[0022] The following, in conjunction with the accompanying drawings, clearly and completely describes the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and their technical features can be combined with each other.

[0023] During the coil forming process, multiple steps are required to obtain the desired coil. The first step is coil winding, which is usually performed using a winding fork device. However, existing winding fork devices use a power mechanism to drive a single winding fork assembly to rotate to perform the coil winding operation. This can only achieve the winding operation of a single coil at a time, resulting in low coil winding efficiency, which affects the overall production efficiency of the product.

[0024] Based on this, it is necessary to provide a new solution for a winding flyer fork device to improve the technical problem that the coil winding efficiency of the existing winding flyer fork device is low and affects the overall production efficiency of the product.

[0025] like Figure 1 and Figure 2As shown, in one embodiment, the present application provides a winding flyer device 1, which includes a frame 100, a power mechanism 200, and a plurality of winding flyer assemblies 300, each mounted on the frame 100. Specifically, the frame 100 may include a horizontally extending flyer mounting base 110, wherein the flyer mounting base 110 has a plurality of flyer mounting holes 120 sequentially formed along its extension direction, for rotatably mounting the plurality of winding flyer assemblies 300 in a one-to-one correspondence. The flyer mounting holes 120 may specifically include a first assembly hole section 121, a transition hole section 122, and a second assembly hole section 123. The first assembly hole section 121, the transition hole section 122, and the second assembly hole section 123 are sequentially connected in a vertical direction, and the first assembly hole section 121 is equipped with a first bearing 11, and the second assembly hole section 123 is equipped with a second bearing 12, so that the corresponding winding flyer assembly 300 can be rotatably assembled through the cooperation between the first bearing 11 and the second bearing 12. The power mechanism 200 drives and connects multiple winding flyer fork assemblies 300 respectively, so as to drive the multiple winding flyer fork assemblies 300 to rotate in the corresponding flyer fork mounting holes 120 respectively.

[0026] It should be noted that the present winding flyer device 1 can also be used in applications where multiple shafts need to be integrated into a winding machine for winding a core inductor. Depending on the actual winding requirements, the specific number of flyer mounting holes 120 on the flyer mounting base 110 and the specific number of winding flyer assemblies 300 can be adjusted accordingly, simply ensuring a one-to-one correspondence between the two.

[0027] In the present application, each fork mounting hole 120 on the fork mounting seat 110 includes a first assembly hole section 121, a transition hole section 122 and a second assembly hole section 123 which are connected in sequence along the vertical direction. When the corresponding winding fork assembly 300 is assembled, the first bearing 11 can be directly assembled in the first assembly hole section 121 and the second bearing 12 can be assembled in the second assembly hole section 123 without providing a separate bearing sleeve on each fork mounting hole 120. The first bearing 11 and the second bearing 12 can be assembled between each fork mounting hole 120 and the corresponding winding fork assembly 300 to ensure that each winding fork assembly 300 can rotate in the corresponding fork mounting hole 120. At the same time, its flyer mounting seat 110 can form a multi-point support from top to bottom for the corresponding winding flyer assembly 300 through each flyer mounting hole 120, ensuring that its flyer mounting seat 110 can firmly support multiple winding flyer assemblies 300 without causing compression deformation to cause the winding flyer assembly 300 to tilt and affect the coil winding quality. In this way, the present winding flyer device 1 can achieve a high degree of integration of multiple winding flyer assemblies 300, so that its multiple winding flyer assemblies 300 can be driven by its power mechanism 200 and rotate in the corresponding flyer mounting hole 120 respectively, so as to efficiently realize the simultaneous winding operation of multiple coils and improve the overall production efficiency of the product.

[0028] In some examples, such as Figure 1 and Figure 2 As shown, the aperture of the first assembly hole section 121 is larger than the aperture of the transition hole section 122, and the aperture of the transition hole section 122 is larger than the aperture of the second assembly hole section 123. Accordingly, the diameter of the first bearing 11 is larger than the diameter of the second bearing 12. In this way, when machining each flyer mounting hole 120 on the flyer mounting base 110, only one clamping is required to sequentially mill the first assembly hole section 121, the transition hole section 122, and the second assembly hole section 123 of each flyer mounting hole 120 from top to bottom on the flyer mounting base 110. This reduces machining difficulty while ensuring concentricity among the first assembly hole section 121, the transition hole section 122, and the second assembly hole section 123, thereby reducing the subsequent rotation and swing of each winding flyer assembly 300 within the corresponding flyer mounting hole 120 and preventing air leakage.

[0029] In some examples, such as Figures 1 to 4As shown, the winding flyer fork assembly 300 may specifically include a rotating ventilation shaft 310, a flyer fork shaft 320 and a pneumatic wire clamping mechanism 330. The rotating ventilation shaft 310 is assembled in the corresponding flyer fork mounting hole 120 through the cooperation of the first bearing 11 and the second bearing 12. The rotating ventilation shaft 310 is provided with a flyer fork shaft mounting hole 311 that axially passes through the rotating ventilation shaft 310 to rotatably assemble the flyer fork shaft 320. To achieve this rotational assembly, a third bearing 13 and a fourth bearing 14 may be respectively assembled in the flyer fork mounting hole 311 to rotatably assemble the flyer fork shaft 320 through the cooperation of the third bearing 13 and the fourth bearing 14. The pneumatic wire clamping mechanism 330 may be specifically fixed on the rotating ventilation shaft 310, and the clamping head 331 of the pneumatic wire clamping mechanism 330 is arranged adjacent to the product top block 321 of the flyer fork shaft 320. In order to better fix the pneumatic wire clamping mechanism 330, a fixed seat 312 may be provided at the bottom end of the rotating ventilation shaft 310 to support and fix the pneumatic wire clamping mechanism 330. When performing the coil winding operation, the product top block 321 of the flying fork shaft 320 may be fixed with a magnetic core product that needs to be coil wound (such as a magnetic core inductor, the magnetic core product can be clamped by another mechanism and driven to rotate synchronously with the flying fork shaft, that is, when the flying fork shaft rotates clockwise at a speed V, the other mechanism also clamps the magnetic core product and drives the magnetic core product to rotate clockwise at a speed V, so that the two remain in a relatively static state), and the pneumatic wire clamping mechanism 330 clamps the wire used for coil winding (specifically, it can be a copper wire). Therefore, during the coil winding process, the rotating ventilation shaft 310 needs to rotate within the corresponding flyer mounting hole 120 to drive the corresponding wire to rotate around the corresponding magnetic core product, and the flyer shaft 320 needs to rotate within the corresponding flyer shaft mounting hole 311 to maintain a relatively static state with the abutted and fixed magnetic core product. Since the two rotate in the same direction, in order to allow the wire to be wound around the corresponding magnetic core product, the rotation speeds of the two need to maintain a certain difference. For example, the rotating ventilation shaft 310 generally winds the wire at a speed of 2V with the pneumatic wire clamping mechanism 330, while the flyer shaft generally rotates synchronously with the abutted and fixed magnetic core product at a speed of V. Therefore, the power mechanism 200 can specifically drive the rotating ventilation shaft 310 and the flyer shaft 320 to respectively drive the rotating ventilation shaft 310 to rotate within the corresponding flyer mounting hole 120 and drive the flyer shaft 320 to rotate within the corresponding flyer shaft mounting hole 311. In addition, since the winding of the magnetic core product needs to be wound in two layers, and the magnetic core product is generally a T-shaped structure, when the blades on both sides of the magnetic core product are clamped and fixed by another mechanism and driven to rotate, and the bottom of the magnetic core product is in contact with the product top block 321 of the flying fork shaft 320, the product top block 321 can play a certain limiting role in the winding at the bottom of the magnetic core product, so as to prevent the winding from derailing and damaging the magnetic core product when the pneumatic clamping mechanism 330 is winding the lower layer of the magnetic core product.

[0030] In some examples, such as Figures 1 to 4 As shown, the pneumatic wire clamping mechanism 330 includes a clamp 331 and a power cylinder 332 that drives the clamp 331 to close or separate. Specifically, in the present embodiment, the power cylinder 332 drives the clamp 331 to close or separate, thereby achieving the corresponding wire clamping operation. However, as is well known, the power cylinder 332 must be connected to an air pipe for ventilation in order to operate the pneumatic actuator. In ordinary applications, the air pipe layout does not need to be considered, and the air pipe will not become entangled. However, in applications where the actuator needs to rotate, the air pipe layout must be considered to avoid entanglement and suffocation.

[0031] To this end, in some examples, such as Figures 1 to 5 As shown, the rotary vent shaft 310 has a built-in gas passage 314, the outlet of which connects to the drive gas passage 314 of the power cylinder 332 (not shown). At least one inlet 313 for the gas passage 314 is provided in the portion of the rotary vent shaft 310 located in the transition hole section 122. Furthermore, the transition hole section 122 is equipped with at least one rotary shaft seal assembly 400 with a gas pipe connector 410. This creates a sealed gas path between the inlet 313 of the gas passage 314 and the rotary shaft seal assembly 400, while not hindering the rotation of the rotary vent shaft 310 within the corresponding flyer mounting hole 120. This allows the corresponding drive gas to be introduced into the sealed gas path through the gas pipe connector 410. This drive gas then enters the gas passage 314 within the rotary vent shaft 310 through the inlet 313 within the sealed gas path. This eliminates the need for an additional gas pipe connection between the rotating component (i.e., the rotary vent shaft 310) and the fixed component (i.e., the rotary shaft seal assembly 400), effectively preventing the possibility of gas pipe entanglement and suffocation. Finally, the driving gas entering the gas passage 314 can be guided through the gas passage 314 to the driving gas passage of the power cylinder 332 connected to the outlet of the gas passage 314. Since the power cylinder 332 is fastened to the rotating ventilation shaft 310 and rotates synchronously with the rotating ventilation shaft 310, the power cylinder 332 and the rotating ventilation shaft 310 maintain a relatively static state. The outlet of the gas passage 314 can be directly connected to the driving gas passage of the power cylinder 332, or it can be connected to the driving gas passage of the power cylinder 332 through the air pipe, and the air pipe will not be entangled and suffocated.

[0032] In some examples, such as Figures 1 to 5As shown, the rotary shaft seal assembly 400 includes a first shaft seal 420, a second shaft seal 430, and a shaft seal mounting base 440 with an air pipe connector 410. The shaft seal mounting base 440 is fixed to the sidewall of the transition hole section 122. A through hole 1221 is defined in the sidewall of the transition hole section 122 to expose the air pipe connector 410. The first shaft seal 420 is mounted between the upper portion of the shaft seal mounting base 440 and the rotary vent shaft 310, while the second shaft seal 430 is mounted between the lower portion of the shaft seal mounting base 440 and the rotary vent shaft 310. This creates a sealed air path between the middle portion of the shaft seal mounting base 440 and the inlet 313 of the gas passage 314. The first shaft seal 420 and the second shaft seal 430 may specifically each include at least one sealing ring. The first shaft seal 420 and the second shaft seal 430 may seal the gap between the shaft seal mounting seat 440 and the outer wall of the rotary ventilation shaft 310 to form a closed gas path between the first shaft seal 420 and the second shaft seal 430 and between the middle part of the shaft seal mounting seat 440 and the outer wall of the rotary ventilation shaft 310. The inlet 313 of the gas path 314 faces the middle part of the shaft seal mounting seat 440, and the inlet 313 of the gas path 314 is located in the closed gas path. The air pipe joint 410 is externally connected to a driving gas input pipeline (not shown), and the air pipe joint 410 is internally connected to the closed gas path, that is, the air pipe joint 410 is arranged corresponding to the middle part of the shaft seal mounting seat 440 to pass the driving gas into the sealed gas path. In order to achieve a better rotary sealing effect and ensure that more driving gas enters the driving air path of the power cylinder 332, the rotary ventilation shaft 310 of the present application is equipped with two gas passages 314. The inlets 313 of the two gas passages 314 are located at different heights of the rotary ventilation shaft 310, and the inlets 313 of the two gas passages 314 are staggered up and down. The transition hole section 122 is equipped with two rotary shaft seal assemblies 400 to form a closed air path between the inlet 313 of each gas passage 314 and the corresponding rotary shaft seal assembly 400.

[0033] In some examples, such as Figure 1 and Figure 3As shown, the power mechanism 200 may specifically include a plurality of first power motors 210, and the plurality of first power motors 210 are arranged in one-to-one correspondence with the plurality of winding fork assemblies 300. A first driving pulley 220 is fixedly provided on the motor shaft of the first power motor 210, and a first driven pulley 230 is fixedly provided on the rotating ventilation shaft 310 of the winding fork assembly 300. The first driving pulley 220 and the corresponding first driven pulley 230 are connected for transmission via a first synchronous belt 240, so as to drive the rotating ventilation shaft 310 of the corresponding winding fork assembly 300 to rotate in the corresponding fork mounting hole 120 through the first power motor 210. Since the rotating ventilation shaft 310 of each winding flyer fork assembly 300 must form a closed air path space while rotating, a rotating shaft seal assembly 400 will be used. The friction force is very large and cannot be quantified. If only one power motor is used to drive and add tension through the synchronous belt tensioning, not only will the load on the power motor be greater, causing the power motor to heat up and overload, but it will also make it inconvenient to debug the individual rotation of each rotating ventilation shaft, and cause the synchronous belt to be stripped and lost at high speeds due to the high load. In this example, the above situation can be effectively avoided by driving the rotating ventilation shaft 310 of the corresponding winding flyer fork assembly 300 to rotate in the corresponding flyer fork mounting hole 120 through multiple first power motors 210 one by one.

[0034] In some examples, such as Figure 1 and Figure 3 As shown, the power mechanism 200 may further include a second power motor 250, a second driving pulley 260 is fixedly provided on the motor shaft of the second power motor 250, a second driven pulley 270 is fixedly provided on the flying fork shaft 320 of the winding flying fork assembly 300, and the second driving pulley 260 and the second driven pulley 270 on the flying fork shaft 320 of multiple winding flying fork assemblies 300 are connected for transmission via a second synchronous belt 280, so as to drive the flying fork shaft 320 of each winding flying fork assembly 300 to rotate in the corresponding flying fork shaft mounting hole 311 through the second power motor 250. Since the flying fork shaft 320 of each winding flying fork assembly 300 and the corresponding flying fork shaft mounting hole 311 are only used in conjunction with bearings, the friction force is negligible. Therefore, the solution of using a power motor in this example to simultaneously drive the flying fork shaft 320 of each winding flying fork assembly 300 to rotate in the corresponding flying fork shaft mounting hole 311 can effectively reduce the complexity of its power mechanism 200 while meeting its power requirements.

[0035] In some examples, in order to better support and fix the power mechanism 200, as shown in FIG. Figure 1 、 Figure 2 and Figure 3As shown, the frame 100 can also specifically include a base 130, a motor mounting plate 140 and two vertical plates 150. The two vertical plates 150 are relatively fixed on the base 130, and the two vertical plates 150 are respectively connected with a flying fork mounting seat 110 and a motor mounting plate 140. Multiple first power motors 210 are installed and fixed on the motor mounting plate 140 in sequence, and the second power motor 250 is installed and fixed on any vertical plate 150.
