Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of generator coil, in particular to a stator coil full life cycle identification method. BACKGROUND

[0002] As one of the core components of the generator, the quality of the stator coil is of great importance, and it affects the design, manufacture, installation, maintenance and maintenance of the unit. The full life cycle management of the stator coil of the unit is one of the problems that have been concerned by the whole industry in recent years. In order to realize the quality management, problem tracing and process control of the full life cycle of the stator coil, the coil number needs to be marked on each coil. Due to the complex manufacturing process of the stator coil, the shape of the product is not uniform before and after the product is manufactured, and there are different working conditions such as high temperature and polishing during the manufacturing process, so the product marking position and marking method are quite different.

[0003] The traditional scheme is that in the previous manufacturing winding process, the coil number is handwritten on the stator coil by using a marker pen at a visible position, or the coil number is manually engraved by using a steel stamping die. After the straight line is glued, the coil number is transferred to the middle side of the straight line by using a marker pen again. After the end is sealed and the head block is connected, the coil number is engraved on the short end of the head block by using a steel stamping die. During the manufacturing process, the code is identified and engraved manually, and the manufacturing process control is recorded manually.

[0004] If the data needs to be viewed in the traditional coding method, the paper record needs to be found by comparing the actual code, which has the problems of low identification efficiency, inaccurate marking, human identification error and the like. The coil manufacturing is a mixed-line manufacturing of multiple varieties, and the conventional coding cannot ensure the uniqueness of the data of a single coil. The conventional paper record also has the problems of difficult data query, difficult storage and transportation of paper, and the manual record cannot meet the accuracy of the manufacturing data in the digital workshop. In order to promote the digitization of the key core components of the generator, the existing coding method and marking scheme cannot meet the requirements of unique marking and rapid information transmission.

[0031] The features and performances of the present application will be further described in detail below with reference to the embodiments.

[0032] Embodiment one

[0033] As shown in Figure 1 , the present application is a stator coil full life cycle identification method, comprising the following steps:

[0034] According to the coding rule, the identification of the stator coil is automatically generated and printed using a self-adhesive label ribbon;

[0035] The stator coil is cut, and the self-adhesive label ribbon is pasted on one end of the cut strand;

[0036] Through the production management system, the stator coil identification information is uniformly etched on the water and electricity joint box by laser etching;

[0037] When the end of the stator coil is solidified, the end of the strand is spaded, and the excess part of the stator coil end and the label ribbon are removed;

[0038] The stator coil is sealed and welded, and the etched identification of the water and electricity joint box is welded on one end of the corresponding stator coil;

[0039] After the identification on the water and electricity joint box etched by laser is sanded and polished by using a flat sanding tool, the stator coil can be manufactured subsequently.

[0040] In this embodiment, after the manufacturing task is issued by the MOM (Production Management System), a coding identifier is automatically generated according to the coding rules and printed using self-adhesive label tape. After the stator coil is cut, the label tape is pasted onto the end of one strand, thus identifying the product from the pre-manufacturing stage. Before the stator coil is sealed, the coding identifier is uniformly etched onto the water and electricity connector box using laser etching, with an etching depth of 1mm. After the stator coil is braided and its ends are fixed, the braided stator coil is then scraped to remove the excess part at the end of the stator coil. The label tape falls off along with the scraped stator coil and is brazed to both ends of the stator coil through the medium-frequency induction water and electricity connector box. After welding, due to the heat generated during the welding process, the etched depth of the stator coil's identifier turns black. Subsequently, it is polished using a flat sanding tool before proceeding with subsequent manufacturing.

[0041] In the stator coil production process of this invention, the water and electricity connector box needs to be laser-etched in advance using a high-intensity / low signal-to-noise ratio single-source laser etching method. When the water and electricity connector box is sealed to the stator coil end, it is oxidized by heat, and the internal markings turn deep black. Polishing with a flat sanding tool enhances the contrast of the markings and effectively suppresses metal mirror reflection when scanning copper (non-ferrous metal), facilitating rapid identification using barcode scanners or PDAs, thus forming a permanent and unique identifier for the stator coil. The production process of this invention uses color-coded labels before the laser-etched markings are welded onto the water and electricity connector box. The marking process is tightly integrated, highly reliable, provides permanent markings, and is easy to operate, achieving interconnection and interoperability of information throughout the stator coil's entire lifecycle. After welding, laser etching combined with polishing with a flat sanding tool results in a strong contrast between the etched content and the background color, high recognizability, and a long shelf life.

[0042] Preferably, the encoding rules include stator coil number and stator coil sequence number, wherein the stator coil number and stator coil sequence number are encoded using a combination of multi-digit numbers and character codes.

[0043] Preferably, the stator coil number includes the unit part number, drawing item number, and coil number, and is identified using a visual string method.

[0044] Preferably, the stator coil serial number includes a feature code, order date, and serial number, which are encoded using DM code and then marked next to the stator coil number.

[0045] like Figure 2 As shown, in this invention, the stator coil identifier is split into a stator coil number and a stator coil serial number. Both the stator coil number and the stator coil serial number are composed of a multi-digit / character mixed encoding, providing strong confidentiality. The encoding rules are as follows: Figure 2As shown, the stator coil number corresponds to the stator coil "name", and the stator coil serial number corresponds to the stator coil "ID card number", wherein the stator coil number is directly marked on the stator coil in the form of a visible string, and the stator coil serial number is marked below the stator coil number after being encoded by a fast-identifiable DM code.

[0046] The coding rule of the present application uses the combination of the stator coil number and the stator coil serial number, and jointly uses digital / character code hybrid coding to form the permanent identification of the stator coil, thereby realizing the identification uniqueness principle in the mixed-line manufacturing process of the stator coil with multiple capacities, multiple types and multiple varieties, and achieving the unique identification which can be recognized by humans and quickly input through information means.

[0047] Preferably, in the production process of the stator coil, the stator coil production process information is collected by a digital gauge on the quality data of the stator coil, and uploaded to the database, and the identification of the stator coil is identified by a code scanning gun or a PDA, and the identification information is associated with the stator coil production process information.

[0048] Preferably, after the stator coil is put into use, the power station owner information thereof is also uploaded to the database, and the power station owner information of the stator coil is associated with the identification information of the stator coil.

[0049] Preferably, the stator coil production process information includes production information, process information, material information and / or equipment information; and the power station owner information includes the off-line installation and operation and maintenance information of the stator coil.

[0050] As shown in the figure, Figure 3 In the manufacturing process of the stator coil, the operator can quickly obtain the basic information of the coil through the stator coil number, and in the manufacturing process of the stator coil, the identification of the stator coil is identified by a code scanning gun or a PDA, and the quality data of the stator coil is collected by a digital gauge, and uploaded to the database, and the stator coil manufacturing (production) process information is associated with the identification of the stator coil. When the stator coil is subsequently off-line installed and operated and maintained, the information of the off-line installation and operation and maintenance is also transmitted to the database, and is associated with the identification of the stator coil, and the identification of the stator coil is associated with the whole life cycle information of the stator coil, thereby facilitating the quality query and traceability in the later period.

[0051] The first digital workshop manufacturing and management process transparency of the generator stator coil of the intelligent manufacturing digital workshop construction of large-scale clean and efficient power generation equipment in the industry is realized, the quality information is digitized, the effective flow of data is ensured, and the uniqueness of the data is ensured.

[0052] The application avoids the possibility of manual transcription error after original manual reading by checking in the DM code, and realizes the fast input of the stator coil identification information. The original product identification implementation mode needs multiple high temperature + polishing treatment + manual transcription defects, and realizes integrated continuous etching + automatic image recognition, and the system automatically identifies errors / repetition / missing code and the like identification.

[0053] The application provides a tool for the MES (manufacturing execution system), and helps the stator coil manufacturing plan scheduling, manufacturing task query, quality detection and control, statistical analysis and the like, improves the manufacturing site dark box operation, and improves the stator coil quality control.

[0054] The above is only the preferred embodiment of the application, but the protection scope of the application is not limited to this, any person skilled in the art can think of changes or replacements within the technical range disclosed by the application without creative labor, which should be covered in the protection scope of the application. Therefore, the protection scope of the application should be limited by the protection scope defined in the claims.
