Description
Technical Field
[0001] This utility model relates to the field of automotive wiring harnesses, and in particular to an automotive wiring harness shielding wire conveying mechanism. Background Technology
[0002] The conveying mechanism is an indispensable part of the production of automotive wire harness shielded wires. Its core value lies in ensuring product quality, improving production efficiency, reducing labor costs, and meeting the high reliability standards of the automotive industry. The automotive wire harness shielded wire conveying mechanism is mainly used for the automated conveying and positioning of shielded cables such as high-voltage wire harnesses and signal lines in automotive production lines. It is suitable for processes such as robot wiring and wire harness assembly.
[0003] Existing traditional automotive wiring harness shielding wire conveying mechanisms mostly use open roller transmission, with manual threading and guidance, whereby the wire harness is passed sequentially through multiple guide wheels and traction devices.
[0004] However, in existing open roller conveyor mechanisms, the wire harness may fall off from the side during transport, while the narrow space of enclosed conveyor mechanisms makes it impossible for personnel to enter and thread the wires, requiring the use of external tools. This makes it impossible to quickly wind the wire harness onto the guide wheels, resulting in reduced threading efficiency. Therefore, an automotive wire harness shielded wire conveyor mechanism is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides an automotive wiring harness shielding wire conveying mechanism, which aims to improve the problem in the prior art that the wiring harness cannot be quickly wound onto each set of guide wheels.
[0006] To achieve the above objectives, this utility model adopts the following technical solution: an automotive wiring harness shielding wire conveying mechanism, comprising an outer frame, a motor fixedly connected to the outer wall of the back of the outer frame, a transmission wheel fixedly connected to the output end of the motor, a sliding frame fixedly connected to the top of the outer frame, a movable frame slidably connected to the inner wall of the sliding frame, a follower wheel rotatably connected to the bottom of the movable frame, a threaded rod rotatably connected to the inner wall of the top of the movable frame, a tensioning base fixedly connected to the inner wall of the outer frame, a tensioning rod elastically connected to the inner wall of the bottom of the tensioning base via a compression spring, a tensioning wheel fixedly connected to the top of the tensioning rod, and a guide wheel rotatably connected to the inner wall of the left side of the outer frame.
[0007] As a further description of the above technical solution:
[0008] The outer frame has a guide groove at the front, and a guide rod is slidably connected to the inner wall of the guide groove. A bolt is threaded to the upper outer arc surface of the guide rod, and a handle is fixedly connected to the front end of the guide rod.
[0009] As a further description of the above technical solution:
[0010] The motor end is rotatably connected to the inner wall of the outer frame, and the sliding frame is slidably connected to the inner wall of the outer frame.
[0011] As a further description of the above technical solution:
[0012] The threaded rod is threaded onto the top inner wall of the outer frame.
[0013] As a further description of the above technical solution:
[0014] One end of the compression spring is fixedly connected to the inner wall of the tensioning base, and the other end of the compression spring is fixedly connected to the bottom of the tensioning rod.
[0015] As a further description of the above technical solution:
[0016] The tensioning rod is slidably connected to the inner wall of the tensioning base.
[0017] As a further description of the above technical solution:
[0018] The end of the guide rod contacts the inner wall of the outer frame.
[0019] As a further description of the above technical solution:
[0020] The bottom of the bolt is rotatably connected to the lower inner wall of the guide rod.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the combination of guide groove and split guide rod enables the wire harness winding operation to be completed quickly, which significantly improves the efficiency compared to manual wire threading. The closed structure of the outer frame, combined with the limiting design of the sliding frame, can prevent the wire harness from falling off or foreign objects from entering. At the same time, the closed-loop path design of the guide wheel and tension wheel reduces the noise of wire harness transportation.
[0023] 2. In this utility model, through the cooperation of compression spring and tension wheel, the conveying mechanism can automatically compensate for the tension fluctuation of the wire harness, so that the wire harness always remains taut and avoids tangling or wear caused by slack. The adjustable clamping design of follower wheel and transmission wheel can be adapted to shielded wires of different specifications. Attached Figure Description

[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] Reference Figures 1-3 This utility model provides an embodiment of an automotive wiring harness shielded wire conveying mechanism, including an outer frame 1. The outer frame 1 is used to enclose the transmission wiring harness to prevent it from falling off during transport. A motor 2 is fixedly connected to the outer wall of the back of the outer frame 1. The motor 2 is prior art and will not be described in detail. It is used to drive a transmission wheel 3 to rotate. The output end of the motor 2 is fixedly connected to the transmission wheel 3. The surface of the transmission wheel 3 is made of rubber or hard plastic material and is used to contact the wiring harness, driving it to move through friction. A sliding frame 4 is fixedly connected to the top of the outer frame 1. The sliding frame 4 is used to keep the moving frame 5 vertically stable and to prevent it from tilting or deviating from the top of the transmission wheel 3 due to friction. The moving frame 5 is slidably connected to the inner wall of the sliding frame 4. The moving frame 5 is used as a follower wheel 6. The moving frame 5 provides a rotation origin and support force, and can drive the follower wheel 6 to move up and down. The follower wheel 6 is rotatably connected to the bottom of the moving frame 5. The follower wheel 6 is used to contact the top of the wire harness and provide downward pressure to the wire harness so that the wire harness will not deviate from the top of the transmission wheel 3 during transportation. The inner wall of the top of the moving frame 5 is rotatably connected to a threaded rod 7. The threaded rod 7 is used to be threadedly connected to the outer frame 1. The moving frame 5 is driven to move up and down through the threaded feed. The inner wall of the outer frame 1 is fixedly connected to a tensioning base 8. The tensioning base 8 is provided with two sets of upper and lower opposing ones to provide stable up and down sliding stability for the tensioning rod 10. The end of the motor 2 is rotatably connected to the inner wall of the outer frame 1. The sliding frame 4 is slidably connected to the inner wall of the outer frame 1. The threaded rod 7 is threadedly connected to the inner wall of the top of the outer frame 1.
[0032] Reference Figures 2-4The outer frame 1 has a guide groove 12 at the front, which is set as the track for wire harness transportation. It is used to drive the wire harness to wind around the guide wheel 16, tension wheel 11 and transmission wheel 3 via the guide rod 13. This achieves closed and anti-drop transportation while facilitating manual winding of the wire harness. The guide rod 13 is slidably connected to the inner wall of the guide groove 12. The guide rod 13 is open and divided into upper and lower parts. The top is set with a downward slope and the bottom is set with a flat surface. It is used to clamp wire harnesses of different diameters by bolts 14. The upper outer arc surface of the guide rod 13 is threaded with bolts 14. By rotating the bolts 14, the top and bottom of the guide rod 13 are simultaneously loosened or clamped. The front end of the guide rod 13 is fixedly connected to a handle 15. The handle 15 is used to extend the guide rod 13 to the outside and provide a handle for the operator to hold and move. The end of the guide rod 13 contacts the inner wall of the outer frame 1. The bottom of the bolt 14 is rotatably connected to the lower inner wall of the guide rod 13.
[0033] Reference Figures 1-3 A tensioning rod 10 is elastically connected to the inner wall of the bottom of the tensioning base 8 via a compression spring 9. The tensioning rod 10 slides within the tensioning base 8, providing auxiliary force for the stable up-and-down movement of the tensioning wheel 11. The tensioning wheel 11 is fixedly connected to the top of the tensioning rod 10. The tensioning wheel 11 contacts the wire harness and provides tension to the wire harness through the opposing squeezing force between the compression spring 9 and the tensioning base 8, ensuring that the wire harness remains taut during transport and preventing damage from repeated contact. A guide wheel 16 is rotatably connected to the inner wall of the left side of the outer frame 1. The input end of the wire harness is used to guide the wire harness from various parts to the middle of the outer frame 1. One end of the compression spring 9 is fixedly connected to the inner wall of the tensioning base 8, and the other end of the compression spring 9 is fixedly connected to the bottom of the tensioning rod 10. Through the opposing squeezing force between the compression spring 9 and the tensioning base 8, the tensioning rod 10 always has an upward thrust, thereby giving the tensioning wheel 11 an upward thrust. Through the elasticity of the compression spring 9, an adaptive tension force is provided to the wire harness. The tensioning rod 10 is slidably connected to the inner wall of the tensioning base 8.
[0034] Working principle: After the motor 2 starts, it drives the transmission wheel 3 to rotate. Its rubber or hard plastic surface drives the wire harness to move through friction. At the same time, the moving frame 5 moves up and down through the threaded connection between the threaded rod 7 and the outer frame 1, driving the follower wheel 6 to press down on the wire harness, ensuring that the wire harness is in close contact with the surface of the transmission wheel 3, and avoiding slippage or deviation during conveying. The downward pressure of the follower wheel 6 can be precisely controlled by adjusting the feed amount of the threaded rod 7 to adapt to wire harnesses of different diameters.
[0035] The compression spring 9 inside the tensioning base 8 pushes the tensioning rod 10 upward through opposing extrusion force, so that the tensioning wheel 11 is always in close contact with the wire harness. When the wire harness tension changes, the compression spring 9 can automatically extend and retract to maintain the wire harness in a taut state. When the wire harness becomes loose due to bending during the transportation process, the tensioning wheel 11 moves upward under the action of the spring force to compensate for the looseness and prevent the insulation layer from being damaged due to the wire harness shaking and friction with the components.
[0036] When winding the wire harness, the guide groove 12 provides a preset conveying trajectory for the wire harness. The operator pushes the guide rod 13 to slide in the guide groove 12 through the handle 15, and winds the wire harness onto the guide wheel 16, tension wheel 11 and transmission wheel 3. The guide rod 13 adopts an upper and lower split design, and the rotating bolt 14 can clamp wire harnesses of different diameters.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
