Description

Technical Field

[0001] The invention relates to the technical field of transformer manufacturing, and in particular to a winding device for transformer production. Background Art

[0002] Transformers are basic equipment for power transmission and distribution, mainly composed of primary windings, secondary windings and iron cores. The coil windings are wound with enameled wires, which are prone to surface paint peeling and damage due to factors such as transportation. If such defects are not discovered in time and directly enter the winding process, they will lead to incorrect transformer operating parameters and even leakage problems, which will undoubtedly cause considerable losses to manufacturers and reduce production efficiency. Summary of the invention

[0003] The present invention provides a winding device for transformer production. During the winding process of the coil winding, the insulation performance of the enameled wire drawn from the material roll is monitored in real time through an insulation monitoring device, so that the defective parts of the enameled wire are completely repaired before being wound into the coil frame, thereby ensuring the final insulation effect of the coil winding.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a winding equipment for transformer production, comprising: a winding base, wherein the tops of both ends of the winding base are respectively provided with a horizontal first horizontal slide and a second horizontal slide perpendicular to the length direction, and the top of the winding base is located between the first horizontal slide and the second horizontal slide and is fixedly provided with a wire-out bracket and a wire-receiving bracket, the top of the wire-out bracket is provided with an insulation monitoring device, and the top of the wire-receiving bracket is provided with an internal repair device; a material unwinding stand, wherein the material unwinding stand is arranged on the first horizontal slide, and the material unwinding stand is provided with a material roll and a material unwinding motor for driving the material roll; a material winding stand, wherein the material winding stand is arranged on the second horizontal slide, and the material winding stand is provided with a reel and a material winding motor for driving the reel, and the outer side of the reel is provided with a coil frame; a controller, wherein the first horizontal slide, the second horizontal slide, the material unwinding motor, the material winding motor, the insulation monitoring device and the internal repair device are electrically connected to the controller respectively.

[0005] Preferably, the insulation monitoring device includes an ignition coil and a metal tube horizontally arranged on the top of the wire outlet bracket; the primary of the ignition coil is electrically connected to the controller through an ignition circuit, and the secondary of the ignition coil is electrically connected between the metal tube and the material roll.

[0006] Preferably, the internal repair device includes a first glue groove fixedly arranged on the wire take-up bracket near one end of the material unloading stand, a first glue dipping brush is provided inside the first glue groove, a first servo motor is provided on the top of the first glue groove, and the first glue dipping brush is connected to the output shaft of the first servo motor through a rocker arm; it also includes an electric heating tube, which is horizontally arranged at one end of the first glue groove corresponding to the material coiling stand; the first servo motor and the electric heating tube are electrically connected to the controller respectively.

[0007] Preferably, the winding base is provided with an external repair bracket corresponding to the bottom of the coil stand, a second glue groove is provided on the top of the external repair bracket, a second glue dipping brush is provided inside the second glue groove, a second servo motor is provided on the top of the second glue groove, and the second glue dipping brush is connected to the output shaft of the second servo motor through a rocker arm; a hot air dryer is provided on the side of the external repair bracket close to the wire take-up bracket, and the air outlet of the hot air dryer faces the reel; the second servo motor and the hot air dryer are electrically connected to the controller respectively.

[0008] Preferably, the output shaft sleeve of the unloading motor is provided with an unloading shaft sleeve, and a coil spring is provided between the output shaft of the unloading motor and the unloading shaft sleeve; the material coil is spline-fitted to the outside of the unloading shaft sleeve.

[0009] Preferably, the bottom of the first horizontal slide table and the second horizontal slide table are respectively provided with a horizontal slide rail and an electric cylinder arranged parallel to the horizontal slide rail. The first horizontal slide table and the second horizontal slide table are respectively connected to the winding base through the corresponding electric cylinder, and each electric cylinder is electrically connected to the controller.

[0010] The invention has the beneficial effect that: during the winding process of the coil winding, the insulation monitoring device monitors the insulation performance of the enameled wire drawn from the material roll in real time. Once the insulation problem of the enameled wire is detected, the controller immediately starts the internal repair device to repair the enameled wire at the damaged position, and at the same time reduces the working speed of the discharge motor and the winding motor, so that the defective part of the enameled wire is completely repaired before being wound into the coil skeleton, thereby ensuring the final insulation effect of the coil winding. The insulation monitoring device uses a corona method to detect the integrity of the outer skin of the enameled wire, wherein the metal tube and the enameled wire itself are respectively connected to the ignition coil, and there is a high potential difference between the two. When the outer skin of the enameled wire is good, it can pass through the metal tube normally, and no corona discharge phenomenon will occur, and the working current of the ignition circuit remains stable; when the outer skin of the enameled wire is damaged, sparks are generated between the enameled wire and the metal tube, and the working current of the ignition circuit changes, and the controller coordinates the work of the internal repair device, the discharge motor and the winding motor according to the state feedback of the ignition circuit, thereby completing the partial repair of the enameled wire. The internal repair device uses the first servo motor to flip the first dipping brush upward and contact the enameled wire, so as to achieve the application of insulating glue oil to the bottom of the enameled wire. When the enameled wire passes through the electric heating tube, it is heated and dried, so that the insulating glue oil solidifies to form a complete insulating layer, thereby completing the repair process of the outer skin of the enameled wire. Finally, the repaired enameled wire is stably wound on the coil skeleton as the reel rotates, and the effect of inner insulation is achieved. The second dipping brush cooperates with the first dipping brush to work. When the defective position repaired by the first dipping brush reaches the bottom of the reel, the second servo motor lifts the second dipping brush under the action of the controller and contacts the enameled wire position at the bottom of the reel, so that the insulating glue oil is applied to the outside of the defective part of the enameled wire, and the position is dried by the hot air dryer, and a new insulating layer is formed on the outside of the enameled wire. In addition, the unwinding motor and the winding motor can be implemented by a stepper motor, thereby ensuring good speed control capability. For the position detection of the enameled wire, the length of the enameled wire can be collected by an encoder added to the outlet wheel, thereby ensuring the repair position accuracy of the internal repair device, and the external repair device can be linked with the internal repair device to ensure the coverage of the outer repair position of the enameled wire. The coil spring eliminates the linear speed difference generated by the enameled wire during the winding process of the coil skeleton, and ensures the overall winding tension of the enameled wire. The replaceable reel can be adapted to a variety of coil skeletons of different specifications through its outer wall cross-sectional profile. During the winding process of the enameled wire, the controller slides the first horizontal slide and the second horizontal slide left and right through two electric cylinders, thereby ensuring that the extraction position of the enameled wire is always aligned with the metal tube, and avoids contact with the inner wall of the metal tube through the angle adjustment of the outlet wheel, while also reducing the friction of the outer sheath of the enameled wire and avoiding the chance of damage to the outer skin; and during the winding process of the coil skeleton, the winding position of the enameled wire is positioned by the winding wheel, and the winding base sliding left and right allows the enameled wire to be evenly wound on the coil skeleton.

DETAILED DESCRIPTION

[0017] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] according to Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a winding device for transformer production comprises: a winding base 1, wherein the tops of both ends of the winding base 1 are respectively provided with a horizontal first horizontal slide 2 and a second horizontal slide 3 perpendicular to the length direction, and the top of the winding base 1 is located between the first horizontal slide 2 and the second horizontal slide 3 and is fixedly provided with a wire outlet bracket 4 and a wire take-up bracket 5, the top of the wire outlet bracket 4 is provided with an insulation monitoring device, and the top of the wire take-up bracket 5 is provided with an internal repair device; a material discharge rack 6, the material discharge rack 6 is arranged on the first horizontal slide 2, and The unwinding stand 6 is provided with a material roll 7 and a unwinding motor 8 for driving the material roll 7; a coiling stand 9, which is arranged on the second horizontal slide 3, and is provided with a reel 10 and a reel motor 11 for driving the reel 10, and the reel 10 is provided with a coil frame 12 on the outside; a controller, the first horizontal slide 2, the second horizontal slide 3, the unwinding motor 8, the reel motor 11 and the insulation monitoring device and the internal repair device are electrically connected to the controller respectively.

[0019] Through the above-mentioned arrangement, during the winding process of the coil winding, the insulation monitoring device monitors the insulation performance of the enameled wire drawn from the material roll 7 in real time. Once it is detected that there is an insulation problem with the enameled wire, the internal repair device is immediately started by the controller to repair the enameled wire at the damaged position. At the same time, the operating speed of the unwinding motor 8 and the winding motor 11 is reduced, so that the defective parts of the enameled wire are completely repaired before being wound into the coil frame 12, thereby ensuring the final insulation effect of the coil winding.

[0020] The insulation monitoring device includes an ignition coil and a metal tube 13 horizontally arranged on the top of the outlet bracket 4; the primary of the ignition coil is electrically connected to the controller through an ignition circuit, and the secondary of the ignition coil is electrically connected between the metal tube 13 and the material roll 7.

[0021] The device uses a corona method to detect the integrity of the outer skin of the enameled wire, wherein the metal tube 13 and the enameled wire itself are respectively connected to the ignition coil, and there is a high potential difference between the two. When the outer skin of the enameled wire is good, it can pass through the metal tube 13 normally, and no corona discharge will occur, and the working current of the ignition circuit remains stable; when the outer skin of the enameled wire is damaged, sparks are generated between the enameled wire and the metal tube 13, and the working current of the ignition circuit changes, and the controller coordinates the work of the internal repair device, the discharge motor 8 and the winding motor 11 according to the state feedback of the ignition circuit, thereby completing the local repair of the enameled wire.

[0022] The internal repair device includes a first glue groove 15 fixedly arranged at one end of the wire take-up bracket 5 close to the material unloading stand 6, a first glue dipping brush 16 is arranged inside the first glue groove 15, a first servo motor 17 is arranged on the top of the first glue groove 15, and the first glue dipping brush 16 is connected to the output shaft of the first servo motor 17 through a rocker arm; it also includes an electric heating pipe 18, and the electric heating pipe 18 is horizontally arranged at one end of the first glue groove 15 corresponding to the coil stand 9; the first servo motor 17 and the electric heating pipe 18 are electrically connected to the controller respectively.

[0023] When the device is in the repairing state, the first servo motor 17 flips the first dipping brush 16 upwards and contacts the damaged section of the enameled wire, thereby applying insulating glue oil to the bottom of the enameled wire. When the glue-coated enameled wire passes through the electric heating tube 18, it is heated and dried to solidify the insulating glue oil to form a complete insulating layer, thereby completing the repair process of the enameled wire outer skin. Finally, the repaired enameled wire is stably wound on the coil skeleton 12 as the reel 10 rotates, and the effect of inner insulation is achieved.

[0024] In addition, the winding base 1 is provided with an external repair bracket 20 at the bottom corresponding to the coil stand 9, and a second glue groove 21 is provided at the top of the external repair bracket 20, and a second glue dipping brush 23 is provided inside the second glue groove 21, and a second servo motor 22 is provided at the top of the second glue groove 21, and the second glue dipping brush 23 is connected to the output shaft of the second servo motor 22 through a rocker arm; a hot air dryer 24 is provided on the side of the external repair bracket 20 close to the wire take-up bracket 5, and the air outlet of the hot air dryer 24 faces the reel 10; the second servo motor 22 and the hot air dryer 24 are electrically connected to the controller respectively.

[0025] In this setting, the second dipping brush 23 cooperates with the first dipping brush 16 to work. When the defective position repaired by the first dipping brush 16 reaches the bottom of the reel 10, the second servo motor 22 lifts the second dipping brush under the action of the controller and contacts the enameled wire position at the bottom of the reel 10, so that the insulating glue oil is applied to the outside of the defective part of the enameled wire, and the position is dried by the hot air dryer 24, and a new insulating layer is formed on the outside of the enameled wire.

[0026] In the above structure, the unwinding motor 8 and the winding motor 11 can be implemented by stepping motors to ensure good speed control capability. For the position detection of the enameled wire, the length of the enameled wire can be collected by an encoder added to the wire outlet wheel 14, thereby ensuring the repair position accuracy of the internal repair device, and the external repair device can be linked with the internal repair device to ensure the coverage of the outer repair position of the enameled wire.

[0027] The output shaft sleeve of the unloading motor 8 is provided with an unloading shaft sleeve 25 , and a coil spring 26 is provided between the output shaft of the unloading motor 8 and the unloading shaft sleeve 25 ; the material roll 7 is spline-fitted on the outside of the unloading shaft sleeve 25 .

[0028] The coil spring 26 in this arrangement eliminates the linear speed difference generated during the winding process of the enameled wire on the coil frame 12, and ensures the overall winding tension of the enameled wire. The replaceable reel 10 can be adapted to a variety of coil frames 12 of different specifications through its outer wall cross-sectional profile.

[0029] The bottom of the first horizontal slide 2 and the second horizontal slide 3 are respectively provided with a horizontal slide rail and an electric cylinder 27 arranged parallel to the horizontal slide rail. The first horizontal slide 2 and the second horizontal slide 3 are respectively connected to the winding base 1 through the corresponding electric cylinder 27, and each electric cylinder 27 is electrically connected to the controller.

[0030] Through the above structure, during the winding process of the enameled wire, the controller causes the first horizontal slide 2 and the second horizontal slide 3 to slide left and right through the two electric cylinders 27, thereby ensuring that the withdrawal position of the enameled wire is always aligned with the metal tube 13, and avoiding contact with the inner wall of the metal tube 13 by adjusting the angle of the wire outlet wheel 14, while also reducing the friction of the outer sheath of the enameled wire and avoiding the chance of damage to the outer skin; and during the winding process of the coil skeleton 12, the winding position of the enameled wire is positioned by the winding wheel 19, and the winding base 1 that slides left and right allows the enameled wire to be evenly wound on the coil skeleton 12.

[0031] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
