Description

Technical Field

[0001] This invention relates to the field of inductor processing technology, and more particularly to an inductor processing apparatus and an inductor processing method using the same. Background Technology

[0002] The traditional method for inductor manufacturing involves first clamping an I-shaped magnetic core onto a winding machine fixture, then using the winding machine to wind a coil onto the I-shaped core. The coiled I-shaped core is then removed from the winding machine fixture and placed inside a magnetic shield. The wires are then separated and aligned precisely with the pads on the magnetic shield. Finally, the magnetic shield is placed on a spot welding machine fixture, where spot welding is performed to solder the wire ends to the pads on the magnetic shield, resulting in the finished inductor. However, inductors are small in size, with the diameter of the wire wound on the I-shaped core being less than 0.1 mm. This process is cumbersome, difficult, and inefficient, making it hard to guarantee the integrity of the wire, the processing accuracy, and the performance quality of the inductor. Summary of the Invention

[0003] The technical problem to be solved and the technical task proposed by the present invention is to improve the existing technology and provide an inductor processing device to solve the problems of cumbersome, difficult, inefficient and low-precision inductor processing in the current technology.

[0004] To solve the above technical problems, the technical solution of the present invention is as follows: An inductor processing apparatus includes a main body, a magnetic core carrier, a magnetic cover carrier, a driving mechanism, and a wire end fixing mechanism. The magnetic core carrier is used to hold a magnetic core, and the magnetic cover carrier is used to hold a magnetic cover. The magnetic core carrier and / or the magnetic cover carrier are respectively reciprocally slidably disposed on the main body along a first direction, the first direction being the direction in which the magnetic core enters and exits the magnetic cover. The driving mechanism drives the magnetic core carrier and the magnetic cover carrier to move relative to each other along the first direction. The main body is provided with a plurality of wire end fixing mechanisms for fixing the wire ends of coils wound on the magnetic core, and the wire end fixing mechanisms are circumferentially spaced along the first direction. The inductor processing apparatus of this invention is used for both coil winding and welding of inductors. The magnetic core and magnetic cover do not need to be moved between multiple fixtures, effectively improving processing accuracy and efficiency. Because the magnetic core support and the magnetic cover support can move relative to each other along a first direction, the magnetic core can easily enter and exit the magnetic cover. In other words, it can freely and flexibly switch between a state where the magnetic core is exposed outside the magnetic cover and a state where the magnetic core is inside the magnetic cover. Therefore, coil winding can be performed when the magnetic core is exposed outside the magnetic cover. Then, the wire end is fixed by the wire end fixing mechanism, that is, fixing the orientation of the wire end so that the wire end faces the pad of the magnetic cover. Since the magnetic core is exposed outside the magnetic cover at this time, although the wire end is in the orientation of the pad, there is a lateral force between the wire end and the pad. The spacing in the first direction is then adjusted by the drive mechanism. The magnetic core carrier and the magnetic cover carrier move relative to each other in the first direction to switch the magnetic core to a state where the magnetic cover is located inside the magnetic cover. The spacing between the wire end and the pad in the first direction is eliminated, and the wire end can be precisely attached to the pad, thus facilitating the welding operation and fixing the wire end to the pad. Compared with the traditional inductor processing method, the operation is more convenient and simple, effectively improving the processing efficiency. During the coil winding and welding processes, the magnetic core and the magnetic cover are both on the inductor processing device of this invention, eliminating the need for separate transfer of the magnetic core and the magnetic cover. This effectively ensures the relative positional accuracy between the magnetic core and the magnetic cover, thereby effectively improving the processing accuracy of the product and ensuring that the product has good and consistent performance.

[0005] Furthermore, the magnetic cover is provided with a through-hole cavity for storing and accommodating the magnetic core. The magnetic core carrier passes through the through-hole cavity to support and place the magnetic core. The structure is simple. The relative movement between the magnetic core carrier and the magnetic cover carrier along the first direction can easily switch the magnetic core and the magnetic cover between the state where the magnetic core is exposed outside the magnetic cover and the state where the magnetic core is inside the magnetic cover, thereby facilitating and accurately performing coil winding and welding operations.

[0006] Furthermore, the magnetic cover support is a cylindrical component that surrounds the circumferential periphery of the magnetic core support. It has a simple structure and is easy to process and implement. The magnetic core support and the magnetic cover support can reliably support the magnetic core and the magnetic cover respectively, and there is no interference between the relative movement of the magnetic core support and the magnetic cover support in the first direction.

[0007] Furthermore, the magnetic cover support is provided with a cavity for positioning and placing the magnetic cover, which improves the placement accuracy of the magnetic cover, thereby improving the assembly and processing accuracy and ensuring that the wire end of the coil can be accurately aligned with the solder pad of the magnetic cover.

[0008] Furthermore, the wire end fixing mechanism includes a clamping component for clamping the wire end. The clamping component is an elastic clamping component, which elastically clamps and fixes the wire end. The fixing operation is convenient and can avoid excessive fixing force on the wire end, thus preventing the wire end from being clamped and breaking. This ensures the reliability of the wire end fixing and ensures that the wire end is accurately aligned with the solder pads of the magnetic cover, facilitating subsequent accurate soldering.

[0009] Furthermore, the clamping assembly is adjustable along the first direction. Since there is relative movement between the magnetic core support and the magnetic cover support along the first direction, the wire end may be over-tightened, which can easily lead to wire breakage. The clamping assembly can effectively fix the wire end by moving in the first direction, and at the same time, it can adapt to the relative movement between the magnetic core support and the magnetic cover support along the first direction to avoid the wire end being over-tightened and ensure the integrity of the wire end.

[0010] Furthermore, the wire end fixing mechanism is adjustable in the circumferential direction of the first direction, which improves the flexibility and applicability of the inductor processing device. It can be used to process inductors of different specifications and models. The location of the pads on the magnetic cover of inductors of different specifications and models is different. The direction and position of the fixed wire end can be adjusted by adjusting the wire end fixing mechanism in the circumferential direction of the first direction, so as to ensure that the wire end is aligned with the pads on the magnetic cover when processing different inductors, thus ensuring processing accuracy and expanding the range of applications.

[0011] Furthermore, the driving mechanism includes a pushing member and an elastic member. The pushing member is movably mounted on the main body to push the magnetic core carrier and / or the magnetic cover carrier. The elastic member is used to drive the pushing member to reset. The structure is simple and easy to implement. An external force drives the pushing member to move, which in turn pushes the magnetic core carrier and / or the magnetic cover carrier to move along a first direction, causing relative movement between the magnetic core carrier and the magnetic cover carrier along the first direction. The elastic member driving the pushing member to reset also drives the magnetic core carrier and / or the magnetic cover carrier to reset. In other words, through the cooperation of the pushing member and the elastic member, the magnetic core and magnetic cover can be freely and flexibly switched between a state where the magnetic core is exposed outside the magnetic cover and a state where the magnetic core is inside the magnetic cover.

[0012] Furthermore, it also includes a clamping assembly, which is detachably connected to the main body. When the clamping assembly is connected to the main body, it presses the magnetic core onto the magnetic core carrier. The clamping assembly keeps the magnetic core stably in place on the magnetic core carrier, preventing the magnetic core from shifting when the entire inductor processing device is transferred. This ensures the magnetic core is in a precise and stable position, facilitating subsequent precise welding and ensuring product processing accuracy.

[0013] Furthermore, the clamping assembly is connected to the main body via a magnetic adsorption assembly, which facilitates easy assembly and disassembly and improves overall processing efficiency. The coil wire ends are already fixed by the wire end fixing mechanism, thus providing a certain degree of force to hold the magnetic core on the magnetic core carrier. Only a small additional force is needed to stably hold the magnetic core on the magnetic core carrier. The magnetic force generated by the magnetic adsorption assembly is sufficient to meet the requirements and ensure that the magnetic core does not shift, thereby ensuring accurate welding can be performed subsequently.

[0014] Furthermore, the magnetic adsorption assembly includes a first component disposed on the main body and a second component disposed on the pressing assembly. The first component and the second component are magnetically attracted to each other. One of the first component and the second component is provided with a positioning hole, and the other component is provided with a corresponding positioning post. The cooperation between the positioning hole and the positioning post allows the first component and the second component to be precisely attracted to each other, thereby enabling the pressing assembly to accurately press the magnetic core and improve the reliability of pressing and fixing the magnetic core.

[0015] Furthermore, the clamping assembly includes a pressure plate for contacting the magnetic core. The pressure plate has working holes for exposing the pads of the magnetic shield, which ensures reliable clamping and fixing of the magnetic core without affecting the welding operation, and ensures that the wire ends can be accurately welded to the pads.

[0016] The inductor processing method using the above-mentioned inductor processing apparatus includes the following steps: The inductor processing device is placed on the winding equipment, the magnetic cover is placed on the magnetic cover support, and the magnetic core is placed on the magnetic core support. With the magnetic core exposed outside the magnetic cover, the magnetic core is pressed tightly against the magnetic core carrier by the top core. The wire ends at the head of the wire are fixed by different wire end fixing mechanisms. The winding equipment starts to wind the wire onto the magnetic core. The wire ends at the tail of the wire are fixed by different wire end fixing mechanisms, and the wire ends are aligned with the pads of the magnetic cover. A clamping assembly is installed on the main body to press the magnetic core onto the magnetic core carrier; The inductor processing device is placed on the welding equipment. When the inductor processing device is in place, the drive mechanism is activated to perform the action. The drive mechanism drives the magnetic core carrier and the magnetic cover carrier to move relative to each other in the first direction so that the magnetic core enters the magnetic cover and the wire end is connected to the solder pad of the magnetic cover. The welding equipment welds the wire ends to the pads of the magnetic cover to obtain the product.

[0017] Compared with traditional inductor processing methods, the inductor processing method described in this invention eliminates the need to frequently transfer the magnetic core and magnetic cover between multiple devices or fixtures, eliminates the need for manual wire handling, and enables both coil winding and welding operations to be performed on a single inductor processing device. This effectively improves processing efficiency, prevents wire loss, ensures the relative positional accuracy between the magnetic core and magnetic cover, improves product processing accuracy, and enhances product performance and quality consistency.

[0018] Compared with the prior art, the advantages of this invention are: The inductor processing apparatus and method described in this invention eliminate the need to frequently transfer the magnetic core and magnetic cover between multiple devices or fixtures. Coil winding and welding operations are performed on the same device, eliminating the need for manual wire handling, effectively improving processing efficiency, preventing wire loss, and effectively ensuring the relative positional accuracy between the magnetic core and magnetic cover. This effectively improves the processing accuracy of the product and ensures that the product has good and consistent performance. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0022] The inductor processing apparatus disclosed in this invention effectively reduces processing difficulty, improves processing efficiency, enhances processing accuracy, and ensures the quality and performance of the inductor.

[0023] like Figures 1 to 11As shown, an inductor processing device mainly includes a main body 1, a magnetic core carrier 2, a magnetic cover carrier 3, a driving mechanism 4, and a wire end fixing mechanism 5. The magnetic core carrier 2 is used to hold a magnetic core 6, and the magnetic cover carrier 3 is used to hold a magnetic cover 7. In this embodiment, the magnetic core carrier 2 is fixedly mounted on the main body 1, while the magnetic cover carrier 3 is reciprocally slidably mounted on the main body 1 along a first direction, which is the direction in which the magnetic core 6 enters and exits the magnetic cover 7. This allows relative displacement between the magnetic cover carrier 3 and the magnetic core carrier 2 along the first direction, thereby enabling the magnetic core mounted on the magnetic core carrier 2 to enter and exit the magnetic cover 7 mounted on the magnetic cover carrier 3 along the first direction. In other words, it enables switching between the state where the magnetic core 6 is exposed outside the magnetic cover 7 and the state where the magnetic core 6 is located inside the magnetic cover 7. The driving mechanism 4 is mounted on the main body 1 to drive the magnetic cover carrier 3 to move along the first direction. The magnetic core support 2 and the magnetic cover support 3 move relative to each other along the first direction. The main body 1 is provided with a plurality of wire end fixing mechanisms 5. The wire end fixing mechanisms 5 are used to fix the wire ends of the coil 61 wound on the magnetic core 6. The wire end fixing mechanisms 5 are distributed circumferentially along the first direction. Generally, there are an even number of wire end fixing mechanisms 5. Each wire of the coil 61 wound on the magnetic core 6 has two wire ends, a head and a tail. Each wire end is fixed by a wire end fixing mechanism 5. When the wire end is fixed by the wire end fixing mechanism 5, the wire end is facing the pad on the magnetic cover 7. The pad is distributed circumferentially along the first direction. The wire end fixing mechanism 5 makes the wire ends distributed circumferentially along the first direction and fixed, so that the wire ends and the pads are precisely aligned one by one, which facilitates the subsequent precise welding of the wire ends and the pads.

[0024] like Figure 1 As shown, the magnetic cover 7 is provided with a through-hole cavity for storing and accommodating the magnetic core 6. The magnetic core support member 2 passes through the through-hole cavity to support and place the magnetic core 6. Specifically, the magnetic core support member 2 is shaped like a slender rod along a first direction. The magnetic core support member 2 can pass smoothly and without obstruction through the through-hole cavity of the magnetic cover 7 and realize the function of supporting and placing the magnetic core 6. When the magnetic cover support member 3 and the magnetic core support member 2 undergo relative displacement along the first direction, no interference will occur, thereby enabling the magnetic core 6 to freely and conveniently enter and exit the magnetic cover 7. In this embodiment, as shown... Figures 3 to 7As shown, the magnetic cover support 3 is a cylindrical member surrounding the magnetic core support 2. Specifically, the magnetic cover support 3 is a straight cylindrical member with its axial direction along the first direction. The magnetic cover 7 is also a cylindrical member surrounding the magnetic core 6. Thus, the magnetic cover support 3 can reliably hold and support the magnetic cover 7. When the magnetic cover support 3 moves relative to the magnetic core support 2 along the first direction, the magnetic core 6 moves in and out of the magnetic cover 7 along the first direction. The magnetic cover support 3 is provided with a cavity 31 for positioning and placing the magnetic cover 7. Specifically, the end of the cylindrical magnetic cover support 3 has a stepped groove that matches the external dimensions of the magnetic cover 7 to form the cavity 31. The magnetic cover 7 is embedded in the cavity 31 to ensure the placement accuracy of the magnetic cover 7, thereby ensuring the subsequent processing accuracy. The magnetic cover support 3 can also be a number of pillars distributed around the magnetic core support 2, which can also serve to place and support the magnetic cover 7. In addition, the magnetic cover support 3 can move relative to the magnetic core support 2 in the first direction without interference, thereby realizing the magnetic core 6 entering and exiting the magnetic cover 7 in the first direction.

[0025] like Figure 6 and Figure 7 As shown, the driving mechanism 4 includes a pushing member 41 and an elastic member 42. The pushing member 41 is movably mounted on the main body 1 to push the magnetic core support member 2 and / or the magnetic cover support member 3. The elastic member 42 is used to drive the pushing member 41 to reset. Specifically, the pushing member 41 is slidably mounted on the main body 1 along a first direction. The pushing member 41 specifically includes two straight push rods along the first direction, which are distributed on both sides of the magnetic core support member 2 in the diameter direction. One end of the pushing member 41 faces the end side of the magnetic cover support member 3, and the other end of the pushing member 41 protrudes from the main body 1. Externally, the magnetic cover support 3 is driven to move along the first direction by pushing the outer end of the pusher 41. The elastic member 42 is a spring sleeved on the magnetic cover support 3. The elastic member 42 is used to drive the magnetic cover support 3 to reset along the first direction, that is, to drive the pusher 41 to reset. The pusher 41 pushes the magnetic cover support 3 to move along the first direction to switch the state of the magnetic core 6 exposed outside the magnetic cover 7 to the state of the magnetic core 6 located inside the magnetic cover 7. The elastic member 42 is used to reset the state of the magnetic core 6 located inside the magnetic cover 7 to the state of the magnetic core 6 exposed outside the magnetic cover 7.

[0026] The pusher 41 can also be slidably mounted on the main body 1 perpendicular to the first direction. The pusher 41 pushes the magnetic cover support 3 by means of the inclined surface portion in the first direction. The inclined surface portion can be mounted on the pusher 41, or on the magnetic cover support 3, or both the pusher 41 and the magnetic cover support 3 can be provided with inclined surfaces. This can also easily realize the movement of the magnetic cover support 3 along the first direction, thereby realizing the switching between the state where the magnetic core 6 is exposed outside the magnetic cover 7 and the state where the magnetic core 6 is located inside the magnetic cover 7.

[0027] The wire end fixing mechanism 5 includes a clamping component 51 for holding the wire end. The clamping component 51 is an elastic clamping component, which uses elastic clamping to fix the wire end, making operation convenient, ensuring processing efficiency, and avoiding excessive clamping force that could cause the wire end to break. This ensures reliable fixing of the wire end while protecting its integrity. In this embodiment, as... Figure 8 As shown, the clamping assembly 51 includes a first clamp 511, a second clamp 512, a clamp nut 514, and a clamp spring 513. The first clamp 511 passes through the through hole of the second clamp 512 and is connected to the clamp nut 514. The clamp spring 513 is disposed between the clamp nut 514 and the second clamp 512. The clamp spring 513 drives the first clamp 511 and the second clamp 512 to elastically and tightly adhere to each other to clamp the wire end between the first clamp 511 and the second clamp 512. Specifically, the first clamp 511 is generally rod-shaped, with a clamping part one at one end and a threaded section at the other end. The second clamp 512 is generally sleeve-shaped, with a clamping part two at the end facing the clamping part one. The threaded end of the first clamp 511 passes through the sleeve-shaped second clamp 512 and is screwed onto the clamp nut 514. The clamp spring 513 is sleeved on the first clamp 511 and located between the clamp nut 514 and the second clamp 512. The wire end of coil 61 is clamped between clamping part one and clamping part two. The clamping part one 511 and clamping nut 514 are screwed together and adjustable to adjust the deformation of clamping spring 513, thereby adjusting the clamping force of clamping part one 511 and clamping part two 512 on the wire end. It can adapt to wire ends of different diameters, ensuring that the wire end can be reliably and stably clamped and fixed without generating excessive clamping force on the wire end. The clamping component 51 in this embodiment has a simple structure and the clamping and fixing operation is convenient and quick.

[0028] Furthermore, at least one of the clamping parts one and clamping parts two is provided with a wire-holding groove 515 for receiving the wire end. The wire end is embedded in the wire-holding groove 515 and clamped between the clamping parts one and clamping parts two. This method can clamp and fix the wire end more accurately, thereby ensuring that the wire end is accurately aligned with the pad of the magnetic cover 7, and can effectively avoid damage to the wire end when clamping and fixing the wire end.

[0029] Coil winding can only be performed when the magnetic core 6 is exposed outside the magnetic cover 7. Subsequent welding operations require the magnetic core 6 to be inside the magnetic cover 7 to solder the wire ends to the pads on the magnetic cover 7. After coil winding is completed, the wire ends are effectively fixed by the wire end fixing mechanism 5, and are already taut. When the magnetic core 6 moves into the magnetic cover 7, the pads on the magnetic cover 7 press against the wire ends, further tightening them. This can easily lead to over-tightening and breakage. Therefore, an adjustable clamping assembly along the first direction is used to avoid over-tightening of the wire ends. Specifically, as shown... Figure 3 and Figure 8 As shown, the wire end fixing mechanism 5 includes a connecting block 52, which is connected to the main body 1. The clamping component 51 is slidably disposed in a through hole opened on the connecting block 52 along a first direction. An ejector spring 53 is provided between the clamping component 51 and the connecting block 52, so that the clamping component 51 can move elastically along the first direction as a whole. When the magnetic core carrier 2 moves along the first direction to allow the magnetic core 6 to enter the magnetic cover 7, the clamping component 51 moves in the same direction as the magnetic core carrier 2 along the first direction to compress the ejector spring 53, thereby avoiding excessive tension on the wire end. When the magnetic core carrier 2 moves in the opposite direction, the ejector spring 53 releases its elastic force to drive the clamping component 51 to move in the same direction as the magnetic core carrier 2 along the first direction.

[0030] Different models and specifications of inductors have different magnetic covers, and the pads on the magnetic covers have different positions. In order to increase the applicability of the inductor processing device and to process different inductors, the wire end fixing mechanism 5 is adjustable in the circumferential direction of the first direction. Specifically, the main body 1 is provided with fixing holes, and the wire end fixing mechanism 5 is provided with a long groove along the circumferential direction of the first direction. The long groove can be set in the connecting block 52. After the bolt passes through the long groove, it is locked in the fixing hole. The wire end fixing mechanism 5 slides along the direction of the long groove to adjust the position of the wire end fixing mechanism 5 in the circumferential direction of the first direction, so that the wire end fixing mechanism 5 and the pads of the magnetic cover 7 are aligned one-to-one. This ensures that the wire end and the pads of the magnetic cover 7 are precisely aligned, ensuring the subsequent welding accuracy and quality, and improving the product processing quality.

[0031] like Figures 9 to 11 As shown, the inductor processing device also includes a clamping assembly 8, which is detachably connected to the main body 1. When the clamping assembly 8 is connected to the main body 1, it presses the magnetic core 6 onto the magnetic core carrier 2. When the coil is wound, the clamping assembly 8 is removed from the main body 1, so that the clamping assembly 8 does not affect the coil winding process. After the coil is wound, the clamping assembly 8 is installed back onto the main body 1, so that the clamping assembly 8 reliably presses the magnetic core 6 onto the magnetic core carrier 2, keeping the position of the magnetic core 6 accurate and stable, avoiding displacement of the magnetic core when the entire inductor processing device is transferred, and ensuring accurate welding processing in the future.

[0032] In this embodiment, the clamping assembly 8 is connected to the main body 1 via a magnetic adsorption assembly 81, which facilitates quick and easy assembly and disassembly, improving efficiency. Specifically, the magnetic adsorption assembly 81 includes a first component 811 and a second component 812. The first component 811 and the second component 812 are magnetically attracted to each other. The first component 811 is disposed on the main body 1, and the second component 812 is disposed on the clamping assembly 8. One of the first component 811 and the second component 812 is provided with a positioning hole 813, and the other is provided with a corresponding positioning post 814. The cooperation between the positioning hole and the positioning post ensures that the first component and the second component are precisely aligned. The magnetic adsorption components 8 and 812 are magnetically attracted to each other, thereby ensuring that the clamping components accurately press the magnetic core and improving the reliability of the magnetic core clamping and fixing. Specifically, component 811 is a ring magnet, and component 812 can be a magnetic component or a metal component such as iron. Component 811 and component 812 are magnetically attracted to each other to achieve a detachable connection between the clamping components 8 and the main body 1. Several magnetic adsorption components 81 can be provided and distributed circumferentially along the first direction to improve the stability and reliability of the connection between the clamping components 8 and the main body 1, so that the clamping components 8 can accurately and stably press the magnetic core onto the magnetic core support component 2.

[0033] The clamping assembly 8 specifically includes a clamping plate 82 for contacting the magnetic core 6. The clamping plate 82 has a working hole 821 for exposing the solder pads of the magnetic cover 7, which ensures reliable clamping and fixing of the magnetic core without affecting the welding operation. The spot welding machine welds the wire end to the solder pads of the magnetic cover 7 through the working hole 821.

[0034] The inductor processing method of the above-mentioned inductor processing apparatus includes the following steps: The inductor processing device is placed on the winding machine. The clamps on the winding machine clamp and fix the inductor processing device. The magnetic cover 7 is placed on the magnetic cover support 3 of the inductor processing device, and the magnetic core 6 is placed on the magnetic core support 2 of the inductor processing device. In other words, the magnetic core 6 and the magnetic cover 7 are loaded into one inductor processing device at one time. With the magnetic core 6 exposed outside the magnetic cover 7, the top core 9 is used to press the magnetic core 6 firmly against the magnetic core support 2 (e.g., Figure 12 As shown), the wire is then wound onto the magnetic core 6 using a winding machine to produce the coil 61. The wire ends at the head and tail of the coil 61 are fixed by different wire end fixing mechanisms 5, and the wire ends are aligned with the pads of the magnetic cover 7. Specifically, the winding machine is programmed according to the product requirements. First, one wire is wound around the magnetic core 6, and its head end is clamped and fixed by one wire end fixing mechanism 5. The winding machine is then rotated to the starting position of the second wire. The second wire is pulled around the magnetic core, and its head end is clamped and fixed by another wire end fixing mechanism 5. The winding machine is started to complete the winding. Then, the tail ends of the two wires are clamped and fixed by the other two wire end fixing mechanisms 5 and the wires are cut. Depending on the needs of different products, one wire can be wound first, and then another wire can be wound. Finally, the top core 9 is removed, and the entire inductor processing device is taken off. Then, the clamping assembly 8 is installed on the main body 1 to press the magnetic core 6 onto the magnetic core carrier 2, so as to prevent the magnetic core 6 from shifting, ensure the stable and accurate position of the magnetic core 6 and the magnetic cover 7, and prevent the magnetic core 6 and the magnetic cover 7 from falling out. like Figure 13 As shown, the inductor processing device is then placed on the spot welding machine. The spot welding machine is equipped with a positioning support that matches the inductor processing device. When the inductor processing device is placed on the positioning support and positioned, the pusher 41 is automatically pushed by the positioning support, thereby causing the core carrier 2 and the magnetic cover carrier 3 to move relative to each other in the first direction. In other words, the state of the core 6 being exposed outside the magnetic cover 7 is switched to the state of the core 6 being inside the magnetic cover 7, and the wire end is connected to the pad of the magnetic cover 7. The spot welding machine is started to weld the wire end to the pad of the magnetic cover 7 through the working hole 821. Then the inductor processing device is removed from the spot welding machine, the clamping assembly 8 is removed, and the product is removed from the inductor processing device to the subsequent process.

[0035] The above are merely preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be considered as limitations on the present invention, and the scope of protection of the present invention should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
