Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0051] As described in the background section, various factors such as raw materials, human factors, equipment, processes, and environment can negatively impact the magnetization of permanent magnets, making it difficult to ensure the consistency and uniformity of the magnetic flux. To address this, the inventors of this application have designed a novel magnetization detection device that solves the problem of inconsistent magnetic flux in magnetized permanent magnets in the prior art. The magnetization detection device of this application will be described in detail below with reference to the accompanying drawings.

[0052] It should be noted that "first direction" in this application is an appendix. Figure 1 The direction indicated by the letter X in the middle, "second direction" is attached. Figure 1 The direction indicated by the letter Y in this application refers to the "sample" which includes a magnet.

[0053] See Figures 1 to 4 As shown, this application provides a magnetization detection device, which includes a magnetization stage (not shown in the figure), a magnetization coil 20, a support mechanism 30, a pressing mechanism 40, a detection mechanism 50, and a transfer mechanism 60.

[0054] The magnetization platform is equipped with a magnetization station 101 and a testing station 102 (see attached). Figure 1(with plane A as the boundary); a magnetizing coil 20 is disposed at the magnetizing station 101, and the magnetizing coil 20 is used at least to magnetize the sample to be magnetized; a support mechanism 30 is disposed at the magnetizing station 101 and located below the magnetizing coil 20, and the support mechanism 30 is used at least to limit and fix the sample and move the sample into the magnetizing coil 20; a pressing mechanism 40 is disposed at the magnetizing station 101 and located above the magnetizing coil 20, and the pressing mechanism 40 is used at least to cooperate with the support mechanism 30 to fix the sample; a detection mechanism 50 is disposed at the detection station 102, and the detection mechanism 50 includes a detection line. The system includes a detection coil 51, a fluxmeter 52, and a rotating placement assembly 53. The detection coil 51 is electrically connected to the fluxmeter 52. The detection coil 51 is used at least to sense the change in magnetic flux of the magnetized sample. The fluxmeter 52 is used at least to detect the magnitude of the magnetic flux of the magnetized sample. The rotating placement assembly 53 is at least partially located within the detection coil 51 and is used at least to limit and fix the magnetized sample and drive the sample to rotate. A transfer mechanism 60 is movably disposed on the magnetization stage and is used at least to move the sample to the magnetization station 101 or the detection station 102.

[0055] In this embodiment, when using the magnetization detection device, the sample to be magnetized can be placed on the support mechanism 30 manually or mechanically. Then, the pressing mechanism 40 is lowered to the position of the sample and comes into contact with it. At this time, the support mechanism 30 and the pressing mechanism 40 cooperate to limit and fix the sample to be magnetized. Then, the support mechanism 30 and the pressing mechanism 40 move downward synchronously to place the sample to be magnetized in the magnetization coil 20, and the magnetization coil 20 is used to saturate magnetize the sample to make it magnetic. After magnetization is completed, the pressing mechanism 40 and the support mechanism 30 move upward and move to their respective initial positions. Then, the transfer mechanism 60 moves the magnetized sample from the support mechanism 30 to the rotating placement assembly 53. Then, the rotating placement assembly 53 drives the sample to rotate in the detection coil 51. The detection coil 51 can sense the change in magnetic flux of the magnetized sample, and the magnetometer 52 can detect the magnitude of the magnetic flux detected by the detection coil 51.

[0056] In this way, when the magnetic flux value of the sample is within the preset range, the sample can be moved from the rotating placement component 53 to the support mechanism 30 by the transfer mechanism 60, and then the sample can be removed manually or mechanically. When the magnetic flux value of the sample is outside the preset range, the sample can be moved from the rotating placement component 53 to the support mechanism 30 by the transfer mechanism 60, and then the above magnetization operation can be repeated to place the sample in the magnetization coil 20. Then, the magnetization coil 20 can be magnetized or demagnetized according to the detection value of the magnetometer 52. Then, the sample can be moved from the support mechanism 30 to the rotating placement component 53 by the transfer mechanism 60 to detect the magnetic flux in the detection coil 51. If the magnetic flux value of the sample is still outside the preset range, the above operation is repeated until the magnetic flux value is within the preset range. Therefore, the magnetization detection device in this embodiment can keep the magnetic flux of the magnetized sample consistent, thereby achieving magnetic stabilization of the sample and keeping its performance stable. At the same time, the entire magnetization detection process does not require manual intervention, which greatly reduces the difficulty of operation for workers, saves labor, and effectively improves production efficiency.

[0057] In other words, the magnetization detection device in this embodiment integrates the magnetization process and the detection process, which can not only ensure the consistency and uniformity of the magnetic flux of the sample to ensure that the sample meets the standard, but also reduce manual operation, reduce the difficulty of manual operation, and effectively improve production efficiency.

[0058] It should be noted that the "preset range of magnetic flux" in this application refers to the magnetic flux Φ satisfying the relationship: 101.718μsμ-0.25%≤Φ≤101.718μVsμ10.25%, such as 101.7155μVsμ, 101.7160μVsμ, 101.7165μVsμ, 101.7170μVsμ, 101.7175μVsμ, 101.7180μVsμ, 101.7185μVsμ, 101.7190μVsμ, 101.7195μVsμ, 101.200μVsμ, 101.7205μVsμ and any value between them.

[0059] Further, see Figure 1As shown, the support mechanism 30 in this embodiment includes a first column 31, a first drive cylinder 32, a first connecting part 33, a support part 34, and a first limiting part 35. The first column 31 is disposed on the magnetization platform and located at the magnetization station 101. A first guide rail 311 is disposed on the first column 31, extending along a first direction. The first drive cylinder 32 is disposed on the first column 31. The first connecting part 33 is movably disposed on the first column 31 and is drivenly connected to the first drive cylinder 32, so that it reciprocates on the first guide rail 311 under the drive of the first drive cylinder 32. The support part 34 is disposed on the side of the first connecting part 33 away from the first drive cylinder 32. The first limiting part 35 is disposed at the end of the support part 34 away from the first connecting part 33. In other words, in this embodiment, the sample to be magnetized can be placed on the first limiting part 35 manually or mechanically. Then, the pressing mechanism 40 is lowered to the position of the sample and comes into contact with it. At this time, the first limiting part 35 and the pressing mechanism 40 cooperate to limit and fix the sample to be magnetized. Then, the first connecting part 33 is driven to move downward along the first guide rail 311 by the first driving cylinder 32, thereby driving the support part 34 and the first limiting part 35 to move downward synchronously, so that the sample to be magnetized can be located inside the magnetization coil 20, and finally the sample is magnetized. It can be seen that the support mechanism 30 in this embodiment can achieve precise positioning and fixation of the sample, as well as rapid and accurate movement on the magnetization station 101, which improves the efficiency and accuracy of the magnetization process to a certain extent and avoids the influence caused by human operation.

[0060] Specifically, in this embodiment, the first column 31 provides support for the entire support mechanism 30, ensuring its stable operation; the first guide rail 311 provides a stable moving path for the first connecting part 33; the first drive cylinder 32 provides power to drive the other components of the support mechanism 30 to move; the first connecting part 33 provides support for the support part 34 and the first limiting part 35, and transmits the driving force of the first drive cylinder 32 to the support part 34 and the first limiting part 35; the support part 34 provides support for the first limiting part 35; the first limiting part 35 is used to limit and fix the sample, preventing the sample from falling off during the operation of the support mechanism 30, effectively ensuring the normal operation of the support mechanism 30.

[0061] Further, see Figure 1 as well as Figure 3As shown, in this embodiment, the first connecting part 33 includes a first connecting plate 331, the supporting part 34 includes a supporting column 341, and the first limiting part 35 includes a first limiting block 351. The first limiting block 351 has a first limiting groove 3511 and a first clearance groove 3512. The first limiting groove 3511 and the first clearance groove 3512 are connected, and their extending directions are different. Specifically, the first limiting groove 3511 facilitates the installation and fixation of the sample; the first clearance groove 3512 facilitates the transfer mechanism 60 to clamp the sample to separate it from the first limiting block 351. In this embodiment, the sample and the first limiting groove 3511 can be connected by snap-fit, screw connection, or other methods.

[0062] Further, see Figure 1 As shown, the pressing mechanism 40 in this embodiment includes a second column 41, a second driving cylinder 42, and a pressing rod assembly 43. The second column 41 is disposed at the magnetization station 101, and a second guide rail 411 is provided on the second column 41, extending along a first direction. The second driving cylinder 42 is disposed on the second column 41. The pressing rod assembly 43 is disposed on the second column 41 and is drivenly connected to the second driving cylinder 42, so that it reciprocates on the second guide rail 411 under the drive of the second driving cylinder 42. That is, in this embodiment, when the sample is placed on the support mechanism 30, the pressing rod assembly 43 can be driven by the second driving cylinder 42 to descend to the position of the sample and abut against the sample, thereby allowing the pressing rod assembly 43 to cooperate with the support mechanism 30 to achieve the limiting and fixing of the sample to be magnetized.

[0063] Specifically, in this embodiment, the second column 41 can support the entire pressing mechanism 40 and ensure the stable operation of the pressing mechanism 40; the second guide rail 411 can provide a stable moving path for the pressure rod assembly 43; the second drive cylinder 42 is responsible for providing power to drive the pressure rod assembly 43 to move; the pressure rod assembly 43 can apply a pushing force to the sample to fix the sample on the first limiting part 35.

[0064] Further, see Figure 1As shown, the pressure rod assembly 43 in this embodiment includes a second connecting plate 431, a pressure rod body 432, and a stop block 433. The second connecting plate 431 is mounted on the second column 41 and is drivenly connected to the second driving cylinder 42. The pressure rod body 432 is located at the end of the second connecting plate 431 away from the second driving cylinder 42. The stop block 433 is located at the end of the pressure rod body 432 away from the second connecting plate 431. That is, the second connecting plate 431 reciprocates along the second guide rail 411 under the drive of the second driving cylinder 42, thereby causing the pressure rod body 432 and the stop block 433 to move towards or away from the first limiting part 35. Specifically, the second connecting plate 431 provides support for the pressure rod body 432 and transmits the driving force of the second driving cylinder 42 to the pressure rod body 432; the pressure rod body 432 can be used to apply pressure to the sample; and the stop block 433 is used to directly contact and press the sample.

[0065] Further, see Figure 1 As shown, the magnetizing coil 20 in this embodiment has a first clearance space 201 to allow the support mechanism 30 to reciprocate along a first direction, and a magnetizing position 202 is provided within the first clearance space 201. Specifically, the first clearance space 201 provides sufficient space for the support mechanism 30 to reciprocate along the first direction, allowing the support mechanism 30 to move smoothly within the magnetizing coil 20 without colliding with it, thus preventing damage to the support mechanism 30 and the magnetizing coil 20. At the same time, since the movement of the support mechanism 30 does not interfere with the magnetizing coil 20, the stability and consistency of the magnetic field within the magnetizing coil 20 can be maintained, effectively ensuring the magnetization quality of the sample. The magnetizing position 202 ensures that the sample can be accurately magnetized at the appropriate position.

[0066] Further, see Figure 1 As shown, the rotating placement assembly 53 in this embodiment includes a first drive motor 531, a rotating column 532, and a second limiting part 533. The first drive motor 531 is located at the detection station 102; the rotating column 532 is driven by the first drive motor 531 to rotate under its drive, and the rotating column 532 is at least partially located within the detection coil 51; the second limiting part 533 is located at the end of the rotating column 532 away from the first drive motor 531 and within the detection coil 51. That is, after the sample is magnetized, the transfer mechanism 60 picks up the sample and moves it from the first limiting part 35 to the second limiting part 533. Then, the first drive motor 531 is activated, driving the rotating column 532 to rotate, thereby rotating the second limiting part 533, and consequently causing the sample to rotate within the detection coil 51, thus detecting the magnitude of the sample's magnetic flux.

[0067] Specifically, the first drive motor 531 is responsible for providing rotational power to drive the rotating column 532 to rotate; the rotating column 532 provides support for the second limiting part 533 and transmits the driving force of the first drive motor 531 to the second limiting part 533; the second limiting part 533 is used to limit and fix the sample after magnetization to prevent the sample from falling off during rotation, effectively ensuring the normal operation of the detection mechanism 50.

[0068] Further, see Figure 4 As shown, the second limiting part 533 in this embodiment includes a second limiting block 5331. The second limiting block 5331 has a second limiting groove 5332 and a second clearance groove 5333. The second limiting groove 5332 and the second clearance groove 5333 communicate with each other, and the extension directions of the second limiting groove 5332 and the second clearance groove 5333 are different. Specifically, the second limiting groove 5332 facilitates the installation and fixation of the sample; the second clearance groove 5333 facilitates the transfer mechanism 60 to clamp the sample to separate the sample from the second limiting block 5331. In this embodiment, the sample and the second limiting groove 5332 can be connected by snap-fit, screw connection, or other methods.

[0069] Further, see Figure 1 As shown, in this embodiment, a mounting plate 70 is provided on the magnetizing platform. A lead screw (not shown in the figure), a slider (not shown in the figure), and a second drive motor (not shown in the figure) are provided on the mounting plate 70. The lead screw extends along a second direction, and the slider is movably mounted on the lead screw. The second drive motor is driven and connected to the lead screw to drive the lead screw to rotate, thereby driving the slider to reciprocate along the second direction. The transfer mechanism 60 includes a transfer manipulator 61, which is mounted on the slider. A third drive motor is provided on the transfer manipulator 61 and is driven and connected to the transfer manipulator 61 to drive the transfer manipulator 61 to reciprocate along a first direction.

[0070] Specifically, the combination of the lead screw and slider in this embodiment provides a precise motion control mechanism. When the second drive motor drives the lead screw to rotate, it can accurately control the movement of the slider, thereby driving the transfer robot 61 to reciprocate along the second direction. This, in turn, moves the sample between the magnetization station 101 and the detection station 102 on the magnetization stage, reducing the sample transfer time to a certain extent and effectively improving the production efficiency of the magnetization detection device. When the transfer robot 61 moves the sample from the magnetization station 101 to the detection station 102, the third drive motor can drive the transfer robot 61 to move along the first direction, thereby placing the sample on the second limiting part 533, and thus detecting the magnetic flux of the sample.

[0071] Further, see Figure 1 As shown, the detection coil 51 in this embodiment has a second clearance space 501 to avoid the movement of the transfer mechanism 60 along the first direction, and a detection position is provided within the second clearance space 501. Specifically, the second clearance space 501 provides sufficient movement space for the transfer robot 61 to reciprocate along the first direction, allowing the transfer robot 61 to move smoothly within the detection coil 51 without colliding with it, thereby preventing damage to the transfer robot 61 and the detection coil 51. At the same time, since the movement of the transfer robot 61 does not interfere with the detection coil 51, the stability and consistency of the detection coil 51 during detection can be guaranteed, effectively ensuring the detection of the magnetic flux of the sample; and the setting of the detection position can ensure that the sample can be accurately detected at an appropriate position.

[0072] Specifically, the working principle of the magnetization detection device of this application is as follows:

[0073] First, the sample to be magnetized is placed in the first limiting groove 3511 of the first limiting block 351 by manual or mechanical feeding. Then, the second driving cylinder 42 is activated to drive the pressure rod assembly 43 to move downward in the first direction until the abutment block 433 in the pressure rod assembly 43 abuts against the sample, thus fixing the sample. Then, the first driving cylinder 32 and the second driving cylinder 42 are activated simultaneously to drive the pressing mechanism 40 and the support mechanism 30 to move downward synchronously, thereby moving the sample to the magnetization position 202 in the magnetization coil 20. The first driving cylinder 32 drives the first connecting part 33 to move downward on the first guide rail 311, thereby driving the support part 34 and the first limiting part 35 to move downward. The second driving cylinder 42 drives the second connecting plate 431 to move downward on the second guide rail 411, thereby driving the pressure rod body 432 and the abutment block 433 to move downward synchronously.

[0074] Next, the magnetizing coil 20 is turned on to saturate the sample with a predetermined voltage, thereby making the sample magnetic.

[0075] After the sample is magnetized, the second drive cylinder 42 is activated to drive the pressure rod assembly 43 to move upward in the first direction to its initial position. Simultaneously, the first drive cylinder 32 is activated to drive the first connecting part 33 to move upward in the first direction to its initial position. Then, the second drive motor is activated, driving the transfer robot 61 to move upward in the second direction above the first limiting block 351. Next, the third drive motor is activated, driving the transfer robot 61 downward in the first direction to the first limiting block 351, where it grips the magnetized sample. After the sample is gripped, the third drive motor is activated, driving the transfer robot 61 upward in the first direction. Then, the second drive motor is activated, driving the transfer robot 61 to move upward in the second direction to above the second limiting block 5331. Finally, the third drive motor drives the transfer robot 61 downward in the first direction to the second limiting block 5331, placing the sample in the second limiting groove 5332.

[0076] After the sample is installed, the magnetometer 52 is zeroed first, and then the detection coil 51 and the first drive motor 531 are turned on at the same time. The first drive motor 531 drives the rotating column 532 to rotate, thereby driving the second limit block 5331 to rotate synchronously, and then driving the sample to rotate in the detection coil 51 to complete the detection of magnetic flux.

[0077] The magnetic flux of the sample is detected by the fluxmeter 52. When the magnetic flux of the sample is within the preset range, the sample can be moved from the detection station 102 to the magnetization station 101 by the transfer mechanism 60, and then the sample can be removed manually or mechanically. When the magnetic flux of the sample is outside the preset range, the sample can be moved from the detection station 102 to the magnetization station 101 by the transfer mechanism 60, and the sample can be magnetized or demagnetized by the magnetization coil 20. Then the sample can be moved from the magnetization station 101 to the detection station 102 again to re-detect the magnetic flux of the sample. If the magnetic flux of the sample is still outside the preset range, the above actions are repeated until the magnetic flux of the sample is within the preset range.

[0078] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0079] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0080] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
