Description

Technical Field

[0001] This utility model relates to winding equipment, and more particularly to a wire feeding mechanism and a winding device having the same. Background Technology

[0002] Winding equipment is a key piece of equipment in the production of electronic components such as motors, inductors, and transformers. One of its core functions is to wind conductors (such as copper wire) onto a specified magnetic core. As an important component of the winding equipment, the performance of the wire feeding mechanism directly affects the winding speed, accuracy, and quality of the final product.

[0003] In some applications, such as winding closed magnetic cores, to improve production efficiency, it is often necessary to wind coils simultaneously on both side posts of the closed magnetic core. Some winding equipment in related technologies also includes wire feeding mechanisms capable of simultaneously transporting two wires. However, in these mechanisms, the wire is transported solely by the feed rollers, resulting in an unstable wire transport process. Furthermore, these mechanisms typically use a single drive motor that drives two sets of feed rollers simultaneously via a transmission device (such as gears or synchronous belts). This necessitates that the transport speed and start / stop actions of the two wires be completely synchronized, making independent control impossible. In some complex winding processes, different tensions, start / stop timings, or transport speeds may be required for the two wires, making this approach unsuitable for highly flexible production needs. Summary of the Invention

[0068] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0069] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0071] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0072] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0074] The wire feeding mechanism and winding device having the same are described in detail below with reference to the accompanying drawings.

[0075] Reference Figures 1 to 8 As shown, the wire feeding mechanism provided according to the embodiment of the present utility model includes a carrier 10, a wire feeding channel component, a first driving wheel 30, a second driving wheel 31, a first driven wheel 40, a second driven wheel 41, a first driving device 50, and a second driving device 51.

[0076] Specifically, the carrier 10 can be made of high-strength metal materials, such as steel plates or aluminum alloys, to ensure sufficient rigidity and stability during use. In practical applications, the carrier 10 can be mounted on the frame of the winding equipment.

[0077] The wire feeding channel component provides a stable guiding path for the wire. It is mounted on the carrier 10 and extends along a first horizontal direction. The component has two parallel wire feeding channels H20, which guide the first and second wires respectively. The cross-sectional shape of each wire feeding channel H20 is adapted to the wire; for example, if the wire is flat, the cross-section of the wire feeding channel H20 is also a flat rectangle to ensure that the wire slides smoothly within the channel H20 without coming out.

[0078] The cable delivery channel assembly includes at least two channel elements 20, which are arranged sequentially along a first horizontal direction, with a gap P20 between adjacent channel elements 20. The channel elements 20 are strip-shaped, and the width of the gap P20 ensures sufficient space for the installation of the power delivery assembly while preventing excessive sag or deviation of the cable as it passes through the gap P20.

[0079] The first drive wheel 30 and the second drive wheel 31 are located in the interval P20 and are arranged side by side below the wire feeding channel in the second horizontal direction. The first drive wheel 30 corresponds to one of the two wire feeding channels H20, and the second drive wheel 31 corresponds to the other of the two wire feeding channels H20. The second horizontal direction is perpendicular to the first horizontal direction, so that the axes of the first drive wheel 30 and the second drive wheel 31 are perpendicular to the wire feeding direction.

[0080] A first driven wheel 40 and a second driven wheel 41 are located in the interval P20 and are arranged side by side above the wire feeding channel in the second horizontal direction. The first driven wheel 40 corresponds to the first driving wheel 30 and is used to press the first wire onto the first driving wheel 30. The second driven wheel 41 corresponds to the second driving wheel 31 and is used to press the second wire onto the corresponding second driving wheel 31.

[0081] In other words, the first driving wheel 30 and the second driving wheel 31 are arranged side by side in the second horizontal direction, each corresponding to a wire feeding channel H20. The first driving wheel 30 contacts the lower surface of the first wire through its outer circumferential surface, and the second driving wheel 31 contacts the lower surface of the second wire through its outer circumferential surface. The first driven wheel 40 is arranged vertically to correspond with the first driving wheel 30, forming a pair of cooperating power transmission components. The second driven wheel 41 is arranged vertically to correspond with the second driving wheel 31, forming another pair of cooperating power transmission components. The main function of the first driven wheel 40 is to press the wire against the corresponding first driving wheel 30, and the main function of the second driven wheel 41 is to press the wire against the corresponding second driving wheel 31. The pressing force ensures that the first driving wheel 30 and the second driving wheel 31 can reliably drive the wire forward.

[0082] The first driving device 50 is used to drive the first driving wheel 30 to rotate, and the second driving device 51 is used to drive the second driving wheel 31 to rotate; the first driven wheel 40 is pivotable about its own axis, and the second driven wheel 41 is pivotable about its own axis.

[0083] In actual operation, the first wire enters the first wire feeding channel H20 from one end of the wire feeding channel component and moves forward smoothly under the guidance of the first wire feeding channel H20. When the first wire reaches the first interval P20, its lower surface contacts the first driving wheel 30, and its upper surface is pressed by the first driven wheel 40, forming a reliable clamping state. The first drive device 50 drives the first driving wheel 30 to rotate, and the first wire is conveyed forward by friction. After the first wire leaves the first interval P20, it continues to move forward under the guidance of the next channel component 20, and so on, to achieve continuous and stable conveying. The conveying process of the second wire is similar to that of the first wire, but it is independently controlled by the second driving wheel 31, the second driven wheel 41, and the second drive device 51. This design not only ensures the stability and reliability of wire conveying, but also realizes the independent control of the two wires, meeting the needs of complex winding processes.

[0084] According to the wire feeding mechanism provided in this embodiment of the utility model, the wire is continuously guided by segmented wire feeding channel components. A pair of driving and driven wheels is set in the interval P20 between adjacent channel components 20, forming a multi-point support conveying mode that combines guiding, clamping, and directing. Compared to conveying methods relying solely on wire feeding wheels, this effectively improves the stability and reliability of the wire conveying process and effectively avoids wire shaking, deviation, or slippage during high-speed wire feeding. Furthermore, by configuring independent drive devices (i.e., first drive device 50 and second drive device 51) for the first driving wheel 30 and the second driving wheel 31 respectively, the two wires can be relatively independently controlled in terms of speed, tension, and start / stop timing, greatly improving the production flexibility of the equipment and enabling it to adapt to various complex winding process requirements.

[0085] Reference Figures 1 to 3 As shown, in some embodiments of the present invention, the wire feeding mechanism further includes a lifting device 60, which is used to drive the first driven wheel 40 and the second driven wheel 41 to switch between a first position and a second position in the vertical direction.

[0086] When the first driven wheel 40 and the second driven wheel 41 are in the first position, the first driven wheel 40 presses the first wire onto the first driving wheel 30, and the second driven wheel 41 presses the second wire onto the second driving wheel 31; when the first driven wheel 40 and the second driven wheel 41 are in the second position, the first driven wheel 40 separates from the first driving wheel 30, and the second driven wheel 41 separates from the second driving wheel 31.

[0087] In other words, when the lifting device 60 drives the first driven wheel 40 and the second driven wheel 41 to the first position, this position is the "pressing position" of the wire feeding mechanism. In this position, the first driven wheel 40 and the second driven wheel 41 are lowered to a preset height, allowing the first driven wheel 40 to reliably press the first wire onto the lower first driving wheel 30, while the second driven wheel 41 also reliably presses the second wire onto the lower second driving wheel 31. At this time, sufficient clamping force and friction are formed between the first driving wheel 30 and the first driven wheel 40, and between the second driving wheel 31 and the second driven wheel 41, ensuring stable wire feeding when the first driving device 50 drives the first driving wheel 30 to rotate and the second driving device 51 drives the second driving wheel 31 to rotate.

[0088] When threading, changing, troubleshooting, or equipment standby is required, the lifting device 60 can be activated to drive the first driven wheel 40 and the second driven wheel 41 as a whole to move vertically upwards until they reach the second position. This position is the separation position of the wire feeding mechanism. In this position, the first driven wheel 40 and the second driven wheel 41 are raised a certain distance, creating a clear gap between the lower edge of the first driven wheel 40 and the upper edge of the first driving wheel 30, completely separating them. Similarly, the second driven wheel 41 is also completely separated from the second driving wheel 31. At this time, the wire is no longer compressed and can be freely pulled or removed within the wire feeding channel H20.

[0089] By configuring the aforementioned lifting device 60, the operation process is greatly simplified and work efficiency is improved. When performing wire threading or replacement operations, operators only need to control the lifting device 60 to lift the first driven wheel 40 and the second driven wheel 41, quickly completing the wire arrangement or replacement and shortening equipment preparation and downtime maintenance time. Furthermore, it automates and standardizes the clamping state. The first and second positions of the lifting device 60 are preset, ensuring consistent and reliable pressure applied to the wire each time it is clamped. This avoids problems caused by excessive clamping force (damaging the wire) or insufficient clamping force (slippage during conveying) due to improper manual adjustment, thereby further ensuring the consistency of wire feeding accuracy and product quality.

[0090] Reference Figures 4 to 7 As shown, in some embodiments of this utility model, the wire feeding mechanism further includes a distance adjustment device 70, which is used to adjust the height position of the first driving wheel 30 and the second driving wheel 31 to change the gap between the first driving wheel 30 and the first driven wheel 40 and the gap between the second driving wheel 31 and the second driven wheel 41.

[0091] In practical applications, when it is necessary to change to wires of different diameters during production, such as from thinner to thicker wires, the operator can first use the lifting device 60 to raise the first driven wheel 40 and the second driven wheel 41 to a second position to facilitate threading. Subsequently, the operator uses the distance adjustment device 70 to appropriately lower the first driving wheel 30 and the second driving wheel 31, thereby increasing the gap between them and the first driven wheel 40 and the second driven wheel 41 in the clamping position to match the diameter of the thicker wire. Conversely, when changing to a thinner wire, the positions of the first driving wheel 30 and the second driving wheel 31 are adjusted accordingly. Furthermore, when processing the same type of wire but with different process requirements, for example, for more fragile or easily deformable wires, the first driving wheel 30 and the second driving wheel 31 can be slightly lowered to reduce clamping force and prevent damage to the wire surface; while for wires requiring high-speed conveying and prone to slippage, the first driving wheel 30 and the second driving wheel 31 can be slightly raised to increase clamping force and ensure reliable conveying.

[0092] In this embodiment, by adding the distance adjustment device 70, the applicability and versatility of the equipment are enhanced. This allows a single device to flexibly adapt to wires of different specifications and materials without replacing the core power delivery components, reducing production costs and equipment changeover time. Simultaneously, it enables precise fine-tuning of the clamping force, allowing operators to optimize wire feeding parameters according to specific process requirements. This effectively avoids wire damage or slippage caused by improper clamping force, thus ensuring the stability of the wire feeding process and the consistency of final product quality under varying production conditions, further enhancing the equipment's process adaptability.

[0093] Reference Figures 1 to 3 As shown, in one embodiment of the present invention, the lifting device 60 includes a sliding seat 601, a driven shaft 42 and a first linear drive module 602. The sliding seat 601 is slidably disposed on the carrier 10 in the vertical direction.

[0094] Driven shaft 42 is mounted on sliding seat 601 and extends along the second horizontal direction. The first driven wheel 40 and the second driven wheel 41 are respectively mounted on driven shaft 42 at intervals via bearings. Exemplarily, driven shaft 42 is fixed to sliding seat 601, and the first driven wheel 40 and the second driven wheel 41 are mounted on driven shaft 42 via their respective independent bearings. This allows both the first driven wheel 40 and the second driven wheel 41 to pivot freely around driven shaft 42, thus smoothly following the rotation of the wire when in contact with it, avoiding sliding friction damage to the wire surface. Simultaneously, the axial positions of the first driven wheel 40 and the second driven wheel 41 are fixed, ensuring they stably and accurately correspond to the lower first driving wheel 30 and the second driving wheel 31, guaranteeing the accuracy of the clamping position.

[0095] The first linear drive module 602 is connected to the sliding seat 601 and is used to drive the sliding seat 601 to slide in the vertical direction. The first linear drive module 602 may be, but is not limited to, a cylinder, a linear motor, an electric actuator, a lead screw slide driven by a servo motor, or other drive devices.

[0096] When the first linear drive module 602 is activated, its drive end extends or retracts, thereby directly driving the connected sliding seat 601 to slide up or down along the vertical guide rail. Since the first driven wheel 40 and the second driven wheel 41 are both mounted on the driven shaft 42 of the sliding seat 601, the vertical movement of the sliding seat 601 will synchronously drive the first driven wheel 40 and the second driven wheel 41 to rise or fall as a whole, precisely switching between the first position of clamping the wire and the second position of complete separation.

[0097] The lifting device 60 with the above-described structure simplifies the mechanical structure and improves the synchronicity and consistency of the lifting actions of the first driven wheel 40 and the second driven wheel 41, ensuring that the clamping and releasing states of the two wires can be synchronized. Furthermore, the lifting device 60 is automatically controlled, improving production efficiency and ease of operation.

[0098] Reference Figures 4 to 7 As shown, in one embodiment of the present invention, the distance adjustment device 70 includes a support 701 and an adjustment screw 702. The support 701 is slidably disposed on the frame 10 in the vertical direction and located below the sliding seat 601. The bottom of the support 701 is provided with a threaded hole.

[0099] An adjusting screw 702 is pivotally mounted on the carrier 10 about its own axis and extends in the vertical direction. The adjusting screw 702 is threadedly engaged with the threaded hole, and when the adjusting screw 702 is rotated, it can drive the support 701 to slide in the vertical direction. For example, the lower end of the adjusting screw 702 is pivotally mounted on the carrier 10 via a bearing.

[0100] The first drive wheel 30 is mounted on the support 701 via a first drive shaft, and the second drive wheel 31 is mounted on the support via a second drive shaft. Exemplarily, the first drive device 50 and the second drive device 51 are fixedly mounted on the support.

[0101] When the height of the first drive wheel 30 and the second drive wheel 31 needs to be adjusted, the operator rotates the handwheel 7021 at the end of the adjusting screw 702. The rotational motion of the adjusting screw 702 is converted into the vertical linear motion of the bearing seat 701 through the threaded joint. Specifically, when the adjusting screw 702 rotates in one direction, the bearing seat 701 rises smoothly vertically; when it rotates in the opposite direction, the bearing seat 701 descends smoothly. Because the first drive wheel 30, the second drive wheel 31, the first drive device 50, and the second drive device 51 are all mounted on the bearing seat 701, the raising and lowering of the bearing seat 701 will synchronously drive the first drive wheel 30, the second drive wheel 31, the first drive device 50, and the second drive device 51 to rise and fall as a whole. In this way, the gap between the first drive wheel 30 and the first driven wheel 40, and between the second drive wheel 31 and the second driven wheel 41, can be precisely changed, thereby adapting to wires of different diameters or finely adjusting the clamping force of existing wires.

[0102] In this embodiment, a distance adjustment device 70 is used, which cooperates with a bearing seat 701 and an adjusting screw 702. This structure achieves high-precision height adjustment through threaded transmission, and due to the self-locking characteristic of the threaded transmission, the adjusted position can be stably maintained, resulting in high reliability. Furthermore, the first drive wheel 30, the second drive wheel 31, the first drive device 50, and the second drive device 51 are integrated on the same bearing seat 701 for overall adjustment, ensuring the consistency of the height positions of the two power transmission components.

[0103] Preferably, the first driving wheel 30, the second driving wheel 31, the first driven wheel 40, and the second driven wheel 41 are all rubber-coated wheels. Using rubber-coated wheels significantly increases the coefficient of friction between the first driving wheel 30, the second driving wheel 31, the first driven wheel 40, and the second driven wheel 41 and the wire. When the first driving device 50 and the second driving device 51 drive the first driving wheel 30 and the second driving wheel 31 to rotate, this high friction ensures that the first driving wheel 30 and the second driving wheel 31 apply a stable and reliable driving force to the wire, effectively preventing wire slippage that may occur under high speed or high tension conditions, thereby ensuring the accuracy of the wire feeding length and speed.

[0104] On the other hand, the rubber layer of the rubber-coated wheel acts as a buffer and protector. The wires used in components such as motors and inductors, especially enameled wires, are covered with a very thin layer of insulating varnish. The integrity of this varnish directly affects the electrical performance and reliability of the final product. If a rigid metal wheel is used for direct clamping and conveying, even with proper pressure control, it is very easy to cause indentations, scratches, or even damage to the insulation layer on the wire surface. The elastic rubber layer, when in contact with the wire, can absorb and disperse the clamping force using its own flexibility, forming a flexible contact surface. This flexible contact effectively avoids hard impacts and stress concentration, thus ensuring sufficient clamping force while maximizing the protection of the wire surface integrity, making it particularly suitable for handling flat wires or surface-sensitive wires.

[0105] Reference Figures 1 to 3 As shown, in one embodiment of the present invention, there are at least three channel members 20, and at least two interval regions P20 are formed between the at least three channel members 20.

[0106] There are at least two first driving wheels 30 and at least two second driving wheels 31. The at least two first driving wheels 30 are arranged at intervals in the first horizontal direction, and the at least two second driving wheels 31 are arranged at intervals in the first horizontal direction. The at least two first driving wheels 30 correspond one-to-one with the at least two intervals P20, and each first driving wheel 30 and the second driving wheel 31 is located in a corresponding interval P20.

[0107] There are at least two first driven wheels 40 and at least two second driven wheels 41. At least two first driven wheels 40 correspond one-to-one with at least two first driving wheels 30, and at least two second driven wheels 41 correspond one-to-one with at least two second driving wheels 31.

[0108] That is, within each independent interval P20, two sets of power transmission components are configured: a first power transmission component consisting of a first driving wheel 30 and a first driven wheel 40, and a second power transmission component consisting of a second driving wheel 31 and a second driven wheel 41. The first and second power transmission components are arranged side by side in the second horizontal direction to form a set of power transmission components. In this way, multiple intervals P20 can form multiple sets of power transmission components arranged at intervals along the first horizontal direction.

[0109] As the wire travels within the wire feeding channel H20, it sequentially passes through the channel component 20, the first interval P20, the channel component 20 again, the second interval P20, and the channel component 20 again. The wire is precisely guided within each segment of the channel component 20, and within each interval P20, it is reliably held and driven by the power transmission assembly consisting of the first driving wheel 30 and the first driven wheel 40.

[0110] By employing a multi-point drive system, firstly, the overall driving force on the wire is enhanced, easily handling the demands of high-tension, high-speed conveying and effectively improving conveying reliability. Secondly, distributing the total clamping force across multiple clamping points reduces the clamping force required at each point, effectively preventing damage such as indentations and scratches on the wire surface caused by stress concentration, thus providing gentler protection for the wire. Finally, this multi-stage structure, with alternating guiding and clamping operations, offers stronger control over the wire's posture, maximizing the suppression of vibration or deviation during long-distance conveying, thereby ensuring high precision in wire length and position, meeting the stringent and precise requirements of winding processes.

[0111] Reference Figures 6 to 7 As shown, in one embodiment of the present invention, the first driving device 50 includes a first driving motor 501 and a first synchronous transmission component 502. The first driving motor 501 is connected to at least two first driving wheels 30 through the first synchronous transmission component 502 to drive at least two first driving wheels 30 to rotate synchronously.

[0112] The second drive device 51 includes a second drive motor 511 and a second synchronous transmission assembly 512. The second drive motor 511 is connected to at least two second drive wheels 31 through the second synchronous transmission assembly 512 to drive the at least two second drive wheels 31 to rotate synchronously. It is understood that the first synchronous transmission assembly 502 and the second synchronous transmission assembly 512 may be transmission structures such as drive components and wheel drive components.

[0113] By combining the first drive motor 501 with the first synchronous transmission assembly 502, on the one hand, the drive structure of the second drive motor 511 and the second synchronous transmission assembly 512 ensures the synchronization of all drive wheels on the same wire conveying path, preventing the risk of wire damage due to uneven speeds at various drive points and ensuring a smooth conveying process. On the other hand, compared to configuring a separate motor for each drive wheel, the drive structure is significantly simplified, the number of motors is reduced, thereby reducing manufacturing costs, saving installation space, and lowering structural complexity and failure rate. Furthermore, since the first drive device 50 and the second drive device 51 are independent of each other, while achieving efficient synchronous drive within a single channel, the advantage of independent control between the two wires is fully preserved, taking into account the reliability, economy, and flexibility of the wire feeding process.

[0114] Reference Figure 8As shown, in one embodiment of this utility model, the channel member 20 includes an upper channel plate 201 and a lower channel plate 202, and two wire feeding channels H20 are defined between the upper channel plate 201 and the lower channel plate 202. The two ends of the channel member 20 form pointed portions, and the interval region is formed between the pointed portions of two adjacent channel members 20.

[0115] In this embodiment, each channel component 20 is formed by stacking an upper channel plate 201 and a lower channel plate 202. The upper channel plate 201 and the lower channel plate 202 can be connected together by bolts or other detachable means, jointly defining the internal wire feeding channel H20. Preferably, two parallel grooves with cross-sectional shapes adapted to the wire to be fed are machined on the upper surface of the lower channel plate 202, while the lower surface of the upper channel plate 201 remains flat, serving as a cover plate covering the grooves. Thus, the flat lower surface of the upper channel plate 201 and the two grooves of the lower channel plate 202 together precisely form two independent, closed wire feeding channels H20.

[0116] This utility model embodiment also provides a winding device having a wire feeding mechanism as described in the above embodiment.

[0117] According to the winding device provided in this embodiment of the utility model, the wire is continuously guided by a segmented wire feeding channel component. A pair of driving and driven wheels is set in the interval P20 between adjacent channel components 20, forming a multi-point support conveying mode that combines guiding, clamping, and directing. Compared to conveying methods relying solely on the wire feeding wheel, this effectively improves the stability and reliability of the wire conveying process and effectively avoids wire vibration, deviation, or slippage during high-speed wire feeding. Furthermore, by configuring independent drive devices (i.e., first drive device 50 and second drive device 51) for the first driving wheel 30 and the second driving wheel 31 respectively, the two wires can be relatively independently controlled in terms of speed, tension, and start / stop timing, greatly improving the production flexibility of the equipment and enabling it to adapt to various complex winding process requirements.
