Description

Technical Field

[0001] This invention belongs to the field of magnetic property testing technology, and more specifically, it relates to a testing platform for the magnetization performance of soft magnetic materials. Background Technology

[0002] Soft magnetic materials are a class of materials that exhibit high permeability and low coercivity in weak magnetic fields. These materials are widely used in the radio electronics industry, precision instruments, and remote and automatic control systems, primarily for energy conversion and information processing.

[0003] Currently, the magnetic properties of soft magnetic materials cannot be directly measured after they are processed into finished products. Therefore, it is necessary to use a coil holder to connect the soft magnetic material and the coil holder for magnetization performance testing. However, the existing magnetization testing procedure requires staff to connect and install the soft magnetic material and the coil holder one by one. After the test is completed, the coil holder and the soft magnetic material need to be separated and disassembled. However, this method has low testing efficiency for soft magnetic materials and requires staff to operate continuously, which is time-consuming and labor-intensive. Summary of the Invention

The transmission gear has a protrusion on the side away from the bearing plate, and the pushing part is used to contact and press against the protrusion. The pushing part and the gear structure are located on the same side of the rotating frame.

[0008] In one possible implementation, the protrusion has an inclined guide surface, and the pushing part has a mating surface that contacts the inclined guide surface.

[0009] In one possible implementation, the actuating component further includes an extension rod located outside the mounting bracket, the extension rod being fixedly connected to the pivot of the support block; a pull ring is provided at one end of the extension rod away from the mounting bracket, and a connecting bracket and an elastic element are provided on the test plate, with both ends of the elastic element being connected to the pull ring and the connecting bracket, respectively.

[0010] In one possible implementation, the connecting frame includes a connecting block, a screw, and a locking nut. The connecting block is fixed to the test plate and located on one side of the turntable. The connecting block has a screw hole, the screw is rotatably connected to the screw hole, and the locking nut is screwed to the screw. One end of the elastic element is fixedly connected to the screw.

[0011] In one possible implementation, the coil support disk has an inclined storage surface for mounting in conjunction with the oscillating test piece disk.

[0012] In one possible implementation, the testing platform for the magnetization performance of the soft magnetic material further includes a drive mechanism for driving the test plate to rotate. The test plate is provided with an arc-shaped groove, and the support plate is located above the arc-shaped groove. The free end of the driver passes through one end of the arc-shaped groove and is arranged adjacent to the support plate. The drive component controls the support plate to flip, and the drive mechanism controls the flipped support plate to move above the coil support disk.

[0015] The beneficial effects of the testing platform for the magnetization performance of soft magnetic materials provided by this invention are as follows: Compared with the prior art, the testing platform for the magnetization performance of soft magnetic materials of this invention places a coil support disk filled with coil supports into the mounting hole of the transport mechanism and supports it on the support. The transport mechanism transports the coil support disk to one end of the transport mechanism and into contact with the limiting plate. Then, the driver is activated, and the free end of the driver moves from bottom to top, passes through the clearance hole and enters the corresponding mounting hole, lifting the coil support disk. The driver is then activated to move in the reverse direction, moving the coil support disk from the transport mechanism to the test plate. At the same time, the test piece disk is mounted on the carrier plate, and the drive component on the flipping and swinging mechanism is activated. The carrier plate mounted on the actuator first flips, moving the test piece disk to the lower surface of the carrier plate. Then, the actuator controls the carrier plate to swing downwards, causing the test piece disk on the carrier plate to align with the coil support disk, thus completing the connection between the soft magnetic material and the coil support and successfully completing the magnetization performance test. In this way, the operator only needs to place the coil support disk and the test piece disk on the transport mechanism and the carrier plate respectively, and use the transport mechanism, driver, actuator, and drive assembly to assemble the coil support disk and the test piece disk, which improves the efficiency of the magnetization performance test of soft magnetic materials and also saves time and effort.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Please see Figures 1 to 10The present invention will now describe the testing platform for the magnetization performance of soft magnetic materials. A testing platform for the magnetization performance of soft magnetic materials includes a transport mechanism 1, a limiting plate 2, a testing plate 3, a driver 4, a mounting frame 5, a tilting and swinging mechanism 6, and a support plate 7. The transport mechanism 1 has multiple mounting holes 11 and clearance holes 12, with each mounting hole 11 located between two adjacent clearance holes 12. A support 13 for mounting a coil support plate is provided within each mounting hole 11. The limiting plate 2 is mounted at one end of the transport mechanism 1 to limit the movement of the coil support plate. The testing plate 3 is located below the transport mechanism 1. The driver 4 is fixed on the testing plate 3 and located near the limiting plate 2. One side of the input mechanism 1; the free end of the driver 4 passes through the clearance hole 12 and enters the mounting hole 11 to support the coil support plate; the mounting bracket 5 is fixed on the test plate 3, and the mounting bracket 5 is provided with a mounting groove 51; the flipping swing mechanism 6 is mounted on the test plate 3 and is located on one side of the driver 4; the flipping swing mechanism includes an execution component 61 and a drive component 62 that is drively connected to the execution component 61. The execution component 61 is mounted in the mounting groove 51 and has horizontal flipping freedom and vertical swing freedom; the support plate 7 is mounted on one end of the execution component 61 and is used to mount the test plate.

[0034] The testing platform for the magnetization performance of soft magnetic materials provided by this invention, compared with the prior art, places a coil support disk filled with coil supports into the mounting hole 11 of the transport mechanism 1 and supports it on the support 13. The transport mechanism 1 transports the coil support disk to one end of the transport mechanism 1 and contacts the limiting plate 2. Then, the driver 4 is activated, and the free end of the driver 4 moves from bottom to top, passes through the clearance hole 12 and enters the corresponding mounting hole 11, lifting the coil support disk. The driver 4 is then activated to move in the reverse direction, moving the coil support disk from the transport mechanism 1 to the test plate 3. At the same time, the test piece disk is mounted on the carrier plate 7. The drive component 62 on the flipping swing mechanism 6 is activated, controlling the components installed on the execution component. The carrier plate 7 on 61 first flips over, moving the test piece disk to the lower end surface of the carrier plate 7. Then, the actuator 61 controls the carrier plate 7 to swing downwards, causing the test piece disk on the carrier plate 7 to dock with the coil support disk, completing the connection between the soft magnetic material and the coil support, thus successfully completing the magnetization performance test. In this way, the operator only needs to place the coil support disk and the test piece disk on the transport mechanism 1 and the carrier plate 7 respectively, and use the transport mechanism 1, the driver 4, the actuator 61 and the drive component 62 to achieve the docking and assembly of the coil support disk and the test piece disk, which improves the efficiency of the magnetization performance test of soft magnetic materials and also achieves the purpose of saving time and effort.

[0035] An electromagnet is installed on the support plate 7 to fix the test piece disk on the support plate 7 by magnetic attraction. After the coil support disk and the test piece disk are connected and installed, the electromagnet is turned off, allowing the coil support disk and the test piece disk to be smoothly removed. The driver 4 is a cylinder, electric push rod, etc. The driver 4 can be installed at the lower end of the test plate 3, and its free end can slide through the test plate 3.

[0036] Please see Figures 1 to 6 As a specific embodiment of the testing platform for the magnetization performance of soft magnetic materials provided by the present invention, the execution component 61 includes a bearing block 611, a support shaft 612, and a transmission gear 613. The bearing block 611 is rotatably connected to the mounting frame 5. The bearing block 611 has a rotating hole. The support shaft 612 is installed in the rotating hole and rotatably connected to the bearing block 611. The support shaft 612 passes through the rotating hole. The bearing plate 7 is installed at one end of the support shaft 612, and the transmission gear 613 is installed at the other end of the support shaft 612. The drive component 62 includes a rotating frame 621, a gear structure 622, and... The pushing part 623 and the toothed structure 622 are mounted on the rotating frame 621 and mesh with the transmission gear 613. The pushing part 623 is used to push the support shaft 612 to a horizontal position. The rotating frame 621 is activated to control the rotation of the toothed structure 622 and the pushing part 623. When the pushing part 623 contacts the support shaft 612 or the transmission gear 613, the support shaft 612 changes from an inclined position to a horizontal position. Simultaneously, the toothed structure 622 engages with the transmission gear 613, thereby driving the transmission gear 613 and the support shaft 612 to rotate, causing the bearing plate 7 to flip. After the flipping action is completed, the pushing part 623 and the toothed structure 622 move away from the transmission gear 613 and the support shaft 612. Therefore, the bearing block 611 swings downward in the mounting groove 51 of the mounting frame 5, allowing the coil support disk to align with the test piece disk, thus completing the flipping and swinging actions. A rotating hole is provided on the bearing block 611, and the support shaft 612 is rotatably connected in the rotating hole. The support shaft 612 is keyed to the transmission gear 613. Therefore, the rotation of the transmission gear 613 drives the support shaft 612 and the bearing plate 7 to rotate stably.

[0037] Please see Figure 1 and Figure 4As a specific embodiment of the testing platform for the magnetization performance of soft magnetic materials provided by the present invention, the rotating frame 621 includes a turntable 63, a vertical rod 631, a top plate 632, and a drive motor 633. The turntable 63 is rotatably connected to the test plate 3, and the drive motor 633 is driven by the turntable 63 to drive the turntable 63 to rotate. A gear structure 622 is mounted on the turntable 63. The vertical rod 631 is fixed on the turntable 63, and the central axis of the vertical rod 631 is collinear with the rotation center of the turntable 63. The top plate 632 is mounted on the upper end of the vertical rod 631, and a pushing part 623 is mounted on the top plate 632, with one end extending toward the support shaft 612. A protrusion 64 is provided on the side of the transmission gear 613 away from the bearing plate 7, and the pushing part 623 is used to engage with the protrusion. Part 64 contacts and presses against the protrusion 64; the pushing part 623 and the tooth structure 622 are located on the same side of the rotating frame 621; when the rotating frame 621 rotates, the drive motor 633 needs to be started. The drive motor 633 drives the turntable 63, the vertical rod 631 and the top plate 632 to rotate together. The pushing part 623 and the tooth structure 622 both move towards the transmission gear 613. The pushing part 623 contacts the protrusion on the transmission gear 613, pressing the axis of the transmission gear 613 from an inclined state to a horizontal state, and the support shaft 612 is arranged horizontally. Then the tooth structure 622 and the transmission gear 613 mesh smoothly and are connected. The tooth structure 622 drives the transmission gear 613 to rotate 180 degrees, completing the flipping action of the bearing plate 7 and the test piece disk. The length of the tooth structure 622 is sufficient to drive the transmission gear 613 to rotate 180 degrees, and the pushing part 623 has a range of motion to ensure that the transmission gear 613 can rotate smoothly 180 degrees while the support shaft 612 is in a horizontal position.

[0038] The turntable 63, vertical rod 631 and top plate 632 are in the shape of an I-beam. The tooth structure 622 is arranged in an arc on the upper end surface of the turntable 63. The pushing part 623 is fixed on the lower end surface of the top plate 632 and extends toward the protrusion 64 on the transmission gear 613.

[0039] Please see Figure 4 and Figure 6 As a specific embodiment of the testing platform for the magnetization performance of soft magnetic materials provided by the present invention, the protrusion 64 is provided with an inclined guide surface 641, and the pushing part 623 is provided with a mating surface that contacts the inclined guide surface 641. The protrusion 64 and the pushing part 623 are respectively provided with an inclined guide surface 641 and a mating surface. Under the drive of the turntable 63, the mating surface on the pushing part 623 contacts the inclined guide surface 641, thereby causing the pushing part 623 to smoothly squeeze and push the transmission gear 613 to swing upward.

[0040] Please see Figure 1 , Figure 4 and Figure 5As a specific embodiment of the testing platform for the magnetization performance of soft magnetic materials provided by the present invention, the execution component 61 also includes an extension rod 65 located outside the mounting frame 5. The extension rod 65 is fixedly connected to the rotating shaft of the bearing block 611. A pull ring 651 is provided at one end of the extension rod 65 away from the mounting frame 5. A connecting frame 66 and an elastic element 661 are provided on the test plate 3. The two ends of the elastic element 661 are respectively connected to the pull ring 651 and the connecting frame 66. In order to make the bearing plate 7 swing down stably to the tilted state, the extension rod 65 is set outside the mounting frame 5, and a pull ring 651 is set on the extension rod 65. At the same time, a connecting frame 66 corresponding to the pull ring 651 is set on the test plate 3. An elastic element 661 is set between the connecting element and the pull ring 651. With the restoring force of the elastic element 661, the support shaft 612 and the bearing block 611 swing, thereby making the bearing plate 7 move down and dock with the coil support plate.

[0041] Please see Figure 1 , Figure 4 and Figure 7 As a specific embodiment of the testing platform for the magnetization performance of soft magnetic materials provided by the present invention, the connecting frame 66 includes a connecting block 662, a screw 663, and a locking nut 664. The connecting block 662 is fixed on the test plate 3 and located on one side of the turntable 63. The connecting block 662 is provided with a screw hole, and the screw 663 is rotatably connected to the screw hole. The locking nut 664 is screwed to the screw 663. One end of the elastic element 661 is fixedly connected to the screw 663. By controlling the screw 663 to rotate in the screw hole, the helical motion is converted into linear motion, thereby changing the distance between the screw 663 and the pull ring 651. The restoring force of the spring installed between the pull ring 651 and the screw 663 is also adjusted, thereby adjusting the force on the bearing plate 7.

[0042] Please see Figure 2 and Figure 3 As a specific embodiment of the testing platform for the magnetization performance of soft magnetic materials provided by the present invention, the coil support disk has an inclined storage surface 14, which is used to cooperate with the test disk after swinging. Since the downward swinging support plate 7 changes from a horizontal state to an inclined state, the test disk installed on the support plate 7 is also in an inclined state when docking with the coil support disk. In order to improve the accuracy and reliability of the docking between the coil support disk and the test disk, the inclined storage surface 14 is provided on the coil support disk. Therefore, the test disk after swinging downward is parallel to the inclined storage surface 14, so that the test disk is accurately docked with the coil support disk, thereby completing the installation.

[0043] Please see Figures 1 to 3 , Figure 8As a specific embodiment of the testing platform for the magnetization performance of soft magnetic materials provided by the present invention, the testing platform for the magnetization performance of soft magnetic materials also includes a driving mechanism 8 for driving the test plate 3 to rotate. The test plate 3 is provided with an arc-shaped groove 31, and the support plate 7 is located above the arc-shaped groove 31. The free end of the driver 4 passes through one end of the arc-shaped groove 31 and is arranged adjacent to the support plate 7. The driving component 62 controls the support plate 7 to flip, and the driving mechanism 8 controls the flipped support plate 7 to move above the coil support disk. The driving component 62 controls the support plate 7 to move downward and make the test piece disk dock with the coil support disk. In order to avoid interference between the flipped support plate 7 and the coil support disk, the support plate 7 and the driver 4 are staggered. An arc-shaped groove 31 is provided on the test plate 3. Therefore, the flipping and swinging mechanism controls the support plate 7 to flip, and then the driving mechanism 8 is started to control the test plate 3 to rotate, so that the support plate 7 is located above the coil support disk on the driver 4. Then the flipping and swinging mechanism controls the support plate 7 to swing downward to realize the docking and installation of the test piece disk and the coil support disk.

[0044] Please see Figures 1 to 3 As a specific embodiment of the testing platform for the magnetization performance of soft magnetic materials provided by the present invention, a first pressure sensor 21 is provided on the limiting plate 2. The testing platform for the magnetization performance of soft magnetic materials also includes a control unit 9. The transport mechanism 1, the first pressure sensor 21, the driver 4, and the drive assembly 62 are all electrically connected to the control unit 9. When the transport mechanism 1 transports the coil support disk to contact the limiting plate 2, the coil support disk contacts the first pressure sensor 21 on the limiting plate 2 and triggers the first pressure sensor 21. The first pressure sensor 21 transmits the signal to the control unit 9. After analyzing and processing the signal, the control unit 9 starts the transport mechanism 1, the driver 4, and the drive assembly 62 to operate.

[0045] Please see Figure 1 , Figure 9 and Figure 10As a specific embodiment of the testing platform for the magnetization performance of soft magnetic materials provided by the present invention, a second pressure sensor 15 is provided on the support 13, and a sliding groove is provided on the inner wall of the mounting hole 11. One end of the support 13 is slidably connected to the sliding groove. A plurality of pushers 16 are provided on the transport mechanism 1, and each pusher 16 corresponds to a mounting hole 11. The free end of the pusher 16 is connected to the support 13 and is used to drive the support 13 to slide. The coil support disk is supported on the support 13 and pressed against the second pressure sensor 15. The second pressure sensor 15 is electrically connected to the control unit 9. After the transport mechanism 1 transports the coil support disk into place, it contacts the first pressure sensor 21 on the limiting plate 2. Pressure sensor 21 sends a signal to control unit 9, which controls the actuator 4 to move. The free end of actuator 4 moves upward to pass through clearance hole 12 and enters mounting hole 11. The free end of actuator 4 contacts the lower end of coil support plate and lifts coil support plate, separating coil support plate from first pressure sensor 21. First pressure sensor 21 triggers pusher 16, which controls support 13 to slide inward in sliding groove, so that support 13 is hidden on the inner wall of mounting hole 11, so that support 13 does not affect the movement of coil support plate. Under the action of actuator 4, coil support plate moves downward through mounting hole 11 and clearance hole 12 and is located on test plate 3. After the coil support plate and the test piece plate are assembled, the starter 4 drives the assembled coil support plate and the test piece plate upwards, passing through the clearance hole 12 and entering the mounting hole 11, above the sliding groove. Then, the pusher 16 pushes the support 13 towards the mounting hole 11, so that the support 13 is located inside the mounting hole 11, thereby transporting the assembled coil support plate and the test piece plate away. Reverse starting the transport mechanism 1 will transport the assembled coil support plate and the test piece plate. A locking component can be provided on the transport mechanism 1 to lock and fix the assembled coil support plate and the test piece plate.
