[0045] Example
[0046] See also Figure 1-13 The embodiment of the present invention is as follows: a nanocrystalline soft magnetic composite device comprises an installation box 1, a mounting frame 2, an active unwinding mechanism 7 and a transmission mechanism 8, wherein the active unwinding mechanism 7 comprises a mounting plate 702 rotatably mounted on the inner side of the mounting frame 2, a driving gear A703 is rotatably mounted on the center of the inner side of the mounting plate 702, a driven gear A704 is meshedly mounted on the outer side of the driving gear A703, and the driven gear A704 is rotatably mounted on the inner side of the mounting plate 702, and a driven gear A704 is fixedly mounted on one side of the driven gear A704. The clamping sleeve 711, the two driven gears A704 are clamped with a soft magnetic unwinding rod 705, a PET protective film unwinding roller 706, a release film unwinding roller 707, and two double-sided adhesive unwinding rollers 708 through the clamping sleeve 711 and the clamping rod 712, and the soft magnetic unwinding rod 705, the PET protective film unwinding roller 706, the release film unwinding roller 707, and the two double-sided adhesive unwinding rollers 708 unwind the nanocrystalline soft magnetic layer 9, the double-sided adhesive layer 901, the PET protective film layer 902, and the release film layer 903 respectively;
[0047] It should be noted that the mounting disk 702 is fixedly mounted on the inner wall of the mounting frame 2, and the rotation of the driving gear A703 drives multiple groups of driven gears A704 to rotate synchronously, and the rotating driven gear A704 drives the soft magnetic unwinding rod 705, the PET protective film unwinding roller 706, the release film unwinding roller 707, and the two double-sided adhesive unwinding rollers 708 to rotate synchronously. The synchronously rotating soft magnetic unwinding rod 705, the PET protective film unwinding roller 706, the release film unwinding roller 707, and the two double-sided adhesive unwinding rollers 708 can realize the synchronous active unwinding of the nanocrystalline soft magnetic layer 9, the double-sided adhesive layer 901, the PET protective film layer 902, and the release film layer 903. The active unwinding can reduce the traction force on the nanocrystalline soft magnetic layer 9, the double-sided adhesive layer 901, the PET protective film layer 902, and the release film layer 903 during the feeding process, thereby avoiding the problem of excessive traction on the multi-layer nanocrystalline soft magnetic layer, resulting in tensile deformation and fracture.
[0048] The mounting frame 2 has pressing mechanisms 3 rotatably mounted on both sides thereof, for pressing the nanocrystalline soft magnetic layer 9, the double-sided adhesive layer 901, the PET protective film layer 902, and the release film layer 903 to form a multi-layer nanocrystalline soft magnetic structure. The PET protective film layer 902 is attached to one side of the nanocrystalline soft magnetic layer 9 through the double-sided adhesive layer 901, and the release film layer 903 is attached to the other side of the nanocrystalline soft magnetic layer 9 through the double-sided adhesive layer 901.
[0049] The nanocrystalline soft magnetic layer 9, the double-sided adhesive layer 901, the PET protective film layer 902, and the release film layer 903 that are unwound synchronously can be synchronously pressed by a relatively rotating pressing mechanism 3. The synchronous pressing reduces the pressing steps and reduces the pressing cost. At the same time, the relatively rotating pressing mechanism 3 can feed the multi-layer nanocrystalline soft magnetic material to realize the automatic conveying, cutting, and winding of the multi-layer nanocrystalline soft magnetic material.
[0050] Two sets of deviation-correcting mechanisms 4 are fixedly installed inside the mounting frame 2, and the deviation-correcting mechanisms 4 are close to one side of the pressing mechanism 3. The deviation-correcting mechanisms 4 can correct the deviation of the composite material during the conveying process;
[0051] One group of deviation correction mechanisms 4 corrects the multi-layer nanocrystalline soft magnetic material entering the cutting mechanism 6 and the side cutting mechanism 5, thereby ensuring the position accuracy of the multi-layer nanocrystalline soft magnetic material during cutting, avoiding the cutting deviation caused by the position deviation of the multi-layer nanocrystalline soft magnetic material, and ensuring the cutting quality of the multi-layer nanocrystalline soft magnetic material;
[0052] See also Figure 7-8 A reeling frame 201 is rotatably mounted on one side of the mounting frame 2, a cutting mechanism 6 is fixedly mounted on the top of the mounting frame 2, and a side cutting mechanism 5 is penetrated and installed on one side of the mounting frame 2 near the cutting mechanism 6. The composite material is cut by the side cutting mechanism 5 and the cutting mechanism 6, and the cut composite material is reeled by the reeling frame 201;
[0053] Among them, the cutting mechanism 6 includes an encoder, which is electrically connected to the controller 104 through a wire. When the composite material passes through the cutting mechanism 6, the encoder measures the length of the transported composite material. The side cutting mechanism 5 includes a bidirectional screw, a wire sleeve, and a cutting disk sleeved on the outside of the wire sleeve. The bidirectional screw and the wire sleeve are rotated to drive the cutting disk to move relatively. The relatively moving cutting disk can be adjusted according to the actual cutting width of the multi-layer nanocrystalline soft magnetic material. The adjusted cutting disk can trim the transported and moving multi-layer nanocrystalline soft magnetic material. After the trimming is completed, the multi-layer nanocrystalline soft magnetic material is cut off by the cutting mechanism 6, which is convenient for controlling the winding length of the multi-layer nanocrystalline soft magnetic material.
[0054] The transmission mechanism 8 is rotatably mounted on the back of the mounting frame 2, and the transmission mechanism 8 drives the winding frame 201, the two sets of pressing mechanisms 3, and the active unwinding mechanism 7 to rotate synchronously, thereby realizing the synchronous operation of unwinding, pressing, and winding;
[0055] It should be noted that the movement of the transmission mechanism 8 can simultaneously drive the winding frame 201, two sets of pressing mechanisms 3, and the active unwinding mechanism 7, so that the device can synchronously unwind, press and wind up the multi-layer nanocrystalline soft magnetic material, thereby improving the composite processing efficiency of the multi-layer nanocrystalline soft magnetic material and reducing energy consumption.
[0056] See also Figure 9-12 A mounting tube 701 is fixedly installed between the two driving gears A703, a bidirectional screw rod B710 penetrating the mounting plate 702 is rotatably installed inside the mounting tube 701, and a material blocking plate 709 is installed on the outer side of the bidirectional screw rod B710 through a thread sleeve;
[0057] It should be noted that the two driving gears A703 can be driven to rotate synchronously through the mounting tube 701, and the synchronously rotating driving gear A703 can drive the meshing driven gear A704 to rotate on its own. The rotating driven gear A704 drives the soft magnetic unwinding rod 705, the PET protective film unwinding roller 706, the release film unwinding roller 707, and the two double-sided adhesive unwinding rollers 708 to rotate synchronously through the clamping sleeve 711 and the clamping rod 712. The bidirectional lead screw B710 passes through the front of the mounting frame 2 and is fixedly installed with a knob. The bidirectional lead screw B710 is rotated by holding the knob and cooperates with the thread sleeve to drive the two sets of material blocking disks 709 to move relative to each other. The relatively moving material blocking disks 709 can limit the two ends of the coil to ensure that the coil remains stable during unwinding.
[0058] See also Figure 11-12 The clamping rod 712 includes a telescopic spring 7121 fixedly mounted on both ends of the soft magnetic unwinding rod 705, and both ends of the soft magnetic unwinding rod 705 are movably sleeved with a telescopic latch 7122, and the interior of the telescopic latch 7122 is fixedly connected to one end of the telescopic spring 7121;
[0059] It should be noted that both ends of the winding frame 201, the PET protective film unwinding roller 706, the release film unwinding roller 707 and the two double-sided tape unwinding rollers 708 are all equipped with clamping rods 712. Therefore, the winding frame 201, the soft magnetic unwinding rod 705, the PET protective film unwinding roller 706, the release film unwinding roller 707 and the two double-sided tape unwinding rollers 708 can all be disassembled and assembled to facilitate the loading of the coiled material. The telescopic pin 7122 is extended to the clamping sleeve 711 through the reset force of the telescopic spring 7121 for clamping.
[0060] See also Figure 4-5 The pressing mechanism 3 includes a chute tube 301, and side plates 302 are fixedly installed at both ends of the chute tube 301. One side of the side plate 302 is fixedly connected to the transmission mechanism 8. A bidirectional screw rod A303 is rotatably installed inside the chute tube 301. Two groups of thread sleeve shaft frames 304 are sleeved on the outer side of the bidirectional screw rod A303. A cross frame 305 is installed on the outer side of the two groups of thread sleeve shaft frames 304 through axle bolts. A pressing arc plate 306 is installed at one end of the cross frame 305 through axle bolts.
[0061] It should be noted that the two side plates 302 are rotatably installed on the inner wall of the mounting frame 2 at opposite sides thereof, and a knob which passes through the front of the mounting frame 2 is fixedly installed at one end of the bidirectional screw rod A303. The bidirectional screw rod A303 is rotated by the knob to drive the two groups of thread sleeve shaft frames 304 to move relative to each other. The relatively moving thread sleeve shaft frames 304 drive the cross frame 305 to expand and move, thereby driving the pressing arc plate 306 to expand outward, thereby expanding the diameter of the two groups of pressing mechanisms 3. The distance between the two groups of pressing mechanisms 3 is adjusted by adjusting the diameter of the pressing mechanism 3, so that the pressing force of the pressing mechanism 3 on the material can be adjusted according to the pressing needs.

A spiral convex roller 407 is installed through the adjusting gear 406, and a thread groove meshing with the spiral convex roller 407 is opened inside. A coupling rod 408 is installed at one end of the spiral convex roller 407 through an axle bolt, and a shaft arm 409 is installed at the other end of the coupling rod 408 through an axle bolt. A transmission rod 411 is fixedly installed at the other end of the shaft arm 409, and a servo motor 410 is fixedly installed at the other end of the transmission rod 411. A protective tube 412 is sleeved on the outer side of the transmission rod 411, and one end of the protective tube 412 is fixedly installed on the inner wall of the mounting frame 2;
[0063] It should be noted that the transmission rod 411 is safely protected by the protective tube 412 to prevent the transmission rod 411 from being entangled with foreign objects. The servo motor 410 is powered on to drive the shaft arm 409 to rotate through the transmission rod 411. The rotating shaft arm 409 drives the spiral convex roller 407 to move back and forth horizontally through the coupling rod 408. The horizontally reciprocating spiral convex roller 407 drives the adjustment gear 406 to rotate forward and reversely using the thread groove. The forward and reverse rotating adjustment gear 406 drives the adjustment seat 402 to move back and forth in the horizontal direction through the meshing adjustment rack 405. The horizontally moving adjustment seat 402 adjusts the multi-layer nanocrystalline soft magnetic material through the adjustment roller 403 and the guide roller 404 to correct the deviation.

[0070] A nanocrystalline soft magnetic composite process comprises the following steps:
[0071] Step 1: Check the device before starting up. After checking that the surrounding conditions of the device meet the operating conditions, turn on the power of the device, and drive the winding frame 201, the two sets of pressing mechanisms 3, and the active unwinding mechanism 7 to operate synchronously by turning on the transmission mechanism 8;
[0072] Specifically, the driving motor 801 drives the pulley group B803 to rotate synchronously through the pulley group A802, and the synchronously rotating pulley group B803 drives the two pulley groups C804 and the driving gear B805 to rotate synchronously, and the rotating driving gear B805 drives the two pressing mechanisms 3 to rotate relative to each other through the meshing driven gear B806, and the two relatively rotating pressing mechanisms 3 can press and convey the materials;
[0073] Step 2: Pull out the telescopic pin 7122 and move it out of the card sleeve 711, move the telescopic pin 7122 to compress the telescopic spring 7121, and remove the soft magnetic unwinding rod 705, the PET protective film unwinding roller 706, the release film unwinding roller 707, and the two double-sided adhesive unwinding rollers 708, and sleeve the tape-shaped nanocrystalline soft magnetic layer 9 on the outside of the soft magnetic unwinding rod 705, and sleeve the tape-shaped double-sided adhesive layer 901 on the outside of the two double-sided adhesive unwinding rollers 708, respectively, and sleeve the tape-shaped PET protective film layer 902 on the outside of the PET protective film unwinding roller 706, and sleeve the tape-shaped release film layer 903 on the outside of the release film unwinding roller 707, and the double-sided adhesive layer 901 is respectively located on both sides of the nanocrystalline soft magnetic layer 9, and the PET protective film layer 902 and the release film layer 903 are respectively located on the opposite sides of the double-sided adhesive layer 901;
[0074] Specifically, a group of pulley groups C804 drives the driving gear A703 to rotate, and the rotating driving gear A703 drives multiple groups of driven gears A704 to rotate synchronously, and the rotating driven gear A704 drives the soft magnetic unwinding rod 705, the PET protective film unwinding roller 706, the release film unwinding roller 707, and the two double-sided adhesive unwinding rollers 708 to rotate synchronously. The synchronously rotating soft magnetic unwinding rod 705, the PET protective film unwinding roller 706, the release film unwinding roller 707, and the two double-sided adhesive unwinding rollers 708 can realize the synchronous active unwinding of the nanocrystalline soft magnetic layer 9, the double-sided adhesive layer 901, the PET protective film layer 902, and the release film layer 903. The active unwinding can reduce the traction force on the nanocrystalline soft magnetic layer 9, the double-sided adhesive layer 901, the PET protective film layer 902, and the release film layer 903 during the feeding process;
[0075] Step 3: Pull the composite material of the nanocrystalline soft magnetic layer 9, the double-sided adhesive layer 901, the PET protective film layer 902, and the release film layer 903 to between the two sets of pressing mechanisms 3 on one side of the active unwinding mechanism 7, and adjust the distance between the two sets of pressing mechanisms 3 according to the pressing force required;
[0076] Specifically, the two-way screw rod A303 is rotated by the knob to drive the two sets of wire sleeve shaft frames 304 to move relative to each other, and the relatively moving wire sleeve shaft frames 304 drive the cross frame 305 to expand and move, thereby driving the pressing arc plate 306 to expand outward, expanding the diameter of the two sets of pressing mechanisms 3, and adjusting the distance between the two sets of pressing mechanisms 3 by adjusting the diameter of the pressing mechanism 3, adjusting the pressing distance by adjusting the distance between the two sets of pressing mechanisms 3, and adjusting the pressing force by adjusting the pressing distance, and the first pressing and conveying of the material is performed by the two sets of relatively rotating pressing mechanisms 3;
[0077] Step 4: The pressed composite material is pulled and conveyed to the deviation correction mechanism 4, and the deviation of the composite material conveying is monitored by the deviation sensor 203. The deviation sensor 203 transmits the monitoring electrical signal to the controller 104 for calculation, and the deviation correction mechanism 4 is controlled according to the calculation structure of the controller 104 to correct the position of the composite material;
[0078] Specifically, the servo motor 410 is powered on and drives the shaft arm 409 to rotate through the transmission rod 411. The rotating shaft arm 409 drives the spiral convex roller 407 to move back and forth horizontally through the coupling rod 408. The spiral convex roller 407 that moves back and forth horizontally drives the adjustment gear 406 to rotate forward and reversely by using the thread groove. The adjustment gear 406 that rotates forward and reversely drives the adjustment seat 402 to move back and forth in the horizontal direction through the meshing adjustment rack 405. The horizontally movable adjustment seat 402 adjusts the multi-layer nanocrystalline soft magnetic material through the adjustment roller 403 and the guide roller 404 to correct the deviation, so as to realize the correction adjustment before cutting and ensure the accuracy of the composite material during cutting.
[0079] Step 5: The composite material after deflection correction is pulled to the cutting mechanism 6 and the side cutting mechanism 5, and the side edge of the composite material is cut by the side cutting mechanism 5, and then the conveying length of the composite material after the edge cutting is monitored by the encoder in the cutting mechanism 6, and the monitoring electrical signal is transmitted to the controller 104. When the length set by the controller 104 is reached, the cutting mechanism 6 is controlled to cut the composite material, and the winding length of the composite material is controlled, and the cut waste is conveyed to the storage box 101 through the collecting hopper 102 for storage;
[0080] Step 6: The cut composite material is pulled to another set of deflection correction mechanism 4, and after deflection correction, it is pressed for the second time by another set of pressing mechanism 3, and the pressed composite material is rolled up by the winding frame 201;
[0081] Specifically, another group of pulleys C804 drives the reel-up frame 201 to rotate, and the rotating reel-up frame 201 can reel up the secondary pressed composite material.
[0082] A multilayer nanocrystalline soft magnetic structure, comprising a nanocrystalline soft magnetic layer 9 and double-sided adhesive layers 901 respectively located on both sides of the nanocrystalline soft magnetic layer 9, and also comprising a PET protective film layer 902 and a release film layer 903 respectively located on opposite sides of the double-sided adhesive layer 901, the PET protective film layer 902 is adhered to the upper side of the nanocrystalline soft magnetic layer 9 through the double-sided adhesive layer 901, the surface of the PET protective film layer 902 is sprayed with a polymer coating of paraxylene, and the release film layer 903 is adhered to the lower side of the nanocrystalline soft magnetic layer 9 through the double-sided adhesive layer 901;
[0083] Specifically, the polymer coating of p-xylene can be prefabricated and coated on the surface of the PET protective film layer 902 under a vacuum environment, and a conformal coating with uniform thickness is formed by vapor deposition polymerization (VDP) technology, and the thickness can be controlled to be less than 1 micron. Parylene is a polymer of p-xylene, and has excellent physical and electrical properties, such as high insulation, low dielectric loss, high dielectric strength and good mechanical properties. The polymer coating of p-xylene can effectively prevent corrosion caused by moisture, while increasing the strength and insulation performance of the material;
[0084] The PET protective film layer 902 is adhered to the surface of the nanocrystalline soft magnetic layer 9 through the double-sided adhesive layer 901, which can isolate the air to prevent the nanocrystalline soft magnetic layer 9 from reacting with oxygen, moisture, etc. in the air, thereby maintaining the stability of the magnetic properties of the nanocrystalline soft magnetic layer 9. The PET protective film layer 902 can also be used to mechanically protect the nanocrystalline soft magnetic layer 9 to prevent physical damage. At the same time, the PET protective film layer 902 has good flexibility, and can also increase the tensile toughness of the nanocrystalline soft magnetic layer 9 and improve the fracture resistance of the nanocrystalline soft magnetic layer 9.
[0085] The release film layer 903 can protect the nanocrystalline soft magnetic layer 9 when it is not in use, so as to prevent the double-sided adhesive layer 901 on one side of the nanocrystalline soft magnetic layer 9 from sticking to dust and affecting the subsequent adhesion effect. The double-sided adhesive layer 901 facilitates the PET protective film layer 902 and the release film layer 903 to adhere to the two sides of the nanocrystalline soft magnetic layer 9. At the same time, the nanocrystalline soft magnetic layer 9 peels off the release film layer 903, and the nanocrystalline soft magnetic layer 9 is adhered to the device structure through the double-sided adhesive layer 901.
[0086] The physical stability and chemical stability of the material can be increased by the PET protective film layer 902 and the release film layer 903 structure. Since the PET protective film layer 902 and the release film layer 903 protect the nanocrystalline soft magnetic layer 9, the nanocrystalline soft magnetic layer 9 can maintain good magnetic stability when affected by external factors.
