Description

Technical Field

[0001] This utility model relates to the technical field of wire harness production, and in particular to a wire twisting device based on core wire twisting and a wire harness assembly line. Background Technology

[0002] A wire harness, also called a wire bundle, is a whole composed of multiple single-strand core wires twisted or bound together.

[0003] The core wires at the ends of the wire harness need to undergo a series of processing steps. During these processing steps, the core wires at the ends of the wire harness are required to spread out.

[0004] The traditional method for separating the core wires at the end of a wire harness is to manually separate the core wires.

[0005] However, the traditional method of unpacking the core wires has low production efficiency and poor uniformity after unpacking. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a wire twisting device based on core wire twisting, which can twist the core wire, improve the neatness of the twisted core wire, and increase production efficiency.

[0007] This utility model also proposes a wire harness assembly line having the above-mentioned wire twisting device based on core wire twisting.

[0008] According to a first aspect of the present invention, a wire twisting device based on core wire twisting includes:

[0009] The wire-splitting device includes a first wire-splitting mechanism and a second wire-splitting mechanism arranged along a third direction. The first wire-splitting mechanism includes a first splitting plate, and the second wire-splitting mechanism includes a second splitting plate. The end of the wire bundle to be splitting extends along a second direction and is accommodated between the first splitting plate and the second splitting plate. The first splitting plate and the second splitting plate move relative to each other along a first direction to split the core wire of the wire bundle to be splitting.

[0010] The wire twisting device based on core wire twisting according to the embodiments of the present invention has at least the following beneficial effects:

[0011] This invention, through the arrangement of a first and a second twisting mechanism along a third direction in a twisting device, places the end of the wire bundle to be twisted, extending along a second direction, between the first twisting plate of the first twisting mechanism and the second twisting plate of the second twisting mechanism. The first and second twisting plates are then moved relative to each other along a first direction. By utilizing the frictional force of the first and second twisting plates on the core wires of the wire bundle to be twisted, the core wires of the wire bundle to be twisted are moved along the first direction as the first and second twisting plates move relative to each other, allowing the multiple core wires of the wire bundle to be twisted to spread out in a flat distribution. This achieves efficient and uniform twisting of the core wires, avoids inconsistencies from manual operation, and improves the initial neatness of the core wire spreading.

[0012] According to some embodiments of the present invention, the first thread twisting mechanism further includes a first moving component, which is used to drive the first twisting board to move along the first direction;

[0013] And / or, the wire twisting equipment also includes a frame defining a first direction, a second direction, and a third direction that are perpendicular to each other.

[0014] The advantages of this invention are as follows: By including a first moving component in the first twisting mechanism, the first moving component drives the first twisting plate to move along a first direction. It can be understood that by using the first moving component to precisely control the movement of the first twisting plate along the first direction, the stability and controllability of the twisting process are enhanced, avoiding the core wire misalignment or excessive friction caused by manual operation in traditional methods. This ensures that the core wire is spread more evenly, reduces the risk of core wire damage or breakage, and improves the twisting efficiency. In addition, by setting a frame that defines the mutually perpendicular first, second, and third directions, the twisting device can twist the core wire radially, and the straightening device can straighten the core wire axially, avoiding the twisting device and straightening device bending the core wire.

[0015] According to some embodiments of the present invention, the twisting device further includes a second moving component and / or a third moving component, wherein the second moving component is used to drive the first twisting mechanism to move along the third direction, and the third moving component is used to drive the second twisting mechanism to move along the third direction.

[0016] The advantages of this invention are: by setting a second moving component and / or a third moving component in the twisting device, the second moving component is used to drive the first twisting mechanism to move in a third direction, and the third moving component is used to drive the second twisting mechanism to move in a third direction. It can be understood that the second moving component and / or the third moving component can adjust the position of the first twisting mechanism and / or the second twisting mechanism in the third direction. On the one hand, it can adjust the distance between the first twisting plate and the second twisting plate to facilitate the picking and placing of wire harnesses. On the other hand, it can handle wire harnesses of different diameters or types by changing the distance between the first twisting plate and the second twisting plate, improve the versatility of the equipment, and avoid the limitation of wire harness size imposed by traditional fixed twisting plates. Furthermore, adjusting the distance between the first twisting plate and the second twisting plate ensures that the contact pressure between the first twisting plate and the second twisting plate and the wire harness is moderate, preventing the core wire from being crushed or insufficiently spread, thereby improving the neatness and surface quality of the core wire.

[0017] According to some embodiments of the present invention, the rubbing device further includes a reset mechanism, which includes a lever that can limit the movement of the core wire along the first direction.

[0018] The advantages are: by setting a reset mechanism, which includes a lever, the present invention limits the movement of the core wire in the first direction. It can be understood that the reset mechanism constrains the movement of the core wire in the first direction by using the lever, preventing the core wire from spreading out excessively, misaligning, or falling outside the first and second rubbing boards during the tucking process, ensuring that the core wire remains in parallel arrangement and improving the neatness of the core wire arrangement.

[0019] According to some embodiments of the present invention, the reset mechanism further includes a first power member, which is used to drive the paddle to move along the first direction so that the paddle moves the core wires to close the arrangement gap.

[0020] The advantages of this invention are: by setting a first power component, which is used to drive the paddle to move along a first direction, so that the paddle can move the core wires to close the gaps in the arrangement, it can be understood that the first power component drives the paddle to move along the first direction, which can actively move the core wires to close the gaps in the arrangement, dynamically adjust the core wire spacing, and make the core wires tighter and straighter. It is especially suitable for high-density wire harnesses, reducing bending and uneven gaps.

[0021] According to some embodiments of the present invention, two first thread twisting mechanisms are provided, and the two first thread twisting mechanisms are arranged along the first direction, and two corresponding second thread twisting mechanisms are provided.

[0022] The advantage of this invention is that by setting up two first twisting mechanisms arranged along a first direction, and correspondingly setting up two second twisting mechanisms, it is possible to process two wire bundles or process both ends of a wire bundle at the same time, thereby improving production efficiency.

[0023] According to some embodiments of the present invention, the yarn twisting device further includes a straightening device, which is used to drive the yarn spreading device to move along the second direction so that the first twisting plate and the second twisting plate cooperate to straighten the core yarn.

[0024] The advantages of this invention are: by setting up a straightening device, which drives the spreading device to move along the second direction, it can be understood that while or after the spreading device is spreading the core wire, the straightening device drives the spreading device to move along the second direction, so that the first and second rubbing plates can move towards the end of the wire bundle in the second direction, so that the first and second rubbing plates can straighten the core wire by using the friction force on the core wire of the wire bundle. This effectively straightens the bent part of the core wire, ensures that the core wire is straight after the wire spreading equipment is completed, improves the quality of the spread core wire, and improves production efficiency.

[0025] According to some embodiments of the present invention, the first rubbing board and / or the second rubbing board are provided with a heating device, which is used to heat the first rubbing board and / or the second rubbing board so as to heat and soften the outer sheath of the core wire.

[0026] The advantages of this invention are: by providing a heating device on the first and / or second rubbing boards, the heating device is used to heat the first and / or second rubbing boards to soften the outer sheath of the core wire. It can be understood that by heating the core wire to soften the outer sheath, the core wire is easier to separate and straighten during the twisting and straightening process, reducing bending residue. In addition, after the core wire outer sheath is softened by heating, it is cooled after twisting and straightening, which makes it easier for the cooled core wire to maintain the state after twisting and straightening, effectively preventing the core wire from rebounding and bending.

[0027] According to some embodiments of the present invention, the straightening device includes a movable frame and a driving mechanism. The spreading device is disposed on the movable frame, and the movable frame is slidably disposed on the frame along the second direction. The driving mechanism is used to drive the movable frame to slide along the second direction.

[0028] The advantages of this invention are: by including a moving frame and a driving mechanism in the straightening device, the tucking device is set on the moving frame, the moving frame is slidably set on the frame along the second direction, and the driving mechanism is used to drive the moving frame to slide along the second direction. It can be understood that the moving frame, as a bearing platform, makes the tucking device move more smoothly, effectively straightens the core wire bending, and improves the straightness.

[0029] According to some embodiments of the present invention, the driving mechanism includes a first screw and a first motor. The first screw extends along the second direction, is rotatably connected to the frame, is threadedly connected to the movable frame, and the first motor drives the first screw to rotate.

[0030] The advantages of this invention are: by making the drive mechanism include a first screw and a first motor, the first screw extends along the second direction, the first screw is rotatably connected to the frame, the first screw is threadedly connected to the moving frame, and the first motor drives the first screw to rotate. It can be understood that the screw drive ensures that the moving distance and speed of the moving frame are adjustable, avoiding overshoot or undershoot, and making the core wire straightening more accurate.

[0031] According to a second aspect of the present invention, a wire harness assembly line includes a wire twisting device based on core wire twisting according to a first aspect of the present invention.

[0032] The wire harness assembly line according to the embodiments of the present utility model has at least the following beneficial effects:

[0033] 1. This utility model, by setting a first twisting mechanism and a second twisting mechanism arranged along a third direction in the twisting device, places the end of the wire bundle to be twisted, which extends along a second direction, between the first twisting plate of the first twisting mechanism and the second twisting plate of the second twisting mechanism, and moves the first twisting plate and the second twisting plate relative to each other along a first direction. Thus, by utilizing the frictional force of the first twisting plate and the second twisting plate on the core wire of the wire bundle to be twisted, when the first twisting plate and the second twisting plate move relative to each other along the first direction, they drive the core wire of the wire bundle to be twisted to move along the first direction, so that the multiple core wires of the wire bundle to be twisted can be spread out into a flat distribution state. Thus, the core wires are twisted out efficiently and evenly, avoiding the inconsistency of manual operation and improving the initial neatness of the core wires.

[0034] 2. This utility model, by setting a straightening device on the frame, is used to drive the spreading device to move along the second direction. It can be understood that, at the same time or after the spreading device spreads the core wire, the straightening device drives the spreading device to move along the second direction, so that the first and second rubbing plates can move towards the end of the wire bundle in the second direction, so that the first and second rubbing plates can straighten the core wire by using the friction force on the core wire of the wire bundle. In this way, the bent part of the core wire is effectively straightened, ensuring that the core wire is straight after the wire is finished by the wire twisting equipment, improving the quality of the spread core wire, and enabling the spread core wire to be directly crimped to the terminal, thereby improving production efficiency.

[0035] 3. In this embodiment, the combination of the tucking device and the straightening device enables the simultaneous tucking and straightening of the core wire, eliminating the need for an additional straightening step, significantly improving production efficiency, and enhancing the quality of the wire harness ends, thereby improving the quality of subsequent crimped terminals.

[0036] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0046] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This invention describes a wire twisting device and a wire harness assembly line based on core wire twisting according to embodiments of the present invention.

[0047] This utility model aims to provide embodiments of a wire twisting device and a wire harness assembly line based on core wire twisting.

[0048] In this embodiment, the wire harness assembly line mainly includes a wire twisting device based on core wire twisting.

[0049] Reference Figure 1 The wire twisting device based on core wire twisting according to this utility model embodiment includes a frame 100, a twisting device 110, and a straightening device 160.

[0050] For rack 100, rack 100 is defined by a first direction, a second direction and a third direction that are perpendicular to each other.

[0051] It is understood that, in this embodiment, by setting up a frame 100, which defines a first direction, a second direction, and a third direction that are perpendicular to each other, the tucking device 110 can tucking the core wire radially, and the straightening device 160 can straighten the core wire axially, thereby preventing the tucking device 110 and the straightening device 160 from bending the core wire.

[0052] Reference Figure 1 and Figure 2 For the tucking device 110, the tucking device 110 includes a first tucking mechanism 120 and a second tucking mechanism 130 arranged along a third direction. The first tucking mechanism 120 includes a first tucking plate 140, and the second tucking mechanism 130 includes a second tucking plate 150. The end of the wire bundle to be tucking extends along a second direction is accommodated between the first tucking plate 140 and the second tucking plate 150. The first tucking plate 140 and the second tucking plate 150 move relative to each other along a first direction to tucking the core wire of the wire bundle to be tucking.

[0053] In this embodiment, by setting a first twisting mechanism 120 and a second twisting mechanism 130 arranged along a third direction in the twisting device 110, the end of the wire bundle to be twisted, extending along a second direction, is placed between the first twisting plate 140 of the first twisting mechanism 120 and the second twisting plate 150 of the second twisting mechanism 130, and the first twisting plate 140 and the second twisting plate 150 are moved relative to each other along a first direction. Thus, by utilizing the frictional force of the first twisting plate 140 and the second twisting plate 150 on the core wire of the wire bundle to be twisted, when the first twisting plate 140 and the second twisting plate 150 move relative to each other along the first direction, the core wire of the wire bundle to be twisted is driven to move along the first direction, so that the multiple core wires of the wire bundle to be twisted can be spread out and laid out in a flat distribution state. Thus, the core wires are twisted out efficiently and evenly, avoiding the inconsistency of manual operation and improving the initial neatness of the core wires.

[0054] It should be explained that a clamp can be used to fix the main body of the wire harness to be twisted, and the end of the wire harness to be twisted can be suspended outside the clamp in order to fix the main body of the wire harness to be twisted and prevent the wire twisting equipment from dragging the main body of the wire harness to be twisted and shifting its position when twisting the end of the wire harness.

[0055] In some specific embodiments, the first thread twisting mechanism 120 further includes a first moving component 170, which is used to drive the first thread twisting board 140 to move along a first direction.

[0056] Understandably, by using the first moving component 170 to precisely control the movement of the first rubbing board 140 along the first direction, the stability and controllability of the rubbing process are enhanced, avoiding the core wire misalignment or excessive friction caused by manual operation in traditional methods. This ensures that the core wires are spread out more evenly, reduces the risk of core wire damage or breakage, and improves the rubbing efficiency.

[0057] Specifically, the first moving component 170 may include a first slider, a first rack, and a second motor. A first washboard 140 is disposed on the first slider. The first slider is slidably disposed on the output end of the second moving component 180 or the straightening device 160 described below along a first direction. The first rack extends along the first direction and is fixed on the output end of the second moving component 180 or the straightening device 160. The second motor is fixed on the first slider. The output end of the second motor is provided with a first gear. The first gear and the first rack mesh and drive each other so that the second motor drives the first slider to move along the first direction.

[0058] In other embodiments, the first moving component 170 may include a first slider, a second screw, and a second motor. A first rubbing plate 140 is disposed on the first slider. The first slider is slidably disposed on the output end of the second moving component 180 or the straightening device 160 described below in a first direction. The second screw extends in the first direction and is rotatably connected to the output end of the second moving component 180 or the straightening device 160 described below. The second screw is threadedly connected to the first slider. The second motor is used to drive the second screw to rotate, thereby driving the first slider to move in the first direction.

[0059] In other embodiments, the first moving component 170 may include a first slider and a first cylinder, the first rubbing plate 140 is disposed on the first slider, the first slider is slidably disposed on the output end of the second moving component 180 or the straightening device 160 described below along a first direction, the first cylinder is fixed on the output end of the second moving component 180 or the straightening device 160, and the first cylinder is used to drive the first slider to move along the first direction.

[0060] In some specific embodiments, the twisting device 110 further includes a second moving component 180 and / or a third moving component 190, wherein the second moving component 180 is used to drive the first twisting mechanism 120 to move in a third direction, and the third moving component 190 is used to drive the second twisting mechanism 130 to move in a third direction.

[0061] Understandably, the second moving component 180 and / or the third moving component 190 can adjust the position of the first twisting mechanism 120 and / or the second twisting mechanism 130 along a third direction. On the one hand, it can adjust the distance between the first twisting plate 140 and the second twisting plate 150 to facilitate the picking and placing of wire harnesses. On the other hand, it can handle wire harnesses of different diameters or types by changing the distance between the first twisting plate 140 and the second twisting plate 150, thereby improving the equipment's versatility and avoiding the limitation of wire harness size imposed by traditional fixed twisting plates. Furthermore, adjusting the distance between the first twisting plate 140 and the second twisting plate 150 ensures that the contact pressure between the first twisting plate 140 and the second twisting plate 150 and the wire harness is moderate, preventing the core wires from being crushed or insufficiently spread, thereby improving the neatness and surface quality of the core wires.

[0062] Specifically, the second moving component 180 may include a first moving base and a first cylinder, the first thread twisting mechanism 120 is disposed on the first moving base, the first moving base is slidably disposed on the straightening device 160, the first cylinder is fixed on the straightening device 160, and the first cylinder is used to drive the first thread twisting mechanism 120 to move in a third direction.

[0064] In some specific embodiments, the first rubbing board 140 and / or the second rubbing board 150 are provided with a heating device 200, which is used to heat the first rubbing board 140 and / or the second rubbing board 150 so that the first rubbing board 140 and / or the second rubbing board 150 heat and soften the core wire sheath.

[0065] It is understandable that heating the core wire softens its outer sheath, making it easier to separate and straighten the core wire during the twisting and straightening process, reducing residual bending. In addition, after the core wire's outer sheath is softened by heating, it is cooled after twisting and straightening, which makes it easier for the cooled core wire to maintain its twisted and straightened state, effectively preventing the core wire from rebounding and bending.

[0066] Specifically, the heating device 200 can be configured as an electric heating rod, and the first rubbing plate 140 and / or the second rubbing plate 150 can be provided with mounting holes for mounting the electric heating rod, so that the electric heating rod can uniformly heat the first rubbing plate 140 and / or the second rubbing plate 150.

[0067] In some specific embodiments, the rubbing device 110 further includes a reset mechanism 210, which includes a paddle 220 for limiting the movement of the core wire along a first direction.

[0068] Understandably, the reset mechanism 210 constrains the movement of the core wire in the first direction through the paddle 220, preventing the core wire from spreading out excessively, becoming misaligned, or falling outside the first and second washboards 140 and 150 during the tucking process, ensuring that the core wire remains in parallel arrangement and improving the neatness of the core wire arrangement.

[0069] Furthermore, the reset mechanism 210 also includes a first power member 230, which is used to drive the paddle 220 to move along a first direction so that the paddle 220 can move the core wires to close the arrangement gap.

[0070] Understandably, the first power component 230 drives the paddle 220 to move along the first direction, which can actively move the core wires to close the arrangement gaps and dynamically adjust the core wire spacing, making the core wires tighter and straighter. This is especially suitable for high-density wire harnesses, reducing bending and uneven gaps.

[0071] In some specific embodiments, the first power element 230 may be located at the output end of the third moving component 190.

[0072] Specifically, the first power component 230 can be configured as a third cylinder, which is located at the output end of the third moving component 190. The third cylinder drives the paddle 220 to move along the first direction.

[0073] In other embodiments, the first power component 230 may also be configured as a third motor and a third screw. The third motor is fixed to the output end of the third moving component 190, the third screw is rotatably connected to the output end of the third moving component 190, and the third screw is threadedly connected to the paddle 220. The third motor drives the third screw to rotate, thereby driving the paddle 220 to move along the first direction.

[0074] In some specific embodiments, two first twisting mechanisms 120 are provided, and the two first twisting mechanisms 120 are arranged along a first direction. Two second twisting mechanisms 130 are provided accordingly, so that two wire harnesses can be processed at the same time or both ends of the wire harness can be processed at the same time, thereby improving production efficiency.

[0075] Specifically, both first thread twisting mechanisms 120 can be located at the output end of the second moving component 180, and both second thread twisting mechanisms 130 can be located at the output end of the third moving component 190.

[0076] In some specific embodiments, the paddle 220 may be provided with two limiting parts, which are used to limit the core wires on the two first twisting mechanisms 120 respectively.

[0077] Reference Figure 3 The straightening device 160 is mounted on the frame 100 and is used to drive the shredding device 110 to move along the second direction to straighten the core wire.

[0078] Understandably, while or after the core wire is being shredded by the shredding device 110, the straightening device 160 moves the shredding device 110 along the second direction, so that the first shredding plate 140 and the second shredding plate 150 can move towards the end of the wire bundle in the second direction, so that the first shredding plate 140 and the second shredding plate 150 can straighten the core wire by using the friction force on the core wire of the wire bundle. This effectively straightens the bent part of the core wire, ensures that the core wire is straight after the wire twisting equipment is completed, improves the quality of the core wire spreading, and improves production efficiency.

[0079] In some specific embodiments, the straightening device 160 includes a movable frame 240 and a driving mechanism 250. The spreading device 110 is disposed on the movable frame 240. The movable frame 240 is slidably disposed on the frame 100 along the second direction. The driving mechanism 250 is used to drive the movable frame 240 to slide along the second direction.

[0080] Understandably, the movable frame 240 serves as a support platform, enabling the tucking device 110 to move more smoothly, effectively straightening the core wire and improving straightness.

[0081] Specifically, the drive mechanism 250 includes a first screw 260 and a first motor 270. The first screw 260 extends along a second direction and is rotatably connected to the frame 100. The first screw 260 is threadedly connected to the movable frame 240, and the first motor 270 drives the first screw 260 to rotate.

[0082] Understandably, the screw drive ensures that the moving distance and speed of the moving frame 240 are adjustable, avoiding overshoot or undershoot, and making the core wire straightening more precise.

[0083] In this embodiment, the combination of the tucking device 110 and the straightening device 160 enables the simultaneous tucking and straightening of the core wire, eliminating the need for additional straightening steps, significantly improving production efficiency, and enhancing the quality of the wire harness ends, thereby improving the quality of subsequent crimped terminals.
