Description

Technical Field

[0001] This utility model relates to the field of magnetic core testing technology, specifically to an automatic magnetic core appearance testing device. Background Technology

[0002] A magnetic core is a core component made of magnetic materials, commonly used in electromagnetic elements such as inductors and transformers. Its main function is to enhance and guide the magnetic field, thereby improving the efficiency and performance of electromagnetic devices. The performance of the magnetic core directly affects the efficiency, size, and reliability of electromagnetic components. Choosing appropriate magnetic core materials and shapes can optimize circuit design and meet different application requirements.

[0003] However, before the magnetic core leaves the factory, it needs to be visually inspected to ensure that the appearance of the magnetic core is intact. However, due to the traditional magnetic core inspection, it is time-consuming to manually handle and compare it repeatedly. At the same time, the magnetic core is prone to falling when handled manually, which can damage the magnetic core. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an automatic magnetic core appearance inspection device, which can conveniently inspect the appearance of the magnetic core around its perimeter when the magnetic core is placed relatively stably, thereby reducing the risk of damage to the magnetic core caused by holding it. At the same time, it can automatically control the angle of observation of the back and sides of the magnetic core, improving the detail of the magnetic core inspection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic magnetic core appearance inspection device, comprising a base, a top plate, and a drive motor. The top inner side of the base is provided with a first sliding groove, and a sliding seat is slidably engaged inside the first sliding groove. Two sets of fixing rods are fixed to the top of the sliding seat, and mirrors are fixed to the front surfaces of the two sets of fixing rods. A connecting plate is fixed to the top of the two sets of fixing rods, and a first connecting post is fixed to the top of the connecting plate. A limit block is fixed to the top of the first connecting post.

[0006] By adopting the above technical solution, the first slide groove is used to limit the sliding seat to slide inside the base. The sliding seat is used to drive the upper parts to move synchronously. The fixing rod can fix the mirror stably on the sliding seat. The mirror can conveniently observe the appearance of the back and side of the magnetic core. The connecting plate is used to stabilize and limit the top of the two sets of fixing rods. The first connecting column and the limiting block are used to connect with the driving parts, thereby driving the lower parts to move automatically.

[0007] Furthermore, a placement platform is fixed at the top center of the base, and a support frame is fixed at the top of the base outside the first slide groove.

[0008] By adopting the above technical solution, the placement platform is fixed at the top center of the base, providing an independent and stable bearing area for the magnetic core, and the support frame is used to provide support for the top plate.

[0009] Furthermore, a top plate is fixed to the top of the support frame, and a drive motor is provided at the center of the top of the top plate.

[0010] By adopting the above technical solution, the top plate can provide stability for the installation of the drive motor, while the drive motor can provide a driving source for the adjustment plate.

[0011] Furthermore, a second sliding groove is provided on the inner side of the top plate and on the outer side of the drive motor for the limiting block to engage and slide, and the second sliding groove is configured in a semi-circular shape.

[0012] By adopting the above technical solution, the second slide groove is used to provide sliding space for the limiting block, and the semi-circular structure of the second slide groove is used to limit the sliding space of the limiting block.

[0013] Furthermore, the drive motor is electrically connected to an external power source through the control center, and an adjustment plate is provided at the output end of the drive motor.

[0014] By adopting the above technical solution, the drive motor is electrically connected to the external power supply through the control center. This design allows the start, stop and speed of the drive motor to be easily controlled by the control center, and the adjustment plate can drive the second connecting column to move synchronously.

[0015] Furthermore, a second connecting post is fixed to the bottom of one end of the adjusting plate and is fixedly connected to the top of the limiting block.

[0016] By adopting the above technical solution, the second connecting column is fixedly connected to the top of the limiting block, thereby driving the limiting block to slide automatically in the second slide groove.

[0017] In summary, the present invention has the following main advantages:

[0018] This invention, by setting up a first sliding groove, a sliding seat, a fixed rod, and a mirror, allows the adjustment plate to slide when the drive motor rotates. The adjustment plate, via a second connecting post at one end, drives a bottom limiting block to slide within the second sliding groove at the top of the top plate. Simultaneously, the second sliding groove provides a sliding limit for the limiting block. Furthermore, the limiting block, via the first connecting post at the bottom, drives a connecting plate to slide, allowing the connecting plate to synchronously slide with the fixed rod and sliding seat, which form an integrated mechanism. The sliding seat is limited by the first sliding groove on the inner side of the base, thus providing stability to the mirror during its movement. This allows the mirror to reflect the back and sides of the magnetic core placed on the top of the platform, enabling inspectors to better inspect the appearance of the magnetic core.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0025] In this embodiment:

[0026] An automatic inspection device for the appearance of magnetic cores, such as Figures 1-4 As shown, it includes a base 1, a top plate 4 and a drive motor 5. The top inner side of the base 1 is provided with a first sliding groove 6, and a sliding seat 7 is slidably engaged inside the first sliding groove 6. Two sets of fixing rods 8 are fixed to the top of the sliding seat 7, and a mirror 10 is fixed to the front surface of the two sets of fixing rods 8. A connecting plate 9 is fixed to the top of the two sets of fixing rods 8, and a first connecting post 11 is fixed to the top of the connecting plate 9. A limit block 13 is fixed to the top of the first connecting post 11.

[0027] The sliding seat 7 is stably limited and slids within the first sliding groove 6, allowing the mirror 10 to move smoothly along a preset path. The limiting block 13 is slidably limited by the second sliding groove 12 of the top plate 4, and is rigidly linked to the sliding seat 7 with the connecting plate 9 through the first connecting column 11. This ensures that the movement trajectory of the mirror 10 is mechanically constrained by both sliding grooves, guaranteeing the synchronicity of the mirror 10's movement process and eliminating the risk of single-point failure through double limiting. This further improves the stability of the mirror 10 during movement, ensuring the continuity and accuracy of the reflections from the back and sides of the magnetic core, and significantly reducing the subjective error and missed detection probability of manual inspection.

[0028] See Figure 1 , Figure 2 and Figure 3 The base 1 has a placement platform 2 fixed at the top center, and a support frame 3 is fixed at the top of the base 1 and outside the first slide groove 6.

[0029] The placement platform 2 provides a precise positioning reference surface for the magnetic core, ensuring that the center of the magnetic core is strictly aligned with the reflection path of the mirror 10. The top of the base 1 and the outer side of the first slide groove 6 are fixed with a support frame 3, which ensures good stability of the top plate 4 and its top components during operation.

[0030] See Figure 1 and Figure 2 The top of the support frame 3 is fixed with a top plate 4, and a drive motor 5 is provided at the center of the top of the top plate 4.

[0031] Among them, the top plate 4 provides a mounting base for the drive motor 5 through a rigid support structure. The drive motor 5 accurately outputs rotational power to the adjustment plate 15 through a centralized layout, realizing the mechanical decoupling and functional integration of the transmission system and the load-bearing system.

[0032] See Figure 1 , Figure 2 and Figure 3 The top plate 4 has a second sliding groove 12 on its inner side and outside the drive motor 5 for the limiting block 13 to engage and slide, and the second sliding groove 12 is set in a semi-circular structure.

[0033] The second slide 12, through its semi-circular cross-section channel design, provides a linear sliding path for the limiting block 13 while constraining the radial offset of the limiting block 13 with its arc-shaped groove wall, thus achieving the dual functions of sliding guidance and spatial limitation.

[0034] See Figure 1 and Figure 2 The drive motor 5 is electrically connected to an external power source through the control center, and an adjustment plate 15 is provided at the output end of the drive motor 5.

[0035] The operator can precisely adjust the operating status of the drive motor 5 through the control center according to the actual rotation angle requirements, and the adjustment plate 15 can better transmit the power of the drive motor 5 to the second connecting column 14.

[0036] See Figure 1 and Figure 2 The bottom of one end of the adjusting plate 15 is fixed with a second connecting post 14 and is fixedly connected to the top of the limiting block 13;

[0037] The bottom of one end of the adjusting plate 15 is fixed with a second connecting column 14, so that the second connecting column 14 can receive the power of the drive motor 5 through the adjusting plate 15, and thus completely transmit it to the limit block 13, thereby driving the components at the bottom of the limit block 13 to move synchronously.

[0038] The implementation principle of this embodiment is as follows: First, the base 1 is stably placed in the designated position. Then, the magnetic core to be tested is placed on the top of the placement platform 2. The drive motor 5 is then turned on through the control center, allowing the drive motor 5 to drive the second connecting column 14 to rotate via the adjusting plate 15. The adjusting plate 15 will drive the bottom limiting block 13 to slide within the second sliding groove 12 opened at the top of the top plate 4 via the second connecting column 14 at one end. Then, the second sliding groove 12 will provide sliding limit for the limiting block 13. In addition, the limiting block 13 will be driven by the first connecting column 11 at the bottom. The movable connecting plate 9 slides so that the fixed rod 8 and the sliding seat 7, which form an integrated mechanism with it, slide synchronously. Then, the sliding seat 7 slides in the first sliding groove 6 opened on the inner side of the base 1, so that the sliding seat 7 and the limiting block 13 provide stability during the movement of the mirror 10. This allows the mirror 10 to reflect the back and side of the magnetic core placed on the top of the placement platform 2, so that the inspector can better inspect the appearance of the magnetic core. Finally, after the appearance inspection of the magnetic core is completed, it can be removed from the top of the placement platform 2.
