These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0068] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.
[0069] First, the terms involved in this application are explained:
[0070] Process ID is used to indicate the unique identity of the process.
[0071] Quality standard data refers to the production standard of a process, which is used to measure the quality of semi-finished products produced by the process. Semi-finished products refer to target objects that have not completed all processing steps.
[0072] Quality inspection data refers to one or more quality inspection data of semi-finished products produced when the process is completed.
[0073] Workshop ID is used to indicate the unique identity of a workshop. Each workshop is used to perform one or more processes.
[0074] Process evaluation data is used to indicate the degree to which the process capability of the process executed in the workshop meets the product quality standard requirements (specification range, etc.). Process evaluation data can be used to determine the degree of process stability and the trend of process stability changes over a period of time.
[0075] The process evaluation data includes the process capability evaluation value and the process performance evaluation value. The process capability evaluation value is used to indicate the ability of the product to meet the standards and specifications during the process, and the process performance evaluation value is used to indicate the ability of the product to meet the standards and specifications after the process is completed.
[0076] The process capability assessment value can also be called the process capability index, which refers to the actual processing capability of the process performed by the production equipment in the workshop under a controlled state (stable state) for a certain period of time.
[0077] The process refers to the comprehensive effect of five basic quality factors, namely, the operator, workshop production equipment, processing raw materials, processing methods, and workshop production environment, that is, the production process of the product.
[0078] The existing method of evaluating product quality usually involves users collecting quality inspection data of the processing procedures, and the users calculating the process stability of the processing procedures based on the quality inspection data to determine the quality of the product.
[0079] The above method is too dependent on manual labor and requires a large amount of manpower, which makes the calculation process time-consuming and the stability of the calculation results is low. The product production quality cannot be accurately assessed based on the calculation results, making the product production quality unstable.
[0080] In view of the above problems, the embodiment of the present application proposes a quality improvement method, device and electronic device based on process stability. The method includes: obtaining process information of multiple processes of a target object, collecting multiple sets of process quality detection data of each workshop in at least one workshop associated with each process in the first preset time period at intervals of a first preset time period, and calculating the process evaluation data of each process in each associated workshop according to the quality standard data of each process and the multiple sets of process quality detection data of each workshop associated with each process. According to the process evaluation data of each process in each associated workshop, the quality improvement measures of each workshop associated with each process are determined respectively. In this way, the process evaluation data of each process in each associated workshop can be calculated according to the process quality detection data and the corresponding quality standard data of each process in each associated workshop, so as to determine the quality improvement measures corresponding to each workshop, improve the accuracy and calculation efficiency of the evaluation data, and propose targeted quality improvement measures for different workshops to improve the process stability of each workshop, thereby improving the quality and production stability of the target object.
[0081] The quality improvement method based on process stability provided in this application can be applied to Figure 1 The schematic diagram of the quality improvement system architecture based on process stability is shown in Figure 1. Figure 1 As shown, the quality improvement system based on process stability includes: electronic equipment and production equipment in multiple workshops ( Figure 1 Only two are shown, namely, production equipment 1 in workshop 1 and production equipment 2 in workshop 2). The electronic equipment is respectively connected to each production equipment for communication.
[0082] Among them, the production equipment in the workshop is used to execute one or more processes of the target object. The electronic device can collect multiple groups of process quality inspection data of each workshop in at least one workshop associated with each process within the first preset time period at intervals of the first preset time period, and calculate the process evaluation data of each process in each workshop associated with each process according to the quality standard data and quality inspection data of each process. According to the process evaluation data of each process in each workshop associated with each process, the quality improvement measures of each workshop associated with each process are determined respectively. And corresponding instructions or information are sent to the production equipment of each workshop based on the quality improvement measures.
[0083] The above-mentioned electronic devices may include mobile phones, PCs, tablet computers and other devices, which are not specifically limited here.
[0084] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.
[0085] Figure 2 This is a flow chart of a quality improvement method based on process stability provided in an embodiment of the present application. Figure 2 , the quality improvement method based on process stability includes the following steps:
[0086] S101. Acquire process information of multiple processes of a target object; wherein the process information includes quality standard data.
[0087] Specifically, the target object refers to a product including multiple processing steps, for example, the target object is a mechanical device, or the target object is a daily chemical product.
[0088] Specifically, the process information of each process in the multiple processes of the target object is obtained, wherein the process information includes but is not limited to quality standard data, and the quality standard data is used to measure the quality of the target object corresponding to the process.
[0089] For example, the daily chemical product is paper towels, and the first process of paper towels is to remove moisture. The corresponding quality standard data is: the moisture content range of the paper towels after dehydration = [0.5%, 2%].
[0090] S102. At intervals of a first preset time period, respectively collect quality inspection data of each process within the first preset time period; wherein the quality inspection data of the process includes multiple groups of process quality inspection data of each workshop in at least one workshop associated with the process.
[0091] Specifically, during the production process of the target object, a quality inspection cycle (hereinafter referred to as the first preset time period) can be pre-set to achieve periodic evaluation of the process stability of each process. The first preset time period can be specifically set according to actual conditions. Exemplarily, the first preset time period is the processing time with the largest value among the processing times of multiple processes. Another exemplary method is that the first preset time period is b times the average duration of multiple processes, where b is an integer greater than 1.
[0092] Specifically, at intervals of a first preset time period, multiple groups of process quality inspection data of each workshop in at least one workshop associated with each process within the first preset time period are collected respectively as the quality inspection data of each process within the first time period. The processing time of each process is less than the first preset time period, and correspondingly, the process quality inspection data collected in each workshop within the first time period includes multiple groups.
[0093] It is understandable that the production equipment of each workshop can be used to perform one or more processes, and each process can be completed by the production equipment of one or more workshops. Therefore, the quality inspection data of the same process includes multiple sets of process quality inspection data of each workshop in at least one workshop associated with the process.
[0094] Still taking the target object as paper towels and the process as dehydration as an example, the corresponding process quality detection data is the moisture content. At least one workshop associated with the dehydration process is CJ001, CJ002, and CJ003, and the quality detection data of dehydration includes the moisture content of paper towels in workshop CJ001, the moisture content of paper towels in workshop CJ002, and the moisture content of paper towels in workshop CJ003.
[0095] S103, calculating and obtaining process evaluation data of each process in each workshop associated with each process according to the quality standard data and the quality inspection data of each process.
[0096] Specifically, based on the quality standard data of each process and the periodically collected process quality inspection data of each workshop in at least one workshop associated with each process, the process evaluation data of each process in each workshop associated with each process within each cycle is periodically calculated.
[0097] It can be understood that when the cycle of each workshop is the first preset time period, the process evaluation data of each process in each workshop associated with it within the first preset time period can be calculated based on the quality inspection data of each process collected within the first preset time period.
[0098] It can be understood that when the cycles of each process are different, the process evaluation data of each process in each cycle in each workshop associated with it can be calculated based on the quality inspection data of each process collected in the cycle corresponding to each process.
[0099] Still taking the target object as paper towels and the process as moisture removal as an example, based on the quality inspection data of the moisture removal process within the first preset time period: the moisture content of paper towels in CJ001, the moisture content of paper towels in CJ002, and the moisture content of paper towels in CJ003, and the quality standard data of the moisture removal process: the moisture content range [0.5%, 5%], the process evaluation data of the moisture removal process in the CJ001 workshop, the process evaluation data in the CJ002 workshop, and the process evaluation data in the CJ003 workshop within the first preset time period are calculated respectively.
[0100] S104. Determine quality improvement measures for each workshop associated with each process according to process evaluation data of each process in each workshop associated with each process.
[0101] Specifically, according to the comparison result of the process evaluation data of each process in each workshop associated with each process and the preset threshold, the quality improvement measures corresponding to each workshop associated with each process are determined respectively to improve the process stability of each workshop. The preset threshold includes a first threshold, a second threshold, a third threshold and / or a fourth threshold.
[0102] Figure 3 This is a flow chart of step S103 of the quality improvement method based on process stability provided in the embodiment of the present application. Figure 3 , step S103 of the method comprises the following steps:
[0103] S1031, traversing each of the processes as a target process;
[0104] S1032, determining at least one workshop associated with the target process according to the workshop identifier of the target process, and traversing the at least one workshop associated with the target process to identify each workshop as an associated workshop;
[0105] Specifically, the process information also includes a workshop identification. Each process of the target object is traversed as a target process. According to the workshop identification of the target process, at least one workshop associated with the target process is matched among all workshops associated with the target object, and each workshop in the at least one workshop associated with the target process is traversed as an associated workshop.
[0106] S1033. Calculate process evaluation data of the target process in the associated workshop according to the multiple groups of process quality inspection data of the target process in the associated workshop and the quality standard data of the target process.
[0107] Specifically, based on multiple groups of process quality inspection data of the target process in the associated workshop and the quality standard data of the target process, the process evaluation data of the target process in the associated workshop associated with the target process is calculated, thereby obtaining the process evaluation data of each process in each workshop associated with each process.
[0108] In some embodiments, the process evaluation data includes a process capability evaluation value C pk ;
[0109] Correspondingly, the process evaluation data of the target process in the associated workshop is calculated based on the multiple groups of process quality detection data of the target process in the associated workshop and the quality standard data of the target process, including:
[0110] According to multiple groups of process quality inspection data of the target process in the associated workshop, the quality inspection mean value of the target process in the associated workshop is calculated;
[0111] Calculate the first standard deviation of the target process in the associated workshop according to the quality inspection mean of the target process in the associated workshop and the quality inspection data of the target process;
[0112] A process capability evaluation value of the target process in the associated workshop is calculated based on the quality inspection mean value of the target process in the associated workshop, the first standard deviation, and the quality standard data of the target process.
[0113] Specifically, the process capability evaluation value can be used to evaluate the process stability of the workshop under long-term working conditions, and the corresponding first preset time period can be set to a longer time interval. For example, the first preset time period is 100 hours, or the first preset time period is 200 hours.
[0114] Specifically, after the quality inspection data of each process is collected periodically, the process capability evaluation value of each process in each workshop is calculated based on the quality inspection data of each process collected during the period. The data collection and calculation period of each process is described as the first preset time period. Based on multiple groups of process quality inspection data of the target process in the associated workshop associated with the target process during the first preset time period, the quality inspection mean value of the target process in the associated workshop during each first preset time period is calculated. For details, see formula (1):
[0115]
[0116] Wherein, N represents the number of groups of process quality inspection data of the target process in the associated workshop within the first preset time period, x i Represents the i-th group of process quality inspection data of the target process in the associated workshop within the first preset time period.
[0117] Specifically, according to the quality inspection mean of the target process in the associated workshop in each first preset time period and the quality inspection data of the target process, the first standard deviation of the target process in the associated workshop in each first preset time period is calculated, specifically referring to formula (2):
[0118]
[0119] Specifically, according to the upper limit value and lower limit value of the quality standard of the target process, the quality standard data tolerance of the target process is calculated: see formula (3):
[0120] T=|T u -TL |, where T u Indicates the upper limit of the quality standard, T L Indicates the lower limit of quality standard.
[0121] Specifically, according to the quality inspection mean, the first standard deviation and the quality standard data tolerance of the target process in the associated workshop in each first time period, the process capability evaluation value of the target process in the associated workshop in each first time period is calculated, see formula (4):
[0122]
[0123] in, M represents the median value of the quality standard data of the target process.
[0124] In some embodiments, the process evaluation data includes a process performance evaluation value (P pk );
[0125] The process evaluation data of the target process in the associated workshop is calculated based on the multiple sets of process quality detection data of the target process in the associated workshop and the quality standard data of the target process, including:
[0126] According to multiple groups of process quality inspection data of the target process in the associated workshop, a second standard deviation of the target process in the associated workshop is calculated;
[0127] A process performance evaluation value of the target process in the associated workshop is calculated based on the second standard deviation of the target process in the associated workshop and the quality standard data of the target process.
[0128] Specifically, according to multiple groups of process quality inspection data of the target process in the associated workshop within the first preset time period, the second standard deviation of the target process in the associated workshop is calculated, see formula (5):
[0129]
[0130] Specifically, after the quality inspection data of each process is periodically collected, the process performance evaluation value of each process in each workshop is calculated according to the quality measurement data of each process collected during the period. The data collection and calculation cycle of each process is described as the first preset time period, and the quality standard tolerance of the target process is calculated according to the upper limit value and the lower limit value of the quality standard of the target process (see formula 3). According to multiple groups of process quality inspection data of the target process in the associated workshop associated with the target process in the first preset time period, the quality inspection mean of the target process in the associated workshop in the first preset time period is calculated. According to the second standard deviation of the target process in the associated workshop in the first preset time period, the median value of the quality standard data of the target process, the tolerance of the quality standard data of the target process and the mean value of the quality inspection, the process performance evaluation value of the target process in the associated workshop is calculated (see formula 4). The process performance evaluation value can be used to evaluate the process stability of the workshop under a shorter working state, and the corresponding first preset time period can be set to a shorter time interval. Exemplarily, the first preset time period is 10h, or the first preset time period is 20h.
[0131] By collecting the quality inspection data of each process in the first preset time period at intervals of the first preset time period, when the process evaluation data is the process performance evaluation value, the first preset time period with a shorter interval is used as a cycle, and the evaluation data of each process in the first preset time period in each associated workshop is periodically calculated, so as to determine the process stability of each workshop in a short time. When the process evaluation data is the process capability evaluation value, the first preset time period with a longer interval is used as a cycle, and the evaluation data of each process in the first preset time period in each associated workshop is periodically calculated, so as to determine the process stability of each workshop in a long time, so that the process stability of each workshop in different time periods and different production conditions can be determined based on different process evaluation data and different inspection cycles, and the changing trend of process stability can be determined, so as to facilitate timely discovery of production problems and improve the production quality of the target object.
[0132] Figure 4 This is a flow chart of step S104 of the quality improvement method based on process stability provided in the embodiment of the present application. Figure 4 , step S104 of the method comprises the following steps:
[0133] S1041. When there is process evaluation data not less than a first threshold value in the process evaluation data in each workshop associated with each of the processes, the process corresponding to the process evaluation data is determined to be the first process, and the workshop corresponding to the process evaluation data is determined to be the first target workshop.
[0134] Specifically, when there is process evaluation data not less than a first threshold value in the process evaluation data in each workshop associated with each process of the target object, the workshop corresponding to the process evaluation data not less than the first threshold value is determined to be the first target workshop, and the process corresponding to the process evaluation data not less than the first threshold value is determined to be the first process, and the process stability of the first process in the first target workshop is determined to be higher.
[0135] S1042, collecting multiple sets of process quality inspection data of the first process in the first target workshop within a second preset time period at intervals of a second preset time period; wherein the interval length of the second preset time period is greater than the interval length of the first preset time period;
[0136] S1043, executing the steps of calculating the process evaluation data of each process in each workshop associated with each process based on the quality standard data and the quality inspection data of each process and the subsequent steps.
[0137] Specifically, the quality inspection period of the first process in the first target workshop (initially the first preset time period) is increased to the second preset time period, and the time interval length of the second preset time period is greater than the interval length of the first preset time period. Correspondingly, at intervals of the second preset time period, multiple groups of process quality inspection data in the first target workshop within the second preset time period are collected, and step S103 and subsequent steps are executed, that is, the second preset time period is used as the quality inspection period, and the number of quality inspections of the first process in the first target workshop is reduced.
[0138] Still taking the target object as paper towels and the process as dehumidification as an example, the processing time for dehumidification is 5 minutes, and the first preset time period is 10 hours. Correspondingly, the moisture content of multiple groups of dehumidified paper towels in workshop A associated with the dehumidification process is obtained every 10 hours. When the evaluation data calculated based on the moisture content of the multiple groups of paper towels within the above 10 hours is not less than the first threshold, the moisture content of multiple groups of dehumidified paper towels in workshop A associated with the dehumidification process is obtained every 24 hours, and the process evaluation data of the dehumidification process in workshop A is calculated based on the moisture content of the multiple groups of paper towels within the above 24 hours.
[0139] In some embodiments, the quality detection data includes an upper quality limit value and a lower quality limit value.
[0140] Before step S1042, step S104 further includes:
[0141] When the process evaluation data of the first process in the first target workshop is not less than a second threshold, determining the upper limit value and the lower limit value of the quality standard of the first process; wherein the second threshold value is greater than the first threshold value;
[0142] Specifically, when the second threshold is greater than the first threshold, and the process evaluation data corresponding to the first target workshop is not less than the second threshold, it is determined that the process stability of the first target workshop is high, and the production quality of the target object can be improved by adjusting the quality inspection standard. The quality inspection standard of the first process associated with the first target workshop is determined, and the quality inspection standard includes the upper limit value of the quality standard and the lower limit value of the quality standard. Among them, the first threshold and the second threshold can be specifically set according to the actual situation. For example, the first threshold is set to 1.33 and the second threshold is set to 1.67.
[0143] Update the upper limit value of the quality standard of the first process to the first standard upper limit value, and update the lower limit value of the quality standard of the first process to the first standard lower limit value; wherein, the first standard upper limit value is smaller than the upper limit value of the quality standard of the first process before updating, and the first standard lower limit value is larger than the lower limit value of the quality standard of the first process before updating.
[0144] Specifically, the upper limit value of the quality standard of the first process is reduced, and the lower limit value of the quality standard of the first process is increased, so as to obtain the updated quality standard data of the process associated with the first target workshop as [lower limit value of the first standard, upper limit value of the first standard]. The upper limit value of the first standard is less than the upper limit value of the quality standard of the first process before the update, and the lower limit value of the first standard is greater than the lower limit value of the quality standard of the first process before the update.
[0145] Still taking the target object as paper towels, and the first process as removing moisture as an example, the corresponding quality standard data is the moisture content interval of the paper towels after removing moisture = [0.5%, 2%). The updated quality standard data is the moisture content interval of the paper towels after removing moisture = [0.8%, 1.5%).
[0146] Figure 5 This is a flow chart of step S104 of the quality improvement method based on process stability provided in the embodiment of the present application. Figure 5 The method step S104 further includes the following steps:
[0147] S1044. When there is process evaluation data that is less than the first threshold and not less than the third threshold in the process evaluation data in each workshop associated with each of the processes, the workshop corresponding to the process evaluation data is determined to be the second process, and the workshop corresponding to the process evaluation data is determined to be the second target workshop.
[0148] Specifically, when there is process evaluation data less than the first threshold and not less than the third threshold in the process evaluation data in each workshop associated with each process, the workshop corresponding to the process evaluation data less than the first threshold and not less than the third threshold is determined as the second target workshop, and the process corresponding to the process evaluation data less than the first threshold and not less than the third threshold is determined as the second process. The third threshold is less than the first threshold. Exemplarily, the first threshold is 1.33 and the third threshold is 1.0.
[0149] S1045. Collect multiple sets of process quality inspection data of the second process in the second target workshop within the third preset time period at intervals of a third preset time period, wherein the third threshold value is less than the first threshold value, and the interval length of the third preset time period is less than the interval length of the first preset time period;
[0150] S1046. Generate a first prompt message and send it to the production equipment of the second target workshop; wherein the first prompt message is used to prompt the user to perform a quality inspection on the production equipment of the second target workshop.
[0151] Specifically, the quality inspection period of the second process in the second target workshop (initially the first preset time period) is reduced to a third preset time period to increase the number of quality inspections. The interval length of the third preset time period is less than the interval length of the first preset time period. For example, the interval length of the first preset time period is 10 hours, and the length of the third preset time period is 3 hours.
[0152] Specifically, the process evaluation data being lower than the third threshold value indicates that the process stability of the second process in the second target workshop is low, and the process stability should be improved to improve the production quality of the target object. Correspondingly, a first prompt message is generated to prompt the user to perform a quality inspection on the production equipment in the second target workshop through the first prompt message, improve the quality of the production equipment, and thus improve the process stability in the workshop.
[0153] S1047, executing the steps of calculating the process evaluation data of each process in each workshop associated with each process based on the quality standard data and the quality inspection data of each process and the subsequent steps.
[0154] Specifically, at intervals of a third preset time period, multiple groups of process quality inspection data of the second process in the second target workshop within the third preset time period are collected, and the above-mentioned step S103 and subsequent steps are executed. The process quality inspection data of the second target workshop is periodically collected with the third preset time period as a cycle, and the process evaluation data of the second process in the second target workshop is calculated to determine the process stability of the second process in the second target workshop.
[0155] In some embodiments, the process evaluation data includes a process performance evaluation value.
[0156] Figure 6 This is a flow chart of step S104 of the quality improvement method based on process stability provided in the embodiment of the present application. Figure 6 After step S1046, the method further includes the following steps:
[0157] S1048. Calculate the process capability assessment value of the second process in the second target workshop based on multiple sets of process quality inspection data of the second process in the second target workshop and the quality standard data of the second process within each fourth preset time period; wherein the interval length of the fourth preset time period is greater than the length of the first preset time period.
[0158] Specifically, the process evaluation data includes a process performance evaluation value. The process capability evaluation value can be used to indicate the process performance evaluation in the workshop at the current moment based on the collected data, and can be used to indicate short-time, small-batch production capacity.
[0159] Based on this, when the process evaluation data is a process performance evaluation value, and the process performance evaluation value is less than the first threshold and not less than the third threshold, it is adjusted to collect multiple groups of process quality inspection data of the second process in the second target workshop within the third preset time period every third preset time period, and then the process capability evaluation value of the second process in the second target workshop within each fourth preset time period can be calculated based on the multiple groups of process quality inspection data of the second process in the second target workshop within each fourth preset time period and the quality standard data of the above-mentioned second process, so as to determine the process stability of the second process in the second target workshop under long-term and continuous production conditions.
[0160] The fourth preset time period has a greater length than the first preset time period, for example, the first preset time period is 20 hours, the fourth preset time period is 240 hours, or the fourth preset time period is 300 days.
[0161] S1049, when the process capability evaluation value of the second process in the second target workshop reaches the first threshold, collecting multiple sets of process quality inspection data of the second process in the second target workshop within the first preset time period at intervals of the first preset time period;
[0162] S10410, executing the steps of calculating the process evaluation data of each process in each workshop associated with each process based on the quality standard data and the quality inspection data of each process and the subsequent steps.
[0163] Specifically, when the process capability evaluation value of the second target workshop reaches the first threshold value within the fourth preset time period, it indicates that the process stability of the second target workshop is relatively high, and the quality inspection cycle can be reduced to the first preset time period. Correspondingly, the process quality inspection data of the second target workshop is collected at intervals of the first preset time period, and the above step S103 and subsequent steps are performed to periodically collect multiple groups of process quality inspection data of the second process in the second target workshop according to the first preset time period as a cycle, and determine the process stability of the second target workshop.
[0164] It is understandable that in the initial process stability assessment and quality improvement process, the processes of each workshop cannot be completely in a stable state. Directly calculating the process capability assessment value of each workshop to determine the quality improvement measures may not match the actual state of the process in the workshop. The process performance assessment value can be determined based on the upper limit value or the lower limit value of the quality standard in the quality annotation data. That is to say, when the process in the workshop is not in a stable state (corresponding to continuous or intermittent sampling), a process performance assessment value with higher accuracy can be calculated. Alternatively, when less quality inspection data is collected, a process performance assessment value with higher accuracy can also be calculated.
[0165] By calculating the process performance evaluation value in a smaller cycle (such as the first preset time period), the state of the process in the workshop in the shorter cycle is determined, and the quality improvement measures corresponding to each workshop are determined (such as reducing the quality inspection cycle to the third preset time period). Then, under the state of continuous production, the process capability evaluation value is calculated in a longer cycle (such as the fourth preset time period), and the processing capacity of the workshop in a stable state after the quality improvement measures can be determined, and then the quality of the target object after the quality improvement measures can be evaluated.
[0166] In some embodiments, after S1045, the method further includes:
[0167] When the process evaluation data of the second process in the second target workshop is less than the fourth threshold value and not less than the process evaluation data of the third threshold value, collecting production inspection data of the target object associated with the second target workshop that completes the multiple processes;
[0168] The production quality of the target object corresponding to the second target workshop is determined according to the product inspection data and the production standard data of the target object.
[0169] Specifically, the fourth threshold is less than the first threshold and greater than the third threshold, for example, the first threshold is 1.33, the third threshold is 0.67, and the fourth threshold is 1.0. When the process evaluation data of the second process in the second target workshop is less than the fourth threshold and greater than the third threshold, it is determined that the process capability of the second process in the second target workshop is insufficient and the process stability is low, and quality inspection should be performed on all processed target objects processed in the second target workshop. The production inspection data of the target objects associated with the second target workshop that have completed the above-mentioned multiple processes are collected, wherein the production inspection data includes quality inspection data corresponding to each process. The production standard data is used to indicate the quality standard data of the target object when production is completed.
[0170] Still taking the target object as paper towel as an example, the production test data is not limited to moisture content, flexibility, thickness, etc. The production standard data includes but is not limited to moisture content range, flexibility range and thickness range.
[0171] Specifically, the production inspection data of the target object that has completed the above-mentioned multiple processes and the production standard data of the target object associated with the second target workshop determine the production quality of the target object corresponding to the second target workshop.
[0172] Figure 7 This is a flow chart of step S104 of the quality improvement method based on process stability provided in the embodiment of the present application. Figure 7 The method step S104 further includes the following steps:
[0173] S10410. When there is process evaluation data less than a third threshold value in the process evaluation data in each workshop associated with each of the processes, the process corresponding to the process evaluation data is determined to be the third process, and the workshop corresponding to the process evaluation data is determined to be the third target workshop.
[0174] Specifically, when there is process evaluation data less than the third threshold value in the process evaluation data of each workshop associated with multiple processes of the target object, the process corresponding to the process evaluation data less than the third threshold value is determined to be the third process, and the workshop corresponding to the process evaluation data less than the third threshold value is determined to be the third target workshop. The process evaluation data less than the third threshold value indicates that the process stability of the third target workshop is low, so that the production equipment of the third target workshop continues to execute the third process, which may cause the quality of the target object to be low.
[0175] S10411. Generate a pause instruction and send it to the production equipment in the third target workshop; wherein the pause instruction is used to control the production equipment in the third target workshop to stop executing the third process.
[0176] Specifically, a pause instruction is generated and sent to the production equipment of the third target workshop, wherein the pause instruction is used to control the production equipment of the third target workshop to stop executing the third process corresponding to the process evaluation data less than the third threshold.
[0177] It can be understood that when the production equipment in the third target workshop stops executing the third process, the operation of collecting process quality inspection data of the third process in the third target workshop can be stopped to reduce the workload of data collection and data calculation and improve calculation efficiency.
[0178] In some embodiments, after generating and sending the pause instruction to the production equipment of the third target workshop, the production inspection data of the target objects associated with the third target workshop and having completed the multiple processes may be collected; the production quality of the target objects in the third target workshop may be determined based on the product inspection data and the production standard data of the target objects, thereby achieving quality inspection of all the processed target objects processed in the third target workshop.

[0182]
[0183] By setting different thresholds, the quality inspection data of the processes in each workshop is automatically collected, and the evaluation data is automatically calculated and compared based on different thresholds, so as to determine the quality improvement measures corresponding to the workshops whose evaluation data reaches different thresholds, reduce manpower consumption, improve the efficiency of data collection and calculation, and improve the accuracy and stability of the evaluation results. In addition, the process stability ability of workshops with poor process stability can be improved in a targeted manner, thereby improving the quality of the target object. At the same time, the change trend of the same process in different workshops can be determined.
