Description

Technical Field

[0001] The present invention belongs to the technical field of transformer production, and in particular relates to a transformer with integrated inductance. Background Art

[0002] A toroidal transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are a primary coil, a secondary coil, and an iron core (or magnetic core). It is a transformer widely used in power adapters for home appliances, electronic devices, and other electronic devices with high technical requirements. An integrated inductor transformer is a power electronic device that integrates the functions of an inductor and a toroidal transformer.

[0003] Power adapters in the prior art, such as mobile phone chargers and laptop power adapters. These devices need to convert alternating current into direct current and have strict requirements on volume and weight. The transformer with a toroidal core is wound with different copper wires, which can achieve efficient power conversion in a limited space. Thinner copper wires are used for the secondary winding to meet the needs of small current output; thicker copper wires are used for the primary winding to withstand larger input currents. When the toroidal transformer is integrated with an inductor, the leakage inductance and parasitic capacitance can be reduced, efficient voltage conversion can be achieved, and the conversion efficiency of the power module can be improved. For example, the specification of the invention patent with publication number CN116705477B uses a process of winding the primary and secondary windings with thick and thin coils.

[0004] During the process of winding the primary and secondary windings, the coil spacing of the thick and thin copper wires wound on the primary and secondary windings is difficult to control, which can easily cause a large deviation in the coil gap after winding, resulting in uneven winding density of the coil on the magnetic core and increased local core loss of the coil. Summary of the Invention

[0005] The purpose of the present invention is to provide a transformer with integrated inductance to address the deficiencies of the prior art and solve the technical problems in the prior art.

[0006] The objectives of the present invention can be achieved by the following technical solutions: A transformer with integrated inductance, comprising a substrate and a workbench, a control console and a roller frame mounted on the substrate, wherein the control console drives a threading assembly to rotate, a positioning roller is mounted on the workbench, the positioning roller clamps an annular ferrite magnet, and the annular ferrite magnet is inserted into the interior of the threading assembly, a driving and spacing assembly and a second motor are mounted on the workbench, a support plate is mounted on the workbench, and a first motor is mounted on the support plate; the driving and spacing assembly comprises an outer cylinder and an automatically resettable rotating cylinder, the second motor drives the outer cylinder to rotate, a plurality of spacers are arranged at equal intervals on the outer cylinder, and a slot is defined between two adjacent spacers; the rotating cylinder is offset mounted in the outer cylinder, a convex shaft is rotatably mounted in the rotating cylinder, the convex shaft and the outer cylinder are concentrically arranged, an inner gear ring is mounted on the rotating cylinder, a partial gear is mounted on the convex shaft, and the partial gear is meshed with the inner gear ring, the first motor drives the convex shaft and the partial gear to rotate synchronously, a push plate is slidably mounted in the rotating cylinder, and the convex shaft abuts the push plate; during the rotation of the convex shaft, the convex surface of the convex shaft abuts the push plate, causing the push plate to pass through the slot.

[0007] As a further optimization or improvement of this solution, a sliding frame is installed on the support plate, and a connecting rod is installed on the rotating drum. The connecting rod slides in the sliding frame, and the connecting rod is connected to the inner wall of the sliding frame through a spring.

[0008] As a further optimization or improvement of this solution, the threading assembly includes an arc frame 1 and an arc frame 2 rotatably mounted on the arc frame 1. A magnetic block is mounted on the arc frame 1, and a magnetic groove is provided on the arc frame 2. The magnetic block and the magnetic groove attract each other. Both the arc frame 1 and the arc frame 2 are provided with wire grooves, and the copper wire on the roller frame is wound around the threading assembly through the wire grooves.

[0009] As a further optimization or improvement of this solution, the second motor is connected to the outer cylinder via a reducer.

[0010] As a further optimization or improvement of this solution, the convex shaft is made of magnetic material, and the push plate is made of magnetic metal. During the rotation of the convex shaft, the push plate is attached to the outer wall of the convex shaft.

[0011] As a further optimization or improvement of this solution, a needle roller is installed on one end of the push plate close to the convex shaft, and the push plate is fitted to the outer wall of the convex shaft through the needle roller.

[0012] As a further optimization or improvement of this solution, the distance between two adjacent spacer plates is equal to the diameter of the thick copper wire.

[0013] Beneficial effects of the present invention:

[0014] (1) The present invention controls the rotation of the combined circular ring of arc frame 1 and arc frame 2 through a control console, and simultaneously activates motor 2, which drives the outer cylinder to rotate. This in turn drives the annular ferrite magnet via a spacer plate on the outer cylinder, causing the thick copper wire in the wire slot to be wound around the annular ferrite magnet. During the rotation of the outer cylinder, the spacer plate separates the thick copper wire wound around the annular ferrite magnet at a fixed distance, ensuring a uniform winding density of the thick copper wire on the primary coil and preventing excessive coil gaps.

[0015] (2) The present invention uses a motor to drive the cam shaft and the partial gear to rotate synchronously. During the rotation of the cam shaft, the convex surface of the cam shaft pushes the push plate into the slot. As the partial gear rotates, the partial gear engages with the inner gear ring, and the partial gear drives the rotating drum to rotate intermittently. During the rotation of the rotating drum, the rotating drum compresses the spring through the connecting rod on it. At the same time, the rotation of the rotating drum drives the push plate to move the thin copper wire between the spacer plates, so that the thin copper wire on the annular ferrite magnet fits on one side of the spacer plate, and the thin copper wire wrapped around the annular ferrite magnet is separated at a fixed distance. Ensure that the spacing between the thin copper wires on the secondary coil is consistent with the spacing between the thick copper wires on the primary coil, improve the electromagnetic induction efficiency of the transformer, and reduce the leakage magnetic phenomenon of the transformer.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] See also Figures 1-10 , a transformer with integrated inductance, which includes a substrate 1 and a workbench 2, a control console 3 and a roller frame 4 installed on the substrate 1, the control console 3 drives the threading assembly 5 to rotate, the workbench 2 is installed with a positioning roller 7, the positioning roller 7 clamps the annular ferrite magnet 8, and the annular ferrite magnet 8 is inserted into the interior of the threading assembly 5, the workbench 2 is installed with a driving distance assembly 6 and a motor 2 10, the workbench 2 is installed with a support plate 11, and the support plate 11 is installed with a motor 1 9; the driving distance assembly 6 includes an outer cylinder 601 and an automatically reset rotating cylinder 602, the motor 2 10 drives the outer cylinder 601 to rotate, and a plurality of spacer plates 607 are evenly spaced on the outer cylinder 601, and two adjacent ones are connected. A slot 608 is provided between the spacer plates 607; the rotating cylinder 602 is offsetly installed in the outer cylinder 601, and the convex shaft 603 is rotatably installed in the rotating cylinder 602, and the convex shaft 603 is concentrically arranged with the outer cylinder 601. An inner gear ring 604 is installed on the rotating cylinder 602, and a partial gear 605 is installed on the convex shaft 603, and the partial gear 605 is engaged with the inner gear ring 604. The motor 9 drives the convex shaft 603 and the partial gear 605 to rotate synchronously, and a push plate 606 is slidably installed in the rotating cylinder 602, and the convex shaft 603 abuts against the push plate 606; during the rotation of the convex shaft 603, the convex surface on the convex shaft 603 abuts against the push plate 606, so that the push plate 606 passes through the slot 608.

[0030] It should be noted that arc frame 1 501 and arc frame 2 502 are combined into a circular ring. By placing annular ferrite magnet 8 within the ring, copper wire can be wound around the annular ferrite magnet 8. The control console 3 has a built-in drive device, which is controlled by a control panel on the control console 3. The drive device then drives the combined circular ring of arc frame 1 501 and arc frame 2 502 to rotate. The operating method and principle of the control console 3 are prior art and will not be further described in this solution as it does not affect the integrity of this solution.

[0031] Specifically, the motor 2 10 is connected to the outer cylinder 601 via the reducer 12 .

[0032] Specifically, the distance between two adjacent spacers 607 is equal to the diameter of the thick copper wire.

[0033] It should be noted that the spacing between two adjacent spacers 607 is arranged according to the diameter of the thick copper wire, so that when the outer cylinder 601 and the spacer 607 thereon are rotating, the thick copper wire wrapped on the annular ferrite magnet 8 just fits into the inner walls of the two adjacent spacers 607, so that the spacer 607 separates the thick copper wire at a fixed distance while driving the annular ferrite magnet 8 to rotate.

[0034] Primary coil winding;

[0035] During use, the arc frame 2 502 on the arc frame 1 501 is rotated to separate the connecting ends of the arc frame 1 501 and the arc frame 2 502, and the annular ferrite magnet 8 is placed in the arc frame 1 501 through the opening of the arc frame 1 501. Finally, the arc frame 2 502 is rotated to make the magnetic block 504 on the arc frame 1 501 adsorb the magnetic groove 505 on the arc frame 2 502, thereby realizing the connection between the arc frame 1 501 and the arc frame 2 502.

[0036] An annular ferrite magnet 8 is secured between positioning rollers 7. A thick copper wire reel is mounted on the reel frame 4. A fixed length of thick copper wire is wound into the wire slot 503 on the arc frame 1 501 and the arc frame 2 502. The combined circular ring of arc frame 1 501 and arc frame 2 502 is rotated by the control console 3. Simultaneously, motor 2 10 is activated, driving the outer cylinder 601. This, in turn, drives the annular ferrite magnet 8 via the spacer 607 on the outer cylinder 601, causing the thick copper wire in the wire slot 503 to wind around the annular ferrite magnet 8. As the outer cylinder 601 rotates, the spacer 607 separates the thick copper wire wound around the annular ferrite magnet 8 at a fixed distance (the distance being the thickness of the spacer 607). This ensures uniform winding density of the thick copper wire on the primary coil and prevents excessive gaps between the coils. After winding the primary coil, the primary coil is removed from the positioning rollers 7.

[0037] It should be noted that in this solution, thick copper wire and thin copper wire are wound around the primary and secondary coils, respectively. After the thin copper wire is wound around the secondary coil, the diameter of the thin copper wire is smaller than that of the thick copper wire, so the spacing between the thin copper wires on the secondary coil and the thick copper wires on the primary coil cannot be consistent. When the transformer is in use, this can easily cause the electromagnetic induction efficiency of the transformer to decrease and magnetic leakage to increase, resulting in energy loss, increased transformer heating, and a shortened transformer service life. This solution improves the problem of inconsistent spacing between the thin copper wires on the secondary coil and the thick copper wires on the primary coil through the following solution.

[0038] Secondary coil winding;

[0039] During use, the arc frame 2 502 on the arc frame 1 501 is rotated to separate the connecting ends of the arc frame 1 501 and the arc frame 2 502, and the annular ferrite magnet 8 is placed in the arc frame 1 501 through the opening of the arc frame 1 501. Finally, the arc frame 2 502 is rotated to make the magnetic block 504 on the arc frame 1 501 adsorb the magnetic groove 505 on the arc frame 2 502, thereby realizing the connection between the arc frame 1 501 and the arc frame 2 502.

[0040] Fix the annular ferrite magnet 8 between the positioning rollers 7, then replace the thick copper wire reel on the reel frame 4 with a thin copper wire reel, and wind the thin copper wire of a fixed length into the wire groove 503 on the arc frame 1 501 and the arc frame 2 502. Control the combined circular ring of the arc frame 1 501 and the arc frame 2 502 to rotate through the control console 3, and start the motor 1 9 at the same time. The motor 1 9 drives the annular ferrite magnet 8 to rotate by driving the fixed distance component 6, so that the thin copper wire in the wire groove 503 is wound around the annular ferrite magnet 8.

[0041] Specifically, during the operation of the motor 9, the motor 9 drives the cam 603 and the gear 605 to rotate synchronously, see Figure 10As the convex shaft 603 rotates, its convex surface pushes the push plate 606 into the slot 608. As the partial gear 605 rotates, the partial gear 605 meshes with the inner gear ring 604, driving the rotating drum 602 to intermittently rotate. During the rotation of the rotating drum 602, the connecting rod 610 on the rotating drum 602 compresses the spring 611. Simultaneously, the rotation of the rotating drum 602 drives the push plate 606 to move the thin copper wire between the spacer plates 607, causing the thin copper wire on the annular ferrite magnet 8 to contact one side of the spacer plates 607. As the rotating drum 602 continues to rotate, the rotating drum 602 drives the outer drum 601 to rotate via the push plate 606. During this process, the spacer plates 607 on the outer drum 601 drive the annular ferrite magnet 8 to rotate. As part of the gear 605 rotates, it disengages from the inner gear ring 604. At this point, the spring 611 rebounds, causing the rotating drum 602 to return to its original position. As the cam 603 rotates, the convex surface of the cam 603 moves away from the push plate 606, causing the push plate 606 to disengage from the slot 608. As the motor 9 continues to operate, the push plate 606 inserts into the next set of slots 608. Simultaneously, the push plate 606 pushes the next set of thin copper wires on the annular ferrite magnet 8 against one side of the spacer 607, separating the thin copper wires wound around the annular ferrite magnet 8 at a fixed spacing (this fixed spacing is equal to the thickness of the spacer 607). The present invention can maintain the spacing between the thin copper wires on the secondary coil and the thick copper wires on the primary coil by driving the spacing assembly 6, thereby improving the electromagnetic induction efficiency of the transformer and reducing magnetic flux leakage. After the secondary coil is wound, it is removed from the positioning roller 7.

[0042] It should be noted that the manufactured transformer is finally integrated with the inductor to complete the manufacture of the inductor transformer.

[0043] See also Figure 9 A sliding frame 609 is installed on the support plate 11, and a connecting rod 610 is installed on the rotating drum 602. The connecting rod 610 slides in the sliding frame 609 and is connected to the inner wall of the sliding frame 609 through a spring 611.

[0044] It should be noted that, by offsetting the installation of the rotating drum 602, some gears 605 can drive the rotating drum 602 to move intermittently during rotation. At the same time, in conjunction with the connecting rod 610 and the spring 611, some gears 605 can drive the rotating drum 602 to reset intermittently, thereby ensuring that the driving distance component 6 can continuously separate the thin copper wires on the annular ferrite magnet 8 at a fixed distance.

[0045] See also Figure 3The threading assembly 5 includes an arc frame 1 501 and an arc frame 2 502 rotatably mounted on the arc frame 1 501. A magnetic block 504 is mounted on the arc frame 1 501, and a magnetic groove 505 is provided on the arc frame 2 502. The magnetic block 504 and the magnetic groove 505 attract each other. Both the arc frame 1 501 and the arc frame 2 502 are provided with a wire groove 503. The copper wire on the winding roller frame 4 is wound around the threading assembly 5 through the wire groove 503.

[0046] It should be noted that the arc frame 1 501 and the arc frame 2 502 are connected in a rotating manner, and the arc frame 1 501 and the arc frame 2 502 are attracted to each other by the magnetic groove 505 and the magnetic block 504, thereby improving the convenience of the threading component 5.

[0047] Specifically, the convex shaft 603 is made of magnetic material, and the push plate 606 is made of magnetic metal. During the rotation of the convex shaft 603, the push plate 606 is attached to the outer wall of the convex shaft 603. It should be noted that the magnetic groove 505 has a built-in magnet sheet, and the magnet sheet and the magnetic block 504 attract each other.

[0048] See also Figure 10 The push plate 606 is provided with a needle roller at one end thereof close to the convex shaft 603, and the push plate 606 is fitted with the outer wall of the convex shaft 603 through the needle roller. It should be noted that the needle roller on the push plate 606 can reduce the friction between the push plate 606 and the convex shaft 603, thereby increasing the service life of the present invention.

[0049] Working principle of the present invention:

[0050] Primary coil winding;

[0051] Rotate the arc frame 2 502 on the arc frame 1 501 to separate the connecting ends of the arc frame 1 501 and the arc frame 2 502, and place the annular ferrite magnet 8 in the arc frame 1 501 through the opening of the arc frame 1 501. Finally, rotate the arc frame 2 502 so that the magnetic block 504 on the arc frame 1 501 is attracted to the magnetic suction groove 505 on the arc frame 2 502, thereby realizing the connection between the arc frame 1 501 and the arc frame 2 502.

[0052] An annular ferrite magnet 8 is secured between positioning rollers 7. A thick copper wire reel is mounted on the reel frame 4. A fixed length of thick copper wire is wound into the wire slot 503 on the arc frame 1 501 and the arc frame 2 502. The combined circular ring of arc frame 1 501 and arc frame 2 502 is rotated by the control console 3. Simultaneously, motor 2 10 is activated, driving the outer cylinder 601. This, in turn, drives the annular ferrite magnet 8 via the spacer 607 on the outer cylinder 601, causing the thick copper wire in the wire slot 503 to wind around the annular ferrite magnet 8. As the outer cylinder 601 rotates, the spacer 607 separates the thick copper wire wound around the annular ferrite magnet 8 at a fixed distance (the distance being the thickness of the spacer 607). This ensures uniform winding density of the thick copper wire on the primary coil and prevents excessive gaps between the coils. After winding the primary coil, the primary coil is removed from the positioning rollers 7.

[0053] Secondary coil winding;

[0054] During use, the arc frame 2 502 on the arc frame 1 501 is rotated to separate the connecting ends of the arc frame 1 501 and the arc frame 2 502, and the annular ferrite magnet 8 is placed in the arc frame 1 501 through the opening of the arc frame 1 501. Finally, the arc frame 2 502 is rotated to make the magnetic block 504 on the arc frame 1 501 adsorb the magnetic groove 505 on the arc frame 2 502, thereby realizing the connection between the arc frame 1 501 and the arc frame 2 502.

[0055] Fix the annular ferrite magnet 8 between the positioning rollers 7, then replace the thick copper wire reel on the reel frame 4 with a thin copper wire reel, and wind the thin copper wire of a fixed length into the wire groove 503 on the arc frame 1 501 and the arc frame 2 502. Control the combined circular ring of the arc frame 1 501 and the arc frame 2 502 to rotate through the control console 3, and start the motor 1 9 at the same time. The motor 1 9 drives the annular ferrite magnet 8 to rotate by driving the fixed distance component 6, so that the thin copper wire in the wire groove 503 is wound around the annular ferrite magnet 8.

[0056] Specifically, during the operation of the motor 9, the motor 9 drives the cam 603 and the gear 605 to rotate synchronously, see Figure 10As the convex shaft 603 rotates, its convex surface pushes the push plate 606 into the slot 608. As the partial gear 605 rotates, the partial gear 605 meshes with the inner gear ring 604, driving the rotating drum 602 to intermittently rotate. During the rotation of the rotating drum 602, the connecting rod 610 on the rotating drum 602 compresses the spring 611. Simultaneously, the rotation of the rotating drum 602 drives the push plate 606 to move the thin copper wire between the spacer plates 607, causing the thin copper wire on the annular ferrite magnet 8 to contact one side of the spacer plates 607. As the rotating drum 602 continues to rotate, the rotating drum 602 drives the outer drum 601 to rotate via the push plate 606. During this process, the spacer plates 607 on the outer drum 601 drive the annular ferrite magnet 8 to rotate. As part of the gear 605 rotates, it disengages from the inner gear ring 604. At this point, the spring 611 rebounds, causing the rotating drum 602 to return to its original position. As the cam 603 rotates, the convex surface of the cam 603 moves away from the push plate 606, causing the push plate 606 to disengage from the slot 608. As the motor 9 continues to operate, the push plate 606 inserts into the next set of slots 608. Simultaneously, the push plate 606 pushes the next set of thin copper wires on the annular ferrite magnet 8 against one side of the spacer 607, separating the thin copper wires wound around the annular ferrite magnet 8 at a fixed spacing (this fixed spacing is equal to the thickness of the spacer 607). The present invention can maintain the spacing between the thin copper wires on the secondary coil and the thick copper wires on the primary coil by driving the spacing assembly 6, thereby improving the electromagnetic induction efficiency of the transformer and reducing magnetic flux leakage. After the secondary coil is wound, it is removed from the positioning roller 7.
