Description
Technical Field
[0001] The invention relates to the technical field of transformer core processing, in particular to a transformer core winding device and a winding method. Background Art
[0002] During the production and processing of the transformer, in order to realize the electromagnetic induction function of the transformer, it is necessary to wind multiple turns of copper wire on the iron core of the transformer so that the transformer can perform electromagnetic induction operation normally.
[0003] Publication No. CN118016442A discloses a transformer core winding device and a winding method. The problem raised in the background technology is: when the operator operates the transformer core winding machine in the existing equipment to wind the copper wire on the core, the copper wire needs to be replaced after the transformer core is replaced, thereby reducing the continuity of the copper wire winding operation on multiple cores in sequence. In addition, in the prior art, when the copper wire on the package is about to be used up, it is easy to appear that the copper wire has been used up before it is wound on the core, resulting in the need to set a joint on the transformer, thereby affecting the subsequent use quality of the transformer. It rolls up various copper wires onto the receiving cylinder in sequence, and then unwinds the various copper wires using the receiving cylinder, so that the various cores are wound according to the unwinding order of the copper wire by the receiving cylinder.
[0004] Based on the existing technology, there are the following problems:
[0005] When existing transformer core winding equipment winds copper wire on the transformer core, the transformer core is usually clamped and limited by rollers, and then the wire storage ring winds the copper wire on the side wall of the transformer core. In this process, the wire outlet position of the side wall of the wire storage ring needs to pass through the center of the core so that the copper wire is aligned with the center of the core and wound on the side wall of the core to avoid the copper wire being tilted and wound on the side wall of the core, which increases the amount of wire used and further increases the resistance, affecting the use effect of the transformer core. Existing transformer core winding equipment usually adjusts the position of the clamping and limiting core based on the work experience of the staff so that the wire outlet position of the wire storage ring passes through the center of the core. The accuracy is insufficient, and the sizes of the cores are different, which increases the difficulty of adjustment. There are certain shortcomings.

[0032] A winding method for a transformer core winding device, using the transformer core winding device, the method comprises the following steps:
[0033] S1: The transformer core on which the copper wire needs to be wound is limited by the clamping mechanism, so that the roller limits the transformer core and drives the transformer core to rotate at the same time, so that the copper wire is wound on the side wall of the transformer core through the outlet mechanism;
[0034] S2: In the process of clamping the transformer core, the clamping mechanism synchronously drives the adjustment mechanism and the roller to move, so that the center point of the transformer core and the center point of the mounting seat are located on the same vertical line, so that the copper wire passes through the center of the transformer core and is wound on the side wall of the transformer core through the outlet mechanism;
[0035] S3: After clamping is completed, the squeezing force of the roller on the transformer core is adjusted by adjusting the mechanism according to the pressure between the roller and the transformer core, so that during the continuous winding process, the transformer core is continuously limited and driven to rotate, and the center point of the transformer core is vertically aligned with the center point of the mounting base to assist in winding the copper wire.
[0036] The present invention provides a transformer core winding device and a winding method. Compared with the prior art, the present invention has the following beneficial effects:
[0037] 1. The present invention arranges the rollers in a circular array with the center point of the mounting seat, and the outlet position of the outlet mechanism is located on the vertical extension line of the center point of the mounting seat, so that the copper wire is wound through the center point of the transformer core, avoiding the increase of wire consumption due to oblique winding, and avoiding the increase of resistance due to the increase of wire consumption, thereby avoiding affecting the actual use of the transformer. The pressure between the roller and the transformer core is monitored by the adjustment mechanism, and the pressure between the roller and the transformer core is made the same, so that the center point of the transformer core is always or approximately vertically aligned with the center point of the mounting seat, so that the copper wire is always wound through the transformer core, and the clamping mechanism is used to initially position the transformer core on which the copper wire needs to be wound, so that the use of transformer cores of different sizes is convenient, and the adjustment range of the adjustment mechanism is reduced, so as to avoid affecting the accuracy of the adjustment of the adjustment mechanism.
[0038] 2. The present invention adopts the principle of electromagnet like-pole repulsion through an adjusting mechanism, and arranges a pressure sensor between the first electromagnet and the second electromagnet. The pressure between the roller and the transformer core is grasped by the value of the pressure sensor, so that the pressure information is the same, and the position of the roller is adjusted through the first electromagnet, etc., so that the copper wire is always wound around the center point of the transformer core, and the connecting rod and the roller are driven to move, so that the roller can continuously move and maintain a certain pressure with the transformer core during the process of continuously winding the copper wire. Therefore, while limiting the transformer core, the transformer core can be continuously driven to rotate.
[0039] 3. The present invention gradually increases the depth of the detection groove of the monitoring assembly from the end of the guide rod close to the connecting rod to the end far from the connecting rod. As the position of the guide rod changes, there is a difference in the distance information monitored by the ranging sensor, thereby judging the positions of the guide rod and the roller. The position of the roller is judged by monitoring the position of the guide rod, and the position of the roller is adjusted in coordination with the pressure sensor, so that the center point of the transformer core is vertically aligned with the center point of the mounting base, so that the copper wire can be wound around the center point of the transformer core.
[0040] 4. The present invention adjusts the movement of rollers by synchronous linkage through the clamping assembly of the clamping mechanism and the servo motor, so that the rollers are always arranged in a circular array with the center point of the mounting seat, which is convenient for clamping and limiting the transformer core. The transformer core is first clamped and limited, and then adjusted by the adjustment mechanism. It is suitable for use with transformer cores of different sizes, while reducing the adjustment range of the adjustment mechanism to avoid affecting the adjustment accuracy of the adjustment mechanism. The identification component facilitates the position of the rollers arranged in the circular array, and facilitates the subsequent adjustment of the position of a single roller by the separation and combination component.
[0041] 5. The present invention drives the second bevel gear to rise and fall through the separation and combination assembly. When descending, the meshing of the second bevel gear and the first bevel gear is released, so that it is convenient to adjust the position of one of the second sliders and the adjustment mechanism separately. When rising, it is convenient to mesh with the first bevel gear synchronously, so as to facilitate the linkage and rotation of the threaded rod. BRIEF DESCRIPTION OF THE DRAWINGS

An adjusting assembly 53 for adjusting the position of the roller 56 is arranged at the side of the connecting rod 51 away from the outlet mechanism 6.
[0067] See also Fig.10 , Fig.11 and Fig.12 , the adjustment component 53 includes:
[0068] The first electromagnet 532 is fixedly arranged on a side of the connecting rod 51 away from the wire outlet mechanism 6;
[0069] The second electromagnet 531 is fixed on the inner wall of the shell 55 and is arranged opposite to the first electromagnet 532. The side where the first electromagnet 532 and the second electromagnet 531 are close to each other has the same magnetic pole, so as to drive the connecting rod 51 and the roller 56 to move after power is turned on. The inner wall of the first electromagnet 532 is provided with a pressure sensor 534, and the inner wall of the pressure sensor 534 is provided with a guide rod 533. The side wall of the guide rod 533 is provided with a monitoring component 54 for monitoring the position of the roller 56.
[0070] The adjustment mechanism 5 also includes:
[0071] The limiting ring 57 is fixedly sleeved on the side wall of the connecting rod 51 and is located at the top of the housing 55. The bottom of the limiting ring 57 fits with the top of the housing 55. The connecting rod 51 is designed to be convex, and the top of the protruding position of the middle end of the connecting rod 51 fits with the bottom inner wall of the housing 55. The top of the housing 55 is provided with a moving through groove for the connecting rod 51 to move, so as to limit the upper end of the connecting rod 51.
[0072] See also Fig.11 , the installation component 52 includes:
[0073] The base 521 is disposed on the top of the clamping mechanism 3 . A first slide groove 522 is provided on the top of the base 521 . A first slider is placed inside the first slide groove 522 . The top of the first slider is fixedly connected to the bottom of the connecting rod 51 .
[0074] A first mounting plate and a second mounting plate are fixedly provided on the side of the first electromagnet 532 and the second electromagnet 531 that are away from each other, so that the first electromagnet 532 and the second electromagnet 531 are fixedly provided on the side wall of the connecting rod 51 and the inner side wall of the housing 55 through the first mounting plate and the second mounting plate, respectively, and the first mounting plate and the guide rod 533 are fixedly connected on the side that are close to each other, and the pressure sensor 534 is fixedly connected to the side that is close to each other of the first mounting plate, so as to drive the pressure sensor 534 and the guide rod 533 to move with the first electromagnet 532;
[0075] A spring is sleeved on the side wall of the guide rod 533 and located on the side where the pressure sensor 534 and the second mounting plate are close to each other. The force of the roller 56 squeezing the transformer core is monitored by the pressure sensor 534, and the repulsive force generated by the first electromagnet 532 and the second electromagnet 531 is adjusted according to the value of the force. The diameter of the side wall of the pressure sensor 534 is smaller than the inner wall diameter of the first electromagnet 532, and the side walls of the second mounting plate and the shell 55 are provided with through holes for sleeved the guide rod 533.
[0076] In a specific implementation, after adjusting the position of the roller 56 by the clamping mechanism 3, the transformer core that needs to be wound with copper wire is placed between the rollers 56. Since the rollers 56 are arranged in a circular array with the center point of the mounting seat 2, the center point of the transformer core and the center point of the mounting seat 2 are on the same vertical line. Moreover, since the wire-out mechanism 6 passes through the vertical extension line of the center point of the mounting seat 2, the wire-out mechanism 6 usually includes a wire storage ring driven by a motor and a wire-out position arranged on the side wall of the wire storage ring, so that the wire-out position passes through the vertical extension line of the center point of the mounting seat 2, thereby facilitating the copper wire to pass through the center point of the transformer core and be wound on its side wall, thereby reducing the amount of wire used and avoiding the increase in resistance due to the growth of the copper wire, so as to facilitate the production of transformers with specified parameters according to actual production needs.
[0077] After the roller 56 clamps and limits the transformer core, as the copper wire is continuously wound, the roller 56 will gradually move away from the transformer core to ensure that the copper wire has enough winding space, and to ensure that there is enough friction between the roller 56 and the copper wire wound on the transformer core to drive it to rotate continuously, so as to carry out continuous winding. To this end, the first electromagnet 532 and the second electromagnet 531 are started. Since the first electromagnet 532 and the second electromagnet 531 are close to each other on the same magnetic pole, the first electromagnet 532 and the pressure sensor 5 are driven to rotate after power is turned on. 34 moves, thereby driving the connecting rod 51 and the roller 56 to move, so that the roller 56 can move continuously and maintain a certain pressure with the transformer core during the process of the transformer core continuously winding the copper wire, so that while limiting the transformer core, the transformer core can be continuously driven to rotate, and the pressure between the roller 56 and the transformer core is grasped by the value of the pressure sensor 534, so that the pressure information is the same, and the position of the roller 56 is adjusted through the first electromagnet 532, etc., so that the copper wire is always wound around the center point of the transformer core;
[0078] By setting the pressure sensor 534 on the inner wall of the first electromagnet 532, the repulsive force between the first electromagnet 531 is avoided and the actual use of the pressure sensor 534 is facilitated. The movement of the first electromagnet 532 is limited by the guide rod 533, and the stability of the movement of the first electromagnet 532 and the roller 56 is improved. The bottom of the connecting rod 51 is limited by the first slide groove 522 and the first slider of the mounting assembly 52, and the upper end of the connecting rod 51 is limited by the limiting ring 57 and the convexly arranged connecting rod 51, so as to further improve the stability of the movement of the connecting rod 51 and the roller 56.
[0079] The outgoing line mechanism 6 is prior art and will not be described in detail here. The roller 56 is usually an electric roller 56 and is controlled in series so that the rollers 56 arranged in a circular array rotate synchronously to synchronously drive the transformer core to rotate. The above are all prior art and will not be described in detail here.
[0080] See also Fig.13 , the monitoring component 54 includes:
[0081] The detection groove 542 is formed at the top of the guide rod 533, and the inner wall depth of the detection groove 542 gradually increases from the end of the guide rod 533 close to the connecting rod 51 to the end far from the connecting rod 51;
[0082] The distance measuring sensor 541 is fixedly mounted on the outer wall of the housing 55 and is located directly above the detection slot 542 . The distance measuring sensor 541 monitors the distance from the detection slot 542 to monitor the position of the guide rod 533 , thereby determining the position of the roller 56 .
[0083] In specific implementation, since part of the transformer core needs to be wound with copper wire of larger diameter to meet actual use requirements, during the winding process, the copper wire first contacts part of the roller 56, thereby causing the transformer core outlet wire to be offset, so that the copper wire is obliquely wound on the side wall of the transformer core, increasing the amount of wire used and increasing the resistance. For this reason, when the transformer core and the copper wire squeeze the roller 56, the position of the guide rod 533 is monitored by the distance sensor 541, so as to judge the position of the roller 56, so as to adjust the position of the roller 56 in cooperation with the pressure sensor 534, so that the center point of the transformer core is vertically aligned with the center point of the mounting seat 2, so that the copper wire is wound around the center point of the transformer core. In specific operation, since the depth of the detection groove 542 gradually increases from the end of the guide rod 533 close to the connecting rod 51 to the end away from the connecting rod 51, as the position of the guide rod 533 changes, there is a difference in the distance information monitored by the distance sensor 541, so as to judge the position of the guide rod 533 and the roller 56.
[0084] Example 2: Please refer to Figure 5 and Figure 6The difference between this embodiment and the first embodiment is that the clamping mechanism 3 includes a clamping assembly 31 arranged inside the mounting seat 2, a servo motor 32 arranged inside the machine 4 for driving the clamping assembly 31 to operate, and a separation assembly 33 for connecting the servo motor 32 and the clamping assembly 31. The servo motor 32 drives the clamping assembly 31 to operate through the separation assembly 33 to drive the adjustment mechanisms 5 to move closer to or away from each other. The top of the mounting seat 2 is provided with an identification assembly 34 for grasping the position of the adjustment mechanism 5.
[0085] See also Figure 7 , the clamping assembly 31 comprises:
[0086] The second slide groove 312 is opened at the top of the mounting seat 2 in a circular array with the center point of the mounting seat 2, and is located on the outside of the outlet mechanism 6. The inner walls of the second slide grooves 312 on the side close to each other are connected to each other. The second slide grooves 312 are each provided with a second slider. The top of the second slider is fixedly connected to the bottom of the base 521. The side wall of the mounting seat 2 is rotatably provided with threaded rods 311 arranged in a circular array with the center point of the mounting seat 2 and extending into the second slide groove 312 respectively. The threaded rods 311 are threadedly connected with the second slider, and the side walls of the threaded rods 311 on the side close to each other are each fixedly sleeved with a first bevel gear.
[0087] The second bevel gear 313 is lifted and lowered on the output shaft of the servo motor 32 through the splitter assembly 33 and meshes with the first bevel gear.
[0088] During the specific implementation, the servo motor 32 is started, and the output shaft of the servo motor 32 drives the second bevel gear 313 to rotate through the coupling and the separation and combination component 33. The second bevel gear 313 drives the first bevel gear and the threaded rod 311 arranged in a circular array to rotate. Through the meshing of the second bevel gear 313 and the first bevel gear, and the threaded connection direction of the threaded rod 311 and the second slider, the second sliders are synchronously approached or moved away from each other, thereby adjusting the position of the adjustment mechanism 5 and the roller 56. Since the roller 56 is arranged in a circular array with the center point of the mounting seat 2, the movement of the roller 56 is adjusted by linkage, so that the roller 56 is always arranged in a circular array with the center point of the mounting seat 2, which is convenient for clamping and limiting the transformer core. The transformer core is first clamped and limited, and then adjusted by the adjustment mechanism 5. It is suitable for use with transformer cores of different sizes, while reducing the adjustment range of the adjustment mechanism 5 to avoid affecting the adjustment accuracy of the adjustment mechanism 5.
[0089] See also Fig. 9 , the identification component 34 includes:
[0090] The identification block 342 is fixed to the side wall of the base 521;
[0091] The scale plate 341 is fixedly disposed on the top of the mounting base 2 and is located at the bottom of the identification block 342 so that the tip of the identification block 342 points to the scale plate 341 .
[0092] In a specific implementation, when the position of the adjusting mechanism 5 changes with the adjustment of the clamping assembly 31, the base 521 drives the identification block 342 to move, and the identification block 342 points to the position of the scale plate 341, so as to grasp the position of the rollers 56 arranged in a circular array, and facilitate the subsequent adjustment of the position of a single roller 56 through the separation and combination assembly 33.
[0093] See also Figure 7 and Figure 8 , the splitting and combining assembly 33 comprises:
[0094] The mounting ring 331 is fixedly arranged at the bottom of the mounting seat 2, and an adjusting seat 336 is rotatably arranged on the inner wall of the mounting ring 331, a third electromagnet 334 is fixedly arranged on the inner wall at the bottom of the adjusting seat 336, and a fourth electromagnet 335 is sleeved on the inner wall of the adjusting seat 336, and the side where the fourth electromagnet 335 and the third electromagnet 334 are close to each other are the same poles, and a limiting rod 332 is fixedly arranged on the top of the fourth electromagnet 335, and the top of the limiting rod 332 extends to the top of the adjusting seat 336 and is fixedly connected to the bottom of the second bevel gear 313.
[0095] The output shaft of the servo motor 32 is fixedly provided with a rotating shaft through a coupling, and the top of the rotating shaft is fixedly connected to the bottom of the adjustment seat 336;
[0096] The separation and combination assembly 33 also includes:
[0097] The limit blocks 333 are fixed in a circular array on the side wall of the limit rod 332. The top of the side wall of the adjustment seat 336 is provided with limit grooves arranged in a circular array and adapted to the limit blocks 333. The limit blocks 333 move vertically along the limit grooves to limit the lifting and lowering of the limit rod 332.
[0098] A first groove is provided at the top of the adjustment seat 336, and a second groove is provided on the bottom inner wall of the first groove. The third electromagnet 334 and the fourth electromagnet 335 are both located in the second groove, and the side wall of the fourth electromagnet 335 is in contact with the inner wall of the second groove. The limiting groove is connected to the first groove, and the inner wall of the first groove is in contact with the side wall of the limiting rod 332.
[0099] In specific implementation, since the threaded rod 311 will undergo certain wear during long-term use, the positions of the multiple adjustment mechanisms 5 and the roller 56 arranged in a ring array will be out of sync. To this end, the third electromagnet 334 and the fourth electromagnet 335 are powered off so that the second bevel gear 313 can move downward, thereby making the first bevel gear in linkage contact, and one of the threaded rods 311 can be rotated alone, and the adjustment amount can be grasped through the identification component 34, so as to facilitate the subsequent linkage and synchronous driving of the adjustment mechanism 5 to move. When the adjustment is completed, the third electromagnet 334 and the fourth electromagnet 335 are powered on so that the second bevel gear 313 is meshed with the first bevel gear, so as to facilitate the linkage and driving of the threaded rod 311 to rotate. When the second bevel gear 313 is meshed with the first bevel gear, the second bevel gear 313 can be meshed with the first bevel gear first, and then the third electromagnet 334 and the fourth electromagnet 335 are powered on, so as to facilitate the rotation of the second bevel gear 313 and mesh with the first bevel gear.
[0100] The embodiment of the present invention further provides a winding method of a transformer core winding device, using a transformer core winding device, the method comprising the following steps:
[0101] S1: The transformer core that needs to be wound with copper wire is limited by the clamping mechanism 3, so that the roller 56 limits the transformer core and drives the transformer core to rotate at the same time, so that the copper wire is wound on the side wall of the transformer core through the outlet mechanism 6;
[0102] S2: In the process of clamping the transformer core, the clamping assembly 31 and the servo motor 32 of the clamping mechanism 3 synchronously drive the adjustment mechanism 5 and the roller 56 to move, so as to initially position the roller 56, so that the position of the roller 56 is suitable for the size of the transformer core, and because the rollers 56 are arranged in a circular array with the center point of the mounting seat 2, and the outlet position of the outlet mechanism 6 passes through the vertical extension line of the center point of the mounting seat 2, so that the center point of the transformer core and the center point of the mounting seat 2 are located on the same vertical straight line, so that the copper wire passes through the center of the transformer core through the outlet mechanism 6 and is wound on the side wall of the transformer core;
[0103] During long-term use, the position of the adjustment mechanism 5 is grasped by the identification component 34, so that when the multiple threaded rods 311 arranged in the annular array are not synchronized due to mechanical wear of the threaded rods 311, the separation component 33 can be used to rotate and adjust one of the threaded rods 311 separately to adjust the position of the adjustment mechanism 5 at the corresponding position;
[0104] S3: After the clamping is completed, the pressing force of the roller 56 on the transformer core is adjusted by the adjusting component 53 of the adjusting mechanism 5 according to the pressure between the roller 56 and the transformer core, so that during the continuous winding process, the transformer core is continuously limited and the transformer core is driven to rotate, and the center point of the transformer core is vertically aligned with the center point of the mounting seat 2, so as to assist in winding the copper wire;
[0105] Due to the different diameters of the copper wires, some of which are larger in diameter, when winding the copper wire with a larger diameter, some of the rollers 56 arranged in a circular array first contact the wound copper wire, and the remaining rollers 56 contact the transformer core on which the copper wire is not wound, thereby causing a position difference between the rollers 56. For this purpose, the position of the roller 56 is monitored by the monitoring component 54, and the position of the roller 56 is adjusted by combining the position information of the roller 56 and the pressure information between the roller 56 and the transformer core, so that the copper wire can be more accurately wound around the side wall of the transformer core through the midpoint of the transformer core.
