[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0026] Reference below Figure 1-Figure 4 A wire straightening device 100 according to an embodiment of the present invention is described.

[0027] like Figure 1 As shown, the wire straightening device 100 comprises: a mounting frame 1; a first wire storage wheel 2 and a second wire storage wheel 3, wherein the first wire storage wheel 2 is fixedly mounted on the mounting frame 1, and the second wire storage wheel 3 is rotatably mounted on the mounting frame 1, and the first wire storage wheel 2 and the second wire storage wheel 3 are spaced apart and distributed in the height direction; the outer peripheral wall of the first wire storage wheel 2 is provided with a first wire storage groove 21, and the outer peripheral wall of the second wire storage wheel 3 is provided with a second wire storage groove 31, a driving member 4 is mounted on the mounting frame 1 and is used to drive the wire into the first wire storage groove 21, the wire is wound around the first wire storage groove 21 along a first direction and around the second wire storage groove 31 along a second direction, the first direction and the second direction are opposite, and the free end of the wire is suitable for being connected to an automatic machine.

[0028] Therefore, the first wire storage wheel 2 is a fixed wheel, the second wire storage wheel 3 is a moving wheel, and after the free end of the wire on the wire storage member 7 passes through the driving member 4, it is wound around the first wire storage groove 21 along the first direction and around the second wire storage groove 31 along the second direction to be connected to the automatic machine, wherein the automatic machine can be a wire processing device.

[0029] In actual use, the driving member 4 controls the wire feeding, and the automatic machine continuously consumes the wire. At this time, the wire will drive the second wire storage wheel 3 to rotate. Since the first wire storage wheel 2 does not rotate, the rotation of the second wire storage wheel 3 will give a large pulling force to the wire wound in the first wire storage slot 21 and the second wire storage slot 31 and the wire between the first wire storage wheel 2 and the second wire storage wheel 3. Therefore, by winding and stretching the wire, the bent part of the wire is subjected to considerable reverse bending or stretching, causing a certain elastic-plastic deformation in the part. When the external force is removed, the wire recovers elastically and then becomes straight.

[0030] In this way, the wire can be straightened. It should be noted that, due to the above-mentioned arrangement in the utility model, the pulling force on the wire can be increased, so that ordinary wire can have a good straightening effect, and wires with hard wire skin and strong elasticity can achieve good straightening, as well as high-temperature wires, Teflon wires and wires with poor surface adhesion can also achieve good straightening, which is convenient for the wire processing equipment to better carry out subsequent processing and production.

[0031] At the same time, in the utility model, automatic line change is achieved through the driving member 4, which can reduce manual work, improve production efficiency and reduce production costs.

[0032] According to the wire straightening device 100 of the embodiment of the utility model, when the automatic machine consumes the wire, the driving member 4 can realize automatic wire feeding, and the second wire storage wheel 3 can rotate relative to the mounting frame 1 to facilitate the transmission of the wire to the automatic machine, and the wire is wound around the first wire storage groove 21 and the second wire storage groove 31 in opposite directions in sequence. In this way, during the transmission of the wire, the wire will receive a larger pulling force when passing through the first wire storage wheel 2 and the second wire storage wheel 3, so that it will be straightened, thereby enhancing the straightening effect on the wire.

[0033] It can only straighten ordinary wires. It cannot straighten wires with hard outer skin and strong elasticity. It also cannot straighten some high-temperature wires, Teflon wires and wires with poor surface adhesion, which makes the wire processing equipment unable to straighten the wires.

[0034] In some embodiments, the second storage wheel 3 is slidably mounted on the mounting frame 1 along the height direction.

[0035] For example, the second wire storage wheel 3 may be slidably matched with the mounting frame 1 by means of a slideway and a slide rail, or the second wire storage wheel 3 may be slidably matched with the mounting frame 1 by means of a gear and a rack, which is not limited here.

[0036] Thus, the second wire storage wheel 3 can slide relative to the first wire storage wheel 2 along the mounting frame 1 in the height direction, so that the distance between the first wire storage wheel 2 and the second wire storage wheel 3 is adjustable. In this way, after the automatic machine consumes the wire, the second wire storage wheel 3 can move toward the first wire storage wheel 2 in the height direction to reduce the distance between the first wire storage wheel 2 and the second wire storage wheel 3, so that the distance between the first wire storage wheel 2 and the second wire storage wheel 3 can adapt to the length change of the wire, thereby facilitating the wire feeding stability of the driving member 4, thereby reducing the belt tension of the wire during the wire feeding process, preventing the wire from sliding, and at the same time, allowing the wire to be pulled by a constant pulling force, and the pulling force is always maintained at a low level, so that the straightening process of the wire is gentle and slow, and its high length accuracy is also ensured, thereby preventing the wire skin from shrinking.

[0037] In some embodiments, the wire straightening device 100 further includes: a driving cylinder 5 .

[0038] The driving cylinder 5 is mounted on the mounting frame 1 and is used to apply a force to the second storage wheel 3 to prevent the second storage wheel 3 from rising.

[0039] Therefore, the air cylinder 5 can be driven to apply a force to the second wire storage wheel 3 to hinder the second wire storage wheel 3 from rising, so as to slow down the rising speed of the second wire storage wheel 3, thereby ensuring the wire feeding stability of the driving member 4, thereby reducing the belt tension of the wire during the wire feeding process, preventing the wire from sliding, and at the same time, the wire can be pulled by a constant pulling force, and the pulling force is always maintained at a low level, so that the straightening process of the wire is gentle and slow, and its high length accuracy is also ensured, thereby preventing the wire skin from shrinking.

[0040] In some embodiments, the wire straightening device 100 further includes: a sensing device (not shown in the figure).

[0041] The sensing device is in communication connection with the driving member 4, and the sensing device is configured to control the driving member 4 to feed the wire when the second wire storage wheel 3 rises to a set position.

[0042] For example, the sensing device may be an infrared sensing device, or a position trigger, etc. Thus, the driving member 4 may be controlled by the sensing device to realize automatic wire feeding, thereby reducing manual work and improving wire feeding efficiency.

[0043] In some embodiments, the axial direction of the first storage wheel 2 is parallel to the axial direction of the second storage wheel 3 .

[0044] As a result, the axial direction of the first wire storage wheel 2 and the axial direction of the second wire storage wheel 3 are arranged in the height direction, thereby reducing the space occupied in the axial direction of the first wire storage wheel 2 and the axial direction of the second wire storage wheel 3, and further reducing the size of the wire straightening device 100 in the axial direction of the first wire storage wheel 2 or the axial direction of the second wire storage wheel 3.

[0045] In some embodiments, a plurality of first wire storage grooves 21 are provided, and the plurality of first wire storage grooves 21 are sequentially distributed along the axial direction of the first wire storage wheel 2 .

[0046] Therefore, it is convenient to store multiple turns of wires through the multiple first wire storage grooves 21, so as to achieve the effect of temporarily storing the wires and help improve the straightening efficiency of the wires.

[0047] In some embodiments, a plurality of second wire storage grooves 31 are provided, and the plurality of second wire storage grooves 31 are sequentially distributed along the axial direction of the second wire storage wheel 3 .

[0048] Therefore, it is convenient to store multiple turns of wire through the multiple second wire storage grooves 31, so as to achieve the effect of temporarily storing the straightened wire and help improve the straightening efficiency of the wire.

[0049] In some embodiments, the wire straightening device 100 further includes: a guide wheel 6 , which is rotatably mounted on the mounting frame 1 and located at the front end of the driving member 4 , and the wire is overlapped on the guide wheel 6 .

[0050] For example, there may be multiple guide wheels 6, which are arranged in sequence upstream of the driving member 4. Therefore, when the driving member 4 drives the wire to be fed, the rotation of the multiple guide wheels 6 can improve the wire feeding stability and facilitate guiding the wire.

[0051] In some embodiments, the axial direction of the guide wheel 6 intersects with the axial direction of the first storage wheel 2 .

[0052] For example, the axial direction of the guide wheel 6 is perpendicular to the axial direction of the first wire storage wheel 2, so that the radial space occupied by the first wire storage wheel 2 can be reduced, thereby reducing the radial size of the wire straightening device 100 of the first wire storage wheel 2.

[0053] In any of the above embodiments, one of the first direction and the second direction is a clockwise direction and the other is a counterclockwise direction.

[0054] As a result, the portion of the wire wound around the first wire storage groove 21 and the second wire storage groove 31 and the portion between the first wire storage groove 21 and the second wire storage groove 31 are formed into a serpentine shape, that is, similar to an "S" shape. In this way, when the second wire storage wheel 3 rotates, the pulling force on the wire can be increased, so as to better straighten the wire and improve the straightening effect of the wire.
