Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a lamination substrate preparation equipment, a motor core preparation equipment, and a motor manufacturing equipment. Background Technology

[0002] Compared to traditional silicon steel core drive motors, motors with amorphous stators and rotors offer advantages such as higher energy efficiency and the ability to achieve high speeds, power densities, or torque densities by increasing frequency while maintaining high motor efficiency. However, manufacturing amorphous motors requires first continuously stamping individual laminations, which are then axially stacked. Since the thickness of amorphous materials is typically between 20-50 μm, which is unsuitable for stamping processes, it is necessary to first stack the amorphous materials to create a lamination substrate of sufficient stamping thickness.

[0003] In the prior art, after the substrate film is unwound by the main unwinding device, it passes through the corona device and the dust-adhesive device in sequence before entering the coating device for adhesive coating. The substrate film coated with adhesive then enters the heating channel of the baking device, and the substrate film coated with adhesive and the substrate film without adhesive coating are then laminated together to form a composite material.

[0004] In existing technologies, there is a problem of misalignment during pressing, which can lead to wear and tear on the substrate edge, and may even cause some strips to be scrapped, resulting in material loss and increased production costs. Utility Model Content

[0020] In one possible implementation, a winding device is also included. Located between the pressing device and the first drying device along the conveying path of the sheet material, the winding device winds the multilayer sheet substrate into a roll.

[0021] In a second aspect, an apparatus for preparing an electric motor core is provided, including the lamination substrate preparation apparatus provided in any embodiment of the first aspect.

[0022] In one possible implementation, the motor core manufacturing equipment further includes a stamping device and a stacking device.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, when describing pipelines or channels, the terms "connection" and "linking" used in this application have the meaning of conducting electricity. The specific meaning needs to be understood in conjunction with the context.

[0039] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0040] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0041] like Figure 1 As shown, this application provides a lamination substrate preparation equipment 100, a motor core preparation equipment 200, and a motor preparation equipment. In a first aspect, a lamination substrate preparation equipment is provided, which includes a feeding device 1, a pressing device 2, and a correction device 3.

[0042] The feeding device 1 is suitable for providing raw materials for multi-layer stamping.

[0043] The pressing device 2 is suitable for pressing multi-layer sheet raw materials to form sheet substrate. The pressing device 2 applies precise and controllable pressure to the multi-layer sheet raw materials, so that the multi-layer raw materials are tightly bonded under pressure, thereby forming a sheet substrate that meets the requirements.

[0044] When the equipment for preparing stamping substrate is in operation, the feeding device 1 provides multi-layer stamping raw materials, and the pressing device 2 presses the multi-layer stamping raw materials to form stamping substrate.

[0045] The correction device 3 is located between the feeding device and the pressing device 2 along the conveying path of the sheet material. The correction device 3 is used to correct the multi-layer sheet material so that the multi-layer sheet material is aligned in the width direction.

[0046] By using the correction device 3, the multi-layer stamping raw material is corrected before entering the pressing device 2, which effectively reduces the positional deviation of the multi-layer stamping raw material before entering the pressing device 2, so that each layer of raw material is precisely aligned in the width direction, reducing the positional deviation before entering the pressing device 2, and thus reducing the occurrence of misalignment during the pressing process.

[0047] Furthermore, it can keep the raw materials for stamping under uniform stress and reduce the loss of raw materials for stamping.

[0048] For example, the substrate for the lamination can be an iron-based amorphous alloy. Iron-based amorphous alloys have excellent soft magnetic properties: high maximum permeability, low coercivity and very low iron loss, and a strength 3-4 times that of silicon steel.

[0049] The embodiments of this application will be described in detail below with reference to the accompanying drawings, and the application scenarios of the embodiments of this application will be introduced first before the detailed description of the embodiments of this application.

[0050] The equipment for preparing the stamping substrate provided in this application can be applied to the manufacturing of power energy equipment, industrial automation equipment, electronic products, aerospace equipment, etc.

[0051] Specifically, in the manufacturing of power energy equipment, the high-precision stamping substrate produced by the stamping substrate preparation equipment 100 is a key material for manufacturing transformer cores.

[0052] In the manufacturing of industrial automation equipment, various industrial motors are the core power source for industrial automation. For example, the lamination substrate preparation equipment 100 can be used to manufacture drive motors for new energy vehicles. The lamination substrate preparation equipment 100 can also be used to manufacture high-efficiency and energy-saving industrial motors, which are applied in the production processes of industrial equipment such as machine tools, fans, water pumps, and robots, meeting the demand for high-efficiency power in industrial production.

[0053] In the manufacturing of electronic products, such as home appliances, computers, and mobile phones, small motors and transformers are widely used. Equipment for preparing lamination substrates can be applied to these electronic product manufacturing processes.

[0054] The lamination substrate preparation equipment provided in this application can be used in motor core preparation equipment 200 to produce stator cores and rotor cores in motors. When the lamination substrate is an amorphous alloy, motors with amorphous stator and rotor have the advantages of being more energy-efficient and easier to achieve high speed, high power density or high torque density by increasing the frequency while ensuring high motor efficiency.

[0055] In one possible implementation, such as Figure 2As shown, the correction device 3 includes a position detection structure 31 and a position adjustment structure 32. The position detection structure 31 is adapted to detect the deviation angle of the sheet material relative to a preset conveying direction. The position adjustment structure 32 is connected to the position detection structure 31. Based on the deviation angle, the position detection structure 31 adjusts the position of the sheet material in the opposite direction of the deviation direction to align the multi-layer sheet material in the width direction.

[0056] The position detection structure 31 detects the deviation angle of the blanking raw materials, such as blanking blanks, relative to the preset conveying direction in real time. After the position detection structure 31 obtains the deviation angle information, it transmits the deviation angle to the position adjustment structure 32 connected to it.

[0057] The position adjustment structure 32 adjusts the position of the sheet metal raw material by adjusting the rotation speed, angle, or other related actuators of the conveyor rollers based on the received deviation angle, thereby aligning the multi-layer sheet metal raw materials in the width direction. For example, if the raw material is detected to be offset to the right, the position adjustment structure 32 controls the conveyor rollers to make a slight adjustment to the left, so that the raw material returns to the preset conveying path.

[0058] This ensures the forming quality of the stamping substrate, making the layers of the stamping substrate fit tightly and be accurately positioned, meeting the requirements of high-precision production.

[0059] At the same time, it ensures that the raw materials are subjected to uniform stress during the pressing process, effectively reducing the loss of raw materials caused by uneven stress, improving the utilization rate of raw materials, and reducing production costs.

[0060] Furthermore, it reduces production interruptions and defect rates caused by misalignment, and improves the production efficiency and product quality of the entire stamping substrate preparation process.

[0061] For example, the position detection structure 31 includes, but is not limited to, photoelectric sensors and laser sensors.

[0062] It should be noted that the alignment of multi-layer stamping raw materials in the width direction means that one side of the multi-layer stamping raw material is aligned along the width direction, and the other side opposite to one side of the multi-layer stamping raw material is also aligned.

[0063] The alignment of multi-layer sheeting raw materials in the width direction also means that, along the direction perpendicular to the sheeting raw materials, the orthographic projection of one layer of sheeting raw materials is located in the area where another layer of sheeting raw materials is located.

[0064] In one possible implementation, such as Figure 2As shown, the position detection structure 31 includes a signal transmitter 311 and a signal receiver 312 arranged at intervals. A receiving space is provided between the signal transmitter 311 and the signal receiver 312. The blanking raw material passes through the receiving space when it is conveyed between the feeding device 1 and the pressing device 2.

[0065] When the raw material for stamping is conveyed between the feeding device 1 and the pressing device 2 and passes through the receiving space, the signal transmitter 311 continuously emits signals, such as infrared or laser signals. When there is no raw material to obstruct the signal, the signal receiver 312 can fully receive the signals emitted by the signal transmitter 311.

[0066] When the raw material for stamping shifts position, it enters the signal transmission path between the signal transmitter 311 and the signal receiver 312, thus blocking part of the signal. The signal receiver 312 calculates the deviation angle of the raw material relative to the preset conveying direction based on changes in the received signal, such as a decrease in signal strength or the duration of signal interruption, and then transmits this deviation angle information to the position adjustment structure 32.

[0067] Alternatively, when the raw material for stamping is on a preset conveying path, it may partially obstruct the signal. When the raw material deviates from the preset conveying path, the area obstructing the signal may increase or decrease. The portion of the signal obstructed by the raw material can be calculated based on the signal transmission area.

[0068] The positional deviation of the punching material is determined by the signal change between the signal transmitter 311 and the signal receiver 312. This method can accurately capture extremely subtle positional changes of the material, ensuring high detection accuracy and providing a reliable data basis for subsequent precise correction.

[0069] Meanwhile, the detection method using signal transmitter 311 and signal receiver 312 is highly adaptable and stable. Signal transmitter 311 and signal receiver 312 are not easily affected by external environmental factors such as dust or slight vibrations, ensuring stable operation of position detection in complex production environments and continuously providing accurate data for monitoring the conveying status of stamping raw materials.

[0070] In one possible implementation, such as Figure 2 As shown, the position adjustment structure 32 includes a guide roller 321 and a drive member 322. The guide roller 321 is used to guide the blanking material. The drive member 322 is connected to the guide roller 321 and is used to drive the guide roller 321 to swing, so that the guide roller 321 adjusts the position of the blanking material in the opposite direction of the deviation direction.

[0071] The guide roller 321 is used to guide the blanking material. Exemplarily, the blanking material is wound around a portion of the guide roller 321, and the guide roller 321 exerts a force on the blanking material. The guide roller 321 adjusts the position of the blanking material by changing its own posture, its relative positional relationship with the blanking material, and the interaction force between the guide roller 321 and the blanking material.

[0072] Specifically, when the steering roller 321 swings, the tangential direction of the contact point between the surface of the steering roller 321 and the raw material of the stamping changes, thereby changing the direction of the frictional force on the raw material of the stamping.

[0073] Under normal circumstances, the force exerted on the blanking material in the conveying direction is along a preset path. However, after the guide roller 321 swings, the frictional force will decompose into a lateral component. The direction of this lateral component is opposite to the deviation direction of the blanking material, which will push the blanking material to move to the correct position.

[0074] During the oscillation of the guide roller 321 and the application of a lateral force, the position detection structure 31 continuously monitors the position of the sheet material. As the position of the sheet material gradually moves towards the preset direction, the deviation angle gradually decreases. When the position detection structure 31 detects that the sheet material has returned to the preset conveying path, that is, when the multi-layer sheet material is aligned in the width direction, it feeds this information back to the drive unit 322. Based on the feedback information, the drive unit 322 stops driving the guide roller 321 to oscillate, the guide roller 321 returns to its initial state, and the sheet material continues to be conveyed along the correct path.

[0075] It should be noted that the correction device 3 also includes a controller, which is connected to the position detection structure 31. In the above process, the controller performs the functions of transmitting, analyzing, and outputting information.

[0076] For example, the drive unit 322 includes, but is not limited to, power equipment such as motors and cylinders. The drive unit 322 is connected to the steering roller 321 through transmission mechanisms such as gears, racks, lead screws, and chains.

[0077] In one possible implementation, see [link to previous document]. Figure 1 The sheet metal substrate preparation equipment 100 also includes a first coating device 4. The drive unit 322 is along the conveying path of the sheet metal raw material. The first coating device 4 is located between the feeding device 1 and the pressing device 2. The first coating device 4 is adapted to apply adhesive to the sheet metal raw material so that the multilayer sheet metal raw materials are bonded after passing through the pressing device 2.

[0078] The first coating unit 4 is equipped with an adhesive storage container and a conveying device. The adhesive storage container is used to store the adhesive to be coated, and the conveying device transports the adhesive from the storage container to the coating work area. The conveying device can be a pump-type device, and by controlling the flow rate and pressure of the pump, a stable and precise supply of adhesive is ensured.

[0079] For example, the coating method of the first coating device 4 includes, but is not limited to, microgravure coating, doctor blade coating or spray coating.

[0080] For example, adhesives include, but are not limited to, epoxy resins.

[0081] Multi-layered stamping raw materials are bonded together in pressing device 2 after being coated with adhesive to form a single stamping substrate. The adhesive enhances the bonding force between the layers of stamping raw materials, making the stamping substrate less prone to delamination or cracking during subsequent processing and use, thus improving the structural stability and reliability of the stamping substrate.

[0082] The thickness of the adhesive layer coated by the first coating device 4 is less than or equal to 3 μm. At the same time, the thickness of the adhesive layer is made less than or equal to 10% of the thickness of a single layer of lamination raw material, thereby making the lamination factor greater than 90%. The lamination factor refers to the ratio of the volume of the amorphous alloy to the total volume of the stator.

[0083] In one possible implementation, see [link to previous document]. Figure 1 The first coating device coats the same side of the multilayer stamping raw material with adhesive material.

[0084] Coating is applied only to the same side of the multi-layer sheet material, eliminating the need to frequently switch coating positions between different sides of the material. This simplifies the operation of the coating device, reduces operational difficulty and complexity, and improves production efficiency.

[0085] Coating on the same side makes it easier to maintain and stabilize the parameters of the coating equipment, such as coating speed, pressure, and adhesive flow rate. This helps to achieve a more uniform coating effect, reduces coating unevenness caused by improper parameter adjustments, and improves the stability of product quality.

[0086] Coating on the same side makes it easier to control the lamination coefficient of the motor core.

[0087] In one possible implementation, see [link to previous document]. Figure 1 Multiple correction devices 3 are provided.

[0088] Multiple correction devices 3 are provided, and multiple correction devices 3 can form a multi-level correction system to gradually correct the deviation of the material.

[0089] Multiple correction devices 3 provide a certain degree of redundancy. Even if one correction device 3 fails or its performance degrades, the other correction devices 3 can still continue to work, maintaining a certain degree of correction function, ensuring that the production process will not be interrupted due to a problem with a single device, and improving the reliability and stability of the entire system.

[0090] Multiple correction devices 3 work together to perform correction tasks, which can reduce the workload of a single correction device 3.

[0091] In one possible implementation, see [link to previous document]. Figure 1 The web guiding device 3 includes a first web guiding device 33 and a second web guiding device 34. The first web guiding device 33 is located between the first coating device 4 and the pressing device 2 along the conveying path of the sheet metal raw material. The second web guiding device 34 is located between the feeding device 1 and the first coating device 4 along the conveying path of the sheet metal raw material.

[0092] During the conveying of the raw materials for the stamping, the second correction device 34 can perform coarse adjustments to initially correct larger deviations. The first correction device 33 then performs fine adjustments to further reduce deviations and improve the positional accuracy of the material.

[0093] The first correction device 33 can correct the position of the coated sheet material.

[0094] During the coating process, slight positional shifts or tension changes may occur in the material. The first correction device 33 can detect and correct these deviations in a timely manner, ensuring that the blanking raw material enters the pressing device 2 in the accurate position, ensuring that the multilayer material can be accurately aligned during pressing, reducing problems such as misalignment and uneven stacking, thereby improving the quality and consistency of the product.

[0095] The second correction device 34 is located between the feeding device 1 and the first coating device 4, and can correct the deviation of the sheet material before it enters the coating process.

[0096] The second correction device 34 can promptly detect and correct any positional deviations that may occur during the feeding process, such as the raw material running off track during unwinding or shaking during conveying, ensuring that the material entering the first coating device 4 is in the correct position and orientation.

[0097] After being corrected by the second correction device 34, the blanking material can enter the first coating device 4 more accurately, so that the coating device can apply the adhesive to the raw material more evenly and accurately.

[0098] In one possible implementation, see [link to previous document]. Figure 1The sheet-forming substrate preparation equipment 100 also includes a first thickness detection device 5, which is located between the first coating device 4 and the pressing device 2 along the conveying path of the sheet-forming raw material. The first thickness detection device 5 is used to detect the thickness of the sheet-forming raw material with the adhesive layer.

[0099] It should be noted that the first thickness detection device 5 is used to detect the overall thickness of the adhesive layer and the blanking raw material.

[0100] By detecting the thickness of the raw material with the adhesive layer, the thickness of the adhesive layer can be calculated, thus reflecting the coating effect of the first coating device 4. This allows for timely adjustments to the coating device to ensure that the adhesive thickness on each layer of raw material is less than or equal to 3μm, thereby guaranteeing the bonding effect and stacking coefficient after multilayer material lamination, and improving product consistency and stability.

[0101] In one possible implementation, see [link to previous document]. Figure 1 The feeding device 1 includes multiple air shafts 11, which are used to wind the blanking raw material, and the multiple air shafts 11 are arranged along the pressing direction.

[0102] Multiple air shafts 11 arranged along the pressing direction help to precisely control the pressing process. By reasonably adjusting the conveying speed and tension of the raw material on each air shaft 11, the multi-layer stamping raw materials can be better aligned and adhered during pressing, improving the precision and quality of pressing and reducing product defects such as bubbles and wrinkles caused by raw material position deviations or uneven tension.

[0103] Multiple air shafts 11 are arranged along the pressing direction, which ensures that the sheet material maintains uniform tension during unwinding. This reduces problems such as unstable unwinding speed and deviation of the material caused by excessive load on a single air shaft 11 or uneven force.

[0104] Multiple air expansion shafts 11 are arranged along the pressing direction to facilitate parallel feeding, which can simultaneously provide multiple layers of raw materials to the pressing device 2, meet the requirements of the production process, and improve the automation level and production speed of the production.

[0105] When the raw material for the lamination is amorphous ribbon.

[0106] The width of the single-layer amorphous alloy strip can be the national standard width of 142mm, 170mm and 213mm, or other non-standard widths such as 240mm, 280mm and 300mm; the thickness is greater than or equal to 10μm and less than or equal to 50μm.

[0107] In one possible implementation, see [link to previous document]. Figure 1The pressing device 2 includes a first pressing roller 21 and a second pressing roller 22 arranged at intervals. The first pressing roller 21 and the second pressing roller 22 are used to press multilayer stamping raw materials to form stamping substrates.

[0108] The spacing between the two pressing rollers allows for more uniform pressure on the multi-layer stamping raw material during the pressing process. The first pressing roller 21 and the second pressing roller 22 work together, and by adjusting parameters such as their spacing and pressure, the pressing force on the multi-layer stamping raw material can be controlled to varying degrees.

[0109] The two spaced-apart pressing rollers provide excellent conveying and guiding for multi-layer stamping raw materials. During the pressing process, the raw material is sandwiched between the two pressing rollers and conveyed smoothly along the rotation direction of the pressing rollers, which helps maintain the conveying direction and positional accuracy of the raw material and reduces the occurrence of deviation or displacement of the raw material during the pressing process.

[0110] In one possible implementation, see [link to previous document]. Figure 1 The sheet-forming substrate preparation equipment 100 also includes a first drying device 6. Along the conveying path of the sheet-forming raw materials, the first drying device 6 is located on the side of the pressing device 2 away from the feeding device 1.

[0111] The multilayer stamped substrate is coated with adhesive material. The drying environment provided by the first drying device 6 helps to accelerate the curing process of the adhesive, making the bond between the layers of material stronger.

[0112] The first drying device 6 can evenly distribute heat on the stamping substrate, ensuring that the adhesive is fully cured on the entire surface and in the thickness direction of the substrate.

[0113] The curing temperature and time can be selected according to the properties of the adhesive used.

[0114] When the adhesive material is epoxy resin, the drying temperature of the first drying device 6 is greater than or equal to 120°C and less than or equal to 180°C, and the drying time of the first drying device 6 is greater than or equal to 3 hours and less than or equal to 8 hours.

[0115] In one possible implementation, a winding device is also included. Along the conveying path of the sheet material, the winding device is located between the pressing device 2 and the first drying device 6, and the winding device winds the multilayer sheet substrate into a roll.

[0116] The winding device winds the multi-layer stamped substrate into a roll, giving the substrate a regular and uniform shape, which facilitates subsequent processing, transportation and storage.

[0117] When the rolled-up sheet material enters the first drying device 6, its rolled shape facilitates the operation of the drying equipment and reduces the space occupied within the first drying device 6.

[0118] The winding device winds up the multi-layer stamped substrate in an orderly manner, which protects the edges and surface of the substrate to a certain extent and reduces the possibility of scratches, wear, oxidation and other damage caused by contact with other equipment or the external environment during the conveying process from the pressing device 2 to the drying device, thereby ensuring the quality and performance of the stamped substrate.

[0119] The diameter of the winding device can be any one of 200mm, 400mm, 600mm, 800mm, 1000mm or greater than 1000mm, which can be selected according to the type of stamping raw material so that the rolled stamping substrate has a small curvature.

[0120] This application also provides an electric motor core preparation apparatus 200, which includes the lamination substrate preparation apparatus 100 provided in any of the above embodiments.

[0121] In one possible implementation, see [link to previous document]. Figure 1 The motor core manufacturing equipment 200 also includes a stamping device 01 and a stacking device 02. The stamping device 01 is adapted to stamp the lamination substrate into laminations. Along the conveying path of the lamination substrate, the stacking device 02 is located on the side of the stamping device 01 away from the lamination substrate manufacturing equipment 100, and the stacking device 02 is adapted to stack the laminations into a motor core.

[0122] The stamping device 01 utilizes the powerful pressure generated by equipment such as a punch press to stamp the sheet substrate into a sheet with a specific shape and size through a specific die. The design of the die is determined according to the specific requirements of the motor core. During the stamping process, the sheet substrate undergoes plastic deformation under the action of the die, thereby obtaining the required sheet shape.

[0123] The stacking device 02 stacks the stamped laminations in a certain order and manner, and then applies pressure to make the laminations tightly bonded together to form the motor core.

[0124] In one possible implementation, see [link to previous document]. Figure 1 The motor core preparation equipment 200 includes a second coating device 03. Along the conveying path of the lamination substrate, the second coating device 03 is located between the lamination substrate preparation equipment 100 and the stamping device 01. The second coating device 03 is adapted to apply an adhesive to the lamination substrate so that the lamination substrate is bonded after passing through the stacking device 02.

[0125] The second coating unit 03 is equipped with an adhesive storage container and a conveying device. The adhesive storage container is used to store the adhesive to be coated, and the conveying device transports the adhesive from the storage container to the coating work area. The conveying device can be a pump-type device, and by controlling the flow rate and pressure of the pump, a stable and precise supply of adhesive is ensured.

[0126] For example, the coating method of the second coating apparatus 03 includes, but is not limited to, gravure coating, blade coating or spray coating.

[0127] For example, adhesives include, but are not limited to, self-adhesive coatings.

[0128] The second coating device 03 applies adhesive to the lamination substrate, forming a uniform adhesive layer on the lamination surface. When the laminations are stacked and pressed by the stacking device 02, this adhesive can achieve a stronger bond between the laminations, ensuring that the laminations will not undergo relative displacement due to vibration, electromagnetic force, or other factors during long-term use of the motor core, thereby guaranteeing the structural stability of the motor core.

[0129] Even with precise machining and positioning, tiny gaps may still exist during the lamination process. The adhesive applied by the second coating device 03 can fill these gaps, making the structure of the motor core more compact, reducing magnetic resistance, optimizing the magnetic circuit distribution of the motor, and improving the electromagnetic performance of the motor.

[0130] The thickness of the adhesive layer coated by the second coating device 03 is less than or equal to 3 μm. At the same time, the thickness of the adhesive layer is made less than or equal to 10% of the thickness of a single layer of lamination raw material, thereby making the lamination factor greater than 90%. The lamination factor refers to the ratio of the volume of the amorphous alloy to the total volume of the stator.

[0131] In one possible implementation, see [link to previous document]. Figure 1 The motor core preparation equipment 200 includes a second drying device 04, which is located between the second coating device 03 and the stamping device 01 along the conveying path of the stamping substrate.

[0132] The multi-layered laminations are coated with adhesive material, and the drying environment provided by the second drying device 04 helps to accelerate the curing process of the adhesive, making the bonding between the laminations more secure.

[0133] The second drying device 04 can evenly distribute heat on the multilayer stamping, ensuring that the adhesive is fully cured on the entire substrate surface and in the thickness direction.

[0134] The curing temperature and time can be selected according to the properties of the adhesive used.

[0135] In one possible implementation, the drying temperature of the second drying device 04 is greater than or equal to 130°C and less than or equal to 210°C, and the drying time of the second drying device 04 is greater than or equal to 30 seconds and less than or equal to 50 seconds. After the above-mentioned short-term baking, the adhesive layer on the die enters an activated state, that is, the adhesive layer is not sticky at room temperature.

[0136] This reduces the likelihood of the stamped sheets sticking together due to the adhesive properties during subsequent transportation, storage, or waiting for stacking, ensuring the integrity and independence of the stamped sheets, facilitating operation and processing, and reducing the scrap rate caused by adhesion.

[0137] When laminations are stacked and pressed into a motor core at the lamination device, the adhesive layer regains its adhesiveness when the laminations are pressed and cured at a pressure of 1-3MPa and a temperature of 130-210℃, thus bonding the laminations together to form a tight and stable motor core structure. This ensures that the motor core can withstand various forces during operation, preventing the laminations from loosening or falling off, and extending the service life of the motor.

[0138] In one possible implementation, see [link to previous document]. Figure 1 The motor core manufacturing equipment 200 includes a second thickness detection device 05. Along the conveying path of the stamping substrate, the second thickness detection device 05 is located between the second drying device 04 and the stamping device 01. The second thickness detection device 05 is used to detect the thickness of the stamping substrate with the adhesive layer.

[0139] By detecting the thickness of the stamped substrate with the adhesive layer, it is possible to promptly determine whether the adhesive coating is uniform. The detection device can provide timely feedback to adjust the parameters of the second coating device 03, ensuring uniform adhesive coating.

[0140] By detecting the thickness of the stamping substrate with the adhesive layer, the adhesive layer thickness can be calculated, thus reflecting the coating effect of the second coating device 03. This allows for timely adjustments to the coating device to ensure that the adhesive thickness on each layer of stamping raw material is less than or equal to 3μm, thereby guaranteeing the bonding effect and stacking coefficient after multilayer material lamination, and improving product consistency and stability.

[0141] In one possible implementation, see [link to previous document]. Figure 1 The motor core manufacturing equipment 200 includes a third thickness detection device 06. Located before the second coating device 03 along the conveying path of the lamination substrate, the third thickness detection device 06 is used to detect the thickness of the lamination substrate.

[0142] Before the stamping substrate enters the coating process, the third thickness detection device 06 can detect its thickness to ensure that the thickness of the stamping substrate put into production meets the initial design requirements.

[0143] By detecting the thickness of the stamping substrate, a reference can be provided for the second coating device 03 to determine the appropriate amount of adhesive coating. If the substrate thickness is thin, it may be necessary to appropriately reduce the amount of adhesive coating to avoid excessive adhesive affecting subsequent processing and product performance; conversely, if the substrate thickness is thick, it may be necessary to increase the amount of adhesive coating to ensure the bonding effect between the stampings.

[0144] The thickness of the adhesive layer can be calculated by the difference between the values ​​detected by the third thickness detection device 06 and the second thickness detection device 05, which makes it easier to control the thickness of the adhesive layer and the stacking factor.
