Description

Technical Field

[0001] This utility model belongs to the field of inductor testing technology, specifically relating to an automatic inductor performance tester. Background Technology

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. After the inductor is manufactured, it needs to be tested to ensure the quality of the inductor. This requires the use of inductor testing equipment.

[0003] For example, patent CN220305434U discloses an inductor testing fixture, which includes a worktable with four support legs and a placement mechanism set on the worktable for placing inductors. The placement mechanism includes a circular plate rotatably connected to the worktable. Multiple placement plates are provided on the side of the circular plate away from the worktable. Each placement plate is connected to the circular plate by four support rods arranged symmetrically in pairs. Each placement plate has a placement groove, and two placement tubes arranged symmetrically in pairs are slidably connected to each placement groove.

[0004] While the presence of multiple stations in the aforementioned inductor testing fixture can improve the overall efficiency of inductor performance testing, the spacing of the placement tubes for the two pins of the inductor to be placed in the multiple stations needs to be adjusted manually one by one. This adjustment method not only increases the complexity of inductor placement and testing operations, but also slows down the overall testing efficiency to some extent. Utility Model Content

[0005] (1) Technical problems to be solved To address the shortcomings of existing technologies, the purpose of this utility model is to provide an automatic inductor performance tester. While the presence of multiple workstations in existing technologies can improve the overall efficiency of inductor performance testing, the spacing of the placement tubes for the two pins of the inductor to be placed in these multiple workstations needs to be manually adjusted one by one. This adjustment method not only increases the complexity of inductor placement and testing but also slows down the overall testing efficiency to some extent.

[0006] (2) Technical solution To address the aforementioned technical problems, this utility model provides an automatic inductor performance tester, comprising a workbench, a movable platform movably mounted in the center of the workbench, and placement racks distributed around the top perimeter of the movable platform. A linkage adjustment mechanism is jointly mounted above the movable platform and in the center of the multiple placement racks. The linkage adjustment mechanism includes a ring-shaped frame, a gear plate, and a sliding placement tube, with a limit mechanism in the center of the sliding placement tube. A detection component is mounted on one side of the upper part of the workbench. The ring-shaped frame is fixed to the upper center of the movable platform, and a linkage component is provided in the center and above the ring-shaped frame. An adjustment component is mounted in the center of the multiple placement racks.

[0007] Furthermore, the linkage component includes a drive motor, which is installed in the upper center of the ring frame. The output end of the drive motor is connected to a rotating rod, and three gear sleeves are distributed around the rotating rod. Rack guide blocks are symmetrically meshed on different sides of the three gear sleeves. Support guides are distributed around the upper periphery of the movable platform. The bottom part of the ends of the multiple rack guide blocks is provided with meshing teeth, and a gear plate is meshed below the meshing teeth.

[0008] Furthermore, the support guide frame and its corresponding rack guide block are connected by a movable guide assembly.

[0009] Furthermore, the adjustment assembly includes positive and negative lead screws, which are installed on one side of the middle of the placement frame. Lead screw sleeves are screwed on both sides of the middle of the positive and negative lead screws, and sliding placement tubes are fixed on the inner side of a pair of lead screw sleeves. A sliding groove is opened on one side of the interior of the placement frame.

[0010] Furthermore, the chute and the sliding placement tube are horizontally and movably connected.

[0011] Furthermore, the limiting mechanism includes a female guide block, which is disposed around the middle periphery of the sliding placement tube. A spring is provided inside the female guide block, and a male guide block is connected to the end of the spring. An arc-shaped limiting block is connected to the end of the male guide block, and a baffle plate is fixed to the top of the inside of the female guide block.

[0012] Furthermore, the arc-shaped limiting block is connected to the sub-guide block via a mother guide block, a spring, and an elastic guide assembly.

[0013] (3) Beneficial effects Compared with the prior art, the beneficial effects of this utility model are as follows: This invention allows workers to pre-adjust the spacing of each pair of sliding placement tubes within multiple placement racks based on the pin spacing of inductors in the same batch. Specifically, the adjustment is as follows: Workers start the drive motor, causing the rotating rod and its three surrounding gear sleeves to rotate synchronously. At this time, the rack guide blocks, located on opposite sides of the three gear sleeves and meshing with them, will move relative to each other in coordination with the guide frame. Since each rack guide block has meshing teeth at its bottom end, and the meshing teeth's contact surfaces engage with a gear disc, the gear disc will rotate with the meshing action, driving the corresponding positive and negative lead screws to rotate. In this state, each pair of lead screw sleeves cooperating with the positive and negative lead screws will carry the corresponding fixed sliding placement tubes, moving relative to each other in coordination with the guide of the sliding groove, thereby achieving the purpose of synchronously adjusting the spacing of multiple pairs of sliding placement tubes within multiple placement racks.

[0014] This invention allows personnel to insert the inductor pins into the middle of a pair of sliding placement tubes within the placement rack. Since the sliding placement tubes are equipped with three sets of limiting mechanisms, the three arc-shaped limiting blocks, guided by the sliding of the female and female guide blocks and supported by the elasticity of the springs, stably clamp the inductor pins. After clamping, the inductor can be tested simply by using a pair of detection plates in the detection assembly in conjunction with a cylinder drive. Notably, a servo motor is installed below the workbench to drive the movable platform. This motor enables cyclic testing of multiple inductors on the movable platform, and during the testing process, personnel can simultaneously perform loading operations, thereby improving the efficiency of inductor testing.

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.

[0019] This specific embodiment is an automatic inductor performance tester, the structural schematic of which is shown below. Figures 1 to 4As shown, the system includes a workbench 1, a movable platform 2 movably mounted in the middle of the workbench 1, and placement racks 3 distributed around the top perimeter of the movable platform 2. A linkage adjustment mechanism 4 is jointly mounted above the movable platform 2 and in the middle of the multiple placement racks 3. The linkage adjustment mechanism 4 includes a ring-shaped frame 41, a gear plate 427, and a sliding placement tube 433. A limit mechanism 5 is provided in the middle of the sliding placement tube 433. A detection component 6 is mounted on one side of the upper part of the workbench 1. The ring-shaped frame 41 is fixed to the upper middle of the movable platform 2, and a linkage component 42 is provided in the middle and above the ring-shaped frame 41. The linkage component 42 includes a drive motor 421. Mounted at the upper center of the ring frame 41, the output end of the drive motor 421 is connected to a rotating rod 422, and three gear sleeves 423 are distributed around the rotating rod 422. Rack guide blocks 424 are symmetrically meshed on different sides of the three gear sleeves 423. Support guide frames 425 are distributed around the upper periphery of the movable platform 2. The bottom ends of multiple rack guide blocks 424 are provided with meshing teeth 426, and a gear disc 427 meshes below the meshing teeth 426. The support guide frame 425 is movably connected to the corresponding rack guide block 424. An adjustment assembly 43 is installed in the middle of multiple placement racks 3, and the adjustment assembly 43 includes positive and negative lead screws 431. Furthermore, the positive and negative lead screws 431 are installed on one side of the middle of the placement frame 3. Lead screw sleeves 432 are screwed onto both sides of the middle of the positive and negative lead screws 431, and sliding placement tubes 433 are fixed inside a pair of lead screw sleeves 432. A sliding groove 434 is opened on one side of the interior of the placement frame 3. The sliding groove 434 and the sliding placement tubes 433 are horizontally and movably connected. Workers can adjust the spacing of each pair of sliding placement tubes 433 in multiple placement frames 3 in advance according to the pin spacing of inductors in the same batch. The specific adjustment method is as follows: the worker starts the drive motor 421, causing the rotating rod 422 and the three gear sleeves 423 distributed around it to rotate synchronously. At this time, the gear sleeves 422... 3. The rack guide blocks 424 on opposite sides of different orientations and meshing with it will move relative to each other in coordination with the guide frame 425. Since the bottom part of the end of each rack guide block 424 is provided with meshing teeth 426, and the meshing tooth surface of the meshing teeth 426 meshes with a toothed disc 427, the toothed disc 427 will rotate with the meshing action and drive the corresponding positive and negative lead screws 431 to rotate. In this state, each pair of lead screw sleeves 432 that cooperate with the positive and negative lead screws 431 will carry the sliding placement tubes 433 that are fixed to them, and move relative to each other in coordination with the guide of the sliding groove 434, thereby achieving the purpose of synchronously adjusting the spacing of multiple pairs of sliding placement tubes 433 in multiple placement frames 3.

[0020] The limiting mechanism 5 includes a female guide block 51, which is disposed around the middle periphery of the sliding placement tube 433. A spring 52 is installed inside the female guide block 51, and a male guide block 53 is connected to the end of the spring 52. An arc-shaped limiting block 54 is connected to the end of the male guide block 53. A baffle plate 55 is fixed to the top of the inside of the female guide block 51. The arc-shaped limiting block 54 forms an elastic guide connection with the male guide block 51, the spring 52, and the male guide block 53. Personnel can insert the inductor pins into the middle of a pair of sliding placement tubes 433 within the placement rack 3. Since three sets of limiting mechanisms are provided inside the sliding placement tube 433... Mechanism 5, in which three arc-shaped limiting blocks 54, under the sliding guidance of the mother guide block 51 and the child guide block 53, and the elastic support of the spring 52, form a stable clamp for the inductor pins. After clamping, the inductor can be tested by a pair of detection plates in the detection assembly 6 in conjunction with the cylinder drive. It is worth mentioning that a servo motor is installed under the worktable 1 to drive the movement of the movable table 2. This motor can realize the cyclic detection of multiple sets of inductors on the movable table 2. During the detection process, the personnel can also perform material loading operations simultaneously, thereby improving the detection efficiency of the inductor.

[0021] It should be noted that, compared to the detection section in the comparative document, detection component 6 only adds an electric push rod and a limit guide rod in terms of component composition. These two new components are mainly used to intermittently provide travel space for the rack guide block 424. Apart from the above-mentioned new components, the other components of detection component 6 and their functions are consistent with the detection section in the comparative document. For relevant details, please refer to the comparative document, and we will not elaborate further here.

[0022] Working principle: Operators can pre-adjust the spacing of each pair of sliding placement tubes 433 within multiple placement racks 3 according to the pin spacing of inductors in the same batch. Specifically, the operator starts the drive motor 421, causing the rotating rod 422 and its three surrounding gear sleeves 423 to rotate synchronously. At this time, the rack guide blocks 424, located on opposite sides of the three gear sleeves 423 and meshing with them, will move relative to each other in coordination with the guide frame 425. Since each rack guide block 424 has meshing teeth 426 at its end, and the meshing surfaces of the meshing teeth 426 mesh with a gear disc 427, the gear disc 427 will rotate with the meshing action, driving the corresponding positive and negative lead screws 431 to rotate. In this state, each pair of lead screw sleeves 432 that meshes with the positive and negative lead screws 431 will carry the corresponding fixed sliding placement tubes 433, cooperating with the guide of the sliding groove 434. The relative displacement is achieved to synchronously adjust the spacing between multiple pairs of sliding placement tubes 433 within multiple placement racks 3. Then, personnel can insert the inductor pins into the middle of a pair of sliding placement tubes 433 within the placement rack 3. Since the sliding placement tubes 433 are equipped with three sets of limiting mechanisms 5, the three arc-shaped limiting blocks 54, under the sliding guidance of the mother guide block 51 and the child guide block 53, and the elastic support of the spring 52, form a stable clamp on the inductor pins. After clamping, the inductor can be tested simply by using a pair of detection plates in the detection assembly 6 in conjunction with a cylinder drive. It is worth mentioning that a servo motor driving the movable platform 2 is installed below the workbench 1. This motor can achieve cyclic testing of multiple sets of inductors on the movable platform 2, and during the testing process, personnel can simultaneously perform loading operations, thereby improving the efficiency of inductor testing.

[0023] All technical features in this embodiment can be freely combined according to actual needs.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
