Description

Technical Field

[0001] The present invention relates to the technical field of transformer winding equipment, in particular to a single-axis winding equipment for producing coils in transformer manufacturing. Background Art

[0002] A transformer is a common electrical structure. Its function, as the name suggests, is to change voltage. It primarily consists of a primary coil, a secondary coil, and an iron core (magnetic core). It is widely used in power systems, industrial production, transportation, communications, and other fields. There are many types of transformers, broadly classified as distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, and oil-immersed transformers. Transformers are conversion devices that use the principle of electromagnetic induction to change AC voltage. Transformers perform voltage, current, and impedance conversion functions, leading to their widespread use in the power industry. During transformer production and processing, the transformer's coils must be wound, requiring the use of appropriate winding machines.

[0003] The existing winding machine is unable to guide the wound coil evenly during the winding operation, thereby reducing the uniformity of the subsequent equipment in winding the workpiece, resulting in the wire not being able to be arranged neatly and tightly in the coil, affecting the product quality of the coil. At the same time, the equipment is also not convenient for quickly replacing the coil after unwinding. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: A single-axis winding device for transformer coil production includes a platform, a collection frame is fixedly connected to the top of the platform, the collection frame is located at the front end of the platform, a slide is opened on the top of the platform, and a slide rod is fixedly connected to the inside of the slide;

[0005] The rotating assembly is located inside the chute and is slidably connected to the platform through the chute;

[0006] A limit assembly is located at one end of the slide away from the rotating assembly, and the limit assembly is slidably connected to the platform through the slide;

[0007] The wire-paying assembly is fixedly installed on the top of the platform and is located at the rear end of the platform;

[0008] Among them, the wire-paying assembly includes a support plate, which is fixedly mounted on the top of the platform. The support plate is an L-shaped plate. A through hole is opened on the top of the support plate. The coil is installed on the wire-paying seat, so that the wire passes through the round hole on the slider, and then the wire passes through the inside of the fixed cylinder. At this time, the rollers on both sides limit the wire, which can ensure that the wire is arranged according to a predetermined path during the winding process, preventing the wire from crossing, overlapping or misaligned, so that the winding of the coil is more uniform and tight, and the quality and performance of the coil are improved. At the same time, when the tension of the wire is uneven during the wire-paying process, the roller can appropriately tighten or relax the wire through contact and friction with the wire, so that the tension of the wire is kept within an appropriate range, avoiding the influence of excessive or insufficient tension on the winding quality of the coil, and the rollers on both sides can quickly straighten the wire, thereby improving production efficiency. The inside of the through hole is slidably connected to the slider, and the bottom of the slider is fixedly connected to a guide member;

[0009] The guide member comprises a fixed cylinder, which is fixedly connected to the sliding block. Rollers are symmetrically arranged on the outer side of the fixed cylinder, and the rollers are rotatably connected to the fixed cylinder.

[0010] Preferably, a wire-releasing seat is fixedly connected to the top of the support plate near the through hole, a guide rod is fixedly connected to the inside of the through hole, the guide rod is slidably connected to the slider, a round hole is opened in the middle of the top of the slider, the round hole passes through the slider, and the round hole is connected to the inner cavity of the bottom fixed cylinder, and an electric push rod is fixedly connected to the side of the support plate near the collection frame. After the winding is completed, the electric push rod drives the fixed block to move toward the direction of the limit assembly, and the fixed block contacts the coil product outside the limit assembly, so that the coil product falls into the inside of the collection frame under the push of the fixed block, and the output end of the electric push rod is fixedly connected to the fixed block.

[0011] Preferably, there are multiple rollers, and the multiple rollers are divided into two groups. The rollers in one group are evenly distributed in the vertical direction of the fixed cylinder. The outer side of the roller is fixedly connected with a spring plate, and the wire passes through the fixed cylinder. The elastic performance of the spring plate is utilized to make the roller and the wire fit tightly. By setting the spring plate, the rollers on both sides can adapt to wires of various wire diameters and materials, thereby enhancing the versatility and flexibility of the winding machine. The spring plate is symmetrically arranged with the roller as the center, and the two sides of the spring plate are fixedly connected to the two symmetrical rollers. A groove is provided at the bottom of the fixed cylinder.

[0012] The cam is fixedly mounted on a support frame, and the cam is fixedly mounted on a support frame, and the cam is fixedly mounted on a support frame. The snap-fitting utilizes the elastic properties of the compression spring to ensure that the limit assembly and the rotating assembly always remain in close fit during operation, preventing shaking or displacement during the winding process, thereby ensuring the winding accuracy of the coil and making the position and spacing of each turn of the coil more uniform and consistent. The output end of the hydraulic cylinder passes through the fixed plate, and the output end of the hydraulic cylinder is rotatably connected to a connecting rod. A bearing is provided on the outside of the connecting rod, and the bearing is located at the interval between the connecting rod and the intermediate cylinder. The inside of the intermediate cylinder is slidably connected to a sliding block, and the outside of the sliding block is fixedly connected to a compression spring, and the end of the compression spring away from the sliding block is fixedly connected to the intermediate cylinder, and the side of the sliding block away from the compression spring is fixedly connected to a round rod, and the middle of the end of the round rod away from the sliding block is fixedly connected to the fixed rod. A limiting part is provided on the outside of the sliding block, and the limiting part is sleeved on the outside of the round rod.

[0013] When the slider moves left and right on the guide rod, the wire contacts the limit bar and is squeezed, and the return spring is compressed, and the limit bar drives the connecting cylinder to slide inside the middle cylinder. Under the mutual squeezing between the limit bar and the wire, the trapezoidal block moves in the direction away from the round rod, and the return spring and the elasticity are used to make the limit bar and the round rod clamped. The elastic properties of the elastic ring make the limit bar fit tightly against the outside of the wound wire, ensuring that the wire is arranged according to a predetermined path during the winding process, preventing the wire from being offset or misplaced, thereby ensuring the winding accuracy of the coil, making the position of each turn of the coil accurate, and the number of turns meeting the design requirements. It can also avoid unevenness or looseness, thereby ensuring the overall flatness and compactness of the coil, improving the quality and performance of the coil. At the same time, the limit bar fits tightly against the wire but maintains appropriate pressure, which can prevent the wire from rubbing or colliding with other components during the winding process, reducing wear and damage on the wire surface, and protecting the insulation layer and mechanical strength of the wire. The trapezoidal block is fixedly connected to the limit bar at one end away from the reset spring, and the limit bar passes through the fixed seat through the through slot. The outside of the limit bar is fixedly connected to an elastic ring. There are multiple limit bars, and the multiple limit bars are fixedly connected by the elastic ring.

[0014] Preferably, the rotating assembly includes a square plate, the square plate is located inside the slide groove, the square plate is slidably connected to the sliding rod, the outside of the square plate is fixedly connected to the motor, the output end of the motor passes through the square plate, the output end of the motor is fixedly connected to the rotating rod, the rotating rod is rotatably connected to the square plate, the outside of the rotating rod is rotatably connected to a guide plate, the guide plate is slidably connected to the sliding rod, the outside of the rotating rod is fixedly connected to an I-shaped ring, the I-shaped ring is located on the side of the guide plate away from the motor, the slider moves on the guide rod, so that the slider drives the fixed cylinder to move to the rotating assembly, so that the wire is located inside the slot outside the I-shaped ring, and then the motor drives the rotating rod to rotate, and the rotating rod drives the I-shaped ring to rotate. As the I-shaped ring rotates, the L-shaped rod is entangled with the wire, and the slider drives the wire to move along the slot and the square hole to the winding position, so that the wire contacts the outside of the round rod, and then the rotating rod rotates to start winding. After the winding is completed, the slider drives the wire back to the slot of the I-shaped ring. Inside, the wire between the I-ring and the trapezoidal ring is cut, and then the fixed plate and the connecting plate drive the wound coil to reset. At the same time, the hydraulic cylinder drives the round rod back to the inside of the intermediate tube for easy unloading. The end of the rotating rod is fixedly connected to the trapezoidal ring, and the outer side of the I-ring is provided with a slot. There are multiple slots, and the multiple slots are evenly distributed at the edge of the I-ring. The inner wall of the I-ring is fixedly connected to an L-shaped rod, and a square hole is provided on the outer side of the trapezoidal ring. The side of the trapezoidal ring away from the I-ring is fixedly connected to a limiting ring, and one side of the trapezoidal ring is fixedly connected to an inclined plate. The inclined plate is elastic and can buffer the wire during the winding process. When the wire generates impact due to various reasons, the inclined plate can absorb part of the impact force through its own elastic deformation to avoid excessive stretching or damage to the wire, which helps to protect the quality and integrity of the wire. The inclined plate is elastic, and a T-slot is provided in the middle of the end of the rotating rod.

At the same time, when the wire tension is uneven during the pay-off process, the roller can appropriately tighten or relax the wire through contact and friction with the wire, so that the wire tension is kept within the appropriate range, avoiding the impact of excessive or insufficient tension on the winding quality of the coil.

[0017] 2. The single-axis winding equipment used in the coil production of this transformer manufactures a round rod and a fixed rod that are clipped together with the rotating rod. By utilizing the elastic properties of the compression spring, the limit assembly and the rotating assembly can always maintain a close fit during operation, preventing shaking or displacement during the winding process, thereby ensuring the winding accuracy of the coil and making the position and spacing of each turn of the coil more uniform and consistent.

[0018] 3. The single-axis winding equipment used in the coil production of this transformer uses the elastic properties of the reset spring and the elastic ring to ensure that the limit bar fits tightly against the outside of the wound wire, ensuring that the wire is arranged according to the predetermined path during the winding process, preventing the wire from being offset or misaligned, thereby ensuring the winding accuracy of the coil.

After the winding is completed, the slider 53 drives the wire back to the inside of the slot 47 of the I-ring 45, and cuts the wire between the I-ring 45 and the trapezoidal ring 46. Then the fixed plate 31 and the connecting plate 32 drive the wound coil to reset, and at the same time the hydraulic cylinder 36 drives the round rod 37 back to the inside of the intermediate cylinder 34 to facilitate unloading.
