Analysis of lithium battery manufacturing and assembly equipment

Lithium battery manufacturing equipment Generally speaking, the lithium battery process is roughly divided into three stages: pole piece production, battery cell assembly, and battery packaging. The corresponding lithium battery equipment can be divided into front-end, middle-end, and back-end. Front-end equipment includes mixers, coating machines, slitting machines, etc.; mid-end equipment includes winding machines, stackers, liquid injection machines, etc.; back-end equipment includes chemical conversion cabinets, sub-container cabinets, test equipment, PACK automation equipment, etc. In terms of the economic proportion of all processes, the value distribution of the front, middle, and back products is about 4:3:3. Among them, the coating machine and the winding machine are the most technically difficult and the value is the largest. Each process stage equipment in the lithium battery manufacturing process can significantly affect the battery performance, but the detailed effects are not the same. The coating density of the front equipment and the degree of roller compaction will affect the use of pole piece current collection; if the quality of the middle equipment used for cell assembly is unqualified, it is easy to cause leakage; and the module and PACK design of the latter Unreasonable will also lead to poor heat dissipation of the battery pack and affect the normal operation of the lithium battery. In the integration process of the back-end battery pack, unreasonable packaging design will also cause large internal losses in energy density. In addition, processing efficiency and yield have a distinct barrel effect, which depends on the process with the lowest efficiency and yield in the processing line. Therefore, the equipment in each process of lithium battery processing can significantly affect the economic benefits of battery manufacturers. The complete set of assembly equipment for lithium battery packaging equipment has four parts: raw material testing equipment, finished product manufacturing equipment, finished product testing equipment, and finished product packaging equipment. The complete set of equipment includes general equipment and intelligent automatic equipment. Lithium battery packaging equipment includes: ball mushroom machine, blast oven, vacuum oven, vacuum mixer, coating machine, tying machine, slitting machine, slitting machine, riveting machine, winding machine, heating shaping machine, Shell centrifuge, vacuum automatic liquid filling machine, vacuum sealing machine, steel ball automatic sealing machine, spot welding machine, tunnel furnace, current. voltage, resistance detector, Haiba pump.
