Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically a precision positioning coating machine for wrapping electromagnetic wires with glass fiber film. Background Technology

[0002] In the production process of glass fiber wrapped with film to wrap electromagnetic wire, a wrapping machine is needed to achieve precise wrapping of the electromagnetic wire by the film and glass fiber. However, existing wrapping equipment often has many problems.

[0003] On the one hand, the winding structure lacks stability, and the winding reel used to hold the uncoated enameled wire is prone to shifting during unwinding. Furthermore, the rotation speed of the winding reel is difficult to control, and the enameled wire is prone to loosening due to excessive speed, affecting the coating accuracy. On the other hand, the replacement process for the components used to wind and coat the enameled wire is complicated, requiring the disassembly of multiple connecting structures, which is time-consuming and reduces production efficiency.

[0004] On the other hand, some equipment lacks an effective tension adjustment structure, or the adjustment components are poorly compatible with the winding reel, which can easily lead to localized wear and uneven pressure. This not only affects the quality of the electromagnetic wire coating but may also shorten the equipment's service life, making it difficult to meet the demand for efficient and precise electromagnetic wire coating production. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a precision positioning and wrapping machine for wrapping electromagnetic wires with glass fiber-coated film, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A precision positioning coating machine for wrapping electromagnetic wire with glass fiber-coated film includes: A base plate and a fixing frame, wherein the fixing frame is disposed on the top of the base plate; The main body of the coating machine is located on the outside of the fixed frame; The winding reel is provided with a bolt and a nut. The winding reel is disposed between the fixing frame and the fixing frame. The bolt passes through the interior of the winding reel and the fixing frame. The nut is threadedly connected to the bolt to fix the winding reel. The system includes a support plate, an arc-shaped plate, a spring, a limiting plate, and pressure rods. The support plate is located on the outer side of the base plate. Two arc-shaped plates are fixedly installed on the top outer side of the support plate. The spring is fixedly installed on the outer side of the support plate. The limiting plate is fixedly installed on the top of the spring and fits against the outer side of the winding reel. Two pressure rods are fixedly installed on both sides of the limiting plate. The motor, clamping plates, bolt two, and nut two are provided. The motor is fixed to the outside of the base plate by a stabilizing plate. The two clamping plates are fixedly installed at the output end of the motor. Bolt two passes through the interior of the two clamping plates. Nut two is threadedly connected to bolt two. The device includes a rotating shaft and a second winding reel, wherein the rotating shaft is engaged inside the fixed frame, and the second winding reel is fixedly sleeved on the outside of the rotating shaft.

[0007] Preferably, the contact surface between the limiting plate and the first winding reel is arc-shaped, and the arc curvature matches the outer arc curvature of the first winding reel.

[0008] Preferably, the length of the first bolt is greater than the sum of the thicknesses of the fixing frame and the first winding reel, and the inner diameter of the first nut is adapted to the outer diameter of the first bolt.

[0009] Preferably, the output end of the motor is connected to the rotating shaft for transmission, and when the motor starts, it can drive the rotating shaft and the winding reel to rotate synchronously.

[0010] Preferably, when the spring is in its natural state, the limiting plate is in close contact with the outer side of the first winding reel; when the spring is in its compressed state, the squeezing force of the limiting plate on the first winding reel increases.

[0011] Preferably, the outer diameter of the rotating shaft is adapted to the inner diameter of the engagement hole of the fixing frame, and the rotating shaft can be pulled out from the engagement hole of the fixing frame to replace the second winding reel.

[0012] Preferably, the axes of the first winding reel and the second winding reel are on the same horizontal plane to ensure that the electromagnetic wire between them remains horizontally taut.

[0013] Preferably, the arc-shaped plates are symmetrically distributed on both sides of the top of the support plate, and the height of the arc-shaped plates is lower than the height of the limiting plate, so as to avoid interfering with the movement of the limiting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This glass fiber film-wrapping electromagnetic wire uses a precision positioning wrapping machine, ensuring stable wrapping quality: The motor drives the second winding reel to rotate at a uniform speed, while a spring-driven limit plate adheres to the first winding reel to increase rotational resistance. This prevents the electromagnetic wire from loosening due to excessive rotation of the first winding reel. Furthermore, the axes of the first and second winding reels remain horizontal, ensuring that the electromagnetic wire is always taut. This provides stable conditions for the main body of the wrapping machine to accurately wrap the glass fiber film, effectively improving the wrapping quality of the electromagnetic wire.

[0015] 2. This glass fiber coated film wrapping electromagnetic wire uses a precision positioning wrapping machine with a reliable and fixed structure: the take-up reel is locked to itself by a bolt through the fixing frame and a nut. The bolt is of suitable length and the inner diameter of the nut matches the outer diameter of the bolt, which can firmly fix the take-up reel and prevent it from shifting during the unwinding process; the motor is fixed to the base plate by a stabilizing plate, and the output end clamping plate is connected to the nut by bolts to form a stable transmission structure, ensuring stable power transmission. The overall structure is highly fixed, reducing the risk of failure during equipment operation.

[0016] 3. This glass fiber film-wrapped electromagnetic wire precision positioning wrapping machine is easy and efficient to operate: When replacing the second take-up reel, only the second bolt and the second nut need to be removed to pull the shaft out of the fixed frame, and the replacement of the second take-up reel can be completed quickly without complicated disassembly procedures, which greatly shortens the replacement time and improves the continuous operation efficiency of the equipment; the limit plate is equipped with pressure rods on both sides, which can adjust the pressure of the limit plate on the first take-up reel according to actual needs, making the operation flexible and convenient.

[0017] 4. This glass fiber-coated film wrapping electromagnetic wire uses a precision positioning wrapping machine with excellent adaptability and safety: the surface of the limiting plate that fits the winding reel is designed to be arc-shaped with a suitable curvature, which maximizes the contact area, makes the pressure evenly distributed, and avoids local wear or insufficient pressure; the arc-shaped plates are symmetrically distributed on the top of the support plate and are lower than the limiting plate, which not only restricts the left and right displacement of the limiting plate, but also does not interfere with its up and down movement. The structural design takes into account both adaptability and safety, and extends the service life of the equipment. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Please refer to the following: Figure 1-4 , A precision positioning coating machine for wrapping electromagnetic wire with glass fiber-coated film includes: The base plate 1 and the fixing frame 2 are located on the top of the base plate 1; The main body 3 of the coating machine is located on the outside of the fixed frame 2; The winding reel 16, bolt 14 and nut 15 are provided. The winding reel 16 is located between the fixing frame 2. Bolt 14 passes through the interior of the winding reel 16 and the fixing frame 2. Nut 15 is threadedly connected to bolt 14 to fix the winding reel 16. The support plate 7, the arc plate 8, the spring 9, the limiting plate 10 and the pressure rod 11 are provided. The support plate 7 is located on the outside of the base plate 1. The two arc plates 8 are fixedly installed on the top outside of the support plate 7. The spring 9 is fixedly installed on the outside of the support plate 7. The limiting plate 10 is fixedly installed on the top of the spring 9 and fits against the outside of the winding reel 6. The two pressure rods 11 are fixedly installed on both sides of the limiting plate 10. Motor 12, clamping plate 13, bolt 2 15 and nut 2 14. Motor 12 is fixed to the outside of base plate 1 by a stabilizing plate. Two clamping plates 13 are fixedly installed at the output end of motor 12. Bolt 2 15 passes through the inside of two clamping plates 13. Nut 2 14 is threadedly connected to bolt 2 15. And a rotating shaft 16 and a second winding reel 17, the rotating shaft 16 being engaged inside the fixing frame 2, and the second winding reel 17 being fixedly sleeved on the outside of the rotating shaft 16; Specifically, firstly, the base plate 1 provides basic support for the entire device, and the fixing frame 2 serves as the core mounting carrier, bearing key components such as the take-up reel 16 and the rotating shaft 16; the uncoated electromagnetic wire is pre-wound onto the take-up reel 16, and bolts 4 pass through the fixing frame 2 and the take-up reel 16, and then the screws are tightened with nuts 5 to fix the take-up reel 16 and prevent it from shifting during the unwinding process; Next, after the electromagnetic wire is led out from the take-up reel 16, it passes through the coating machine body 3 outside the fixed frame 2. During this process, the coating machine body 3 completes the glass fiber wrapping of the electromagnetic wire. The processed electromagnetic wire is wound on the take-up reel 2 17. The take-up reel 2 17 is connected to the rotating shaft 16 by a fixed sleeve, and the rotating shaft 16 is engaged in the fixed frame 2 to ensure stability during winding. The motor 12 is fixed to the outside of the base plate 1 by a stabilizing plate. The two locking plates 13 at its output end form a stable transmission structure by bolt 15 and nut 14, which ensures that the power of the motor 12 can be reliably transmitted to the rotating shaft 16. After the motor 12 is started, the motor 12 drives the rotating shaft 16 to rotate synchronously with the winding reel 17 to achieve the winding of the coated electromagnetic wire. Meanwhile, on the support plate 7 on the outer side of the base plate 1, the spring 9 applies a continuous elastic force to the limiting plate 10, so that the limiting plate 10 fits tightly against the outer side of the take-up reel 6, increasing the rotational resistance of the take-up reel 6 and preventing the electromagnetic wire from loosening due to its rapid rotation caused by inertia; the arc plate 8 at the top of the support plate 7 can help limit the range of motion of the limiting plate 10, and the pressure rods 11 on both sides can facilitate the subsequent adjustment of the position of the limiting plate 10 according to the needs, forming a complete workflow of wire feeding, wrapping, winding, and anti-loosening. In the embodiment: the contact surface between the limiting plate 10 and the take-up reel 6 is arc-shaped, and the arc curvature is adapted to the outer arc curvature of the take-up reel 6. Specifically, the contact surface between the limiting plate 10 and the take-up reel 6 is designed to be arc-shaped, and the arc curvature is perfectly matched with the outer arc curvature of the take-up reel 6, which can maximize the contact area between the two. Compared with flat contact, the larger contact area can make the elastic force applied by the spring 9 evenly distributed on the surface of the take-up reel 6, avoiding the problem of excessive local pressure causing wear of the take-up reel 6, or insufficient local pressure failing to play an effective resistance role, ensuring that the take-up reel 6 always unwinds at a stable speed and maintains the tension of the electromagnetic wire. In the embodiment: the length of bolt 4 is greater than the sum of the thickness of the fixing frame 2 and the winding reel 6, and the inner diameter of nut 5 is adapted to the outer diameter of bolt 4. Specifically, the length of bolt 4 must be greater than the sum of the thicknesses of the fixing bracket 2 and the winding reel 6 to ensure that after bolt 4 passes through both, its end has sufficient length to connect with nut 5. The key to achieving a tight thread engagement is that the inner diameter of nut 5 matches the outer diameter of bolt 4. If the inner diameter is too large, the thread engagement gap will cause the winding reel 6 to loosen during operation. If the inner diameter is too small, assembly may not be possible or the threads may be damaged. Through this dimensional design, bolt 4 and nut 5 can stably lock the winding reel 6, preventing it from shifting axially or radially during unwinding. In this embodiment: the output end of the motor 12 is connected to the rotating shaft 16 for transmission, and when the motor 12 starts, it can drive the rotating shaft 16 and the take-up reel 17 to rotate synchronously. Specifically, the motor 12 serves as a power source, and its output end is directly connected to the rotating shaft 16 via a key connection, coupling, or other means. Although not explicitly mentioned, this can be inferred from functional requirements to ensure that the rotational power of the motor 12 is transmitted to the rotating shaft 16 without loss and synchronously. When the motor 12 starts, the rotating shaft 16 rotates synchronously with the output end of the motor 12, and the winding reel 17 is fixedly mounted on the rotating shaft 16. Therefore, the winding reel 17 will also rotate synchronously with the rotating shaft 16, thereby achieving uniform winding of the coated electromagnetic wire and avoiding unstable winding speed, slack or breakage of the electromagnetic wire due to power transmission delay or slippage. In the embodiment: when the spring 9 is in the natural state, the limiting plate 10 is in close contact with the outer side of the winding reel 6; when the spring 9 is in the compressed state, the squeezing force of the limiting plate 10 on the winding reel 6 increases. Specifically, spring 9 is fixed to the outside of support plate 7. In its natural state, the elastic force of spring 9 can push limit plate 10 to fit tightly against the outside of take-up reel 6. The friction generated at this time can just balance the unwinding inertia of take-up reel 6 and prevent it from rotating too fast. When take-up reel 6 shows abnormal speed due to changes in electromagnetic wire tension, such as an acceleration trend, limit plate 10 can be pressed by pressure rod 11 to compress spring 9. After spring 9 is compressed, its elastic force increases, and the squeezing force of limit plate 10 on take-up reel 6 increases accordingly, further increasing friction, thereby slowing down the speed of take-up reel 6 and ensuring that electromagnetic wire is always kept taut. Conversely, if electromagnetic wire tension is too high, limit plate 10 can be slightly lifted by pressure rod 11 to reduce the compression of spring 9, reduce friction, and prevent electromagnetic wire from being pulled apart. In the embodiment: the outer diameter of the rotating shaft 16 is adapted to the inner diameter of the engagement hole of the fixing frame 2, and the rotating shaft 16 can be pulled out from the engagement hole of the fixing frame 2 to replace the winding reel 2 17. Specifically, the outer diameter of the rotating shaft 16 is matched with the inner diameter of the engagement hole of the fixed frame 2. This ensures that the rotating shaft 16 is stably engaged during the winding process without radial wobbling. When it is necessary to replace the second winding reel 17, the limitation of the motor 12 output end on the rotating shaft 16 can be released by disassembling the second bolt 15 and the second nut 14, and the rotating shaft 16 can be easily pulled out from the engagement hole of the fixed frame 2. After the rotating shaft 16 is pulled out, the second winding reel 17, which is fully wound with electromagnetic wire, can be removed, a new empty second winding reel 17 can be replaced, and then the rotating shaft 16 can be re-engaged into the fixed frame 2 and the second bolt 15 and the second nut 14 can be tightened. This enables the rapid replacement of the second winding reel 17 and improves the continuous operation efficiency of the equipment. In the embodiment: the axes of take-up reel 16 and take-up reel 27 are on the same horizontal plane to ensure that the electromagnetic wire between them remains horizontally taut; Specifically, if the axes of the two are not on the same horizontal plane, the path of the electromagnetic wire from take-up reel 16 to take-up reel 27 will be inclined, resulting in inconsistent tension of the electromagnetic wire at different positions. When the wire is unloaded at a high position and wound up at a low position, the electromagnetic wire may sag due to its own weight; when the wire is unloaded at a low position and wound up at a high position, the electromagnetic wire may be pulled upward, resulting in excessive tension. Designing the axes of the two to be on the same horizontal plane can keep the transmission path of the electromagnetic wire horizontal, and the tension is evenly distributed throughout the transmission section, avoiding slack or breakage problems caused by the inclined path, and ensuring that the main body 3 of the coating machine can stably complete the coating process. In the embodiment: the arc-shaped plates 8 are symmetrically distributed on both sides of the top of the support plate 7, and the height of the arc-shaped plates 8 is lower than the height of the limiting plate 10, so as to avoid interfering with the movement of the limiting plate 10; Specifically, the arc-shaped plates 8 are symmetrically distributed on both sides of the top of the support plate 7, which can limit the left and right range of motion of the limiting plate 10, preventing the limiting plate 10 from deviating from its contact position due to the spring force of the spring 9 or the vibration of the take-up reel 6, and ensuring that the limiting plate 10 can always be in stable contact with the take-up reel 6; at the same time, the height of the arc-shaped plates 8 is lower than the height of the limiting plate 10, which can prevent the arc-shaped plates 8 from blocking the up and down movement of the limiting plate 10 under the action of the spring 9. For example, if the limiting plate 10 adjusts slightly up and down as the diameter of the take-up reel 6 changes during unwinding, it can ensure that the resistance adjustment function of the limiting plate 10 is not affected. Working principle: When the glass fiber coated film-wrapped electromagnetic wire is used in a precision positioning coating machine, the uncoated electromagnetic wire is first wound onto the take-up reel 16. Bolt 14 passes through the fixing frame 2 and the take-up reel 16, and the take-up reel 16 is locked in place with nut 15. After the electromagnetic wire is led out, it passes through the coating machine body 3 outside the fixing frame 2, and then winds around the outside of the take-up reel 2 17 fixed on the rotating shaft 16. The motor 12 fixed on the base plate 1 is started. The motor 12 drives the electromagnetic wire through the transmission structure formed by the output end locking plate 13, bolt 2 15 and nut 2 14. The rotating shaft 16 and the second winding reel 17 rotate to wind up the electromagnetic wire, while the main body 3 of the coating machine wraps the electromagnetic wire. The spring 9 on the outer support plate 7 of the base plate 1 applies elastic force to the limiting plate 10, so that the limiting plate 10 fits against the outer side of the first winding reel 6 to increase its rotational resistance and prevent the electromagnetic wire from loosening due to the first winding reel 6 rotating too fast. When the second winding reel 17 needs to be replaced, the bolt 2 15 and nut 2 14 are removed, and the rotating shaft 16 can be pulled out from the fixing frame 2 to complete the replacement. The axes of the first winding reel 6 and the second winding reel 17 are horizontal to ensure that the electromagnetic wire is taut to ensure the coating effect.
