The main purpose of the coating of electric vehicle wiring harnesses is to protect the wiring harnesses from mechanical damage, moisture erosion, chemical corrosion, and electrical interference, thereby improving the durability and safety of the wiring harnesses. The coating materials of electric vehicle wiring harnesses usually include tapes, heat shrink tubes, corrugated tubes, wear-resistant self-rolling tubes, etc. These materials have good insulation, wear resistance, corrosion resistance, and anti-aging properties, and can effectively protect the wiring harnesses.

[0003] Chinese patent announcement number CN117410035B discloses a wrapping device for automobile wiring harness production, including a tape ring, the inner cavity of the tape ring is fixedly sleeved with a fixed wheel, the inner cavity of the fixed wheel is movably equipped with five adjustment wheels, and the inner cavity tops of the five adjustment wheels are movably equipped with force plates. The present invention effectively avoids the deviation of the wire body and affects the normal tape wrapping work by setting an adjustment wheel, a force plate, a spring, a movable block, an airbag bag, a telescopic rod, and an adjustment pressure plate.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

During the rotation, the debris and dust attached to the outer surface of the wiring harness of the electric vehicle are cleaned, and then it is flipped and rinsed. After the rinsing operation is completed, the moisture attached to the outer surface of the wiring harness of the electric vehicle is dried by the heating and extrusion assembly 6, and the heat shrink tube is put on the outer surface of the wiring harness of the electric vehicle. Then, the wiring harness of the electric vehicle is clamped and fixed again, and the heat shrink tube is heated by the heating and extrusion assembly 6 so that the heat shrink tube can be coated on the outer surface of the wiring harness of the electric vehicle.

[0038] For further information, see Figure 4 and Figure 5 In this embodiment, the conveying mechanism 53 includes two rotating rods 531 rotatably connected to the inner surface of the base 1, the outer surfaces of the two rotating rods 531 are symmetrically fixedly connected with rollers 532, the outer surfaces of the rollers 532 on the same side are commonly wound and connected with cables 534, the left end of the front rotating rod 531 is fixedly connected to a double-axis motor 533 fixedly connected to the base 1, the outer surfaces of the two cables 534 are fixedly connected to sliders 535 slidably connected to the inner surface of the slide groove 51, and the left end output end of the double-axis motor 533 is fixedly connected to the rotating rod 2 536 through a coupling.

[0039] For further information, see Figure 4 , Figure 6 and Figure 7 In this embodiment, the clamping rotation mechanism 54 includes a fixed block 541 fixedly connected to the upper end of the slider 535, the inner surface of the fixed block 541 is rotatably connected to a hollow rod 542, the left end of the hollow rod 542 is fixedly connected to a concave block 543, the lower ends of the two sliders 535 are commonly fixedly connected to an oil tank 544, the inner surface of the hollow rod 542 is rotatably connected to a ring 547, the upper part of the inner surface of the oil tank 544 penetrates and extends to the left end of the ring 547 and is fixedly connected to a connecting pipe 546, the lower end of the connecting pipe 546 is fixedly installed with an oil pump 545, and the inner surface of the connecting pipe 546 is fixedly connected to It is connected to a connecting pipe 2 548, and a solenoid valve 1 549 is fixedly installed at the intersection of the outer surfaces of the connecting pipe 1 546 and the outer surfaces of the connecting pipe 2 548. The flow channels 5410 are symmetrically opened on the upper end of the hollow rod 542, and the inner surfaces of the two flow channels 5410 are slidably connected to piston rods 5411, and the ends of the two piston rods 5411 that are close to each other are fixedly connected to a fixing plate 5413, and the outer surfaces of the two piston rods 5411 are sleeved with springs 1 5412, and the two ends of the two springs 1 5412 are fixedly connected to the piston on the piston rod 5411 and the inner surface of the flow channel 5410 respectively.

[0040] For further information, see Figure 4 , Figure 6 and Figure 7 In this embodiment, a rack 57 is fixedly connected to the inner surface of the concave frame 52 in a symmetrical manner, and a gear 5414 meshing with the rack 57 is fixedly connected to the outer surface of the hollow rod 542.

[0041] During the implementation process, the two ends of the wiring harness of the electric vehicle are placed in the concave block 543, and then the oil pump 545 is started to extract the hydraulic oil in the oil tank 544 into the connecting pipe 546. The hydraulic oil enters the flow channel 5410 through the hollow rod 542, and then pushes the two piston rods 5411 on the concave block 543 to move closer to the middle, and exhausts through the circular hole on the concave block 543. The spring 5412 is in a compressed state, so that the rubber blocks on the two fixing plates 5413 can be tightly attached to the two ends of the wiring harness of the electric vehicle.

[0042] Secondly, after the fixing operation is completed, the right end output end of the dual-axis motor 533 is started to drive the rotating rod 531 located at the front to rotate through the coupling, so that the two rollers 532 rotate, and the cable 534 moves backward under the action of the winding connection, driving the slider 535 to slide on the inner surface of the slide groove 51, so that the wiring harness of the electric vehicle fixed on the concave block 543 moves backward, and when the gear 5414 is engaged with the rack 57, the hollow rod 542 is rotated to flip the wiring harness of the electric vehicle fixed on the concave block 543, which can cooperate with the subsequent comprehensive cleaning operation of the wiring harness of the electric vehicle.

[0043] The hollow rod 542 and the fixed block 541 are rotationally connected, and there is a certain resistance between the two, so that the hollow rod 542 can rotate only after the gear 5414 is meshed with the rack 57.

[0044] For further information, see Figure 4 and Figure 8 In this embodiment, the cleaning structure 55 includes two transmission rods 551 rotatably connected to the inner surface of the concave frame 52, the outer surfaces of the two transmission rods 551 are commonly wound and connected with a cleaning brush 554, the outer surface of the rotating rod 2 536 is commonly fixedly connected with a pulley group 1 552, and the outer surfaces of the two transmission rods 551 are commonly fixedly connected with a pulley group 2 553.

[0045] During the implementation process, the electric vehicle wiring harness is conveyed to the rear through the clamping rotating mechanism 54 and the electric vehicle wiring harness is turned over. At this time, the left end output end of the dual-axis motor 533 is started to drive the rotating rod 2 536 to rotate through the coupling. Under the coordinated transmission action of the pulley group 1 552 and the pulley group 2 553, the cleaning brushes 554 on the two transmission rods 1 551 rotate to clean the dust attached to the outer surface of the electric vehicle wiring harness. The cleaning brush 554 directly contacts the outer surface of the electric vehicle wiring harness by rotating, and can effectively brush off the dust attached to the surface of the electric vehicle wiring harness. Dust, at the same time, the rotation of the electric vehicle wiring harness can be cleaned more comprehensively. It can not only remove the dust on the surface of the wiring harness, but also penetrate the bristles into the gaps and grooves of the wiring harness to clean out the hard-to-reach dirt and dust. This comprehensive cleaning method helps to improve the cleaning quality of the wiring harness, ensuring that its surface and interior are kept clean, and can improve the ability of the heat shrink tube to fit the wiring harness tightly during the subsequent coating process to avoid the formation of gaps or bubbles due to the presence of dust and debris. The tight fit can improve the protective effect of the heat shrink tube, so that it can better protect the wiring harness from damage from the external environment.

[0046] The cleaning brush 554 mentioned above is made of soft material.

[0047] The dual-axis motor 533 mentioned above is a mature driving technology means and equipment in the prior art. In this solution, the couplings on both sides thereof can rotate independently and stop in time after rotating a set number of circles. Its internal structure, connection method and principle will not be elaborated any more.

[0048] For further information, see Figure 3 , Figure 4 and Fig. 9In this embodiment, the flushing mechanism 56 includes a water tank 561 fixedly connected to the lower end of the base 1, the upper inner surface of the water tank 561 penetrates and extends to the inner surface of the concave frame 52 and is fixedly connected to a water pipe 562, the lower end of the water pipe 562 is fixedly connected to a water pump 563, a rectangular groove 564 is opened at the upper end of the base 1, and the lower inner surface of the rectangular groove 564 penetrates and extends to the rear end of the base 1 and is fixedly connected to a sewage pipe 565.

[0049] From the above, it can be seen that the cleaned electric vehicle wiring harness continues to move backward. At this time, the water pump 563 is started to draw water from the water tank 561 into the water pipe 562, and the water is sprayed out through the water pipe 562 and cooperated with the rotation of the electric vehicle wiring harness to perform a comprehensive flushing operation on the outer surface of the electric vehicle wiring harness. The water during the flushing process is discharged from the base 1 through the cooperation of the rectangular groove 564 and the drain pipe 565, which can further clean the debris and dust attached to the outer surface of the electric vehicle wiring harness.

[0050] Embodiment 2: Based on Embodiment 1, this embodiment adds a heating and extrusion component 6 for covering and extruding the electric vehicle wiring harness, so as to achieve the purpose of covering and extruding the electric vehicle wiring harness.

[0051] Specifically, in order to cover and extrude the electric vehicle wiring harness, refer to Figure 4 , Fig.10 and Fig.11 In this embodiment, the heating and extrusion assembly 6 includes a concave frame 61 fixedly connected to the rear portion of the upper end of the base 1, a hot air mechanism 62 is provided at the left end of the base 1, an extrusion mechanism 63 is provided at the upper inner surface of the concave frame 61, and a rack 64 meshing with the gear 5414 is symmetrically fixedly connected to the upper inner surface of the concave frame 61.

[0052] For further information, see Figure 4 and Fig.10 In this embodiment, the hot air mechanism 62 includes a rectangular hole box 621 fixedly connected to the left end of the base 1, a notch plate 622 is fixedly connected to the inner surface of the rectangular hole box 621, a fan blade 623 is rotatably connected to the inner surface of the rectangular hole box 621, the outer surface of the fan blade 623 and the outer surface of the rear transmission rod 551 are jointly fixedly connected with a pulley group 3 624, a heating plate 625 is fixedly installed on the right part of the inner surface of the rectangular hole box 621, a plurality of inclined plates 626 fixedly connected to the right end of the notch plate 622 are fixedly connected to the left end of the heating plate 625, an air outlet pipe 1 627 is fixedly connected to the inner surface of the concave frame 1 52 on the inner surface of the rectangular hole box 621, an air outlet pipe 1 627 is fixedly connected to the inner surface of the concave frame 2 61 on the inner surface of the air outlet pipe 1 627 is fixedly connected to the inner surface of the concave frame 2 61, and an electromagnetic valve 2 629 is fixedly connected to the intersection of the outer surface of the air outlet pipe 1 627 and the outer surface of the air outlet pipe 2 628.

[0053] During the implementation process, after the electric vehicle wiring harness is flushed, the rotation of the transmission rod 551 at the rear is transmitted through the pulley group 3 624, which can drive the fan blade 623 to rotate, and the air is sucked into the inner cavity of the rectangular hole box 621 through the rectangular holes on the rectangular hole box 621, and enters the space formed by the heating plate 625, the notch plate 622 and the rectangular hole box 621 through the notch plate 622 at any time, and the temperature of the air is heated by the heating plate 625. At the same time, under the action of the inclined plate 626, the air form path is extended, so that the air can be blown out through the air outlet pipe 627, and the electric vehicle wiring harness is rotated for drying, so as to remove moisture during the flushing process and avoid affecting the coating quality of the electric vehicle wiring harness during subsequent coating.

[0054] Secondly, after the drying operation is completed, the hydraulic oil in the left concave block 543 is refluxed under the compression reaction force of the spring 1 5412 through the cooperation of the solenoid valve 1 549 and the connecting pipe 2 548. At this time, the fixing plate 5413 in the left concave block 543 no longer fixes the wiring harness of the electric vehicle. The staff can put the heat shrink tube on the wiring harness of the electric vehicle, and then fix the wiring harness again through the fixing plate 5413.

[0055] In addition, when the electric vehicle wiring harness moves backward, the outer surface of the heat shrink tube is heated through the cooperation of the solenoid valve 2 629 and the air outlet pipe 2 628, so that the heat shrink tube can gradually shrink on the outer surface of the electric vehicle wiring harness. At the same time, during the rotation process, the heat shrink tube can be evenly heated. The previous drying can also reduce the temperature difference between the electric vehicle wiring harness and the heat shrink tube, and the thermal stress between the two will also be reduced accordingly, which helps the heat shrink tube to better fit the wiring harness, reduce gaps and bubbles caused by thermal stress, and allow the heat shrink tube to better cover the outer surface of the electric vehicle wiring harness, thereby improving the sealing and quality.

[0056] The solenoid valve 1 549 and the solenoid valve 2 629 mentioned above are both mature control technology means and equipment in the prior art. In this solution, they are used to control the flow direction of liquid or gas, and their internal structure, principle and connection method are not further explained.

[0057] The heating plate 625 mentioned above is a mature heating technology means and equipment in the prior art. In this solution, its heating function is utilized, and its internal structure, principle and connection method are not further explained.

[0058] For further information, see Figure 3 , Figure 4 and Fig.11In this embodiment, the squeezing mechanism 63 includes a concave plate 631 fixedly connected to the upper inner surface of the concave frame 61, a round block rod 635 is slidably connected to the inner surface of the concave plate 631, a lower pressure plate 636 is fixedly connected to the lower end of the round block rod 635, a spring 637 is sleeved on the outer surface of the round block rod 635, and the two ends of the spring 637 are respectively fixedly connected to the round block on the round block rod 635 and the upper end of the concave plate 631, a transmission rod 632 rotatably connected to the concave plate 631 is rotatably connected to the inner surface of the concave frame 61, a pulley group 633 is fixedly connected to the outer surface of the transmission rod 632 and the outer surface of the rotating rod 1 531 located at the rear, a cam 634 is fixedly connected to the middle part of the outer surface of the transmission rod 632, and a placement block 638 is fixedly connected to the middle side of the rear upper end of the base 1.

[0059] During the implementation process, when the wrapped electric vehicle wiring harness continues to move backward to the upper end of the placement block 638, the transmission rod 2 632 rotates under the transmission action of the pulley group 4 633, thereby driving the cam 634 to rotate, so that the cam 634 can intermittently squeeze the round block rod 635, so that the downward movement of the lower pressure plate 636 will cooperate with the rotation of the electric vehicle wiring harness to comprehensively squeeze the electric vehicle wiring harness. The extrusion process can make the various parts of the wiring harness more closely combined to form a unified whole, which helps to improve the overall strength and stability of the wiring harness, so that it can better withstand the pressure and impact of the external environment, and the gaps and bubbles inside the wiring harness can be effectively eliminated, so that the heat dissipation channel of the wiring harness is more unobstructed, thereby improving the heat dissipation performance of the wiring harness and preventing failures or damage caused by overheating.

[0060] The above-mentioned pulley group 1 552, pulley group 2 553, pulley group 3 624 and pulley group 4 633 are all prior art and are composed of two pulleys and a belt.

[0061] Working process: When in use, the two ends of the electric vehicle wiring harness are clamped by the clamping and rotating mechanism 54, and then the electric vehicle wiring harness is rotated while moving backward under the cooperation of the conveying mechanism 53 and the clamping and rotating mechanism 54, and the dust and debris attached to the outer surface of the electric vehicle wiring harness are cleaned by the cleaning structure 55 and the flushing mechanism 56, and the hot air mechanism 62 is used to dry it, and then the heat shrink tube is put on and heated by the hot air mechanism 62, and the heat shrink tube is covered on the outer surface of the electric vehicle wiring harness, and finally the extrusion operation is continued by the extrusion mechanism 63.
