[0060] In an exemplary embodiment, please refer to Figures 1 and 2. The present application provides a demagnetization control method, which is applied to a demagnetization module. Figure 2 is a structural schematic diagram of the demagnetization module in the present application. The demagnetization module includes a main body 11, a rotor base 12 and a demagnetization component 13 respectively located on the main body 11. The rotor base is used to set the rotor 2, and the rotor 2 includes a plurality of magnetic poles 21. The demagnetization control method includes steps S101 to S103. The following embodiments are described by taking the demagnetization control method applied to a host computer as an example.

[0061] S101: Acquire current position information of a target magnetic pole in the rotor and initial position information of a magnetizing and demagnetizing component; wherein the target magnetic pole is one of a plurality of magnetic poles.

[0062] It can be understood that before performing the magnetization and demagnetization operation on each magnetic pole 21 on the rotor 2, a position sensor can be installed on each magnetic pole 21, and a position sensor can also be installed on the magnetization and demagnetization assembly 13, and a three-dimensional coordinate system is established with the center point of the rotor as the origin. The X coordinate axis of the three-dimensional coordinate system extends along the first direction, the Y coordinate axis extends along the second direction, and the Z coordinate axis extends along the third direction. The first direction, the second direction and the third direction intersect. The three-dimensional coordinate system shown in FIG2 is only 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 magnetization and demagnetization coil. In an example, please refer to Figures 3 and 4. Figure 3 shows the position of the center point P when the magnetic pole 21 is located at the first magnetization position in an example, and Figure 4 shows the position of the center point A when the demagnetization coil is located at the second magnetization position in an example. It should be noted that the demagnetization coil has a certain thickness. The center point A of the demagnetization coil is not only at the center of the demagnetization coil in the XOZ plane, but also at the center of the demagnetization coil in the second direction, that is, the thickness direction of the demagnetization 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 beginning of the magnetization work, the relevant staff 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 each position sensor.

[0064] S102: Controlling the rotor to rotate on the rotor base according to the current position information, so that the target magnetic pole rotates to a first magnetizing position, and obtaining first magnetizing position information when the target magnetic pole is at the first magnetizing position.

[0065] After obtaining the current position information of the target magnetic pole and the initial position information of the charging and demagnetization component 13, the host computer can calculate the rotation angle of the target magnetic pole according to 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 and demagnetization component 13. After the target magnetic pole rotates to the first magnetization position, the position sensor can obtain the position information of the target magnetic pole again, that is, the first magnetization position information of the target magnetic pole when it is in the first magnetization position, and send the first magnetization position information to the host computer.

[0066] S103: According to the first magnetization position information and the initial position information, control the magnetization and demagnetization assembly 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 and demagnetization assembly; wherein the distance between the second magnetization position and the first magnetization position satisfies a preset magnetization condition.

[0067] After the target magnetic pole rotates to the first magnetizing position, it is necessary to control the movement of the demagnetizing component 13 so that the target magnetic pole is embedded in the demagnetizing coil on the demagnetizing component 13, so that the demagnetizing coil magnetizes the target magnetic pole. Specifically, the host computer can calculate the moving direction and moving distance of the demagnetizing component 13 according to the first magnetizing position information of the target magnetic pole and the initial position information of the demagnetizing component 13, and control the demagnetizing component 13 to move to the second magnetizing position on the body 11. In addition, the distance between the second magnetizing position and the first magnetizing position meets the preset magnetizing condition, that is, after the target magnetic pole rotates to the first magnetizing position and the demagnetizing component 13 moves to the second magnetizing position, the target magnetic pole can be embedded in the demagnetizing component 13, please refer to Figure 5, it can be seen that after the alignment control of the present application, the target magnetic pole can be just embedded in the demagnetizing component 13, and the target magnetic pole and the demagnetizing component 13 will not be damaged by collision or the like.

[0068] The above-mentioned demagnetization control method first obtains the current position information of the target magnetic pole in the rotor and the initial position information of the demagnetization component, controls the rotor to rotate on the rotor base according to the current position information of the target magnetic pole, so that the target magnetic pole rotates to the first magnetization position, then obtains the first magnetization position information of the target magnetic pole when it is in the first magnetization position, controls the demagnetization component to move to the second magnetization position on the body according to the first magnetization position information and the initial position information, so that the target magnetic pole is magnetized and / or demagnetized by the demagnetization component, and the distance between the second magnetization position and the first magnetization position meets the preset magnetization condition. Through the demagnetization control method of the present application, there is no need to magnetize each permanent magnet block before assembling it, thereby avoiding the mutual force in the permanent magnet block assembly process endangering the safety of the staff. At the same time, the demagnetization control method of the present application can control the target magnetic pole and the demagnetization component to move to the corresponding position for magnetization or demagnetization according to the current position of the target magnetic pole and the initial position of the demagnetization component, which can improve the efficiency of magnetization or demagnetization.

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

[0070] Please refer to FIG. 6 , step S102 , controlling the rotor to rotate on the rotor base according to the current position information so that the target magnetic pole rotates to the first magnetizing position, including step S601 and step S602 .

[0071] S601: Determine a rotation angle according to a first initial coordinate, a second initial coordinate and a preset angle.

[0072] In the application, the demagnetization 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 drive the rotor to rotate under the control of the host computer. The second drive motor and the third drive motor are connected to the demagnetization component. The second drive motor is used to drive the demagnetization component to move in the second direction under the control of the host computer. The third drive motor is used to drive the demagnetization component to move in the third direction under the control of the host computer. When the first drive motor drives the rotor to rotate, it specifically drives the rotor to rotate around the rotation axis of the rotor base. The rotation axis can be a physical structure or a virtual structure. When the rotation axis is a virtual structure, the rotation axis can be equivalent to the Z axis of the three-dimensional coordinate system.

[0073] The coordinates of each point on the rotating axis on the X-axis are all 0, and the distance between the charging and demagnetizing coil and the rotating axis in the first direction, that is, the X-axis direction, is less than or equal to the preset first distance threshold. Exemplarily, the distance between the charging and demagnetizing coil and the rotating axis in the first direction is equal to the preset first distance threshold, and the preset first distance threshold can be 0, that is, the coordinates of the charging and demagnetizing coil on the X-axis are 0.

[0074] In order to enable the target magnetic pole to rotate to the position facing the charging and demagnetizing coil, the coordinate of the target magnetic pole on the X-axis needs to be controlled to be 0. Specifically, when the coordinate of the target magnetic pole on the X-axis is 0, the target projection angle of the target magnetic pole in the Z-axis direction is 0°, that is, the preset angle It can be 0°. Assuming that 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 the application, the actual projection angle of the target magnetic pole in the Z-axis direction can be determined according to the first initial coordinate x0, the second initial coordinate y0 and the first preset formula. , the first preset formula can be Then, you can adjust the projection angle according to the actual projection angle. With preset angle The difference determines the angle of rotation of the rotor.

[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 a first magnetizing position, and the distance between the coordinate position of the first magnetizing position in the first direction and the rotation axis is less than or equal to a first distance threshold.

[0077] After calculating the rotation angle of the rotor, the host computer can control the first drive motor to drive the rotor to rotate according to the calculated rotation angle. After the rotation is completed, the position of the target magnetic pole is the first magnetization position. The coordinate of the target magnetic pole on the X-axis at the first magnetization position is 0, thereby realizing that the first magnetization position of the target magnetic pole is aligned with the rotation axis in the first direction, and then realizing that the first magnetization position of the target magnetic pole is aligned with the demagnetization component in the first direction in the first direction. In addition, when the target magnetic pole rotates to the first magnetization position, the position sensor on the target magnetic pole will detect the first magnetization position information of the target magnetic pole at the first magnetization position again, and send the first magnetization position information to the host computer, that is, update the coordinate information of point P, assuming that the first magnetization position information is P (x0*, y0*, z0*), where x0*=0, z0*=z0, and the size of y0* and z0* is determined by the position sensor.

[0078] In an exemplary embodiment, please refer to FIG. 7 , step S103 , according to the first magnetization position information and the initial position information, controlling the magnetization and demagnetization assembly to move to the second magnetization position on the body, including steps S701 to S703 .

[0079] S701: Determine second magnetization position information of a magnetization and demagnetization component according to first magnetization position information and 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 demagnetization component according to the first magnetization position information and the preset magnetization condition. The preset magnetization condition is used to indicate that the demagnetization component is aligned with the target magnetic pole in the first direction and the third direction, and the distance in the second direction can satisfy that the target magnetic pole can be embedded in the demagnetization coil for magnetization without collision and damage.

[0081] S702: Determine a target moving vector of the magnetizing and demagnetizing component according to the second magnetizing position information and the initial position information.

[0082] After the second magnetization position information of the magnetization and demagnetization component is determined, the magnetization and demagnetization component can be controlled to move from the initial position to the second magnetization position according to the target moving vectors in each direction of the second magnetization position information and the initial position information.

[0083] S703: Control the magnetization and demagnetization assembly to move to a 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 has been aligned with the 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 direction and the third direction, that is, the target movement vector of the demagnetization component, to control the 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 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. Assuming that the initial position information of the demagnetization component is A (x1, y1, z1), the second magnetization position information is A (x1*, y1*, z1*).

[0086] Please refer to FIG. 8 , step S701 , determining the second magnetization position information of the magnetization and demagnetization component according to the first magnetization position information and the preset magnetization condition, including steps S801 to S803 .

[0087] S801: Determine a coordinate interval of the charging and demagnetization component in the second direction according to first magnetization position information and preset coil thickness information of the charging and demagnetization coil in the second direction.

[0088] It can be understood that the charging and demagnetization coil has a certain thickness h in the second direction so that the magnetic pole can be embedded in the charging and demagnetization coil. To ensure that the target magnetic pole can be smoothly embedded in the charging and demagnetization coil and the charging and demagnetization coil can smoothly magnetize the target magnetic pole, the target magnetic pole and the charging and demagnetization coil in the second direction must meet the following conditions:

[0089] That is, the coordinate interval of the demagnetization component in the second direction needs to be calculated according to the coordinate of the target magnetic pole in the second direction at the first magnetization position and the coil thickness information h of the preset demagnetization coil in the second direction. The coordinate interval is .

[0090] S802: Determine a first target coordinate of the charging and demagnetizing component in the second direction according to the coordinate interval.

[0091] After the coordinate interval of the charging and demagnetization coil in the second direction is determined, any value in the coordinate interval can be selected as the first target coordinate y1* of the charging and demagnetization assembly in the second direction.

[0092] S803: Determine a second target coordinate of the charging and demagnetizing component in the third direction according to the first magnetization position information.

[0093] In order to enable the target magnetic pole to be smoothly embedded in the charging and demagnetization coil, it is also necessary to control the alignment of the target magnetic pole and the charging and demagnetization 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 demagnetization 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 demagnetization component in the third direction can also be determined according to the coordinate z0 of the target magnetic pole in the third direction before controlling the rotor to rotate.

[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. Referring to FIG. 9 , step S702 , determining a target moving vector of the magnetizing and demagnetizing assembly according to the second magnetizing position information and the initial position information, includes steps S901 and S902 .

[0095] S901: Determine a first moving vector of the charging and demagnetizing component in a second direction according to the third initial coordinate and the first target coordinate.

[0096] In applications, the first moving vector of the charging and demagnetizing component in the second direction may be determined according to the difference between the third initial coordinate y1 and the first target coordinate y1*.

[0097] S902: Determine a second moving vector of the charging and demagnetizing component in the third direction according to the fourth initial coordinate and the second target coordinate.

[0098] Similarly, the second moving vector of the charging and demagnetizing assembly in the third direction may be determined according to the difference between the fourth initial coordinate z1 and the second target coordinate z1*.

[0099] In an exemplary embodiment, referring to FIG. 10 , the charging and demagnetization control method further includes steps S1001 to S1004 .

[0100] S1001: When the magnetization of the target magnetic pole is completed, the demagnetization assembly is controlled to move to a standby position on the main body according to a first preset movement vector.

[0101] The distance between the rotor and the demagnetization component at the standby position meets the preset distance condition. When the target magnetic pole is magnetized, the next target magnetic pole can be magnetized. First, the demagnetization component needs to be controlled to move to the standby position according to the first preset moving vector to separate the target magnetic pole from the demagnetization component. The direction of the first preset moving vector is the direction away from the rotor on the Y axis.

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

[0103] Then, the relevant staff 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 magnetizing position.

[0105] Similarly, the rotor can be controlled to a position where the projection angle of the next target magnetic pole in the Z-axis direction is 0°, that is, the first magnetizing position, according to the current position information of the next target magnetic pole.

[0106] S1004: Controlling the charging and demagnetizing assembly to move from the standby position to the second magnetizing position on the main body according to the second preset movement vector, so as to magnetize and / or demagnetize the target magnetic pole through the charging and demagnetizing assembly.

[0107] When the next target magnetic pole reaches the first magnetizing position, the demagnetizing component can be controlled to move from the standby position back to the second magnetizing position. The second preset movement vector has the same value as the first preset movement vector but has an opposite direction, that is, the direction of the second preset movement vector is the direction on the Y-axis close to the rotor.

[0108] In the application, the upper computer can include multiple control modes when controlling the charging and demagnetization module. For example, it can include four control modes: "automatic / local" mode, "manual / local" mode, "remote" mode and "position correction" mode.

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

[0110] In the "Remote" mode, the host computer can display the current position of the rotor and the magnetizing coil in real time. The host computer can obtain the relative position offset information that the rotor and the magnetizing coil need to move, that is, the angle of rotation 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. The relevant technicians can directly remotely control the rotor and the magnetizing coil to execute the movement through the "Execute" option.

[0111] In the "manual" mode, the host computer can display the current position of the rotor and magnetizing coil in real time. The relevant technicians can adjust the position of the rotor or magnetizing coil with the minimum step length through the host computer. In one example, the minimum movement step length of the rotor is 0.1 degrees, and the movement step length of the magnetizing coil in the second and third directions is 0.1mm.

[0112] In the "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 position 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.
