DETAILED DESCRIPTION
[0032] In order to make the purposes, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.
[0033] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application.

[0034] It should be understood that the "one embodiment" or "an embodiment" mentioned throughout the specification means that the specific features, structures or characteristics related to the embodiment are included in at least one embodiment of the present application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily mean the same embodiment. In addition, these specific features, structures or characteristics can be combined in one or more embodiments in any suitable manner.
[0035] The embodiment of the present application provides a flat wire motor stator coating device. The flat wire motor stator coating device fixes the laminated microporous plate 300 and the annular spoiler 400 at the lower port a2 of the powder storage box 100, and the annular spoiler 400 can cover the edge part of the microporous plate 300. The orthographic projection of the annular spoiler 400 on the plane where the lower port a2 of the powder storage box 100 is located can cover the area where the annular first opening area a21 in the lower port a2 is located. In this way, the annular spoiler 400 reduces the gas inlet area from the microporous plate 300 to the lower port a2 of the powder storage box 100, improves the utilization rate of compressed gas, and changes the original flow path when the compressed gas flow passes through the annular spoiler 400, thereby avoiding the occurrence of the Coanda effect, i.e. reducing the flow of compressed gas along the inner wall of the powder storage box 100, weakening the gas flow around the powder storage box 100, reducing the gas bubbles generated by the fluidization around the powder storage box 100, and making the overall fluidization of the powder storage box 100 more uniform, the powder fluidization effect is better, and the coating thickness of the flat wire motor stator copper wire is uniform.
[0036] The following embodiments illustrate the specific implementation of the flat wire motor stator coating device:
[0037] Please refer to Figure 1 ,Figure 1 is a sectional view of a flat wire motor stator coating device provided by an embodiment of the present application. The flat wire motor stator coating device can include a powder storage box 100, a static pressure chamber 200, at least one microporous plate 300, an annular spoiler 400 and a jet assembly 500, a pressure sensor 1100 and a vibrator 1200.
[0038] The powder storage box 100 in the flat wire motor stator coating device can have oppositely arranged upper and lower ports a1 and a2. The upper port a1 of the powder storage box 100 can be used for the flat wire motor stator A to extend into. The lower port a2 of the powder storage box 100 can include an annular first opening area a21 and a second opening area a22 located in the area surrounded by the annular first opening area a21. The powder storage box 100 can be used to place the coating powder B. Here, the annular first opening area a21 in the lower port a2 of the powder storage box 100 is an opening area connected with the inner side wall of the powder storage box 100. For example, the inner side wall of the powder storage box 100 can be an annular arc-shaped side wall (for example, the powder storage box can be cylindrical), facilitating the flow of the coating powder B in the powder storage box 100.
[0039] The static pressure chamber 200 in the flat wire motor stator coating device can be arranged opposite to the powder storage box 100. The static pressure chamber 200 can have an air outlet port b1.
[0040] The at least one microporous plate 300 and the annular spoiler 400 in the flat wire motor stator coating device are arranged in layers and are fixed between the lower port a2 of the powder storage box 100 and the air outlet port b1 of the static pressure chamber 200. The annular spoiler 400 can cover the edge portion of the microporous plate 300, and the orthographic projection of the annular spoiler 400 on the plane where the lower port a2 of the powder storage box 100 is located can cover the area where the first opening area a21 in the lower port a2 of the powder storage box 100 is located. The annular spoiler 400 can have a ventilation opening b2 in communication with the air outlet port b1 of the static pressure chamber 200, and part of the microporous plate 300 can be exposed from the ventilation opening b2 of the annular spoiler 400. The jet assembly 500 in the flat wire motor stator coating device can be connected with the static pressure chamber 200, and the jet assembly 500 can be used to introduce gas with a preset pressure into the static pressure chamber 200.
[0041] The vibrator 1200 in the flat wire motor stator coating device is fixedly connected with the powder storage box 100. The vibrator 1200 can drive the powder storage box 100 to vibrate, facilitating the fluidization effect of the coating powder B in the powder storage box 100. For example, the vibrator 1200 can be distributed on the side of the static pressure chamber 200 away from the powder storage box 100.
[0042] For example, the operation of the stator coating device for flat wire motor is schematically described as follows: when the stator copper wire of the flat wire motor is coated with powder by using the stator coating device for flat wire motor, the gas jet assembly 500 guides the gas with a preset pressure into the static pressure chamber 200, and the pressure sensor 1100 arranged in the static pressure chamber 200 can be used to detect whether the pressure of the gas in the static pressure chamber 200 reaches the preset pressure (for example, if the pressure of the gas in the static pressure chamber 200 detected by the pressure sensor 1100 does not reach the preset pressure, the gas jet assembly 500 can be adjusted to guide the compressed gas into the static pressure chamber 200); the compressed gas flow passes through the air vents b2 of the annular spoiler 400 and the plurality of micropores in the microporous plate 300, and blows the coating powder B in the powder storage box 100; at this time, the static coating powder B forms a mixed fluidized state with the gas under the action of the gas flow, and the vibrator 1200 drives the powder storage box 100 to vibrate; the preheated stator of the flat wire motor is quickly lowered from the upper port a1 of the powder storage box 100 into the fluidized coating powder B, rotated clockwise by 45°, rotated counterclockwise by 45° to return to the original position, and then quickly lifted up, thereby completing the coating of the stator copper wire of the flat wire motor.
[0043] For the arrangement of the microporous plate and the spoiler, the embodiments of the present application are schematically described in the following three optional implementation manners:
[0044] The first optional implementation manner is described with reference to Figure 2 , Figure 2 is a partial structure schematic diagram of a stator coating device for flat wire motor provided by an embodiment of the present application. The microporous plate 300 can be located between the lower port a2 of the powder storage box 100 and the annular spoiler 400, and the annular spoiler 400 can be fixedly connected to the edge portion of the side of the microporous plate 300 away from the lower port a2 of the powder storage box 100. For example, the microporous plate 300 can be fixedly connected to the edge portion of the lower port a2 of the powder storage box 100 by screwing or clamping, and the connection between the microporous plate 300 and the lower port a2 of the powder storage box 100 needs to be sealed. The edge portion of the side of the annular spoiler 400 away from the lower port a2 of the powder storage box 100 can also be fixedly connected to the microporous plate 300 by screwing or clamping, and the connection between the microporous plate 300 and the annular spoiler 400 needs to be sealed. For example, the number of microporous plates 300 can be one or more, Figure 2 is schematically described by taking one microporous plate 300 as an example.
[0045] The second optional implementation manner is described with reference to Figure 3 , Figure 3Figure 8 is a partial structural schematic diagram of another stator coating device for a flat wire motor provided in an embodiment of the present application. The number of microporous plates 300 is at least two, and the annular spoiler 400 can be fixed between adjacent two of the microporous plates 300. For example, the number of microporous plates 300 can be two or more. Figure 3 The two microporous plates 300 are taken as an example for illustrative description, and the annular spoiler 400 can be fixed between the two microporous plates 300. It should be noted that the connection mode of the microporous plates 300 at the lower port a2 of the powder storage box 100 and the connection mode of the microporous plates 300 and the annular spoiler 400 can refer to the above implementation modes, and will not be described herein again.
[0046] In a third alternative implementation mode, the annular spoiler 400 can be located between the lower port a2 of the powder storage box 100 and the microporous plate 300, and the microporous plate 300 can be fixedly connected with the edge portion of the side of the annular spoiler 400 away from the lower port a2 of the powder storage box 100. For example, the annular spoiler 400 can be fixedly connected with the edge portion of the side of the annular spoiler 400 away from the lower port a2 of the powder storage box 100 by screws or clamps, and the connection between the annular spoiler 400 and the lower port a2 of the powder storage box 100 needs to be sealed. The microporous plate 300 can also be fixedly connected with the edge portion of the side of the annular spoiler 400 away from the lower port a2 of the powder storage box 100 by screws or clamps, and the connection between the microporous plate 300 and the annular spoiler 400 needs to be sealed. For example, the number of microporous plates 300 can be one or more, and one microporous plate 300 is taken as an example for illustrative description in the figure.
[0047] In the embodiments of the present application, please refer to Figure 4 , Figure 4 Figure 9 is a structural schematic diagram of another stator coating device for a flat wire motor provided in an embodiment of the present application. The gas injection assembly 500 in the stator coating device for a flat wire motor can include a multi-stage pressure regulating component 501 and a flow restrictor 502, and the flow restrictor 502 can be located between the multi-stage pressure regulating component 501 and the static pressure chamber 200 and respectively communicate with the multi-stage pressure regulating component 501 and the static pressure chamber 200. The multi-stage pressure regulating component 501 can be used to adjust the pressure of the input compressed gas, and the flow restrictor 502 can be used to adjust the flow of the gas introduced into the static pressure chamber 200.
[0048] For example, when the flat wire motor stator coating device is in a normal working state, first, dry compressed gas in a first pressure threshold range is input to the multi-stage pressure regulating component 501 (for example, a multi-stage pressure regulating valve), and the pressure of the gas is adjusted to a second pressure threshold range through a first pressure regulating area of the multi-stage pressure regulating component 501, and the value of the second pressure is less than the value of the first pressure; then, the pressure of the gas is adjusted to a third pressure threshold range through a second pressure regulating area of the multi-stage pressure regulating component 501, and the value of the third pressure is less than the value of the second pressure; and then, the pressure of the gas is adjusted to a preset pressure through a third pressure regulating area of the multi-stage pressure regulating component 501, and the value of the preset pressure is less than the value of the third pressure. For example, the first pressure threshold range can be 0.6 MPa to 0.8 MPa, the second pressure threshold range can be 0.3 MPa to 0.6 MPa, the third pressure threshold range can be 0.1 MPa to 0.3 MPa, and the preset pressure range can be greater than 0 MPa and less than or equal to 0.1 MPa. It should be noted that please refer to Figure 5 , Figure 5 is a cross-sectional view of a flat wire motor stator after coating powder provided by an embodiment of the present application. Through the above-mentioned multiple adjustments, the gas reaches a preset pressure, and the gas at the preset pressure is mixed with the coating powder to be fluidized, so that the difference between the thickness of the powder coating layer at the round corner of the flat wire stator copper wire and the thickness of the powder coating layer on the copper wire plane is smaller.
[0049] Optionally, as shown in Figure 4 , in a case where the flat wire motor stator coating device includes a pressure sensor 1100, the pressure sensor 1100 can be electrically connected with the multi-stage pressure regulating component 501, the pressure sensor 501 can be used to detect the pressure of the gas in the static pressure chamber 200 and feed back the detected pressure signal to the multi-stage pressure regulating component 501, and the multi-stage pressure regulating component 501 can adjust the pressure of the gas according to the pressure of the gas in the static pressure chamber 200 detected by the pressure sensor 1100 until the pressure of the gas reaches the preset pressure, and finally the stable low-pressure and high-flow gas is transmitted to the coating powder B in the powder storage box 100 through the microporous plate 300 and blows up the coating powder B to form a fluidized state, so as to meet the coating requirements of the flat wire motor stator.
[0050] In the present application, a flat wire motor stator coating system is also provided, please refer to Figure 6 , Figure 6 is a structural schematic view of a flat wire motor stator coating system provided by an embodiment of the present application. The flat wire motor stator coating system can include a dust collection device X and a flat wire motor stator coating device, and the dust collection device X can be in communication with the powder storage box 100 in the flat wire motor stator coating device. In this way, the excess coating powder in the powder storage box 100 can be collected through the dust collection device X.
[0051] As Figure 6As shown, the central region of the micro-porous plate 300 in the flat wire motor stator coating device can be provided with a connecting through hole c1, and the dust collection equipment X can include a first powder discharge pipe 600 and a dust collector 700, the first end of the first powder discharge pipe 600 can extend into the powder storage box 100 through the connecting through hole c1 of the micro-porous plate 300, part of the first powder discharge pipe 600 can be located in the connecting through hole c1, and the second end of the first powder discharge pipe 600 can be connected with the dust collector 700. In this way, when the flat wire motor stator coating device is working normally and the flat wire motor stator is being powder coated, the airflow generated by the synchronous working of the dust collector 700 forms negative pressure in the first powder discharge pipe 600, so that the excess coating powder can overflow from the opening of the first powder discharge pipe 600 and flow back into the dust collector 700; in addition, when the flat wire motor stator coating device is removed from the coating powder after the coating is completed, floating dust can also overflow from the opening of the first powder discharge pipe 600 and flow back into the dust collector 700. It should be noted that after the flat wire motor stator coating system is in a shutdown state, the operator needs to remove the residual coating powder in the powder storage box 100 to avoid affecting the subsequent use due to the deterioration of the coating powder.
[0052] As shown in the example, Figure 6 As shown, part of the first powder discharge pipe 600 can be located in the static pressure chamber 200, and the first end of the first powder discharge pipe 600 can be inserted into the connecting through hole c1 of the micro-porous plate 300 from the static pressure chamber 200 and extend into the powder storage box 100 through the connecting through hole c1 of the micro-porous plate 300, and the second end of the first powder discharge pipe 600 can extend out of the static pressure chamber 200 and be connected with the dust collector 700.
[0053] In this application, please refer to Figure 6 and Figure 7 , Figure 7Figure 1 is a schematic diagram of a first powder discharge pipe and a microplate according to an embodiment of the present application. The first powder discharge pipe 600 can include a horn pipe 601 and a powder guide pipe 602. The horn pipe 601 can be inserted into a connecting through hole c1 in the microplate 300. A first end of the horn pipe 601, which is away from the powder guide pipe 602, can extend into the powder storage box 100. A first end of the powder guide pipe 602, which is away from the horn pipe 601, can be connected to a dust collector 700. A second end of the horn pipe 601 and a second end of the powder guide pipe 602 are detachably connected. In this case, the first end of the horn pipe 601, which is away from the powder guide pipe 602, is tapered, and the inner diameter of the first end of the horn pipe 601 gradually increases in a direction away from the powder guide pipe 602. In this way, the excess powder in the powder storage box 100 can be more conveniently discharged into the dust collector 700 through the horn pipe 601. The horn pipe 601 and the powder guide pipe 602 are detachably connected, so that when the flat wire motor stator coating device is in a shutdown state, the operator can pull out the horn pipe 601, and the residual coating powder in the powder storage box 100 can be directly discharged into the dust collector 700 through the powder guide pipe 602, thereby avoiding the deterioration of the coating powder and affecting the subsequent use.
[0054] In the present application, as shown in Figure 6 , the flat wire motor stator coating system can further include a first air volume adjusting valve 800 arranged on the powder guide pipe 602. The first air volume adjusting valve 800 is used to adjust the flow rate of the gas passing through the powder guide pipe 602.
[0055] Optionally, as shown in Figure 7 , the inclination angle a of the inner side wall of the first end of the horn pipe 601 can range from 10 degrees to 35 degrees.
[0056] In the present embodiment, the second end of the horn pipe 601, which is away from the powder guide pipe 602, can have a first magnet (not shown in the figure), and the second end of the powder guide pipe 602, which is away from the horn pipe 601, can have a second magnet (not shown in the figure) magnetically connected to the first magnet. In this way, after the second end of the horn pipe 601 and the second end of the powder guide pipe 602 are in contact, they can be tightly connected through the magnetic attraction of the two magnets. It should be noted that the first magnet and the second magnet can both be permanent magnets. It should also be noted that in other possible implementations, the second end of the horn pipe 601 and the second end of the powder guide pipe 602 can also be connected through flanges or clamps.
[0057] Optionally, as shown in Figure 6As shown, the flat wire motor stator coating system can further include a second powder discharge pipe 900, two ends of the second powder discharge pipe 900 can be connected with the side wall of the powder storage box 100 and the dust collector 700 respectively. In this case, by connecting the second powder discharge pipe 900 with the side wall of the powder storage box 100, the floating dust brought out by the flat wire motor stator A can be further sucked into the dust collector 700 through the second powder discharge pipe 900, further improving the dust removal effect of the floating dust. In the present application, the flat wire motor stator coating system can further include a second air volume adjusting valve 1000 arranged on the second powder discharge pipe 900, which is used to adjust the flow of gas passing through the second powder discharge pipe 900.

[0059] The above description is only an optional embodiment of the present application, and is not used to limit the present application.
