Description

Technical Field

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

[0002] A coil is an electronic component made of an insulated wire (such as enameled wire) tightly wound into a spiral or ring shape. Its core function is to store magnetic energy. When current passes through the coil, a magnetic field is generated. The changing magnetic field can induce voltage in the coil. This characteristic is called electromagnetic induction. The coil is the core component of an inductor and a transformer, and energy storage, transfer and circuit regulation are achieved through electromagnetic induction.

[0003] In the prior art, for example, Chinese patent number: CN117423544B discloses a coil winding device for transformer and inductor windings, including a base, and also including a wire feeding assembly, a coil winding assembly and a single-side fixing assembly installed on the base, the iron core is installed on the coil winding assembly, the wire feeding assembly can be raised and lowered to feed the copper wire, so that the copper wire can be reciprocated up and down on the iron core for coil winding, and the single-side fixing assembly fixes the outer ring of the coil, the action assembly is installed in the base, and can be linked to complete the action of the wire feeding assembly, the coil winding assembly and the single-side fixing assembly. The present invention discloses a coil winding device for transformer and inductor windings, the copper wire passes through the wire feeding assembly and is wound on the iron core, after the coil winding assembly rotates, the copper wire is wound on the iron core, the wire feeding assembly can be raised and lowered to feed the copper wire, so that the copper wire can be reciprocated up and down on the iron core for coil winding, and the single-side fixing assembly is attached to the outer ring of the coil, thereby fixing the outer ring of the coil.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that although it can complete the movement away from the coil winding assembly by pausing the single-side fixing assembly during the winding process, so that each time the copper wire reciprocates up and down to complete the coil winding, the single-side fixing assembly can be attached to the outer ring of the coil to fix the outer ring of the coil, but after the coil on the surface of the core is wound as a whole from top to bottom or from bottom to top, its overall outer diameter will change, and its fixed roller resets on the rotating frame along the arc groove toward the bottom rotating seat with the spline shaft 2 as the center, so that the squeezing force of the fixed roller on the coil gradually increases, which may cause the copper wire to deform, and further may affect the quality of the coil, and it can only complete the winding operation of a single coil at a time, resulting in low coil winding efficiency. Summary of the invention

[0005] The object of the present invention is to solve the problems existing in the prior art. Although it can complete the action of moving away from the coil winding component in a pause mode of the unilateral fixing component during the winding process, so that the unilateral fixing component can be attached to the outer circle of the coil every time the copper wire reciprocates up and down to complete the coil winding, thereby fixing the outer circle of the coil. However, after the coil on the iron core surface winds a whole circle from top to bottom or from bottom to top, its overall outer diameter will change. The fixing roller resets along the arc groove on the rotating frame with the spline shaft two as the center towards the direction of the bottom rotating seat, so that the extrusion force of the fixing roller on the coil gradually increases, which may cause the copper wire to deform, and then may affect the quality of the coil. Moreover, it can only complete the winding operation of a single coil at a time, resulting in low efficiency of coil winding.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows.

[0017] 1. The present invention can drive the lower pulley 2 to rotate by rotating the rotating rod 1, and then under the interaction of the lower pulley 2, the lower belt strip and the lower pulley 1, the lower pulley 1 can drive the rotating rod 3 and the transmission wheel to rotate, the lower pulley 2 rotates half a circle, and the lower pulley 1 rotates a certain angle, the angle is the angle of one stepped arc groove sliding to another stepped arc groove, that is, the angle of one stepped arc groove, the copper wire is wound on the surface of the iron core from top to bottom or from bottom to top, and completes a full circle, and the round rod will be under the reset force of the reset spring 2 Next, slide from a stepped arc groove with a larger radius to another stepped arc groove with a relatively smaller radius, so that the movable rod 2, the fixed roller and the fixed ring move to the side of the transmission wheel, so that the distance between the fixed roller and the iron core increases by a certain distance, which is the thickness of the copper wire. This is repeated. When the copper wire is wound around the surface of the iron core for several turns, the fixed roller is always in contact with the copper wire to limit the position of the copper wire. This can avoid the squeezing of the fixed roller and the coil due to the gradual increase in the outside of the coil, thereby avoiding deformation of the copper wire and ensuring the quality of the coil.

[0018] 2. The present invention controls the motor to start through a controller, so that its output shaft drives the rotating shaft and bevel gear 1 to rotate, and then under the action of the meshing of bevel gear 1 and bevel gear 2, bevel gear 2 can drive rotating rod 2 and the placement disk to rotate, so that the iron core rotates and the copper wire is wound on the surface of the iron core. Since the copper wire is subjected to a pulling force at this time, a force can be applied to the cylinder, and with the cooperation of the ball, the cylinder can be rotated, and synchronously through the rotation of rotating rod 2, the upper pulley 2 can be driven to rotate, and then under the interaction of upper pulley 2, upper belt strip and upper pulley 1, the upper pulley 1 can drive rotating rod 1 and the disk to rotate, and with the cooperation of the disk being set in an inclined shape, an upward force can be applied to the ball, so that the ball Rolling occurs, causing the ball to roll from the bottom of the disc to the top first. At this time, the movable rod 1 and the limiting wheel move upward, driving the copper wire to move upward, and synchronously stretching the reset spring 1. Then the ball rolls from the top of the disc to the bottom. At this time, the movable rod 1 and the limiting wheel move downward under the reset force of the reset spring 1, driving the copper wire to move downward, so that the ball is always in contact with the disc. The movable rod 1 and the limiting wheel drive the copper wire to complete the up and down reciprocating movement, so that the copper wire on the iron core is wound around twice as a whole, the disc rotates one circle, the upper pulley 2 rotates several circles, and the upper pulley 1 rotates one circle. This is repeated, so that the copper wire can be reciprocated up and down on the iron core, so that the winding operation of multiple coils can be completed at the same time, thereby improving the coil winding efficiency.

[0019] 3. In the present invention, when the copper wire moves upward, an upward acting force can be exerted on the pressure roller, causing the movable bar to rotate upward by an appropriate angle around the fixed rod, twisting the torsion spring. Under the restoring acting force of the torsion spring, the pressure roller can always be in contact with the copper wire and exert a reverse acting force to keep the copper wire in a taut state. Conversely, when the copper wire moves downward, under the restoring acting force of the torsion spring, the pressure roller can exert a downward acting force on the copper wire, preventing the copper wire from loosening when it is wound around the iron core surface, thereby ensuring the neatness of the copper wire winding.

[0031] Embodiment, as Figure 1 - Figure 8As shown in the figure, the present invention provides a technical solution: a coil winding device for transformer and inductor windings, comprising: a bottom frame 1, above which a clamping mechanism 2, a reciprocating mechanism 3, a tensioning mechanism 4, a winding mechanism 5 and a coil pressing mechanism 6 are arranged. The winding mechanism 5 includes two fixing plates 501, the bottoms of the two fixing plates 501 are symmetrically and fixedly connected to the bottom of the inner wall of the bottom frame 1, a rotating shaft 502 is rotatably connected to the opposite sides of the two fixing plates 501, and a plurality of first bevel gears 503 are equidistantly and fixedly connected to the outer surface of the rotating shaft 502. One side of one of the fixing plates 501 is fixedly connected with a motor 504, and the output end of the motor 504 is fixedly connected to one end of the rotating shaft 502. A plurality of second rotating rods 505 are rotatably connected to the top of the bottom frame 1 at equal intervals. One end of the second rotating rod 505 is fixedly connected with a placing disc 507, and the other end of the second rotating rod 505 is fixedly connected with a second bevel gear 506. The first bevel gear 503 is meshed with the second bevel gear 506. The reciprocating mechanism 3 includes a plurality of first rotating rods 305. One ends of the plurality of first rotating rods 305 are rotatably connected to the bottom of the inner wall of the bottom frame 1 at equal intervals. A first upper belt pulley 307 is fixedly connected to the outer surface of the first rotating rod 305 near one end, a second upper belt pulley 309 is fixedly connected to the outer surface of the second rotating rod 505, and an upper belt 308 is movably connected to the outer surfaces of the first upper belt pulley 307 and the second upper belt pulley 309. The coil pressing mechanism 6 includes a plurality of third rotating rods 601. The outer surfaces of the plurality of third rotating rods 601 are rotatably connected to the top of the bottom frame 1 at equal intervals. A first lower belt pulley 609 is fixedly connected to one end of the third rotating rod 601, a second lower belt pulley 611 is fixedly connected to the outer surface of the first rotating rod 305 near the other end, and a lower belt 610 is movably connected to the outer surfaces of the first lower belt pulley 609 and the second lower belt pulley 611. The other end of the third rotating rod 601 is fixedly connected with a transmission wheel 602. A U-shaped strip 603 is fixedly connected to the top of the bottom frame 1 near the transmission wheel 602. A plurality of second movable rods 604 are slidably connected to one side of the U-shaped strip 603 at equal intervals. One end of the second movable rod 604 is fixedly connected with a round rod 606, the other end of the second movable rod 604 is fixedly connected with a fixed roller 605, a fixed ring 607 is fixedly connected to the outer surface of the second movable rod 604, and a second return spring 608 is arranged on the outer surface of the second movable rod 604.

[0032] Furthermore, as Figure 1 - Figure 8 shown, one ends of a plurality of second return springs 608 are fixedly connected to one side of the U-shaped strip 603 at equal intervals, and the other ends of the plurality of second return springs 608 are respectively fixedly connected to one side of a plurality of fixed rings 607. Through the above settings, the round rod 606 will slide from a stepped arc-shaped groove with a larger radius to another stepped arc-shaped groove with a relatively smaller radius under the restoring force of the second return spring 608.

[0033] Furthermore, as Figure 1 - Figure 8As shown, the driving wheel 602 is provided with a plurality of stepped arc grooves with different radii. The diameter of the upper pulley one 307 is larger than that of the upper pulley two 309, and the diameter of the lower pulley two 611 is smaller than that of the lower pulley one 609. Through the above settings, when the lower pulley two 611 rotates half a turn, the lower pulley one 609 rotates a certain angle, and the angle is the angle of one stepped arc groove sliding to another stepped arc groove, that is, the angle of one stepped arc groove. The copper wire winds a full circle on the surface of the iron core from top to bottom or from bottom to top. When the disc 306 rotates one circle, the upper pulley two 309 rotates several circles, and the upper pulley one 307 rotates one circle.

[0034] Further, as Figure 1 - Figure 8 shown, the reciprocating mechanism 3 further includes a plurality of first movable rods 301. The plurality of first movable rods 301 are slidably connected to the top of the bottom frame 1 at equal intervals. One end of the first movable rod 301 is fixedly connected with a limiting wheel 302, and a sponge lining is fixedly connected inside the limiting wheel 302. Through the above settings, when the first movable rod 301 and the limiting wheel 302 move up and down reciprocally, the copper wire can be driven to move up and down reciprocally, and through the setting of the sponge lining, the situation of copper wire friction can be avoided.

[0035] Further, as Figure 1 - Figure 8 shown, a first return spring 303 is arranged on the outer surface of the first movable rod 301. One end of the plurality of first return springs 303 is fixedly connected to the top of the bottom frame 1 at equal intervals, and the other end of the plurality of first return springs 303 is fixedly connected to the bottom of the limiting wheel 302 at equal intervals. Through the above settings, when the ball 304 rolls from the topmost part of the disc 306 to the bottommost part, at this time, the first movable rod 301 and the limiting wheel 302 move downward under the restoring force of the first return spring 303, so that the ball 304 is always in contact with the disc 306.

[0036] Further, as Figure 1 - Figure 8 shown, a ball 304 is movably connected to the bottom of the first movable rod 301. One end of the rotating rod one 305 is fixedly connected with a disc 306, and the disc 306 is inclined. Through the above settings, when the rotating rod one 305 drives the disc 306 to rotate, an upward acting force can be applied to the ball 304, causing the ball 304 to roll, so that the ball 304 first rolls from the bottommost part of the disc 306 to the topmost part, and the first movable rod 301 moves upward.

[0037] Further, as Figure 1 - Figure 8As shown, the clamping mechanism 2 includes a U-shaped plate 201. The U-shaped plate 201 is fixedly connected to the bottom frame 1. A plurality of sleeves 202 are fixedly connected to the top of the U-shaped plate 201 at equal intervals. A plurality of circular grooves are formed on the outer surface of the sleeve 202 in a circumferential array. A round bead 206 is movably connected inside the circular groove. By controlling the electric telescopic rod 205 to start through the controller, it extends, pushes the connecting bar 204 to move upward, makes the movable column 203 move upward along the inside of the sleeve 202, makes the conical table surface of the movable column 203 contact the cylinder, and applies a squeezing force to the round bead 206, so that the round bead 206 moves outward from the circular groove and squeezes the inside of the cylinder, thereby fixing the cylinder to a certain extent, so that the cylinder cannot rotate by itself without external interference.

[0038] Further, as Figure 1 - Figure 8 shown, two electric telescopic rods 205 are symmetrically and fixedly connected to the top of the bottom frame 1. One end of the two electric telescopic rods 205 is fixedly connected to a connecting bar 204. A plurality of movable columns 203 are fixedly connected to the top of the connecting bar 204 at equal intervals. The outer surface of the movable column 203 is slidably connected inside the sleeve 202. The top of the movable column 203 is arranged in a conical table shape.

[0039] Further, as Figure 1 - Figure 8 shown, the tensioning mechanism 4 includes two fixed rods 401. One end of the two fixed rods 401 is respectively fixedly connected to the opposite sides of the U-shaped plate 201. One end of the fixed rod 401 is rotatably connected to a movable bar 402. A pressing roller 403 is fixedly connected to the opposite sides of the two movable bars 402. A torsion spring 404 is arranged on the outer surface of the fixed rod 401. The torsion spring 404 is fixedly connected to the U-shaped plate 201 and the movable bar 402 respectively. When the copper wire moves upward, an upward acting force can be applied to the pressing roller 403, so that the movable bar 402 rotates upward around the fixed rod 401 by an appropriate angle, and the torsion spring 404 is twisted. Under the restoring acting force of the torsion spring 404, the pressing roller 403 can always contact the copper wire and apply a reverse acting force to keep the copper wire in a tensioned state. On the contrary, when the copper wire moves downward, under the restoring acting force of the torsion spring 404, the pressing roller 403 can apply a downward acting force to the copper wire.

[0040] Further, as Figure 1 - Figure 8As shown, the winding mechanism 5 further includes an iron core fixing assembly 508. The iron core fixing assembly 508 includes a plurality of fixing blocks. The bottoms of the plurality of fixing blocks are symmetrically and fixedly connected to the tops of a plurality of placing disks 507 in pairs. One side of each fixing block is threadedly connected with a screw rod, and one end of the screw rod is rotatably connected with a clamping block. By placing the iron core on the placing disk 507, the iron core is fixed by the iron core fixing assembly 508. By manually rotating the screw rod, the clamping block is driven to move to one side to clamp and fix the iron core.

[0041] Working principle: When in use, place the iron core on top of the placement plate 507, fix the iron core through the iron core fixing component 508, turn the screw by hand to drive the clamping block to move to one side, clamp and fix the iron core, then put the cylinder wound with copper wire on top of the sleeve 202, and then control the electric telescopic rod 205 to start through the controller, so that it extends, pushes the connecting bar 204 to move upward, makes the movable column 203 move upward along the inside of the sleeve 202, makes the conical table surface of the movable column 203 contact the cylinder, and applies an extrusion force to the ball 206, so that the ball 206 moves outward from the circular groove, extrudes the inside of the cylinder, thereby fixing the cylinder to a certain extent, making the cylinder unable to rotate by itself without external interference. Then pass the copper wire through the inside of the limiting wheel 302 and fix the copper wire on the iron core, making the copper wire arranged in an S shape. Then control the motor 504 to start through the controller, so that its output shaft drives the rotating shaft 502 and the first bevel gear 503 to rotate. Then, under the meshing action of the first bevel gear 503 and the second bevel gear 506, the second bevel gear 506 can drive the second rotating rod 505 and the placement plate 507 to rotate, making the iron core rotate, winding the copper wire on the surface of the iron core. Since the copper wire is subjected to a tensile force at this time, it can apply a force to the cylinder, and with the cooperation of the ball 206, the cylinder can rotate. Synchronously, through the rotation of the second rotating rod 505, the second upper belt pulley 309 can be driven to rotate. Then, under the interaction of the second upper belt pulley 309, the upper belt 308 and the first upper belt pulley 307, the first upper belt pulley 307 can drive the first rotating rod 305 and the disc 306 to rotate. And with the cooperation of the disc 306 being arranged in an inclined shape, an upward force can be applied to the ball 304, making the ball 304 roll, so that the ball 304 first rolls from the bottom of the disc 306 to the top. At this time, the first movable rod 301 and the limiting wheel 302 move upward, driving the copper wire to move upward, and synchronously stretching the first return spring 303. Then the ball 304 rolls from the top of the disc 306 to the bottom. At this time, the first movable rod 301 and the limiting wheel 302 move downward under the restoring force of the first return spring 303, driving the copper wire to move downward, making the ball 304 always contact the disc 306. The first movable rod 301 and the limiting wheel 302 drive the copper wire to complete the up and down reciprocating movement, so that the copper wire on the iron core is wound two circles in total. When the disc 306 rotates one circle, the second upper belt pulley 309 rotates several circles, and the first upper belt pulley 307 rotates one circle. Repeating like this, the copper wire can be wound on the iron core up and down repeatedly, so that the winding operations of multiple coils can be completed simultaneously, thereby improving the efficiency of coil winding. Synchronously, through the rotation of the first rotating rod 305, the second lower belt pulley 611 can be driven to rotate. Then, under the interaction of the second lower belt pulley 611, the lower belt 610 and the first lower belt pulley 609, the first lower belt pulley 609 can drive the third rotating rod 601 and the transmission wheel 602 to rotate. The second lower belt pulley 611 rotates half a circle, and the first lower belt pulley 609 rotates a certain angle.The number of degrees of the angle slides from one stepped arc-shaped groove to another stepped arc-shaped groove, that is, the angle of one stepped arc-shaped groove. The copper wire winds around the surface of the iron core from top to bottom or from bottom to top for a complete circle. In the figure, the return spring two 608 is in a stretched state. Under the return force of the return spring two 608, the round rod 606 will slide from a stepped arc-shaped groove with a larger radius to another stepped arc-shaped groove with a relatively smaller radius, causing the movable rod two 604, the fixed roller 605, and the fixed ring 607 to move towards the transmission wheel 602 side, increasing the distance between the fixed roller 605 and the iron core by a certain distance, which is the thickness of the copper wire. Repeating this process, when winding several turns of copper wire on the surface of the iron core, the fixed roller 605 is always in contact with the copper wire to limit the copper wire. This can avoid the fixed roller 605 being squeezed by the coil due to the gradual increase in the outside of the coil, thereby avoiding the deformation of the copper wire and ensuring the quality of the coil. When the copper wire moves upward, an upward force can be applied to the pressure roller 403, causing the movable bar 402 to rotate upward around the fixed rod 401 by an appropriate angle, twisting the torsion spring 404. Under the return force of the torsion spring 404, the pressure roller 403 can always be in contact with the copper wire and apply a reverse force to keep the copper wire in a taut state. Conversely, when the copper wire moves downward, under the return force of the torsion spring 404, the pressure roller 403 can apply a downward force to the copper wire, preventing the copper wire from loosening when winding around the surface of the iron core and ensuring the neatness of the copper wire winding.
