Generally, a copper wire winding is wound around an iron core, which plays roles such as filtering and stabilizing current in the circuit. Generally, when manufacturing an inductive element, it is made by winding wire on the iron core through an inductive winding device.

Specifically, this inductive coil winding device continuously passes and winds a wire around an iron core through a clamping assembly. During the winding process, the clamping assembly needs to continuously rotate around the iron core, and the actions that the driving structure needs to achieve are complex, resulting in a high failure rate. Summary of the Invention

[0004] In order to improve the problem of complex actions, this application provides a method for manufacturing an inductive element and an inductive element.

[0005] In a first aspect, a method for manufacturing an inductive element provided by this application adopts the following technical solution:

[0006] A method for manufacturing an inductive element, implemented by a winding device, includes the following steps:

[0007] Drilling step: Drill an outlet hole at one end of the iron core and an inlet hole at the other end of the iron core;

[0008] Winding step: After the inlet end of the enameled wire passes through the iron core from the inlet hole, the iron core rotates and moves simultaneously, and the enameled wire is evenly wound on the surface of the iron core;

[0009] Cutting step: After winding is completed, cut the enameled wire to form an outlet end, and insert the outlet end into the outlet hole;

[0010] Polishing step: Polish the surface enamel of the inlet end and the outlet end to expose the copper core of the enameled wire, and it is completed.

[0011] By adopting the above technical solution, when winding the inductance, it only needs to drive the iron core to rotate and move parallel at the same time, and wind the enameled wire evenly on the iron core. The winding step of the iron core is completed, and during winding, the enameled wire can be inserted into the inlet hole to play a positioning role. And during the winding process, the position of the enameled wire is restricted by the inlet hole, and the enameled wire will not rotate with the iron core during the winding process, and the winding process is smoother.

The clamping rotation assembly is arranged on the mounting frame for clamping the iron core.

[0018] By adopting the above technical solution, the middle of the installation frame is hollowed out. When the clamping and rotating assembly clamps the iron core, the hollowed-out portion can reveal the entire iron core. As the clamping and rotating assembly moves with the installation frame, the drilling mechanism can drill holes in the iron core through the hollowed-out portion, forming inlet and outlet holes for the enameled wire to pass through. The lead screw can rotate in both directions, that is, it can drive the drilled iron core toward the enameled wire, first passing the enameled wire into the inlet hole, while the iron core can rotate, so that the enameled wire can be evenly wound around the iron core, thus completing the winding.

[0021] Optionally, the drilling mechanism includes a precession assembly and a drilling assembly. The precession assembly is arranged on the frame and is perpendicular to the translation assembly. The drilling assembly is arranged on the precession assembly and reciprocates along the precession assembly.

[0022] By adopting the above technical solution, the drilling assembly is on the precession assembly, so that the drilling assembly can reciprocate along the length direction of the iron core, and holes can be drilled at both ends of the iron core for the enameled wire to pass through.

[0023] Optionally, the precession assembly includes a longitudinal track and a mounting base b. The longitudinal track is fixed on the frame and is perpendicular to the translation assembly. The mounting base b is arranged on the longitudinal track and is driven by a track motor to move along the longitudinal track. The drilling assembly is fixed on the mounting base b and is used to drill an inlet hole and an outlet hole on the iron core.

[0024] By adopting the above technical solution, the mounting base b slides on the longitudinal track, driving the drilling mechanism to move so as to drill holes at different positions of the iron core.

The cutting assembly and the grinding assembly are respectively arranged on the frame. The conveying assembly is arranged at one end of the translation assembly. The conveying assembly is used for winding the enameled wire. The end of the enameled wire sequentially passes through the cutting assembly and the grinding assembly. When the iron core approaches the grinding assembly along the translation assembly, the end of the enameled wire is inserted into the inlet hole.

[0028] The conveying component includes a wire reel rotatably connected to the frame and a pair of guide wheels.

One of the guide wheels is driven by a motor to rotate, and the end of the enameled wire passes through between the pair of guide wheels;

[0029] A translation screw rod is provided on the frame. The translation screw rod is arranged perpendicular to the length direction of the frame. A translation seat is arranged on the translation screw rod for installing the guide wheel and the motor. The rotation of the translation screw rod drives the guide wheel to reciprocate along the translation screw rod;

[0031] By adopting the above technical solution, after the enameled wire is wound around the iron core, due to the cutting by the cutting component, at this time, the enamel on the end surface of the enameled wire needs to be exposed. Therefore, the polishing component can perform polishing to complete the processing of the inductance element.

[0044] The following is a further detailed description of the present application in conjunction with the attached Figures 1-5 This application is further described in detail below.

[0045] The embodiment of the present application discloses a method for manufacturing an inductance element. A method for manufacturing an inductance element, the method at least includes the following steps:

[0046] Drilling step: Drill an outlet hole at one end of the iron core and an inlet hole at the other end of the iron core. Drilling the inlet hole is to be able to pre-insert the enameled wire into the inlet hole when winding the wire around the iron core, so as to realize the positioning and limiting functions of the enameled wire during winding. During the winding process, the enameled wire is wound more evenly, and at the same time, the enameled wire is not prone to follow rotation during the winding process, making the winding faster and more convenient.

[0047] Winding step: After the inlet end of the enameled wire passes through the iron core from the inlet hole, the iron core rotates and moves simultaneously, and the enameled wire is evenly wound on the surface of the iron core. The rotation and movement of the iron core are both at a constant speed, so it is more uniform and faster during the winding process of the enameled wire, and the processing efficiency of the inductance element is higher.

[0048] Cutting step: After winding is completed, cut the enameled wire to form an outlet end, and insert the outlet end into the outlet hole. In this way, the enameled wire reel 1211 can be used for processing, and the enameled wire can be cut after each inductance element is manufactured. The enameled wire on the enameled wire reel 1211 can be used to process the next inductance element, enabling the processing to proceed continuously with higher processing efficiency.

[0049] Polishing step: Polish the surface enamel of the inlet end and the outlet end to expose the copper core of the enameled wire. After the inductance winding is completed, the inductance winding needs to be connected to other components to be used, so the inlet end and the outlet end need to be polished. The entire processing process involves less manual participation and has high processing efficiency.

[0050] To implement this method for manufacturing an inductance element, the present application also describes a winding device 1. Refer to Figure 1 , the winding device 1 includes a drilling mechanism 11, a wire feeding mechanism 12, and a conveying mechanism 13. The drilling mechanism 11, the wire feeding mechanism 12, and the conveying mechanism 13 are all arranged on the frame 2. Among them, the drilling mechanism 11 is arranged at one end of the frame 2, the wire feeding mechanism 12 is arranged at the other end of the frame 2, and the conveying mechanism 13 clamps the iron core and reciprocates between the drilling mechanism 11 and the wire feeding mechanism 12. When the iron core moves towards the drilling mechanism 11, the drilling mechanism 11 drills an inlet hole and an outlet hole in the iron core. The inlet hole is used to insert the enameled wire so that the enameled wire will not have abnormal displacement when being wound around the iron core, so that the enameled wire can be wound more evenly on the iron core during winding.

[0051] Refer to Figure 1 and Figure 2 , the conveying mechanism 13 includes a translation component 131 and a clamping and rotating component 132. The translation component 131 moves along the length direction of the frame 2, and the clamping and rotating component 132 is used to clamp the iron core and is driven to rotate by an independent servo motor, thereby driving the iron core to rotate. The clamping and rotating component 132 moves along the translation component 131, so as to be able to drive the iron core to move from one end of the frame 2 where the drilling mechanism 11 is arranged to the other end of the frame 2 where the wire feeding mechanism 12 is arranged.

[0052] Referring to Figure 1 and Figure 2 Figure 2 , the translation component 131 includes a transverse rail 1311, a mounting frame 1312 and a lead screw 1313. The mounting frame 1312 is used to mount the clamping and rotating component 132. The transverse rail 1311 is fixed on the frame 2 and arranged along the length direction of the frame 2. There is at least a pair of transverse rails 1311, and a pair of transverse rails 1311 are parallel to each other. The lead screw 1313 is placed between a pair of transverse rails 1311 and fixed on the frame 2. The lead screw 1313 is also parallel to the transverse rail 1311. One end of the lead screw 1313 faces the drilling mechanism 11, and the other end of the lead screw 1313 faces the wire feeding mechanism 12. The clamping and rotating component 132 is sleeved on the lead screw 1313 and the transverse rail 1311 also penetrates through the clamping and rotating component 132. The lead screw 1313 can be driven to rotate by a servo motor fixed on the frame 2. When the lead screw 1313 rotates, the clamping and rotating component 132 can reciprocate along the transverse rail 1311, so that the iron core clamped by the clamping and rotating component 132 can reciprocate between the drilling mechanism 11 and the wire feeding mechanism 12.

[0053] Referring to Figure 1 and Figure 2 Figure 2 , the clamping and rotating component 132 is arranged on the frame 2 in an axisymmetric manner for clamping the iron core. The clamping and rotating component 132 includes a thimble 1321, a mounting seat a 1322 and a cylinder 1323. A rotating shaft is fixed on one end face of the mounting seat a 1322. The rotating shaft is rotatably connected to the frame 2. By rotating the rotating shaft, the mounting seat a 1322 can rotate. The rotating shaft can be driven to rotate by a motor 1324 so that the mounting seat a 1322 can rotate. The cylinder 1323 is mounted on the mounting seat a 1322. The thimble 1321 is fixed to the drive shaft of the cylinder 1323 so that the thimble 1321 can reciprocate telescopically. The iron core is placed between a pair of thimbles 1321 and clamped by the thimbles 1321. In order to make the clamping more stable, a perforation can be drilled in advance at the center of the iron core. The perforation is drilled along the central axis of the iron core. When the thimble 1321 clamps, it can be inserted into the perforation to make the clamping more stable. By controlling the stroke of the cylinder 1323, the position of the iron core can be adjusted so that the iron core can reciprocate relative to the wire feeding mechanism 12. When the wire feeding mechanism 12 feeds the wire, it can drive the enameled wire to be evenly wound on the iron core.

[0054] Referring to Figure 1 and Figure 3, when the conveying mechanism 13 holds the iron core, it first needs to move towards the drilling mechanism 11. The drilling mechanism 11 drills an inlet hole and an outlet hole on the side wall of the iron core. The inlet hole and the outlet hole are perpendicular to the perforation and penetrate through the iron core for the enameled wire after winding to pass through. The drilling mechanism 11 includes a precession component 111 and a drilling component 112. The precession component 111 is fixed on the frame 2 and perpendicular to the moving direction of the iron core. The drilling component 112 is arranged on the precession component 111 and can reciprocate to facilitate drilling the inlet hole and the outlet hole at the position near the end of the side wall of the iron core.

[0055] Refer to Figure 1 and Figure 3 , the precession component 111 includes a longitudinal track 1111 and a mounting seat b1112. The longitudinal track 1111 is fixed on the frame 2 and parallel to the central axis of the iron core. The mounting seat b1112 is driven by the motor 1324 so that the mounting seat b1112 can slide on the longitudinal track 1111. The drilling component 112 is fixed on the mounting seat b1112. The drilling component 112 includes a drilling machine 1121 and a drill bit 1122. The drilling machine 1121 is fixedly connected to the mounting seat b1112, and the drill bit 1122 is installed on the drilling machine 1121 and driven by the drilling machine 1121 to rotate. When drilling the inlet hole, the mounting seat b1112 moves driven by the motor 1324 to align the drill bit 1122 with the end of the iron core. Then the iron core moves towards the drill bit 1122 direction, and the drill bit 1122 is driven by the drilling machine 1121 to rotate for drilling operation. When drilling the outlet hole, it is still the movement of the mounting seat b1112 that drives the drill bit 1122 to move, and finally the drill bit 1122 is aligned with the other end of the iron core for drilling operation.

[0056] Refer to Figure 1 and Figure 4 After the drilling operation is completed, the lead screw 1313 rotates to drive the iron core to move towards the wire feeding mechanism 12. The wire feeding mechanism 12 includes a conveying component 121, a cutting component 122 and a grinding component 123. The conveying component 121 holds and conveys the enameled wire. The conveying component 121 includes a wire reel 1211 rotatably connected to the frame 2 and a pair of guide wheels 1212. The enameled wire is wound on the wire reel 1211.

[0057] Refer to Figure 4 and Figure 5, a pair of guide wheels 1212 are in mutual contact, and one of the guide wheels 1212 is a driving wheel, directly driven by a motor to rotate. When the enameled wire is inserted between the pair of guide wheels 1212, the guide wheels 1212 can use friction to convey the enameled wire forward. At this time, the thimble 1321 moves towards the wire feeding mechanism 12. By controlling the stroke of the cylinder 1323, the position of the iron core can be adjusted to align the wire inlet hole with the position of the enameled wire, so that the end of the enameled wire can be inserted into the iron core. Of course, a translation lead screw 1213 can also be provided on the frame 2. The translation lead screw 1213 is perpendicular to the axis of the iron core. The translation lead screw 1213 is driven by an independent servo motor. A translation seat 1214 is sleeved on the translation lead screw 1213 for installing the guide wheels 1212 and the motor. An auxiliary track is also fixed on the frame 2. The auxiliary track is parallel to the translation lead screw 1213 and penetrates through the translation seat 1214. It plays a role in limiting and guiding when the translation seat 1214 moves along the translation lead screw 1213. When winding the enameled wire around the iron core, it moves relative to the iron core, driving the enameled wire to be evenly wound around the iron core.

[0058] Refer to Figure 4 and Figure 5 , after being conveyed by the wire feeding assembly, the end of the enameled wire needs to be polished by the polishing assembly 123 before it can penetrate into the wire inlet hole. The polishing assembly 123 includes a first polishing seat 1231, a second polishing seat 1232 and a linear motor 1233. The linear motor 1233 is fixed on the translation seat 1214. The second polishing seat 1232 is fixed on the translation seat 1214 and is placed below the linear motor 1233. The first polishing seat 1231 is connected to the linear motor 1233. When polishing is required, the linear motor 1233 directly drives the first polishing seat 1231 to move towards the second polishing seat 1232 to clamp the enameled wire. At this time, since the guide wheels 1212 continuously push the enameled wire, the end of the enameled wire rubs against the first polishing seat 1231 and the second polishing seat 1232, grinding off the enamel on the surface of the enameled wire.

[0059] Refer to Figure 4 and Figure 5, after the enameled wire is wound around the iron core, it is cut by the cutting assembly 122. After cutting, the other end of the enameled wire wound around the iron core is also polished by the polishing assembly 123 so that both ends of the enameled wire are exposed for easy connection with other parts. The cutting assembly 122 includes a driving part and a cutting part 1222. The enameled wire passes between the cutting parts 1222. When the enameled wire needs to be cut, the driving part can drive the cutting part 1222 to cut the enameled wire. The driving part at least includes a hydraulic cylinder 1221. The hydraulic cylinder 1221 is fixed on the translation seat 1214. The hydraulic cylinder 1221 drives the cutting part 1222 to cut the enameled wire. The cutting part 1222 includes a cutting knife 12222 and a cutting seat 12221. The cutting seat 12221 is fixed on the translation seat 1214 and is placed opposite to the hydraulic cylinder 1221. The enameled wire passes between the cutting knife 12222 and the cutting seat 12221. The cutting knife 12222 is fixed on the hydraulic cylinder 1221 and is driven by the hydraulic cylinder 1221 to drive the cutting knife 12222 to move towards the cutting seat 12221 to cut the enameled wire.

[0060] When using the winding device 1 to produce inductance components, first, the iron core needs to be clamped by the ejector pin 1321. The ejector pin 1321 is inserted into the through hole and abuts against the iron core. After clamping, the lead screw 1313 drives the iron core to move towards the drill bit 1122. The drill bit 1122 rotates to first drill an inlet hole, and then the drill bit 1122 moves along the vertical track until the drill bit 1122 moves to the other end of the iron core to drill an outlet hole.

[0061] Secondly, after the inlet hole and the outlet hole are drilled on the iron core, the lead screw 1313 drives it to move towards the wire feeding mechanism 12. The wire feeding mechanism 12 is started, and the guide wheel 1212 rotates to convey one end of the enameled wire forward, passing through the cutting part 1222 and the polishing assembly 123 in sequence. The end is polished by the polishing assembly 123 and finally extends out of the polishing assembly 123. When the iron core moves close to the polishing assembly 123, the translation seat 1214 moves so that the inlet hole of the iron core is coaxial with the enameled wire; or the position of the ejector pin 1321 is adjusted by the air cylinder 1323 so that the inlet hole of the iron core is coaxial with the enameled wire; the iron core continues to move, and the end of the enameled wire passes out of the inlet hole.

[0062] Then, the ejector pin 1321 rotates to drive the iron core to rotate. Since the end of the enameled wire is inserted into the inlet hole at this time, the rotation of the iron core can wind the enameled wire around the surface of the iron core. While the iron core is rotating, the translation seat 1214 moves towards the outlet hole direction so that the enameled wire can be evenly wound around the surface of the iron core. During the winding process, the first polishing seat 1231 and the second polishing seat 1232 are separated from each other, so that the polishing assembly 123 can only polish the end of the enameled wire.

[0063] Subsequently, after the enameled wire winding is completed, the enameled wire is cut by the cutting component 122 to form another end. As the iron core rotates, the other end also passes through the grinding component 123 for grinding, so that the core wires of both ends of the enameled wire wound around the iron core are exposed, facilitating connection with other parts.

[0064] Finally, when the end of the enameled wire wound around the iron core disengages from the grinding component 123, the ejector pin 1321 stops rotating, and the iron core is removed. The operator manually inserts the end of the enameled wire into the wire outlet hole. Only manual feeding and discharging are involved in the whole process, with less manual participation and high production efficiency. And during the winding process, only the parallel movement and rotation of each part need to be controlled, and the control logic is simple with low failure rate.

[0065] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
