[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. The various technical features in the utility model can be combined interchangeably without conflicting with each other.

[0032] First, refer to Figures 1 to 4The embodiment of the utility model proposes a U-shaped inductor assembly jig, which can assist in assembling the inductor bracket 400 and the iron core 500, ensuring that the air gap 510 spacing of the inductor iron core 500 of the same batch is the same, thereby ensuring the quality and performance of the same batch of products and improving the inductor production efficiency.

[0033] In this embodiment, the U-shaped inductor assembly jig includes a base and a baffle 300. The base is used to support the bracket 400 and the core 500 of the inductor, and can fix the core 500 to ensure that the air gap 510 of the core 500 has the same spacing. The base includes a base body 100 and a boss structure 200. When in use, the base body 100 is horizontally arranged, and the boss structure 200 is connected to the upper surface of the base body 100 and is arranged in the middle of the base body 100. A plurality of nut holes 110 are arranged on the base body 100, and the nut holes 110 match the shape of the nut 800, and the plurality of nut holes 110 are respectively arranged on the outer side of the boss structure 200. The baffle 300 includes a front baffle surface 310 and a side baffle surface 320, and two side baffle surfaces 320 are arranged, and the two side baffle surfaces 320 are respectively connected to the left end and the right end of the front baffle surface. The front blocking surface 310 is connected to the front end surface of the base body 100 , and the two side blocking surfaces 320 are connected to the left end surface and the right end surface of the base body 100 respectively.

[0034] It can be understood that the inductor is assembled by assembling the bracket 400 and the iron core 500 together, wherein two brackets 400 are provided, and the two brackets 400 are respectively provided on the upper side and the lower side of the iron core 500, that is, the two brackets 400 clamp the core together. When using the U-shaped inductor assembly jig auxiliary device inductor of this embodiment, first set the nut 800 in the nut hole 110, and then stack the bracket 400, the iron core 500 and the bracket 400 on the top of the seat 100 in sequence, and finally pass the screw 600 through the upper bracket 400, the iron core 500 and the lower bracket 400, and connect the lower end of the screw 600 with the nut 800 through threaded cooperation, so that the bracket 400-iron core 500-bracket 400 combination forms an inductor.

[0035] In this embodiment, the baffle 300 is extended upward and protrudes upward from the upper surface of the base 100. When placing the bracket 400 on the base 100, the front end of the bracket 400 is abutted against the front baffle surface 310 of the baffle 300, the left end of the bracket 400 is abutted against the side baffle surface 320 on the left side of the baffle 300, and the right end of the bracket 400 is abutted against the side baffle surface 320 on the right side of the baffle 300, so that the two brackets 400 can be limited to specific positions of the base 100, and the worker does not need to spend more time aligning the relative positions of the two brackets 400.

[0036] It is understandable that the front end face and the left and right end faces of the bracket 400 are respectively perpendicular. Correspondingly, the front baffle surface 310 and the side baffle surfaces 320 of the baffle 300 are also perpendicular to each other, and the front baffle surface 310 and the two side baffle surfaces 320 respectively form two right-angle structures.

[0037] This embodiment is applied to the assembly of a U-shaped inductor. It can be understood that a through-hole structure is provided in the middle of the bracket 400 of the U-shaped inductor. When the bracket 400 is set on the base 100, the boss structure 200 is located in the through-hole structure, and the setting of the boss structure 200 will not interfere with the placement of the bracket 400.

[0038] The iron core 500 of the U-shaped inductor is composed of two U-shaped core bodies. When in use, the two U-shaped core bodies of the iron core 500 are respectively clamped on the left and right sides of the boss structure 200. The openings of the two U-shaped core bodies are arranged opposite to each other and form a cavity together. The boss structure 200 is located in the cavity, and the rear end surface of the cavity abuts against the rear end surface of the boss structure 200. Under the restriction of the boss structure 200, the positions of the two core bodies on the base 100 are determined.

[0039] It is understandable that there is a certain gap between the two U-shaped cores, which is the air gap 510 of the iron core 500. Due to the limiting effect of the boss structure 200, the width of the gap between the two U-shaped cores is guaranteed to be the same as the preset width of the air gap 510, thereby ensuring that the assembled inductor achieves the preset performance. Figure 5 shown.

[0040] In this embodiment, the nut 800 is a countersunk hole. The nut 800 used to cooperate with the screw 600 and lock the inductor formed by the bracket 400-iron core 500-bracket 400 combination can be completely placed in the nut hole 110 and will not fall off downwards. The bracket 400 can be placed flat on the upper surface of the base 100, and the operator does not need to support the nut 800 by hand.

[0041] In this embodiment, a hexagonal nut 800 is used, and the matching nut hole 110 is a hexagonal hole. The nut hole 110 can limit the nut 800. After the screw 600 is inserted into the screw hole of the nut 800, during the rotation of the screw 600, the nut 800 does not rotate with the rotation of the screw 600 under the limiting effect of the nut hole 110, so that the relative position between the lower end surface of the screw 600 and the nut 800 can be changed. After the screw 600 is screwed into the nut 800, the lower end of the screw 600 abuts against the lower end surface of the nut hole 110. If the screw 600 is continuously rotated, the nut 800 will move upward along the extension direction of the screw 600 until the upper end surface of the nut 800 abuts against the lower surface of the bracket 400. At this time, the nut 800 and the screw 600 jointly lock the inductance formed by the bracket 400-iron core 500-bracket 400 combination.

[0042] In some embodiments, the seat body 100 is further provided with a flat washer groove 120, which is opened upward and communicates with the nut hole 110. There are a plurality of flat washer grooves 120, and the plurality of flat washer grooves 120 are respectively provided in one-to-one correspondence with the plurality of nut holes 110, and the corresponding flat washer grooves 120 and the nut holes 110 are coaxially arranged, and the flat washer grooves 120 are located on the upper side of the nut holes 110.

[0043] It can be understood that the flat washer groove 120 is used to place the flat washer 700, and a through hole is provided in the middle of the flat washer 700. During assembly, the screw 600 passes through the bracket 400, the iron core 500, and the bracket 400 located at the lower side in sequence, and then passes through the through hole of the flat washer 700 and then into the screw hole of the nut 800. In the assembled inductor, the bottom surface of the bracket 400 located at the lower side and the nut 800 are separated by the flat washer 700. The provision of the flat washer 700 can increase the contact area between the nut 800 and the bracket 400, has a certain protective effect on the nut 800 and the bracket 400, reduces the scrap rate of the nut 800 and the bracket 400 during the assembly process, and can also increase the service life of the assembled inductor.

[0044] It is understandable that after tightening the screw 600, the screw head 600 of the screw 600 abuts against the upper surface of the upper bracket 400. In some embodiments, a flat washer 700 is also provided between the screw head 600 and the upper surface of the upper bracket 400. The flat washer 700 increases the contact area between the screw head 600 and the bracket 400, which has a certain protective effect on the screw 600 and the bracket 400, reduces the scrap rate of the screw 600 and the bracket 400 during the assembly process, increases the service life of the assembled inductor, and can also make the locking of the screw 600 more stable.

[0045] It is understandable that a flat washer 700 is provided between the head of the screw 600 and the bracket 400 located on the upper side. When installing the screw 600, the screw 600 first passes through the flat washer 700 located above the upper bracket 400, and then passes through the upper bracket 400, the iron core 500, the lower bracket 400, the flat washer 700 below the lower bracket 400 and the nut 800 in sequence.

[0046] In this embodiment, four nut holes 110 are provided, and the four nut holes 110 are respectively provided at the four corners of the base body 100. Correspondingly, four screws 600 and nuts 800 are respectively provided for connecting the bracket 400 and the iron core 500, and the four corners of the bracket 400 and the iron core 500 can be locked. In this way, the bracket 400 and the iron core 500 can be stably connected with less parts, and the force is evenly applied, so as to obtain an inductor with stable quality.

[0047] In some embodiments, the upper end surface of the baffle 300 is higher than the upper end surface of the boss structure 200. The height of the boss structure 200 is higher than or equal to the sum of the heights of the lower bracket 400 and the iron core 500, which can effectively limit the position of the iron core 500, and the baffle 300 needs to limit the lower bracket 400 and the upper bracket 400, so the upper end surface of the baffle 300 needs to be higher than the upper surface of the upper bracket 400 of the assembled inductor to effectively limit the two brackets 400.

[0048] It is understandable that the height of the boss structure 200 may be higher than or equal to the height of the upper end surface of the baffle 300, but the portion of the boss structure 200 that is higher than the upper end of the iron core 500 of the assembled inductor has no limiting effect on the iron core 500. In this embodiment, the upper end surface of the baffle 300 is designed to be higher than the upper end surface of the boss structure 200, which can effectively limit the iron core 500 and the bracket 400 while reducing the waste of the material of the boss structure 200 that exceeds the upper end surface of the iron core 500, and can reduce the weight of the entire U-shaped inductor assembly jig.

[0049] In some embodiments, a weight reduction opening 330 is provided at the front baffle surface 310 of the baffle plate 300, and the weight reduction opening 330 runs through the upper wall and the lower wall of the front baffle surface 310, and divides the front baffle surface 310 into two left and right sections, wherein the left end of the front baffle surface 310 section on the left side of the weight reduction opening 330 is connected to the side baffle surface 320 on the left side, and the right end of the front baffle surface 310 section on the right side of the weight reduction opening 330 is connected to the side baffle surface 320 on the right side.

[0050] It is understandable that such a configuration can reduce the materials used in manufacturing the baffle 300, reduce the cost, and reduce the weight of the entire U-shaped inductor assembly fixture, making it more lightweight.

[0051] It is understandable that the baffle 300 and the base 100 can be connected and fixed by gluing, welding, screws 600, etc., which are not specifically limited here. In this embodiment, the lower end surface of the baffle 300 is flush with the lower end surface of the base 100. Such a setting can increase the connection area between the baffle 300 and the base 100, thereby improving the connection strength, allowing the baffle 300 to maintain contact with the edge of the base 100, ensuring the verticality between the baffle 300 and the upper surface of the base 100, and thus ensuring the accuracy of the installation position of the bracket 400.

[0052] It is understandable that the air gap 510 can avoid magnetic saturation under large AC signals or DC bias, and better control the inductance. The air gap 510 of the iron core 500 will not affect the original characteristics of the iron core 500, and can increase the working magnetic flux density and saturation magnetic flux density. Secondly, the air gap 510 of the iron core 500 is mainly to reduce the residual magnetism of the iron core 500 when it works in an asymmetric magnetic field state. Generally, the larger the air gap 510, the smaller the residual magnetism of the iron core 500 when the coil current drops to zero, so that the iron core 500 of the same volume can output greater power. However, the larger the air gap 510, the smaller the inductance coefficient of the iron core 500. In order to achieve a certain inductance, more coils need to be wound, and the related copper loss will also increase. The number of coil turns increases, and the distributed capacitance also increases relatively, which may affect the working stability of the electromagnetic component. Therefore, in actual application, it is necessary to weigh many aspects to determine the preferred value of the size of the air gap 510 of the iron core 500.

[0053] In some embodiments, the boss structure 200 is detachably connected to the upper surface of the base 100. By disassembling the boss structure 200, boss structures 200 of different specifications and types can be replaced, so as to be suitable for producing and assembling inductors with different air gap 510 requirements.

[0054] When it is necessary to assemble an inductor with a larger air gap 510 width, a boss structure 200 with a larger left and right width can be selected. When the iron core 500 is installed, the air gap 510 formed between the two U-shaped core bodies will be increased; and when it is necessary to assemble an inductor with a smaller air gap 510 width, a boss structure 200 with a smaller left and right width can be selected and installed on the base body 100. When the iron core 500 is installed, the air gap 510 formed between the two U-shaped core bodies will be reduced.

[0055] In some embodiments, the upper surface of the base 100 is provided with a slot opening upward, and the bottom surface of the boss structure 200 is provided with a protrusion protruding downward, the protrusion and the slot are matched with each other, and the protrusion is engaged in the slot when the base 100 and the boss structure 200 are connected. It can be understood that under the restriction of the slot, the four sides of the protrusion are locked, and the boss structure 200 cannot move to the left, right, front, and back relative to the base 100, thereby ensuring the accuracy of the position of the iron core 500.

[0056] It is understandable that the detachable connection between the seat body 100 and the boss structure 200 can be achieved through the matching connection between the protrusion and the slot. Moreover, the boss structure 200 and the seat body 100 are relatively simple to process, and the disassembly and assembly are also very convenient and quick.

[0057] In some embodiments, the base body 100 is provided with a curved surface structure 130, which is provided at the rear end of the base body 100 and is used to connect and transition the upper end face and the rear end face of the base body 100. It can be understood that the provision of the curved surface structure 130 can prevent the sharp corner formed between the upper end face and the rear end face of the base body 100 from causing harm to the operator, and can also prevent the sharp corner from cutting the bracket 400 provided on the base body 100, thereby playing a certain protective role for the various assembled components of the inductor.

[0058] In the second aspect, the embodiment of the utility model further proposes a U-shaped inductor automatic assembly machine, which includes the U-shaped inductor assembly jig proposed in any one of the embodiments of the first aspect above. The U-shaped inductor automatic assembly machine can insert the nut 800, the flat washer 700, the bracket 400, the iron core 500 and other components into the U-shaped inductor assembly jig through automated equipment such as a manipulator, and automatically tighten the screw 600 to realize the automatic assembly of the U-shaped inductor, greatly reducing the labor intensity of the workers.

[0059] It is understandable that the provision of the U-shaped inductor assembly jig makes the automatic assembly of the inductor more accurate, provides a reference for the actions of automated equipment such as robots, and ensures that the core 500 and air gap 510 spacing of the same batch of inductors are the same, thereby ensuring the quality and performance of the product.

[0060] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
