Description

Technical Field

[0001] The present application relates to the technical field of winding devices, and in particular to an automatic winding device for a mutual inductor. Background Art

[0002] In the production process of the mutual inductor, the winding station is to wind the enameled wire on the insulating ring frame. The existing winding equipment for the insulating ring frame generally includes a winding device and a clamping device. The clamping device generally includes a plurality of vertical shafts slidably arranged on a workbench. The top of the vertical shaft is provided with a clamping wheel. The insulating ring frame between the clamping wheels is clamped by moving the vertical shafts close to each other. When the winding device winds the insulating ring frame, the insulating ring frame also needs to rotate in coordination, so that the turns of the enameled wire can be evenly arranged and tightly wound on the insulating ring frame, and the rotation of the insulating ring frame is achieved by rotating the vertical shaft and the clamping wheel.

[0003] The existing insulating ring skeletons have different specifications and diameters, so the rotation speed of the insulating ring skeletons should also be adjusted accordingly. For example, the insulating ring skeleton with a larger diameter should not rotate slower than the insulating ring skeleton with a smaller diameter so that the turns of the enameled wire can be evenly arranged and tightly wound on the insulating ring skeleton. Otherwise, there will be gaps between the turns of the enameled wire and the arrangement will be loose. To solve this problem, the existing winding device adjusts the rotation speed of the vertical shaft on-site according to the specifications of the insulating ring skeleton to be produced, which is more troublesome. It needs to be adjusted every time the insulating ring skeleton is replaced, which affects the production efficiency.

[0004] Through searching, Chinese patent announcement number CN117198739A discloses a wire winding device for transformer production, including a base and a transformer annular core, a winding component is fixed on the upper end of the base, a cylinder is fixed on the front side of the upper end of the base, a No. 1 motor is fixed on the upper end of the base, a clamping component 1 is fixed on the output end of the cylinder, a clamping component 2 is fixed on the rear end of the clamping component 1, an adjustment component is fixed on the front end of the winding component, a positioning plate is fixed on the outer surface of the cylinder output end, and the positioning plate is fixedly connected to the front end of the winding component. The wire winding device for transformer production described in the present invention can clamp the annular cores of different diameters of the transformer through the provided clamping component 1, and then wind the wire around it through the winding component.

[0005] The above scheme clamps the insulating annular skeleton by the support rod, and drives the transmission rod to rotate by the micro motor, so that the transmission rod drives the support rod to rotate, and then drives the insulating annular skeleton to rotate. When replacing the insulating annular skeletons with different diameters, the above scheme needs to adjust the speed by the micro motor every time. The debugging process is cumbersome, and it is necessary to determine whether to make another adjustment based on the effect of the debugging. Summary of the invention

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-9 This application is described in further detail.

[0033] The embodiment of the present application discloses an automatic winding device for a mutual inductor, comprising a workbench 1, and a mounting plate 2 fixedly arranged on the upper end surface of the workbench 1, a plurality of sliders 3 are slidably arranged on the upper end surface of the workbench 1, the upper end surface of each slider 3 is rotatably connected to a vertical shaft 4, a clamping wheel 5 is fixedly arranged on the top of each vertical shaft 4, the slider 3 is slidably arranged on the upper end surface of the workbench 1 along the line connecting the geometric centers formed by the plurality of vertical shafts 4, a winding device is arranged on the mounting plate 2, when in use, an insulating annular skeleton 6 is placed between the plurality of clamping wheels 5, so that the plurality of vertical shafts 4 are moved toward the geometric centers formed by the plurality of vertical shafts 4 through the sliders 3, so that the clamping wheels 5 The wheel 5 clamps the insulating annular skeleton 6, so that the vertical shaft 4 rotates and drives the insulating annular skeleton 6 to rotate through the clamping wheel 5. At the same time, the winding device winds the enameled wire around the insulating annular skeleton 6. Due to the slow rotation of the insulating annular skeleton 6, the enameled wire is evenly wound around the insulating annular skeleton 6 to achieve the purpose of winding. A transmission device is arranged on the vertical shaft 4 on the right side close to the mounting plate 2, and a driving device is arranged at a position corresponding to the transmission device on the mounting plate 2. A speed regulating device is arranged between the driving device and the transmission device. The driving device drives the vertical shaft 4 to rotate through the speed regulating device and the transmission device, and then drives the insulating annular skeleton 6 to rotate through the clamping wheel 5.

[0034] A power device is arranged below the mounting plate 2 , and the output end of the power device is connected to each vertical shaft 4 . The power device is used to drive the vertical shaft 4 to synchronously move toward or away from the geometric center formed by the plurality of vertical shafts 4 .

[0035] During use, since the insulating annular skeleton 6 has different specifications and diameters, when the winding device winds the insulating annular skeleton 6, the rotation speed of the insulating annular skeleton 6 needs to be adaptively adjusted to keep the enameled wire wound on the insulating annular skeleton 6 even and tight. When the diameter of the insulating annular skeleton 6 to be wound is larger than the originally wound insulating annular skeleton 6, the rotation speed of the insulating annular skeleton 6 becomes slower accordingly to ensure that the enameled wire wound on the insulating annular skeleton 6 is equally even and tight. When the diameter of the insulating annular skeleton 6 to be wound is smaller than the originally wound insulating annular skeleton 6, the rotation speed of the insulating annular skeleton 6 becomes faster accordingly to ensure that the enameled wire wound on the insulating annular skeleton 6 is equally even and tight.

[0036] Due to the different specifications and diameters of the insulating annular skeleton 6, the vertical shaft 4 and the clamping wheel 5 move different distances to the geometric center formed by the plurality of vertical shafts 4 when clamping the insulating annular skeleton 6. The speed regulating device adjusts the rotation speed of the vertical shaft 4 based on the distance of movement of the inductive vertical shaft 4. The greater the distance that the vertical shaft 4 moves to the geometric center formed by the plurality of vertical shafts 4, the faster the speed regulating device adjusts the rotation speed of the vertical shaft 4. The rotation speed of the insulating annular skeleton 6 can be automatically adjusted according to the diameter of the insulating annular skeleton 6, so that the number of turns of the enameled wire wound on the insulating annular skeleton 6 by the winding coil 15 is closely arranged.

[0037] In this embodiment, the vertical shaft 4 near the right side of the mounting plate 2 is the active vertical shaft 7, and the transmission device includes a moving block 8 slidably arranged on the upper end surface of the mounting plate 2 along the moving direction of the active vertical shaft 7, and a first bevel gear 9 fixedly arranged on the active vertical shaft 7. The internal rotation of the moving block 8 is connected with a transmission shaft 10, and a second bevel gear 11 is fixedly arranged at one end of the transmission shaft 10 near the active vertical shaft 7. The second bevel gear 11 is meshed with the first bevel gear 9, and a conical block 12 is fixedly arranged at the other end of the transmission shaft 10. The moving block 8 is fixedly arranged through a connecting block 13 and a slider 3 rotatably connected to the bottom end of the active vertical shaft 7; the conical block 12 rotates through the transmission shaft 10, the second bevel gear 11 and the first bevel gear 9 in sequence. 1 and the first bevel gear 9 drive the active vertical shaft 7 to rotate, and then drive the insulating annular skeleton 6 to rotate through the corresponding clamping wheel 5; when the active vertical shaft 7 slides on the upper end surface of the workbench 1 under the drive of the power device, the active vertical shaft 7 drives the moving block 8 to move synchronously through the corresponding slider 3 and the connecting block 13, and the moving block 8 moves to drive the transmission shaft 10, the conical block 12 and the second bevel gear 11 to move synchronously, so that the second bevel gear 11 keeps meshing with the first bevel gear 9, and the speed regulating device adjusts the rotation speed of the vertical shaft 4 based on the moving distance of the inductive conical block 12. The greater the distance that the vertical shaft 4 moves toward the geometric center formed by the plurality of vertical shafts 4, the faster the speed regulating device adjusts the rotation speed of the vertical shaft 4.

[0038] In this embodiment, the speed regulating device includes a rotatable speed regulating body 14, which is a geometric body with a large end close to the geometric center formed by a plurality of vertical shafts 4 and a small end away from the geometric center formed by a plurality of vertical shafts 4, and a conical surface on the outer surface. The outer surface of the speed regulating body 14 fits the conical surface of the conical block 12, and the edge line of the longitudinal section of the speed regulating body 14 close to the conical block 12 is parallel to the moving direction of the moving block 8; the driving device drives the speed regulating body 14 to rotate and drives the conical block 12 to rotate, and the conical block 12 then drives the clamping wheel 5 to rotate through the transmission shaft 10, the second conical gear 11, the first conical gear 9 and the active vertical shaft 7 in turn, thereby achieving the purpose of driving the insulating annular skeleton 6 to rotate; when the active vertical shaft 7 moves, the active vertical shaft 7 passes through the The corresponding slider 3, connecting block 13 and moving block 8 drive the transmission shaft 10 to move, and the movement of the transmission shaft 10 drives the conical block 12 to move. Since the longitudinal section of the speed regulating body 14 is close to the edge line of the conical block 12 and is parallel to the moving direction of the moving block 8, the conical surface of the conical block 12 always fits with the conical surface of the speed regulating body 14 to maintain static friction transmission. The greater the distance that the active vertical shaft 7 moves toward the geometric center composed of several vertical shafts 4, the smaller the diameter of the insulating annular skeleton 6 is, and the larger the diameter of the position where the speed regulating body 14 contacts the conical block 12. Under the same rotation speed of the speed regulating body 14, the faster the rotation speed of the conical block 12 is, and the faster the rotation speed of the insulating annular skeleton 6 is, and the winding device maintains the same tightness on the number of turns of the enameled wire when winding the insulating annular skeleton 6.

At the same time, the driving device drives the active vertical shaft 7 to rotate through the speed regulating body 14, and drives the insulating annular skeleton 6 to rotate through the clamping wheel 5, so that the number of turns of the enameled wire wound on the sliding insulating annular skeleton 6 is tight and uniform.

[0041] In order to avoid the moving route of the vertical shaft 4, in this embodiment, the auxiliary gear 19 is fixedly arranged on the upper end surface of the workbench 1 through a fixing plate 24, and the auxiliary gear 19 is rotatably connected to the fixing plate 24, and the fixing plate 24 does not interfere with the moving route of the corresponding vertical shaft 4.

[0042] In order to achieve the purpose of the first motor 23 driving the speed regulating body 14 to rotate at the same time, in this embodiment, the driving device includes the first motor 23, and a planetary gear reducer 25 arranged between the first motor 23 and the speed regulating body 14, the output shaft of the first motor 23 is connected to the input end of the planetary gear reducer 25, and the output end of the planetary gear reducer 25 is connected to the speed regulating body 14; the first motor 23 rotates to drive the winding coil 15 to rotate while driving the input end of the planetary gear reducer 25 to rotate, and then the output end of the planetary gear drives the speed regulating body 14 to rotate, so that the speed regulating body 14 drives the conical block 12 to rotate, and then the conical block 12 drives the active vertical shaft 7 to rotate, and then the clamping wheel 5 drives the insulating annular skeleton 6 to rotate. The function of the planetary gear reducer 25 is to reduce the rotation speed of the first motor 23 to the speed range required by the insulating annular skeleton 6.
