Abstract
Description
Technical Field
[0001] This application relates to the field of metal strip composite technology, and in particular to multilayer metal strip composite devices. Background Technology
[0002] High-silicon steel is a new type of environmentally friendly and energy-saving metallic material. Similar to amorphous materials, it features high magnetic permeability and high resistivity. Products made using high-silicon steel and amorphous materials have higher magnetic permeability and lower losses compared to ordinary silicon steel products. High-silicon steel and amorphous materials are gradually replacing silicon steel sheets in energy-saving applications (such as power distribution transformers and new energy vehicle motors), and their demand in the power industry is also increasing.
[0003] However, both of these materials are generally produced using a rapid cooling method in the industry, resulting in thinner finished products, only 0.02–0.035 mm thick, while ordinary silicon steel sheets are 0.2–0.5 mm thick, a difference of more than 10 times. This significantly increases the stamping and stacking costs of high-silicon steel and amorphous materials, limiting their application and promotion.
[0004] To improve efficiency, the industry currently mainly reduces stamping and lamination costs by laminating multi-layer high-silicon steel and amorphous thin strips. Existing lamination equipment uses a lamination roller to laminate the multi-layer coated thin strips together, and then dries the adhesive in an oven. However, this lamination process has a short lamination time because the lamination roller is in single-line contact. In addition, the lamination process and the adhesive curing process are separated. As a result, the thin strip will partially delaminate after passing through the lamination roller because the adhesive has not yet cured. This will cause wavy skirt defects on the edge of the thin strip, which will seriously affect the stamping yield of the composite thin strip. Moreover, this defect will continue to worsen with the increase of the number of lamination layers. Utility Model Content
[0005] This invention proposes a multilayer metal strip composite device, which aims to at least solve the problem in related technologies where wavy skirt defects are generated at the edge of the strip during the composite preparation process, which affects the stamping yield of the composite strip.

[0009] A coating roller assembly, located downstream of the unwinding roller, is configured to apply adhesive to the surface of a single-layer thin strip.
[0010] An axial flow fan, located downstream of the coating roller, is configured to air dry the coated single-layer strip.
[0011] A composite limiting roller, located downstream of the axial flow fan, is configured to align the stacked single-layer thin strips after multiple layers of air drying.
[0012] A composite pressing assembly is disposed between the composite limiting roller and the winding roller, and is configured to perform flattening and hot pressing composite of the stacked single-layer thin strip.
[0013] The coating roller, the axial flow fan, the composite limiting roller, and the composite pressing assembly are arranged sequentially on the thin strip composite path.
[0014] In some embodiments, the coating roller assembly includes an upper coating roller and a lower coating roller, which are respectively disposed on both sides of the single-layer thin strip and configured to simultaneously coat the upper and lower surfaces of the single-layer thin strip with adhesive.
[0015] In some embodiments, the laminating apparatus further includes coating rollers, at least two of which are disposed on opposite sides of the upper coating roller and configured to press at least a portion of the surface of the single-layer strip against the surface of the upper coating roller.

[0022] Compared with the prior art, the technical solution provided in this application has at least the following beneficial effects or advantages:
[0023] The laminating apparatus in this application includes coating, surface drying, and hot-pressing laminating processes. After coating, the single-layer thin strip enters the surface drying stage, where an axial flow fan dries the coated thin strip. The solvent of the adhesive on the thin strip evaporates during the drying process, leaving only the solute. This prevents the solvent from failing to evaporate in the sealed environment during the laminating stage, improving the laminating effect. After surface drying, the single-layer thin strip enters the laminating stage. Here, the laminating limiting roller first aligns the multiple layers of air-dried single-layer thin strips, and then the laminating pressing assembly performs flat hot-pressing lamination. By setting up the laminating pressing assembly, the traditional single-line pressure of the laminating roller is improved to planar pressure lamination, resulting in a longer laminating time. The laminating plate is designed to be heated, and the adhesive cures under high temperature and high pressure. The laminating process and the adhesive curing process are carried out simultaneously, resulting in a flatter laminating thin strip without wavy skirts, higher interlayer bonding strength, and the ability to laminate a higher number of metal thin strip layers. It is applicable to different types of metal thin strips and different types of adhesives.

Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.
[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0042] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.
[0043] Please see Figures 1 to 3 In the multilayer metal strip lamination process, the single-layer metal strip released by the unwinding roller 10 is coated by the coating roller group 30. The coated multilayer strip is then pulled by the take-up roller 20, passing between the upper composite roller 101 and the lower composite roller 102. The multilayer strip is laminated by the upper and lower rollers of the composite roller. After detaching from the composite roller, the multilayer strip remains laminated due to the adhesive between the strips and the tension of the limiting roller. The laminated multilayer strip enters an oven for drying, where the adhesive between the layers cures at a high temperature of 180°C, completing the lamination process.
[0044] The inventors discovered that directly laminating the coated thin strips resulted in extremely poor lamination of the multilayer gold strips, with severe delamination. Furthermore, upon inspection of the delaminated metal strip surface after lamination, they found that although the adhesive on the metal strip surface had cured, the surface was uneven, caused by the solvent failing to evaporate and forming bubbles.
[0045] Based on the above scheme, combined with Figure 2 The inventors added an axial flow fan 40 before the metal strip lamination process. During the stage between the strip leaving the lamination rollers and the curing of the interlayer adhesive, the multi-layered composite strip inevitably delaminates due to the warping and deformation of the metal strip itself, as the adhesive is not yet cured. The severity of delamination is related to the adhesive's viscosity and the flatness of the metal strip. Furthermore, the lamination rollers operate on a single-line contact basis, resulting in a short lamination time; the lamination process and the adhesive curing process are separate. After the strip passes through the lamination rollers, localized delamination occurs because the adhesive is not yet cured, creating wavy skirt defects at the edges. This severely affects the stamping yield of the composite strip, and these defects worsen with the increase in the number of lamination layers.
[0046] Based on this, in order to improve the technical problem that after the metal strip passes through the composite roller, it will partially delaminate due to the adhesive not being cured, and the strip edge will produce a wavy skirt defect, which affects the stamping yield of the composite strip and this defect will be continuously aggravated with the increase of the number of composite layers, the inventors have proposed the following solution.
[0047] Please see Figure 3 This embodiment provides a multilayer metal strip laminating device. The laminating device includes an unwinding roller 10, a coating roller assembly 30, an axial flow fan 40, a laminating limiting roller 50, and a laminating clamping assembly 60. The unwinding roller 10 is configured to release the single-layer strip to be laminated. Since the laminating process includes at least two types of single-layer strips, the take-up roller 20 is configured to take up the laminated strip. A strip laminating path is defined between the take-up roller 20 and the unwinding roller 10. The coating roller assembly 30 is located downstream of the unwinding roller 10 and is configured to apply adhesive to the surface of the single-layer strip. Adhesive coating; an axial flow fan 40 is positioned downstream of the coating roller 30 and is configured to air-dry the coated single-layer thin strip; a composite limiting roller 50 is positioned downstream of the axial flow fan 40 and is configured to align the multiple layers of air-dried single-layer thin strips; a composite pressing assembly 60 is positioned between the composite limiting roller 50 and the take-up roller 20 and is configured to perform flattening and hot-pressing composite of the stacked single-layer thin strips; wherein, the coating roller 30, the axial flow fan 40, the composite limiting roller 50, and the composite pressing assembly 60 are arranged sequentially on the thin strip composite path.
[0048] Furthermore, the composite device also includes a composite guide roller 70, which is disposed between the composite pressing assembly 60 and the winding roller 20. The top of the composite guide roller 70 is flush with the top of the composite limiting roller 50. The composite limiting roller 50 and the composite guide roller 70 can keep the composite metal strip flat before and after hot pressing, thereby improving the yield of the composite metal strip.
[0049] It should be understood that the unwinding roller 10, coating roller assembly 30, axial flow fan 40, composite limiting roller 50, and composite pressing assembly 60 can be mounted on a frame. This frame can be the base of the multi-layer metal strip composite device, a part of the base, or other supporting structures. For the sake of simplicity, Figure 3 The specific structure of the frame is not shown.
[0050] It should be noted that, for the unwinding roller 10, since the composite device performs hot pressing composite of multiple layers of metal strip, the number of unwinding rollers 10 is at least two, but can also be three, four or five, depending on the number of layers of the composite metal strip. The unwinding roller 10, coating roller group 30, axial flow fan 40 and composite limiting roller 50 are all set in the same direction, and their specific structure and how they operate are directly available from existing technology, so they will not be described in detail here.
[0051] In this embodiment, the laminating device includes coating, surface drying, and hot-pressing laminating processes. After coating, the single-layer thin strip enters the surface drying stage. Here, the axial flow fan 40 dries the coated thin strip, and the solvent of the adhesive on the thin strip evaporates through air drying, leaving only the solute. This prevents the solvent from failing to evaporate in the sealed environment during the laminating stage, thus improving the laminating effect. After surface drying, the single-layer thin strip enters the laminating stage. Here, the laminating limiting roller 50 first aligns the multiple layers of air-dried single-layer thin strips, and then performs flat hot-pressing laminating through the laminating pressing component 60. By setting the laminating pressing component 60, the single-line pressure of the traditional laminating roller is improved to planar pressure laminating, resulting in a longer laminating time. The laminating plate 61 is set to be heatable, and the adhesive is cured under high temperature and high pressure. The laminating process and the adhesive curing process are carried out simultaneously, resulting in a flatter thin strip after laminating, without wavy skirts, higher interlayer bonding strength, and a higher number of metal thin strip layers that can be laminated. It is applicable to different types of metal thin strips and different types of adhesives.
[0052] Please see Figure 4 In some embodiments, the coating roller group 30 includes an upper coating roller 31 and a lower coating roller 32, which are respectively disposed on both sides of the single-layer thin strip and configured to simultaneously coat the upper and lower surfaces of the single-layer thin strip with adhesive. In this embodiment, taking a three-layer composite metal thin strip as an example, the first single-layer thin strip 201, the second single-layer thin strip 202, and the third single-layer thin strip 203 are the upper, middle, and lower layers of the composite metal thin strip, respectively. Since the top surface of the first single-layer thin strip 201 is the upper surface of the composite metal thin strip, it is not necessary to set the upper coating roller 31 on the top surface of the first single-layer thin strip 201 for adhesive coating. Similarly, since the bottom surface of the third single-layer thin strip 203 is the lower surface of the composite metal thin strip, it is not necessary to set the lower coating roller 32 on the bottom surface of the third single-layer thin strip 203 for adhesive coating.
[0053] As for the second single-layer thin strip 202, since the top surface of the second single-layer thin strip 202 needs to be bonded to the bottom surface of the first single-layer thin strip 201, and the bottom surface of the second single-layer thin strip 202 needs to be bonded to the top surface of the third single-layer thin strip 203, an upper coating roller 31 and a lower coating roller 32 are provided on both sides of the upper and lower surfaces of the second single-layer thin strip 202 to coat the adhesive, thereby improving the bonding strength of each single-layer thin strip after hot pressing and bonding.
[0054] It should be noted that the production process of four- or five-layer composite metal strips is similar to that of three-layer composite metal strips. It only requires replicating the multiple rollers and related equipment on the path corresponding to the third single-layer strip 203, i.e., designing the same path.
[0055] Of course, please see Figure 5When the composite metal strip to be laminated consists of two layers, only the lower coating roller 32 is set in the corresponding upper strip process path, and only the upper coating roller 31 is set in the corresponding lower strip process path. Alternatively, it can be understood as removing the process path corresponding to the second single-layer strip 202 in this embodiment.
[0056] It should also be noted that, provided that the upper coating roller 31 and the lower coating roller 32 are designed to be upstream of the axial flow fan 40, their positions can be determined according to actual needs and are not restricted.
[0057] Specifically, the first single-layer thin strip 201 is unwound from the unwinding roller 10 corresponding to the upper thin strip, passes through the limiting roller corresponding to the upper layer, and is coated with the bottom adhesive by the lower coating roller 32 corresponding to the upper thin strip; the second single-layer thin strip 202 is unwound from the unwinding roller 10 corresponding to the middle thin strip, passes through the limiting roller corresponding to the middle thin strip, and is coated with the top adhesive by the upper coating roller 31 corresponding to the middle thin strip. The two coating pressure rollers 311 corresponding to the middle thin strip press the middle thin strip... The second single-layer thin strip 202 is pressed onto the upper coating roller 31 corresponding to the middle layer thin strip, and then passes through the limiting roller corresponding to the middle layer to the lower coating roller 32 corresponding to the middle layer thin strip to coat the bottom surface of the middle layer thin strip with adhesive; the third single-layer thin strip 203 is released from the unwinding roller 10 corresponding to the bottom layer thin strip, passes through the limiting roller corresponding to the bottom layer thin strip to the upper coating roller 31 of the bottom layer thin strip to coat the top surface adhesive, and the coating pressure roller 311 corresponding to the bottom layer thin strip presses the bottom layer thin strip onto the coating roller. The top, middle, and bottom layers of thin strips, each coated with adhesive, enter the drying area. An axial flow fan 40 blows air onto the coated thin strips. The adhesive on the surfaces of the first single-layer thin strip 201, the second single-layer thin strip 202, and the third single-layer thin strip 203 is dried by the axial flow fan 40, and all the solvent evaporates. The thin strips are stacked together by the composite limiting roller 50, and under the traction of the composite thin strip take-up roller 20, the stacked thin strips enter the composite pressing assembly 60 for hot pressing. The thin strips are tightly bonded together under high temperature and high pressure. The bonded thin strips pass through the composite guide roller 70 and are then wound up by the composite thin strip take-up roller 20.
[0058] Please see Figure 6 In some embodiments, the laminating apparatus further includes coating rollers 311, at least two coating rollers 311 being disposed on both sides of the upper coating roller 31, configured to press at least a portion of the surface of the single-layer strip against the surface of the upper coating roller 31. Specifically, the horizontal surface formed by the bottom of the two coating rollers 311 should be lower than the top of the upper coating roller 31 in the vertical direction, so that the surface of the single-layer strip to be coated with adhesive is completely coated.
[0059] Furthermore, continue to combine Figure 6The laminating device also includes a thin strip limiting roller 80, which is located downstream of the unwinding roller 10 and is configured to adjust the laminating path of the single-layer thin strip. The thin strip limiting roller 80 can be located between the unwinding roller 10 and the coating roller 30, or between the coating roller 30 and the laminating limiting roller 50. At the same time, two, three or four rollers can be continuously spaced along the same single-layer thin strip path, depending on the actual needs. The setting of the thin strip limiting roller 80 can be used to limit the laminating path of the single-layer thin strip on the one hand, and to adjust the tension of the single-layer thin strip on the other hand.
[0060] Please see Figure 7 and Figure 8 In some embodiments, the composite pressing assembly 60 includes two opposing composite pressure plates 61, with an adjustable hot-pressing composite zone formed between the two composite pressure plates 61; a thermal resistance wire 611 is provided inside the composite pressure plate 61, and the thermal resistance wire 611 is distributed in a serpentine pattern along the length direction of the composite pressure plate 61; a bending portion 612 is provided at both ends of the composite pressure plate 61 along the length direction, and the bending portion 612 bends in a direction away from the hot-pressing composite zone; a pressure rod 62 is provided on the surface of each composite pressure plate 61 away from the hot-pressing composite zone, and the pressure rod 62 is configured to apply vertical pressure to the composite pressure plate 61 to drive the two composite pressure plates 61 to move in opposite directions.
[0061] Optionally, the composite clamping assembly 60 can also be provided with an open frame 63, with two composite pressure plates 61 disposed opposite each other in the cavity of the frame 63. By setting the pressure rod 62 to be slidably connected to the frame 63, the pressure rod 62 can only move in the vertical direction. At the same time, the power source for the movement of the pressure rod 62 can be a motor or a hydraulic cylinder connected to the outside of the frame 63 to provide a power source for the pressure rod 62 to move up and down. Alternatively, a return spring 621 can be coaxially sleeved around the pressure rod 62. The return spring 621 is used to reset the pressure rod 62. That is, when it is necessary to perform thermal bonding of multi-layer metal strips between the two composite pressure plates 61, the pressure rod 62 is pulled by a structure outside the frame 63 (such as a motor). After the multi-layer metal strip is placed and positioned, the pressure rod 62 is released and pressure is provided by the return spring 621, thereby maintaining a certain pressure during the thermal bonding process of the multi-layer metal strip.
[0062] In this embodiment, the stacked thin strips enter the composite pressing assembly 60. The heating resistance wire 611 on the composite pressing assembly 60 can raise the temperature of the composite pressing plate 61 to 180°C. The adhesive coated on the surface of the thin strips in the composite pressing plate 61 melts and then fuses together when heated. During this process, the composite pressing assembly 60 continuously provides pressure to the thin strips, allowing the multiple layers of thin strips to adhere tightly together during the adhesive melting process. This avoids the problem of thin strip delamination before the adhesive melts and solidifies due to insufficient adhesive strength or thin strip deformation.
[0063] It should be noted that the composite pressure plate 61 can be made of stainless steel, and the contact surface with the thin strip is mirror polished to reduce its surface friction coefficient, ensuring that the thin strip can slide smoothly on the surface of the composite pressure plate 61 while the composite pressing assembly 60 applies pressure to the thin strip; in addition, the composite pressure plate 61 in the composite pressing assembly 60 can also be arc-shaped, so that the composite thin strip also presents an arc shape, which will be more conducive to winding and prevent the cured adhesive from peeling off due to the inconsistency between the inner and outer dimensions of the composite thin strip during winding.
