In addition, the existing automatic winding machine also needs to manually fix the end of the wire to the insulating tube during winding, and manually cut the wire after the winding operation is completed, resulting in low processing efficiency.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention is provided with a clamping mechanism, which clamps the end of the insulating tube by four clamping wheels, and then drives one of the clamping wheels to rotate to drive the insulating tube to rotate, so that the wire is wound around the outside of the insulating tube. For ordinary winding inductors, the insulating tube can be clamped directly. For common mode inductors with magnetic rings, the magnetic rings of the common mode inductors can be placed on the inner side of the clamping plate of the U-shaped structure, so that the four clamping wheels can still be moved to the outer side of the end of the insulating tube for clamping. In this way, automatic winding operation can be realized for both ordinary winding inductors and common mode inductors, and the practicality is high.

[0018] (2) As described above, when clamping the end of the insulating tube, the two slides are moved toward the middle by rotating the double-headed screw, so that the horizontal through grooves of the two slides push the ends of the four clamping wheels, so that the four clamping wheels slide along the four inclined through grooves on the clamping plate respectively, so that the four clamping wheels move toward the middle at the same time to clamp the end of the insulating tube. The operation is simple and efficient.

[0019] (3) The present invention is provided with a rotating shaft, a groove and a protrusion. When the rotating shaft is rotated, the groove drives the two second bevel gears to rotate respectively through the two protrusions, thereby driving the two double-headed screws to rotate at the same time through meshing transmission, thereby realizing that one driving device drives the two clamping components to clamp synchronously, reducing the equipment manufacturing cost and improving the clamping efficiency; in addition, when the moving slide drives the corresponding clamping plate to move to clamp insulating tubes of different lengths, the slide simultaneously drives the corresponding second bevel gear and the protrusion to slide in the groove, thereby realizing synchronous clamping of the two clamping structures for insulating tubes of different lengths.

[0020] (4) The present invention is provided with an actuator, which pushes out the telescopic end of the third electric push rod to make the ends of the two first connecting rods move in the section of the L-shaped guide groove perpendicular to the third electric push rod, so that the ends of the two first connecting rods drive the two clamping rods to approach each other through the slide groove to clamp the winding, and then the wire is bent by the rotation of the rotating seat, and then the first electric push rod and the second electric push rod are extended and retracted to make the rotating seat drive the two clamping rods and the wire to move into the slot at the end of the insulating tube, and the bent end of the wire is located outside the insulating tube, and then the insulating tube can be rotated to make the winding be wound around the insulating tube in sequence, so as to achieve the fixation of the wire end and realize the automatic winding operation, and the processing efficiency is high.

[0021] (5) The present invention is provided with an L-shaped pull rod, a second connecting rod and a cutter. After the winding operation is completed, the rotating seat is rotated so that the two clamping rods are arranged horizontally and the cutter is located at the lower side of the clamping rod. Then the third electric push rod pushes out the telescopic end so that the two first connecting rods drive the two clamping rods to clamp the wire through the slide groove, and the wire is moved to the slot at the other end of the insulating tube. Then the third electric push rod continues to push out the telescopic end. The presence of the rubber pad enables the ends of the two first connecting rods to move to the section of the L-shaped guide groove parallel to the third electric push rod. Then the ends of the two first connecting rods slide along the section of the L-shaped guide groove parallel to the third electric push rod and move in the slide groove at the same time, thereby pulling the two L-shaped pull rods so that the two second connecting rods respectively push the two cutters closer to each other, and finally cut the wire. At this time, the two clamping rods still clamp the ends of the wire. After replacing another insulating tube, the above-mentioned wire end fixing operation can be repeated to fix the wire end to the end of another insulating tube, so as to achieve continuous processing and improve processing efficiency.

DETAILED DESCRIPTION

[0034] 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.

[0035] See also Figure 1-Figure 11 As shown, the present invention provides the following technical solutions:

[0036] An automatic winding machine for inductor processing, comprising a frame 1 and two fixed seats 2 fixed on the frame 1, a wire assembly is slidably arranged between the two fixed seats 2, a wire feeding assembly is arranged on one side of the frame 1, a slide seat 21 is slidably connected to the frame 1, and two clamping assemblies arranged opposite to each other are arranged on the frame 1 and the slide seat 21;

[0037] The clamping assembly includes a U-shaped clamping plate 22 and two slides 20 symmetrically and slidably connected to one side of the clamping plate 22. The clamping plate 22 is provided with four inclined through grooves in a circumferential array with their ends pointing to the center. A double-headed screw 19 is rotatably connected to one side of the clamping plate 22. The two slides 20 are respectively screwed together at both ends of the double-headed screw 19. Horizontal through grooves are provided on the two slides 20. Clamping wheels 26 are slidably connected in the four inclined through grooves, and the ends of the two groups of clamping wheels 26 located on the upper and lower sides are respectively slidably fitted in the two horizontal through grooves.

[0038] Based on the above disclosed structure, when performing the automatic winding operation of the inductor:

[0039] First, move the slide 21 on the frame 1 so that the distance between the two groups of clamping wheels 26 in the two clamping assemblies corresponds to the length of the insulating tube, so that the two groups of clamping wheels 26 can clamp the two ends of the insulating tube respectively. For ordinary winding inductors, the insulating tube can be directly placed between the two clamping plates 22, and the two ends of the insulating tube are respectively located between the two groups of clamping wheels 26. For common mode inductors with magnetic rings, the magnetic rings can be extended into the U-shaped grooves of the two clamping plates 22, and the insulating tube outside the magnetic rings is located between the two clamping plates 22. The magnetic rings can be clamped between the clamping plates 22. The plate 22 moves left and right in the U-shaped groove, so that the two ends of the insulating tube can be moved between the two groups of clamping wheels 26 respectively, and then the two double-headed screws 19 are rotated respectively, so that the two groups of slides 20 are moved toward the middle, so that the horizontal through grooves on the two groups of slides 20 push the ends of the corresponding clamping wheels 26 respectively, so that the clamping wheels 26 slide along the inclined through grooves on the clamping plate 22, so that the four clamping wheels 26 in each group are moved toward the center of the clamping plate 22, so that the two groups of clamping wheels 26 clamp the two ends of the two insulating tubes respectively;

[0040] Then, the wire is pulled out from the wire feeding assembly and passes through the wire assembly, and the end of the wire is fixed in the slot at the end of the insulating tube. Preferably, a movable seat is slidably connected to the outside of one of the slides 20, and a driving motor is fixed on the movable seat. The output shaft of the driving motor is fixedly connected to the rotating shaft of one of the clamping wheels 26, so that the corresponding clamping wheel 26 is driven to rotate by the driving motor. The friction between the clamping wheel 26 and the end of the insulating tube causes the insulating tube to rotate between the two groups of clamping wheels 26, so that the wire is wound around the outside of the insulating tube by the rotation of the insulating tube, and the wire assembly is moved between the two fixed seats to make the wire evenly wound around the outside of the insulating tube, thereby realizing the automatic winding operation of the inductor.

[0041] Preferably, a second screw rod 32 that is screwed through the slide 21 is rotatably provided on the frame 1, a rotating shaft 33 is rotatably provided on the frame 1, and a second bevel gear 38 is rotatably provided on both the frame 1 and the slide 21. A first bevel gear 37 is coaxially fixed to the bottom of the two double-headed screws 19, and the two first bevel gears 37 are respectively meshed and connected with the two second bevel gears 38, and a protrusion 39 is fixedly installed on the inner side of the two second bevel gears 38. A groove 34 is provided on the rotating shaft 33, and the two protrusions 39 are slidably fitted in the groove 34. Based on this, regarding the driving rotation of the two double-headed screws 19, the motor drives the rotating shaft 33 to rotate, and the groove 34 pushes the two second bevel gears 38 to rotate through the two protrusions 39, so that the two meshing first bevel gears 37 rotate, and then the two first bevel gears 37 drive the corresponding coaxially fixed double-headed screws 19 to rotate, so as to realize the synchronous clamping operation of the two clamping structures, and only use one driving device to reduce the equipment manufacturing cost; in addition, regarding the movement of the slide 21 on the frame 1, the motor drives the second screw 32 to rotate, so that the screw-connected slide 21 moves along the second screw 32 on the frame 1, thereby changing the distance between the two groups of clamping wheels 26 on the two clamping plates 22, so that when clamping insulating tubes of different lengths, when the slide 21 moves, the slide 21 drives the corresponding second bevel gear 38 and the protrusion 39 to slide in the groove 34 on the rotating shaft 33, so that the clamping operation of insulating tubes of different lengths can achieve synchronous clamping of both ends of the insulating tube.

[0042] In addition, when clamping the insulating tube outside the common-mode inductor magnetic ring, the magnetic ring of the common-mode inductor can also be supported, which can prevent the magnetic ring from tilting up due to its own gravity and colliding with the inner wall of the insulating tube, affecting the rotation of the insulating tube. Preferably, a second screw 24 is provided on the frame 1 for sliding through, and a support plate 25 is fixedly installed on the top of the second screw 24. Two adjusting nuts 23 are screwed and connected to the second screw 24, and the two adjusting nuts 23 are respectively located on the upper and lower sides of the frame 1. Based on this, by rotating the two adjusting nuts 23 respectively to adjust the length of the second screw 24 extending above the frame 1, the height of the support plate 25 is adjusted, and one end of the magnetic ring sleeved with the insulating tube is supported in the U-shaped groove of the two clamping plates 22, and one end of the outer side of the magnetic ring is supported on the support plate 25, so that the magnetic ring is placed in parallel, reducing the force between the magnetic ring and the inner wall of the insulating tube, and avoiding affecting the rotation of the insulating tube.

[0043] As mentioned above, regarding the wire assembly and the wire feeding assembly, it is preferred to have the following structure:

[0044] The wire assembly includes a slide plate 8 and a plurality of first wire wheels 7 rotatably connected to the slide plate 8, a guide seat 9 is fixedly mounted on the slide plate 8, a guide rod 5 is fixedly mounted on the guide seat 9, a guide wheel 4 is rotatably connected to one side of the guide rod 5, and the guide wheel 4 is located above the two clamping assemblies;

[0045] A guide rod 10 is fixedly installed between the two fixed seats 2 and slides through the slide plate 8. A first screw rod 3 is rotatably provided between the two fixed seats 2 and screwed through the slide plate 8.

[0046] The wire feeding assembly includes a discharge seat 18 fixed to one side of the frame 1 and a wire taking plate 15 fixed to one side of one of the fixed seats 2. One side of the wire taking plate 15 is located directly above the discharge seat 18 and is rotatably connected to a second wire pulley 28. A driving wheel 29 is rotatably provided in the middle of the wire taking plate 15. A first screw 16 with an end facing the driving wheel 29 is screwed through the wire taking plate 15. A second slider 17 slidably connected to the wire taking plate 15 is rotatably connected to the end of the first screw 16. A clamping wheel 30 is rotatably connected inside the second slider 17.

[0047] A slide rod 13 slides through the top of the wire taking plate 15, and a first slider 12 is fixedly installed at the bottom of the slide rod 13. A tensioning wheel 27 is rotatably connected to the first slider 12. A spring 14 is fixedly connected between the top of the first slider 12 and the wire taking plate 15, and the spring 14 is sleeved on the outside of the slide rod 13.

[0048] As can be seen from the above, the wire material is placed on the discharge seat 18, the wire end is pulled upward, and the wire is passed through the second wire wheel 28, the driving wheel 29, the tensioning wheel 27, the plurality of first wire wheels 7 and the guide wheel 4 in sequence, and finally the wire end is fixed in the card slot at the end of the insulating tube, and then the first screw 16 on the wire taking plate 15 is rotated, so that the end of the first screw 16 pushes the second slider 17 to drive the clamping wheel 30 to slide close to the driving wheel 29, so that the clamping wheel 30 and the driving wheel 29 clamp the wire, and then the driving wheel 29 is driven at the same time. The moving wheel 29 and one of the clamping wheels 26 rotate, and the clamping wheel 30 and the driving wheel 29 use the friction between the wire and the wire to continuously extract the wire from the feeding seat 18. At the same time, the clamping wheel 26 drives the rotation of the insulating tube to wind the wire around the insulating tube in sequence. At the same time, the first screw rod 3 is controlled to rotate, so that the slide plate 8 moves along the guide rod 10 and the first screw rod 3, thereby driving the guide wheel 4 to move from one end to the other end above the insulating tube through the guide seat 9 and the guide rod 5, so as to realize that the wire is automatically and evenly wound around the outside of the insulating tube in sequence.

[0049] In addition, the second wire wheel 28 is located directly above the feeding seat 18, so that the wire is always pulled out at a smaller angle, avoiding the wire from being broken due to excessive inclination angle when being pulled out; when the slide plate 8 moves, the distance between the first wire wheel 7 and the driving wheel 29 on the slide plate 8 gradually increases, and the setting of the tensioning wheel 27 can avoid the wire from being broken. When the wire presses the tensioning wheel 27 downward, the first slider 12 drives the slide bar 13 to slide downward in the wire taking plate 15, and at the same time, the first slider 12 stretches the spring 14 downward, thereby avoiding the wire from being broken when the slide plate 8 moves. In addition, when the slide plate 8 approaches the driving wheel 29, the elastic force of the spring 14 will also keep the wire taut at all times, avoiding the wire from detaching from the first wire wheel 7 and affecting the use of the equipment; multiple first wire wheels 7 are used to change the stretching direction of the wire, so that the wire is perpendicular to the axial direction of the insulating tube before winding, which is convenient for winding.

[0050] In addition, with regard to fixing the end of the wire in the slot at the end of the insulating tube, it is preferred to have the following structure:

[0051] The bottom end of the slide plate 8 is rotatably connected to a first electric push rod 6, a second electric push rod 11 is rotatably connected between one side of the sleeve of the first electric push rod 6 and the slide plate 8, and an actuator for clamping and shearing the wire is provided at the telescopic end of the first electric push rod 6;

[0052] The actuator includes a rotating seat 31 rotatably arranged at the end of the first electric push rod 6 and two clamping rods 35 symmetrically slidably connected to the rotating seat 31, and the two clamping rods 35 are both located in an eccentric position, and rubber pads are fixed to the clamping sides of the two clamping rods 35. One side of the two clamping rods 35 is provided with a slide groove 44. The rotation axis of the rotating seat 31 is located directly below the first wire wheel 7. Two L-shaped guide grooves 45 are symmetrically provided on the rotating seat 31. A third electric push rod 41 is fixed on the rotating seat 31. The first connecting rod 40 is rotatably connected to both sides of the telescopic end of the third electric push rod 41. The ends of the two first connecting rods 40 are respectively slidably fitted in the two slide grooves 44, and the ends of the two first connecting rods 40 are simultaneously and respectively slidably fitted in the two L-shaped guide grooves 45.

[0053] As can be seen from the above, the rotating seat 31 is driven to rotate so that the two clamping rods 35 are relatively horizontally arranged. At this time, the guide wheel 4 is located between the two clamping rods 35 in the horizontal direction, so that the end of the wire is passed around the guide wheel 4 and pulled out between the two clamping rods 35, and then the third electric push rod 41 is started to push out the telescopic end so that the ends of the two first connecting rods 40 move in the section of the L-shaped guide groove 45 perpendicular to the third electric push rod 41, so that the ends of the two first connecting rods 40 pull the slide groove 44 to drive the two clamping rods 35 to approach each other, thereby clamping the wire, and then the rotating seat 31 is driven to rotate to bend the end of the wire, and at the same time, the end of the wire is offset to the bottom of the guide wheel 4, and then the second electric push rod 11 pushes out the telescopic end so that the first electric push rod 6 drives the rotating seat 31 and the two clamping rods 35 move the end of the wire to the same height as the insulating tube slot, and then the first electric push rod 6 pushes out the telescopic end, so that the rotating seat 31 and the two clamping rods 35 drive the wire to insert into the slot of the insulating tube. At this time, the wire between the guide wheel 4 and the insulating tube and the bent end of the wire are respectively located on both sides of the slot, and then the third electric push rod 41 retracts the telescopic end so that the ends of the two first connecting rods 40 push the slide slot 44 to drive the two clamping rods 35 to move to both sides to release the clamping of the wire, so that the first electric push rod 6 retracts the telescopic end, so that the rotating seat 31 and the two clamping rods 35 are away from the insulating tube, and then the insulating tube can be rotated so that the wire is wound around the insulating tube in turn, thereby realizing automatic fixation of the wire end and automatic winding.

[0054] In addition, for automatic cutting of the wire after the winding is completed, it is preferred that the outer sides of the two clamping rods 35 are slidably connected with a cutter 36, and the ends of the two first connecting rods 40 that slide and fit in the slide groove 44 are rotatably connected with an L-shaped pull rod 42, and the ends of the two L-shaped pull rods 42 are rotatably connected with the two cutters 36. Based on this, after the winding is completed, the rotating seat 31 is driven to rotate so that when the two clamping rods 35 are horizontally arranged and the cutter 36 is located below the clamping rod 35, the first electric push rod 6 pushes out the telescopic end, so that the rotating seat 31 drives the two clamping rods 35 to move to both sides of the wire, and then the third electric push rod 41 pushes out the telescopic end to move the ends of the two first connecting rods 40 in the section of the L-shaped guide groove 45 perpendicular to the third electric push rod 41, so that the ends of the two first connecting rods 40 pull the slide groove 44 to drive the two clamping rods 35 to move closer to each other to clamp the wire, and then the rotating seat 31 is driven to rotate to bend the wire, and through the telescopic movement of the above-mentioned first electric push rod 6 and the second electric push rod 11, the wire is moved to the insulation. The clamping rod 35 and the cutter 36 are located outside the end of the insulating tube, and then the third electric push rod 41 continues to push out the telescopic end. The presence of the rubber pad enables the ends of the two first connecting rods 40 to move to the section of the L-shaped guide groove 45 parallel to the third electric push rod 41, and then the ends of the two first connecting rods 40 slide along the section of the L-shaped guide groove 45 parallel to the third electric push rod 41, and at the same time, the ends of the two first connecting rods 40 move in the slide groove 44, so that the ends of the two first connecting rods 40 respectively pull the two L-shaped pull rods 42 so that the two second connecting rods 43 respectively push the two cutters 36 closer to each other, and finally the two cutters 36 cut the wires, thereby realizing automatic cutting of the wires.

[0055] In addition, at this time, the two clamping rods 35 are still clamping the ends of the wires. After the clamping assembly is replaced to clamp another insulating tube, the above-mentioned wire end fixing operation can be repeated to fix the wire ends to the ends of another insulating tube to achieve continuous processing and improve processing efficiency.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
