Description

Technical Field

[0001] The invention relates to the field of electronic processing and manufacturing, and in particular to a winding device for processing chip-type inductors. Background Art

[0002] The winding device for chip inductor processing is a device used to produce chip inductors. It is mainly used to wind copper or aluminum wire around the inductor core to form an inductor coil. The inductor core can be set into different shapes. The core of the chip inductor has packaging sheets at both ends for easy installation on the circuit board. The middle core is cylindrical in shape. The core material includes ferrite, nickel-zinc ferrite or magnetic ceramics, and the shell is mostly plastic or ceramic packaging.

[0003] The existing Chinese patent with publication number CN212136250U discloses an automatic winding device for a patch-type three-pin inductor. First, a clamping device that can clamp an I-shaped magnetic core and can rotate is placed on one side to clamp the inductor, and the copper wire is passed through the wire-passing shaft and out of the wire-passing part. Next, a driving device drives the carrying box and then drives the wire-passing part close to the inductor. Moreover, due to the eccentric connection of the wire-passing part, when the third driving device rotates, the wire-passing part rotates around the outer periphery of the magnetic core. During the rotation, the second driving device drives the wire-passing part away from the inductor, so that the copper wire is wound around the outer periphery of the magnetic core in the axial direction to form a winding on the inductor. Finally, after winding a coil, the wire-passing part stops rotating first, and the second driving device drives the wire-passing part to move downward so that the copper wire passes through the wire-releasing cavity of the inductor. Finally, the winding is repeated once to wind two windings. At this time, the clamping device rotates to move the inductor of the adjacent workstation for processing, which facilitates the production of inductors with two windings and improves production efficiency.

[0004] However, the automatic winding device for the chip-type three-pin inductor still has the following defects:

[0005] 1. The adaptability of the coil is insufficient. There are many traditional winding methods, but they all involve winding the coil first and then removing it, and then manually assembling the coil and the magnetic core. However, the coils wound by different winding molds have different shapes and sizes, and the size, height and diameter of the magnetic cores on circuit boards of different sizes are inconsistent. The processing efficiency of chip inductors is low and manual intervention is required. It is difficult to achieve multi-station synchronous winding, and the step of manually installing the coil and the magnetic core is added.

[0006] 2. After winding is completed, the wire needs to be cut and the cut must be smooth. Manual cutting of the wire is risky and burrs are easily generated on the cut. In addition, the coil pretreatment steps are not complete, the metal wire is not uniform and not fully prepared, and the unstable winding tension can easily lead to loose or overlapping coils, affecting the inductance performance.

[0007] 3. In addition, the traditional fixing method of the chip inductor during the winding process is not stable enough and will block the surface of the magnetic core. Summary of the Invention

[0030] The present invention provides a winding device for processing chip inductors through improvements, which has the following improvements and advantages compared with the prior art:

[0031] First, the multi-station winding structure is used to wind the magnetic core structure, which is convenient for improving the integrity of the chip inductor. The device can directly wind the wire on the outside of the magnetic core, making the coil more closely fit the magnetic core. It can also be wound according to the shape of the magnetic core, which is convenient for the device to improve the adaptability of the coil. The device can realize multi-station synchronous winding, and adds the steps of manually installing the coil and the magnetic core, which can process multiple groups of chip inductors at the same time.

[0032] The working principle of the multi-station winding structure is to start the servo motor to drive the second supporting base plate to rotate, thereby adjusting the orientation between the winder and the magnetic core structure to facilitate winding of multiple sets of magnetic core structures. In addition, the transmission motor is started to drive the magnetic slider to rotate, and the magnetic slider drives the transmission gear rod to rotate through meshing transmission, and the transmission gear rod drives the winder to rotate. When in use, the metal wire is wound around the two ends of the winder, and the tail end of the metal wire is pulled to the surface of the magnetic core rod, and then the transmission motor is started to drive the winder to rotate to wind the magnetic core rod; in addition, multiple sets of magnetic slide rails are provided inside the movable drum, and a magnetic slider is installed on the side of the inductor fixed structure close to the magnetic slide rail. The inductor fixed structure and the magnetic core structure are slidably connected and disassembled through the magnetic slider and the magnetic slide rail, so that the appropriate number of inductor fixed structures and magnetic core structures can be installed according to production requirements.

[0033] Secondly, the deburring structure removes burrs from the metal wire made of copper or aluminum, and the guide ramp and the second limiting slide bar in the conveyor belt correct the metal wire, flatten and squeeze the metal wire, and pre-stretch the metal wire to improve the uniformity of the metal wire and make the metal wire fully prepared, so that the winding tension is more stable, and the coil is prevented from being loose or overlapping, which affects the inductance performance. After the winding is completed, the wire is cut by the upper and lower sets of extrusion plates to ensure that the incision is smooth and avoid burrs on the incision. This step also facilitates the subsequent multi-station winding structure to wind the metal wire on the surface of the magnetic core structure;

[0034] The working principle of the deburring structure is to first wind the metal wire around the wire winding wheel, and pass the metal wire through the gap between the first friction roller and the second friction roller through the material guide inclined plate, wherein the first friction roller pushes the first supporting bottom plate downward through the elastic element at the top, thereby increasing the crushing pressure between the second friction roller and the first friction roller on the metal wire, and the friction between the rollers can preliminarily remove the protrusions and burrs on the metal, and further start the second telescopic motor to push the movable pressing plate to move. The upper and lower two groups of first limit slides on the movable pressing plate are inclined. When the movable pressing plate moves, it can drive the extrusion plate on one side of the limit slider to move along the path of the first limit slide. The upper and lower two groups The extrusion plate moves toward the direction of the metal wire, thereby squeezing and scratching the burrs on the surface of the metal wire, and finally the metal wire is passed through the second limit slide bar, and the first motor is started to drive the supporting roller to rotate. The rotation direction of the supporting roller is opposite to the movement direction of the metal wire, thereby enhancing the grinding effect of the supporting roller, and then the first telescopic motor is started to drive the movable pressure wheel to press down, and the distance between the movable pressure wheel and the supporting roller becomes closer, increasing the extrusion force on the metal wire, and then the second motor is started to drive the first transmission gear to rotate, and the first transmission gear drives the second limit slide bar to move back and forth through meshing, thereby rubbing the surface of the metal wire and removing debris on the surface of the metal wire that exceeds the internal aperture of the second limit slide bar.

[0035] Thirdly, the magnetic core structure is automatically fixed by the inductor fixing structure, thereby fixing the magnetic core structure to the inner side of the multi-station winding structure. This structure can fix the magnetic core structure without blocking the magnetic core structure, and the fixing effect is stable, and loading and unloading are convenient;

[0036] The working principle of the inductor fixing structure is to first place the magnetic core structure on the top of the workpiece fixing base. The square bottom plate is assembled by the square bottom plate, the magnetic core rod and the square top plate. The bottom end of the magnetic core rod is provided with an inwardly protruding fixed clamping ring. Under normal conditions, the elasticity of the reset metal ring will support the movable slider. The movable slider will be lifted up and the special-shaped pressure plates on both sides will be lifted up. The top of the fixed clamping ring is placed on the bottom end of the protrusions at both ends of the special-shaped pressure plate, and then the special-shaped insertion rod is pushed forward by starting the third motor. The special-shaped insertion rod is pushed toward the top to support the movable slide rod. The movable slide rod can be supported because the bottom end of the special-shaped through-slot is provided with an arc, and the groove at the bottom end of the special-shaped insertion rod also has an arc. Therefore, when the third motor pushes the special-shaped insertion rod forward, the special-shaped insertion rod will drive the movable slide bar to press down, so that the special-shaped pressure plates on both sides press the top of the fixed clamping ring, thereby fixing the magnetic core structure, and connecting the special-shaped pressure plate and the movable slider through the first fixed block. When the movable slide bar moves up, it will drive the movable slider and the special-shaped pressure plates connected on both sides to move up, and the positioning slider slides in the arc-shaped through-groove, which is used to limit the movement trajectory of the top of the special-shaped pressure plate, so that starting the third motor can drive the special-shaped pressure plate to move up and down, thereby playing the role of automatic loading and unloading, installing the empty magnetic core structure, and conveniently removing the magnetic core structure after the winding of the multi-station winding structure is completed.

The magnetic slider 304 is installed on the side of the inductor fixing structure 4 close to the magnetic slide rail 303. The inductor fixing structure 4 and the magnetic core structure 5 are slidably connected and disassembled by the magnetic slider 304 and the magnetic slide rail 303, so that the appropriate number of inductor fixing structures 4 and magnetic core structures 5 can be installed according to production requirements.

[0077] The side of the movable roller 302 away from the deburring structure 2 is connected to the servo motor 308.

[0078] Among them, the output end of the transmission motor 310 is equipped with a transmission gear rod 305. When the transmission motor 310 is started, the magnetic slider 304 is driven to rotate. The magnetic slider 304 drives the transmission gear rod 305 to rotate through meshing transmission. The top of the second support base plate 307 is hingedly connected to the side of the transmission gear rod 305 close to the transmission gear rod 306, and the transmission gear rod 305 and the second transmission gear 306 are meshingly driven. A winder 309 is installed on the side of the second transmission gear 306 away from the second support base plate 307. The transmission gear rod 305 drives the winder 309 to rotate. When in use, the metal wire 6 is wound around the two ends of the winder 309, and the tail end of the metal wire 6 is pulled to the surface of the magnetic core rod 502. Then, the transmission motor 310 is started to drive the winder 309 to rotate, thereby winding the magnetic core rod 502.

[0079] Among them, the inductor fixing structure 4 includes a workpiece fixing base 401, a special-shaped pressure plate 412 and an articulated transmission assembly. A third motor 402 is installed on one side of the workpiece fixing base 401, and the third motor 402 drives the special-shaped pressure plate 412 to open and close through the articulated transmission assembly, thereby installing and removing the magnetic core structure 5; the magnetic core structure 5 is automatically fixed by the inductor fixing structure 4, thereby fixing the magnetic core structure 5 to the inner side of the multi-station winding structure 3. This structure can fix the magnetic core structure 5 without blocking the magnetic core structure 5, and the fixing effect is stable, and loading and unloading and disassembly are convenient;

[0080] The output end of the third motor 402 is equipped with a special-shaped plug 403, and then the special-shaped plug 403 is pushed forward by starting the third motor 402.

[0081] Among them, a movable slide bar 405 is installed at the middle position of the inner part of the workpiece fixing base 401, and the special-shaped inserting rod 403 is pushed toward the top to support the movable slide bar 405, which can support the movable slide bar 405, and a movable slider 406 is sleeved on the outer side of the movable slide bar 405. When the movable slide bar 405 moves up, it will drive the movable slider 406 and the special-shaped pressing plates 412 connected on both sides to move up. A reset metal ring 407 is sleeved at the connection between the movable slider 406 and the movable slide bar 405. Under normal conditions, the elasticity of the reset metal ring 407 will support the movable slide bar 406, and the reset metal ring 407 is elastic.

[0082] Among them, first fixed blocks 409 are installed on both sides of the bottom end of the movable slider 406, and the special-shaped pressure plate 412 and the movable slider 406 are connected through the first fixed block 409, and the first fixed block 409 is connected to the special-shaped pressure plate 412 on the side away from the movable slider 406. When the movable slider 406 is supported, it will drive the special-shaped pressure plates 412 on both sides to lift, and the top of the fixing clamp 504 is placed on the bottom end of the protrusions at both ends of the special-shaped pressure plate 412. The top of the special-shaped pressure plate 412 is penetrated by an arc-shaped through-groove 413, and second fixed blocks 410 are installed on both sides of the top end of the workpiece fixing base 401, and a positioning slider 408 is fixed on the side of the second fixed block 410 close to the movable slide rod 405. The positioning slider 408 is slidably connected inside the arc-shaped through-groove 413, and the positioning slider 408 slides in the arc-shaped through-groove 413 to limit the movement trajectory of the top end of the special-shaped pressure plate 412;

[0083] A second limiting slot 404 is embedded in the end of the workpiece fixing base 401 away from the third motor 402.

[0084] The bottom end of the movable slide bar 405 is inlaid with a special-shaped through-groove 411, and the special-shaped insertion rod 403 passes through the special-shaped through-groove 411 and the second limiting slide groove 404. The diameters on both sides of the special-shaped through-groove 411 are different. The diameter of the side of the special-shaped through-groove 411 close to the third motor 402 is larger than the diameter of the side of the special-shaped through-groove 411 close to the second limiting slide groove 404. The middle part of the special-shaped insertion rod 403 is inlaid with a groove that fits the shape of the bottom end of the special-shaped through-groove 411. Because the bottom end of the special-shaped through-groove 411 is provided with an arc, and the groove at the bottom end of the special-shaped insertion rod 403 is also curved, when the third motor 402 pushes the special-shaped insertion rod 403 forward, the special-shaped insertion rod 403 will drive the movable slide bar 405 to press down, so that the special-shaped pressure plates 412 on both sides press the top of the fixing clamping ring 504, thereby fixing the magnetic core structure 5.

[0085] Starting the third motor 402 can drive the special-shaped pressing plate 412 to move up and down, thereby automatically loading and unloading materials, installing the empty magnetic core structure 5, and conveniently removing the magnetic core structure 5 after the multi-station winding structure 3 is wound.

[0086] Working principle: First, the servo motor 308 is started to drive the second supporting base plate 307 to rotate, thereby adjusting the direction between the winder 309 and the magnetic core structure 5, so as to facilitate the winding of multiple sets of magnetic core structures 5. In addition, the transmission motor 310 is started to drive the magnetic slider 304 to rotate, and the magnetic slider 304 drives the transmission gear rod 305 to rotate through the meshing transmission, and the transmission gear rod 305 drives the winder 309 to rotate. When in use, the metal wire 6 is wound around the two ends of the winder 309, and the tail end of the metal wire 6 is pulled to The surface of the magnetic core rod 502 is then driven by the starting transmission motor 310 to drive the winder 309 to rotate so as to wind the magnetic core rod 502; in addition, a plurality of sets of magnetic slide rails 303 are provided inside the movable roller 302, and a magnetic slider 304 is installed on the side of the inductor fixed structure 4 close to the magnetic slide rail 303, and the inductor fixed structure 4 and the magnetic core structure 5 are slidably connected and disassembled through the magnetic slider 304 and the magnetic slide rail 303, so that the appropriate number of inductor fixed structures 4 and magnetic core structures 5 can be installed according to production requirements.

[0087] Then, the metal wire 6 is first wound around the metal wire winding wheel 201, and the metal wire 6 is passed through the gap between the first friction roller 209 and the second friction roller 210 through the feed inclined plate 203, wherein the first friction roller 209 pushes the first supporting bottom plate 208 downward through the elastic element 207 at the top, thereby increasing the crushing pressure between the second friction roller 210 and the first friction roller 209 on the metal wire 6, and the friction between the rollers can preliminarily remove the bumps and burrs on the metal, and further start the second telescopic motor 215 to push the movable pressing plate 216 to move. The upper and lower sets of first limiting slide grooves 218 of the movable pressing plate 216 are inclined. When the movable pressing plate 216 moves, it can drive the extrusion plate 217 on one side of the limiting slider 219 to move along the path of the first limiting slide groove 218, and the upper and lower sets of extrusion plates 217 moves in the direction of the metal wire 6, thereby squeezing and scratching the burrs on the surface of the metal wire 6, and finally passing the metal wire 6 through the second limiting slide bar 222, starting the first motor 211 to drive the supporting roller 212 to rotate, and the rotation direction of the supporting roller 212 is opposite to the movement direction of the metal wire 6, thereby enhancing the grinding effect of the supporting roller 212, and then starting the first telescopic motor 213 to drive the movable pressure wheel 214 to press down, and the distance between the movable pressure wheel 214 and the supporting roller 212 becomes closer, increasing the extrusion force on the metal wire 6, and then starting the second motor 220 to drive the first transmission gear 221 to rotate, and the first transmission gear 221 drives the second limiting slide bar 222 to move back and forth through meshing, thereby rubbing the surface of the metal wire 6, and removing the debris on the surface of the metal wire 6 that exceeds the internal aperture of the second limiting slide bar 222.

[0088] Finally, the magnetic core structure 5 is placed on the top of the workpiece fixing base 401. The square bottom plate 501 is assembled through the square bottom plate 501, the magnetic core rod 502 and the square top plate 503. The bottom end of the magnetic core rod 502 is provided with a fixed clamping ring 504 protruding inward. Under normal conditions, the elasticity of the reset metal ring 407 will support the movable slider 406. The movable slider 406 will be lifted up to drive the special-shaped pressure plates 412 on both sides to rise, and the top of the fixed clamping ring 504 is placed on the bottom end of the protrusions at both ends of the special-shaped pressure plate 412. Then, the special-shaped insertion rod 403 is pushed forward by starting the third motor 402. The special-shaped insertion rod 403 is pushed toward the top to support the movable slide rod 405. The movable slide rod 405 can be supported because the bottom end of the special-shaped through-groove 411 is provided with an arc, and the groove at the bottom end of the special-shaped insertion rod 403 also has an arc. Therefore, when the third motor 402 pushes the special-shaped insertion rod 403 forward, the special-shaped insertion rod 403 will drive the movable slide bar 405 to press down, so that the special-shaped pressure plates 412 on both sides press the top of the fixed clamping ring 504, thereby fixing the magnetic core structure 5, and connecting the special-shaped pressure plate 412 and the movable slide bar 406 through the first fixed block 409. When the movable slide bar 405 moves up, it will drive the movable slide bar 406 and the special-shaped pressure plates 412 connected on both sides to move up, and the positioning slide bar 408 slides in the arc-shaped through-groove 413, which is used to limit the movement trajectory of the top of the special-shaped pressure plate 412, so that starting the third motor 402 can drive the special-shaped pressure plate 412 to move up and down, thereby playing the role of automatic loading and unloading, installing the empty magnetic core structure 5, and conveniently disassembling the magnetic core structure 5 after the winding of the multi-station winding structure 3 is completed.
