Description

TECHNICAL FIELD

[0001] The present application relates to the field of 3D printing preparation of ceramic materials, and in particular to the field of a high-throughput production control method for 3D printing preparation of ceramic materials. BACKGROUND

[0002] Traditional ceramic forming technology has limitations such as long processing time, complex process flow, high cost, and inability to form complex products, which restrict the development of advanced ceramic industry. 3D printing technology uses a gradual accumulation method to manufacture solid parts, which has the advantages of not increasing the cost of manufacturing complex products, not requiring a mold, and being able to flexibly prepare highly complex and accurate structures, compared to traditional subtractive and equal material manufacturing methods, and thus has great potential in modern manufacturing.

[0003] 3D printing of ceramic materials includes processes such as preparation of ceramic slurry, 3D printing forming, and sintering; the performance indicators of the ceramic slurry preparation have a greater impact on the quality of the ceramic body prepared by 3D printing; therefore, the pass rate of large-scale 3D printing production of ceramic materials is low, and planning is difficult to form.

[0004] Therefore, how to invent a production control method for 3D printing preparation of ceramic materials to improve the pass rate of large-scale 3D printing production of ceramic materials has become a problem to be solved in the field. SUMMARY

[0005] The present application aims to provide a high-throughput production control method for 3D printing preparation of ceramic materials, which realizes the improvement of the pass rate of large-scale 3D printing production of ceramic materials.

[0006] The present application provides a high-throughput control method for ceramic powder production, which comprises the following steps:

[0007] A first database is constructed, which includes ceramic product category information, ceramic slurry raw material standard information data corresponding to different categories of ceramic products, and ceramic slurry raw material grade range data corresponding to different categories of ceramic products;

[0008] A raw material information grading method for different categories of ceramics is preset, and real-time raw material information data obtained during production is classified according to the different categories of ceramic slurry raw material grade range data to obtain different categories of real-time raw material quality grades;

[0009] A second database is constructed, which includes ceramic slurry preparation processes corresponding to different grades of real-time raw materials of different categories, and ceramic slurry grade range data corresponding to different categories of ceramic products;

[0010] The preset ceramic slurry grading method of different kinds of ceramics classifies real-time ceramic slurry information data obtained during production according to different kinds of ceramic slurry grade range data, and obtains different kinds of real-time ceramic slurry quality grades.

[0011] A third database is constructed, and the third database includes 3D printing forming processes corresponding to different kinds of different grade real-time ceramic slurries, and ceramic body grade range data corresponding to different kinds of ceramic products.

[0012] The preset ceramic body grading method of different kinds of ceramics classifies real-time ceramic body information data obtained during production according to ceramic body grade range data corresponding to different kinds of ceramic products, and obtains different kinds of real-time ceramic body quality grades.

[0013] A fourth database is constructed, and the fourth database includes sintering processes corresponding to different kinds of different grade real-time ceramic bodies, and ceramic product grade range data of different kinds.

[0014] The preset ceramic product classification method of different kinds classifies real-time ceramic product information data obtained during production according to ceramic product grade range data, and obtains different kinds of real-time ceramic product quality grades.

[0015] The beneficial effects of the present application relative to the prior art are that the first database is preset to store the names, technical features, quantity performance requirements of ceramic slurry raw materials required by different kinds of ceramic materials, and simultaneously store the qualified standard range, unqualified index range and adjustable index range of ceramic slurry raw materials corresponding to different kinds of ceramic products, so that when a production command including the kind of ceramic material is received, the required ceramic slurry raw materials can be automatically guided to be measured.

[0016] The preset raw material information grading method of different kinds of ceramics classifies the actual situation of the ceramic slurry raw materials measured during production, and confirms whether the obtained raw materials are qualified, unqualified or adjustable; the adjustable category does not meet the ceramic slurry raw material standard, but the ceramic slurry production process can be adjusted subsequently to achieve qualified ceramic slurry.

[0017] The second database is used to store the processing methods of different types and different levels of ceramic slurry raw materials, to stop processing of unqualified ceramic slurry raw materials, to avoid waste and improve the qualified rate; the ceramic slurry raw materials that do not meet the standard range of ceramic slurry raw materials but can be adjusted for use are adjusted to obtain qualified ceramic slurry quality by adjusting the ceramic slurry preparation method, thereby improving the qualified rate of ceramic materials; and the qualified standard range, unqualified index range and adjustable index range of the ceramic slurry corresponding to different types of ceramic products are stored.

[0018] The preset ceramic slurry grading method of different types of ceramics is used to classify the actual performance of the produced ceramic slurry, to confirm whether the prepared ceramic slurry is qualified, unqualified or adjustable; the adjustable category does not meet the ceramic slurry standard but can be adjusted in the subsequent ceramic body production process to achieve qualified ceramic body;

[0019] The third database is used to store the processing methods of different types and different levels of ceramic slurry, to stop processing of unqualified ceramic slurry, to avoid waste and improve the qualified rate; the ceramic slurry that does not meet the standard range of ceramic slurry but can be adjusted for use is adjusted to obtain qualified ceramic body quality by adjusting the ceramic body preparation method, thereby improving the qualified rate of ceramic body; and the qualified standard range, unqualified index range and adjustable index range of the ceramic body corresponding to different types of ceramic products are stored.

[0020] The preset ceramic body grading method of different types of ceramics is used to classify the actual performance of the produced ceramic body, to confirm whether the prepared ceramic body is qualified, unqualified or adjustable; the adjustable category does not meet the ceramic body standard but can be adjusted in the subsequent ceramic body sintering production process to achieve qualified ceramic;

[0021] The fourth database is used to store the processing methods of different types and different levels of ceramic body, to stop processing of unqualified ceramic body, to avoid waste and improve the qualified rate; the ceramic body that does not meet the standard range of ceramic body but can be adjusted for use is adjusted to obtain qualified ceramic product quality by adjusting the sintering process, thereby improving the qualified rate of ceramic product; and the qualified standard range and unqualified index range of different types of ceramic products are stored.

[0022] Therefore, through the high-throughput production control method, the raw materials, ceramic slurry and ceramic body in the process of 3D printing preparation of ceramic materials are classified in real time, and at least three categories are formed. The unqualified semi-finished products of each process are stopped from being used, and the semi-finished products of the next process that do not meet the standard range but can be adjusted to qualified semi-finished products of the next process by adjusting the production process of the next process are used as a level. The semi-finished products of this level are used in the corresponding production process of the next process, so that the qualified semi-finished products of the next process are obtained.
