Description

Technical Field

[0001] This invention belongs to the field of wire winding technology, specifically, it relates to a wire winding method. Background Technology

[0002] In related technologies, a single continuous conductor winding method is used. This involves an operator or automatic winding machine sequentially winding a single conductor between layers and sections of coil within the same tooth groove. The conductor transitions uninterruptedly from the end of one coil to the beginning of the next, ultimately forming a complete series winding. This winding method suffers from problems such as long winding time, slow production cycle, and low efficiency if the number of turns is large. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of the present invention propose a winding method, which has the advantages of short winding time, fast production cycle, and high efficiency.

[0005] The winding method of this invention includes the following steps:

[0006] The ends of multiple wires are combed out, and the ends of the multiple wires are connected by connectors to form a wire bundle; The wire harness is pre-wound around the clamp at a predetermined position, with the predetermined position spaced apart from the connector. Start the winding device to drive the wire clamp to rotate and move, so that the wire bundle is synchronously wound onto the wire clamp; Once the predetermined number of turns is reached, the winding stops and the wire harness is cut. The wire harness has a connector at one end as the starting end and the cut end as the ending end. Remove the connector and connect the start end of at least one wire in the wire harness to the end end of another wire, so that the multiple wires are connected in series.

[0007] The winding method of this invention improves winding efficiency by utilizing parallel wire harnesses and achieves precise construction of the final electrical series relationship through flexible end connections. This improves production efficiency and shortens production cycle time while ensuring the electrical function of the winding.

[0008] In some embodiments, combing through the ends of multiple wires includes the following steps: The wires are fed using a wire feeder and a paralleling roller is provided. The paralleling roller includes a first roller and a second roller. A paralleling gap is defined between the first roller and the second roller. Wires from multiple wire feeders are led out through the paralleling gap.

[0009] In some embodiments, the distance between two adjacent feed reels is greater than the distance between the first roller and the second roller.

[0010] In some embodiments, the connector includes a plurality of connecting portions, which are connected one-to-one with the ends of a plurality of wires.

[0011] In some embodiments, a plurality of the connecting portions are arranged at intervals along the extending direction of the connector.

[0012] In some embodiments, the wire clamp has a winding area, the wire bundle is wound around the winding area, and the starting end and the ending end are located outside the winding area.

[0013] In some embodiments, after stopping the winding, the following steps are further included: The starting end and the ending end are located on the same side of the winding area, and the starting end of one conductor can be bent toward the ending end of the other conductor, and / or the ending end of one conductor can be bent toward the starting end of the other conductor.

[0014] In some embodiments, the sum of the distance from the starting end to the winding area and the distance from the ending end to the winding area is greater than the distance between the starting end and the ending end.

[0015] In some embodiments, after stopping the winding, the following steps are further included: The starting end and the ending end are located on different sides of the winding area, and the starting end of one conductor is electrically connected to the ending end of the other conductor.

[0016] In some embodiments, the electrical connection is made by at least one of welding, crimping, or wrapping. Attached Figure Description

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] like Figures 1-4 As shown, the winding method of this invention includes the following steps: The ends of multiple wires 2 are combed out and connected together through connector 5 to form a wire bundle.

[0024] Understandably, multiple independent conductors 2 are physically connected in parallel at their starting ends 21 (i.e., the wire ends) via a connector 5 (such as a detachable clamp, sleeve, or temporary solder joint). The connector 5 serves to bundle all the conductors 2 together into a single unit during the winding stage, forming a convenient wire bundle.

[0025] During the winding process, connector 5 is regarded as a fixed end of the wire harness, so that multiple wires 2 can be treated as a single thick wire, thereby achieving multi-wire synchronous winding, but electrically they are still in parallel (not forming a series circuit).

[0026] The preset position 12 on the wire harness is pre-wound onto the clamp 1, with the preset position 12 spaced apart from the connector 5.

[0027] It is understandable that, such as Figures 1-3 As shown, the preset position 12 of the wire harness (i.e., a point a certain distance behind the connector 5) is pre-wound or fixed on the wire clamp 1 (i.e., the winding mold or skeleton). The preset position 12 is spaced apart from the connector 5, so that the connector 5 itself is not wound into the coil, but remains outside the wire clamp 1.

[0028] Start the winding device to drive the wire clamp 1 to rotate and move, so that the wire harness is synchronously wound on the wire clamp 1.

[0029] Understandably, the wire clamp 1 is driven by the winding equipment to rotate or translate. The winding equipment (such as a winding machine) drives the wire clamp 1, and since the wire bundle is fixed at the preset position 12, the equipment only needs to feed the entire wire bundle as if handling a single wire 2. All wires 2, as part of the wire bundle, are wound synchronously and with the same number of turns onto the wire clamp 1. This achieves multi-wire parallel winding, improving winding efficiency.

[0030] Once the predetermined number of turns is reached, the winding stops and the wire harness is cut. The wire harness has a connector 5 at one end as the starting end 21 and the cut end as the ending end 22.

[0031] Understandably, after the winding is completed, the wire harness is cut, and the break point of the wire harness forms the end 22. At this time, the two ends of the wire harness are: the starting end 21 with connector 5 (parallel connection of multiple wires 2) and the ending end 22 formed by cutting (parallel connection of multiple wires 2).

[0032] Remove connector 5 and connect the start end 21 of at least one conductor 2 in the wire harness to the end end 22 of another conductor 2 so that multiple conductors 2 are connected in series.

[0033] Understandably, removing connector 5 breaks the temporary parallel connection of each wire 2 at its starting end 21, allowing each wire 2 to regain its independent end. Finally, by connecting the starting end 21 of at least one wire 2 to the ending end 22 of another wire 2 (e.g., by welding, crimping, etc.), the conversion of all wires 2 from physical parallel connection during winding to electrical series connection in the final product is achieved.

[0034] The winding method of this invention improves winding efficiency by utilizing parallel wire harnesses and achieves precise construction of the final electrical series relationship through flexible end connections. This improves production efficiency and shortens production cycle time while ensuring the electrical function of the winding.

[0035] It should be noted that, based on the winding method of this invention, different numbers of wires 2 can be selected for winding, such as two, three, or more. Specifically, when using two wires 2, as... Figures 1-3 As shown, the starting ends 21 of two wires 2 are connected and fixed together in parallel by a connector 5 to form a simple double-wire bundle. This bundle is then simultaneously wound around the clamp 1. Each turn of the winding device actually winds both wires 2 simultaneously.

[0036] After winding is complete, cut the wire bundle and remove connector 5. At this point, each of the two conductors 2 has an independent starting end 21 (the original parallel end) and ending end 22 (the cut end). Series connection is usually the most direct method: taking three conductors, namely conductor A and conductor B, connect the starting end 21 of conductor A to the ending end 22 of conductor B, ultimately forming a winding composed of two conductors 2 connected in series. The ending end 22 of conductor A and the starting end 21 of conductor B then become the two endpoints for the entire winding to connect externally.

[0037] In theory, using two wires reduces winding time by approximately 50% compared to single-wire winding. The efficiency improvement is significant and easy to implement. Furthermore, the wire harness is the simplest, and wire feeding and tension control are the easiest. The subsequent series connection logic is also the most straightforward, typically requiring only one connection operation. It is suitable for applications that require dividing the winding into two equal parts connected in series, or that require a specific two-wire structure (such as for increasing current capacity or specific inductor designs).

[0038] Alternatively, two or more wires can be used (e.g., three, four, or n wires). This demonstrates the scalability and flexibility of the method of the present invention.

[0039] The starting ends 21 of three (or more) wires 2 are connected and secured together in parallel by a connector 5 to form a multi-wire bundle. The connector 5 needs to be able to reliably secure more wire ends. The multi-wire bundle is wound synchronously. Each turn of the winding device simultaneously winds three (or n) wires 2.

[0040] After winding is complete, cut the wire bundle and remove connector 5. At this point, each of the multiple conductors 2 has an independent start end 21 and end end 22. The logic of series connection becomes more diverse, requiring multiple connections according to design requirements. For example, for a system containing three conductors 2, namely conductor 2A, conductor 2B, and conductor 2C, a possible series connection sequence is: connect the start end 21 of conductor 2A to the end end 22 of conductor 2B, and then connect the start end 21 of conductor 2B to the end end 22 of conductor 2C. Ultimately, the end end 22 of conductor 2A and the start end 21 of conductor 2C become the two ends of the winding. An "ABC" series path is formed internally. The number of connection operations is (number of conductors 2 - 1).

[0041] Therefore, the winding time can theoretically be reduced to about 1 / n compared to single-wire winding. For example, using 3 wires, the time is reduced by about 66%; using 4 wires, the time is reduced by about 75%. This is a huge improvement in the production efficiency of large coils with a very large number of turns.

[0042] Furthermore, the multiple wires 2 are bundled together, requiring assurance that they maintain uniform tension and a relatively orderly arrangement during winding to prevent internal tangling. A more sophisticated wire harness guiding mechanism may be necessary. The connector 5 needs to securely hold multiple wire ends simultaneously without damaging the wires 2 during removal. Subsequent precise connections according to the design sequence will require higher levels of automation and skilled operators.

[0043] The following examples all illustrate the winding method of two wires 2.

[0044] In some embodiments, combing the ends of multiple wires 2 includes the following steps: feeding wires 2 using a wire feeding reel 3 and setting a paralleling roller, the paralleling roller including a first roller 41 and a second roller 42, a paralleling gap being defined between the first roller 41 and the second roller 42, and the wires 2 on the multiple wire feeding reels 3 being led out through the paralleling gap.

[0045] Specifically, such as Figure 4 As shown, there are two feed reels 3, each independently carrying and supplying one continuous conductor 2. Multiple feed reels 3 correspond to multiple independent sources of conductor 2. The feed reels 3 are responsible for stably releasing the conductor 2 and providing the necessary tension control basis to ensure that each conductor 2 can be independently and smoothly fed before subsequent merging.

[0046] The first roller 41 and the second roller 42 are installed side by side, that is, the axial direction of the first roller 41 is parallel to the axial direction of the second roller 42. The space between the first roller 41 and the second roller 42 forms a parallel gap. The width and shape of the parallel gap can be predetermined according to the radial dimension of the conductor 2, etc.

[0047] Understandably, the multiple wires 2 leading from each wire feeder 3 are guided together to the paralleling gap, which serves as a channel and constraint mechanism for the wires 2 to pass through. In other words, the structure of the wire feeder 3 and the rollers is easily integrated into automated winding equipment. The wire feeder 3 provides a stable wire supply, and the paralleling rollers act as fixed mechanical guides. The entire winding process can be performed automatically and continuously, eliminating the need for frequent manual intervention to tidy up the loose wire ends, thus improving the stability of the production rhythm and the repeatability of the process.

[0048] Furthermore, the merging rollers (especially the gap between the two rollers) exert a slight physical constraint and guidance on the passing conductors 2. This helps to maintain a relatively parallel posture and similar tension when multiple conductors 2 are merged. It avoids the problem of unevenness and inconsistent tension within the wire bundle caused by arbitrary crossing and twisting of conductors 2 at the merging point.

[0049] Preferably, the distance between two adjacent wire feeding discs 3 is greater than the distance between the first roller 41 and the second roller 42.

[0050] It is understandable that, such as Figures 1-3 As shown, after the wire 2 is led out from the widely spaced wire feed reels 3, it is gradually brought together towards the paralleling roller under the guidance of the guiding device (which may include other guide wheels or pipes), and finally must all enter the paralleling gap which is narrower than the spacing of the wire feed reels 3.

[0051] In other words, due to the wide spacing between the wire feed reels 3, each wire 2 will inevitably form an inclined angle of incidence when it reaches the narrow paralleling gap from its respective wire feed reel 3. This angle causes the wire 2 to be smoothly guided by the side of the paralleling roller when it contacts the roller, and is pushed towards the center of the gap, rather than being bent into the gap at a sharp right angle, thereby reducing the bending stress and wear of the wire 2.

[0052] In some embodiments, the connector 5 includes a plurality of connecting parts, which are connected one-to-one with the ends of a plurality of wires 2.

[0053] Understandably, the multiple connecting parts on connector 5 are connected one-to-one with the multiple wires 2, allowing each wire 2 to have its tension applied or adjusted individually. For example, each connecting part can be a tiny gripper, slot, or pressure block with independent locking and fine-tuning capabilities. This ensures that the multiple wires 2 have a balanced and controllable initial tension at the starting point of being bundled together.

[0054] In other words, if a single connection point (such as a large solder joint or a large clip) fails, the entire wire harness will disintegrate, and the winding process will be completely interrupted. By using multiple independent connection points, a distributed connection system is formed. Even if one connection point becomes slightly weak due to an accident (such as a slight defect in a wire end), the other connection points can still remain firm, the integrity of the entire wire harness is maintained, and the fault tolerance of the production process is higher.

[0055] Therefore, after the winding is completed, connector 5 needs to be removed, and the ends of each conductor 2 need to be connected in series. If all the wire ends are mixed together, it is easy to get confused during disassembly, and it is difficult to accurately identify which wire is which during subsequent connections. However, the connectors that correspond one-to-one with each conductor 2 physically maintain the independence and order of each conductor 2 end. During disassembly, simply loosen each connector in sequence, and the conductors 2 will naturally separate, maintaining their original arrangement. This is crucial for subsequent operations that require series connection in a specific order (such as three or more conductors 2), simplifying the identification and connection process and improving accuracy.

[0056] Preferably, multiple connecting parts are arranged at intervals along the extension direction of the connector 5.

[0057] Understandably, the multiple connectors are spaced apart, providing independent physical space for clamping and securing each conductor 2's wire end. This avoids the tangling, squeezing, or friction that can occur when all wire ends are squeezed at the same point. It ensures that each conductor 2 is clearly defined and independent at the connector point, creating perfect conditions for subsequent independent tension control.

[0058] In some embodiments, the wire clamp 1 has a winding area 11, the wire harness is wound around the winding area 11, and the starting end 21 and the ending end 22 are located outside the winding area 11.

[0059] Specifically, such as Figures 1-3 As shown, the wire clamp 1 is roughly "I"-shaped, with a winding area 11 formed in the middle. The starting end 21 is the end of the wire harness with the connector 5. The ending end 22 is the end of the wire harness that is cut off after winding. Both are located outside the winding area 11, meaning that during the winding process, only the main part of the wire harness is wrapped inside the winding area 11, while the starting end 21 and the ending end 22 at both ends always remain outside the winding area 11 and are not wrapped inside.

[0060] Understandably, excluding the two ends of wire 2 from the winding area 11 prevents the ends (usually with connector 5 or a thicker cut) from getting mixed into the effective coil, thus ensuring the neatness of the main body of the coil and the consistency of electrical performance.

[0061] After winding is complete, the wire bundle needs to be cut at a specific location to form the end 22. If the location of the end 22 is difficult to determine or is surrounded by coil turns, the cutting operation will be very difficult and may damage the wound coil.

[0062] The specified end 22 is located outside the winding area 11, which ensures that the cutting point is on the outside, so that the cutting operation can be carried out in an open and easily accessible location. The operating tools (such as scissors or cutters) will not interfere with the coil inside the winding area 11, ensuring the convenience and safety of the operation.

[0063] Furthermore, after the coil is wound, the ends of each conductor 2 need to be connected in series. If the ends are buried inside the winding area 11, it will be very difficult to find and connect them. By leaving the starting end 21 and the ending end 22 outside the winding area 11, it is equivalent to reserving all the wire ends that need to be processed later in an open working area, thereby simplifying the subsequent connection process (welding, crimping, etc.) and improving work efficiency and reliability.

[0064] In some embodiments, after stopping the winding, the method further includes the following steps: the starting end 21 and the ending end 22 are located on the same side of the winding area 11, the starting end 21 of one conductor 2 can be bent toward the ending end 22 of another conductor 2, and / or, the ending end 22 of one conductor 2 can be bent toward the starting end 21 of another conductor 2.

[0065] Understandably, after the winding is completed, both the starting end 21 (the end with the connector 5) and the ending end 22 (the cut end) of the wire harness are led out to the same side of the winding area 11, such as the left or right side of the wire clamp 1. This places the two ends in the same spatial area, making it easier for them to approach each other.

[0066] Specifically, the starting end 21 of one conductor 2 (i.e., the end of the conductor 2 that extends from the connector 5) is bent toward the ending end 22 of the other conductor 2. That is, before completing the series connection, the two ends to be connected are brought closer or aligned to each other in space by physical bending.

[0067] Alternatively, the end 22 of one conductor 2 can be bent toward the beginning 21 of the other conductor 2. That is, before completing the series connection, the two ends to be connected are brought close to or aligned with each other in space by physical bending.

[0068] Alternatively, the starting end 21 of one conductor 2 (i.e., the end of the conductor 2 that extends from the connector 5) is bent toward the ending end 22 of the other conductor 2, and the ending end 22 of one conductor 2 is bent toward the starting end 21 of the other conductor 2. That is, a bidirectional bend, so that the ends of the two conductors 2 to be connected in series move toward each other and eventually meet at a certain point in the middle.

[0069] In other words, bending automatically aligns and brings the ends closer together, eliminating the need for operators or automated equipment to perform complex searching, pulling, or docking actions. This makes the connection point position clear and fixed, facilitating welding, crimping, and other operations, and is especially suitable for automated production lines, improving production speed and connection quality.

[0070] In some embodiments, the sum of the distance from the starting end 21 to the winding region 11 and the distance from the ending end 22 to the winding region 11 is greater than the distance between the starting end 21 and the ending end 22.

[0071] It is understandable that, such as Figure 3 As shown, the distance from the starting end 21 to the winding area 11 is a1 and a2, and the distance from the starting end to the ending end 22 is b. Therefore, a1 + a2 > b. That is to say, the starting end 21 and the ending end 22 on the same side can be bent towards each other, so that the starting end 21 of one wire 2 can overlap with the ending end 22 of another wire 2, thereby facilitating the fixing, welding, crimping and other operations of the wire 2.

[0072] In other words, the overlapping point formed by the bends of the two wires 2 allows them to meet in a smooth arc rather than a sharp angle. This not only reduces stress concentration and protects the wires 2, but also makes the overlapping part of the two wires 2 easier to weld, resulting in a neater connection and a more reliable connection.

[0073] In some other embodiments, after the winding is stopped, the following steps are also included: the starting end 21 and the ending end 22 are located on different sides of the winding area 11, and the starting end 21 of one conductor 2 is electrically connected to the ending end 22 of the other conductor 2.

[0074] Understandably, after winding, the starting end 21 and the ending end 22 of the coil are led out to different sides of the winding area 11. For example, the starting end 21 is on the left side of the clamp 1, while the ending end 22 is on the right side of the clamp 1. In this arrangement, the starting end 21 of one conductor 2 is directly connected to the ending end 22 of another conductor 2 by an electrical connection (such as welding, crimping, etc.). This means that the connection operation is performed without changing the original position of the ends (i.e., on different sides), and the connection point may be located above, below, or through other paths in the winding area 11.

[0075] In other words, in certain coil structures (such as certain motor tooth slots) or wire clamp 1 designs, leading the starting end 21 and the ending end 22 to the same side may require complex wire 2 paths or large bending angles. Allowing the ends to be on different sides allows for more natural utilization of the existing structure or space of the wire clamp 1 to lead out the wire 2, making the lead-out path more direct and shorter, thereby reducing unnecessary bending, reducing stress on the wire 2, and simplifying the design of the winding mechanism of the winding machine.

[0076] In some embodiments, the electrical connection method includes at least one of welding, crimping, or wrapping.

[0077] Understandably, different connection methods can be used depending on the application scenario of conductor 2. Welding offers the strongest connection with the lowest resistance, suitable for high-reliability, high-current applications. Crimping avoids heat-affected zones, suitable for temperature-sensitive applications or those requiring rapid connection. Winding is the simplest and lowest-cost method, suitable for certain traditional or specific coil requirements. Therefore, the most suitable method can be flexibly selected based on factors such as the final coil product's electrical performance, cost, and production environment.
