Disc battery electrode punching and cutting process
Cut the coated continuous cathode and anode electrode to the length and size that conforms to the battery cell. The cutting equipment can set the cutting length, quantity, speed, separate cutting, and has automatic rewinding and unwinding functions, tension Controls automatic feeding and stopping, easy loading and unloading.
Battery cathod and anode electrode slitting
It is mainly used for roll-cutting and slitting of positive and negative electrode sheets after battery coating. The wide electrode sheets are divided into multiple strips, and the edges of the slices are neat to ensure dimensional accuracy.
Weld the battery tabs to the electrode
Ultrasonic tab metal spot welding machine is generally used for metal welding in winding and lamination processes (tab welding, tab and electrode welding). It has the characteristics of small size, beautiful appearance, easy operation, solid structure, stable and safe use. In laboratory welding, ultrasonic welding is usually used, not laser welding
Wind the positive and negative electrode sheets and separator into a battery cell
The laboratory small winding machine is specially used for the core winding process of aluminum foil Cylindrical cell/pouch cell batteries. the positive and negative electrode sheets and separators are manually wound into battery cores. Easy to operate, safe and reliable
Single-pin spot welding of cylindrical battery negative electrode plate and casing
Using AC pulse spot welding machine (single needle spot welding), controlled by microcomputer microcontroller, the performance is more stable and reliable. It is a necessary equipment for the production of cylindrical lithium batteries.
Fixed position of cylindrical battery cells
The cylindrical battery with the battery core and no seal is rolled and grooved (to compress the battery space and fix the battery core). The mold can be replaced and is suitable for a variety of batteries such as 18650, 21700, etc.
Welding of battery positive tab and cylindrical cap
The ultrasonic spot welder can not only weld pole pieces and tabs.
It can also be used to weld the positive electrode sheet and battery cap.
The battery electrolyte is standing in a vacuum environment
This high-efficiency equipment integrates vacuum mixing and dispersion. It is suitable for the mixing process of positive and negative electrode slurries in battery experimental research. It is completely bubble-free.
Final sealing of cylindrical cells
The small manual hydraulic cylindrical battery sealing machine is mainly used in the production of cylindrical batteries, and the final sealing and molding of cylindrical batteries.
