[0032] Figure 1 The following schematically shows a flow chart of a material inspection method according to an embodiment of the present application. Figure 1 As shown, in one embodiment of the present application, a material inspection method is provided, comprising the following steps:

[0033] Step 101: Obtain tasks to be inspected for a batch of materials. The tasks to be inspected include inspection standards and inspection quantities of the batch of materials. The inspection standards include sampling level values ​​and sampling standards. The sampling standards include target sampling plans.

[0034] For a batch of materials, the processor can obtain the tasks to be inspected for the batch of materials. Among them, the tasks to be inspected include the inspection standards and inspection quantity of the batch materials, the inspection standards include the sampling level value and the sampling standards, and the sampling standards include the target sampling scheme. In an embodiment of the present application, the sampling standards include the GB2828 sampling standards and / or the American standard zero-defect sampling standards. The sampling standards may also include a fixed sampling quantity standard and a fixed sampling ratio standard. The target sampling scheme includes a normal sampling scheme, a relaxed sampling scheme, a strict sampling scheme, and an inspection-free sampling scheme. The target sampling scheme is used to characterize the severity of the sampling under the sampling standard.

[0035] Step 102: Match the inspection code value corresponding to the inspection quantity and the sampling level value from the preset sample size code table.

[0036] The processor can match the inspection code value corresponding to the inspection quantity and sampling level value from the preset sample quantity code table. Among them, the preset sample quantity code table includes multiple preset quantity intervals and multiple preset sampling level values, and each preset quantity interval and each preset sampling level value corresponds to a preset code value. Among them, the value of the sample quantity code table can be based on the GB2828 standard or the American standard zero defect standard, and the upper and lower limits of different sampling quantity intervals and the size of the sampling and acceptance values ​​can be adjusted in combination with the actual production progress and production quality of the factory. Among them, when the factory purchases a large number of raw materials and the quality inspectors have more inspection tasks, the sampling number n can be appropriately reduced to reduce the number of random inspections required by the quality inspectors. When the quality of the raw materials purchased by the factory is poor, the sampling number n can be appropriately increased while reducing the acceptance value Ac to increase the proportion of random inspections and judgment requirements to ensure the quality of the raw materials. On the contrary, the sampling number n can be reduced.

[0037] When matching the inspection word code value corresponding to the inspection quantity and the sampling level value, the processor can determine the preset number interval matching the inspection quantity and the preset sampling level value matching the sampling level value. Afterwards, the preset word code value corresponding to the matched preset number interval and the preset sampling level value can be determined as the inspection word code value.

[0038] Step 103: Determine the sampling quantity and sampling acceptance value of the batch material under the target sampling plan according to the inspection code value and the sampling level value.

[0039] Different target sampling schemes correspond to different sampling quantities and sampling acceptance values. The processor can determine the sampling quantity and sampling acceptance value of the batch material under the target sampling scheme according to the inspection code value and the sampling level value. Specifically, a relationship table under different sampling schemes can be constructed in advance, and the relationship table defines the preset code value and the preset sampling level value, and the relationship between the preset sampling quantity and the preset sampling acceptance value. Among them, different degrees of sampling schemes can be based on the GB2828 standard or the American standard zero defect standard, and the upper and lower limits of different sampling quantity intervals and the size of the sampling and acceptance values ​​can be adjusted in combination with the actual production progress and production quality of the factory. Among them, when the factory purchases a large number of raw materials and the quality inspectors have more inspection tasks, the sampling number n can be appropriately reduced to reduce the number of inspections required by the quality inspectors. When the quality of the raw materials purchased by the factory is poor, the sampling number n can be appropriately increased while the acceptance value Ac can be reduced to increase the proportion of random inspections and judgment requirements to ensure the quality of the raw materials. On the contrary, the sampling number n can be reduced.

[0040] After obtaining the inspection code value and the sampling level value, the preset code value corresponding to the inspection code value and the preset sampling level value corresponding to the sampling level value can be matched based on the relationship table corresponding to the target sampling plan. Afterwards, the preset sampling quantity and the preset sampling acceptance value corresponding to the matched preset code value and the preset sampling level value can be used as the sampling quantity and sampling acceptance value of the batch material under the target sampling plan.

[0041] Step 104: sampling a sampling quantity of materials from the batch material, and inspecting the sampled materials according to the target sampling plan to obtain the sampling unqualified quantity of the batch material.

[0042] Step 105: Determine the inspection result of the batch material based on the sampling rejection quantity and the sampling acceptance value.

[0043] The processor can extract a sampling quantity of materials from the batch material, and inspect the extracted materials according to the target sampling plan to obtain the sampling unqualified quantity of the batch material. The processor can compare the sampling unqualified quantity with the sampling acceptance value to obtain the inspection result of the batch material.

[0044] In an embodiment of the present application, determining the inspection result of a batch material based on the number of unqualified sampling and the sampling acceptance value includes: when the number of unqualified sampling is greater than the sampling acceptance value, determining the inspection result of the batch material is unqualified; when the number of unqualified sampling is less than or equal to the sampling acceptance value, determining the inspection result of the batch material is qualified.

[0045] When the number of unqualified samples is greater than the sampling acceptance value, it can be said that the number of unqualified samples in the batch is too large, and the processor can determine that the inspection result of the batch is unqualified. When the number of unqualified samples is less than or equal to the sampling acceptance value, it can be said that the number of unqualified samples in the batch is within a reasonable range, and the processor can determine that the inspection result of the batch is qualified.

[0046] In an embodiment of the present application, the method also includes: after determining the inspection results of the batch material, judging whether the rule transfer conditions for transferring the target sampling scheme to another sampling scheme are met; if the rule transfer conditions are met, the target sampling scheme of other uninspected batch materials of the same type as the batch material is transferred to another sampling scheme.

[0047] After determining the inspection result of the batch of materials, the processor can determine whether the rule transfer condition for transferring the target sampling scheme to another sampling scheme is met. If the rule transfer condition is met, the processor can transfer the target sampling scheme of other uninspected batch materials of the same type as the batch material to another sampling scheme. When inspecting other uninspected batch materials, the transferred sampling scheme, i.e., another sampling scheme, can be used to achieve flexible configuration of the sampling scheme and improve the accuracy of material inspection.

[0048] In an embodiment of the present application, determining whether a rule transfer condition for transferring a target sampling scheme to another sampling scheme is met includes: when the target sampling scheme is a preset sampling scheme, obtaining historical inspection results of other inspected batch materials of the same type as the batch material; and determining whether a rule transfer condition for transferring the target sampling scheme to another sampling scheme is met based on the inspection results and the historical inspection results.

[0049] When the target sampling scheme is a preset sampling scheme, the processor can obtain historical inspection results of other inspected batches of materials of the same type as the batch material. The preset sampling scheme includes a normal sampling scheme, a relaxed sampling scheme, and a strict sampling scheme. The sampling standards used in the historical inspection results may include but are not limited to the GB2828 sampling standard and the American standard zero defect sampling standard, as well as a fixed sampling ratio standard and a fixed sampling quantity standard.

[0050] The processor can determine whether the rule transfer condition for transferring the target sampling scheme to another sampling scheme is met based on the inspection results and historical inspection results. For example, if the target sampling scheme is a normal sampling scheme, the sampling schemes to which it can be transferred may include a strict sampling scheme, a relaxed sampling scheme, and an inspection-free sampling scheme. If the target sampling scheme is a relaxed sampling scheme, the sampling schemes to which it can be transferred may include a normal sampling scheme. If the target sampling scheme is a strict sampling scheme, the sampling schemes to which it can be transferred may include a normal sampling scheme.

[0051] In an embodiment of the present application, the preset sampling scheme includes a normal sampling scheme, and judging whether the rule transfer condition for transferring the target sampling scheme to another sampling scheme is satisfied according to the inspection results and the historical inspection results includes: when the target sampling scheme is the normal sampling scheme, judging whether there are batches of materials whose inspection results are unqualified for consecutive times reaching a first value according to the inspection results and the historical inspection results; when there are batches of materials whose inspection results are unqualified for consecutive times reaching the first value, determining that the rule transfer condition for transferring the target sampling scheme to the strict sampling scheme is satisfied; when there are batches of materials whose inspection results are unqualified for consecutive times reaching the first value, judging whether the rule transfer condition for transferring the target sampling scheme to the strict sampling scheme is satisfied according to the inspection results. Based on the historical inspection results, determine whether there are batches of materials whose inspection results are qualified for a consecutive number of times reaching the first value; if there are batches of materials whose inspection results are qualified for a consecutive number of times reaching the first value, determine whether there are batches of materials whose inspection results are qualified for a consecutive number of times reaching the second value based on the inspection results and the historical inspection results; if there are no batches of materials whose inspection results are qualified for a consecutive number reaching the second value, determine that the rule transfer conditions for transferring the target sampling scheme to the relaxed sampling scheme are met; if there are batches of materials whose inspection results are qualified for a consecutive number reaching the second value, determine that the rule transfer conditions for transferring the target sampling scheme to the inspection-exempt sampling scheme are met.

[0052] The preset sampling scheme includes a normal sampling scheme. When the target sampling scheme is a normal sampling scheme, the processor can determine whether there are batches of materials whose inspection results are unqualified for consecutive times reaching the first value based on the inspection results and historical inspection results. Among them, the first value can be set based on the actual situation. For example, the first value can be set to 5. In the case that there are batches of materials whose inspection results are unqualified for consecutive times reaching the first value, it can be explained that the supply quality of the supplier of the material has developed from good to poor at this time, and the processor can determine whether the rule transfer conditions for transferring the target sampling scheme to the strict sampling scheme are met. At this time, the target sampling scheme of other uninspected batches of materials of the same type as the batch material can be transferred to the strict sampling scheme. When inspecting other uninspected batches of materials later, the target sampling scheme adopted can be set to the strict sampling scheme.

[0053] In the case that there is no batch material whose inspection results are unqualified for consecutive times reaching the first value, the processor can determine whether there is a batch material whose inspection results are qualified for consecutive times reaching the first value according to the inspection results and historical inspection results. In the case that there is a batch material whose inspection results are qualified for consecutive times reaching the first value, for the accuracy of subsequent inspections, the processor can determine whether there is a batch material whose inspection results are qualified for consecutive times reaching the second value according to the inspection results and historical inspection results. The second value can be set based on actual conditions, and the second value can be set to be larger than the first value. For example, the second value can be set to 10.

[0054] In the case that there is no batch material whose inspection results are qualified for the consecutive times reaching the second value, it can be explained that the supply quality of the supplier of the material has developed from good to poor at this time, and the acceptance standard of the material can be appropriately relaxed. The degree of relaxation in this case is small, and the processor can determine that the rule transfer conditions for transferring the target sampling scheme to the relaxed sampling scheme are met. At this time, the target sampling scheme of other uninspected batch materials of the same type as the batch material can be transferred to the relaxed sampling scheme. When inspecting another uninspected batch material later, the target sampling scheme used can be set to the relaxed sampling scheme.

[0055] In the case where there are batches of materials whose inspection results are qualified for consecutive times reaching the second value, it can be explained that the supply quality of the supplier of the material has developed from good to excellent, and the acceptance standard of the material can be appropriately relaxed. The relaxation degree in this case is relatively large, and the processor can determine that the rule transfer conditions for transferring the target sampling scheme to the inspection-free sampling scheme are met. At this time, the target sampling scheme of other uninspected batches of materials of the same type as the batch material can be transferred to the inspection-free sampling scheme. When inspecting another uninspected batch of materials later, the target sampling scheme used can be set as the inspection-free sampling scheme.

[0056] In an embodiment of the present application, the preset sampling scheme includes a relaxed sampling scheme, and judging whether the rule transfer condition for transferring the target sampling scheme to another sampling scheme is met according to the inspection results and the historical inspection results includes: when the target sampling scheme is a relaxed sampling scheme, judging whether there is a batch of materials whose inspection results are unqualified for a consecutive number of times reaching a first value according to the inspection results and the historical inspection results; when there is a batch of materials whose inspection results are unqualified for a consecutive number of times reaching the first value, determining whether the rule transfer condition for transferring the target sampling scheme to the normal sampling scheme is met.

[0057] The preset sampling scheme includes a relaxed sampling scheme. When the target sampling scheme is a relaxed sampling scheme, the processor can determine whether there are batches of materials whose inspection results are unqualified for consecutive times reaching a first value based on the inspection results and historical inspection results. The first value can be set based on actual conditions, for example, the first value can be set to 5.

[0058] In the case where there are batches of materials whose inspection results are unqualified for a number of consecutive times reaching the first value, it can be indicated that the supply quality of the supplier of the material has improved from poor to good at this time, and the processor can determine that the rule transfer condition for transferring the target sampling scheme to the normal sampling scheme is satisfied. At this time, the target sampling scheme of other uninspected batches of materials of the same type as the batch material can be transferred to the normal sampling scheme. When another uninspected batch of materials is subsequently inspected, the target sampling scheme used can be set to the normal sampling scheme.

[0059] In one embodiment, when the target sampling scheme is a relaxed sampling scheme and there is no batch material whose inspection results are unqualified for a consecutive number of times reaching a first value, the target sampling scheme for other uninspected batch materials of the same type as the batch material may not be transferred to another sampling scheme.

[0060] In an embodiment of the present application, the preset sampling scheme includes a strict sampling scheme, and judging whether the rule transfer condition for transferring the target sampling scheme to another sampling scheme is met according to the inspection results and the historical inspection results includes: when the target sampling scheme is a strict sampling scheme, judging whether there is a batch of materials whose inspection results are qualified for a consecutive number of times reaching a first value according to the inspection results and the historical inspection results; when there is a batch of materials whose inspection results are qualified for a consecutive number of times reaching the first value, determining whether the rule transfer condition for transferring the target sampling scheme to the normal sampling scheme is met.

[0061] The preset sampling scheme includes a strict sampling scheme. When the target sampling scheme is a strict sampling scheme, the processor can determine whether there is a batch of materials whose inspection results are qualified for a continuous number of times reaching a first value based on the inspection results and historical inspection results. The first value can be set based on actual conditions, for example, the first value can be set to 5.

[0062] In the case where there are batches of materials whose inspection results are qualified for a continuous number of times reaching the first value, it can be indicated that the supply quality of the supplier of the material has developed from poor to good at this time, and the processor can determine that the rule transfer condition for transferring the target sampling scheme to the normal sampling scheme is satisfied. At this time, the target sampling scheme of other uninspected batches of materials of the same type as the batch material can be transferred to the normal sampling scheme. When inspecting another uninspected batch of materials later, the target sampling scheme used can be set to the normal sampling scheme.

[0063] In one embodiment, when the target sampling scheme is a strict sampling scheme and there is no qualified inspection result of batch materials that has not reached a first value for a consecutive number of times, the target sampling scheme of other uninspected batch materials of the same type as the batch material may not be transferred to another sampling scheme.

[0064] In an embodiment of the present application, determining whether a rule transfer condition for transferring a target sampling scheme to another sampling scheme is met includes: when the target sampling scheme is an inspection-free sampling scheme, determining whether there are historical quality complaint reports and production quality feedback reports for materials of the same type as the batch material, and obtaining a production work order scheduling report for materials of the same type as the batch material; determining whether a rule transfer condition for transferring the target sampling scheme to another sampling scheme is met based on the determination result of whether a historical quality complaint report exists, the determination result of whether a production work order scheduling report exists, and the production quality feedback report.

[0065] When the target sampling scheme is not a preset sampling scheme, that is, the target sampling scheme is an inspection-free sampling scheme, the processor can determine whether there are historical quality complaint reports and production quality feedback reports for materials of the same type as the batch material, and obtain a production work order scheduling report for materials of the same type as the batch material.

[0066] Among them, the historical quality complaint report defines the quality complaints of materials of the same type as the batch materials. The production quality feedback report defines the quality of the materials of the same type as the batch materials. The production work order scheduling report defines the schedule for the production of materials of the same type as the batch materials.

[0067] The processor can determine whether the rule transfer conditions for transferring the target sampling plan to another sampling plan are met based on the judgment result of whether the historical quality complaint report exists, the judgment result of whether the production work order scheduling report exists, and the production quality feedback report.

[0068] In an embodiment of the present application, judging whether the rule transfer conditions for transferring the target sampling scheme to another sampling scheme are met based on the judgment result of whether a historical quality complaint report exists, the judgment result of whether a production work order scheduling report exists, and the production quality feedback report includes: when the target sampling scheme is an inspection-free sampling scheme, judging whether the number of consecutive days without producing materials of the same type as the batch material reaches a third value based on the production work order scheduling report; when there are historical quality complaint reports and production quality feedback reports, and the number of consecutive days without producing materials of the same type as the batch material reaches a third value, determining that the rule transfer conditions for transferring the target sampling scheme to the normal sampling scheme are met.

[0069] In the case where the target sampling scheme is an inspection-free sampling scheme, the processor can determine whether the number of consecutive days reaches a third value without producing materials of the same type as the batch material based on the production work order scheduling report. Among them, the third value can be set according to the actual situation. For example, the third value can be 60, that is, 3 months. In the case where there are historical quality complaint reports and production quality feedback reports, and the number of consecutive days reaches the third value without producing materials of the same type as the batch material, it can be said that the supply quality of the supplier of the material has developed from good to good at this time, and the processor can determine that the rule transfer conditions for transferring the target sampling scheme to the normal sampling scheme are met. At this time, the target sampling scheme of other uninspected batch materials of the same type as the batch material can be transferred to the normal sampling scheme. When inspecting other uninspected batch materials later, the target sampling scheme used can be set to the normal sampling scheme.

[0070] The above technical scheme, after determining the inspection results of the batch materials, determines whether the rule transfer conditions for transferring the target sampling scheme to another sampling scheme are met; when the rule transfer conditions are met, the target sampling scheme of other uninspected batch materials of the same type as the batch materials is transferred to another sampling scheme, thereby realizing dynamic configuration of the sampling scheme and making material inspection more reasonable.

[0071] like Figure 2 As shown, a flow chart of another material inspection method is provided.

[0072] When inspecting incoming materials, the inspection quantity of the incoming materials can be obtained, and a row of data in the sample size code table can be matched according to the inspection quantity, and the sample size code can be obtained based on the row of data and the sampling level value configured in the inspection standard. The sampling quantity n and the acceptance number Ac of the incoming materials are determined based on the sampling plan of the incoming materials, the sample size code, and the sampling level value configured in the inspection standard. After that, the inspection is carried out based on the sampling quantity n and the acceptance number Ac to obtain the number of sampling failures of the incoming materials, and the inspection report of the incoming materials is generated based on the number of sampling failures. After that, it can be judged whether the rule transfer conditions are met according to the rule transfer plan. If so, the corresponding rule transfer is carried out, and the next sampling inspection is carried out according to the sampling plan after the transfer.
