Description

Technical Field

[0001] This invention belongs to the field of transformer manufacturing technology, specifically relating to a winding device and method for transformer manufacturing. Background Technology

[0002] A transformer is a key electrical device that uses the principle of electromagnetic induction to achieve voltage transformation and power transmission. It mainly consists of an iron core and windings. The quality of the windings directly affects the operational stability, insulation life, and heat dissipation performance of the equipment. The winding process is the core processing step of uniformly and tightly winding insulated wires onto the iron core or frame. Traditional processes are prone to problems such as loose wire arrangement, insufficient compaction in some areas, and uneven tension when winding irregularly shaped iron cores such as ellipses. In particular, gaps or insulation damage are easily generated at curved transition areas, making it difficult to ensure the winding density and winding accuracy, thus affecting the overall performance of the transformer.

[0003] Patent application CN113327765B discloses an elliptical transformer coil manufacturing device. It utilizes the principle of a cylindrical cam structure to cause the guide block to move a certain distance after the iron core rotates once, thereby ensuring that the wires are evenly distributed on the iron core.

[0004] The aforementioned patent relies on mechanical chutes to achieve intermittent feeding, with a fixed motion trajectory and limited adjustment range. When winding elliptical iron cores, it is prone to uneven wire laying and insufficient local compaction. Furthermore, the clamping structure relies solely on springs and rubber blocks for simple fixation, making it difficult to adapt to iron cores of different sizes. In addition, the lack of real-time control over the wire clamping force can easily cause wire loosening or insulation damage. During later use, it is prone to vibration displacement, insulation wear, and safety hazards such as overheating and short circuits.

[0005] In response, we propose a winding device and method for transformer manufacturing to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a winding device and method for transformer manufacturing, in order to solve the following problems existing in the prior art: 1. Uneven compaction of elliptical iron core conductors; 2. The compaction pressure of the winding device is uncontrollable; 3. Lateral compaction results in insufficient winding density.

[0007] The objective of this invention can be achieved through the following technical solutions: A winding device for transformer production includes a mounting plate, a motor mounted on one side wall of the mounting plate, the output end of the motor passing through the mounting plate and connected to a mounting shaft for placing an iron core, and a pair of fixed shafts corresponding to the positions of the mounting shafts mounted on one side wall of the mounting plate, with a side pressure assembly mounted on the fixed shafts. The side pressure assembly includes a base plate, with a pair of sliding sleeves slidably connected to a fixed shaft at the upper end of the base plate, and a spring telescopic rod fixedly connected to the lower end of the base plate. A side pressure ring is rotatably connected to the lower end of the spring telescopic rod, and the side pressure ring abuts against the side wall of the conductor and presses it firmly.

[0008] Preferably, a second motor is mounted on the side wall of the mounting plate away from the motor, and a lead screw is connected to the output end of the second motor. A column is provided at the upper end of the base plate, and a threaded hole adapted to the lead screw is opened at the upper end of the column. The lead screw and the threaded hole are threadedly connected.

[0009] Preferably, a pressure sensor is installed inside the side pressure ring. The electrical signal of the pressure sensor is transmitted to the second motor through an external processor. The second motor controls the side pressure assembly to move gradually and maintain a constant pressure between the side pressure ring and the wire.

[0010] Preferably, the upper end of mounting plate one is connected to mounting plate two via a connecting plate, the end of screw one is rotatably connected to mounting plate two, and the fixed shaft is fixedly connected to mounting plate two.

[0011] Preferably, a hammer pressing assembly is symmetrically installed on the upper end of the base plate. The hammer pressing assembly includes a motor four fixedly installed on the upper end of the base plate. A lead screw two is installed on the output end of the motor four. A mounting bracket is threaded onto the lead screw two. The mounting bracket includes a horizontal plate with a reinforcing plate at its upper end. The lead screw two passes through the horizontal plate and the reinforcing plate.

[0012] Preferably, a mounting plate three is provided at the lower end of the horizontal plate, and a motor three is fixedly mounted on the mounting plate three. The output end of the motor three is fixedly connected to a hammer pressing block through a crankshaft connecting rod. The hammer pressing block is made of rubber material and its bottom has an arc-shaped structure.

[0013] Preferably, the lower end of the mounting plate three is connected to a sliding sleeve two via an extension rod, and the sliding sleeve two is slidably connected to the outer wall of the extension rod.

[0014] Preferably, the end of the mounting shaft is provided with a fixing plate for fixing the iron core.

[0015] Preferably, the column sidewall is provided with a sliding groove, and a slider is slidably connected inside the sliding groove. The slider is fixedly connected to the horizontal plate and the reinforcing plate on the sidewall away from the column. A fixing block corresponding to the position of the second lead screw is provided at the upper end of the column, and the upper end of the second lead screw is rotatably connected to the fixing block.

[0016] The present invention also provides a winding method for transformer manufacturing, comprising the following steps: S1: Core installation: Fix the transformer core to be wound on the mounting shaft, adjust the position of the core to align it with the side pressure ring and hammer pressure block, and ensure that the core winding part is in a horizontal state to avoid deviation during the winding process. S2: Wire laying: Fix one end of the winding wire to the starting end of the iron core winding, comb the wire to make it flat, adjust motor two to start, drive screw one to rotate, and drive the base plate to slide along the fixed axis through screw one until the side pressure ring touches the side wall of the wire. The pressure sensor detects the current pressure and transmits it to the external processor. The processor controls motor two to make the side pressure ring initially compact the wire. S3: Winding operation. Start motor one. Motor one drives the mounting shaft and iron core to rotate at a constant speed. The wire is gradually wound around the iron core as the iron core rotates. During the winding process, the side pressure ring expands and contracts adaptively through the spring telescopic rod as the wire winding thickness increases. The pressure sensor detects the pressure between the side pressure ring and the wire in real time. When the pressure deviates from the preset value, the external processor controls motor two to start, driving the side pressure component to move synchronously, always maintaining a constant pressure between the side pressure ring and the wire, ensuring that the wire is wound tightly and without damaging the wire. S4: Auxiliary hammer pressing. When the winding operation is carried out simultaneously, start motor four, which is opposite to the winding direction. Motor four drives screw two to rotate. Through the threaded engagement between screw two and the mounting bracket, the mounting bracket is driven to slide up and down along the slide groove. Adjust the hammer pressing block to the height corresponding to the currently wound wire. Then start motor three. Motor three drives the hammer pressing block to reciprocate through the crankshaft connecting rod to uniformly hammer the wire wound on the iron core. S5: Winding complete. When the wire is wound to the end of the iron core, first turn off motors three and four to stop the hammer pressing operation. Then turn off motor one to stop the winding. Adjust motor two to rotate in the opposite direction to drive the side pressure component away from the iron core, release the pressure of the side pressure ring on the wire, and fix the end of the wire to the winding termination end of the iron core to complete the winding.

[0017] The beneficial effects of this invention are: This invention uses a motor to drive a lead screw to rotate, which in turn drives the column and base plate to move back and forth along a fixed axis. This allows the side pressure assembly to move smoothly along the fixed axis. The side pressure ring makes flexible contact with the wire through a spring telescopic rod. This not only compacts the wire laterally during the winding process but also prevents damage to the wire. It is especially effective for the transition area between the arc and plane of the elliptical iron core, ensuring uniform and stable compaction and guaranteeing the uniformity of the winding.

[0018] This invention uses the start / stop and rotation direction of motor two to drive the side pressure component to move gradually, always maintaining a constant pressure between the side pressure ring and the conductor. Especially when winding an elliptical iron core, it can adapt to the curvature of the elliptical iron core, and uniformly compact the conductor on the arc surface, plane and transition part of the iron core, ensuring that the conductor is tightly wound and not squeezed or damaged, avoiding insufficient compaction or excessive compression in some areas due to the special shape of the iron core.

[0019] This invention uses a fourth motor to drive a second lead screw to rotate, which in turn drives the mounting bracket to flexibly adjust its position. This allows for precise adaptation to the hammering requirements of different arc surfaces, planes, and transition parts of special-shaped iron cores such as ellipses. In conjunction with a third motor, which drives the hammering block to perform reciprocating hammering motion via a crankshaft and connecting rod, this invention ensures uniform hammering of the conductors in various parts of special-shaped iron cores such as ellipses. This effectively avoids damage to the conductor insulation layer, further improving the winding quality of such transformers and reducing conductor loss and rework rate during the production process.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1 and Figure 4 As shown, a winding device for transformer production includes a mounting plate 1. A motor 2 is fixedly mounted on one side wall of the mounting plate 1. The output end of the motor 2 passes through the mounting plate 1 and is coaxially fixedly connected to a mounting shaft 21 for placing the transformer core. A fixing disc 22 for fastening the core is fixedly provided at the end of the mounting shaft 21, which can effectively prevent the core from loosening or shifting during the winding process. It is especially suitable for fixing elliptical cores and avoids shifting due to their special shape during the winding process. A pair of fixing shafts 13 are also symmetrically mounted on the same side wall of the mounting plate 1. The position of the fixing shafts 13 corresponds to that of the mounting shafts 21, and a side pressure component 4 is slidably mounted on the fixing shafts 13 for laterally compacting the conductors during the winding process. For the transition area between the arc surface and the plane of the elliptical core, precise compaction can be achieved, ensuring uniform winding.

[0025] Please see Figures 4-6 As shown, the side-pressure assembly 4 includes a base plate 42. A pair of sliding sleeves 43 are symmetrically fixed at the upper end of the base plate 42. The sliding sleeves 43 are slidably sleeved on the fixed shaft 13, allowing the base plate 42 to slide smoothly along the fixed shaft 13. A spring telescopic rod 44 is fixedly connected to the lower end of the base plate 42. A side-pressure ring 45 is rotatably connected to the lower end of the spring telescopic rod 44 through a bearing. During the winding process, the side-pressure ring 45 always abuts against the side wall of the conductor, achieving flexible compaction of the conductor and preventing damage to the conductor.

[0026] Please see Figure 1 As shown, a second motor 3 is fixedly installed on the side wall of the mounting plate 1 away from the first motor 2. The output end of the second motor 3 is coaxially fixedly connected to a lead screw 31. A column 41 is vertically fixed to the upper end of the base plate 42. The upper end of the column 41 has a threaded hole 413 that matches the lead screw 31. The lead screw 31 is threadedly connected to the threaded hole 413. The second motor 3 drives the lead screw 31 to rotate, which can drive the column 41 and the base plate 42 to reciprocate along the fixed axis 13, thereby realizing the position adjustment of the side pressure component 4.

[0027] A pressure sensor is embedded inside the side pressure ring 45. The pressure sensor is electrically connected to an external processor. The pressure signal detected by the pressure sensor can be transmitted to the external processor in real time. According to the preset pressure value, the external processor controls the start, stop and rotation direction of the motor 3 to drive the side pressure component 4 to move gradually, so as to always maintain a constant pressure between the side pressure ring 45 and the wire. Especially when winding an elliptical iron core, it can adapt to the curvature of the elliptical iron core and uniformly compact the wire on the arc surface, plane and transition part of the iron core, ensuring that the wire is tightly wound and not squeezed or damaged, and avoiding local insufficient compaction or excessive compression due to the special shape of the iron core.

[0028] Specifically, by cooperating with the mounting shaft 21 and the fixing plate 22, the transformer core is firmly fixed, effectively preventing the core from loosening or shifting during winding, adapting to the shape characteristics of the elliptical core, and ensuring the stability of the winding reference. The side pressure assembly 4 can move smoothly along the fixed axis 13. Its side pressure ring 45 achieves flexible contact with the wire through the spring telescopic rod 44, which can both compact the wire laterally during the winding process and avoid damage to the wire. Especially for the transition part between the arc surface and the plane of the elliptical iron core, it can achieve precise compaction and ensure the uniformity of winding. With the help of the pressure sensor embedded in the side pressure ring 45, the external processor and the linkage control of the motor 3, the pressure between the side pressure ring 45 and the conductor can be detected in real time and the position of the side pressure component 4 can be automatically adjusted. The motor 3 drives the lead screw 31 to rotate, which drives the column 41 and the base plate 42 to move along the fixed axis 13, always maintaining constant pressure. It can adapt to the curved surface changes of the elliptical iron core, ensuring that the conductors in all parts of the iron core are tightly wound and not squeezed or damaged. It effectively avoids the problem of insufficient compaction or excessive compression caused by the special shape of the iron core, improves the winding quality and production efficiency of the transformer, and reduces conductor loss and rework rate.

[0029] Please see Figure 1 As shown, the upper end of mounting plate 1 is fixedly connected to mounting plate 2 12 via connecting plate 11. Mounting plate 2 12 is set parallel to mounting plate 1. The end of screw 31 is rotatably connected to the side wall of mounting plate 2 12 via bearing. The upper end of fixed shaft 13 is also fixedly connected to mounting plate 2 12, which further improves the installation stability of screw 31 and fixed shaft 13 and ensures smooth sliding of side pressure assembly 4.

[0030] Please see Figure 4 As shown, two sets of hammer pressing assemblies 5 are symmetrically installed on the upper end of the base plate 42 to assist in hammering the wound wire, further improving the tightness of the winding. The hammer pressing assembly 5 includes a motor 4 55 fixedly installed on the upper end of the base plate 42, and a lead screw 2 56 is coaxially fixedly installed on the output end of the motor 4 55. A mounting bracket 51 is threadedly connected to the lead screw 2 56. The mounting bracket 51 includes a horizontal plate 511 and a reinforcing plate 512 fixedly installed on the upper end of the horizontal plate 511. The lead screw 2 56 passes through the horizontal plate 511 and the reinforcing plate 512. The reinforcing plate 512 can improve the structural strength of the mounting bracket 51 and prevent deformation during the hammer pressing process.

[0031] Please see Figure 6 As shown, a mounting plate 514 is fixedly installed at the lower end of the horizontal plate 511. A motor 53 is fixedly installed on the mounting plate 514. The output end of the motor 53 is fixedly connected to a hammer pressing block 54 through a crankshaft connecting rod 52. The hammer pressing block 54 is made of flexible rubber material, and its bottom has an arc-shaped structure adapted to the wire, which can not only achieve uniform hammer pressing on the wire, but also effectively avoid damage to the wire insulation layer.

[0032] Please see Figures 7-8 As shown, an extension rod 515 is fixedly connected to the lower end of the mounting plate 3 514. A sliding sleeve 2 516 is slidably sleeved on the outer wall of the extension rod 515. The sliding sleeve 2 516 is fixedly connected to the hammer pressing block 54, which can assist the hammer pressing block 54 to perform reciprocating motion, ensure the stability of the hammer pressing process, and prevent the hammer pressing block 54 from shifting.

[0033] Specifically, the hammer pressing component 5 is fixed to the upper end of the base plate 42 and can move synchronously with the side pressing component 4. It can accurately assist in hammering the wires after the iron cores of special shapes such as elliptical shapes are wound. Together with the lateral compaction effect of the side pressing component 4 on the arc surface, plane and transition part of the iron core, it can effectively make up for the problems of local looseness and gaps that are easy to occur when winding iron cores of special shapes, further improve the tightness of the wire winding, and ensure the structural stability of the iron cores of special shapes such as elliptical shapes. The hammer pressing assembly 5 is driven by motor 4 55 to rotate lead screw 2 56, which drives the mounting frame 51 to flexibly adjust its position. It can accurately adapt to the hammer pressing requirements of different arc surfaces, planes and transition parts of special-shaped iron cores such as elliptical ones. In addition, the reinforcing plate 512 on the mounting frame 51 effectively improves its own structural strength, avoids deformation of the mounting frame 51 during the hammer pressing process, and ensures the stability of hammer pressing operation on special-shaped iron cores. Motor 3 53 drives hammer block 54 to perform reciprocating hammering motion through crankshaft connecting rod 52. The cooperation between extension rod 515 and sliding sleeve 2 516 can assist hammer block 54 to move smoothly and prevent it from deviating, ensuring uniform hammering of conductors in various parts of elliptical and other special-shaped iron cores. The hammer pressing block 54 is made of flexible rubber material and has an arc-shaped structure at the bottom that is compatible with the conductor. It can achieve precise and uniform hammer pressing on the conductors of special-shaped iron cores such as elliptical ones, while effectively avoiding damage to the conductor insulation layer. It takes into account both the hammer pressing effect and conductor protection. It is specially adapted to the winding characteristics of special-shaped iron cores such as elliptical ones, further improving the winding quality of such transformers and reducing conductor loss and rework rate during the production process.

[0034] The side wall of the column 41 is provided with a sliding groove 411, and a slider 513 is slidably connected inside the sliding groove 411. The side wall of the slider 513 away from the column 41 is fixedly connected to the horizontal plate 511 and the reinforcing plate 512, realizing the sliding cooperation between the mounting bracket 51 and the column 41 and improving the stability of the vertical movement of the mounting bracket 51. A fixing block 412 is fixedly installed at the upper end of the column 41. The position of the fixing block 412 corresponds to the lead screw 56. The upper end of the lead screw 56 is rotatably connected to the fixing block 412 through a bearing, further improving the installation stability of the lead screw 56.

[0035] Please see Figures 1-3 As shown, the present invention also provides a winding method for transformer manufacturing, comprising the following steps: S1: Core installation: Fix the transformer core to be wound on the mounting shaft 21, adjust the position of the core so that it is aligned with the side pressure ring 45 and the hammer pressure block 54, and ensure that the core winding part is in a horizontal state to avoid deviation during the winding process. S2: Wire laying: Fix one end of the winding wire to the starting end of the iron core winding, comb the wire to make it flat, adjust motor 2 3 to start, drive lead screw 1 31 to rotate, and drive base plate 42 to slide along fixed shaft 13 through lead screw 1 31 until side pressure ring 45 abuts against the side wall of the wire. Pressure sensor detects the current pressure and transmits it to external processor. The processor controls motor 2 3 to make side pressure ring 45 initially compact the wire; S3: Winding operation. Start motor 2. Motor 2 drives the mounting shaft 21 and the iron core to rotate at a constant speed. The wire is gradually wound around the iron core as the iron core rotates. During the winding process, the side pressure ring 45 expands and contracts adaptively through the spring telescopic rod 44 as the wire winding thickness increases. The pressure sensor detects the pressure between the side pressure ring 45 and the wire in real time. When the pressure deviates from the preset value, the external processor controls motor 3 to start, driving the side pressure component 4 to move synchronously, always maintaining a constant pressure between the side pressure ring 45 and the wire, ensuring that the wire is wound tightly and does not damage the wire. S4: Auxiliary hammer pressing. When the winding operation is carried out simultaneously, the motor 4 55, which is opposite to the winding direction, is started. The motor 4 55 drives the lead screw 2 56 to rotate. Through the threaded engagement between the lead screw 2 56 and the mounting bracket 51, the mounting bracket 51 is driven to slide up and down along the slide groove 411. The hammer pressing block 54 is adjusted to the height corresponding to the wire currently being wound. Then the motor 3 53 is started. The motor 3 53 drives the hammer pressing block 54 to reciprocate through the crankshaft connecting rod 52, and uniformly hammers the wire wound on the iron core. S5: Winding complete. When the wire is wound to the end of the iron core, first turn off motor 3 (53) and motor 4 (55) to stop the hammer pressing operation. Then turn off motor 1 (2) to stop the winding. Adjust motor 2 (3) to rotate in the opposite direction, driving the side pressure component 4 away from the iron core, releasing the pressure of the side pressure ring 45 on the wire, and fixing the end of the wire to the winding termination end of the iron core to complete the winding.

When the wire is wound to the end of the iron core, first turn off motor three (53) and motor four (55) to stop the hammer pressing operation. Then turn off motor one (2) to stop the winding. Adjust motor two (3) to rotate in the opposite direction, drive the side pressure component (4) away from the iron core, release the pressure of the side pressure ring (45) on the wire, fix the end of the wire to the winding termination end of the iron core, and complete the winding.
