Cylindrical lithium battery winding machine (DC1860A)

一、Equipment description

  The device DC1860A cylindrical lithium battery cell winding machine, suitable for a variety of cylindrical lithium battery cell winding. The machine has a high degree of automation, high production efficiency and good consistency.


二、Equipment technical functions

  1. This machine is mainly used for winding process of lithium ion battery batteries;
  2. The machine diaphragm and pole pieces are used to control the tension, the use of servo discharge and correction;
  3. Tension the size of the use of proportional valve control, set in the man machine;
  4. Pole piece in the volume before the needle is also added correction function;
  5. The machine has a first roll diaphragm, the first roll negative pole function, can be used alone one of the functions can also use its two functions
  6. The machine uses high-end Mitsubishi PLC bus control, to achieve pole pieces and diaphragm discharge, feeding, winding, paste glue, take material automation. Save a lot of manpower, the battery in the production process of human damage rate greatly reduced
  7. The machine has automatic core package cutting, core package short circuit detection function
  8. Diaphragm has a static function
  9. The machine is running all electrical failure, there are alarm tips

Equipment supporting: This set of equipment from the pole piece, diaphragm discharge mechanism, correction mechanism, feeding mechanism, cutting body, winding mechanism, cutting mechanism and electrical control system.
