The position of the IC can be identified according to the IC material number. Each IC lot number has its corresponding IC inventory quantity. As shown in fig. 3, the product-in-process list includes six kinds of production information, i.e., a product type, a product quantity, a process type number, a process type name, a production state, and a product material number, and each kind of production information has corresponding original data below it, wherein the product type corresponds to the product material number one by one. The inventory forms and work-in-process forms are the basic forms for the automatic processing of subsequent COF production information. In this embodiment, a cx _ oracle method in a Python oracle library may be used in conjunction with a database statement to obtain data in an inventory form and a work-in-process form.
S2: dividing the process category number into six station categories according to the process category name, and dividing the finished product model, the process category number, the production state and the finished product number into six station category information forms according to the station categories; the finished product models contained in each station information form are the same.
In this example, the COF production process mainly comprises six stations: inner lead bonding ILB, gluing POT, testing FT, automatic visual inspection AVI, dot amount VC and packaging PK. A site may include a plurality of process category names, one process category name corresponding to a process category number. For example, the inner lead bonding ILB station includes process class numbers E010(ILB) and E011(ILBQC), respectively, E010(ILB) indicating inner lead bonding and E011(ILBQC) indicating inner lead bonding quality inspection.

The automatic visual inspection AVI station comprises process type numbers E080(COF-VI), E090(COF-AVI) and E095(TP), wherein E080(COF-VI) represents visual inspection, E090(COF-AVI) represents automatic detection, and E095(TP) represents patch. The dot-dose VC station includes the process type numbers E100(COF-VC) and E101(COF-VQC), wherein E100(COF-VC) represents the counting amount, and E101(COF-VQC) represents the quality inspection of the amount. The packaging PK station comprises E110(COF-PK1), E111(COF-PQC), E120(COF-PK2) and E121(COF-FQC), wherein the E110(COF-PK1) represents a packaging process I, the E111(COF-PQC) represents a packaging process I quality inspection, the E120(COF-PK2) represents a packaging process II, and the E121(COF-FQC) represents a packaging process II quality inspection.
With continued reference to fig. 3, the work-in-process list includes a plurality of process category numbers, each process number has a corresponding process category name, for example, the process category number E080 corresponds to the process category name COF-VI belonging to the automatic visual inspection AVI station, so that the process category numbers can be sorted into six corresponding station categories by the process category names to form six station category information lists. Each station information form contains five kinds of production information, namely station, finished product model, process type number, production state and finished product quantity. And, each process category number comprises three production states of queue, running and detaining in manufacturing, and the number of different product models is listed under each production state. In this embodiment, a station-specific information form may be established by using a pandas library, an openpyxl library, a matplotlib library, and the like in Python, and in this process, processing of null values and useless data may be determined by combining with for-loop, and then the null values and the useless data are cleared and converted by using a queue principle, and finally valuable and correct data is output to the station-specific information form. FIG. 4 illustrates an ILB stop-level information form, for example, a finished product model "test AST90016A-F311B version" 40 in number in queue at number E010 (ILB); the finished model numbers "AST 18817D (U), 43" UD "are 27016 in number in queue at number E010(ILB), 2690 in number in manufacture, etc., and the right-most side of the ILB site information form also counts the finished product number for each finished model. Through the ILB station type information form, the current finished product types can be known at a glance, and the number of the finished product types in different process type numbers is large, so that a worker can conveniently master related production information in time, and a next production plan can be arranged in advance.

As shown in fig. 10, the finished product model-IC model correspondence table includes an IC material number, an IC model, a finished product material number, and a finished product model, and is also a basic form, and since the IC model and the finished product model cannot be corresponded only by the stock form and the work-in-process form, the finished product model-IC model correspondence table needs to be used. The data in the finished product model-IC model corresponding table can be automatically acquired from a self-used database of an enterprise by compiling a script in Python language. The data in the enterprise automatic database is recorded and filled by workers, and comprises various production-related data such as an IC material number, an IC model number, a finished product material number, a finished product model number and the like. The corresponding relation between the IC material number and the finished product material number can be known from the finished product model-IC model corresponding table, one IC material number can correspond to one IC model, and one finished product material number can correspond to one finished product model, so that the IC model and the finished product model can be corresponding. Each station type information form comprises a plurality of finished product types, and the IC types corresponding to the finished product types can be obtained by searching in a finished product type-IC type corresponding table according to the finished product types. And then integrating the searched IC model with six station information forms to obtain a manufactured information Summary (SUM). As shown in fig. 11, the in-process information summary SUM includes a finished product number, a finished product model, an IC model, a number of finished products of six stations, and a total number. The information of the types of finished products currently produced, the types of used ICs, the quantity of finished products in each station, the total quantity of the types of the finished products and the like can be intuitively known from the SUM in the information summary chart, and workers can know the production condition of the whole production link from the chart, so that the production plan of the next step can be reasonably arranged, the yield can be controlled, and the working efficiency can be improved.
