Description

Technical Field

[0001] The invention relates to the technical field of winding equipment, in particular to a winding device for mutual inductor production. Background Art

[0002] In the production process of mutual inductors, the core usually needs to be wound with enameled wire to form the coil required for electromagnetic induction. For traditional round cores, due to their regular shape, it is easier to maintain the uniformity and tightness of the coil when winding the enameled wire, thereby ensuring the excellent electrical performance of the mutual inductor. However, with the advancement of technology and the diversification of application requirements, rectangular cores have gradually become the preferred choice for mutual inductors in certain specific occasions due to their special structural advantages.

[0003] The traditional device has the following shortcomings:

[0004] The existing rectangular core faces greater challenges when winding the enameled wire, especially in the processing of the four corners. Due to the lack of suitable driving equipment, the winding work of the rectangular core often relies on manual work with the wire storage rack. The wire storage rack releases the wire, and the staff continues to push the core and rotate it at the corner until the winding is completed. However, this manual pushing method is not only inefficient, but also difficult to ensure the stability and consistency of the coil during the winding process. Especially when dealing with the fillet at the corner of the rectangular core, manual operation can easily cause the coil to tilt, resulting in uneven distribution of the enameled wire at the fillet, and the problem of uneven gap size. This uneven winding will not only increase the use of enameled wire and increase production costs, but more importantly, it will directly affect the electrical performance of the transformer, such as increasing the mutual inductance error and deteriorating the temperature characteristics, thereby reducing the stability and reliability of the transformer in the later application process.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0048] See also Figure 1-14As shown, the present invention provides a technical solution for a winding device for transformer production: a winding device for transformer production, comprising a base 1 and a mounting frame 2 installed on one side of the upper end surface of the base 1, a wire storage ring 3 is installed through one side of the mounting frame 2, and the wire storage ring 3 is placed by setting an opening like a traditional winding machine to place the iron core to be wound, a feed table 4 is horizontally slidably connected to the upper end surface of the base 1 through a transverse groove, a clamping mechanism 5 for positioning the rectangular iron core is installed on the upper end surface of the feed table 4, a rotating mechanism 6 for driving the iron core to rotate and wind is installed on one side of the interior of the base 1, a driving mechanism 7 for driving the wire storage ring 3 and the feed table 4 is installed in the mounting frame 2 and the base 1, and a controller 8 is also installed on the upper end surface of the base 1.

[0049] The rotating mechanism 6 includes a rotating seat 601, a first motor 606 and a driving plate 608. The rotating seat 601 is movably mounted on the upper end surface of the feed table 4. A positioning member 602 is installed at the lower end of the rotating seat 601 for positioning on the feed table 4. The main body of the rotating seat 601 has through holes around which a positioning rod 603 is fixedly installed. The lower end of the positioning rod 603 is slidably connected with a gear rod 604. A rod groove is opened on one side of the table surface of the feed table 4. The size of the rod groove matches the gear rod 604, which facilitates the telescopic movement of the gear rod 604 in the rod groove. The lower end of the positioning rod 603 is a hexagonal sleeve 6031, and the rod wall of the gear rod 604 is also a regular hexagon that matches the hexagonal sleeve 6031, ensuring that the gear rod 604 can drive the positioning rod 603 and the rotating seat 601 to rotate. A magnetic attraction part 605 for controlling the extension and retraction of the gear rod 604 is also installed between the gear rod 604 and the positioning rod 603. The magnetic attraction part 605 is composed of a permanent magnet and an electromagnet. The permanent magnet is arranged in the main body of the gear rod 604, and the electromagnet is arranged on the inner side of the hole below the positioning rod 603 and on the feed table 4 below the gear rod 604. When the gear rod 604 needs to be retracted, the upper electromagnet generates an attractive force on the gear rod 604, and the lower electromagnet generates a repulsive force on the gear rod 604. The clamping mechanism 5 is installed above the positioning rod 603, and the axis of the positioning rod 603 coincides with the center of the four rounded corners of the rectangular iron core. The first motor 606 is horizontally installed in the installation cavity on one side of the interior of the base 1 through a bracket. Figure 4 As shown, the output end of the first motor 606 is connected to a gear set 607. The driving plate 608 is slidably connected in the slide groove on one side of the base 1. The driving plate 608 moves horizontally along the slide groove on one side of the base 1 through the limit groove. One side of the driving plate 608 is meshed with the gear set 607 through the teeth. The other side of the driving plate 608 is located in the notch of the feed table 4 and has teeth matching the gear rod 604 for driving the rotating seat 601 to rotate. Figure 5As shown, on the slide groove wall on one side of the feed table 4, located below the rod groove, a plurality of positioning holes are provided, the diameter of the positioning holes matches the end of the gear rod 604, and the positioning holes are controlled by the spacing to ensure that the end of the gear rod 604 can enter the positioning holes after being inserted into the rod groove, which can effectively avoid horizontal displacement when the rotating seat 601 rotates.

[0050] When the rectangular core is winding the enameled wire, the driving mechanism 7 first drives the rectangular core to move horizontally, and the wire storage ring 3 winds the enameled wire synchronously. Fig.12 As shown, when the enameled wire is wound around the rounded corner of the rectangular core, the controller 8 controls the feed table 4 to stop horizontal movement, and at the same time, the clamping mechanism 5 at the rounded corner is separated from the rectangular core. The magnetic attraction member 605 of the positioning rod 603 at the rounded corner of the rectangular core is controlled by the controller 8 to eject the gear rod 604 downward through the rod groove on the feed table 4 and engage with the teeth on one side of the drive plate 608. Then, the controller 8 controls the first motor 606 to start, driving the drive plate 608 to move horizontally for a certain distance to make the gear rod 604 rotate 90 degrees, as shown in FIG. Fig.13 As shown, at this time, the rotating seat 601 and the rectangular iron core above the rotating seat 601 rotate 90 degrees with the gear rod 604 as the rotation center. During the rotation of the rectangular iron core, since the tangent line at the end of the wire storage ring 3 always coincides with the axis of the positioning rod 603, the wire storage ring 3 is always perpendicular to the outer wall of the iron core, and the enameled wire is always perpendicular to the outer wall of the rectangular iron core during the process of winding the rectangular iron core fillet.

[0051] By means of the rotating mechanism 6, it is achieved that when winding the rounded corners of the rectangular core, the rectangular core is synchronously rotated with the center of the rounded corner as the axis, and finally the enameled wire is vertically and evenly wound on the rounded corners of the rectangular core, avoiding winding tilt, which not only reduces the winding amount of the enameled wire and saves production costs, but also improves the electrical performance of the mutual inductor as well as the stability and reliability in the later application process.

[0052] The driving mechanism 7 includes a screw rod 701, a gear ring 702, a second motor 704 and a transmission 708. The screw rod 701 runs through a groove installed on the base 1, and the feed table 4 is installed on the screw rod 701 and driven by the screw rod 701 to move horizontally. The gear ring 702 is connected to one side of the wire storage ring 3 through a connecting rod, and a transmission gear 703 meshing with the gear ring 702 is embedded in the mounting frame 2. The second motor 704 is installed in the mounting groove at the lower end of the base 1 through a bracket, and the output end of the second motor 704 is connected to a rotating shaft group 705, and a first transmission pulley 706 for driving the wire storage ring 3 to rotate is connected between one side of the rotating shaft group 705 and the axle of the transmission gear 703, and a second transmission pulley 707 for driving the feed table 4 to move horizontally is connected between the other side of the rotating shaft group 705 and the screw rod 701. The transmission 708 is connected between the rotating shaft groups 705. The transmission 708 can be used to adjust the rotation speed of the screw rod 701, that is, the feeding speed of the feed table 4, and then adjust the winding density of the enameled wire on the iron core. At the same time, the transmission 708 can also effectively cut off the power output to the screw rod 701 when the rectangular iron core needs to be wound at a corner, so that the feed table 4 remains stationary.

[0053] When the four sides of the rectangular core need to be wound, the controller 8 is used to set the transmission 708 to adjust the wire output speed of the wire storage ring 3, and then the second motor 704 is started. The second motor 704 drives the screw rod 701 and the wire storage ring 3 to rotate through the first transmission pulley 706 and the second transmission pulley 707, and the rectangular core begins to wind the edges. When the enameled wire is wound around the rounded corner of the rectangular core, the controller 8 controls the transmission 708 to make adjustments, stops the power output to the screw rod 701, and the feed table 4 stops feeding, but keeps the wire output of the wire storage ring 3 at a constant speed until the rectangular core rotates 90 degrees, and the winding of the rounded enameled wire is completed. At this time, the controller 8 will adjust the transmission 708 again to restore the power output to the screw rod 701, and the feed table 4 will resume feeding, and start winding the next side of the rectangular core.

[0054] Through the driving mechanism 7, power output control of the feed table 4 and the wire storage ring 3 is realized when the enameled wire is wound on the rectangular iron core. When winding the rounded corners, only the wire storage ring 3 releases the wire at a uniform speed. When winding the rectangular edges, the feed table 4 and the wire storage ring 3 operate synchronously. The control is flexible and efficient, and the feeding speed of the feed table 4 and the speed ratio of the wire storage ring 3 are adjustable and stable, which ensures the uniform distribution of the enameled wire on the iron core and further improves the winding effect and product quality.

[0055] The clamping mechanism 5 includes a lifting sleeve 501, a sealing slider 504 and a mounting plate 505. The lifting sleeve 501 is slidably connected to the upper end of the positioning rod 603. The positioning rod 603 is provided with an air hole 502. The inner side of the lifting sleeve 501 is fixedly connected with a sliding rod 503. The end of the sliding rod 503 is slidably and sealedly connected to the hole wall of the air hole 502 by installing a Gley sealing ring. The inner wall of the lower end of the positioning rod 603 is smooth except for the inner hexagonal sleeve 6031. The sealing slider 504 is installed on the upper end of the gear rod 604 and is slidably and sealedly connected to the lower inner wall of the positioning rod 603. At this time, a sealed cavity is formed in the positioning rod 603 between the sliding rod 503 and the sealing slider 504. When the sealing slider 504 rises, the sliding rod 503 will drive the lifting sleeve 501 to rise. When the sealing slider 504 falls, the sliding rod 503 will also drive the lifting sleeve 501 to fall synchronously. This movement is also achieved through the cooperation of the magnetic suction member 605. Under normal circumstances, the magnetic attraction member 605 positions the gear rod 604 in the positioning rod 603 by attraction, and the sealing slider 504 is also located at the uppermost end, so the lifting sleeve 501 is also stabilized at the uppermost end of the positioning rod 603 under the action of the air pressure in the sealing chamber. The mounting plate 505 is fixedly mounted on the upper end of the lifting sleeve 501, and two telescopic rods 506 are mounted on the mounting plate 505, the angle between the two telescopic rods 506 is 90 degrees, and the ends of the two telescopic rods 506 are mounted with positioning claws 507 for locking the rectangular iron core.

[0056] When the rectangular core needs to be clamped and positioned, the staff will first manually place the rectangular core outside the positioning claw 507, and then start all the telescopic rods, and all the telescopic rods will push out the positioning claw 507 to position the four corners of the rectangular core. At this time, the edge of the core can be wound with enameled wire. When the infrared sensor senses that the position of the core needs to be wound around the fillet of the core, the sensor sends an electrical signal to the controller 8, and the controller 8 controls the telescopic rod at the fillet to retract the positioning claw 507, and then pushes the gear rod 604 downward by adjusting the current of the electromagnet in the magnetic suction part 605, and the core will rotate with the gear rod 604 as the axis. At this time, due to the descent of the sealing slider 504, the lifting sleeve 501 also drives the positioning claw 507 to descend synchronously under the action of air pressure, so as to avoid interference between the wire storage ring 3 and the positioning claw 507 when the core rotates around the fillet. At this time, only three corners of the rectangular core are positioned, but the stability of the enameled wire winding can still be met. When the fillet is wound, the controller 8 adjusts the current of the electromagnet in the magnetic attraction part 605 again, so that the gear rod 604 is retracted into the positioning rod 603. At this time, the sealing slider 504 rises, and the lifting sleeve 501 is reset under the action of air pressure. Finally, the positioning claw 507 is extended to reposition the fillet of the iron core.

[0057] Through the clamping mechanism 5, the positioning and clamping of the rectangular iron core when the enameled wire is wound is achieved. Through the linkage with the lifting and lowering of the toothed rod 604, the clamping piece and the lifting sleeve 501 at the rounded corner can be synchronously lowered with the toothed rod 604 when winding the iron core rounded corner, so as to avoid interference with the wire storage ring 3 during rotation. After the rotation is completed, the clamping piece and the lifting sleeve 501 will rise and reset synchronously with the toothed rod 604. The design is ingenious, which not only meets the clamping and positioning requirements of the iron core, but also ensures the movement effect when the iron core is wound around the rounded corner.

[0058] The positioning member 602 includes an electromagnetic disk 6021, which is slidably connected to the mounting groove at the lower end of the rotating seat 601. A reset spring 6022 is connected between the electromagnetic disk 6021 and the rotating seat 601. When the rectangular core moves horizontally with the feed table 4, the controller 8 controls the electromagnetic disk 6021 to be powered on and attracted to the feed table 4. At this time, the rotating seat 601 is fixed on the feed table 4. When the rotating seat 601 and the rectangular core need to be rotated, the electromagnetic disk 6021 is powered off, and the electromagnetic disk 6021 is reset under the action of the reset spring 6022.

[0059] A number of telescopic balls 6023 for reducing sliding friction are installed on the lower end surface of the rotating seat 601. The telescopic balls 6023 can ensure the stability of the rotating seat 601 when it rotates on the surface of the feed table 4, and the diameter of the telescopic balls 6023 should be larger than the rod groove on the surface of the feed table 4 to prevent the telescopic balls 6023 from getting stuck in the rod groove during movement.

[0060] An auxiliary support frame 9 for supporting the wire storage ring 3 is installed on the upper end surface of the base 1. The auxiliary support frame 9 can improve the stability of the wire storage ring 3 during operation.

[0061] The length between the driving plate 608 and the feeding platform 4 is greater than the circumference of the rectangular core.

[0062] The transmission 708 is a clutch transmission, which can cut off the power output to the lead screw 701 when the enameled wire is wound around the rounded corners of the rectangular core.

[0063] Working principle: When the rectangular core needs to be wound with enameled wire, the staff will first manually place the rectangular core outside the positioning claw 507, and then start all the telescopic rods, which will push the positioning claw 507 out to position the four corners of the rectangular core. At this time, the transmission 708 is set by the controller 8, and the outlet speed of the wire storage ring 3 is adjusted. Then the second motor 704 is started, and the second motor 704 drives the screw rod 701 and the wire storage ring 3 to rotate through the first transmission pulley 706 and the second transmission pulley 707 respectively. At this time, the rectangular core begins to be wound.

[0064] When the infrared sensor senses that the position of the iron core needs to be wound around the fillet of the iron core, the sensor sends an electrical signal to the controller 8, and the controller 8 controls the transmission 708 to make adjustments, stops the power output to the screw 701, and the feed table 4 stops feeding. At the same time, the controller 8 controls the telescopic rod at the fillet to retract the positioning claw 507, and then pushes the gear rod 604 downward by adjusting the current of the electromagnet in the magnetic suction part 605, and engages with the teeth of the drive plate 608. At this time, due to the descent of the sealing slider 504, the lifting sleeve 501 also drives the positioning claw 507 to descend synchronously under the action of air pressure. Then the controller 8 controls the first motor 606 to start, driving the drive plate 608 to move horizontally a certain distance to drive the gear rod 604 to rotate 90 degrees, and the wire storage ring 3 outputs the wire synchronously, and the enameled wire winding of the fillet is completed. At this time, the controller 8 will adjust the transmission 708 again to restore the power output of the screw rod 701, and the feed table 4 will resume feeding. At the same time, the gear rod 604 on this side will be recovered, and the rounded corner of the rectangular core will also resume the clamping position, so that the next side of the rectangular core can be wound.
