Cell color sorting and defective detection system is fully automatic visual inspection equipment, researched & developed by Visual as the important station to ensure only the qualified cells entering in or leaving out factory, which is high efficient equipment to complete sorting and defection within 1 second per cell.

It consists of: main frame, loading, image collection and processing, unloading and control etc.

Utility Requirement: 0.6~0.8 MPa,220V,50Hz
Cells to inspect
Size: 125mm*125mm /156 mm*156mm
Material: Monocrystalline and polycrystalline

Items to detect
1. Mechanical defective (edge breakage, notch, broken angle, cracks, pinholes, dimension of side and diagonal line, crystalline silicon peeling etc.)
2.Contamination (besmirch, fingerprint, oil dropping etc.)
3. Printing Defectives (paste leakage or knot,main grid line, sub grid line, color changing of grid line, printing deviation, drop of electrode, back electrode, back electrical field etc.)
4.Color spot (diffused graphite boat mark, uncoated, spot, blushing cell, hot spot, hot point, etch color spot, water mark etc.)
