Description

Technical Field

[0001] The utility model relates to the technical field of automobile production, in particular to an electric wire conveying device for automobile wire harness production. Background Technique

[0002] An automobile wire harness is the network main body of an automobile circuit and is composed of several electric wires. During the production process of an automobile wire harness, it needs to go through multiple processes of processing before it can be installed on an automobile to prevent the wire harness from malfunctioning during use. However, during the production process, the electric wires need to be conveyed to multiple workshops for processing, which requires a conveying device to let the electric wires be lowered to the required workshops for processing under the drive of the conveying device.

[0003] During the use of the existing electric wire conveying device for automobile wire harness production, during conveying, the wire tension may be too small due to the mismatch of the conveying device speed setting, resulting in problems such as wire entanglement. Workers need to stop the machine in time to adjust the tension, which not only increases the labor intensity of the workers, but also reduces the production efficiency during the stop adjustment. Moreover, when producing wire harnesses of different batches, the required wire specifications and quantities are also different, and the wire guiding mechanism in the conveying device needs to be adjusted to match the conveyed wire path. Usually, the wire guiding mechanism is fixedly arranged, and the corresponding wire guiding mechanism needs to be replaced for use, which increases the procurement cost of the device and reduces the flexibility of the device use.

[0022] Please refer to Figures 1-4As shown in the figure, a wire conveying device for automobile wire harness production includes a frame 1. Above the frame 1, there is a fixed plate 2. At the top of the frame 1, there is a fixed connection with an adjusting frame 3. Inside the frame 1, there is a conveyor belt 18. Outside the conveyor belt 18, there is a clamp 4. By setting the clamp 4, which is fixed on the surface of the conveyor belt 18, it is convenient to clamp and fix the wire during transportation, thereby improving its stability during transportation. On one side of the frame 1, there is a tension sensor 5 and a PLC controller 6 for monitoring the surface tension of the wire. By setting the tension sensor 5, the surface tension of the wire can be monitored. When the tension is too low, in order to prevent the wire from winding, the tension sensor 5 transmits the command for tension adjustment to the PLC controller 6. By setting the PLC controller 6, after receiving the command transmitted by the tension sensor 5, it indirectly drives the adjusting roller 14 to move by turning on the motor 71 to adjust the wire tension. It also includes: a driving component 7 arranged outside the fixed plate 2. Outside the driving component 7, there is a transmission rod 8. By setting the transmission rod 8, when it rotates, one end of the first rotating rod 91 arranged at both ends rotates around it as the center. At both ends of the transmission rod 8, there are respectively rotating components 9. At one end of the rotating component 9, there is a moving plate 10. Inside the moving plate 10, there is a guiding component 11 for improving its moving stability. At the bottom of the moving plate 10, there is a buffer component 12. At one end of the buffer component 12, there is a rotating seat 13. Inside the rotating seat 13, there is an adjusting roller 14 for adjusting the wire tension. By setting the adjusting roller 14, it is convenient to adjust the surface tension of the wire. An adjusting component 15 is arranged inside the adjusting frame 3. Outside the adjusting component 15, there is a fixing component 16 and a wire guiding wheel 17 for preventing the wire from deviating during transportation. By setting the wire guiding wheel 17, it is convenient to limit the moving range of the wire during the wire transportation process to prevent the wire from deviating and winding.

[0023] The driving assembly 7 includes a motor 71 disposed on the top of the fixed plate 2. By providing the motor 71, when it starts, it drives the first bevel gear 72 to rotate; the output end of the motor 71 is provided with the first bevel gear 72. By providing the first bevel gear 72, it is convenient to drive the second bevel gear 73 to rotate; the outer side of the first bevel gear 72 is meshed with the second bevel gear 73. By providing the second bevel gear 73, a transmission rod 8 is fixed to its inner side, which can drive the transmission rod 8 to rotate; the rotating assembly 9 includes a first rotating rod 91 fixed to one end of the transmission rod 8. By providing the first rotating rod 91, while one end of it rotates following the transmission rod 8, the other end drives the second rotating rod 92 to move in the vertical direction as the rotation angle changes; the other end of the first rotating rod 91 is rotatably connected to the second rotating rod 92. By providing the second rotating rod 92, while the first rotating rod 91 drives one end of it to move, the other end drives the moving plate 10 to slide along the outer side of the guide rod 112 for lifting adjustment; the guiding assembly 11 includes a guiding groove 111 opened on the inner side of the moving plate 10, and a guide rod 112 is slidably connected to the inner side of the guiding groove 111. By providing the guiding assembly 11, when the moving plate 10 moves, it slides along the outer side of the guide rod 112, and the guide rod 112 guides the moving path of the moving plate 10; the buffering assembly 12 includes a sliding rod 121 slidably disposed on the inner side of the moving plate 10, and a spring 122 is sleeved on the outer side of the sliding rod 121. By providing the buffering assembly 12, one end of the sliding rod 121 is fixedly connected to the rotating seat 13. Due to the elastic force of the spring 122, it can ensure that when adjusting the wire tension, the wire will not be damaged due to accidental situations such as operation errors and be overstretched.

[0024] The adjusting assembly 15 includes an adjusting groove 152 opened on the inner side of the adjusting frame 3. By providing the adjusting groove 152, it is convenient for the slider 151 to slide along its inner side, and one end of it is provided with an opening through which the wire guide wheel 17 can be taken out, thereby adjusting the number of wire guide wheels 17; the slider 151 is slidably connected to the inner side of the adjusting groove 152. By providing the slider 151, when it slides along the adjusting groove 152, it can drive the wire guide wheel 17 to adjust its position, improving the flexibility of use; a plug rod 161 is rotatably connected to the top of the slider 151, and a plurality of plug slots 162 are horizontally arranged on the top of the adjusting frame 3. By providing the fixing assembly 16, after the wire guide wheel 17 is adjusted to a suitable position, then the plug rod 161 is inserted into the plug slot 162, and the wire guide wheel 17 can be fixedly connected to the adjusting frame 3, improving the stability of the use of the wire guide wheel 17.

[0025] Working principle: During use, first, the fixture 4 fixes the wire. Then, the conveyor belt 18 is started, and the wire moves forward with the conveyor belt 18. When the tension sensor 5 detects that the wire tension is too low, the motor 71 is started through the PLC controller 6, causing the first bevel gear 72 to drive the second bevel gear 73 to rotate. At the same time, the transmission rod 8 drives one end of the first rotating rod 91 to rotate around it as the center. The other end of the first rotating rod 91 drives the second rotating rod 92 to move in the vertical direction as the rotation angle changes, causing the moving plate 10 to slide downward along the outer side of the guide rod 112. The whole wire is stretched to a certain extent through the adjusting roller 14. When it reaches the appropriate tension range, the adjusting roller 14 stops moving, avoiding the situation of winding due to too low wire tension during transportation. When producing wire harnesses of different batches, the redundant wire guide wheel 17 is taken out through the opening at one end of the adjusting slot 152. Then, the slider 151 is pushed to slide along the adjusting slot 152, driving the wire guide wheel 17 to adjust its position. After the wire guide wheel 17 is adjusted to the appropriate position, then the insertion rod 161 is inserted into the insertion slot 162, enabling the wire guide wheel 17 to form a fixed connection with the adjusting frame 3, completing the adjustment and improving the flexibility of the device.
