Description

Technical Field

[0001] This application relates to the technical field of vehicle quality control, and particularly to a product quality control method, device, equipment, and computer-readable storage medium. Background Art

[0002] In the field of trial production and even in the field of regular production, product quality control relies on quality standards; and quality standards usually include industry standards, enterprise standards, and national standards; among them, the sources and forms of enterprise standards are diverse, and common ones include recurrence prevention databases and process problem control databases. It should be understood that the recurrence prevention database (i.e., the historical database) is an inspection point database formed by quality problems that occurred in history and were prominent or exceeded certain indicators, while the process problem control database is a database formed by quality problems occurring in the current production process.

[0003] In the related art, for different sources or types of standards, they all need to be decomposed and refined into each production process of the product production process. However, since the production process is composed of individual processes, to decompose each indicator described in the standard into each process, not only a large amount of time is required to compile the inspection form, but also the setting of inspection stations and the determination of inspection timing are needed. It can be seen that this compilation process is long and inefficient, resulting in a low control efficiency of product quality. Summary of the Invention

[0058] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0059] In order to make the purpose, technical solution and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0060] In a first aspect, the embodiment of the present application provides a product quality control method.

[0061] In one embodiment, with reference to Figure 1 , Figure 1 is the flowchart of the product quality control method according to the embodiment of the present application. As Figure 1 shown, the product quality control method includes:

[0062] Step S10: Determine the target production process code from a preset code mapping relationship library based on the target part code of the target functional part, where the code mapping relationship library is used to store the mapping relationship between the part code of the functional part, the function code of the functional group block where the functional part is located, and the production process code.

[0063] Exemplarily, it can be understood that vehicle parts generally include standard parts and functional parts, and this embodiment mainly realizes the quality control of functional parts. Among them, regardless of the type of product, the same kind of product usually has a high degree of similarity in function and structure, and this is particularly prominent in automobiles. Therefore, in this embodiment, all functional parts will be first divided according to function to generate different functional blocks, that is, each functional block includes at least one functional part, and a unique identification code (i.e., function code) is set for each functional block; it should be understood that each functional part has a unique identification code (i.e., part code), so for each functional part, a mapping relationship can be constructed between its part code and the function code of the functional block where it is located; at the same time, since the production process corresponding to the part code itself also has a subordinate relationship with the part code, that is, there is a mapping relationship between the production process code and the part code, the function code can establish an indirect subordinate relationship through the part code and the production process code, so a mapping relationship between the part code, the function code, and the production process code can be constructed, thereby realizing the preset of the coding mapping relationship library.

[0064] It should be noted that the target functional parts in this embodiment refer to the functional parts that need to be subject to quality control. Among them, before performing quality control on the target functional parts in this embodiment, it is necessary to find the corresponding target production process code from the mapping relationship stored in the coding mapping relationship library based on the target part code of the target functional part, so as to provide an execution basis for subsequent quality control.

[0065] Further, in one embodiment, before the step of determining the target production process code from the preset coding mapping relationship library based on the target part code of the target functional part, it further includes:

[0066] Divide all functional parts according to whether their functions are the same to form multiple functional blocks, and create a function code corresponding to each functional block;

[0067] For each functional block, create a mapping relationship between the function code of the functional block and the part code of each functional part included in it, so that the function code establishes a mapping relationship with the production process code corresponding to the part code through the part code, so as to form a coding mapping relationship library.

[0068] Exemplarily, in this embodiment, all functional parts will be divided according to whether their functions are the same to obtain multiple functional blocks; for example, as shown in Figure 2 If functional parts 11, 12, and 13 have the same function, then functional parts 11, 12, and 13 are divided into functional block 1, and if functional parts 21 and 22 have the same function, then functional parts 21 and 22 are divided into functional block 2, and so on, to obtain functional block N; at the same time, a function code is set for each functional block.

[0069] See Figure 3 As shown, for each functional block, there is a mapping relationship between the part codes of all functional components in the functional block and their function codes, so that the function codes can establish a mapping relationship with the production process codes through the part codes, and further the coding mapping relationship library stores the subordinate relationships among the part codes, function codes, and production process codes. For example, assume that the function code of functional block 1 is Z1 and it includes functional components 11, 12, and 13, and the part codes of functional components 11 to 13 are X1, X2, and X3 in sequence. Then, the mapping relationships between Z1 and X1, Z1 and X2, and Z1 and X3 can be constructed. At the same time, since the production process codes corresponding to the part codes X1, X2, and X3 are Y1, Y2, and Y3 in sequence, there are automatically mapping relationships between Z1 and Y1, Y2, and Y3 respectively.

[0070] Step S20: Determine the target inspection standard according to the target production process code, and the target inspection process code corresponding to the target inspection standard is the same as the target production process code.

[0071] Exemplarily, in this embodiment, an inspection process code will be set for the existing inspection standards. It should be understood that for the existing inspection standards, it is determined which processes (each process has a corresponding production process code) they need to be executed on. For example, during the process of the production process named "installing the instrument panel assembly" with the production process code GX111, the problem of "the surface difference of the instrument panel gap exceeds the tolerance" occurs. Then, the inspection standard corresponding to this problem, "whether the surface difference of the instrument panel gap exceeds the tolerance", needs to be executed during the process of installing the instrument panel assembly. Therefore, the production process code GX111 can be used as the inspection process code of this inspection standard (i.e., "whether the surface difference of the instrument panel gap exceeds the tolerance"). It can be seen that after determining the target production process code, the target inspection process code corresponding to the target production process code can be found based on the principle that the production process code is the same as the inspection process code, and then the corresponding target inspection standard can be found through the target inspection process code.

[0072] Further, in an embodiment, before the step of determining the target inspection standard according to the target production process code, it further includes:

[0073] Decompose the existing standards and the standards in the recurrence prevention database to determine the inspection standards corresponding to each functional component;

[0074] For each functional component, use the production process code corresponding to the functional component as the inspection process code of its inspection standard to form an inspection library.

[0075] Exemplarily, in this embodiment, the data in the existing standard and recurrence prevention database (i.e., the standard, also the inspection items) will be decomposed to refine to specific application scenarios, and then the inspection standards corresponding to each functional component will be determined; then, the production process code corresponding to the functional component will be found through the part code of the functional component, and this production process code will be used as the inspection process code of the inspection standard of the functional component, so that the inspection process is affiliated under the production process, and then an inspection library is generated; it can be seen that in this embodiment, the association relationship between the production process code and the inspection standard is constructed through the inspection process code.

[0076] Further, in one embodiment, determining the target inspection standard according to the target production process code includes:

[0077] Judging whether there is a target inspection process code in the inspection library that is the same as the target production process code;

[0078] If it exists, the inspection standard corresponding to the target inspection process code will be used as the target inspection standard;

[0079] If it does not exist, at least one other production process code corresponding to the function code of the functional block where the target functional component is located will be determined from the code mapping relationship library, and the target inspection standard will be determined based on all other production process codes.

[0080] Exemplarily, in this embodiment, when determining the target inspection standard of the target functional component, it is necessary to first search the inspection library to judge whether there is a target inspection process code in the inspection library that is the same as the target production process code; if it exists, it means that the inspection standard corresponding to the target functional component already exists, and the inspection standard corresponding to the target inspection process code will be used as the target inspection standard of the target functional component. For example, if the target functional component is a battery and its corresponding target production process code is GX1025, at this time, if it is found according to the mapping relationship stored in the inspection library that there is an inspection process code with the code GX1025, then GX1025 will be used as the target inspection process code, and then the inspection standard corresponding to the target inspection process code (such as whether the appearance of the battery is intact) will be used as the target inspection standard of the battery.

[0081] If there is no target inspection process code in the inspection library that is the same as the target production process code, it indicates that the target functional part may be a newly emerged functional part, and the corresponding inspection standard has not been generated yet. It should be understood that different functional parts in the same functional block have the same function, and the inspection standards for different functional parts in this functional block often have commonalities, so the inspection standards can be applied to each other. Therefore, the target inspection standard can be determined according to the function code of the functional block where the target functional part is located, that is, all other production process codes corresponding to the function code except the target production process code are found, and then the target inspection standard for the target functional part is determined according to all other production process codes.

[0082] Further, in one embodiment, determining the target inspection standard based on all other production process codes includes:

[0083] For each other production process code, determine the corresponding other inspection process code from the inspection library;

[0084] Take the inspection standards corresponding to all other inspection process codes as the target inspection standard.

[0085] Exemplarily, in this embodiment, for a target functional part for which the inspection standard has not been generated, the target inspection standard for the target functional part can be determined through the inspection standards of other functional parts in its functional block. Specifically, first determine all other production process codes except the target production process code according to the function code of the target functional part, then determine the corresponding other inspection process codes from the inspection library for each other production process code, and finally take the inspection standards corresponding to all other inspection process codes as the target inspection standard.

[0086] For example, the target functional part 55, as a new functional part, is located in the functional block 5 with the function code Z5, and the functional block 5 includes functional parts 51 to 55. The part codes corresponding to functional parts 51 to 55 are W1, W2, W3, W4, and W5 in sequence, and the production process codes corresponding to part codes W1, W2, W3, W4, and W5 are P1, P2, P3, P4, and P5 in sequence. Assume that no inspection process code the same as P5 is found in the inspection library. Then, through the coding mapping relationship library, find the part codes W1 to W4 corresponding to the function code Z5, screen out the production process codes P1 to P4 corresponding to part codes W1 to W4 respectively, then find the inspection process codes P1 to P4 through the inspection library, and finally take all the inspection standards corresponding to the inspection process codes P1 to P4 as the target inspection standard for the target functional part 55.

[0087] Step S30: Perform quality control on the target functional part through the target production process code and the target inspection standard.

[0088] Exemplarily, in this embodiment, after determining each target production process code and its corresponding target inspection standard, the corresponding target inspection standard can be executed on the target production process corresponding to the target functional component to achieve quality control of the target functional component. For example, if the target functional component is an instrument panel, the name of its production process is "install instrument panel assembly" and the production process code is GX111, then its inspection process code is also GX111, making the inspection process affiliated with the production process; therefore, when the instrument panel is at the production process corresponding to the production process code GX111, it indicates that after completing this production process, it will enter the inspection process with the inspection process code GX111 to execute the inspection standard corresponding to the inspection process code GX111, thereby achieving quality control of the instrument panel.

[0089] It can be seen that in this embodiment, the encoding mapping relationship library storing the mapping relationship between the part code of the functional component, the function code of the functional group block where the functional component is located, and the production process code is used to determine the target production process code corresponding to the target part code of the target functional component. Then, according to the principle that there is a corresponding inspection process code for the inspection standard and the inspection process code is the same as the production process code, the target inspection standard corresponding to the target production process code can be determined. Finally, through the target production process code and the target inspection standard, the quality control of the target functional component can be automatically carried out without the need to arrange the inspection form and determine the inspection timing, etc., effectively improving the control efficiency of product quality.

[0090] Further, in one embodiment, the method further includes:

[0091] When it is detected that the process problem control database contains a new problem description, a new inspection standard is determined based on the new problem description, where the new problem description is used to describe a new quality problem that occurs to the target functional component at the process corresponding to the target production process code;

[0092] Taking the target production process code as the inspection process code of the new inspection standard to establish a mapping relationship between the new problem description and the target production process code, and adding the new problem description and the new inspection standard to the recurrence prevention database.

[0093] Exemplarily, in this embodiment, the process where the problem occurs is locked with respect to the current production problem data generated in real-time production, and a relationship of attachment is formed therewith, thereby forming a one-dimensional table for process problem control as shown in Table 1, and forming a spot check item in the current production process and entering the recurrence prevention database to track and confirm whether it recurs. For example, during the production process coded as GX112, a new problem of "the sub-meter and the storage box do not fit together and there is a large gap" occurs. The new problem description in the process problem control database is "the sub-meter and the storage box do not fit together and there is a large gap", and the corresponding inspection item (i.e., the new inspection standard) is "no gap, tight fit", and the production process is coded as GX112 as the inspection process code of the inspection item to establish a mapping relationship between the new problem description and the target production process code, even if the inspection item is automatically attached to GX112, and the above new problem description and its corresponding new inspection standard are added to the recurrence prevention database; it can be understood that "the sub-meter and the storage box do not fit together and there is a large gap" is a problem phenomenon, and "no gap, tight fit" is an inspection standard or item.

[0094] Table 1 One-dimensional table of process problem control

[0095]

[0096] Specifically, in order to implement the above solution, we can first define the process set, problem phenomenon set and inspection standard set, such as the process set: P = {GX111, GX123, ...}, where each element represents a production process; the problem phenomenon (i.e., problem description) set: Q = {"instrument panel gap surface difference exceeds tolerance", "screws are not tightened", ...}, where each element describes a specific problem phenomenon; the inspection standard set: S = {"is the instrument panel gap surface difference out of tolerance", "are the screws tightened", ...}, where each element is an inspection standard or item for the problem phenomenon.

[0097] Then, mapping definitions are performed, such as (1) mapping of problem phenomena to inspection standards: f:Q→S, where each problem phenomenon is mapped to the corresponding inspection standard through the function f, for example, f("dashboard gap surface difference exceeds tolerance") = "is the dashboard gap surface difference exceeding tolerance"; (2) mapping of process to problem phenomenon (dynamically generated): in the real-time production process, this mapping is dynamically constructed, because the association from the production process to the problem phenomenon is established only when a problem actually occurs in the production process.

[0098] Assume that there is a temporary mapping set M to record the above mapping relationship, then each element is a triple (p, q, s), which indicates that a problem phenomenon q∈Q has occurred in the production process p∈P and should be attached to the inspection standard s∈S; specifically, whenever the problem phenomenon q occurs in the production process p, the corresponding inspection standard will be found through the mapping f (that is, s=f(q)), and (p, q, s) will be added to the mapping set M, that is, this relationship is recorded in the mapping set M, so that in subsequent production, for each production process p, all entries (p, q, s) related to p in the mapping set M need to be traversed to display the inspection standard s as the inspection item of the production process p.

[0099] It can be seen that the problem data appearing in the upstream and downstream production lines can be automatically entered into the database and form inspection standards, so that in the subsequent production, the corresponding inspection standards and problem phenomenon descriptions will automatically appear when the corresponding process is produced, eliminating the transmission process and effectively improving the response efficiency.

[0100] Furthermore, in one embodiment, the method further includes:

[0101] For each target problem description in the recurrence prevention database, when it is detected that the number of times the target problem description has not occurred in the process of the first production process code corresponding to it is greater than the preset number threshold, the target problem description and its corresponding first inspection standard will be removed from the recurrence prevention database, and the mapping relationship between the first inspection process code corresponding to the first inspection standard and the first production process code will be released.

[0102] By way of example, it is understandable that the recurrence prevention database cannot be updated with the iterative updates of the product, so that outdated data cannot be cleared out of the database. If past problem data is only entered but not exited, then the data will only increase, which is not conducive to data management and will take up too much memory. Therefore, this embodiment will establish a return rule, that is, when a certain problem phenomenon continues for a period of time during the production inspection process without recurrence, it will be removed from the database.

[0103] Specifically, a spot check result record can be maintained for each combination of production process p and problem phenomenon q, which can be a continuous spot check result sequence or simplified to the status of a final spot check result (such as "OK", "NG"); then create spot check and destocking logic: at each spot check, check the spot check result of the problem phenomenon q in the recurrence prevention database in the production process p. If the spot check results are all "not occurred" (or meet other defined "no recurrence" conditions) within a period of time (such as N consecutive spot checks, that is, N is a preset number of times, and its specific value can be determined according to actual needs), then the problem phenomenon q is removed from the monitoring list of the current production process p, that is, the problem phenomenon q and its corresponding spot check standard are removed from the recurrence prevention database, and the mapping relationship between the spot check process code p corresponding to the spot check standard and the production process code p is released. In other words, the production process code p is no longer used as the spot check process code of the spot check standard. It can be seen that this embodiment is conducive to the timely update of enterprise standards, so that inapplicable standards can be quickly removed and cleaned up.

[0104] In summary, this embodiment is applicable to similar products whose functions and systems are highly similar (such as the suspension system and power system of a car, as long as it is a car, it has these functional components). It uses different functions as the division principle to decompose and refine the standard file in a scenario-based manner, that is, different functional parts correspond to different standards, so that the origin and destination of the standard are simple and clear. For the situation where product iterations are fast and the quality control measures for R&D products are unclear, the layout and implementation of quality control can be quickly realized, which is faster than manual review and identification; and the production line processes are arranged in a hanging relationship, that is, the production process and the quality inspection process are in a hanging relationship. In other words, the production process is hung under the quality inspection process; in addition, this embodiment also establishes return rules and updates the database in real time according to thresholds to facilitate the timely updating of enterprise standards, so that new standards can be quickly established, and inapplicable standards can be quickly removed and cleaned up.

[0105] In a second aspect, an embodiment of the present application also provides a product quality control device.

[0106] In one embodiment, referring to Figure 4 , Figure 4 This is a functional module diagram of an embodiment of the product quality control device of this application. Figure 4 As shown, the product quality control device includes:
