Product Description

Machine features:

-Integrated monolithic welding and in-line machine rework function

-Equipped with a string EL detection function to determine the location that needs to be repaired and detect the results after repair.

-Comes with string alignment and visual positioning measurement function.

-Automatic completion of the need to replace the piece of the culling, supplementary repair.

-The system detects that if there is deviation of welding belt and virtual welding, it can be repaired automatically without changing pieces.

-It can be used alone, or it can be used in parallel with the string welding machine and the typesetting machine.

-Comes with welding belt stamping function.

-A full set of Mitsubishi PLC and integrated electronic control and servo system drive control, that is, machine system control.

Serial Number Project Parameters Remarks
1 Basic information Single chip welding machine beat 23S/piece  
Battery String Repair Beat 43S (repair monolithic) The number of pieces to be repaired in a single string increases, and the time will also increase by 16-20S/piece.
Fragmentation rate 0.20% (half-slice) monthly average fragmentation rate in slices
Welding method infrared welding  
Flux method Welding strip soaking method,  
overall yield ≥ 97%  
Equipment movement rate ≥ 97% Does not include maintenance time
2 Battery slice Cell Size Compatible with 166mm * 166mm-220*220 half/three/four slices The standard configuration is a cell grid wire specification, other cells are optional, paid upgrade.
Battery sheet feeding method Slice feeding  
Number of main grid lines Compatible with 5BB-12BB  
Cell thickness 130μm-210μm  
3 battery string Maximum string length L≤1000-1300mm  
Misplacement of piece after repair ≤ 0.5mm  
Battery string input, output height: 1110±10mm  
Radian of incoming material string 2~5°  
Straightness error of string after repair ±0.5mm  
Positioning mode Main grid line positioning contour positioning  
Sheet spacing 0.5--3mm  
Battery string-out interface Can be docked typesetting machine can also be used stand-alone  
String EL detection Can detect missing angle, fragment, edge collapse, etc., with defects> 0.2mm; Welding belt lap short circuit; Mixed gear; Battery piece black heart, defect> 5mm; Front virtual welding, empty welding and over welding. The virtual welding of a single welding belt exceeds 10mm; scratches, the length of the scratch is> 5mm, and the image is visible;  
4 Welding strip Welding strip size Circular welding strip φ0.2-0.40mm  
Roll weight of welding strip ≤ 10Kg  
Welding strip stamping 0.1-0.13mm  
I-wheel Market conventional standards  
Cutting accuracy of welding strip ≤ 1mm  
Welding strip parallel connection range 5-10mm  
5 Docking Requirements Battery string input, output height: 1110±10mm  
NG String The battery string entering CF100 needs to determine the front and back sides (back up, negative forward, positive backward)  
Requirements for docking with typesetting machine The docking height of string transmission and the length of extended string repair machine shall be determined in advance for docking with typesetting machine.
