Auto Cutting&Breaking Machine: Model YHZD-2000 (Feature Product)

2000pcs/ Hrs high speed for 1/2 cell  0.3% fail rate


Operation Procedure:

1. The feeding arm rotated 180 degree automatically after the storage box was feeded by cell.          

2.  Cell positioning twice then edge positioning.           

3. Vacuum sucker feeding accurately controlled by servo;           

4. Cell cutting and Pick;          

5. Cell sucked to transfer platform and put the on the platform to save the cell taking time.

6. The pick module is a vacuum sucker structure with two arms. One arm takes the cell and puts them on the breaking table, while the another arm takes the two half cells which are breaked on the breaked table and puts them on the discharging module.            

7. Automatic mechanical breaking by simulating manual breaking which will not affect the cell efficiency ;           

8. The unloading module will transfer two-half cells into the half-piece box in two directions automatically, this part can also be customized according to different demand.
