The circular welding assembly 70 includes a circular structure 710 spaced apart from the supporting structure 10, a welding structure 720 spaced apart from the circular structure 710, and a pressing structure 740 slidably disposed between the supporting structure 10 and the circular structure 710. The pressing structure 740 is used to pick up the circular stator 200 from the lifting structure 30 and transfer the circular stator 200 to the circular structure 710. The circular structure 710 is used to drive the circular stator 200 to close towards its center. The welding structure 720 is used to weld the circular stator 200.

[0024] In this embodiment, the circular stator 200 is composed of multiple segmented stators sequentially spliced ​​along the circumference. Insulating paper 300 needs to be inserted into the gap between two adjacent segmented stators, i.e., into the paper insertion slot 220, to achieve phase-to-phase insulation or slot insulation. In this embodiment, each segmented stator includes two segmented stator units 210, and the number of segmented stators is six, meaning that one circular stator 200 contains a total of twelve segmented stator units 210.

[0025] The supporting structure has a support space 111 for accommodating the circular stator 200. Specifically, the support space 111 is a circular cavity formed in the supporting structure 10 and open at the top and bottom. The diameter of the circular cavity is adapted to the outer diameter of the circular stator 200, allowing the circular stator 200 to be placed and positioned within it. When the circular stator 200 is placed in the support space 111, the paper insertion port 220 for inserting insulating paper 300 faces downwards, facilitating paper insertion from below. By providing a horizontally sliding lifting structure 30, after the insulating paper 300 is inserted and the transfer mold 22 is withdrawn, the lifting structure 30 can move to directly below the support space 111 and lift the circular stator 200 upwards, actively separating it from the supporting structure 10. This facilitates the retrieval of the circular stator 200 after paper insertion, improving the ease of material retrieval.

[0026] In this embodiment, when the circular stator 200 is placed on the upper surface of the support 712, the multiple segmented stator units 210 of the circular stator 200 are arranged in a ring structure. At this time, each segmented stator unit 210 rests on the support 712 by its own weight and rough positioning. There may be uneven radial gaps between them, and the mating surfaces of adjacent units are not tightly fitted, which is the "coarse circular" state. When the circular structure 710 forces all segmented stator units 210 to converge radially toward the center of the ring structure, the contact surfaces of adjacent segmented stator units 210 are finally tightly fitted, forming a complete, highly rounded annular stator core, which is the "fine circular" state. The welding structure 720 then welds two adjacent segmented stator units 210. The welding structure 720 can use a laser welding machine or an argon arc welding machine. Specifically, the welding structure 720 is a fiber laser welding machine, and its welding head can be fixedly mounted on a liftable bracket, which can adjust the focal length according to the weld position.

[0027] This application provides a support space 111 for the assembled stator 200 by setting a bearing structure 10, and uses a sliding transfer plate 21 to drive the transfer mold 22 to move, so that the paper slot 221 of the transfer mold 22 is precisely aligned with the paper insertion port 220, which allows the insulating paper 300 to be accurately inserted into the paper insertion port 220, improving the paper insertion accuracy. On this basis, the assembly structure 710 ensures the roundness of the assembled stator 200 after closing, providing a high-quality assembly foundation for subsequent welding, improving the welding quality and thus improving the overall processing quality of the stator. Furthermore, by setting up the paper insertion structure 20, the lifting structure 30, and the assembly welding assembly 70, and having them work together around the bearing structure 10, this application realizes the automatic alignment and insertion of the insulating paper 300, the automatic lifting and separation of the assembled stator 200, the automatic transfer, and the automatic assembly welding. The entire processing process is closely connected between each process and has a continuous cycle, avoiding the auxiliary time consumed by frequent manual handling and reclamping in traditional equipment, thereby significantly improving the processing efficiency of the stator.

[0028] Understandably, the embodiments of this application also include a control system (not shown in the figure). The supporting structure 10, the paper insertion structure 20, the lifting structure 30, and the round welding assembly 70 are all communicatively connected to the control system. The control system can control the automatic coordination and operation of the supporting structure 10, the paper insertion structure 20, the lifting structure 30, and the round welding assembly 70. The entire process is greatly automated through the automatic coordination and operation of the supporting structure 10, the paper insertion structure 20, the lifting structure 30, and the round welding assembly 70, which reduces manual operation and greatly improves production efficiency.

[0029] In some embodiments, such as Figure 3 and Figure 4As shown, the feeding assembly 23 includes a push rod 231 that slides vertically and a feeding driver 232 for driving the push rod 231 to move. The feeding driver 232 is connected to the transfer plate 21, and the push rod 231 is movably inserted through the paper slot 221. Since the push rod 231 is directly inserted inside the paper slot 221, the axis of movement of the push rod 231 always coincides with the center line of the paper slot 221, thereby ensuring that the pushing force applied by the push rod 231 to the insulating paper 300 is along the extension direction of the paper slot 221, i.e., the vertical direction. This effectively avoids the insulating paper 300 from lateral bending, folding, or jamming in the paper slot 221 due to the push rod 231 being skewed or the guide gap being too large, thus improving the paper insertion success rate.

[0030] In some embodiments, multiple paper insertion slots 220 are arranged at intervals, forming a ring structure along the circumference. Multiple paper slots 221 and push rods 231 are also arranged at intervals, with each paper slot 221 corresponding to one of each paper insertion slot 220, and each push rod 231 corresponding to one of each paper slot 221. Since the multiple paper slots 221 correspond one-to-one with the multiple paper insertion slots 220 in the circumferential position, the transfer plate 21 only needs to move horizontally once to align the transfer mold 22, and then the pusher driver 232 can drive the multiple push rods 231 to simultaneously insert insulating paper 300 into all paper insertion slots 220, thereby improving paper insertion efficiency.

[0031] In some embodiments, the transfer mold 22 is rotatably disposed on the transfer plate 21, and the paper insertion structure 20 further includes a rotary driver connected to the transfer plate 21; the stator processing equipment further includes a forming mechanism 60 for forming insulating paper 300, the forming mechanism 60 is arranged at intervals from the bearing structure 10, the forming mechanism 60 has a discharge port for outputting insulating paper 300, the transfer plate 21 is also used to drive the transfer mold 22 and the rotary driver to move to the forming structure 610, and the rotary driver is used to drive the transfer mold 22 to rotate so that each paper slot 221 corresponds to the discharge port and the insulating paper 300 at the discharge port falls into each paper slot 221 in sequence.

[0032] The forming mechanism 60 has a discharge port for discharging the formed insulating paper 300. The discharge port is downward-facing to facilitate the free fall or pushing of the formed insulating paper 300. When the intermediate transfer mold 22 is directly below the discharge port, the rotary driver drives the intermediate transfer mold 22 to rotate according to a preset program, so that one of the paper slots 221 on the intermediate transfer mold 22 is aligned with the discharge port. The forming mechanism 60 then outputs a sheet of formed insulating paper 300 from the discharge port, and the insulating paper 300 falls into the paper slot 221. Subsequently, the rotary driver drives the intermediate transfer mold 22 to rotate through a fixed angle, so that the next paper slot 221 is aligned with the discharge port, and the forming mechanism 60 outputs insulating paper 300 again, which falls into the paper slot 221. This cycle continues until all paper slots 221 are filled with insulating paper 300. The forming mechanism 60 only needs to be set with a fixed discharge port. The multiple paper slots 221 can be aligned with the discharge port in sequence to complete the filling by rotating the transfer mold 22 itself. This avoids the need to configure a separate forming mechanism 60 and discharge port for each paper slot 221, which greatly reduces equipment cost and floor space.

[0033] In some embodiments, such as Figure 3 As shown, the paper insertion structure 20 also includes a bracket connected to the transfer plate 21 and a guide plate 24 disposed on the bracket. The guide plate 24 is located below the transfer mold 22. The guide plate 24 has guide holes for the push rod 231 to pass through and guide the movement of the push rod 231. Multiple guide holes are arranged at intervals, and each guide hole corresponds to each push rod 231. It can be understood that when the length of the push rod 231 is large, it is difficult to effectively suppress the unstable bending of the push rod 231 under pressure by relying solely on the single-point guidance of the paper groove 221. The guide plate 24 and the paper groove 221 form a two-point support, which significantly increases the constraint length of the push rod 231 and ensures that the push rod 231 always maintains linear movement during the process of pushing the insulating paper 300.

[0034] In some embodiments, such as Figure 5 and Figure 6As shown, the supporting structure 10 includes a base 11 and multiple connectors 12. A supporting space 111 is disposed on the base 11, with open upper and lower sides. The circular stator 200 includes multiple segmented stators arranged circumferentially, with adjacent segmented stators forming paper insertion slots 220. Each connector 12 is detachably connected to each segmented stator. The connectors 12 are spaced apart circumferentially along the supporting space 111, and are slidably mounted on the base 11 radially along the supporting space 111 to adjust the distance between adjacent segmented stators. Understandably, the connectors 12 have detachable connection structures for clamping or adsorbing the segmented stators. These detachable connection structures can be vacuum suction cups, electromagnets, slots, or elastic claws, etc. In one specific embodiment, the connector 12 is fixed to the segmented stator by a snap-fit. When the circular stator 200 is driven by an external force to descend into the support space 111, the connector 12 is fixed to the segmented stator by a snap-fit. When the lifting structure 30 lifts the circular stator 200 and leaves the support space 111 through the upper opening, the lifting force on the circular stator 200 is greater than the bonding force between the connector 12 and the segmented stator, so the connector 12 separates from the segmented stator.

[0035] By actively separating adjacent stator segments radially outward before paper insertion, the gap in the paper insertion opening 220 is temporarily widened. The insulating paper 300 experiences almost no lateral pressure during insertion, thus preventing bending, wrinkling, surface coating scratches, or even breakage of the insulating paper 300 caused by forcibly pushing it into a narrow gap. After paper insertion, the connector 12 drives the stator segments to return radially inward, restoring the paper insertion opening 220 to its designed size. The insulating paper 300 is then tightly clamped using the elastic or rigid return force of the stator segments themselves.

[0036] In some embodiments, the stator clamping mechanism further includes an annular limiting member 13 rotatably connected to the base 11 and surrounding the support space 111. The inner wall of the annular limiting member 13 is provided with a plurality of driving surfaces 131, and each driving surface 131 corresponds to each connecting member 12. Each connecting member 12 elastically abuts against each driving surface 131. The driving surface 131 has a first abutting position 1311 and a second abutting position 1312 that abuts against the connecting member 12. The radial distance between the first abutting position 1311 and the center of the support space 111 is different from the radial distance between the second abutting position 1312 and the center of the support space 111, so that the annular limiting member 13 drives each connecting member 12 to slide synchronously along the radial direction of the clamping space 7113 during rotation.

[0037] The annular limiting member 13 is circular in shape, and its inner wall (i.e., the side facing the center of the support space 111) is machined with multiple driving surfaces 131. The number of driving surfaces 131 is equal to the number of connecting members 12, and they are arranged in a one-to-one correspondence along the circumference. Specifically, each driving surface 131 is a cam surface or inclined surface, that is, the radial distance between each point on the driving surface 131 and the center of the support space 111 changes continuously along the circumference. In this embodiment, the driving surface 131 is in the form of a curved surface: from the first abutting position 1311 to the second abutting position 1312, the radial distance of the driving surface 131 gradually increases or decreases. Specifically, when the annular limiting member 13 rotates to the first angle, the position where the connecting member 12 abuts is the first abutting position 1311, and the radial distance between this position and the center of the support space 111 is the first distance; when the annular limiting member 13 rotates to the second angle, the connecting member 12 abuts at the second abutting position 1312, and the radial distance is the second distance. The first distance and the second distance are not equal, and the difference between the two is the radial sliding stroke of the connector 12.

[0038] When all connectors 12 need to slide outward synchronously, the annular limiting member 13 is driven by an external force to rotate a preset angle in a first direction (e.g., clockwise). During the rotation, as the radial distance of the driving surface 131 gradually changes from the first contact position 1311 to the second contact position 1312, the connectors 12 always elastically adhere to the driving surface 131, thus being pushed by the driving surface 131 or allowed to be elastically pushed and moved radially outward. Since all driving surfaces 131 have the same contour and rotate synchronously, all connectors 12 obtain the same radial displacement, achieving synchronous outward sliding. Conversely, when the connectors 12 need to slide inward synchronously, the annular limiting member 13 rotates in the opposite direction by the same angle, and the driving surface 131 forces the connectors 12 to overcome the elastic force and move radially inward, returning to the initial position. Thus, only one drive source to drive the rotation of the annular limiting member 13 is needed to drive all connectors 12, eliminating the need for multiple cylinders and their corresponding solenoid valves, sensors, and controllers, significantly reducing the complexity and hardware cost of the electrical control system.

[0039] In some embodiments, the support structure 10 further includes an elastic element 14 connected to the base 11 and having an elastic restoring force. The elastic element 14 applies a force away from the center of the support space 111 to the connector 12, so that the connector 12 elastically abuts against the drive surface 131. Optionally, the elastic element 14 is a cylindrical helical spring. Since the elastic element 14 always pushes and pulls the connector 12 outward, the abutting end of the connector 12 can remain tightly against the drive surface 131 regardless of whether the annular limiting member 13 rotates clockwise or counterclockwise, without any backlash or lag due to changes in the direction of rotation. This ensures the accuracy and response speed of the radial position of the connector 12.

[0040] In some embodiments, the supporting structure 10 includes a base plate 711115 for supporting the base 11. The base plate 711115 has a hollow hole communicating with the support space 111 for the push rod 231 and the lifting structure 30 to pass through. A slider is connected to the bottom of the connector 12, and a groove 151 is provided on the top surface of the base plate 711115. The connector 12 is slidably mounted in the groove 151 via the slider. In addition, the outer edge of the annular limiting member 13 is provided with a toothed ring 132, and the base plate 711115 is provided with a motion driver 17. The motion driver 17 is connected to a rack 18, which meshes with the toothed ring 132. The motion driver 17 drives the rack 18 to reciprocate linearly, which can drive the annular limiting member 13 to rotate forward and backward around its axis. Optionally, the motion driver 17 is a stepper motor.

[0041] In some embodiments, such as Figure 3 As shown, the lifting structure 30 includes a sliding plate 31 that slides horizontally, push bars 32 that slide vertically, and a lifting driver 33 for driving the push bars 32 to move. The lifting driver 33 is connected to the sliding plate 31. The push bars 32 are used to lift the assembled circular stator 200. Multiple push bars 32 are arranged at intervals, and each push bar 32 is arranged in a ring structure along the circumference. Because multiple push bars 32 are distributed along the circumference, an upward force is applied to multiple symmetrical points at the bottom of the assembled circular stator 200 simultaneously during lifting, so that the assembled circular stator 200 as a whole bears a uniformly distributed load, avoiding relative slippage or gap changes between the segmented stators due to unilateral lifting.

[0042] In some embodiments, such as Figure 2 and Figure 3 As shown, the stator processing equipment also includes a transfer driver 40 for driving the transfer plate 21 to move. A sliding plate 31 is connected to the transfer plate 21, so that the transfer driver 40 drives the transfer plate 21 and the sliding plate 31 to move alternately under the support structure 10. The sliding plate 31 of this application can move horizontally along with the transfer plate 21, thereby saving the independent drive component originally used to drive the sliding plate 31 and significantly reducing equipment costs. Optionally, the sliding plate 31 and the transfer plate 21 are connected by a connecting rod 50. In other possible embodiments, the sliding plate 31 and the transfer plate 21 can also be connected by a connecting arm, a connecting plate, or a spherical bearing.

[0043] In some embodiments, the forming mechanism 60 includes: a paper pressing and conveying structure 620 for conveying insulating paper 300 and forming a first crease 310 and a second crease 320 on the surface of the insulating paper 300; a forming structure 610 including a first forming member 611, a second forming member 612, and a forming mold 613 having a forming cavity 6131, the forming cavity 6131 for receiving and accommodating the insulating paper 300, the first forming member 611 for cooperating with the forming cavity 6131 to bend the insulating paper 300 along the first crease 310, and the second forming member 612 for cooperating with the forming cavity 6131 to bend the insulating paper 300 along the second crease 320; and a paper cutting structure 680 disposed between the paper pressing and conveying structure 620 and the forming structure 610, the paper cutting structure 680 for cutting the insulating paper 300 entering the forming structure 610.

[0044] In this embodiment, the paper pressing and conveying structure 620, the paper cutting structure 680, and the forming structure 610 are arranged sequentially along the conveying direction of the insulating paper 300. The paper pressing and conveying structure 620 conveys the insulating paper 300 forward to a certain length (approximately equal to the length required for a finished product), and simultaneously presses out a first crease 310 and a second crease 320 on this section of insulating paper 300. The paper cutting structure 680 operates to cut the insulating paper 300 sheet with the first crease 310 and the second crease 320. The cut insulating paper 300 sheet is pushed into the forming cavity 6131 of the forming structure 610. The first forming component 611 operates to bend the insulating paper 300 along the first crease 310. The second forming component 612 operates to further bend the insulating paper 300 along the second crease 320 to obtain the final shape. Each forming component resets, and the formed insulating paper 300 is taken out or automatically fed out to enter the next cycle.

[0045] In this application, when the forming mechanism 60 performs the forming operation of the insulating paper 300, the paper pressing and conveying structure 620 pre-forms the first crease 310 and the second crease 320 precisely on the insulating paper 300. During forming, the first forming part 611 and the second forming part 612 respectively cooperate with the same forming cavity 6131 and bend along the predetermined crease. Since the crease and bending reference are unified and the forming process is completed in the same forming cavity 6131, the cumulative error caused by repositioning between multiple processes is avoided, which effectively improves the consistency of the formed shape. Furthermore, a paper cutting structure 680 is set between the paper pressing and conveying structure 620 and the forming structure 610, which can cut the insulating paper 300 to the required length before it enters the forming structure 610. The cut independent insulating paper 300 then enters the forming cavity 6131 for bending, which avoids the continuous insulating paper 300 pulling or interfering with each other during the bending process and improves the forming stability.

[0046] In some embodiments, the paper cutting structure 680 includes a slidably disposed cutter 681 and a cutting driver 682 connected to the cutter 681. The cutting driver 682 is used to drive the cutter 681 to move, so that the cutter 681 can move toward the insulating paper 300 and cut the insulating paper 300 through the blade of the cutter 681.

[0047] In some embodiments, such as Figure 9 , Figure 10 and Figure 11 As shown, the inner wall of the molding cavity 6131 is provided with a pressing groove 6132. The first fold 310 corresponds to the pressing groove 6132. The first molding part 611 is slidably disposed relative to the molding die 613. The first molding part 611 is driven by an external force to move toward the pressing groove 6132 and press the insulating paper 300 into the pressing groove 6132 along the first fold 310 so that the two sides of the first fold 310 are closed. It can be understood that the cross-sectional shape of the pressing groove 6132 can be V-shaped or U-shaped. The setting position of the pressing groove 6132 in the molding cavity 6131 corresponds precisely to the position of the first fold 310 pre-pressed on the insulating paper 300. The first molding part 611 can be set as a strip slider that matches the shape of the pressing groove 6132. The first molding part 611 is slidably disposed relative to the molding die 613, and its sliding direction is perpendicular to the plane of the insulating paper 300.

[0048] By setting a pressure groove 6132 in the forming cavity 6131 that precisely corresponds to the position of the first crease 310, and moving the first forming part 611 directly opposite the pressure groove 6132, the bending force is ensured to be accurately applied to the line of the first crease 310, effectively avoiding the problem of crease offset, improving the dimensional consistency of the forming of the insulating paper 300. Furthermore, as the first forming part 611 gradually presses the insulating paper 300 into the pressure groove 6132, the inner walls on both sides of the pressure groove 6132 provide support and guidance for the insulating paper 300, so that the material on both sides of the first crease 310 is evenly and slowly closed, reducing the risk of tearing of the insulating paper 300 due to local stress concentration.

[0049] In some embodiments, such as Figure 13 As shown, two second creases 320 are arranged at intervals, and the two second creases 320 are located on opposite sides of the first crease 310 respectively; the second forming part 612 includes forming part 6121, two forming parts 6121 are arranged at intervals, and the first forming part 611 is disposed between the two forming parts 6121. When the insulating paper 300 is pressed into the pressing groove 6132, the second forming part 612 is driven by external force to move toward the insulating paper 300 and cause the two forming parts 6121 to push the two sides of the insulating paper 300 respectively, so that the two sides of the insulating paper 300 are bent along the two second creases 320.

[0050] In this embodiment, after the insulating paper 300 is fed into the forming cavity 6131, the first forming member 611 is driven by an external force to move toward the pressing groove 6132, pressing the insulating paper 300 into the pressing groove 6132 along the first crease 310, so that the two sides of the first crease 310 are closed. At this time, the insulating paper 300 has a V-shaped or U-shaped outline, and the two side edges of the insulating paper 300 (i.e., the wings on both sides of the first crease 310) extend outwards into the pressing groove 6132, and the two second creases 320 are respectively located on these two extended parts. After the first forming member 611 is pressed in, it can remain in the pressing groove 6132, which plays a pressing role. Subsequently, the second forming part 612 is driven by external force to move towards the insulating paper 300. The two forming parts 6121 move simultaneously. When the two forming parts 6121 press against the two side edges of the insulating paper 300, the side edges are forced to bend further inward along the second crease 320 under the pressure of the forming parts 6121, forming a complex cross-sectional shape with two side bends. When the two forming parts 6121 press against the edges of the insulating paper 300 from both sides, the first forming part 611, positioned between them, provides central support and limits, preventing the insulating paper 300 from moving laterally as a whole, ensuring that the bending force is accurately applied to the second crease 320 line, and improving forming accuracy.

[0051] In some embodiments, the molding structure 610 further includes a molding fixing block 614 spaced apart from the molding mold 613, a molding portion 6121 connected to the molding fixing block 614 facing the surface of the molding mold 613, an elastic element 615 connected to the molding fixing block 614 facing the surface of the molding mold 613 and having elastic restoring force, a first driving member 616 connected to the molding fixing block 614, and a second driving member 617 connected to the first driving member 616. The elastic element 615 is disposed between the two molding portions 6121. The first molding member 611 is connected to one end of the elastic element 615 away from the fixing seat 7121. The opening of the molding cavity 6131 faces the molding fixing block 614. The first driving member 616 is used to drive the molding fixing block 614 to move toward or away from the molding cavity 6131. ​​The second driving member 617 is used to drive the molding fixing block 614 and the first driving member 616 to move toward or away from the molding cavity 6131.

[0052] In this embodiment, when the insulating paper 300 sheet with the first fold 310 and the second fold 320 is fed into the forming cavity 6131 and laid flat, the second driving member 617 is activated, driving the forming fixing block 614 and the first driving member 616 to move as a whole toward the forming cavity 6131. ​​As the whole moves, the first forming member 611 first contacts the first fold 310 position of the insulating paper 300. Due to the presence of the elastic element 615, the first forming member 611 presses the insulating paper 300 with elastic force. Next, the first driving component 616 is activated, driving the forming fixing block 614 to continue moving towards the forming cavity 6131. ​​At this time, since the elastic element 615 has been compressed and the first forming component 611 has pressed against the insulating paper 300, the first forming component 611 is blocked and cannot continue to move. Therefore, when the forming fixing block 614 continues to move, the elastic element 615 is further compressed, while the first forming component 611 remains stationary. At the same time, the forming fixing block 614 drives the two forming parts 6121 to move synchronously towards the insulating paper 300. Since the first forming component 611 is stationary, while the two forming parts 6121 continue to move forward, the front end of the forming part 6121 will push against the two side edges of the insulating paper 300, forcing the insulating paper 300 to bend along the two second folds 320. During the bending process, the first forming component 611 always presses the middle of the insulating paper 300 with elastic force, playing a stabilizing role.

[0053] The second driving component 617 feeds the first forming component 611 into the insulating paper 300 with elastic force, rather than directly impacting it rigidly. This avoids the first crease 310 from cracking due to instantaneous overload. After the second driving component 617 stops, the first forming component 611 is held in the middle of the insulating paper 300 by means of the elastic element 615, applying constant pressure. Meanwhile, the forming fixing block 614 continues to drive the forming part 6121 to move. This relative movement ensures that the middle part of the insulating paper 300 is firmly fixed when the two edges of the insulating paper 300 are bent, effectively preventing the insulating paper 300 from slipping or bulging. This ensures that the bending position of the two second creases 320 is accurate and the angle is consistent.

[0054] In some embodiments, the forming mold 613 has a feed port for the insulating paper 300 to enter the forming cavity 6131 and a discharge port for the insulating paper 300 to exit the forming cavity 6131. ​​The axis of the feed port and the axis of the discharge port are arranged in the same direction as the conveying direction of the insulating paper 300. The forming mechanism 60 also includes a pushing structure 630 disposed between the paper pressing and conveying structure 620 and the forming mold 613. The pushing structure 630 includes a paper pusher 631 slidably disposed along the conveying direction of the insulating paper 300 and a paper pusher driver 632 for driving the paper pusher 631 to move. The paper pusher 631 is movably disposed through the feed port and the discharge port to push the formed insulating paper 300 out of the forming cavity 6131 through the discharge port. Since the feed inlet and discharge outlet are coaxial and in the same direction as the conveying, the insulating paper 300 can enter, form and exit along a straight path. With the help of the pusher strip 631, the formed insulating paper 300 is pushed directly out of the discharge outlet, avoiding manual material handling or complex ejection components, and improving the cycle time of continuous automated production.

[0055] In some embodiments, the forming mechanism 60 further includes a shaping mold 640 disposed on the side of the forming mold 613 opposite to the pushing structure 630. The shaping mold 640 has a shaping cavity 641 through which the formed insulating paper 300 passes. The shaping cavity 641 is used to adjust the included angle between the insulating paper 300 segments on both sides of the second crease 320. Understandably, due to the elasticity of the insulating paper 300, the formed insulating paper 300 often rebounds, causing the actual included angle between the insulating paper 300 segments on both sides of the second fold 320 to be greater than the target included angle. For example, the target is 90°, but the actual angle is 95°~100°. The cross-section of the shaping cavity 641 is processed into a shape that matches the target included angle. When the pushing structure 630 pushes the formed insulating paper 300 through the shaping cavity 641, the inner wall of the shaping cavity 641 applies a continuous and gradual pushing force to the insulating paper 300 segments on both sides of the second fold 320 of the insulating paper 300, forcibly bringing the two insulating paper 300 segments together towards the middle, thereby precisely adjusting the included angle to the preset angle, for example, reducing it from 95° to 90°.

[0056] In some embodiments, such as Figure 9 and Figure 12As shown, the forming mechanism 60 also includes a guide structure 650 disposed between the paper pressing and conveying structure 620 and the forming mold 613. The guide structure 650 has a guide channel 651, the axis of which is aligned with the conveying direction of the insulating paper 300. The inlet of the guide channel 651 is connected to the outlet end of the paper pressing and conveying structure 620, and the outlet of the guide channel 651 is connected to the inlet. Because the axis of the guide channel 651 is aligned with the conveying direction, the guide structure 650 can accurately guide the insulating paper 300 into the inlet of the forming mold 613, ensuring that the first crease 310 and the second crease 320 on the insulating paper 300 maintain a preset alignment with features such as the pressing groove 6132 and the forming part 6121 in the forming cavity 6131, thereby improving forming consistency.

[0057] In some embodiments, the forming mechanism 60 further includes a support 661 connected to the guide structure 650 and a roller 662 rotatably connected to the support 661. The guide structure 650 has a notch 652 communicating with the guide channel 651. The outer peripheral surface of the roller 662 contacts the insulating paper 300 through the notch 652 to guide the conveying of the insulating paper 300. When the insulating paper 300 moves forward under the drive of the paper pressing and conveying structure 620 and enters the guide channel 651, the surface of the insulating paper 300 contacts the outer peripheral surface of the roller 662. Since the roller 662 can rotate freely, there is rolling friction between the insulating paper 300 and the roller 662, and its frictional resistance is small. At the same time, the roller 662 applies a slight downward pressure to the insulating paper 300. When the insulating paper 300 is driven forward, the roller 662 rotates accordingly, playing an auxiliary guiding and conveying role, so that the insulating paper 300 can pass through the guide channel 651 more smoothly and enter the feed port of the forming die 613.

[0058] In some embodiments, such as Figure 8 As shown, the paper pressing and conveying structure 620 includes a base 621, a first roller 622 rotatably connected to the base 621, and a second roller 623 rotatably connected to the base 621. The rotation axis of the first roller 622 is parallel to the rotation axis of the second roller 623. The insulating paper 300 is clamped between the first roller 622 and the second roller 623, and the first roller 622 is used to drive the second roller 623 to rotate, thereby driving the conveying of the insulating paper 300. The first roller 622 is provided with a protruding ridge 7131, and the second roller 623 is provided with a groove that mates with the protruding ridge 7131. The protruding ridge 7131 is used to press the insulating paper 300 into the groove to press out the first crease 310 and the second crease 320 on the insulating paper 300. By integrating the creasing function into the conveying roller, the separate creasing station and drive mechanism are eliminated. The insulating paper 300 naturally completes the crease pressing during the conveying process without additional dwell time, improving production efficiency and reducing the overall size of the machine.

[0059] Optionally, the paper pressing and conveying structure 620 further includes a first gear 624 connected to the first roller 622, a second gear 625 connected to the second roller 623, and a rotary driver 626 for driving the first roller 622 to rotate. The second gear 625 meshes with the first gear 624, so when the rotary driver 626 drives the first roller 622 to rotate, the second roller 623 can also rotate under the transmission action of the first gear 624 and the second gear 625.

[0060] In some embodiments, to achieve continuous, stable, and automated feeding of the insulating paper 300, the forming mechanism 60 further includes a roll mechanism 671 disposed upstream of the paper pressing and conveying structure 620. The rolled insulating paper 300 is sleeved on the roll shaft of the roll mechanism 671 and can rotate freely around the shaft, thereby realizing the rotation and unwinding of the roll and guiding the insulating paper 300 towards the paper pressing and conveying structure 620. Optionally, the roll mechanism 671 and the paper pressing and conveying structure 620 are also provided with a clamping mechanism 672. The clamping mechanism 672 includes two rotatably disposed paper belt pulleys 6721. The insulating paper 300 is clamped between the two paper belt pulleys 6721. After the insulating paper 300 is clamped, a section of insulating paper 300 with stable tension is formed on the side of the paper belt facing the paper pressing and conveying structure 620.

[0061] In some embodiments, the circular structure 710 includes a turntable 711 rotatably disposed about a preset axis and provided with a clamping space 7113, a support seat 712 disposed in the clamping space 7113 and used to support a plurality of segmented stator units 210, and a pusher block 713 slidably disposed in the clamping space 7113 along the radial direction of the clamping space 7113. Each segmented stator unit 210 is arranged in a ring structure along the circumference of the support seat 712. A plurality of pushers 713 are arranged at intervals along the circumference of the clamping space 7113, and each pusher block 713 corresponds one-to-one with each segmented stator unit 210. Each pusher block 713 is used to push each segmented stator unit 210 to move radially toward the center of the ring structure along the clamping space 7113, so that each segmented stator unit 210 closes.

[0062] In this embodiment, a circular recessed cavity is formed on the upper surface of the turntable 711, which constitutes a clamping space 7113. The diameter of the clamping space 7113 is slightly larger than the outer diameter formed by the closing of all the segmented stator units 210, so as to accommodate the segmented stator units 210. When each pusher 713 moves towards the center of the clamping space 7113, the pushing surface of each pusher 713 contacts and pushes the outer wall of the corresponding segmented stator unit 210, forcing all segmented stator units 210 to close radially towards the center of the annular structure. Finally, the contact surfaces of adjacent segmented stator units 210 are tightly fitted to form a complete, highly rounded annular stator core. When the turntable 711 drives the segmented stator units 210 to rotate, the weld between two adjacent segmented stator units 210 will pass directly below the weld head of the welded structure 720.

[0063] The circular welding device of this application has multiple push blocks 713 that slide radially along the clamping space 7113 and correspond one-to-one with each segmented stator unit 210. Each push block 713 can push the corresponding segmented stator unit 210 to move radially, thereby making all segmented stator units 210 tightly closed. This achieves precise positioning of the segmented stator units 210, ensuring the roundness of the ring structure formed by the segmented stator units 210 after closure and the fit of the contact surfaces of adjacent segmented stator units 210. This provides a high-quality assembly foundation for subsequent welding and improves welding quality. Furthermore, by setting a turntable 711 that rotates around a preset axis, the turntable 711 can drive the entire ring structure to rotate sequentially after the segmented stator units 210 are closed, so that each welding position between two adjacent segmented stator units 210 is sequentially aligned with the welding structure 720 arranged at intervals. The entire process does not require manual adjustment of the welding position, reducing manual intervention and thus improving welding efficiency. In some embodiments, multiple welding structures 720 are arranged at circumferential intervals along the turntable 711, and each welding structure 720 can be welded, thereby improving welding efficiency.

[0064] In some embodiments, such as Figure 15 and Figure 16As shown, the turntable 711 includes a rotatable chassis and mounting seats 7112 connected to the base plate 711115. Multiple mounting seats 7112 are spaced apart along the circumference of the chassis, forming a clamping space 7113. A support seat 712 is located in the central area of ​​the chassis. The circular structure 710 also includes multiple sliding drive components 714 respectively mounted on each mounting seat 7112. The sliding drive components 714 drive the push blocks 713 to move, and each sliding drive component 714 corresponds one-to-one with each push block 713. The chassis and each mounting seat 7112 can be machined independently, reducing the manufacturing difficulty and cost of the large-size integral turntable 711. The mounting seats 7112 can be bolted to the chassis, and their positions can be finely adjusted, which helps ensure the circumferential angular accuracy of each push block 713. Optionally, the chassis is connected to the rotary drive component 716626, which drives the chassis to rotate. Specifically, the rotary drive component 716626 can be a rotary platform or a servo motor. Optionally, the sliding drive component 714 can be a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0065] In some embodiments, such as Figure 16 and Figure 17 As shown, the circular structure 710 also includes a sliding seat 715 connected to the chassis. The sliding seat 715 is located between the support seat 712 and the mounting seat 7112. The sliding seat 715 has a guide groove for the push block 713 to pass through, thereby guiding the sliding path of the push block 713. Multiple sliding seats 715 are arranged at intervals along the circumference of the clamping space 7113, and each sliding seat 715 corresponds to each push block 713. In this embodiment, the axial direction of the guide groove is strictly parallel to the radial direction of the clamping space 7113, and the cross-sectional shape of the guide groove matches the cross-sectional shape of the push block 713, such as a rectangular groove, a T-shaped groove, or a dovetail groove. The push block 713 moves linearly in the radial direction under the constraint of the guide groove, and its movement path is precisely defined. By setting guide grooves, the movement direction of push blocks 713 can be corrected, ensuring that each push block 713 moves strictly along the radial direction, thereby ensuring that the thrust direction of each segmented stator unit 210 is accurately pointed to the center of the annular structure, further improving the roundness and consistency of the precision assembly.

[0066] In some embodiments, such as Figure 17 As shown, the push block 713 has a protruding ridge 7131 on its surface facing the segmented stator unit 210, and the outer wall of the segmented stator unit 210 has a groove that matches the protruding ridge 7131. The protruding ridge 7131 is used to engage with the groove. The engagement of the protruding ridge 7131 with the groove keeps the push block 713 and the segmented stator unit 210 in a fixed relative position, effectively avoiding circumferential misalignment of the segmented stator unit 210 due to inertial forces during radial closing or when the turntable 711 starts rotating. This effectively improves the alignment accuracy of the joints between adjacent segmented stator units 210, thereby improving the welding quality.

[0067] In some embodiments, the assembly welding apparatus further includes a linear movement mechanism 730 for driving the pressing structure 740 to move in three-dimensional space. The pressing structure 740 is used to release the assembly stator 200 onto the support seat 712, which elastically supports each segmented stator unit 210. The linear movement mechanism 730 is also used to drive the pressing structure 740 to press each segmented stator unit 210 downwards so that the top surfaces of each segmented stator unit 210 are at the same height.

[0068] The linear movement mechanism 730 drives the pressing structure 740 to move directly above the support seat 712 of the turntable 711, aligning each segmented stator unit 210 with the support area of ​​the support seat 712. The pressing structure 740 then descends to place each segmented stator unit 210 on the upper surface of the support seat 712. Before or simultaneously with the radial precision rounding of the push block 713, the linear movement mechanism 730 drives the pressing structure 740 to descend, causing the lower plane of the pressing structure 740 to contact the top surface of each segmented stator unit 210. The pressing structure 740 continues to apply downward pressure, overcoming the elastic force of the elastic support member. Because the lower plane of the pressing structure 740 is a flat plane, the top surfaces of all segmented stator units 210 are forced to the same horizontal height. At this point, each segmented stator unit 210 achieves a precise and consistent position in the height direction. After the push block 713 clamps, the pressing structure 740 can rise and retract to avoid interfering with subsequent welding rotation. By aligning the top surfaces of all segmented stator units 210 to the same horizontal plane, the penetration depth and width of each weld can be made uniform, thereby improving the welding quality.

[0069] In some embodiments, such as Figure 18 As shown, the support base 712 includes a fixed base 7121 and multiple push rods 7122 slidably disposed on the fixed base 7121 in the vertical direction. The top surface of the fixed base 7121 has multiple insertion holes, and each push rod 7122 is inserted into its respective insertion hole. The bottom wall of each insertion hole is provided with an elastic device 7123. One end of the elastic device 7123 is connected to the bottom end of the push rod 7122, and the other end is connected to the bottom wall of the insertion hole, so that each push rod 7122 provides elastic support to each segmented stator unit 210. Each segmented stator unit 210 is supported by an independent push rod 7122 and elastic device 7123, and its support height and stiffness can vary independently. When each segmented stator unit 210 has a thickness tolerance, after the pressing structure 740 is tightened, units of different thicknesses will force the corresponding push rods 7122 to compress to different depths, thereby ensuring that the top surfaces of all segmented stator units 210 are flush. Optionally, the elastic element 7123 is a spring.

[0070] In some embodiments, the linear motion mechanism 730 includes a first lifting driver 732 and a linear module 731 for driving the first lifting driver 732 to move horizontally. The first lifting driver 732 drives the pressing structure 740 to move vertically. The long-stroke horizontal movement and the short-stroke vertical pressing action are handled by two independent actuators, resulting in clear control logic and reducing the development difficulty and cost of the control system. Optionally, the first lifting driver 732 is an electric cylinder or a cylinder with a position sensor.

[0071] In some embodiments, such as Figure 19 As shown, the pressing structure 740 includes a connecting seat 741 connected to the first lifting drive 732, grippers 742 slidably disposed on the connecting seat 741, and a pressing head 743 connected to the bottom end of the connecting seat 741. The pressing head 743 is used to press down each segmented stator unit 210. Multiple grippers 742 are arranged at intervals around the pressing head 743. Each gripper 742 can slide towards or away from each other to grip or release each segmented stator unit 210. Understandably, the grippers 742 can provide a large gripping force. During the rapid acceleration, deceleration, or movement of the linear motion mechanism 730, the grippers 742 can reliably maintain the gripping of the segmented stator unit 210, resulting in high safety. Furthermore, the pressure head 743 and the gripper 742 are functionally separate and operate flexibly. The pressure head 743 is dedicated to pressing down and leveling, while the gripper 742 is dedicated to picking up and releasing. The two can be controlled independently. For example, during the precision rounding process, the gripper 742 can remain open and not contact the workpiece, while the pressure head 743 continuously applies downward pressure.

[0072] In some embodiments, the center of the pressure head 743 is also connected to a spindle 744, and each segmented stator unit 210 is arranged around the spindle 744. The spindle 744 enables each segmented stator unit 210 to be constrained in the radial direction, thereby initially forming a ring structure.

[0073] Optionally, the radial sliding of each gripper 742 is driven by a gripper 742 driver disposed inside the connecting seat 741. Specifically, the gripper 742 driver is in the form of a combination of a cylinder and a wedge mechanism, for example, a vertically arranged small cylinder converts the vertical motion into the radial horizontal motion of the gripper 742 through a wedge slider. In other possible embodiments, the radial sliding of each gripper 742 may also be driven by its own independent driver.

[0074] In some embodiments, the linear motion mechanism 730 further includes a second lifting driver 733 connected to the output end of the linear module 731 and a dust collection assembly 750 connected to the second lifting driver 733. The linear module 731 is used to drive the second lifting driver 733 to move horizontally, and the second lifting driver 733 is used to drive the dust collection assembly 750 to move vertically. Figure 7As shown, the dust collection assembly 750 includes a dust collection hood 751 for covering the upper end of each segmented stator unit 210 and an air suction pipe 752 communicating with the inner cavity of the dust collection hood 751. The bottom of the dust collection hood 751 is open, and the side wall of the dust collection hood 751 is provided with a plurality of clearance notches 7511652. The clearance notches 7511652 are used for welding the segmented stator units 210 by the welding structure 720. The air suction pipe 752 is used to guide the welding fumes to the external space.

[0075] After the precision assembly is completed and the pressing structure 740 is removed, the linear module 731 drives the second lifting driver 733 and the dust collection component 750 to move horizontally to directly above the support base 712. The second lifting driver 733 drives the dust collection hood 751 to descend vertically until the bottom edge of the dust collection hood 751 approaches the upper surface of the turntable 711, so that the dust collection hood 751 covers the entire assembled segmented stator unit 210. At this time, each clearance notch 7511652 is aligned with the predetermined position of each weld seam, thereby avoiding affecting the welding, effectively collecting welding fumes, improving the working environment, and protecting the health of operators.

[0076] In some embodiments, the stator processing equipment further includes a marking structure 80 spaced apart from the circular assembly structure 710 and a unloading robot 760 slidably disposed between the circular assembly structure 710 and the marking structure 80. The unloading robot 760 is used to pick up the circular assembly stator 200 welded at the circular assembly structure 710 and transfer it to the marking structure 80, which is used to mark the circular assembly stator 200. Optionally, the unloading robot 760 can be connected to the linear motion mechanism 730.

[0077] In some embodiments, such as Figure 21 As shown, the marking structure 80 includes a central transfer base 81, a material transfer module 82, a rotary table 83 spaced apart from the central transfer base 81, and a laser marking machine 84 spaced apart from the rotary table 83. The central transfer base 81 is used to receive the circular stator 200 at the unloading robot 760. The material transfer module 82 is used to pick up the circular stator 200 at the central transfer base 81 and move it to the rotary table 83. The rotary table 83 is used to drive the circular stator 200 so that each marking position on the circular stator 200 corresponds to the laser marking machine 84. The laser marking machine 84 performs laser marking on the circular stator 200, and after the marking and scanning are completed, the material transfer module 82 unloads the circular stator 200.

[0078] In some embodiments, the circular welding assembly 70 further includes a detection structure 770 connected to the linear motion mechanism 730. The unloading robot 760 moves synchronously with the detection structure 770. The detection structure 770 is used to detect whether the paper insertion quality of the circular stator 200 in the supporting structure 10 is qualified. Circular stators 200 that fail the detection can be unloaded by the unloading robot 760 to the unqualified conveyor line. Optionally, the supporting structure 10 is a camera. Additionally, the stator processing equipment also includes an inspection assembly 90 arranged at intervals from the supporting structure 10. The inspection assembly 90 is used to inspect the detection structure 770. Specifically, the inspection assembly 90 includes a qualified product and a unqualified product. Before startup, the linear motion mechanism 730 drives the detection structure 770 to take pictures of both the qualified and unqualified products. By observing whether the unloading robot 760 moves to the unqualified conveyor line or the circular welding assembly 70, the integrity of the detection function of the detection structure 770 is determined.
