Description

Technical Field

[0001] This utility model relates to the field of nanomagnetic core functional testing technology, and in particular to a multifunctional tester for nanomagnetic cores. Background Technology

[0002] Nanomagnetic cores are magnetic materials with nanoscale dimensions, commonly used in the electronics and electrical fields, especially in high-frequency and miniaturized applications. To measure and characterize the various physical properties of nanomagnetic materials, multifunctional testers are often used to detect and evaluate the magnetic, electrical, and thermal properties of nanomagnetic cores.

[0003] According to the Chinese patent "A Magnetic Detection Device for Nanocrystalline Magnetic Cores" (authorization announcement number "CN219162348U"), the device uses a magnetic detector body, a first electric hydraulic cylinder, a slider, a second electric hydraulic cylinder, a connecting block, and a connecting ring to achieve lateral displacement of the magnetic detector body to detect the magnetic properties of different positions on the nanocrystalline magnetic core, thus ensuring the efficiency of the magnetic core detection.

[0004] While the aforementioned application can detect the top of the nanocrystalline magnetic core, it is inconvenient to detect the magnetism at the bottom of the nanocrystalline magnetic core, thus affecting the accuracy of the magnetism detection of the nanocrystalline magnetic core.

[0005] Therefore, a multifunctional tester for nanomagnetic cores is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a multifunctional tester for nanocrystalline magnetic cores to solve the above-mentioned problems, thereby improving the problem that although the top of the nanocrystalline magnetic core can be tested, it is inconvenient to test the magnetic properties of the bottom of the nanocrystalline magnetic core.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a multifunctional tester for nano-magnetic cores, comprising: a test chamber, wherein a magnetic detector and an electrical detector are provided on the upper surface of the test chamber, and a hot air blower is fixedly connected to the top of the test chamber; and an adjustment mechanism, wherein the adjustment mechanism is located inside the test chamber; wherein the adjustment mechanism includes a mounting bracket located at the lower end of the inner wall of the test chamber, a bidirectional lead screw is rotatably connected to the top of the mounting bracket, and two sliding brackets are threadedly connected to the surface of the bidirectional lead screw, wherein a first clamping block is rotatably connected to one side of one sliding bracket, and a second clamping block is rotatably connected to one side of the other sliding bracket, and an insulating pad is fixedly connected to one side of both the first and second clamping blocks, and the surface of the second clamping block is slidably connected to the inner wall of the first clamping block. By using a bidirectional lead screw, a shifting frame, a first clamping block, a second clamping block, and an insulating pad, flexible clamping of the nanomagnetic ring is achieved. The shifting frame, the first clamping block, and the second clamping block enable the nanomagnetic ring to be flipped, allowing the magnetic detector to detect the bottom of the nanomagnetic ring. Compared to existing methods that only detect the top of the nanomagnetic ring, this method can detect both the top and bottom of the nanomagnetic ring, ensuring the accuracy of the detection of the nanomagnetic ring's magnetism.

[0008] Preferably, a first bevel gear is fixedly connected to the bottom end of the mounting bracket, and a second bevel gear is meshed with the bottom end of the first bevel gear. The surface of the second bevel gear is rotatably connected to the lower end of the inner wall of the test chamber. A first servo motor is fixedly connected to the lower end of the inner wall of the test chamber, and the output shaft of the first servo motor is fixedly connected to one end of the second bevel gear. Through the first servo motor, the first bevel gear, and the second bevel gear, the clamped nanomagnetic ring rotates slowly, ensuring that the magnetic detector and the electrical detector can comprehensively detect the top and bottom ends of the nanomagnetic ring, thus improving the accuracy of detecting the magnetic and electrical properties of the nanomagnetic ring.

[0009] Preferably, a second servo motor is fixedly connected to one side of one of the moving frames, and the output shaft of the second servo motor is fixedly connected to one side of the first clamping block.

[0010] Preferably, a fixing rod is fixedly connected to both the top and bottom of one of the moving frames, and the upper surface of the second clamping block contacts the surface of one of the fixing rods. The fixing rods restrict the flipping of the first and second clamping blocks, ensuring that the bottom end of the nano-magnetic core can be precisely flipped upwards.

[0011] Preferably, an anti-deviation ring is fixedly connected to the inner bottom wall of the test chamber, and the lower end of the surface of the mounting bracket is rotatably connected to the inner wall of the anti-deviation ring. The anti-deviation ring restricts the rotational position of the mounting ring, preventing it from shifting during rotation.

[0012] Preferably, a baffle is fixedly connected to the lower end of the surface of the mounting bracket, and the bottom end of the baffle contacts the top end of the anti-deviation ring. The baffle seals the opening at the top of the anti-deviation ring, preventing dust and impurities from falling into the inner wall of the anti-deviation ring.

[0013] Preferably, a roller is rotatably connected to the lower end of the surface of the transfer frame, and the surface of the roller contacts the top of the mounting frame.

[0014] Preferably, a slide rod is fixedly connected to the upper surface of the mounting bracket, and the inner wall of the moving bracket is slidably connected to the surface of the slide rod. The slide rod limits the movement position of the moving bracket, preventing deviation of the bidirectional lead screw during the movement of the moving bracket.

[0015] The beneficial effects of this utility model are:

[0016] 1. By using a bidirectional lead screw, a shifting frame, a first clamping block, a second clamping block, and an insulating pad, flexible clamping of the nanomagnetic ring is achieved. The shifting frame, the first clamping block, and the second clamping block enable the position of the nanomagnetic ring to be flipped, allowing the magnetic detector to detect the bottom of the nanomagnetic ring. Compared with the existing method that only detects the top of the nanomagnetic ring, this method can detect both the top and bottom of the nanomagnetic ring, ensuring the accuracy of detecting the magnetism of the nanomagnetic ring.

[0017] 2. By using the first servo motor, the first bevel gear, and the second bevel gear, the clamped nanomagnetic ring is slowly rotated, ensuring that the magnetic detector and the electrical detector can fully detect the top and bottom of the nanomagnetic ring, thereby improving the accuracy of detecting the magnetic and electrical properties of the nanomagnetic ring.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In practical implementation: such as Figure 1-4 As shown, a multifunctional tester for nano-magnetic cores includes: a test chamber 1, with a magnetic detector 2 and an electrical detector 3 on the upper surface of the test chamber 1, and a hot air blower 4 fixedly connected to the top of the test chamber 1; and an adjustment mechanism 5 located inside the test chamber 1. The adjustment mechanism 5 includes a mounting bracket 51 located at the lower end of the inner wall of the test chamber 1, a bidirectional lead screw 52 rotatably connected to the top of the mounting bracket 51, and two sliding brackets 53 threadedly connected to the surface of the bidirectional lead screw 52. A first clamping block 54 is rotatably connected to one side of one sliding bracket 53, and a second clamping block 55 is rotatably connected to one side of the other sliding bracket 53. Insulating pads 56 are fixedly connected to one side of both the first and second clamping blocks 54. The surface of the second clamping block 55 is slidably connected to the inner wall of the first clamping block 54. A second servo motor 57 is fixedly connected to one side of one sliding bracket 53, and the output shaft of the second servo motor 57 is fixedly connected to one side of the first clamping block 54.

[0025] A temperature sensor is installed on one side of the inner wall of the test chamber 1. Two electric push rods are fixedly connected to the inner top wall of the test chamber 1. The telescopic end of one electric push rod is fixedly connected to the top of the magnetic detector 2, and the telescopic end of the other electric push rod is fixedly connected to the top of the electrical detector 3. The magnetic detector 2 adopts the principle of X-ray magnetic circular dichroism. XMCD is a technology based on synchrotron radiation source, which characterizes the magnetism of nanomagnetic cores by measuring the X-ray absorption spectrum of different spin states.

[0026] When performing multifunctional testing on the nano magnetic core, the nano magnetic core is placed between the first clamp 54 and the second clamp 55. The bidirectional lead screw 52 is rotated, which causes the two moving frames 53 to move closer together, bringing the first clamp 54 and the second clamp 55 closer together and clamping the nano magnetic core. One of the electric push rods is manually activated, and the telescopic end of the electric push rod moves down, causing the magnetic detector 2 to move down to a suitable height. Then, the electric push rod is manually closed. At this time, the magnetic detector 2 detects the top of the nano magnetic core. After the detection is completed, one of the electric push rods is manually activated, and the electric push rod moves up, causing the magnetic detector 2 to move up to a certain height. Then, the electric push rod is manually closed and the second servo motor 57 is activated. The output shaft of the second servo motor 57 rotates, causing the first clamp 54 to rotate. The rotation of the first clamp 54 causes the second clamp 55 to rotate, causing the clamped nano magnetic core to flip over, so that the bottom of the nano magnetic core flips to the top. At this time, the magnetic detector 2 performs magnetic detection on the nano magnetic core. The data after the detection is transmitted to the CNC platform so that the staff can understand the magnetic properties of the nano magnetic core.

[0027] After the nano-magnetic core is tested, the magnetic detector 2 is manually turned off and the electrical detector 3 is turned on. According to the above procedure, the electrical detector 3 performs electrical testing on the surface of the nano-magnetic core, and the hot air blower 4 is manually turned on to heat the test chamber 1. This allows the electrical detector 3 to test the electrical performance of the nano-magnetic core at different temperatures, in order to identify dielectric loss and conductivity changes caused by temperature variations. The test data is transmitted to the CNC platform so that the staff can understand the magnetic properties of the nano-magnetic core. After the test is completed, the electrical detector 3 and the hot air blower 4 are manually turned off.

[0028] like Figure 3 As shown, a first bevel gear 59 is fixedly connected to the bottom end of the mounting bracket 51, and a second bevel gear 510 is meshed with the bottom end of the first bevel gear 59. The surface of the second bevel gear 510 is rotatably connected to the lower end of the inner wall of the test chamber 1. A first servo motor 511 is fixedly connected to the lower end of the inner wall of the test chamber 1, and the output shaft of the first servo motor 511 is fixedly connected to one end of the second bevel gear 510.

[0029] The first servo motor 511 is manually turned on. The output shaft of the first servo motor 511 rotates, which drives the second bevel gear 510 to rotate. Since the diameter of the second bevel gear 510 is smaller than that of the first bevel gear 59, the specific gear diameter ratio is selected according to actual needs. The rotation of the second bevel gear 510 drives the first bevel gear 59 to rotate slowly. The slow rotation of the first bevel gear 59 drives the shift frame 53, the first clamping block 54, the second clamping block 55 and the nano magnetic core to rotate slowly, so that the magnetic detector 2 can perform comprehensive detection on the end of the nano magnetic core.

[0030] like Figure 4 As shown, a fixing rod 513 is fixedly connected to the top and bottom of one of the moving frames 53, and the upper surface of the second clamping block 55 contacts the surface of one of the fixing rods 513.

[0031] like Figure 3 As shown, an anti-deviation ring 512 is fixedly connected to the inner bottom wall of the test box 1. The lower end of the surface of the mounting bracket 51 is rotatably connected to the inner wall of the anti-deviation ring 512. A cover plate 58 is fixedly connected to the lower end of the surface of the mounting bracket 51. The bottom end of the cover plate 58 contacts the top end of the anti-deviation ring 512.

[0032] like Figure 3 As shown, a roller is rotatably connected to the lower end of the surface of the transfer frame 53, and the surface of the roller contacts the top of the mounting frame 51. A slide rod is fixedly connected to the upper end of the surface of the mounting frame 51, and the inner wall of the transfer frame 53 is slidably connected to the surface of the slide rod.

[0033] In use, the nano-magnetic core is placed between the first clamp 54 and the second clamp 55. Rotating the bidirectional lead screw 52 causes the two moving frames 53 to move closer together, bringing the first clamp 54 and the second clamp 55 closer together to clamp the nano-magnetic core. One of the electric push rods is manually activated, causing its extension end to move downwards, which in turn moves the magnetic detector 2 to a suitable height. Then, the electric push rod is manually deactivated, and the first servo motor 511 is activated. At this point, the magnetic detector 2 detects the top of the nano-magnetic core. The output shaft of the first servo motor 511 rotates, driving the moving frames 53, the first clamp 54, the second clamp 55, and the nano-magnetic core to rotate slowly via the second bevel gear 510 and the first bevel gear 59. This allows the magnetic detector 2 to detect the top of the nano-magnetic core. After a comprehensive inspection is conducted, one of the electric push rods is manually activated. The electric push rod moves upward, causing the magnetic detector 2 to move upward to a certain height. Then, one of the electric push rods is manually deactivated and the second servo motor 57 is activated. The output shaft of the second servo motor 57 rotates, causing the first clamping block 54, the second clamping block 55, and the held nano magnetic core to flip. When the surface of the second clamping block 55 contacts the fixed rod 513 below the shift frame 53 during rotation, it senses resistance and the second servo motor 57 automatically shuts off, allowing the bottom end of the nano magnetic core to flip precisely to the top. At this time, the magnetic detector 2 performs magnetic detection on the nano magnetic core. The data after detection is transmitted to the CNC platform for the staff to understand the magnetic properties of the nano magnetic core. After the detection is completed, the first servo motor 511 is manually deactivated.

[0034] It should be noted that the test box 1, magnetic detector 2, electrical detector 3, hot air blower 4, first servo motor 511, second servo motor 57, and electric push rod mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the power supply of magnetic detector 2, electrical detector 3, hot air blower 4, first servo motor 511, second servo motor 57, and electric push rod can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
