Description

Technical Field

[0001] This invention belongs to the field of winding technology, and specifically relates to a winding machine. Background Technology

[0002] As is well known, the wires on a magnetic coil generally need to be connected to the corresponding winding post. Magnetic coils are generally small in size. Although winding the wires onto the winding post achieves automatic winding, the wire end processing still relies on manual labor: the operator needs to manually cut the wire segment, bend it with pliers, and press it into the slot. This results in poor consistency and easily damages the wire. At the same time, the first turn of wire is not forced to adhere to the edge, which can easily lead to collapse or gaps. The tightness between the wire and the winding post is difficult to guarantee during manual winding, which can easily lead to inconsistent quality and make it difficult to control the finished product quality. Summary of the Invention

[0003] (1) Technical problems to be solved

[0004] This invention discloses a winding machine, which aims to solve the problems of low winding production efficiency and the first winding not adhering to the edge.

[0005] (2) Technical solution

[0006] This invention discloses a winding machine, including a frame. The frame is provided with a wire feeding mechanism for conveying enameled wire and a fixing mechanism for controlling the movement and rotation of the wire bobbin for winding. The fixing mechanism is provided with a clamping member that rotates synchronously with the wire bobbin. The fixing mechanism drives the wire bobbin and the clamping member to rotate, so that the enameled wire is wound around the winding portion of the wire bobbin to form a coil group. The first wire segment of the coil group is clamped on the clamping member, and the last wire segment of the coil group is connected to the wire feeding mechanism.

[0007] The wire frame includes a mounting base with a mounting groove. The mounting groove includes a first connecting groove and a second connecting groove arranged in parallel. The frame is also provided with a positioning mechanism and a cutting mechanism for cutting the wire. The cutting mechanism and the positioning mechanism jointly squeeze the first wire segment and the last wire segment, so that the first wire segment and the last wire segment are respectively embedded into the first connecting groove and the second connecting groove.

[0008] Furthermore, the shearing mechanism includes a bending member, a shearing clamp, and a positioning clamp. The positioning mechanism includes a positioning rod. When the positioning clamp presses the first line segment, the positioning rod vertically aligns the first line segment with the first connecting groove and is parallel to the extension direction of the first connecting groove. Subsequently, the bending member vertically embeds the aligned first line segment into the first connecting groove.

[0009] Furthermore, the bent component is provided with a groove, which is adapted to the shape of the first line segment.

[0010] Furthermore, the end of the positioning rod is provided with a recess that is adapted to the first line segment.

[0011] Furthermore, the first line segment is located on side A of the wire frame, i.e., the side closer to the mounting base, and the last line segment is located on side B of the wire frame, i.e., the side farther away from the mounting base.

[0012] Furthermore, the frame is also provided with a top edge mechanism, which includes a top edge member. When the top edge member presses the end line segment against the B side of the wire frame, the groove of the bending member is aligned with the end line segment and pressed vertically and parallel into the second connecting groove.

[0013] Furthermore, the top edge member is provided with an inclined surface, which is adapted to the shape of the winding portion.

[0014] Furthermore, both the first connecting groove and the second connecting groove are provided with metal plates, and the first line segment is vertically embedded and snapped into the first connecting groove and abuts against the metal plate.

[0015] Furthermore, the fixing mechanism is also provided with a pressing mechanism, which includes a pressing member. The pressing member is used to press the bent end segment, which is vertically parallel to the second connecting groove, into the second connecting groove and abut against the metal sheet.

[0016] Furthermore, the extending directions of the first connecting groove and the second connecting groove are perpendicular to the axial end face of the coil group.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. Through the coordinated operation of the shearing mechanism, positioning mechanism and top edge mechanism, the shearing, straightening, bending and crimping of the first / last line segment are integrated, replacing the traditional manual operation. The operation process does not require manual intervention, eliminating random errors in manual threading, cutting and bending, improving coil consistency, improving efficiency while saving time and labor costs.

[0019] 2. By designing a top edge mechanism, the wire is pressed against the edge during the initial winding to prevent collapse. The starting point of the enameled wire is precisely limited to the edge of the winding part near the flange, eliminating manual threading errors and avoiding collapse or lifting of the first loop due to wire slack. This ensures that the first loop fits the flange part with zero gap and also serves to fix the wire during the final wire segment processing. Attached Figure Description

Detailed Implementation

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] like Figure 1-17 As shown, the present invention discloses a winding machine, including a frame 1. The frame 1 is provided with a wire feeding mechanism 11 for conveying enameled wire 53 and a fixing mechanism 2 for controlling the movement and rotation of the wire frame 5 for winding. The fixing mechanism 2 is provided with a clamping member 23 that rotates synchronously with the wire frame 5. The fixing mechanism 2 drives the wire frame 5 and the clamping member 23 to rotate, so that the enameled wire 53 is wound around the winding part 51 of the wire frame 5 to form a coil group 55. The first wire segment 531 of the coil group 55 is clamped on the clamping member 23, and the last wire segment 532 of the coil group 55 is connected to the wire feeding mechanism 11.

[0040] The wire frame 5 includes a mounting base 52, and the mounting base 52 is provided with a mounting groove 521. The mounting groove 521 includes a first connecting groove 5211 and a second connecting groove 5212 arranged in parallel. The frame 1 is also provided with a positioning mechanism 4 and a cutting mechanism 3 for cutting wires. Metal sheets 54 are provided in both the first connecting groove 5211 and the second connecting groove 5212.

[0041] In use, the shearing mechanism 3 and the positioning mechanism 4 jointly squeeze the first wire segment 531 and the last wire segment 532, respectively, so that the first wire segment 531 and the last wire segment 532 are respectively embedded into the first connecting groove 5211 and the second connecting groove 5212 and abut against the metal sheet 54. The first wire segment 531 and the last wire segment 532 that abut against the metal sheet 54 are enameled wires 53 after the insulating varnish has been removed.

[0042] Preferably, such as Figure 4-5 The extension wire of the enameled wire 53 on the wire feeding mechanism 11 is first clamped onto the clamping member 23, and then wound on the winding part 51 to form a coil group 55. Therefore, the enameled wire 53 clamped in the clamping member 23 needs to be cut by the cutting clamp 32 to form the first wire segment 531. Then the first wire segment 531 is pressed into the connecting groove 5211 and abuts against the metal sheet 54. Welding is then carried out through subsequent welding processes to prepare for subsequent welding. The enameled wire 53 of the clamping member 23 after cutting is waste material. In this embodiment, the clamping member 23 and the mounting base 52 rotate synchronously and are adjacent. Through this design, the loss of enameled wire 53 material can be reduced, saving costs.

[0043] Furthermore, such as Figure 5 As shown, the wire frame 5 also includes flange portions 56 located on both sides of the winding portion 51. The diameter of the flange portion 56 is larger than the diameter of the winding portion 51. In this embodiment, the winding portion 51 and the flange portion 56 are integrally formed, but they can also be designed separately to prevent the wound coil group 55 from falling off from both sides of the winding portion 51.

[0044] Furthermore, such as Figure 6-7 As shown, the fixing mechanism 2 also includes a rotating component 21 and a rotating component 22 fixedly connected to the output shaft of the rotating component 21. The clamping component 23 is fixedly connected to the rotating component 22. The rotating component 22 includes a rotating cylinder 221 and a baffle 222. The baffle 222 is located on the side away from the clamping component 23. In use, the wire frame 5 is sleeved on the rotating cylinder 221, and then the baffle 222 is fixedly connected to the rotating cylinder 221, thereby fixing the wire frame 5 to the fixing mechanism 2.

[0045] Furthermore, such as Figure 8-9 As shown, the shearing mechanism 3 includes a bending member 31, a shearing clamp 32 and a positioning clamp 33, the positioning mechanism 4 includes a positioning rod 41, the clamping member 23 clamps the enameled wire 53 extending from the wire feeding mechanism 11, and the fixing mechanism 2 rotates to wind the enameled wire 53 onto the winding part 51.

[0046] like Figure 10-13As shown, the enameled wire 53, subsequently cut and clamped by the clamping member 23, forms the first wire segment 531. When the positioning clamp 33 presses one side of the first wire segment 531, the positioning rod 41 on the other side moves the first wire segment 531, applying a certain pressure so that the first wire segment 531 is vertically aligned with the connecting groove 5211 and parallel to the extension direction of the connecting groove 5211. Then, the bending member 31 vertically inserts the aligned first wire segment 531 into the connecting groove 5211 and abuts against the metal sheet 54. After the insulating varnish is removed from the first end of the enameled wire 53, it forms physical contact with the metal sheet 54, providing a reliable foundation for subsequent welding or direct use as an electrical connection point. At the same time, this design realizes fully automated feeding, winding, bending, and cutting operations, improving production efficiency and reducing the error of manual winding.

[0047] The entire process of the first wire segment 531, including cutting, initial fixing, precise positioning, and bending and embedding, is automatically completed by the cutting mechanism 3 and the positioning mechanism 4 under machine control. There is no need for manual intervention in the tedious steps of cutting, alignment, and bending, which significantly shortens the manufacturing cycle of a single coil group 55 and improves production efficiency. The first wire segment 531 is fully automated, completing all the key steps from cutting to final fixed connection. This design ensures that the first wire segment 531 is accurately and reliably placed in the predetermined position connecting slot 5211 and forms good contact with the metal sheet 54 through precise mechanical positioning and the straightening and alignment of the action positioning rod 41 and the vertical embedding of the bent part 31. This ultimately achieves high-quality, high-efficiency, and high-consistency production of coil groups 55.

[0048] Furthermore, the bending member 31 is provided with a groove 311, which is adapted to the shape of the first line segment 531. In use, the groove 311 of the bending member 31 is aligned with the first line segment 531. When the bending member 31 applies pressure, the enameled wire 53 is pressed in and conforms to the contour of the groove 311. The bending member 31 moves to wrap the groove 311 of the first line segment 531 and constrain the first line segment 531, ensuring that it maintains a vertical posture during the process of being pushed towards the connecting groove 5211.

[0049] Furthermore, the shearing mechanism 3 also includes a rotating component 34 and a connecting component 35 fixedly connected to the output shaft of the rotating component 34. The bending component 31, the shearing clamp 32, and the positioning clamp 33 are disposed on the connecting component 35. The extension direction of the bending component 31 is perpendicular to the extension direction of the shearing clamp 32. The positioning clamp 33 is located below the bending component 31, and the extension direction of the positioning clamp 33 is parallel to the extension direction of the shearing clamp 32. The rotating component 34 drives the connecting component 35 to rotate and switch the bending component 31, the shearing clamp 32, and the positioning clamp 33 to work. The core functional components of bending, shearing, and positioning are integrated on the same rotating connecting component 35. By switching the rotation, independent drive or linear movement mechanisms are replaced. Only one rotating component 34 needs to be controlled to complete the call of the three tools, simplifying the control system, improving response speed and reliability, and greatly saving equipment space. Shearing requires the blade to be parallel to the wire for cutting, and bending requires force applied in a specific direction. The vertical layout avoids action interference and avoids multi-axis motion interference. At the same time, it is convenient to maintain and replace when the parts are damaged.

[0050] Preferably, the cut first wire segment 531 is at a certain angle to the connecting groove 5211 in a free state. The end of the positioning rod 41 is provided with a recess 411 that is adapted to the first wire segment 531. During use, the positioning clamp 33 presses one end of the first wire segment 531 tightly, while the other extended side cannot be inserted by bending member 31 because it forms a certain angle with the connecting groove 5211. Therefore, the recess 411 of the positioning rod 41 abuts against the middle of the extended first wire segment 531 to apply a certain pressure and push it straight into a vertical state. The recess 411 is designed to avoid slippage when pressure is applied, and at the same time disperse the pressure to prevent local crushing of the wire or damage to the insulating varnish.

[0051] Specifically, the first line segment 531 is located on the A side of the wire frame 5, that is, the side close to the mounting base 52, and the last line segment 532 is located on the B side of the wire frame 5, that is, the side away from the mounting base 52.

[0052] Furthermore, such as Figure 14-16As shown, the mounting groove 521 includes the connecting groove 5212 corresponding to the end wire segment 532. After winding, the enameled wire 53 is not yet cut and connected to the coil group 55. The other end is connected to the wire feeding mechanism 11. The fixing mechanism 2 moves in a vertically aligned manner with the wire feeding mechanism 11, causing the enameled wire 53 to be in a vertically straight state. Subsequently, the fixing mechanism 2 moves. A top edge mechanism 7 is provided on one side of the positioning mechanism 4 on the frame 1. The top edge mechanism 7 includes a top edge component 71. The fixing mechanism 2 moves to make it... The top edge member 71 presses the vertical enameled wire 53. At this time, the enameled wire 53 that is not pressed into the coil group 55 is vertically aligned with the second connecting groove 5212. The top edge member 71 presses the end segment 532 against the B side of the wire frame 5. After the groove 311 of the bending member 31 is aligned with the end segment 532 and the enameled wire 53 is inserted, the bending member 31 rotates 90 degrees under the drive of the second rotating member 34, causing the vertical enameled wire 53 to rotate and bend its end segment 532 vertically and parallelly into the second connecting groove 5212.

[0053] Preferably, since the final wire segment 532 is abutted and fixed by the top edge member 71, the fixing mechanism 2 moves laterally to achieve the above function. When pressing the wire laterally, the top edge member 71 will hit the winding part 51. In order to avoid the coil group 55 after winding being damaged by impact, the top edge member 71 is provided with a slope 711. The slope 711 is adapted to the shape of the winding part 51, so that the wire will not be squeezed and deformed, saving costs and conforming to the structural design.

[0054] Furthermore, such as Figure 9 As shown, when the bending member 31 bends the end segment 532 and presses it into the connecting groove 2 5212, the end segment 532 and the metal sheet 54 may not make good contact, and the contact may not be in place. In order to avoid the incomplete contact affecting the welding quality, the fixing mechanism 2 is also provided with a pressing mechanism 24. The pressing mechanism 24 includes a pressing member 241. The pressing member 241 is used to press the end segment 532, which is bent and vertically parallel to the connecting groove 2 5212, into the connecting groove 2 5212 to contact the metal sheet 54. Finally, the shearing clamp 32 cuts the uncut end segment 532 so that its height is slightly higher than the height of the metal sheet 54. This design saves materials and improves the welding accuracy, preparing for subsequent welding.

[0055] It should be noted that, in addition to pressing the last segment 532, the top edge member 71 also presses the first turn of the enameled wire 53 against the flange portion 56 for winding. The top edge mechanism 7 also includes a drive member 72, the output shaft of which is fixedly connected to the top edge member 71. Since the starting end of the winding coil group 55 in this embodiment is close to the mounting base 52, the drive member 72 drives the top edge member 71 to approach the first segment 531 of the enameled wire 53 to be wound. Through this design, the top edge mechanism 7 enables the enameled wire 53 to be wound. The first loop is close to the edge of the winding part 51, which is in contact with the flange part 56. In use, the drive component 72 pushes the top edge component 71 to move horizontally, forcibly pressing the first segment 531 of the enameled wire 53 towards the mounting base 52. The starting point of the enameled wire 53 is precisely limited to the edge of the winding part 51 near the flange part 56, eliminating manual threading errors. After contacting the enameled wire 53, the top edge component 71 maintains a slight pressure state, so that the enameled wire 53 has a low tension and straight state before the first loop is wound, avoiding the collapse or lifting of the first loop due to wire slack, and ensuring that the first loop is in zero gap contact with the flange part 56.

[0056] It is important to note that the top edge action and the start of the rotating component 21 are strictly synchronized. First, the top edge component 71 presses the enameled wire 53 to the edge of the winding part 51; second, the rotating component 21 rotates the first turn at low speed; finally, the top edge component 71 retracts, the fixing mechanism 2 enters high-speed mode, the first turn of winding is completed under controlled conditions, and subsequent windings are seamlessly connected, preventing the positioning failure of the first turn due to the softness of the wire, and preventing the situation where the position deviation of the first turn significantly affects the leakage inductance and distributed capacitance. In addition, the first turn is attached to the edge, which can prevent the paint from seeping into the interlayer gap during the enamel impregnation.

[0057] It should be noted that in this embodiment, the extension directions of the first connecting groove 5211 and the second connecting groove 5212 are perpendicular to the axial end face of the coil group 55. This design allows the first wire segment 531 and the last wire segment 532 to enter the wire perpendicularly, and at the same time facilitates the subsequent welding process, resulting in better subsequent welding.

[0058] like Figure 17 The diagram shows the first segment 531 and the last segment 532 being pressed into the first connecting groove 5211 and the second connecting groove 5212 respectively after winding.

[0059] like Figure 3 As shown, the frame 1 is also provided with a multi-directional moving mechanism 6, which includes an X-axis moving mechanism 61, a Y-axis moving mechanism 62, and a Z-axis moving mechanism 63. The multi-directional moving mechanism 6 can drive the frame 1 top edge mechanism 7, fixing mechanism 2, pressing mechanism 24, positioning mechanism 4 and other mechanisms to move along the XYZ axis so that they reach the corresponding positions.

[0060] The working principle of the present invention will be explained in detail below;

[0061] The wire frame 5 is fitted onto the rotating cylinder 221 of the fixing mechanism 2 and locked in place by the baffle 222, ensuring that the wire frame 5 rotates synchronously with the clamping member 23. The wire feeding mechanism 11 feeds the enameled wire 53, and its extended end is clamped by the clamping member 23. The driving member 72 pushes the top edge member 71 to move horizontally, pressing the first end of the enameled wire 53 against the edge of the winding part 51, close to the flange part 56. The fixing mechanism 2 rotates and moves at low speed to complete the first turn of winding. The top edge member 71 maintains slight pressure to ensure that the coil is close to the edge without loosening. The top edge member 71 retracts, and the fixing mechanism 2 switches to high-speed mode to complete the winding of the coil group 55. After the winding is completed, the last segment 532 of the enameled wire 53 is still connected to the wire feeding mechanism 11. The cutting clamp 32 of the cutting mechanism 3 cuts the enameled wire 53 at the clamping member 23 to form the first segment 531. Positioning clamp 33 presses one side of the first line segment 531, and the recess 411 of positioning rod 41 abuts against the other side, applying pressure to adjust it to a vertical state, aligning it with connecting groove one 5211. The groove 311 of bending piece 31 wraps around the first line segment 531, vertically embedding it into connecting groove one 5211, abutting against metal sheet 54. Then, top edge piece 71 presses the vertical last line segment 532 against the line frame B side. The groove 311 of bending piece 31 is inserted into the last line segment 532, rotated 90° to bend it into a vertical direction, parallel to connecting groove two 5212. Pressing edge piece 241 presses the bent last line segment 532 into connecting groove two 5212, ensuring full contact with metal sheet 54. Cutting clamp 32 cuts off the last line segment 532, leaving a height slightly higher than metal sheet 54 to reserve space for welding.

[0062] The innovation of this invention lies in the integrated processing of cutting, straightening, bending, and crimping of the first and last wire segments through the coordinated use of a cutting mechanism, a positioning mechanism, and a top edge mechanism. This replaces traditional manual operation, eliminating the need for human intervention and random errors associated with manual threading, cutting, and bending. It improves coil consistency, increases efficiency, and saves time and labor costs. The top edge mechanism is designed to prevent coil collapse during initial winding by pressing the wire against the edge. The starting point of the enameled wire is precisely limited to the edge of the winding section near the flange, eliminating errors caused by manual threading and preventing the first coil from collapsing or lifting due to wire slack. This ensures a zero-gap fit between the first coil and the flange, and also serves to fix the wire during the processing of the last wire segment.

[0063] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.

[0064] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
