Description

Technical Field

[0001] The present application relates to the field of wire harness winding and unwinding, and particularly to a wire harness winding and unwinding device. Background Art

[0002] Copper-silver alloy wire harness is a relatively common alloy wire. Its electrical conductivity and thermal conductivity are better than those of most metal wires, so it is widely used in the power field; during the production process of copper-silver alloy wire harness, in order to facilitate the processing operation of the wire harness, a winding and unwinding device is usually required to unwind and wind the wire harness. At this time, the wire harness can pass through a series of devices to perform multiple processes in sequence to complete the processing of the wire harness. These processes include, for example, a cleaning process, a coating process, and a detection process, etc. The existing winding and unwinding devices on the market usually include at least one winding roller for winding the wire harness and one unwinding roller for unwinding the wire harness, and the wire harness is routed by synchronously rotating the unwinding roller and the winding roller. Usually, in order to ensure the smooth progress of related processes, workers need to manually operate to tighten the wire harness. Since the positions of the winding roller and the unwinding roller are usually fixed after installation, workers need to rotate the unwinding roller or the winding roller. This operation is not only inconvenient but also time-consuming and laborious. Summary of the Utility Model

[0003] In order to facilitate tightening of the wire harness, the present application provides a wire harness winding and unwinding device.

[0004] The wire harness winding and unwinding device provided by the present application adopts the following technical solution:

[0005] A wire harness winding and unwinding device includes a workbench. A unwinding mechanism and a winding mechanism are adjacently arranged on the workbench. The unwinding mechanism is configured to be able to unwind the wire harness, and the winding mechanism is configured to be able to wind the wire harness; an installation frame is further provided on the workbench, an operating mechanism is provided on the installation frame, a tensioning roller is rotatably arranged on the operating mechanism, and the operating mechanism is configured to be able to drive the tensioning roller to move against the wire harness to complete the tightening of the wire harness.

[0006] By adopting the above technical solution, first, the unwinding mechanism unwinds the wire harness and the winding mechanism winds the wire harness. At this time, by using the operating mechanism to drive the tensioning roller to move against the routed wire harness, the wire harness can be tightened.

[0007] In a specific feasible implementation, the operating mechanism includes a rotating shaft rotatably arranged on the installation frame. One end of the rotating shaft is connected with a connecting rod, and the tensioning roller is rotatably arranged on the connecting rod; a driving component connected with the rotating shaft is further provided on the installation frame, and the driving component is configured to be able to drive the rotating shaft to rotate so as to drive the tensioning roller to press against the wire harness through the connecting rod; a locking component is further provided on the installation frame, and the locking component is configured to be able to limit the rotation of the rotating shaft.

[0008] By adopting the above technical solution, the driving component can drive the rotating shaft to rotate, thereby driving the tensioning roller to rotate through the connecting rod so that the tensioning roller abuts against the wire harness on the wire path. Then, by using the locking component to limit the rotation of the rotating shaft, the reliability of the wire harness being tightened is ensured.

[0009] In a specific feasible embodiment, the driving component includes an installation box arranged on the mounting rack. A first transmission member is arranged inside the installation box, and the first transmission member is installed on the rotating shaft. A second transmission member is also rotatably arranged inside the installation box. The first transmission member and the second transmission member are in transmission connection, and the end of the second transmission member extends outside the installation box and is connected with a handwheel.

[0010] By adopting the above technical solution, manually rotating the handwheel can facilitate applying force to the rotating shaft by the first transmission member and the second transmission member.

[0011] In a specific feasible embodiment, a rubber pad is arranged on the outer wall of the tensioning roller.

[0012] By adopting the above technical solution, the rubber pad can protect the structure of the wire harness.

[0013] In a specific feasible embodiment, the first transmission member is a worm gear, and the second transmission member is a worm. The worm gear and worm can self-lock.

[0014] In a specific feasible embodiment, the locking component includes a connection disk arranged on the mounting rack. A plurality of docking holes are formed in the connection disk along the circumferential direction of the rotating shaft. An installation disk is arranged on the rotating shaft, and a connection hole is formed in the installation disk. The connection hole and one of the docking holes are detachably connected with a pin together.

[0015] By adopting the above technical solution, first, the self-locking characteristic of the worm gear and worm is utilized to ensure that the rotating shaft is difficult to rotate significantly. Then, by connecting the pin to the connection hole and the docking hole together, the installation disk is difficult to rotate, thereby making the rotating shaft difficult to rotate.

[0016] In a specific feasible embodiment, the unwinding mechanism includes a reciprocating driving member arranged on the workbench. A fixing rack is arranged on the reciprocating driving member. A connecting shaft is rotatably arranged on the fixing rack. One end of the connecting shaft is connected with a driving member, and the other end of the connecting shaft is connected with an unwinding roller.

[0017] By adopting the above technical solution, driving the driving member can drive the connecting shaft to rotate, thereby making the unwinding roller rotate for unwinding.

[0018] In a specific feasible embodiment, a retaining disk is arranged on the winding roller, and the retaining disk is used to prevent the wire harness wound on the unwinding roller from detaching from the unwinding roller.

[0019] By adopting the above technical solution, the retaining disc can limit the position of the wire harness.

[0020] In summary, the present application includes at least one of the following beneficial technical effects:

[0021] 1. First, the unwinding mechanism unwinds the wire harness and the winding mechanism winds the wire harness. At this time, by using the operating mechanism to drive the winding roller to move against the wire harness being routed, the wire harness can be tightened.

Then, by connecting pins to the connecting hole and the docking hole together, the mounting disc is difficult to rotate, so that the rotating shaft is difficult to rotate.

Detailed Embodiment

[0029] The following further describes the present application in detail with reference to the drawings.

[0030] An embodiment of the present application discloses a wire harness winding and unwinding device, which is used to tighten the wire harness being routed. Refer to Figure 1, A wire harness winding and unwinding device includes a workbench 1. A unwinding mechanism 2 and a winding mechanism 3 are adjacently arranged on the workbench 1. The unwinding mechanism 2 is configured to be able to unwind the wire harness, and the winding mechanism 3 is configured to be able to wind the wire harness.

[0031] First, wind the wire harness around the unwinding mechanism 2, and then wind one end of the wire harness around the winding mechanism 3. At this time, by synchronously driving the unwinding mechanism 2 and the winding mechanism 3, the wire harness can be routed.

[0032] Refer to Figure 1 and Figure 2 , An installation frame 11 is further provided on the workbench 1. An operating mechanism 4 is provided on the installation frame 11. A tension roller 5 is rotatably arranged on the operating mechanism 4. The operating mechanism 4 is configured to be able to drive the tension roller 5 to move against the wire harness to complete the tensioning of the wire harness.

[0033] In the case of the wire harness routing, moving the tension roller 5 against the wire harness by using the operating mechanism 4 realizes the tensioning of the wire harness.

[0034] Refer to Figure 1 and Figure 3 , The unwinding mechanism 2 and the winding mechanism 3 have the same structure. Taking the structure of the unwinding mechanism 2 as an example: The unwinding mechanism 2 includes a reciprocating driving member 21 arranged on the workbench 1. The reciprocating driving member 21 is preferably a motor. A fixing frame 22 is provided on the reciprocating driving member 21. The reciprocating driving member 21 can drive the fixing frame 22 to move along the front-rear direction. A connecting shaft 23 is rotatably arranged on the fixing frame 22. The connecting shaft 23 is arranged along the front-rear direction. One end of the connecting shaft 23 is connected with a driving member 24. The driving member 24 is preferably a motor. The other end of the connecting shaft 23 is connected with a unwinding roller 25 for winding the wire harness. The unwinding roller 25 is coaxially arranged with the connecting shaft 23. In order to ensure that the wire harness does not break away from the unwinding roller 25, two retaining discs 26 are provided on the unwinding roller. The area between the two retaining discs 26 is the wire harness winding area.

[0035] Refer to Figure 2 and Figure 4 , The operating mechanism 4 includes a rotating shaft 41 rotatably arranged on the installation frame 11. One end of the rotating shaft 41 is connected with a connecting rod 42. The tension roller 5 is rotatably arranged on the connecting rod 42. The tension roller 5 is arranged along the front-rear direction; A driving assembly 43 connected to the rotating shaft 41 is further provided on the installation frame 11. The driving assembly 43 is configured to be able to drive the rotating shaft 41 to rotate so as to drive the tension roller 5 to move against the wire harness through the connecting rod 42; A locking assembly 44 is further provided on the installation frame 11. The locking assembly 44 is configured to be able to limit the rotation of the rotating shaft 41.

[0036] Refer to Figure 2 and Figure 4, the driving assembly 43 includes an installation box 431 provided on the mounting frame 11. A first transmission member 432 is provided inside the installation box 431. The first transmission member 432 is a worm gear, and the first transmission member 432 is installed on the rotating shaft 41. A second transmission member 433 is also rotatably provided inside the installation box 431. The second transmission member 433 is a worm. The worm gear and the worm are engaged, and the worm gear and worm can be self-locked. The end of the second transmission member 433 extends outside the installation box 431 and is connected with a hand wheel 434.

[0037] Manually rotating the hand wheel 434 can make the worm rotate, thereby driving the worm gear to rotate. After that, the rotating shaft 41 can be driven to rotate, and then the tensioning roller 5 can be driven to rotate through the connecting rod 42.

[0038] Refer to Figure 5 , the locking assembly 44 includes a connection disk 441 provided on the mounting frame 11. A plurality of docking holes 442 are formed in the connection disk 441 along the circumferential direction of the rotating shaft 41. An installation disk 443 is provided on the rotating shaft 41. A connection hole 444 is formed in the installation disk 443. The connection hole 444 can be docked with any one of the docking holes 442. A pin 445 is detachably connected to the connection hole 444 and one of the docking holes 442 together.

[0039] The position limiting action of the tensioning roller 5 is as follows: after the tensioning roller 5 is rotated to abut against the wire harness, that is, when it reaches the tensioning position, at this time, based on the self-locking characteristic of the worm gear and worm, it can be ensured that the rotating shaft 41 is difficult to rotate greatly. After that, by connecting the pin 445 to the connection hole 444 and the docking hole 442 together, it can be made difficult for the installation disk 443 to rotate, thereby making it difficult for the rotating shaft 41 to rotate. At this time, the position of the tensioning roller 5 is limited.

[0040] Refer to Figure 4 , in order to protect the wire harness structure, a rubber pad 6 is provided on the outer wall of the tensioning roller 5.

[0041] The implementation principle of a wire harness winding and unwinding device according to an embodiment of the present application is as follows: First, wind the wire harness around the unwinding roller 25 of the unwinding mechanism 2, and then wind one end of the wire harness around the winding mechanism 3. By synchronously driving the unwinding mechanism 2 and the winding mechanism 3, the wire harness can be routed.

[0042] Remove the pin 445, manually rotate the hand wheel 434 to make the worm rotate, thereby driving the worm gear to rotate. After that, the rotating shaft 41 can be driven to rotate, and then the tensioning roller 5 can be driven to rotate through the connecting rod 42 until the tensioning roller 5 abuts against the wire harness. At this time, based on the self-locking characteristic of the worm gear and worm, it can be ensured that the rotating shaft 41 is difficult to rotate greatly. After that, by connecting the pin 445 to the connection hole 444 and one of the docking holes 442 again together, it can be made difficult for the installation disk 443 to rotate, thereby making it difficult for the rotating shaft 41 to rotate. The position of the tensioning roller 5 is limited, and at this time, the tensioning action of the wire harness is completed.

[0043] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
