Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a carbon fiber winding device for an axial flux motor rotor disk. Background Art

[0002] In existing technology, the outer surface of the rotor core is wound with carbon fibers to enhance its strength. During the winding process, the winding equipment must apply a certain amount of tension to the carbon fibers to ensure that the wound carbon fibers form an appropriate preload on the rotor core. This preload is crucial to rotor performance: if the preload is too high, the rotor core may yield under the pressure in a static state; if the preload is too low, the core may yield or even break under tension when the rotor rotates at high speeds.

[0003] Typically, during the production process, the required tension applied by the winding equipment is calculated based on the mechanical model of the carbon fiber. However, due to the lack of real-time feedback, the final carbon fiber preload still has the risk of being too high or too low. In addition, the rotor core structure of the built-in magnetic steel is complex. Even cores with the same outer diameter may experience significant differences in the preload. This feature makes it unreliable to rely solely on mechanical model calculations to control preload during production. Existing technologies are unable to monitor the pressure inside the carbon fiber in real time during production, making it difficult to accurately grasp the relationship between the tension output by the winding equipment and the final preload. Therefore, to address the above issues, we propose a carbon fiber winding device for the rotor disk of an axial flux motor. Utility Model Content

[0012] Preferably, the gluing assembly includes three gluing rotors, and the three gluing rotors are arranged side by side in parallel.

[0013] Preferably, the gluing mechanism further includes a gluing tank for containing glue liquid.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0021] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0022] The utility model provides a carbon fiber winding device for the rotor disk of an axial flux motor. Figures 1-2 , including a wire passing mechanism 1, the wire passing mechanism 1 includes a carbon fiber supply roller 101, a wire reel 102 arranged on one side of the carbon fiber supply roller 101, a control component 103 arranged on one side of the wire reel 102, and a plurality of wire rings 104 arranged on one side of the control component 103; a gluing mechanism 2, used to evenly apply glue to the carbon fiber before the carbon fiber winding process; a winding mechanism 3, used for winding the carbon fiber.

[0023] The gluing mechanism 2 includes a correction wheel 201 arranged on one side of the wire ring 104, a gluing component 202 arranged on one side of the correction wheel 201, a glue pressing roller 203 arranged on one side of the gluing component 202, and a wire outlet roller 204 arranged on one side of the glue pressing roller 203; the winding mechanism 3 includes a guide wheel group 301 arranged on one side of the glue pressing roller 203, and a winding roller 302 arranged on one side of the guide wheel group 301.

[0024] The control component 103 includes a tensioner roller 103a and a pair of control pulleys 103b on both sides of the tensioner roller 103a; the tension applied during carbon fiber transportation is adjusted by adjusting the height of the control pulleys 103b on both sides; the gluing component 202 includes three gluing rotors 202a, which are arranged side by side in parallel; the gluing mechanism 2 also includes a gluing tank 205 for containing glue.

[0025] It should be noted that carbon fiber is a high-performance fiber material with carbon as its main component. It has excellent properties such as high strength, high rigidity, low density and high temperature resistance. Carbon fiber can not only withstand large mechanical stress, but also maintain stable performance under high temperature and harsh environment. In the carbon fiber winding device of the axial flux motor rotor disk, carbon fiber is usually used as a reinforcing material to improve the strength and stiffness of the rotor disk, reduce weight, and thus improve the overall performance and efficiency of the motor.

[0026] Preferably, the carbon fiber starts from the carbon fiber supply roller 101 and passes through the wire passing mechanism 1, the gluing mechanism 2, the winding mechanism 3 in sequence, and finally ends at the winding roller 302. The wire passing mechanism 1 outputs torque tension and the winding mechanism 3 outputs rotation speed, so that the carbon fiber has a certain tension.

[0027] Preferably, under the action of tension, the carbon fiber after being wound around the rotor or roller will have a certain pre-pressure on its surface, and the size of the pre-pressure is difficult to control. Therefore, before use, the winding roller 302 of the device is often replaced with a test cylinder to detect the pressure of the carbon fiber wound on the test cylinder, so as to monitor and control the pre-pressure in real time and control the tension of the carbon fiber by controlling the control wheel 103b through the control component 103.

[0028] Preferably, the tensioner roller 103a is fixed, and the tensioning force of the carbon fiber during transmission can be changed by adjusting the position and height of the control pulleys 103b on both sides. The position of the control pulley 103b is changed by a servo motor. The servo motor has a pair of control pulleys 103b on both sides respectively. During adjustment, fine-tuning is generally adopted to gradually adjust until the pre-pressure on the test cylinder meets the requirements of the rotor carbon fiber winding operation.

[0029] Preferably, there are three gluing rotors 202a, and the carbon fiber enters the first gluing component 202 through the correction wheel 201. The carbon fiber first passes under the first gluing rotor 202a, then passes around the second gluing rotor 202a from above, and finally passes out from under the third gluing rotor 202a; the carbon fiber is repeatedly and fully glued, and finally the carbon fiber enters the glue pressing roller 203 for rolling after the gluing is completed. While rolling, excess glue is removed and falls into the gluing groove 205 for recycling; the carbon fiber glued out line enters the line outlet roller 204, passes through the guide wheel group 301, and the guide wheel group 301 can calibrate and change the carbon fiber winding angle in real time. The data is transmitted to the controller in real time and the parameters can be set according to the product parameter requirements. The pre-pressure on the test cylinder can be adjusted again by changing the guide angle, thereby achieving more subtle regulation.

[0030] In summary, the carbon fiber winding device for the axial flux motor rotor disk of the utility model replaces the winding roller with a test roller before the production process to monitor and control the pre-pressure in real time, and controls the pulling force of the control wheel on the carbon fiber through the control component. The torque output by the wire-passing mechanism and the speed output by the winding mechanism are adjusted according to the detection results, and the guide wheel group is linked to fine-tune the carbon fiber winding guide angle so that the final pre-pressure of the carbon fiber on the rotor is within a reasonable range, and finally the rotor carbon fiber winding operation requirements are met.

[0031] The above description is only a description of the preferred embodiment of the present invention and does not limit the scope of the present invention. Any changes and modifications made by ordinary technicians in the field of the present invention based on the above disclosure shall fall within the scope of protection of the claims.
