[0002] Amorphous nanocrystalline ribbon, made from amorphous alloy materials, exhibits high magnetic permeability, low coercivity, and low losses, making it widely used in power electronics. It is often wound into toroidal cores to replace traditional iron-based cores. Amorphous ribbon cores offer a variety of excellent properties, including high saturation magnetic induction, low hysteresis losses, and a wide frequency response range.

[0028] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0029] The magnetic core housing device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0030] like Figure 2-Figure 6 As shown, the magnetic core shell device provided by the embodiment of the present invention includes a feeding mechanism 1 and a shell mechanism 2, wherein the feeding mechanism 1 is arranged at the feeding end of the shell mechanism 2, and a base 5 is provided at the bottom of the feeding mechanism 1 and the shell mechanism 2.

[0031] The feeding mechanism 1 includes a first feeding tube 11, a second feeding tube 12 and a magnetic core feeding tube 13, wherein the magnetic core feeding tube 13 is arranged between the first feeding tube 11 and the second feeding tube 12, the magnetic core feeding tube 13 is used for feeding the magnetic core 7, and the first feeding tube 11 and the second feeding tube 12 are used for feeding two mutually buckled protective shells 6 separately.

[0032] The shell mechanism 2 includes a shell guide tube 22, a push block 26 and a centrally inserted push rod 25, wherein the first feed pipe 11, the second feed pipe 12 and the magnetic core feed pipe 13 are all arranged on the shell guide tube 22, and a discharge pipe 33 is provided at the discharge end of the shell guide tube 22. The push blocks 26 are arranged on both sides of the interior of the shell guide tube 22. The push blocks 26 are used to squeeze and snap the two protective shells 6 together, and the centrally inserted push rod 25 passes through the push block 26.

[0033] Specifically, in the process of casing the magnetic core 7, first, two semi-circular protective shells 6 are continuously fed into the casing conduit 22 from the first feeding pipe 11 and the second feeding pipe 12, and the openings of the two protective shells 6 are made to correspond to each other. At the same time, the amorphous magnetic core 7 is continuously fed into the casing conduit 22 from the magnetic core feeding pipe 13. After the two protective shells 6 and the magnetic core 7 enter the casing conduit 22, the following is formed. Figure 4 The status shown.

[0034] Then the central penetration push rod 25 is extended and retracted to pass through the middle hole 8 of the two protective shells 6 and the magnetic core 7. At this time, the two protective shells 6 and the magnetic core 7 are centered on a straight line and can only move in a straight line along the central penetration push rod 25. Then the two protective shells 6 are pushed closer to each other by the push block 26. In the process of the protective shells 6 approaching each other, the magnetic core 7 on the same straight line is introduced into them. Finally, the push block 26 squeezes the two protective shells 6 to press and fasten each other. Since the two protective shells 6 and the magnetic core 7 are in a straight line during the movement, the deviation of the two protective shells 6 is greatly reduced during the docking process, the openings of the protective shells 6 are accurately docked, and the magnetic core 7 is accurately introduced into the protective shell 6 during the movement, reducing the failure or incomplete docking of the protective shells 6.

[0035] In one embodiment of the present invention, Figure 4 and Figure 6 As shown, a guiding rod 251 is provided on the power shaft of the central guiding push rod 25. The end of the guiding rod 251 is a tapered structure. The guiding rod 251 slides through the middle position of the push block 26. The central guiding push rod 25 is located on the center line of the casing guide tube 22.

[0036] Specifically, during the process of centering the protective shell 6 and the magnetic core 7, the centering penetration push rod 25 drives the penetration rod 251 to pass through the middle hole 8 between the protective shell 6 and the magnetic core 7. Since the end of the penetration rod 251 is a conical structure, it plays the role of a penetration guide, so that the penetration rod 251 can smoothly enter and exit the middle hole 8 between the protective shell 6 and the magnetic core 7.

[0037] It should be noted that after the protective shell 6 is covered, the central guide push rod 25 drives the guide rod 251 to retract, and the guide rod 251 leaves the protective shell 6 and the magnetic core 7, making it easier to guide the magnetic core product 9 after the cover is completed.

[0038] In one embodiment of the present invention, Figure 3 、 Figure 4 and Figure 6 As shown, the two push blocks 26 are each provided with a push block push rod 23 on the side facing away from each other, a bearing seat 242 is provided at the bottom of the push block push rod 23, a centrally inserted push rod 25 is provided on the bearing seat 242, an adjustment guide rail 24 is provided at the bottom of the bearing seat 242, and an adjustment slider 241 is provided between the bearing seat 242 and the adjustment guide rail 24.

[0039] Specifically, the movement of the push block 26 is driven by the push block push rod 23. In order to adapt to the protective shells 6 of different specifications, the position is adjusted on the adjustment guide rail 24 by adjusting the slider 241, so that the push block push rod 23 and the central threading push rod 25 can adapt to the threading position, so that the threading rod 251 has sufficient stroke and the push block 26 has sufficient stroke.

[0040] In one embodiment of the present invention, Figure 4 and Figure 5 As shown, a centering clamping assembly 21 is provided at the discharge end of the shell guide tube 22 corresponding to the first feed tube 11, the second feed tube 12 and the magnetic core feed tube 13, which is used to center the two protective shells 6 and the magnetic core 7 on the same straight line. The centering clamping assembly 21 includes a clamping shell 211, a clamping block 213 and a spring 212, wherein the clamping shell 211 is arranged on the shell guide tube 22, the clamping block 213 is slidably arranged on the inner side of the clamping shell 211, the spring 212 is arranged between the clamping block 213 and the clamping shell 211, and the clamping surface of the clamping block 213 is a wedge-shaped structure.

[0041] Specifically, during the docking process of the protective shell 6, in order to prevent the deformation of the edge of the protective shell 6 from causing docking misalignment, after the protective shell 6 enters the shell guide tube 22, the clamping block 213 elastically clamps the edge portion of the protective shell 6 so that the two edges of the protective shell 6 are fully aligned. At the same time, the clamping block 213 also clamps the edge portion of the magnetic core 7 to center the magnetic core 7 for a second time.

[0042] After the two protective shells 6 approach each other, they will contact the clamping block 213 again. The clamping block 213 aligns the edges of the protective shells 6 when they are docked, and finally fully locks the edges of the two protective shells 6. In addition, when the protective shells 6 are docked, the protective shells 6 squeeze the wedge-shaped clamping surface, elastically pushing the clamping block 213 away, without affecting the docking and locking of the protective shells 6.

[0043] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the discharge ends of the first feed tube 11, the second feed tube 12, the magnetic core feed tube 13 and the discharge tube 33 are all provided with a feeding positioning assembly 14, including a positioning pin 141 and a pin push rod 142, wherein the pin push rod 142 is respectively arranged on the discharge ends of the first feed tube 11, the second feed tube 12, the magnetic core feed tube 13 and the discharge tube 33, the positioning pin 141 is arranged on the telescopic shaft 34 of the pin push rod 142, and the positioning pin 141 corresponds to the middle hole 8 of the protective shell 6 and the magnetic core 7, and the end of the positioning pin 141 is a conical structure, which is convenient for inserting into the middle hole 8 of the protective shell 6 or the magnetic core 7.

[0044] Specifically, after the protective shell 6 and the magnetic core 7 enter the shell conduit 22, in order to prevent the protective shell 6 and the magnetic core 7 in the first feeding pipe 11, the second feeding pipe 12, and the magnetic core feeding pipe 13 from being close to each other with the protective shell 6 and the magnetic core 7 in the shell conduit 22, after the protective shell 6 and the magnetic core 7 enter the shell conduit 22, the pin push rod 142 drives the positioning pin 141 to extend, and the positioning pin 141 is inserted into the middle hole 8 of the protective shell 6 and the magnetic core 7, so that the protective shell 6 and the magnetic core 7 in the shell conduit 22 are separated from the protective shell 6 and the magnetic core 7 being fed by a certain gap, so as not to affect the docking process of the protective shell 6 and the magnetic core 7 in the shell conduit 22.

[0045] After the shell is completed, the pin push rod 142 drives the positioning pin rod 141 to retract, the protective shell 6 and the magnetic core 7 continue to feed, and the magnetic core product 9 in the shell guide tube 22 is squeezed by the magnetic core 7 and discharged to the discharge pipe 33. The pin push rod 142 in the discharge pipe 33 drives the positioning pin rod 141 to extend, positioning the magnetic core product 9 to facilitate subsequent painting work.

[0046] In one embodiment of the present invention, Figure 2 、 Figure 3 and Figure 7As shown, the discharge end of the discharge pipe 33 is provided with a shell packaging mechanism 3, which is used to apply insulating paint to the gap between the two protective shells 6 that are buckled together, including a discharge pipe 33, a telescopic push rod 31, a first paint brush 35 and a second paint brush 38, wherein the discharge pipe 33 is arranged at the discharge end of the shell guide tube 22, the telescopic push rod 31 is arranged on one side of the discharge pipe 33, a fixed tube 32 is provided between the telescopic push rod 31 and the discharge pipe 33, a telescopic shaft 34 is provided on the inner side of the fixed tube 32, the telescopic shaft 34 is connected to the output shaft of the telescopic push rod 31, the first paint brush 35 is arranged at the end of the telescopic shaft 34, and the second paint brush 38 is arranged at the bottom of the discharge pipe 33.

[0047] The distal end of the telescopic shaft 34 is tapered, and a first paint brush 36 is mounted on the inner wall of the fixed tube 32. A bottom housing 392 is located at the bottom of the discharge tube 33, and a second paint brush 38 is positioned inside the bottom housing 392. A paint brush motor 37 is mounted on one side of the bottom housing 392 to drive the second paint brush 38. A second paint brush 39 is mounted at the bottom of the second paint brush 38. A hollow protrusion is positioned at the top of the discharge tube 33 to reduce scratching during painting.

[0048] Specifically, in order to insulate and protect the gap where the two protective shells 6 are fastened to each other, after the magnetic core product 9 enters the discharge pipe 33, the first paint brush 36 is injected with insulating paint by setting a first paint injection tube 361. The insulating paint is impregnated on the first paint brush 36, and the insulating paint on the first paint brush 36 is impregnated on the first paint brush 35. As the telescopic push rod 31 drives the telescopic shaft 34 to extend, it drives the first paint brush 35 to enter the middle hole 8 of the magnetic core product 9, and then the gap at the fastening joint of the middle hole 8 of the magnetic core product 9 is painted for protection.

[0049] At the same time, the second paint brush 39 below the magnetic core product 9 is injected with insulating paint by setting a second paint injection tube 391. The insulating paint is impregnated on the second paint brush 39. The insulating paint on the second paint brush 39 is impregnated on the second paint brush 38. The second paint brush 38 is driven to rotate by the paint brush motor 37. The rotation of the second paint brush 38 drives the magnetic core product 9 to rotate, so that the outer joint gap of the magnetic core product 9 is fully painted and protected.

[0050] In one embodiment of the present invention, Figure 2 、 Figure 3 and Figure 8 As shown, the discharge end of the shell packaging mechanism 3 is provided with a sorting and discharging mechanism 4, which is used to sort and output the packaged magnetic core products 9, including a discharge tray 41, a turntable 47 and a blow-out seat 45, wherein the discharge tray 41 is arranged at the output end of the discharge pipe 33, the turntable 47 is rotatably arranged on the inner side of the discharge tray 41, a plurality of material troughs 43 are arranged on the upper surface of the turntable 47, the blow-out seat 45 is arranged in the middle position of the turntable 47, and a plurality of blowing nozzles 451 corresponding to the material troughs 43 are provided on the blow-out seat 45, and a plurality of sorting material ports 44 are provided on the edge portion of the discharge tray 41.

[0051] A rotating motor 48 is provided below the turntable 47 to drive its rotation, and a blowing control component 49 is provided at the bottom of the turntable 47, including an air supply turntable 491, an air supply main pipe 494 is provided at the air inlet end of the air supply turntable 491, and a plurality of blowing branch pipes 493 are provided at the air outlet end of the air supply turntable 491, and each blowing branch pipe 493 is provided with an electromagnetic valve 492, a supporting turntable 46 is provided at the bottom of the turntable 47, a material trough partition 42 is provided between adjacent material troughs 43, and a material receiving trough 411 is provided between the discharge tray 41 and the discharge pipe 33.

[0052] Specifically, in order to sort the magnetic core products 9 and transport them to different discharging stations, the magnetic core products 9 in the discharge pipe 33 are discharged from the receiving trough 411 and enter the turntable 47. The turntable 47 is driven to rotate by the rotating motor 48, and the magnetic core products 9 enter the trough 43 one by one. The troughs 43 are separated from each other by the trough partitions 42, so that the magnetic core products 9 are separated from each other. As the turntable 47 rotates, when the magnetic core products 9 enter different sorting ports 44, the blowing nozzle 451 on the blowing seat 45 is controlled by the solenoid valve 492 to blow air, and the magnetic core products 9 in the trough 43 are blown out from the corresponding sorting ports 44.

[0053] During the above process, the main air supply pipe 494 transmits pressurized gas to each blowing branch pipe 493 through the air supply turntable 491. Each blowing branch pipe 493 is individually controlled by the solenoid valve 492 to blow air, accurately blowing the magnetic core product 9 in the material trough 43 to the corresponding sorting material port 44, which is convenient for subsequent processing.

[0054] In order to clearly illustrate the above embodiment, refer to Figures 1-8 The working principle of the magnetic core casing device of the present invention is as follows: During the casing operation of the magnetic core 7, two semi-circular protective shells 6 are continuously fed into the casing conduit 22 through the first feeding pipe 11 and the second feeding pipe 12, and the openings of the two protective shells 6 are placed opposite each other. At the same time, the amorphous magnetic core 7 is continuously fed into the casing conduit 22 from the magnetic core feeding pipe 13. After the three enter the casing conduit 22, they form a shell as shown in FIG. Figure 4 Status shown.

[0055] After the protective shell 6 and the magnetic core 7 enter the shell guide tube 22, in order to prevent the protective shell 6 and the magnetic core 7 in the first feeding tube 11, the second feeding tube 12 and the magnetic core feeding tube 13 from being close to each other with the protective shell 6 and the magnetic core 7 in the shell guide tube 22, the pin push rod 142 pushes the positioning pin 141 to extend, and the positioning pin 141 is inserted into the middle hole 8 of the protective shell 6 and the magnetic core 7, so that a certain gap is maintained between the protective shell 6 and the magnetic core 7 in the shell guide tube 22 and the protective shell 6 and the magnetic core 7 being fed, so as not to interfere with the shell 6 and the magnetic core 7 in the shell guide tube 22 docking process.

[0056] Subsequently, the central penetration push rod 25 drives the penetration rod 251 through the middle hole 8 between the protective shell 6 and the magnetic core 7. At this time, the two protective shells 6 and the magnetic core 7 are in a straight line and can only move along the straight line of the central penetration push rod 25. Next, the push block 26 pushes the two protective shells 6 together, guiding and enclosing the magnetic core 7 on the same straight line during the process of the protective shells 6 moving together. Finally, the push block 26 squeezes the two protective shells 6 to dock and lock together.

[0057] When the shells 6 are docked, the clamping blocks 213 elastically clamp the edges of the shells 6, ensuring that the edges of the two shells 6 are fully aligned. At the same time, the clamping blocks 213 clamp the edges of the magnetic core 7 to achieve secondary centering of the magnetic core 7. When the two shells 6 are brought closer together, they will contact the clamping blocks 213 again, ensuring that the edges of the shells 6 are closely aligned and fully locked when docked.

[0058] After the protective shell 6 is wrapped around the shell, the magnetic core product 9 is formed. The magnetic core product 9 then enters the discharge pipe 33. The first paint brush 36 is filled with insulating varnish, which impregnates the first paint brush 36 and transfers to the first paint brush 35. The telescopic push rod 31 extends the telescopic shaft 34, allowing the first paint brush 35 to enter the center hole 8 of the magnetic core product 9 and apply paint to the gap at the joint of the center hole 8 of the magnetic core product 9.

[0059] At the same time, insulating varnish is injected into the second paint brush 39 below the magnetic core 9. The insulating varnish then impregnates the second paint brush 39 and is then transferred to the second paint brush 38. The second paint brush 38 is driven by the paint brush motor 37, which rotates the magnetic core 9, ensuring that the outer circumferential sidewalls of the magnetic core 9 and the joint gap between the central hole 8 are fully coated and protected.

[0060] Finally, the magnetic core products 9 in the discharge pipe 33 are discharged from the receiving trough 411 onto the turntable 47. The turntable 47 is driven by the rotary motor 48, and the magnetic core products 9 enter the trough 43 one by one. As the turntable 47 rotates, when the magnetic core products 9 enter different sorting ports 44, the blowing nozzle 451 on the blowing seat 45 blows air, blowing the magnetic core products 9 in the trough 43 out of the corresponding sorting port 44, facilitating subsequent processing.

[0061] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are exemplary and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and deform the above embodiments within the scope of the present invention.
