[0002] With the development of electric vehicles, precision electronics, and high-voltage energy, wire harness connections face challenges such as higher voltage, stricter protection, and more complex materials. Thermofusion welding is a specialized process technology that uses precise heat to melt the insulation material of wire harnesses, combined with pressure, to simultaneously achieve reliable conductor connection and insulation layer sealing protection. Compared with traditional wire harness connection methods, the process is simpler and the reliability is much higher.

[0003] When welding multiple wire harnesses simultaneously during operation, it is difficult to locate the welding points, causing misalignment of the welding points. During welding, some insulation layers are not heated to a molten state and cannot adhere to the conductor, resulting in a decrease in wire harness performance.

[0004] Therefore, it is necessary to provide a wire harness insulation layer hot melt welding device to solve the above-mentioned technical problems. Utility Model Content

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] First Embodiment

[0031] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 A wire harness insulation layer hot melt welding device includes: a workbench 1, a welding assembly 11 installed on one side of the workbench 1, a welding head 12 installed on the welding assembly 11, a first push rod 13 installed on the side of the workbench 1 symmetrical to the welding assembly 11, a movable plate 2 installed at the output end of the first push rod 13, and a limit groove 21 opened at one end of the movable plate 2 and on the workbench 1;

[0032] A limiting structure 3 is installed on the movable plate 2 and is located on one side of the limiting groove 21;

[0033] Positioning structure 4 is inserted and installed in the limiting groove 21, and the positioning structure 4 is used to position the wire harness;

[0034] During operation, the positioning structure 4 is inserted into the limiting groove 21 to position the moving plate 2. Multiple wire harnesses are passed through the limiting structure 3 so that one end of the wire harness at the welding position is tightly fitted with the positioning structure 4. After placement, the wire harness is positioned by the limiting structure 3 to prevent displacement and shaking during welding. During welding, the positioning structure 4 is pulled out, the first push rod 13 is activated to move the moving plate 2, and the welding position of the wire harness is moved to below the welding head 12. The welding assembly 11 is activated to move the welding head 12 to weld the wire harness. The positioning structure 4 positions the welding part to keep the welding parts of multiple wire harnesses aligned, avoiding misalignment of the welding position which would prevent the insulation layer from adhering to the conductor and cause a decrease in wire harness performance.

[0035] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 6 The limiting structure 3 includes a support frame 31, a second push rod 32, a mounting plate 33, an upper pressure block 34, and a lower pressure block 35. The support frame 31 is mounted on the movable plate 2. The second push rod 32 is mounted on the top of the support frame 31. The mounting plate 33 is mounted on the output end of the second push rod 32. Multiple upper pressure blocks 34 are mounted at equal intervals on the mounting plate 33. Multiple lower pressure blocks 35 are mounted at equal intervals below the upper pressure blocks 34 on the movable plate 2. Each upper pressure block 34 and each lower pressure block 35 forms a group. The upper pressure block 34 and the lower pressure block 35 are used to limit the wire harness.

[0036] During operation, multiple wire harnesses are passed between the upper pressure block 34 and the lower pressure block 35 and then placed on the lower pressure block 35 in sequence. After placement, the second push rod 32 is activated, and the output end drives the mounting plate 33 and multiple upper pressure blocks 34 to move downward. Each set of upper pressure blocks 34 and lower pressure blocks 35 limits one wire harness, placing multiple wire harnesses at intervals. This also prevents the wire harnesses from shifting during welding, which could lead to insufficient welding and affect the performance of the wire harnesses.

[0037] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 5 The positioning structure 4 includes a limiting plate 41 and a positioning plate 42. The limiting plate 41 is inserted into the limiting groove 21, and the positioning plate 42 is installed on one side of the limiting plate 41.

[0038] During operation, the limiting plate 41 is inserted into the limiting groove 21 to position the moving plate 2 and the Xining. After the wire harness passes through the upper pressure block 34 and the lower pressure block 35, the welding positions of multiple wire harnesses are tightly fitted with the positioning plate 42 to position the welding positions of the wire harnesses. This ensures that the welding positions of multiple wire harnesses are kept aligned, preventing misalignment of the welding positions from causing the insulation layer to fail to adhere to the conductor and affecting the performance of the wire harness.

[0039] Please refer to the following: Figure 1 , Figure 2 and Figure 5 The surface of the movable plate 2 is also provided with welding points 22, which are located between the limiting groove 21 and the support frame 31;

[0040] During operation, after placing multiple wire harnesses on the lower pressure block 35, the welding position of the wire harnesses is maintained on the welding point 22. When the moving plate 2 moves below the welding head 12, the welding point 22 is located directly below the welding head 12, so that the welding is performed at the welding point 22, avoiding the welding head 12 from affecting other positions of the moving plate 2.

[0041] Please refer to the following: Figure 2 and Figure 4 The workbench 1 is also provided with a sliding groove 14, and the movable plate 2 is slidably installed in the sliding groove 14;

[0042] When the first push rod 13 pushes the moving plate 2 to move during operation, the moving plate 2 slides in the slide groove 14 and is limited by the slide groove 14 to prevent the moving plate 2 from deviating.

[0043] Second Embodiment

[0044] Please refer to the following: Figure 3 , Figure 4 and Figure 5 The movable plate 2 is also equipped with multiple buckles 23 at equal intervals, and the multiple buckles 23 correspond to the multiple pressing blocks 35.

[0045] In this embodiment, after placing the wire harness on the lower pressure block 35, the other end of the wire harness is placed in the corresponding buckle 23 to prevent the wire harness from getting tangled and to facilitate removal after welding.

[0046] Please refer to the reference again. Figure 1 , Figure 2 , Figure 3 and Figure 4 Rubber pads are provided on the surfaces of the multiple upper pressure blocks 34, the multiple lower pressure blocks 35 and the multiple buckles 23, and the rubber pads are used to protect the wire harness;

[0047] During operation, the wire harness is limited and protected by rubber pads to prevent damage to the wire harness surface due to friction.

[0048] The working principle of the wire harness insulation layer hot melt welding device provided by this utility model is as follows:

[0049] Before welding, insert the limiting plate 41 into the limiting groove 21. After passing the wire harness through the upper pressure block 34 and the lower pressure block 35, ensure that one end of each wire harness at the welding position is tightly fitted to the positioning plate 42 and placed on the welding point 22, keeping the welding position flush. This achieves the effect of positioning the welding position and prevents misalignment, which could cause the insulation layer to fail to adhere to the conductor and affect the performance of the wire harness. After placement, activate the second push rod 32. The output end drives the mounting plate 33 and multiple upper pressure blocks 34 downward to limit the wire harness and prevent displacement or shaking during welding. During welding, pull out the limiting plate 41, activate the first push rod 13 to move the moving plate 2, and move the welding point 22 below the welding head 12. Activate the welding assembly 11 to move the welding head 12 to weld the wire harness. Set the clips 23. After placing the wire harness on the lower pressure block 35, place the other end of the wire harness in the corresponding clip 23 to prevent the wire harness from getting tangled and to facilitate removal after welding.

[0050] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
