[0028] At present, the wiring harness process for automotive wiring harnesses is mainly operated manually or by semi-automatic machines. The operator or machine arranges multiple automotive wiring harnesses into bundles, and then manually or mechanically puts heat shrink tubing on the arranged automotive wiring harnesses.

[0029] However, the arrangement order of multiple vehicle wiring harnesses before wiring is relatively random. When the wiring harnesses are subsequently plugged into terminals, the order of multiple vehicle wiring harnesses in the wiring harnesses needs to be rechecked and sorted out, which reduces the production efficiency of the vehicle wiring harnesses.

[0030] In order to solve the technical problem, the present invention provides a vehicle wiring harness production device and method.

[0031] See also Figure 1 and Figure 2 In one embodiment of the present invention, the vehicle wiring harness production device includes a clamping mechanism 100 and a heating mechanism 300. The clamping mechanism 100 is provided with a threading gap 101 for multiple vehicle wiring harnesses to extend into. The periphery of the clamping mechanism 100 is provided with multiple clamping structures 200. The multiple clamping structures 200 are used to respectively clamp the parts of the multiple vehicle wiring harnesses arranged outside the threading gap 101; the heating mechanism 300 is arranged in the threading gap 101, the heating mechanism 300 is sleeved on the outside of the heat shrink tube 400, the heat shrink tube 400 is sleeved on the outside of the multiple vehicle wiring harnesses in the threading gap 101, and the heating mechanism 300 is used to heat the heat shrink tube 400 to sleeve the multiple vehicle wiring harnesses.

[0032] Specifically, the wire clamping mechanism 100 is provided with a threading gap 101 for multiple vehicle wiring harnesses to extend into. A plurality of clamping structures 200 are provided around the wire clamping mechanism 100. The function of the clamping structures 200 is to respectively clamp the portions of the multiple vehicle wiring harnesses that are located outside the threading gap 101. The portion of the vehicle wiring harness that is located outside the threading gap 101, i.e., the heat shrink tube 400, is fixed by the clamping structure 200, thereby ensuring the arrangement order of the vehicle wiring harness in the threading gap 101 and avoiding the randomness of the arrangement of the vehicle wiring harness. This is beneficial to the subsequent terminal plugging operation and improves the overall production efficiency of the vehicle wiring harness.

[0033] The heating mechanism 300 is disposed in the threading gap 101 and is sleeved outside the heat shrink tube 400. The heat shrink tube 400 is sleeved outside the multiple vehicle wiring harnesses in the threading gap 101. The function of the heating mechanism 300 is to heat the heat shrink tube 400 to shrink it, thereby tightly bundling the multiple vehicle wiring harnesses together. Compared with manual operation, the production efficiency and product quality of the vehicle wiring harness are further improved.

[0034] More specifically, in the actual production process, the operator first inserts one end of a plurality of vehicle wiring harnesses into the heat shrink tube 400 in the threading gap 101 of the clamping mechanism 100 in sequence, and fixes the outer portion thereof by the corresponding clamping structure 200. Then, the heating mechanism 300 is started to heat the heat shrink tube 400. The heat shrink tube 400 shrinks due to the heat, tightly wraps the vehicle wiring harness, and forms a stable vehicle wiring harness assembly. Finally, the vehicle wiring harness assembly is taken out of the clamping mechanism 100, and the entire wiring process is completed.

[0035] In the technical solution provided by the present invention, through the cooperation of the wire clamping mechanism 100 and the heating mechanism 300, the wire clamping mechanism 100 has a plurality of clamping structures 200, each of which is used to fix a portion of a vehicle wiring harness outside the threading gap 101, thereby ensuring the arrangement order of the vehicle wiring harness inside the threading gap 101, and making the sheathed wires of multiple vehicle wiring harnesses have a fixed arrangement order in the mass production process, which not only eliminates the common randomness and errors in manual operation, but also provides convenience for subsequent terminal plugging operations, thereby improving the production efficiency of the vehicle wiring harness. In addition, the heating mechanism 300 is directly sleeved on the outside of the heat shrink tube 400, and the heat shrink tube 400 covers the outside of the multiple vehicle wiring harnesses arranged in a fixed order. When the heating mechanism 300 is started, the heat shrink tube 400 is uniformly heated and shrunk, and the multiple vehicle wiring harnesses are tightly bundled together, further accelerating the production speed of the vehicle wiring harness and improving the product quality of the vehicle wiring harness.

[0036] Please continue reading Figure 1 and Figure 2 , and see Figure 3In an embodiment of the present invention, the wire clamping mechanism 100 includes two wire clamping assemblies 110 , the two wire clamping assemblies 110 are arranged at an interval, a threading gap 101 is formed between the two wire clamping assemblies 110 , and a plurality of clamping structures 200 are arranged on the periphery of each wire clamping assembly 110 .

[0037] Specifically, the spacing between the two clamping assemblies 110 defines the width of the threading gap 101, and the operator can adjust the distance between the two clamping assemblies 110 to accommodate vehicle wiring harnesses of different lengths. The multiple clamping structures 200 on the periphery of each clamping assembly 110 are used to fix the vehicle wiring harness passing through the threading gap 101, providing tension for the multiple vehicle wiring harnesses passing through the threading gap 101, ensuring that the multiple vehicle wiring harnesses remain stable and orderly during the wiring process, thereby avoiding the problem of multiple vehicle wiring harnesses being entangled or misaligned during the production process.

[0038] Please continue reading Figures 1 to 3 , and see Figure 4 In an embodiment of the present invention, the clamping assembly 110 includes a clamping disc 111 and a plurality of protruding teeth 112 . The plurality of protruding teeth 112 are installed on the clamping disc 111 at intervals along the circumference of the clamping disc 111 , and a clamping structure 200 is installed between two adjacent protruding teeth 112 .

[0039] It should be noted that the axial direction of the clamping disc 111 is the extending direction of the threading gap 101 .

[0040] Specifically, the clamping disc 111, as the main body of the clamping assembly 110, provides an installation base for the protruding teeth 112 and the clamping structure 200. By installing a plurality of protruding teeth 112 at intervals on the circumference of the clamping disc 111, a plurality of vehicle wiring harnesses can be separated and arranged in a plurality of independent parts, and each part is clamped and fixed by the clamping structure 200 between two adjacent protruding teeth 112. Not only can it adapt to vehicle wiring harnesses of different diameters and quantities, but it can also ensure that each section of the vehicle wiring harness is fixed accordingly, thereby improving the stability of the multiple vehicle wiring harness sheaths.

[0041] In the actual production process, when the vehicle wiring harness passes through the threading gap 101 of the clamping assembly 110, the vehicle wiring harness will contact the protruding teeth 112 on the clamping disc 111 in turn. The protruding teeth 112 can play a role in preliminarily separating and guiding the vehicle wiring harness, so that the vehicle wiring harness can smoothly enter the clamping structure 200 between two adjacent protruding teeth 112. Once the vehicle wiring harness enters the clamping structure 200, the clamping structure 200 applies appropriate clamping force to the vehicle wiring harness to ensure that the vehicle wiring harness maintains a stable position and arrangement order in the subsequent production process. The risk of problems such as displacement or entanglement of the vehicle wiring harness during the production process is reduced, providing a reliable foundation for subsequent terminal plugging, welding and other processes.

[0042] Please continue reading Figure 4 In an embodiment of the present invention, the clamping structure 200 includes two elastic members 210, which are arranged at intervals along the radial direction of the clamping disc 111, and the two elastic members 210 are both installed on the same convex tooth 112, and the two elastic members 210 are arranged close to each other along the circumference of the clamping disc 111 in a direction away from the convex tooth 112, and the part of the vehicle wiring harness arranged outside the threading gap 101 is clamped between the two elastic members 210.

[0043] It should be noted that the elastic member 210 is an elastic rubber ring.

[0044] Specifically, by arranging two elastic members 210 radially spaced apart on the same convex tooth 112, a V-shaped clamping space can be formed. When the vehicle wiring harness contacts the convex tooth 112, the vehicle wiring harness will be guided into this V-shaped clamping space. As the vehicle wiring harness continues to advance, the two elastic members 210 will gradually move closer together under the action of elastic deformation, and eventually clamp the vehicle wiring harness therebetween. The progressive clamping method of the elastic member 210 can not only adapt to vehicle wiring harnesses of different diameters, but also apply a uniform and appropriate clamping force to the vehicle wiring harness during the clamping process, thereby avoiding damage to the vehicle wiring harness.

[0045] In the actual production process, when the vehicle wiring harness passes through the threading gap 101 of the clamping assembly 110, the vehicle wiring harness will first contact the protruding teeth 112 and be guided by the protruding teeth 112 to the V-shaped clamping space between the two elastic members 210. As the vehicle wiring harness continues to advance, the two elastic members 210 will be elastically deformed under the pressure of the vehicle wiring harness and gradually move closer, and finally firmly clamp the vehicle wiring harness therebetween. This clamping state will be maintained until the vehicle wiring harness completely passes through the clamping assembly 110 and enters the next process.

[0046] Please continue reading Figures 1 to 3 In an embodiment of the present invention, the wire clamping assembly 110 also includes a mounting seat 113 and a rotating shaft 114. The rotating shaft 114 extends along the threading gap 101. The rotating shaft 114 is installed on the mounting seat 113. The wire clamping disc 111 is coaxially arranged with the rotating shaft 114, and the wire clamping disc 111 is rotatably installed on the mounting seat 113 through the rotating shaft 114.

[0047] Specifically, the clamping disc 111 can rotate by itself through the mounting seat 113 and the rotating shaft 114. The rotating shaft 114 extends along the threading gap 101, providing support and guidance for the rotation of the clamping disc 111; and the mounting seat 113 provides a stable installation base for the rotating shaft 114. The clamping disc 111 is coaxially arranged with the rotating shaft 114, and is rotatably mounted on the mounting seat 113 through the rotating shaft 114, so that the clamping disc 111 can rotate freely around its axis under the support of the rotating shaft 114, so that the clamping assembly 110 can flexibly adjust the angle and position of the clamping disc 111 according to production requirements, so as to adapt to different vehicle wiring harness introduction directions and angles.

[0048] In the actual production process, when multiple vehicle wiring harnesses enter the threading gap 101 of the clamping assembly 110 from different directions, the clamping disc 111 can be rotated to make the protruding teeth 112 and the clamping structure 200 thereon adapt to the feeding direction of the vehicle wiring harness. In this way, no matter from which angle the vehicle wiring harness enters, it can be accurately guided by a single protruding tooth 112 and reliably clamped by the corresponding clamping structure 200. At the same time, by adjusting the rotation angle of the clamping disc 111, the arrangement and distribution of the vehicle wiring harnesses in the threading gap 101 can also be optimized, thereby improving the space utilization and neatness of the vehicle wiring harnesses.

[0049] In an optional embodiment, the rotating shaft 114 can be connected to a driving device to realize automatic rotation of the clamping disc 111. The driving device can be a motor, a cylinder or other power source. By controlling the operation of the driving device, the rotation angle and speed of the clamping disc 111 can be adjusted to realize intelligent control of the clamping assembly 110.

[0050] In another optional embodiment, by arranging the mounting seat 113 outside the threading gap 101, the mounting positions of the rotating shaft 114 and the clamping disc 111 can be separated from the threading gap 101. In this way, the rotation of the rotating shaft 114 and the clamping disc 111 will not interfere with the passage of the vehicle wiring harness in the threading gap 101, ensuring that the vehicle wiring harness can smoothly pass through the clamping assembly 110 and be inserted into the heat shrink tube 400.

[0051] There are multiple mounting seats 113. The multiple mounting seats 113 are respectively located on both sides of the threading gap 101, which not only facilitates the assembly and maintenance of the mounting seats 113, but also can flexibly adjust the position and size of the mounting seats 113 according to actual needs, further improving the versatility and adaptability of the clamping assembly 110.

[0052] Please continue reading Figures 1 to 4In an embodiment of the present invention, the convex tooth 112 is recessed inward along the radial direction of the clamping disc 111 on one side away from the clamping disc 111 to form an assembly groove 102 with a notch facing outward. A belt 500 is provided on the outer sleeve of each clamping disc 111. The belt 500 is limitedly matched with the assembly groove 102 of multiple convex teeth 112. The two clamping discs 111 are respectively connected to the driving shaft 600 through two belts 500. The driving shaft 600 is arranged outside the threading gap 101 and extends along the threading gap 101. The driving shaft 600 is connected to an external first driving member 700. The first driving member 700 is used to drive the two belts 500 to respectively drive the two clamping discs 111 to rotate.

[0053] Specifically, by providing the assembly groove 102 with the notch facing outward on the convex tooth 112, the belt 500 can be sleeved on the outside of the clamping disc 111, and the belt 500 can be limitedly matched with the assembly groove 102 of each convex tooth 112 to form a stable belt 500 transmission structure. When the driving shaft 600 rotates under the drive of the first driving member 700, the two clamping discs 111 can be synchronously driven to rotate at the same speed and direction through the two belts 500. Not only does it ensure that the convex teeth 112 and the clamping structure 200 on the two clamping discs 111 always maintain the same position and state, but it also improves the clamping stability and reliability of the clamping assembly 110 on the vehicle wiring harness.

[0054] In the actual production process, when the first driving member 700 is started, the driving shaft 600 starts to rotate, and the two clamping discs 111 are synchronously driven to rotate through the two belts 500. Since the two clamping discs 111 rotate at the same speed and direction, the protruding teeth 112 and the clamping structure 200 thereon will also move synchronously, applying uniform clamping force and tensioning force to the vehicle wiring harness. The reliability of clamping the vehicle wiring harness can be improved, the arrangement order of multiple vehicle wiring harnesses can be ensured, and the vehicle wiring harnesses can be prevented from loosening or slipping, thereby improving the production yield of the vehicle wiring harnesses.

[0055] In an optional embodiment, the first driving member 700 may be a motor or other rotating power source, and through connection with the driving shaft 600, the rotation speed of the driving shaft 600 may be controlled to realize automatic control of the rotation of the clamping disc 111. At the same time, by providing a tensioning device on the belt 500, such as a tensioning wheel or a spring, the tension of the belt 500 may be automatically adjusted to compensate for the elongation or relaxation of the belt 500 during long-term use, thereby ensuring the stability and reliability of the transmission.

[0056] Please continue reading Figure 1 and Figure 2 , and see Figure 6In an embodiment of the present invention, the heating mechanism 300 includes a heating seat 310 and a heat supply pipe 320. The heating seat 310 is formed with a heating groove 301 for accommodating the heat shrink tube 400. The heating groove 301 extends along the threading gap 101. A heating channel is formed in the heating seat 310. The groove wall of the heating groove 301 is formed with a plurality of heating holes 302 connected to the heating channel. The plurality of heating holes 302 are arranged at intervals along the circumference of the heating groove 301. The heating channel is connected to an external heating device through the heat supply pipe 320.

[0057] Specifically, the heating groove 301 provides a storage space for the heat shrink tube 400, so that the heat shrink tube 400 can be stably placed in the heating seat 310. The heating groove 301 extends along the threading gap 101, ensuring that the heat shrink tube 400 can cover multiple vehicle wiring harnesses in the threading gap 101. A heating channel is set in the heating seat 310, and a heating hole 302 connected to the heating channel is opened on the groove wall of the heating groove 301, so that the heat in the heating channel can be effectively transferred to the heat shrink tube 400. By arranging multiple heating holes 302 at intervals in the circumferential direction of the heating groove 301, the heat shrink tube 400 can be uniformly heated in the circumferential direction, ensuring that the heat shrink tube 400 is heated uniformly at various parts, thereby improving the uniformity and reliability of the shrinkage of the heat shrink tube 400.

[0058] In the actual production process, when the vehicle wiring harness passes through the wire clamp assembly 110 and enters the heat shrink tube 400 in the heating groove 301, the external heating device supplies heat to the heating channel through the heating pipe 320. The heat is transferred to the heat shrink tube 400 through the heating channel and the heating hole 302, so that the heat shrink tube 400 shrinks due to the heat and is tightly wrapped around the outside of multiple vehicle wiring harnesses arranged in a fixed order. Since the heating holes 302 are evenly distributed along the circumference of the heating groove 301, all parts of the heat shrink tube 400 are heated uniformly and can shrink at the same speed and degree to form a uniform and stable vehicle wiring harness assembly. This not only improves the quality and reliability of vehicle wiring harness products, but also reduces the production defect rate caused by uneven shrinkage of the heat shrink tube 400.

[0059] It should be noted that the heating hole 302 can be in different shapes and sizes, such as circular, oval or slit, to accommodate heat shrink tubes 400 of different models and materials. In addition, the heating pipe 320 can be connected to various types of heating devices, such as electric heaters, steam heaters or hot air heaters, to meet different production environments and process requirements.

[0060] Please continue reading Figure 6 In an embodiment of the present invention, an opening 303 communicating with the heating groove 301 is formed on the top of the heating seat 310 , and the area of ​​the opening 303 projected on the heating seat 310 is smaller than the area of ​​the heat shrink tube 400 projected on the heating seat 310 .

[0061] Specifically, an opening 303 communicating with the heating groove 301 is provided on the top of the heating seat 310, so that the heat shrink tube 400 can be conveniently inserted into or taken out of the heating groove 301. At the same time, by adjusting the size of the opening 303 so that its orthographic projection area is smaller than the orthographic projection area of ​​the heat shrink tube 400, it can be ensured that the heat shrink tube 400 is stably accommodated in the heating groove 301 to prevent it from being displaced or falling off during the heating process.

[0062] In the actual production process, when it is necessary to sleeve the vehicle wiring harness, the operator can easily insert the heat shrink tube 400 into the heating groove 301 through the opening 303 on the top of the heating seat 310. Since the size of the opening 303 is smaller than the size of the heat shrink tube 400, the heat shrink tube 400 will be squeezed and expanded by multiple vehicle wiring harnesses after insertion, so that it can be stably accommodated and fixed by the heating groove 301. Subsequently, the heating mechanism 300 starts to work and evenly heats the heat shrink tube 400 through the heating channel and the heating hole 302. After the heat shrink tube 400 shrinks due to the heat and is tightly wrapped around the outside of the vehicle wiring harness, the operator removes the shrunk heat shrink tube 400 from the heating groove 301 through the opening 303 to complete the sleeve process. The entire operation is simple and convenient, without the need for complex loading and unloading mechanisms, which improves production efficiency.

[0063] Please continue reading Figure 1 and Figure 2 , and see Figure 5 In an embodiment of the present invention, the vehicle wiring harness production device also includes a wire feeding mechanism 800, which is arranged on the outside of the wire clamping mechanism 100; the wire feeding mechanism 800 includes a guide plate 810, a slider 820 and a second driving member 830, the guide plate 810 extends along the threading gap 101, the slider 820 is slidably installed on the guide plate 810 along the extension direction of the guide plate 810, the slider 820 is connected to the second driving member 830, and the second driving member 830 is used to drive the slider 820 to push the vehicle wiring harness on the guide plate 810 into the threading gap 101.

[0064] Specifically, the guide plate 810 extends along the threading gap 101, providing guidance and support for the transportation of the vehicle wiring harness. The slider 820 can slide along the extension direction of the guide plate 810 and is connected to the second driving member 830. When the second driving member 830 is started, the slider 820 is driven to move along the guide plate 810 and push the vehicle wiring harness on the guide plate 810 into the threading gap 101. The automated wire feeding method not only reduces the labor intensity of manual operation, but also improves the accuracy and efficiency of the vehicle wiring harness transportation, and provides an automated operation basis for the subsequent clamping and wire sleeve processes.

[0065] In an optional embodiment, after the wire delivery mechanism 800 delivers a vehicle wire harness to a clamping structure 200 of the clamping assembly 110, the first drive member 700 drives the rotating shaft 114 to rotate the clamping disc 111 and switch to another empty clamping structure 200. At this time, the wire delivery mechanism 800 delivers another new vehicle wire harness to the empty clamping structure 200 so that it is clamped and fixed. By repeating this process, multiple vehicle wire harnesses can be evenly distributed around the periphery of the clamping disc 111, so that the vehicle wire harnesses can be arranged and positioned in an orderly manner. This not only improves production efficiency, but also ensures the position accuracy and stability of the vehicle wire harnesses during the subsequent wiring process.

[0066] In another optional embodiment, the top of the guide plate 810 is recessed downward to form a V-shaped groove for guiding each vehicle wiring harness. The V-shaped groove can guide the vehicle wiring harness to accurately enter the heat shrink tube 400 in the threading gap 101 from the clamping structure 200 at the bottom of the clamping assembly 110. When a vehicle wiring harness moves from one clamping assembly 110 to another clamping assembly 110 through the heat shrink tube 400 under the push of the wire conveying mechanism 800, the vehicle wiring harness can be released from the V-shaped groove and made to reach a predetermined position in the heat shrink tube 400 by synchronously rotating the two clamping assemblies 110. The reliability of the vehicle wiring harness transportation is further improved, and the position consistency and stability of multiple vehicle wiring harnesses in the heat shrink tube 400 are ensured.

[0067] Please continue reading Figures 1 to 6 , and see Figure 7 The present invention also provides a method for using a vehicle wiring harness production device, using the vehicle wiring harness production device as described above, and the method for using the vehicle wiring harness production device includes: Step S10, passing the plurality of vehicle wiring harnesses through the threading gap 101 of the wire clamping mechanism 100 in sequence, so that the plurality of vehicle wiring harnesses all pass through the heat shrink tube 400; Step S20, using the plurality of clamping structures 200 to respectively clamp the portions of the plurality of vehicle wiring harnesses disposed outside the threading gap 101; Step S30, starting the heating mechanism 300 to heat the heat shrink tube 400 to shrink the heat-shrink tube 400 and tightly wrap the plurality of vehicle wiring harnesses; Step S40, taking out the plurality of vehicle wiring harnesses that have been wired.

[0068] Specifically, step S10: pass multiple vehicle wiring harnesses through the threading gap 101 of the wire clamping mechanism 100 in sequence, ensuring that each vehicle wiring harness passes through the pre-set heat shrink tube 400. This step utilizes the guiding and positioning functions of the wire clamping mechanism 100 to ensure that the vehicle wiring harness can accurately pass through the heat shrink tube 400, providing the correct initial position for the subsequent heating and shrinking operation. The operator can use the wire feeding mechanism 800 to feed the vehicle wiring harnesses into the threading gap 101 one by one, and guide and fix the vehicle wiring harnesses with the help of the protruding teeth 112 and the clamping structure 200 on the wire clamping assembly 110. The position accuracy of the vehicle wiring harness when passing through the heat shrink tube 400 is ensured, avoiding the occurrence of problems such as entanglement or misalignment of the vehicle wiring harness.

[0069] Step S20: Use multiple clamping structures 200 to clamp the portion of each vehicle wiring harness outside the threading gap 101. In this step, the clamping structure 200 stably fixes the vehicle wiring harness to prevent the vehicle wiring harness from moving during the heating process, thereby ensuring that the heat shrink tube 400 can shrink and wrap each vehicle wiring harness evenly. When the vehicle wiring harness passes through the heat shrink tube 400 and reaches the other side of the clamping assembly 110, the corresponding clamping structure 200 will automatically close and firmly clamp the vehicle wiring harness. This ensures the position stability of the vehicle wiring harness during the subsequent heating process.

[0070] Step S30: Start the heating mechanism 300 to heat the heat shrink tube 400. During the heating process, the heat shrink tube 400 shrinks evenly due to the heat, tightly wrapping multiple vehicle wiring harnesses. In this step, the uniform heating ability of the heating mechanism 300 ensures that the heat shrink tube 400 shrinks evenly over the entire length, avoiding the situation of local over-tightness or over-looseness, and improving the overall quality and appearance of the product. The heating channel and the heating hole 302 allow heat to be evenly transferred to various parts of the heat shrink tube 400. During the heat shrinkage process, the heat shrink tube 400 will gradually adhere to the surface of the vehicle wiring harness to form a tight and uniform coating. This high-quality sheathing effect not only improves the insulation performance and mechanical strength of the vehicle wiring harness, but also provides a good foundation for subsequent connector assembly.

[0071] Step S40: Take out the multiple vehicle wiring harnesses that have been sheathed. After the sheathing is completed, the operator can easily take out the processed vehicle wiring harness from the device for subsequent assembly or inspection. Since the top of the heating seat 310 is provided with an opening 303, and the size of the opening 303 is smaller than the size of the heat shrink tube 400 after shrinkage, the operator only needs to gently pull it to smoothly take out the vehicle wiring harness from the heating groove 301. This improves production efficiency and reduces unnecessary waiting time.
