Description

Technical Field

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

[0002] As an important component of a transformer, the performance of an inductance coil directly affects the overall reliability and safety of the transformer. At present, most of the common inductance coils on the market adopt a single-winding structure. When operating in a high-voltage environment, such single-winding coils have insufficient high-voltage resistance performance and are difficult to meet the increasing demands of high-voltage power transmission and high-power conversion. To improve the high-voltage resistance performance of the inductance coil, in the prior art, attempts have been made to connect two single-winding coils to form a double-winding structure. The processing method is as follows: After the winding machine completes the processing of one winding coil, it is cut off, and the two single-winding coils are connected by welding; the following deficiencies exist in this processing method: 1. The double-winding coil formed by the welding connection method is not a truly integrated structure. The resistance at the weld part is large when current passes through, resulting in a significant increase in heat generation, which not only reduces the efficiency of the coil but also poses safety hazards such as fires caused by overheating.

[0003] 2. The outer extension pins of the coil wound by the winding machine are arranged at an acute angle with the coil body. This layout makes the subsequent operation of connecting the outer extension pins inconvenient. The connection part is too close to the coil, and it is easy to cause safety accidents due to insulation failure or arc discharge, posing safety hazards. Summary of the Invention

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments 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] 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 As shown, including: A feeder 1 for releasing the wound metal strip; The guiding mechanism 2 is arranged at the output end of the feeder 1 and is used for transferring and guiding the metal strip; The first winding assembly 3 includes a first lower seat 31, which is placed at the output end of the guide mechanism 2. A first rolling module 32 is provided above the first lower seat 31; the first rolling module 32 is used to wind a first winding 91a at the end of the metal strip output by the guide mechanism 2; the first rolling module 32 has a first bending component built therein, and the first bending component is used to bend the extended portion of the first winding 91a into a winding pin 93a; The second winding assembly 5 comprises a second lower seat 51, which is placed at the output end of the first winding assembly 3, the first lower seat 31 and the second lower seat 51 are located on both sides of the metal strip, and a second rolling module 52 is arranged above the second lower seat 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 obtain the double-winding coil 9a; the first winding 91a and the second winding 92a are a single metal strip; the second rolling module 52 has a second bending component built in, and the second bending component is used to bend the extended portion of the second winding 92a into a winding pin 93a; 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 body 51; A cutting assembly 6, which is disposed between the first winding assembly 3 and the second winding assembly 5, and is used for cutting the metal strip after the support assembly pulls out the reserved section 94a; The unloading mechanism is arranged on both longitudinal sides of the second winding assembly 5 to automatically push out the double-winding coil 9a.

[0019] In the above scheme: 1. The first winding 91a can be wound and processed by using the first winding component 3. After the processing of the first winding 91a is completed, the first winding 91a and the metal strip can be transferred out by using the stock support component, and the cutting component 6 can cut the metal strip, leaving a reserved section 94a of the metal strip on the transfer table 41. By rotating the second winding component 5, the reserved section 94a can be wound to produce a double-winding coil 9a. 2. When the second winding component 5 winds the second winding 92a, the first winding component 3 can normally wind the first winding 91a of the next double-winding coil 9a. In this way, the continuity of production can be ensured. 3. The outstretched pins of the coil after direct winding are arranged at an acute angle with the coil, which makes it inconvenient to connect the outstretched pins subsequently. The wiring part is too close to the coil, posing a safety hazard. To solve this problem, the following design is given: The first bending component and the second bending component can bend the outstretched part of the metal strip against the winding pin 93a at the initial stage of winding, making the processing of the winding pin 93a more convenient without 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 of the winding more smooth.

[0020] As a preferred embodiment, the feeding mechanism 2 includes a support table 21. Along the conveying direction on the surface of the support table 21, a conveying roller 22 and a cleaning seat 23 are sequentially arranged. The metal strip passes through the conveying roller 22 and the cleaning seat 23 in sequence. A negative pressure box 231 is provided at the bottom of the cleaning seat 23, and the cleaning seat 23 is used to remove the dust on the surface of the metal strip. The conveying roller 22 can convey the metal strip to meet the feeding requirement, and a negative pressure can be generated in the negative pressure box 231 in the cleaning seat 23 to suck the dust and impurities attached to the surface of the metal strip.

[0021] As a preferred embodiment, an insertion hole 311 is opened inside the first lower seat body 31. The first winding module 32 includes a winding column 328, a baffle 321, and a first bending component. The winding column 328 is inserted into the insertion hole 311 in a matching manner. A baffle 321 is provided at the top end of the winding column 328, and a first motor 326 is provided on the top surface of the baffle 321. A vertically arranged first driving rod 327 is provided on the top surface of the first motor 326. In order to enable the first bending component to achieve the above-mentioned automatic bending effect, the following solution is provided: The first bending component includes a second motor 323, a rotating rod 324, and a constraint cover 325. A swinging groove 322 is formed on the outer wall of the baffle 321. One end of the rotating rod 324 is placed in the swinging groove 322. The second motor 323 for driving the rotating rod 324 to rotate is provided on the top surface of the baffle 321. The constraint cover 325 is provided on the bottom surface of the outer end of the rotating rod 324; a first outer retaining post 33 is provided on the inner side of the surface of the first lower seat body. The first motor 326 can 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 swinging groove 322, and the constraint cover 325 can drive the outer extension of the metal strip to rotate. The first outer retaining post 33 can reversely resist the outer extension of the metal strip, 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. The baffle 321 and the first lower seat body 31 cooperate to clamp the metal strip, so that the metal strip rotates and winds around the winding column, and the constraint cover 325 will also drive a part of the winding pin 93a to rotate; the first driving rod 327 can drive the winding column to move up and down, so that the winding column rotates and moves up at the same time.

[0022] As a preferred embodiment, a negative pressure pump 329 is provided on the surface of the baffle 321. The negative pressure pump 329 is connected to an adsorption hole plate 3291, and the adsorption hole plate 3291 is flush-embedded in the bottom surface of the baffle 321; during primary winding, the negative pressure pump generates negative pressure at the adsorption hole plate, and the adsorption hole 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 wind.

[0023] As a preferred embodiment, the first winding module 32 and the second winding module 52 have the same structure, the first bending component and the second bending component have the same structure. A second outer retaining post 54 is provided on the inner side of the surface of the second lower seat body 51. A seventh driving rod 53 is provided at the bottom of the second outer retaining post 54, and the second outer retaining post 54 descends when the material supporting component moves. In the above solution, the working steps of the first winding module 32 are the same as those of the first winding module 32, but the setting of the second outer retaining post 54 will affect the translation of the material supporting component. Therefore, the second outer retaining post 54 is designed to be a liftable structure, and the fourth driving rod 84 at the bottom can drive the second outer retaining post 54 to descend before the material supporting component moves, so that the second outer retaining post 54 is flush with the second lower seat body 51.

[0024] In order to enable the stock support component to achieve the above-mentioned effect of automatically transferring the first winding 91a, the following solution is given: The stock support component includes a horizontal guide rail 42 and a fixing plate 48. The horizontal guide rail 42 is vertically arranged on the outer side edge of the surface of the transfer table 41. An L-shaped moving support frame 43 is slidably installed on the inner wall of the horizontal guide rail 42. The end of the moving support frame 43 is connected to a support plate 44. The support plate 44 is horizontally placed on the surface of the transfer table 41. On one side of the surface of the support plate 44, there is a base 441. An overturning shaft 45 is axially rotatably installed inside the base 441. One end of the overturning shaft 45 is vertically connected to an anti-drop plate 46, and the other end is provided with a driven gear 451. A notch 461 for avoiding the metal strip is opened at the bottom of the baffle 321. A third motor 47 for driving the driven gear 451 to rotate is installed at the end of the moving support frame 43; the anti-drop plate 46 rotates outwards to move the first winding 91a onto the support plate 44; the anti-drop plate 46 rotates inwards onto the support plate 44 to abut against the first winding 91a and move along with the support plate 44; the fixing plate 48 is arranged at the top of the inner end of the transfer table 41. The fixing plate 48 is located on the lateral side of the second coiling module 52. A fifth driving rod 491 is vertically arranged on the bottom surface of the fixing plate 48. The bottom end of the fifth driving rod 491 is connected to a pressing cover 49. The pressing cover 49 is used to press down the guiding reserved section 94a.

[0025] In the above solution: The support plate 44 can be used as a placement and temporary storage area for the first winding 91a; the third motor 47 can drive the driven gear 451 to rotate, and then drive the overturning shaft 45 to rotate. The overturning shaft 45 drives the anti-drop plate 46 to rotate. In this way, the anti-drop plate 46 can rotate to one side during material receiving. When the support plate 44 moves outwards to the transfer table, the anti-drop plate 46 abuts against the first winding 91a for transfer; before slitting, the fifth driving rod 491 drives the pressing cover 49 to descend, so that the pressing cover 49 is pressed onto the transfer table 41. The reserved section 94a of the first winding 91a is placed inside the pressing cover 49. In this way, the pressing cover 49 can prevent the reserved section 94a from shifting during slitting. When the second coiling component 5 coils the reserved section 94a, the metal strip of the reserved section 94a moves along the inside of the pressing cover 49, making the movement of the metal strip into the second coiling component 5 more stable and not shifting.

[0026] As a preferred embodiment, the cutting component 6 includes a first longitudinal guide rail 61. A C-shaped seat 62 is slidably installed on the top of the first longitudinal guide rail 61. A second driving rod 63 is arranged at the top inside the C-shaped seat 62. The bottom end of the second driving rod 63 is provided with a bottom plate 64. A cutting knife 65 is arranged in the middle of the bottom surface of the bottom plate 64. Spring pressing plates 66 are symmetrically arranged on the bottom surface of the bottom plate 64. When not in use, the cutting knife 65 moves to one 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, so that the metal strip is placed below the bottom plate 64. The second driving rod 63 drives the cutting knife 65 to descend, and the slitting of the metal strip can be realized; the spring pressing plates 66 can assist in pressing down the metal plate to prevent the metal strip from shifting during slitting.

[0027] In order to automatically remove the fabricated double-winding coil 9a, the following problems need to be overcome: 1. When not taking the material, it should not affect the transfer of the first winding 91a and the metal strip, nor should it affect the operation of the second winding assembly 5; 2. When the double-winding coil 9a is fabricated, its distribution is irregular, and the material taking assembly 7 needs to correct the posture of the double-winding coil 9a for accurate output. The blanking mechanism includes a material taking assembly 7. The material taking assembly 7 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 assembly and the transfer table 41. A lifting block 72 is slidably installed on the bottom surface of the second longitudinal guide rail 71. A sixth driving rod 73 is vertically provided at the bottom surface of the lifting block 72. The bottom end of the sixth driving rod 73 is vertically connected to a push plate 74. The push plate 74 is parallel to and placed outside the second lower seat body 51 above the transfer table. A first side restraint plate 75 is vertically provided at the inner end of the inner wall of the push plate 74. The outer end of the inner wall of the push plate 74 is rotatably connected to a second side restraint plate 76, and a fourth motor 77 is installed at the rotation connection. The second side restraint plate 76 rotates to correct the positions 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 restraint plate 75 and the second side restraint plate 76. It is designed that the fifth driving rod 491 can drive the push plate 74 to move up and down. When not taking the material, the sixth driving rod 73 drives the push plate 74 to lift, and the first side restraint plate 75 and the second side restraint plate 76 lift and are placed outside the second winding module 52, so that it will not affect the operation of the second winding module 52, nor will it affect the translation of the material supporting assembly; when pushing the material, the sixth driving rod 73 drives the push plate 74 to descend, and the fourth motor 77 can drive the second side restraint plate 76 to rotate, so that the second side restraint plate 76 can abut against and regularize the double-winding coil 9a for the subsequent accurate insertion of the inner support member 9.

[0028] As a preferred embodiment, a storage table 78 is provided on the inner longitudinal side wall of the transfer table 41. The storage table 78 and the push plate 74 are respectively placed on the longitudinal sides of the second lower seat body 51. Longitudinal stop seats 781 and transverse stop seats 782 are provided at the surface edge of the storage table 78. The transverse stop seat 782 is used to horizontally stop the double-winding coil 9a, and a groove 7811 for inserting the first side restraint plate 75 is opened inside the longitudinal stop seat 781. The double-winding coil 9a pushed out by the push plate 74 will enter the storage table 78, and the transverse stop seat 782 and the longitudinal stop seat 781 can increase the restraint area to further regularize the double-winding coil 9a.

[0029] During the transfer of the double-winding coil 9a, it is prone to local compression deformation during the transfer process. In order to ensure the shape regularity of the double-winding coil 9a, the following solutions are given: As a preferred embodiment, the blanking mechanism further includes an insertion assembly 8. The insertion assembly 8 includes a third driving rod 81. The bottom end of the third driving rod 81 is connected to a first hanging plate 82. The bottom surface of the first hanging plate 82 is provided with a hanging post 83 and a fourth driving rod 84. The bottom end of the hanging post 83 is provided with a second hanging plate 85. An activity ring 86 is slidably installed on the outer wall of the hanging post 83. The top surface of the activity ring 86 is connected to the output end of the fourth driving rod 84. A plurality of swing rods 861 are hinged to the outer wall of the activity ring 86. The bottom ends of the swing rods 861 are hinged to claws 87.

The conveying roller 22 conveys the metal strip. The metal strip passes through the cleaning seat 23. The cleaning seat 23 removes the dust on the metal strip. The metal strip is conveyed to the first lower seat body 31 and stops after extending a certain distance. The end of the metal strip is placed between the first outer blocking post 33 and the jack 311. S2. Processing of the first winding 91a: The first driving rod 327 drives the winding column to insert into the jack 311. The baffle 321 contacts the metal strip. The restraint cover 325 presses down and covers the extended part of the metal strip. The end of the metal strip is placed between the first outer retaining post 33 and the winding column. The second motor 323 drives the rotating rod 324 to rotate along the swing slot 322, and then the restraint cover 325 can drive the extended part of the metal strip to rotate. By using the first outer retaining post 33 to resist the extended part of the metal strip in the reverse direction, the winding lead 93a can be bent and processed. The first motor 326 drives the baffle 321 and the winding column to rotate. The adsorption hole plate adsorbs the metal strip, making the metal strip wind around the winding column. The restraint cover 325 also drives the part of the winding lead 93a to rotate accordingly. After the first winding is completed, the first driving rod 327 drives the winding column to rotate and lift at the same time, and the metal strip winds around the winding column until the first winding 91a is processed. S3. The winding column rotates reversely and lifts, so that the winding column is separated from the first winding 91a. S4.

The support plate 44 is flush with the lower seat body. The third motor 47 drives the turnover shaft 45 to rotate, so that the anti - detachment plate 46 rotates outward to one side. The conveying roller 22 conveys the metal strip, so that the first winding 91a is transferred to the support plate 44. The anti - detachment plate 46 rotates inward to one side of the first winding 91a. The support plate 44 moves to the transfer table 41. The conveying roller 22 continues to convey the metal strip. The anti - detachment 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 a reserved section 94a of a specified length is pulled outwards. S5. Slitting: The fifth driving rod 491 drives the pressing cover 49 to move downward. The pressing cover 49 covers the transfer table 41, and the reserved section 94a is placed inside the pressing cover 49. The C - shaped seat moves along the first longitudinal guide rail 61. The bottom plate 64 moves under the metal strip. The second driving rod 63 drives the cutter 65 to descend. The spring pressing plate 66 presses down the metal strip, and the cutter 65 cuts the metal strip. The conveying roller 22 and the feeder 1 rotate reversely to wind up the metal strip. In this way, the length of the metal strip extending out of the first lower seat body 31 is adjusted. S6. Processing of the second winding 92a: The first winding assembly 3 repeats winding the next first winding 91a. The second winding assembly 5 rotates reversely and repeats winding the reserved section 94a into the second winding 92a. At the same time, the anti - detachment plate 46 rotates outward. During the winding 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 produced, the double - winding coil 9a can be obtained. S7, double winding coil 9a cutting: The sixth driving rod 73 drives the push plate 74 to descend, 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 state to a horizontal state and stops at the outer side of the second winding 92a. The fifth motor drives the second side restraint plate 76 to rotate, and the second side restraint plate 76 contacts the first winding 91a and the second winding 92a to correct the position until the double-winding coil 9a is flushly placed between the first side restraint plate 75 and the second side restraint plate 76; The hanging block 72 moves along the second longitudinal guide rail 71, the first side restraining plate 75 is gradually inserted into the groove 7811 of the longitudinal blocking seat 781, and the push plate 74 pushes the double-winding coil 9a to move until the transverse blocking seat 782 stops the double-winding coil 9a, and the double-winding coil 9a can be placed in the rectangular area surrounded by the longitudinal blocking seat 781, the push plate 74, the second side restraining plate 76 and the transverse blocking seat 782; S8, insert the inner support member 9: 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; The third driving rod 81 drives the first hanging plate 82 to descend, so that each group of arc support plates 93 in the retracted state is inserted into the winding, and the outer folding plate 94 abuts against the top of the winding; The fourth driving rod 84 drives the movable ring 86 to descend along the suspension column 83. When the movable ring 86 descends, the swing rod 861 drives the claw 87 to move outward, and 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, and the spring rod 92 drives the arc support plate 93 to move outward and reset. The four groups of arc support plates 93 can support the winding from the inside, and the inner support member 9 can stay in the double winding coil 9a. The third driving rod 81 drives the first hanging plate 82 to lift up, and the worker lifts up the new inner support member 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 clamping frame 95 and compresses the arc support plate 93.
