Description

Technical Field

[0001] The utility model relates to the technical field of wire harness pay-off equipment, in particular to an automobile wire harness pay-off machine. Background Art

[0002] The wire pay-off machine is a device that separates the insulation layer on the wire without damaging the wire. Each time, the wire is placed in the corresponding bayonet to peel off the plastic sheath and metal core of the wire. As the most widely used machine in the wire harness equipment industry, when using the wire pay-off machine, in order to continuously and stably supply the wire harness to the wire pay-off machine, a wire pay-off device that can stably, continuously output, and is safe and reliable is also required.

[0003] At present, most of the pay-off equipment on the market is of the wire roller type, which pays out the cable wound on the wire roller by rotating the wire roller. However, this type of equipment has many unstable factors in the process of continuous pay-off. For example, due to the change in rotational inertia, the speed of the wire roller is uneven, or due to the uneven shape, toughness or hardness of the wire bundle, and inconsistent thickness, the pay-off equipment will work unstably, which will cause the pay-off machine to run idle or pile up. Utility Model Content

[0004] To this end, the utility model provides an automobile wire harness pay-off machine to solve the problem of idling or material piling of downstream equipment in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The automobile wiring harness pay-off machine disclosed in the utility model comprises:

[0007] A wire unwinder, the back side of which is fixed to one end of the connecting beam, and the other end of the connecting beam is fixed to the frame;

[0008] A wire routing device is installed on the connecting beam, the wire harness enters the wire routing device through the wire pay-off device, and the wire routing device drives the wire harness to flow between the wire pay-off device and the wire storage wheel assembly;

[0009] A swing rod, the end of which is connected to the wire storage wheel assembly, the swing rod is hingedly arranged on the frame, and a limit switch is installed at the hinged position, and the limit switch is electrically connected to the wire routing device;

[0010] The swing arm is connected to the frame through a tension spring. When the wire is routed too fast, the winding wire harness causes the wire storage wheel group to lift up, the tension spring is tensioned, the swing arm rises, the limit switch is disconnected, and the routing device is interrupted.

[0011] Furthermore, the wire release device comprises:

[0012] The mounting frame has a back side that is screwed and fixed to one end of the connecting beam, and a guide wheel is arranged on the front side for rotation;

[0013] A wire pressing rod is horizontally inserted on the mounting frame and is parallel to the axis of the wire wheel;

[0014] A wire-paying rod is vertically arranged in the mounting frame, and the wire harness flows into the wire wheel from the end of the wire-paying rod.

[0015] Furthermore, a pay-off wheel is rotatably arranged at the front end of the mounting frame, and a plurality of pay-off holes with different inner diameters are circumferentially arranged on the pay-off wheel, and the pay-off holes are suitable for aligning with the wire wheel and extruding the wire harness through the pay-off holes.

[0016] Furthermore, the pay-off rod comprises:

[0017] A handle, the outer side of which is connected to one end of the rod body, and the other end of the rod body is provided with a wire loop;

[0023] Furthermore, the wire storage wheel group includes a fixed wire wheel and a moving wire wheel, the moving wire wheel is rotatably arranged on the end of the swing rod, and the fixed wire wheel is rotatably arranged on the frame.

[0024] The utility model has the following advantages:

[0025] The automobile wire harness pay-off machine disclosed by the utility model utilizes the wire harness to drive the wire storage wheel group, and drives the rocker arm to deflect through the wire storage wheel group to trigger the limit switch. When the limit switch is disconnected, the wiring device loses power, and the wire harness relies on inertia to route the wire, thereby reducing the wiring speed. The reduced wiring speed will drive the rocker arm through the wire storage wheel group to close the limit switch, thereby allowing the wiring device to operate again. Therefore, the utility model utilizes a mechanical structure to realize an operating mechanism similar to negative feedback regulation, so that the device system reaches or maintains a balance or steady state, and solves the problem of unstable working state of the pay-off machine in the prior art.

DETAILED DESCRIPTION

[0035] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand the other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to Figure 1-Figure 6 The utility model discloses an automobile wire harness pay-off machine, which is used for stably outputting the wire harness to the outside. The device will be described in the following in the form of a specific embodiment.

[0037] In a specific embodiment disclosed in the present utility model, Figure 1 and Figure 5 The main structure of the automobile wire harness pay-off includes a pay-off device 1, a wire routing device 3 and a swing arm 5, wherein the wire harness is wound through the wire storage wheel group 4, and then the wire routing device 3 drives the wire harness to be routed, so that the wire harness first enters the pay-off device 1, passes through the wire routing device 3, and finally is introduced into the wire storage wheel group 4 to pay out. In this embodiment, the back side of the pay-off device 1 is fixed to one end of the connecting beam 2, and the other end of the connecting beam 2 is fixed to the frame 6. The connecting beam 2 is arranged horizontally, and the wire routing device 3 is installed on the connecting beam 2. The wire harness is wound in the wire routing device 3 and drives the wire harness to flow between the pay-off device 1 and the wire storage wheel group 4. On the basis of this structure, in order to ensure the stability of the routing speed, a rocker arm 5 is hingedly provided on the frame 6, and a limit switch is provided at the hinged position with the frame 6. The limit switch is connected to the motor 33 circuit of the routing device 3. When the rocker arm 5 is lifted by the traction force, the limit switch is triggered to disconnect the power supply, and the routing device 3 interrupts operation, and only relies on the inertia of the wire storage wheel group 4 and the driven wheel 35 to drive the routing, so as to reduce the routing speed.

[0038] Specifically, the end of the swing rod 5 is connected to the wire storage wheel group 4. Since the wire storage wheel group 4 is wound with a wire harness, when the wire harness flows too fast, the speed of the wire storage wheel group 4 is difficult to quickly increase with the motor 33, so the wire harness will generate traction and drive the swing rod 5 to rise. The swing rod 5 is connected to the frame 6 through the tension spring 7. The faster the wire is routed, the greater the traction force that drives the swing rod 5 to rise. When the wire storage wheel group 4 with the wire harness wound is lifted, the tension spring 7 is tightened, causing the swing rod 5 to rise, and the limit switch is disconnected, thereby interrupting the operation of the wire routing device 3. In this embodiment, the traction force that causes the swing rod 5 to rise can be offset by adjusting the tightness of the tension spring 7, thereby adjusting the rated routing speed of the equipment.

[0039] In this embodiment, if Figure 4 and Figure 6The wire unwinder 1 includes a mounting frame 11, a conductor wheel 12 and a wire pressing rod 13. The conductor wheel 12 is rotatably arranged on the front of the mounting frame 11, and the back of the mounting frame 11 is screwed and fixed to one end of the connecting beam 2. The wire pressing rod 13 is horizontally inserted on the mounting frame 11, and the wire pressing rod 13 is parallel to the axis of the conductor wheel 12, and the wire pressing rod 13 is suitable for horizontal movement up and down, so that the wire pressing rod 13 can be close to the outer contour surface of the conductor wheel 1, thereby preventing the wire harness on the conductor wheel 12 from falling out.

[0040] In this embodiment, if Figure 2 The front end of the mounting frame 11 is rotatably provided with a pay-off wheel 15, which can squeeze the surface of the wire harness to correct the shape of the wire harness. The pay-off wheel 15 is provided with a plurality of pay-off holes 16 with different inner diameters in the circumferential direction. Since the pay-off holes 16 have different inner diameters, they can handle cables of different thicknesses. Structurally, the pay-off holes 16 are aligned with the wire wheel 12, so that the wire harness can enter in the direction of coinciding with the pay-off holes 16, thereby reducing scratches on the surface of the wire harness.

[0041] In some embodiments, Figure 1 and Figure 4 A wire-paying rod 14 is also vertically arranged in the mounting frame 11, and the wire bundle flows into the guide wheel 12 from the end of the wire-paying rod 14. Specifically, the wire-paying rod 14 includes a handle 141, a rod body 142 and a fastener 143. The rod body 142 is vertically slid downwardly arranged on the mounting frame 11, and one end of the rod body 142 is connected to the handle 141, and the other end of the rod body 142 is provided with a wire-passing ring 144. The uncorrected wire bundle flows into the wire-passing ring 144 along the rod body 142 through the guide wheel 12, and the wire-passing ring 144 limits the fiber core from moving randomly. Furthermore, a fastener 143 is screwed and fixed on the mounting frame 11, and the rod body 142 can be fixed on the mounting frame 11 by tightening the fastener 143, so that the height of the wire-passing ring 144 can be adjusted.

[0042] In some embodiments, Figure 3The wiring device 3 includes a chassis 31, a motor 33 and a cam 34. A driving wheel 32 and a driven wheel 35 are installed in the chassis 31, wherein the driving wheel 32 is connected to the motor 33 and driven by the motor 33 to rotate, while the outer contour surface of the driven wheel 35 is in contact with the driving wheel 32 and can drive the driven wheel 35 to rotate by friction or gear meshing. In this embodiment, the outer shell of the motor 33 is fixedly mounted on the chassis 31, and a slider 36 is vertically slidably arranged above the motor 33, and a driven wheel 35 is rotatably arranged on the slider 36, and the driven wheel 35 is wound with a wire harness. When the driven wheel 35 rotates, it can drive the wire harness to flow. On the other hand, the slider 36 is against the cam 34. A handle is fixedly installed at the end of the cam 34. When the handle is pulled, the cam 34 rotates, pushing the slider 36 to move up and down within the range of the near rest point and the far rest point of the cam 34. When the slider 36 moves upward, the driving wheel 32 and the driven wheel 35 are disengaged, which can block the belt motor 33 from continuing to transmit. Therefore, in an emergency, the transmission can be interrupted in time to prevent the equipment from continuing to operate incorrectly.

[0043] In this embodiment, if Figure 1 and Figure 5 The wire storage wheel group 4 includes a fixed wire wheel 41 and a moving wire wheel 42. The moving wire wheel 42 is rotatably arranged at the end of the swing rod 5, and the fixed wire wheel 41 is rotatably arranged on the frame 6. When the wire running speed is too slow or the driving wheel 32 is out of contact with the driven wheel 35, the wire running speed is rapidly reduced, triggering the limit switch to close and turn on the power supply, so that the motor 33 is restarted to increase the wire running speed. In this way, the running state of the mechanical system can be kept constant.

[0044] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
