Therefore, the directional terms used are used to illustrate and understand the present invention, but not to limit the present invention. In addition, in the drawings, structures with similar or identical structures are represented by the same reference numerals.

[0022] See also Figure 1 The present invention provides a product inspection method, which can be applied to a product inspection system for inspecting products. The product inspection method includes S110-S120.

[0023] S110, under the control of a first inspection instruction for performing a first inspection on a product, a combination code of the product is obtained, and according to the combination code, it is confirmed whether the product has completed the first inspection.

[0024] In the embodiment of the present invention, in the automated production process, it is necessary to check the quality of the product. For injection molding products, it is necessary to inspect their quality after the first batch of products is produced. Only when the quality inspection is qualified can the batch production link be entered, and the injection molding products that have passed the first inspection can be mass-produced. The product inspection method provided by the present invention is applied to the above-mentioned automated production process, especially for the first inspection of products.

[0025] When the first inspection instruction is received, the combination code of the product is obtained. The first inspection instruction can be triggered by the user or automatically triggered when a certain condition is met. For example, when the production of a product is completed, the system automatically determines whether the product has completed the first inspection. If the first inspection has not been completed, it enters the first inspection stage. The combination code of the product refers to the code used to identify the product, that is, the combination code is used to indicate the uniqueness of the product, so as to ensure that each product produced for the first time can be first inspected to avoid omissions. In addition, the combination code may include one code or multiple codes, that is, the combination code may be composed of a single code or multiple codes, which can be adjusted according to the actual product.

[0026] After obtaining the combination code, confirm whether the product has completed the first inspection based on the combination code. For example, for products that have completed the first inspection, the combination code of the product can be recorded. When there is no code identical to the combination code in the system, the product is deemed to have not completed the first inspection. Alternatively, a unique identifier is given to the product that has completed the first inspection, and the unique identifier is matched with the combination code. When the combination code is obtained, the unique identifier is queried based on the combination code. If a matching unique identifier can be queried, it indicates that the product has completed the first inspection. If the unique identifier is not queried, it indicates that the product has not completed the first inspection.

[0027] S120: If the product has not completed the first inspection, obtain the comprehensive basic information of the product to obtain the first inspection information, and confirm whether the product is qualified according to the first inspection information.

[0028] In an embodiment of the present invention, when the product has not completed the first inspection, the comprehensive basic information of the product is obtained to obtain the first inspection information. The comprehensive basic information of the product may include basic information of production materials, basic information of process requirements, key quality control information and mold abnormal state information. The basic information of production materials, basic information of process requirements, key quality control information and mold abnormal state information can be written into the system by the staff, or can be obtained through sensors, which can be determined by the actual production environment. After obtaining the above four information, you can continue to obtain preset information, and each type of information corresponds to a preset information. For example, the basic information of production materials corresponds to preset basic information of production materials, the basic information of process requirements corresponds to preset basic information of process requirements, the key quality control information corresponds to preset key quality control information, and the mold abnormal state information corresponds to preset mold abnormal state information, wherein the preset basic information of production materials can be obtained from the production order, the preset basic information of process requirements can be obtained from the process card, the preset key quality control information can be obtained from the quality database, and the preset mold abnormal state information can be obtained from the mold management system.

[0029] After obtaining the first inspection information and the preset information, compare the first inspection information and the preset information to confirm whether the product is qualified. For example, if the first inspection information is consistent with the preset information, it indicates that the product is qualified; if not, it is unqualified; or, if the deviation value between the first inspection information and the preset information is within the qualified range, it indicates that the product is qualified; if the deviation value is outside the qualified range, it indicates that the product is unqualified.

[0030] In addition, when the mold is in an abnormal state, the abnormal information prompted by the system can be compared with the actual situation to determine whether the mold is abnormal. If the mold is abnormal, the mold abnormality is recorded and the mold is marked as being in an abnormal state. If the mold is not abnormal, the mold is recorded as being normal and the mold is marked as being in a normal state.

[0031] See also Figure 2 In some embodiments, such as in the present embodiment, the combination code includes a material code and a mold code, and the step S110 may include steps S111-S114.

[0032] S111, obtaining order information corresponding to the product, and confirming whether the first code corresponding to the product in the order information is consistent with the material code;

[0033] S112, if the first code is consistent with the material code, confirm whether the second code corresponding to the product in the order information is consistent with the mold code;

[0034] S113, if the second code is consistent with the mold code, it is determined that the product has completed the first inspection;

[0035] S114: If the first code is inconsistent with the material code or the second code is inconsistent with the mold code, it is determined that the product has not completed the first inspection.

[0036] In an embodiment of the present invention, the combined code may include a material code and a mold code, and the material code and the mold code may be obtained from the order information. When determining whether the product has completed the first inspection, first confirm whether the system has recorded a first code that is consistent with the material code. If the system has recorded a first code that is consistent with the material code, then further determine whether the system has recorded a second code that is consistent with the mold code. If the system has recorded a second code that is consistent with the mold code, then it is confirmed that the product has completed the first inspection. When the system does not record the first code that matches the material code or the second code that matches the mold code, it is confirmed that the product has not completed the first inspection.

[0037] See also Figure 3 In some embodiments, such as in the present embodiment, the product inspection method may include steps S130-S140.

[0038] S130, controlled by a sampling inspection instruction for sampling the product, confirming a target machine tool according to the sampling inspection instruction, and confirming whether the target machine tool has completed the production task;

[0039] S140: If the target machine tool completes the production task, a random inspection is performed on the products produced by the target machine tool.

[0040] In an embodiment of the present invention, injection molding products are usually produced by machine tools. The dispatching system will assign the production task of the day to each machine tool. When the machine tool completes the production task of the day, the products produced by the machine tool on the day can be sampled, that is, the system issues a sampling instruction. When the sampling instruction is received, the machine tool that needs to be sampled is confirmed according to the sampling instruction. During the sampling inspection, each machine tool can be sampled, that is, each machine tool extracts some products for inspection, or some machine tools can be sampled for sampling, and the products produced by the sampled machine tools can be sampled.

[0041] After confirming the machine tool that needs to be inspected, set it as the target machine tool and confirm whether the target machine tool has completed the production task. If the production task is completed, the inspection can be carried out. If the production task is not completed, no inspection is required. When confirming whether the machine tool has completed the production task, the product code assigned by the dispatching system can be used to confirm whether the machine tool has completed the production task. For example, the product code corresponding to the last task assigned by the dispatching system can be obtained. If the product code corresponding to the product currently produced by the machine tool is consistent with the product code corresponding to the last task assigned by the dispatching system, it means that the machine tool has completed the production task for the day.

[0042] See also Figure 4 In some embodiments, such as in the present embodiment, the step S130 may include steps S131-S133.

[0043] S131, obtaining the first inspection order number of the last order of the target machine tool, and confirming the current first inspection order number of the target machine tool;

[0044] S132, if the first inspection order number of the last order is consistent with the current first inspection order number, confirming that the target machine tool has completed the production task;

[0045] S133: If the first inspection order number of the last order is inconsistent with the current first inspection order number, it is confirmed that the target machine tool has not completed the production task.

[0046] In an embodiment of the present invention, after the machine tool completes the production of a product, the system will perform a first inspection on the product and will generate a first inspection order number accordingly. A first inspection order number can be generated for each product code. When the first inspection order number of the machine tool's current first inspection is consistent with the first inspection order number of the last order, it indicates that the machine tool has completed the production task for the day and a random inspection can be performed on the machine tool.

[0047] When the system performs random inspection on the products produced by the machine tools, it can first determine whether each machine tool has completed the production task of the day, and perform random inspection on the machine tools that have completed the production task of the day, that is, perform random inspection on each machine tool one by one.

[0048] See also Figure 5 In some embodiments, such as in this embodiment, step S140 may include steps S141-S142.

[0049] S141, selecting a product from the products produced by the target machine tool and setting it as a random inspection product;

[0050] S142, obtaining comprehensive basic information of the sampled product to obtain sampled inspection information, and confirming whether the product is qualified based on the sampled inspection information.

[0051] In the embodiment of the present invention, when a machine tool completes the production of the production task for the day, it is set as the target machine tool, and the products produced by the target machine tool are confirmed, and then a product is randomly selected from the products produced by the target machine tool and set as the sampling product. The products selected by a target machine tool can be multiple or one, which can be set according to the actual situation.

[0052] After confirming the sampled product, obtain the comprehensive basic information of the sampled product to obtain the sampled information. The comprehensive basic information can also include basic information of production materials, basic information of process requirements, key quality control information and mold abnormal status information. The basic information of production materials, basic information of process requirements, key quality control information and mold abnormal status information can be written into the system by the staff, or obtained through sensors, which can be determined by the actual production environment. After obtaining the sampled information, confirm whether the sampled product is qualified according to the sampled information. If qualified, the qualified data is reported. If unqualified, the data is reported to the system. The system adjusts the production process of the product, that is, adjusts the parameters of the machine tool. When the product is re-produced, the product is tested again. If qualified, the data is reported. If still unqualified, the production process continues to be adjusted until the product is qualified.

[0053] See also Figure 6 In some embodiments, such as in this embodiment, step S142 may include steps S1421-S1422.

[0054] S1421, obtaining sampling inspection information, first inspection information and preset information corresponding to the product;

[0055] S1422: confirm whether the product is qualified according to the random inspection information, the first inspection information and the preset information.

[0056] In the embodiment of the present invention, the preset information is a standard value, and each type of information corresponds to a preset information. For example, the basic information of production materials corresponds to the preset basic information of production materials, the basic information of process requirements corresponds to the preset basic information of process requirements, the key quality control information corresponds to the preset key quality control information, and the abnormal state information of molds corresponds to the preset abnormal state information of molds, wherein the preset basic information of production materials can be obtained from the production order, the preset basic information of process requirements can be obtained from the process card, the preset key quality control information can be obtained from the quality database, and the preset abnormal state information of molds can be obtained from the mold management system. The sampling information is compared with the first inspection information and the preset information respectively. When the deviation is within the qualified range, the product is deemed qualified, and when the deviation is outside the qualified range, the product is deemed unqualified.

[0057] See also Figure 7 The present invention also provides a product inspection system 100, which includes a first inspection task module 10 and a first inspection information acquisition module 20; the first inspection task module 10 is used to generate a first inspection task; the first inspection information acquisition module 20 is used to obtain comprehensive basic information of the product according to the first inspection task to obtain first inspection information.

[0058] Specifically, the first inspection task module 10 is used to generate a first inspection task when the product has not undergone first inspection, so as to facilitate the system to perform first inspection on the product. The first inspection information acquisition module 20 is used to obtain comprehensive basic information of the product that needs to be first inspected according to the first inspection task after the system generates the first inspection task, thereby obtaining the first inspection information, and then the system confirms whether the product is qualified based on the first inspection information.

[0059] For example, when the product has not completed the first inspection, the comprehensive basic information of the product is obtained to obtain the first inspection information. The comprehensive basic information of the product can include basic information of production materials, basic information of process requirements, key quality control information and mold abnormal status information. The basic information of production materials, basic information of process requirements, key quality control information and mold abnormal status information can be written into the system by the staff, or obtained through sensors, which can be determined by the actual production environment. After obtaining the above four information, you can continue to obtain preset information, and each type of information corresponds to a preset information. For example, the basic information of production materials corresponds to preset basic information of production materials, the basic information of process requirements corresponds to preset basic information of process requirements, the key quality control information corresponds to preset key quality control information, and the mold abnormal status information corresponds to preset mold abnormal status information, wherein the preset basic information of production materials can be obtained from the production order, the preset basic information of process requirements can be obtained from the process card, the preset key quality control information can be obtained from the quality database, and the preset mold abnormal status information can be obtained from the mold management system.

[0060] After obtaining the first inspection information and the preset information, compare the first inspection information and the preset information to confirm whether the product is qualified. For example, if the first inspection information is consistent with the preset information, it indicates that the product is qualified; if not, it is unqualified; or, if the deviation value between the first inspection information and the preset information is within the qualified range, it indicates that the product is qualified; if the deviation value is outside the qualified range, it indicates that the product is unqualified.

[0061] As a further embodiment, it also includes a sampling task module 30 and a sampling information acquisition module 40; the sampling task module 30 is used to generate a sampling task; the sampling information acquisition module 40 is used to obtain the comprehensive basic information of the product according to the sampling task to obtain the sampling information.

[0062] Among them, the sampling task module 30 is used to generate a sampling task after the machine tool completes the production task of the day, and the sampling information acquisition module 40 is used to obtain the comprehensive basic information of the product to obtain the sampling information after the system generates the sampling task, and then the system confirms the sampling result based on the sampling information.

[0063] For example, when a machine tool completes the production of the day's production task, it is set as the target machine tool, and the products produced by the target machine tool are confirmed. Then, a product is randomly selected from the products produced by the target machine tool and set as the sampling product. The products selected by a target machine tool can be multiple or one, which can be set according to the actual situation.

[0064] After confirming the sampled product, obtain the comprehensive basic information of the sampled product to obtain the sampled information. The comprehensive basic information can also include basic information of production materials, basic information of process requirements, key quality control information and mold abnormal status information. The basic information of production materials, basic information of process requirements, key quality control information and mold abnormal status information can be written into the system by the staff, or obtained through sensors, which can be determined by the actual production environment. After obtaining the sampled information, confirm whether the sampled product is qualified according to the sampled information. If qualified, the qualified data is reported. If unqualified, the data is reported to the system. The system adjusts the production process of the product, that is, adjusts the parameters of the machine tool. When the product is re-produced, the product is tested again. If qualified, the data is reported. If still unqualified, the production process continues to be adjusted until the product is qualified.

[0065] The product inspection method and inspection system disclosed in the present invention can automatically confirm whether the product has completed the first inspection after the product is produced. If the first inspection has not been completed, the first inspection of the product can be automatically performed without the participation of staff, thereby improving the efficiency of product inspection and avoiding omissions.

[0066] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
