DETAILED DESCRIPTION

[0025] The technical scheme of the present application will be described in further detail below with reference to the drawings, but the protection scope of the present application is not limited to the following description.

[0026] Example 1

[0027] As Figures 1 to 7As shown, an automatic inductor winding system with screw advance mechanism includes a fixed base 1, on which a rotating winding disc 2 is rotatably mounted. Several winding assemblies are evenly distributed along the circumference of the rotating winding disc 2. Each winding assembly includes a precision screw 3, a screw-in sleeve 4, and a negative pressure tube 5. The axis of the precision screw 3 is horizontally positioned. The screw-in sleeve 4 is threaded onto the precision screw 3. The end of the screw-in sleeve 4 away from the fixed base 1 is connected to the negative pressure tube 5. The negative pressure tube 5 and the screw-in sleeve 4 are coaxially arranged. The system also includes a feeding arm assembly. The system comprises a core rod, a screw drive assembly, and a wire feeding assembly. The wire feeding assembly and the screw drive assembly are arranged radially spaced along the rotating winding disc 2. The feeding arm assembly and the wire feeding assembly are arranged circumferentially spaced along the rotating winding disc 2. The feeding arm assembly is used to transport the core rod to the negative pressure tube 5. The wire feeding assembly includes a wire reel 6, which is mounted on a fixed base 1. The axis of the wire reel 6 is horizontally set, and the wire reel 6 is used to feed the wire to the core rod. The screw drive assembly is used to drive the screw-in sleeve 4 to perform a screw-in motion on the precision screw 3. The rotation of the winding disc 2... The rotation causes multiple winding assemblies to sequentially move to the working position of the feeding arm assembly. The feeding arm assembly feeds the core column onto the negative pressure tube 5. The negative pressure tube 5 clamps the core column using negative pressure. The winding assembly clamping the core column rotates to the working position of the unloading assembly. The screw-in drive assembly drives the screw-in sleeve 4 to rotate, while the wire reel 6 of the unloading assembly rotates to release the wire. Since the screw-in sleeve 4 is threaded onto the precision screw 3, the screw-in drive assembly drives the screw-in sleeve 4 to perform a screw-in motion, so that the screw-in sleeve 4 is on the precision screw 3. The screw advances, integrating the linear and rotary motions of the winding onto the core post. This causes the core post to reciprocate along its own axis, tightly winding the conductor around it and achieving high-precision automated winding of the inductor. In practice, a precision screw 3 with a corresponding pitch is installed according to the winding precision requirements. The screw advance sleeve 4 rotates one revolution, moving a distance of one pitch. The precision screw 3 has high precision, thus enabling high-precision winding. Furthermore, by replacing the precision screw 3, different winding precision requirements can be accommodated.

[0028] Furthermore, the side wall of the fixed base 1 is equipped with a wire-cutting robot arm and a wire-winding robot arm. The wire-feeding assembly is located between the screw-in drive assembly and the wire-cutting robot arm, and between the feeding arm assembly and the wire-winding robot arm. The wire-feeding assembly also includes a guide tube 50, which is installed vertically. The wire of the wire spool 6 passes through the guide tube 50. A winding motor is installed on the wire spool 6 to drive the winding shaft on the wire spool 6 to rotate. Each winding assembly sequentially passes through the core post for feeding and screw-in winding. After winding, the wire is cut by the wire-cutting robot arm. A starting scissor is installed at the execution end of the robot arm to complete the wire-cutting operation. At this time, the winding assembly carries the core post to the working position of the winding robot arm. The winding robot arm winds the two ends of the wire wound on the core post onto the wire post of the core post to complete the entire winding action. Finally, it rotates to the next station for unloading. This cycle realizes the automatic winding of the inductor. A starting gripper is installed at the execution end of the robot arm to hold the end of the wire and wind it onto the wire post.

[0029] Example 2

[0030] Based on Example 1, such as Figures 1 to 4 As shown, the screw-in sleeve 4 includes a hollow threaded tube 7 and a large-diameter tube 8. One end of the threaded tube 7 is threaded onto the precision screw 3, and the other end is coaxially connected to the large-diameter tube 8. The end of the large-diameter tube 8 furthest from the threaded tube 7 is coaxially connected to the negative pressure tube 5. The inner diameter of the large-diameter tube 8 is larger than the outer diameter of the threaded tube 7. A right limiting plate 9 is provided inside the large-diameter tube 8. One end of the precision screw 3 is fixedly connected to the right limiting plate 9. The diameter of the right limiting plate 9 is larger than the inner diameter of the threaded tube 7. A left limiting plate 10 is fixedly sleeved on the precision screw 3. The threaded tube 7 is located between the large-diameter tube 8 and the left limiting plate 10. The movement range of the screw-in sleeve 4 is controlled by the right limiting plate 9 and the left limiting plate 10. As long as the winding range of the core column is smaller than the movement range of the screw-in sleeve 4, the automatic winding action can be completed by this winding system. The screw-in sleeve 4 is set in a stepped shape to facilitate the installation of the right limiting plate 9 inside the large-diameter tube 8 and prevent the screw-in sleeve 4 from falling off the precision screw 3.

[0031] Example 3

[0032] Based on Example 2, such as Figures 1 to 5As shown, a wire pressing assembly is provided on the side wall of the large-diameter pipe 8. The wire pressing assembly includes a horizontal long rod 13, a vertical connecting rod 14, a horizontal short rod 15, and a driving vertical rod 16. The two ends of the vertical connecting rod 14 are connected to the horizontal long rod 13 and the horizontal short rod 15 respectively in a Z-shape. The vertical connecting rod 14 is located between the horizontal short rod 15 and the negative pressure pipe 5. An installation groove 11 is opened on the side wall of the large-diameter pipe 8. A spring 12 is installed in the installation groove 11. One end of the driving vertical rod 16 is slidably adapted to the installation groove 11 and connected to the spring 12. The other end of the driving vertical rod 16 is connected to the horizontal long rod 13. A first electromagnet 17 is embedded in the side wall of the large-diameter pipe 8. A permanent magnet 18 is provided on the end face of the horizontal long rod 13 near the first electromagnet 17. When the first electromagnet 17 is energized, it generates a magnetism opposite to the magnetic pole of the permanent magnet 18. Under normal conditions, when the first electromagnet 17 is de-energized, the horizontal... The short rod 15 is located on one side of the negative pressure pipe 5. A gap is formed between the horizontal short rod 15 and the negative pressure pipe 5 for the wire to pass through. The wire released by the wire feeding assembly passes through this gap. Then, the first electromagnet 17 is energized, which attracts the permanent magnet 18, causing the drive rod 16 to compress the spring 12 and move. The drive rod 16 drives the horizontal short rod 15 to move closer to the core column, thereby pressing the end of the wire against the side wall of the core column. This allows the screw-in sleeve 4 to smoothly wind the wire onto the core column during its screw-in motion. It should be noted that the wire pressing position of the horizontal short rod 15 is the winding end point of the core column. The subsequent winding area will not cover the winding end point, so that the wire will not be wrapped around the horizontal short rod 15. After the winding is completed, the first electromagnet 17 is de-energized, causing the horizontal short rod 15 to release the wire, allowing the wound core column to be smoothly unloaded. In practice, since the core column is I-shaped, the horizontal short rod 15 can bypass the large-diameter end of the core column and reach the small-diameter area in the middle of the core column to perform the wire pressing operation under the action of the horizontal long rod 13 and the vertical connecting rod 14.

[0033] Example 4

[0034] Based on Embodiment 3, the screw-in drive assembly includes a horizontal lifting seat 27, a clamping assembly, and a lifting cylinder 28. The cylinder body of the lifting cylinder 28 is vertically mounted on the fixed base 1. The telescopic shaft of the lifting cylinder 28 is connected to the horizontal lifting seat 27. The clamping assembly includes a V-shaped slide 29. The top surface of the horizontal lifting seat 27 has a groove 30 along the axial direction of the screw-in sleeve 4. A slider 31 is fixed at the bottom of the V-shaped slide 29. The slider 31 slides within the groove 30. Two rubber drive wheels 32 are arranged radially opposite each other within the V-shaped slide 29 along the radial direction of the screw-in sleeve 4. The rubber drive wheels 32 are rotatably connected to the V-shaped slide 29 via a drive shaft. A drive motor 33 is mounted on the V-shaped slide 29. The output shaft of the drive motor 33 is connected to the drive shaft. When the winding assembly clamps the core column... When the screw-in drive assembly is in its working position, the lifting cylinder 28 drives the V-shaped slide 29 to move upward, causing the two rubber drive wheels 32 to contact the large-diameter tube 8 of the screw-in sleeve 4. The drive motor 33 drives the rubber drive wheels 32 to rotate, which in turn drives the screw-in sleeve 4 to rotate. The screw-in sleeve 4 performs a screw-in motion under the action of the precision screw 3. To avoid interference between the screw-in sleeve 4 and the rubber drive wheels 32, the V-shaped slide 29 is set to a sliding type. The screw-in sleeve 4 will drive the V-shaped slide 29 to move on the horizontal lifting seat 27, so that the screw-in sleeve 4 can perform a normal screw-in motion to complete the winding action. The drive motor 33 drives the rubber drive wheels 32 to rotate forward and backward, so that the screw-in sleeve 4 performs a reciprocating screw-in motion, realizing the automatic winding action of the inductor.

[0035] Example 5

[0036] Since the wire posts on the core column are located at both ends and vertically, when the winding is completed and the wires at both ends are wound onto the wire posts, it is necessary to rotate the core column and adjust its position so that it is in the working position of the winding robot arm. This action needs to be independent of the core column's screw-in winding action to avoid the two actions affecting each other. Therefore, based on embodiment four, as follows... Figures 1 to 6As shown, the winding assembly also includes a mounting base 19, which is mounted on the rotating winding disc 2. A rotating shaft 20 is coaxially connected to the end of the precision screw 3 away from the screw-in sleeve 4. A shaft hole is provided on the mounting base 19, and the rotating shaft 20 is rotatably mounted within the shaft hole. A locking groove 21 is provided on the inner wall of the shaft hole, and a second electromagnet 22 is installed within the locking groove 21. A locking rod 23 is slidably disposed within the locking groove 21. Two locking holes 24 are evenly distributed along the circumference of the side wall of the rotating shaft 20. A return spring 25 is disposed within the locking groove 21, and both ends of the return spring 25 are respectively connected to the locking rod 23 and the mounting base 19. The locking rod 23 is close to the second electromagnet. A magnet 26 is installed at one end of magnet 22. When the second electromagnet 22 is energized, it generates magnetic poles with opposite magnetic properties to magnet 26. When the return spring 25 is in its normal state, one end of the locking rod 23 is fitted into one of the locking holes 24. When the screw-in sleeve 4 rotates and drives the core column to wind the wire, the second electromagnet 22 is de-energized, and the locking rod 23 is fitted into the locking hole 24, thereby locking the rotational freedom of the precision screw 3 and preventing the precision screw 3 from rotating with the screw-in sleeve 4. This allows the rubber drive wheel 32 to smoothly drive the screw-in sleeve 4 to rotate on the precision screw 3. After the winding is completed, the wire-cutting robot arm cuts the wire. Then the winding assembly rotates to the working position of the winding robot arm. The winding robot arm first winds one end of the wire onto the corresponding post. Then, the second electromagnet 22 is energized to attract the magnet 26, causing the locking rod 23 to compress the return spring 25 and move into the locking groove 21, separating the locking rod 23 from the locking hole 24. A drive motor is installed on the mounting base 19, and the output shaft of the drive motor is connected to the drive gear. A driven gear is mounted on the rotating shaft 20. The driven gear meshes with the drive gear, and the drive motor drives the rotating shaft 20 to rotate 180° through the meshing of the drive gear and the driven gear. To ensure accurate rotation of 180°, the rotating shaft 20 is rotated 180°. When the rotating shaft 20 is not rotated to the correct position, the second electromagnet 22 is de-energized, causing the locking rod 23 to extend out of the locking groove 21 under the reaction force of the return spring 25. The locking rod 23 then abuts against the side wall of the rotating shaft 20. When the next locking hole 24 corresponds to the locking rod 23, the locking rod 23 is inserted into the locking hole 24, thereby locking the position of the rotating shaft 20 and enabling the rotating shaft 20 to rotate precisely 180°. At this time, the precision screw 3 and the screw-in sleeve 4 will rotate together 180°, thereby causing the core column to rotate 180° and placing the other wire column in the working position of the winding robot arm. The winding robot arm completes the winding action of the other wire column, resulting in higher winding accuracy.

[0037] Example 6

[0038] Based on Example 5, such as Figures 1 to 7As shown, the loading arm assembly includes a loading base 34, a loading slide 35, a lifting frame 36, and a L-shaped loading rod 37. The loading slide 35 is slidably mounted on the loading base 34. The loading slide 35 moves closer to or further away from the center of the rotating winding disc 2. A loading cylinder 38 is vertically mounted on the top of the loading slide 35. The telescopic shaft of the loading cylinder 38 is connected to the lifting frame 36. One end of the L-shaped loading rod 37 is rotatably mounted on the lifting frame 36, and the other end is connected to a negative pressure suction cup 39. The rotation axis of the L-shaped loading rod 37 is horizontally set. A fixed-point loading mechanism is set within the working range of the L-shaped loading rod 37. The feeding mechanism includes a first linear drive module 40, a second linear drive module 41, and a feeding tray 42. The first linear drive module 40 is mounted on a fixed base 1. The second linear drive module 41 is mounted on a slide of the first linear drive module 40. A positioning post is fixed on the slide of the second linear drive module 41. A rectangular groove is formed at the bottom of the feeding tray 42, and the positioning post is adapted to the rectangular groove. Several inductive positioning grooves 43 are formed at the top of the feeding tray 42, and the inductive positioning grooves 43 are arranged in a rectangular array. The moving direction of the first linear drive module 40 is perpendicular to the moving direction of the second linear drive module 41, thus feeding the core post. Each core column is placed in the inductor positioning slot 43, keeping the core column loading state unchanged. Since the loading position of the negative pressure suction cup 39 remains constant, to ensure that each core column can move to the loading position of the negative pressure suction cup 39, a first linear drive module 40 and a second linear drive module 41 are set up. This gives the material tray 42 degrees of freedom of movement along the X and Y axes, allowing the core columns to move sequentially to the loading position of the negative pressure suction cup 39, achieving automatic core column loading. During loading, the lifting frame 36 drives the negative pressure suction cup 39 downwards, causing the negative pressure suction cup 39 to adsorb the core column under negative pressure. At this time, the axis of the core column is vertically set. Then, the lifting... The frame 36 returns to its original position, and the 7-shaped feeding rod 37 rotates the core column 180° so that the core column corresponds to the negative pressure tube 5. At this time, the axis of the core column is set horizontally. Then, the feeding slide 35 moves close to the negative pressure tube 5 so that the core column contacts the negative pressure tube 5. The negative pressure generated by the negative pressure tube 5 adsorbs the core column, and the negative pressure suction cup 39 disconnects the negative pressure, thereby automatically feeding the core column onto the negative pressure tube 5. Then, the feeding slide 35 drives the negative pressure suction cup 39 to return to its original position. The above actions are repeated to feed the next core column. In conjunction with the rotation of the rotating winding disc 2, the core columns are sequentially fed onto the negative pressure tube 5 of each winding assembly, realizing automated and precise feeding of the core columns.

[0039] Example 7

[0040] Based on Example 6, such as Figures 1 to 3As shown, a push cylinder 44 is installed on the feeding base 34. The telescopic shaft of the push cylinder 44 is connected to the feeding slide 35. By pushing the cylinder 44, the feeding slide 35 is moved closer to or away from the winding assembly, thereby transferring the core column on the negative pressure suction cup 39 to the negative pressure tube 5 to complete the feeding. A feeding shaft 45 is rotatably installed on the lifting frame 36. One end of the 7-shaped feeding rod 37 is fixedly fitted on the feeding shaft 45. A feeding motor 46 is installed on the lifting frame 36. The output shaft of the feeding motor 46 is connected to the feeding shaft 45. The feeding motor 46 drives the feeding shaft 45 to rotate 180°, which in turn drives the 7-shaped feeding rod 37 to rotate 180°, changing the state of the core column and feeding it onto the negative pressure tube 5, facilitating the winding action of the core column.

[0041] Example 8

[0042] Based on Example 7, such as Figures 1 to 3 As shown, a winding spindle 47 is coaxially fixed at the bottom of the rotating winding disc 2. The winding spindle 47 is rotatably connected to the fixed base 1 through a bearing. A main motor is installed inside the fixed base 1. The output shaft of the main motor is driven to the winding spindle 47 through a coupling. The main motor drives the rotating winding disc 2 to rotate, causing several winding components to clamp the core column in sequence for winding. A pneumatic slip ring 48 is fitted on the winding spindle 47. The precision screw 3 is hollow. A negative pressure air pipe 49 is connected to the pneumatic slip ring 48. The negative pressure air pipe 49 passes through the precision screw 3 and connects to the negative pressure pipe 5. The pneumatic slip ring 48 facilitates the arrangement of the negative pressure air pipe 49 and the wires of the drive motor, thus solving the problem of unwinding. The negative pressure air pipe 49 is connected to a negative pressure pump, and the clamping of the core column is completed by negative pressure. This is existing technology and will not be described in detail.
