Description

Technical Field

[0001] This invention relates to the field of transformer winding equipment technology, specifically to a coil winding device for manufacturing aluminum transformers. Background Technology

[0002] A transformer is a common electrical structure whose function, as the name suggests, is to change voltage. A transformer mainly consists of a primary coil, a secondary coil, and an iron core (magnetic core). It is widely used in power systems, industrial production, transportation, and communications. There are many types of transformers, which can be broadly classified as distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, and oil-immersed transformers. A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. Transformers perform voltage transformation, current transformation, and impedance transformation, thus finding widespread application in the power industry. During the manufacturing process of a transformer, the coils need to be wound, requiring the use of appropriate winding machines.

[0003] Existing coil winding equipment used in aluminum transformer manufacturing suffers from several drawbacks. Firstly, the limited range of operating steps during coil mold installation on the equipment leads to low equipment efficiency. Secondly, the high vibration amplitude during coil winding affects winding efficiency and can easily damage the coil. Furthermore, fine impurities can easily enter the coil during winding, causing friction between the coils and resulting in scratches on the coil surface. Therefore, a new design has been developed to address these issues. Summary of the Invention

[0004] To address the aforementioned problems, the present invention provides the following technical solution: a coil winding device for manufacturing aluminum transformers, comprising a working platform for supporting the device. A winding frame is fixedly connected to both sides of the top of the working platform. A regulating mechanism is fixedly connected to one side of the outer surface of the winding frame. A first electric push rod is fixedly connected to the side of the winding frame closest to the regulating mechanism. The extension and retraction of the first electric push rod controls the movement of a docking mechanism. When the first electric push rod retracts away from the motor, it facilitates the placement of the coil mold onto the placement rod. A docking mechanism is fixedly connected to one end of the outer surface of the first electric push rod. The first electric push rod controls the docking mechanism to dock with the placement rod. The docking mechanism adapts to a limiting block, thereby fixing the coil mold and limiting the movement space of the components, thus facilitating subsequent winding operations. The interior of the winding frame is connected to... A receiving plate is fixedly connected to one side of the docking mechanism. A motor is fixedly connected to one side of the receiving plate. A connecting shaft is rotatably connected to the other side of the receiving plate. A limiting block is fixedly connected to the outside of the connecting shaft. The docking mechanism and the placement rod are plugged and unplugged by the first electric push rod. The docking mechanism and the limiting block form a closed connection, thereby forming a modular connection of the components, so as to realize the quick installation and disassembly of the components. A placement rod is fixedly connected to the side of the limiting block near the docking mechanism. The placement rod is used to load the coil mold. The coil mold is used to load the coil. The coil mold is set on the placement rod. A tension mechanism and a feeding mechanism are fixedly connected to the top of the winding frame away from the regulating mechanism. The coil enters from the side near the tension mechanism and is installed on the coil mold by the feeding mechanism. The connecting shaft is rotated to the side of the regulating mechanism by the motor, thereby achieving automatic winding operation. The tension mechanism includes a tension frame, with a third electric push rod fixedly connected to one side of the tension frame. When the coil passes in front of the tension frame, the third electric push rod controls the tension tool to adhere to the surface of the coil. The output end of the third electric push rod is fixedly connected to the tension tool. The third electric push rod drives the tension tool to continuously apply pressure to the surface of the line, thereby adjusting the tension of the line. At the same time, according to the equipment operation requirements, the pressure can be adaptively adjusted by extending and retracting the third electric push rod to meet the operation requirements of different tensions.

[0005] There are two tension mechanisms, which are correspondingly arranged on the winding frame and staggered. The two tension mechanisms work alternately to apply pressure, thereby improving the applicability and flexibility of the component.

[0006] The tensioning device includes a tension bracket, with a tension rod slidably connected to the center of the outer side of the tension bracket. A tension housing is fixedly connected to the outer end of the tension rod away from the third electric push rod. The tensioning device fits against the surface of the line. As the third electric push rod continuously applies pressure to maintain a certain tension on the line, a second spring is fitted on the outer side of the tension rod near the tension housing. Responding to the pressure applied by the line, the tension housing drives the tension rod to slide towards the tension bracket, causing the tension housing to compress and contract the second spring. This provides shock absorption and cushioning, reducing rigid collisions between the line and components, reducing wear, and providing some protection for the line. This extends the service life of the equipment, reduces the compressive force generated by the extension and retraction of the third electric push rod, and prevents line breakage during tension adjustment. The tension housing is located inside the tension housing away from the third electric push rod. A connecting shaft is fixedly connected to one side, and a roller block is rotatably connected to the outer side of the connecting shaft. The roller block contacts the surface of the wire and rotates appropriately during the wire tension adjustment process to reduce frictional damage to the wire and prevent surface damage. An annular groove is formed at the center of the outer side of the roller block. During tension adjustment, the wire is placed inside the annular groove, which limits the wire's vibration space, improves the stability of the wire during winding, and increases the efficiency of the equipment. A plastic block is fixedly connected to the inner wall of the annular groove. The plastic block is made of plastic to increase the friction between the component and the wire, prevent the wire from slipping on the component, maintain stable wire tension for continuous operation, reduce wear on the wire surface, reduce noise generated by friction between the component and the wire, and optimize the equipment's operating environment.

[0007] The docking mechanism includes a docking housing with a recessed groove on one side facing the connecting shaft. The docking housing connects with the placement rod through the recessed groove. The housing also has an internal recessed groove. When the placement rod is inserted into the recessed groove, it contacts the docking rod. A third spring is fixedly connected to the inner wall of the recessed groove. When the docking rod is subjected to compressive pressure, it compresses and contracts the third spring, thus providing shock absorption and buffering. This reduces the pressure generated during component docking, lowers noise or wear caused by component collisions, reduces docking pressure, improves the stability of the equipment during docking, and extends the service life of the equipment. The other end of the third spring is fixedly connected to the docking rod.

[0008] The regulating mechanism includes a regulating bracket. An auxiliary rod and a second electric push rod are fixedly connected to the outer side of the regulating bracket, corresponding to the coil mold. The second electric push rod controls the regulating tool to approach the surface of the coil mold. During the coil mold's winding and coiling process, the regulating tool compacts the coiled portion, thereby limiting the coil's winding area, preventing slippage, improving the neatness of the winding, preventing damage to the coil's surface, and avoiding affecting the coil's quality and performance. As the coil thickens, regulating tools are fixedly connected to the outer side of both the auxiliary rod and the second electric push rod. The second electric push rod adjusts its position according to the coil thickness, allowing for adaptive operation between components. The auxiliary rod extends and retracts with the second electric push rod, stabilizing the movement of the components.

[0009] The regulating tool includes a regulating frame and regulating blocks. When the regulating blocks contact the surface of the wire, as the wire winds around the coil mold, the wire compresses the regulating blocks, causing them to slide on the regulating slider. Fixed blocks are fixedly connected to opposite sides of the regulating frame, and a regulating slider is fixedly connected to one side of the fixed blocks. The regulating slider, according to its stroke, drives protrusions to compress and contract a first spring. Protrusions are fixedly connected to both sides of the regulating slider, and a first spring is sleeved on the outer side of each protrusion, allowing the spring to retain kinetic energy. The guide block provides support, causing it to adhere to the surface of the line. This restricts the winding of the line, prevents slippage, and improves the neatness of the winding. The guide block has a sliding groove on its outer side near the guide slider. The inner wall of the sliding groove is slidably connected to the outer side of the guide slider. During the winding process of the line on the coil mold, the guide block contracts when the line is squeezed in and rebounds when the line moves, thus adapting to the contraction of the guide block and maintaining the compaction of the coil by the component.

[0010] The feeding mechanism includes a feeding frame, with a sliding rod fixedly connected to the opposite side of the feeding frame. A feeding slider is slidably connected to the sliding rod. When the wire is wound around the coil mold, the feeding slider drives the feeding tube to slide on the sliding rod, allowing the coils to be neatly arranged layer by layer, thus satisfying the wire winding operation stroke. A feeding tube is fixedly connected to the inner side of the feeding slider. The wire enters the feeding tube from the friction tool side and moves from the feeding tube to the coil mold side via the guide tube. The feeding tube plays a role in planning and restricting the movement of the wire. A guide tube is fixedly connected to the outer side of the feeding tube near the coil mold. The guide tube has a structure that is wide at one end and narrow at the other end, with the narrower side near the coil mold. As the wire is wound, it moves closer to the narrower side of the guide tube, thus further constraining the vibration amplitude of the wire and improving the stability of the wire winding process. A connecting end is fixedly connected to the outer side of the feeding tube away from the guide tube, and a friction tool is plugged into the outer side of the connecting end.

[0011] The friction device includes a friction frame with several holes on its surface for insertion and removal between the frame and the connecting end, thus securing the component and preventing it from falling off during operation. A friction block is fixedly connected to the outside of the friction frame near the guide tube. When the wire enters the friction block, its surface rubs against the inner wall of the friction block, cleaning the wire and reducing impurities from entering the coil. This prevents the wires from rubbing against each other and avoids damage to the wires, thus protecting them. A soft rubber block is fixedly connected to the outside of the friction block, supporting it and acting as a shock absorber to reduce the amplitude of vibration between the wire and the friction block, improving the stability of the component.

[0012] This invention provides a coil winding device for manufacturing aluminum transformers. It has the following advantages: I. The coil winding equipment used in aluminum transformer manufacturing involves a third electric push rod controlling a tensioning device to adhere to the coil surface as the coil passes in front of the tension frame. The third electric push rod then drives the tensioning device to continuously apply pressure to the coil surface, thereby adjusting the coil tension. Simultaneously, the pressure can be adaptively adjusted by extending and retracting the third electric push rod according to the equipment's operational requirements, thus meeting the operational needs for different tensions.

[0013] II. In the coil winding equipment used for manufacturing aluminum transformers, the tensioning device is attached to the surface of the wire. As the third electric push rod continuously applies pressure to maintain a certain tension in the wire, the tension housing, driven by the pressure applied by the wire, slides towards the tension support. This causes the tension housing to compress and contract the second spring, thereby providing shock absorption and buffering, reducing rigid collisions between the wire and components, reducing wear between them, and providing a certain degree of protection for the wire. It also reduces the compressive force generated by the extension and retraction of the third electric push rod, preventing wire breakage during tension adjustment.

[0014] 3. The coil winding equipment used in aluminum transformer manufacturing has a roller block in contact with the wire surface. The roller block rotates appropriately during the wire tension adjustment process to reduce frictional damage to the wire. An annular groove is opened in the center of the roller block, and the wire is placed inside the annular groove. The annular groove limits the wire vibration space and improves the stability of the wire winding process. A plastic block is set inside the annular groove. The plastic block is made of plastic to increase the friction between the component and the wire, prevent the wire from slipping on the component, and maintain stable wire tension for continuous operation.

[0015] IV. The coil winding equipment used in the manufacture of aluminum transformers has a housing groove on the side of the housing facing the connecting shaft. The housing groove connects with the placement rod. When the placement rod is inserted into the housing groove, it contacts the docking rod. The docking rod is subjected to compressive pressure, which compresses and contracts the third spring, thereby playing a role in shock absorption and buffering. This reduces the pressure generated by the docking of components, reduces the noise or wear caused by component collisions, reduces docking pressure, improves the stability of the equipment during the docking process, and thus extends the service life of the equipment.

[0016] V. The coil winding equipment used in aluminum transformer manufacturing has the wire entering the feed tube from the friction tool side and moving from the feed tube to the coil mold side via the guide tube. The feed tube guides and restricts the movement of the wire. The guide tube has a structure that is wide at one end and narrow at the other, with the narrower side near the coil mold. As the wire is wound, it moves closer to the narrower side of the guide tube, which further constrains the vibration amplitude of the wire and improves the stability of the wire winding process. When the wire is wound on the coil mold, the feed slider drives the feed tube to slide on the slide rod, so that the coil is neatly arranged layer by layer, thereby meeting the wire winding operation stroke.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] First embodiment, such as Figures 1 to 3As shown, the present invention provides a technical solution: a coil winding device for manufacturing aluminum transformers, comprising a working platform 1, a winding frame 2 fixedly connected to both sides of the top of the working platform 1, a regulating mechanism 3 fixedly connected to one side of the outside of the winding frame 2, a first electric push rod 13 fixedly connected to the side of the winding frame 2 near the regulating mechanism 3, a docking mechanism 6 fixedly connected to one end of the outside of the first electric push rod 13, a receiving plate 8 fixedly connected to the side of the inside of the winding frame 2 corresponding to the docking mechanism 6, a motor 7 fixedly connected to one side of the outside of the receiving plate 8, a connecting shaft 9 rotatably connected to the other side of the receiving plate 8, a limiting block 10 fixedly connected to the outside of the connecting shaft 9, a placement rod 11 fixedly connected to the side of the limiting block 10 near the docking mechanism 6, a coil mold 12 set on the placement rod 11, and a tension mechanism 5 and a feeding mechanism 4 fixedly connected to the top of the winding frame 2 away from the regulating mechanism 3, respectively. There are two tension mechanisms 5, which are correspondingly arranged on the winding frame 2 and staggered. The working platform 1 is used to support the equipment. The placement rod 11 is used to load the coil mold 12. The coil mold 12 is used to load the coil. The docking mechanism 6 is moved by the extension and retraction control of the first electric push rod 13. When the first electric push rod 13 retracts away from the motor 7, it is easy to put the coil mold 12 on the placement rod 11. The first electric push rod 13 controls the docking mechanism 6 to dock with the placement rod 11. The docking mechanism 6 and the limiting block 10 are adapted to fix the coil mold 12 and limit the movement space of the component, so as to facilitate the subsequent winding operation. The docking mechanism 6 and the placement rod 11 are plugged and unplugged by the first electric push rod 13. The docking mechanism 6 and the limiting block 10 form a closed connection, thus forming a modular connection of the component, thereby realizing the quick installation and disassembly of the component. The coil enters from the side close to the tension mechanism 5 and is installed on the coil mold 12 by the feeding mechanism 4. The connecting shaft 9 is rotated towards the regulating mechanism 3 by the motor 7, thereby realizing the automatic winding operation.

[0021] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 4 to 10 As shown, the tension mechanism 5 includes a tension frame 51. A third electric push rod 52 is fixedly connected to one side of the tension frame 51, and a tensioning device 53 is fixedly connected to the output end of the third electric push rod 52. When the coil passes in front of the tension frame 51, the tensioning device 53 is controlled by the third electric push rod 52 to adhere to the surface of the coil. Then, the third electric push rod 52 drives the tensioning device 53 to continuously apply pressure to the surface of the coil, thereby adjusting the tension of the coil. At the same time, according to the operational requirements of the equipment, the pressure is adaptively adjusted by extending and retracting the third electric push rod 52 to meet the operational requirements of different tensions.

[0022] The tension device 53 includes a tension bracket 531. A tension support rod 532 is slidably connected to the center of the outer side of the tension bracket 531. A tension housing 533 is fixedly connected to the outer end of the tension support rod 532 away from the third electric push rod 52. A second spring 534 is sleeved on the outer side of the tension support rod 532 near the tension housing 533. A connecting shaft 535 is fixedly connected to the inner side of the tension housing 533 away from the third electric push rod 52. A roller block 536 is rotatably connected to the outer side of the connecting shaft 535. An annular groove 537 is formed at the center of the outer side of the roller block 536. A plastic block 538 is fixedly connected to the inner wall of the annular groove 537. Tensioner 53 is attached to the surface of the line. As the third electric push rod 52 continuously applies pressure, maintaining a certain tension on the line, the tension housing 533, driven by the pressure, slides the tension support rod 532 towards the tension bracket 531. This causes the tension housing 533 to compress and contract the second spring 534, thus providing shock absorption and buffering, reducing rigid collisions between the line and components, reducing wear, and providing some protection for the line. This extends the service life of the equipment, reduces the compressive force generated by the extension and retraction of the third electric push rod 52, and prevents line breakage during tension adjustment. The roller block 536 contacts the surface of the line, and the roller block 536... During the tension adjustment process, appropriate rotation is performed to reduce frictional damage to the wire and prevent surface damage. A centrally located annular groove 537 is provided on the roller block 536. During tension adjustment, the wire is placed inside the annular groove 537, which limits the wire's vibration space, improving stability during winding and increasing equipment efficiency. A plastic block 538, made of plastic, is installed inside the annular groove 537 to increase friction between the component and the wire, preventing slippage and maintaining stable tension for continuous operation. This also reduces wear on the wire surface, lowers noise generated by friction between the component and the wire, and optimizes the equipment's operating environment.

[0023] In use, the work platform 1 is used to support the equipment, the placement rod 11 is used to load the coil mold 12, and the coil mold 12 is used to load the coil. The first electric push rod 13 extends and retracts to control the movement of the docking mechanism 6. When the first electric push rod 13 retracts away from the side of the motor 7, it is convenient to put the coil mold 12 onto the placement rod 11. The first electric push rod 13 controls the docking mechanism 6 to dock with the side of the placement rod 11. The docking mechanism 6 and the limiting block 10 perform an adaptation operation to fix the coil mold 12 and limit the movement space of the components, thereby facilitating the subsequent winding operation. The docking mechanism 6 is controlled by the first electric push rod 13 to insert and plug into the placement rod 11. The docking mechanism 6 and the limiting block 10 form a closed connection, thereby forming a modular connection of the components, so as to realize the rapid installation and disassembly of the components. The coil enters from the side closest to the tension mechanism 5 and is installed on the coil mold 12 via the feeding mechanism 4. The tension mechanism 5 adjusts the tension of the wire according to the operation requirements to maintain the tension of the wire and ensure normal operation of the equipment. Then, the wire enters the feeding mechanism 4 and the feeding mechanism 4 restricts the movement space of the wire to perform pre-operation for subsequent winding and coiling. At the same time, the feeding mechanism 4 performs appropriate friction cleaning on the surface of the wire to reduce the adsorption of impurities and prevent impurities from entering during the winding process, thus preventing them from affecting the quality of the coil. The motor 7 controls the connecting shaft 9 to rotate towards the regulating mechanism 3, thereby achieving automatic winding operation.

[0024] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
