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 is composed of a substrate and a copper wire, and is insulated at the contact surface between the substrate and the copper wire. At present, the production of inductor coils is generally achieved by a winding machine, which winds the copper wire on the substrate according to a set winding method. The existing winding method is very simple and has few improvements. 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 deficiencies in the prior art, the purpose of the present invention is to provide a winding method and a winding machine, provide a variety of 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 a 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 the one half of the substrate, and the winding in one quarter of the substrate is first completed with the unwound portion on one side of the copper wire wound around the first copper wire layer, and then the winding in another quarter of the substrate is completed with the unwound portion on the other side of the copper wire wound around the first copper wire layer, thereby completing the winding of the one half of the substrate; similarly, new copper wires are selected to wind 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;

[0008] In a quarter of the substrate, when the area of ​​the first copper wire layer is smaller than a quarter, the unwound portion of 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 of the other side of the copper wire wound around the first copper wire layer is wound in an adjacent quarter of the substrate to form the first copper wire layer, and then 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 achieving the winding of one-half of the substrate; similarly, a new copper wire is selected to wind 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 comprises the following steps:

[0010] A1. Clamp the annular substrate, first wrap a section of copper wire around the substrate with the winding position as the starting point, select half of the substrate, and start from the starting point, wrap the copper wire around the substrate clockwise or counterclockwise to form the first copper wire layer, and divide the half of the substrate into two quarters with 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, winding once more in the second copper wire layer to form gaps between adjacent copper wire parts in the second copper wire layer, and then winding once more on the gaps in the second copper wire layer to form a third copper wire layer;

[0014] A4. After completing step A3, when the number of copper wire layers required is three, return to the second copper wire layer and wind it once, so that a new gap is formed between adjacent copper wire parts in the second copper wire layer, and then wind it once on the new gap in the second copper wire layer;

[0015] Repeat step A4 until the winding of the second copper wire layer and the third copper wire layer is completed in the quarter of the substrate; then proceed to step A6;

[0016] A5. After completing step A3, when the number of copper wire layers required is greater than three, when there are unfilled gaps between adjacent copper wires of the same layer, the next copper wire layer is wound on the unfilled gaps, and when new gaps are formed in the next copper wire layer to fill the gaps, the newly formed gaps are filled first, until the number of copper wire layers on the substrate reaches the requirement or no new gaps are formed, and then the winding is returned to the second copper wire layer again;

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

[0018] A6, repeating steps A2-A5 in the opposite direction to step A2, winding another 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 wind 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 comprises the following steps:

Clamp the annular substrate, first wrap a section of copper wire around the substrate once, take the winding position of the copper wire and the substrate as the starting point, select half of the substrate, and start from the starting point, wrap the copper wire around the substrate clockwise or counterclockwise to form the first copper wire layer, and divide the half of the substrate into two quarters with 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 wind 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, in one quarter of the substrate, after the winding of the second copper wire layer is completed, a new unwound portion of copper wire is formed outside the end of the second copper wire layer, and the unwound portion of the copper wire 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, directly proceed to step B5;

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

[0025] B5, repeating steps B2 to B4, winding another 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, and use another section of copper wire to wind 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 comprises the following steps:

[0028] C1. Clamp the annular substrate, first wrap the copper wire around the substrate once, take the winding position of the copper wire and the substrate as the starting point, select one half of the substrate, the starting point is at the center of the one half of the substrate, and divide the one half of the substrate 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 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, directly proceed to step C6;

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

[0033] C6, winding the copper wire around the substrate in the opposite direction to step C2 to form a first copper wire layer, then repeating steps C3 to C5 to wind another quarter of the substrate in step C2, thereby completing the winding of the copper wire around one-half of the substrate;

[0034] C7. Repeat steps C1 to C6, and use another section of copper wire to wind 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 comprises the following steps:

Clamp the annular substrate, first wrap the copper wire around the substrate once, take the winding position of the copper wire and the substrate as the starting point, select one half of the substrate, the starting point is at the center of the one half of the substrate, and divide the one half of the substrate into two equal quarters;

[0037] D2. Starting from the starting point, winding once clockwise or counterclockwise in one quarter of the substrate to form the first copper wire layer, forming a gap between adjacent copper wire parts in the first copper wire layer, and then winding once on the gap to form the second copper wire layer;

[0038] D3, after completing step D2, when the number of copper wire layers required is two, return to the first copper wire layer and wind it once, form a new gap between adjacent copper wire parts in the first copper wire layer, wind it once again on the new gap, and repeat step D3 until the winding of the first copper wire layer and the second copper wire layer is completed in one quarter of the substrate; then proceed to step D5;

[0039] D4. After completing step D2, when the number of copper wire layers required is greater than two layers, when there is an unfilled gap between adjacent copper wires of the same layer, the next copper wire layer is wound on the unfilled gap, and when a new gap is formed in the next copper wire layer to fill the gap, the newly formed gap is filled first, until the number of copper wire layers on the substrate reaches the requirement or no new gap is formed, and then the first copper wire layer is returned to be wound again;

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

[0041] D5, wrapping the copper wire around the substrate once in the opposite direction to step D2, and then repeating steps D3-D4 to wrap another quarter of the substrate in step D2, thereby completing the winding of the copper wire around one-half of the substrate;

[0042] D6. Repeat steps D1 to D5, and use another section of copper wire to wind 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, wherein 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 the copper wire down. The wire pulling mechanism is located outside 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 jaw cylinder. The upper base is arranged on the frame, and the middle part of the upper base is vertically penetrated to form a cylindrical wire hook 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 wire hook 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 jaw cylinder is connected to the transmission shaft of the second rotating motor, and the clamping jaw part of the first clamping jaw cylinder is directly above the wire hook avoidance space of the upper base.

[0046] In one of the embodiments, 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 arranged on a side of the reciprocating base facing the mounting vertical plate. One end of the eccentric block is rotatably connected to the reciprocating base. The transmission 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 wire avoidance space is a hook-shaped wire pulling end.

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

[0076] The present invention is described in detail below in conjunction with 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 viewing angle of the drawings and 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 substrate 4, select one half or one quarter of the substrate 4, and use the 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 in one quarter of the substrate 4 is first completed by winding the unwound portion of one side of the copper wire 5 wound around the first copper wire layer, and then the winding in another quarter of the substrate 4 is completed by winding the unwound portion of the other side of the copper wire 5 wound 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 to wind the other half of the substrate 4, and the number of winding layers of the copper wire 5 of the substrate 4 is greater than or equal to two layers;

[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 in an adjacent quarter of the substrate 4 to form a first copper wire layer, and then 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 wind the other half of the substrate 4, and the number of winding layers of the copper wire 5 of 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 a layer of copper wire 5 directly in contact with the substrate 4 is the first copper wire layer, a layer of copper wire 5 in contact with and wrapping the first copper wire layer is the second copper wire layer, a 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 wound, part of the copper wire 5 must be outside the substrate 4. For ease of understanding and explanation, the drawings of the present invention omit the schematic cross-sectional diagram of the copper wire 5 outside the substrate 4.

[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, clamp the annular substrate 4, first wrap a section of copper wire 5 around the substrate 4 with the winding position as the starting point, select one-half of the substrate 4, and start from the starting point, the copper wire 5 is first wound around the substrate 4 clockwise or counterclockwise to form a first copper wire layer, and the one-half of the substrate 4 is divided 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 one quarter of the substrate 4 and wind it once clockwise or counterclockwise on 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, winding once more in the second copper wire layer to form gaps between adjacent copper wires 5 in the second copper wire layer, and then winding once more on the gaps in the second copper wire layer to form a third copper wire layer;

[0088] A4. After completing step A3, when the number of copper wire layers required is three, return to the second copper wire layer and wind it once, so that a new gap is formed between adjacent copper wires 5 in the second copper wire layer, and then wind it once on the new gap 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 in the quarter of the substrate 4; then proceed to step A6;

[0090] A5. After completing step A3, when the number of copper wire layers required is greater than three layers, when there is an unfilled gap between adjacent copper wires 5 of the same layer, the next copper wire layer is wound on the unfilled gap, and when a new gap is formed in the next copper wire layer to fill the gap, the newly formed gap is filled first, until the number of copper wire layers on the substrate 4 reaches the requirement or no new gap is formed, and then the winding is returned to the second copper wire layer again;

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

[0092] A6, repeating steps A2-A5 in the opposite direction to step A2, winding 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 wound counterclockwise around the substrate 4 to form a first copper wire layer, and 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 wound clockwise once on the gap formed by adjacent copper wires in the first copper wire layer to form a second copper wire layer, and then wound once again to form a gap between adjacent copper wire 5 portions in the second copper wire layer, and wound once on the gap to form a third copper wire layer, and then returned to the second copper wire layer and wound once clockwise to form a new gap between adjacent copper wire 5 portions in the second copper wire layer, and wound once again on the new gap in the second copper wire layer, and repeated the above operation 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, and refer to the above steps to 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 the upper half of the substrate 4 according to the above steps. The substrate 4 is wrapped with three layers of copper wire 5 as a whole.

[0097] refer to Figure 2, Winding method 2: B1, clamp the annular substrate 4, first wrap a section of copper wire 5 around the substrate 4 once, take the winding position of the copper wire 5 and the substrate 4 as the starting point, select half of the substrate 4, start from the starting point, wrap the copper wire 5 around the substrate 4 clockwise or counterclockwise to form a first copper wire layer, and divide the half of the substrate 4 into two quarters at the midpoint of the first copper wire layer;

[0098] B2. Take the unwound 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, in one quarter of the substrate 4, after the winding of the second copper wire layer is completed, a new unwound portion of copper wire 5 is formed outside the end of the second copper wire layer, and the unwound portion of copper wire 5 of 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 directly proceeds to step B5;

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

[0101] B5, repeating steps B2 to B4, winding 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 substrate 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 fixing 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, to achieve the winding and positioning of more layers of copper wire 5. 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 firstly wound counterclockwise around the substrate 4 to form a first copper wire layer, and 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 wound 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 wound 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 wound 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 wound counterclockwise around the substrate 4 to form a third copper wire layer, thereby completing the winding of the copper wire 5 in the lower half of the substrate 4, and a new section of copper wire 5 is used to wind the upper half of the substrate 4 with reference to the above steps, and the substrate 4 is wound with three layers of copper wire 5 as a whole.

[0105] refer to Figure 3 , Winding method three: C1, clamp the annular substrate 4, first wrap the copper wire 5 around the substrate 4 once, take the winding position of the copper wire 5 and the substrate 4 as the starting point, select one half of the substrate 4, the starting point is at the center of the one half of the substrate 4, and divide the one half of the substrate 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 clockwise or counterclockwise 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 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 directly proceeds to step C6;

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

[0110] C6, winding the copper wire 5 around the substrate 4 in the opposite direction to step C2 to form a first copper wire layer, and then repeating steps C3 to C5 to wind another quarter of the substrate 4 in step C2, thereby completing the winding of the copper wire 5 on the 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 taken as the starting point for winding the copper wire 5, and in the lower left quarter of the substrate 4, the copper wire 5 is firstly wound around the substrate 4 clockwise to form a first copper wire layer, and the unwound portion 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 portion is formed outside the right end of the second copper wire layer, and the new unwound portion of the copper wire 5 is wound 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 firstly wound around the substrate 4 counterclockwise to form a first copper wire layer, and the unwound portion 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 portion is formed outside the left end of the second copper wire layer, and the new unwound portion of the copper wire 5 is wound around the substrate 4 counterclockwise to form a third copper wire layer.

[0113] Thus, the copper wire 5 is wound in the lower half of the substrate 4, and a new section of copper wire 5 is used to wind the upper half of the substrate 4 according to the above steps. The substrate 4 is wound with three layers of copper wire 5 as a whole.

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

[0115] D2, starting from the starting point, winding once clockwise or counterclockwise in one quarter of the substrate 4 to form a first copper wire layer, forming a gap between adjacent copper wires 5 in the first copper wire layer, and then winding once on the gap to form a second copper wire layer;

[0116] D3, after completing step D2, when the number of copper wire layers required is two, return to the first copper wire layer and wind it once, form a new gap between adjacent copper wires 5 in the first copper wire layer, wind it once again on the new gap, repeat step D3 until the winding of the first copper wire layer and the second copper wire layer is completed in one quarter of the substrate 4; then proceed to step D5;

[0117] D4, after completing step D2, when the number of copper wire layers required is greater than two layers, when there is an unfilled gap between adjacent copper wires 5 in the same layer, the next copper wire layer is wound on the unfilled gap, and when a new gap is formed in the next copper wire layer to fill the gap, the newly formed gap is filled first, until the number of copper wire layers on the substrate 4 reaches the requirement or no new gap is formed, and then the winding is returned to the first copper wire layer again;

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

[0119] D5, wrap the copper wire 5 around the substrate 4 once in the opposite direction to step D2, and then repeat steps D3-D4 to wrap another quarter of the substrate 4 in step D2, thereby completing the winding 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, first wind it clockwise once to form a first copper wire layer, form a gap between adjacent copper wire 5 parts in the first copper wire layer, then wind it once on the gap to form a second copper wire layer, then return to the first copper wire layer and wind it clockwise once to form a new gap between adjacent copper wire 5 parts in the first copper wire layer, wind it 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, wind it clockwise once on the gap in the second copper wire layer to form a third copper wire layer, then return to the layer of the first copper wire layer to wind to form a new gap in the first copper wire layer, and repeat the above operation 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, it is first wound counterclockwise to form the first copper wire layer. Referring to the above steps, the winding of the copper wire 5 in the lower right quarter of the substrate 4 is completed, 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 the upper half of the substrate 4 according to the above steps. The substrate 4 is wrapped with three layers of copper wire 5 as a whole.

[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 improved method of the cross winding method, the third winding method is another improved method of the cross winding method, and the fourth winding method is another multi-segment winding method. The winding method of the present invention can make the stray capacitance smaller, thereby improving the bandwidth of the product, especially the first and fourth winding methods have better effects.

[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 lower, and the product quality is higher.

[0127] like Figure 5-14 As shown, the present invention further proposes a winding machine, which can be applicable to the above-mentioned four different winding methods, specifically including a frame 1 and a wire supply module 2 and a wire supply module 3 arranged on the frame 1. The winding machine can be used in conjunction with an existing conventional loading device, such as a conventional vibration disk feeding device, 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 an existing conventional transportation device, such as a multi-axis manipulator, a two-way or three-way motion device, to realize the transportation of the substrate 4 or semi-finished product in the winding machine and the unloading of the product, which is irrelevant to the content of the present invention and the present invention does not make specific restrictions.

[0128] One wire supply module 2 corresponds to one wire supply module 3 respectively, 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 wire supply 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 needle 2303 of the wire hooking mechanism 23 passes through the base 4 to pull down the copper wire 5. 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 wire supply module 2 of the present invention is specifically described below:

[0131] The structure of the rotating clamping mechanism 21 is various, as long as it can realize the structure of clamping the base body 4 and controlling the base body 4 to rotate about the axis of the base body 4. For example, the rotating clamping mechanism 21 can adopt the device for clamping the base body 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 rotating 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 hook wire 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 hook wire avoidance space 2102. The first rotating motor 2104 is coaxial with the first rotating motor 2106. 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 jaw cylinder 2107 is connected to the transmission shaft of the second rotating motor 2106, and the clamping jaw of the first clamping jaw cylinder 2107 is located directly above the hooking wire avoidance space 2102 of the upper base 2101. It is easy to understand that when the first clamping jaw cylinder 2107 clamps the base 4, the base 4 is located directly above the hooking wire avoidance space 2102, and the axis of the base 4 coincides with the axis of the hooking wire 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 horizontally placed directly 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 regularly wound.

[0134] For the above four winding methods, the first rotating motor 2104 and the second rotating motor 2106 cooperate to realize the orderly winding of the copper wire 5 on the substrate 4. For a winding machine with a single winding station, after the copper wire 5 is wound around one-half of the substrate 4, the position of the semi-finished product is adjusted so that the unwound part of the substrate 4 is in a state to be wound, 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 the copper wire 5 is wound 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 tube 2108, which is arranged on the upper base 2101 and is located below the first clamping jaw cylinder 2107. The protective tube 2108 is coaxial with the hook line avoidance space 2102, and the inner diameter of the protective tube 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 Fig. 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, 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 2303 is fixedly connected to the connecting block 2302, and the hook 2303 is on the axis of the line hooking avoidance space 2102, and the top end of the hook 2303 is a line hooking 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 substrate 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 substrate 4. At this time, the copper wire 5 vertically passes through the substrate 4. 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 substrate 4 again, thereby realizing one winding of the copper wire 5 on the substrate 4.

[0139] When the protective tube 2108 is provided, the portion of the copper wire 5 that is pulled down is in 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 upper base 2101. The seats 2203 are 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. 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 of 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, with the wire pulling assembly as a reference, the movement trajectory of the wire pulling assembly includes four trajectories that are performed in sequence. The first trajectory is: the wire pulling assembly extends forward to the extreme position, at which 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 which 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 which time the wire pulling assembly is above the base 4, during which the part of the copper wire 5 that is pulled out surrounds the wire pulling end and is brought above the base 4, and 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 trajectory, the step of pulling out the copper wire 5 is completed, and after completing the third and fourth sections of the trajectory, the step of resetting the copper wire 5 is completed.

[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, thereby avoiding the situation where the copper wire 5 is not pulled in the second section of the trajectory.

[0145] In the third track, when the wire pulling assembly has moved forward to the limit position, the deflection motor 2202 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. At this time, the wire pulling end moves the copper wire 5 in the direction away from the axis of the hook needle 2303, which is equivalent to the copper wire 5 avoiding the hook end of the hook needle 2303 during the rising process of the hook needle 2303. After the hook needle 2303 rises to the 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 the position where the hook end can hook the copper wire 5 when the hook needle 2303 descends, and then the hook needle 2303 descends to pull the copper wire 5 downward. After the fourth track, the wire pulling assembly resets and waits for the next cycle, that is, the first to fourth tracks are regarded as one cycle, and the cycle is repeated for 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 needle 2303 pulls the copper wire 5 downward, so that the remaining unwound copper wire 5 is all pulled under the base 4, which is similar to the function of the wire hook assembly 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 assembly to pull two or even more sections of the copper wire 5 at the same time.

[0146] It is easy to understand that, since there is a need for the hook 2303 to rise and pass through the wire pulling end in the third trajectory, the space inside the wire pulling end is relatively large, which is convenient for the 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, the other end of the wire pulling member 2205 is facing the direction of the base 4, and a avoidance position 2209 is formed at the end, and 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, and an annular wire groove 2217 is arranged 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 limit assembly and a reciprocating limit 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 keeps detecting 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 arranged on the deflection base 2201, close to the bottom surface of the reciprocating base 2203, and the second detection piece 2213 is arranged 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 been lowered into place.

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

[0152] Furthermore, the wire supply module 2 also includes a limiting mechanism 24, such as Fig.10As shown, the limiting mechanism 24 includes a fixed seat 2401, a second clamping jaw cylinder 2402 and two limiting plates 2403. The fixed seat 2401 is arranged between the deflection base 2201 and the upper base 2101. The second clamping jaw cylinder 2402 is arranged on the fixed seat 2401. The two limiting plates 2403 are connected to the second clamping jaw cylinder 2402. The second clamping jaw 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 plate 2403, and the copper wire 5 avoidance position 2404 is above the hook wire avoidance space 2102 and below the wire pulling member 2205. When the two limiting plates 2403 are close to each other, the two copper wire 5 avoidance positions 2404 form a hook wire avoidance hole, and 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 hook needle 2303.

[0153] It is easy to understand, in combination with the accompanying drawings, that when the upper base 2101 is provided with the 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 supply mechanism outputs the copper wire 5, the two limiting pieces 2403 are in a state of being away from each other. Before the operation of winding the copper wire 5 begins, the two limiting pieces 2403 are close to each other, so that the copper wire 5 is in a state of passing through the hooking wire avoidance hole. In the subsequent winding operation, the two limiting pieces 2403 remain close to each other. When the hooking wire mechanism 23 pulls the copper wire 5 downward, the copper wire 5 can only pass through the hooking wire avoidance hole, that is, 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 supply module 3 stops conveying the copper wire 5, the copper wire 5 is not cut off first, which is equivalent to the wire supply module 3 fixing the top of the copper wire 5, and the wire hooking mechanism 23 and the wire pulling mechanism 22 are for the remaining copper wire 5. After the copper wire 5 near the bottom is wound, the wire supply module 3 cuts off the copper wire 5, and the wire hooking mechanism 23 and the wire pulling mechanism 22 then wind the copper wire 5 near the top. The above process is a conventional operation in this field, and the present invention will not repeat it.

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

[0157] The wire supply assembly 34 includes a wire feed guide wheel 3401, a wire feed motor 3402, a wire feed wheel 3403, a clamping cylinder 3404, a rotating frame 3407, a clamping wheel 3408, a cutter 3405 and a wire feed tube 3406. As shown in the figure, the wire feed guide wheel 3401 is arranged at the rear of the wire supply substrate 31, the wire feed wheel 3403 is horizontally and rotatably arranged above the wire supply substrate 31, the wire feed motor 3402 is arranged below the wire supply substrate 31, and the transmission shaft of the wire feed motor 3402 is connected to the wire feed wheel 3403 in a transmission manner, and the rotating frame 3407 is arranged on the wire supply substrate 31, located on one side of the wire feed wheel 3403, one side of the rotating frame 3407 is rotatably connected to the wire supply substrate 31, and the other side of the rotating frame 3407 remains free The clamping wheel 3408 is horizontally and rotatably arranged in the rotating frame 3407, and the clamping wheel 3408 is close to the wire feeding wheel 3403, and the copper wire 5 is between the clamping wheel 3408 and the wire feeding wheel 3403. The clamping cylinder 3404 is arranged on the side of the rotating frame 3407 away from the wire feeding wheel 3403, and the piston rod of the clamping 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 clamp 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. 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 supply module 3 is: first, the copper wire 5 is passed along the guide wheel through the clamping wheel 3408 and the wire feeding wheel 3403, and enters the wire feeding tube 3406. When the copper wire 5 needs to be transported, the piston rod of the clamping cylinder 3404 extends, pushing the rotating frame 3407 to move in the direction of the wire feeding wheel 3403, so that the clamping wheel 3408 applies pressure in the direction of the wire feeding wheel 3403, and the copper wire 5 is tightly clamped between the clamping 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 transported forward by friction. The length of the transported copper wire 5 can be obtained according to the circumference of the circular cross section of the wire feeding wheel 3403 and the number of rotations.

[0159] Before conveying the copper wire 5, the front end of the wire feeding tube 3406 is aligned with the middle of the substrate 4, and the copper wire 5 passes through the middle of the substrate 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 clamping wheel 3408 still keep the copper wire 5 clamped. Then the wire supply rotating motor 33 drives the wire supply assembly 34 to deflect an angle as a whole, so that the front end of the wire feeding tube 3406 is staggered with the substrate 4, which is convenient for the subsequent winding operation. When it is necessary to cut the copper wire 5, the cutter 3405 is started to cut the copper wire 5, and the copper wire 5 in the front is continued to be wound and used, and the copper wire 5 between the clamping 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 various. In the present invention, the cutter 3405 includes a baffle, a cutter and a cutter cylinder, the baffle and the cylinder body of the cutter cylinder are fixedly arranged on the wire feeding substrate, the cutter is arranged on the piston rod of the cutter cylinder, the cutter faces the baffle, and the copper wire 5 is 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 realize the orderly operation of the modules. The control module of the present invention is an existing conventional electrical control device, which will not be described in detail in the present invention.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
