Directly address the pain points of module/PACK automation technology

　　With the development of the modernization process and the advancement brought by "Industry 4.0", the production equipment of the lithium battery industry has gradually transformed and upgraded from the previous workstations/semi-automatic production lines/automatic production lines to intelligent production lines.

　　There are also some inevitable problems that occur during the entire manufacturing process. It is precisely because of these "pain points" that a group of excellent automation equipment manufacturers "came into being" in the face of difficulties.

　　On December 16, the "Li Yuanheng·2019 Senior Engineer Lithium Battery & Electric Vehicle Annual Conference" was held grandly at the Hyatt Regency Shenzhen Airport. As the largest and most attended annual event in the lithium battery and electric vehicle industry, the event attracted more than 800 corporate executives from the entire new energy vehicle industry chain including materials, equipment, batteries, BMS, PACK, complete vehicles, and operation and leasing.

　　At the meeting, Fu Wenhui, general manager of Shanghai Sikeqi Automation Engineering Co., Ltd. (hereinafter referred to as "Sikeqi"), delivered a keynote speech titled "Talk directly to the pain points of module/PACK automation technology".

　　Fu Wenhui said that there are six major pain points in terms of hardware in the power battery manufacturing module and PACK process. The first is the diversity of production line layouts, the second is the diversity of interface forms, the third is the diversity of product sizes, and the fourth is the variability of the process. , the fifth is the high requirement for detection accuracy, and the sixth is the production penetration of the module-PACK production line.

　　To this end, the solution proposed by Sikeqi is:

　　1. Based on factors such as Pack, module structure characteristics, and process characteristics, design diverse standard workstations (SPF-hang) and standard material racks (SOV-trans), enrich the standard structure of workstations, and simulate the overall process.

　　2. Analyze the Pack, module interface and appearance structure, and develop a variety of grippers (SPS-grip) and transport trolleys (SPV-trans/SSV-trans) for automatic and manual workstations.

　　3. Analyze the process characteristics of PACK and modules, actively absorb the latest technologies in related industries, establish relevant laboratories, and test the functional applications and stability of equipment.

　　4. Promote the establishment of intelligent logistics systems between production lines to achieve point-to-point material transportation, combine with the MES system, establish dual channels for material/information transmission, and completely achieve complete penetration between upstream and downstream production lines.

　　In terms of software, it is also inconvenient to query the MES system and difficult to interact with third-party systems; MES saves a small amount of data and is slow to query data; the production line can only produce a few specific products, and new products cannot be produced quickly; new employees Unfamiliarity with the process flow and unskilled operation lead to production problems; MES and PLC interactive control hardware are slow and prone to interaction problems, etc.

　　For software system problems, Sikeqi also has five major solutions:

　　1. The front-end and back-end data interaction adopts the international standard Webservice interface. Data access is safe and efficient, and data interaction with third-party systems is possible.

　　2. Using distributed technology, data can be saved for several years or even more than ten years. Data query uses big data processing technologies such as caching and middleware to quickly query the desired data in large amounts of data.

　　3. MES adopts a flexible design concept. When adding new products, you only need to simply add configurations in the background to produce new products, make full use of the production line, and even produce mixed lines.

　　4. Each work station is equipped with a visual terminal that displays operating instructions. Employees only need to follow the prompts to produce products correctly.

　　5. Use software to directly control equipment, shorten the delay time of intermediate links, greatly improve information collection efficiency and equipment utilization, save costs and improve production efficiency, and also make the production line more flexible.

　　"At the same time, Sikeqi also conducts simulation and rhythm analysis of the process." Fu Wenhui revealed that various aspects of ergonomics simulation, robot position and posture simulation, mechanism degree of freedom simulation, etc. are used to simulate the overall operation of individual equipment and workstations. situation; provide optimization suggestions for rhythm and structure during the design phase, and can integrate PLC control virtual debugging during the debugging phase.
