Description

Technical Field

[0001] This utility model relates to the field of inductor assembly technology, and in particular to an integrated inductor assembly fixture. Background Technology

[0002] With continuous technological advancements and rising market demands, modern electronic devices are placing increasingly higher requirements on power management, especially in high-efficiency, high-power uninterruptible power supplies (UPS) and inverters. Inductors, as a core component, not only perform filtering, energy storage, and current stabilization functions, but also require high-frequency response, low loss, and high reliability. To meet market demands and enhance competitiveness, the design and cost requirements for inductors are also increasing. As the size of inductors increases, the size of the magnetic core also increases accordingly. However, manufacturing a single, large-volume magnetic core is extremely expensive. Therefore, current technologies typically employ a splicing method, combining multiple relatively smaller blocks to form a larger magnetic core. This spliced ​​magnetic core is commonly referred to as an integrated inductor. This splicing method not only reduces the manufacturing cost of a single large-volume magnetic core but also allows for more flexible control over the core's size and shape during production.

[0003] Despite the numerous advantages of integrated inductor design, several technical challenges remain in actual production. The fabrication process typically involves assembling a semi-finished inductor from upper and lower yoke ferromagnetic cores, a central core, and a coil. Multiple semi-finished inductors are then arranged and assembled with several side cores to obtain the final integrated inductor. However, both assembly processes require applying adhesive to the joints of the cores and baking for curing. Current technology often uses a fixture to assemble the components of the semi-finished inductor, followed by baking and curing, and then another fixture to assemble the semi-finished inductor with the side cores. Inductance adjustments are necessary during both assemblies based on actual requirements. If the inductance fails to meet specifications during the second assembly, the semi-finished inductor risks being scrapped. Furthermore, the assembly process is overly cumbersome and inefficient. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides an integrated inductor assembly fixture, comprising:

[0005] Fastening mechanism for loading semi-finished inductors;

[0006] An assembly mechanism is provided with multiple slots for loading the side magnetic core, and the fastening mechanism is detachably installed between two adjacent slots.

[0007] Preferably, the fastening mechanism includes a first base plate, and a first baffle is provided at each of the two ends of the first base plate, wherein a first adjustment component is provided through one of the first baffles;

[0008] The inductor semi-finished product is loaded between the end of the first adjustment component and another of the first baffles.

[0009] Preferably, the other first baffle has a first partition on the side facing the first adjustment assembly.

[0010] Preferably, at least one positioning through hole is provided on the first base plate.

[0011] Preferably, the positioning through hole is a strip-shaped hole.

[0012] Preferably, the assembly mechanism includes a second base plate, the second base plate is provided with a plurality of slots, and an assembly groove for installing the fastening mechanism is formed between two adjacent slots;

[0013] The second base plate has a second baffle at each end, and a second adjustment component is installed on one of the second baffles.

[0014] Preferably, another second baffle is provided on the side facing the second adjusting component.

[0015] Preferably, each of the assembly slots in the second base plate is provided with at least one positioning post.

[0016] Preferably, one side of the second base plate is provided with a side plate, and the two ends of the side plate abut against the two second baffles respectively.

[0017] Preferably, the second adjusting component has a third partition at one end facing the other second baffle.

[0018] The above technical solution has the following advantages or beneficial effects:

[0019] 1) By loading the inductor semi-finished products through the fastening mechanism, when multiple inductor semi-finished products and corresponding side magnetic cores need to be assembled, multiple fastening mechanisms can be installed on the assembly mechanism and the side magnetic cores can be loaded in the corresponding slots, thus realizing the one-time assembly of integrated inductors.

[0020] 2) Since multiple inductor semi-finished products are assembled with corresponding side magnetic cores, the air gap between each inductor semi-finished product and side magnetic core can be adjusted simultaneously according to the actual inductance requirements to achieve one-time inductance adjustment. The corresponding baking and curing process after inductance adjustment only needs to be performed once. Compared with the existing preparation method of "multiple inductance adjustments and multiple baking and curing", this greatly improves the preparation efficiency, reduces production energy consumption, and avoids the waste of raw materials caused by multiple adjustments, thus greatly reducing production costs.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment; other embodiments that conform to the spirit of the present invention may also fall within its scope.

[0027] In a preferred embodiment of this utility model, based on the above-mentioned problems existing in the prior art, an integrated inductor assembly fixture is provided, such as... Figures 1 to 4 As shown, it includes:

[0028] Fastening mechanism 1 is used to load the inductor semi-finished product 31;

[0029] Assembly mechanism 2 is provided with multiple slots 21 for loading side magnetic core 32, and fastening mechanism 1 is detachably installed between two adjacent slots 21.

[0030] Specifically, the integrated inductor is assembled by arranging and assembling multiple inductor semi-finished products 31 and several side magnetic cores 32. Each inductor semi-finished product 31 is assembled from multiple magnetic core components, each including an upper yoke core, a lower yoke core, a middle core core, and a coil. In this embodiment, the aforementioned magnetic core components of the inductor semi-finished product 31 are assembled and fixed by a fastening mechanism 1. Then, according to actual needs, a corresponding number of fastening mechanisms 1 containing the inductor semi-finished products 31 are selected and installed into the assembly mechanism 2. The assembly mechanism 2 has accommodating space between two adjacent slots 21 for installing the fastening mechanisms 1. After the fastening mechanisms 1 containing the inductor semi-finished products 31 are installed into the assembly mechanism 2, a set number of side magnetic cores 32 are placed into the slots 21 on the sides of each inductor semi-finished product 31, thus assembling the desired integrated inductor semi-finished product 31. During assembly, insulating adhesive is applied to the joints of each magnetic core component, and after inductance adjustment, the inductance is baked and cured to obtain the final integrated inductor.

[0031] In a preferred embodiment of the present invention, the fastening mechanism 1 includes a first base plate 11, and a first baffle 12 is provided at both ends of the first base plate 11, and a first adjusting component 13 is provided on one of the first baffles 12.

[0032] The inductor semi-finished product 31 is installed between the end of the first adjustment component 13 and another first baffle 12.

[0033] In a preferred embodiment of the present invention, a first partition 14 is provided on the side of another first baffle 12 facing the first adjusting component 13.

[0034] Specifically, in this embodiment, the upper yoke core and the lower yoke core of the inductor semi-finished product 31 are respectively disposed at both ends of the central column core on which the coil is sleeved. During assembly, the upper yoke core and the lower yoke core are respectively placed facing the two first baffles 12. The upper and lower yoke cores respectively abut against one end of the first partition 14 and the first adjustment component 13. One side of the inductor semi-finished product 31 is attached to the first base plate 11, thereby fixing the inductor semi-finished product 31 to the fastening mechanism 1.

[0035] The first partition 14 is made of a flexible material, such as epoxy board, to reduce damage to the magnetic core caused by the metal first baffle 12; the first adjustment component 13 can be, for example, Figures 1 to 3 The spiral assembly shown has an external thread on its main body and a through hole on the corresponding first baffle 12. The inner wall of the through hole has an internal thread. The threaded connection enables the adjustment of the distance between the end of the first adjusting assembly 13 and the first baffle 12 on the opposite side, thereby enabling the physical pressing and tightness adjustment of the areas where insulating glue is applied to each magnetic core assembly in the inductor semi-finished product 31.

[0036] Preferably, the side of the first adjustment component 13 closest to the magnetic core has a large cross-section, or it can be made of a flexible material similar to the first partition 14 to reduce damage to the magnetic core during screw adjustment.

[0037] In a preferred embodiment of the present invention, the assembly mechanism 2 includes a second base plate 22, on which a plurality of slots 21 are provided, and an assembly groove 23 for installing the fastening mechanism 1 is formed between two adjacent slots 21.

[0038] The second base plate 22 is provided with a second baffle 24 at both ends, and a second adjustment component 25 is provided on one of the second baffles 24.

[0039] Specifically, in this embodiment, multiple assembly slots 23 can be provided according to actual needs. Taking the integrated inductor as a three-phase structure as an example, there are 3 sets of inductor semi-finished products 31, and the corresponding number of assembly slots 23 is 3. The 3 fastening mechanisms 1 with inductor semi-finished products 31 can be installed into the 3 assembly slots 23 in sequence. Each assembly slot 23 has a slot 21 on both sides, and adjacent assembly slots 23 share a slot 21. That is, there are a total of 4 slots 21 in this embodiment. The slots 21 are used to place the side magnetic cores 32 of the integrated inductor. The size of the slot 21 matches the size of the side magnetic core 32. When the side magnetic core 32 is inserted into the slot 21, it just abuts against the side of the adjacent inductor semi-finished product 31. The 4 side magnetic cores 32 and the 3 inductor semi-finished products 31 together form the three-phase integrated inductor semi-finished product in this embodiment.

[0040] Furthermore, two second baffles 24 are provided on both sides of the second base plate 22. The two second baffles 24 are respectively provided with second partitions 26 and second adjustment components 25. The two side magnetic cores 32 at both ends of the above-mentioned three-phase integrated inductor semi-finished product abut against the second partitions 26 and the second adjustment components 25 respectively, so as to realize the assembly and fixation of the entire three-phase integrated inductor semi-finished product.

[0041] The second partition 26 is made of a flexible material, such as epoxy board, to reduce damage to the magnetic core from the metal baffle; the second adjustment component 25 can be, for example, Figures 1 to 3 The spiral assembly shown has an external thread on its main body and a through hole on the corresponding second baffle 24. The inner wall of the through hole has an internal thread. The threaded connection allows for adjustment of the distance between the end of the second adjustment assembly 25 and the second baffle 24 on the opposite side. This enables physical compression of the areas where insulating adhesive is applied to each magnetic core assembly in the inductor semi-finished product 31. At the same time, the preset inductance is adjusted by the tightness (i.e., the air gap size) to ensure that the shape and inductance of the molded inductor after baking and curing are consistent with the preset value.

[0042] In a preferred embodiment of the present invention, at least one positioning through hole 15 is provided on the first base plate 11.

[0043] In a preferred embodiment of the present invention, at least one positioning post 27 is provided at the location of each assembly slot 23 of the second base plate 22.

[0044] Specifically, in this embodiment, the positioning post 27 corresponds to the positioning through hole 15. When the fastening mechanism 1 is installed, the positioning post 27 passes through the positioning through hole 15 to limit the position of the fastening mechanism 1.

[0045] Further preferably, the positioning through hole 15 is a strip hole.

[0046] Specifically, in this embodiment, the first base plate 11 is provided with strip-shaped positioning through holes 15. Multiple positioning through holes 15 can be provided to ensure the stability of the fastening mechanism 1 when it is installed into the assembly mechanism 2, preventing it from displacing in a direction perpendicular to the movement of the second adjustment component 25. The assembly groove 23 of the second base plate 22 is provided with positioning posts 27 that match the positioning through holes 15. In this embodiment, the positioning posts 27 are cylindrical, and the height of the positioning posts 27 is not greater than the height of the positioning through holes 15. The diameter of the positioning posts 27 is the same as the width of the positioning through holes 15 but less than the length of the positioning through holes 15, so that the fastening mechanism 1 can be driven by the second adjustment component 25 to make relative displacement with the assembly mechanism 2, thereby adjusting the tightness between the inductor semi-finished product 31 and the side magnetic core 32.

[0047] In a preferred embodiment of the present invention, a side plate 28 is provided on one side of the second base plate 22, and the two ends of the side plate 28 abut against the two second baffles 24 respectively.

[0048] Specifically, the side plate 28 is located on the side of the second base plate 22 that is different from the two second partition plates 26. This arrangement can improve the overall strength of the assembly mechanism 2 and prevent deformation under long-term stress and high-temperature baking conditions. The fastening mechanism 1 is installed from the side of the second base plate 22 away from the side plate 28.

[0049] In a preferred embodiment of the present invention, a third partition 29 is provided at the end of the second adjusting component 25 facing the other second baffle 24.

[0050] Specifically, in this embodiment, after the side magnetic core 32 and the inductor semi-finished product 31 are sequentially installed on the assembly mechanism 2, a third partition 29 is placed on the side magnetic core 32 near the second adjustment component 25 to separate the side magnetic core 32 from the second adjustment component 25, so as to avoid damage to the side magnetic core 32 when rotating the second adjustment component 25.

[0051] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made using the content of this specification and illustrations should be included within the protection scope of the present utility model.
