Description

Technical Field

[0001] This invention relates to the field of automotive wiring harness technology, and more specifically, to a method and system for scheduling the opening of automotive wiring harnesses. Background Technology

[0002] Automotive wiring harnesses generally consist of several parts, primarily wires of fixed length, terminals at both ends of the wires, and protective sleeves. These wires, terminals, and protective sleeves can be combined in many ways. Wire cutting refers to taking the appropriate length of wire and installing the terminals and protective sleeves at both ends. Therefore, in automotive wiring harness manufacturing companies, to increase production volume, multiple machines are often used simultaneously to assemble wiring harnesses of different specifications. In current technology, to improve production efficiency when there are many types of wiring harnesses to be processed, they are generally classified according to the specifications of the wires, terminals, or protective sleeves, and wire cutting machines are used to cut harnesses of uniform specifications or partially uniform specifications.

[0003] However, in actual working conditions, the crimping machine requires changing the corresponding molds when assembling different terminals and protective sleeves. The replacement time for the protective sleeve mold is longer than that for the terminal mold. Traditional wire cutting methods waste significant downtime on changing these molds, reducing production efficiency. Therefore, there is an urgent need for a method for automotive wire harness cutting that can rationally schedule downtime when dealing with multiple wire harness specifications. Summary of the Invention

[0004] To address the problem of low production efficiency in automotive wiring harness production due to the wide variety of specifications, this invention provides a method for scheduling automotive wiring harness opening, the method comprising:

[0005] Step S10: Obtain and accumulate the target production data of automotive wiring harnesses at a preset cycle. The target production data includes waterproof sleeve type, wiring harness output and terminal type.

[0006] Step S20: Based on the target production scheduling data, perform an accumulation to obtain the wire harness production and terminal type quantity corresponding to each waterproof sleeve type;

[0007] Step S30: Calculate the downtime percentage for each type of waterproof sleeve based on the following formula:

[0008] x=(m*t1) / (m*t1+n*t2); t1>t2;

[0009] Where x is the percentage of downtime; m is the number of terminal types; t1 is the reference downtime for the wire cutting machine to change the terminal mold; n is the wire harness output; t2 is the reference production time for a single automotive wire harness; the reference downtime for the wire cutting machine to change the terminal mold is less than the reference downtime for the wire cutting machine to change the waterproof sleeve mold.

[0010] Step S40: Based on the order of decreasing wire harness production for each type of waterproof sleeve, determine whether each type of waterproof sleeve meets the first production scheduling condition; the first production scheduling condition includes that the downtime percentage corresponding to the waterproof sleeve type is less than a preset percentage.

[0011] Step S50: Based on the fact that the waterproof sleeve type meets the first production scheduling condition, the waterproof sleeve type is scheduled for production on the opening machine.

[0012] In some embodiments, the first production scheduling condition further includes the wire harness production corresponding to the waterproof sleeve type being greater than the first benchmark production.

[0013] In some embodiments, step S20 includes: performing an accumulation based on the target production scheduling data, obtaining the wire harness production and terminal type quantity corresponding to each waterproof sleeve type, and obtaining the number of shutdowns of the wire opening machine;

[0014] Step S50 includes:

[0015] Step S51: Based on the fact that the waterproof sleeve type meets the first production scheduling condition, accumulate the first type quantity of the waterproof sleeve type that meets the first production scheduling condition;

[0016] Step S52: Based on the fact that the quantity of the first type is greater than or equal to the number of shutdown machines of the opening machine, the waterproof sleeve types that meet the first production scheduling conditions are sequentially scheduled for production on the opening machine.

[0017] In some embodiments, step S50 further includes:

[0018] Step S53: Based on the fact that the number of the first type is less than the total number of the wire cutting machines, the automotive wiring harnesses corresponding to the waterproof sleeve types that meet the first production scheduling conditions are sequentially scheduled on the wire cutting machines, and the waterproof sleeve types to be scheduled are obtained.

[0019] Step S54: Calculate the total production time for each type of waterproof sleeve to be scheduled for production according to the following formula:

[0020] T = m * t1 + n * t2;

[0021] Where T is the total production time;

[0022] Step S55: Arrange production of the waterproof sleeve types in descending order of total production time.

[0023] In some embodiments, step S54 includes:

[0024] Step S541: Based on the waterproof sleeve type to be scheduled for production, determine in turn whether the waterproof sleeve type meets the second production scheduling condition; the second production scheduling condition includes that the wire harness production corresponding to the waterproof sleeve type is greater than the second benchmark production.

[0025] Step S542: Based on the fact that the waterproof sleeve type meets the second production scheduling condition, calculate the total production time for each of the waterproof sleeve types to be scheduled according to the following formula:

[0026] T = m * t1 + n * t2;

[0027] Where T is the total production time.

[0028] In some embodiments, the second benchmark output is equal to or less than the first benchmark output.

[0029] In some embodiments, step S542 includes:

[0030] Step S5421: Based on the fact that the waterproof sleeve type meets the second production scheduling condition, accumulate the second type quantity of the waterproof sleeve type that meets the second production scheduling condition;

[0031] Step S5422: Based on the fact that the sum of the quantity of the second type and the quantity of the first type is less than the number of shutdowns of the opening machine, reduce the second benchmark output;

[0032] Step S5423: Repeat steps S5421 to S5423 until the sum of the quantity of the second type and the quantity of the first type is greater than or equal to the number of shutdown machines of the opening machine.

[0033] Step S5424: Based on the fact that the sum of the quantity of the second type and the quantity of the first type is greater than the total number of the opening machines, calculate the total production time corresponding to the waterproof sleeve type that satisfies the second production scheduling condition according to the following formula:

[0034] T = m * t1 + n * t2;

[0035] Where T is the total production time.

[0036] In some embodiments, the first benchmark yield is the average yield of the wiring harness corresponding to each of the waterproof sleeve types.

[0037] In some embodiments, the preset ratio is between 2% and 5%.

[0038] In a second aspect, the present invention provides an automotive wiring harness unloading scheduling system, wherein the automotive wiring harness unloading scheduling system is applied to the automotive wiring harness unloading scheduling method in the first aspect, and the automotive wiring harness unloading scheduling system includes:

[0039] The first acquisition module acquires and accumulates the target production data of automotive wiring harnesses at a preset period. The target production data includes waterproof sleeve type, wiring harness production volume and terminal type.

[0040] The second acquisition module completes an update based on the target production scheduling data, and acquires the wire harness production and terminal type quantity corresponding to each waterproof sleeve type;

[0041] The processing module calculates the percentage of downtime for each type of waterproof sleeve based on the following formula:

[0042] x=(m*t1) / (m*t1+n*t2); t1>t2;

[0043] Where x is the percentage of downtime; m is the number of terminal types; t1 is the reference downtime for the wire cutting machine to change the terminal mold; n is the wire harness output; t2 is the reference production time for a single automotive wire harness; the reference downtime for the wire cutting machine to change the terminal mold is less than the reference downtime for the wire cutting machine to change the waterproof sleeve mold.

[0044] The judgment module determines whether each waterproof sleeve type meets the first production scheduling condition based on the decreasing order of the wire harness production corresponding to each type of waterproof sleeve. The first production scheduling condition includes the downtime percentage corresponding to the waterproof sleeve type being less than a preset percentage.

[0045] The control module sends a production scheduling signal to the opening machine based on the waterproof sleeve type meeting the first production scheduling condition.

[0046] To address the problem of low production efficiency in wire harness manufacturing due to the wide variety of automotive wiring harness specifications, this invention offers the following advantages:

[0047] This invention reduces the frequency of time-consuming waterproof sleeve mold changes by periodically summarizing orders and centralizing the production of wire harnesses of the same waterproof sleeve type. Simultaneously, it schedules the production sequence of wire harnesses of the same waterproof sleeve type based on output volume and downtime percentage, allowing the production of wire harnesses of the same waterproof sleeve type that suffers from low efficiency due to frequent terminal mold changes to be postponed to later cycles. Finally, weekly data updates allow for flexible task adjustments, reducing downtime and dynamically optimizing the production rhythm, making it particularly suitable for handling the production of multi-specification wire harnesses.

[0051] The present disclosure will now be discussed with reference to several exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and thus implement the present disclosure, and are not intended to imply any limitation on the scope of the disclosure.

These terms are primarily for the purpose of better describing this application and its embodiments and are not intended to limit the indicated devices, elements, or components to having a specific orientation or being constructed and operated in a specific orientation. Furthermore, some of the above terms may be used to indicate other meanings besides orientations or positional relationships; for example, the term "upper" may in some cases indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application according to the specific circumstances. In addition, the terms "installed", "set up", "equipped with", "connected", and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, elements, or components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. Furthermore, the terms "first," "second," etc., are mainly used to distinguish different devices, elements, or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0053] During the cutting process of automotive wiring harnesses, if the wiring harness specifications are different, different protective sleeves or terminals need to be installed. This requires stopping the cutting machine to replace the corresponding molds. The replacement time for protective sleeve molds is longer than that for terminal molds. Existing technologies that classify wiring harnesses or terminals / protective sleeves according to their specifications and perform cutting on the same cutting machine specifically for wiring harnesses of the same specification or some with similar specifications are insufficient to significantly reduce downtime. Therefore, this embodiment provides an automotive wiring harness cutting scheduling method, such as... Figure 1 As shown, the automotive wiring harness disconnection and routing method may include steps S10 to S50, and each step is described in detail below:

[0054] Step S10: Obtain and accumulate the target production schedule data for automotive wiring harnesses at a preset cycle. The preset cycle can be one week, and the target production schedule data can include waterproof sleeve type, wiring harness production volume, and terminal type.

[0055] Step S20: Based on the target production scheduling data, perform an accumulation to obtain the wire harness production volume and terminal type quantity corresponding to each waterproof sleeve type. That is, after each preset cycle, the re-accumulated target production scheduling data is statistically analyzed, and the targets are classified according to the waterproof sleeve type while obtaining the wire harness production volume and terminal type quantity corresponding to each type of waterproof sleeve.

[0056] Step S30: Calculate the downtime percentage for each type of waterproof sleeve based on the following formula:

[0057] x=(m*t1) / (m*t1+n*t2); t1>t2;

[0058] Where x is the percentage of downtime; m is the number of terminal types; t1 is the reference downtime for changing the terminal mold of the wire cutting machine; n is the wire harness output; and t2 is the reference production time for a single automotive wire harness.

[0059] The downtime percentage calculated by this formula is the proportion of downtime caused by changing m types of terminal molds to the total production time when producing n wire harnesses without needing to change the waterproof sleeve.

[0060] The reference downtime for changing the terminal mold of the wire cutting machine is less than the reference downtime for changing the waterproof sleeve mold. Therefore, the target production wire harnesses are classified according to the type of waterproof sleeve, and wire harnesses with the same waterproof sleeve are processed at one time. This can minimize the downtime required for changing the waterproof sleeve mold during production and improve the production efficiency of automotive wire harnesses.

[0061] Step S40: Based on the decreasing order of wire harness production for each type of waterproof sleeve, determine whether each waterproof sleeve type meets the first production scheduling condition. The first production scheduling condition includes that the downtime percentage corresponding to the waterproof sleeve type is less than a preset percentage. The downtime for each waterproof sleeve type depends on the relationship between the number of terminal types and the total number of wire harnesses contained in that waterproof sleeve type.

[0062] Step S50: Based on the waterproof sleeve type meeting the first production scheduling condition, the waterproof sleeve type is scheduled for production on the wire cutting machine. If the first production scheduling condition is met, it means that the downtime for changing the terminal mold is relatively small, thus ensuring high production efficiency. If the downtime required for changing the terminal mold is too high, the wire harness of that waterproof sleeve type will not be scheduled for production temporarily, and will be rescheduled after the data is accumulated in the next preset cycle. In addition, the production scheduling order is consistent with the order of decreasing wire harness output, thereby minimizing the number of times the waterproof sleeve mold needs to be changed during production. Therefore, this invention takes into account the number of times the waterproof sleeve mold and terminal mold need to be changed, and can minimize the downtime of the wire cutting machine during a certain production cycle, thereby improving production efficiency.

[0063] The target production scheduling data is compiled according to a preset cycle. All target production harnesses are then categorized by waterproof sleeve type. Harnesses with the same waterproof sleeve type are produced together, minimizing downtime required for changing waterproof sleeve molds. The downtime percentage for each type of harness with the same waterproof sleeve type is calculated and scheduled in descending order of harness production volume, thus eliminating waterproof sleeve types with excessively low production efficiency. Furthermore, scheduling by harness production volume means that harnesses scheduled later in the production sequence require waterproof sleeve mold changes more frequently than those scheduled earlier. If any waterproof sleeve types remain unproduced before the next preset cycle, they can be rescheduled after data accumulation, further reducing the number of waterproof sleeve mold changes.

[0064] In this embodiment, the first production scheduling condition also includes that the output of wire harnesses corresponding to the waterproof sleeve type is greater than the first benchmark output. That is, if the quantity of wire harnesses of the same type of waterproof sleeve is too small, production will not be scheduled temporarily, and there is no need to judge the first production scheduling condition. Instead, the production can be rescheduled after the data is accumulated in the next preset cycle. At the same time, excluding wire harnesses of the same type with low output can reduce the frequency of changing waterproof sleeve molds, thereby improving the overall production efficiency.

[0065] In this embodiment, step S20 may include: completing an accumulation based on the target production scheduling data, obtaining the wire harness production and terminal type quantity corresponding to each waterproof sleeve type, and obtaining the number of shutdown wire opening machines, which is also the number of wire opening machines that can be scheduled but are in a shutdown or standby state.

[0066] Step S50 may include steps S51 to S52, and each step is described in detail below:

[0067] Step S51: Based on the waterproof sleeve type meeting the first production scheduling condition, accumulate the number of first-type waterproof sleeves that meet the first production scheduling condition. For example, if the number of first-type is 5, it means that there are 5 types of waterproof sleeves that meet the first production scheduling condition.

[0068] Step S52: Based on the fact that the number of the first type is greater than or equal to the number of shutdown machines of the opening machine, the waterproof sleeve types that meet the first production scheduling conditions are scheduled to be produced sequentially on the opening machine. This means that the waterproof sleeve types that can be put into production are saturated, which can ensure that all opening machines are in working condition and there are no idle opening machines, thereby enabling the workshop's processing efficiency to reach its theoretical maximum.

[0069] In this embodiment, step S50 may further include steps S53 to S55, each of which is described in detail below:

[0070] Step S53: Based on the fact that the quantity of the first type is less than the total number of wire cutting machines, the automotive wiring harnesses corresponding to the waterproof sleeve types that meet the first production scheduling conditions are sequentially scheduled on the wire cutting machines, and the waterproof sleeve types to be scheduled are obtained. Among them, the waterproof sleeve types to be scheduled do not meet the first production scheduling conditions.

[0071] Step S54: Calculate the total production time for each type of waterproof sleeve to be produced according to the following formula:

[0072] T = m * t1 + n * t2;

[0073] Where T is the total production time; m is the number of terminal types; t1 is the reference downtime for changing the terminal mold of the wire cutting machine; n is the wire harness output; and t2 is the reference production time for a single automotive wire harness.

[0074] Step S55: Schedule production for each type of waterproof sleeve in descending order of total production time. For waterproof sleeve types that do not meet the first scheduling condition and have a long terminal mold changeover time, if an idle wire-opening machine is available, production can be scheduled in descending order of total production time for each waterproof sleeve type, thus avoiding downtime of the wire-opening machine and wasting production equipment. Simultaneously, scheduling production in descending order of total production time reduces the number of times waterproof sleeve molds need to be changed.

[0075] In this embodiment, step S54 may include steps S541 to S542, and each step is described in detail below:

[0076] Step S541: Based on the types of waterproof sleeves to be produced, determine whether each type of waterproof sleeve meets the second production scheduling condition. The second production scheduling condition includes that the wire harness production volume corresponding to the waterproof sleeve type is greater than the second baseline production volume.

[0077] Step S542: Based on the fact that the waterproof sleeve type meets the second production scheduling condition, calculate the total production time corresponding to each type of waterproof sleeve to be scheduled according to the following formula:

[0078] T = m * t1 + n * t2;

[0079] Where T represents the total production time.

[0080] By screening the second production scheduling conditions, we can prioritize the production of waterproof sleeve types with longer total production times, thereby reducing the number of times waterproof sleeve types need to be changed.

[0081] The second production scheduling condition is based on the first production scheduling condition. It is difficult to balance the number of times the waterproof sleeve mold and terminal mold are changed. Therefore, it is necessary to focus on reducing the number of times the waterproof sleeve mold is changed to minimize downtime. Secondly, the wire harness production corresponding to this type of waterproof sleeve is limited to be greater than the second benchmark production. This can prevent the waterproof sleeve type with low wire harness production but many terminal types from being prioritized for production. To a certain extent, the terminal mold is taken into consideration, and the number of times the terminal mold is changed is also minimized, so as to ensure the production efficiency of the wire opening machine.

[0082] In this embodiment, the second benchmark output can be equal to or less than the first benchmark output. When the second benchmark output is equal to the first benchmark output, waterproof sleeve types that do not meet the first scheduling conditions but have a large total number can be screened out for scheduling to ensure production volume. When the second benchmark output is less than the first benchmark output, waterproof sleeve types that have a smaller total number but still meet a certain quantity can be screened out, and further screening can be conducted to select waterproof sleeve types with short total processing time, i.e., fewer terminal replacements, for scheduling.

[0083] In this embodiment, step S542 may include steps S5421 to S5424, and each step is described in detail below:

[0084] Step S5421: Based on the fact that the waterproof sleeve type meets the second production conditions, accumulate the second type quantity of waterproof sleeves that meet the second production conditions.

[0085] Step S5422: Based on the fact that the sum of the quantity of the second type and the quantity of the first type is less than the number of shutdown machines for the opening machine, the second baseline output is reduced. That is, when all waterproof sleeve types that meet the first and second production scheduling conditions are put into production, but there are still idle opening machines, the second production scheduling condition standard is lowered to increase the quantity of the second type of waterproof sleeves that can be scheduled for production.

[0086] Step S5423: Repeat steps S5421 to S5423 until the sum of the quantity of the second type and the quantity of the first type is greater than or equal to the number of machines that have stopped, so that all machines are put into production, thereby increasing the processing efficiency of the workshop.

[0087] Step S5424: Based on the fact that the sum of the quantity of the second type and the quantity of the first type is greater than the total number of opening machines, calculate the total production time corresponding to the waterproof sleeve type that meets the second production scheduling conditions according to the following formula:

[0088] T = m * t1 + n * t2;

[0089] Where T is the total production time; m is the number of terminal types; t1 is the reference downtime for changing the terminal mold of the wire cutting machine; n is the wire harness output; and t2 is the reference production time for a single automotive wire harness.

[0090] In this embodiment, the first benchmark output can be the average output of the wire harness corresponding to each waterproof sleeve type, so that the first benchmark output can be kept at an appropriate size, which can both filter out waterproof sleeve types with high output and remove those with low output.

[0091] In this embodiment, the preset ratio can be between 2% and 5%, so that fewer terminal types are selected from the waterproof sleeve types, thereby speeding up the processing efficiency.

[0092] This embodiment provides an automotive wiring harness unloading scheduling system, which is applied to automotive wiring harness unloading scheduling methods, such as... Figure 2 As shown, the automotive wiring harness opening and scheduling system may include a first acquisition module 10, a second acquisition module 20, a processing module 30, a judgment module 40, and a control module 50.

[0093] The first acquisition module 10 can acquire and accumulate the target production data of automotive wiring harnesses at a preset cycle. The target production data includes waterproof sleeve type, wiring harness output and terminal type.

[0094] The second acquisition module 20 can complete an update based on the target production scheduling data to obtain the wire harness production and terminal type quantity corresponding to each waterproof sleeve type;

[0095] Processing module 30 can calculate the percentage of downtime for each type of waterproof sleeve based on the following formula:

[0096] x=(m*t1) / (m*t1+n*t2); t1>t2;

[0097] Where x is the percentage of downtime; m is the number of terminal types; t1 is the reference downtime for changing the terminal mold of the wire cutting machine; n is the wire harness output; and t2 is the reference production time for a single automotive wire harness. The reference downtime for changing the terminal mold of the wire cutting machine is less than the reference downtime for changing the waterproof sleeve mold of the wire cutting machine.

[0098] The judgment module 40 can determine whether each type of waterproof sleeve meets the first production scheduling condition based on the decreasing order of wire harness production for each type. The first production scheduling condition includes that the downtime percentage corresponding to the waterproof sleeve type is less than a preset percentage.

[0099] The control module 50 can send a production scheduling signal on the production line starter based on whether the waterproof sleeve type meets the first production scheduling condition.

[0100] Through the step-by-step operation of the first acquisition module 10, the second acquisition module 20, the processing module 30, the judgment module 40, and the control module 50, the wire harnesses to be produced in the preset cycle can be screened out, and the production of each type of waterproof sleeve can be scheduled in the order of decreasing output and increasing downtime percentage, thereby maximizing production efficiency.

[0101] It should be understood that the "this embodiment" mentioned in this invention refers to the technical points described below, and multiple "this embodiments" may refer to the same embodiment or different embodiments.

[0102] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.

The judgment module determines whether each waterproof sleeve type meets the first production scheduling condition based on the decreasing order of the wire harness production corresponding to each type of waterproof sleeve. The first production scheduling condition includes the downtime percentage corresponding to the waterproof sleeve type being less than a preset percentage. The control module sends a production scheduling signal to the opening machine based on the waterproof sleeve type meeting the first production scheduling condition.
