Description

Technical Field

[0001] This utility model relates to the field of strip technology, and in particular to an amorphous composite strip and its preparation system. Background Technology

[0002] With the development of electric vehicles, higher demands are being placed on motor performance, making high efficiency and high functional density increasingly important. One crucial influencing factor is the design of the motor core, which contains hysteresis and eddy current losses, both of which increase with motor frequency. Currently, soft magnetic materials are commonly used for motor cores, with electrical steel and amorphous alloys being the most common. Other amorphous materials exist, such as iron-cobalt alloys and iron-nickel alloys, but electrical steel strip and amorphous strip are the most frequently used raw materials for motor cores. Currently, amorphous strip widths are constant, primarily in three specifications: 142mm, 170mm, and 213mm. During the manufacture of standard-sized motor cores, a large amount of amorphous strip is cut off and unusable, resulting in significant waste. Furthermore, it is difficult to manufacture non-standard large-size motor cores with a diameter of 280mm using amorphous strip of constant width. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model proposes an amorphous composite strip that makes full use of the amorphous strip left over from cutting and can be used to prepare non-standard motor cores.

[0004] This utility model is achieved through the following technical solution: an amorphous composite ribbon, comprising multiple stacked amorphous ribbon layers, each amorphous ribbon layer comprising multiple parallel amorphous ribbons, adjacent amorphous ribbons in each amorphous ribbon layer contacting each other and forming a seam, and the seams between adjacent amorphous ribbon layers being staggered.

[0005] Furthermore, the widths of the amorphous ribbon layers are equal.

[0006] Furthermore, the thickness of the amorphous ribbon layers is equal.

[0007] This utility model is also achieved through the following technical solution: a preparation system for the above-mentioned amorphous composite ribbon, comprising a conveying device, a composite device, and a drying device arranged sequentially. The conveying device includes a plurality of vertically arranged conveying components, which are used to convey amorphous ribbons of the same amorphous ribbon layer and to bring adjacent amorphous ribbons into contact. The composite device includes at least a pair of composite rollers, and a composite channel is formed between the pair of composite rollers. The composite channel allows multiple amorphous ribbon layers to pass through and be composited. The drying device includes an oven, which is used to dry and cure the composited multiple amorphous ribbon layers to obtain the amorphous composite ribbon.

[0008] Furthermore, the pair of composite rollers includes a fixed roller and a pressure roller that are rotatably arranged, and the composite channel is formed between the fixed roller and the pressure roller. The pressure roller can move closer to or further away from the fixed roller to adjust the size of the composite channel.

[0009] Furthermore, an extrusion device is provided between the composite device and the drying device, and the extrusion device further extrudes the composite multiple amorphous ribbon layers.

[0010] Furthermore, the extrusion device includes several second conveyor rollers arranged in parallel, each second conveyor roller having an extrusion roller. The extrusion roller can approach or move away from the second conveyor roller, and approaches the second conveyor roller from above to extrude the multiple composite amorphous ribbon layers located on the conveyor roller.

[0011] Furthermore, a shearing device is provided behind the drying device. The shearing device cuts the multiple amorphous ribbon layers after drying and curing to form the amorphous composite ribbon with a consistent width.

[0012] Furthermore, the conveying assembly includes a plurality of first conveying rollers arranged sequentially along its conveying direction. Each first conveying roller is provided with at least a pair of limiting blocks that can move closer to or further away from each other. The movement trajectory of the pair of limiting blocks is perpendicular to the conveying direction of the conveying assembly. A conveying channel for limiting the conveying of the amorphous ribbon layer is formed between the opposing limiting blocks. The conveying channel allows the amorphous ribbons within the amorphous ribbon layer to contact each other. The extending direction of the conveying channel is the same as the conveying direction of the conveying assembly.

[0013] Furthermore, the conveying device also includes an unwinding machine and a winding machine. The unwinding machine is located in front of the conveying device and is used to wind up the amorphous strip, while the winding machine is located behind the drying device and is used to wind up the amorphous composite strip.

[0014] Compared with the prior art, the amorphous composite strip provided by this utility model can be composited using the amorphous strip left over from cutting, which greatly reduces the waste of resources. Furthermore, it can be composited with amorphous composite strips of non-standard width to prepare motor cores of non-standard size, thus having wider applicability. Attached Figure Description

Detailed Implementation

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1 to 4 As shown, an amorphous composite strip includes multiple stacked amorphous strip layers 10. Each amorphous strip layer 10 includes multiple amorphous strips 11 arranged in parallel. Adjacent amorphous strips 11 in each amorphous strip layer 10 are in contact and form a seam 12. The seams 12 between adjacent amorphous strip layers 10 are staggered to ensure that the strength of the amorphous composite strip is sufficient to meet the strength standards of amorphous motor cores.

[0029] In this process, the amorphous ribbon 11 in each amorphous ribbon layer 10 can be selected from standard-specification amorphous ribbons or from amorphous ribbons cut from the preparation of standard motor cores. This allows for the preparation of amorphous composite ribbons with non-standard widths, which in turn allows for the preparation of non-standard motor cores. Furthermore, it makes full use of the amorphous ribbons remaining after the preparation of standard motor cores, thus avoiding waste of resources.

[0030] The amorphous ribbon layer 10 can be multi-layered. For example, an amorphous composite ribbon includes two stacked amorphous ribbon layers 10. The upper amorphous ribbon layer 10 includes a pair of parallel amorphous ribbons 11. In this case, a standard-sized amorphous ribbon 11 and a cut-off amorphous ribbon 11 can be combined. Please refer to [reference needed]. Figure 2 , 3 As shown, the lower amorphous ribbon layer 10 includes three amorphous ribbons 11 arranged side by side. In this case, a standard-sized amorphous ribbon 11 can be combined with a pair of cut amorphous ribbons 11. Please refer to... Figure 2 , 4 As shown, the seam 12 on the upper amorphous ribbon layer 10 is staggered from the seam 12 on the lower amorphous ribbon layer 10. Please refer to... Figure 2 As shown.

[0031] To facilitate subsequent processing into motor cores, each amorphous ribbon layer 10 of the amorphous composite ribbon has the same width and length. Of course, the thickness of each amorphous ribbon layer 10 can be equal or unequal, but the thickness of the same amorphous ribbon layer 10 is equal.

[0032] Please refer to Figures 5-10As shown, this embodiment also provides a preparation system for preparing the above-mentioned amorphous composite strip, including an unwinding machine 20, a conveying device, a composite device 40, a drying device, and a winding machine 60 arranged sequentially. The unwinding machine 20 is used to wind up standard amorphous strip 11 and / or amorphous strip 11 cut from a standard motor core. Amorphous strip 11 of the same amorphous strip layer 10 are wound on the same unwinding machine 20. The conveying device includes multiple vertically arranged conveying components 30, which are used to convey amorphous strips of the same amorphous strip layer 10. The amorphous ribbon 11 is brought into contact with adjacent amorphous ribbons. The composite device 40 includes at least one pair of composite rollers, and a composite channel 43 is formed between the pair of composite rollers. The composite channel 43 allows multiple amorphous ribbon layers 10 to pass through and be composited to ensure the composite strength of the amorphous composite ribbon. The drying device includes an oven 50, which is used to dry and cure the composite multiple amorphous ribbon layers 10 to obtain an amorphous composite ribbon. The winding machine 60 is used to wind the dried and cured amorphous composite ribbon for use in the preparation of motor cores.

[0033] Among them, there is one winding machine 60, one laminating device 40 and one drying oven 50, and multiple unwinding machines 20, and the conveying components 30 are set up one-to-one with the unwinding machines 20.

[0034] Please refer to Figure 8 As shown, the conveying assembly 30 includes a plurality of first conveying rollers 31 arranged sequentially along its conveying direction. At least one pair of limiting blocks 32 that can move closer to or further away from each other are provided between the first conveying rollers 31. In this embodiment, there are multiple pairs of limiting blocks 32, and the movement trajectory of each pair of limiting blocks 32 is perpendicular to the conveying direction of the amorphous ribbon 11. A conveying channel 33 is formed between the multiple pairs of limiting blocks 32 to limit the conveying of the amorphous ribbon layer 10 and to make adjacent amorphous ribbons 11 in the amorphous ribbon layer 10 contact each other. The extending direction of the conveying channel 33 is the same as the conveying direction of the amorphous ribbon 11.

[0035] Each pair of limiting blocks 32 can have one fixed and the other movable, or both of the limiting blocks 32 can be movable. The limiting blocks 32 can be driven by a stepper motor, cylinder, or hydraulic cylinder, etc. The driving method of the limiting blocks 32 will not be described in detail here, as it is the same as in the prior art. Since one or both of the limiting blocks 32 in each pair can be movable, the width of the conveying channel 33 is variable, making the conveying channel 33 a variable conveying channel, which can adapt to the conveying of amorphous ribbon layers 10 of different widths. Furthermore, by moving the limiting blocks 32, the amorphous ribbons 11 on the same amorphous ribbon layer 10 are laterally limited, so that adjacent amorphous ribbons 11 on the same conveying component 30 can contact each other.

[0036] The limit block 32 is electrically connected to the control center. It inputs the width data of the amorphous ribbon layer 10 and the width data of each amorphous ribbon 11 on the amorphous ribbon layer 10 into the control center. The control center controls the displacement data of the limit block 32 to adjust the width of the transmission channel 33, enabling adjacent amorphous ribbons 11 on the same amorphous ribbon layer 10 to contact each other. The control center's drive control of the limit block 32 is the same as in existing technology and will not be described further here.

[0037] Please refer to Figure 9 As shown, the composite roller includes a fixed roller 41 and a pressure roller 42 that are rotatably disposed. The fixed roller 41 is stationary, and a composite channel 43 is formed between the fixed roller 41 and the pressure roller 42. The pressure roller 42 can move closer to or further away from the fixed roller 41 to adjust the size of the composite channel 43. The composite roller can be a pair or multiple pairs; in this embodiment, a pair of composite rollers is used as an example. The pressure roller 42 is rotatably disposed on a fixed base, which is connected to a drive mechanism. The drive mechanism drives the fixed base to move so that the pressure roller moves closer to or further away from the fixed roller. This drive mechanism can be a cylinder or other mechanisms, which will not be described in detail here, as is the same as in the prior art.

[0038] In another embodiment, an extrusion device 70 is provided between the composite device 40 and the drying device, and the extrusion device 70 further extrudes the composite multiple amorphous ribbon layers 10.

[0039] For details, please refer to Figure 10 As shown, the extrusion device 70 includes several second conveyor rollers 71 arranged in parallel along the transmission direction. The second conveyor rollers 71 are provided with extrusion rollers 72. The extrusion rollers 72 can approach or move away from the second conveyor rollers 71. The extrusion rollers 72 approach the second conveyor rollers 71 from top to bottom to extrude the multiple composite amorphous ribbon layers 10 located on the second conveyor rollers 71. The second conveyor rollers 71 play a supporting and conveying role for the multiple composite amorphous ribbon layers 10. Both the extrusion roller 72 and the second conveyor roller 71 are rotatably mounted on a fixed frame 74. Driving components are provided on both opposite outer sides of the fixed frame 74. These driving components can be a drive motor, a drive cylinder 75, or even other types of driving components. In this embodiment, the drive cylinder 75 is fixedly connected to the support base 76. The two ends of the extrusion roller 72 are rotatably mounted on the support base 76. The fixed frame 74 is also provided with a vertically arranged guide groove 73. The support base 76 slides vertically within the guide groove 73. The drive cylinder 75 drives the support base 76 to move up and down along the guide groove 73, thereby driving the extrusion roller 72 to move up and down along the guide groove 73 to approach or move away from the second conveyor roller 71. This can further improve the composite strength between the multiple amorphous ribbon layers 10.

[0040] In another embodiment, a shearing device 80 is provided between the drying device and the winding machine 60. The shearing device 80 shears the multiple amorphous ribbon layers 10 after drying and curing to form an amorphous composite ribbon with a uniform width. That is, before the shearing device 80, the widths of the multiple amorphous ribbon layers 10 before and after composite may be inconsistent. Only after the shearing action of the shearing device 80 is an amorphous composite ribbon with a uniform width formed.

[0041] The unwinding machine 20, the winding machine 60, the laminating device 40, the drying oven 50, the shearing device 80, and the conveying assembly 30 are all electrically connected to the control center, which controls the operation of the extrusion roller 72, the pressure roller 42, etc.

[0042] Multiple amorphous ribbons 11 wound on the unwinder 20 are conveyed through the conveying channel 33. Under the action of the limiting block 32, the amorphous ribbons 11 of the same amorphous ribbon layer 10 are arranged so that adjacent amorphous ribbons 11 come into contact. After being successively compressed by the composite channel 43 and the extrusion device 70, they enter the oven 50 for heating and curing. The self-adhesive coating on the amorphous ribbons 11 melts and fuses the adjacent amorphous ribbon layers 10 together. Then, they are sheared by the shearing device 80 to form amorphous composite ribbons with the same width. Finally, the amorphous composite ribbons are wound on the winding machine 60 for use in manufacturing motor cores.

[0043] The unwinding machine 20, unwinding machine 60, shearing device 80, drying oven 50 and other devices are all the same as existing technology, and will not be described in detail here.

Those skilled in the art should understand that various modifications and equivalent substitutions can be made to this utility model without departing from its scope. Furthermore, various modifications can be made to this utility model for specific situations or circumstances without departing from its scope. Therefore, this utility model is not limited to the specific embodiments disclosed, but should include all embodiments falling within the scope of the claims of this utility model.
