Winding equipment for annular inductor

Abstract

The invention is suitable for the technical field of annular inductor winding, and provides an annular inductor winding device which comprises a machining assembly, a winding assembly is rotationally arranged in the machining assembly, and the machining assembly comprises a mounting part and a guide part fixed to the mounting part. The winding device solves the problems that a winding ring in a winding piece of an existing winding device for the annular inductor is in a closed ring shape, so that the winding ring cannot be wound around the winding piece before winding or after winding is finished, and the winding piece cannot rotate around the winding piece, so that the winding piece cannot rotate around the winding piece, and the winding piece cannot rotate around the winding piece. In the prior art, an annular magnetic core penetrating into a winding ring and a fixed coil barrel need to be repeatedly dismounted and mounted, so that the annular magnetic core and the coil barrel cannot be quickly mounted in the early stage, and meanwhile, the wound annular magnetic core and the coil barrel needing to be replaced cannot be quickly taken out in the later stage. And an early-stage or later-stage operation process is too tedious, so that certain inconvenience is brought to workers.

Description

Technical Field

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. Its structure is similar to that of a transformer. An inductor has a certain inductance, and it only impedes the change of current. An inductor is also called a choke, a reactor, or a dynamic reactor, while a toroidal coil inductor is an electronic component mainly composed of a toroidal magnetic core.

[0044] Example 1, please refer to Figures 1-11 , the present invention provides the following technical solutions:

[0045] A winding device for an annular inductor. Specifically, it includes a processing component 1. Inside the processing component 1, a winding component 2 rotates. The processing component 1 includes a mounting member 3 and a guiding member 4 fixed on the mounting member 3. The winding component 2 includes a winding member 5 rotating on the guiding member 4 and a pin member 6 inserted on the winding member 5. The mounting member 3 includes a mounting plate 301. On the top of the mounting plate 301, a driving H-wheel 302 rotates. On the top of the mounting plate 301, two guiding H-wheels 303 rotate. Between the guiding H-wheels 303 and the driving H-wheel 302, a circular magnetic core 304 rotates. The winding member 5 includes two hinged spool half-rings 501. An accommodation groove 502 is formed on the inner wall of one spool half-ring 501. A U-shaped seat 503 is fixed on the inner wall of the accommodation groove 502. A first circular plate 504 is hinged on the inner wall of the U-shaped seat 503. A spool 505 is fixed at the end of the first circular plate 504. A rectangular hole 506 for inserting the pin member 6 is formed at the end of the spool 505. A side baffle 507 is fixed on the inner wall of the accommodation groove 502 away from the side of the U-shaped seat 503. A U-shaped insertion hole 508 for inserting the pin member 6 is formed at the top of the side baffle 507. A side plate 509 is fixed on the inner wall of one spool half-ring 501 away from the side of the side baffle 507. Two symmetrical guiding crossbars 510 are fixed on the side of the side plate 509. A trapezoidal block 511 slides through between the two guiding crossbars 510. A semi-circular groove 512 for clamping the pin member 6 is formed at the bottom of the trapezoidal block 511. Two first springs 513 respectively sleeved on the two guiding crossbars 510 are fixed between the side plate 509 and the trapezoidal block 511. The pin member 6 includes a rectangular block 601 inserted inside the rectangular hole 506. A second circular plate 602 is fixed at the end of the rectangular block 601. A clamping circular rod 603 for clamping with the U-shaped insertion hole 508 and the semi-circular groove 512 is fixed at the end of the second circular plate 602. The end of the clamping circular rod 603 is provided with a round top.

[0046] The specific application of the first embodiment is as follows: Before the winding operation, the coil tube to be wound is sleeved and rotated to the circumferential side surface of the spool 505 (the coil tube is a hollow circular tube, and magnetic induction lines for subsequent winding operations are wound around its outer surface). After the sleeving is completed, the rectangular block 601 in the pin member 6 is inserted and fitted into the rectangular hole 506 opened at the end of the spool 505. Subsequently, the coil tube sleeved on the circumferential side surface of the spool 505 is pressed, driving the pin member 6 inserted and fitted at the end of the spool 505 to perform a downward pressing action synchronously, so that the round top end of the clamping round rod 603 in the pin member 6 slides on the inclined surface of the trapezoidal block 511, thereby driving the trapezoidal block 511 slidably fitted between the two guiding cross bars 510 to gradually approach the side surface of the side plate 509, and synchronously compressing the first spring 513 connected and fixed between the side plate 509 and the trapezoidal block 511. When the circumferential side surface of the clamping round rod 603 in the pin member 6 is in a fitting state with the inner wall of the U-shaped jack 508, the compressed first spring 513 starts to perform elastic reset, driving the trapezoidal block 511 to slide away from the side plate 509 between the two guiding cross bars 510. At this time, the semi-circular groove 512 opened at the bottom of the trapezoidal block 511 and the U-shaped jack 508 form a complete clamping hole that can position and clamp the clamping round rod 603. During the whole process, the installation steps of the coil tube are simplified, facilitating the subsequent winding steps;

[0047] When the coil tube needs to be replaced, the trapezoidal block 511 is pushed, driving the trapezoidal block 511 slidably fitted between the two guiding cross bars 510 to gradually approach the side surface of the side plate 509, so that the first spring 513 is compressed, driving the semi-circular groove 512 opened at the bottom of the trapezoidal block 511 to gradually separate from the middle circumferential side surface of the clamping round rod 603. Subsequently, the coil tube is lifted, so that the clamping round rod 603 is separated from the U-shaped jack 508. Then, the rectangular block 601 in the pin member 6 is pulled out from the rectangular hole 506, and then the coil tube to be replaced is pulled out from the circumferential side surface of the spool 505, thus completing the disassembly and replacement operation of the coil tube, simplifying the original disassembly method, and bringing certain convenience to the process of disassembling and replacing the coil tube by the staff.

[0049] The specific application of the second embodiment is as follows: Before the winding operation of this winding device, the two spool half-rings 501 in hinge fit are opened in advance, and then the circular magnetic core 304 that needs to be wound is placed between the two spool half-rings 501 in hinge fit. Subsequently, the connecting piece 521 is toggled, so that the side of the connecting piece 521 gradually approaches the round top end of the sliding low rod 516, so that the side of the connecting piece 521 gradually generates a squeezing force on the round top end of the sliding low rod 516, driving the second spring 518 fixedly connected between the second limiting circular plate 517 and the first L-shaped plate 515 to start compressing. Until the second positioning hole 522 formed through the side of the connecting piece 521 and the round top end of the sliding low rod 516 are in a concentric state, the compressed second spring 518 starts to reset. At this time, the round top end of the sliding low rod 516 passes through the second positioning hole 522 and finally inserts into the first positioning hole 519 formed in the side of the other spool half-ring 501, thus completing the loop threading operation of the circular magnetic core 304, simplifying the loop threading process of the circular magnetic core 304 in the whole process, replacing the original loop threading positioning method, and bringing certain convenience to the staff;

[0050] After the ring-shaped magnetic core 304 is threaded and the winding end is positioned, the third limiting circular plate 412 is first pulled, so that the third spring 413 fixedly connected between the third limiting circular plate 412 and the second L-shaped plate 410 is stretched, driving the positioning rod 411 inserted in the plug-in circular hole to slide out of the plug-in circular hole step by step, and then the second L-shaped plate 410 is started to be moved, driving the arc block 406 to slide on the inner wall of the arc groove 405, so that the arc block 406 is gradually The arc block 406 is moved closer to the end of the extension spool plate 403. During the sliding process of the arc block 406 on the inner wall of the arc slot 405, the end of the positioning rod 411 gradually slides out from the inner wall of the groove 415 and finally slides on the outer wall of the arc positioning plate 414 (during the sliding process of the end of the positioning rod 411 from the inner wall of the groove 415 to the outer wall of the arc positioning plate 414, the third spring 413 is continuously stretched until the end of the positioning rod 411 slides and connects to the outer wall of the arc positioning plate 414. When the third spring 413 is stretched, the stretching process of the third spring 413 stops), thereby driving the rotating arm 409 rotating between the first pin shaft column 404 and the second pin shaft column 408 to rotate, and thereby pushing the extended bobbin plate 403 rotating at the end of the arc bobbin frame 402 to expand the opening. After the opening expansion is completed, the two bobbin half rings 501 that are hinged and passed through the annular magnetic core 304 are placed on the two second bearing rollers 419 from the open end of the arc bobbin frame 402 after the opening expansion is completed, so that the transmission grooves 523 opened on the outer walls of the two bobbin half rings 501 are rotatably connected to the side surfaces of the two bearing rollers 419. Subsequently, the annular magnetic core 304 passing through the two bobbin half rings 501 is rotatably connected to the friction belt 312 (the friction belt 312 is made of flexible rubber material) fixed on the inner walls of the active H wheel 302 and the guide H wheel 303, so that the two hinged bobbin half rings 501 and the annular magnetic core 304 are in a mutually perpendicular state (such as Figure 1 As shown in the figure, finally, the second L-shaped plate 410 is reversely pushed to drive the arc block 406 to slide on the inner wall of the arc slot 405, so that the arc block 406 gradually moves away from the end of the extension spool plate 403. During the sliding process of the arc block 406 on the inner wall of the arc slot 405, the rotating arm 409 rotating between the first pin column 404 and the second pin column 408 rotates in the opposite direction again, thereby pulling the extension spool plate 403 rotated by the end of the arc spool frame 402 to close and retract, until the extension spool plate 403 and the extension spool plate 403 are aligned. When the arc-shaped bobbin frame 402 is in a coaxial state, the first bearing roller 418 and the transmission groove 523 that are rotated and matched by the side surface of the first shaft column 416 are in a mutually fitting state. In the process that the end of the positioning rod 411 gradually slides from the outer wall of the arc-shaped positioning plate 414 to the inner wall of the groove 415, combined with the elastic restoring force of the third spring 413, the bottom end of the positioning rod 411 is finally plugged into the plug-in circular hole opened on the inner wall of the groove 415, thereby completing the rotation installation process of the winding member 5 for the subsequent winding operation;

[0051] After all the above operations are completed, the stepper motor 311 and the DC motor 314 are synchronously started through the controller 318, so that the pulley 315 fixed to the output shaft of the DC motor 314 rotates. As the pulley 315 rotates, it synchronously drives the two second bearing rollers 419 and the tensioning roller 421 to transmit power, thereby driving the transmission groove 523 that is in contact with the outer wall of the conveyor belt 316 to perform a circular motion, causing the entire winding assembly 2 to synchronously perform a circular rotation on the first bearing roller 418 and the two second bearing rollers 419 (when the entire winding assembly 2 synchronously performs a circular rotation on the first bearing roller 418 and the two second bearing rollers 419, the number of turns that the winding assembly 2 needs to rotate is calculated through the induction process between the infrared sensor 317 fixed to the top of the transverse plate 305 and the connecting piece 521). During the process in which the entire winding assembly 2 synchronously performs a circular rotation on the first bearing roller 418 and the two second bearing rollers 419, the stepper motor 311 drives the driving H-wheel 302 fixed to its output shaft to rotate, thereby driving the circular magnetic core 304 that is rotationally fitted between the driving H-wheel 302 and the two guiding H-wheels 303 to synchronously perform a slow circumferential rotation (the friction belts 312 fixed to the inner walls of the driving H-wheel 302 and the two guiding H-wheels 303 increase the friction force during the rotation of the circular magnetic core 304 between the driving H-wheel 302 and the two guiding H-wheels 303), thereby completing the winding operation in the whole process.
