Description

Technical Field

[0001] The present invention relates to the technical field of fuse boxes, and in particular to a method for fixing a fuse box and a wiring harness terminal. Background Art

[0002] In the vehicle electrical system, the electrical connection between multiple fuse boxes is a key link to ensure the normal operation of the circuit. At present, wiring harnesses are generally used to achieve electrical connections between fuse boxes, and torque loading devices are used to perform nut fixing operations. During the assembly process, the torque loading device fixes the wiring harness connecting the two fuse boxes with nuts, and at the same time detects the torque value during the nut tightening process in real time. Due to the combination of wiring harnesses and fuse boxes of different specifications, there are differences in the compatible nut models and the torque requirements are also different. Therefore, it is necessary to continuously monitor the torque value during the nut tightening process. Only when the torque value reaches the corresponding target range can the nut fixing operation be considered completed, thereby ensuring the reliability and stability of the electrical connection between the fuse boxes.

[0003] However, existing nut tightening operations often rely on a semi-automatic manual process, which presents significant drawbacks. Operators are prone to errors due to the high workload and difficulty concentrating for extended periods. When tightening a large number of nuts, some may not be tightened to the target torque, potentially causing poor electrical contact between fuse boxes. Nuts may also be tightened repeatedly.

[0046] At present, wiring harnesses are commonly used to achieve electrical connections between fuse boxes, and torque loading devices are used to perform nut fixing operations. During the assembly process, the torque loading device fixes the wiring harness connecting the two fuse boxes through nuts, and at the same time detects the torque value during the screwing of the nuts in real time. However, the existing nut fixing operations mostly adopt a manual semi-automatic method, and this operation mode has obvious disadvantages. During the operation, operators are prone to operational errors due to the high intensity of work and difficulty in concentrating for a long time. When fixing a large number of nuts, some nuts may not be tightened to the target torque value, resulting in the hidden danger of poor contact in the electrical connection between the fuse boxes; at the same time, some nuts may be tightened repeatedly. Therefore, in order to solve the above problems, the present invention provides a method for fixing a fuse box and a wiring harness terminal.

[0047] In this embodiment, if Figure 1 As shown, the method for fixing the fuse box and the wiring harness terminal includes step S10, and step S10 includes steps S11 to S18. Steps S11 to S18 are described in detail below:

[0048] In step S11, upon completion of positioning of the first fuse box 10, the locking information of the first electrical connection position 11 of the first fuse box 10 is obtained. By timely obtaining the locking information, the status of the first electrical connection position 11 can be understood, providing a data basis for subsequent operations, thereby ensuring the accuracy of subsequent operations.

[0049] Step S12: Acquire first position information of the torque device based on the first electrical connection point 11 being in the waiting state. Timely acquisition of position information helps determine the relative position of the torque device and the first electrical connection point 11, thereby accurately controlling the working state of the torque device and ensuring orderly operation.

[0050] In step S13, based on the first position information indicating the first electrical connection point 11, the torque device is activated and one end of the first wiring harness is locked to the first electrical connection point 11 via the first nut until the connection is complete. When the first position information matches the first electrical connection point 11, the torque device is activated and the locking is completed, ensuring the accuracy and security of the first wiring harness connection, preventing loosening, and ensuring connection stability.

[0051] In step S14, the torque device is controlled to switch to a standby state based on the first position information being deviated from the first electrical connection position 11. Setting the torque device to standby state when the position is deviated can avoid erroneous operation.

[0052] In step S15, upon completion of locking the first electrical connection position 11, the locking information of the second electrical connection position 12 of the first fuse box 10 is obtained. Timely acquisition of the locking information of the second electrical connection position 12 can prepare for the locking operation of the second electrical connection position 12 and ensure the continuity of the operation.

[0053] In step S16 , based on the second electrical connection position 12 being in the waiting-to-lock state, second position information of the torque device is obtained, which helps to determine the relationship between the torque device and the second electrical connection position 12 and provides a basis for accurately controlling the torque device.

[0054] In step S17, based on the second position information being the second electrical connection point 12, the torque device is activated and one end of the second wiring harness is locked to the second electrical connection point 12 via the second nut until the locking is complete. When the second position information is consistent with the second electrical connection point 12, the torque device is activated to complete the locking, thereby ensuring the reliability of the second wiring harness connection and stabilizing the circuit connection.

[0055] In step S18, the torque device is controlled to switch to a standby state based on the second position information deviating from the second electrical connection position 12. When the positions do not match, the torque device is put into standby state to prevent misoperation and improve the accuracy of operation.

[0056] Preferably, step S13 includes step S131, and the fixing method of the first embodiment sequentially performs step S11, step S22, step S131, step S14, step S15, step S16, step S17, and step S18. Step S31 is described in detail below:

[0057] Step S131, based on the first position information being the first electrical connection position 11, controls the torque device to switch to the start state and locks one end of the first wiring harness to the first electrical connection position 11 through the first nut, until the torque value and the start-up time of the torque device reach the preset range, and the locking is completed. By starting the torque device to perform the locking operation when the first position information is the first electrical connection position 11, and using the real-time measured torque value and the accumulated start-up time as the judgment criteria for the completion of the locking, it is possible to ensure that the connection between the first wiring harness and the first electrical connection position 11 reaches a stable and reliable state. If the torque value and the start-up time of the torque device are less than the preset range, an alarm is issued to avoid the first nut from loosening due to insufficient torque or too short a locking time, thereby ensuring the accuracy and safety of the connection between the first wiring harness and the first electrical connection position 11 and achieving a stable circuit connection.

[0058] Preferably, step S17 includes step S171, and the fixing method of this embodiment sequentially performs step S11, step S12, step S13, step S14, step S15, step S16, step S171, and step S18. Step S171 may be described in detail below:

[0059] Step S171, based on the second position information being the second electrical connection position 12, controls the torque device to switch to the startup state and locks one end of the second wiring harness to the second electrical connection position 12 through the second nut, until the torque value and startup time of the torque device reach the preset range, and the locking is completed. By starting the torque device to perform the locking operation when the second position information is consistent with the second electrical connection position 12, and using the real-time measured torque value and the accumulated startup time as the basis for judging whether the locking is complete, the stability of the connection between the second wiring harness and the second electrical connection position 12 can be guaranteed. If the torque value and startup time of the torque device are less than the preset range, an alarm is issued to avoid unreliable connection due to improper torque and time parameters, and to prevent the connection from loosening, thereby achieving an accurate and stable connection between the second wiring harness and the second electrical connection position 12.

[0060] In other embodiments, the method for fixing the fuse box and the wiring harness terminal further includes step S20, which includes steps S21 to S24. The method for fixing the fuse box and the wiring harness terminal sequentially performs steps S10 and S20. Steps S21 to S24 are described in detail below:

[0061] In step S21, based on the completion of locking the first and second electrical connection positions 11 and 12 and the completion of positioning the second fuse box 20, the locking information of the third electrical connection position 21 of the second fuse box 20 is obtained. This ensures the validity and accuracy of the obtained information, providing reliable data support for subsequent operations, thereby ensuring the orderly execution of the entire operation process.

[0062] Step S22: Acquire third position information of the torque device based on the third electrical connection point 21 being in the ready-to-lock state. Timely acquisition of the third position information of the torque device helps accurately determine the relative positional relationship between the torque device and the third electrical connection point 21, providing a precise basis for controlling the torque device and thereby ensuring a smooth locking operation.

[0063] In step S23, based on the third position information indicating the third electrical connection point 21, the torque device is activated and one end of the first wiring harness is locked to the third electrical connection point 21 via the third nut until the locking is complete. When the third position information matches the third electrical connection point 21, the torque device is activated to complete the locking. This ensures a secure connection between the first wiring harness and the third electrical connection point 21, preventing loosening and achieving a stable circuit connection, thus ensuring the normal operation of the electrical system.

[0064] In step S24, the torque device is controlled to switch to a standby state based on the third position information deviating from the third electrical connection position 21. Setting the torque device to standby when the position deviates can effectively prevent erroneous operation and improve the safety and reliability of the operation process.

[0065] Preferably, step S23 includes step S231, and the method for fixing the fuse box and the wiring harness terminal sequentially performs step S10, step S21, step S22, step S231, and step S24. Step S231 is described in detail below:

[0066] In step S231, based on the third position information being the third electrical connection position 21, the torque device is controlled to switch to the startup state and one end of the first wiring harness is locked to the third electrical connection position 21 through the third nut until the torque value and startup time of the torque device reach the preset range and the locking is completed. By starting the torque device to perform the locking operation when the third position information is consistent with the third electrical connection position 21, and using the real-time measured torque value of the torque device and the accumulated startup time as the judgment criteria for the completion of the locking, the connection strength and time between the first wiring harness and the third electrical connection position 21 can be accurately controlled. If the torque value and startup time of the torque device are less than the preset range, an alarm is issued to avoid a loose connection due to insufficient torque or too short a time, thereby ensuring a stable and reliable connection between the first wiring harness and the third electrical connection position 21 and ensuring the stability and safety of the electrical connection.

[0067] In other embodiments, step S20 further includes steps S25 to S28, and the method for fixing the fuse box and the wiring harness terminal sequentially performs steps S10, S21, S22, S23, S24, S25, S26, S27, and S28. Steps S25 to S28 are described in detail below:

[0068] In step S25, upon completion of locking the third electrical connection position 21, the lock information for the fourth electrical connection position 22 of the second fuse box 20 is obtained. Acquiring the lock information for the fourth electrical connection position 22 after the third electrical connection position 21 is locked ensures the continuity and orderliness of the operational process, ensuring that the information obtained is at the appropriate operational stage, providing accurate data for subsequent operations, and thus ensuring the smooth progress of the entire fixing process.

[0069] Step S26, based on the fourth electrical connection position 22 being in the waiting-to-lock state, obtain the fourth position information of the torque device. Timely acquisition of the position information of the torque device when the fourth electrical connection position 22 is in the waiting-to-lock state helps determine the relative positional relationship between the torque device and the fourth electrical connection position 22, providing a basis for subsequent precise control of the torque device, thereby ensuring the accuracy of the locking operation.

[0070] In step S27, based on the fourth position information indicating the fourth electrical connection location 22, the torque device is activated and one end of the second wiring harness is locked to the fourth electrical connection location 22 via a fourth nut until the locking is complete. When the fourth position information is consistent with the fourth electrical connection location 22, the torque device is activated to lock the connection. This ensures a secure connection between the second wiring harness and the fourth electrical connection location 22, preventing loose connections and achieving a reliable electrical connection, thereby ensuring the normal operation of the electrical system.

[0071] Step S28: Control the torque device to switch to a standby state based on the fourth position information deviating from the fourth electrical connection position 22. Setting the torque device to standby when the fourth position information deviates from the fourth electrical connection position 22 can effectively prevent erroneous operation and improve reliability of the operation process.

[0072] Preferably, step S27 includes step S271, and the method for fixing the fuse box and the wiring harness terminal sequentially performs step S10, step S21, step S22, step S23, step S24, step S25, step S26, step S271, and step S28. Step S271 can be described in detail below:

[0073] Step S271, based on the fourth position information being located at the fourth electrical connection position 22, controls the torque device to switch to the startup state and locks one end of the second wiring harness to the fourth electrical connection position 22 through the fourth nut, until the torque value and startup time of the torque device reach the preset range, and the locking is completed. By starting the torque device to perform the locking operation when the fourth position information is consistent with the fourth electrical connection position 22, and using the real-time measured torque value of the torque device and the accumulated startup time as the basis for determining whether the locking is complete, the degree of connection between the second wiring harness and the fourth electrical connection position 22 can be accurately controlled. If the torque value and startup time of the torque device are less than the preset range, an alarm is issued to avoid loose connection due to improper torque or insufficient time, thereby ensuring a stable and reliable connection between the second wiring harness and the fourth electrical connection position 22, and ensuring the safety and stability of the electrical connection.

[0074] Furthermore, step S21 includes step S211 and step S212. Step S211 and step S212 are described in detail below:

[0075] Step S211: Based on the locking of the first electrical connection position 11 and the second electrical connection position 12, the first wiring harness and the second wiring harness are bundled and secured. Bundling and securing the wiring harness after the locking of the first electrical connection position 11 and the second electrical connection position 12 is complete can regularize the wiring harness layout, avoid cluttered wiring harnesses that may cause inconvenience or interference in subsequent operations, and provide an orderly wiring harness state for subsequent acquisition of the locking information of the third electrical connection position 21 and other operations.

[0076] In step S212, based on the first and second wiring harnesses being bundled and secured, and the second fuse box 20 being positioned, locking information for the third electrical connection point 21 of the second fuse box 20 is obtained. Obtaining the locking information after the wiring harnesses are bundled and the second fuse box 20 is positioned ensures the accuracy and effectiveness of the obtained information, thereby ensuring the smooth and high-quality operation of the entire fuse box and wiring harness terminal securing process.

[0077] Furthermore, step S212 includes steps S2121 to S2123. Steps S2121 to S2123 are described in detail below:

[0078] Step S2121: After the first and second wiring harnesses are bundled and secured, and the second fuse box 20 is positioned, obtain the model information of the second fuse box 20. Obtaining the model information after the wiring harnesses are bundled and the fuse box is positioned provides an accurate basis for the relevant parameters of subsequent operation steps, ensuring targeted and accurate operations.

[0079] In step S2122, based on the model information, the embedding depths of the third electrical connection point 21 and the fourth electrical connection point 22 of the second fuse box 20 are determined. By accurately determining the embedding depths of the third electrical connection point 21 and the fourth electrical connection point 22 based on the model information, reliable data is provided for subsequent operations based on the embedding depths, avoiding connection problems caused by unclear depths.

[0080] Step S2123: Based on the fact that the embedding depth of the third electrical connection point 21 is greater than the embedding depth of the fourth electrical connection point 22, the locking information of the third electrical connection point 21 is obtained. Figure 2 As shown, the embedding depth of the third electrical connection point 21 is L2, and the embedding depth of the fourth electrical connection point 22 is L1, where L2>L1. Because the first and second wiring harnesses are secured by bundling, connecting the fourth electrical connection point 22 first would constrain the first and second wiring harnesses, making it difficult to connect the first wiring harness to the third electrical connection point 21, resulting in lower efficiency. Therefore, comparing the embedding depths of the third and fourth electrical connection points 21, 22, the third electrical connection point 21 has a greater embedding depth. Connecting the third electrical connection point 21 to the first wiring harness first improves operational efficiency.

[0081] In other embodiments, when one end of the first wiring harness is connected to the first electrical connection point 11 via a first nut and the other end is connected to the third electrical connection point 21 via a third nut; and when one end of the second wiring harness is connected to the second electrical connection point 12 and the other end is connected to the fourth electrical connection point 22 via a fourth nut, the heights of the first, second, third, and fourth nuts are measured simultaneously. The measured heights should be within the set height range; otherwise, the nuts are determined to be loose, and the device will then sound an alarm, reminding personnel to inspect the device and product.

[0082] Preferably, the incoming frequency of the first fuse box 10 is greater than the incoming frequency of the second fuse box 20. Based on this frequency difference, production line resources can be rationally arranged, giving priority to processing production tasks related to the first fuse box 10 with a higher incoming frequency, avoiding production disruptions caused by the frequency difference and improving overall production efficiency.
