Description
Technical Field
[0001] This utility model belongs to the technical field of winding equipment and relates to a winding mold based on a residual magnetic field iron core coil. Background Technology
[0002] With the development of urban power grids, online power grid monitoring equipment has ensured grid security and improved operation and maintenance efficiency. The power supply issue for online power grid monitoring equipment directly affects the reliability and stability of the monitoring system, and it is constantly being updated and iterated along with the development of monitoring equipment.
[0003] The latest three-core cable power harvesting device and monitoring system is a three-phase induction coil power harvesting model with three axially extending slots on the inner wall of the power harvesting magnetic core, the three slots being evenly distributed circumferentially, and protrusions forming between adjacent slots. However, due to the limitations of core space and manual winding capabilities, this has become one of the key factors restricting core winding.
[0004] Currently, most winding methods for energy harvesting coils rely on manual winding or general-purpose winding machines. Traditional manual operation requires winding enameled wire layer by layer by hand, and manually winding a coil with thousands of turns can take 2-3 hours, and is prone to errors in counting turns. While general-purpose winding machines have basic automation functions and improve winding efficiency, they require repeated adjustments to the clamp positioning for non-standard iron cores. Each time the clamp positioning needs to be adjusted due to a change in specifications, it takes more than 30 minutes of debugging, resulting in long winding times and low efficiency. Utility Model Content
[0005] The purpose of this invention is to provide a winding mold for iron core coils based on residual magnetic field, in order to solve the technical problem of low winding efficiency for non-standard iron cores. This invention improves the winding speed of non-standard iron cores while meeting their winding requirements.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] This utility model discloses a winding mold for a core coil based on residual magnetic field, comprising: a winding zone module block, wherein the winding zone module block has a winding machine mounting hole, and a first restriction zone module block and a second restriction zone module block are sleeved on the winding zone module block. The space between the winding zone module block, the first restriction zone module block and the second restriction zone module block forms a winding space, and the inner geometry and size of the winding space completely match the outer contour of the target core coil.
[0008] Furthermore, the surrounding area module block has a hexahedral structure, including a bottom surface, a top surface, two trapezoidal side surfaces, and two rectangular side surfaces;
[0009] Both the bottom and top surfaces are rectangular;
[0010] The two trapezoidal sides are identical in shape and arranged in parallel, and the two trapezoidal sides are perpendicular to the bottom and top surfaces;
[0011] The two rectangles have the same side shape;
[0012] The space between the two trapezoidal sides, the two rectangular sides, the first restricted area module block, and the second restricted area module block forms a winding space.
[0013] Furthermore, the two trapezoidal side surfaces and the two rectangular side surfaces are flat and smooth.
[0014] Furthermore, the central axis of the winding machine mounting hole is collinear with the axis of the winding space.
[0015] Furthermore, the winding machine mounting hole is a through hole formed on the winding area module block, and the winding machine mounting hole connects the bottom surface and the top surface.
[0016] Furthermore, the surrounding area module block and the first restrictive area module block are detachably and fixedly connected;
[0017] The surrounding area module block and the second restricted area module block are detachably and fixedly connected.
[0018] Furthermore, the surrounding area module block and the first restricting area module block are connected by a fixing pin, and the surrounding area module block and the first restricting area module block are provided with connecting holes for the fixing pin to pass through.
[0019] The surrounding area module block and the second restrictive area module block are connected by a fixing pin, and the surrounding area module block and the second restrictive area module block are provided with connecting holes for the fixing pin to pass through.
[0020] Furthermore, the surrounding area module block and the first restricted area module block are connected by a snap-fit connection;
[0021] The surrounding area module block and the second restricted area module block are connected by a snap-fit.
[0022] Furthermore, both the first and second restricted area modules are provided with mounting holes for the surrounding area module to pass through, and the mounting holes are in contact with the surface of the surrounding area module.
[0023] Furthermore, the sides of the first restricted area module block and the second restricted area module block that are close to each other are both cylindrical, and the space between the two cylindrical surfaces and the surrounding area module block forms a winding space.
[0024] Compared with the prior art, the present invention has the following beneficial effects:
[0025] This invention includes: a winding zone module block, a first restriction zone module block, a second restriction zone module block, and a winding machine mounting hole formed on the winding zone module block. The winding machine mounting hole allows the winding mold to be mounted on a manual winding machine for winding operations, improving winding efficiency. The winding zone module block serves as the center of the winding process, providing a stable foundation for the winding of the enameled wire. The first and second restriction zone modules, in conjunction with the winding zone module block, form a winding space that perfectly matches the outer contour of the target iron core coil to be wound. During the winding process, the enameled wire is tightly wound around the winding zone module block to form the desired iron core coil. This invention ensures that the enameled wire adheres tightly to the iron core surface during winding, ensuring that the enameled wire is wound within a specified range, and guaranteeing that the shape and size of the wound coil meet the requirements. This invention not only meets the winding requirements of non-standard iron cores but also improves the winding speed of non-standard iron cores.
[0026] This invention, through the restriction of the first restriction zone module block and the second restriction zone module block, together with the winding zone module block, forms a winding space, which can precisely limit the space for winding the iron core coil. This avoids problems such as uneven coil winding and incorrect turn count caused by human factors during manual winding, and ensures that the wound coil has stable quality and high precision.
[0027] For different specifications of iron cores, simply replace the first and second restriction zone modules of the winding zone module with different specifications to meet the winding requirements of various non-standard iron cores, thus improving the versatility and flexibility of the winding equipment.

A winding machine mounting hole 6 is a through hole formed on the winding zone module 2, allowing the winding mold to be mounted on a manual winding machine for winding operations, further improving winding efficiency. During the winding process, the enameled wire is tightly wound around the winding zone module 2, with the winding zone module 2 serving as the center of the winding, to form the desired core coil.

[0039] For different specifications of iron cores, only the first restriction zone module 3 and the second restriction zone module 4 of the winding zone module 2 need to be replaced to adapt to the winding requirements of various non-standard iron cores, thus improving the versatility and flexibility of the winding equipment. This utility model can meet the needs of rapid winding of non-standard iron cores and improve the winding speed of non-standard iron cores.
[0040] Example 1:
[0041] See Figure 1 and Figure 2 This utility model discloses a winding mold for a core coil based on residual magnetic field, comprising: a winding zone module block 2, a winding machine mounting hole 6 being a through hole formed on the winding zone module block 2, a first restriction zone module block 3 and a second restriction zone module block 4 fitted onto the winding zone module block 2, and a winding space 5 formed between the winding zone module block 2, the first restriction zone module block 3 and the second restriction zone module block 4, wherein the internal geometry and dimensions of the winding space 5 perfectly match the outer contour of the target core coil. During the winding process, enameled wire will be tightly wound around the winding zone module block 2 to form the desired core coil.

[0048] Preferred, see Figure 2 The winding area module 2 has a winding machine mounting hole 6. The central axis of the winding machine mounting hole 6 is collinear with the axis of the winding space 5, which facilitates the mounting of the winding mold on the winding machine to improve winding efficiency. In actual use, the rotating shaft of the winding machine is passed through the winding machine mounting hole 6, and the rotating shaft of the winding machine drives the winding mold to rotate for winding.
[0049] Preferably, the winding machine mounting hole 6 connects the bottom surface 201 and the top surface 202. The winding machine mounting hole 6 allows the winding mold to be mounted on a manual winding machine for winding operations, further improving winding efficiency.
[0050] Preferably, the surrounding area module 2 and the first restriction area module 3 are detachably and fixedly connected, which facilitates the quick assembly and disassembly of the surrounding area module 2 and the first restriction area module 3.
[0051] The surrounding area module 2 and the second restriction area module 4 are detachably and fixedly connected, which facilitates the quick assembly and disassembly of the surrounding area module 2 and the second restriction area module 4.
[0052] At the start of winding, the winding zone module 2 is fixedly connected to the first restrictive zone module 3, and the winding zone module 2 is fixedly connected to the second restrictive zone module 4. After winding is completed, the second restrictive zone module 4 is removed from the winding zone module 2, and then the wound coil can be removed from the winding zone module 2.
[0053] Preferred, see Figure 1The surrounding area module 2 and the first restrictive area module 3 are connected by a fixing pin 1. Both the surrounding area module 2 and the first restrictive area module 3 have communicating holes for the fixing pin 1 to pass through. (See [reference]). Figure 2 ;
[0054] The surrounding area module 2 and the second restrictive area module 4 are connected by a fixing pin 1. Both the surrounding area module 2 and the second restrictive area module 4 have communicating holes for the fixing pin 1 to pass through. (See attached image.) Figure 2 .

[0058] Preferred, see Figure 2 The first restricted area module 3 and the second restricted area module 4 are both cylindrical on the side that are close to each other, and the space between the two cylindrical surfaces and the surrounding area module 2 forms a winding space 5.
[0059] This invention ensures that the enameled wire adheres tightly to the surface of the iron core during the winding process, ensuring that the enameled wire is wound within a specified range, and guaranteeing that the shape and size of the wound coil meet the requirements. This invention not only meets the winding needs of non-standard iron cores but also improves the winding speed of non-standard iron cores.
[0060] Example 2:
[0061] See Figure 1 and Figure 2 This is a schematic diagram of the mold structure for winding an iron core coil, including a fixed module block, a winding area module block 2, a confinement area module block, and a winding machine. The following is a detailed description of this embodiment:
[0062] The fixing module includes a fixing pin 1, which consists of four thin rods. These rods secure the first restriction zone module 3, the second restriction zone module 4, and the surrounding zone module 2 into a unified whole. They pass through the restriction zone module and the surrounding zone module but do not contact the winding machine mounting holes, ensuring that while fixing the structure, they do not affect the passage of the winding machine shaft or subsequent winding operations.
[0063] Surrounding Area Module 2: See Figure 4The platform serves as a base for winding the coil. Its smooth surface provides a stable foundation for the winding of the enameled wire. During the winding process, the enameled wire is tightly wound around this platform to form the desired iron core coil.
[0064] Restricted area module, see Figure 3 It includes a first restriction zone module 3 and a second restriction zone module 4, both of which are curved baffles. The curvature of the two baffles is adapted to the contour of the target iron core. By restricting the space for winding the iron core coil, it ensures that the enameled wire is wound within a specified range, guaranteeing that the shape and size of the wound coil meet the requirements.
[0065] The connection and spatial relationship of each component:
[0066] Four thin rods of the fixed module block pass through corresponding small holes on the restricted area module block and the surrounding area module block 2, respectively, firmly connecting the two modules together. The restricted area module block is located on the periphery of the surrounding area module block, and its curved baffle fits tightly with the platform edge of the surrounding area module block to form the winding space 5. Both the restricted area module block and the surrounding area module block 2 contain through holes. The restricted area module block has mounting holes for the surrounding area module block 2 to pass through, and the surrounding area module block 2 has winding machine mounting holes 6. The axis of the mounting holes is on the same axis as the axis of the winding machine mounting holes 6. The winding machine mounting holes 6 are used to pass through the rod of the manual winding machine to ensure that the winding machine can drive the mold to rotate stably during operation.
[0067] Based on the above structure, the specific usage process of this embodiment is as follows:
[0068] Combine the molds into a single unit;
[0069] Connect it to the manual winding machine so that the shaft of the manual winding machine passes through the winding machine mounting hole 6;
[0070] One end of the enameled wire is fixed to the outside of the winding mold. The operator holds the enameled wire roller with one hand and rotates the gear of the manual winding machine with the other. As the gear rotates, the shaft of the manual winding machine drives the winding mold to rotate as well. At this time, the operator gradually releases the enameled wire, and the enameled wire will be wound onto the platform of the winding area module 2. During the winding process, the baffle of the limiting area module restricts the winding range of the enameled wire, preventing the enameled wire from winding into other areas. When the required number of turns is reached, the winding machine is stopped, the wound coil is removed from the mold, and placed onto the target iron core to complete the winding work.
[0071] Compared with the prior art, this utility model has the following advantages:
[0072] Improved winding efficiency: Compared to traditional manual winding, this new winding mold utilizes a manual winding machine, significantly increasing winding speed. Manually winding a coil with thousands of turns typically takes 2-3 hours, while using this mold to wind the same number of turns requires a substantial reduction in time, effectively saving labor and time costs.
[0073] Ensuring winding accuracy: The design of the restricted area module can precisely limit the space for winding the iron core coil, avoiding problems such as uneven coil winding and incorrect turn count caused by human factors during manual winding, thus ensuring stable quality and high precision of the wound coil.
[0074] High adaptability: Compared with general-purpose winding machines, this winding die does not require complex clamping adjustments for different specifications of iron cores. It can easily adapt to the winding needs of various non-standard iron cores by changing the limiting area module block and the winding area module block of different sizes, thus improving the versatility and flexibility of the winding equipment.
[0075] Easy to operate: This winding die has a simple structure and is easy to operate. Operators only need to install the die on the manual winding machine, fix the enameled wire, and turn the winding machine gear to perform the winding operation. No complicated training or professional skills are required, which lowers the threshold for operation.
[0076] The above content is only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of this utility model.
