Detailed Embodiment

[0027] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts fall within the protection scope of the present invention.

[0028] The following combines Figures 1 - 10 to describe the laminating device and laminating method of the amorphous motor iron core of the present invention.

[0029] As Figure 1 shown, in the embodiment of the present invention, the laminating device of the amorphous motor iron core includes: a pair of plate bodies 10, a plurality of positioning posts 20, a plurality of fasteners 30 and a plurality of positioning members. The pair of plate bodies 10 are arranged in parallel, and the plurality of positioning posts 20 are arranged between the pair of plate bodies 10. In this embodiment, each positioning post 20 is a hollow structure, and its inner wall is provided with internal threads. The number of positioning posts 20 is 4. Each fastener 30 penetrates the plate body 10 and is threadedly connected to the positioning post 20. At least one plate body 10 is provided with a third through hole, and the inner diameter of the third through hole is equal to the inner diameter of the positioning post 20. A plurality of layers of amorphous alloy sheets 100 are arranged between the pair of plate bodies 10. When the fastener 30 and the positioning post 20 are fastened, the pair of plate bodies 10 can press the plurality of layers of amorphous alloy sheets 100 tightly.

[0030] In this embodiment, the production method of the amorphous motor iron core is as follows: after stacking the stamped amorphous alloy sheets 100, the whole is impregnated with glue. The plate body 10 is a profiling plate body, and a plurality of positioning holes are provided on each plate body 10. The amorphous alloy sheet 100 is provided with a plurality of first through holes, and the plurality of positioning holes are arranged in one-to-one correspondence with the plurality of first through holes. In this embodiment, the arrangement of the plurality of positioning holes in one-to-one correspondence with the plurality of first through holes means that the shapes and positions of the positioning holes and the corresponding first through holes are the same. When arranging multiple layers of amorphous alloy sheets 100 on one plate body 10, the positioning member is used to position the amorphous alloy sheets 100 to prevent the position from shifting when multiple layers of amorphous alloy sheets 100 are stacked. After pressing multiple layers of amorphous alloy sheets 100 between a pair of plate bodies 10, the positioning member is taken out, and the pressed integral structure is put into an impregnation device for impregnation. By adopting the method of integral impregnation, the uniformity of the glue adhering to the surface of the amorphous alloy sheet can be improved, thereby ensuring the adhesive force of the glue. Compared with dot gluing, the bonding efficiency and the stability after bonding are greatly improved.

[0031] For the convenience of description, the plate body 10 located below the multiple layers of amorphous alloy sheets 100 is called the lower plate body, and the plate body 10 located above the multiple layers of amorphous alloy sheets 100 is called the upper plate body. In the embodiment of the present invention, optionally, the positioning column 20 can be fixedly connected to the lower plate body; optionally, grooves can also be provided on the surfaces of the upper plate body and the lower plate body, and both ends of the positioning column 20 are respectively embedded in the grooves. The shape of the groove can be polygonal. Correspondingly, the shape of the positioning column 20 matches the shape of the groove to prevent the positioning column 20 from rotating when the fastener 30 is connected to the positioning column 20, so as to avoid damaging the amorphous motor iron core. In this embodiment, the height of the positioning column 20 outside the two plate bodies 10 is the target height after stacking the multiple layers of amorphous alloy sheets, so that the heights of the amorphous motor iron cores produced in batches are consistent, ensuring the consistency of the height after stacking. Further, grooves can also be provided only on the surface of the lower plate body, and one end of the positioning column 20 is embedded in the groove to prevent the positioning column 20 from rotating when the fastener 30 is connected to the positioning column 20, and at the same time, it is convenient to disassemble the upper plate body, improving the efficiency during the continuous production of the amorphous motor iron core.

[0032] The stacking device of the amorphous motor iron core provided by the embodiment of the present invention can press multiple layers of amorphous alloy sheets by arranging a pair of plate bodies, a plurality of positioning columns and a plurality of fasteners, improving the stacking coefficient of the multiple layers of amorphous alloy sheets. The stacking coefficient of the output product is ≥92%, thereby improving the strength of the amorphous motor iron core; and it can ensure the consistency of the stacking coefficient and the height of the amorphous motor iron cores produced in batches; at the same time, using this stacking device can also prevent warping of the teeth and yokes of the amorphous motor iron core during the production process, effectively protecting the integrity of the structure of the amorphous motor iron core.

[0033] Further, in the embodiments of the present invention, on the surface where each plate body 10 is stacked with the amorphous alloy sheet 100, there are profiling bumps 14, and the shape of the profiling bumps 14 is the same as that of the amorphous alloy sheet 100. Multiple layers of amorphous alloy sheets 100 are stacked between a pair of profiling bumps 14. The advantages of setting the profiling bumps 14 are as follows: on the one hand, it can increase the strength of the plate body 10, facilitate the edge trimming and shaping of the outer contour during the assembly of the amorphous alloy sheet 100, and improve the dimensional accuracy of the product; on the other hand, it is convenient to spray a release agent on the part in contact with the amorphous alloy sheet 100 before production. After the amorphous alloy sheet 100 is impregnated and cured, it is easy to separate from the stacking device, avoiding the strong adhesion between the amorphous alloy sheet 100 and the stacking device and making it difficult to remove.

[0034] In the embodiments of the present invention, a fastener 30 penetrates through the upper plate body and is threadedly connected to one end of the positioning post 20, and another fastener 30 penetrates through the lower plate body and is threadedly connected to the other end of the positioning post 20. During installation, first connect the lower plate body with the positioning post 20. Since one end of the positioning post 20 has been threadedly locked with the fastener 30, when the fastener 30 is threadedly connected to the other end of the positioning post 20, the positioning post 20 will not rotate. On the one hand, it can prevent the amorphous alloy sheet from being damaged when the positioning post 20 rotates, and on the other hand, it can ensure that the upper plate body abuts against the positioning post 20 to stack multiple layers of amorphous alloy sheets 100 to the target height. Threadedly connecting both ends of the positioning post 20 with the fastener 30 facilitates the disassembly and replacement of the positioning post 20, so as to use a set of stacking device to achieve different stacking heights. Further, the third through hole on the lower plate body is a stepped hole, and the fastener 30 is embedded in the stepped hole and threadedly connected to the positioning post 20 to make the surface of the lower plate body flat. Optionally, the fastener 30 can be a bolt, and most of the rod body of the bolt is located inside the positioning post 20, and the remaining part of the rod body and the nut are located inside the stepped hole.

[0035] As Figure 2 shown, in the embodiments of the present invention, the multiple positioning holes include a first positioning hole 11, and the first positioning hole 11 is provided at the center of the plate body 10. The multiple positioning members include a first positioning member 40, and the first positioning member 40 passes through the first positioning hole 11.

[0036] Specifically, during actual operation, as Figure 2 shown, first connect the positioning post 20 with the lower plate body through the fastener 30, and multiple positioning posts 20 are located above the lower plate body. As Figure 3 shown, insert the first positioning member 40 into the first positioning hole 11 of the lower plate body, and sequentially sleeved multiple layers of amorphous alloy sheets 100 outside the first positioning member 40 to make the multiple layers of amorphous alloy sheets 100 coaxial.

[0037] As Figure 1As shown, the multiple positioning holes further include a plurality of second positioning holes 12, and the plurality of second positioning holes 12 are arranged in a circumferential ring along the periphery of the plate body 10. The multiple positioning members further include a plurality of second positioning members 50, and each second positioning member 50 is inserted into one of the second positioning holes 12.

[0038] Specifically, before sleeving the multi-layer amorphous alloy sheets 100 outside the first positioning member 40, as Figure 4 shown, the multi-layer amorphous alloy sheets 100 can be stacked first, and then the plurality of second positioning members 50 are respectively inserted into the first through holes correspondingly arranged on the amorphous alloy sheets 100, and the multi-layer amorphous alloy sheets are threaded through as a whole by the plurality of second positioning members 50. After that, as Figure 5 shown, the multi-layer amorphous alloy sheets are further sleeved outside the first positioning member 40, and the second positioning member 50 is inserted into the second positioning hole 12 of the lower plate body. At this time, not only can the coaxial setting of the multi-layer amorphous alloy sheets 100 be ensured, but also the relative positions between the multi-layer amorphous alloy sheets 100 will not deviate greatly. After that, the upper plate body is arranged on the multi-layer amorphous alloy sheets 100. At this time, the first positioning member 40 passes through the first positioning hole of the upper plate body, and the second positioning member 50 passes through the second positioning hole 12 of the upper plate body. The fastener 30 is threadedly connected to the positioning post 20 and tightened. After that, the first positioning member 40 and the second positioning member 50 are taken out, and the remaining overall structure is put into a dipping device for dipping.

[0039] Optionally, in the embodiment of the present invention, the second positioning holes 12 are arranged at the four corners of the plate body 10, so the number of the second positioning holes 12 is 4. The number of the second positioning members 50 can be 4, that is, one second positioning member 50 is inserted into each second positioning hole 12; the number of the second positioning members 50 can also be 2, and the second positioning members 50 are only inserted into the second positioning holes 12 in the diagonal direction of the plate body 10.

[0040] Further, the shape of the second positioning member 50 can be a smooth shaft. At this time, when installing the upper plate body, it is not necessary to draw out the second positioning member 50 from the second positioning hole 12, and the second positioning hole 12 on the upper plate body can be directly passed through the second positioning member 50; when the shape of the second positioning member 50 is a stepped shaft, that is, the second positioning member 50 includes two rod bodies with different diameters, and the rod body with a smaller diameter is inserted into the multi-layer amorphous alloy sheets 100. At this time, the upper pressing plate cannot pass through the stepped shaft. Then, when installing the upper plate body, the second positioning member 50 can be drawn out first, and after the upper plate body is placed on the multi-layer amorphous alloy sheets 100 and the fastener 30 is pre-tightened, the second positioning member 50 is inserted into the second positioning hole 12 and the first through hole of the multi-layer amorphous alloy sheets 100 to prevent the multi-layer amorphous alloy sheets 100 from shifting when the fastener 30 is tightened. Further, setting the second positioning member 50 as a stepped shaft is beneficial to drawing out the second positioning member 50 from the second positioning hole 12.

[0041] As shown Figure 1 in the figure, the plurality of positioning holes further include a plurality of third positioning holes 13, the plurality of third positioning holes 13 are arranged in a circumferential ring along the circumference of the plate body 10, and the plurality of third positioning holes 13 are located between the first positioning hole and the second positioning hole 12. In this embodiment, the third positioning hole 13 is a trapezoidal hole. The plurality of positioning members further include a plurality of third positioning members 60, and each third positioning member 60 is inserted into one of the third positioning holes 13. In this embodiment, the number of the third positioning members 60 may be equal to the number of the third positioning holes 13, or the number of the third positioning members 60 may be less than the number of the third positioning holes 13, that is, the third positioning members 60 are only inserted into some of the third positioning holes 13. The shape of the third positioning member 60 matches the shape of the third positioning hole 13.

[0042] In actual use, after the multi-layer amorphous alloy sheets 100 are sleeved outside the first positioning member 40, as Figure 6 shown in the figure, the third positioning members 60 are inserted into the first through holes corresponding to the third positioning holes 13 on the amorphous alloy sheets 100 and the third positioning holes 13 of the lower plate body. After that, as Figure 7 shown in the figure, the upper plate body is then arranged on the multi-layer amorphous alloy sheets 100, and the third positioning members 60 pass through the third positioning holes 13 of the upper plate body.

[0043] As Figure 4 shown in the figure, the stacking device of the amorphous motor core further includes a pair of end plates 70, and the pair of end plates 70 are respectively stacked on the upper and lower surfaces of the multi-layer amorphous alloy sheets 100 and are attached to the profiling bumps 14 of the plate body 10. During installation, the two end plates 70 are first arranged on both sides of the multi-layer amorphous alloy sheets 100, and then the multi-layer amorphous alloy sheets 100 are connected into a whole by using the second positioning members 50. In this embodiment, the shape of the end plate 70 matches the shape of the amorphous alloy sheet 100, and the dimensions of the grooves and holes on the end plate 70 may be equal to or slightly larger than the dimensions of the grooves and holes on the amorphous alloy sheet 100, such as between 0 mm and 1 mm; the outer contour dimensions of the end plate 70 may be equal to or slightly smaller than the dimensions of the amorphous alloy sheet 100, such as between 0 mm and 1 mm. When the profiling bumps 14 are provided on the pair of plate bodies 10 and the pair of end plates 70 are provided between the pair of plate bodies 10, the sum of the target height after the multi-layer amorphous alloy sheets 100 are stacked, the thickness of the pair of end plates 70, and the thickness of the pair of profiling bumps 14 is the length of the positioning column 20 located between the pair of plate bodies 10.

[0044] As Figure 1 shown in the figure, in the embodiment of the present invention, the stacking device of the amorphous motor core further includes a pull ring 41, the pull ring 41 is connected to the first positioning member 40, and when the pull ring 41 is pulled, the first positioning member 40 can be withdrawn from the first positioning holes of the lower plate body and the upper plate body.

[0045] like Figure 1 As shown, in an embodiment of the present invention, the positioning column 20 is a hollow structure, and a plurality of second through holes 21 penetrating the wall of the positioning column 20 are provided on the surface of the positioning column 20, and the second through holes 21 are used to discharge the glue in the positioning column 20 after dipping.

[0046] The present invention also provides a lamination method for an amorphous motor core, which specifically comprises the following steps: Step 101: Connect multiple positioning columns 20 to a plate body 10, and insert the first positioning member 40 into the first positioning hole of the plate body 10; Step 102: Sleeve the multi-layer amorphous alloy sheet outside the first positioning member 40, and insert the remaining positioning members into the corresponding positioning holes; Step 103: Place another plate body 10 on the multi-layer amorphous alloy sheet 100, connect the fastener 30 with the positioning column 20, and tighten the fastener 30 so that the plate body 10 located above the multi-layer amorphous alloy sheet 100 abuts against the positioning column 20.

[0047] Specifically, if Figure 2 As shown, the positioning posts 20 are first connected to the lower plate body by fasteners 30, and a plurality of positioning posts 20 are located above the lower plate body. Figure 3 As shown, the first positioning member 40 is inserted into the first positioning hole of the lower plate body, and the multi-layer amorphous alloy sheet 100 is sequentially sleeved outside the first positioning member 40 so that the multi-layer amorphous alloy sheet 100 is arranged coaxially. The remaining positioning members are inserted into the corresponding positioning holes through the amorphous alloy sheet 100 to avoid positional displacement between the multi-layer amorphous alloy sheets 100. The upper plate body is placed on the multi-layer amorphous alloy sheet 100, and the positioning member penetrates the multi-layer amorphous alloy sheet 100. At this time, the height of the multi-layer amorphous alloy sheet 100 is greater than the height of the positioning column 20. The fastener 30 and the positioning column 20 are tightened until the upper plate body abuts against the positioning column 20. At this time, the height of the multi-layer amorphous alloy sheet 100 is the target height. After tightening, take out all the positioning members, and put the stacking device into the dipping device for dipping, so that the multi-layer amorphous alloy sheet 100 is evenly bonded.

[0048] The stacking method of the amorphous motor core provided in the embodiment of the present invention can stack multiple layers of amorphous alloy sheets to a target height, thereby improving the stacking coefficient of the multiple layers of amorphous alloy sheets, ensuring the consistency of the stacking coefficient and height of the mass-produced amorphous motor cores, and improving the strength of the amorphous motor cores.

[0049] like Figure 4 As shown, in an embodiment of the present invention, the step of inserting the remaining positioning members into the corresponding positioning holes includes: before the multi-layer amorphous alloy sheet 100 is sleeved on the first positioning member 40, the second positioning member 50 is inserted into the multi-layer amorphous alloy sheet 100 to form the multi-layer amorphous alloy sheet 100 as a whole, and then, as shown in FIG. Figure 5As shown, the multi-layer amorphous alloy sheets 100 are then sleeved outside the first positioning member 40.

[0050] Before passing the second positioning member 50 through the multi-layer amorphous alloy sheets 100, a pair of end plates 70 are respectively placed on both sides of the multi-layer amorphous alloy sheets 100. Then, the second positioning member 50 is passed through the end plates 70 and the multi-layer amorphous alloy sheets 100 so that the end plates 70 and the multi-layer amorphous alloy sheets 100 form an integral body.

[0051] In the embodiment of the present invention, the step of inserting the remaining positioning members into the corresponding positioning holes further includes: as Figure 6 shown, after sleeving the multi-layer amorphous alloy sheets 100 outside the first positioning member 40, the third positioning member 60 is passed through the amorphous alloy sheets 100 and inserted into the third positioning hole 13 of the lower plate body. In this embodiment, since the second positioning member 50 is a stepped shaft, the diameter of the end with the larger diameter of the stepped shaft exceeds the diameter of the first through hole corresponding to the second positioning hole 12 on the upper plate body. Therefore, when installing the upper plate body, the second positioning member 50 is first pulled out. As Figure 7 shown, the upper plate body is passed through the first positioning member 40 and the third positioning member 60 and placed on the end plate 70. At this time, the height of the multi-layer amorphous alloy sheets 100 is greater than the height of the positioning posts 20. The fasteners 30 are screwed into the positioning posts 20 for pre-tightening. Then, as Figure 8 shown, the second positioning member 50 is inserted into the second positioning holes 12 of the upper plate body and the lower plate body so that the positions of the multi-layer amorphous alloy sheets 100 are accurately aligned and will not shift. Then, the fasteners 30 are tightened so that the upper plate body abuts against the positioning posts 20. At this time, the stacking height of the multi-layer amorphous alloy sheets 100 reaches the target height. Then, as Figure 9 and Figure 10 shown, the first positioning member 40, the second positioning member 50, and the third positioning member 60 are pulled out, and the stacked and fastened device is placed in an impregnating device for impregnation so that the multi-layer amorphous alloy sheets 100 are uniformly bonded.

[0052] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
