Furthermore, the terms "first," "second," etc., are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data used can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0036] This application provides a magnetic force testing system; please refer to [reference needed]. Figure 1-4 The device includes: a magnetic component, a magnetic test component 1, a position fixing component 2, a positioning component, and a controller; the position fixing component 2 is fixedly connected to the magnetic test component 1; the magnetic test component 1 is provided with multiple magnetic component receiving slots 11, and the magnetic component is disposed in the magnetic component receiving slots 11; the positioning component is used to fix the test component; the magnetic component has the opposite polarity to the magnetic device in the test component; the controller is used to control the magnetic test component 1 to move to magnetic connection with the test component on the positioning component during the magnetic force test of the test component, and in response to the magnetic connection between the magnetic test component 1 and the test component, control the magnetic test component 1 to move away from the test component until the distance between the magnetic test component and the test component is greater than or equal to a preset distance, and acquire the magnetic force test result of the test component during the movement of the magnetic test component 1.

[0037] This application uses the magnetic force generated by a magnetic test piece as a magnetic standard, and uses the magnetic test piece to replace the actual part to perform magnetic force testing on the part under test. During the magnetic force testing process, the magnetic test piece is controlled to move until it magnetically connects with the part under test on the positioning part. In response to the magnetic connection between the magnetic test piece and the part under test, the magnetic test piece is controlled to move away from the part under test until the distance between the magnetic test piece and the part under test is greater than or equal to a preset distance. The magnetic force test results of the part under test are obtained during the movement of the magnetic test piece. The entire testing process is simple to operate, improves the detection efficiency and stability of magnetic force testing, as well as the installation stability of each part.

[0038] The magnetic test piece of this application replaces the real part for magnetic force testing of the part to be tested. Since the size and structure of the real part cannot be arbitrarily changed, while the size and structure of the magnetic test piece of this application can be set to be smaller and more compatible with the part to be tested, thereby increasing the testing space area and leaving space for the positioning part to fix the part to be tested, thus improving the fixation stability of the part to be tested.

[0039] In some embodiments, the magnetic component includes, but is not limited to, a magnet, and may also be other objects with magnetic properties. The magnetic component may be a cuboid, a cube, or a sphere, and its size is not limited herein, as long as it can be disposed within the magnetic component receiving groove 11;

[0040] In some embodiments, the number of magnetic elements can correspond one-to-one with the magnetic element receiving slots 11; in other embodiments, one or more magnetic elements can be provided in a single magnetic element receiving slot 11; in other embodiments, no magnetic elements may be provided in a single magnetic element receiving slot 11; the number of magnetic elements and the position of the magnetic elements in multiple magnetic element receiving slots 11 are not limited here, and can be designed according to the magnetic position of the item to be tested.

[0041] In some embodiments, the number of magnetic elements is proportional to the magnetic force generated by the magnetic test piece; that is, the more magnetic elements there are, the greater the magnetic force generated by the magnetic test piece.

[0042] In some embodiments, the size of the magnetic component receiving groove 11 is not limited, as long as the space inside the groove is large enough to accommodate the magnetic component.

[0043] In one specific embodiment, the length of the magnetic component receiving groove 11 can be 3.03 mm.

[0044] In one specific embodiment, the width of the magnetic component receiving groove 11 can be 1.05 mm.

[0045] In some embodiments, the length tolerance and width tolerance of the magnetic component receiving groove 11 are less than or equal to ±0.02 mm.

[0046] This application ensures the machining accuracy of the magnetic test piece by controlling the machining length and machining width of the magnetic component receiving groove 11, so that the magnetic test piece forms the target magnetic force, and uses the magnetic force of the magnetic test piece as the standard for detecting magnetic force.

[0047] In some embodiments, the wall thickness tolerance of the magnetic component receiving groove 11 is less than or equal to ±0.01 mm.

[0048] In some embodiments, the positional tolerance of the magnetic component receiving groove 11 is less than or equal to ±0.05 mm.

[0049] This application further controls the positional accuracy and wall thickness of the magnetic component receiving groove 11 to ensure the processing accuracy of the magnetic force test piece, so that the magnetic force test piece forms the target magnetic force, and uses the magnetic force of the magnetic force test piece as the standard for detecting magnetic force.

[0050] In some embodiments, the magnetic component receiving groove 11 is snapped into the magnetic component, and the outer periphery of the magnetic component abuts against the magnetic component receiving groove 11. Without the use of force, the magnetic component cannot be detached from the magnetic component receiving groove 11.

[0051] In other embodiments, the magnetic component receiving groove 11 is bonded to the magnetic component, allowing the magnetic component to move within the magnetic component receiving groove 11. The magnetic component is fixed within the magnetic component receiving groove 11 by applying adhesive. Specifically, 502 adhesive can be used.

[0052] In some embodiments, the positioning element and the test element are applied one-to-one to fix the test element. Different test elements are matched with the same or different positioning elements. By using different positioning elements, the fixation compatibility between the positioning element and the test element is improved, and the fixation stability of the test element is improved.

[0053] In some embodiments, the positioning element includes a first positioning element and a second positioning element. The first positioning element and the second positioning element may be the same, and the test piece includes a detection end and a fixed end. The first positioning element is used to fix the detection end of the test piece to ensure that the test piece will not be displaced during the testing process. The second positioning element is used to fix the fixed end of the test piece. The double-end fixing enhances the stability of the test piece in the magnetic test.

[0054] In some embodiments, the positioning element includes a positioning block and a positioning plate. The positioning block is used to fix the object to be tested in the horizontal direction, and the positioning plate is used to fix the object to be tested in the azimuth direction.

[0055] In one specific embodiment, the test piece is placed at a preset position on the positioning plate and fixed to the positioning plate. The fixing method is not limited here and can be adhesive. Then, the positioning block is fixedly contacted with the test end of the test piece to ensure that during the magnetic force test, after the test piece is magnetically connected to the magnetic force test piece 1, the test piece remains stable on the positioning plate under the magnetic force action of the magnetic force test piece 1 moving away from the test piece.

[0056] In some embodiments, the position fixing member 2 is disposed on the outer periphery of the magnetic force test member 1, and the magnetic force test member 1 has a hollow structure.

[0057] This application uses a positioning fixing member 2 set on the outer periphery of the magnetic force test piece 1. When the magnetic force test piece 1 moves away from the test piece to perform magnetic force testing, the magnetic force test piece 1 is relatively located inside the whole structure, which improves the testing stability of the magnetic force test piece 1. The magnetic force test piece 1 has a hollow structure, which saves space and cost.

[0058] In some embodiments, the magnetic test piece 1 includes a detection surface 12; the detection surface 12 is used to magnetically connect with the contact surface of the test piece, and the profile of the detection surface 12 matches the profile of the contact surface of the test piece.

[0059] The detection surface 12 of this application is machined using five-axis high-precision curved surface. By controlling the various dimensions of the detection surface 12, the uniformity of the magnetic test piece 1 is ensured. By matching the contour of the detection surface 12 with the contour of the contact surface of the test piece, the magnetic contact fit between the test piece and the magnetic test piece 1 is improved, thereby improving the magnetic detection effect of the test piece.

[0060] In some embodiments, the profile tolerance of the detection surface 12 is less than or equal to ±0.05 mm.

[0061] This application ensures the machining accuracy of the magnetic test piece by controlling the contour of the test surface 12, so that the magnetic test piece forms the target magnetic force, and uses the magnetic force of the magnetic test piece as the standard for detecting magnetic force.

[0062] In some embodiments, the detection surface 12 is further provided with a magnetic observation hole 14, which is connected to the magnetic receiving groove 11.

[0063] This application provides a magnetic component observation hole 14, which facilitates observation of the installation position of the magnetic component in the magnetic component receiving groove 11, reduces the installation difficulty of the magnetic component, and effectively ensures that the magnetic component is installed in the target position in the magnetic component receiving groove 11.

[0064] In some embodiments, the magnetic observation hole 14 corresponds one-to-one with the magnetic receiving groove 11, that is, a magnetic observation hole 14 is provided on the detection surface 12 corresponding to each magnetic receiving groove 11.

[0065] In other embodiments, each magnetic component receiving groove 11 has a plurality of magnetic component observation holes 14 on its detection surface 12. For example, each magnetic component receiving groove 11 has two magnetic component observation holes 14 on its detection surface 12. Please refer to [reference needed]. Figure 2 , Figure 2 The present invention relates to a schematic diagram of a magnetic force testing system in an embodiment of the application.

[0066] In some embodiments, the detection surface 12 of the magnetic test piece 1 protrudes from the position fixing member 2.

[0067] This application sets the detection surface 12 of the magnetic test piece 1 to protrude from the position fixing member 2, while the other opposite surface of the detection surface of the magnetic test piece 1 does not protrude from the position fixing member 2, forming a clear contrast, making it easy to distinguish which side of the magnetic test piece 1 is the detection surface. Furthermore, the detection surface 12 of the magnetic test piece 1 and the position fixing member 2 form a spatial three-dimensional interlacing, preventing the position fixing member 2 from hindering the detection process of the magnetic test piece 1 and improving the overall detection effect of the magnetic test piece 1.

[0068] In some embodiments, the magnetic test piece 1 includes a grooved surface 13; the grooved surface 13 is disposed opposite to the detection surface 12; and a plurality of magnetic element receiving grooves 11 are disposed on the grooved surface 13.

[0069] By providing a grooved surface 13, this application effectively reduces manufacturing costs and minimizes the molding space of the magnetic test piece 1, while ensuring that the grooved surface 13 can accommodate the magnetic component.

[0070] In some embodiments, a tension sensor is also included; the tension sensor is communicatively connected to the controller; the tension sensor is used to collect magnetic force data between the magnetic test piece 1 and the test piece during the movement of the magnetic test piece 1 away from the test piece, and send the magnetic force data to the controller, so that the controller can perform magnetic force detection based on the magnetic force data and the distance between the magnetic test piece 1 and the test piece to obtain the magnetic force test result. It should be noted that the magnetic force test result indicates whether the magnetic force effect generated by the test piece is qualified.

[0071] This application, by setting up a tension sensor, allows for real-time observation of the magnetic force change between the magnetic test piece and the test piece during the magnetic force detection process as the magnetic test piece moves away from the test piece after magnetic connection. This provides a specific magnetic force change value and improves the detection effect of the entire magnetic force detection process.

[0072] In some embodiments, the magnetic force data may include, but is not limited to, a curve showing the change in force value between the magnetic test piece 1 and the test piece. During the magnetic force test when the magnetic test piece 1 is moving away from the test piece, a curve showing the change in force value as the distance between the magnetic test piece 1 and the test piece changes is acquired in real time. Please refer to [reference needed] for details. Figure 4 As shown in the figure, the distance between the magnetic test piece 1 and the test piece gradually increases, while the force between the magnetic test piece 1 and the test piece first increases to the peak value of the magnetic force and then decreases, gradually approaching 0.

[0073] In some embodiments, the position fixing member 2 is provided with a mounting hole 21; the position fixing member 2 is fixed to the tension sensor through the mounting hole 21.

[0074] This application improves the stability of magnetic force testing by providing mounting holes 21 on the position fixing component 2 and fixing the position fixing component 2 to the tension sensor through the mounting holes 21, which means fixing the magnetic force testing component 1 to the tension sensor.

[0075] Specifically, the tension sensor includes a mounting plate with a mounting hole 21 and a fixing hole matching the mounting hole 21. Fasteners are inserted into both the mounting hole 21 and the fixing hole to fix the position fixing member 2 to the mounting plate.

[0076] In some embodiments, a positioning pin is also included. The positioning fastener 2 is provided with a positioning pin hole 22. The positioning pin passes through the positioning pin hole 22 to position the positioning fastener 2 between itself and the tension sensor, that is, to position the magnetic test piece 1 between itself and the tension sensor, thereby determining the fixed position of the positioning fastener 2 and the magnetic test piece 1.

[0077] In some embodiments, during the magnetic force test of the test piece, after the magnetic force test piece 1 is magnetically connected to the test piece, the magnetic force test piece 1 is controlled to move away from the test piece until the distance between the magnetic force test piece and the test piece is greater than or equal to a preset distance, wherein the preset distance can be 5 mm, and the speed at which the magnetic force test piece 1 moves away from the test piece can be less than or equal to 0.65 mm / s.

[0078] In some embodiments, the tension sensor is calibrated by suspending a standard weight below the tension sensor, obtaining the tension sensor value, and determining whether the tension sensor value matches the weight of the standard weight. If the tension sensor value matches the weight of the standard weight, the tension sensor is determined to be normal and can be used to perform magnetic force testing on the workpiece.

[0079] In some embodiments, the magnetic force testing system provided in this application for detecting the magnetic force effect on a test piece includes the following steps:

[0080] S1: Place the part to be tested on the testing platform.

[0081] S2: The position of the part to be tested is fixed by the positioning component.

[0082] S3: Place the magnetic test piece 1 at the interval above the test piece.

[0083] S4: The controller controls the magnetic test piece 1 to move downward from above the test piece until it is magnetically connected to the test piece, and the detection surface of the magnetic test piece 1 is completely in contact with the detection surface of the test piece.

[0084] S5: In response to the magnetic connection between the magnetic test piece 1 and the test piece, the controller controls the magnetic test piece 1 to move away from the test piece until the distance between the test piece and the test piece is greater than or equal to a preset distance.

[0085] As the magnetic test piece 1 moves away from the test piece, the tension sensor collects the magnetic force change data between the magnetic test piece 1 and the test piece in real time and sends the magnetic force change data to the controller.

[0086] S6: The controller performs magnetic force detection based on the magnetic force change data and the distance between the magnetic force test piece 1 and the part under test, and obtains the magnetic force test result. It should be noted that the magnetic force test result indicates whether the magnetic force generated by the part under test is qualified.

[0087] The following are some specific embodiments of the above technical solutions listed in this specification.

[0088] Example 1

[0089] This embodiment 1 discloses a magnetic force testing system, applied in the field of VR glasses technology. Please refer to [link / reference needed]. Figure 1-4 The device includes: a magnetic component, a magnetic test component 1, a position fixing component 2, a positioning component, and a controller; the position fixing component 2 is fixedly connected to the magnetic test component 1; the magnetic test component 1 is provided with multiple magnetic component receiving slots 11, and the magnetic component is disposed in the magnetic component receiving slots 11; the positioning component is used to fix the test component; the magnetic component has the opposite polarity to the magnetic device in the test component; the controller is used to control the magnetic test component 1 to move to magnetic connection with the test component on the positioning component during the magnetic force test of the test component, and in response to the magnetic connection between the magnetic test component 1 and the test component, control the magnetic test component 1 to move away from the test component until the distance between the magnetic test component and the test component is greater than or equal to a preset distance, and acquire the magnetic force test result of the test component during the movement of the magnetic test component 1.

[0090] Specifically, the component to be tested can be the frame of VR glasses, and the corresponding component can be the lens of VR glasses. In the prior art, the magnetic effect of the VR glasses frame is tested by directly allowing the lens of VR glasses to attract the frame of VR glasses. The magnetic test component of this application replaces the component (the lens or frame of VR glasses) to perform magnetic testing on the component to be tested. Since the size and structure of the component cannot be arbitrarily changed, while the size and structure of the magnetic test component of this application can be set to be smaller and more compatible with the component to be tested, the testing space area is increased, and space can be left for the positioning component to fix the component to be tested, thereby improving the fixation stability of the component to be tested.

[0091] Specifically, the magnetic test piece 1 includes a detection surface 12; the detection surface 12 is used to magnetically connect with the contact surface of the test piece, and the profile of the detection surface 12 matches the profile of the contact surface of the test piece.

[0092] The detection surface 12 of this application is machined using five-axis high-precision curved surface. By controlling the various dimensions of the detection surface 12, the uniformity of the magnetic test piece 1 is ensured. By matching the contour of the detection surface 12 with the contour of the contact surface of the test piece, the magnetic contact fit between the test piece and the magnetic test piece 1 is improved, thereby improving the magnetic detection effect of the test piece.

[0093] Specifically, the profile tolerance of the inspection surface 12 is less than or equal to ±0.05mm.

[0094] This application ensures the machining accuracy of the magnetic test piece by controlling the contour of the test surface 12, so that the magnetic test piece forms the target magnetic force, and uses the magnetic force of the magnetic test piece as the standard for detecting magnetic force.

[0095] Specifically, the detection surface 12 is also provided with a magnetic component observation hole 14, which is connected to the magnetic component receiving groove 11.

[0096] This application provides a magnetic component observation hole 14, which facilitates observation of the installation position of the magnetic component in the magnetic component receiving groove 11, reduces the installation difficulty of the magnetic component, and effectively ensures that the magnetic component is installed in the target position in the magnetic component receiving groove 11.

[0097] Specifically, the magnetic component observation holes 14 correspond one-to-one with the magnetic component receiving slots 11. Each magnetic component receiving slot 11 has two magnetic component observation holes 14 on its corresponding detection surface 12. Please refer to [reference needed]. Figure 2 , Figure 2 The present invention relates to a schematic diagram of a magnetic force testing system in an embodiment of the application.

[0098] Specifically, the detection surface 12 of the magnetic force test piece 1 protrudes from the position fixing piece 2.

[0099] This application sets the detection surface 12 of the magnetic test piece 1 to protrude from the position fixing member 2, while the other opposite surface of the detection surface of the magnetic test piece 1 does not protrude from the position fixing member 2, forming a clear contrast, making it easy to distinguish which side of the magnetic test piece 1 is the detection surface. Furthermore, the detection surface 12 of the magnetic test piece 1 and the position fixing member 2 form a spatial three-dimensional interlacing, preventing the position fixing member 2 from hindering the detection process of the magnetic test piece 1 and improving the overall detection effect of the magnetic test piece 1.

[0100] Specifically, the magnetic test piece 1 includes a grooved surface 13; the grooved surface 13 is disposed opposite to the test surface 12; and a plurality of magnetic component receiving grooves 11 are disposed on the grooved surface 13.

[0101] By providing a grooved surface 13, this application effectively reduces manufacturing costs and minimizes the molding space of the magnetic test piece 1, while ensuring that the grooved surface 13 can accommodate the magnetic component.

[0102] Specifically, the magnetic component can be a magnet.

[0103] Specifically, the number of magnetic components corresponds one-to-one with the number of magnetic component receiving slots 11, and both the number of magnetic components and the number of magnetic component receiving slots 11 are 31.

[0104] Specifically, the length of the magnetic component receiving groove 11 can be 3.03 mm, and the width of the magnetic component receiving groove 11 can be 1.05 mm.

[0105] Specifically, the length and width tolerances of the magnetic component receiving groove 11 are less than or equal to ±0.02mm.

[0106] This application ensures the machining accuracy of the magnetic test piece by controlling the machining length and machining width of the magnetic component receiving groove 11, so that the magnetic test piece forms the target magnetic force, and uses the magnetic force of the magnetic test piece as the standard for detecting magnetic force.

[0107] Specifically, the wall thickness tolerance of the magnetic component receiving groove 11 is less than or equal to ±0.01mm, and the position tolerance of the magnetic component receiving groove 11 is less than or equal to ±0.05mm.

[0108] This application further controls the positional accuracy and wall thickness of the magnetic component receiving groove 11 to ensure the processing accuracy of the magnetic force test piece, so that the magnetic force test piece forms the target magnetic force, and uses the magnetic force of the magnetic force test piece as the standard for detecting magnetic force.

[0109] Specifically, the magnetic component receiving groove 11 is bonded to the magnetic component, allowing the magnetic component to move within the magnetic component receiving groove 11. The magnetic component is fixed within the magnetic component receiving groove 11 by applying adhesive. The adhesive can be 502 glue.

[0110] Specifically, the positioning components include a first positioning component and a second positioning component. The first and second positioning components have the same structure and are both positioning blocks. The component to be tested includes a detection end and a fixed end. The first positioning component is used to fix the detection end of the component to be tested to ensure that the component to be tested will not be displaced during the testing process. The second positioning component is used to fix the fixed end of the component to be tested. The stability of the component to be tested in magnetic testing is enhanced by fixing it at both ends.

[0111] Specifically, the position fixing component 2 is set on the outer periphery of the magnetic force test piece 1, and the magnetic force test piece 1 has a hollow structure.

[0112] This application uses a positioning fixing member 2 set on the outer periphery of the magnetic force test piece 1. When the magnetic force test piece 1 moves away from the test piece to perform magnetic force testing, the magnetic force test piece 1 is relatively located inside the whole structure, which improves the testing stability of the magnetic force test piece 1. The magnetic force test piece 1 has a hollow structure, which saves space and cost.

[0113] Specifically, it also includes a tension sensor; the tension sensor is communicatively connected to the controller; the tension sensor is used to collect magnetic force data between the magnetic test piece 1 and the test piece as the magnetic test piece 1 moves away from the test piece, and sends the magnetic force data to the controller, so that the controller can perform magnetic force detection based on the magnetic force data and the distance between the magnetic test piece 1 and the test piece to obtain the magnetic force test result. It should be noted that the magnetic force test result indicates whether the magnetic force effect generated by the test piece is qualified.

[0114] This application, by setting up a tension sensor, allows for real-time observation of the magnetic force change between the magnetic test piece and the test piece during the magnetic force detection process as the magnetic test piece moves away from the test piece after magnetic connection. This provides a specific magnetic force change value and improves the detection effect of the entire magnetic force detection process.

[0115] Specifically, the magnetic data may include, but is not limited to, a curve showing the change in force between the magnetic test piece 1 and the test piece. During the magnetic test, as the magnetic test piece 1 moves away from the test piece, a real-time curve showing the change in force as the distance between the magnetic test piece 1 and the test piece changes is acquired. Please refer to [reference needed] for details. Figure 4 As shown in the figure, the distance between the magnetic test piece 1 and the test piece gradually increases, while the force between the magnetic test piece 1 and the test piece first increases to the peak value of the magnetic force and then decreases, gradually approaching 0.

[0116] Specifically, the position fixing component 2 is provided with 6 mounting holes 21; the position fixing component 2 is fixed to the tension sensor through the mounting holes 21.

[0117] This application improves the stability of magnetic force testing by providing mounting holes 21 on the position fixing component 2 and fixing the position fixing component 2 to the tension sensor through the mounting holes 21, which means fixing the magnetic force testing component 1 to the tension sensor.

[0118] Specifically, the tension sensor includes a mounting plate with a mounting hole 21 and a fixing hole matching the mounting hole 21. Fasteners are inserted into both the mounting hole 21 and the fixing hole to fix the position fixing member 2 to the mounting plate.

[0119] Specifically, it also includes positioning pins. The position fixing component 2 is provided with two positioning pin holes 22. The positioning pins are inserted into the positioning pin holes 22 to position the position fixing component 2 between itself and the tension sensor, that is, to position the magnetic force test component 1 between itself and the tension sensor, and to determine the fixed position of the position fixing component 2 and the magnetic force test component 1.

[0120] Specifically, during the magnetic force test of the test piece, after the magnetic test piece 1 is magnetically connected to the test piece, the magnetic test piece 1 is controlled to move away from the test piece until the distance between the magnetic test piece and the test piece is greater than or equal to a preset distance. The preset distance can be 5mm, and the speed at which the magnetic test piece 1 moves away from the test piece can be 0.65mm / s.

[0121] By adopting the above technical solution, the magnetic force testing system disclosed in this application has the following beneficial effects:

[0122] This application uses the magnetic force generated by a magnetic test piece as a magnetic standard, and uses the magnetic test piece to replace the actual part to perform magnetic force testing on the part under test. During the magnetic force testing process, the magnetic test piece is controlled to move until it magnetically connects with the part under test on the positioning part. In response to the magnetic connection between the magnetic test piece and the part under test, the magnetic test piece is controlled to move away from the part under test until the distance between the magnetic test piece and the part under test is greater than or equal to a preset distance. The magnetic force test results of the part under test are obtained during the movement of the magnetic test piece. The entire testing process is simple to operate, improves the detection efficiency and stability of magnetic force testing, as well as the installation stability of each part.

[0123] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
