PV Cell Screen Printing Line

This modern printing line is fully automated and integrates multiple stations, typically including loading, buffer, alignment, multi-pass printing (two passes on the front and two on the back), vision inspection, sorting, and unloading modules. Its core components include the high-rigidity printing platforms, CCD-based alignment systems with micron-level precision, servo-driven squeegee units, automatic paste supply systems, and an intelligent process control system. The line supports advanced technologies such as SMBB (Super Multi Busbar), 0BB (Zero Busbar), and fine-line printing (line width ≤25μm).

Technological Advantages

Ultra-high printing accuracy and repeatability (accuracy ≤±6 μm, line width control capability down to 20–30 μm), high capacity and flexible manufacturing (4800–5200 pcs/h), and intelligent operation with yield assurance (integrates AI-powered AOI).

Key Parameters

Suitable for 182mm (M10) to 210mm (G12) cells
Supports rectangular cells and half-cut cells
Cell thickness: 100–180 μm (customizable down to 80 μm)
Printing passes: 2 on front (fingers + busbars) and 2 on back (fingers + busbars)
Printing accuracy: ≤±6 μm; line width uniformity: ±2 μm
Minimum line width: 20–25 μm (depending on paste and plate)
Capacity: 4800–5200 pcs/h (182mm)

One line covering the whole printing process

The screen printing line includes printing, drying, firing, annealing, sorting and inspection.

Super short cycle time

The use of high speed linear motor, the alternate motion of four platforms together with the self-developed closed-loop control system can reduce the cell conveyance time and achieve super short cycle time.
High precision

Separate motion control combining self-developed visual recognition and algorithms make high precision printing possible.
Strong expandability

Support 182-230 full or half-cut cells; easy and fast switchover by changing certain module, lengthening the service life of machine.
