Description

Technical Field

[0001] The present invention relates to the technical field of toroidal inductor winding, and specifically to a circumferential winding device for toroidal inductors. Background Art

[0002] A toroidal coil inductor (inductor coil) is an electromagnetic induction component wound with insulated wires and is also one of the commonly used components in electronic circuits. It is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance and only impedes the change of current. When manufacturing a toroidal inductor, winding is required. Since the magnetic core of a toroidal inductor is toroidal, when threading the wire through the magnetic core, it needs to pass through the inner through-hole of the toroidal magnetic core and then wind around the outside of the magnetic core to complete the circumferential winding. This operation requires continuously winding the wire around the toroidal magnetic core, which requires pulling the wire along an arc path or a circular path. However, existing winding machines are difficult to complete the above complex operations, resulting in the winding of toroidal magnetic cores being completed manually, with poor winding consistency and difficult to improve efficiency. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a circumferential winding device for toroidal inductors, which can automatically complete the winding operation of toroidal magnetic cores and has the advantages of high consistency, uniform winding, and high efficiency.

[0011] Further, two upper driving gears are symmetrically arranged along the length direction of the upper moving seat in the upper installation groove. The upper driving gears are rotationally connected to the upper moving seat through a first shaft. Two lower driving gears are symmetrically arranged along the length direction of the lower moving seat in the lower installation groove. The lower driving gears are rotationally connected to the lower moving seat through a second shaft. An external gear ring is sleeved on the winding ring. Both the upper driving gears and the lower driving gears are engaged with the external gear ring. A driving motor is installed on the side wall of the upper moving seat. The output shaft of the driving motor is in transmission connection with one of the first shafts.

[0012] Further, annular guiding grooves are formed on both sides of the winding ring. The annular guiding grooves are concentric with the winding ring.

Detailed implementation mode

[0024] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0025] Embodiment 1

[0026] As Figures 1 to 6As shown, a surrounding winding device for a toroidal inductor comprises a winding workbench 1, a rotating tooling mechanism and a toroidal winding mechanism are arranged on the winding workbench 1, a positioning circular hole 2 is opened on the winding workbench 1, the rotating tooling mechanism comprises a horizontal slide plate 3, a rotating shaft 4 and a rubber roller 5, a plurality of horizontal slide plates 3 are evenly arranged around the positioning circular hole 2 on the winding workbench 1, the horizontal slide plates 3 have the freedom to move radially along the positioning circular hole 2, the rotating shaft 4 is rotatably mounted on the horizontal slide plate 3, the axis of the rotating shaft 4 is vertically arranged, the rubber roller 5 is fixedly sleeved on the rotating shaft 4, the plurality of rubber rollers 5 are used to coaxially fix the toroidal inductor with the positioning circular hole 2, the toroidal winding mechanism comprises an upper semicircular ring 6, a lower semicircular ring 7 and a wire reel 8, the upper semicircular ring 6 is provided with a plurality of The circular ring 6 and the lower semicircular ring 7 both have the freedom to move axially along the positioning circular hole 2. The upper semicircular ring 6 contacts the lower semicircular ring 7 to form a winding ring. The axis of the winding ring is perpendicular to the axis of the positioning circular hole 2. The wire reel 8 is installed on the inner ring of the winding ring. The end of the upper semicircular ring 6 that contacts the lower semicircular ring 7 is located between multiple rubber rollers 5. The annular magnetic core is first mounted on the rotating fixture mechanism, and multiple horizontal slides 3 move synchronously. When the annular magnetic core is loaded, the horizontal slide 3 moves away from the positioning circular hole 2, so that the space formed by the multiple rubber rollers 5 is larger than the diameter of the annular magnetic core. At the same time, the upper semicircular ring 6 moves upward and the lower semicircular ring 7 moves downward, so that a loading space is formed between the upper semicircular ring 6 and the lower semicircular ring 7. The feeding space is then moved by a mechanical arm or manually. The annular magnetic core is placed between multiple rubber rollers 5 from the loading space, and then the horizontal slide 3 moves close to the positioning circular hole 2 to make the rubber roller 5 contact the annular magnetic core. The annular magnetic core is clamped by multiple rubber rollers 5 so that the axis of the annular magnetic core is set vertically. Then the upper semicircular ring 6 moves downward and the lower semicircular ring 7 moves upward so that the upper semicircular ring 6 contacts the lower semicircular ring 7 to form a winding ring. At this time, the winding ring passes through the annular magnetic core. Then, the wire on the wire reel 8 is manually wound around the annular magnetic core, and then the winding operation is performed. During winding, the rotating shaft 4 drives the rubber roller 5 to rotate, and the rubber roller 5 drives the annular magnetic core to rotate around its own axis. The winding ring drives the wire reel 8 thereon to rotate. Since the winding ring passes through the annular magnetic core, The wire reel 8 cyclically rotates from the outside of the annular core to the inside of the annular core, thereby winding the wire on the annular core, and the rotation of the annular core makes the winding path annular, completing the automatic winding of the annular core, which has the advantages of high consistency, uniform winding, and high efficiency. After the winding is completed, the upper semicircular ring 6 moves upward and the lower semicircular ring 7 moves downward to form a loading space, so that the wound annular core can be unloaded from the loading space. When unloading, the horizontal slide 3 moves away from the positioning circular hole 2, so that the rubber roller 5 is separated from the annular core, so that the annular core can be unloaded smoothly, and the next annular core can be loaded between multiple rubber rollers 5. By controlling the rotation speed of the annular core and the rotation speed of the winding ring, the winding spacing can be adjusted. Preferably, the rotary tooling mechanism adopts three groups, and the tooling of the annular core is completed by three-point contact.

[0027] Further, a locking screw rod 49 is movably inserted through the wire reel 8. A locking threaded hole is formed in the inner wall of the winding ring. The tail of the locking screw rod 49 is threadedly fitted in the locking threaded hole, and the head of the locking screw rod 49 abuts against the wire reel 8. The wire reel 8 is detachably mounted on the winding ring through the locking screw rod 49. When the wire on the wire reel 8 is used up, a new wire reel 8 can be replaced to continue the winding operation, which is convenient for replacing the wire reel 8.

[0028] Embodiment 2

[0029] On the basis of Embodiment 1, as Figures 1 to 3As shown in the figure, the winding workbench 1 is provided with a horizontal chute 9 at the position where the horizontal slide plate 3 is arranged. The horizontal chute 9 communicates with the positioning circular hole 2. The horizontal slide plate 3 is slidably adapted to the horizontal chute 9. One end of the horizontal slide plate 3 away from the positioning circular hole 2 is connected with a spring 10. One end of the spring 10 away from the horizontal slide plate 3 is connected with the winding workbench 1. When the spring 10 is in a normal state, the diameter of the annular space formed by a plurality of rubber rollers 5 is smaller than the diameter of the annular inductor. A driving disk 11 is coaxially arranged in the positioning circular hole 2. The driving disk 11 is rotationally connected with the winding workbench 1 through a main shaft 12. One end of the horizontal slide plate 3 close to the driving disk 11 is fixed with a wedge block 13. One side of the wedge block 13 is provided with a wedge surface 14. A plurality of extrusion and pushing rods 15 are fixed on the side wall of the driving disk 11. The plurality of extrusion and pushing rods 15 correspond to the plurality of wedge blocks 13 one by one. The wedge surface 14 is located on the moving path of the extrusion and pushing rod 15. One end of the main shaft 12 passes through the bottom of the winding workbench 1 and is connected with a gear 16. A cylinder 17 is horizontally installed at the bottom of the winding workbench 1. The telescopic shaft of the cylinder 17 is connected with a rack 18. The rack 18 meshes with the gear 16. When the annular magnetic core is processed, the cylinder 17 extends to drive the rack 18 to move. The rotation of the main shaft 12 is driven by the meshing of the rack 18 and the gear 16. The main shaft 12 drives the driving disk 11 to rotate. The driving disk 11 drives the plurality of extrusion and pushing rods 15 thereon to rotate. The plurality of extrusion and pushing rods 15 correspond to the plurality of horizontal slide plates 3 one by one. The driving disk 11 drives the extrusion and pushing rod 15 to move close to the wedge surface 14 of the wedge block 13, so that the extrusion and pushing rod 15 extrudes the wedge surface 14. Under the action of the wedge surface 14, the horizontal slide plate 3 extrudes the spring 10 and moves away from the positioning circular hole 2, so that the space between the plurality of rubber rollers 5 is larger than the size of the annular magnetic core, and the annular magnetic core can be smoothly loaded between the plurality of rubber rollers 5. After the annular magnetic core is loaded between the plurality of rubber rollers 5, the cylinder 17 contracts and resets. The reverse rotation of the main shaft 12 is driven by the meshing of the rack 18 and the gear 16. The main shaft 12 drives the driving disk 11 to reverse and reset, so that the extrusion and pushing rod 15 deflects away from the wedge block 13. At this time, the horizontal slide plate 3 moves close to the positioning circular hole 2 and resets under the reaction force of the spring 10, so that the rubber roller 5 contacts the annular magnetic core for clamping and processing. Since the diameter of the annular space formed by the plurality of rubber rollers 5 is smaller than the diameter of the annular magnetic core when the spring 10 is in a normal state, the rubber roller 5 abuts against the annular magnetic core under the action of the spring 10 to complete the processing, and has good processing stability.

[0030] Further, one end of the rotating shaft 4 passes through the bottom of the horizontal slide plate 3 and is connected with a pulley 19. The pulleys 19 on multiple horizontal slide plates 3 are connected by a belt 20 in a transmission manner. A motor 21 is arranged at the bottom of one of the horizontal slide plates 3. The output shaft of the motor 21 is connected with the corresponding rotating shaft 4 through a coupling. By driving one of the rotating shafts 4 to rotate through the motor 21, the pulley 19 on this rotating shaft 4 is driven to rotate. This pulley 19 drives the other pulleys 19 to rotate through the belt 20, so that multiple rubber rollers 5 rotate synchronously. The rubber rollers 5 drive the toroidal magnetic core to rotate, indirectly forming a loop for the winding path, so that winding can be carried out along the path of the toroidal magnetic core, realizing automatic winding of the toroidal magnetic core.

[0031] Embodiment III

[0032] Since the horizontal slide plate 3 has a linear movement degree of freedom for loading and unloading the toroidal magnetic core, the distance between multiple pulleys 19 will change. Directly driving through the belt 20 will limit the movement degree of freedom of the horizontal slide plate 3. Therefore, on the basis of Embodiment II, as Figures 1 to 3 shown, a tensioning mechanism is arranged at the bottom of the winding workbench 1. The tensioning mechanism includes a tensioning slide seat 22 and a tensioning spring 23. A tensioning chute 24 is opened at the bottom of the winding workbench 1. The tensioning slide seat 22 is slidably fitted in the tensioning chute 24. The two ends of the tensioning spring 23 are respectively connected with the tensioning slide seat 22 and the winding workbench 1. A tensioning pulley 25 is rotatably arranged on the tensioning slide seat 22. The belt 20 bypasses the tensioning pulley 25. When the horizontal slide plate 3 moves, the tensioning slide seat 22 will move accordingly, enabling the belt 20 to adapt to the change in the distance between multiple pulleys 19. Specifically, when the horizontal slide plate 3 moves away from the positioning circular hole 2, under the action of the belt 20, the tensioning slide seat 22 will stretch the tensioning spring 23 and move close to the positioning circular hole 2. When the horizontal slide plate 3 moves close to the positioning circular hole 2 and resets, the tensioning slide seat 22 moves away from the positioning circular hole 2 under the action of the tensioning spring 23, so that the belt 20 can smoothly adapt to the position change of the pulley 19 and always keep the belt 20 in a tensioned state, enabling multiple rotating shafts 4 to smoothly drive the rubber rollers 5 to rotate.

[0033] Embodiment IV

[0034] On the basis of Embodiment III, as Figures 1 to 4As shown, the annular winding mechanism further includes an upper moving seat 26, a lower moving seat 27 and a C-shaped fixed seat 28. The C-shaped opening of the C-shaped fixed seat 28 faces the rotary tooling mechanism. A bidirectional threaded lead screw 29 is rotatably arranged in the C-shaped opening of the C-shaped fixed seat 28. Screw sliders 30 are threadedly sleeved on two threaded segments of the bidirectional threaded lead screw 29 with opposite thread directions. The screw sliders 30 are slidably adapted to the C-shaped fixed seat 28. The upper moving seat 26 and the lower moving seat 27 are respectively connected to the two screw sliders 30. A lead screw motor 31 is installed at the top of the C-shaped fixed seat 28. The output shaft of the lead screw motor 31 is drivingly connected to the bidirectional threaded lead screw 29. An upper installation groove 32 is formed at the bottom of the upper moving seat 26. The upper semi-ring 6 is slidably adapted to the upper installation groove 32. A lower installation groove 33 is formed at the top of the lower moving seat 27. The lower semi-ring 7 is slidably adapted to the lower installation groove 33. By driving the bidirectional threaded lead screw 29 to rotate through the lead screw motor 31, since the thread directions of the two screw sliders 30 are opposite, the moving directions of the two screw sliders 30 are opposite, so that the moving directions of the upper moving seat 26 and the lower moving seat 27 are opposite. When feeding the annular magnetic core, the upper moving seat 26 moves upward and the lower moving seat 27 moves downward, so that the upper semi-ring 6 and the lower semi-ring 7 are separated to form a feeding space. When the feeding is completed and winding is to be carried out, the upper moving seat 26 moves downward and the lower moving seat 27 moves upward, so that the upper semi-ring 6 and the lower semi-ring 7 are in contact to form a winding ring for winding operation.

[0035] Embodiment Five

[0036] On the basis of Embodiment Four, as Figures 1 to 5As shown in the figure, two upper driving gears 34 are symmetrically arranged along the length direction of the upper moving seat 26 in the upper installation groove 32. The upper driving gears 34 are rotationally connected to the upper moving seat 26 through the first shaft 35. Two lower driving gears 36 are symmetrically arranged along the length direction of the lower moving seat 27 in the lower installation groove 33. The lower driving gears 36 are rotationally connected to the lower moving seat 27 through the second shaft 37. An external gear ring 38 is sleeved on the wire winding ring. Both the upper driving gears 34 and the lower driving gears 36 are engaged with the external gear ring 38. A driving motor 39 is installed on the side wall of the upper moving seat 26. The output shaft of the driving motor 39 is drivingly connected to one of the first shafts 35. The driving motor 39 drives the first shaft 35 connected thereto to rotate. The first shaft 35 drives the upper driving gear 34 thereon to rotate. The upper driving gear 34 drives the wire winding ring to rotate through the engagement with the external gear ring 38. The wire winding ring drives the remaining upper driving gears 34 and lower driving gears 36 to rotate, so that the wire winding ring can smoothly drive the wire spool 8 to rotate for wire winding operation. The positions of the wire winding ring are limited by the two upper driving gears 34 and the two lower driving gears 36, so that the wire winding ring rotates within the space formed by the upper driving gears 34 and the lower driving gears 36 to realize automatic wire winding operation; it should be noted that the external gear ring 38 also adopts a split structure, with half installed on the upper half ring 6 and the other half installed on the lower half ring 7. When the upper half ring 6 contacts the lower half ring 7, a complete external gear ring 38 is formed.

[0037] Embodiment Six

[0038] Since the upper driving gears 34 are arranged above the upper half ring 6 and the lower driving gears 36 are arranged below the lower half ring 7, when the upper half ring 6 and the lower half ring 7 are separated, the upper half ring 6 will fall off the upper moving seat 26. Therefore, on the basis of Embodiment Five, as Figures 1 to 5As shown in the figure, annular guide grooves 40 are provided on both sides of the winding ring. The annular guide grooves 40 are concentric with the winding ring. Guide components are provided on both sides of the upper moving seat 26 and both sides of the lower moving seat 27. The guide component includes a screw rod 41 and a bearing 42. The screw rod 41 is threadedly installed. The tail of the screw rod 41 is connected to the inner ring of the bearing 42, and the outer ring of the bearing 42 is fitted in the annular guide groove 40. Through the setting of the guide component, it is convenient to install the upper semi-ring 6 and the lower semi-ring 7, and can limit the installation positions of the upper semi-ring 6 and the lower semi-ring 7, avoiding the upper semi-ring 6 from detaching from the upper moving seat 26 and the lower semi-ring 7 from detaching from the lower moving seat 27. The specific installation process is as follows: Place the lower semi-ring 7 into the lower installation groove 33, so that the external gear ring 38 on the lower semi-ring 7 meshes with the lower driving gear 36. Insert the end of the screw rod 41 provided with the bearing 42 into the lower installation groove 33 through the side wall opening of the lower moving seat 27. The side wall opening of the lower moving seat 27 is a threaded hole. The screw rod 41 is a stepped shaft. The small diameter end is connected to the inner ring of the bearing 42, and the large diameter end is threadedly fitted to the side wall opening. After screwing the screw rod 41 tightly on the lower moving seat 27, the bearing 42 is fitted in the annular guide groove 40. Through the cooperation of the bearing 42 and the annular guide groove 40, the lower semi-ring 7 is slidably connected to the lower moving seat 27. At the same time, the bearing 42 does not affect the rotational freedom of the winding ring. Similarly, the upper semi-ring 6 is installed on the upper moving seat 26 in the same way. Through the cooperation of the bearing 42 and the annular wire groove 40 in the guide component, the upper semi-ring 6 is slidably connected to the upper moving seat 26, ensuring that after the upper semi-ring 6 and the lower semi-ring 7 are separated, the upper semi-ring 6 and the lower semi-ring 7 will not fall off.

[0039] Embodiment Seven:

[0040] Since the upper semi-ring 6 and the lower semi-ring 7 can be switched with each other, that is, the upper semi-ring 6 rotates between the upper moving seat 26 and the lower moving seat 27, and the lower semi-ring 6 rotates between the upper moving seat 26 and the lower moving seat 27, there will be a situation where the upper semi-ring 6 is simultaneously located in the upper moving seat 26 and the lower moving seat 27, resulting in the upper semi-ring 6 being unable to separate from the lower semi-ring 7 to form a feeding space. Therefore, on the basis of Embodiment Six, as Figures 1 to 6As shown, an upper positioning component is provided on the upper moving seat 26. The upper positioning component includes an electromagnet 43, a positioning pin 44, a permanent magnet 45, and a positioning spring 46. A positioning installation groove 47 is formed in the side wall of the upper installation groove 32 on the upper moving seat 26. The electromagnet 43 is installed in the positioning installation groove 47. One end of the positioning pin 44 is slidably fitted in the positioning installation groove 47. One end of the positioning pin 44 close to the permanent magnet 45 is connected to the permanent magnet 45. The two ends of the positioning spring 46 are respectively connected to the upper moving seat 26 and the positioning pin 44. A positioning jack 48 is formed on the end face of the upper half ring 6. When the electromagnet 43 is energized, it generates a magnetic pole with a different magnetism from that of the permanent magnet 45. When the positioning spring 46 is in a normal state, the positioning pin 44 is inserted into the positioning jack 48. At this time, the upper half ring 6 and the lower half ring 7 are arranged symmetrically up and down along the horizontal plane. A lower positioning component is provided on the lower moving seat 27. The structure of the lower positioning component is the same as that of the upper positioning component. The lower positioning component is used to position the lower half ring 7. When the winding ring is winding, the electromagnet 43 is in an energized state. The electromagnet 43 attracts the permanent magnet 45, causing the positioning pin 44 to compress the positioning spring 46 and disengage from the positioning jack 48, so that the winding ring can rotate normally for winding operations. When loading and unloading the toroidal core, the driving motor 39 stops and the electromagnet 43 is de-energized. The positioning pin 44 moves close to the winding ring under the reaction force of the positioning spring 46, causing the positioning pin 44 to abut against the end face of the winding ring. After the driving motor 39 stops, the winding ring will continue to rotate due to inertia. When the positioning jack 48 on the upper half ring 6 corresponds to the positioning pin 44 of the upper positioning component, the positioning pin 44 is inserted into the positioning jack 48 under the action of the positioning spring 46. At the same time, the positioning jack 48 on the lower half ring 7 corresponds to the positioning pin 44 of the lower positioning component, causing the positioning pin 44 in the lower positioning component to be inserted into the positioning jack 48 of the lower half ring 7, thereby completing the positioning of the upper half ring 6 and the lower half ring 7. When the winding ring stops rotating, the upper half ring 6 only cooperates with the upper moving seat 26, and the lower half ring 7 only cooperates with the lower moving seat 27. Then the lead screw motor 31 is started, causing the upper moving seat 26 to move upward and the lower moving seat 27 to move downward, so that the upper half ring 6 and the lower half ring 7 can be smoothly separated to form a loading space, thereby enabling the toroidal core to be loaded and unloaded through the loading space.
