Description

Technical Field

[0001] This invention belongs to the field of stator winding technology and relates to a two-winding-one-embedding integrated machine. Background Technology

[0002] In the motor manufacturing industry, the winding, embedding, and insulating paper forming and inlaying of stator windings are core processes that directly affect the assembly accuracy, operational stability, and service life of the motor. As motor production moves towards automation and high precision, integrated two-winding-one-embedding machines are gradually replacing traditional decentralized processing equipment, effectively improving production efficiency and reducing errors caused by manual intervention.

[0003] However, the paper forming device in the existing two-winding-one-embedding integrated machine still has many technical bottlenecks: First, the feeding, forming, cutting, and inner cylinder indexing rotation of the insulating paper rely on multiple independent drive mechanisms (such as multiple cylinders and stepper motors) for control, resulting in poor synchronization and coordination between the various actions. This easily leads to problems such as paper forming misalignment, inconsistent cutting lengths, and insufficient inner cylinder indexing accuracy, which in turn affects the compatibility of the insulating paper with the stator slot and increases the risk of failure in the subsequent winding process. Second, the setting of multiple drive mechanisms not only makes the device structure complex and occupies space. The large size of the machine increases manufacturing costs, assembly difficulty, and subsequent maintenance costs. Furthermore, the start-stop control of multiple drive sources can easily lead to energy waste. Thirdly, existing paper-pressing structures mostly use rigid transmission and lack conformal adaptation design with the inner cylinder paper slot, resulting in low contour accuracy of the insulating paper after forming, which cannot tightly adhere to the inner wall of the stator slot and affect the insulation protection effect. At the same time, the transmission reliability of the indexing structure is insufficient, and the engagement between the hook and the inner cylinder teeth is prone to slippage or jamming. The linkage response between the cutting structure and the indexing action is lagging, further reducing the overall processing efficiency.

[0004] Furthermore, traditional paper forming devices lack precise timing matching between paper cutting and inner cylinder rotation, often resulting in situations where the paper material fails to enter the designated paper slot in time after cutting, or the paper forming structure fails to operate synchronously after the inner cylinder rotates. This leads to disrupted production rhythm and difficulty in improving product qualification rate. To address these issues, there is an urgent need to develop a paper forming device with a compact structure, simple drive, high synchronization of actions, and excellent forming and cutting accuracy, to meet the automated production needs of two-winding-one-insertion integrated machines and solve the defects of existing technologies such as poor multi-drive coordination, complex structure, and insufficient processing accuracy. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a two-winding-one-embedding integrated machine. It solves the technical problem of how to develop a paper forming device with a compact structure, simple drive, high synchronization of actions, and excellent forming and cutting accuracy.

[0006] The objective of this invention can be achieved through the following technical solutions: A two-winding-one-embedding integrated machine includes a winding device, an embedding device, and a paper forming device. The paper forming device includes a material cylinder, an indexing structure, a paper-making structure, and a paper-cutting structure. The feed cylinder includes a cylinder seat and an inner cylinder rotatably connected to the inner side of the cylinder seat. The indexing structure is set at the upper end of the cylinder seat for indexing and rotating the inner cylinder. The paper-cutting structure is connected to the side of the cylinder seat for forming the paper pushed into the paper slot of the inner cylinder. The paper-cutting structure is set at the bottom of the cylinder seat for cutting off the paper supply. The paper forming device also includes a drive assembly, which includes a servo motor, a large cam and a small cam, with the large cam and the small cam being coaxially connected to the servo motor for transmission. The paper-beating structure is connected to the large cam and performs paper-beating operations through the large cam drive. The paper-cutting structure and the indexing structure are both connected to the small cam and perform paper-cutting and indexing operations through the small cam drive.

[0007] In the aforementioned two-winding-one-embedding integrated machine, the drive component includes a mounting base, on which a reducer is fixed, and the servo motor is connected to the reducer.

[0008] In the aforementioned two-winding-one-embedding integrated machine, the indexing structure includes a transmission rod, a hook, and a guide sleeve. The guide sleeve is fixed on the mounting base, and the transmission rod passes through the inner side of the guide sleeve. One end of the transmission rod is connected to a small cam. The transmission rod slides horizontally along the guide sleeve by rotating the small cam. The hook is fixed to the other end of the transmission rod. The inner cylinder has annular teeth. The hook is hooked on the annular teeth from the side and moves horizontally back and forth to hook and pull the grooves on the annular teeth in turn to drive the inner cylinder to rotate in a tiered manner.

[0009] In the above-mentioned two-winding-one-embedding integrated machine, the small cam has a cam guide groove, the transmission rod and the guide sleeve have a vertical movement allowance, the end of the transmission rod is rotatably connected to a guide wheel, the guide wheel is embedded in the cam guide groove and drives the transmission rod to slide horizontally along the guide sleeve by moving along the cam guide groove.

[0010] In the aforementioned two-winding-one-embedding integrated machine, the transmission rod has an L-shaped structure and includes an integrally formed straight section and an arc section. The straight section is slidably connected to the inner side of the guide sleeve, and the arc section extends toward the small cam, with the guide wheel connected to the end of the arc section.

[0011] In the aforementioned two-winding-one-embedding integrated machine, the hook is hinged to the transmission rod and a reset spring is fixed on the transmission rod. The end of the reset spring abuts against the hook to push the hook to engage with the annular toothed part.

[0012] In the aforementioned two-winding-one-embedding integrated machine, the paper cutting structure includes a cutting blade and a connecting rod. The connecting rod is located below the transmission rod and is slidably connected to the mounting base via a linear slide rail. The end of the connecting rod has a connecting part extending toward the arc segment. The connecting part is connected to the arc segment and can be driven by the arc segment to move horizontally. The range of horizontal reciprocating movement of the connecting part is smaller than the range of horizontal reciprocating movement of the arc segment.

[0013] In the above-mentioned two-winding-one-embedding integrated machine, a vertical groove is provided on the back side of the arc segment, and the connecting part is connected in the vertical groove through a guide wheel 2. The connecting part and the arc segment are linked by the cooperation of the guide wheel 2 and the vertical groove, and the guide wheel 2 has a margin for relative movement of the vertical groove in the vertical direction.

[0014] In the aforementioned two-winding-one-embedding integrated machine, the cutting blade is positioned against the paper groove inlet at the bottom of the inner cylinder for cutting paper.

[0015] In the aforementioned two-winding-one-embedding integrated machine, the paper-pressing structure includes a transmission block and a paper-pressing block designed to conform to the shape of the paper slot. The paper-pressing block is embedded in the inner side of the cylinder seat. One end of the transmission block is connected to the paper-pressing block, and the other end of the transmission block is provided with a guide wheel three. The guide wheel three abuts against the outer periphery of the large cam and moves along the outer periphery of the large cam to drive the transmission block to move horizontally. The beneficial effects of this invention are as follows: 1. Highly efficient collaborative drive and significantly improved motion synchronization: This invention uses a single servo motor to coaxially drive a large cam and a small cam, allowing the paper-feeding structure, paper-cutting structure, and indexing structure to share the same power source. Compared to existing multi-drive, independently controlled solutions, this completely solves the problem of misaligned action sequences. The large cam specifically drives the paper-feeding structure, while the small cam synchronously links the paper-cutting and indexing structures, achieving integrated and continuous operation of "paper feeding-indexing-paper-feeding-paper-cutting." The response time of each process is shortened, and the action connections are precise, effectively avoiding problems such as misalignment of paper forming and misalignment between paper cutting and the paper tray, significantly improving processing cycle time and product consistency.

[0016] 2. Compact and streamlined structure, reducing overall cost: The drive component adopts an integrated design of "servo motor + reducer + dual cams," eliminating the multiple cylinders, stepper motors, and complex electronic control synchronization modules found in traditional solutions. This simplifies the overall structural layout and reduces the space occupied by the equipment. Simultaneously, the number of parts is significantly reduced, lowering manufacturing costs and assembly difficulty, as well as reducing subsequent maintenance workload and parts replacement costs. Compared to multiple drive sources, single servo motor drive significantly reduces energy consumption, further improving the equipment's economic efficiency.

[0017] 3. Reliable linkage between indexing and paper cutting, optimized operational accuracy: The indexing structure, through the cooperation of an L-shaped transmission rod, a guide sleeve, and the cam guide groove of a small cam, combined with the rolling guidance of a guide wheel, achieves smooth horizontal sliding of the transmission rod. Under the action of the reset spring, the hook always reliably engages with the annular teeth of the inner cylinder, avoiding slippage or jamming, and ensuring the accuracy and stability of the inner cylinder's indexing rotation. The paper cutting structure, through the cooperation of a connecting rod, a guide wheel, and the vertical groove of the arc section of the transmission rod, achieves synchronous linkage with the indexing action. At the same time, through vertical movement allowance compensation, it avoids action interference. The cutting blade is set close to the paper groove inlet of the inner cylinder, and the paper cutting length is precisely controllable, effectively ensuring the consistency of paper material size.

[0018] 4. Excellent paper forming quality and stronger adaptability: The paper forming structure adopts a paper pressing block designed to conform to the inner cylinder paper groove, which can make the insulating paper completely fit the outline of the paper groove after forming, improving the adaptability of the insulating paper and the stator slot, and enhancing the insulation protection effect of the motor; the paper pressing block is driven by the transmission block and the guide wheel on the outer periphery of the large cam, which makes the transmission smooth and the pressure uniform, avoiding problems such as wrinkles and damage during the paper forming process, and further improving the product processing quality.

[0019] 5. Stable overall operation and convenient maintenance: Each transmission structure adopts the rolling cooperation of guide wheels, cam guide grooves, and vertical grooves. Compared with rigid sliding transmission, it has less wear, lower operating noise, and extended service life of the equipment. The connection between the drive components and each functional structure is simple, which facilitates later maintenance and component replacement, reduces equipment downtime for maintenance, and ensures continuous and stable operation of the production line.

[0022] The following describes in detail the specific implementation of the two-winding-one-embedding integrated machine and the paper forming device 3 in conjunction with the overall structure of the present invention. This embodiment is only used to explain the present invention and is not intended to limit the scope of protection of the present invention.

[0023] like Figs. 1-3 The invention shown is a two-winding-one-embedding integrated machine that integrates three core functional modules: a winding device 1, an embedding device 2, and a paper forming device 3. The three devices are connected and arranged on the frame of the integrated machine, realizing the integrated continuous operation of insulating paper forming, winding, and stator embedding in the processing of motor stator windings. The action sequence of each device is coordinated through the main control system of the integrated machine to ensure the continuity and accuracy of the processing flow.

[0024] I. Structure of Winding Device 1 The winding device 1 is installed at the feed end of the frame, adjacent to the discharge side of the paper forming device 3. It includes a winding spindle, a wire spool support, a tension adjustment component, a wire laying mechanism, and a winding positioning fixture. The winding spindle is horizontally connected to the frame and driven by a dedicated servo drive to achieve speed regulation. The winding positioning fixture is coaxially fixed to the end of the winding spindle and is used to clamp the winding bobbin and achieve the positioning and winding of the winding. The wire spool bracket is set on the side of the frame and is used to place the enameled wire spool. After the enameled wire is led out from the spool, it passes through the tension adjustment component and the wire laying mechanism in sequence, and finally enters the winding bobbin on the winding positioning fixture. The tension adjustment component adjusts the tension of the enameled wire in real time through the cooperation of the tension wheel and the elastic pressure plate to prevent the enameled wire from loosening or breaking during the winding process. The wire laying mechanism is a screw-slider structure that is linked with the winding spindle and drives the enameled wire to be laid evenly along the axial direction of the winding bobbin to achieve regular winding of the winding. After the winding is completed, the winding is pushed by the pusher of the winding device 1 to the loading station of the winding device 2 to complete the connection between the winding process and the winding process.

[0025] II. Structure of the Wire-Wrapping Device 2 The winding device 2 is positioned at the midpoint between the winding device 1 and the paper forming device 3. Its feed end connects to the discharge end of the winding device 1, and its discharge end corresponds to the stator processing unloading station. The winding device 2 includes a stator positioning fixture, a winding pusher, a slot expansion assembly, and a feeding guide rail. The stator positioning fixture is fixed to the frame and is used to precisely clamp the motor stator core, ensuring accurate alignment between the stator core slot and the winding pusher and the paper slot outlet of the paper forming device 3. The winding pusher is driven by a linear drive component to perform horizontal reciprocating linear motion. Its pusher end is designed to conform to the slot of the stator core, pushing the winding completed by the winding device 1 into the slot of the stator core. The slot expansion assembly is located on both sides of the stator positioning fixture and consists of expansion blocks driven by pneumatic components. Before operation, the expansion block extends into the slot of the stator core and expands outward to increase the operating space of the slot and prevent the winding or stator core from being scratched during the winding process. The feeding guide rail is inclined between the winding device 1 and the winding pusher to receive the winding pushed by the winding device 1 and guide the winding so that the winding accurately enters the pushing position of the winding pusher. After the winding is completed, the slot expansion component is reset, the stator positioning fixture is released, and the stator with the winding completed is pushed to the next processing step by the unloading mechanism.

[0026] III. Detailed Structure and Assembly of Paper Forming Device 3 The paper forming device 3 is installed on the side of the frame near the winding device 2. Its discharge port is precisely aligned with the wire groove inlet of the stator positioning fixture. It is used to process the insulating paper into a shape that matches the stator wire groove and then accurately feed it into the wire groove of the stator core, preparing for the subsequent winding process with insulation protection. The paper forming device 3 includes a material cylinder 4, an indexing structure 5, a paper forming structure 6, a paper cutting structure 7, and a drive assembly 8. All components are assembled on the mounting base of the device, which is fixed to the integrated machine frame to ensure the stability of the device operation. The assembly and connection relationship of the core structures of the paper forming device 3 are described below: 1. Assembly of the material cylinder 4: The material cylinder 4 consists of a cylinder base 41 and an inner cylinder 42. The cylinder base 41 is a cylindrical frame structure, fixed on the mounting base. The inner cylinder 42 is coaxially arranged inside the cylinder base 41, and the inner cylinder 42 and the cylinder base 41 are rotated together by a rotating connector, so that the inner cylinder 42 can rotate circumferentially relative to the cylinder base 41. Several paper grooves are opened circumferentially on the inner side of the inner cylinder 42. The groove shape is designed to resemble the groove of the stator core, which is used to receive the insulating paper to be formed and to provide forming positioning for the insulating paper. The lower outer circumference of the inner cylinder 42 is provided with annular teeth 421, which provides a base for the transmission of the indexing structure 5. The insulating paper is fed in from the side feed port of the cylinder base 41 and guided into the paper groove of the inner cylinder 42 through the guide structure, in preparation for subsequent paper forming.

[0027] 2. Drive Component 8 Assembly: The drive component 8 is the power core of the paper forming device 3, including a mounting base 84, a servo motor 81, a reducer, a large cam 82, and a small cam 83. The mounting base 84 is fixed on the mounting base of the paper forming device 3, and the reducer is fixed on the mounting base 84. The output end of the servo motor 81 is connected to the input end of the reducer to achieve power reduction and torque increase. The large cam 82 and the small cam 83 are coaxially fixed on the output shaft of the reducer. They rotate synchronously with the output shaft of the reducer. The contours of the large cam 82 and the small cam 83 are designed according to the action sequence of paper forming, paper cutting, and indexing to ensure precise action connection of each structure. The large cam 82 provides transmission power for the paper forming structure 6, and the small cam 83 provides transmission power for the paper cutting structure 7 and the indexing structure 5 at the same time, realizing the linkage operation of multiple structures driven by a single power source.

[0028] 3. Indexing Structure 5 Assembly: The indexing structure 5 is located at the upper end of the cylinder seat 41 and is used to drive the inner cylinder 42 to perform precise circumferential indexing rotation, so that the paper groove of the inner cylinder 42 is aligned with the feed port, the paper-breaking structure 6, and the discharge port in sequence. It includes a transmission rod 51, a hook 52, a guide sleeve 53, and a guide wheel 1. The guide sleeve 53 is fixed on the mounting base 84, and its axis is parallel to the radial direction of the inner cylinder 42. The transmission rod 51 is an L-shaped integral structure, including a straight section 511 and an arc section 512. The straight section 511 slides through the inner side of the guide sleeve 53, and a vertical movement margin is reserved between the transmission rod 51 and the guide sleeve 53 to avoid structural interference during transmission. The arc section 512 extends towards the small cam 83, and its end is rotatably connected to the guide wheel 1 through a pin. The small cam 83 has a cam guide groove 1 831, and the guide wheel 1 is adapted to be embedded in the small cam 83. When the small cam 83 rotates within the cam guide groove 831, it drives the guide wheel to move through the guiding action of the cam guide groove 831, thereby driving the transmission rod 51 to slide horizontally back and forth along the guide sleeve 53. The hook 52 is hinged to the end of the straight section 511 of the transmission rod 51 away from the arc section 512. The annular toothed part 421 of the inner cylinder 42 is adapted to the hook head of the hook 52. A reset spring 54 is also fixed on the transmission rod 51. The end of the reset spring 54 elastically abuts against the non-hooked end of the hook 52, providing a continuous elastic force to the hook 52, so that the hook 52 always maintains the hooking tendency toward the annular toothed part 421. This ensures that when the transmission rod 51 moves horizontally, the hook 52 can be stably hooked in the tooth groove of the annular toothed part 421. Through the horizontal reciprocating movement of the hook 52, the tooth groove of the annular toothed part 421 is pulled in sequence, driving the inner cylinder 42 to make precise circumferential indexing rotation.

[0029] 4. Paper-pressing structure 6 assembly: The paper-pressing structure 6 is connected to the side of the cylinder base 41, and the paper-pressing end is horizontally aligned with the paper groove of the inner cylinder 42. It is used to compress the insulating paper fed into the paper groove and make it fit the shape of the paper groove. It includes a transmission block 61, a paper-pressing block 62 and a guide wheel three. The paper-pressing block 62 is designed to conform to the shape of the paper groove of the inner cylinder 42. It is embedded in the inner side of the cylinder base 41 and is opposite to the opening end of the paper groove. The end of the paper-pressing block 62 can extend into the paper groove to realize the compression and forming of the insulating paper. One end of the transmission block 61 is fixedly connected to the paper-pressing block 62, and the other end extends toward the large cam 82. The end is rotatably connected to the guide wheel three. The guide wheel three directly abuts against the outer peripheral surface of the large cam 82. When the large cam 82 rotates, the change of the outer peripheral contour drives the guide wheel three to move horizontally back and forth, thereby driving the transmission block 61 to drive the paper-pressing block 62 to move horizontally linearly closer to or away from the paper groove to complete the paper-pressing and forming operation.

[0030] 5. Paper Cutting Structure 7 Assembly: The paper cutting structure 7 is located at the bottom of the cylinder base 41, with its cutting end abutting against the feeding end of the paper groove in the inner cylinder 42. It is used to precisely cut the continuously fed insulating paper according to processing requirements. It includes a cutting blade 71, a connecting rod 72, a linear slide rail, a connecting part 73, and a guide wheel 2. The linear slide rail is fixed on the mounting base 84 and parallel to the sliding direction of the transmission rod 51. The connecting rod 72 is slidably connected to the linear slide rail via a slider to ensure the smoothness and straightness of the sliding of the connecting rod 72. The cutting blade 71 is fixed at the end of the connecting rod 72 near the cylinder base 41, and its blade is precisely aligned with the paper groove inlet at the bottom of the inner cylinder 42 to ensure that the length of the cut insulating paper is appropriate for the paper groove. The connecting rod 72 has a connecting part 73 extending toward the arc segment 512 of the transmission rod 51 at the other end. The arc segment 512 of the transmission rod 51 has a vertical groove on its back side. The connecting part 73 is fitted into the vertical groove through a guide wheel 2. The guide wheel 2 can move vertically in the vertical groove and form a linkage with the vertical groove in the horizontal direction. When the transmission rod 51 moves horizontally, it can drive the connecting part 73 and the connecting rod 72 to move horizontally synchronously through the cooperation of the vertical groove and the guide wheel 2. At the same time, the range of horizontal reciprocating movement of the connecting part 73 is smaller than the range of horizontal reciprocating movement of the arc segment 512, realizing the linkage between the paper cutting action and the indexing action and matching the action stroke, avoiding interference between the two.

[0031] IV. Working Principle of Paper Forming Device 3 All actions of the paper forming device 3 are synchronously driven by a single servo motor 81 through the large cam 82 and the small cam 83. After the servo motor 81 starts, it drives the reducer to run, which in turn drives the large cam 82 and the small cam 83 to rotate synchronously on the same axis. 1. Paper-making action: The large cam 82 rotates, and through the cooperation of the outer contour and the guide wheel three, it drives the transmission block 61 to make horizontal reciprocating linear motion. The transmission block 61 drives the paper pressing block 62 to reciprocate into the paper groove of the inner cylinder 42, and squeezes the insulating paper fed into the paper groove into a shape that matches the paper groove and the stator wire groove, thus completing the paper-making and forming of the insulating paper. 2. Indexing action: The small cam 83 rotates, and through the guiding cooperation of the cam guide groove 831 and the guide wheel 831, it drives the L-shaped transmission rod 51 to slide horizontally back and forth along the guide sleeve 53. The hook 52 at the end of the transmission rod 51 is stably hooked on the annular tooth 421 of the inner cylinder 42 under the action of the reset spring 54. The horizontal movement of the hook 52 pulls the annular tooth 421, driving the inner cylinder 42 to make precise circumferential indexing rotation, so that the paper trough of the inner cylinder 42 completes the work position switching of feeding, paper cutting and discharging in sequence. 3. Paper cutting action: When the transmission rod 51 slides horizontally, the vertical groove of its arc section 512 drives the connecting part 73 and the connecting rod 72 to move horizontally synchronously along the linear slide rail through the second guide wheel. The connecting rod 72 drives the cutting knife 71 to approach or move away from the paper tray inlet. When the inner cylinder 42 completes indexing and the insulation paper is formed in place, the cutting knife 71 accurately cuts the insulation paper to prepare for the feeding of the next paper tray. The paper cutting structure 7 and the indexing structure 5 share the power source of the small cam 83, realizing the synchronous linkage of the paper cutting action and the indexing action. The paper punching structure 6 is driven independently by the large cam 82, and the timing of the paper cutting and indexing actions is precisely matched with the cam profile. Finally, the integrated continuous operation of insulation paper feeding, indexing, paper punching and paper cutting is realized. The formed insulation paper is pushed from the discharge end of the inner cylinder 42 to the stator positioning fixture of the winding device 2, and precisely aligned with the wire groove of the stator iron core, providing insulation protection for the subsequent winding process.

[0032] V. Overall Workflow of the Two-Wrap-One-Inlay Integrated Machine After the integrated machine is started, the main control system first links the paper forming device 3 to start operation, which processes the insulating paper into the wire slot of the stator core and sends it into the slot to complete the insulation protection of the stator wire slot. Then the winding device 1 starts and completes the winding of the motor winding according to the preset parameters. After the winding is completed, the winding is pushed by the feeding guide to the winding push head position of the winding device 2. The slot expansion component of the winding device 2 first expands the wire slot of the stator core. The winding push head accurately pushes the wound winding into the stator wire slot that has been covered with insulating paper to complete the winding operation. After the winding is completed, the slot expansion component is reset, the stator positioning fixture is released, and the finished stator is pushed to the next process by the unloading mechanism. At the same time, the paper forming device 3 and the winding device 1 start the next processing cycle in sync, realizing the integrated continuous processing of insulating paper forming, winding, and stator winding.
