Description

Technical Field

[0001] This invention relates to the field of magnetic diode testing, specifically to a magnetic diode testing device. Background Technology

[0002] Magnetic material diodes are electronic components that utilize the saturation magnetic induction intensity and nonlinear characteristics of the hysteresis loop of magnetic materials to achieve unidirectional conductivity. Their basic structure consists of magnetic materials and conductive metals. By controlling the saturation magnetic induction intensity and nonlinear characteristics of the hysteresis loop generated by the magnetic field on the magnetic material, the unidirectional conductivity effect of the diode is achieved. During the production and processing of magnetic material diodes, testing institutions are required to test them to ensure that they can work properly.

[0003] Existing diode testing mechanisms have some problems in actual operation. For example, a diode production testing device with publication number CN114089146B can adjust the distance between two testing plates according to the distance between the diode pins, but it cannot perform convenient and stable batch loading of diodes when testing multiple diodes. Therefore, before starting the test, the staff needs to place and load the diodes one by one, resulting in low testing efficiency. In addition, existing testing mechanisms cannot conveniently test the working state of magnetic diodes in a magnetic field environment, and cannot effectively reduce the interference of the surrounding magnetic field, making them less practical. Therefore, there is a need to provide a magnetic diode testing device to meet the needs of users. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention includes a positioning and feeding assembly. Utilizing the cooperation of the first baffle, the second baffle, and the top plate, repeated pressing, combined with the positioning groove and positioning plate, facilitates the convenient positioning and disassembly of the trays. This enables convenient and stable batch loading and unloading of magnetic diode bodies, effectively improving the testing efficiency of the magnetic diodes. Furthermore, the alternating feeding of the two trays further enhances the batch loading efficiency of the magnetic diode bodies, further improving the working efficiency of the testing mechanism. The rotation of the bidirectional threaded rod allows for convenient adjustment of the distance between the first and second conductive plates, while the rotation of the unidirectional threaded rod allows for convenient adjustment of the height of the first and second conductive plates individually. This enables convenient and stable positioning and conductivity of magnetic diode body pins with different spacings and length differences, ensuring the stability and accuracy of subsequent magnetic diode body testing and effectively improving the practicality and applicability of the testing mechanism.

[0017] 2. This invention includes an automatic protection component. A hydraulic rod drives the protective plate downwards. When a magnetic field is applied to the magnetic diode body for testing, combined with the fixed frame and copper coil, the fixed frame pushes the rubber piston downwards via a push rod. This automatically inflates the rubber airbag, causing the second and third protective frames within the first protective frame to extend upwards automatically, thus automatically completing the magnetic field shielding. This reduces interference from the surrounding magnetic field on the magnetic diode body testing, further improving the stability and accuracy of subsequent magnetic diode body testing, and increasing the versatility and stability of the testing mechanism.

[0018] 3. This invention incorporates a high-efficiency cooling component. During testing, driven by a servo motor, and in conjunction with circular and internal gears, each screw rod automatically rotates during its revolution, continuously supplying coolant from the insulation frame to the heat exchange tubes and completing coolant circulation. Simultaneously, based on the heat exchange principle and the continuous rotation of exhaust fans, each magnetic diode body undergoes continuous and uniform cooling during testing, preventing overheating of a batch of magnetic diode bodies and thus protecting the testing mechanism from damage. This enhances the stability and safety of the testing mechanism. Attached Figure Description

The end cross-sections of the first baffle 203, the second baffle 205, and the top plate 209 are all right-angled triangles. By using the cooperation of the first baffle 203, the second baffle 205, and the top plate 209, and by repeatedly pressing, the positioning grooves 201 and the positioning plates 207 can be combined to easily complete the positioning and disassembly of the support plate 206.

[0046] In this embodiment, five bidirectional threaded rods 211 are provided, equidistantly distributed within the support plate 206. Adjacent bidirectional threaded rods 211 are welded together, and the outermost bidirectional threaded rod 211 is welded to the rotating rod 210. Five sets of sliding plates 212 are provided, each corresponding to one of the five bidirectional threaded rods 211. Each set of sliding plates 212 has two sliding plates, symmetrically distributed on both sides of the bidirectional threaded rod 211. A unidirectional threaded rod 213 is rotatably connected to the top surface of the sliding plate 212. Five conductive plates 215 and five second conductive plates 216 are provided. Insulating plates 214 are fixedly connected to the bottom surfaces of both the first conductive plate 215 and the second conductive plate 216. The insulating plates 214 are threaded onto the unidirectional threaded rod 213. The first conductive plates 215 are positioned above the left sliding plate 212 of the bidirectional threaded rod 211, and the second conductive plates 216 are positioned above the right sliding plate 212 of the bidirectional threaded rod 211.

[0047] In this embodiment, the automatic protection component 5 includes an air storage frame 501 and a first protective frame 507. Both the air storage frame 501 and the first protective frame 507 are welded and fixed to the fixing plate 1. The air storage frames 501 are symmetrically distributed on both sides of the fixing plate 1.

The fixed frame 10 can push the rubber piston 504 to move automatically downward through the push rod 505, thereby automatically inflating the rubber airbag 510. This drives the second protective frame 508 and the third protective frame 509 inside the first protective frame 507 to automatically extend upward, automatically completing the magnetic field shielding work and reducing the interference of the magnetic field in the surrounding environment on the testing of the magnetic diode body 4.

[0048] In this embodiment, the high-efficiency cooling component 6 includes a filter frame 601, which is welded and fixed to the center of the fixing plate 1. The top surface of the filter frame 601 is flush with the top surface of the fixing plate 1. A heat insulation frame 602 is welded and fixed to the bottom of the filter frame 601. A cooling element 603 is installed and fixed to the bottom of the heat insulation frame 602. A servo motor 604 is welded and fixed to the center of the bottom of the heat insulation frame 602. A sealing plate 605 is welded and fixed to the output shaft of the servo motor 604. The sealing plate 605 is rotatably connected to the heat insulation frame 602 through a sealing bearing. A conveying cylinder 606 is welded and fixed to the bottom surface of the sealing plate 605. A stirring plate 612 is welded and fixed to both sides of the conveying cylinder 606. A heat exchange tube 607 is connected to the top side of the conveying cylinder 606. The heat exchange tubes 607 are distributed at equal angles on the conveying cylinder 606. A spiral rod 608 is rotatably connected to the sealing plate 605. Inside the conveying cylinder 606, the conveying cylinders 606 are evenly distributed on the sealing plate 605. The conveying cylinders 606 correspond one-to-one with the screw rods 608. A circular gear 609 is welded and fixed to the bottom end of the screw rod 608. An internal gear 610 is meshed and connected to the circular gear 609. The internal gear 610 is welded and fixed to the bottom surface inside the heat insulation frame 602. An exhaust fan 611 is welded and fixed to the top end of the screw rod 608. During the test, driven by the servo motor 604, combined with the circular gear 609 and the internal gear 610, each screw rod 608 can be driven to rotate automatically during the revolution. This allows the coolant in the heat insulation frame 602 to be continuously delivered to the heat exchange tube 607 and the coolant to circulate. At this time, under the principle of heat exchange, combined with the continuous rotation of each exhaust fan 611, the magnetic diode body 4 can be continuously and uniformly cooled during the test.

[0049] It should be noted that this invention is a magnetic diode testing device. Since the spacing and length difference between the two pins of different specifications of the magnetic diode body 4 are different, the operator can first rotate the rotating rod 210 on the support plate 206. The rotation of the rotating rod 210 will drive each bidirectional threaded rod 211 to rotate simultaneously, thereby driving the sliding plates 212 on both sides of the bidirectional threaded rod 211 to move simultaneously towards the center or sides. Under the movement of the sliding plates 212, the insulating plate 214 on the unidirectional threaded rod 213 will drive the first conductive plate 215 and the second conductive plate 216 on both sides to move simultaneously towards the center or sides, ensuring that the two pins of the magnetic diode body 4 can be inserted into the slots 217 on the first conductive plate 215 and the second conductive plate 216 respectively. Furthermore, the longer positive pin of the magnetic diode body 4 needs to be inserted into the slot 217 on the first conductive plate 215. Inside, the shorter negative lead of the magnetic diode body 4 is inserted into the slot 217 on the second conductive plate 216. Then, the operator can simultaneously rotate the one-way threaded rods 213 on both sides of the slide plate 212. Under the simultaneous rotation of the one-way threaded rods 213 on both sides, the threaded insulating plate 214 can be driven to move up or down, which in turn can drive the first conductive plate 215 or the second conductive plate 216 to move up or down, ensuring that the two leads on the magnetic diode body 4 can be stably inserted into the slots 217 on the first conductive plate 215 and the second conductive plate 216, thus ensuring the stability of subsequent testing. Since the leads of the magnetic diode bodies 4 in the same batch are the same, only one adjustment is needed when testing the same batch of magnetic diode bodies 4. When testing the next batch of magnetic diode bodies 4, another adjustment is required.

[0050] After the pins of multiple magnetic diode bodies 4 are stably placed in the slots 217 of the first conductive plates 215 and the corresponding second conductive plates 216, the support plate 206 can be lifted and placed on the rubber frame 3 in the middle of the fixing plate 1 and pressed down. At this time, the support plate 206 can drive the positioning plate 207 to insert into the positioning groove 201, and the support plate 206 can drive the top plate 209 to contact the first baffle 203 on the connecting plate 202. Under the downward pressure of the support plate 206, the support plate 206 can drive the top plate 209 synchronously through the positioning plate 207. As it moves downward, the top plate 209 is automatically pushed into the positioning plate 207 by the guiding and pushing action of the inclined surface at the end of the first baffle 203 until the positioning plate 207 drives the top plate 209 to move downward to below the first baffle 203. At this time, under the elastic action of the first spring 204, the top plate 209 can be automatically moved outward to reset. Under the action of the top plane of the top plate 209 and the bottom plane of the first baffle 203, a stable engagement is achieved. Combined with the positioning plate 207 and the positioning groove 201, the engagement and positioning of the support plate 206 can be easily completed.

[0051] At this point, the operator can open the control switch on the first battery 222 by prying open the groove in the middle of the rubber frame 3. The positive terminal of the first battery 222 is then connected to the leftmost first conductive plate 215 via the third cable 220, and each first conductive plate 215 is connected via the first cable 218. Furthermore, each first conductive plate 215 is connected to the positive terminal of the magnetic diode body 4. Simultaneously, the negative terminal of the first battery 222 is connected to the rightmost second conductive plate 216 via the fourth cable 221, and each second conductive plate 216 is connected via the second cable 219. Each second conductive plate 216 is also connected to the negative terminal of the magnetic diode body 4. A stable test is then conducted, allowing the operator to visually assess whether each magnetic diode body 4 is functioning correctly.

[0052] Subsequently, the staff can drive the hydraulic rod 7 to move the protective plate 8 downward. During the downward movement of the protective plate 8, the fixed frame 10 can push the push rod 505 downward, which in turn can push the rubber piston 504 to move downward automatically. This allows the rubber airbag 510 to be automatically inflated through the air storage frame 501 and the air guide pipe 506. Under the inflation of the rubber airbag 510, the second protective frame 508 and the third protective frame 509 inside the first protective frame 507 can be pushed upward automatically to complete the extension and contact the protective plate 8. At this time, under the combined action of the second protective frame 508 and the third protective frame 509 made of shielding material, the interference of the magnetic field in the surrounding environment on the testing of the magnetic diode body 4 can be reduced, further improving the stability and accuracy of the subsequent testing of the magnetic diode body 4.

[0053] Under the downward movement of the fixed frame 10, each magnetic diode body 4 can be covered. At this time, the second battery 9 can be turned on. The second battery 9, together with the fixed frame 10 and the copper coil 11, can form a magnetic field in the fixed frame 10, thereby testing whether the magnetic diode body 4 can work normally in the magnetic field. The staff can make a direct observation through the transparent protective plate 8.

[0054] During the testing of the magnetic diode body 4, driven by the servo motor 604, the sealing plate 605 rotates via the output shaft, which in turn drives the various conveying cylinders 606 and the corresponding screw rods 608 to perform circular motion. During this circular motion, the screw rods 608 drive the bottom circular gear 609 to move synchronously within the internal gear 610. Through the meshing of the circular gear 609 and the internal gear 610, the screw rods 608 rotate automatically within the conveying cylinders 606, thereby discharging the coolant from the insulation frame 602. The coolant is continuously conveyed upwards and then transported again to the insulation frame 602 through each heat exchange tube 607. Under the stirring action of the stirring plate 612 and the cooling action of the cooling plate 603, the coolant maintains a continuous low temperature. During the continuous conveying process, the coolant can rapidly cool the air around the heat exchange tube 607 by utilizing the heat exchange tube 607 and the heat exchange principle. Subsequently, under the rotation action of each screw rod 608, the exhaust fan 611 in the filter frame 601 can draw in the external air and deliver the cooled air to each magnetic diode body 4 to achieve efficient cooling.

[0055] Furthermore, during the testing process, staff can use another tray 206 to batch-load the magnetic diode bodies 4, saving subsequent loading time. After the testing is completed, simply drive the hydraulic rod 7 to push the protective plate 8 upward to reset, and continue pressing the tray 206 downward. Similarly, under the obstruction of the second baffle 205 and the guiding action of the inclined surface at the end of the top plate 209, the second baffle 205 can push the top plate 209 to move back into the positioning plate 207 until the positioning plate 207 drives the top plate 209 downward to below the second baffle 205. At this time, under the elastic action of the first spring 204, the top plate 209 can be driven to automatically move outward to reset, and then the tray 206 can be released. At this time, the elastic force of the rubber frame 3 can push the tray 206 to move upward automatically. Since the elastic force of the second spring 208 is greater than the elastic force of the first spring 204, the tray 206... The top plate 209 on the positioning plate 207 can move the second baffle 205 upwards synchronously until the second baffle 205 contacts the first baffle 203. At this time, under the blocking action of the first baffle 203, combined with the inclined surface of the end of the second baffle 205, the top plate 209 can be pushed to move into the positioning plate 207 again until the positioning plate 207 drives the top plate 209 to move upwards and disengage from the first baffle 203, completing the automatic disassembly. In summary, by repeatedly pressing, combined with the positioning groove 201 and the positioning plate 207, the positioning and disassembly of the tray 206 can be conveniently completed, thereby enabling convenient and stable batch loading and unloading of the magnetic diode body 4, effectively improving the testing efficiency of the magnetic diode. Furthermore, by using the alternating loading of the two trays 206, the batch loading efficiency of the magnetic diode body 4 can be effectively improved, further enhancing the working efficiency of the testing mechanism.
