Description

Technical Field

[0001] The present invention relates to the technical field of winding methods, and more particularly to a winding method and a winding machine. Background Art

[0002] The inductor coil consists of a substrate and copper wire, and is insulated at the contact surface between the substrate and the copper wire. Currently, the production of inductor coils is generally achieved by a winding machine, which winds the copper wire onto the substrate according to a set winding method. The existing winding method is very simple and has not been improved much. There are many reasons for the simplicity of the winding method, such as insufficient equipment accuracy and insufficient development of new winding methods. The existing winding method also has some disadvantages, such as a high defective rate of the wound wire package, a high breakage rate, and an uneven appearance. The present invention proposes a new winding method to provide ideas for product development. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a winding method and a winding machine, provide multiple winding methods, and provide ideas for product development.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] The winding method, steps are as follows:

[0006] Clamping the annular substrate, selecting half or a quarter of the substrate, and winding the substrate with copper wire to form a first copper wire layer;

[0007] In one-half of the substrate, when the area of ​​the first copper wire layer is larger than one-quarter, the midpoint of the first copper wire layer coincides with the midpoint of one-half of the substrate, and the winding of one-quarter of the substrate is first completed using the unwound portion of one side of the copper wire wound around the first copper wire layer, and then the winding of the other quarter of the substrate is completed using the unwound portion of the other side of the copper wire wound around the first copper wire layer, thereby completing the winding of the other half of the substrate. Similarly, new copper wire is selected and wound around the other half of the substrate, and the number of copper wire winding layers around the substrate is greater than or equal to two layers.

[0008] In a quarter of the substrate, when the area of ​​the first copper wire layer is smaller than the quarter, the unwound portion on one side of the copper wire wound around the first copper wire layer is first used to complete the winding within the quarter of the substrate, and the unwound portion on the other side of the copper wire wound around the first copper wire layer is wound around the adjacent quarter of the substrate to form the first copper wire layer. Subsequently, the unwound portion of the copper wire in the adjacent quarter of the substrate is used to complete the winding within the quarter of the substrate, thereby completing the winding of one-half of the substrate. Similarly, a new copper wire is selected to wrap around the other half of the substrate, and the number of copper wire winding layers of the substrate is greater than or equal to two layers.

[0009] In one embodiment, the winding method includes the following steps:

[0010] A1. Hold the annular substrate and wrap a section of copper wire around the substrate starting from the winding position. Select half of the substrate and, starting from the starting point, wrap the copper wire around the substrate in a clockwise or counterclockwise direction to form the first copper wire layer. Divide the half of the substrate into two quarters at the midpoint of the first copper wire layer.

[0011] At this time, gaps are formed between adjacent copper wires in the first copper wire layer;

[0012] A2. Take the unwound copper wire on one side of one quarter of the substrate and wrap it once clockwise or counterclockwise on the gap formed by the adjacent copper wires in the first copper wire layer to form the second copper wire layer.

[0013] A3. After completing step A2, wrap the copper wire once more within the second copper wire layer to form gaps between adjacent copper wire portions within the second copper wire layer, and then wrap the copper wire once more within the gaps in the second copper wire layer to form a third copper wire layer.

[0014] A4. After completing step A3, if the number of copper wire layers required is three, return to the second copper wire layer and wind it once more to form new gaps between adjacent copper wire sections in the second copper wire layer, and then wind it once more around the new gaps in the second copper wire layer;

[0015] Repeat step A4 until the second copper wire layer and the third copper wire layer are wound in one quarter of the substrate; then proceed to step A6;

[0016] A5. After completing step A3, when the required number of copper wire layers is greater than three, if there are unfilled gaps between adjacent copper wires in the same layer, the next copper wire layer is wound around the unfilled gaps. When new gaps are formed in the next copper wire layer to fill the gaps, the newly formed gaps are filled first. The winding process continues until the required number of copper wire layers on the substrate is reached or no new gaps are formed. Then, the winding process returns to the second copper wire layer for further processing.

[0017] Repeat step A5 until the copper wire winding in one quarter of the substrate is completed; then proceed to step A6;

[0018] A6. Repeat steps A2-A5 in the opposite direction to step A2 to wrap the other quarter of the substrate in step A2, thereby completing the winding of the copper wire on half of the substrate.

[0019] A7. Repeat steps A1 to A6, and use another section of copper wire to wrap around the other half of the substrate, thereby completing the winding of the copper wire on the substrate.

[0020] In one embodiment, the winding method includes the following steps:

[0021] B1. Hold the annular substrate and wrap a section of copper wire around it once. Starting from the winding position of the copper wire and the substrate, select half of the substrate and wrap the copper wire around the substrate in a clockwise or counterclockwise direction to form the first copper wire layer. Divide the half of the substrate into two quarters at the midpoint of the first copper wire layer.

[0022] B2. Take the unwound copper wire on one side of one quarter of the substrate and wrap it again on the first copper wire layer to form a second copper wire layer.

[0023] B3. When the number of copper wire layers required is greater than two, within one-quarter of the substrate, after the second copper wire layer is wound, a new unwound portion of copper wire is formed outside the end of the second copper wire layer. The unwound portion of the second copper wire layer is wound around the substrate again in a direction opposite to the winding direction of the second copper wire layer to form a third copper wire layer. Otherwise, proceed directly to step B5.

[0024] B4. When the required number of copper wire layers is greater than three, continue winding the copper wire in the manner of step B3 until the number of copper wire layers within one-quarter of the substrate reaches the required number; otherwise, proceed directly to step B5.

[0025] B5. Repeat steps B2 to B4 to wrap the other quarter of the substrate in step B2, thereby completing the winding of the copper wire on half of the substrate;

[0026] B6. Repeat steps B1 to B5, using another section of copper wire to wrap around the other half of the substrate, thereby completing the winding of the copper wire on the substrate.

[0027] In one embodiment, the winding method includes the following steps:

[0028] C1. Hold the annular substrate and wrap the copper wire around it once. Starting from the location where the copper wire and the substrate are wrapped, select half of the substrate and divide the half into two equal quarters.

[0029] C2. Starting from the starting point, within one quarter of the substrate, the copper wire is first wound around the substrate in a clockwise or counterclockwise direction to form a first copper wire layer, and an unwound portion is formed outside the end of the first copper wire layer away from the starting point;

[0030] C3, the unwound portion of the copper wire outside the first copper wire layer is wound around the substrate again in a direction opposite to the winding direction of the first copper wire layer to form a second copper wire layer, and an unwound portion is formed outside the second copper wire layer;

[0031] C4. When the number of copper wire layers required is greater than two, the unwound portion of copper wire outside the second copper wire layer is wound around the substrate again in a direction opposite to the winding direction of the second copper wire layer to form a third copper wire layer; otherwise, the process proceeds directly to step C6;

[0032] C5. When the required number of copper wire layers is greater than three, continue winding the copper wire in the manner of step C4 until the number of copper wire layers within one-quarter of the substrate reaches the required number; otherwise, proceed directly to step C6.

[0033] C6. Wrap the copper wire around the substrate in the opposite direction to step C2 to form a first copper wire layer, then repeat steps C3 to C5 to wrap the other quarter of the substrate in step C2, thereby completing the winding of the copper wire around half of the substrate;

[0034] C7. Repeat steps C1 to C6, and use another section of copper wire to wrap around the other half of the substrate, thereby completing the winding of the copper wire on the substrate.

[0035] In one embodiment, the winding method includes the following steps:

[0036] D1. Hold the ring-shaped substrate and wrap the copper wire around it once. Using the winding position of the copper wire and the substrate as the starting point, select half of the substrate and divide the half into two equal quarters.

[0037] D2. Starting from the starting point, wrap the wire once clockwise or counterclockwise within one quarter of the substrate to form the first copper wire layer. Then, form gaps between adjacent copper wire sections within the first copper wire layer. Wrap the wire once more around the gaps to form the second copper wire layer.

[0038] D3. After completing step D2, if the number of copper wire layers required is two, return to the first copper wire layer and wind it once more, forming a new gap between adjacent copper wire portions within the first copper wire layer, and wind it once more in the new gap. Repeat step D3 until the winding of the first and second copper wire layers is completed within one-quarter of the substrate; then proceed to step D5.

[0039] D4. After completing step D2, when the required number of copper wire layers is greater than two, if there are unfilled gaps between adjacent copper wires in the same layer, the next copper wire layer is wound on the unfilled gaps. When new gaps are formed in the next copper wire layer to fill the gaps, the newly formed gaps are filled first. The winding process continues until the required number of copper wire layers on the substrate is reached or no new gaps are formed. Then, the winding process returns to the first copper wire layer for further winding.

[0040] Repeat step D4 until the copper wire winding in one quarter of the substrate is completed; then proceed to step D5;

[0041] D5. Wrap the copper wire around the substrate once in the opposite direction to step D2, then repeat steps D3-D4 to wrap the other quarter of the substrate in step D2, thus completing the wrapping of the copper wire around half of the substrate;

[0042] D6. Repeat steps D1 to D5, and use another section of copper wire to wrap around the other half of the substrate, thereby completing the winding of the copper wire on the substrate.

[0043] The winding machine can be applied to the above four different winding methods, including a frame and a winding module and a wire supply module arranged on the frame. The wire supply module is located above the winding module and provides copper wire to the winding module.

[0044] The winding module includes a rotating clamping mechanism, a wire hooking mechanism and a wire pulling mechanism. The base is clamped and fixed by the rotating clamping mechanism so that the base is placed flat above the wire hooking mechanism, which facilitates the hook needle of the wire hooking mechanism to pass through the base and pull down the copper wire. The wire pulling mechanism is located on the outside of the base and cooperates with the wire hooking mechanism to realize the winding of the copper wire on the base.

[0045] In one embodiment, the rotating clamping mechanism includes an upper base, a connecting frame, a rotating ring, a first rotating motor, a second rotating motor and a first clamping cylinder. The upper base is arranged on the frame, and the middle part of the upper base is vertically penetrated to form a cylindrical line hooking avoidance space connected to the bottom of the frame. The rotating ring is rotatably mounted on the side of the upper base and is coaxial with the line hooking avoidance space. The first rotating motor is arranged on the outer side below the upper base and is connected to the rotating ring to drive the rotating ring to rotate on the side of the upper base. The bottom end of the connecting frame is connected to the top surface of the rotating ring. The second rotating motor is horizontally arranged at the top of the connecting frame. The cylinder body of the first clamping cylinder is connected to the drive shaft of the second rotating motor, and the clamping part of the first clamping cylinder is directly above the line hooking avoidance space of the upper base.

[0046] In one embodiment, the wire pulling mechanism includes a deflection base, a deflection motor, a reciprocating base, a reciprocating motor and a wire pulling assembly. The deflection base is rotatably arranged on the frame and is located on one side of the upper base. The deflection motor is arranged below the frame and connected to the deflection base to drive the deflection base to rotate horizontally. The top surface of the deflection base extends upward to form a mounting vertical plate. The reciprocating motor and the reciprocating base are respectively arranged on two side surfaces of the mounting vertical plate. An eccentric block is provided on the side of the reciprocating base facing the mounting vertical plate. One end of the eccentric block is rotatably connected to the reciprocating base. The drive shaft of the reciprocating motor passes through the mounting vertical plate and is fixedly connected to the other end of the eccentric block. The wire pulling assembly is horizontally arranged on the reciprocating base, and the end of the wire pulling assembly facing the hook avoidance space is a hook-shaped wire pulling end.

[0047] In summary, the present invention has the following beneficial effects:

[0048] The present invention provides a variety of winding methods that can make stray capacitance smaller, thereby improving the bandwidth of the product, providing ideas for product development, and greatly improving the yield of the wire package and the appearance of the wire package. The present invention also proposes a winding machine that can realize these winding methods, which is conducive to improving production efficiency and production quality.

[0076] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0077] It is worth noting that the directional words such as "upper" and "lower" involved in this article are all relative to the perspective of the drawings. They are only for the convenience of description and cannot be understood as limitations on the technical solution.

[0078] The present invention proposes a new winding method, which can be applied to existing winding machines, as follows:

[0079] Clamp the annular base 4, select half or a quarter of the base 4, and use copper wire 5 to wind it to form a first copper wire layer;

[0080] In one-half of the substrate 4, when the area of ​​the first copper wire layer is larger than one-quarter, the midpoint of the first copper wire layer coincides with the midpoint of the one-half of the substrate 4, and the winding of the one-quarter of the substrate 4 is first completed by wrapping the unwound portion of one side of the copper wire 5 wrapped around the first copper wire layer. Then, the winding of the other quarter of the substrate 4 is completed by wrapping the unwound portion of the other side of the copper wire 5 wrapped around the first copper wire layer, thereby completing the winding of the one-half of the substrate 4. Similarly, a new copper wire 5 is selected and wrapped around the other half of the substrate 4. The number of layers of copper wire 5 wrapped around the substrate 4 is greater than or equal to two.

[0081] In a quarter of the substrate 4, when the area of ​​the first copper wire layer is smaller than a quarter, the unwound portion of one side of the copper wire 5 wound around the first copper wire layer is first used to complete the winding within the quarter of the substrate 4, and the unwound portion of the other side of the copper wire 5 wound around the first copper wire layer is wound around the adjacent quarter of the substrate 4 to form the first copper wire layer. Subsequently, the unwound portion of the copper wire 5 in the adjacent quarter of the substrate 4 is used to complete the winding within the quarter of the substrate 4, thereby achieving the winding of one-half of the substrate 4. Similarly, a new copper wire 5 is selected to be wound around the other half of the substrate 4, and the number of winding layers of the copper wire 5 on the substrate 4 is greater than or equal to two layers.

[0082] In the present invention, for the convenience of description, the copper wire layer refers to: the part formed by the copper wire 5 at the same level during the process of the copper wire 5 winding around the substrate 4. It is easy to understand that the layer of copper wire 5 directly in contact with the substrate 4 is the first copper wire layer, the layer of copper wire 5 in contact with and wrapping the first copper wire layer is the second copper wire layer, the layer of copper wire 5 in contact with and wrapping the second copper wire layer is the third copper wire layer, and so on. Figure 1-3 In the figure, only the cross section of the copper wire 5 inside the substrate 4 is shown. It is easy to understand that when the substrate 4 is wrapped, part of the copper wire 5 must be outside the substrate 4. For ease of understanding and explanation, the cross-sectional schematic diagram of the copper wire 5 outside the substrate 4 is omitted in the accompanying drawings of the present invention.

[0083] Specifically, the present invention includes four winding methods, combined with Figure 1-4 The details are as follows:

[0084] refer to Figure 1 Winding method 1: A1. Hold the annular substrate 4 and first wrap a section of copper wire 5 around the substrate 4. Use the winding position as the starting point. Select half of the substrate 4 and start from the starting point. Wrap the copper wire 5 around the substrate 4 in a clockwise or counterclockwise direction to form the first copper wire layer. Divide the half of the substrate 4 into two quarters at the midpoint of the first copper wire layer.

[0085] At this time, gaps are formed between adjacent copper wires in the first copper wire layer;

[0086] A2. Take the unwound copper wire 5 on one side of the quarter of the substrate 4 and wrap it once clockwise or counterclockwise in the gap formed by the adjacent copper wires 5 in the first copper wire layer to form the second copper wire layer.

[0087] A3. After completing step A2, wrap the wire once more within the second copper wire layer to form gaps between adjacent copper wires 5 within the second copper wire layer, and then wrap the wire once more around the gaps in the second copper wire layer to form a third copper wire layer.

[0088] A4. After completing step A3, if the number of copper wire layers required is three, return to the second copper wire layer and wind it once more to form new gaps between adjacent copper wires 5 in the second copper wire layer, and then wind it once more in the new gaps in the second copper wire layer;

[0089] Repeat step A4 until the winding of the second copper wire layer and the third copper wire layer is completed within the quarter portion of the substrate 4; then proceed to step A6;

[0090] A5. After completing step A3, when the required number of copper wire layers is greater than three, if there are unfilled gaps between adjacent copper wires 5 in the same layer, the next copper wire layer is wound around the unfilled gaps. When new gaps are formed in the next copper wire layer to fill the gaps, the newly formed gaps are filled first. This process continues until the required number of copper wire layers on the substrate 4 is reached or no new gaps are formed. Then, winding is resumed on the second copper wire layer.

[0091] Repeat step A5 until the copper wire 5 is wound around one quarter of the substrate 4; then proceed to step A6.

[0092] A6. Repeat steps A2-A5 in the opposite direction to step A2 to wind another quarter of the substrate 4 in step A2, thereby completing the winding of the copper wire 5 on the half of the substrate 4.

[0093] A7. Repeat steps A1 to A6, and use another section of copper wire 5 to wind around the other half of the substrate 4, thereby completing the winding of the copper wire 5 on the substrate 4.

[0094] by Figure 1 For example, in the lower half of the substrate 4, the copper wire 5 is first wrapped counterclockwise around the substrate 4 to form a first copper wire layer. Then, in the lower left quarter of the substrate 4, the unwound portion of the copper wire 5 outside the left side of the first copper wire layer is first wrapped clockwise once on the gap formed by adjacent copper wires in the first copper wire layer to form a second copper wire layer. Then, it is wrapped once again to form a gap between adjacent copper wires 5 in the second copper wire layer. The copper wire 5 is wrapped once on the gap to form a third copper wire layer. The copper wire 5 is then returned to the second copper wire layer and wrapped clockwise once to form a new gap between adjacent copper wires 5 in the second copper wire layer. The copper wire is wrapped once again on the new gap in the second copper wire layer. The above operation is repeated until the winding of the copper wire 5 in the lower left quarter of the substrate 4 is completed.

[0095] Similarly, in the lower right quarter of the substrate 4, first wrap it counterclockwise to form the second copper wire layer. Referring to the above steps, complete the winding of the copper wire 5 in the lower right quarter of the substrate 4, thereby completing the winding of the copper wire 5 in the lower half of the substrate 4.

[0096] A new section of copper wire 5 is used to wrap around the upper half of the base 4 in the same manner as above. The base 4 is entirely wrapped with three layers of copper wire 5.

[0097] refer to Figure 2Winding method 2: B1. Clamp the annular substrate 4 and first wrap a section of copper wire 5 around the substrate 4 once. Starting from the winding position of the copper wire 5 and the substrate 4, select half of the substrate 4 and wrap the copper wire 5 around the substrate 4 in a clockwise or counterclockwise direction to form the first copper wire layer. Divide the half of the substrate 4 into two quarters at the midpoint of the first copper wire layer.

[0098] B2. Take the unwound portion of copper wire 5 on one side of one quarter of the substrate 4 and wind it again on the first copper wire layer to form a second copper wire layer;

[0099] B3. When the number of copper wire layers required is greater than two, within one-quarter of the substrate 4, after the second copper wire layer is wound, a new unwound portion of copper wire 5 is formed outside the end of the second copper wire layer. The unwound portion of copper wire 5 of the second copper wire layer is wound again around the substrate 4 in a direction opposite to the winding direction of the second copper wire layer to form a third copper wire layer. Otherwise, the process proceeds directly to step B5.

[0100] B4. When the required number of copper wire layers is greater than three, continue winding the copper wire 5 in the manner of step B3 until the number of copper wire layers within one-quarter of the substrate 4 reaches the required number; otherwise, proceed directly to step B5;

[0101] B5. Repeat steps B2 to B4 to wind another quarter of the substrate 4 in step B2, thereby completing the winding of the copper wire 5 on the half of the substrate 4.

[0102] B6. Repeat steps B1 to B5, and use another section of copper wire 5 to wind around the other half of the substrate 4, thereby completing the winding of the copper wire 5 on the substrate 4.

[0103] It is easy to understand that the length of the newly wound copper wire layer is actually wound and positioned according to the gap formed by the adjacent copper wire 5 parts in the previously wound copper wire layer adjacent to it. Therefore, for one-half of the base 4, the total length of the copper wire layer of the same level is less than the total length of the adjacent previously wound copper wire layer. More specifically, for the purpose of illustration, the process of winding the second copper wire layer is used. When winding, the copper wire 5 of the second copper wire layer is actually wound and positioned according to the gap formed by the adjacent copper wire 5 parts in the first copper wire layer, thereby achieving the fixation of the second copper wire layer. Similarly, when winding the third copper wire layer, it is also wound and positioned according to the gap formed by the adjacent copper wire 5 parts in the second copper wire layer. And so on, the winding and positioning of more layers of copper wire 5 are achieved. The above rules are applicable to the following winding methods two and three, and will not be repeated below.

[0104] by Figure 2For example, in the lower half of the substrate 4, the copper wire 5 is first wrapped counterclockwise around the substrate 4 to form a first copper wire layer. Then, in the lower left quarter of the substrate 4, the unwound portion of the copper wire 5 outside the left side of the first copper wire layer is wrapped counterclockwise around the substrate 4 to form a second copper wire layer. A new unwound portion is formed outside the right end of the second copper wire layer, and the new unwound portion of the copper wire 5 is wrapped clockwise around the substrate 4 to form a third copper wire layer. Similarly, in the lower right quarter of the substrate 4, the unwound portion of the copper wire 5 outside the right side of the first copper wire layer is wrapped clockwise around the substrate 4 to form a second copper wire layer, until it approaches the second copper wire layer in the lower left quarter, a new unwound portion is formed outside the left end of the second copper wire layer, and the new unwound portion of the copper wire 5 is wrapped counterclockwise around the substrate 4 to form a third copper wire layer. In this way, the winding of the copper wire 5 in the lower half of the substrate 4 is completed, and a new section of copper wire 5 is used to wrap the upper half of the substrate 4 with reference to the above steps. The substrate 4 is wrapped with three layers of copper wire 5 as a whole.

[0105] refer to Figure 3 Winding method three: C1, clamp the ring-shaped base 4, first wrap the copper wire 5 around the base 4 once, take the winding position of the copper wire 5 and the base 4 as the starting point, select the half of the base 4, the starting point is at the center of the half of the base 4, and divide the half of the base 4 into two equal quarters;

[0106] C2. Starting from the starting point, in one quarter of the substrate 4, the copper wire 5 is first wound around the substrate 4 in a clockwise or counterclockwise direction to form a first copper wire layer, and an unwound portion is formed outside the end of the first copper wire layer away from the starting point;

[0107] C3, the unwound portion of the copper wire 5 outside the first copper wire layer is wound around the substrate 4 again in a direction opposite to the winding direction of the first copper wire layer to form a second copper wire layer, and an unwound portion is formed outside the second copper wire layer;

[0108] C4. When the number of copper wire layers required is greater than two, the unwound portion of the copper wire 5 outside the second copper wire layer is wound around the substrate 4 again in a direction opposite to the winding direction of the second copper wire layer to form a third copper wire layer; otherwise, the process proceeds directly to step C6;

[0109] C5. When the required number of copper wire layers is greater than three, continue winding the copper wire 5 in the manner of step C4 until the number of copper wire layers within one-quarter of the substrate 4 reaches the required number; otherwise, proceed directly to step C6.

[0110] C6. Wrap the copper wire 5 around the substrate 4 in the opposite direction to step C2 to form a first copper wire layer. Then repeat steps C3 to C5 to wrap the other quarter of the substrate 4 in step C2, thereby completing the wrapping of the copper wire 5 around one-half of the substrate 4.

[0111] C7. Repeat steps C1 to C6, and use another section of copper wire 5 to wind around the other half of the substrate 4, thereby completing the winding of the copper wire 5 on the substrate 4.

[0112] by Figure 3 For example, in the lower half of the substrate 4, the middle is used as the starting point for winding the copper wire 5. In the lower left quarter of the substrate 4, the copper wire 5 is first wound around the substrate 4 clockwise to form a first copper wire layer, and the unwound part of the copper wire 5 outside the left side of the first copper wire layer is wound around the substrate 4 counterclockwise to form a second copper wire layer. A new unwound part is formed outside the right end of the second copper wire layer, and the new unwound part of the copper wire 5 is used to wrap around the substrate 4 clockwise to form a third copper wire layer. Similarly, in the lower right quarter of the substrate 4, the copper wire 5 is first wound around the substrate 4 counterclockwise to form a first copper wire layer, and the unwound part of the copper wire 5 outside the right side of the first copper wire layer is wound around the substrate 4 clockwise to form a second copper wire layer. A new unwound part is formed outside the left end of the second copper wire layer, and the new unwound part of the copper wire 5 is used to wrap around the substrate 4 counterclockwise to form a third copper wire layer.

[0113] Thus, the copper wire 5 is wound around the lower half of the base 4. A new section of copper wire 5 is wound around the upper half of the base 4 by referring to the above steps. The base 4 is wound with three layers of copper wire 5 as a whole.

[0114] refer to Figure 4 Winding method four: D1, clamp the ring-shaped base 4, first wrap the copper wire 5 around the base 4 once, take the winding position of the copper wire 5 and the base 4 as the starting point, select the half of the base 4, the starting point is at the center of the half of the base 4, and divide the half of the base 4 into two equal quarters;

[0115] D2. Starting from the starting point, wrap the wire once clockwise or counterclockwise within one quarter of the substrate 4 to form the first copper wire layer. Then, form gaps between adjacent copper wires 5 within the first copper wire layer. Wrap the wire once more around the gaps to form the second copper wire layer.

[0116] D3. After completing step D2, if the number of copper wire layers required is two, return to the first copper wire layer and wind it once more, forming a new gap between adjacent copper wires 5 in the first copper wire layer, and wind it once more in the new gap. Repeat step D3 until the winding of the first and second copper wire layers is completed within one-quarter of the substrate 4; then proceed to step D5.

[0117] D4. After completing step D2, when the required number of copper wire layers is greater than two, if there are unfilled gaps between adjacent copper wires 5 in the same layer, the next copper wire layer is wound on the unfilled gaps. When new gaps are formed in the next copper wire layer to fill the gaps, the newly formed gaps are filled first. This process continues until the required number of copper wire layers on the substrate 4 is reached or no new gaps are formed. Then, winding is resumed on the first copper wire layer.

[0118] Repeat step D4 until the copper wire 5 is wound around one quarter of the substrate 4; then proceed to step D5;

[0119] D5. Wrap the copper wire 5 around the substrate 4 once in the opposite direction to step D2, then repeat steps D3-D4 to wrap the other quarter of the substrate 4 in step D2, thereby completing the wrapping of the copper wire 5 around one-half of the substrate 4;

[0120] D6. Repeat steps D1 to D5, and use another section of copper wire 5 to wind around the other half of the substrate 4, thereby completing the winding of the copper wire 5 on the substrate 4.

[0121] by Figure 4 For example, in the lower half of the substrate 4, with the middle as the starting point for winding the copper wire 5, in the lower left quarter of the substrate 4, it is first wound clockwise once to form a first copper wire layer, and a gap is formed between adjacent copper wire 5 parts in the first copper wire layer. Then it is wound once on the gap to form a second copper wire layer, and then it returns to the first copper wire layer and winds clockwise once to form a new gap between adjacent copper wire 5 parts in the first copper wire layer. It is wound once on the new gap in the first copper wire layer. At this time, a gap is also formed between adjacent copper wire 5 parts in the second copper wire layer. It is wound clockwise once on the gap in the second copper wire layer to form a third copper wire layer, and then it returns to the layer of the first copper wire layer to wind to create a new gap in the first copper wire layer. The above operation is repeated until the winding of the copper wire 5 in the lower left quarter of the substrate 4 is completed.

[0122] Similarly, in the lower right quarter of the substrate 4, first wrap it counterclockwise to form the first copper wire layer. Referring to the above steps, complete the winding of the copper wire 5 in the lower right quarter of the substrate 4, thereby completing the winding of the copper wire 5 in the lower half of the substrate 4.

[0123] A new section of copper wire 5 is used to wrap around the upper half of the base 4 in the same manner as above. The base 4 is entirely wrapped with three layers of copper wire 5.

[0124] It should be noted that the “clockwise” and “counterclockwise” mentioned in the four winding methods of the present invention are all based on the substrate 4 , rather than the copper wire itself.

[0125] In the present invention, the first winding method is a multi-segment winding method, the second winding method is an improvement on the cross winding method, the third winding method is another improvement on the cross winding method, and the fourth winding method is another multi-segment winding method. The winding methods of the present invention can reduce stray capacitance and thereby increase the product's bandwidth, with the first and fourth winding methods being particularly effective.

[0126] like Figure 15-18 As shown, the insulation resistance of the product formed by the second cross winding method of the present invention is lower, and the insulation resistance of the product formed by the first multi-segment winding method is even lower, and the product quality is higher.

[0127] like Figure 5-14 As shown, the present invention also proposes a winding machine that can be applied to the above-mentioned four different winding methods, specifically including a frame 1 and a winding module 2 and a wire feeding module 3 arranged on the frame 1. The winding machine can be used in conjunction with existing conventional loading devices, such as conventional vibration disk feeding devices, to feed the substrate 4 into the winding machine in an orderly manner. It is easy to understand that the winding machine is also used in conjunction with existing conventional transportation devices, such as multi-axis manipulators, two-way or three-way motion devices, to realize the transportation of the substrate 4 or semi-finished products in the winding machine and the unloading of products. This is not related to the content of the present invention and the present invention does not make specific restrictions.

[0128] A winding module 2 corresponds to a wire supply module 3, forming a winding station, which can complete the winding of the copper wire 5 on the half part of the substrate 4. It is easy to understand that in the winding machine, there can be two or more winding stations, which depends on the design requirements.

[0129] In the present invention, the substrate 4 can be a bare metal product or a metal product covered with an insulating material, and the copper wire 5 can be a bare copper wire 5 or an enameled wire with an insulated surface. As long as the contact surface between the substrate 4 and the copper wire 5 is insulated, the substrate 4 and the copper wire 5 of the present invention are both common materials in the field.

[0130] The winding module 2 includes a rotating clamping mechanism 21, a wire hooking mechanism 23, and a wire pulling mechanism 22. The base 4 is clamped and fixed by the rotating clamping mechanism 21, so that the base 4 is placed flat on the wire hooking mechanism 23, so that the hook 2303 of the wire hooking mechanism 23 can pass through the base 4 and pull the copper wire 5 down. The wire pulling mechanism 22 is located outside the base 4 and cooperates with the wire hooking mechanism 23 to realize the winding of the copper wire 5 on the base 4. The structure of the winding module 2 of the present invention is described in detail below:

[0131] The structure of the rotating clamping mechanism 21 is diverse, as long as it can clamp the base 4 and control the base 4 to rotate about the axis of the base 4. For example, the rotating clamping mechanism 21 can adopt the device for clamping the base 4 of the existing winding machine.

[0132] Preferably, the present invention proposes a feasible rotating clamping mechanism 21, such as Figure 4-5 As shown, the rotary clamping mechanism 21 includes an upper base 2101, a connecting frame 2105, a rotating ring 2103, a first rotating motor 2104, a second rotating motor 2106 and a first clamping claw cylinder 2107. The upper base 2101 is arranged on the frame 1. The middle part of the upper base 2101 is vertically penetrated to form a cylindrical hooking line avoidance space 2102 connected to the bottom of the frame 1. The rotating ring 2103 is rotatably sleeved on the side of the upper base 2101 and is coaxial with the hooking line avoidance space 2102. The first rotating motor 2104 is provided on the upper base 2101. 04 is arranged on the lower outer side of the upper base 2101 and is connected to the rotating ring 2103, driving the rotating ring 2103 to rotate on the side of the upper base 2101. The bottom end of the connecting frame 2105 is connected to the top surface of the rotating ring 2103. The second rotating motor 2106 is horizontally arranged on the top of the connecting frame 2105. The cylinder body of the first clamping claw cylinder 2107 is connected to the transmission shaft of the second rotating motor 2106, and the clamping claw portion of the first clamping claw cylinder 2107 is located directly above the line hooking avoidance space 2102 of the upper base 2101. It is easy to understand that when the first clamping claw cylinder 2107 clamps the base 4, the base 4 is directly above the line hooking avoidance space 2102, and the axis of the base 4 coincides with the axis of the line hooking avoidance space 2102.

[0133] The working principle of the rotating clamping mechanism 21 is: the first clamping claw cylinder 2107 clamps the base 4 so that the base 4 is placed horizontally just above the wire hooking avoidance space 2102; the first rotating motor 2104 drives the rotating ring 2103 to rotate, and through the connecting frame 2105, the first clamping claw cylinder 2107 rotates synchronously with the rotating ring 2103. Since the base 4 is coaxial with the rotating ring 2103 and the wire hooking avoidance space 2102, the base 4 actually rotates around its own axis. By controlling the rotation angle of the base 4 and cooperating with the wire hooking mechanism 23 and the wire pulling mechanism 22, the copper wire 5 can be wound regularly.

[0134] For the four winding methods described above, the first rotating motor 2104 and the second rotating motor 2106 cooperate to achieve orderly winding of the copper wire 5 on the substrate 4. For a winding machine with a single winding station, after completing the winding of the copper wire 5 around one-half of the substrate 4, the position of the semi-finished product is adjusted so that the unwound portion of the substrate 4 is ready for winding, and then a new copper wire 5 is used to wind the other half of the substrate 4. For a winding machine with two winding stations, after completing the winding of the copper wire 5 around one-half of the substrate 4, the semi-finished product is transported to the second winding station to wind the other half of the substrate 4.

[0135] Furthermore, the rotating clamping mechanism 21 also includes a protective cylinder 2108, which is arranged on the upper base 2101 and is located below the first clamping cylinder 2107. The protective cylinder 2108 is coaxial with the hook line avoidance space 2102, and the inner diameter of the protective cylinder 2108 is the same as the inner diameter of the hook line avoidance space 2102.

[0136] The structure of the wire hooking mechanism 23 is various, as long as it can realize the structure of pulling the copper wire 5 from the outside to the inside and from the top to the bottom. For example, the wire hooking mechanism 23 can adopt the wire hooking device of the existing winding machine.

[0137] Preferably, the present invention proposes a feasible hooking mechanism 23, such as Figure 9 As shown, the line hooking mechanism 23 includes a lower base, a screw elevator 2301, a connecting block 2302 and a hook 2303. The lower base is arranged below the frame 1, the screw elevator is fixedly connected to the lower base, and the connecting block 2302 is connected to the screw elevator 2301 to realize the vertical lifting of the connecting block 2302. The bottom end of the hook hook 2303 is fixedly connected to the connecting block 2302, and the hook hook 2303 is on the axis of the line hook avoidance space 2102. The top end of the hook hook 2303 is a line hook end in the shape of a fish hook.

[0138] The working principle of the wire hooking mechanism 23 is: when the copper wire 5 is placed horizontally above the base 4, the screw elevator 2301 drives the hook needle 2303 to rise, and the wire hooking end of the hook needle 2303 approaches the copper wire 5 and continues to rise until the wire hooking end is completely above the copper wire 5. Then the hook needle 2303 descends, and the copper wire 5 enters the wire hooking end and is pulled downward until the copper wire 5 is completely pulled through the inside of the base 4. At this time, the copper wire 5 passes through the base 4 vertically. With the cooperation of the wire pulling mechanism 22, the copper wire 5 is pulled from the inside to the outside and from the bottom to the top, and is placed horizontally above the base 4 again, thereby realizing one winding of the copper wire 5 on the base 4.

[0139] When the protective tube 2108 is provided, the portion of the copper wire 5 that is pulled down is inside the protective tube 2108 , which effectively prevents the copper wire 5 from deviating and facilitates the contact between the wire pulling mechanism 22 and the copper wire 5 .

[0140] The structure of the wire pulling mechanism 22 is various, as long as it can realize the structure of pulling the copper wire 5 from the inside to the outside and from the bottom to the top. For example, the wire pulling mechanism 22 can adopt the wire pulling device of the existing winding machine.

[0141] Preferably, the present invention proposes a feasible wire pulling mechanism 22, such as Figure 6-8As shown, the wire pulling mechanism 22 includes a deflection base 2201, a deflection motor 2202, a reciprocating base 2203, a reciprocating motor 2204 and a wire pulling assembly. The deflection base 2201 is rotatably arranged on the frame 1 and is located on one side of the upper base 2101. The deflection motor 2202 is arranged below the frame 1 and is connected to the deflection base 2201 to drive the deflection base 2201 to rotate horizontally. The top surface of the deflection base 2201 extends upward to form a mounting vertical plate 2207. The reciprocating motor 2204 and the reciprocating base 2204 are connected to the deflection base 2201. The seat 2203 is respectively arranged on the two side surfaces of the mounting vertical plate 2207, and an eccentric block 2206 is arranged on the side of the reciprocating base 2203 facing the mounting vertical plate 2207. One end of the eccentric block 2206 is rotatably connected to the reciprocating base 2203, and the transmission shaft of the reciprocating motor 2204 passes through the mounting vertical plate 2207 and is fixedly connected to the other end of the eccentric block 2206. The wire pulling assembly is horizontally arranged on the reciprocating base 2203, and the end of the wire pulling assembly facing the hook wire avoidance space 2102 is a hook-shaped wire pulling end.

[0142] It is easy to understand that when the wire pulling assembly is extended forward to the limit position, the wire pulling end exceeds the axis of the base 4. The working principle of the wire pulling assembly includes two steps: pulling out the copper wire 5 and resetting the copper wire 5, which are as follows:

[0143] Since the reciprocating motor 2204 and the reciprocating base 2203 are connected by an eccentric piece, the movement trajectory of the wire pulling assembly includes four trajectories that are performed in sequence based on the wire pulling assembly. The first trajectory is: the wire pulling assembly extends forward to the extreme position. At this time, the wire pulling assembly is below the base 4, and the wire pulling end exceeds the axis of the base 4, so that the copper wire 5 in the middle of the base 4 is inside the wire pulling end; the second trajectory is: the wire pulling assembly retracts backward to the extreme position. During this process, the copper wire 5 is below the base 4 and close to the base 4 and is pulled out of the base 4; the third trajectory is: the wire pulling assembly extends forward to the extreme position. At this time, the wire pulling assembly is above the base 4. During this process, the part of the copper wire 5 that is pulled out surrounds the wire pulling end and is brought above the base 4. This part of the copper wire 5 is placed horizontally above the base 4, waiting for the wire hooking assembly to hook all the copper wire 5 that is not wrapped around the base 4 into the base 4; the fourth trajectory is: the wire pulling assembly retracts backward to the extreme position. It is easy to understand that after the wire pulling assembly completes the first and second sections of the track, it completes the step of pulling out the copper wire 5, and after completing the third and fourth sections of the track, it completes the step of resetting the copper wire 5.

[0144] In the first section of the trajectory, before the wire pulling assembly is ready to extend forward, the deflection motor 2202 first controls the deflection base 2201 to rotate an angle, so that the wire pulling end of the wire pulling assembly rotates in the direction away from the copper wire 5. When the wire pulling assembly moves forward to the extreme position, the deflection motor 2202 controls the deflection base 2201 to rotate in the opposite direction by the same angle, so that the copper wire 5 is inside the wire pulling end, avoiding the situation where the copper wire 5 is not pulled in the second section of the trajectory.

[0145] In the third trajectory, after the wire pulling assembly has moved forward to its limit position, the deflection motor 2202 controls the deflection base 2201 to rotate an angle, causing the wire pulling end of the wire pulling assembly to rotate away from the copper wire 5. At this time, the wire pulling end moves the copper wire 5 in a direction away from the axis of the hook 2303, which is equivalent to the copper wire 5 avoiding the hook end of the hook 2303 during the hook 2303's ascent. After the hook 2303 rises to its limit position, the deflection motor 2202 controls the deflection base 2201 to rotate in the opposite direction by the same angle, bringing the copper wire 5 to a position where the hook end can hook the copper wire 5 when the hook 2303 descends. The hook 2303 then descends, pulling the copper wire 5 downward. After passing the fourth trajectory, the wire pulling assembly resets and waits for the next cycle. That is, the first to fourth trajectories are regarded as one cycle, and the cycle is repeated multiple times. With the cooperation of the hook mechanism 23 and the rotating clamping mechanism 21, the copper wire 5 is wound on the base 4 in an orderly manner as required. It is easy to understand that the hook 2303 pulls the copper wire 5 downward, so that all the remaining unwound copper wire 5 are pulled under the base 4, which is similar to the function of the wire hook component in the prior art. There will be no situation where the end of the copper wire 5 does not pass through the base 4, causing the wire pulling component to pull two or even multiple sections of copper wire 5 at the same time.

[0146] It is easy to understand that since there is a need for the crochet hook 2303 to rise and pass through the wire pulling end in the third trajectory, the space inside the wire pulling end is larger, which is convenient for the crochet hook 2303 to pass through.

[0147] Furthermore, the wire pulling assembly includes a wire pulling member 2205 and a guide member 2208. As shown in the figure, the wire pulling member 2205 is horizontally arranged, and one end of the wire pulling member 2205 is connected to the top surface of the reciprocating base 2203, and the other end of the wire pulling member 2205 is facing the base 4, and a avoidance position 2209 is formed at the end. The guide member 2208 is arranged at the end of the wire pulling member 2205 facing the base 4. The guide member 2208 is in the avoidance position 2209, so that the end of the wire pulling member 2205 forms a hook-like structure. An annular wire groove 2217 is provided on the side of the guide member 2208. When driving the copper wire 5, the copper wire 5 enters the wire groove 2217. The wire groove 2217 has a limiting effect on the copper wire 5. When the wire pulling assembly is horizontally deflected, the wire groove 2217 will drive the copper wire 5 to move together to prevent the copper wire 5 from falling out.

[0148] Furthermore, the wire pulling assembly also includes a deflection limiting assembly and a reciprocating limiting assembly.

[0149] The deflection limit assembly includes a first proximity switch 2210 and a first detection piece 2211. The first proximity switch 2210 is arranged on the frame 1 and is located on one side of the deflection base 2201. The first detection piece 2211 is arranged on the side of the deflection base 2201 close to the first proximity switch 2210. The first proximity switch 2210 continues to detect the first detection piece 2211. When the deflection base 2201 rotates and the first proximity switch 2210 cannot detect the first detection piece 2211, it means that the deflection angle is too large, that is, when the deflection base 2201 moves normally, the first proximity switch 2210 can always detect the signal of the first detection piece 2211.

[0150] The reciprocating limit assembly includes a second proximity switch 2212 and a second detection piece 2213. The second proximity switch 2212 is disposed on the deflection base 2201, near the bottom surface of the reciprocating base 2203. The second detection piece 2213 is disposed on the bottom surface of the reciprocating base 2203, facing the second proximity switch 2212. The function of the reciprocating limit assembly is to determine whether the reciprocating base 2203 has descended into place.

[0151] Furthermore, the wire pulling mechanism 22 also includes a guide assembly, which is arranged on the side of the mounting riser 2207 facing the reciprocating base 2203. The guide assembly includes a transverse guide rail 2216, a guide plate 2215, and a vertical guide rail 2214. The transverse guide rail 2216 is fixedly arranged on the side of the mounting riser 2207. The side of the guide plate 2215 facing the mounting riser 2207 is slidably connected to the transverse guide rail 2216 via a transverse guide portion. The vertical guide rail 2214 is vertically arranged on the side of the guide plate 2215 facing the reciprocating base 2203. The side of the reciprocating base 2203 facing the mounting riser 2207 is slidably connected to the vertical guide rail 2214 via a vertical guide portion. The rotation of the reciprocating base 2203 is decomposed into transverse movement and vertical movement of the reciprocating base 2203 on the guide assembly. The guide assembly helps to improve the stability of the movement of the reciprocating base 2203.

[0152] Furthermore, the winding module 2 also includes a limiting mechanism 24, such as Figure 10As shown, the limiting mechanism 24 includes a fixed seat 2401, a second clamping cylinder 2402 and two limiting plates 2403. The fixed seat 2401 is set between the deflection base 2201 and the upper base 2101. The second clamping cylinder 2402 is set on the fixed seat 2401. The two limiting plates 2403 are connected to the second clamping cylinder 2402. The second clamping cylinder 2402 controls the synchronous approach or distance. The limiting plates 2403 A copper wire 5 avoidance position 2404 is set on one side facing the other limiting piece 2403. The copper wire 5 avoidance position 2404 is above the hook wire avoidance space 2102 and below the wire pulling piece 2205. When the two limiting pieces 2403 are close to each other, the two copper wire 5 avoidance positions 2404 form a hook wire avoidance hole. The hook wire avoidance hole is coaxial with the hook wire avoidance space 2102, and the inner diameter of the hook wire avoidance hole is larger than the outer diameter of the crochet hook 2303.

[0153] It is easy to understand, as shown in the accompanying drawings, that when the upper base 2101 is provided with a protective tube 2108 , the two limiting pieces 2403 are both located above the protective tube 2108 .

[0154] The limiting mechanism 24 is used in conjunction with the winding of the copper wire 5. When the wire feeding mechanism outputs the copper wire 5, the two limiting plates 2403 are in a state of being separated from each other. Before the operation of winding the copper wire 5 begins, the two limiting plates 2403 are in a state of being close to each other, so that the copper wire 5 is in a state of passing through the wire hook avoidance hole. During the subsequent winding operation, the two limiting plates 2403 remain in a state of being close to each other. When the wire hooking mechanism 23 pulls the copper wire 5 downward, the copper wire 5 can only pass through the wire hook avoidance hole. In other words, the limiting mechanism 24 ensures that the copper wire 5 always remains in a relatively vertical state after being pulled down, effectively preventing the copper wire 5 from shifting.

[0155] It should be noted that, similar to the existing winding operation, during the winding process, after the wire feeding module 3 stops feeding the copper wire 5, the copper wire 5 is not cut off first, which is equivalent to the wire feeding module 3 fixing the top of the copper wire 5, and the wire hooking mechanism 23 and the wire pulling mechanism 22 are used to wind the remaining portion of the copper wire 5. After the portion of the copper wire 5 near the bottom is wound, the wire feeding module 3 cuts the copper wire 5, and the wire hooking mechanism 23 and the wire pulling mechanism 22 then wind the portion of the copper wire 5 near the top. The above process is a conventional operation in this field and will not be repeated in the present invention.

[0156] In the present invention, the wire feeding module 3 can be a common wire feeding device in the field, as long as it can realize the wire feeding operation required by the winding machine. Preferably, the present invention proposes a feasible wire feeding module 3, such as Figure 11-13As shown, the wire feeding module 3 includes a wire feeding base plate 31, a connecting seat 32, a wire feeding rotating motor 33 and a wire feeding assembly 34. The wire feeding assembly 34 is arranged on the wire feeding base plate 31. A connecting rod 35 is arranged on the bottom surface of the wire feeding base. The connecting rod 35 is rotatably connected to the connecting seat 32. The wire feeding rotating motor 33 is arranged on the frame 1, and the transmission shaft passes through the connecting seat 32 and is fixedly connected to the connecting rod 35 to control the rotation of the wire feeding assembly 34.

[0157] The wire feeding assembly 34 includes a wire feeding guide wheel 3401, a wire feeding motor 3402, a wire feeding wheel 3403, a clamping cylinder 3404, a rotating frame 3407, a clamping wheel 3408, a cutter 3405 and a wire feeding tube 3406. As shown in the figure, the wire feeding guide wheel 3401 is arranged at the rear of the wire feeding substrate 31, the wire feeding wheel 3403 is horizontally and rotatably arranged above the wire feeding substrate 31, the wire feeding motor 3402 is arranged below the wire feeding substrate 31, and the transmission shaft of the wire feeding motor 3402 is connected to the wire feeding wheel 3403 in a transmission manner, the rotating frame 3407 is arranged on the wire feeding substrate 31, and is located on one side of the wire feeding wheel 3403. One side of the rotating frame 3407 is rotatably connected to the wire feeding substrate 31, and the other side of the rotating frame remains free. State, the pinch wheel 3408 is horizontally and rotatably arranged in the rotating frame 3407, and the pinch wheel 3408 is close to the wire feeding wheel 3403, the copper wire 5 is between the pinch wheel 3408 and the wire feeding wheel 3403, the pinch cylinder 3404 is arranged on the side of the rotating frame 3407 away from the wire feeding wheel 3403, the piston rod of the pinch cylinder 3404 is close to the other side of the rotating part that is not connected to the wire supply substrate 31, so as to drive the rotating frame 3407 to move toward the wire feeding wheel 3403 to compress the copper wire 5, the wire feeding tube 3406 is arranged in front of the wire feeding wheel 3403, and the front end of the wire feeding tube 3406 is bent downward toward the base 4, and the cutter 3405 is between the wire feeding tube 3406 and the wire feeding wheel 3403 to cut the copper wire 5.

[0158] The working principle of the wire feeding module 3 is as follows: first, the copper wire 5 is passed along the guide wheel through the pinch wheel 3408 and the wire feeding wheel 3403, and then into the wire feeding tube 3406. When the copper wire 5 needs to be conveyed, the piston rod of the pinch cylinder 3404 extends, pushing the rotating frame 3407 toward the wire feeding wheel 3403, causing the pinch wheel 3408 to apply pressure toward the wire feeding wheel 3403, tightly clamping the copper wire 5 between the pinch wheel 3408 and the wire feeding wheel 3403. Then, the wire feeding motor 3402 drives the wire feeding wheel 3403 to rotate, and the copper wire 5 is conveyed forward by friction. The length of the conveyed copper wire 5 can be obtained based on the circumference of the circular cross-section of the wire feeding wheel 3403 and the number of revolutions.

[0159] Before conveying the copper wire 5, the front end of the wire feeding tube 3406 is aligned with the middle of the base 4, and the copper wire 5 passes through the middle of the base 4. After the length of the conveyed copper wire 5 reaches the set value, the wire feeding wheel 3403 stops rotating, and the wire feeding wheel 3403 and the pressure wheel 3408 still keep the copper wire 5 clamped. Then the wire feeding rotating motor 33 drives the wire feeding assembly 34 to deflect an angle as a whole, so that the front end of the wire feeding tube 3406 is staggered with the base 4, which is convenient for subsequent winding operations. When it is necessary to cut the copper wire 5, the cutter 3405 is started to cut the copper wire 5. The copper wire 5 in the front is continued to be wound and used, and the copper wire 5 between the pressure wheel 3408 and the wire feeding wheel 3403 at the rear remains in a compressed state, waiting for the next wire feeding.

[0160] It is easy to understand that the wire feeding motor 3402 is provided with a feasible sensor such as an encoder to detect the number of revolutions of the wire feeding wheel 3403 .

[0161] The structure of the cutter 3405 is diverse. In the present invention, the cutter 3405 includes a baffle, a cutter, and a cutting cylinder. The baffle and the cylinder body of the cutting cylinder are fixedly mounted on the wire feeding base plate. The cutter is mounted on the piston rod of the cutting cylinder, and the cutter faces the baffle. The copper wire 5 is located between the cutter and the baffle.

[0162] In the present invention, the winding machine further comprises a control module, which is an electrical control device connected to the other modules to achieve orderly operation of the modules. The control module of the present invention is an existing conventional electrical control device and will not be described in detail in the present invention.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
