    Equipment Performance 

    Tabber&Stringer SGT1500 adopts IR soldering method, servo motor driving and Industrial CCD positioning&detection for defective solar cell excluding automatically. The soldering effect, such as cell spacing, cell numbers of single string, soldering temperatures and etc, can be adjusted according to requirements. SGT1500 can be integrated with automatic layup machine to achieve the composing and locating of solar cell strings on tempered glass.


    ◆Motor drive guide rail cell positioning.

    ◆High speed electric cylinder cell classification handling and positioning.

    ◆Flux accurate and quantitative smear.

    ◆Original ribbon flexible pressure holding mechanism.

    ◆Infrared heating, subsection soldering, closed loop control of soldering temperature and power, temperature raise smoothly and small heat shock, effectively reduce the solar cell breakage rate.

    ◆This equipment soldering 156×166mm ×1/2、1/3、1/4 solar cell, can realize mono-crystalline solar cell multiform soldering.

    Can realize mono-crystalline solar cell (min 1/3) chamfer to the front, back and right angle middle soldering.
