Description

[0002] Electromagnetic wire is an insulated wire used to manufacture coils or windings in electrical products. It is also called winding wire and includes round and flat electromagnetic wires. Electromagnetic wire must meet various requirements in terms of use and manufacturing process, including its shape, specifications, and ability to work at high temperatures for short and long periods. During the production process of electromagnetic wire, some small bends are unavoidable, which requires straightening the wire core. If the electromagnetic wire is not straightened, it will easily affect the final winding operation and even affect the normal use of the electromagnetic wire. Therefore, a straightening device is required.

[0003] However, most existing straightening devices use pressure rollers to clamp the electromagnetic flat wire and rely on external force to move the electromagnetic wire to straighten it. But because straightening relies on the movement of the electromagnetic wire to forcibly pull the bent part straight, and because the surface of the pressure roller is arc-shaped, and the contact point between the arc-shaped surface and the flat surface is a line, the pressure roller has poor squeezing ability on the electromagnetic wire. After the electromagnetic wire has a slight wobbling, it will bend due to the change in tensile force, which is inconvenient to use. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings: This embodiment: Please see Figure 1-8 In this embodiment: a straightening device for electromagnetic wire includes: a housing, multiple sets of support plates 3 and a straightening structure.

[0019] In this embodiment, the outer shell consists of an upper cover 1 and a base 2, with the lower end of the upper cover 1 fixedly connected to the upper end face of the base 2.

[0020] In this embodiment, the top cover 1 and the base 2 are used to protect the internal structure.

[0021] The bottom of each support plate 3 is fixedly connected to the base 2 and is located below the electromagnetic wire.

[0022] In this embodiment, the support plate 3 is made of high-strength stainless steel and can be used in conjunction with the straightening structure to straighten the electromagnetic wire. A buffer sponge is provided on the side adjacent to the support plate 3 and the pressing component. During the straightening process, the buffer sponge will be compressed to its limit, which will not affect the straightening of the electromagnetic wire. At the same time, it will prevent the electromagnetic wire from contacting the support plate 3 and the pressing component, thereby protecting the electromagnetic wire. The buffer sponge can be replaced after it wears out.

[0023] The straightening structure is located between the upper cover 1 and the base 2, and above the electromagnetic wire, for straightening the electromagnetic wire. The straightening structure includes multiple sets of pressing components, each set of pressing components is located directly above the support plate 3, and there is a height difference between two adjacent sets of pressing components, so that the pressing components cooperate with the support plate 3 to straighten the electromagnetic wire.

[0024] In this embodiment, by operating the straightening structure, multiple sets of pressing components move vertically in batches. As the electromagnetic wire moves, it is straightened in all directions. The contact area between the pressing components and the electromagnetic wire is surface-to-surface, which increases the contact area and thus improves the squeezing ability of the electromagnetic wire, straightening the bends. The surface-to-surface contact also prevents the electromagnetic wire from shaking and bending after straightening, making it easy to use.

[0025] like Figure 2 and 4 As shown, the straightening structure also includes: a rotating component 9, two sets of first connecting components 8, two sets of fixing rods 7, and a driving assembly.

[0026] The center of the rotating component 9 is rotatably connected to the upper cover 1; both ends of the rotating component 9 are provided with a first sliding groove.

[0027] In this embodiment, the upper cover 1 can support the rotation of the rotating component 9.

[0028] Each first connecting member 8 consists of a first cylindrical pin and a connecting plate. The first cylindrical pin passes through the connecting plate and is fixedly connected to the connecting plate. The first cylindrical pin is set in the first sliding groove and is slidably connected to the rotating member 9 through the first sliding groove.

[0029] In this embodiment, when the rotating member 9 rotates, the first connecting member 8 moves vertically through the sliding between the first sliding groove and the first cylindrical pin.

[0030] Each set of fixing rods 7 is fixedly connected to the end of the connecting plate away from the rotating part 9, and the surface of the fixing rods 7 is fixedly connected to the pressing components spaced apart.

[0031] In this embodiment, the first connector 8 will drive the spaced fixed rods 7 to move synchronously; this can realize the alternating straightening of the pressing components, so that the electromagnetic wire is fully straightened.

[0032] The drive assembly is fixedly connected to a set of fixed rods 7.

[0033] In this embodiment, the fixed rod 7 connected to it can be moved vertically by the driving component, and this set of fixed rods 7 can be moved in the opposite direction by another set of fixed rods 7 through the first connecting member 8 and the rotating member 9.

[0034] When straightening is required, the drive assembly is activated, which causes the fixed rod 7 connected to it to move vertically downward. This set of fixed rods 7 will drive the first connecting piece 8 on the same side to move. This set of first connecting pieces 8 will slide between the first sliding groove and the first cylindrical pin, causing the rotating piece 9 to rotate under the support of the upper cover 1. The rotating piece 9 will cause another set of first connecting pieces 8 to drive the fixed rod 7 to move in the opposite direction. The two sets of fixed rods 7 simultaneously drive the pressing assembly to move, causing the pressing assembly to hit the electromagnetic wire and straighten the electromagnetic wire.

[0035] like Figure 6 and 7 As shown, the drive assembly includes: a first slot plate 10, a second connector 13, a turntable 11, a gearbox 14, and a motor 12.

[0036] Specifically, one end of the first groove plate 10 is fixedly connected to one end of a set of fixing rods 7; a second sliding groove is provided on the surface of the first groove plate 10.

[0037] In this embodiment, the first groove plate 10 can drive the fixed rod 7 connected to it to move vertically.

[0038] The second connector 13 consists of a second cylindrical pin and a circular plate. One end of the second cylindrical pin is fixedly connected to the circular plate. The second cylindrical pin is disposed in the second sliding groove and is slidably connected to the first groove plate 10 through the second sliding groove. One side edge of the turntable 11 is fixedly connected to the other end of the second cylindrical pin.

[0039] In this embodiment, as the turntable 11 rotates, the second connector 13 located at the edge of the turntable 11 will revolve around the rotation axis of the turntable 11. At this time, the sliding between the second cylindrical pin and the second slide groove is used to make the first groove plate 10 move vertically.

[0040] The output end of the gearbox 14 is fixedly connected to the shaft of the turntable 11; the output end of the motor 12 is fixedly connected to the input end of the gearbox 14.

[0041] In this embodiment, the model of motor 12 is selected according to actual needs, as long as it meets the working conditions; the gearbox 14 can reduce the output speed of motor 12.

[0042] When it is necessary to drive the fixed rod 7 to move, the motor 12 is started. After the output end of the motor 12 is reduced by the reduction gearbox 14, it drives the turntable 11 to rotate. The turntable 11 will cause the second connecting piece 13 located at the edge to revolve around the rotation axis of the turntable 11. At this time, the sliding between the second cylindrical pin and the second slide groove is used to make the first groove plate 10 move vertically. The first groove plate 10 will drive the fixed rod 7 connected to it to move.

[0043] like Figure 4 and 5As shown, each pressing assembly includes: a slider 6, a hollow plate 5, and a pressing plate 4.

[0044] One end of the sliding member 6 is fixedly connected to the upper cover 1; the hollow plate 5 is sleeved on the surface of the sliding member 6 and is slidably connected to the sliding member 6; the surface of the hollow plate 5 is fixedly connected to the connecting plate.

[0045] In this embodiment, the sliding member 6 can be used to restrict the hollow plate 5 to move only vertically.

[0046] The surface of the straightening plate 4 is fixedly connected to the end of the hollow plate 5 away from the sliding member 6.

[0047] In this embodiment, the hollow plate 5 can drive the straightening plate 4 to move vertically, and the straightening plate 4 is used to straighten the electromagnetic wire.

[0048] During the straightening process, the electromagnetic wire will be subjected to a vertical force, causing the two sides of the electromagnetic wire to curl up, which affects the straightening efficiency.

[0049] To address the aforementioned issues, this embodiment proposes an implementation method in which the electromagnetic wire straightening device further includes a stabilizing structure; the stabilizing structure is disposed between the straightening structure and the support plate 3, and is used to stabilize the electromagnetic wire.

[0050] like Figure 8 As shown, the stabilizing structure includes: a stabilizing plate 18, a second groove plate 15, a third connecting piece 16, and an electric push rod 17.

[0051] Specifically, the lower end face of the second groove plate 15 is fixedly connected to the upper end face of the stabilizing plate 18; a third sliding groove is provided on the surface of the second groove plate 15.

[0052] In this embodiment, the second slot plate 15 will drive the stabilizing plate 18 to move vertically. By placing the stabilizing plate 18 close to the upper surface of the electromagnetic wire, the electromagnetic wire cannot be tilted up, thus stabilizing the electromagnetic wire, while not restricting the movement of the electromagnetic wire.

[0053] The third connector 16 consists of a third cylindrical pin and a square frame. The two ends of the third cylindrical pin are fixedly connected to one end of the square frame. The third cylindrical pin is set in the third sliding groove and is slidably connected to the second groove plate 15 through the third sliding groove.

[0054] In this embodiment, since the third slide is an inclined slide, when the third connector 16 moves horizontally, the second groove plate 15 moves vertically by sliding between the third cylindrical pin and the third slide.

[0055] The output end of the electric actuator 17 is fixedly connected to the other end of the square frame.

[0056] In this embodiment, the model of the electric push rod 17 is selected according to actual needs, as long as it meets the working conditions.

[0057] When stabilizing the wire is required, adjust the electric push rod 17 so that the output end of the electric push rod 17 pushes the square frame to move horizontally. The square frame simultaneously drives the third cylindrical pin to move, and the sliding between the third cylindrical pin and the third slide groove causes the second groove plate 15 to move vertically downward. The second groove plate 15 drives the stabilizing plate 18 to move synchronously, so that the stabilizing plate 18 is suspended above the electromagnetic wire, and the distance between the electromagnetic wires is kept at about 2 cm. This can prevent the sides of the electromagnetic wire from lifting up, while not hindering the movement of the electromagnetic wire.

[0058] like Figure 8 As shown, the stabilizing structure also includes: two sets of limiting members 19, each set of limiting members 19 consisting of a horizontal bar and two sets of vertical bars, one end of the two sets of vertical bars being fixedly connected to the horizontal bar, and the other end being fixedly connected to the upper cover 1; the surfaces of the two sets of vertical bars penetrate the stabilizing plate 18 and are slidably connected to the stabilizing plate 18.

[0059] In this embodiment, the sliding between the limiting member 19 and the stabilizing plate 18 restricts the stabilizing plate 18 to move only vertically.

[0060] like Figure 8 As shown, the angle between the third groove and the horizontal plane is an acute angle.

[0061] The electromagnetic wire straightening device also includes: two sets of limiting structures; the two sets of limiting structures are symmetrically arranged at both ends of the base 2 to limit the position of the electromagnetic wire.

[0062] like Figure 3 As shown, each set of limiting structures includes: two sets of limiting plates 23, two sets of moving parts 20, a double-ended threaded rod 21, and a handwheel 22.

[0063] Two sets of limiting plates 23 are symmetrically arranged on both sides of the electromagnetic wire; one end of the limiting plate 23 is slidably connected to the base 2.

[0064] In this embodiment, by moving the two sets of limiting plates 23 to both sides of the electromagnetic wire and keeping them about 2 cm away from the electromagnetic wire, it can be ensured that the electromagnetic wire will not deviate during the movement, thus limiting the position of the electromagnetic wire.

[0065] The lower end face of each set of moving parts 20 is fixedly connected to the other end of the limiting plate 23; the double-headed threaded rod 21 passes through the two sets of moving parts 20 and is threadedly connected to the two sets of moving parts 20.

[0066] In this embodiment, since the threads on both sides of the double-threaded rod 21 are in opposite directions, when the double-threaded rod 21 rotates, the two sets of moving parts 20 will move in opposite directions.

[0067] The shaft of the handwheel 22 is fixedly connected to one end of the double-threaded rod 21.

[0068] In this embodiment, the double-ended threaded rod 21 is rotated synchronously by rotating the handwheel 22.

[0069] When it is necessary to restrict the movement of the electromagnetic wire, the user can turn the handwheel 22, which will drive the double-threaded rod 21 to rotate. Since the threads on both sides of the double-threaded rod 21 are opposite, the two sets of moving parts 20 move towards the middle at the same time. The moving parts 20 also drive the limiting plate 23 to move, moving the limiting plate 23 to both sides of the electromagnetic wire and keeping it about 2 cm away from the electromagnetic wire. This ensures that the electromagnetic wire will not deviate during the movement and restricts the position of the electromagnetic wire.

[0070] Working principle: When using the electromagnetic wire straightening device, the electromagnetic wire is passed through the device. When it is necessary to restrict the movement of the electromagnetic wire, the user turns the handwheel 22. The handwheel 22 will drive the double-threaded rod 21 to rotate. Since the threads on both sides of the double-threaded rod 21 are opposite, the two sets of moving parts 20 move towards the middle at the same time. The moving parts 20 simultaneously drive the limiting plate 23 to move. The limiting plate 23 is moved to both sides of the electromagnetic wire and kept about 2 cm away from the electromagnetic wire. This ensures that the electromagnetic wire will not deviate during the movement and restricts the position of the electromagnetic wire.

[0071] When stabilizing the wire is required, adjust the electric push rod 17 so that the output end of the electric push rod 17 pushes the square frame to move horizontally. The square frame simultaneously drives the third cylindrical pin to move, and the sliding between the third cylindrical pin and the third slide groove causes the second groove plate 15 to move vertically downward. The second groove plate 15 drives the stabilizing plate 18 to move synchronously, so that the stabilizing plate 18 is suspended above the electromagnetic wire, and the distance between the electromagnetic wires is kept at about 2 cm. This can prevent the sides of the electromagnetic wire from lifting up, while not hindering the movement of the electromagnetic wire.

[0072] When straightening is required, the motor 12 is started. After the output end of the motor 12 is reduced by the reduction gearbox 14, it drives the turntable 11 to rotate. The turntable 11 will cause the second connecting piece 13 located at the edge to revolve around the rotation axis of the turntable 11. At this time, the sliding between the second cylindrical pin and the second slide groove is used to make the first groove plate 10 move vertically. The first groove plate 10 will drive the fixed rod 7 connected to it to move vertically downward. This set of fixed rods 7 will drive the first connecting piece 8 on the same side to move. This set of first connecting pieces 8 will slide between the first slide groove and the first cylindrical pin, so that the rotating piece 9 will rotate under the support of the upper cover 1. The rotating piece 9 will cause another set of first connecting pieces 8 to drive the fixed rod 7 to move in the opposite direction. The two sets of fixed rods 7 simultaneously drive the pressing component to move, so that the pressing component hits the electromagnetic wire and straightens the electromagnetic wire, thus completing the use of this device.
