Description

Technical Field

[0001] The present invention relates to the technical field of wire harness production, and in particular to a core wire twisting method and equipment based on a multi-core wire harness. Background Art

[0002] A multi-core wire harness is a whole composed of multiple single-strand core wires that are twisted or tied together. It includes the wire harness body and multiple core wires with the shielding layer stripped off at the end of the wire harness.

[0003] The core wires at the ends of the wiring harness need to be crimped with terminals. When crimping the terminals, the core wires at the ends of the wiring harness are required to be spread out.

[0004] In the related art, a method of spreading out the core wires at the end of the wire harness is to spread out the core wires manually.

[0005] However, the traditional core wire spreading method does not make the core wire straight after spreading. In particular, after spreading multiple core wires at the ends of the twisted wire, the core wire is still bent, resulting in poor quality of the core wire spreading. The core wire needs to be further straightened before the next process, which reduces production efficiency. Summary of the Invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a core wire twisting method based on a multi-core wire bundle, which can simultaneously twist and straighten the core wires, improve the quality of the core wire twisting, and improve production efficiency.

[0007] The present invention also proposes a core wire twisting device for implementing the above-mentioned core wire twisting method based on a multi-core wire bundle.

[0008] According to a first aspect of an embodiment of the present invention, a core wire twisting method based on a multi-core wire harness comprises a wire harness body and a plurality of core wires whose shielding layers have been stripped off at the ends of the wire harness. The core wire twisting method comprises the following steps: Extending an end portion of the multi-core wire harness along a first direction and placing the end portion between a first washboard and a second washboard arranged side by side along a second direction, wherein the first direction and the second direction are perpendicular to each other; Controlling the first washboard and the second washboard to move relative to each other along a third direction to spread out the multiple core wires at the end of the multi-core wire harness, wherein the first direction, the second direction and the third direction are perpendicular to each other; The first rubbing plate and the second rubbing plate are controlled to move synchronously along the first direction to straighten the core wires at the end of the multi-core wire harness.

[0009] The core wire twisting method based on a multi-core wire harness according to an embodiment of the present invention has at least the following beneficial effects: 1. The present invention extends the end of a multi-core wire bundle along a first direction and places it between a first rubbing plate and a second rubbing plate arranged side by side along a second direction, and controls the first rubbing plate and the second rubbing plate to move relative to each other along a third direction. Thus, by utilizing the friction force of the first rubbing plate and the second rubbing plate on the core wire, when the first rubbing plate and the second rubbing plate move relative to each other along the first direction, they can drive the core wire of the wire bundle to be rubbed to move along the first direction, so that the multiple core wires of the wire bundle to be rubbed can be spread out in a flat distribution state, thereby achieving efficient and uniform spreading of the core wires and improving the initial neatness of the spreading of the core wires.

[0010] 2. The present invention controls the first rubbing board and the second rubbing board to move synchronously along the first direction, thereby utilizing the friction force of the first rubbing board and the second rubbing board on the core wire. The first rubbing board and the second rubbing board move synchronously along the first direction so as to straighten the bent core wire longitudinally, ensure that the core wire is straight after the rubbing is completed, improve the quality of the core wire spreading, and improve production efficiency.

[0011] 3. The present invention controls the first rubbing plate and the second rubbing plate to move relative to each other along the third direction, and controls the first rubbing plate and the second rubbing plate to move synchronously along the first direction, thereby straightening the core wire longitudinally while rubbing the core wire loose, thereby solving the problems of core wire bending and poor uniformity in traditional methods, avoiding secondary manual straightening of the core wire, and significantly improving the quality of core wire loosening and production efficiency.

[0012] According to some embodiments of the present invention, the core thread twisting method further includes the following step: after twisting the core threads apart, moving the scattered core threads to close the gaps between the plurality of core threads.

[0013] Advantageously, the present invention moves the scattered core wires to close the gaps between the multiple core wires after the core wires are twisted apart, thereby actively moving the core wires to close the gaps after the core wires are twisted apart, avoiding excessive lateral deviation of the core wires after the multiple core wires are spread apart, and ensuring that the core wires are tightly and neatly arranged.

[0014] According to some embodiments of the present invention, moving the scattered core wires includes the following step: moving the core wires from one side of the core wire spreading direction toward the axis of the end portion of the multi-core wire harness.

[0015] Advantageously, the present invention moves the core wires toward the axis of the end of the multi-core wire bundle from one side of the core wire spreading direction, thereby allowing the spread core wires to move toward the axis of the end of the multi-core wire bundle and preventing the core wires from being bent outward.

[0016] According to some embodiments of the present invention, the core thread twisting method further includes the following steps: in the process of twisting the core thread, controlling the first rubbing plate and the second rubbing plate to approach each other along the second direction so that the first rubbing plate and the second rubbing plate remain in contact with the core thread.

[0017] What is beneficial is that: the present invention controls the first rubbing plate and the second rubbing plate to approach each other along the second direction during the process of rubbing the core wires. It can be understood that when the multiple core wires at the end of the multi-core wire harness are in a tangled state, the diameter of the end of the multi-core wire harness is large, and in the process of the core wires being rubbed out, the height of the end of the multi-core wire harness along the second obstacle will gradually decrease. By controlling the first rubbing plate and the second rubbing plate to approach each other along the second direction during the process of rubbing the core wires, the first rubbing plate and the second rubbing plate can continuously reduce the distance between them during the process of rubbing the core wires, thereby maintaining contact with the core wires, avoiding the distance between the first rubbing plate and the second rubbing plate being too large, which will cause the first rubbing plate and the second rubbing plate to be unable to fully rub out the core wires, and thus, it is beneficial to ensure the rubbing effect of the core wires.

[0018] According to some embodiments of the present invention, the core wire twisting method further includes the following step: heating the core wires at the ends of the multi-core wire bundle during the process of twisting the core wires straight.

[0019] The benefit is that: the present invention heats the core wires at the ends of the multi-core wire harness during the process of straightening the core wires. It can be understood that by heating the core wires, the core wire skin is softened, making the core wire easier to straighten during the straightening process and reducing bending residue. In addition, the core wire after the core wire skin is heated and softened is straightened and then cooled, which can make the cooled core wire easier to maintain the straightened state, effectively avoiding the core wire rebound bending, thereby improving the straightening effect.

[0020] According to some embodiments of the present invention, controlling the first rubbing plate and the second rubbing plate to move synchronously along the first direction includes the following steps: while the first rubbing plate and the second rubbing plate rub multiple core wires apart, controlling the first rubbing plate and the second rubbing plate to move synchronously along the first direction to synchronously rub and straighten the core wires at the end of the multi-core wire bundle.

[0021] Advantageously, the present invention straightens the core wire while spreading it out, so that spreading and straightening are performed simultaneously, which can shorten the process time and improve production efficiency.

[0022] According to some embodiments of the present invention, controlling the first rubbing plate and the second rubbing plate to move synchronously along the first direction includes the following steps: after the first rubbing plate and the second rubbing plate rub a plurality of core wires apart, controlling the first rubbing plate and the second rubbing plate to move synchronously along the first direction to straighten the rubbed core wires at the end of the multi-core wire bundle.

[0023] Advantageously, the present invention straightens the core wires after spreading them apart, thereby ensuring that the core wires are completely spread out and the straightening effect is ensured, and avoiding entanglement of the core wires that may be caused by synchronous operation.

[0024] According to the second embodiment of the present invention, a core wire twisting device is used to implement the core wire twisting method based on a multi-core wire bundle according to the first embodiment of the present invention, and the core wire twisting device includes: The frame defines a first direction, a second direction, and a third direction that are perpendicular to each other; First washboard; a second washboard, wherein the first washboard and the second washboard are arranged side by side along the second direction, and an end portion of a multi-core wire harness extending along the first direction is accommodated between the first washboard and the second washboard; a loosening drive device for controlling the first and second washboards to move relative to each other along a third direction so as to loosen the multiple core wires at the end of the multi-core wire harness; The straightening drive device is used to control the first and second rubbing plates to move synchronously along the first direction to straighten the core wires at the end of the multi-core wire harness.

[0025] The core wire twisting device according to the embodiment of the present invention has at least the following beneficial effects: 1. The present invention provides a rubbing drive device to control the first rubbing plate and the second rubbing plate to move relative to each other along the third direction, so as to rub out the multiple core wires at the end of the multi-core wire harness. Thus, the friction force of the first rubbing plate and the second rubbing plate on the core wires of the multi-core wire harness is utilized. When the first rubbing plate and the second rubbing plate move relative to each other along the third direction, the core wires of the multi-core wire harness are driven to move along the third direction, so that the multiple core wires of the multi-core wire harness can be spread out in a flat distribution state, thereby achieving efficient and uniform rubbing of the core wires, avoiding the inconsistency of manual operation, and improving the initial neatness of the core wire spreading.

[0026] 2. The present invention provides a straightening drive device to control the first rubbing plate and the second rubbing plate to move synchronously along the first direction to straighten the core wires at the end of the multi-core wire bundle. Therefore, while the first rubbing plate and the second rubbing plate are rubbing the core wires or after the first rubbing plate and the second rubbing plate are rubbing the core wires, the straightening drive device is used to control the first rubbing plate and the second rubbing plate to move toward the end of the wire bundle along the first direction relative to the multi-core wire bundle, so that the first rubbing plate and the second rubbing plate use the friction force on the core wire of the wire bundle to straighten the core wire, thereby effectively straightening the bent part of the core wire, ensuring that the core wire is straight after the twisting is completed, improving the quality of the core wire dispersion, and improving production efficiency.

[0027] 3. The present invention realizes the synchronous spreading and straightening of the core wire by the core wire twisting equipment through the cooperation of the spreading drive device and the straightening drive device, without the need for additional straightening steps, significantly improving production efficiency and enhancing the quality of the wire harness end.

[0028] According to some embodiments of the present invention, the core wire twisting device also includes a reset device, which includes a paddle and a first power member. The first power member drives the paddle to move along the third direction so that the paddle can paddle the multiple scattered core wires to close the gaps.

[0029] What is beneficial is that: the present invention provides a reset device in the core wire twisting equipment, and the reset device includes a paddle and a first power member. The first power member drives the paddle to move along the third direction so that the paddle can move the multiple scattered core wires into the gap. It can be understood that the paddle moves the core wires into the gap to avoid excessive deviation of the lateral position of the core wires after the multiple core wires are spread out, ensuring that the core wires are tightly and neatly arranged. At the same time, the first power member is used to drive the paddle to move along the third direction, so that the paddle automatically moves the core wires into the gap during the movement process, reducing manual intervention.

[0030] According to some embodiments of the present invention, the core wire rubbing equipment also includes a heating device, which is arranged on the first rubbing board and / or the second rubbing board, and the heating device is used to heat the first rubbing board and / or the second rubbing board so that the first rubbing board and / or the second rubbing board heats and softens the core wire surface.

[0031] What is beneficial is that: the present invention provides a heating device in the core wire twisting equipment, and the heating device is provided on the first twisting plate and / or the second twisting plate. The heating device is used to heat the first twisting plate and / or the second twisting plate so that the first twisting plate and / or the second twisting plate heat and soften the core wire surface. It can be understood that the heating device increases the temperature of the first twisting plate and / or the second twisting plate so that the first twisting plate and / or the second twisting plate simultaneously softens the core wire surface during the process of twisting the core wire straight, making the core wire easier to straighten during the twisting process and reducing bending residue. In addition, the core wire after the core wire surface is heated and softened is straightened and then cooled, which can make the cooled core wire easier to maintain the straightened state, effectively avoiding the core wire from rebounding and bending, thereby improving the straightening effect.

[0040] The following describes a core wire twisting method and device based on a multi-core wire harness according to an embodiment of the present invention with reference to the accompanying drawings.

[0041] The present invention aims to provide embodiments of a core wire twisting method and device based on a multi-core wire harness.

[0042] Reference Figure 1 The first embodiment of the present invention provides a core wire twisting method based on a multi-core wire harness, wherein the multi-core wire harness includes a wire harness body and a plurality of core wires whose shielding layers have been stripped off at the ends of the wire harness, wherein the core wire twisting method includes the following steps: Step S100: extending the end of the multi-core wire harness along a first direction and placing the end between a first washboard 100 and a second washboard 110 arranged side by side along a second direction, wherein the first direction and the second direction are perpendicular to each other.

[0043] Step S200: controlling the first washboard 100 and the second washboard 110 to move relative to each other along a third direction to loosen the multiple core wires at the end of the multi-core wire harness, wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0044] It can be understood that this embodiment controls the relative movement of the first rubbing plate 100 and the second rubbing plate 110 along the third direction by extending the end of the multi-core wire bundle along the first direction and placing it between the first rubbing plate 100 and the second rubbing plate 110 arranged side by side along the second direction. Thus, by utilizing the friction force of the first rubbing plate 100 and the second rubbing plate 110 on the core wire, the first rubbing plate 100 and the second rubbing plate 110 can drive the core wire of the wire bundle to be rubbed to move along the first direction when the first rubbing plate 100 and the second rubbing plate 110 move relative to each other along the first direction, so that the multiple core wires of the wire bundle to be rubbed can be spread out in a flat distribution state, thereby achieving efficient and uniform spreading of the core wires and improving the initial neatness of the spreading of the core wires.

[0045] Step S300: controlling the first washboard 100 and the second washboard 110 to move synchronously along the first direction to straighten the core wires at the end of the multi-core wire harness.

[0046] It can be understood that this embodiment controls the first rubbing board 100 and the second rubbing board 110 to move synchronously along the first direction, thereby utilizing the friction force of the first rubbing board 100 and the second rubbing board 110 on the core wire, and the first rubbing board 100 and the second rubbing board 110 move synchronously along the first direction so as to straighten the bent core wire longitudinally, ensure that the core wire is straight after the rubbing is completed, improve the quality of the core wire spreading, and improve production efficiency.

[0047] This embodiment controls the first rubbing plate 100 and the second rubbing plate 110 to move relative to each other along the third direction, and controls the first rubbing plate 100 and the second rubbing plate 110 to move synchronously along the first direction, thereby straightening the core wire longitudinally while spreading the core wire, thereby solving the problems of core wire bending and poor uniformity in traditional methods, avoiding secondary manual straightening of the core wire, and significantly improving the quality of core wire spreading and production efficiency.

[0048] Reference Figure 2 In some specific embodiments, before step S100, that is, before placing the end of the multi-core wire harness between the first washboard 100 and the second washboard 110, the following steps are also included: Step S010: controlling the first washboard 100 and the second washboard 110 to move away from each other.

[0049] It can be understood that by controlling the first washboard 100 and the second washboard 110 to move away from each other, there is a sufficient gap between the first washboard 100 and the second washboard 110 to place the end of the multi-core wire harness.

[0050] In some specific embodiments, between step S100 and step S200, that is, after placing the end of the multi-core wire harness between the first washboard 100 and the second washboard 110, and controlling the first washboard 100 and the second washboard 110 to move relative to each other along the third direction, the following steps are also included: Step S110 : controlling the first washboard 100 and the second washboard 110 to approach each other so that the first washboard 100 and the second washboard 110 abut against the end of the multi-core wire harness.

[0051] It can be understood that by controlling the first rubbing plate 100 and the second rubbing plate 110 to approach each other, so that the first rubbing plate 100 and the second rubbing plate 110 abut the end of the multi-core wire bundle, preparation is made for the subsequent loosening of the core wires, so that when the first rubbing plate 100 and the second rubbing plate 110 are subsequently controlled to move relative to each other along the third direction, the first rubbing plate 100 and the second rubbing plate 110 can contact the core wires and drive the core wires to spread out.

[0052] Reference Figure 3 In some specific embodiments, the core wire twisting method further includes the following steps: S210 : During the process of loosening the core thread, the first rubbing plate 100 and the second rubbing plate 110 are controlled to approach each other along the second direction, so that the first rubbing plate 100 and the second rubbing plate 110 are kept in contact with the core thread.

[0053] It can be understood that when the multiple core wires at the end of the multi-core wire harness are in a tangled state, the diameter of the end of the multi-core wire harness is large. In the process of the core wires being rubbed out, the height of the end of the multi-core wire harness along the second obstacle will gradually decrease. By controlling the first rubbing plate 100 and the second rubbing plate 110 to approach each other along the second direction in the process of rubbing out the core wires, the first rubbing plate 100 and the second rubbing plate 110 can continuously reduce the distance between them in the process of rubbing out the core wires, thereby maintaining the contact with the core wires, avoiding the distance between the first rubbing plate 100 and the second rubbing plate 110 being too large, resulting in the first rubbing plate 100 and the second rubbing plate 110 being unable to fully rub out the core wires, and thus, helping to ensure the rubbing effect of the core wires.

[0054] Reference Figure 4 In some specific embodiments, the core wire twisting method further includes the following steps: S310: During the process of straightening the core wires, the core wires at the ends of the multi-core wire harness are heated.

[0055] It can be understood that by heating the core wire to soften the core wire surface, the core wire is easier to straighten during the straightening process, reducing residual bending. In addition, the core wire after the core wire surface is heated and softened is straightened and then cooled, which makes it easier for the cooled core wire to maintain the straightened state, effectively avoiding the core wire from rebounding and bending, thereby improving the straightening effect.

[0056] In some specific embodiments, the core wire twisting method further includes the following steps: S400: After the core threads are spread out, the spread core threads are moved to close the gaps between the core threads.

[0057] This embodiment moves the scattered core wires to close the gaps between the multiple core wires after the core wires are twisted apart. Thus, the core wires are actively moved to close the gaps after the core wires are twisted apart, thereby avoiding excessive lateral deviation of the core wires after the multiple core wires are spread out and ensuring that the core wires are tightly and neatly arranged.

[0058] Furthermore, moving the scattered core wires includes the following steps: moving the core wires from one side of the core wire spreading direction toward the axis of the end portion of the multi-core wire harness.

[0059] This embodiment moves the core wires toward the axis of the end of the multi-core wire bundle from one side of the core wire spreading direction, thereby allowing the spread core wires to move toward the axis of the end of the multi-core wire bundle and preventing the core wires from being bent outward.

[0060] Reference Figure 5 Specifically, step S400 may be between step S200 and step S300.

[0061] Reference Figure 6 In another embodiment, step S400 may also be performed after step S300.

[0062] In some specific embodiments, controlling the first rubbing plate 100 and the second rubbing plate 110 to move synchronously along the first direction includes the following steps: while the first rubbing plate 100 and the second rubbing plate 110 rub out multiple core wires, controlling the first rubbing plate 100 and the second rubbing plate 110 to move synchronously along the first direction to synchronously rub out and straighten the core wires at the ends of the multi-core wire bundle.

[0063] It can be understood that, in this embodiment, the core wire is straightened while being spread out, so that the spreading and straightening are performed simultaneously, which can shorten the process time and improve production efficiency.

[0064] In other embodiments, controlling the first rubbing plate 100 and the second rubbing plate 110 to move synchronously along the first direction includes the following steps: after the first rubbing plate 100 and the second rubbing plate 110 rub out multiple core wires, controlling the first rubbing plate 100 and the second rubbing plate 110 to move synchronously along the first direction to straighten the rubbed core wires at the end of the multi-core wire bundle.

[0065] It can be understood that this embodiment helps to ensure that the core wires are completely spread out and the straightening effect is ensured by straightening the core wires after spreading them out, and avoids the entanglement of the core wires that may be caused by synchronous operation.

[0066] Reference Figure 7 The core wire twisting device of the second embodiment of the present invention is used to implement the core wire twisting method based on a multi-core wire bundle of the first embodiment of the present invention. The core wire twisting device includes a frame 120, a first twisting plate 100, a second twisting plate 110, a twisting drive device 130, a twisting straight drive device 140, a reset device 150 and a heating device 180.

[0067] The rack 120 defines a first direction, a second direction, and a third direction that are perpendicular to each other.

[0068] The first and second washboards 100 and 110 are arranged side by side along the second direction, and the end portion of the multi-core wire harness extending along the first direction is accommodated between the first and second washboards 100 and 110 .

[0069] Reference Figure 8As for the unraveling driving device 130, the unraveling driving device 130 is used to control the first rubbing plate 100 and the second rubbing plate 110 to move relative to each other along the third direction to unravel the multiple core wires at the end of the multi-core wire harness.

[0070] In this embodiment, a spreading drive device 130 is provided to control the first rubbing plate 100 and the second rubbing plate 110 to move relative to each other along the third direction, so as to spread out the multiple core wires at the end of the multi-core wire harness. Thus, the friction force of the first rubbing plate 100 and the second rubbing plate 110 on the core wires of the multi-core wire harness is utilized. When the first rubbing plate 100 and the second rubbing plate 110 move relative to each other along the third direction, the core wires of the multi-core wire harness are driven to move along the third direction, so that the multiple core wires of the multi-core wire harness can be spread out in a flat distribution state, thereby achieving efficient and uniform spreading of the core wires, avoiding the inconsistency of manual operation, and improving the initial neatness of the spreading of the core wires.

[0071] In some specific embodiments, the scrubbing driving device 130 includes a first linear module 190 , and the first linear module 190 is used to drive the first scrubbing plate 100 to move along the third direction.

[0072] It can be understood that the use of the first linear module 190 to precisely control the movement of the first rubbing plate 100 along the third direction enhances the stability and controllability of the rubbing process, avoids the core wire dislocation or excessive friction caused by manual operation in traditional methods, thereby ensuring that the core wire is spread more evenly, reducing the risk of core wire damage or breakage, and at the same time, improving the rubbing efficiency.

In addition, the core wire after the core wire surface is heated and softened is cooled after straightening, which can make the cooled core wire easier to maintain the straightened state, effectively avoiding the core wire from rebounding and bending, thereby improving the straightening effect.

[0100] Specifically, the heating device 180 can be configured as an electric heating rod, and the first washboard 100 and / or the second washboard 110 are provided with mounting holes for mounting the electric heating rod, so that the electric heating rod can uniformly heat the first washboard 100 and / or the second washboard 110 .
