Lithium battery equipment generally refers to a variety of manufacturing equipment used in the production of lithium batteries, and the manufacture of various types of lithium-ion batteries can be uniformly divided into four process sections: electrode production, cell assembly, cell activation detection and battery packaging.
The electrode piece manufacturing process includes stirring, coating, rolling, slitting, film production, tab forming and other processes, which is the basis of lithium-ion battery manufacturing, and has high requirements for the performance, precision, stability, automation level and production efficiency of the electrode piece manufacturing equipment; The cell assembly process mainly includes winding or lamination, cell pre-packaging, electrolyte injection and other processes, which have high requirements for precision, efficiency and consistency; The cell activation detection process mainly includes cell formation, capacitance detection, etc.; The battery packaging process includes testing, classification, series-parallel combination of the single cells that make up the battery pack, and testing the performance and reliability of the assembled battery pack.
Today we are talking about the automation equipment of the lithium battery assembly process!
1. Cell capacity detector
Cell detection requires the use of a cell capacity detector to detect the cell capacity, rate, number of cycles, and whether it meets the requirements of use.
2. Lithium battery sorting machine
Lithium battery sorting machine is a cylindrical battery internal resistance and voltage test sorting equipment, with high-precision internal resistance and voltage automatic test system. The internal voltage and resistance values are set on the computer software and sent to the specified gear position and the internal resistance of the lithium battery voltage detection results The classifier generates classification data analysis and generates a chart and a histogram to facilitate the visual statistics and display of mass production quality. The inspection system has a database function, which can query and count historical inspection data. According to the battery performance parameters, sorting lithium batteries is an essential key step.
3. Lithium battery sticker barley paper
Need to use lithium battery sticker barley paper machine. Lithium batteries affixed with barley paper can prevent the positive electrode and the positive electrode from colliding together and cause a short circuit when working, and can also prevent dust from entering the gap. Barley paper itself has good wear resistance and aging resistance, and also has the role of voltage resistance, so when people touch electronic products, no electric shock will occur, and it will not destroy some performance effects of barley paper itself. Then there are some special properties of barley paper: barley paper has good insulation, and putting barley paper on the market of many dangerous electronic products is very safety belt. And also has good mechanical strength, high electronic strength, as well as flexibility, water resistance, wear resistance, grease resistance, aging resistance and many other properties.
4. Lithium battery spot welding machine
It is used for manual welding of batteries and nickel-plated steel strip or nickel strip in cylindrical/polymer battery combination, and ensures that the welding tension of the battery and nickel-plated steel strip or nickel strip is greater than or equal to 30N, and the welding voltage locking technology prevents the mesh voltage fluctuation from affecting the welding current; The welding pulse width is adjustable, the welding spatter is small, and the welding joint does not change color. It has the function of two-stage current detection and comparison, abnormal current sound and light alarm, effectively prevents the occurrence of false welding phenomenon, and has fault self-diagnosis function, showing the corresponding fault points, which is convenient for maintenance.
5. Battery tester
The production of these rechargeable battery needs has produced a specialized rechargeable battery comprehensive detector, where testers can quantitatively and accurately measure some basic parameters of the battery. It can measure the open circuit voltage, internal resistance charge, discharge performance, battery capacity of the battery. Especially lithium battery function, overcharge protection, overdischarge protection, overcurrent protection, short circuit protection, etc. And measuring the corresponding value is very convenient, battery production, pre-sales and after-sales service work, using a very simple few steps, can visually determine the performance and quality of the battery. However, there is also a road complaint screening function, which can set the upper and lower limit measurement parameters, which can simply and quickly detect a batch of defective battery products, improving production efficiency.
6. Lithium battery aging cabinet
By checking whether the battery is qualified by the charge and discharge cycle of the battery pack, it is like we have produced some battery packs for electric vehicles, and we cannot immediately put it on the shelf and sell it. If the customer asks us how long it takes to charge the battery pack, how long does it take to fully charge the battery. These data are to be clear and can be measured, so there is lithium battery assembly and processing equipment - lithium battery aging cabinet. The function of the battery aging cabinet is to simulate how long the battery pack can be used once charged.
