Description

Technical Field

[0001] This invention relates to the field of coil winding technology, and more specifically to a high-efficiency and stable coil winding device. Background Technology

[0002] Current technology for coil winding typically involves manual processing. However, the quality of manual processing is greatly affected by the operator's condition, making it difficult to guarantee product precision and consistency. Furthermore, manual processing is inefficient and cannot meet the demands of mass production. Additionally, manual winding is prone to issues such as wire springback and incomplete bending, and the inability to effectively heat the workpiece during the process results in poor coil forming and inadequate shaping. Most existing semi-automatic winding devices can only complete a single pressing and forming process, and deformation and springback are common after forming, requiring secondary manual adjustments. This approach fails to improve processing efficiency and cannot guarantee the quality of the finished product.

[0003] A Chinese invention patent with publication number CN102426913A discloses a coil winding device and a segmented winding method, including a machine base, a control device mounted on the machine base, a winding bar located at the center of the machine base, and a stroke-adjustable cylinder mounted on the machine base. The stroke-adjustable cylinder is connected to a winding module, which is equipped with a temperature probe and a heating device. A feeding module is slidably mounted on the machine base. The stroke-adjustable cylinder, temperature probe, and heating device are connected to the control device. Multiple winding modules are configured, each connected to a corresponding stroke-adjustable cylinder. These multiple stroke-adjustable cylinders are evenly mounted on the machine base around the winding bar. The winding module has an arc-shaped extrusion port.

[0004] However, when the second and third coil modules are pressed on the wire, the coil may bend during the pressing process, resulting in deformation and failure to form a complete circle. As a result, the final molding quality is still unstable. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a highly efficient and stable coil winding device, including a base and control components and a core rod mounted on the base. Two sets of pressing components a and two sets of pressing components b are arranged circumferentially around the core rod on the base. A pushing component is provided on one side of pressing component b. Pressing component a includes symmetrically arranged clamps a and b, and pressing component b includes symmetrically arranged carrier members a and b. Clamps c and d are slidably mounted on the front ends of carrier members a and b, respectively. This invention solves the problems of easy coil deformation and inability to ensure secure coil shaping in existing technologies.

[0006] The technical solution of the present invention is as follows:

[0007] A high-efficiency and stable coil winding device includes a base and a control component and a core rod disposed on the base. Two sets of pressing components a and two sets of pressing components b are arranged circumferentially around the core rod on the base. A pushing component is disposed on one side of each pressing component b. Each pressing component a includes symmetrically arranged clamps a and b, and each pressing component b includes symmetrically arranged carrier members a and b. Clamps c and d are slidably disposed at the front ends of carrier members a and b, respectively. Clamps a, c, d, and b sequentially press the coil and then move synchronously to press the coil multiple times. During the forward movement of clamps c and d, the pushing component pushes them, causing clamps c and d to deflect around the core rod, thus bending the conductor.

[0008] As a preferred embodiment, the pressing assembly a further includes a sliding seat a and a sliding seat b fixedly mounted on the base. A clamping cylinder a and a slider a driven by the clamping cylinder a are fixedly mounted on the sliding seat a. A clamping cylinder b and a slider b driven by the clamping cylinder b are fixedly mounted on the sliding seat b. The slider a and slider b are threadedly connected to clamp a and clamp b respectively. Two fixing rods are threadedly connected to the front end of clamp b. An insertion hole a and an insertion hole b are provided on clamp a, clamp b, clamp c and clamp d respectively.

[0009] As a preferred embodiment, the front end of the carrier a is provided with a receiving groove a for installing the clamp c, and the upper and lower ends of the inner wall of the receiving groove a are provided with sliding grooves a, and the end of the clamp c is fixedly connected to the sliding groove a. The front end of the carrier b is provided with a receiving groove b for installing the clamp d, and the upper and lower ends of the inner wall of the receiving groove b are provided with sliding grooves b, and the end of the clamp d is fixedly connected to the sliding groove b.

[0010] As a preferred embodiment, the pressing assembly b further includes a sliding seat c and a sliding seat d fixedly mounted on the base. A clamping cylinder c and a slider c driven by the clamping cylinder c are fixedly mounted on the sliding seat c. A clamping cylinder d and a slider d driven by the clamping cylinder d are fixedly mounted on the sliding seat d. The slider c and slider d are threadedly connected to the clamping c and clamping d, respectively.

[0011] As a preferred embodiment, the push assembly includes a support rod fixedly disposed on the left side of the sliding seat c and the right side of the sliding seat d. A cylinder is fixedly connected to the top of the support rod, and a push rod is slidably disposed inside the cylinder. A spring is fixedly connected to the tail end of the push rod.

[0012] As a preferred embodiment, a feeding component is provided on one side of the pressing component a. The feeding component includes a support base fixedly mounted on the machine base and a feeding cylinder a fixedly mounted on the support base. A slide rail a is fixedly mounted on the support base, and a connecting arm driven by the feeding cylinder a is slidably mounted on the slide rail a.

[0013] As a preferred embodiment, one end of the connecting arm is fixedly connected to a gripper a and a feeding cylinder b, and another end of the connecting arm is also provided with a slide rail b, on which the gripper b is slidably mounted under the action of the feeding cylinder b.

[0014] As a preferred embodiment, a loading platform is fixedly provided below the connecting arm, and a limit groove is provided on the loading platform.

[0015] As a preferred embodiment, the control components include a PLC control panel fixedly mounted on the top of the base, a control switch, and an electrical cabinet fixedly mounted on the bottom of the base.

[0016] As another preferred embodiment, both pressing component a and pressing component b are provided with heating modules, the heating modules including a heating rod inserted into insertion hole a and a temperature controller inserted into insertion hole b.

[0017] The beneficial effects of this invention are as follows:

[0018] 1. In this invention, clamps c and d in the pressing assembly b are slidably disposed at the front ends of the carrier a and carrier b, respectively. After clamp a presses the wire onto the core rod, clamps c and d move forward in sequence to press the wire. During the forward movement of clamps c and d, they come into contact with the push rod in the push assembly, causing the push rod to push clamps c and d to move slightly around the core rod, thereby giving the wire a smoothing motion to one side. This allows the wire to fit more closely to the core rod, while preventing the wire from bending and deforming, which would prevent it from being rolled into a complete circle and effectively shaped, thus affecting the processing quality of the product. This ensures that the roundness of the coil after molding meets the requirements, reduces the workload of subsequent finishing, and greatly improves processing efficiency and finished product quality.

[0019] 2. This invention uses four clamps to press the coil sequentially while simultaneously heating it during the rolling process. This effectively prevents the coil from springing back and deforming after processing, ensuring the stability of the finished product's shape. No manual secondary adjustments are required. Furthermore, after the four clamps press the coil sequentially, they can press it multiple times synchronously again, ensuring the coil's firmness in shaping.

[0020] 3. In existing rolling equipment, during the rolling operation, one end of the wire is usually placed in front of the first clamp during feeding. After the first clamp presses and positions the wire, subsequent clamps press the wire in a clockwise or counterclockwise direction. However, after the first clamp presses 1 / 4 of the wire, the remaining 3 / 4 of the wire is longer and has a larger angle. This easily leads to incorrect bending and deformation of the wire when the second and third clamps press it, making it impossible for the wire to naturally adhere to the side wall of the mandrel, resulting in an irregular shape after final forming. In contrast, this device uses a push rod in conjunction with the elastic thrust of a spring to apply a certain pre-tightening thrust to the wire during the pressing process of clamps c and d, and to push the wire to one side, keeping the wire in contact with the mandrel at all times, preventing bending and deviation of the wire, and ensuring a stable and reliable rolling process.

[0021] 4. This invention includes a feeding assembly. After the operator places the stacked wires into the limiting groove on the loading platform, the feeding cylinder b drives the lower gripper b to move in conjunction with the gripper a to clamp the wires. Then, driven by the feeding cylinder a, the wires are transported to the core rod position to complete the loading. This not only eliminates the need for manual loading, reducing the labor intensity of the operators, but also enables more precise loading, ensuring that the wires are placed in the preset position, effectively improving the processing efficiency and quality during production.

Detailed Implementation

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] Example 1

[0039] like Figures 1 to 14As shown, a high-efficiency and stable coil winding device includes a base 1 and a control component 2 and a core rod 3 disposed on the base 1. Two sets of pressing components a4 and two sets of pressing components b5 are arranged circumferentially around the core rod 3 on the base 1. A pushing component 7 is disposed on one side of the pressing component b5. The pressing component a4 includes symmetrically arranged clamps a41 and b42. The pressing component b5 includes symmetrically arranged carriers a51 and b52. Clamps c53 and d54 are slidably disposed at the front ends of carriers a51 and b52, respectively. Clamps a41, c53, d54 and b42 press the coil sequentially and then move synchronously to press the coil multiple times. During the forward movement of clamps c53 and d54, the pushing component 7 pushes them, causing clamps c53 and d54 to deflect around the core rod 3 and bend the wire. After clamp a41 presses the wire onto the core rod 3, clamps c53 and d54 move forward sequentially to press the wire. During the forward movement of clamps c53 and d54, they come into contact with the push rod 73 in the push assembly 7. This push rod 73 pushes clamps c53 and d54 to make a small movement around the core rod 3, thus smoothing the wire to one side. This allows the wire to fit more closely to the core rod, ensuring that the roundness of the formed coil meets the requirements, greatly improving processing efficiency and product quality. Furthermore, during the pressing process, the heating module 8... The heating rod 81 heats the four clamps. During the pressing process, the four clamps roll and shape the wire while it is heated, effectively preventing the coil from springing back and deforming after processing. After the four clamps press in sequence, they can press the coil multiple times simultaneously to further ensure the firmness of the coil shape and the stability of the finished product shape. The front ends of clamps a41, b42, c53 and d54 are all provided with arc-shaped grooves that match the outer ring of the core rod 3, ensuring that the wire can be effectively and tightly attached to the outer ring of the core rod 3.

[0040] like Figure 4 , Figure 5 , Figure 7 and Figure 13As shown, the pressing assembly a4 also includes a sliding seat a43 and a sliding seat b44 fixedly mounted on the base 1. A clamping cylinder a45 and a slider a46 driven by the clamping cylinder a45 are fixedly mounted on the sliding seat a43. A clamping cylinder b47 and a slider b48 driven by the clamping cylinder b47 are fixedly mounted on the sliding seat b44. The slider a46 and the slider b48 are threadedly connected to the clamps a41 and b42 respectively. The clamps a41, b42, c53 and d54 are all provided with mounting holes a410 and b411. Clamp a41 is threadedly connected to slider a46, and the tail end of slider a46 is fixedly connected to the front end of the piston rod of clamp cylinder a45. Clamp cylinder a45 can drive slider a46 and clamp a41 to move back and forth along sliding seat a43. Similarly, clamp b42 is threadedly connected to slider b48, and the tail end of slider b48 is fixedly connected to the front end of the piston rod of clamp cylinder b47. Clamp cylinder b47 can drive slider b48 and clamp b42 to move back and forth along sliding seat b44; [Installation hole] A410 is used to insert the heating rod 81, which heats clamps A41, B42, C53, and D54. Clamps A41, B42, C53, and D54 are made of metal, which provides good thermal conductivity, thus heating and shaping the wires. The insertion hole B411 is used to insert the temperature controller 82, which monitors the temperature and allows staff to adjust the temperature in a timely manner to avoid the temperature being below standard or exceeding the set value.

[0041] like Figure 8 , Figure 10 and Figure 12As shown, the front end of the carrier a51 has a receiving groove a55 for installing the clamp c53. The upper and lower ends of the inner wall of the receiving groove a55 have sliding grooves a513. The end of the clamp c53 is fixedly connected to the sliding groove a513 with a limiting member a514. The front end of the carrier b52 has a receiving groove b56 for installing the clamp d54. The upper and lower ends of the inner wall of the receiving groove b56 have sliding grooves b515. The end of the clamp d54 is fixedly connected to the sliding groove b515 with a limiting member b516. The clamp c53 is slidably disposed inside the receiving groove a55. The shape and size of the receiving groove a55 match the clamp c53. The height of the receiving groove a55 is the same as the height of the clamp c53, while the width is slightly larger than the width of the clamp c53. This allows the clamp c53 to move within a certain range without disengaging. After the clamp c53 contacts the push rod 73 and the clamp b42, it can slide within the receiving groove a55. The limiting member a514 at the end of the clamp c53 is embedded in the sliding groove. Inside a513, the shape and size of the limiting member a514 match the slide groove a513. Through the cooperation of the limiting member a514 and the slide groove a513, not only can the clamp c53 be limited, preventing it from disengaging during sliding, but the slide groove a513 is also centered on the mandrel 3. Therefore, it ensures that the clamp c53 moves around the mandrel 3 during sliding, smoothly pressing the wire to one side so that it can better fit against the outer ring of the mandrel 3; similarly... The clamp d54 is slidably disposed inside the receiving groove b56. The shape and size of the receiving groove b56 match the clamp d54. The height of the receiving groove b56 is the same as the height of the clamp d54, while the width is slightly larger than the width of the clamp d54, allowing the clamp d54 to move within a certain range without disengaging. This allows the clamp d54 to slide within the receiving groove a55 after contacting the push rod 73 and the clamp b42. The limiting member b516 at the end of the clamp d54 is embedded in... Inside the slide groove b515, the shape and size of the limiting member b516 match the slide groove b515. Through the cooperation of the limiting member b516 and the slide groove b515, not only can the clamp d54 be limited to prevent it from disengaging during sliding, but the slide groove b515 is opened with the core rod 3 as the center. Therefore, it can ensure that the clamp d54 moves with the core rod 3 as the center during sliding, and can smoothly press the wire to one side so that it can better fit with the outer ring of the core rod 3.

[0042] like Figure 4As shown, the pressing assembly b5 also includes a sliding seat c57 and a sliding seat d58 fixedly mounted on the base 1. A clamping cylinder c59 and a slider c510 driven by the clamping cylinder c59 are fixedly mounted on the sliding seat c57. A clamping cylinder d511 and a slider d512 driven by the clamping cylinder d511 are fixedly mounted on the sliding seat d58. The slider c510 and the slider d512 are threadedly connected to the carrier a51 and the carrier b52, respectively. The carrier a51 is threadedly connected to the slider c510. The tail end of the slider c510 is fixedly connected to the front end of the piston rod of the clamp cylinder c59. The clamp cylinder c59 can drive the slider c510, the carrier a51, and the clamp c53 to move back and forth along the sliding seat c57. Similarly, the carrier b52 is threadedly connected to the slider d512. The tail end of the slider d512 is fixedly connected to the front end of the piston rod of the clamp cylinder d511. The clamp cylinder d511 can drive the slider d512, the carrier b52, and the clamp d54 to move back and forth along the sliding seat d58.

[0043] like Figure 5 , Figure 10 and Figure 12As shown, the push assembly 7 includes a support rod 71 fixedly mounted on the left side of the sliding seat c57 and the right side of the sliding seat d58. A cylinder 72 is fixedly connected to the top of the support rod 71, and a push rod 73 is slidably mounted inside the cylinder 72. A spring 74 is fixedly connected to the tail end of the push rod 73. The two cylinders 72 are located on the outer sides of the sliding seats c57 and d58, respectively. The push rod 73 is perpendicular to the angle between the support member a51 and the support member b52. When the clamp cylinder c59 pushes the support member a51, carrying the clamp c53, to move towards the mandrel 3, the outer side of the clamp c53 gradually contacts the front end of the push rod 73. As the support member a51 continues to move forward, the push rod 73 is pushed into the cylinder 72 to slide and compress the spring 74. The spring 74 is compressed and generates a reverse elastic thrust, and the elastic force of the spring 74 is greater than the pushing force of the clamp c53 on the push rod 73. When the outer side of clamp c53 contacts the push rod 73, it receives an elastic thrust in the counterclockwise direction towards the mandrel 3. This push rod 73 then propels clamp c53 to move slightly within the receiving groove a55 in the counterclockwise direction along the mandrel 3. The same process occurs during the movement and pressing of clamp d54. The push rod 73 applies the same preload thrust to clamp d54. When clamp cylinder d511 pushes the carrier b52, moving clamp d54 towards the mandrel 3, the outer side of clamp d54 contacts the push rod 73, receiving an elastic thrust in the clockwise direction towards the mandrel 3. The push rod 73 pushes the clamp d54 to move slightly clockwise along the core rod 3 within the receiving groove b56, allowing both clamps to smooth and push the wire during the pressing process. After clamps c53 and d54 finish pressing the wire, their positions remain unchanged, and the elastic force continues to act on the wire through clamps c53 and d54, producing a smoothing and pre-tightening effect to ensure the wire adheres to the side wall of the core rod. After clamps c53 and d54 finish pressing, clamp b42 moves towards the core rod 3 under the push of clamp cylinder b47. When the clamps c53, d54 and b42 are in contact, the angle between them is smaller than the angle between them and a41. Therefore, clamp b42 will abut against clamps c53 and d54. After clamp b42 contacts clamps c53 and d54, it pushes clamps c53 and d54 to move in the opposite direction to overcome the thrust of push rod 73 and complete the reset. This makes the wire fit tightly against the outer ring of core rod 3. The arc grooves opened at the front end of clamps c53 and d54 are smooth, so they will not cause wear or interference to the wire during reset.

[0044] like Figure 2 and Figure 3As shown, a feeding component 6 is provided on one side of the pressing component a4. The feeding component 6 includes a support base 61 fixedly mounted on the machine base 1 and a feeding cylinder a62 fixedly mounted on the support base 61. A slide rail a63 is fixedly mounted on the support base 61, and a connecting arm 64 driven by the feeding cylinder a62 is slidably mounted on the slide rail a63. After the operator places the stacked wires into the limiting groove 610 on the loading table 69, the feeding cylinder b62 drives the lower gripper b68 to move and cooperate with the gripper a65 to clamp the wires. Then, driven by the feeding cylinder a62, the wires are transported to the core rod 3 position to complete the loading. This not only eliminates the need for manual loading, reducing the labor intensity of the operators, but also enables more precise loading, ensuring that the wires are placed in the preset position, effectively improving the processing efficiency and quality during production.

[0045] like Figure 3 As shown, a gripper a65 and a feeding cylinder b66 are fixedly connected to one end of the connecting arm 64. A slide rail b67 is also provided at one end of the connecting arm 64, and a gripper b68, driven by the feeding cylinder b66, is slidably mounted on the slide rail b67. The bottom surfaces of grippers a65 and b68 are higher than the top surface of the core rod 3, so that when grippers a65 and b68 move the wire to the core rod 3, they will not interfere with the core rod 3. The inner sides of grippers a65 and b68 that are in contact with the wire can be provided with buffer strips made of flexible materials such as silicone to avoid damage to the wire during gripping and to enhance friction to ensure stability during the gripping process. After the wire is loaded, the middle part of the wire is tangent to the core rod 3, so that the wire is bent into a "U" shape after the clamp a41 presses the wire. When the clamps c53 and d54 press the two sides of the "U" shape of the wire and push them together, the wire can fit the core rod more closely. Then, when the clamp b42 presses the wire, the entire wire can fit completely into the outer ring of the core rod 3, ensuring that the final coil has a regular roundness.

[0046] like Figure 3 As shown, a loading platform 69 is fixedly installed below the connecting arm 64, and a limiting groove 610 is provided on the loading platform 69. The size of the limiting groove 610 matches the width of the wire, and the limiting groove 610 is located directly below the gripper a65.

[0047] like Figure 1As shown, the control assembly 2 includes a PLC control panel 21 fixedly mounted on the top of the base 1, a control switch 22, and an electrical cabinet 23 fixedly mounted on the bottom of the base 1. The PLC control panel 21 is electrically connected to clamp cylinders a45, b47, c59, and d511, feeding cylinders a62 and b66, heating rod 81, and temperature controller 82. Operators can preset the action sequence and duration of each cylinder, as well as the heating temperature of the heating rod 81, through the PLC control panel 21. The electrical cabinet 23 contains an air pump that provides power to clamp cylinders a45, b47, c59, d511, a feeding cylinder a62, and a heating rod 81. The power supply module ensures the stable and orderly operation of all components of the device. Operators can quickly start or stop the device via control switch 22, making operation convenient. The entire device can automatically complete the entire process of feeding, rolling, and shaping according to a preset program. After each processing cycle, all components automatically reset, ready for the next coil processing cycle. The processing efficiency is high, and manual labor is only required to place the wires and pick up the finished products. The high degree of automation reduces labor costs and eliminates the influence of the operator's state on product quality during manual processing. Product precision and consistency are guaranteed, and production efficiency is greatly improved.

[0048] like Figure 7 As shown, both pressing components a4 and b5 are equipped with heating modules 8. The heating module 8 includes a heating rod 81 inserted into the insertion hole a410 and a temperature controller 82 inserted into the insertion hole b411. The heating temperature range is set between 140°C and 180°C, with 150°C being the optimal heating temperature. This temperature range ensures the insulation layer of the insulated wire softens and sets without causing overheating, aging, or damage, thus ensuring the insulation performance of the coil remains unaffected after processing. The temperature controller 82 feeds back the temperature data to the PLC control panel 21 in real time. When the temperature is below the set range, the PLC control panel 21 automatically controls the heating rod 81 to increase its heating power; when the temperature is above the set range, it automatically reduces the power, ensuring the heating temperature remains stable within the set range and improving the stability of the setting effect.

[0049] Example 2

[0050] like Figure 7 and Figure 14As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to with the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 will be described below. The difference between Embodiment 2 and Embodiment 1 is that the front end of clamp b42 is threaded with two fixing rods 49. The fixing rods 49 make clamp b42 more stable when pushing clamp c53 and clamp d54. The length of the fixing rods 49 is set to be slightly longer than the protruding length of the arc groove of clamp b42. When clamp b42 moves towards the mandrel 3, the fixing rods 49 will contact clamp c53 and clamp d54 first, pushing them to complete the reset. This will not interfere with the final pressing action of clamp b42 on the wire. At the same time, the positions of the two fixing rods 49 correspond to the outer sides of clamp c53 and clamp d54 respectively, so the force is evenly distributed and the pushing and resetting process is more stable and smooth.

[0051] Working principle: First, the operator places the stacked wires into the limiting groove 610 of the loading platform 69. Then, the device is started by controlling switch 22. Then, the feeding cylinder b62 drives the gripper b68 to move towards the gripper a65 to grip the wire. Next, the feeding cylinder a62 drives the connecting arm 64, gripper a65 and gripper b68 to move towards the core rod 3 so that the middle position of the wire is tangent to the outer side of the core rod 3, completing the loading at the preset position. Then, the clamping cylinder a drives 45 to move the clamp a41 forward to press the middle of the wire against the outer ring of the core rod 3, completing the first pressing and positioning. Then, the clamp c53 moves forward under the action of the clamping cylinder c59 to perform the second pressing of the wire. During the pressing process, the push rod 73 applies an elastic force to the clamp c53 under the action of the spring 74, pushing the clamp c53 to move slightly counterclockwise along the core rod 3 to pre-tighten and straighten the wire. Push, then clamp d54 moves forward under the drive of clamp cylinder d511 to perform the third pressing. Through the push rod 73, an elastic push force is obtained in the clockwise direction of the core rod 3, pushing clamp d54 to move slightly to pre-tighten and push the wire. Then clamp cylinder b47 drives clamp b42 to move forward to perform the fourth pressing. During the pressing process, clamp b42 abuts against clamp c53 and clamp d54, pushing the two clamps to overcome the push force of push rod 73 and reset in the opposite direction, so that the four clamps together press the wire tightly against the outer wall of the core rod 3. After the sequential pressing is completed, the four clamps move back and forth synchronously to press and shape the coil multiple times. At the same time, the heating rod 81 of heating module 8 continuously heats the four clamps, so that the wire is shaped under the heated pressing state. After the worker removes the coil that has been rolled, the next wire to be processed is placed in the limiting groove 610. The processing process is repeated in sequence.
