Description

Technical Field

[0001] This invention belongs to the field of high-temperature production line technology, and in particular relates to a method for improving the intelligence of blade production lines. Background Technology

[0002] A steam turbine is a rotary steam power plant. High-temperature, high-pressure steam passes through a fixed nozzle, becomes an accelerated airflow, and is then sprayed onto the blades, causing the rotor, which is equipped with rows of blades, to rotate and perform work. It converts the thermal energy of steam into external combustion rotary mechanical energy. It is a major piece of equipment in modern thermal power plants, so the production of blades plays a decisive role in the function of steam turbines.

[0003] The current production process for blades is as follows: high-temperature degreasing - air cooling - sandblasting - primer spraying - low-temperature drying - high-temperature curing - air cooling - shot peening - high-temperature finishing - air cooling - preheating - topcoat spraying - low-temperature drying - high-temperature curing - air cooling - testing. Currently, most of this production process involves manual handling and manual production, which presents numerous problems such as high labor intensity, harsh working environments, untraceable product information, and unstable quality.

[0004] Of course, the transfer can be carried out using a control system in conjunction with a transport vehicle (AGV), and production can be carried out using robots. However, the blade tooling plates are divided into 11 levels, and the specifications, models and processing technology of each level are different. How to realize the connection of each production link, the selection of blade error prevention and operation procedures remains a problem. Summary of the Invention

[0005] The purpose of this invention is to provide a method for improving the intelligence of blade production lines, which can schedule AGVs according to a specified process, connect various production links, realize work procedure selection and error prevention functions, improve the level of manufacturing intelligence and digitalization, and reduce the labor input cost of production lines.

[0006] To achieve the above objectives, the technical solution of the present invention is: a method for improving the intelligence of a blade production line, comprising:

[0007] At the manual sorting station, blades are fixed to blade fixtures, and a barcode reader with a unique QR code is installed at the bottom of the fixture according to the blade grade. The QR code is decoded to obtain a string, the first two digits of which represent the blade grade. The manual sorting station is equipped with a transfer and transportation unit to transport the blade fixtures, and AGVs can connect to the fixtures at the end of the transport. The bottom of the transfer and transportation unit is equipped with a barcode reader, which reads the barcode on the blade fixture and transmits the reading information to the control system. The control system matches the corresponding process flow for the blade based on the reading information and dispatches the corresponding AGV to connect and transport the blade to the next workstation.

[0008] At the processing station, the AGV connects to the feeding area of ​​the processing workbench, and the blade tooling plate is transferred to the processing feeding transport section of the processing workbench. Both the bottom of the feeding transport section and the bottom of the discharging transport section are equipped with barcode readers. The barcode reader at the feeding transport section reads the barcode on the bottom of the blade tooling plate and transmits the information to the control system. The control system decodes the barcode and identifies the blade grade. The control system then sends the blade grade information to the processing robot, which determines the subroutine to be invoked. After processing, the discharging transport section transports the blade tooling plate. The barcode reader at the discharging transport section reads the barcode on the bottom of the blade tooling plate and transmits the information to the control system. The control system decodes the barcode and converts it into a data format containing station discharge port information. The control system then calls the AGV to connect and transport the blade tooling plate to the next station.

[0009] The inspection stations are divided into level 1-6 and level 7-11 inspection stations. The control system determines the blade level based on the code information read by the code reader at the end of the conveyor of the processing output transportation unit of the previous processing station, and calls an AGV to connect and transport the blade tooling plate to the inspection feed transportation unit of the corresponding inspection station. The inspection feed transportation unit is equipped with a code reader and transmits the code information to the control system. The control system decodes and converts the data, changing the decoding result from a string to a string + A format and sending it to the inspection robot. The inspection feed transportation unit transfers the blade tooling plate to the inspection table, and the inspection robot inspects the A side of the blade. The inspection robot's inspection program follows the decoding information sent by the control system. The system calls upon the information; after the A-side inspection is completed, the inspection robot returns to its original position; the inspection platform rotates 180 degrees until the B-side of the blade faces the inspection robot, and the inspection robot inspects the B-side of the blade; after the B-side inspection is completed, the inspection robot sends the inspection data of the blade to the control system and returns to its original position; the inspection platform rotates 180 degrees back to its original position, and the inspection platform transfers the blade tooling plate to the inspection and unloading transportation department, which transports the blade tooling plate. The barcode reader at the bottom of the inspection and unloading transportation department reads the barcode on the bottom of the blade tooling plate and transmits the barcode information to the control system. The control system decodes and converts the data into a data format with the station's discharge port information. The control system then calls upon the AGV trolley to connect and transport the blade tooling plate to the next station.

[0010] Furthermore, the QR code is a DataMatrix QR code.

[0011] Furthermore, the code reader includes a perforated code plate and a base plate, both of which are stainless steel plates; the base plate is located above the perforated code plate; the perforated code plate is coated with a first color of high-temperature paint, and the base plate is coated with a second color of high-temperature paint.

[0012] Furthermore, each of the barcode readers is equipped with a photoelectric sensor switch, which is used to sense the blade tooling plate. When the photoelectric sensor switch senses the blade tooling plate, it will activate the barcode reader to read the barcode.

[0013] Furthermore, the control system includes a result comparison system. The QR code, after decoding, yields a 4-digit string. The result comparison system compares the string length. If the collected string is a 6-digit "NOREAD", it indicates that the QR code was not successfully recognized. The control system issues a warning and controls the corresponding transportation department to stop conveying the blade tooling plate. If the collected string is a 4-digit string, it indicates that the QR code was successfully recognized, and the corresponding transportation department releases the blade tooling plate.

[0014] Furthermore, the transfer and transportation unit, the processing feed and transportation unit, the processing discharge and transportation unit, the inspection feed and transportation unit, the inspection discharge and transportation unit, and the inspection platform are all equipped with blocking structures. Each blocking structure includes a linear drive, a blocking block, and a fixing block. The blocking drive is connected to the control system. The linear drive is fixed to each transportation unit or inspection platform. The fixing block is fixed to the linear drive. The blocking block is rotatably connected to the fixing block. The driving end of the linear drive is located below one side of the blocking block, and the other side of the blocking block is used to block the blade tooling plate. A groove is provided below the blocking block, and the driving end of the linear drive is slidably connected in the groove.

[0015] Furthermore, the testing platform is provided with a testing and transport section, which is used to receive the blade tooling plate on the testing and feeding transport section and to transfer the blade tooling plate to the testing and discharging transport section; a rotating section is provided below the testing platform, which is used to drive the testing platform to rotate; a gap is left between the testing platform and the testing and feeding transport section and the testing and discharging transport section to allow the testing platform to rotate.

[0016] Furthermore, the manual sorting table is equipped with a lifting device; the lifting device includes a lifting drive, a lifting frame, and a lifting rod; the lifting drive is used to drive the lifting rod to move vertically, the top of the lifting rod is fixed to the lifting frame, and the lifting frame is used to support the blade tooling plate; the lifting frame can be lowered to a height lower than that of the transfer and transportation section.

[0017] Furthermore, each of the detection feeding transport section, detection discharging transport section, processing feeding transport section, and processing discharging transport section can simultaneously transport up to n sets of blade tooling plates, and each transport section is equipped with n sets of blocking structures; the blocking structures are equipped with blade tooling sensors connected to the control system. In the transport direction, when there is no blade tooling sensor at the m-th blocking structure, the (m-1)-th blocking structure releases the blade tooling plate; 2≤m≤n.

[0018] Furthermore, a U-shaped structure is formed between the detection feeding transport section, the detection transport section, and the detection discharging transport section; a transport receiving section is provided at both the end of the detection feeding transport section and the beginning of the detection discharging transport section; the transport receiving section includes a transport structure and a lifting structure; the transport height of the detection feeding transport section and the detection discharging transport section is lower than that of the detection transport section; the lifting structure is used to drive the vertical movement of the transport structure, and the transport structure can connect with the detection transport section and can be located below the detection feeding transport section and the detection discharging transport section; the transport direction of the transport structure is the same as the transport direction of the detection transport section.

[0019] The beneficial effects of this technical solution are as follows:

[0020] ① To differentiate between blades of different grades, a unique code reader is attached to the bottom of each blade tooling plate. By reading and identifying the code on the code reader at the bottom of the blade tooling plate, the matching processing program is called, and the code reading data is uploaded to the control system. The control system schedules the AGV trolleys according to the specified process, connects each production link, and realizes blade traceability, operation program selection, and error prevention functions. This can improve the level of manufacturing intelligence and digitalization, reduce the labor input cost of the production line, and improve the safety of operation and the uniformity of product quality.

[0021] ② Due to the use of stainless steel, the color of the code reader will change after being baked at high temperature. In order to fix the color of the code reading area, two different colors of high-temperature paint are used to protect and color the surface of the code plate and the base plate. When the code reader and the blade tooling plate are put into the 400-degree high-temperature furnace together, the second color of high-temperature paint on the base plate will become the third color, and the first color of high-temperature paint on the code plate will become the fourth color. After a stable color difference is formed between the hole and the base plate, it is easier to read the code.

[0022] ③ Traditional barcode readers can only transmit the recognition results. Based on the actual situation on site, we need to know whether the barcode reading was successful. Therefore, a result comparison system is set up. If the conditions are met, the blocking structure can be driven to allow the tooling plate to pass through and flow into the next station.

[0023] ④ The technical solution incorporates a barrier structure to ensure the orderly transport of each part.

[0024] ⑤ In this technical solution, the detection feeding conveyor section, the detection conveyor section, and the detection discharging conveyor section are designed with a U-shaped structure, which reduces the conveying length and makes the structure more compact. The conveying receiving section allows for connection between the end of the detection feeding conveyor section and the beginning of the detection discharging conveyor section.

[0025] ⑥ A lifting device is provided in this technical solution to provide space for fixing the blade tooling plate and the blade. Attached Figure Description

[0030] The following detailed description illustrates the specific implementation method:

[0031] The reference numerals in the accompanying drawings include: blade tooling plate 1, barcode reader 2, manual sorting table 3, transfer and transportation section 4, barcode reader 5, lifting frame 6, lifting rod 7, blocking structure 8, inspection feeding and transportation section 9, inspection table 10, inspection discharging and transportation section 11, transportation receiving section 12, blade 13, inspection and transportation section 14, linear drive component 15, fixing block 16, blocking block 17, and roller 18.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] A method to improve the intelligence of blade production lines involves improvements in the following aspects:

[0034] like Figure 1 , 2As shown, blade 13 is fixed to blade fixture plate 1 at manual sorting station 3, and a barcode reader 2 with a unique QR code is installed at the bottom of blade fixture plate 1 according to the grade of blade 13. The QR code is a DataMatrix QR code, which is a matrix QR code. Its characteristics are large information storage capacity and strong resistance to contamination. The required 4-digit code is entered into ezCAD software. During the code generation process, DataMatrix is ​​optimized, which can automatically generate and export the QR code PDF file. The PDF file is converted into a GPJ image file using SCAN2CAD vector editing software. The GPJ image file is then exported as a DXF format file using conversion software. Finally, the perforation code is arranged using AutoCAD to obtain the final QR code. The code reader 2 includes a perforated code plate (160*110*2mm) and a base plate (160*110*1.5mm), both of which are made of stainless steel. The base plate is located above the perforated code plate. The perforated code plate is coated with a first-color high-temperature paint (specifically, gray high-temperature paint), and the base plate is coated with a second-color high-temperature paint (specifically, white high-temperature paint). The coating method is as follows: first, a layer of primer is sprayed, and after drying, the first high-temperature paint is sprayed, and after drying, the second high-temperature paint is sprayed. When the code reader 2 and the blade tooling plate 1 enter the 400-degree high-temperature furnace together, the white high-temperature paint on the base plate will turn brown. After a stable color difference is formed between the perforated code plate and the base plate, it is easier to read the code. The manual sorting table 3 is equipped with a lifting device, which includes a lifting drive, a lifting frame 6, and a lifting rod 7. The lifting drive (specifically a lifting cylinder) drives the lifting rod 7 to move vertically. The top of the lifting rod 7 is fixed to the lifting frame 6, which supports the blade tooling plate 1. The lifting frame 6 can descend to a height lower than the transfer and transportation section 4, allowing the blade tooling plate 1 to fall onto the transfer and transportation section 4. The QR code can be decoded to obtain a 4-digit string, the first two digits of which represent the grade of the blade 13. The manual sorting table 3 is equipped with a transfer and transportation section 4 to transport the blade tooling plate 1. AGV carts can connect at the end of the manual sorting table 3. The bottom of the transfer and transportation section 4 is equipped with a barcode reader 5, which reads the barcode on the barcode reading plate 2 at the bottom of the blade tooling plate 1 and transmits the reading information to the control system. The control system matches the process flow corresponding to the blade 13 based on the reading information and dispatches the corresponding AGV cart to connect and transport it to the next workstation.

[0035] At the processing station, the AGV connects to the feeding area of ​​the processing workbench, and the blade tooling plate 1 is transferred to the processing feeding transport section of the processing workbench. Both the bottom of the feeding transport section and the bottom of the discharging transport section are equipped with barcode readers 5 (or alternatively, barcode readers 5 can be installed at the beginning of the transport). The barcode reader 5 at the feeding transport section reads the barcode on the barcode reading plate 2 at the bottom of the blade tooling plate 1 and transmits the reading information to the control system. The control system decodes the reading information and identifies the grade of the blade 13; the control system then sends the grade information of the blade 13 to... The processing robot determines the subroutine to be called. After processing, the processing and unloading transportation department transports the blade tooling plate 1. The code reader 5 at the end of the conveyor of the processing and unloading transportation department reads the code on the code reading plate 2 at the bottom of the blade tooling plate 1 and transmits the reading information to the control system. The control system decodes and converts it into a data format with station outlet information, specifically into a string + fixed number format. The string represents the value of the code reading plate 2, and the fixed number represents the fixed station outlet. The control system calls the AGV to connect and transport the blade tooling plate 1 to the next station.

[0036] The inspection stations are divided into inspection stations of levels 1-6 and inspection stations of levels 7-11. The control system determines the level of the blade 13 based on the code reading information read by the code reader 5 at the end of the conveying section of the processing output transportation department of the previous processing station, and calls the AGV trolley to connect and transport the blade tooling plate 1 to the inspection feeding transportation department 9 of the inspection workbench of the corresponding inspection station. Figure 3As shown, the conveying end of the inspection feeding and transporting unit 9 is equipped with a code reader 5, which transmits the code information to the control system. The control system decodes and converts the data, changing the decoding result from a string to a string + A format and sending it to the inspection robot. The inspection feeding and transporting unit 9 transfers the blade tooling plate 1 to the inspection table 10. The inspection robot inspects the A side of the blade 13 (e.g., roughness and thickness detection). The inspection robot's inspection program is invoked according to the decoding information sent by the control system. After the A side inspection is completed, the inspection robot returns to its original position. The inspection table 10 rotates 180 degrees until the B side of the blade 13 faces the inspection robot, and the inspection robot inspects the B side of the blade 13. After the B side inspection is completed, the inspection robot sends the inspection data of the blade 13 to the control system and returns to its original position. The inspection platform 10 rotates 180 degrees back to its original position, and then transfers the blade tooling plate 1 to the inspection and discharge transportation section 11. The inspection and discharge transportation section 11 transports the blade tooling plate 1. The barcode reader 5 at the end of the conveyor of the inspection and discharge transportation section 11 reads the barcode reading plate 2 at the bottom of the blade tooling plate 1 and transmits the reading information to the control system. The control system decodes and converts the data into a data format with station discharge port information. Specifically, it converts the data into a string + fixed number format. The string represents the value of the barcode reading plate 2, and the fixed number represents the fixed station discharge port. The control system calls the AGV trolley to connect and transport the blade tooling plate 1 to the next station.

[0037] Each of the barcode readers 5 is equipped with a photoelectric sensor switch. The photoelectric sensor switch is used to sense the blade tooling plate 1. When the photoelectric sensor switch senses the blade tooling plate 1, it will activate the barcode reader 5 to read the barcode.

[0038] The control system is equipped with a result comparison system. After the QR code is decoded, a 4-digit string can be obtained. The result comparison system is used to compare the length of the string. If the collected string is a 6-digit "NOREAD", it means that the QR code has not been successfully recognized. The control system issues a warning and controls the corresponding transportation department to stop conveying the blade tooling plate 1. If the collected string is a 4-digit string, it means that the QR code has been successfully recognized. The corresponding transportation department then releases the blade tooling plate 1.

[0039] The transfer and transportation department 4, the processing material inlet and outlet transportation department, the inspection material inlet and outlet transportation department 9, the inspection material outlet transportation department 11, and the inspection table 10 are all equipped with blocking structures 8, such as... Figure 4As shown, the blocking structure 8 includes a linear drive 15 (blocking cylinder), a blocking block 17, and a fixing block 16. The blocking drive is connected to the control system. The linear drive 15 is fixed on each transport section or inspection table 10. The fixing block 16 is fixed on the linear drive 15. The blocking block 17 is rotatably connected to the fixing block 16. The driving end of the linear drive 15 is located below one side of the blocking block 17, and the other side of the blocking block 17 is used to block the blade tooling plate 1. A groove is provided below the blocking block 17, and the driving end of the linear drive 15 is slidably connected in the groove. A roller 18 is provided on the blocking block 17, and the roller 18 is used to block the blade tooling plate 1. The material feeding and conveying section 9, the material discharging and conveying section 11, the processing material feeding and conveying section, and the processing material discharging and conveying section can each transport up to n sets of blade tooling plates 1 simultaneously. Each conveying section is equipped with n sets of blocking structures 8. The blocking structures 8 are equipped with blade tooling sensors (such as photoelectric switches or infrared sensors) connected to the control system. In the conveying direction, when there is no blade tooling sensor at the m-th blocking structure 8, the (m-1)-th blocking structure 8 releases the blade tooling plate 1; 2≤m≤n.

[0040] When the photoelectric sensor detects that material has arrived, the blade tooling plate 1 continues to be transported to the first set of blocking structures 8. If the blade tooling sensor at the second set of blocking structures 8 does not detect material and the first set of blocking structures 8 has material, the first set of blocking structures 8 is opened, and the blade tooling plate 1 is transported to the second set of blocking structures 8, and so on.

[0041] like Figure 3 As shown, the inspection table 10 is equipped with an inspection transport section 14, which is used to receive the blade tooling plate 1 on the inspection feed transport section 9 and to transfer the blade tooling plate 1 to the inspection discharge transport section 11. A rotating section (servo motor) is located below the inspection table 10, which drives the inspection table 10 to rotate. A gap is provided between the inspection table 10 and the inspection feed transport section 9 and the inspection discharge transport section 11 to allow the inspection table 10 to rotate. The inspection feed transport section 9, the inspection transport section 14, and the inspection discharge transport section 11 form a U-shaped structure. Both the end of the inspection feeding transport section 9 and the beginning of the inspection discharging transport section 11 are provided with transport receiving sections 12; the transport receiving section 12 includes a transport structure and a lifting structure; the transport height of the inspection feeding transport section 9 and the inspection discharging transport section 11 is lower than that of the inspection transport section 14; the lifting structure is used to drive the transport structure to move vertically, and the transport structure can connect with the inspection transport section 14 and can be located below the inspection feeding transport section 9 and the inspection discharging transport section 11; the transport direction of the transport structure is the same as that of the inspection transport section 14.

[0042] The transfer and transportation department 4, the processing material inlet and transportation department, the processing material outlet and transportation department 9, the inspection material inlet and transportation department 11, the inspection material outlet and transportation department 14, and the transportation structure adopt the use of transfer rollers, transfer rollers or a combination of both.
