[0039] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the following detailed description, for the sake of explanation, numerous specific details are set forth in order to provide a comprehensive understanding of the embodiments of the present disclosure. However, obviously, one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily obscuring the concepts of the present disclosure.

[0040] The terms used herein are merely for describing specific embodiments and are not intended to limit the present disclosure. The terms "including", "comprising", etc. used herein indicate the presence of the described features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0041] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0042] In the case of using expressions such as "at least one of A, B, and C, etc.", generally, it should be interpreted according to the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include, but is not limited to, a system having only A, only B, only C, having A and B, having A and C, having B and C, and / or having A, B, and C, etc.).

[0043] During the magnet measurement process, the positioning and collimation accuracy of the magnet play a crucial role in the magnetic field measurement accuracy. The related technology is to use a laser tracker to position and collimate the magnet. Since the highest measurement accuracy of the laser tracker is 15um + 6um / m, however, for magnets with a positioning and collimation requirement less than 15um, using a laser tracker can no longer meet the positioning and collimation requirements.

[0044] An embodiment of the present disclosure provides a magnet collimation method, which is applied to a magnet collimation system. The magnet collimation system includes a Hall point measurement platform, a coordinate measuring machine, and a laser tracker. The magnet to be collimated is placed on the coordinate measuring machine. The method includes: obtaining a first set of coordinate values of the target of the magnet to be collimated measured by the coordinate measuring machine in the mechanical coordinate system of the magnet to be collimated; adjusting the coordinate system of the laser tracker to make the coordinate system of the laser tracker consistent with the coordinate system of the Hall point measurement platform; importing the first set of coordinate values into the laser tracker software to obtain a deviation value, where the deviation value is the difference between the first set of coordinate values and a second set of coordinate values, and the second set of coordinate values is the coordinate value of the current position of the magnet to be collimated; taking the condition that the deviation value meets a preset condition as the adjustment target, and adjusting the position of the magnet to be collimated to change the second set of coordinate values to achieve the collimation of the magnet to be collimated. The combined measurement of the coordinate measuring machine and the laser tracker is used to realize the collimation positioning during the magnet magnetic measurement process, which can not only meet the positioning accuracy but also improve the measurement efficiency.

[0045] Figure 1 FIG. schematically shows a flowchart of the magnet collimation method according to an embodiment of the present disclosure.

[0046] As Figure 1 shown, the magnet collimation method includes operations S110 - S140.

[0047] In operation S110, in the mechanical coordinate system A1 of the magnet to be collimated, a first set of coordinate values P1 of the target of the magnet to be collimated measured by the coordinate measuring machine is obtained.

[0048] In some embodiments, the coordinate measuring machine is used to establish the mechanical coordinate system A1 of the magnet to be collimated. According to the mechanical coordinate system of the magnet to be collimated, the first set of coordinate values P1 of the magnet target is determined. The first set of coordinate values P1 of the magnet target may be the coordinate values of multiple points in the mechanical coordinate system of the magnet to be collimated, such as 4 to 8 points. These points may be specific marks or geometric features on the magnet, and the number of magnet targets to be collimated is different.

[0049] In operation S120, the coordinate system A2 of the laser tracker is adjusted to make the coordinate system A2 of the laser tracker consistent with the coordinate system A3 of the Hall point measurement platform.

[0050] In some embodiments, the coordinate measuring machine is used to establish the coordinate system A3 of the Hall point measurement platform according to the movement trajectory of the Hall point measurement platform.

[0051] Assume that the origin of the coordinate system of the Hall point measurement platform is located at the center of the platform, the X-axis is along the long side direction of the platform, the Y-axis is along the short side direction of the platform, and the Z-axis is perpendicular to the platform plane. By measuring the geometric features of the platform with the coordinate measuring machine, the parameters of the coordinate system A3 of the Hall point measurement platform are determined.

[0052] In some embodiments, the collimation magnet to be collimated is placed in the coordinate system A3 of the Hall point measurement platform. In the coordinate system A3 of the Hall point measurement platform, the coordinate values of any set of points are measured using a coordinate measuring machine to obtain a fourth set of coordinate values P4. In the coordinate system A2 of the laser tracker, the coordinate values of any set of points are measured using the laser tracker to obtain a fifth set of coordinate values P5.

[0053] Wherein, any set of points refers to any points in the coordinate system A3 of the Hall point measurement platform. In some embodiments, any set of points can be the target of the collimation magnet to be collimated.

[0054] In some embodiments, the fourth set of coordinate values P4 is used as the control network points of the laser tracker. Based on the fourth set of coordinate values P4 and the fifth set of coordinate values P5, the coordinate system A2 of the laser tracker is adjusted to make the coordinate system A2 of the laser tracker consistent with the coordinate system A3 of the Hall point measurement platform.

[0055] In operation S130, the first set of coordinate values P1 is imported into the laser tracker software to obtain a deviation value, which is the difference between the first set of coordinate values P1 and the second set of coordinate values P2. The second set of coordinate values P2 is the coordinate value of the current position of the collimation magnet.

[0056] In the laser tracker software, the origin of the coordinate system A2 of the laser tracker can be moved arbitrarily to make the mechanical coordinate system A1 of the collimation magnet, the coordinate system A2 of the laser tracker and the coordinate system A3 of the Hall point measurement platform consistent.

[0057] The second set of coordinate values P2 is the coordinate value of the current position of the collimation magnet in the coordinate system A2 measured by the laser tracker. After the laser tracker converts the first set of coordinate values P1 and the second set of coordinate values P2 to the same coordinate system, the deviation value is calculated.

[0058] In operation S140, with the deviation value meeting the preset conditions as the adjustment target, the position of the collimation magnet is adjusted to change the second set of coordinate values P2 to achieve the collimation of the collimation magnet.

[0059] In some embodiments, the second set of coordinate values P2 is adjusted through an adjustment device to make the deviation value approach zero. The preset condition is set that the absolute value of the deviation value is less than 0.1 mm. According to the calculated deviation value, a mechanical adjustment device (such as a lead screw, slider, etc.) is used to adjust the position of the collimation magnet to gradually reduce the deviation value. During the adjustment process, the second set of coordinate values is continuously measured by the laser tracker and the deviation value is calculated until the deviation value meets the preset conditions.

[0060] Figure 2 Schematically shows a flowchart of another magnet collimation method according to an embodiment of the present disclosure.

[0061] As Figure 2As shown, in addition to operations S110 - S140, the magnet collimation method further includes operation S150. With the deviation value meeting the preset conditions as the adjustment target, the position of the magnet to be collimated is adjusted to change the second set of coordinate values P2 to collimate the magnet to be collimated. After that, it further includes: obtaining the third set of coordinate values P3 of the current magnet target measured by the coordinate measuring machine in the Hall point measurement platform coordinate system A3; calculating whether the deviation value between the third set of coordinate values P3 and the first set of coordinate values P1 meets the preset conditions.

[0062] At this time, the measurement coordinate system of the coordinate measuring machine has the same direction as the Hall point measurement platform coordinate system, and the origin can be arbitrarily moved through the laser tracker software. Move the origin of the measurement coordinate system of the coordinate measuring machine to the mechanical center position of the magnet to be collimated and measure the magnet target again to verify the collimation accuracy.

[0063] In some embodiments, when the deviation value does not meet the preset conditions, operations S120 - S150 are performed again until the deviation value between the third set of coordinate values P3 and the first set of coordinate values P1 meets the preset conditions.

[0064] In some embodiments, the preset condition is less than 0.01 mm.

[0065] In some embodiments, when the preset conditions are met, it is confirmed that the collimation accuracy of the collimated magnet meets the preset conditions.

[0066] Figure 3 Schematically shows the structural diagram of a magnet collimation system according to an embodiment of the present disclosure.

[0068] The coordinate measuring machine 20, on which the magnet to be collimated 100 is placed, is used to obtain the first set of coordinate values P1 of the measured magnet target to be collimated in the mechanical coordinate system A1 of the magnet to be collimated.

[0071] The laser tracker 30 is used to provide the laser tracker coordinate system A2 and measure the second set of coordinate values P2 of the magnet to be collimated.

[0072] The calculation module is further configured to import the first set of coordinate values P1 into the laser tracker software to obtain a deviation value, where the deviation value is the difference between the first set of coordinate values P1 and the second set of coordinate values P2, and the second set of coordinate values P2 is the coordinate value of the current position of the collimator magnet 100.

[0073] The adjustment module is configured to adjust the position of the collimator magnet 100 with the condition that the deviation value meets a preset condition as the adjustment target, so as to change the second set of coordinate values P2 to achieve the collimation of the collimator magnet 100.

[0074] In some embodiments, the coordinate measuring machine 20 is further configured to obtain a third set of coordinate values P3 of the current magnet 100 target in the Hall point measurement platform coordinate system A3. The calculation module is further configured to calculate whether the deviation value between the third set of coordinate values P3 and the first set of coordinate values P1 meets a preset condition.

[0075] In some embodiments, when the deviation value does not meet the preset condition, the operation of adjusting the laser tracker coordinate system A2 again to make the laser tracker coordinate system A2 coincide with the Hall point measurement platform coordinate system A3 is performed until the deviation value between the third set of coordinate values P3 and the first set of coordinate values P1 meets the preset condition.

[0076] In some embodiments, when the preset condition is met, it is confirmed that the collimation accuracy of the magnet 100 meets the preset condition.

[0077] In some embodiments, the coordinate measuring machine 20 is further configured to measure the coordinate values of any set of points in the Hall point measurement platform coordinate system A3 to obtain a fourth set of coordinate values P4; the laser tracker is further configured to measure the coordinate values of any set of points in the laser tracker coordinate system A2 to obtain a fifth set of coordinate values P5; the calculation module is further configured to use the fourth set of coordinate values P4 as the control network points of the laser tracker, and based on the fourth set of coordinate values P4 and the fifth set of coordinate values P5, adjust the laser tracker coordinate system A2 to make the laser tracker coordinate system A2 coincide with the Hall point measurement platform coordinate system A3.

[0078] In some embodiments, any set of points is the target of the collimator magnet 100.

[0079] In some embodiments, the coordinate measuring machine 20 is further configured to establish a mechanical coordinate system A1 of the collimator magnet, and / or establish a Hall point measurement platform coordinate system A3 according to the movement track of the Hall point measurement platform 10.
