Description

Technical Field

[0001] This utility model relates to the field of winding machine technology, specifically to a wire nozzle with a wire cutting function. Background Technology

[0002] As the core equipment in the winding process, the winding machine's wire nozzle is a key component that runs through the entire winding process, playing a decisive role in product performance, production efficiency, and cost control. After the product is wound, the separation of the wire from the product is a crucial step in the winding process.

[0003] Currently, there are three main ways the connection can be lost:

[0004] 1. For wires with a finer diameter (such as 0.05mm), the method of directly tearing them is often used. However, this method can easily lead to excessively long tail wires, which require additional air shearing or manual trimming, increasing the process and cost.

[0005] 2. For wires with a general diameter (e.g., 0.6mm), a cutter or pneumatic shears are often used to cut the wire. The cutter is a vulnerable part of the winding machine and needs to be replaced in time after it wears out, which not only increases maintenance costs but also occupies equipment space. The pneumatic shears are large in size and have strict requirements on the internal space layout of the winding machine.

[0006] 3. For wires with a thicker diameter (such as 0.9mm), pneumatic shears are often used for cutting, which has problems such as large space occupation and high cost.

[0007] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0008] The purpose of this invention is to provide a wire tip with a tangent function.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A wire tip with a tangent function includes a fixed segment and a tangent segment connected together along a first direction, and also includes a wire hole that passes through the fixed segment and the tangent segment along the first direction;

[0011] The surface of the tangent segment has a portion of protrusions to form at least one tangent protrusion, which is used to cut the wire.

[0012] In the above scheme, the wire hole is used for passing and guiding the wire winding, while the fixing section is used to fix the wire nozzle. For example, the fixing section is connected to a structure in the winding machine, which is a conventional setting.

[0013] The fixed section and the tangent section are connected along the first direction. At the same time, the wire hole passes through the fixed section and the tangent section along the first direction, making the wire hole longer and improving the utilization of the wire tip.

[0014] Because the tangent segment has tangent protrusions, the wire can be cut directly using the tangent protrusions, avoiding the need for an additional cutter and reducing costs.

[0015] In summary, this application, by modifying the wire nozzle, achieves wire cutting without adding any structure, meeting the compact internal structure requirements of the winding machine and promoting its miniaturization. Furthermore, because the wire nozzle is closer to the wire, the distance that related components of the winding machine (such as the terminals and winding shaft) need to move during wire cutting is shorter, resulting in less time spent and improved winding efficiency.

[0016] In some implementations, the fixed section and the tangent section are integrally formed to improve the structural strength of the wire tip.

[0017] In a further technical solution, the tangent protrusions are provided in multiple forms, and each tangent protrusion is evenly distributed in a circular pattern around the axis of the tangent segment.

[0018] When the tangent is used frequently, its ability to cut wires will gradually decrease, thus requiring the wire tip to be replaced after a certain period of time.

[0019] Multiple tangential protrusions are provided, and each tangential protrusion can be replaced, extending the service life of the nozzle and further improving the utilization of the nozzle.

[0020] The tangential protrusions are evenly distributed in a circle around the axis of the tangential segment. During the wire cutting process, this arrangement allows the winding machine components to move a short distance to any tangential protrusion, avoiding the impact on the winding progress due to the replacement of each tangential protrusion.

[0021] In a further technical solution, the length direction of the tangent protrusion is the same as the length direction of the tangent segment.

[0022] The tangent protrusion can have several tangent areas. When the length direction of the tangent protrusion is the same as the length direction of the tangent segment, the utilization of the wire tip is further improved, and there are more tangent areas on the tangent protrusion, which extends the service life of the wire tip and further improves the utilization of the wire tip.

[0023] For ease of understanding, the tangent segment is described here as including the main body and the tangent protrusion. In some embodiments, the main body and the tangent protrusion have the same length.

[0024] In a further technical solution, in the first direction, the projection of the tangent segment is covered by the projection of the fixed segment.

[0025] In this embodiment, the projection of the tangential protrusion is covered by the projection of the fixed segment.

[0026] By setting the tangent segment in this embodiment, the size of the tangent segment is limited, avoiding the tangent segment being too large due to the tangent protrusion, thereby avoiding affecting the compact layout of the internal structure of the winding machine.

[0027] In a further technical solution, the fixed segment is set as a cylinder, the tangent segment is set as a triangular prism, and the junction of any two adjacent sides of the triangular prism constitutes a single tangent protrusion.

[0028] The fixed section is designed as a cylinder, which ensures the structural strength of the wire tip, facilitates processing, and requires less space.

[0029] The triangular prism has two bases and three lateral faces, and three tangential protrusions on the prism.

[0030] The triangular prism has relatively sharp edges, which form cutting protrusions to meet the requirements of cutting wire. Furthermore, the shape of the triangular prism ensures the structural strength of the wire tip. The material of the wire tip is based on existing materials and will not be elaborated here; it only needs to meet the requirements of cutting wire.

[0031] In a further technical solution, along the first direction, the wire hole has a first segment, a second segment, and a third segment connected in sequence;

[0032] The first segment and the third segment are funnel-shaped;

[0033] The wall portions of the first segment and the third segment are both smoothly connected to the wall portion of the second segment.

[0034] The first and third segments can be considered as the two ends of the wire hole.

[0035] The first and third sections are funnel-shaped, and the walls of the first and third sections are smoothly connected to the walls of the second section, which facilitates the wire to enter and exit the nozzle in a bent manner, while avoiding wire wear.

[0036] To avoid confusion, let's take the first paragraph as an example. Along the direction from the third paragraph towards the second paragraph, the size of the first paragraph gradually increases.

[0037] The terms "first," "second," etc., used in this article do not specifically refer to order or sequence, nor are they intended to limit this case; they are merely used to distinguish components or operations described using the same technical terms.

[0038] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0039] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0040] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0041] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms. In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0042] The working principle and advantages of this utility model are as follows:

[0043] In this application, the wire hole is used for passing and guiding the wire winding, while the fixing section is used to fix the wire nozzle, for example, the fixing section is connected to a structure in the winding machine.

[0044] The fixed section and the tangent section are connected along the first direction. At the same time, the wire hole passes through the fixed section and the tangent section along the first direction, making the wire hole longer and improving the utilization of the wire tip.

[0045] Because the tangent segment has tangential protrusions, the wire can be cut directly using these protrusions, eliminating the need for additional cutters or pneumatic shears, reducing costs, and optimizing the space required for such cutters or shears. The tangent protrusions also prevent frequent tailing of the wire.

[0046] In summary, this application, by modifying the wire nozzle, achieves wire cutting without adding any structure, meeting the compact internal structure requirements of the winding machine and promoting its miniaturization. Furthermore, because the wire nozzle is closer to the wire, the distance that related components of the winding machine (such as the terminals and winding shaft) need to move during wire cutting is shorter, resulting in less time spent and improved winding progress, thereby increasing the overall working efficiency of the winding machine.

[0051] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0052] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0053] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0054] See Figures 1-3 A wire tip with a tangent function includes a fixed section 1 and a tangent section 2 connected together along a first direction, and also includes a wire hole 3, wherein the wire hole 3 passes through the fixed section 1 and the tangent section 2 along the first direction;

[0055] The surface of the tangent segment 2 is partially raised to form at least one tangent protrusion 21, which is used to cut the wire.

[0056] The first direction is parallel to the x-direction in the diagram.

[0057] In the above scheme, the wire hole 3 is used for passing wire and guiding the wire winding, while the fixing section 1 is used to fix the wire nozzle. For example, the fixing section 1 is connected to a certain structure in the winding machine, which is a conventional setting.

[0058] The fixed segment 1 and the tangent segment 2 are connected along the first direction. At the same time, the wire hole 3 passes through the fixed segment 1 and the tangent segment 2 along the first direction, making the wire hole 3 longer and improving the utilization of the wire tip.

[0059] Because the tangent segment 2 has a tangent protrusion 21, the wire can be cut directly using the tangent protrusion 21, avoiding the need for additional cutters or pneumatic shears, reducing costs, and optimizing the space required for cutters or pneumatic shears. The tangent protrusion 21 also prevents frequent tail wire formation.

[0060] In summary, this application, by modifying the wire nozzle, achieves wire cutting without adding any structure, meeting the compact internal structure requirements of the winding machine and promoting its miniaturization. Furthermore, because the wire nozzle is closer to the wire, the distance that related components of the winding machine (such as the terminals and winding shaft) need to move during wire cutting is shorter, resulting in less time spent and improved winding progress, thereby increasing the overall working efficiency of the winding machine.

[0061] In some embodiments, the fixed segment 1 and the tangent segment 2 are integrally formed to improve the structural strength of the wire tip.

[0062] In some embodiments, a guide segment is also included. The guide segment is located at the end of the tangent segment 2 away from the fixed segment 1. The surface of the guide segment is an arc-shaped surface to avoid excessive wear when the wire moves along a predetermined arc-shaped path after leaving the wire hole 3.

[0063] See Figure 3 In this embodiment, the tangent protrusions 21 are provided in multiple ways, and each tangent protrusion 21 is evenly distributed in a circular pattern around the axis of the tangent segment 2.

[0064] When the tangent protrusion 21 is used frequently, its ability to cut wires will gradually decrease, thus requiring the wire tip to be replaced after a certain period of time.

[0065] Multiple tangential protrusions 21 are provided, and each tangential protrusion 21 can be replaced, extending the service life of the wire tip and further improving the utilization of the wire tip.

[0066] Each tangential protrusion 21 is evenly distributed in a circle around the axis of the tangential segment 2. During the cutting of the wire, this arrangement allows the winding machine components to move a short distance to any tangential protrusion 21, thus avoiding the impact on the winding progress due to the replacement of each tangential protrusion 21.

[0067] See Figure 1 In this embodiment, the length direction of the tangent protrusion 21 is the same as the length direction of the tangent segment 2.

[0068] The tangent protrusion 21 may have several tangent areas. When the length direction of the tangent protrusion 21 is the same as the length direction of the tangent segment 2, the utilization of the wire tip is further improved, and the tangent area on the tangent protrusion 21 is more, which extends the service life of the wire tip and further improves the utilization of the wire tip.

[0069] For ease of understanding, the tangent segment 2 is described here as including the main body 22 and the tangent protrusion 21. In some embodiments, the main body 22 and the tangent protrusion 21 have the same length.

[0070] See Figure 3In this embodiment, in the first direction, the projection of the tangent segment 2 is covered by the projection of the fixed segment 1.

[0071] In this embodiment, the projection of the tangent protrusion 21 is covered by the projection of the fixed segment 1.

[0072] By setting the tangent segment 2 in this embodiment, the size of the tangent segment 2 is limited, so as to avoid the tangent protrusion 21 from making the size of the tangent segment 2 too large, thereby avoiding affecting the compact layout of the internal structure of the winding machine.

[0073] See Figure 1 In this embodiment, the fixed segment 1 is set as a cylinder, the tangent segment 2 is set as a triangular prism, and the junction of any two adjacent side faces 5 in the triangular prism constitutes a single tangent protrusion 21.

[0074] The fixed section 1 is designed as a cylinder, which ensures the structural strength of the wire nozzle, facilitates processing, and requires less space.

[0075] See Figure 2 The triangular prism has two bases 4 and three sides 5, and has three tangential protrusions 21.

[0076] The triangular prism has relatively sharp edges, which form cutting protrusions to meet the requirements of cutting wire. Furthermore, the shape of the triangular prism ensures the structural strength of the wire tip. The material of the wire tip is based on existing materials and will not be elaborated here; it only needs to meet the requirements of cutting wire.

[0077] See Figure 1 In this embodiment, along the first direction, the wire hole 3 has a first segment 31, a second segment 32 and a third segment 33 connected in sequence;

[0078] The first segment 31 and the third segment 33 are funnel-shaped;

[0079] The wall portion of the first segment 31 and the wall portion of the third segment 33 are both smoothly connected to the wall portion of the second segment 32.

[0080] The first segment 31 and the third segment 33 can be regarded as the two ends of the wire hole 3.

[0081] The first segment 31 and the third segment 33 are flared, and the walls of the first segment 31 and the third segment 33 are smoothly connected to the walls of the second segment 32, which makes it easy for the wire to enter and exit the wire nozzle in a bent posture, while avoiding wire wear.

[0082] To avoid confusion, let's take the first segment 31 as an example. Along the direction from the third segment 33 toward the second segment 32, the size of the first segment 31 gradually increases.

[0083] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
