Description

Technical Field

[0001] The 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 a magnetic core). It is a transformer widely used in power adapters for household appliances, electronic equipment, and other electronic equipment 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 of the prior art, such as mobile phone chargers, laptop power adapters, etc. 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 secondary windings to meet the needs of small current output; thicker copper wires are used for primary windings 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 for winding primary and secondary windings with thick and thin coils.

[0004] During the process of winding the primary winding and the secondary winding, the coil spacing of the thick and thin copper wires wound on the primary winding and the secondary winding 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 increasing the local magnetic 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 solve the technical problems in the prior art in view of the deficiencies in the prior art.

[0006] The purpose of the present invention can be achieved by the following technical solutions: a transformer with integrated inductance, which includes a substrate and a workbench, a control console and a roller frame installed on the substrate, the control console drives the threading assembly to rotate, the workbench is installed with a positioning roller, the positioning roller clamps an annular ferrite magnet, and the annular ferrite magnet is inserted into the interior of the threading assembly, the workbench is installed with a driving distance component and a second motor, the workbench is installed with a support plate, and the support plate is installed with a first motor; the driving distance component includes an outer cylinder and a rotating cylinder that can be automatically reset, the second motor drives the outer cylinder to rotate, a plurality of spacer plates are arranged equidistantly on the outer cylinder, and a slot is provided between two adjacent spacer plates; the outer cylinder is offsetly installed with a rotating cylinder, a convex shaft is rotatably installed in the rotating cylinder, the convex shaft and the outer cylinder are concentrically arranged, an inner gear ring is installed on the rotating cylinder, a part of the gear is installed on the convex shaft, and the part of the gear is meshed with the inner gear ring, the first motor drives the convex shaft and the part of the gear to rotate synchronously, a push plate is slidably installed in the rotating cylinder, and the convex shaft abuts against the push plate; during the rotation of the convex shaft, the convex surface on the convex shaft abuts against the push plate, so that the push plate passes through the slot.

[0007] As a further optimization or improvement of the present solution, a sliding frame is installed on the support plate, a connecting rod is installed on the rotating drum, the connecting rod is located in the sliding frame and slides, 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 the present solution, the threading assembly includes an arc frame one and an arc frame two rotatably mounted on the arc frame one, a magnetic block is mounted on the arc frame one, a magnetic suction groove is provided on the arc frame two, the magnetic block and the magnetic suction groove attract each other, and wire grooves are provided on both the arc frame one and the arc frame two, and the copper wire on the winding 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 the present solution, the cam shaft is made of magnetic material, the push plate is made of magnetic metal, and during the rotation of the cam shaft, the push plate fits against the outer wall of the cam shaft.

[0011] As a further optimization or improvement of the present solution, a needle roller is installed at 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 the present 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: (1) The present invention controls the combined circular ring of arc frame 1 and arc frame 2 to rotate through a control console, and simultaneously turns on motor 2, which drives the outer cylinder to rotate, and drives the annular ferrite magnet to rotate through the spacing plate on the outer cylinder, so that the thick copper wire in the wire groove is wound on the annular ferrite magnet. During the rotation of the outer cylinder, the spacing plate separates the thick copper wire wound on the annular ferrite magnet at a fixed distance, ensuring that the winding density of the thick copper wire on the primary coil is uniform and avoiding excessive coil gap.

[0014] (2) The present invention drives the cam shaft and some gears to rotate synchronously through a motor. During the rotation of the cam shaft, the convex surface of the cam shaft pushes the push plate into the slot. As the some gears rotate, the some gears mesh with the inner gear ring, and the some gears drive the drum to rotate intermittently. During the rotation of the drum, the drum compresses the spring through the connecting rod on it. At the same time, the rotation of the 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 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 of the thin copper wires on the secondary coil is consistent with the spacing of the thick copper wires on the primary coil, improve the electromagnetic induction efficiency of the transformer, and reduce the magnetic leakage phenomenon of the transformer.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0028] See also Figure 1-Figure 10 A transformer with integrated inductance 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 equipped with a positioning roller 7, which clamps an annular ferrite magnet 8, and the annular ferrite magnet 8 is inserted into the interior of the threading assembly 5. The workbench 2 is equipped with a driving distance component 6 and a motor 2 10. The workbench 2 is equipped with a support plate 11, and a motor 1 9 is installed on the support plate 11; the driving distance component 6 includes an outer cylinder 601 and a rotating cylinder 602 that can automatically reset. The motor 2 10 drives the outer cylinder 601 to rotate. A plurality of spacer plates 607 are arranged equidistantly on the outer cylinder 601. Two adjacent spacer plates 607 are arranged equidistantly. 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 meshed with the inner gear ring 604; the motor 19 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.

[0029] It should be noted that the arc frame 1 501 and the arc frame 2 502 are combined into a ring, and the purpose of winding the copper wire on the ring ferrite magnet 8 is achieved by placing the ring ferrite magnet 8 in the ring. The console 3 has a built-in drive device, and the control panel on the console 3 controls the operation of the drive device, and then the drive device drives the arc frame 1 501 and the arc frame 2 502 to rotate. The working method and principle of the console 3 are prior art, and this solution will not be repeated, and it does not affect the integrity of this solution.

[0030] Specifically, the motor 2 10 is connected to the outer cylinder 601 via a reducer 12 .

[0031] Specifically, the distance between two adjacent spacers 607 is equal to the diameter of the thick copper wire. 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 the inner walls of the two adjacent spacers 607, so that the spacer 607 separates the thick copper wire at a fixed distance and drives the annular ferrite magnet 8 to rotate.

[0032] Primary coil winding; When in use, the arc frame 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 absorb 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.

[0033] The annular ferrite magnet 8 is fixed between the positioning rollers 7, and a thick copper wire winding roller is installed on the winding roller frame 4. The thick copper wire of a fixed length is wound in the wire groove 503 on the arc frame 1 501 and the arc frame 2 502. The combined circular ring of the arc frame 1 501 and the arc frame 2 502 is controlled to rotate by the control console 3, and the motor 2 10 is turned on at the same time. The motor 2 10 drives the outer cylinder 601 to rotate, and the annular ferrite magnet 8 is driven to rotate through the partition plate 607 on the outer cylinder 601, so that the thick copper wire in the wire groove 503 is wound on the annular ferrite magnet 8. During the rotation of the outer cylinder 601, the partition plate 607 separates the thick copper wire wound on the annular ferrite magnet 8 at a fixed spacing (the fixed spacing is the thickness of the partition plate 607), ensuring that the winding density of the thick copper wire on the primary coil is uniform and avoiding excessive coil gap. After the winding of the primary coil is completed, the primary coil is removed from the positioning roller 7.

[0034] It should be noted that the primary coil and secondary coil of this scheme are respectively wound with thick copper wire and thin copper wire. After the thin copper wire is wound on the secondary coil, since the diameter of the thin copper wire is smaller than that of the thick copper wire, the spacing between the thin copper wires on the secondary coil cannot be consistent with the spacing between the thick copper wires on the primary coil. When the transformer is in use, it is easy to cause the electromagnetic induction efficiency of the transformer to decrease and the leakage magnetic field to increase, resulting in energy loss, increased transformer heating, and reduced transformer service life. This scheme improves the problem of the spacing between the thin copper wires on the secondary coil and the spacing between the thick copper wires on the primary coil being inconsistent through the following scheme.

[0035] Secondary coil winding; When in use, the arc frame 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 absorb 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.

[0036] 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, 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.

[0037] Specifically, during the operation of the motor 9, the motor 9 drives the cam 603 and the part of the gear 605 to rotate synchronously, see Fig.10During the rotation of the convex shaft 603, the convex surface of the convex shaft 603 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, and the partial gear 605 drives the rotating drum 602 to rotate intermittently. During the rotation of the rotating drum 602, the rotating drum 602 compresses the spring 611 through the connecting rod 610 thereon. At the same time, the rotation of the rotating drum 602 drives the push plate 606 to move the thin copper wire between the spacer plates 607, so that the thin copper wire on the annular ferrite magnet 8 is attached to one side of the spacer plate 607. As the rotating drum 602 continues to rotate, the rotating drum 602 drives the outer drum 601 to rotate through the push plate 606. During this process, the spacer plate 607 on the outer drum 601 drives the annular ferrite magnet 8 to rotate. As part of the gear 605 rotates, part of the gear 605 disengages from the inner gear ring 604. At this time, the spring 611 rebounds and drives the drum 602 to reset. As the convex shaft 603 rotates, the convex surface of the convex shaft 603 moves away from the push plate 606. At this time, the push plate 606 disengages from the slot 608. As the motor 9 continues to run, the push plate 606 is inserted into the next group of slots 608. At the same time, the push plate 606 pushes the next group of thin copper wires on the annular ferrite magnet 8 to fit one side of the spacer plate 607, and separates the thin copper wires wound on the annular ferrite magnet 8 at a fixed spacing (the fixed spacing is the thickness of the spacer plate 607). The present invention can keep the spacing of the thin copper wires on the secondary coil consistent with the spacing of the thick copper wires on the primary coil by driving the spacing component 6, thereby improving the electromagnetic induction efficiency of the transformer and reducing the magnetic leakage phenomenon of the transformer. After the secondary coil is wound, the secondary coil is removed from the positioning roller 7.

[0038] It should be noted that the manufactured transformer is finally integrated with the inductor to complete the manufacture of the inductor transformer.

[0039] See also Fig. 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 the connecting rod 610 is connected to the inner wall of the sliding frame 609 through a spring 611 .

[0040] 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.

[0041] See also Figure 3The threading assembly 5 includes an arc frame 501 and an arc frame 502 rotatably mounted on the arc frame 501. A magnetic block 504 is mounted on the arc frame 501. A magnetic suction groove 505 is provided on the arc frame 502. The magnetic block 504 and the magnetic suction groove 505 attract each other. Both the arc frame 501 and the arc frame 502 are provided with a wire placement groove 503. The copper wire on the winding roller frame 4 is wound around the threading assembly 5 through the wire placement groove 503.

[0042] 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 connected by mutual attraction through the magnetic suction groove 505 and the magnetic block 504, thereby improving the convenience of the threading assembly 5.

[0043] Specifically, the convex shaft 603 is made of magnetic material, and the push plate 606 is made of magnetic metal. When the convex shaft 603 rotates, the push plate 606 is attached to the outer wall of the convex shaft 603. It should be noted that the magnetic suction groove 505 has a magnet sheet built therein, and the magnet sheet and the magnetic block 504 attract each other.

[0044] See also Fig.10 The push plate 606 is provided with a needle roller at one end close to the convex shaft 603, and the push plate 606 is attached to 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.

[0045] Working principle of the present invention: Primary coil winding; Rotate the arc frame 502 on the arc frame 501 to separate the connecting ends of the arc frame 501 and the arc frame 502, and place the annular ferrite magnet 8 in the arc frame 501 through the opening of the arc frame 501. Finally, rotate the arc frame 502 to make the magnetic block 504 on the arc frame 501 absorb the magnetic suction groove 505 on the arc frame 502 to achieve the connection between the arc frame 501 and the arc frame 502.

[0046] The annular ferrite magnet 8 is fixed between the positioning rollers 7, and a thick copper wire winding roller is installed on the winding roller frame 4. The thick copper wire of a fixed length is wound in the wire groove 503 on the arc frame 1 501 and the arc frame 2 502. The combined circular ring of the arc frame 1 501 and the arc frame 2 502 is controlled to rotate by the control console 3, and the motor 2 10 is turned on at the same time. The motor 2 10 drives the outer cylinder 601 to rotate, and the annular ferrite magnet 8 is driven to rotate through the partition plate 607 on the outer cylinder 601, so that the thick copper wire in the wire groove 503 is wound on the annular ferrite magnet 8. During the rotation of the outer cylinder 601, the partition plate 607 separates the thick copper wire wound on the annular ferrite magnet 8 at a fixed spacing (the fixed spacing is the thickness of the partition plate 607), ensuring that the winding density of the thick copper wire on the primary coil is uniform and avoiding excessive coil gap. After the winding of the primary coil is completed, the primary coil is removed from the positioning roller 7.

[0047] Secondary coil winding; When in use, the arc frame 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 absorb 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.

[0048] 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, 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.

[0049] Specifically, during the operation of the motor 9, the motor 9 drives the cam 603 and the part of the gear 605 to rotate synchronously, see Fig.10During the rotation of the convex shaft 603, the convex surface of the convex shaft 603 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, and the partial gear 605 drives the rotating drum 602 to rotate intermittently. During the rotation of the rotating drum 602, the rotating drum 602 compresses the spring 611 through the connecting rod 610 thereon. At the same time, the rotation of the rotating drum 602 drives the push plate 606 to move the thin copper wire between the spacer plates 607, so that the thin copper wire on the annular ferrite magnet 8 is attached to one side of the spacer plate 607. As the rotating drum 602 continues to rotate, the rotating drum 602 drives the outer drum 601 to rotate through the push plate 606. During this process, the spacer plate 607 on the outer drum 601 drives the annular ferrite magnet 8 to rotate. As part of the gear 605 rotates, part of the gear 605 disengages from the inner gear ring 604. At this time, the spring 611 rebounds and drives the drum 602 to reset. As the convex shaft 603 rotates, the convex surface of the convex shaft 603 moves away from the push plate 606. At this time, the push plate 606 disengages from the slot 608. As the motor 9 continues to run, the push plate 606 is inserted into the next group of slots 608. At the same time, the push plate 606 pushes the next group of thin copper wires on the annular ferrite magnet 8 to fit one side of the spacer plate 607, and separates the thin copper wires wound on the annular ferrite magnet 8 at a fixed spacing (the fixed spacing is the thickness of the spacer plate 607). The present invention can keep the spacing of the thin copper wires on the secondary coil consistent with the spacing of the thick copper wires on the primary coil by driving the spacing component 6, thereby improving the electromagnetic induction efficiency of the transformer and reducing the magnetic leakage phenomenon of the transformer. After the secondary coil is wound, the secondary coil is removed from the positioning roller 7.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
