Description

Technical Field

[0001] The present invention relates to the technical field of coil manufacturing equipment, and in particular to a rotary winding device and a winding method. Background Art

[0002] Hollow cup coils are a commonly used accessory in industrial equipment. Hollow cup coils are generally widely used in micro drive motors in equipment. They are widely used due to their small specifications, high output speed, low moment of inertia, no cogging, and low friction.

[0003] In the existing technology, the production process of hollow cup coils requires first completing the coil winding on the mold, and then installing the wound coil on the stator of the motor. However, the existing fully automated winding equipment still has the following shortcomings in the coil winding process: During the continuous winding process, the connecting wires between each set of coils are long, which cannot meet the requirements of the fully automated winding process for small hollow cup motor coils, resulting in poor coil density and increased material waste. Summary of the Invention

[0004] In view of this, in order to solve the defects of the above-mentioned technology, the present invention provides a rotary winding device and a winding method.

[0005] The first object of the present invention is to provide a rotary winding device for winding a copper wire guided out of a threading core shaft component to obtain a hollow cup motor coil, comprising: Support seat; A driving assembly is provided on one side of the support seat; A winding component, comprising a triangular support base vertically connected to one side of the top of the support base and a winding structure rotatably mounted on the triangular support base; a wire guide component mounted on the wire winding component; A pinch wheel component is installed on one side of the winding component, and the pinch wheel component is suitable for pressing the copper wire on the working surface of the winding component.

[0006] Optionally, the support seat includes a connecting plate horizontally located on the base and a vertical bottom plate fixedly connected to the connecting plate.

[0007] Optionally, the driving assembly includes: A servo motor is vertically mounted on one side of the triangular support base; A gear transmission structure is installed on the other side of the triangular support seat, and one side of the gear transmission structure is drive-connected to the servo motor, and the other side of the gear transmission structure is drive-connected to the winding structure.

[0008] Optionally, the servo motor is fixedly connected to one side of the triangular support base through a motor mounting base.

[0009] Optionally, the gear transmission structure includes a first indexing gear mounted on the output shaft of the servo motor, an intermediate gear rotatably mounted on the triangular support seat, and a transmission sun gear rotatably mounted on the triangular support seat, one side of the intermediate gear is engaged with the first indexing gear for transmission, and the other side is engaged with the transmission sun gear for transmission.

[0010] Optionally, the winding structure includes a rotating shaft vertically mounted on the triangular support seat and a winding tooling passed through the rotating shaft, the winding tooling having four sides, each side having a plurality of winding grooves arranged horizontally, parallel, and spaced apart and interconnected.

[0011] Optionally, the wire guide component includes a mounting post vertically installed in the triangular support seat and a guide wire connected between the winding tool and the mounting post.

[0012] Optionally, the pressure wheel component includes a pressure mounting plate connected to the triangular support seat, a pressure wheel guide seat vertically connected to the pressure mounting plate, two guide rods horizontally connected to both sides of the pressure wheel guide seat, a rotating shaft vertically rotatably installed between the two guide rods, a pressure wheel installed on the rotating shaft, and an elastic member sleeved on the guide rod, and the pressure wheel is suitable for pressing against the side of the winding tooling.

[0013] Optionally, it also includes a conveyor belt component horizontally arranged below the guide wire and the pressure wheel.

[0014] A second object of the present invention is to provide a winding method for a rotary winding device, the winding method comprising the steps of: Step S 100 : Complete the copper wire winding forming on the winding mandrel; Step S 200 : The driving component controls the rotary winding tooling to rotate 90 degrees to change the working surface. The coil on the original working surface of the winding tooling is first pressed onto the original working surface by the pressing wheel on the pressing wheel assembly; Step S 300 : When it rotates 90 degrees again, the coil that has passed the pinch wheel is peeled off by the guide wire and falls onto the conveyor belt component for discharge.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: 1. The rotary winding device of the present invention includes a support seat, a drive assembly, a winding part, a wire guide part and a pressure wheel part. The winding part is the core part for directly winding the copper wire. The winding part includes a triangular support seat and a winding structure. The triangular support seat is vertically connected to the top side of the support seat. The winding structure is rotatably installed on the triangular support seat. The triangular structure of the triangular support seat provides good stability and load-bearing capacity. The rotatable installation of the winding structure is used to improve the flexibility and adaptability of winding. The pressure wheel part presses the copper wire on the working surface of the winding part, so that the copper wire on the working surface of the winding part can be pressed, ensuring the tightness and stability of the copper wire during the winding process. After the copper wire is wound on the winding core shaft, the drive assembly controls the rotary winding tool to rotate 90 degrees to change the working surface. The coil on the original working surface of the winding tool is first pressed onto the original working surface by the pressure wheel on the pressure wheel assembly. When it rotates 90 degrees again, the coil that has passed the pressure wheel is peeled off by the guide wire and falls onto the conveyor line for discharge. Since the winding tooling (tetrahedral structure) winds the coil outlet on one side to the wire inlet on the next side, a straight line distance is selected in space so that the connecting line between two adjacent groups of coils is shorter, meeting the requirements of multiple groups of continuous micro hollow cup motor coils and the intermediate connecting line cannot be too long.

[0016] 2. The coreless motor coil is finally formed by winding the copper wire guided out of the threading core shaft component. The entire device realizes the automation of the winding process through the coordinated work of the drive component, winding component, wire guide component and pressure wheel component, thereby improving production efficiency and reducing manual intervention.

[0017] 3. By combining a rotary winding device with a flying fork winding method, the coil can be wound continuously, solving the technical problem of existing coreless motors that require continuous winding of multiple coils. Compared with the existing manual winding method, this method not only ensures coil quality and consistency, but also significantly improves efficiency. In addition, the structural design of the rotary winding assembly shortens the connecting wire between adjacent coils, meeting the requirements of micro-coreless motors that multiple coils must be continuous and the connecting wire must not be too long.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention. In the description of the present invention, it should be noted that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components; wireless connections or wired connections. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0021] Figure 1-5 The figure shows a rotary winding device provided by an embodiment of the present invention, which is used to wind a copper wire 8 guided out of the outside of a threading core shaft component 7 to obtain a hollow cup motor coil. The rotary winding device includes a support base 1, a drive assembly 2, a winding component 3, a wire guide component 4 and a pressure wheel component 5, wherein: The support base 1 serves as the foundation of the entire device and provides a stable installation platform for other components to ensure the stability and load-bearing capacity of the entire device during operation.

[0022] The driving assembly 2 is arranged on one side of the support base 1, and while optimizing space utilization, it is also necessary to ensure the efficiency and stability of power transmission.

[0023] The winding component 3 includes a triangular support seat 31 and a winding structure 32. The triangular support seat 31 is vertically connected to the top side of the support seat 1, and the winding structure 32 is rotatably installed on the triangular support seat 31. The triangular structure of the triangular support seat 31 provides good stability and load-bearing capacity, and the rotatable installation of the winding structure 32 is used to improve the flexibility and adaptability of winding.

[0024] The support base 1 provides a stable mounting base for the triangular support base 31. Its structural design needs to consider strength, rigidity, and adjustability. The triangular structure of the triangular support base 31 can provide multiple winding positions, improving the flexibility and efficiency of winding. The rotational movement of the winding structure 32 is used to achieve the winding of the copper wire 8. By precisely controlling its rotation speed and angle, the winding quality and dimensional accuracy of the coil can be guaranteed. At the same time, the winding structure 32 should also be considered to facilitate the removal and replacement of the coil to improve production efficiency.

[0025] The wire guide component 4 is installed on the winding component 3 to accurately guide the copper wire 8 to the winding area, thereby reducing the deviation and entanglement problems of the copper wire during the winding process.

[0026] The pressure wheel component 5 is installed on one side of the winding component 3. The pressure wheel component 5 is suitable for pressing the copper wire 8 on the working surface of the winding component 3. In this way, the copper wire 8 on the working surface of the winding component 3 can be pressed, ensuring the tightness and stability of the copper wire 8 during the winding process.

[0027] It can be understood that the winding component 3 is the core component that directly performs the winding operation on the copper wire 8. It winds the copper wire 8 guided out of the outside of the threading core shaft component 7 to eventually form a hollow cup motor coil. The entire device realizes the automation of the winding process through the coordinated work of the driving component 2, the winding component 3, the wire guiding component 4 and the pressure wheel component 5, thereby improving production efficiency and reducing manual intervention.

[0028] It is important to note that the rotary winding device must be equipped with high-precision winding capabilities, capable of automatically winding according to preset parameters (such as the number of turns and winding tension). The control accuracy of winding speed and winding tension directly affects the quality and performance of coreless motor coils. This rotary winding device, through the coordinated operation of various components, achieves fully automated winding of coreless motor coils. Its design significantly improves winding accuracy, efficiency, and flexibility, meeting the demand for high-quality and efficient production of coreless motor coils.

[0029] Specifically, see Figure 1 As shown, the support base 1 includes a connecting plate 11 and a vertical bottom plate 12 . The connecting plate 11 is horizontally located on the base, and the vertical bottom plate 12 is fixedly connected to the connecting plate 11 .

[0030] As a preferred embodiment of this invention, the combined design of the connecting plate 11 and the vertical bottom plate 12 provides stable support for the entire device, wherein the horizontal placement of the connecting plate 11 can disperse the weight of the device, while the vertical bottom plate 12 provides vertical support for other components.

[0031] Specifically, see Figure 1 、 2 As shown, the drive assembly 2 includes a servo motor 21 and a gear transmission structure 22, wherein: The servo motor 21 is vertically mounted on one side of the triangular support 31, and the gear transmission structure 22 is mounted on the other side of the triangular support 31. One side of the gear transmission structure 22 is drivingly connected to the servo motor 21, and the other side of the gear transmission structure 22 is drivingly connected to the winding structure 32. This arrangement not only optimizes space utilization but also ensures efficient power transmission.

[0032] In addition, the present embodiment adopts a gear transmission structure 22 because gear transmission has higher torque transmission capability and lower energy loss compared with other transmission modes (such as chain transmission or belt transmission).

[0033] Specifically, see Figure 1 As shown, the servo motor 21 is fixedly connected to one side of the triangular support base 31 through a motor mounting base 211 .

[0034] In this embodiment, the motor mounting base 211 fixes the servo motor 21 to one side of the triangular support base 31, providing a stable mounting platform for the servo motor 21. In addition, the rigid structure of the motor mounting base 211 can reduce the vibration and shaking of the servo motor 21 during operation, ensuring the stability of power transmission.

[0035] See also Figure 1 、 2 As shown, the gear transmission structure 22 includes a first indexing gear 221, an intermediate gear 222 and a transmission sun gear 223, wherein: The first indexing gear 221 is mounted on the output shaft of the servo motor 21, the intermediate gear 222 is rotatably mounted on the triangular support base 31, and the transmission sun gear 223 is rotatably mounted on the triangular support base 31. One side of the intermediate gear 222 meshes with the first indexing gear 221, and the other side meshes with the transmission sun gear 223. In this way, the gear transmission structure 22 can efficiently transmit the power of the servo motor 21 to the winding component 3 through the meshing transmission of the first indexing gear 221, the intermediate gear 222, and the transmission sun gear 223.

[0036] In this embodiment, the gear transmission structure 22 is used to achieve efficient power transmission and precise speed control. Through the meshing transmission between the gears, the power of the servo motor 21 is accurately transmitted to the winding structure 32, achieving its rotational motion. The transmission sun gear 223 is mounted at the bottom end of the triangular support 31 and connected to the intermediate gear 222, achieving power transmission. This transmission connection method ensures stable and reliable transmission, ensuring the normal operation of the winding structure 32.

[0037] It is important to note that gear transmission has the advantages of high transmission precision and strong torque carrying capacity, which can ensure the stability and reliability of the winding process. At the same time, by properly designing the gear ratio, different winding speeds and torque outputs can be achieved to meet the requirements of different winding processes.

[0038] Through the high-precision control characteristics of the servo motor 21, the power is accurately transmitted through the gear transmission structure 22. The gear transmission can ensure accurate control of the rotation speed and angle, thereby achieving high-precision winding operations.

[0039] See also Figure 1 、 3As shown, the winding structure 32 includes a rotating shaft 321 and a winding tool 322. The rotating shaft 321 is vertically rotatably installed on the triangular support seat 31, providing stable rotational support for the winding tool 322; the winding tool 322 is passed through the rotating shaft 321, and the winding tool 322 has four sides, each of which is provided with a number of horizontally parallel winding grooves 3221 arranged at intervals and interconnected. This multi-sided design allows multi-sided winding to be performed simultaneously, significantly improving the winding efficiency.

[0040] It can be understood that the horizontal parallel spacing of the winding grooves 3221 can ensure the uniform distribution and tight arrangement of the copper wires during the winding process, avoid crossing and entanglement of the copper wires, and improve the forming quality of the coil.

[0041] Specifically, see Figure 1 、 2 As shown, the wire guide component 4 includes a mounting column 41 and a guide wire 42. The mounting column 41 is vertically installed in the triangular support seat 31 to provide stable support for the guide wire 42. The guide wire 42 is connected between the winding tooling 322 and the mounting column 41 to ensure the stability of the guide wire 42 when guiding the copper wire, thereby reducing the deviation or shaking of the copper wire during the guiding process.

[0042] Specifically in this embodiment, the guide wire 42 is connected between the winding tool 322 and the mounting post 41, which can accurately guide the copper wire to the winding area, reducing the deviation and entanglement problems of the copper wire during the winding process.

[0043] Thus, through the guiding effect of the guide wire 42, the copper wire 8 can reach the winding position along a predetermined path, avoiding deviation or entanglement during the winding process, thereby improving the neatness and quality of the winding.

[0044] The combination of mounting post 41 and guide wire 42 applies a certain amount of tension to copper wire 8, ensuring that copper wire 8 remains appropriately taut during the winding process. This tension control helps improve the tightness and consistency of the coil, and avoids winding quality issues caused by loose copper wire 8.

[0045] It is understood that the design of the wire guide component 4 must ensure an accurate and stable path for the copper wire 8 as it enters the winding tool 322. Its guiding function prevents the copper wire 8 from drifting and tangling during the winding process, thereby improving the neatness and quality of the winding. Furthermore, the wire guide component 4 should also have a certain degree of adjustability to accommodate copper wires 8 of varying specifications and winding requirements.

[0046] Thus, the wire guide component 4 is responsible for accurately guiding the copper wire 8 onto the winding tooling 322, while the pressure wheel component 5 ensures that the copper wire 8 fits tightly against the winding tooling during the winding process. This combination of guidance and pressure can effectively improve the neatness and quality of the winding, and avoid problems such as deviation, looseness, or gaps in the copper wire 8 during the winding process. The elastic adjustment function of the pressure wheel component 5 and the tension control function of the wire guide component 4 enable the entire device to be dynamically adjusted according to the tension of the copper wire 8 and the shape of the winding tooling. This dynamic adjustment capability enhances the adaptability and flexibility of the device and can meet the production requirements of hollow cup motor coils of different specifications and models.

[0047] The wire guide component 4 and the pressure wheel component 5 together constitute an important part of the winding component 3 , and work together with other components such as the winding component 3 to achieve precise winding of the copper wire 8 .

[0048] See also Figure 1 、 2 As shown, the pressure wheel component 5 includes a pressure mounting plate 51, a pressure wheel guide seat 52, two guide rods 53, a rotating shaft 54, a pressure wheel 55 and an elastic member 56, wherein: The pinch wheel mounting plate 51 is connected to the triangular support base 31, and the pinch wheel guide 52 is vertically connected to the pinch wheel mounting plate 51, providing a stable mounting base for the pinch wheel assembly. A guide rod 53 is horizontally connected to ensure the horizontal movement stability of the pinch wheel 55. Two guide rods 53 are horizontally connected to either side of the pinch wheel guide 52. A rotating shaft 54 is vertically rotatably mounted between the two guide rods 53. The pinch wheel 55 is mounted on the rotating shaft 54, and an elastic member 56 is sleeved on the guide rod 53. The pinch wheel 55 is suitable for pressing against the side of the winding tool 322.

[0049] Specifically in this embodiment, the pressure wheel 55 is pressed against the side of the winding tooling 322 by the elastic force of the elastic member 56. It can automatically adjust the pressure according to the tension of the copper wire, ensuring that the copper wire maintains appropriate tension during the winding process and avoids loosening or over-tightening. The pressure wheel 55 is also used to apply uniform pressure to the copper wire 8, ensuring that the copper wire 8 is closely attached to the surface of the winding structure 32 during the winding process. This compression effect helps to improve the tightness and consistency of the coil, prevent the copper wire 8 from loosening or gapping during the winding process, and thus improve the winding quality.

[0050] The use of the elastic member 56 allows the pressing wheel 55 to freely adjust the pressing force within a certain range, and can also compensate for changes in the tension of the copper wire, ensuring that the pressing wheel 55 always presses the copper wire with appropriate force.

[0051] Therefore, through the combined design of the clamping mounting plate 51, the clamping wheel guide seat 52, the guide rod 53, the rotating shaft 54, the clamping wheel 55 and the elastic member 56, efficient and stable copper wire clamping is achieved, while having the advantages of stable structure, good clamping effect and convenient maintenance.

[0052] The setting of the elastic member 56 provides an elastic support force for the pinch wheel 55, so that it can be properly adjusted according to the tension of the copper wire 8 and the shape of the winding tooling. This elastic adjustment function can adapt to copper wires 8 of different specifications and diameters, enhancing the versatility and adaptability of the device.

[0053] An embodiment of the present invention further provides a winding method for a rotary winding device, the winding method comprising the steps of: Step S 100 : Complete the copper wire winding forming on the winding mandrel; Step S 200 : The driving assembly 2 controls the rotary winding tooling 322 to rotate 90° to change the working surface. The coil on the original working surface of the winding tooling 322 is first pressed onto the original working surface by the pressing wheel 55 on the pressing wheel assembly 5; Step S 300 : When it rotates 90 degrees again, the coil that has passed the pinch wheel 55 is peeled off by the guide wire and falls onto the conveyor line for discharge.

[0054] Specifically in the embodiment of the present invention, the driving cylinder of the threading core shaft component 7 contracts, and the threading tube of the threading core shaft component 7 is pushed to slide in the rotating main shaft by moving the baffle, so that the winding core shaft tooling extends to the outside of the die head, and the sliding platform moves to control the distance between the end face of the winding core shaft tooling and the tooling surface of the winding tooling 322 of the rotating winding device.

[0055] The servo motor controlling the die head drive assembly 10 remains stationary, and the driving structure 92 of the flying fork motion assembly 9 works to drive the first flying fork 94 to rotate, winding the copper wire 8 on the copper wire guide assembly 20 onto the winding mandrel tooling, and forming it between the end face of the winding mandrel tooling and the tooling surface of the winding tooling 322.

[0056] The rotation and swing of the flying fork motion assembly 9 are used to control the rhythm and trajectory of the copper wire winding. The flying fork motion assembly 9 in this embodiment includes a rotating seat 91, a driving structure 92, a rotating main shaft 93 and a first flying fork 94. The rotating seat 91 is installed on the sliding platform, and the driving structure 92 is installed on the rotating seat 91 to provide power for the rotation of the rotating main shaft 93; the rotating main shaft 93 is rotatably installed on the rotating seat 91, so that the rotating main shaft 93 can rotate flexibly on the rotating seat 91; the first flying fork 94 is sleeved on the side of the rotating main shaft 93 away from the rotating seat 91, and the driving structure 92 is suitable for driving the rotating main shaft 93 to rotate, and drive the first flying fork 94 to rotate together, thereby realizing the winding action of the copper wire.

[0057] For being able to realize the stable rotation of die head 103, and can adjust rotational speed and angle as required, die head drive assembly 10 in the present embodiment comprises sprocket drive component 101, transition sprocket component 102 and die head 103, servo motor among the sprocket drive component 101 is installed in a side of rotating base 91, die head 103 rotation is sleeved on rotating main shaft 93 away from one end of threading mandrel component 7, one end of transition sprocket component 102 is drive-connected with sprocket drive component 101, and the other end of transition sprocket component 102 is drive-connected with die head 103.Coordinated like this by the rotation of die head 103 and the rotation of flying fork motion assembly 9, form a complete winding mode, improve the precision and efficiency of winding.Simultaneously, the mode of sprocket drive can guarantee the stability and reliability of power transmission.

[0058] The copper wire guide assembly 20 includes a first guide assembly 201, a second guide assembly 202, and a third guide assembly 203. The copper wire 8 is threaded into the threading core shaft component 7 and is adapted to be guided out of the threading core shaft component 7 by the first guide assembly 201, the second guide assembly 202, and the third guide assembly 203. Through the joint guidance of the first guide assembly 201, the second guide assembly 202, and the third guide assembly 203, the copper wire 8 can be smoothly guided from the interior of the threading core shaft component 7 to the exterior, preparing for the subsequent winding operation.

[0059] The driving cylinder of the core shaft adjustment assembly extends, and drives the threading tube of the threading core shaft component 7 to retreat in the rotating main shaft through the mobile baffle, so that the winding core shaft tooling is retracted into the interior of the die head through the first spring, and the sliding platform is controlled to move backward.

[0060] The winding tooling 322 in the rotating winding device is controlled to rotate 90° to change the working surface. The coil on the original working surface is first pressed onto the original working surface by the pressure wheel 55 on the pressure wheel component 5. When it is rotated 90° again, the coil passing through the pressure wheel 55 is peeled off by the guide wire 42 in the wire guide component 4 and falls onto the conveyor line of the conveyor belt component 6 for discharge.

[0061] In this step, the coil is removed from the winding tooling 322 by the clamping wheel 55, and the coil is unloaded by the guide wire 42. Cutting operations can be performed between multiple groups of coils as needed. At the same time, the other unworked surface of the winding tooling 322 can also be cleaned, sprayed with a release agent, etc.

[0062] By combining the rotary winding device with the flying fork winding method, the coil can be wound continuously, solving the technical problem of the existing hollow cup motor requiring continuous winding when winding multiple sets of coils. Compared with the existing manual winding operation method, it can not only ensure the quality and consistency of the coil, but also significantly improve efficiency.

[0063] In addition, the structural design of the rotary winding device uses the winding tool 322 (tetrahedron structure) to wind the coil outlet on one side to the wire input on the next side. The straight-line distance in space is selected so that the connecting line between two adjacent groups of coils is shorter, meeting the requirements of multiple groups of continuous micro hollow cup motor coils and the intermediate connecting line cannot be too long.

[0064] This winding method can achieve continuous winding without wire breakage, and the connecting wires between each set of coils are relatively short, meeting the requirements of fully automated winding of small hollow cup motor coils.

[0065] Although the present invention is disclosed as above, the scope of protection disclosed by the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the scope of protection of the present invention.
