Description

Technical Field

[0001] This invention relates to the field of enameled wire winding technology, specifically to a bidirectional synchronous winding mechanism and winding machine. Background Technology

[0002] Self-adhesive cement wire is a type of special cement wire. It adopts a composite structure design of baseline, nylon layer and self-adhesive layer. The baseline undertakes the main insulation function. When winding the coil, the enamel impregnation process can be omitted. It is suitable for hollow cup motors, disc motors, electronic transformers and other fields. It is especially suitable for the manufacture of frameless electromagnetic coils.

[0003] In the field of wireless charging, we often see coils of various sizes, materials, and shapes widely used in both transmitting and receiving products. The Alpha coil, also known as the alpha coil, gets its name from its shape, where both leads are on the outside of the coil, resembling an α. The Alpha coil is a single-wire, double-layer coil. The first layer is wound from the outside in, and the second layer is wound from the inside out. Both layers are made from the same conductor. When energized, the current direction is either both counter-clockwise or both clockwise. Therefore, for coils of the same outer diameter, the Alpha coil has a stronger magnetic field.

[0004] The existing invention CN112951588A provides an alpha coil winding device, while this invention provides another alpha coil winding device.

There is a horizontal gap between the clamping assembly and the end of the guide rod. When the clockwise and counterclockwise rotating parts rotate clockwise at the same time, the enameled wire between the clamping assembly and the extrusion rod is wound clockwise on the surface of the extrusion rod. When the clockwise rotating part rotates clockwise and the counterclockwise rotating part is stationary, the enameled wire between the clamping assembly and the guide rod is wound counterclockwise on the surface of the extrusion rod.

[0013] Secondly, the present invention also provides a winding machine for operating the aforementioned bidirectional synchronous winding mechanism to wind coils, comprising a worktable fixedly mounted at the bottom of the U-shaped frame, a first driving assembly and a second driving assembly fixedly mounted at the top of the worktable for driving the forward and reverse rotating components to rotate, a plurality of slide rods fixedly mounted on the side of the U-shaped frame away from the forward rotating component, a sliding frame slidably mounted on the plurality of slide rods, a telescopic assembly for driving the extrusion rod to extend and retract within the reverse rotating component mounted on one side of the sliding frame, the reverse rotating component passing through the sliding frame and rotatably connected to the sliding frame, an adjusting assembly for adjusting the distance between the sliding frame and the U-shaped frame fixedly mounted at the top of the U-shaped frame, and a telescopic wire cutter for cutting the enameled wire also mounted at the top of the worktable.

The second drive assembly includes a second motor fixedly mounted on one side of the sliding frame, a third pulley fixedly mounted on the output shaft end of the second motor, a fourth pulley fixedly mounted on the end of the reverse rotating member, and a second transmission belt externally meshing on the third pulley and the fourth pulley.

[0015] Preferably, the telescopic assembly includes a second hydraulic module fixedly installed on one side of the sliding frame, and a rotary joint fixedly installed between one end of the extrusion rod and the output end of the second hydraulic module.

[0016] Preferably, the adjustment assembly includes a horizontal plate fixedly installed on the top of the U-shaped frame, a third motor and two vertical plates fixedly installed on the horizontal plate, and a threaded rod fixedly installed at the output end of the third motor. The threaded rod is rotatably connected to the two vertical plates and passes through them, particularly the vertical plate near the third motor. The threaded rod also passes through the sliding frame and is threadedly connected to it.

[0017] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0018] 1. This invention uses the telescopic rod inside the counter-rotating component to cooperate with the abutting component on the forward rotating component to clamp the elongated enameled wire after the XYZ three-axis module is clamped. When the forward rotating component and the counter-rotating component rotate forward synchronously, the enameled wire between the XYZ three-axis module and the counter-rotating component is wound clockwise on the extrusion rod. When the counter-rotating component is stationary and the forward rotating component rotates forward, the enameled wire between the second roller and the forward rotating component is wound counterclockwise on the extrusion rod, thereby winding the enameled wire into an alpha coil and quickly realizing the winding of the alpha coil;

[0019] 2. This invention, through the coordination between the adjustment component, the telescopic component, the clamping component, and the telescopic wire cutter, first cuts the enameled wire between the clamping component and the counter-rotating component, allowing the clamping component to move the enameled wire with the alpha coil above the receiving frame and no longer clamp it, and then returns to the forward rotating component and the second roller to clamp the enameled wire, thereby pulling the newly wound alpha coil and enameled wire again to a predetermined length for the next winding of the alpha coil, thus achieving automated production;

[0020] 3. At the same time, when winding the alpha coil, the present invention can adjust the spacing between the reverse and forward winding components by adjusting the components to adjust the spacing according to the thickness of the enameled wire. At the same time, a certain pressure can be applied to compact the coil after winding, making the alpha coil more compact. Combined with the self-adhesive enameled wire, it ensures that the alpha coil will not loosen after winding.

[0021] 4. At the same time, the shape of the extrusion rod can be adjusted according to the requirements of the present invention, so as to automatically produce alpha coils of different shapes in batches;

[0022] 5. The present invention can also adjust the number of turns of the forward rotating component and the length of the enameled wire between the clamping component and the reverse rotating component according to the needs, thereby adjusting the number of turns of the two layers of the alpha coil with different windings. With the mutual clamping of the contact component and the reverse rotating component, non-standard alpha coils with different thicknesses can be obtained by winding clockwise and counterclockwise.

[0032] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] This invention provides, for example Figure 1-6The illustrated bidirectional synchronous winding mechanism is used to continuously and automatically wind self-adhesive enameled wire 1 into an alpha coil 2. It mainly includes a U-shaped frame 3, with a forward-rotating component 4 and a reverse-rotating component 5, whose central axes coincide, respectively, passing through and rotatably mounted on both sides of the U-shaped frame 3. A contact component 6 is rotatably mounted on one end of the forward-rotating component 4 near the reverse-rotating component 5, and a blind hole 8a is opened at the other end. A through hole 8b, communicating with the inner end of the blind hole 8a, is opened on the outer circumference surface. The blind hole 8a and the through hole 8b constitute a conveying hole 8. A first roller 12 is rotatably mounted inside the through hole 8b. Meanwhile, a positioning ring 7a is fixedly installed on the outer circumference of the forward rotating component 4. Two extension rods 7b are fixedly installed on the side of the positioning ring 7a near the through hole 8b. A second roller 7c is rotatably installed between the ends of the two extension rods 7b. The positioning ring 7a, the extension rods 7b, and the second roller 7c constitute the guide rod 7. A pressing rod 9 is installed through the reverse rotating component 5 and slides along its length. An XYZ three-axis module 10 is provided on the top of the U-shaped frame 3. A mounting bracket 11a is fixedly installed at the output end of the XYZ three-axis module 10. The bottom of the mounting bracket 11a is fixedly mounted with a mounting bracket 11a. The mounting bracket 11a, L-shaped rod 11b, and first hydraulic module 11c are fixedly mounted on it. A downward pressure rod 11d is fixedly mounted on the output end of the first hydraulic module 11c. The mounting bracket 11a, L-shaped rod 11b, first hydraulic module 11c, and downward pressure rod 11d constitute a clamping assembly 11 that clamps the end of the enameled wire 1. When the enameled wire 1 passes through the blind hole 8a and through hole 8b, and then passes through the outer circumference of the first roller 12 and second roller 7c, it is clamped by the downward pressure rod 11d and L-shaped rod 11b. The XYZ three-axis module 10 is connected via the mounting bracket 11a, The first hydraulic module 11c and the L-shaped rod 11b drive the enameled wire 1 to lengthen, making the enameled wire 1 taut, and the enameled wire 1 is perpendicular to the central axis of the forward rotating member 4. The distance between the L-shaped rod 11b and the forward rotating member 4 is slightly larger than the length of the enameled wire 1 wound on the extrusion rod 9 to form half of the alpha coil 2. Then the extrusion rod 9 extends out from the reverse rotating member 5, and the end of it presses the enameled wire 1 onto the contact member 6. Here, the surface of the contact member 6 may have a recess that matches the shape of the end of the extrusion rod 9, so that the extrusion rod 9 can restrict the rotation of the contact member 6 when it extends into the recess.

[0035] Then, the forward rotating part 4 and the reverse rotating part 5 start to rotate forward simultaneously. At this time, the XYZ three-axis module 10 drives the clamping component 11 to move towards the forward rotating part 4. The enameled wire 1 between the clamping component 11 and the forward rotating part 4 begins to gradually wind clockwise around the extrusion rod 9. After rotating a predetermined number of times, the reverse rotating part 5, the forward rotating part 4, and the XYZ three-axis module 10 stop simultaneously. The forward rotating part 4 begins to rotate independently a predetermined number of times. At this time, the forward rotating part 4 drives the positioning ring 7a, the positioning ring 7a drives the extension rod 7b, and the extension rod 7b drives the second roller 7c. This causes the enameled wire 1 between the second roller 7c and the extrusion rod 9 to gradually wind counterclockwise around the extrusion part. Since the contact part 6 cooperates with the extrusion part to clamp the enameled wire 1, the contact part 6 cannot rotate with the forward rotating part 4, but remains stationary like the reverse rotating part 5.

[0036] Then the anti-rotating part 5 moves a certain distance in the direction of extension of one end of the forward rotating part 4 to reduce the gap between the anti-rotating part 5 and the contacting part 6. In order to ensure the thickness of the alpha coil 2 winding, we fix the first extrusion ring 13 and the second extrusion ring 14 at opposite ends of the contacting part 6 and the anti-rotating part 5, respectively.

[0037] Then, the forward rotating part 4 and the reverse rotating part 5 start to rotate forward again simultaneously, cooperating with the XYZ three-axis module 10 to wind half of the alpha coil 2 clockwise on the surface of the extrusion rod 9, which contacts the surface of the second extrusion ring 14; then, after all three stop, the forward rotating part 4 rotates forward again for the same number of turns, winding the enameled wire 1 counterclockwise on the extrusion rod 9, which contacts the surface of the first extrusion ring 13; then, the steps of the forward rotating part 4 and the reverse rotating part 5 rotating in the same direction, and the forward rotating part 4 rotating alone are repeated until half of the alpha coil 2 is wound clockwise and half counterclockwise on the surface of the extrusion rod 9, and then the reverse rotating part 5 moves a certain distance towards the contact part 6 again, providing extrusion force to the alpha coil 2 and remaining still for a period of time to complete the winding of the alpha coil 2;

[0038] In conjunction with a bidirectional synchronous winding mechanism, the present invention also provides a winding machine for operating a bidirectional synchronous winding mechanism to perform continuous coil winding. The machine includes a worktable 15 fixedly mounted at the bottom of a U-shaped frame 3, a telescopic wire cutter 22 fixedly mounted at the top of the worktable 15 for cutting the enameled wire 1 between the clamping assembly 11 and the extrusion rod 9, a first motor 16a fixedly mounted on one side of the U-shaped frame 3, a first pulley 16b fixedly mounted at the end of the output shaft of the first motor 16a, a second pulley 16c fixedly mounted through one end of the U-shaped frame 3 via a forward rotating member 4, and a first transmission belt 16d meshing with both the first pulley 16b and the second pulley 16c. The first motor 16a, the first pulley 16b, the second pulley 16c, and the first transmission belt 16d constitute the first driving assembly 16 for driving the forward rotating member 4 to rotate. A sliding frame 19 is provided on the other side of the U-shaped frame 3. The reverse rotating member 5 passes through the sliding frame 19 and is slidably connected to it. A second motor 17a is fixedly mounted on the sliding frame 19. A third pulley 17b is fixedly mounted on the output end of the second motor 17a. A fourth pulley 17c is fixedly mounted on one end of the reverse rotating member 5 passing through the sliding frame 19. A second transmission belt 17d is mounted on the third pulley 17b and the fourth pulley 17c. The second motor 17a, the third pulley 17b, and the fourth pulley 16d form the first driving assembly 16 for driving the forward rotating member 4 to rotate. c and the second transmission belt 17d constitute the second drive assembly 17 for driving the counter-rotating component 5 to rotate. To ensure that the counter-rotating component 5 can move closer to or further away from the forward rotating component 4 as needed, a horizontal plate 21a is fixedly installed on the top of the U-shaped frame 3. Two vertical plates 21c and a third motor 21b are fixedly installed on the top of the horizontal plate 21a. A threaded rod 21d is fixedly installed at the output end of the third motor 21b. The threaded rod 21d is rotatably connected to the two vertical plates 21c and is also threadedly connected to the sliding frame 19. Multiple sliding rods 18 are installed through and slidably inside the sliding frame 19. The sliding rods 18 are fixedly connected to the side wall of the U-shaped frame 3. Thus, the third motor 21b, The threaded rod 21d, the vertical plate 21c, and the horizontal plate 21a constitute the adjustment assembly 21 that drives the sliding frame 19 to move closer to and further away from the U-shaped frame 3. When the sliding frame 19 moves, it will drive the anti-rotating member 5 to move horizontally. In order to ensure that the extrusion rod 9 can extend and retract from the anti-rotating member 5 to clamp the enameled wire 1 on the surface of the contact member 6, a second hydraulic module 20a is fixedly installed on the sliding frame 19. A rotary joint 20b is fixedly installed between the output end of the second hydraulic module 20a and the end of the extrusion rod 9 that passes through the anti-rotating member 5. The second hydraulic module 20a and the rotary joint 20b constitute the telescopic assembly 20 that drives the extrusion rod 9 to extend and retract in the anti-rotating member 5.

[0039] When the output shaft of the first motor 16a rotates, it drives the first pulley 16b. The first pulley 16b drives the second pulley 16c through the first transmission belt 16d. The second pulley 16c drives the forward rotating component 4 to rotate. When the output shaft of the second motor 17a rotates, it drives the third pulley 17b. The third pulley 17b drives the fourth pulley 17c through the second transmission belt 17d. The fourth pulley 17c drives the reverse rotating component 5 to rotate. The reverse rotating component 5 drives the internal pressure rod to rotate. The pressing rod 9 drives the contact component 6 to rotate synchronously through its cooperation with the contact component 6.

[0040] When the alpha coil 2 is wound on the extrusion rod 9, the telescopic wire cutter 22 cuts the enameled wire 1 between the clamping assembly 11 and the contact member 6, and then retracts. At this time, the XYZ three-axis module 10 moves the L-shaped rod 11b between the counter-rotating member 5 and the second roller 7c. In conjunction with the first hydraulic module 11c driving the pressing rod 11d, it clamps the enameled wire 1 between the second roller 7c and the forward rotating member 4 onto the L-shaped rod 11b. Then, the output shaft of the second hydraulic module 20a shortens, and through the rotary joint 20b, it drives the extrusion rod 9 to no longer clamp the enameled wire 1 onto the contact member 6, causing the extrusion rod 9 to retract into the counter-rotating member 5, allowing the wound alpha coil 2 to separate from the extrusion rod 9. At the same time, the adjusting assembly 21 moves the sliding frame 19 away from the forward rotating member 4, and the sliding frame 19 will move the counter-rotating member 5 away from the forward rotating member 4. After that, the XYZ three-axis module... 10. Pull the clamped enameled wire 1 so that there is a distance between the enameled wire 1 and the central axis of the forward rotating part 4 that is slightly longer than the length of half an alpha coil 2. Then, follow the above winding steps to wind the enameled wire 1 clockwise and counterclockwise on the extrusion rod 9 to form the alpha coil 2. At this time, the telescopic wire cutter 22 cuts the enameled wire 1 between the clamping assembly 11 and the contacting part 6 and then retracts. At this time, the XYZ three-axis module 10 drives the L-shaped rod 11b to move directly above the receiving frame. The output shaft of the first hydraulic module 11c shortens, causing the lower pressure rod 11d to no longer cooperate with the L-shaped rod 11b to clamp the enameled wire 1 with the alpha coil 2. The alpha coil 2 falls into the receiving frame. The XYZ three-axis module 10 then drives the L-shaped rod 11b to move between the reverse rotating part 5 and the second roller 7c. Repeat the above operation to realize automated production operation.

[0041] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), installation arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application.
