Cylindrical Lithium Battery Producer (DC1860B)
    Publish time 2017-03-20 16:38    

  Cylindrical Lithium Battery Producer (DC1860B)

    This equipment DC1860B, DC1860C type positive / negative pole automatic welding machine is mainly applied to the lithium ion battery cathode / negative pieces of continuous strip after welding pole paste protection tape and winding, the machine mainly by the pole piece unwinding and correction mechanism , The ear-welding mechanism, the pole piece buffer device, the pole piece paste tape device, the pole piece winding device composition, the machine automation degree is high, the production efficiency is high, the consistency is good.

 

一、Equipment technical functions

  1. This machine is mainly used for lithium ion battery pole piece automatic welding ear
  2. Pole and pole pieces after welding the front of the paste, the opposite paste glue
  3. The machine adopts the high-end Mitsubishi PLC bus control mode, realize the very ear material material discharge, the shear, the pole piece welding, the positive and negative surface glue, the winding automation, saves a lot of manpower, the pole piece in the production process man- Reduce the high efficiency of welding, to achieve the upper and lower adhesive (2)
  4. Pole piece welding, paste tape can be automatically wound, for automatic winding machine
  5. This machine is in the pole piece production in the high degree of automation equipment, this equipment and continuous pole piece rolling, continuous pole piece composition pole piece automatic production
  6. The machine has positive and negative pole up and down adhesive tape, special ear tape.
  7. The machine is running all electrical failure, there are alarm tips

Equipment supportingThis set of equipment from the ear to send / shear institutions, automatic welding equipment and ear pole and ultrasonic welding machine, up and down adhesive device, correction system, electrical control system.
