Description

Technical Field

[0001] This invention belongs to the field of motor stator winding processing technology, and relates to an integrated machine structure, particularly a two-winding-one-embedded integrated machine structure. Background Technology

[0002] In the field of motor stator winding processing, the two-winding-one-insertion integrated machine is the core equipment for realizing the integrated operation of coil winding, slot wedge installation and wire insertion. Among them, the operating accuracy and efficiency of the paper feeding device (slot wedge feeding mechanism) directly affect the insulation performance, wire insertion quality and overall production cycle of the stator winding. As a key component for the insulation and fixation of the stator slot, the slot wedge needs to be accurately embedded in the stator core slot. The stability of its paper feeding, forming, indexing positioning and pushing insertion is the core to ensure processing quality.

[0003] The paper loading devices of existing two-winding-one-insertion integrated machines generally suffer from numerous technical defects, making it difficult to meet the demands of high-efficiency and high-precision production. Firstly, traditional paper feeding mechanisms often employ a single roller friction drive or pneumatic pushing method, resulting in uneven power transmission during paper feeding. This easily leads to paper slippage, jamming, or deviations in paper feeding length, causing mismatches between the slot wedge size and the wire groove, affecting insulation performance. Simultaneously, the paper feed channel is mostly designed as a straight line, resulting in poor alignment with the slot wedge magazine of the feed cylinder. Wrinkles and deformation easily occur during paper feeding, reducing the quality of slot wedge forming. Secondly, the forming structure design is unreasonable, lacking targeted roll forming components. The paper is formed solely by extrusion through the feed channel, resulting in low forming accuracy and poor consistency in the slot wedge cross-sectional shape, making it difficult to adapt to the installation requirements of stator wire grooves of different specifications. Thirdly, the indexing and positioning of the feed cylinder and the linkage between the station switching mechanism are poor, often relying on manual assistance or simple cylinder pushing. This results in low indexing rotation accuracy, and the feed cylinder is prone to offset during station switching, causing misalignment between the slot wedge magazine and the paper feeding and pushing mechanisms, affecting paper feeding and insertion accuracy.

[0004] Furthermore, traditional paper pushing assemblies often employ a single pusher or a single-sided drive structure, resulting in uneven force distribution during the pushing process. This can easily lead to pusher swaying or jamming, causing the slot wedge to be pushed incompletely or embedded at an angle, and even scratching the inner wall of the slot. Some devices lack reliable guiding and synchronous transmission structures, resulting in insufficient pushing stability and further reducing the consistency of slot wedge embedding. Fourthly, the paper cutting assembly and paper feeding mechanism are not coordinated, and the timing of paper cutting is mismatched with the paper feeding speed, easily leading to errors in paper cutting length or paper breakage. Moreover, paper pieces are prone to remain in the material channel after cutting, affecting the continuity of subsequent paper feeding operations. At the same time, the integration level of the components in existing paper loading devices is low, and the processes of paper feeding, forming, indexing, and pushing are not smoothly connected. The equipment has poor versatility, requiring the replacement of multiple sets of parts for different stator specifications, resulting in low changeover efficiency and hindering the improvement of overall production efficiency.

[0005] To solve the above technical problems, it is urgent to develop a paper loading device with a high degree of integration, precise paper feeding and forming, reliable indexing and positioning, and stable pushing. By optimizing the paper feeding and forming structure, indexing transmission mechanism and paper pushing synchronous design, the entire process of slot wedge feeding and loading can be automated and precisely controlled, thereby improving the overall processing quality and production efficiency of the two-winding-one-insertion integrated machine. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a two-winding-one-embedding integrated machine structure. It solves the technical problem of how to develop a paper loading device with a high degree of integration, precise paper feeding and forming, reliable indexing and positioning, and stable pushing.

[0007] The objective of this invention can be achieved through the following technical solutions: A two-winding-one-insertion integrated machine structure includes a winding device, a paper loading device, and an inserting device. The paper loading device includes a frame, a paper feeding and forming assembly, and a paper pushing assembly. The frame has a paper feeding station and a paper pushing station. The paper feeding and forming component is located at the paper feeding station, and the paper pushing component is located at the paper pushing station. The frame is provided with a material cylinder that can reciprocate between the paper feeding station and the paper pushing station. The material cylinder is provided with an indexing structure that can drive the material cylinder to rotate. The paper feeding and forming assembly includes a paper feed channel and two opposing gears. The outlet of the paper feed channel corresponds to the groove on the feed cylinder. The middle section of the paper feed channel has a notch. The two gears are located at the notch and are respectively located on both sides of the paper sheet passing through. The paper sheet is driven to output by friction formed by the rotation of the gears. This paper loading device also includes a paper cutting assembly, which is located near the paper feed outlet and is used to cut continuous sheets of paper. The paper pushing assembly includes a push rod and a drive assembly, the drive assembly driving the push rod to move upward to push the paper at the bottom of the barrel completely into the slot.

[0008] In the above-mentioned two-winding-one-embedding integrated machine structure, the paper feed channel has an arc-shaped structure and includes a straight section and an arc section. The straight section is vertically arranged and its end corresponds to the position of the grooved groove of the feed cylinder to form an upward paper feeding grooved groove.

[0009] In the above-mentioned two-winding-one-embedding integrated machine structure, the teeth of the two gears are stepped to cooperate with the paper rolling forming.

[0010] In the above-mentioned two-winding-one-embedding integrated machine structure, the paper feeding and forming component further includes a servo motor, which outputs power in cooperation with one of the gear transmissions.

[0011] In the above-mentioned two-winding-one-embedding integrated machine structure, a linear slide rail is arranged between the paper feeding station and the paper pushing station on the frame. A tray is slidably connected on the linear slide rail. The material cylinder and the indexing structure are both installed on the tray, and an avoidance position is opened on the tray corresponding to the bottom of the material cylinder.

[0012] In the above-mentioned two-winding-one-embedding integrated machine structure, the indexing structure includes a second servo motor and an annular toothed part located in the circumferential direction of the material cylinder. The second servo motor and the annular toothed part are connected and driven by a synchronous belt, and the material cylinder is driven to rotate indexing by the second servo motor.

[0013] In the above-mentioned two-winding-one-embedding integrated machine structure, a long-distance cylinder is fixed on the frame, and the push rod of the long-distance cylinder is connected to the tray to drive the tray to reciprocate between the paper feeding station and the paper pushing station.

[0014] In the above-mentioned two-winding-one-embedding integrated machine structure, the push rod is fixed on the sliding seat, the opposite ends of the sliding seat are respectively slidably connected to the guide shaft, and the guide shaft is fixed on the frame to increase the pushing stability.

[0015] In the above-mentioned two-winding-one-embedding integrated machine structure, the sliding seat has connecting parts at opposite ends, and each connecting part is threaded with a lead screw. The lead screw is rotatably connected to the machine frame, and the lead screw is driven to rotate by the drive assembly to increase the pushing stability.

[0016] In the above-mentioned two-winding-one-embedding integrated machine structure, each lead screw is fixed with a sprocket, and the drive component includes a servo motor and a chain. The servo motor is connected to the two sprockets through the chain for transmission, which increases the driving stability. The two-winding-one-insertion integrated machine of the present invention optimizes the structural design of the paper loading device and achieves efficient adaptation and linkage with the winding device and the inserting device. It solves the problems of low paper feeding accuracy, poor forming effect, unstable station switching and paper pushing, and insufficient slot wedge installation accuracy in the traditional integrated machine paper loading process. It realizes precise control of the entire process of slot wedge paper feeding, forming, indexing, and pushing, which greatly improves the overall processing efficiency of the integrated machine and the assembly quality of stator windings. The specific beneficial effects are as follows: 1. Precise paper feeding and excellent forming quality ensure proper slot wedge fit. The paper feeding and forming assembly uses a dual-gear friction drive to output paper sheets. Compared with traditional rollers or pneumatic paper feeding, the power transmission is more uniform, effectively avoiding paper slippage, jamming, and paper feeding length deviation, ensuring paper feeding accuracy. The gear teeth are designed in a stepped shape, which works with the paper feed channel to complete the paper sheet rolling and forming. No additional forming structure is required, and paper feeding and forming are integrated to ensure that the groove wedge cross-section shape is regular. The arc-shaped paper feed channel and the material cylinder groove wedge are precisely aligned, and there are no wrinkles or deformations in the paper sheet conveying process. After forming, the groove wedge can be accurately inserted into the warehouse and perfectly matched with the stator groove, improving the subsequent insulation and fixing effect.

[0017] 2. Flexible and efficient workstation switching enables continuous operation of the paper loading process. The frame is equipped with linear guide rails and long-distance cylinders to drive the pallet to move back and forth, enabling the material cylinder to switch quickly between paper feeding and paper pushing stations. The positioning is accurate and the movement is smooth without jamming or deviation. The material cylinder is equipped with a servo motor + synchronous belt + annular toothed indexing structure, which can realize precise circumferential indexing of the material cylinder, adjust the position of the slot wedge as needed, and adapt to the slot wedge installation requirements of multi-slot stators. The paper feeding and paper pushing processes are seamlessly connected, completely eliminating the waiting gap between stations and improving the continuous operation capability of the paper loading process.

[0018] 3. Strong paper pushing stability and precise slot wedge insertion. The paper pusher assembly adopts a dual-guided drive structure with dual guide shafts and dual lead screws. The lead screws are synchronously driven by a single servo motor through sprockets and chains, driving the sliding seat and push rod to move vertically upward smoothly. Compared with the traditional single push rod drive, it effectively avoids push rod swaying and jamming during the paper push process, and the paper push force is uniform and the stroke is precise. The push rod can completely push the slot wedge at the bottom of the material cylinder into the slot wedge magazine and accurately push it into the stator slot, without problems of incomplete pushing or tilting and offset, ensuring the slot wedge embedding accuracy and avoiding scratching the inner wall of the stator core slot.

[0019] 4. High structural integration, simplifying the overall layout of the all-in-one machine. The paper loading device integrates paper feeding and forming, paper cutting, indexing, paper pushing, and station switching components into the same frame. The components are compactly arranged and operate without interference. The paper cutting component is located near the paper feed outlet and can quickly cut continuous paper sheets after the paper is fed into place. The dimensions are accurate and do not affect subsequent paper feeding, eliminating the need for an additional paper cutting station. The paper loading device is highly compatible with the winding and embedding devices, eliminating the need for significant adjustments to the integrated machine frame layout, effectively reducing the overall footprint of the equipment and improving space utilization.

[0020] 5. Precise drive control and high degree of automation All actions of the paper loading device are precisely driven by servo motors. Servo motor one controls paper feeding and forming, servo motor two realizes the indexing of the material cylinder, and a dedicated servo motor drives the paper pushing. Each motor is linked with the integrated machine's electronic control system. The paper feeding length, forming accuracy, indexing angle, and paper pushing stroke can all be precisely adjusted through the electronic control system. The timing of paper cutting, station switching, and paper pushing actions is automatically matched. The entire process requires no manual intervention, reducing human operation errors, reducing labor costs, and improving the overall automation level of the integrated machine.

[0021] 6. Highly adaptable and versatile, meeting the processing needs of stators of various specifications. The power structure of dual-gear friction paper feeding and screw synchronous paper pushing can be adapted to paper sheets of different widths and thicknesses by adjusting the servo motor speed; the indexing angle of the feed cylinder and the paper pushing stroke can be electrically adjusted; the matching structure of the arc-shaped paper feed channel and the feed cylinder groove wedge does not require replacement of core components, and can adapt to the processing requirements of motor stator grooves and groove wedges of different numbers and specifications, greatly improving the versatility of the equipment, reducing the investment in replacement parts and the changeover time, and meeting the requirements of batch and diversified production.

[0022] 7. The equipment operates stably, has a long service life, and is easy to maintain. Each core transmission component adopts mature transmission structures such as synchronous belts, chains, and lead screws, combined with the guiding design of linear guide rails and guide shafts, resulting in low component wear and low failure rate. Key components such as material cylinders, push rods, and gears are all modular and detachable, allowing for quick disassembly and assembly during daily inspection, replacement, and maintenance, without the need to disassemble the entire paper loading device, thus reducing equipment maintenance costs and improving the overall utilization rate of the integrated machine.

[0023] 8. The efficient linkage between paper loading and wrapping processes improves the overall production efficiency of the integrated machine. The optimized paper loading device achieves high-precision and continuous slot wedge feeding, and its operation sequence is precisely matched with that of the winding device and the coil winding device. The three core processes of stator winding, slot wedge installation and coil winding are seamlessly connected, effectively shortening the overall processing cycle of the integrated machine. Compared with traditional integrated machines, it significantly improves the assembly efficiency of stator winding and meets the cycle time requirements of mass motor production.

[0026] like Figures 1-4 The embodiment shown discloses a two-winding-one-embedding integrated machine structure, the core of which lies in the optimized design of the paper loading device 3. The paper loading device 3 is integrated with the winding device 1 and the embedding device 2 of the integrated machine on the same frame 4, realizing seamless connection of the "winding-slot wedge installation-embedding" process in stator winding processing. The paper loading device 3 includes a frame 4, a paper feeding and forming assembly 5, a paper pushing assembly 6, a material cylinder 7, an indexing structure 8, and a paper cutting assembly 9. The frame 4 is clearly divided into a paper feeding station 41 and a paper pushing station 42. The material cylinder 7 can move back and forth between the two stations and achieves precise circumferential rotation through the indexing structure 8. The paper feeding and forming assembly 5 completes the guidance, driving, and forming of the paper sheet. The paper cutting assembly 9 accurately cuts the paper sheet. The paper pushing assembly 6 pushes the formed paper sheet into the slot of the material cylinder 7 and finally embeds it into the stator slot. The overall structure corresponds one-to-one with the technical features of claims 1-10.

[0027] Detailed structure and assembly of core components One rack 4 and foundation installation structure The frame 4 is welded from square steel, providing high overall rigidity and stability, and serving as a fixed mounting reference for all components. A linear guide rail 43 is arranged along the line connecting the paper feeding station 41 and the paper pushing station 42 in the central area of ​​the frame 4. The linear guide rail 43 consists of two sets of parallel high-precision linear guide rails, with a support plate 44 slidably connected to each rail. The support plate 44 is a rectangular rigid plate with a precision-machined upper surface to ensure flatness, used to support the material cylinder 7 and the indexing structure 8.

[0028] A long-distance cylinder 45 is fixed to one end of the frame 4. The cylinder body is horizontally fixed to the side of the frame 4 via an L-shaped bracket. The axis of the cylinder push rod 61 is parallel to the linear slide rail 43. The end of the push rod 61 is fixedly connected to one side of the pallet 44 via a floating joint to achieve smooth transmission of thrust and prevent jamming when the pallet 44 slides. Magnetic switches are provided at both ends of the cylinder body of the long-distance cylinder 45 to detect the position signals of the push rod 61 extending out of the paper pushing station 42 and retracting into the paper feeding station 41. The signals are fed back to the integrated machine's electronic control system for precise control, driving the pallet 44 to move the material cylinder 7 back and forth between the paper feeding station 41 and the paper pushing station 42.

[0029] Two feed cylinders 7 and indexing structure 8 The material cylinder 7 is a cylindrical hollow structure made of rigid material. Multiple sets of slot wedges are evenly spaced along its circumference, the number of which matches the number of stator slots, to accommodate the formed slot wedges. The material cylinder 7 is mounted in a bearing seat on the support plate 44 via a bearing assembly, enabling circumferential rotation. A clearance position is provided on the support plate 44 corresponding to the bottom of the material cylinder 7. This clearance position is a through-hole, allowing the push rod 61 of the paper pusher assembly 6 to pass through and act on the paper sheet at the bottom of the material cylinder 7.

[0030] The indexing structure 8 includes a second servo motor 81 and an annular toothed part 71. The annular toothed part 71 is integrally formed on the lower circumferential outer side of the material cylinder 7, and the tooth surface is hardened to improve wear resistance. The second servo motor 81 is fixed to one side of the support plate 44 through a motor mounting base. A synchronous pulley is fixed on the motor output shaft, and the transmission connection between the synchronous belt and the annular toothed part 71 of the material cylinder 7 is achieved through the synchronous belt. The synchronous belt transmission is smooth and has high precision. The second servo motor 81 is electrically connected to the integrated machine's electrical control system, which can drive the material cylinder 7 to achieve precise circumferential indexing rotation, so that each set of slot wedges in the material cylinder 7 can be precisely aligned with the discharge port of the paper feeding and forming assembly 5 and the push rod 61 of the paper pushing assembly 6 in sequence, adapting to the slot wedge installation requirements of multi-slot stators.

[0031] Three-piece paper forming assembly 5 The paper feeding and forming assembly 5 is fixed at the paper feeding station 41 of the frame 4, including the paper feed channel 51, two oppositely arranged gears 52, and a servo motor, which is responsible for guiding, driving and forming the paper sheet.

[0032] The paper feed channel 51 has an arc-shaped structure, consisting of a straight section 511 and an arc-shaped section 512. The straight section 511 is vertically positioned, with its upper end precisely aligned with the groove position on the feed cylinder 7, forming a channel for feeding paper upwards into the groove. The arc-shaped section 512 smoothly connects to the straight section 511, allowing the paper to transition smoothly from horizontal to vertical feeding, preventing wrinkles and deformation during paper transport. A notch is provided in the middle section of the paper feed channel 51, with two gears 52 correspondingly positioned at the notch, located on either side of the paper passing through. The teeth of the gears 52 are stepped, creating a rolling effect when in contact with the paper, thus working with the paper feed channel 51 to complete the paper forming process without the need for additional forming structures.

[0033] A servo motor is fixed to the side of the paper feed channel 51 via a motor bracket. The motor output shaft is connected to one of the gears 52 via a coupling or a gear set 52, providing power for the rotation of the gear 52. During operation, the servo motor drives the gear 52 to rotate. The two gears 52 form a frictional engagement with the paper sheet, and the frictional force drives the paper sheet to be conveyed along the paper feed channel 51 towards the feed cylinder 7. At the same time, the stepped tooth shape rolls and shapes the paper sheet, making the paper sheet into a cross-sectional shape that matches the stator groove.

[0034] Four-piece paper cutting assembly 9 The paper cutting assembly 9 is located near the outlet of the paper feed channel 51 and works in conjunction with the paper feeding and forming assembly 5 and the electrical control system to cut continuously fed paper sheets. The paper cutting assembly 9 adopts a cylinder-driven structure, including a paper cutting cylinder, a cutter, and a cutter holder. The cutter holder is fixed to one side of the outlet of the paper feed channel 51, the paper cutting cylinder is vertically fixed above the cutter holder, and the cutter is fixed to the lower end of the push rod 61 of the paper cutting cylinder, precisely corresponding to the blade groove on the cutter holder. When the paper feeding length reaches a preset value, the electrical control system issues a command, the push rod 61 of the paper cutting cylinder extends, driving the cutter downwards to cooperate with the cutter holder to cut the paper sheet. The cut paper sheet directly enters the groove of the feed cylinder 7. After the paper cutting action is completed, the cylinder resets, without affecting subsequent paper feeding operations.

[0035] Five-push paper assembly 6 The paper pushing assembly 6 is fixed at the paper pushing station 42 of the frame 4, and includes a push rod 61, a drive assembly 62, a sliding seat 63, a guide shaft 64 and a lead screw 66. It is used to push the formed paper sheet at the bottom of the material cylinder 7 completely into the slot, and finally push it to the stator slot.

[0036] The push rod 61 is a rigid rod-shaped structure. Its upper end is adapted to the shape of the slotted wedge, and its lower end is fixed to the center position of the upper surface of the sliding seat 63. The sliding seat 63 has guide shaft 64 holes at its opposite ends. The guide shaft 64 is vertically fixed on the frame 4. The guide shaft 64 passes through the guide shaft 64 holes and is slidably connected to the sliding seat 63 to provide guidance for the lifting and lowering of the sliding seat 63, avoid the sliding seat 63 from swaying when it moves, and improve the pushing stability.

[0037] The sliding seat 63 is provided with downwardly extending connecting parts 65 at opposite ends. The connecting parts 65 have internal threaded holes for threaded connection with the lead screw 66. The lead screw 66 is arranged vertically, with its lower end rotatably connected to the frame 4 via a bearing seat, and its upper end extending to a preset height. The lead screw 66 is arranged parallel to the guide shaft 64 to further improve the stability of the sliding seat 63's lifting and lowering. Each lead screw 66 has a sprocket 67 fixed at its lower end. The drive assembly 62 includes a servo motor and a chain 68. The servo motor is fixed on a motor mounting base at the bottom of the frame 4, and a drive sprocket 67 is fixed on the motor output shaft. The chain 68 forms a transmission connection with the sprockets 67 on the two lead screws 66, enabling a single servo motor to drive the two lead screws 66 to rotate synchronously.

[0038] During operation, the servo motor starts and drives the two lead screws 66 to rotate synchronously via the chain 68. The lead screws 66 are threadedly engaged with the connecting part 65 of the sliding seat 63, converting the rotational motion into the vertical lifting motion of the sliding seat 63. This causes the push rod 61 to move upward, pass through the clearance position of the pallet 44, and act on the paper at the bottom of the material cylinder 7, pushing the paper completely into the slot and accurately pushing it into the stator slot. After the paper is pushed, the servo motor rotates in the opposite direction, causing the push rod 61 to reset.

[0039] The paper loading device 3 and its linkage with other devices. 1. Station switching and paper feeding preparation: The electrical control system controls the long-distance cylinder 45 to retract the push rod 61, which drives the pallet 44 and the material cylinder 7 to move to the paper feeding station 41. After the magnetic switch detects the position, it sends a feedback signal; the indexing structure 8 starts, and the servo motor 81 drives the material cylinder 7 to rotate in an indexing manner, so that one set of slots is precisely aligned with the outlet of the paper feed channel 51.

[0040] 2. Paper feeding and forming: Once the servo motor of the paper feeding and forming component 5 is started, it drives the two gears 52 to rotate. After the paper sheet is guided by the arc section 512 and the straight section 511 of the paper feed channel 51, it is driven forward by the friction of the gears 52 and simultaneously the stepped tooth shape rolls and forms the paper sheet. When the paper sheet is conveyed to the preset length, the paper cutting component 9 is started, the cutter cuts the paper sheet, and the formed paper sheet falls into the groove of the material cylinder 7.

[0041] 3. Indexing and Station Switching: After one slot wedge is fed, the indexing structure 8 drives the material cylinder 7 to rotate one indexing angle, so that the next set of slot wedges is aligned with the paper feed channel 51 outlet. The paper feeding and cutting actions are repeated until all slot wedges in the material cylinder 7 are filled with slot wedges. Then the long-distance cylinder 45 push rod 61 extends, driving the material cylinder 7 to move to the paper pushing station 42.

[0042] 4. Paper Pushing and Insertion: After the material cylinder 7 moves to the paper pushing station 42, the indexing structure 8 drives the material cylinder 7 to be precisely positioned according to the position of the stator groove, so that the groove wedges in the groove library correspond one-to-one with the stator grooves; the servo motor of the paper pushing assembly 6 starts, and drives the two lead screws 66 to rotate synchronously through the chain 68, driving the sliding seat 63 and the push rod 61 to move upward, precisely pushing the groove wedges in the groove library into the stator grooves, completing the groove wedge installation.

[0043] 5. Cyclic Operation: After the paper is pushed, the push rod 61 is reset, and the long-distance cylinder 45 drives the material cylinder 7 back to the paper feeding station 41 to enter the next cycle of paper feeding, indexing, and paper pushing. At the same time, after the winding device 1 completes the stator winding, the stator moves to the slot wedge installation station, the paper loading device 3 completes the slot wedge installation, and then the stator moves to the winding device 2 to complete the winding operation, realizing the integrated continuous production of "winding-slot wedge installation-winding".
