Description

Technical Field

[0001] The present invention relates to the technical field of coil winding, and in particular to a transformer winding coil winding device and a winding method. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). In order to generate a magnetic field when current passes through and induce an electromotive force in the coil when the magnetic field changes, it is necessary to wind a wire into a coil. Only by winding the coil can sufficient magnetic flux and induced electromotive force be formed to achieve the transfer of electrical energy from the primary winding to the secondary winding and voltage transformation.

[0003] At present, as a core power equipment, the performance of a transformer directly affects the stability and energy efficiency of the power grid.

[0015] A method for winding a transformer winding coil provided by the present invention includes the following steps: T1: Start the third hydraulic cylinder, push the sliding plate backward to make the convex block away from the rectangular groove, fold the hinge box in the direction of the second hinge plate to make the clamping rod extend into the positioning shaft, then start the first hydraulic cylinder to make the second hinge plate tilt away from the sliding plate to make one end of the positioning shaft tilt up, turn off the first hydraulic cylinder, and sleeved the spool on the positioning shaft; T2: Start the first hydraulic cylinder to return the second hinge plate to its original position, then start the third hydraulic cylinder to move the sliding plate towards the second hinge plate to make the convex block insert into the rectangular groove, turn the handle to rotate the second screw rod, the second screw rod drives the hinge seat to move towards the movable ring, the hinge seat drives the second clamping plate to move towards the inner wall of the spool and contact and clamp through the hinge rod.

The positioning plug board can also accurately fix the position of the wire, making the distribution of the winding more uniform and regular, helping to optimize the magnetic field distribution inside the transformer and reducing magnetic field distortion; Through the cooperation of the second spring, sliding frame, second hydraulic cylinder, fourth motor, grooved pulley, rotating rod, U-shaped frame and guide bolt, the grooves on the grooved pulley are adapted to the wires. When rotating, the wires can be accurately arranged, avoiding large gaps between the wires, making the winding more compact and neat, so as to make full use of the spool space. More wires can be wound under the same spool size, and the neatly arranged winding can make the insulating material play a better role, reducing the problem of local electric field concentration caused by uneven gaps between the wires, thereby enhancing the overall insulation performance.

When the lifting plate 37 descends to a certain height, the cleaning cotton 45 contacts the outer wall of the wire spool 9. During winding, the dust and impurities on the outer wall of the wire are first cleaned by the soft brush 31. When passing through the second wire arranging ring 35, a large amount of dust and impurities will be slightly scraped off by the scraping ring 41. And when the second annular plate 33 moves towards the second fixed plate 15, the two cleaning cottons 45 can clean the wound wire and the wire spool 9 respectively. Through the setting of the above components of the present invention, the soft brush 31, the cleaning cotton 45 and the scraping ring 41 can remove dust, oil and other impurities on the surfaces of the wire and the wire spool, reduce the wear on the winding device, prevent impurities from entering the transmission components of the equipment or affecting the accuracy of the equipment, and prevent them from mixing into the winding, thus causing problems such as a decrease in insulation performance and short circuit. Secondly, cleaning the wire can improve the quality and reliability of the transformer winding coil. The soft brush 31, the cleaning cotton 45 and the scraping ring 41 can also clean the wire and the wire spool in time during the coil winding process, without the need for the operator to frequently stop the machine for manual cleaning, reducing the downtime and improving the production efficiency. They can be closely attached to the wire and the wire spool, so as to ensure that the cleaning components are in full contact with the surface to be cleaned, more effectively remove the dust, oil and impurities on the surface, and make the cleaning force evenly distributed on the surfaces of the wire and the wire spool, avoiding the situation of incomplete local cleaning or over-cleaning, so as to ensure the consistency of the cleanliness of the entire winding coil. Secondly, by adjusting the pressure and adaptability of the cleaning cotton 45, the wire spools of different lengths can be cleaned, enhancing the versatility and flexibility of the cleaning device.

[0032] Third Embodiment: Based on the transformer winding coil winding device provided in the second embodiment of the present application, the third embodiment of the present application proposes another transformer winding coil winding device. The third embodiment is only a preferred way of the second embodiment, and the implementation of the third embodiment will not affect the independent implementation of the second embodiment.

[0033] The following further describes the third embodiment of the present invention in conjunction with the drawings and the embodiments.

[0034] Please refer to Figures 12 - 16, the transformer winding coil winding device further includes a detachable plate 57. The detachable plate 57 is fixedly installed on one side of the second hinge plate 6 close to the second annular plate 33. The detachable plate 57 can be replaced according to the length of the spool 9, so as to facilitate multiple positioning inserts 58 to be inserted into the gaps between wires. A plurality of positioning inserts 58 are provided on the top of the detachable plate 57. Connecting rods 59 are fixedly installed at the bottoms of the plurality of positioning inserts 58. The bottom ends of the connecting rods 59 penetrate through the detachable plate 57 and are rotatably installed with rollers 61. A third spring 60 is sleeved on the outer side of the connecting rod 59. The two ends of the third spring 60 are fixedly connected to the detachable plate 57 and the connecting rod 59 respectively. A wedge-shaped plate 46 is fixedly installed on one side of the first annular plate 32 close to the second hinge plate 6. One end of the wedge-shaped plate 46 penetrates through the first hinge plate 2. A guide bolt 50 is fixedly installed on one side of the second annular plate 33 close to the first annular plate 32. A sliding frame 51 is slidably installed on the guide bolt 50. A U-shaped frame 56 is provided on one side of the sliding frame 51 close to the spool 9. A rotating rod 55 is rotatably installed on the U-shaped frame 56. A grooved wheel 54 is fixedly installed on the outer wall of the rotating rod 55. A fourth motor 48 is fixedly installed on the top of the U-shaped frame 56. The output shaft of the fourth motor 48 is fixedly connected to the rotating rod 55. A second hydraulic cylinder 53 is fixedly installed on the other side of the sliding frame 51. The output shaft of the second hydraulic cylinder 53 is fixedly connected to the U-shaped frame 56. The same second spring 49 is sleeved on the outer side of the guide bolt 50. The two ends of the second spring 49 are fixedly connected to the first annular plate 32 and the sliding frame 51 respectively. A visual detection device is further provided on one side of the second hinge plate 6 close to the spool 9. When winding the wire, the fifth motor 52 drives the reciprocating lead screw 47 to rotate through the output shaft, so that the sliding seat 7 moves away from the fifth motor 52. When the sliding seat 7 moves to the end of the first guide rod 4, the wire will be completely wound on the spool 9. Since the wire will vibrate during winding, at this time, the pitch between turns of the wire on the spool 9 will be too large. In order to prevent the distance between wire turns from becoming larger and larger due to the continuous movement of the sliding seat 7, resulting in the wire not being able to be completely wound on the spool 9, at this time, an external visual detection device is used to detect the distance between wire turns. When the distance is too large, the fifth motor 52 is controlled to reduce the speed, so that the winding speed becomes slower.

[0035] The two grooved wheels 54 are respectively arranged on both sides of the spool 9.

[0036] The top of the wedge-shaped plate 46 is provided with an inclined surface. The plurality of rollers 61 are all in contact with the top of the wedge-shaped plate 46. Through the inclined surface, the plurality of rollers 61 can drive the plurality of positioning inserts 58 to move up and down.

[0037] During winding, the fifth motor 52 is started. The output shaft of the fifth motor 52 drives the reciprocating lead screw 47 to rotate, causing the sliding seat 7 to reciprocate, so as to neatly wind the wire around the spool 9. And when the second annular plate 33 moves towards the second fixed plate 15, the sliding frame 51 can be driven to move through the guiding bolt 50. The second hydraulic cylinder 53 is started, and the telescopic end of the second hydraulic cylinder 53 drives the U-shaped frame 56 to move towards the spool 9, so that the groove on the grooved pulley 54 contacts the outer wall of the wire. The fourth motor 48 is started, and the output shaft of the fourth motor 48 drives the rotating rod 55 to rotate, thereby driving the grooved pulley 54 to rotate, arranging the wires to prevent large gaps between the wires. And when the first annular plate 32 moves towards the second fixed plate 15, it will drive the wedge plate 46 to move towards the second fixed plate 15 and drive the positioning plug 58 to lift, so that a plurality of positioning plugs 58 are respectively inserted into the gaps between the wires, thereby fixing the positions of the wires. When the first annular plate 32 moves towards the second hinge plate 6, the positioning plug 58 will descend along the inclined surface and move away from the gaps on the wire. A visual detection device is also provided on one side of the second hinge plate 6 close to the spool 9. During wire winding, the fifth motor 52 drives the reciprocating lead screw 47 to rotate through the output shaft, causing the sliding seat 7 to move away from the fifth motor 52. When the sliding seat 7 moves to the end of the first guide rod 4, the wire will be completely wound around the spool 9. Since the wire will vibrate during winding, at this time, the turn pitch on the spool 9 will be too large. In order to prevent the distance between turns from becoming larger and larger due to the continuous movement of the sliding seat 7, resulting in the inability to completely wind the wire around the spool 9, an external visual detection device can be used to detect the distance between wire turns. When the distance is too large, the fifth motor 52 is controlled to reduce the speed, so that the winding speed becomes slower. Through the setting of the above components in the present invention, when the positioning plug 58 is inserted into the gap between the wires, the position of each wire can be accurately defined, preventing it from shifting during the winding process, ensuring the accuracy of the number of turns and the spacing of the winding, increasing the stability of the wire, effectively resisting the pulling force and vibration during the winding process, avoiding the loosening or deformation of the wire, ensuring the stability of the winding structure. The positioning plug 58 can also accurately fix the position of the wire, making the distribution of the winding more uniform and regular, helping to optimize the magnetic field distribution inside the transformer, reducing magnetic field distortion. The groove on the grooved pulley 54 is adapted to the wire, and when rotating, it can accurately arrange the wire, avoiding large gaps between the wires, making the winding more compact and neat, so as to make full use of the spool space and wind more wires under the same spool size. And the neatly arranged winding can make the insulating material play a better role, reducing the problem of local electric field concentration caused by uneven gaps between the wires, thereby enhancing the overall insulation performance.

[0038] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present invention.
