The following seven processes explain the steps involved in battery manufacturing.
The primary processes of battery production equipment include vacuum mixers, coating machines, calendering machines, etc. The intermediate processes involve die-cutting machines, winding machines, stackers, electrode filling machines, etc. The final processes involve forming machines, grading inspection machines, storage logic, etc. Additionally, battery production also requires packaging automation equipment. Packaging is a crucial process in the production, design, and application of battery power systems.
I. Laser Welding Process for Nickel
The traditional aluminothermic welding requires multiple workstations, which wastes resources and is difficult to operate. Additionally, in the traditional soft battery negative electrode lug welding process, the lug is bonded to nickel. This requires cutting the wire nickel strip into fixed-length pieces, and then workers hold the battery with one hand and the nickel plate with the other, placing it on the laser machine and using the eyeball to fix and weld. The excess nickel strips in the weld lug will be cut by the workers. All of these operations are carried out manually, resulting in low efficiency, poor consistency, and unguaranteed quality. In the new nickel welding process, Grappe has adopted a new laser welding technology for nickel. Laser welding has quality assurance, with almost no welding head wear or tearing, and the intelligent one-click adjustment of the machine allows for quick and automatic size switching. Test data shows that the laser welding unit pays more attention to important indicators such as internal resistance and discharge rate, and has higher consistency.
II. Intelligent Grading
GANDY intelligent classification technology applies artificial intelligence methods to the intelligent classification of various data sets. A large number of samples form the input data set, and the machine can be automatically adjusted with a single click, quickly and automatically switching sizes. The testing machine can be set at regular intervals, reset, and automatically calibrated, displaying which level it belongs to. At the same time, samples can be automatically imported into the system, and various attributes can be precisely divided, automatically completing the classification unit, significantly reducing the risk of unit misjudgment. The intelligent data classification system analyzes known category products to automatically establish samples such as product K values, making the internal resistance of the products more consistent.
III. Automatic adhesive tape after reaching the top height
GANDY adopts the capped automatic tape technology, filling the gap in the configuration. The intelligent adjustment of the machine enables automatic and rapid switching of numbers, improving the consistency of the connection positions. It also has functions such as anti-leakage, waterproofing, sound insulation, and heat insulation. Compared with the traditional operation mode, its operating efficiency has increased by three times. At the same time, all the test data are automatically uploaded to the system, greatly improving work efficiency and accuracy.
4. Weighing and scanning after side sealing
GANDY adopts the side sealing and weighing scanning technology. On the machine frame, there is a rotating drive mechanism. Through this rotating drive mechanism, the rotation angle can be precisely controlled for positioning. The soft-shell lithium batteries are clamped by the clamping machine, and at the same time, the upper and lower sealing structures on both sides of the turntable are used for sealing. The P and the battery side are smartly scanned, automatically weighed, automatically reset to zero, including the internal corrosion test. The results will be automatically uploaded to the system. This process has a simple and compact structure, accurate positioning, and improves the overall production efficiency.
V. Traceability System
The GANDY追溯 system collects feedback information on processes such as digital identification management, production, personnel, equipment, materials, and production time, and provides information on production procedures and sales， etc. It records the products to improve product quality. It can prevent accidental production incidents during the production process and enable accurate targeted recalls when problems occur. At the same time， by scanning the product identification code， consumers can also obtain information about the product， thereby enhancing the safety of the product and the trustworthiness of the brand.
VI. Automatic Collection of Environmental Data
The automatic data collection function of the GANDY environment system is mainly used to collect the temperature and humidity data of the workshop’s environmental operation, enabling environmental monitoring and control. The collected data is uploaded, saved, analyzed, and processed. Standard values are set to activate the alarm reminder function, ensuring that accurate data is promptly transmitted. It is then distributed to relevant process departments to handle the production dynamics of the workshop, provide real-time guidance, respond and report, significantly enhancing the ability to solve problems and promoting the process of intelligent manufacturing in the enterprise’s workshop.
VII. Centralized Control System for Baking
GANDY designed a centralized baking control system, which can be operated in a single operation or in multiple combined group operations. This system can upload the oven temperature and vacuum degree to the display screen in real time. It will display alarms for data that does not meet the indicators, and record the entire process in the system in real time. The PDA scans the opening control system and provides the experimental test results. This system centrally monitors various functions, providing effective protection for the injection process and having good real-time performance and stability.
