Description

Technical Field

[0001] The present invention relates to the technical field of automobile wiring harnesses, and in particular to a method for controlling the production of open wiring of automobile wiring harnesses. Background Art

[0002] An automotive wiring harness is a component consisting of copper-stamped contact terminals (connectors) crimped onto wires and cables, then covered with plastic-molded insulation or a metal casing, to form a bundled circuit. Specifically, an automotive wiring harness can include wires, terminals, and waterproof casings. The production process involves wire splitting, crimping, and twisting. Splitting involves stripping the ends of the wires and crimping the terminals. Crimping involves crimping the waterproof casing onto the wires after crimping the terminals.

[0003] However, during the production scheduling process for automotive wiring harnesses, the wiring harness production system must press-fit the corresponding terminal model onto the corresponding wire model according to the production list to form the wiring harness, and then press-fit the corresponding waterproof cover model onto the corresponding wiring harness model. Existing technology often completes the processing of one matching wiring harness model and waterproof cover mold before starting production on the next, resulting in low production efficiency. Furthermore, after changing the required production model, the corresponding waterproof cover mold or wiring harness must be found and replaced, which is time-consuming. Summary of the Invention

This ensures that all wire-splitting machines are operating at full capacity, reducing the number of times they need to change waterproof cover molds, thereby reducing production time and improving production efficiency.

Unless otherwise specified, "plurality" means two or more.

[0018] During the production process of automotive wiring harnesses, different types of waterproof covers need to be pressed onto the corresponding terminal models through a wire-opening machine according to the production list. Since there are many types of waterproof cover models and terminal models, the existing technology often starts producing the next type only after processing a matching model of waterproof cover and terminal, which results in low production efficiency. In addition, after the wire-opening machine changes the required production model, it is necessary to find the corresponding waterproof cover mold or terminal mold for replacement, and the replacement is time-consuming, especially for the waterproof cover mold. In order to reduce the number of mold changes when the wire-opening machine is in full-load production, this embodiment discloses a method for controlling the production of automotive wiring harness wire-opening.

[0019] In this embodiment, if Figure 1 As shown, the automobile wiring harness production scheduling control method may include steps S10 to S50. The above steps are described in detail below: Step S10: Obtain target production data for an automotive wiring harness. The target production data includes the waterproof cover type and the number of wiring harnesses. The automotive wiring harness includes wires, terminals, and waterproof covers. Each end of the wire is sequentially crimped with a terminal and waterproof cover.

[0020] Step S20: Based on the target production data indicating multiple types of waterproof cover, the wire harness production percentage corresponding to each waterproof cover type is obtained. The wire harness production percentage is the ratio of the number of wire harnesses corresponding to the waterproof cover type to the total number of wire harnesses in the target production data. The production scheduling priority of each waterproof cover type is determined based on the wire harness production percentage.

[0021] Step S30, based on the descending order of the proportion of wire harness output, controls the automotive wire harnesses corresponding to the multiple waterproof cover types that are ranked high to be scheduled for production on the wire-splitting machine. There are multiple wire-splitting machines. The number of wire-splitting machines allocated to each waterproof cover type scheduled for production is positively correlated with the proportion of wire harness output. The wire-splitting machine may include a wire-splitting machine body and a waterproof cover mold, and each waterproof cover type corresponds to a waterproof cover mold. Prioritize the automotive wire harnesses corresponding to the waterproof cover types with a larger proportion of wire harness output to ensure that the automotive wire harnesses can be produced on time and in quantity. For example, the wire harness output of waterproof cover type A accounts for 70%, and the proportion of wire-splitting machines allocated to the production of waterproof cover type A is also 70%.

[0022] In step S40, based on all wire-cutting machines being in production, the production completion rate of each waterproof cover type scheduled for production is obtained in real time at a preset frequency. The production completion rate, or the progress of production of the automotive wire harness, is monitored. By monitoring the progress of each waterproof cover type scheduled for production, the wire-cutting machines can be dynamically adjusted to change production types, thereby improving production efficiency. The preset frequency can be set based on production needs.

[0023] Step S50: Based on the maximum difference in the production completion ratios of the various waterproof cover types put into production scheduling exceeding a preset ratio, control some of the wire-cutting machines corresponding to the waterproof cover type with the largest production completion ratio to change the production type to the waterproof cover type that has not been put into production scheduling. Since it takes a long time for the wire-cutting machine to replace the waterproof cover mold, in order to improve production efficiency, during the wire-cutting machine production scheduling process, it is determined by a preset ratio whether the various waterproof cover types put into production scheduling need to be reallocated. When the maximum difference in the production completion ratios of the various waterproof cover types put into production scheduling exceeds the preset ratio, that is, when the production progress of the automotive wire harness corresponding to at least one waterproof cover type is faster, in order to ensure that the automotive wire harnesses corresponding to the various waterproof cover types can simultaneously meet the production targets, the wire-cutting machines corresponding to the waterproof cover type with the largest production completion ratio can be reduced to slow down its production, and the reduced wire-cutting machines can be changed to the waterproof cover type that has not been put into production scheduling. Since the output of waterproof cover type wiring harnesses that have not been put into production scheduling accounts for a low proportion and the production scheduling time is short, this operation can avoid overcapacity caused by unreasonable allocation of wire-cutting machines. At the same time, it can reduce the number of times all wire-cutting machines replace waterproof cover molds, ensuring that this batch of automotive wire harnesses can complete the production goals at the same time and improve production efficiency.

[0024] In this embodiment, the target production data in step S10 may also include the terminal type. The wire-sliding machine also includes a terminal mold. There are multiple terminal types, each corresponding to a terminal mold. When the wire-sliding machine changes the production schedule, the time consumed by replacing the waterproof cover mold is longer than the time consumed by replacing the terminal mold.

[0025] Step S30 may include: Step S31: Based on the descending order of wiring harness production percentage, obtain the reference production times for the top-ranked waterproof cover types. The reference production times are positively correlated with the number of terminal types. The reference production times include the operating time of the wire cutter, the first downtime for replacing the waterproof cover mold, and the second downtime for replacing the terminal mold.

[0026] Step S32, based on the reference production time, the automotive wiring harnesses corresponding to the waterproof cover types with the highest ranking are arranged in descending order, and the automotive wiring harnesses corresponding to the waterproof cover types with the highest ranking are controlled to be scheduled on the wire-opening machine. There are multiple wire-opening machines. The number of wire-opening machines allocated for each waterproof cover type scheduled for production is positively correlated with the proportion of the wiring harness output. The number of wire-opening machines allocated for each waterproof cover type scheduled for production is positively correlated with the reference production time. By considering the proportion of the wiring harness output and the reference production time, the production weight of the automotive wiring harness corresponding to each waterproof cover type can be obtained, thereby improving the rationality of the wire-opening machine in allocating the production type, and giving priority to the automotive wiring harness with the largest proportion of the wiring harness output and the longest reference production time. In the process of wire-opening machine scheduling, all automotive wiring harness production tasks included in a waterproof cover type may correspond to multiple types of terminals. Through the above method, after each wire-opening machine determines the waterproof cover type corresponding to the production schedule, it only needs to replace the terminal mold to produce automotive wiring harnesses of different models, thereby reducing the number of replacements of the waterproof cover mold and improving production efficiency. In addition, since the calculation of the wiring harness output ratio is simpler and faster than that of the reference production time, the present invention can first quickly screen out the automotive wiring harnesses corresponding to the waterproof cover types with large production tasks based on the wiring harness output ratio, and then accurately sort the specific reference production time lengths from the waterproof cover types preliminarily screened. Therefore, the two screenings can save computational complexity and improve response speed, and ensure that the automotive wiring harnesses corresponding to the waterproof cover types put into production scheduling are the automotive wiring harness types with relatively heavy production tasks, thereby ensuring that some wire-opening machines do not need to change the waterproof cover type from the start to the end of the production task, thereby reducing the number of waterproof cover replacements as a whole, thereby improving overall production efficiency.

[0027] In this embodiment, step S40 includes: In step S41, based on all wire-splitting machines being in production, the production completion rate of each waterproof cover type scheduled for production and the production rate of each waterproof cover type not scheduled for production are obtained in real time at a preset frequency. The production completion rate is the ratio of the scheduled completed quantity of automotive wire harnesses for each waterproof cover type to the production target quantity.

[0028] Step S42: Adjusting the preset ratio based on the sum of the wire harness production percentages corresponding to the various waterproof cover types not yet put into production. The preset ratio is negatively correlated with the sum of the wire harness production percentages corresponding to the various waterproof cover types not yet put into production. The smaller the proportion of wire harness production corresponding to the waterproof cover types not yet put into production, the lower the production weight. However, a too small preset ratio may cause the wire drawing machine to frequently change production types. To avoid extending the production time of automotive wire harnesses, adjusting the preset ratio using the above method can delay the wire drawing machine from changing production types to waterproof cover types not yet put into production, thereby improving production efficiency.

[0029] In this embodiment, step S40 may further include: Step S43 adjusts the preset frequency based on the maximum production completion ratio. The preset frequency is positively correlated with the maximum production completion ratio. The preset frequency is adjusted based on the maximum production completion ratio. Specifically, the faster the production schedule for the automotive wiring harness corresponding to the waterproof cover type with the fastest production progress, the higher the preset frequency. This reduces the data lag associated with obtaining the production completion ratio for each waterproof cover type in real time, ensuring the accuracy of the wire cutter's production scheduling changes, reducing the number of waterproof cover mold changes, and improving production efficiency.

[0030] In this embodiment, the target production data in step S10 may also include the terminal type. There are many types of terminals. When the wire cutter changes the production type, the time consumed by replacing the waterproof cover mold is longer than the time consumed by replacing the terminal mold.

[0031] Step S50 includes: Step S51: Based on the maximum difference between the production completion rates of multiple waterproof cover types scheduled for production exceeding a preset ratio, first terminal data and second terminal data are acquired. The first terminal data includes the terminal types of the automotive wiring harness to be scheduled for production, corresponding to the waterproof cover type with the highest production completion rate. The second terminal data includes the terminal types of the automotive wiring harness corresponding to the waterproof cover types not yet scheduled for production.

[0032] In step S52, if the remaining unscheduled wiring harness production ratio is greater than 0 (i.e., there are waterproof cover types that have not been scheduled for production), it is determined whether the waterproof cover types that have not been scheduled for production meet the production scheduling conditions. The production scheduling conditions are that any terminal type in the second terminal data is the same as any terminal type in the first terminal data.

[0033] Step S53: Based on the waterproof cover type that has not been put into production scheduling meeting the production scheduling conditions, control some of the opening machines corresponding to the waterproof cover type with the largest production completion ratio to change the production scheduling type to the waterproof cover type that has not been put into production scheduling.

[0034] Through the above method, when the wire-cutting machine changes the production type to the automotive wiring harness corresponding to the waterproof cover type that has not been put into production, priority is given to selecting a waterproof cover type with the same terminal type as the automotive wiring harness corresponding to the waterproof cover type that has been put into production with the largest production completion ratio among the multiple waterproof cover types that have not been put into production, thereby reducing the number of times the wire-cutting machine changes the terminal mold and improving production efficiency.

[0035] In this embodiment, step S50 may further include: In step S54, based on the remaining unscheduled wiring harness production accounting for zero (i.e., all waterproof cover types are scheduled on the wire-cutting machines), the wire-cutting machines corresponding to the waterproof cover type with the highest production completion rate are controlled to change their production schedule to the waterproof cover type with the lowest production completion rate. This method slows down the production of automotive wiring harnesses corresponding to the waterproof cover type with the highest production completion rate, dynamically adjusts the waterproof cover types assigned to all wire-cutting machines during the production scheduling process, enables simultaneous production of automotive wiring harnesses corresponding to multiple waterproof cover types, reduces the number of waterproof cover mold changes required by all wire-cutting machines, and improves production efficiency.

[0036] In some other embodiments, step S54 may include: Step S541: Based on the percentage of remaining wiring harness output not yet put into production being 0, third terminal data and fourth terminal data are obtained; the third terminal data includes the terminal type of the automotive wiring harness currently being scheduled, corresponding to the waterproof cover type with the highest production completion ratio; the fourth terminal data includes the terminal type of the automotive wiring harness currently being scheduled, corresponding to the waterproof cover type with the lowest production completion ratio; Step S542: Based on the third terminal data and the fourth terminal data, it is determined whether there is a wire-splitting machine among all the wire-splitting machines corresponding to the waterproof cover type with the highest production completion rate that meets the allocation condition; the allocation condition is that any terminal type in the third terminal data is the same as any terminal type in the fourth terminal data; In step S543, based on the existence of a wire-splitting machine that meets the allocation conditions among all the wire-splitting machines corresponding to the waterproof cover type with the highest production completion ratio, the wire-splitting machines that meet the allocation conditions are controlled to change the production type to the waterproof cover type with the lowest production completion ratio. Through the above method, when there is no waterproof cover type that has not been put into production, the wire-splitting machine corresponding to the waterproof cover type with the highest production completion ratio in production can be changed to the wire-splitting machine with the same terminal type corresponding to the lowest production completion ratio in production. This allows the number of wire-splitting machines allocated to be dynamically adjusted to balance the production progress of automotive wiring harnesses corresponding to multiple waterproof cover types. At the same time, when the wire-splitting machine changes its production type, it only needs to replace the waterproof cover mold, reducing the time spent on mold replacement and improving production efficiency.

[0037] In this embodiment, the correlation between the number of wire-splitting machines assigned in step S32 and the reference production duration is greater than the correlation between the number of wire-splitting machines assigned and the proportion of wire harness output. In other words, the reference production duration has a greater weight on the number of wire-splitting machines assigned. This configuration allows for more accurate allocation of production schedules to wire-splitting machines, avoids overcapacity of wire-splitting machines, and improves production efficiency.

[0038] In this embodiment, the target production data in step S10 also includes the harness diameter, which is the diameter of the wires. The reference production time in step S31 is negatively correlated with the average harness diameter of the automotive harness corresponding to the waterproof cover type. The wires in automotive harnesses come in a variety of diameters. Before the wire-splitting machine begins production, the wires need to be wound onto a harness drum so that they can be output during production. The larger the diameter of the wire, the shorter the length that can be wound onto the harness drum. During the production process of the harness, the average harness diameter can be obtained to determine the reference frequency for replacing the harness drum. This can reduce the actual frequency of harness drum replacement, thereby controlling the reference production time and improving production efficiency.

[0039] In this embodiment, the preset ratio is at least greater than 30%. This avoids frequent changes in production schedules for the wire cutting machine due to a too small preset ratio, reduces the number of mold changes for the wire cutting machine, and thus reduces the downtime of the wire cutting machine for mold changes, thereby improving production efficiency.

[0040] In this embodiment, the wire slitting machine also includes a guide tube; after unwinding, the wire passes through the guide tube and enters the wire slitting machine body for cutting and crimping; the caliber of the guide tube corresponds to the diameter of the wire harness; and the reference production time also includes a third downtime for replacing the guide tube. When different types of wires are output to the wire slitting machine for crimping terminals, they need to be guided by the corresponding type of guide tube. On the wire slitting machine, the replacement time for the waterproof cover mold, the replacement time for the terminal mold, the replacement time for the guide tube, and the replacement time for the wire are in descending order, that is, the first downtime is greater than the second downtime, and the second downtime is greater than the third downtime.

[0041] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present disclosure, and that in actual applications, various changes may be made thereto in form and detail without departing from the scope of the present disclosure.
