Second Intelligent has assisted a leading manufacturer of new energy vehicles
to complete the capacity upgrade of its IGBT production line
IGBT (Insulated Gate Bipolar Transistor) is a kind of energy conversion and transmission of the core device, known as the industry power electronic device “CPU”, widely used in motor energy saving, rail transportation, smart grid, aerospace, home appliances, automotive electronics, new energy generation, new energy vehicles and other fields.
as the power electronics industry “CPU”, IGBT is internationally recognized as the most representative product of the electronic revolution. Multiple IGBT chips are integrated and packaged together to form an IGBT module, which has greater power and better heat dissipation capability, and plays an extremely important role in the field of new energy vehicles.
In order to meet the growing market demand , a leading new energy vehicle manufacturer ，will upgrade the production capacity of IGBT production line, and it is proposed to adopt the assembly line form of online production for gluing, framing, and baking processes. After the bidding in China, Shenzhen Second Intelligent Equipment Co., Ltd (“Second Intelligent”) successfully won the bidding for the project, and provided the whole line technical solutions such as IGBT laser marking, code scanning confirmation, automatic glue dispensing application, AOI inspection, framing, screwing, riveting, automatic baking and MES docking to realize the automation, intelligentization and integration of the production line. After completion, IGBT module production line capacity from the original 45S/PCS to 30S/PCS, will meet the brand of new energy vehicles, photovoltaic on the demand for IGBT modules.
The IGBT production line has higher and more comprehensive requirements for production timing, test stability and equipment reliability. After receiving the order, under the overall guidance of the company’s senior management, the Product Management Center assigned a group of experienced engineers in mechanical design, electrical design, automation design to set up a technical team to focus on completing the optimal design of the program, energy-saving production evaluation and production line layout planning. at the same time ,while conducting stability and feasibility testing and verification of the key processes in the program. The Production Operation Centre focuses on the resources of all parties, collaborates efficiently, and continues to fight for the completion of the production and manufacturing tasks on time and in quality and quantity. The quality center does not spare any detail from process control to final inspection and debugging.
After several months of hard work, Second Intelligent overcame all the difficulties and has completed the manufacturing and in-house debugging of more than ten lines of the IGBT project.
The technical solution of the IGBT automatic gluing, framing and baking section realises digital, intelligent and automated production through effective management of all production links, so that the production line runs efficiently and stably. This technical solution is configured with process equipment such as marking machine, gluing machine, automatic screwing machine, pressure ring pressing machine, in-line oven, etc., which ensures that the products produced have higher yield of encapsulation test, more stable parameters and better reliability. It can carry out laser marking, code scanning, dispensing, visual inspection, assembly, screwing, compression ring loading, baking and other various processes, the flexibility of module configuration to complete the integration of various automation applications, to get rid of the past automation platform function of the disadvantages of a single.
The open interface of the whole line is docked with the customized MES management system of Second Intelligent, which can obtain various information of the production line required by customers in real time through the MES management system, such as program usage, real-time status of equipment, historical alarm information, etc., to realize the informatization, intelligence and unmannedness of the production process, etc., so as to realize the transformation from manufacturing to intelligent manufacturing and accelerate the industrial upgrading.
The project adopts Second Intelligent’s self-developed dispensing valve, which can effectively solve the problems of uneven dispensing, broken glue, leakage, overflow and other bad problems, and the dispensing path can be edited by itself. The visual inspection system developed by Second Intelligent will visually inspect the finished dispensing product of the previous process to detect whether it is broken, leaking, overflow and other defective problems, AOI inspection such as qualified transfer mechanism will transport the shell to the next process for the next operation, AOI inspection such as unqualified will be transported to the outside of the equipment through the transfer module by the NG conveyor line, so as to ensure that the system without stopping. This ensures that the system can automatically eject the faulty products without stopping and improves the stability of the dispensing system.
Second Intelligent focuses on fluid application and service, is committed to promoting the intelligent upgrading of fluid application in the industrial equipment industry with technology and innovation. At present, the self-developed IGBT coating and assembly line solution has solved the problem and improved the performance for many customers, such as famous brands of new energy vehicles, demonstrating the company’s strong strength in design, project management and production quality, and laying a solid foundation for the expansion and cooperation of subsequent projects.
