Description

Technical Field

[0001] The present invention relates to the field of casting technology, and in particular to a method, device and terminal for printing cast character marks based on three-dimensional (3D) printing. Background Art

[0002] In the current foundry industry, castings are typically required to have clear and durable identification on their products, including the manufacturer's name or trademark, implementation standard number, cast iron material, specification model, and traceability number (production time and batch number). However, existing casting identification technology in the lost foam casting industry typically utilizes polycarbonate (PC) plastic sheets vacuum-formed through aluminum molds. The formed labels are then manually cut and reorganized to create the desired identification code or number, which is then affixed to the corresponding location on the casting product model.

[0003] It has the following disadvantages: 1. Since PC plastic plates are used for vacuum forming through letter plate molds, the quality of the forming process is difficult to guarantee. Usually, there will be phenomena such as poor forming, cracking and damage of the logo, and skewed fonts, which will cause rework and reduce production efficiency. 2. For the casting logo formed by vacuum forming, the operator can only form a single or individual logo (letter or number) per batch, and then manually cut and reorganize the layout to obtain the final required logo. Therefore, the logo needs to be manually checked and confirmed item by item. The amount of information in the operation is large, the production efficiency is low, and it is very easy to make mistakes due to frequent human participation. Summary of the Invention

[0047] In the following description, specific details such as particular system structures and techniques are provided for purposes of illustration, not limitation, to facilitate a thorough understanding of the embodiments of the present invention. However, it will be apparent to those skilled in the art that the present invention may be practiced in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0048] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below with reference to the accompanying drawings.

[0049] Figure 1 The implementation flow chart of the method for printing a cast mark based on 3D printing provided in an embodiment of the present invention is detailed as follows:

[0050] Step 101: obtain the numbers, letters and symbols to be modeled, model the numbers, letters and symbols, and send the modeled models to a database for storage.

[0051] Optionally, before performing step 101 , the MES needs to be connected to the 3D printing device. The MES and the 3D printing device can be connected via hardware or wirelessly via Bluetooth, a computer program, or Wireless Fidelity (WiFi).

[0052] After connecting MES with 3D printing equipment, the model in the database can be directly called according to the order information, and finally batch printing can be performed using 3D printing equipment. This not only reduces the error rate, but also improves work efficiency and reduces labor costs.

[0053] The numbers to be modeled are mainly 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9, the letters to be modeled are mainly D, P, N, A, B, C, G, T, Q, K and L, and the symbols to be modeled are mainly "X", " / ", "°", "=", "-" and ".".

[0054] The present invention only provides some of the numbers, letters and symbols to be modeled. In practical applications, the numbers, letters and symbols to be modeled can be increased or modified.

[0055] In one possible implementation, monomer modeling is performed on the data in the numbers, letters, and symbols to obtain a monomer modeling model, and the modeled model is sent to a monomer model database of a database for storage;

[0056] Optionally, monomer modeling is to independently model the data in numbers, letters and symbols to obtain individual number, letter and symbol models.

[0057] Alternatively, the data in the numbers, letters and symbols are combined and modeled according to the preset identification information to obtain a combined modeling model, and the modeled combined modeling model is sent to the combined model database of the database for storage.

[0058] Combination modeling is to select data from numbers, letters and symbols according to preset identification information, and then combine and sort the selected data to form a combination modeling model with the same composition order as the preset identification information.

[0059] By setting the combined modeling model corresponding to the preset identification information, the combined modeling model can be directly selected in the subsequent printing process, avoiding the problem of wasting time and manpower caused by repeated combination.

[0060] Optionally, both the single-body modeling model and the combined modeling model are provided with different font sizes. In application, the font size can be selected according to actual needs to meet the needs of different casting models.

[0061] Identification information includes identification number identification, specification model identification, and material and wall thickness grade identification. The preset identification information is the identification information of commonly used national standards, such as the identification number identification of a national standard shown in Figure 2 (a), the specification model identification of an iron 11.25° elbow shown in Figure 2 (b), and the material and wall thickness grade identification of a national standard shown in Figure 2 (c). Among them, DN1000 in Figure 2 (b) indicates the product, and 11.25° indicates the elbow angle; QT420-5 in Figure 2 (c) indicates that the product material is ductile iron, 420 indicates tensile strength, 5 indicates product elongation, and K12 indicates product wall thickness grade.

[0062] Step 102: Obtain order information in the manufacturing execution system, number each order in the manufacturing execution system, and use the number as a traceability number.

[0063] In one possible implementation, each order in the manufacturing execution system is numbered according to a pattern of date and serial number, and the date and serial number are combined in a preset sequence.

[0064] refer to Figure 3 As shown in the schematic diagram of the traceability number composition, it can be seen that the traceability number consists of a date and a serial number. The present invention is not limited to the order of the date and serial number. The composition order can be year, month, day and serial number. For example, 221215000, which means that the order year is 22, the month is December, the day is the 15th, and the serial number is 000. It can also be day, month, year and serial number, serial number, year, month and day, etc.

[0065] Optionally, the serial number is incremented by one from the first order. For example, the serial number of the first order is 000, and the serial number of the second order is 001. The serial number ranges from 000 to 999.

[0066] Numbering each order and obtaining a traceability number can not only ensure the one-to-one correspondence between the order and the casting model, but also facilitate the subsequent identification and delivery of the casting model, thereby improving production efficiency. The setting of the serial number can also clearly reflect the production volume.

[0067] Step 103: query the database for the target model corresponding to the order information and the traceability number, and print out the target model using a 3D printing device.

[0068] In one possible implementation, determining whether the identification information in the order information is preset identification information;

[0069] Optionally, the identification information in the order information may include identification number identification, specification model identification, material and wall thickness grade identification, and other identification information.

[0070] If the identification information in the order information is the preset identification information, searching the combination modeling model corresponding to the identification information in the combination model database, and printing the combination modeling model using a 3D printing device;

[0071] If the identification information in the order information is preset identification information that already exists in the combined model database, then the preset identification information is directly called and sent to the 3D device for printing without sorting and combining. For example, if the identification information in the order information is GB / T 13295, and GB / T 13295 is the preset identification information, then GB / T 13295 in the combined model data is directly sent to the 3D device for printing.

[0072] Obtain the traceability number, query the monomer modeling model corresponding to the traceability number in the monomer model database according to the traceability number, sort and combine all the queried monomer modeling models to obtain the traceability number modeling model, and use 3D printing equipment to print the traceability number modeling model.

[0073] Optional, because the traceability number includes the serial number, and the size of the serial number will change, the traceability number needs to call the monomer modeling model in the monomer model database for sorting and combination, and cannot directly call the combined modeling model.

[0074] Optionally, the traceability number call process is as follows: For example, if the traceability number is 220612001, then the numbers "2," "0," "1," and "6" in the individual model data are called based on 220612001. These numbers are sorted and combined to obtain a model with the same sequence as the traceability number. During the modeling process, a piece of data may be used multiple times.

[0075] In one possible implementation, if the identification information in the order information is not the preset identification information, a monomer modeling model corresponding to the identification information is searched in a monomer modeling database, all the searched monomer modeling models are sorted and combined to obtain a monomer modeling model corresponding to the order information, and the monomer modeling model corresponding to the order information is printed using a 3D printing device;

[0076] Obtain the traceability number, query the monomer modeling model corresponding to the traceability number in the monomer model database according to the traceability number, sort and combine all the queried monomer modeling models to obtain the traceability number modeling model, and use 3D printing equipment to print the traceability number modeling model.

[0077] Optionally, when determining whether the identification information in the order information is the preset identification information, there may be cases where the identification information in the order information is not the preset identification information. For example, if the identification information in this case is GB / T 13673, the numbers "1", "3", "6", and "7", the letters "G", "B", and "T", and the symbol " / " from the single model database need to be retrieved. Finally, the retrieved data is sorted and combined according to the identification information to obtain the modeling model corresponding to the identification information.

[0078] In one possible implementation, determining whether the identification information in the order information is preset identification information;

[0079] If the identification information in the order information is the preset identification information, query the combination modeling model corresponding to the identification information in the combination model database;

[0080] If the identification information in the order information is not the preset identification information, query the monomer modeling model corresponding to the identification information in the monomer modeling database, sort and combine all the queried monomer modeling models to obtain the monomer modeling model;

[0081] Obtain the traceability number, query the monomer modeling model corresponding to the traceability number in the monomer model database according to the traceability number, and sort and combine all the queried monomer modeling models to obtain the traceability number modeling model;

[0082] Combining the combined modeling model and the traceability number modeling model to obtain a target model; or combining the single modeling model and the traceability number modeling model to obtain a target model;

[0083] Send the target model to the 3D device for printing.

[0084] Optionally, the present invention provides three printing methods, namely, printing the combined modeling model and then printing the traceability number modeling model; printing the single modeling model and then printing the traceability number modeling model; obtaining one of the combined modeling model or the single modeling model, combining it with the traceability number modeling model, obtaining the target model and then printing.

[0085] The three printing methods are as follows: 1. Querying the combined modeling model corresponding to the identification information in the combined model database, and printing the combined modeling model corresponding to the identification information using a 3D printing device; Querying the single modeling model corresponding to the traceability number in the single model database, and sorting and combining all the queried single modeling models to obtain the traceability number modeling model, and printing the traceability number modeling model using a 3D printing device;

[0086] 2. Query the monomer modeling model corresponding to the identification information in the monomer model database, sort and combine all the queried monomer modeling models to obtain the monomer modeling model corresponding to the order information, use a 3D printing device to print the monomer modeling model corresponding to the identification information, query the monomer modeling model corresponding to the traceability number in the monomer model database, sort and combine all the queried monomer modeling models to obtain the traceability number modeling model, and use a 3D printing device to print the traceability number modeling model;

[0087] 3. Determine whether the identification information in the order information is the preset identification information;

[0088] If yes, query the combined model database for the combined model model corresponding to the identification information, query the monomer model model database for the monomer model model corresponding to the traceability number, and sort and combine all the queried monomer model models to obtain the traceability number model model;

[0089] If not, query the monomer modeling model corresponding to the identification information in the monomer model database, and sort and combine all the queried monomer modeling models to obtain the monomer modeling model corresponding to the order information, query the monomer modeling model corresponding to the traceability number in the monomer model database, and sort and combine all the queried monomer modeling models to obtain the traceability number modeling model;

[0090] Combining the combined modeling model and the traceability number modeling model to obtain a target model; or combining the single modeling model and the traceability number modeling model to obtain a target model;

[0091] Send the target model to the 3D device for printing.

[0092] In one possible implementation, after the target model is printed out using a 3D printing device, the target model can be pasted on a preset position of the casting model corresponding to the order to obtain a final casting model;

[0093] like Figure 4 The casting model and the corresponding target model pasting position diagram shown in FIG. can paste the target model at the preset position of the casting model. The present invention does not limit the pasting position. For example, for Figure 4 The casting model shown can be pasted on the outer wall of the target model, and can be pasted on both sides for aesthetics.

[0094] The final casting model is cast to obtain a casting product.

[0095] The pasted casting model is subjected to lost foam casting to obtain the final product.

[0096] The embodiment of the present invention provides a method for printing a cast mark based on 3D printing, which connects a manufacturing execution system with a 3D printing device, obtains numbers, letters and symbols to be modeled, models the numbers, letters and symbols, and sends the modeled models to a database for storage; obtains order information in the manufacturing execution system, numbers each order in the manufacturing execution system, and uses the number as a traceability number; queries the database for a target model corresponding to the order information and the traceability number, and prints the target model using a 3D printing device. By connecting an MES with a 3D printing device, the present invention solves the problem that in the traditional technology, PC plastic plates are vacuum-formed by using a plate mold, the quality of the vacuum forming is difficult to ensure, and the vacuum forming is usually poor, the mark is cracked and damaged, the font is skewed, etc., which causes rework and reduces production efficiency. It also solves the problem that the existing technology cannot connect the MES with the production process, and the operator can only vacuum-form a single or individual mark in each batch and then manually cut and reorganize it according to the order information to obtain the final cast mark, resulting in a large amount of work information, low production efficiency and high error proneness. Therefore, the present invention can obtain a cast logo with better molding, and in the logo production process, through the intelligent processing of MES and 3D equipment, the production and work efficiency is improved and the labor cost is reduced.

[0097] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

For ease of explanation, only the parts related to the embodiment of the present invention are shown, which are detailed as follows:
