Abstract
Description
Technical Field
[0001] This application relates to the technical field of nanocrystalline magnetic core processing, and in particular to a nanocrystalline magnetic core impregnation and curing apparatus. Background Technology
[0002] Nanocrystalline alloys (domestic grade 1K107) have advantages such as high saturation magnetic induction, high permeability, and low loss. Therefore, nanocrystalline magnetic cores made from this nanocrystalline alloy have been widely used in common mode inductors, current transformers, transformers and other fields.
[0003] However, nanocrystalline magnetic cores become very brittle after heat treatment, making them unsuitable for subsequent processing. Traditionally, after heat treatment, nanocrystalline magnetic cores undergo a curing process. This involves immersing the core in a specially formulated adhesive for a predetermined time, then removing it and allowing it to dry completely to achieve a certain degree of resistance to deformation and toughness before automated packaging. However, current adhesive impregnation and curing processes are primarily manual, resulting in low efficiency, long processing times, and poor continuity. Utility Model Content
[0004] Therefore, it is necessary to provide a nanocrystalline magnetic core impregnation and curing device to address the problems of low efficiency, long time consumption, and poor continuity in impregnation and curing operations.
[0005] This application provides a nanocrystalline magnetic core impregnation and curing apparatus, which includes:
[0006] Controller;
[0007] A power mechanism, which is electrically connected to the controller;
[0008] A glue-impregnation tank, pre-filled with glue, is located on one side of the power mechanism, and a lifting transmission module is installed on the tank wall, the lifting transmission module being connected to the power mechanism; and
[0009] A glue-impregnated carrier plate is connected to the lifting transmission module.
[0010] This adhesive impregnation and curing device is used in the processing of nanocrystalline magnetic cores for adhesive impregnation and curing. In use, the nanocrystalline magnetic core to be impregnated is placed in the adhesive impregnation tray. The controller then sends a command to the power mechanism, which in turn sends a driving force to the lifting transmission module. This allows the lifting transmission module to lower the adhesive impregnation tray and immerse it in the adhesive, ensuring full contact between the nanocrystalline magnetic core and the adhesive, guaranteeing uniform adhesion of the adhesive to the entire outer surface of the nanocrystalline magnetic core. After a preset impregnation time, the power mechanism reverses the movement of the lifting transmission module, causing the adhesive impregnation tray to rise and be removed from the adhesive. This automatically completes the adhesive impregnation and curing process for nanocrystalline magnetic cores. Compared to the manual operation method in traditional technologies, this significantly improves processing efficiency, greatly reduces processing time, and enhances processing continuity.
[0011] The technical solution of this application will be further described below:
[0012] In one embodiment, the impregnated carrier includes a frame and a carrier body, the carrier body being disposed within the frame and used to support the nanocrystalline magnetic core.

The plurality of first carrier plates are arranged side by side at intervals along a first direction of the dipped carrier plate, and the plurality of second carrier plates are arranged side by side at intervals along a second direction of the dipped carrier plate. The first direction and the second direction intersect, such that the first carrier plates and the second carrier plates intersect to form a plurality of adhesive passage holes, and the plurality of adhesive passage holes are distributed.
[0014] In one embodiment, the carrier includes a support surface for supporting the nanocrystalline magnetic core and an adhesive surface disposed opposite to the support surface. The sides of the first carrier and the second carrier that form the support surface are both formed as arc-shaped surfaces, and the sides of the first carrier and the second carrier that form the adhesive surface are both formed as pointed conical surfaces.
[0015] In one embodiment, the lifting transmission module includes a lifting guide rail and a lifting slider. The lifting guide rail is vertically disposed on the wall of the impregnation tank, and the lifting slider is slidably disposed on the lifting guide rail. The lifting slider is connected to the power mechanism and the impregnation carrier plate via a transmission connection.
[0016] In one embodiment, the lifting slider has a hook protruding from its surface away from the lifting guide rail, and the dipped tray has a hanging hole, with the hook detachably hooked into the hanging hole.
[0017] In one embodiment, the lifting transmission module further includes an upward position sensor, which is disposed at the end of the lifting guide rail away from the adhesive. When the dip tray is aligned with the upward position sensor, it is located above the surface of the adhesive.
[0018] In one embodiment, the lifting transmission module further includes a downward position sensor, which is disposed at the other end of the lifting guide rail that extends into the adhesive. When the adhesive-impregnated carrier is aligned with the downward position sensor, it is located below the surface of the adhesive.
[0019] In one embodiment, the nanocrystalline magnetic core impregnation and curing apparatus further includes a curing rack and a transfer mechanism. The curing rack is movably disposed on one side of the impregnation tank, and the transfer mechanism is disposed between the impregnation tank and the curing rack.

However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0030] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0031] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0034] See Figure 1 This application presents an embodiment of a nanocrystalline magnetic core impregnation and curing apparatus 100, which includes a controller 10, a power mechanism 20, an impregnation tank 30, and an impregnation carrier 40.
[0035] Specifically, the controller 10 can be any of a PLC, a microcontroller, or a similar device. For example, in this application, the controller 10 uses a PLC, which offers good autonomy and controllability, and convenient and accurate instruction input and execution.
[0036] The power mechanism 20 is electrically connected to the controller 10. Thus, the rising or falling movement of the dipped carrier 40 can be automatically controlled under the command of the controller 10.
[0037] The impregnation tank 30 is pre-filled with glue and is located on one side of the power mechanism 20. A lifting transmission module 50 is installed on the tank wall of the impregnation tank 30 and is connected to the power mechanism 20. The impregnation tray 40 is connected to the lifting transmission module 50.
[0038] The impregnation tank 30 can be made of any one or more materials such as plastic and metal. The impregnation tank 30 can be an open or closed box or similar structure, which can be flexibly selected according to actual needs.
[0039] The impregnation tank 30 contains a certain amount of glue, which is used to impregnate and cure the nanocrystalline magnetic core.
[0040] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: The impregnation and curing device of this solution is applied to the processing of impregnating and curing nanocrystalline magnetic cores. In use, the nanocrystalline magnetic core to be impregnated is placed in the impregnation carrier 40. Then, the controller 10 outputs a command to the power mechanism 20, which outputs driving force to the lifting transmission module 50. This allows the lifting transmission module 50 to drive the impregnation carrier 40 to descend and sink into the glue, ensuring that the nanocrystalline magnetic core is in full contact with the glue and that the glue is evenly adhered to the entire outer surface of the nanocrystalline magnetic core. After the preset impregnation time, the power mechanism 20 drives the lifting transmission module 50 in the opposite direction to move the impregnation carrier 40 to rise and remove it from the glue. In this way, the automatic impregnation and curing process of nanocrystalline magnetic cores can be completed automatically. Compared with the manual operation method in the traditional technology, the processing efficiency is significantly improved, the processing time is greatly shortened, and the processing continuity is strong.
[0041] Please continue reading. Figure 2 In one embodiment, the impregnated carrier 40 includes a frame 41 and a carrier body 42. The carrier body 42 is disposed within the frame 41 and is used to support the nanocrystalline magnetic core. The carrier body 42 has an adhesive passage 43, which is disposed along the gravity direction and penetrates the thickness direction of the impregnated carrier 40.
[0042] The frame 41 is used to mount and fix the carrier disk 42 to improve the structural strength of the carrier disk 42, thereby improving the stability of the carrier disk 42 in supporting the nanocrystalline magnetic core. For example, the frame 41 is a circular ring, and the carrier disk 42 is connected to the annular cavity of the circular ring.
[0043] Optionally, the frame 41 and the carrier plate 42 can be integrally formed or detachable and assembled, depending on the actual needs.
[0044] When the impregnation carrier 40 and the nanocrystalline magnetic core after impregnation rise and move out of the glue together, the glue remaining in the carrier can be drained through the glue passage 43 and dripped back into the impregnation pool 30, thus avoiding glue waste and preventing the nanocrystalline magnetic core from being submerged in too much glue, which would affect the impregnation quality.
[0045] Specifically, based on the above embodiments, the carrier plate 42 includes a plurality of first carrier supports 421 and a plurality of second carrier supports 422. The plurality of first carrier supports 421 are arranged side by side at intervals along a first direction of the glue-impregnated carrier plate 40, and the plurality of second carrier supports 422 are arranged side by side at intervals along a second direction of the glue-impregnated carrier plate 40. The first direction and the second direction intersect, such that the first carrier supports 421 and the second carrier supports 422 intersect to form a plurality of glue-passing holes 43, and the plurality of glue-passing holes 43 are dispersedly arranged.
[0046] On the one hand, the use of multiple first carrier bodies 421 and multiple second carrier bodies 422 extending along the first and second directions and being staggered together simplifies the molding structure of the carrier body 42; on the other hand, the multiple adhesive passage holes 43 formed in a dispersed manner enable residual adhesive to be drained from the adhesive-impregnated carrier 40 more quickly and thoroughly, shortening the time that the adhesive-impregnated carrier 40 and the nanocrystalline magnetic core need to remain above the adhesive.
[0047] Please continue reading. Figure 3 Furthermore, the carrier body 42 includes a support surface for supporting the nanocrystalline magnetic core and a dispensing surface facing away from the support surface. The sides of the support surface formed by the first carrier body 421 and the second carrier body 422 are both formed as arc-shaped surfaces 423, and the sides of the dispensing surface formed by the first carrier body 421 and the second carrier body 422 are both formed as pointed conical surfaces 424. It is easy to understand that the formed arc-shaped surfaces 423 have a guiding effect on the residual adhesive, making it easier for the residual adhesive to flow into the dispensing hole 43; while the formed pointed conical surfaces 424 have a gathering effect on the residual adhesive flowing out of the dispensing hole 43, and the residual adhesive gathered at the pointed part of the pointed conical surface 424 is more likely to drip off under the action of gravity.
[0048] Furthermore, based on any of the above embodiments, the lifting transmission module 50 includes a lifting guide rail 51 and a lifting slider 52. The lifting guide rail 51 is vertically disposed on the wall of the impregnation tank 30, and the lifting slider 52 is slidably disposed on the lifting guide rail 51. The lifting slider 52 is connected to the power mechanism 20 and the impregnation carrier plate 40 via a transmission connection. During operation, the power mechanism 20 directly outputs lifting driving force to the lifting slider 52, and the lifting guide rail 51 guides and limits the lifting slider 52, improving the smoothness of the lifting movement of the lifting slider 52, the impregnation carrier plate 40, and the nanocrystalline magnetic core.
[0049] Preferably, there are two lifting guide rails 51 and two lifting sliders 52. The two lifting guide rails 51 are set opposite to each other on the wall of the impregnation tank 30, and the lifting sliders 52 are installed on the lifting guide rails 51 one by one. The two lifting sliders 52 are connected to the impregnation carrier 40 at the same time, thereby further improving the installation stability and movement smoothness of the impregnation carrier 40.
[0050] In this application, the power mechanism 20 includes, but is not limited to, an air compressor 21 and a cylinder 22. The air compressor 21 is connected to the cylinder 22 by pipeline. The cylinder 22 is directly connected to the lifting slider 52 or indirectly connected through an intermediate transmission medium. The air compressor 21 inflates or deflates the cylinder 22 to drive the piston rod of the cylinder 22 to move the lifting slider 52 up or down.
[0051] In one embodiment, the lifting slider 52 has a hook protruding from its surface away from the lifting guide rail 51, and the impregnated carrier 40 has a hanging hole, into which the hook can be detachably hooked. Thus, the installation method and structure of the impregnated carrier 40 and the lifting guide rail 51 are simple, and the impregnated carrier 40 can be quickly separated from the lifting guide rail 51 after the nanocrystalline magnetic core has completed the impregnation process.
[0052] Furthermore, in another embodiment, the lifting transmission module 50 also includes an upward position sensor, which is disposed at the end of the lifting guide rail 51 away from the adhesive. When the adhesive carrier 40 is aligned with the upward position sensor, it is located above the surface of the adhesive.
[0053] Similarly, the lifting transmission module 50 also includes a downward position sensor, which is located at the other end of the lifting guide rail 51 that extends into the adhesive. When the adhesive carrier 40 is aligned with the downward position sensor, it is located below the surface of the adhesive.
[0054] The upward position sensor detects the rising position of the adhesive-impregnated carrier 40, ensuring that the carrier 40 and the nanocrystalline magnetic core are completely removed from the adhesive. The downward position sensor detects the falling position of the adhesive-impregnated carrier 40, ensuring that the carrier 40 and the nanocrystalline magnetic core are completely submerged in the adhesive, thus ensuring that the adhesive impregnation operation is completed accurately, effectively, and automatically.
[0055] In actual processing, simply removing the impregnated carrier plate 40 and the impregnated nanocrystalline magnetic core and suspending them above the adhesive to allow it to cure naturally would take too long, resulting in a lengthy overall impregnation and curing process and reduced efficiency. Therefore, a more effective method is to accelerate adhesive curing through baking.
[0056] Therefore, in one embodiment, the nanocrystalline magnetic core impregnation and curing apparatus 100 further includes a curing rack and a transfer mechanism. The curing rack is movably disposed on one side of the impregnation tank 30, and the transfer mechanism is disposed between the impregnation tank 30 and the curing rack. The transfer mechanism picks up the impregnation carrier 40 and the nanocrystalline magnetic core that have been moved above the adhesive and transfers them into the curing rack. The curing rack is then moved into an oven, baked at 100°C and kept warm for half an hour. Once the adhesive is completely dry and cured, the nanocrystalline magnetic core adhesive curing operation can be completed quickly, greatly saving the adhesive curing time.
[0057] At this point, the nanocrystalline magnetic core has a certain strength and toughness, is not prone to brittleness, and is easy to process later.
[0058] Furthermore, the curing rack includes a main body and multiple shelf plates, which are arranged side-by-side and spaced apart along the height of the curing rack within the main body. Each shelf plate can hold a dip tray 40 and a nanocrystalline magnetic core. Therefore, by filling multiple shelf plates at once, multiple nanocrystalline magnetic cores can be baked and cured with adhesive simultaneously, greatly improving processing efficiency.
[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0060] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
