[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides a coating machine impregnation adjustment mechanism for wire harness assemblies, such as... Figure 1-5 As shown, it includes a housing 1, an impregnation chamber 11 and a drying chamber 12 opened inside the housing 1, the upper ends of the impregnation chamber 11 and the drying chamber 12 are connected, an inlet and an outlet are opened on the housing 1, and multiple sets of wire harness bodies 13 are slidably connected inside the housing 1.

[0032] Two positioning rods 2 are connected to the inner wall of the impregnation chamber 11, and each wire harness body 13 is attached to the outer wall of the two positioning rods 2.

[0033] Each wire harness body 13 has two sets of collar parts 3 symmetrically slidably connected to its outer wall. The impregnation chamber 11 is equipped with a drive mechanism 4, which is used to push the two sets of collar parts 3 to move towards each other.

[0034] An S-shaped hot air pipe 5 is installed inside the drying chamber 12. Multiple air outlets 51 are evenly spaced on the S-shaped hot air pipe 5. A hot air blower is installed on the outer wall of the housing 1, and the port of the hot air blower is connected to the end of the S-shaped hot air pipe 5. By setting a positioning rod 2 in the impregnation chamber 11, the wire harness body 13 can be stably limited to prevent it from shifting and shaking during the impregnation process. The two sets of collar parts 3, together with the drive mechanism 4, can move in opposite directions, which can flexibly adjust the impregnation operation to meet the needs of different wire harness bodies 13 for impregnation range and glue layer thickness, thereby improving the impregnation adaptability. At the same time, the S-shaped hot air pipe 5 and multiple air outlets 51 in the drying chamber 12 can evenly deliver the hot air from the hot air blower to ensure that the wire harness body 13 is dried evenly and thoroughly after impregnation, thus improving the overall quality and efficiency of wire harness assembly coating and impregnation.

[0035] like Figure 3 As shown, the collar component 3 includes an application collar 31 and a fixing rod 32;

[0036] Each wire harness body 13 has an applicator collar 31 attached to its outer wall, and each applicator collar 31 is connected to the other by a fixing rod 32. The collar component 3 adopts the structure of applicator collar 31 and fixing rod 32. The applicator collar 31 is attached to the outer wall of the wire harness body 13 and can be applied to the impregnation area precisely. The fixing rod 32 connects multiple applicator collars 31 into a whole, ensuring the synchronization and consistency of the impregnation operation of multiple wire harness bodies 13, making the impregnation process more stable and improving the impregnation effect during batch processing.

[0037] like Figure 3 As shown, the drive mechanism 4 includes an electric actuator, a side rod 41, a connecting rod 42, and a balancer 43;

[0038] An electric actuator is installed on the housing 1. Two side rods 41 are symmetrically connected to the lower end of the electric actuator. Each side rod 41 is symmetrically rotatably connected to two connecting rods 42. The other end of each connecting rod 42 is rotatably connected to a corresponding fixed rod 32. The electric actuator of the drive mechanism 4 drives the collar 3 to move through the side rods 41 and connecting rods 42, forming a stable transmission structure. The extension and retraction of the electric actuator can precisely control the movement distance of the collar 3, realizing precise control of the impregnation adjustment.

[0039] like Figure 3 As shown, the balancing component 43 includes a sliding rod 431 and a sliding sleeve 432;

[0040] Two sliding rods 431 are symmetrically connected to the inner wall of the impregnation chamber 11. Two sliding sleeves 432 are symmetrically slidably connected to each sliding rod 431. Each sliding sleeve 432 is connected to the side wall of the corresponding collar 3. The sliding rods 431 and sliding sleeves 432 of the balance component 43 slide in cooperation, providing guidance and support for the movement of the collar 3. This effectively prevents the collar 3 from tilting or shifting during movement, ensuring that the coating collar 31 always fits stably against the wire harness body 13, ensuring the stability of the impregnation adjustment process, and further improving the uniformity of impregnation.

[0041] like Figure 3 and Figure 4 As shown, multiple scraper sleeves 6 are connected to the inner wall of the impregnation chamber 11. Each scraper sleeve 6 is connected to the inner wall of the impregnation chamber 11 by a crossbar 61. The scraper sleeves 6 in the impregnation chamber 11 are fixed by the crossbar 61, which can scrape off excess glue from the surface of the wire harness body 13, reduce glue layer accumulation, and make the glue layer thickness more uniform. This not only improves the appearance quality of the wire harness body 13, but also avoids the adverse effects of excess glue on subsequent drying and assembly processes, and indirectly helps to optimize the impregnation effect.

[0042] like Figure 1 and Figure 3 As shown, multiple rotating rings 7 are equidistantly connected to the inner walls of both the inlet and outlet; these rings can position the incoming and outgoing wire harness bodies 13, effectively protect the delicate wire harnesses, reduce product scrap rate, and improve production qualification rate.

[0043] like Figure 2 and Figure 3 As shown, multiple friction sleeves 8 are connected to the inner wall of the drying chamber 12. Each friction sleeve 8 is connected to the inner wall of the drying chamber 12 by a crossbar 81. The friction sleeves 8 in the drying chamber 12 are fixed by the crossbar 81. When the wire harness body 13 moves, the friction sleeves 8 can be combed to prevent the wire harness from getting tangled. At the same time, the auxiliary hot air can fully contact the wire harness body 13 to accelerate the drying speed of the adhesive layer, improve the drying efficiency and effect, and ensure the curing quality of the adhesive layer.

[0044] Working principle: The main body 13 of the wire harness enters the housing 1 through the feed port. The multiple rotating rings 7 on the inner wall of the feed port play a positioning role for the main body 13 of the wire harness. After entering the housing 1, the main body 13 of the wire harness first enters the impregnation chamber 11 and is attached to the outer wall of the two positioning rods 2. The positioning rods 2 have good limiting effect on it, ensuring that its position is stable during the impregnation process.

[0045] During the impregnation process, the electric push rod in the drive mechanism 4 is activated, which drives the two side rods 41 symmetrically connected at the lower end to move. The two connecting rods 42 symmetrically connected to each side rod 41 move accordingly. Since the other end of the connecting rod 42 is rotatably connected to the fixed rod 32 of the collar 3, it will push the collar 3 to move. The coating collar 31 of the collar 3 is attached to the outer wall of the wire harness body 13. Under the action of the drive mechanism 4, the coating collars 31 of the two sets of collars 3 move towards each other. By controlling the extension and retraction of the electric push rod, the moving distance of the coating collar 31 can be adjusted, thereby adjusting the impregnation range and the thickness of the adhesive layer, realizing the impregnation adjustment. At the same time, the balance component 43 ensures the stability of the adjustment process. The sliding rod 431 on the inner wall of the impregnation chamber 11 slides and engages with the sliding sleeve 432 connected to the side wall of the collar 3, so that the coating collar 31 impregnates the wire harness body 13 evenly.

[0046] After impregnation, the wire harness body 13 continues to move, passing through multiple scraper sleeves 6 on the inner wall of the impregnation chamber 11. The scraper sleeves 6 are connected to the inner wall of the impregnation chamber 11 through a crossbar 61, which can scrape off excess glue from the surface of the wire harness body 13, further ensuring the quality of impregnation. This also indirectly assists in adjusting the impregnation effect.

[0047] Subsequently, the wire harness body 13 enters the drying chamber 12. The hot air blower on the outer wall of the chamber 1 operates, and hot air is delivered through the S-shaped hot air pipe 5. The hot air is evenly blown onto the wire harness body 13 through multiple air outlets 51 on the S-shaped hot air pipe 5 to dry it. Multiple friction sleeves 8 on the inner wall of the drying chamber 12 are fixed by crossbar 81, which play a role in combing and assisting drying when the wire harness body 13 moves. Finally, the wire harness body 13 is sent out from the discharge port. The rotating ring 7 on the inner wall of the discharge port reduces friction during the sending process.

[0048] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
