[0060] In one exemplary embodiment, please refer to Figure 1 and Figure 2 This application provides a charging / demagnetizing control method, applied to a charging / demagnetizing module. Figure 2 This is a schematic diagram of the charging and demagnetizing module in this application. The charging and demagnetizing module includes a body 11, a rotor base 12 located on the body 11, and a charging and demagnetizing assembly 13. The rotor base is used to set the rotor 2. The rotor 2 includes multiple magnetic poles 21. The charging and demagnetizing control method includes steps S101 to S103. The following embodiment uses the application of the charging and demagnetizing control method to a host computer as an example for illustration.

[0061] S101: Obtain the current position information of the target magnetic pole in the rotor and the initial position information of the charging and demagnetizing components; wherein, the target magnetic pole is one of multiple magnetic poles.

[0062] It is understandable that before performing the charging and demagnetizing operations on each magnetic pole 21 of the rotor 2, a position sensor can be installed on each magnetic pole 21, and a position sensor can also be installed on the charging and demagnetizing assembly 13. A three-dimensional coordinate system is established with the center point of the rotor as the origin. The X-axis of this three-dimensional coordinate system extends along a first direction, the Y-axis extends along a second direction, and the Z-axis extends along a third direction. The first direction, the second direction, and the third direction intersect. Figure 2 The three-dimensional coordinate system shown is merely an example and does not represent the actual position of the three-dimensional coordinate system in this application. The position sensor can detect the coordinate position of the center point of each magnetic pole 21, as well as the coordinate position of the center point of the charging / demagnetizing coil. For an example, please refer to... Figure 3 and Figure 4 , Figure 3 This is the position of the center point P when magnetic pole 21 is in the first magnetization position in an example. Figure 4In one example, the center point A of the charging / demagnetizing coil is located in the second charging position. It should be noted that the charging / demagnetizing coil has a certain thickness. The center point A of the charging / demagnetizing coil is not only located at the center of the charging / demagnetizing coil in the XOZ plane, but also at the center of the charging / demagnetizing coil in the second direction, that is, the thickness direction of the charging / demagnetizing coil. Similarly, the center point P of the magnetic pole 21 is also the center of the magnetic pole in three directions.

[0063] At the start of the magnetization process, relevant personnel can select a magnetic pole as the target magnetic pole through the host computer, and obtain the current position information of the target magnetic pole and the initial position information of the magnetization and demagnetization components through various position sensors.

[0064] S102: Control the rotor to rotate on the rotor base according to the current position information so that the target magnetic pole rotates to the first magnetization position, and obtain the first magnetization position information of the target magnetic pole at the first magnetization position.

[0065] After obtaining the current position information of the target magnetic pole and the initial position information of the charging / demagnetizing component 13, the host computer can calculate the rotation angle of the target magnetic pole based on the current position information of the target magnetic pole, and control the rotor to rotate on the rotor base so that the target magnetic pole faces the charging / demagnetizing component 13. After the target magnetic pole rotates to the first charging position, the position sensor can obtain the position information of the target magnetic pole again, that is, the first charging position information of the target magnetic pole at the first charging position, and send the first charging position information to the host computer.

[0066] S103: Based on the first magnetization position information and the initial position information, control the magnetization / demagnetization component to move to the second magnetization position on the main body, so as to magnetize and / or demagnetize the target magnetic pole through the magnetization / demagnetization component; wherein, the distance between the second magnetization position and the first magnetization position satisfies the preset magnetization condition.

[0067] After the target magnetic pole rotates to the first magnetization position, the magnetization / demagnetization assembly 13 needs to be moved to embed the target magnetic pole into the magnetization / demagnetization coil on the assembly 13, thus magnetizing the target magnetic pole. Specifically, the host computer can calculate the moving direction and distance of the magnetization / demagnetization assembly 13 based on the first magnetization position information of the target magnetic pole and the initial position information of the assembly 13, and control the assembly 13 to move to the second magnetization position on the body 11. Furthermore, the distance between the second magnetization position and the first magnetization position satisfies a preset magnetization condition, meaning that after the target magnetic pole rotates to the first magnetization position and the assembly 13 moves to the second magnetization position, the target magnetic pole can be embedded in the assembly 13. Please refer to [link to relevant documentation]. Figure 5 As can be seen, through the alignment control of this application, the target magnetic pole can be perfectly embedded in the charging and demagnetizing component 13, and the target magnetic pole and the charging and demagnetizing component 13 will not be damaged by collision or knocking.

[0068] The above-described magnetization control method first acquires the current position information of the target magnetic pole in the rotor and the initial position information of the magnetization / demagnetization assembly. Based on the current position information of the target magnetic pole, the rotor is controlled to rotate on the rotor base so that the target magnetic pole rotates to the first magnetization position. Then, the first magnetization position information of the target magnetic pole at the first magnetization position is acquired. Based on the first magnetization position information and the initial position information, the magnetization / demagnetization assembly is controlled to move on the main body to the second magnetization position so as to magnetize and / or demagnetize the target magnetic pole through the magnetization / demagnetization assembly. The distance between the second magnetization position and the first magnetization position meets the preset magnetization conditions. The magnetization / demagnetization control method of this application does not require magnetizing each permanent magnet block before assembly, avoiding the interaction force during the assembly process of permanent magnet blocks from endangering the safety of workers. At the same time, the magnetization / demagnetization control method of this application can control the target magnetic pole and the magnetization / demagnetization assembly to move to the corresponding position for magnetization or demagnetization based on the current position of the target magnetic pole and the initial position of the magnetization / demagnetization assembly, which can improve the efficiency of magnetization or demagnetization.

[0069] In an exemplary embodiment, the charging / demagnetizing assembly includes a charging / demagnetizing coil. The distance between the charging / demagnetizing coil and the rotor's rotation axis on the rotor base in a first direction is less than or equal to a preset first distance threshold. The current position information includes a first initial coordinate in the first direction and a second initial coordinate in the second direction. The rotation axis extends along a third direction, and the first direction, the second direction, and the third direction intersect each other.

[0070] Please see Figure 6 Step S102 involves controlling the rotor to rotate on the rotor base based on the current position information, so that the target magnetic pole rotates to the first magnetization position, including steps S601 and S602.

[0071] S601: Determine the rotation angle based on the first initial coordinates, the second initial coordinates, and the preset angle.

[0072] In applications, the magnetizing / demagnetizing module may further include a first drive motor, a second drive motor, and a third drive motor. The first drive motor is connected to the rotor base and is used to drive the rotor base to rotate the rotor under the control of the host computer. The second and third drive motors are connected to the magnetizing / demagnetizing assembly. The second drive motor is used to drive the magnetizing / demagnetizing assembly to move in a second direction under the control of the host computer, and the third drive motor is used to drive the magnetizing / demagnetizing assembly to move in a third direction under the control of the host computer. When the first drive motor drives the rotor to rotate, specifically, it drives the rotor to rotate around the rotation axis of the rotor base. This rotation axis can be a solid structure or a virtual structure. In the case of a virtual structure, the rotation axis can be equivalent to the Z-axis of a three-dimensional coordinate system.

[0073] In this configuration, the coordinates of all points on the rotation axis on the X-axis are 0, and the distance between the charging / demagnetizing coil and the rotation axis in the first direction, i.e., the X-axis direction, is less than or equal to a preset first distance threshold. For example, the distance between the charging / demagnetizing coil and the rotation axis in the first direction is equal to the preset first distance threshold, which can be 0, meaning the coordinate of the charging / demagnetizing coil on the X-axis is 0.

[0074] To ensure the target magnetic pole can rotate to a position facing the charging / demagnetizing coil, its X-axis coordinate must also be set to 0. Specifically, when the target magnetic pole's X-axis coordinate is 0, its projection angle along the Z-axis is 0°, which is the preset angle. It can be 0°. Assuming the midpoint of the target magnetic pole is P, the current position information is the coordinate information of point P, and the coordinates of P are (x0, y0, z0), where x0 is the first initial coordinate of the midpoint P of the target magnetic pole in the first direction, and y0 is the second initial coordinate of the midpoint P of the target magnetic pole in the second direction.

[0075] In application, the actual projection angle of the target magnetic pole along the Z-axis can be determined based on the first initial coordinate x0, the second initial coordinate y0, and the first preset formula. The first preset formula can be Then, based on the actual projection angle With preset angle The difference determines the rotor's rotation angle.

[0076] S602: Control the rotor to rotate around the rotation axis on the rotor base according to the rotation angle so that the target magnetic pole rotates to the first magnetization position. The distance between the first magnetization position and the rotation axis in the first direction is less than or equal to the first distance threshold.

[0077] After calculating the rotor's rotation angle, the host computer can control the first drive motor to drive the rotor to rotate according to the calculated rotation angle. After rotation, the position of the target magnetic pole is the first magnetization position. The X-axis coordinate of the target magnetic pole at the first magnetization position is 0, thus aligning the first magnetization position of the target magnetic pole with the rotation axis in the first direction, and further aligning the first magnetization position of the target magnetic pole with the magnetization / demagnetization assembly in the first direction. Furthermore, after the target magnetic pole rotates to the first magnetization position, the position sensor on the target magnetic pole will again detect the first magnetization position information of the target magnetic pole at the first magnetization position and send the first magnetization position information to the host computer, i.e., update the coordinate information of point P. Assuming the first magnetization position information is P(x0*, y0*, z0*), where x0*=0, z0*=z0, and the values ​​of y0* and z0* are determined by the position sensor.

[0078] In one exemplary embodiment, please refer to Figure 7 Step S103, based on the first magnetization position information and the initial position information, controls the magnetization / demagnetization component to move to the second magnetization position on the body, including steps S701 to S703.

[0079] S701: Determine the second magnetization position information of the magnetization / demagnetization component based on the first magnetization position information and the preset magnetization conditions.

[0080] After the target magnetic pole moves to the first magnetization position, the host computer can determine the second magnetization position information of the magnetization / demagnetization assembly based on the first magnetization position information and the preset magnetization conditions. The preset magnetization conditions are used to instruct the magnetization / demagnetization assembly to align with the target magnetic pole in the first direction and the third direction, and the distance in the second direction is sufficient to allow the target magnetic pole to be embedded in the magnetization / demagnetization coil for magnetization without collision or damage.

[0081] S702: Determine the target movement vector of the magnetization / demagnetization assembly based on the second magnetization position information and the initial position information.

[0082] After determining the second magnetization position information of the magnetization / demagnetization component, the magnetization / demagnetization component can be controlled to move from the initial position to the second magnetization position based on the target movement vector in each direction according to the second magnetization position information and the initial position information.

[0083] S703: Control the magnetization / demagnetization assembly to move to the second magnetization position on the main body according to the target movement vector.

[0084] Specifically, since the first magnetization position of the target magnetic pole is already aligned with the magnetization / demagnetization component in the first direction, it is only necessary to calculate the distance difference between the second magnetization position information and the initial position information in the second and third directions, i.e. the target movement vector of the magnetization / demagnetization component, to control the magnetization / demagnetization component to move to the second magnetization position.

[0085] In an exemplary embodiment, the first magnetization position information is used to indicate the coordinate information of the midpoint of the target magnetic pole, and the second magnetization position information is used to indicate the coordinate information of the midpoint of the magnetization and demagnetization coil. The second magnetization position information includes the first target coordinate in the second direction and the second target coordinate in the third direction. It is assumed that the initial position information of the magnetization and demagnetization component is A(x1, y1, z1), and the second magnetization position information is A(x1*, y1*, z1*).

[0086] Please see Figure 8 Step S701, determining the second magnetization position information of the magnetization and demagnetization assembly based on the first magnetization position information and the preset magnetization conditions, including steps S801 to S803.

[0087] S801: Determine the coordinate range of the magnetizing / demagnetizing assembly in the second direction based on the first magnetizing position information and the preset coil thickness information of the magnetizing / demagnetizing coil in the second direction.

[0088] It is understood that the charging / demagnetizing coil has a certain thickness h in the second direction so that the magnetic pole can be embedded in the charging / demagnetizing coil. In order to ensure that the target magnetic pole can be successfully embedded in the charging / demagnetizing coil and that the charging / demagnetizing coil can successfully magnetize the target magnetic pole, the target magnetic pole and the charging / demagnetizing coil must satisfy the following in the second direction:

[0089] That is, the coordinate range of the charging / demagnetizing assembly in the second direction needs to be calculated based on the coordinates of the target magnetic pole at the first magnetization position in the second direction and the preset coil thickness information h of the charging / demagnetizing coil in the second direction. The coordinate range is... .

[0090] S802: Determine the first target coordinate of the charging / demagnetizing assembly in the second direction based on the coordinate range.

[0091] After determining the coordinate range of the charging / demagnetizing coil in the second direction, any value can be selected from the coordinate range as the first target coordinate y1* of the charging / demagnetizing component in the second direction.

[0092] S803: Determine the second target coordinates of the magnetization / demagnetization component in the third direction based on the first magnetization position information.

[0093] To ensure that the target magnetic pole can be successfully embedded into the charging and demagnetizing coil, it is also necessary to control the alignment of the target magnetic pole and the charging and demagnetizing coil in the third direction. Specifically, the coordinate z0* of the target magnetic pole in the third direction can be directly determined as the second target coordinate of the charging and demagnetizing component in the third direction. In application, since the coordinate of the target magnetic pole in the third direction does not change, the second target coordinate of the charging and demagnetizing component in the third direction can also be determined based on the coordinate z0 of the target magnetic pole in the third direction before controlling the rotor rotation.

[0094] In an exemplary embodiment, the initial position information includes a third initial coordinate y1 in the second direction and a fourth initial coordinate z1 in the third direction. See also... Figure 9 Step S702 involves determining the target movement vector of the magnetization / demagnetization component based on the second magnetization position information and the initial position information, including steps S901 and S902.

[0095] S901: Determine the first movement vector of the charging / demagnetizing assembly in the second direction based on the third initial coordinates and the first target coordinates.

[0096] In application, the first movement vector of the charging / demagnetizing component in the second direction can be determined based on the difference between the third initial coordinate y1 and the first target coordinate y1*.

[0097] S902: Determine the second movement vector of the charging / demagnetizing component in the third direction based on the fourth initial coordinate and the second target coordinate.

[0098] Similarly, the second movement vector of the charging / demagnetizing component in the third direction can be determined based on the difference between the fourth initial coordinate z1 and the second target coordinate z1*.

[0099] In one exemplary embodiment, please refer to Figure 10 The charging and demagnetizing control method also includes steps S1001 to S1004.

[0100] S1001: When the target magnetic pole is magnetized, the magnetization and demagnetization components are moved to the standby position on the main body according to the first preset movement vector.

[0101] The distance between the rotor and the charging / demagnetizing assembly in the standby position meets a preset distance condition. Once the target magnetic pole is magnetized, preparations can be made to magnetize the next target magnetic pole. First, the charging / demagnetizing assembly needs to be controlled to move to the standby position according to the first preset movement vector so that the target magnetic pole is separated from the charging / demagnetizing assembly. The direction of the first preset movement vector is the direction away from the rotor on the Y-axis.

[0102] S1002: Obtain the current position information of the next target magnetic pole in the rotor.

[0103] Then, relevant personnel can select the next target magnetic pole through the host computer and obtain the current position information of the next target magnetic pole through the position sensor on the next target magnetic pole.

[0104] S1003: Control the rotor to rotate on the rotor base according to the current position information so that the target magnetic pole rotates to the first magnetization position.

[0105] Similarly, the rotor can be controlled to the position where the projection angle of the next target magnetic pole in the Z-axis direction is 0°, i.e., the first magnetization position, based on the current position information of the next target magnetic pole.

[0106] S1004: According to the second preset movement vector, the charging and demagnetizing component moves from the standby position to the second charging position on the main body, so as to charge and / or demagnetize the target magnetic pole through the charging and demagnetizing component.

[0107] When the next target magnetic pole reaches the first magnetization position, the magnetization and demagnetization components can be controlled to move back to the second magnetization position from the standby position. The second preset movement vector has the same value as the first preset movement vector, but the opposite direction. That is, the direction of the second preset movement vector is the direction on the Y-axis closer to the rotor.

[0108] In applications, when the host computer controls the charging and demagnetizing module, it can include multiple control modes. For example, it can include four control modes: "automatic / local" mode, "manual / local" mode, "remote" mode, and "position correction" mode.

[0109] In "Automatic / Local" mode, the host computer can display the current position of the rotor and magnetizing coil in real time. Relevant technicians can set the relative position offset of the rotor and magnetizing coil to be moved. After clicking the "Start" button, the rotor and magnetizing coil will move to the set position respectively.

[0110] In "Remote" mode, the host computer can display the current position of the rotor and magnetizing coil in real time. The host computer can obtain the relative position offset information of the rotor and magnetizing coil that need to move, that is, the rotation angle required for the target magnetic pole in the rotor to move to the first magnetizing position and the movement vector of the magnetizing coil in the second and third directions. Relevant technicians can directly remotely control the rotor and magnetizing coil to perform the movement through the "Execute" option.

[0111] In "Manual" mode, the host computer can display the current positions of the rotor and magnetizing coil in real time. Technical personnel can adjust the rotor or magnetizing coil position using the host computer in minimum step sizes. In one example, the minimum rotor movement step size is 0.1 degrees, and the magnetizing coil movement step size is 0.1 mm in both the second and third directions.

[0112] In "position correction" mode, the host computer can display the current position of the rotor and magnetizing coil in real time. Relevant technicians can directly set the required positions of the rotor and magnetizing coil through the human-machine interface to meet the overall magnetizing and demagnetizing operation requirements of permanent magnet fan rotors with different diameter parameters.
