Description

Technical Field

[0001] The invention relates to the technical field of transformer coil processing, in particular to a synchronous processing device for a double-winding coil of a transformer. Background Art

[0002] As a key component of a transformer, the performance of the inductor directly impacts the transformer's overall reliability and safety. Currently, most common inductors on the market use a single-winding structure. These single-winding coils have insufficient high-voltage resistance when operating in high-voltage environments, making it difficult to meet the growing demands for high-voltage transmission and high-power conversion.

[0003] To improve the high-voltage resistance of inductor coils, existing technologies attempt to connect two single-winding coils to form a dual-winding structure. This process involves cutting the coils after the winding machine completes processing, and then welding the two single-winding coils together. This process has the following drawbacks:

[0004] 1. The double-winding coil formed by welding connection is not a true integrated structure. The resistance of the weld is large when current passes through, resulting in a significant increase in heat generation. This not only reduces the efficiency of the coil, but also poses a safety hazard such as fire due to overheating.

[0005] 2. The extended pins of the coil wound by the winding machine are arranged at an acute angle to the coil body. This layout makes it inconvenient to operate the subsequent extended pins during wiring. The wiring part is too close to the coil, which can easily cause safety accidents due to insulation failure or arc discharge, posing a safety hazard. Summary of the Invention

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0053] Embodiment: The present invention provides a technical solution for a synchronous processing device for a double-winding coil for a transformer, such as Figures 1-15 Shown, including:

[0054] A feeder 1 for releasing the wound metal strip;

[0055] The guiding mechanism 2 is provided at the output end of the feeder 1 and is used to transfer and guide the metal strip;

[0056] The first winding assembly 3 includes a first lower base 31, which is positioned at the output end of the guide mechanism 2. A first rolling module 32 is disposed above the first lower base 31. The first rolling module 32 is configured to wind a first winding 91a around the end of the metal strip output by the guide mechanism 2. The first rolling module 32 includes a first bending member configured to bend an overhanging portion of the first winding 91a into a winding pin 93a.

[0057] The second winding assembly 5 includes a second lower base 51, which is positioned at the output end of the first winding assembly 3. The first lower base 31 and the second lower base 51 are positioned on either side of the metal strip. A second rolling module 52 is positioned above the second lower base 51. The second rolling module 52 is used to wind the reserved section 94a of the first winding 91a into the second winding 92a to produce the double-winding coil 9a. The first winding 91a and the second winding 92a form a single metal strip. The second rolling module 52 has a built-in second bending component, which is used to bend the extended portion of the second winding 92a into the winding pin 93a.

[0058] The transfer mechanism 4 includes a transfer table 41 and a support assembly. The transfer table 41 is placed at the output end of the second winding assembly 5. The support assembly is installed on the surface of the transfer table 41. The support assembly is used to transfer the first winding 91a to the transfer table 41 and pull out a reserved section 94a of a specified length, so that the end of the reserved section 94a is placed on the surface of the second lower seat 51.

[0059] The cutting assembly 6 is placed between the first winding assembly 3 and the second winding assembly 5 and is used to cut the metal strip after the support assembly pulls out the reserved section 94a;

[0060] The unloading mechanism is placed on both longitudinal sides of the second winding assembly 5 to automatically push out the double-winding coil 9a.

[0061] In the above scheme:

[0062] 1. The first winding assembly 3 is used to wind and process the first winding 91a. After the first winding 91a is completed, the support assembly is used to transfer the first winding 91a and the metal strip. The cutting assembly 6 is used to cut the metal strip, leaving a reserved section 94a of the metal strip on the transfer table 41. The second winding assembly 5 is used to rotate the reserved section 94a to produce the double-winding coil 9a.

[0063] 2. While the second winding assembly 5 is winding the second winding 92a, the first winding assembly 3 can normally wind the first winding 91a of the next double-winding coil 9a, thus ensuring production continuity;

[0064] 3. After direct winding, the extended pins of the coil are arranged at an acute angle to the coil, which makes subsequent wiring of the extended pins inconvenient. The wiring part is too close to the coil, posing a safety hazard. To solve this problem, the following design is proposed:

[0065] The first bending component and the second bending component can bend the protruding part of the metal strip into the winding pin 93a in the early stage of winding, making the processing of the winding pin 93a easier and eliminating the need for subsequent separate processing; during the winding process, the first bending component and the second bending component can drive the winding pin 93a to rotate, making the winding smoother.

[0066] In a preferred embodiment, the guide mechanism 2 includes a support platform 21, with conveyor rollers 22 and a cleaning seat 23 arranged sequentially along the conveying direction. The metal strip passes through the conveyor rollers 22 and the cleaning seat 23. A negative pressure box 231 is located at the bottom of the cleaning seat 23 to remove dust from the surface of the metal strip. The conveyor rollers 22 convey the metal strip to meet the feeding requirements, and the negative pressure box 231 generates a negative pressure within the cleaning seat 23, thereby removing dust and impurities adhering to the surface of the metal strip.

[0067] As a preferred embodiment, an insertion hole 311 is defined within the first lower base 31. The first rolling module 32 includes a winding post 328, a baffle 321, and a first bending component. The winding post 328 is inserted into the insertion hole 311. A baffle 321 is provided at the top of the winding post 328. A first motor 326 is provided on the top surface of the baffle 321. A first driving rod 327 is provided vertically on the top surface of the first motor 326.

[0068] In order to enable the first bending component to achieve the above-mentioned automatic bending effect, the following solution is given: the first bending component includes a second motor 323, a rotating rod 324 and a restraining cover 325, the outer wall of the baffle 321 is provided with a swinging groove 322, one end of the rotating rod 324 is placed in the swinging groove 322, the top surface of the baffle 321 is provided with a second motor 323 that drives the rotating rod 324 to rotate, and the bottom surface of the outer end of the rotating rod 324 is provided with a restraining cover 325; the inner side of the surface of the first lower seat is provided with a first outer blocking column 33. The first motor 326 can be used to drive the winding column to rotate. At the initial stage of processing, the second motor 323 drives the rotating rod 324 to rotate along the swing groove 322, and the restraining cover 325 can drive the protruding part of the metal belt to rotate. The first outer blocking column 33 can be used to reversely resist the protruding part of the metal belt, so that the winding pin 93a can be bent and processed; when the first motor 326 drives the baffle 321 to rotate, the second motor 323 does not work, and the baffle 321 and the first lower seat 31 cooperate to clamp the metal belt, so that the metal belt rotates and is then wound on the winding column, and the restraining cover 325 also drives the winding pin 93a to rotate; the first driving rod 327 can drive the winding column to rise and fall, so that the winding column rotates and rises at the same time.

[0069] As a preferred embodiment, a negative pressure pump 329 is provided on the surface of the baffle 321, and the negative pressure pump 329 is connected to the adsorption orifice plate 3291, and the adsorption orifice plate 3291 is flush with the bottom surface of the baffle 321; during the primary rolling, the negative pressure pump generates negative pressure at the adsorption orifice plate, and the adsorption orifice plate can adsorb the metal strip extending from the bottom, so that when the baffle and the winding column rotate, the metal strip can be stably driven to be wound.

[0070] As a preferred embodiment, the first rolling module 32 and the second rolling module 52 utilize the same structure, the first bending component and the second bending component utilize the same structure, and a second outer blocking column 54 is provided on the inner side of the surface of the second lower seat 51. A seventh driving rod 53 is provided at the bottom of the second outer blocking column 54, and the second outer blocking column 54 descends when the support assembly moves. In the above scheme, the working steps of the first rolling module 32 are the same as those of the first rolling module 32, but the provision of the second outer blocking column 54 affects the translation of the support assembly. Therefore, the second outer blocking column 54 is designed to be a liftable structure. The fourth driving rod 84 at the bottom can drive the second outer blocking column 54 to descend before the support assembly moves, so that the second outer blocking column 54 is flush with the second lower seat 51.

[0071] In order to enable the supporting assembly to achieve the above-mentioned effect of automatically transferring the first winding 91a, the following solution is given: the supporting assembly includes a horizontal guide rail 42 and a fixed plate 48. The horizontal guide rail 42 is vertically arranged on the outer edge of the surface of the transfer platform 41. The inner wall of the horizontal guide rail 42 is slidably installed with an L-shaped mobile support frame 43. The end of the mobile support frame 43 is connected to the support plate 44. The support plate 44 is horizontally placed on the surface of the transfer platform 41. A base 441 is provided on one side of the surface of the support plate 44. A flip shaft 45 is axially rotatably installed inside the base 441. One end of the flip shaft 45 is vertically connected to the anti-slip plate 46 and the other end is provided with a driven gear 451. The baffle 32 1 is provided with a notch 461 for avoiding the metal belt, and a third motor 47 for driving the driven gear 451 to rotate is installed at the end of the movable support frame 43; the anti-slip plate 46 rotates outward to allow the first winding 91a to move onto the support plate 44; the anti-slip plate 46 rotates inward onto the support plate 44 to resist the first winding 91a and follow the movement of the support plate 44; the fixed plate 48 is provided at the top of the inner end of the transfer table 41, and the fixed plate 48 is located on the lateral side of the second rolling module 52. The bottom surface of the fixed plate 48 is vertically provided with a fifth driving rod 491, and the bottom end of the fifth driving rod 491 is connected to the pressure cover 49, and the pressure cover 49 is used to guide the reserved section 94a downward.

[0072] In the above scheme: the support plate 44 can be used as a temporary storage area for the first winding 91a; the third motor 47 can drive the driven gear 451 to rotate, and then drive the flip shaft 45 to rotate, and the flip shaft 45 drives the anti-slip plate 46 to rotate, so that the anti-slip plate 46 can be rotated to one side when receiving the material, and when the support plate 44 moves outward to the transfer table, the anti-slip plate 46 resists the transfer of the first winding 91a; before slitting, the fifth driving rod 491 drives the pressure cover 49 to descend, so that the pressure cover 49 is pressed on the transfer table 41, and the reserved section 94a of the first winding 91a is placed in the pressure cover 49, so that the pressure cover 49 can prevent the reserved section 94a from shifting during slitting, and when the second winding assembly 5 winds the reserved section 94a, the metal strip of the reserved section 94a moves along the pressure cover 49, so that the metal strip moves into the second winding assembly 5 more stably and will not shift.

[0073] As a preferred embodiment, the cutting assembly 6 includes a first longitudinal guide rail 61, with a C-shaped seat 62 slidably mounted on the top of the first longitudinal guide rail 61. A second drive rod 63 is provided at the top of the C-shaped seat 62. A base plate 64 is provided at the bottom end of the second drive rod 63. A cutter 65 is provided in the middle of the bottom surface of the base plate 64, and a spring pressure plate 66 is symmetrically provided on the bottom surface of the base plate 64. When not in use, the cutter 65 moves to the side without affecting the transfer of the first winding 91a. After the transfer of the first winding 91a is completed, the C-shaped seat moves along the first longitudinal guide rail 61, placing the metal strip below the base plate 64. The second drive rod 63 drives the cutter 65 downward, thereby slitting the metal strip. The spring pressure plate 66 can assist in pressing down the metal plate to prevent the metal strip from shifting during slitting.

[0074] In order to automatically remove the finished double-winding coil 9a, the following problems need to be overcome: 1. When not removing the material, it must not affect the transfer of the first winding 91a and the metal strip, nor the operation of the second winding assembly 5; 2. When the double-winding coil 9a is completed, its distribution is irregular, and the material removal assembly 7 needs to correct the posture of the double-winding coil 9a for accurate output;

[0075] The unloading mechanism includes a material picking component 7, which includes a second longitudinal guide rail 71 and a storage table 78. The second longitudinal guide rail 71 is placed above the area between the slitting component and the transfer table 41. A hanging block 72 is slidably installed on the bottom surface of the second longitudinal guide rail 71. A sixth driving rod 73 is vertically provided on the bottom surface of the hanging block 72. The bottom end of the sixth driving rod 73 is vertically connected to a push plate 74. The push plate 74 is placed parallel to the transfer table and placed on the outside of the second lower seat 51. The inner end of the inner wall of the push plate 74 is vertically provided with a first side constraint plate 75. The outer end of the inner wall of the push plate 74 is rotatably connected to the second side constraint plate 76 and a fourth motor 77 is installed at the rotating connection; the second side constraint plate 76 rotates to correct the position of the first winding 91a and the second winding 92a, so that the first winding 91a and the second winding 92a are placed between the first side constraint plate 75 and the second side constraint plate 76. The fifth drive rod 491 is designed to drive the push plate 74 to move up and down. When there is no need to take materials, the sixth drive rod 73 drives the push plate 74 to be lifted up, and the first side constraint plate 75 and the second side constraint plate 76 are lifted up and placed on the outside of the second rolling module 52. This will not affect the operation of the second rolling module 52, nor will it affect the translation of the material support assembly; when pushing materials, the sixth drive rod 73 drives the push plate 74 to descend, and the fourth motor 77 can drive the second side constraint plate 76 to rotate, so that the second side constraint plate 76 can contact the regular double-winding coil 9a to facilitate the precise insertion of the subsequent internal support 9.

[0076] As a preferred embodiment, a storage platform 78 is provided on the inner longitudinal sidewall of the transfer platform 41. The storage platform 78 and the push plate 74 are respectively positioned on the longitudinal sides of the second lower base 51. A longitudinal block 781 and a transverse block 782 are provided on the surface edge of the storage platform 78. The transverse block 782 is used to laterally stop the double-winding coil 9a. The interior of the longitudinal block 781 defines a groove 7811 for inserting the first side restraining plate 75. The double-winding coil 9a pushed out by the push plate 74 enters the storage platform 78. The transverse block 782 and the longitudinal block 781 increase the restraining area and further organize the double-winding coil 9a.

[0077] The double-winding coil 9a is easily deformed locally during the transfer process. In order to ensure the regularity of the shape of the double-winding coil 9a, the following solution is provided:

[0078] As a preferred embodiment, the unloading mechanism also includes an insertion assembly 8, which includes a third driving rod 81. The bottom end of the third driving rod 81 is connected to the first hanging plate 82. The bottom surface of the first hanging plate 82 is provided with a hanging column 83 and a fourth driving rod 84. The bottom end of the hanging column 83 is provided with a second hanging plate 85. The outer wall of the hanging column 83 is slidably installed with a movable ring 86. The top surface of the movable ring 86 is connected to the output end of the fourth driving rod 84. The outer wall of the movable ring 86 is hinged with multiple groups of rocking rods 861. The bottom end of the rocking rod 861 is hinged with a claw 87. The interior of the second hanging plate 85 is provided with multiple groups of sliding holes 851. Each group of claws 87 vertically penetrates the sliding hole 851. The claw 87 is L-shaped. A positioning column 88 is provided at the center of the bottom surface of the second hanging plate 85. The side wall of the positioning column 88 is provided with a rib 881. The lifting and lowering of the movable ring 86 can drive the rocker arm 861 to open and close. When the movable ring 86 is lifted, the claws 87 can be driven to move horizontally inward. Multiple sets of claws 87 can quickly clamp and position the inner support member 9 in the early stage; and when the inner support member 9 is inserted into the double-winding coil 9a, the movable ring 86 descends, causing the claws 87 to detach from the inner support member 9.

[0079] As a preferred embodiment, the inner support member 9 includes a rectangular tube 91, which is plugged into the positioning column 88. The inner wall of the rectangular tube 91 is provided with a rib groove 911 that adapts to the rib 881. The four sides of the rectangular tube 91 are provided with a spring rod 92. The outer end of the spring rod 92 is provided with an arc support plate 93. The bottom end of the arc support plate 93 is a chamfered structure. The top of the arc support plate 93 is vertically provided with an outer folding plate 94. The top surface of the outer folding plate 94 is provided with a clamping frame 95. The bottom end of the clamping claw 87 is inserted into the clamping frame 95 to drive each group of arc support plates 93 to retract. The elastically retractable arc support plates 93 are designed to retract when waiting for material loading. This allows the overall outer diameter of the arc support plates 93 to be smaller than the inner diameter of the winding, facilitating insertion of the inner support member 9 into the dual-winding coil 9a. Once inserted, the movable ring 86 descends and unlocks, allowing the spring rod 92 to drive the arc support plates 93 outward to contact the dual-winding coil 9a, ensuring its stability. The ribs 881 and rib grooves 911 work together to ensure quick and precise insertion of the inner support member 9.

[0080] The processing device, when implemented, includes the following steps:

[0081] S1, the first stage of feeding:

[0082] The feeder 1 releases the metal strip, and the conveyor roller 22 conveys the metal strip. The metal strip passes through the cleaning seat 23, which removes dust from the metal strip. The metal strip is then conveyed to the first lower seat 31, extends a certain distance, and stops. The end of the metal strip is placed between the first outer stop column 33 and the insertion hole 311.

[0083] S2. Processing of the first winding 91a:

[0084] The first drive rod 327 drives the winding post to be inserted into the insertion hole 311. The baffle 321 contacts the metal strip. The restraining cover 325 is pressed down to cover the protruding portion of the metal strip. The end of the metal strip is placed between the first outer baffle 33 and the winding post. The second motor 323 drives the rotating rod 324 to rotate along the swing slot 322. The restraining cover 325 drives the protruding portion of the metal strip to rotate. The first outer baffle 33 can be used to reversely contact the protruding portion of the metal strip, thereby bending the winding pin 93a.

[0085] The first motor 326 drives the baffle 321 and the winding column to rotate, and the suction plate attracts the metal strip, causing it to be wound around the winding column. The restraining cover 325 also drives the winding pin 93a to rotate accordingly. After the first winding is completed, the first driving rod 327 drives the winding column to rotate and lift upward, and the metal strip is wound around the winding column until the first winding 91a is completed.

[0086] S3, the winding column is reversed and lifted up, so that the winding column is separated from the first winding 91a;

[0087] S4, second stage feeding:

[0088] The movable support frame 43 moves along the transverse guide rail 42, so that the support plate 44 moves to one side of the lower seat body, and the support plate 44 is flush with the lower seat body. The third motor 47 drives the flip shaft 45 to rotate, so that the anti-slip plate 46 rotates outward to one side;

[0089] The conveying roller 22 conveys the metal strip, transferring the first winding 91a to the support plate 44; the anti-slip plate 46 rotates inward to the side of the first winding 91a;

[0090] The support plate 44 moves to the transfer table 41, and the conveyor roller 22 continues to convey the metal strip. The anti-slip plate 46 stops the first winding 91a on the support plate 44 until the first winding 91a moves to the outer end of the transfer table 41 and pulls out the reserved section 94a of the specified length.

[0091] S5, cutting:

[0092] The fifth driving rod 491 drives the pressing cover 49 to move downward, and the pressing cover 49 covers the transfer platform 41, and the reserved section 94a is placed in the pressing cover 49;

[0093] The C-shaped seat moves along the first longitudinal guide rail 61, the bottom plate 64 moves to the bottom of the metal strip, the second driving rod 63 drives the cutter 65 to descend, the spring pressure plate 66 presses down the metal strip, and the cutter 65 cuts the metal strip;

[0094] The conveying roller 22 and the feeder 1 are reversed to reel the metal strip, thereby adjusting the length of the metal strip extending beyond the first lower seat 31;

[0095] S6. Processing of the second winding 92a:

[0096] The first winding assembly 3 repeatedly winds the next first winding 91a, and the second winding assembly 5 reverses and repeatedly winds the reserved section 94a into the second winding 92a. At the same time, the anti-slip plate 46 rotates outward. During the winding process of the reserved section 94a, the pressing cover 49 guides the movement of the reserved section 94a. The first winding 91a gradually approaches the second winding assembly 5. In the later stage of production, the pressing cover 49 is lifted. After the second winding 92a is completed, the double-winding coil 9a can be obtained.

[0097] S7, cutting of double winding coil 9a:

[0098] The sixth driving rod 73 drives the push plate 74 downward, and the push plate 74 is placed on one side of the second winding 92a. The fourth motor 77 drives the push plate 74 to rotate, so that the first side restraining plate 75 rotates from a vertical position to a horizontal position and stops on the outside of the second winding 92a.

[0099] The fifth motor drives the second side restraining plate 76 to rotate, and the second side restraining plate 76 contacts the first winding 91a and the second winding 92a to correct the position until the double-winding coil 9a is flush between the first side restraining plate 75 and the second side restraining plate 76;

[0100] The hanging block 72 moves along the second longitudinal guide rail 71, and the first side restraining plate 75 is gradually inserted into the groove 7811 of the longitudinal block 781. The push plate 74 pushes the double-winding coil 9a until the transverse block 782 stops the double-winding coil 9a. The double-winding coil 9a is then placed in the rectangular area enclosed by the longitudinal block 781, the push plate 74, the second side restraining plate 76, and the transverse block 782.

[0101] S8, insert the inner support member 9:

[0102] A set of inner support members 9 is reserved above the first winding 91a and the second winding 92a, and each set of arc support plates 93 is in an inward state and compresses the spring rod 92;

[0103] The third driving rod 81 drives the first hanging plate 82 to descend, so that each set of arc support plates 93 in the retracted state is inserted into the winding, and the outer folding plate 94 contacts the top of the winding;

[0104] The fourth driving rod 84 drives the movable ring 86 to descend along the suspension column 83. When the movable ring 86 descends, it drives the claws 87 to move outward through the swing rod 861. The bottom end of the claw 87 gradually separates from the clamping frame 95. The arc support plate 93 loses the resistance of the claw 87. The spring rod 92 drives the arc support plate 93 to move outward and return to its original position. The four sets of arc support plates 93 can support the winding from the inside, and the inner support member 9 can remain in the double-winding coil 9a.

[0105] The third driving rod 81 drives the first hanging plate 82 to lift up, and the worker lifts up the new inner support 9, so that the positioning column 88 is inserted into the rectangular tube 91, and the rib 881 is inserted into the rib groove 911, and then the fourth driving rod 84 is retracted, so that each group of claws 87 are retracted, and the bottom end of the claw 87 is inserted into the card frame 95 and compresses the arc support plate 93.
