It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0047] It should be noted that when a component is referred to as "set on" or "connected to" another component, it can be directly on or indirectly on that other component. When a component is referred to as "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0048] It should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] The terms "first" and "second" are used for descriptive purposes only and are not intended to imply relative importance.

[0050] In existing technologies, the processing of transformers, reactors, and other products requires winding the iron core, and the winding tension needs to be controlled during this process. Manual judgment and control methods cannot achieve precise control of the winding tension, thus affecting the processing quality of transformers, reactors, and other products.

[0051] To solve the above problems, this utility model provides a winding system.

[0052] refer to Figures 1 to 2 This is a schematic diagram of the winding system provided by this utility model.

[0053] The main components of the winding system are all mounted on the frame 1. The frame 1 can be an integral structure or a multi-component splicing and assembly structure.

[0054] The frame is equipped with a core fixing mechanism, including a drive shaft 4 and a motor (not visible in the figure). The motor is electrically connected to the drive shaft, and the core to be wound can be placed on the drive shaft 4 and rotate with the drive shaft 4. The output frequency of the motor determines the rotational speed of the drive shaft 4.

[0055] There are many types of transformer cores, and the winding device provided by this invention can be used for toroidal cores, columnar cores, and other types of cores. These cores have a central hole, which can be fitted onto the drive shaft 4. The dimensions of the drive shaft 4 can be designed according to the dimensions of the core's central hole.

[0056] The frame 1 is equipped with a wire feeding structure, including a winding reel for winding the wire core to be wound. It should be understood that the wire core is the wire wound around the outside of the transformer or reactor. The winding reel includes a main reel 201 and a guide reel 202. In this embodiment, the main reel 201 is larger than the guide reel 202, and the guide reels 202 are arranged around the main reel 201 to guide the wire core to the position of the iron core according to its location.

[0057] A tension detection mechanism is installed on frame 1 to detect the tension of the wound wire core. It should be understood that the tension of the wound wire core determines its tightness when wound around the iron core, which affects the product's performance. The tension detection mechanism includes a tension wheel 301 and a tension gauge 302 mounted on frame 1. The wire core to be wound is wound onto the iron core via the tension wheel 301, and the tension gauge 302 is connected to the tension wheel 301 to detect the tension of the wire core passing through the tension wheel. Figure 1 As shown, the tension gauge 302 serves as the base, and tension reels 301 are positioned on top of the tension gauge 302. There can be one or more tension reels 301, and the height of each reel 301 can be the same or different. In this embodiment, there are three tension reels 301, with the middle one serving as the main reel and the two on either side as auxiliary reels. The main reel is higher; after the wound yarn passes through the main reel, downward pressure is applied to it, and this pressure reflects the tension of the wound yarn. The tension gauge 302 can detect the tension through this pressure. The tension gauge 302 is equipped with a display screen 3021, which can display the detected tension value. The auxiliary reels on both sides of the main reel mainly serve as auxiliary guides.

[0058] The controller connects to the motor and tension sensor 302.

[0059] In this embodiment, a tension detection mechanism 302 is configured in the winding structure. The tension detector 302 can detect the winding tension of the winding core. This tension can be displayed in real time and transmitted to the controller, which can then output a control signal to the motor based on the real-time tension, adjusting the motor's output frequency. The higher the motor's output frequency, the more it can control the rotation of the spindle, thereby controlling and adjusting the tension of the winding core through the rotation speed of the iron core.

[0060] In some embodiments of this invention, a human-machine control unit 7 is further included. The human-machine control unit 7 is mounted on the frame 1 and includes a touch screen, capable of sending control commands to the controller via the touch screen. The motor can adjust the speed output of the drive shaft 4 according to the sent control commands.

[0061] In some embodiments of this utility model, in order to fix the iron core more stably, the iron core fixing mechanism also includes an auxiliary clamping device, which includes a telescopic rod 5, which is arranged in the direction of the drive shaft 4.

[0062] In some embodiments of this utility model, the auxiliary clamping device employs a pneumatic cylinder or an electric cylinder. Taking a pneumatic cylinder as an example, the cylinder rod acts as a telescopic rod, capable of operating in the direction of the drive shaft 4. Figure 1 As shown, the frame 1 includes an auxiliary clamping device mounting base 6, and a cylinder is mounted on the auxiliary clamping device mounting base 6. Before winding, the cylinder rod retracts to fix the iron core onto the drive shaft 4. After fixing, the cylinder rod extends and works together with the drive shaft 4 to clamp the iron core.

[0063] In this embodiment, the telescopic rod 5 and the drive shaft 4 work together to ensure that the iron core can be clamped during the winding process.

[0064] In some embodiments of this utility model, to solve the problem of installing the wire feeding structure, the wire feeding structure includes a mounting plate 203 disposed on the frame, and winding reels disposed on the surface of the mounting plate 203, that is, both the main reel 201 and the guide reel 202 are disposed on the surface of the mounting plate 203. Figure 1 As described above, the mounting plate 203 is vertically mounted on the frame 1. The main cable wheel 201 and the guide cable wheel 202 are arranged horizontally and vertically, respectively, depending on the cable routing direction requirements.

[0065] In some embodiments of this utility model, winding wheels are provided on both surfaces of the mounting plate 203. (See reference) Figure 2 Multiple main wire wheels 201 and guide wire wheels 202 are provided on both sides of the mounting plate 203. This structure provides a multi-wire source winding structure, which enables multiple iron cores or different parts of the iron core to be wound at the same time.

[0066] In some embodiments of this utility model, a plurality of mounting plates 203 are arranged at intervals. Correspondingly, a plurality of main wire pulleys 201 and guide wire pulleys 202 are provided on one or both sides of each mounting plate 203. Compared with the aforementioned real-time method, this structure further increases the number of winding wire sources, thereby improving the efficiency of winding processing.

[0067] In some embodiments of this utility model, a travel rail 8 is provided on the frame 1, and the bottom of each mounting plate 203 is mounted on the travel rail 8 via a slider 204.

[0068] By mounting the mounting plate 203 on the traveling rail 8, the position of a single mounting plate 203 can be adjusted, or the relative positions of multiple mounting plates 203 can be adjusted, which facilitates the adjustment of the winding position along the length of the iron core.

[0069] To improve the stability of the mounting plate 203, two parallel travel rails 8 can be designed, and two sliders 204 can be set at the bottom of each mounting plate 203, with each slider 204 mounted on one travel rail 8.

[0070] In some embodiments of this utility model, the tension detection mechanism comprises multiple sets, spaced apart on the frame 1. (See reference) Figure 1 and Figure 2 In this embodiment of the utility model, four sets of tension detection mechanisms are included. Correspondingly, two mounting plates 203 can be set, and a main line wheel 201 and a guide line wheel 202 are respectively set on two sides of each mounting plate 203.

[0071] The structure of multiple tension detection mechanisms and multiple mounting plates is matched. Each tension detection mechanism corresponds to a set of winding wire sources, which is used to detect the winding tension of a set of winding wire sources. In this way, the tension of each set of winding wire sources can be adjusted in a targeted manner, or the winding tension of each set of winding wire sources can be ensured to be balanced.

[0072] In some embodiments of this utility model, the winding system further includes a guide assembly disposed between the core fixing mechanism and the wire feeding structure. The guide assembly includes a guide bracket 901 and a guide wheel 902 mounted on the guide bracket 901. (See reference...) Figure 1 In this embodiment of the application, the guide component is disposed between the tension detection mechanism and the iron core fixing mechanism. Alternatively, the guide component can also be disposed between the wire feeding structure and the tension detection mechanism. Through the guide wheel structure, the winding direction of the winding core output by the wire feeding structure can be easily adjusted.

[0073] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
