As shown in fig. 1, the present embodiment provides a method for manufacturing an amorphous nanocrystalline magnetic sheet, which includes the following steps:
the edge-covering material and the magnetic sheet material are alternately paved and adhered on the bearing film 10, and the edge-covering material is an insulating film, a heat dissipation film or a metal foil;
simultaneously, carrying out graphical treatment on the edge covering material and the magnetic sheet material to respectively form an edge covering structure 20 and a magnetic sheet body 30, and processing a folding line 101 on the bearing film 10, wherein the edge covering structure 20 and the magnetic sheet body 30 have the same shape, and the area of the edge covering structure 20 is larger than that of the magnetic sheet body 30;
the carrier film 10 is folded in half along the folding line 101 so that the binding structure 20 is attached to and completely covers the magnetic sheet body 30.
In the process of preparing the amorphous nanocrystalline magnetic sheet, the edge-covering material and the magnetic sheet material are generally strips, so that the edge-covering material and the magnetic sheet material can be directly paved and adhered on the bearing film 10. In this embodiment, the carrier film 10 is a PET plastic film, and the PET plastic film has a weak adhesive shape, so that the edge covering material and the magnetic sheet material can be adhered to the carrier film 10, and can be removed conveniently after the amorphous nanocrystalline magnetic sheet is processed. In addition, in the present embodiment, the edge covering material is an insulating film, a heat dissipation film, or a metal foil. When the edge-covering material is an insulating film, the insulating property of the amorphous nanocrystalline magnetic sheet can be improved. When the edge-covering material is a heat dissipation film, such as a graphite heat dissipation film, the heat dissipation performance of the amorphous nanocrystalline magnetic sheet can be improved. When the edge covering material is a metal foil, such as a copper foil and an aluminum foil, the anti-interference capability of the amorphous nanocrystalline magnetic sheet can be improved, and the signal interference, the electromagnetic interference and the like of other structures on the amorphous nanocrystalline magnetic sheet are reduced.
Because the edge covering material and the magnetic sheet material are alternately paved and adhered on the bearing film 10, namely the edge covering material and the magnetic sheet material are mutually separated, the edge covering material and the magnetic sheet material are simultaneously subjected to graphical processing to respectively form an edge covering structure 20 and a magnetic sheet body 30, a folding line 101 is processed on the bearing film 10, and the folding of the bearing film 10 at the later stage is facilitated by processing the folding line 101.
Meanwhile, the edge covering structure 20 and the magnetic sheet body 30 are the same in shape, and the area of the edge covering structure 20 is larger than that of the magnetic sheet body 30. It can be understood that the binding structure 20 can completely cover the magnetic sheet body 30 after the carrier film 10 is folded along the folding line 101, thereby achieving the binding effect on the magnetic sheet body 30.
As shown in fig. 2, the present embodiment exemplarily shows a case where the rim-covering structure 20 and the magnetic sheet body 30 are both of a square structure, and in the present embodiment, the surface area of the rim-covering structure 20 is larger than that of the magnetic sheet body 30, so that when the rim-covering structure 20 is overlaid on the magnetic sheet body 30, the distance between each side of the magnetic sheet body 30 and the corresponding side of the rim-covering structure 20 is 0.5 mm. Of course, in other embodiments, the shapes of the rim structure 20 and the magnetic sheet body 30 may also be polygonal, circular, or the like.
By the preparation method of the amorphous nanocrystalline magnetic sheet, the edge-covering material and the magnetic sheet material are alternately paved and adhered on the bearing film 10; simultaneously carrying out graphical treatment on the edge covering material and the magnetic sheet material to respectively form an edge covering structure 20 and a magnetic sheet body 30, and processing a folding line 101 on the bearing film 10, wherein the edge covering structure 20 and the magnetic sheet body 30 have the same shape, and the area of the edge covering structure 20 is larger than that of the magnetic sheet body 30; the carrier film 10 is folded in half along the pair of folding lines 101 so that the binding structure 20 is attached to and completely covers the magnetic sheet body 30. Compare in prior art, process magnetic sheet material and the material of borduring simultaneously, can avoid damaging the magnetic sheet when carrying out the cross cutting to the material of borduring, improve machining efficiency. And the bearing film 10 is folded along the folding line 101 in half, so that the edge covering structure 20 is attached to and completely covers the magnetic sheet body 30, and the attachment precision of the edge covering structure 20 and the magnetic sheet body 30 can be improved.
As shown in fig. 3 and 4, the embodiment further provides an amorphous nanocrystalline magnetic sheet manufacturing apparatus for implementing the amorphous nanocrystalline magnetic sheet manufacturing method.
The amorphous nanocrystalline magnetic sheet preparation equipment comprises a die cutting device, wherein the die cutting device comprises a first die and a second die which are respectively used for carrying out graphical treatment on a wrapping material and a magnetic sheet material, and a third die which is used for processing a folding line 101 on a bearing film 10.
The shapes of the edge covering structure 20 and the magnetic sheet body 30 which are processed by the first die and the second die respectively according to needs are set, and the embodiment is not particularly limited as long as the edge covering material and the magnetic sheet material can be subjected to graphical processing respectively. The third mold may be a cutter capable of punching the carrier film 10, and the carrier film 10 punched by the cutter has a thickness smaller than that of the carrier film 10 itself in the thickness direction of the carrier film 10, so as to form the folding line 101. Of course, the third mold may have other structures as long as the folding lines 101 can be formed on the carrier film 10.
The amorphous nanocrystalline magnetic sheet preparation equipment further comprises a folding device, wherein the folding device comprises a material conveying structure 1, a folding structure 2, a rolling structure 3 and a material receiving structure 4, the material conveying structure 1 is used for conveying the bearing film 10, the folding structure 2 is used for folding the bearing film 10, the rolling structure 3 is used for rolling the folded bearing film 10, and the material receiving structure 4 is used for rolling the folded bearing film 10.

The material receiving structure 4 comprises a material receiving shaft 41, and the carrier film 10 folded in half by the folding structure 2 is rolled up by the material receiving shaft 41. The rolling structure 3 includes two oppositely disposed rolling rollers 31, and the two rolling rollers 31 are used for rolling the folded carrier film 10. It can be understood that, under the driving of the material receiving shaft 41, the carrier film 10 passes through the two material conveying rollers 12, the folding structure 2 and the rolling structure 3 in sequence and then is wound by the material receiving shaft 41.
For convenience of description, the carrier film 10 is divided into a first part 102 and a second part 103 with respect to the folding line 101, and the binding structure 20 and the magnetic sheet body 30 are respectively located at the first part 102 and the second part 103. As shown in fig. 4, the above-mentioned folding structure 2 includes a table 21 and a guide assembly 22, the table 21 is horizontally disposed along a first direction, the first portion 102 or the second portion 103 of the carrier film 10 is located on the table 21, the first direction is a conveying direction of the carrier film 10, and the embodiment is described by taking the first portion 102 as an example located on the table 21. The guide member 22 is provided in the first direction, and the guide member 22 can fold the second portion 103 along the folding line 101 so that the second portion 103 can be attached to the first portion 102, that is, the edge-covering structure 20 and the magnetic sheet body 30 can be attached to each other.
The guide assembly 22 includes a first guide member and a second guide member spaced apart in the first direction, the first guide member being capable of guiding the second portion 103 from a horizontal state to a vertical state along the diagonal line 101, and the second guide member being capable of guiding the second portion 103 from the vertical state to the horizontal state along the diagonal line 101. The second portion 103 of the carrier film 10 conveyed horizontally can be first changed from a horizontal state to a vertical state and then from the vertical state to the horizontal state by the first guide and the second guide, that is, the second portion 103 is folded along the folding line 101.
Specifically, the first guide member includes at least two first guide structures arranged at intervals, each of the first guide structures includes a first guide platform 221 and a first guide wheel 222 arranged on the first guide platform 221 and capable of abutting against the second portion 103, and this embodiment exemplifies that two first guide structures are arranged, and two first guide wheels 222 are arranged on each of the first guide platforms 221, and it can be understood that, since the second portion 103 is to be guided to the vertical state from the horizontal state, the heights of the two first guide wheels 222 on the first guide platform 221 located in front are gradually increased along the conveying direction of the carrier film 10, so that the second portion 103 is gradually lifted upwards along the diagonal line 101 from the horizontal state and guided to the vertical state through the first guide wheels 222 on the first guide platform 221 located in rear.
The second guide member includes at least two second guide structures arranged at intervals, and the second guide structures include a second guide table 223 and a second guide wheel 224 arranged on the second guide table 223 and capable of abutting against the second portion 103.

Optionally, the folio structure 2 further includes a platen 24, the platen 24 and the table 21 forming a channel therebetween through which the first portion 102 passes. It will be appreciated that when the second portion 103 is folded, the first portion 102 is located in the channel, and the first portion 102 is always horizontal due to the obstruction of the pressure plate 24. Further, the worktable 21 is provided with a vacuum suction hole capable of sucking the first part 102 to the top surface of the worktable 21. It can be understood that the carrier film 10 is continuously moved by the material receiving shaft 41, so that the vacuum absorption only serves to stabilize the first portion 102, and does not affect the transportation of the carrier film 10.
