[0001] The present application relates to the field of molded integrally formed inductors, and more specifically, to a method for manufacturing a molded integrally formed inductor and a manufacturing device thereof. Background Art

[0002] As high-speed, high-capacity 5G communication technology and third-generation semiconductor technologies such as GaN gradually become practical, electronic devices are accelerating towards miniaturization, high frequency, high integration, multi-function, and wearability. This also puts forward new requirements for electronic information materials. As soft magnetic materials and devices that are indispensable in the processes of electromagnetic transformation, transmission, and information emission, transmission, reception, processing, and recording, they face huge challenges of high frequency and low power consumption, and have become a key factor restricting the development of the next generation of electronic devices. Electronic terminal products are constantly developing in the direction of "miniaturization, integration, multi-function, and high power". Traditional plug-in inductors can no longer meet the needs of downstream electronic equipment, and new types of power inductors need to be developed.

[0003] The existing pressing equipment for molded inductors generally uses an upper mold after the mold is opened to cooperate with a lower mold for pressing. However, the pressing head of the existing upper mold generally does not have an adjustment function. Therefore, when molding inductors of different thicknesses, the pressing head needs to be replaced manually, which leads to problems such as difficulty in replacement and long replacement time, which greatly affects the efficiency of the equipment. Summary of the invention

[0004] The present invention solves the problem in the prior art that the pressure head of the upper mold generally does not have an adjustment function, so when molding inductors of different thicknesses, the pressure head needs to be replaced manually, which leads to the problem of great difficulty in replacement and long replacement time, which greatly affects the use efficiency of the equipment. To this end, the present invention proposes a manufacturing method and a manufacturing device for a molded integrally formed inductor, which can adjust the length of the pressure head without disassembling the pressure head.

[0015] A trapezoidal pressing block slidably connected in the upper die for pressing the pressing head, wherein the upper surface of each of the trapezoidal pressing blocks is equipped with a latching gear set;

[0016] A first dual-axis motor is fixed outside the upper mold, and first rotating rods are fixed on both output shafts of the first dual-axis motor, and a plurality of first gears meshing with the tooth groups on the upper surface of the trapezoidal pressing block are fixed on both the first rotating rods.

[0017] Preferably, the top of the pressure head is provided with an inclined groove matched with the inclined surface of the trapezoidal pressure block, and the inclined surface of the trapezoidal pressure block is slidably connected with the inclined groove at the top of the pressure head. By providing the inclined groove matched with the inclined surface of the trapezoidal pressure block at the top of the pressure head, the pressure direction of the trapezoidal pressure block will not be offset when applying pressure to the pressure head, and the friction loss between the trapezoidal pressure block and the pressure head is smaller.

[0018] Preferably, two groups of vibration components for increasing the pressing effect of the pressure head are symmetrically arranged in the upper mold, and the vibration components include a second double-axis motor and a second rotating rod.

The second double-axis motor is fixed on the top of the upper mold, and the two output shafts of the second double-axis motor are transmission-connected to the second rotating rod through an elastic transmission belt, and the second rotating rod is equipped with a plurality of elastic knocking blocks. When the second double-axis motor is working, the second rotating rod is controlled to rotate by the elastic transmission belt, and the plurality of elastic knocking blocks on the second rotating rod will knock the pressure head, thereby achieving the effect of vibration compaction. At the same time, since the position of the pressure head will change, the transmission of the second rotating rod and the second double-axis motor can be ensured by the setting of the elastic transmission belt.

[0019] Preferably, the elastic knocking blocks are arranged in a ring shape in groups of three on the second rotating rod, and every two groups of the elastic knocking blocks correspond to one pressing head. When the second rotating rod rotates, the elastic knocking blocks rotate and knock the top of the pressing head, thereby improving the molding effect through the vibration generated.

The U-shaped rod penetrates and is slidably connected to the top plate, and a gear group is provided at one end of the U-shaped rod close to the second gear and meshes with the second gear. When the upper mold assembly moves upward, the upper mold will squeeze the U-shaped rod.

The fourth rotating rod will drive the third rotating rod to rotate through the rubber transmission belt. When the third rotating rod rotates, the multiple annular vibration blocks fixed on its outside will continuously knock on the bottom of the connecting rod, and transmit the vibration to the top block through the connecting rod. The molded inductor is separated from the lower mold through the vibration on the top block, which is convenient for subsequent demolding operations.

[0021] Preferably, the annular vibration block is located below the connecting rod and is in a fitted state, and a gap is left between the U-shaped rod and the upper mold in the initial state. The gap between the U-shaped rod and the upper mold can make the upper mold move a larger distance, making it easier to remove the molded inductor.

[0022] Preferably, the lower mold is equipped with a lifting assembly, which includes a pneumatic chamber fixed in the lower mold, a piston at one end of the pneumatic chamber is slidably connected to a pneumatic ejector rod, and a piston at the other end of the pneumatic chamber is slidably connected to an extrusion rod, the pneumatic ejector rod is located at the bottom of the two connecting rods, and the extrusion rod is located above the U-shaped rod with a gap. When the U-shaped rod is continuously squeezed and moved upward, it will touch the extrusion rod and drive the extrusion rod to move upward. At this time, the pneumatic ejector rod will push the connecting rod to move upward. At this time, the ejector block fixed at the top of the connecting rod will push out the molded inductor, making it convenient to remove the molded inductor.

[0023] The benefits of this application are:

[0024] (1) The present application sets an upper mold assembly with an adjustable pressure head. When molding inductors of different thicknesses, the first dual-axis motor can be used to control the movement of the trapezoidal pressure block, and then the trapezoidal pressure block is used to squeeze the pressure head to move, thereby adjusting the distance between the upper mold and the pressure head, thereby achieving the effect of adjusting the pressure head, so that the present application can be applied to the molding operation of inductors of various thicknesses.

[0025] (2) The present application sets a vibration component. When the second dual-axis motor is working, the second rotating rod is controlled to rotate through the elastic transmission belt. At this time, multiple elastic knocking blocks on the second rotating rod will knock the pressure head, thereby achieving the effect of vibration compaction.

[0026] (3) The present application sets a demolding assembly. When the upper mold assembly moves upward, the upper mold will squeeze the U-shaped rod. As the U-shaped rod moves upward, the tooth group on its side will drive the second gear to rotate, and the second gear will drive the fourth rotating rod to rotate. The fourth rotating rod drives the third rotating rod to rotate through a rubber transmission belt. When the third rotating rod rotates, multiple annular vibration blocks fixed on its outside will continuously knock on the bottom of the connecting rod, and the vibration will be transmitted to the top block through the connecting rod.

The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Example

[0050] A method for manufacturing a molded integrally formed inductor comprises the following steps:

[0051] S1 preparing a powder material, wherein the powder material comprises carbonyl powder and epoxy resin;

[0052] S2: molding to prepare an integrally formed inductor blank, wherein the powder material and the coil in S1 are integrally die-casted through a molding assembly to obtain an integrally formed inductor blank;

[0053] S3 baking, baking the integrally formed inductor body to cure the epoxy resin;

[0054] S4 soaking, putting the baked one-piece molded inductor blank into anti-rust oil at room temperature of 25-28° C. for 5-7 minutes;

[0055] S5 baking, baking the soaked integrally formed inductor blank to solidify the anti-rust oil on the surface of the integrally formed inductor blank to obtain an integrally formed inductor semi-finished product, the baking time is 20-25 minutes, and the baking temperature is 120-125° C.;

[0056] S6 cooling, naturally cooling the one-piece molded inductor semi-finished product to obtain a finished product.

[0057] See also Figure 1-Figure 4 The present embodiment provides a manufacturing device for a molded integrally formed inductor, comprising a base 100, a lower mold 400 is mounted on the top of the base 100, four positioning slide bars 300 distributed in a quadrangular shape are threadedly connected to the base 100, a top plate 200 is mounted on the top of the positioning slide bar 300 through a nut, a telescopic hydraulic rod 500 is embedded in the top plate 200, and an upper mold assembly 600 is connected to the bottom of the telescopic hydraulic rod 500;

[0058] The upper mold assembly 600 includes:

[0059] The upper mold 610 is slidably connected to the four positioning slide bars 300, and a multi-groove positioning plate 620 is fixed inside the upper mold 610. A plurality of circular grooves are opened at the bottom of the upper mold 610, and a pressure head 630 is penetrated and slidably connected in each circular groove. A positioning slide plate 640 slidably connected in the multi-groove positioning plate 620 is fixed on the side of each pressure head 630, and one end of the positioning slide plate 640 is fixed on the pressure head 630, and the other end is slidably connected to the multi-groove positioning plate 620. The movement trajectory of the ram 630 is limited by the movement trajectory of the positioning slide 640 to prevent the ram 630 from deflecting when moving. A spring is fixed between the bottom of each positioning slide 640 and the inner wall of the upper mold 610. When the ram 630 moves downward, the positioning slide 640 will move downward with it, and the spring will be squeezed to accumulate elastic potential energy. Subsequently, when there is no external force on the ram 630, the spring's rebound force will drive the positioning slide 640 and the ram 630 to reset.

[0060] A trapezoidal pressing block 650 is slidably connected in the upper mold 610 for extruding the pressing head 630. The top of the pressing head 630 is provided with an inclined groove matched with the inclined surface of the trapezoidal pressing block 650, and the inclined surface of the trapezoidal pressing block 650 is slidably connected with the inclined groove at the top of the pressing head 630. The upper surface of each of the trapezoidal pressing blocks 650 is equipped with a latching tooth group. By providing an inclined groove matched with the inclined surface of the trapezoidal pressing block 650 at the top of the pressing head 630, the pressure direction of the trapezoidal pressing block 650 will not be offset when applying pressure to the pressing head 630, and the friction loss between the trapezoidal pressing block 650 and the pressing head 630 is smaller.

[0061] A first dual-axis motor 680 is fixed to the outside of the upper mold 610. The first rotating rods 660 are fixed to the two output shafts of the first dual-axis motor 680. The two first rotating rods 660 are fixed with a plurality of first gears 670 that mesh with the upper surface gear groups of the trapezoidal pressing blocks 650. When the first dual-axis motor 680 is working, the two first rotating rods 660 are controlled to rotate at the same time. At this time, the first gears 670 set on the two first rotating rods 660 will rotate at the same time, thereby simultaneously controlling the movement of the six trapezoidal pressing blocks 650, thereby The six pressing heads 630 are moved simultaneously, which has the effect of quickly controlling and adjusting the pressing heads 630. By setting up an upper mold assembly 600 with an adjustable pressing head 630, when molding inductors of different thicknesses, the trapezoidal pressing block 650 can be controlled to move by the first dual-axis motor 680, and then the trapezoidal pressing block 650 is used to squeeze the pressing head 630 to move, thereby adjusting the distance between the upper mold 610 and the pressing head 630, thereby achieving the effect of adjusting the pressing head 630, so that the present application can be applicable to the molding operation of inductors of various thicknesses.

[0062] The specific operation of the above-mentioned device during operation is as follows: first, the length of the pressure head 630 is adjusted according to the specifications of the molded inductor, and then the first dual-axis motor 680 is started, and the two output shafts of the first dual-axis motor 680 are used to simultaneously control the two first rotating rods 660 to rotate. At this time, the first gears 670 set on the two first rotating rods 660 will rotate simultaneously. Since the six first gears 670 are respectively in meshing state with the tooth groups on the six trapezoidal pressing blocks 650, when the first gears 670 rotate, the trapezoidal pressing blocks 650 will be controlled to move through the tooth groups on the trapezoidal pressing blocks 650. Therefore, when the six first gears 670 rotate, the six trapezoidal pressing blocks 650 are controlled to move at the same time, and the inclined surfaces of the two trapezoidal pressing blocks 650 are used to squeeze the inclined grooves at the top of the pressing heads 630, so that the six pressing heads 630 move downward at the same time. When the pressing heads 630 move to a suitable distance, the first dual-axis motor 680 is turned off. As the pressing heads 630 move downward, the positioning slide plate 640 will follow and move downward, and the spring will be squeezed at this time, so that the spring accumulates elastic potential energy. Subsequently, when there is no external force acting on the pressing heads 630, the resilience of the spring will drive the positioning slide plate 640 and the pressing heads 630 to reset.

[0063] After the pressure head 630 is adjusted, the inductor raw material is placed into the lower mold 400, and then the upper mold assembly 600 is controlled to move downward as a whole through the telescopic hydraulic rod 500, and the inductor molding operation is performed under the action of the upper mold 610, the lower mold 400 and the pressure head 630.

[0064] It is worth noting that see Figure 3-Figure 5 In the present application, two groups of vibration components 690 are symmetrically arranged in the upper mold 610 for increasing the pressing effect of the pressure head 630. The vibration component 690 includes a second double-axis motor 691 and a second rotating rod 693. Both sides of the second rotating rod 693 are rotatably connected with a first bracket 692. The two first brackets 692 are fixed on the positioning slide 640. The second double-axis motor 691 is fixed on the top of the upper mold 610, and the two output shafts of the second double-axis motor 691 are transmission-connected with the second rotating rod 693 through an elastic transmission belt 695. Since the position of the pressure head 630 changes, The elastic transmission belt 695 is used to ensure the transmission between the second rotating rod 693 and the second dual-axis motor 691. The second rotating rod 693 is equipped with a plurality of elastic knocking blocks 694. The elastic knocking blocks 694 are arranged in a ring shape in groups of three on the second rotating rod 693, and every two groups of the elastic knocking blocks 694 correspond to one pressing head 630. When the second dual-axis motor 691 is working, the second rotating rod 693 is controlled to rotate by the elastic transmission belt 695. At this time, the plurality of elastic knocking blocks 694 on the second rotating rod 693 will knock on the pressing head 630, thereby achieving the effect of vibration compaction.

[0065] When the above-mentioned vibration component 690 is actually working, after the upper mold 610 and the lower mold 400 are fitted together, the two second dual-axis motors 691 are started. At this time, the two output shafts of the two second dual-axis motors 691 respectively drive the two second rotating rods 693 to rotate through the two elastic transmission belts 695. At this time, the multiple elastic knocking blocks 694 on the second rotating rods 693 will knock the pressure head 630, thereby achieving the effect of vibration compaction. Since the pressure head 630 will move during actual use, the setting of the elastic transmission belt 695 can ensure the transmission of the second rotating rod 693 and the second dual-axis motor 691.

[0066] For further information, see Figure 6-Figure 9 The lower mold 400 is equipped with a demoulding assembly 700, and the demoulding assembly 700 includes a top block 710, a third rotating rod 740, a fourth rotating rod 760, and a U-shaped rod 790. There are six top blocks 710 in total and they are slidably connected in the mold groove of the lower mold 400, and the bottoms of every three top blocks 710 are connected by a connecting rod 720. A plurality of second brackets 730 for supporting the connecting rod 720 are fixed to the bottom of the inner wall of the lower mold 400. The third rotating rod 740 is fixed by a positioning The block is rotatably connected to the inside of the lower mold 400, and a plurality of annular vibration blocks 750 are fixed on the third rotating rod 740. The fourth rotating rod 760 is rotatably connected to the bottom of the top plate 200 through the positioning block. One end of the fourth rotating rod 760 is transmission-connected to the third rotating rod 740 through a rubber transmission belt 770. The other end of the fourth rotating rod 760 is fixed with a second gear 780. The U-shaped rod 790 penetrates and is slidably connected to the top plate 200. One end of the U-shaped rod 790 is close to the second gear 780. A latching tooth group is provided and meshes with the second gear 780. When the upper mold assembly 600 moves upward, the upper mold 610 will squeeze the U-shaped rod 790. As the U-shaped rod 790 moves upward, the latching tooth group on its side will drive the second gear 780 to rotate, and the second gear 780 will drive the fourth rotating rod 760 to rotate. The fourth rotating rod 760 drives the third rotating rod 740 to rotate through the rubber transmission belt 770. When the third rotating rod 740 rotates, the multiple annular vibration blocks 750 fixed on its outer side will continuously knock on the continuous rotating rod 740. At the bottom of the connecting rod 720, the vibration is transmitted to the top block 710 through the connecting rod 720, and the molded inductor is separated from the lower mold 400 through the vibration on the top block 710, which is convenient for subsequent demolding operations. The annular vibration block 750 is located below the connecting rod 720 and is in a fitted state. In the initial state, there is a gap between the U-shaped rod 790 and the upper mold 610. The gap between the U-shaped rod 790 and the upper mold 610 can make the upper mold 610 move a larger distance, which is convenient for removing the molded inductor.

[0067] When the demolding assembly 700 is actually working, after the molding operation of the inductor is completed, the telescopic hydraulic rod 500 is used to control the upper mold 610 to move upward. As the upper mold 610 moves, the U-shaped rod 790 will be squeezed. At this time, the U-shaped rod 790 moves upward, and the tooth group on this side will drive the second gear 780 to rotate. The second gear 780 drives the fourth rotating rod 760 to rotate, and the fourth rotating rod 760 drives the third rotating rod 740 to rotate through the rubber transmission belt 770. When the third rotating rod 740 rotates, the multiple annular vibration blocks 750 fixed on the outside will continuously knock on the bottom of the connecting rod 720, and the vibration will be transmitted to the top block 710 through the connecting rod 720. The molded inductor is separated from the lower mold 400 through the vibration on the top block 710.

[0068] Finally, see Figure 10-11 In the present application, a lifting assembly 800 is assembled in the lower mold 400, and the lifting assembly 800 includes a pneumatic chamber 810 fixed in the lower mold 400, and a piston at one end of the interior of the pneumatic chamber 810 is slidably connected to a pneumatic ejector rod 820, and a piston at the other end of the interior of the pneumatic chamber 810 is slidably connected to an extrusion rod 830, and the pneumatic ejector rod 820 is located at the bottom of the two connecting rods 720, and the extrusion rod 830 is located above the U-shaped rod 790 with a gap. Only when the demolding assembly 700 is finished working, the upper mold 610 moves up again to trigger the movement of the extrusion rod 830.

[0069] When the above-mentioned lifting component 800 is actually working, after the demoulding component 700 is vibrated and separated, the telescopic hydraulic rod 500 is used to control the upper mold 610 to move upward again. As the upper mold 610 moves, the U-shaped rod 790 continues to rise. At this time, the U-shaped rod 790 will touch and push the extrusion rod 830 to move upward. At this time, the gas pressure in the air pressure chamber 810 becomes larger, causing the air pressure push rod 820 to move upward. At this time, due to the upward movement of the air pressure push rod 820, the two connecting rods 720 will be squeezed upward at the same time, thereby causing the six ejector blocks 710 to move upward, pushing out the inductor that has been separated from the lower mold 400, making it convenient for the staff to take it.

[0070] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
