Description

Technical Field

[0001] This utility model relates to a rotor winding machine, belonging to the technical field of rotor processing equipment. Background Technology

[0002] Before assembling the stator and rotor of an electric motor, a layer of glass fiber is typically wound around the rotor's surface to improve its performance stability. This enhances fatigue resistance and structural rigidity without significantly improving overall weight. Traditional rotor winding equipment involves manually loading the rotor and then coating its surface with a curable resin. This resin adheres to the glass fiber during winding and fixes its position. After winding, the resin is heated and cured to create the desired rotor. However, in smaller, single-person operating systems, the rotor must be manually positioned before applying the resin. This process can result in inconsistent resin coating and is susceptible to sedimentation due to gravity, making the operation cumbersome and unreliable for ensuring good rotor winding quality. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rotor winding machine that automatically adheres resin material to the surface of the rotor during the rotor winding process, eliminating the need for manual coating and better ensuring the quality of the rotor.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] This utility model provides a rotor winding machine, including a worktable. A bottom mold, a first driving device for driving the bottom mold to rotate, a top mold assembly, a threading mechanism, and a sol-gel mechanism are rotatably mounted on the worktable. The bottom mold is used to fix the bottom of the rotor. The top mold assembly includes a first lifting mechanism and an abutting component mounted on the first lifting mechanism. The abutting component can approach the bottom mold and abut against the top of the rotor under the drive of the first lifting mechanism. The threading mechanism and the sol-gel mechanism are relatively fixedly arranged and both are fixedly mounted on the output end of the second lifting mechanism. The sol-gel mechanism has a hollow tube structure, and the interior of the hollow tube structure is filled with a gel-like substance. The threading mechanism is used to thread glass fibers through the hollow tube structure of the sol-gel mechanism. The gel-like substance can be cured by heating or by ultraviolet radiation.

[0006] Specifically, the sol-gel mechanism is equipped with a glue supply tank, and the glue outlet of the glue supply tank is connected to the hollow tube part inside the sol-gel mechanism.

[0007] Specifically, a piston plate capable of squeezing the glue inside the glue supply tank is configured above the glue supply tank, and the second lifting mechanism is also provided with a second driving device for driving the piston plate to rise and fall.

[0008] Specifically, the sol mechanism is equipped with a heating component for heating the glue inside the hollow tube structure of the sol mechanism.

[0009] Specifically, the abutting component includes a limiter and an abutting rod. The limiter has an ellipsoidal receiving space inside. Both the upper and lower ends of the ellipsoidal receiving space are provided with through holes that penetrate the limiter vertically. The abutting rod includes a limiting part and an abutting part. The limiting part has an ellipsoidal structure located within the ellipsoidal receiving space. The edge of the limiting part has a vertical tangent centered on the vertical central axis. The diameter of the tangent centered on the edge of the ellipsoidal structure matches the diameter of the through hole located above the limiter. A limiting member is provided above the limiter to abut the limiting part.

[0010] Specifically, the limiting component includes a limiting plate and an elastic pad disposed below the limiting plate. The limiting plate is provided with a pressure sensor for detecting the pressure applied by the abutment rod to the limiting plate.

[0011] Specifically, the workbench is also equipped with a curing device for curing the adhesive, which is used to heat the sides of the rotor.

[0012] Specifically, the workbench is also equipped with a curing device for curing the adhesive, which is used to irradiate the sides of the rotor with UV light.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0014] This invention sets up a corresponding sol mechanism on the fiberglass threading path so that the surface of the fiberglass is coated with a corresponding resin material when it exits the sol mechanism. The rotation of the bottom mold assembly drives the positioned rotor to automatically wind the fiberglass. This allows the fiberglass to have a certain degree of adhesion to the outer surface of the rotor while winding, eliminating the need for additional manual coating of the rotor's outer surface. This simplifies the workload and prevents product defects caused by uneven resin distribution due to gravity. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example:

[0024] This utility model provides a rotor winding machine for automatically adhering resin material to the surface of the rotor during the rotor winding process. This eliminates the need for manual coating and better ensures rotor quality. To achieve the structural function of the device, it includes a workbench 1, as shown below. Figure 1 As shown, a bottom mold 2, a first driving device 3 for driving the bottom mold 2 to rotate, a top mold assembly 4, a threading mechanism 5, and a sol-gel mechanism 6 are rotatably mounted on the workbench 1. The first driving device 3 can use belt drive to control the rotation of the bottom mold 2. The bottom mold 2 is used to fix the bottom of the rotor and is adapted to fit a rotor of a corresponding model. The top mold assembly 4 includes a first lifting mechanism 401 and an abutting component 402 disposed on the first lifting mechanism 401. The abutting component 402 can approach the bottom mold 2 and abut against the top of the rotor under the drive of the first lifting mechanism 401. In some other embodiments, such as... Figure 1 As shown, the first lifting mechanism 401 can be used to control the long stroke of the abutment component 402. Specifically, the descent of the abutment component 402 can be controlled by an additional linear motion mechanism, such as using a cylinder and guide rod to perform the corresponding action. In order to ensure that the glass fiber is evenly distributed on the surface of the rotor in the vertical direction during the rotor rotation, the threading mechanism 5 and the sol-gel mechanism 6 are set to be fixedly arranged and both are fixedly arranged on the output end of the second lifting mechanism 7. The sol-gel mechanism 6 is used to provide the resin material for the adhesive, such as epoxy resin or polyurethane resin. In order to achieve the adhesion of the adhesive material during the threading of the glass fiber, the following is set: The sol mechanism 6 has a hollow tube structure filled with a gel-like substance. The threading mechanism 5 guides the exit position of the glass fiber, allowing it to pass through the hollow tube structure of the sol mechanism 6 and stabilize the exit path of the glass fiber. The specific structure is not limited here, as long as it can achieve the corresponding function. The gel-like substance can be cured by heating or by ultraviolet irradiation. By filling the hollow tube structure with this gel-like substance, the glass fiber is guided to pass through from the inside. The glass fiber, along with the resin, adheres to the surface of the rotor and is then cured. There is no need to manually coat the rotor with resin, thus simplifying the working process while ensuring uniform adhesion of the resin.

[0025] This utility model provides a rotor winding machine. Considering the need to ensure the supply of curing materials such as resin within the hollow tube structure, a glue supply tank 8 can be installed on the sol-gel mechanism 6. The glue outlet of the glue supply tank 8 is connected to the hollow tube portion inside the sol-gel mechanism 6. To automatically supply glue to the hollow tube structure when glue is insufficient, in addition to configuring an additional sensor to detect the glue quantity, a piston plate capable of squeezing the glue inside the glue supply tank 8 can be configured above it. The second lifting mechanism 7 is also equipped with a second driving device (not shown in the figure) for driving the piston plate to rise and fall. This second driving device can be a hydraulic push rod or a pneumatic valve; the specific means are not unique and will not be elaborated upon here.

[0026] The present invention provides a rotor winding machine. When the colloid material is thermoplastic resin, in order to ensure its molten state adhesion to the glass fiber, a heating component for heating the glue inside the hollow tube structure of the sol mechanism 6 can be provided on the sol mechanism 6. The heating component can be a common electric heating structure.

[0027] This utility model provides a rotor winding machine. Considering that when the first lifting mechanism (401) controls the lowering of the abutment component 402 to clamp the rotor, if the rotor's placement is incorrect, it is difficult to ensure proper engagement of the rotor's top end. To reduce the impact of this slight tilt, the abutment component 402 can be configured to include a limiter 4021 and an abutment rod 4022. Figures 2-4 As shown, an ellipsoidal receiving space is provided inside the limiter 4021. Through holes are provided at both the upper and lower ends of the ellipsoidal receiving space, penetrating the limiter 4021 vertically. An abutment rod 4022 is provided, including a limiting part and an abutment part. The limiting part has an ellipsoidal structure located within the ellipsoidal receiving space. A vertically tangent edge is formed on the edge of the limiting part, with the vertical central axis as its axis. The diameter of the tangent edge matches the diameter of the through hole located above the limiter 4021. Within this ellipsoidal receiving space, the ellipsoidal structure can rotate freely within the limiter 4021, thereby... The contact end of the abutment rod 4022 is provided with a corresponding amplitude variation range, so that after the rotor is pre-fixed, the position of the abutment rod 4022 can be manually adjusted slightly to align it with the top of the rotor. Under the pressure of the first lifting mechanism 401, the ellipsoidal structure will rise and fit with the through hole, ensuring the straightness of the abutment rod 4022 in the vertical direction and avoiding the rotor from swaying due to misalignment of the upper and lower fixing points. To prevent the end of the abutment rod 4022 from dislodging from the limiter 4021, a limit member 4023 can be provided above the limiter 4021 for contacting the limiter part. As a preferred embodiment, to avoid rigid contact of the structure caused by mechanical hard contact during rotor clamping, the limit member 4023 includes a limit plate and an elastic pad provided below the limit plate. To control the reasonable clamping force on the rotor, a pressure sensor can be provided on the limit plate to detect the pressure applied by the abutment rod 4022 to the limit plate.

[0028] This utility model provides a rotor winding machine. To facilitate the curing of the adhesive material attached to the glass fiber surface after the rotor winding machine is completed, a curing device (not shown in the figure) for curing the adhesive can be directly provided on the worktable 1. For thermosetting resins, the curing device can be a device for heating the sides of the rotor, such as infrared heating or electrothermal radiation heating. For some UV adhesives, the curing device can be a device for irradiating the sides of the rotor with UV light, achieving curing and adhesion of the adhesive through ultraviolet curing. Since the rotor can rotate continuously on the worktable 1, both the heating device and the ultraviolet curing device can be set as vertically extending strips, used to act on the circumference of the rotor during rotation.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
