[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation manner of the present application will be clearly and completely described below in conjunction with the drawings in the implementation manner of the present application.

[0022] like Figure 1 As shown, the embodiment of the present application provides a magnetic susceptibility detection device 100, which is specifically used to detect the magnetic susceptibility of a material, that is, the ratio of the magnetization intensity to the magnetic field intensity. Effective detection and rating of the magnetic susceptibility of a material is one of the important indicators for evaluating the quality of a material, which can effectively avoid the production of inferior quality products and is of great significance to maintaining product stability.

[0023] like Figure 1 and Figure 2 As shown, the magnetic susceptibility detection device 100 includes a detector body 10 , a material holding member 20 , a magnetic member 30 and a moving assembly 40 .

[0024] The detector body 10 constitutes the main frame of the detection device 100, and the detector body 10 is provided with a detection position 101 for placing the material holding piece 20 (see Figure 4 ), wherein the detection position 101 can be a groove that is substantially consistent with the outer contour of the material holding piece 20 to facilitate positioning of the material holding piece 20.

[0025] It should be noted that the present application does not specifically limit the structure of the detection position 101 , and the detection position 101 can be adjusted accordingly to adapt to the specific shape of the material container 20 .

[0026] The material holding piece 20 is used to hold materials, wherein the material holding piece 20 filled with materials can achieve effective sealing, thereby preventing material leakage during the detection process from causing deviations in the detection results.

[0027] In the example of this application, the material is nickel-plated micropowder, which is one of the three major raw materials for diamond wire. The cutting ability of diamond wire is strongly positively correlated with the density of diamond particles on the diamond wire. It can also be said that the density of diamond particles determines the cutting ability of diamond wire to a certain extent. The sanding ability of nickel-plated micropowder determines the density of diamond particles, and the magnetic strength of nickel-plated micropowder is one of the important indicators of the sanding ability of micropowder.

[0028] like Figure 2 As shown, the magnetic member 30 is mounted on the moving assembly 40, and the magnetic member 30 can move synchronously with the moving assembly 40. Specifically, the magnetic member 30 is arranged outside the detection position 101, and can apply magnetic attraction to the material in the material holding member 20.

[0029] The moving assembly 40 is mounted on the detector body 10 , and at least a portion of the moving assembly 40 has the freedom of movement to move vertically relative to the detector body 10 . The moving assembly 40 acts on the magnetic member 30 to drive the magnetic member 30 to approach or move away from the material receiving member 20 .

[0030] like Figure 2 As shown, the detection device 100 provided in the embodiment of the present application also includes a detection component 50, which is installed on the detector body 10, and at least a part of the detection component 50 faces the detection position 101. The detection component 50 is specifically used to detect whether the material container 20 is out of the detection position 101.

[0031] like Figure 3 As shown, the detection assembly 50 has a detection part 501, and the detection part 501 is electrically connected or communicatively connected with the moving assembly. The detection part 501 has a first state and a second state. When the material receiving part 20 is located at the detection position 101, the detection part 501 is in the first state, and the moving assembly 40 can drive the magnetic part 30 to move toward the direction close to the material receiving part 20.

[0032] When the material holding member 20 is separated from the detection position 101, the detection unit 501 is in the second state and generates an electrical signal, for example, an inhibition signal, and transmits the electrical signal to the moving component 40, and the moving component 40 stops moving in response to the electrical signal. At this time, the position of the magnetic member 30 is the critical position. It can be understood that the critical position is the position of the magnetic member 30 when the detection unit 501 switches from the first state to the second state.

[0033] It should be noted that the magnetic member 30 also includes an initial position, which is a position where the magnetic member 30 and the detection position 101 have a maximum height difference in the vertical direction.

[0034] During the process of detecting the magnetic susceptibility of the material, a certain amount of material is placed in the material holding member 20. When the moving component 40 drives the magnetic member 30 to move downward from the initial position to the critical position, the material holding member 20 is separated from the detection position 101 due to the attraction between the material and the magnetic member 30. At this time, the moving component 40 stops moving and records the height of the critical position.

[0035] like Figure 1 As shown, as an implementation method, the detection device 100 also includes a display module 60, which is fixedly mounted on the detector body 10. The display module 60 can be a liquid crystal display, a digital display, etc. The height of the critical position of the magnetic part 30 can be presented through the display module 60 to enhance the visualization of the detection results.

[0036] Specifically, the display module 60 is electrically connected to the moving component 40. When the moving component 40 stops at the critical position, the moving component 40 generates a distance signal and transmits it to the display module 60. The display module 60 parses the distance signal and presents it on its display interface. The display module 60 displays the height difference between the initial position and the critical position.

[0037] Exemplarily, when the magnetic member 30 is at the initial position, the display module 60 displays that the magnetic member 30 is at a first height H1, and the first height H1 is the height difference between the initial position and the detection position 101 in the vertical direction, wherein the detection position 101 is taken as the zero point. When the moving assembly 40 drives the magnetic member 30 to move downward until the material receiving member 20 is separated from the detection position 101, the display module 60 displays that the magnetic member 30 is at a second height H2, and the second height H2 is the height difference between the critical position and the detection position 101 in the vertical direction.

[0038] In the example of the present application, the display module 60 includes at least a first display area 601 and a second display area 602, the first display area 601 is used to display the height difference between the initial position and the critical position in the vertical direction, and the second display area 602 is used to display the magnetic susceptibility of the material represented by the height difference.

[0039] When the height difference is within the set range, it means that the magnetic susceptibility of the batch of materials to be tested is good.

[0040] In other examples, the first display area 601 is used to display the height difference between the critical position and the detection position 101 in the vertical direction, and the second display area 602 is used to display the magnetic susceptibility of the material represented by the height difference.

[0041] Through the above settings, by expressing the magnetic susceptibility of the material in the form of height difference, the visualization of the detection results is improved, so that operators can more easily understand the indicators of the magnetic strength of the material.

[0042] like Figure 2 As shown, as an implementation method, the moving component 40 includes an electric cylinder 401 and a slider 402, the electric cylinder 401 is installed on the detector body 10, the slider 402 is connected to the electric cylinder 401, and the slider 402 is driven by the electric cylinder 401 to move in the vertical direction, wherein the magnetic component 30 is fixedly installed on the slider 402.

[0043] Specifically, the electric cylinder is a modular product that integrates a servo motor and a lead screw. It converts the rotational motion of the servo motor into linear motion, and at the same time converts the best advantages of the servo motor such as precise speed control, precise rotation speed control, and precise torque control into precise speed control, precise position control, and precise thrust control.

[0044] In other examples, the moving assembly 40 includes a guide rail, a slider, and a driving member for driving the slider to move. The guide rail extends in the vertical direction and is fixedly mounted on the detector body 10, the slider is slidably connected to the guide rail, and the driving assembly is transmission-connected to the slider. The driving member can be a servo motor and a rack matched with the servo motor, the rack is connected to the slider, and the slider moves relative to the guide rail in the vertical direction through the mutual cooperation of the servo motor and the rack.

[0045] like Figure 3 As shown, as an implementation, the detection part 501 is an amplifier, and the detection component 50 also includes an optical fiber 502 connected to the amplifier 501, at least part of the optical fiber 502 extends in the direction of the detection position 101, and one end of the optical fiber 502 faces the detection position 101, and is used to sample the light at the detection position 101. The other end of the optical fiber 502 is connected to the amplifier 501, and the amplifier 501 converts the optical signal sampled by the optical fiber 502 into an electrical signal and transmits it to the moving component 40, so as to control the moving component 40 to stop when moving close to the material holding part 20.

[0046] In other examples, the amplifier 501 is electrically connected to the mobile component 40 through a driving circuit. The driving circuit can be a main control circuit of the detection device 100 or a control circuit set by the detection device 100 for the mobile component 40. The function of the driving circuit is mainly to receive, convert, and forward signals. There is no specific limitation on the installation form of the driving circuit. The driving circuits that meet the above functions are within the scope mentioned in this application.

[0047] like Figure 4 As shown, the detection component 50 also includes an optical fiber fixing plate 503 and an optical fiber cover plate 504 stacked up and down. The optical fiber fixing plate 503 is provided with a channel 505 for accommodating the optical fiber 502. The optical fiber cover plate 504 is covered on the optical fiber fixing plate 503 to cover the channel 505 in the vertical direction to prevent external light from affecting the amplifier 501.

[0048] When the material holding member 20 is placed at the detection position 101, the material holding member 20 blocks the optical fiber 502. When the moving assembly 40 drives the magnetic member 30 to move downward to the critical position, the material holding member 20 containing the material is sucked up by the magnetic member and separated from the detection position 101. At this time, the optical fiber 502 receives the light and transmits the light to the amplifier 501, so that the amplifier 501 generates an electrical signal to control the moving assembly 40.

[0049] Optionally, the detection unit 501 is an amplifier, and the detection component 50 further includes a gravity sensor connected to the amplifier 501, and the gravity sensor is disposed below the detection position 101, and the gravity change obtained by the gravity sensor is used to generate an electrical signal for controlling the moving component 40. Accordingly, the detection component 50 may also include a signal amplifier 501 that cooperates with the gravity sensor, which will not be described in detail here.

[0050] In addition, the detection component 50 may also include any sensor device such as a displacement sensor that can detect the position change of the material holding member 20 , and the sensor device is connected to the detection part 501 .

[0051] As an implementation method, the detection device 100 also includes a reset button (not shown), which is electrically connected to the moving component 40. The touch operation of the reset button can generate a reset signal, and the moving component 40 calibrates the initial position of the magnetic component 30 in the vertical direction in response to the reset signal.

[0052] It is understandable that if the initial position of the magnetic member 30 is too high, the height difference between the initial position and the critical position may be too large, resulting in a decrease in the magnetic susceptibility of the material in the actual detection result. If the initial position of the magnetic member 30 is too low, the height difference between the initial position and the critical position may be too small, resulting in an increase in the magnetic susceptibility of the material in the actual detection result.

[0053] The above problems may lead to deviations in the final detection results. Therefore, a reset button is provided to calibrate the initial position of the magnetic member 30 after a certain number of detections.

[0054] Although the present application provides a reset button, in actual applications, the reset button can also be integrated into the display module 60 , and the above-mentioned calibration action is performed by a touch operation on the display module 60 .

[0055] In the example of the present application, the material holding member 20 is in the shape of a capsule, and the capsule-shaped material holding member 20 includes a detachable first part and a second part, and a mark is provided on either the first part or the second part, wherein the mark can be a color mark, a graphic mark, etc., which is not specifically limited here.

[0056] Before testing the material, open the material container 20, pick up a certain amount of material and put it into the marked part of the material container 20, install the first part and the second part to form a closed space. Further, place the material container 20 at the detection position 101, and the marked end of the material container 20 faces the operator. Start the moving component 40 and start to detect the magnetic susceptibility of the material in the material container 20. The magnetic component 30 slowly descends under the drive of the moving component 40 until the magnetic component 30 absorbs the material container 20. After the material container 20 is sucked up, the optical fiber 502 senses the light and transmits the light to the amplifier 501. The amplifier 501 converts the optical signal into an electrical signal and transmits the electrical signal to the moving component 40. The moving component 40 stops moving in response to the electrical signal. At this time, the display module 60 displays the height difference between the initial position and the critical position of the magnetic component 30, and uses the height difference as an indicator of the magnetic susceptibility of the material.

[0057] In summary, through the linkage between the detection component 50 and the moving component 40, the difference between the critical position and the initial position is used as the evaluation index of the magnetic susceptibility of the material, the operation is more convenient, and the visualization degree of the detection result is higher.

[0058] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
