Abstract
Description
Technical Field
[0001] This application relates to the technical field of electric vehicle wiring installation, and more particularly to an automatic conduit-threading device for electric vehicle wiring harnesses. Background Technology
[0002] In the construction system of electric vehicle electronic components, electronic wiring harnesses play a crucial role. They are connection circuit components constructed by crimping copper stamped contact terminals (i.e., connectors) with wires and cables, then encasing them in an external plastic insulation or a metal shell for protection, ultimately forming a bundled wiring harness. To properly secure the wiring harness and prevent it from becoming tangled and intertwined due to a lack of effective separation, the wires are typically stranded and threaded into a corrugated tube, thus achieving effective protection for the electronic wiring harness.
[0003] However, most current wire harness installation equipment uses separate positioning methods for the wire harness and the corrugated tube. In practice, to prevent the wire harness from slipping out of the corrugated tube, a common practice is to use an openable ring to position and manage it. However, this traditional method has significant drawbacks: for wire harnesses of different diameters, the ring size needs frequent adjustments, which undoubtedly reduces the efficiency of the installation process. Summary of the Invention

[0011] In one embodiment of this application, an auxiliary roller is provided below the second bridge, and the auxiliary roller is movably mounted on the equipment frame.
[0012] In one embodiment of this application, the side roller is arranged in an hourglass shape.
[0013] Compared with the prior art, the beneficial effects of this application are: 1.

[0017] The following describes in detail embodiments of the present application, examples of which 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 intended to be used to explain the present application, and should not be construed as limiting the present application.
[0018] The automatic conduit-threading device for electric vehicle wiring harnesses according to embodiments of this application will now be described with reference to the accompanying drawings.
[0019] like Figures 1-7 As shown, the electric vehicle wiring harness automatic conduit insertion device of this application embodiment may include a device frame 10 and a guide component 20, a sorting mechanism 30 and a conveying mechanism disposed on the device frame 10.
[0020] The guide assembly 20 may include a first guide bridge 201 and a second guide bridge 202 connected vertically by a connecting arm 203. The first guide bridge 201 has a notch 2011, and one end of the second guide bridge 202 has a flared part 2021, which can flare the opening of the bellows 90.
[0021] It should be noted that the corrugated pipe 90 passes under the second bridge 202 described in this embodiment, and the wire harness 80 passes over the first bridge 201 described in this embodiment.
[0022] The sorting mechanism 30 may include a spiral coil 302 and a first driving member 301. The first driving member 301 is disposed between the first guide bridge 201 and the second guide bridge 202. One end of the spiral coil 302 is connected to the first driving member 301, and the other end of the spiral coil 302 passes through a notch 2011 and is located on the first guide bridge 201. A wire harness channel 3021 is formed on the inner side of the spiral coil 302. The spiral coil 302 is inclined and its upper end faces the direction of the conveying mechanism. The first driving member 301 may include an outer sleeve 3011, an inner sleeve 3012 disposed inside the outer sleeve 3011, and a telescopic driving member 3013. The output end of the telescopic driving member 3013 is movably connected to one end of the inner sleeve 3012, and the other end of the inner sleeve 3012 is fixedly sleeved on the outside of the spiral coil 302. The inner sleeve 3012 is threadedly connected to the outer sleeve 3011.
[0023] The conveying mechanism may include a mounting base 401, two symmetrically arranged conveying modules 402, and a second drive unit 403. The mounting base 401 is located on one side of the equipment frame 10, and the second guide bridge 202 and the mounting base 401 are respectively located on both sides of the flared member 2021. The two conveying modules 402 are mounted on the mounting base 401 via a relative moving member 50. Each conveying module 402 may include a perpendicular bottom roller 4021 and a side roller 4022. The side roller 4022 is located above the bottom roller 4021 and is hourglass-shaped, capable of lifting and lowering the corrugated pipe 90. Regarding the fit, the two bottom rollers 4021 are movably connected by a linkage component 60. The linkage component 60 may include an inner core 601 and an outer core 602 that are slidably nested together. The inner core 601 and the outer core 602 are rigidly connected to the corresponding bottom rollers 4021, and they are respectively configured as matching polygonal structures. When the two bottom rollers 4021 undergo relative displacement, the overlapping area of the inner core 601 and the outer core 602 changes accordingly. At the same time, due to their polygonal matching characteristics, they have a self-locking function in the rotation direction, which can ensure that they always maintain synchronous rotation during the movement.
[0024] It should be noted that the spiral coil 302 described in this embodiment is a spring-like spiral coil 302, and its material can be high-density plastic with a certain degree of elastic deformation capability, so that the inner diameter of the wire harness channel 3021 can be automatically and flexibly adjusted according to the size of the wire harness 80 passing through. This feature eliminates the cumbersome wire harness channel 3021 adjustment process in traditional equipment and significantly improves the efficiency of conduit threading operations.
[0025] Furthermore, the spiral coil 302 is angled, with its upper end facing the conveying mechanism. This unique design allows the spiral coil 302 to easily wind the wire harness 80 on the first bridge 201. When the spiral coil 302 runs and winds around the outside of the wire harness 80, and one end of the wire harness 80 is inserted into the bellows 90, the wire harness 80 can smoothly pass through the wire harness channel 3021 during its conveyance with the bellows 90, thus achieving the function of organizing the wire harness 80. More importantly, when the conveying angle of the wire harness 80 changes, the spiral coil 302 can always remain tightly wound around the outside of the wire harness 80, continuously performing its organizing function and ensuring the orderliness of the wire harness 80 during the conveyance process.
[0026] It should be noted that the relative moving component 50 described in this embodiment can be a bidirectional cylinder, etc. This component can precisely control the two conveying modules 402 to move closer or further apart, thereby flexibly adjusting the distance between the two side rollers 4022. This design allows the equipment to flexibly adjust the clamping state according to different sizes of corrugated pipes 90 and wire harnesses 80, achieving wide applicability. Moreover, under the action of the linkage component 60, this adjustment process will not cause any interference to the stable operation of the conveying module 402, ensuring the efficiency and reliability of the entire pipe threading operation.
[0027] It should be noted that the first driving component 301 described in this embodiment is responsible for controlling the rotation and movement of the spiral coil 302. Specifically, the telescopic driving component 3013 described in this embodiment can be a cylinder, telescopic motor, etc. Through the action of the telescopic driving component 3013, the inner sleeve 3012 can move linearly relative to the outer sleeve 3011. Since the inner sleeve 3012 and the outer sleeve 3011 are connected by a thread, during the linear movement of the inner sleeve 3012, it will generate a corresponding rotational motion inside the outer sleeve 3011. This unique structure allows the spiral coil 302 to move linearly while rotating. Based on this characteristic, the operator can flexibly adjust the limiting state of the spiral coil 302 and the wire harness 80 through the first driving component 301, easily control the wire harness 80 on the first guide bridge 201 to enter and exit the wire harness channel 3021, realize convenient wire harness 80 loading and unloading operations, and greatly simplify the operation process.
[0028] A corrugated pipe channel 4023 is formed between the two conveying modules 402. An auxiliary roller 70 is provided below the second bridge 202. The auxiliary roller 70 is movably mounted on the equipment frame 10 and can assist in limiting the corrugated pipe 90 passing through the corrugated pipe channel 4023. The second drive unit 403 is connected to the two conveying modules 402 respectively. The second driving component 403 may include a motor 4031, two housings 4032, two bevel gear sets 4033, and two linkage rollers 4034. The two housings 4032 are respectively mounted on corresponding mounting bases 401. The two linkage rollers 4034 are respectively movably mounted inside the corresponding housings 4032. The linkage rollers 4034 are connected to the adjacent side rollers 4022 via a synchronous belt. The linkage rollers 4034 are connected to the adjacent bottom rollers 4021 via a bevel gear set 4033. The bevel gear set 4033 may include two bevel gears respectively connected to the linkage rollers 4034 and the bottom rollers 4021. The motor 4031 is connected to one of the linkage rollers 4034.
[0029] It should be noted that the second drive unit 403 described in this embodiment is responsible for controlling the operation of the two conveying modules 402. Its working principle is that the motor 4031 drives the connected linkage roller 4034 to rotate. This linkage roller 4034 drives the corresponding side roller 4022 to rotate synchronously via a synchronous belt. Simultaneously, the bevel gear set 4033 drives the corresponding bottom roller 4021 to rotate synchronously. Under the coordinated action of the linkage component 60, the bottom roller 4021 of the other conveying module 402 rotates accordingly, and the side rollers 4022 of the other conveying module 402 also achieve synchronous rotation under the linkage of the synchronous belt, the linkage roller 4034, and the bevel gear set 4033. Ultimately, the two side rollers 4022 and the two bottom rollers 4021 operate synchronously, jointly completing the task of conveying the bellows 90.
[0030] Specifically, in actual operation, when it is necessary to thread the wiring harness 80 of an electric vehicle through a conduit, the operator first passes the first end of the corrugated tube 90 through the gap between the auxiliary roller 70 and the second guide bridge 202. Then, the opening of the corrugated tube 90 is fitted over the outside of the flared part 2021 and placed stably on the two bottom rollers 4021. Subsequently, the wiring harness 80 is introduced from the first guide bridge 201, and the portion above the bottom rollers 4021 is inserted into the corrugated tube 90. Afterwards, the two conveyor modules 402 are moved closer together by the relative moving component 50, so that the two side rollers 4022 are tightly pressed against both sides of the corrugated tube 90. During this process, the wiring harness 80 is inserted from the first end of the spiral coil 302 into the wiring harness channel 3021, and the spiral coil 302 is rotated and moved towards the first guide bridge 201 by the first driving component 301. During the rotation of the spiral coil 302, it can automatically and tightly wind around the outside of the wire harness 80, thereby effectively organizing and limiting the wire harness 80.
[0031] After completing the above operations, the operator starts the motor 4031, which drives the connected linkage roller 4034 to rotate. Under the coordinated action of the synchronous belt, bevel gear set 4033, and linkage assembly 60, the two side rollers 4022 and the two bottom rollers 4021 rotate synchronously, jointly driving the corrugated pipe 90 forward. During the transmission of the corrugated pipe 90, the wire harness 80 bound by it also moves synchronously. At this time, the wire harness 80, after being tidied by the spiral coil 302, can smoothly enter the flared corrugated pipe 90, thus completing a stable and efficient pipe threading operation.
[0032] In summary, the automatic wiring harness tube-threading device for electric vehicles according to the embodiments of this application has a spiral coil that can not only flexibly wind and separate from the wiring harness, but also automatically adapt and adjust according to the actual diameter of the limited wiring harness, which greatly improves the efficiency and quality of tube-threading operations.
