Description

Technical Field

[0001] The invention relates to the technical field of inductor production, and in particular to a continuous winding device for processing an inductor coil and a use method thereof. Background Art

[0002] A toroidal inductor is an inductive device in the shape of a ring, usually made of ferrite material. It is used in electronic circuits for energy storage and filtering, and mainly works on the principle of electromagnetic induction. The toroidal inductor can convert electrical energy into magnetic energy and release this energy when the current is disconnected. This property makes it particularly useful in DC converters for stabilizing and regulating power supply voltage. The toroidal inductor can be used as a filter in the circuit through its impedance characteristics to high-frequency signals. They can effectively prevent high-frequency noise and interference signals from entering the circuit, maintaining the stability and working performance of the circuit. In electromagnetic compatibility design, the toroidal inductor is also used to suppress and filter electromagnetic interference to ensure that the electromagnetic compatibility of the equipment meets the standards.

[0003] Magnetic ring inductors usually use wires with good conductivity, such as copper wire or aluminum wire, and are wound into coils on magnetic rings. Nowadays, the most commonly used method to make magnetic ring inductors is still alternating intermittent winding. This winding method is not only slow and has low production efficiency, but also the gaps in the wound magnetic ring inductor coils are uneven, affecting the final use. Summary of the invention

[0004] The object of the present invention is to provide a continuous winding device for inductor coil processing and a method of using the same to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A continuous winding device for inductor coil processing includes a magnetic ring positioning table, an L-shaped plate bracket and a wire loader bracket. The bottom of the magnetic ring positioning table is installed by the bracket, and a loading and unloading robot arm is provided on one side of the magnetic ring positioning table. The loading and unloading robot arm loads and unloads the magnetic ring to be wound. The bottom of the L-shaped plate bracket and the wire loader bracket are both provided with a moving module, and the moving modules are connected to the control system circuit. The magnetic ring positioning table positions the magnetic ring, and a winding mechanism is installed on the L-shaped plate bracket. The wire loader bracket is provided with a wire loading mechanism, and the wire loading mechanism embeds the winding wire into the winding mechanism.

[0006] Furthermore, a motor sliding seat is slidably installed at the bottom of the magnetic ring positioning platform, a small electric push rod is connected between the motor sliding seat and the magnetic ring positioning platform, a first motor is installed on the motor sliding seat, and the motor shaft of the first motor passes through the magnetic ring positioning platform.

[0007] Furthermore, a power wheel is installed on the first motor, and two auxiliary wheels are rotatably installed on the magnetic ring positioning platform. The structure of the power wheel is the same as that of the auxiliary wheel. The power wheel and the two auxiliary wheels are evenly distributed in a ring shape. The loading and unloading robotic arms clamp the magnetic ring and move it to the magnetic ring positioning platform. The small electric push rod pushes the motor sliding seat to move, and the motor sliding seat drives the first motor to move. The power wheel moves with the first motor until the power wheel and the two auxiliary wheels simultaneously hold the magnetic ring to complete the loading and positioning of the magnetic ring. The outer layers of the power wheel and the two auxiliary wheels are provided with rubber to increase friction. When the power wheel rotates, the magnetic ring is driven to rotate by friction, that is, the first motor applies pressure to the magnetic ring to position it and drives the magnetic ring to rotate.

[0008] Furthermore, the wire winding mechanism includes an annular shell and a wire winding ring, and notches are provided on the annular shell and the wire winding ring. The wire winding ring is slidably installed in the annular shell, and an electric clamp is provided at a position close to the notch on one side of the annular shell. Closed brackets are provided at the upper and lower ends of the annular shell, and a transmission wheel is rotatably installed inside each of the closed brackets, and the transmission wheel is in contact with the outer contour of the wire winding ring.

[0009] Furthermore, an outer wire groove is provided on the outer ring of the wire winding ring, an inner wire groove is provided on the inner ring of the wire winding ring, a reversing roller is rotatably installed on one end of the wire winding ring, the reversing roller is connected with the outer wire groove and the inner wire groove, the outer side of the outer wire groove is covered with an outer retaining skin, the outer side of the inner wire groove is covered with an inner retaining skin, the outer retaining skin is composed of two retaining skins with trapezoidal cross-sections, the inner retaining skin and the outer retaining skin have the same structure, after the winding wire fills the inner wire groove, it bypasses the reversing roller and continues to fill the outer wire groove, the trapezoidal inclined surfaces of the inner retaining skin and the outer retaining skin make it easier for the winding wire to be embedded in the inner wire groove and the outer wire groove, and the inner retaining skin and the outer retaining skin also prevent the winding wire from escaping from the inner wire groove and the outer wire groove.

[0010] Furthermore, several pairs of convergence rollers are arranged inside the winding ring, and several pairs of the convergence rollers are respectively arranged on both sides of the outer wire groove and on both sides of the inner wire groove. Several pairs of convergence rollers are evenly distributed along the outer wire groove or the inner wire groove, and a coil spring is arranged at the junction of each convergence roller and the winding ring.

[0011] Furthermore, the two transmission wheels are coaxially connected to a driven sprocket, a second motor is installed on the L-shaped plate bracket, a driving sprocket is installed on the second motor, the driving sprocket is located between the two driven sprockets, a chain is connected between the driving sprocket and the two driven sprockets, the second motor drives the driving sprocket to rotate, the driving sprocket drives the two driven sprockets to rotate through the chain, the two driven sprockets drive the two transmission wheels to rotate, the two transmission wheels drive the wire winding ring to rotate in the annular housing through friction, even if one of the transmission wheels is located at the notch of the wire winding ring, the other transmission wheel also keeps in contact with the wire winding ring, driving the wire winding ring to rotate, that is, the second motor drives the wire winding ring to rotate forward or reverse;

[0012] Since the end of the winding wire is clamped by the electric clamp, when the winding ring starts to rotate, the winding wire starts to be wound around the magnetic ring. At this time, the first motor also drives the magnetic ring to rotate. The winding wire can only be drawn out from the position of the notch of the winding ring due to the obstruction of the inner and outer retaining skins. After the winding ring rotates several times, sufficient friction is generated between the winding wire and the magnetic ring so that it will not loosen. The control system then controls the electric clamp to loosen the end of the wire.

[0013] Since the notch of the winding ring is sometimes close to the magnetic ring and sometimes away from the magnetic ring during the rotation process, when the notch is away from the magnetic ring, more winding wire is drawn out from the outer wire slot and the inner wire slot, and when the notch is close to the magnetic ring again, the winding wire will be loose, affecting the uniformity of winding. Therefore, both sides of the outer wire slot and the inner wire slot are provided with convergence rollers. There is friction between the convergence roller and the surface of the embedded winding wire. When the winding wire is drawn out, it will also drive the convergence roller to rotate. When the convergence roller rotates, it relies on the winding spring to accumulate reverse torque. When the winding wire is loose, the winding spring drives the convergence roller to reverse, and the winding wire is retracted into the outer wire slot or the inner wire slot by friction, so that the winding wire is always tightened during the winding process, so that the winding of the winding wire on the magnetic ring is more uniform. After the winding is completed, the loading and unloading robot arm removes the magnetic ring inductor;

[0014] By setting a winding ring larger than the magnetic ring, a sufficient length of winding wire is set in the winding ring in advance, and then continuously wound onto the magnetic ring. Compared with intermittent winding equipment, it is faster, the winding is more uniform and beautiful, and the winding efficiency is higher.

[0015] Furthermore, the wire loading mechanism is connected to the control system circuit, and the wire loading mechanism includes a large electric push rod, a rotating module, and a wire feeder. The large electric push rod is installed on the wire loading device bracket, and the rotating module is installed on the large electric push rod. The wire feeder is arranged at one end of the rotating module away from the large electric push rod. The large electric push rod drives the wire feeder to move in a direction close to or away from the L-shaped plate bracket, and the rotating module drives the wire feeder to rotate around the axis. The wire feeder transmits the winding wire. Under the control of the control system, the moving module controls The L-shaped plate bracket and the wire loader bracket begin to move, so that the wire feeder moves closer to the electric clamp, and the wire feeder sends the winding wire forward for a certain length. The control system clamps the head of the winding wire through the electric clamp, and the mobile module drives the wire loader bracket to move, so that the wire feeder approaches the inner wire groove of the winding ring, squeezes the winding wire through the inner stopper and pushes it into the inner wire groove. As the winding ring rotates, the wire feeder sends out the winding wire, and the winding wire is slowly buried in the inner wire groove. The inner stopper prevents the winding wire buried in the inner wire groove from being pulled away;

[0016] As the inner wire groove is filled, the wire winding ring stops rotating, and the rotating module drives the wire feeder to rotate so that the winding wire bypasses the reversing roller. The control system controls the wire winding ring to rotate in the opposite direction, and the winding wire is squeezed through the outer baffle and pushed into the outer wire groove. The wire winding ring rotates while the wire feeder feeds the winding wire until the outer wire groove is also filled with the winding wire. The winding wire is cut off inside the wire feeder by an electric shear, and the control system uses the moving module to drive the L-shaped plate bracket and the wire loader bracket to return to their positions.

[0017] A method for using a continuous winding device for inductor coil processing comprises the following steps:

[0018] S1: The loading and unloading robot places the magnetic ring to be wound on the magnetic ring positioning table;

[0019] S2: The electric clamp clamps the winding wire end in the wire loading mechanism, and the wire loading mechanism embeds the winding wire into the outer wire groove and the inner wire groove in the winding ring;

[0020] S3: The moving module drives the winding mechanism to move, and the notch on the annular housing and the winding ring moves to the inside of the magnetic ring;

[0021] S4: The first motor drives the magnetic ring to rotate, and the second motor drives the winding ring to rotate, and the winding wire is evenly wound onto the magnetic ring;

[0022] S5: The loading and unloading robot arm unloads the wound magnetic ring.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0024] By setting a first motor to apply pressure to the magnetic ring to position it and drive the magnetic ring to rotate, the second motor drives the winding ring to rotate forward or reverse, and the notch of the winding ring is sometimes close to the magnetic ring and sometimes away from the magnetic ring during rotation. There is friction between the gathering rollers on both sides of the outer wire groove and the inner wire groove and the surface of the embedded winding wire. When the winding wire becomes loose, the coil spring drives the gathering roller to reverse, and the winding wire is retracted into the outer wire groove or the inner wire groove through friction, so that the winding wire is tightened at all times during the winding process, so that the winding of the winding wire on the magnetic ring is more evenly wound. By setting a winding ring larger than the magnetic ring, a winding wire of sufficient length is set in the winding ring in advance, and then continuously wound on the magnetic ring. Compared with intermittent winding equipment, the speed is faster, the winding is more even and beautiful, and the winding efficiency is higher. BRIEF DESCRIPTION OF THE DRAWINGS

The first motor 5 The motor shaft passes through the magnetic ring positioning platform 1, and a power wheel 401 is installed on the first motor 5. Two auxiliary wheels 402 are also rotatably installed on the magnetic ring positioning platform 1. The structure of the power wheel 401 is the same as that of the auxiliary wheel 402. The power wheel 401 and the two auxiliary wheels 402 are evenly arranged in a ring shape. The loading and unloading mechanical arms clamp the magnetic ring and move it to the magnetic ring positioning platform 1. The small electric push rod 7 pushes the motor sliding seat 6 to move, and the motor sliding seat 6 drives the first motor 5 to move. The power wheel 401 moves with the first motor 5 until the power wheel 401 and the two auxiliary wheels 402 simultaneously hold the magnetic ring against the magnetic ring to complete the loading and positioning of the magnetic ring. The outer layers of the power wheel 401 and the two auxiliary wheels 402 are both provided with rubber to increase friction. When the power wheel 401 rotates, the magnetic ring is driven to rotate by friction, that is, the first motor 5 applies pressure to the magnetic ring to position it and drives the magnetic ring to rotate.

[0038] The wire loading mechanism is connected to the control system circuit. The wire loading mechanism includes a large electric push rod 21, a rotating module 22, and a wire feeder 20. The large electric push rod 21 is installed on the wire loading device bracket 3, and the rotating module 22 is installed on the large electric push rod 21. The wire feeder 20 is arranged at one end of the rotating module 22 away from the large electric push rod 21. The large electric push rod 21 drives the wire feeder 20 to move in the direction close to or away from the L-shaped plate bracket 2. The rotating module 22 drives the wire feeder 20 to rotate around the axis. The wire feeder 20 transmits the winding wire. Under the control of the control system, the moving module controls the L-shaped plate The bracket 2 and the wire loader bracket 3 start to move, so that the wire feeder 20 moves closer to the electric clamp 12, and the wire feeder 20 sends the winding wire forward for a certain length. The control system clamps the head of the winding wire through the electric clamp 12, and the moving module drives the wire loader bracket 3 to move, so that the wire feeder 20 approaches the inner wire groove of the winding ring 14, squeezes the winding wire through the inner stopper 18 and pushes it into the inner wire groove. As the winding ring 14 rotates, the wire feeder 20 sends out the winding wire, and the winding wire is slowly buried in the inner wire groove. The inner stopper 18 prevents the winding wire buried in the inner wire groove from being pulled away;

[0039] As the inner wire groove is filled, the wire winding ring 14 stops rotating, and the rotating module 22 drives the wire feeder 20 to rotate so that the winding wire bypasses the reversing roller 16. The control system controls the wire winding ring 14 to rotate in the opposite direction, and the winding wire is squeezed through the outer baffle 17 and pushed into the outer wire groove 15. The wire winding ring 14 rotates while the wire feeder 20 feeds the winding wire until the outer wire groove 15 is also filled with the winding wire. The winding wire is cut off inside the wire feeder 20 by an electric shear, and the control system uses the moving module to drive the L-shaped plate bracket 2 and the wire loader bracket 3 to return to their positions.

[0040] The winding mechanism includes an annular housing 8 and a winding ring 14. The annular housing 8 and the winding ring 14 are both provided with notches. The winding ring 14 is slidably installed in the annular housing 8. An electric clamp 12 is provided at a position close to the notch on one side of the annular housing 8. The upper and lower ends of the annular housing 8 are provided with closed brackets. A transmission wheel 13 is rotatably installed inside each closed bracket. The transmission wheel 13 contacts the outer contour of the winding ring 14. An outer wire groove 15 is provided on the outer ring of the winding ring 14. An inner wire groove is provided on the inner ring of the winding ring 14. A reversing roller is rotatably installed at one end of the winding ring 14. 16, the reversing roller 16 is connected with the outer wire groove 15 and the inner wire groove, the outer side of the outer wire groove 15 is covered with an outer barrier 17, and the outer side of the inner wire groove is covered with an inner barrier 18. The outer barrier 17 is composed of two barrier skins with trapezoidal cross-sections. The inner barrier 18 has the same structure as the outer barrier 17. After the winding wire fills the inner wire groove, it bypasses the reversing roller 16 and continues to fill the outer wire groove 15. The trapezoidal inclined surfaces of the inner barrier 18 and the outer barrier 17 make it easier for the winding wire to be embedded in the inner wire groove and the outer wire groove 15. The inner barrier 18 and the outer barrier 17 also prevent the winding wire from escaping from the inner wire groove and the outer wire groove 15.

[0041] A plurality of pairs of convergence rollers 19 are arranged inside the winding ring 14, and the plurality of pairs of convergence rollers 19 are respectively arranged on both sides of the outer wire groove 15 and on both sides of the inner wire groove, and the plurality of pairs of convergence rollers 19 are evenly arranged along the outer wire groove 15 or the inner wire groove, and a coil spring (not shown in the figure) is arranged at the transition between each convergence roller 19 and the winding ring 14, and the two transmission wheels 13 are coaxially connected to a driven sprocket 102, and a second motor 9 is installed on the L-shaped plate bracket 2, and a driving sprocket 101 is installed on the second motor 9, and the driving sprocket 101 is located between the two driven sprockets 102, and the driving sprocket 101 A chain 11 is connected between the two driven sprockets 102, and the second motor 9 drives the driving sprocket 101 to rotate. The driving sprocket 101 drives the two driven sprockets 102 to rotate through the chain 11. The two driven sprockets 102 drive the two transmission wheels 13 to rotate. The two transmission wheels 13 drive the winding ring 14 to rotate in the annular housing 8 through friction. Even if one of the transmission wheels 13 is located at the gap of the winding ring 14, the other transmission wheel 13 keeps in contact with the winding ring 14, driving the winding ring 14 to rotate, that is, the second motor 9 drives the winding ring 14 to rotate forward or reverse.

[0042] As the end of the winding wire is clamped by the electric clamp 12, when the winding ring 14 starts to rotate, the winding wire begins to be wound around the magnetic ring. At this time, the first motor 5 also drives the magnetic ring to rotate. It is blocked by the inner and outer retaining skins 18 and 17, and the winding wire can only be drawn out from the position of the notch of the winding ring 14. After the winding ring 14 rotates several times, sufficient friction is generated between the winding wire and the magnetic ring so that it will not loosen. The control system then controls the electric clamp 12 to loosen the wire end. As the notch of the winding ring 14 sometimes approaches the magnetic ring and sometimes moves away from the magnetic ring during the rotation, more winding wire is drawn out from the outer wire groove 15 and the inner wire groove when the notch moves away from the magnetic ring. When the notch approaches the magnetic ring again, it will cause the winding wire to loosen, affecting the uniformity of winding. Therefore, both sides of the outer wire groove 15 and the inner wire groove are provided with convergence rollers 1 9. There is friction between the gathering roller 19 and the surface of the embedded winding wire. When the winding wire is pulled out, the gathering roller 19 will also be driven to rotate. When the gathering roller 19 rotates, it relies on the coil spring to accumulate reverse torque. When the winding wire becomes loose, the coil spring drives the gathering roller 19 to reverse, and the winding wire is retracted into the outer wire groove 15 or the inner wire groove through friction, so that the winding wire is always tightened during the winding process, so that the winding of the winding wire on the magnetic ring is more uniform. After the winding is completed, the loading and unloading robot arm removes the magnetic ring inductor and proceeds to the next process. By setting a winding ring 14 larger than the magnetic ring, the winding wire of sufficient length is set in the winding ring 14 in advance, and then continuously wound on the magnetic ring. Compared with intermittent winding equipment, it is faster, the winding is more uniform and beautiful, and the winding efficiency is higher.

[0043] The working principle of the present invention is as follows: the loading and unloading robotic arms clamp the magnetic ring and move it to the magnetic ring positioning platform 1, the small electric push rod 7 pushes the motor sliding seat 6 to move, the motor sliding seat 6 drives the first motor 5 to move, and the power wheel 401 moves with the first motor 5 until the power wheel 401 and the two auxiliary wheels 402 simultaneously hold the magnetic ring against the material loading and positioning of the magnetic ring. The outer layers of the power wheel 401 and the two auxiliary wheels 402 are provided with rubber to increase friction. When the power wheel 401 rotates, the magnetic ring is driven to rotate by friction, that is, the first motor 5 applies pressure to the magnetic ring to position it and drives the magnetic ring to rotate.

[0044] The large electric push rod 21 drives the wire feeder 20 to move in the direction of approaching or moving away from the L-shaped plate bracket 2, and the rotating module 22 drives the wire feeder 20 to rotate around the axis, and the wire feeder 20 transmits the winding wire. Under the control of the control system, the moving module controls the L-shaped plate bracket 2 and the wire loader bracket 3 to start moving, so that the wire feeder 20 moves close to the electric clamp 12, and the wire feeder 20 sends the winding wire forward for a certain length. The control system clamps the head of the winding wire through the electric clamp 12, and the moving module drives the wire loader bracket 3 to move, so that the wire feeder 20 approaches the inner wire groove of the winding ring 14, squeezes the winding wire through the inner stopper 18 and pushes it into the inner wire groove. As the winding ring 14 rotates, the wire feeder 20 sends out the winding wire, and the winding wire is slowly buried in the inner wire groove. The inner stopper 18 prevents the winding wire buried in the inner wire groove from being pulled away;

[0045] As the inner wire groove is filled, the wire winding ring 14 stops rotating, and the rotating module 22 drives the wire feeder 20 to rotate so that the winding wire bypasses the reversing roller 16. The control system controls the wire winding ring 14 to rotate in the opposite direction, and the winding wire is squeezed through the outer baffle 17 and pushed into the outer wire groove 15. The wire winding ring 14 rotates while the wire feeder 20 feeds the winding wire until the outer wire groove 15 is also filled with the winding wire. The winding wire is cut off inside the wire feeder 20 by an electric shear, and the control system uses the moving module to drive the L-shaped plate bracket 2 and the wire loader bracket 3 to return to their positions.

[0046] After the winding wire fills the inner wire groove, it bypasses the commutation roller 16 and continues to fill the outer wire groove 15. The trapezoidal inclined surfaces of the inner and outer retaining skins 18 and 17 make it easier for the winding wire to be embedded in the inner and outer wire grooves 15. The inner and outer retaining skins 18 and 17 also prevent the winding wire from escaping from the inner and outer wire grooves 15.

[0047] The second motor 9 drives the active sprocket 101 to rotate, and the active sprocket 101 drives the two driven sprockets 102 to rotate through the chain 11. The two driven sprockets 102 drive the two transmission wheels 13 to rotate, and the two transmission wheels 13 drive the wire winding ring 14 to rotate in the annular housing 8 through friction. Even if one of the transmission wheels 13 is located at the gap of the wire winding ring 14, the other transmission wheel 13 keeps in contact with the wire winding ring 14, driving the wire winding ring 14 to rotate, that is, the wire winding ring 14 is driven by the second motor 9 to rotate forward or reverse.

[0048] As the end of the winding wire is clamped by the electric clamp 12, when the winding ring 14 starts to rotate, the winding wire begins to be wound around the magnetic ring. At this time, the first motor 5 also drives the magnetic ring to rotate. It is blocked by the inner and outer retaining skins 18 and 17, and the winding wire can only be drawn out from the position of the notch of the winding ring 14. After the winding ring 14 rotates several times, sufficient friction is generated between the winding wire and the magnetic ring so that it will not loosen. The control system then controls the electric clamp 12 to loosen the wire end. As the notch of the winding ring 14 sometimes approaches the magnetic ring and sometimes moves away from the magnetic ring during the rotation, more winding wire is drawn out from the outer wire groove 15 and the inner wire groove when the notch moves away from the magnetic ring. When the notch approaches the magnetic ring again, it will cause the winding wire to loosen, affecting the uniformity of winding. Therefore, both sides of the outer wire groove 15 and the inner wire groove are provided with convergence rollers 1 9. There is friction between the gathering roller 19 and the surface of the embedded winding wire. When the winding wire is pulled out, the gathering roller 19 will also be driven to rotate. When the gathering roller 19 rotates, it relies on the coil spring to accumulate reverse torque. When the winding wire becomes loose, the coil spring drives the gathering roller 19 to reverse, and the winding wire is retracted into the outer wire groove 15 or the inner wire groove through friction, so that the winding wire is always tightened during the winding process, so that the winding of the winding wire on the magnetic ring is more uniform. After the winding is completed, the loading and unloading robot arm removes the magnetic ring inductor and proceeds to the next process. By setting a winding ring 14 larger than the magnetic ring, the winding wire of sufficient length is set in the winding ring 14 in advance, and then continuously wound on the magnetic ring. Compared with intermittent winding equipment, it is faster, the winding is more uniform and beautiful, and the winding efficiency is higher.
